Description

The present invention relates to a stove.

Conventionally, there is known a stove with a design panel attached to the front of the stove body (see, for example, Patent Document 1). The design panel is attached to the front of the stove body in order to decorate and protect it. In addition, a stove has been proposed in which multiple patterns of design panels with different designs are prepared, and the design can be changed by changing the design panel to suit the user's preference.

JP 2011-52841 A

With the stove described above, the design panel had to be replaced manually every time the design was changed, which was a time-consuming task. In addition, there was a problem in that the number of designs for the design panel was limited, which meant that costs were incurred for each design.

The object of the present invention is to provide a stove whose design can be easily changed.

The stove of claim 1 is a battery-powered stove having a main body and a top plate provided on the top of the main body, and is provided on at least one of the front of the main body and the top plate, and is composed of electronic paper capable of retaining display content and being electrically updated, and is equipped with a display panel capable of displaying a design image, a display control unit that displays and updates the design image on the display panel , a receiving unit that receives image information corresponding to the design image from the outside via a wired or wireless connection, and a memory unit that stores the image information received by the receiving unit, and the display control unit displays and updates a plurality of images corresponding to the plurality of image information stored in the memory unit in a random or specified order on the display panel when the stove is turned on and off .

The stove of claim 2 may include a grill compartment provided inside the main body and a grill door provided on the front surface for opening and closing the opening of the grill compartment, and the display panel may be provided on at least one of the left and right sides of the grill door on the front surface.

The stove of claim 3 may include a selection unit that selects one or more of the image information from the image information stored in the memory unit, and the display control unit may update and display on the display unit the design image corresponding to the image information selected by the selection unit.

According to the stove of claim 1, a display panel made of electronic paper is provided on the front or top plate of the main body, which is easily visible to the user, and the design image is displayed and updated on the display panel, making it easy to change the design of the stove. Since the design of the stove can be changed simply by displaying a design image on the display panel, there is no need to replace decorative panels with different designs as in the past, and the cost of preparing them is also unnecessary. In addition, since the display panel is made of electronic paper, the design image can be held on the display panel without consuming power even when the stove is not in use, so the exterior design of the stove can be maintained. In addition, a design image imported from outside can be displayed on the display panel. Therefore, the user can import a desired design image (e.g., a picture, a photo, etc.) into the stove and display it on the display panel. Therefore, the user can easily create an exterior design to his or her liking. Furthermore, since multiple design images are displayed and updated randomly or in a specified order when the stove is turned on and off, a novel stove in which the exterior design of the stove changes automatically can be provided. In addition, by displaying and updating randomly, a sense of expectation can be created in the user because the next updated design image cannot be predicted.

According to the stove of claim 2, a display panel is provided on the front panel of the main body, so that the appearance of the stove when viewed from the front by the user can be strongly impressed by the design image displayed on the display panel.

According to the stove of claim 4, a desired design image can be selected from design images imported from outside and displayed on the display panel, making it easier to create an exterior design to one's liking.

The following describes an embodiment of the present invention. The external configuration, electrical configuration, and control processing of the device described below are not intended to be limiting, but are merely illustrative examples, unless otherwise specified. The drawings are used to explain the technical features that may be adopted by the present invention.

The structure of the stove 1 will be described with reference to FIG. 1. The stove 1 is a built-in stove. The stove 1 comprises a housing 2 and a top plate 3. The housing 2 is open at the top, and the top plate 3 is installed in the opening. On the top surface of the top plate 3, a right burner 4 (hereinafter referred to as the right burner 4) is provided at the front right, a left burner 5 (hereinafter referred to as the left burner 5) is provided at the front left, and a back burner 6 (hereinafter referred to as the back burner 6) is provided at the back center. A number of flame holes are provided on the side of each of the right burner 4, left burner 5, and back burner 6. An ignition electrode and a thermocouple 53 (see FIG. 5) of an igniter 51 (see FIG. 5) are provided near each of the right burner 4, left burner 5, and back burner 6 so as to face the flame hole. When the igniter 51 is driven, a spark discharge is generated at the ignition electrode, igniting the gas ejected from the flame hole. Thermocouple 53 is heated by the flame formed in the burner hole and generates a thermoelectromotive force. Stove 1 can detect the flame going out in right burner 4, left burner 5, and back burner 6 based on the thermoelectromotive force generated in thermocouple 53.

A thermistor 52 protruding upward is provided approximately in the center of each of the right burner 4, the left burner 5, and the back burner 6. The thermistor 52 is pressed down in contact with the bottom of a pot placed on the trivet to detect the temperature of the bottom of the pot. An exhaust port 7 for a grill device (not shown) installed in the housing 2 is provided at the rear of the top plate 3. A grill door 10 is provided approximately in the center of the front of the burner 1. The grill door 10 opens and closes the front opening of a grill chamber (not shown) installed in the grill device. A grill burner (not shown), an igniter 51, a thermocouple 53, etc. are provided in the grill chamber. The grill burner heats food to be cooked on a grill grate (not shown) placed in the grill chamber. The ignition electrode of the igniter 51 and the thermocouple 53 are provided so as to face the flame hole of the grill burner.

The right panel section 8 is provided in the area to the right of the grill door 10. The right panel section 8 has an upper panel 81 and a display panel 82 on the front. The upper panel 81 is formed in a rectangular shape when viewed from the front, and covers the upper half of the front of the right panel section 8. The upper panel 81 is provided with two operating knobs 11 and 12. The operating knobs 11 and 12 are provided side by side in the horizontal direction, and are operated to ignite, extinguish, and adjust the flame of the right stove 4 and grill burner.

The display panel 82 is electronic paper formed in a rectangular shape when viewed from the front, and covers the lower half of the front surface of the right panel section 8. A design image is displayed on the display panel 82. A design image means an image designed with, for example, letters, symbols, figures, patterns, pictures, photographs, etc. When the display panel 82 is pressed with a finger, the operation panel 23 (see FIG. 5) fixed to the back surface of the display panel 82 is rotated forward from the bottom as a base point and pulled out by a well-known push-push mechanism (not shown). Although not shown, the operation panel 23 is provided with an operation section for performing various settings of the right burner 4 and the grill device, a display section for displaying the timer time, etc. The display section of the operation panel 23 is a 7-segment display or liquid crystal, etc., but may be electronic paper like the display panel 82.

The left panel section 9 is provided in the area to the left of the grill door 10. The left panel section 9 has an upper panel 91 and a display panel 92 on the front. The upper panel 91 has two operation knobs 13, 14. The operation knobs 13, 14 are arranged side by side in the horizontal direction and are operated to turn on, turn off, and adjust the flame of the rear burner 6 and left burner 5.

Like the display panel 82, the display panel 92 is electronic paper formed into a rectangular shape when viewed from the front, and covers the lower half of the front surface of the left panel unit 9. Like the display panel 82, a design image is displayed on the display panel 92. The display panel 92 is attached to the front surface of the left panel unit 9 so that it can be opened and closed, with its left end portion as an axis. When the display panel 92 on the left panel unit 9 is opened towards the front, a dry battery box (not shown) is exposed. The dry battery box stores dry batteries 17 (see FIG. 5).

When the display panel 92 is closed and pressed with a finger, the operation panel 24 (see FIG. 5) fixed to the back of the display panel 92 rotates forward from its lower part and is pulled out by a well-known push-push mechanism (not shown). Although not shown, the operation panel 24 is provided with an operation section for making various settings for the left burner 5 and the rear burner 6, a display section for displaying the timer time, etc. The display section of the operation panel 24 is a 7-segment display or liquid crystal, etc., but like the display panel 92, it may be electronic paper.

It is desirable that the display panels 82 and 92 are capable of displaying and updating even when the voltage is below the minimum voltage required for the operation of the stove 1.

The design change function of the stove 1 using electronic paper will be described with reference to Figures 1 to 4. As described above, the display panels 82, 92 are well-known electronic paper that can hold the display contents and can be electrically updated. The display panels 82, 92 can display design images in two colors, for example, black and white. The design of the stove 1 can be easily changed by displaying and then updating design images on the display panels 82, 92. When the stove 1 is viewed from the front in a non-operating state (with the operation panels 23, 24 stored), the display panels 82, 92 are located in the lower half of both the left and right sides of the central grill door 10, respectively, and face the front, so that the exterior design of the stove 1 can make a strong impression on the user.

Figures 1 and 2 show the design image of pattern 1 displayed on the display panels 82 and 92. The design image of pattern 1 is a checkerboard pattern of black and white grids. Figure 3 shows the design image of pattern 2 displayed on the display panels 82 and 92. The design image of pattern 2 is a diagonal pattern of black and white lines. Figure 4 shows the design image of pattern 3 displayed on the display panels 82 and 92. The design image of pattern 3 is a diamond grid pattern.

In this way, the exterior design of the stove 1 can be easily and freely changed by changing the design image displayed on the display panels 82, 92. In addition, because the display panels 82, 92 are electronic paper, the state in which the design image is displayed on the display panels 82, 92 can be maintained without consuming power.

The electrical configuration of the stove 1 will be described with reference to FIG. 5. The stove 1 includes a control circuit 30. The control circuit 30 includes a CPU 31, a ROM 32, a RAM 33, a flash memory 34, etc. The CPU 31 controls the overall operation of the stove 1. The ROM 32 stores various programs including a design mode setting program and a display control program. The design mode setting program is a program for executing the design mode setting process (see FIG. 7) described below. The display control program is a program for executing the display control process (see FIG. 8) described below. The RAM 33 temporarily stores various information. The flash memory 34 is non-volatile, and stores various data including an image data table 341 (see FIG. 6) described below, display order information, and the number of displayed images m.

The control circuit 30 is connected to a power supply circuit 35, a switch input circuit 36, a panel control circuit 37, display control circuits 61, 62, an igniter circuit 41, a thermistor circuit 42, a misfire detection circuit 43, a safety valve circuit 44, a solenoid valve circuit 45, a communication circuit 46, etc.

The board switch 21 and igniter switch 22 are connected to the switch input circuit 36. The board switch 21 is turned on and off in conjunction with the operation of the corresponding operation knobs 11 to 14. The switch input circuit 36 detects the state of the board switch 21 and inputs it to the power supply circuit 35 and the control circuit 30. The igniter switch 22 turns on after the board switch 21 turns on when the corresponding operation knob 11 to 14 is pressed in, and turns off before the board switch 21 turns off when the operation knob 11 to 14 is pressed back. The switch input circuit 36 detects the state of the igniter switch 22 and inputs it to the control circuit 30.

When the board switch 21 of any of the operation knobs 11 to 14 is on, the power supply circuit 35 supplies power from the dry battery 17 housed in the battery box to the various circuits. The power supply circuit 35 is turned on. When all of the board switches 21 of the operation knobs 11 to 14 are turned off, the power supply circuit 35 stops the power supply from the dry battery 17 to the various circuits. The power supply circuit 35 is turned off. The control circuit 30 operates when power is supplied from the power supply circuit 35, and stops operating when the power supply is cut off. A voltage measurement unit 351 is connected to the positive and negative poles of the dry battery 17. The voltage measurement unit 351 receives a control command from the control circuit 30, measures the output voltage of the dry battery 17, and inputs the measurement result to the control circuit 30 as a measurement signal.

The above-mentioned operation units and display units, etc., provided on each of the operation panels 23, 24 are connected to the panel control circuit 37. The panel control circuit 37 detects the operation of each operation unit and inputs the operation to the control circuit 30. The panel control circuit 37 receives control commands from the control circuit 30 and displays the timer time, etc., on the display unit of the controlled object.

The igniter circuit 41 receives control commands from the control circuit 30 and drives the igniters 51 provided in the burners 4 to 6 and the grill device of the burner 1. The thermistor circuit 42 inputs detection signals from the thermistors 52 of the burners 4 to 6 to the control circuit 20.

The misfire detection circuit 43 detects misfires in the burners 4 to 6 and the grill device based on the thermoelectromotive force generated by the thermocouple 53, and inputs the signal to the control circuit 30. The safety valve circuit 44 receives a control command from the control circuit 30 and controls the flow of electricity to the safety valve 54. The safety valve 54 is provided in each of the four gas supply pipes (not shown) that supply gas to the burners 4 to 6 and the grill device. The safety valve 54 is a magnetic safety valve that is mechanically opened by pressing the operation knobs 11 to 14, and is in an open state. The safety valve circuit 44 receives a control command from the control circuit 30 and energizes the safety valve 54. The safety valve 54 maintains its open state. For example, when a burner misfires in the burners 4 to 6 and the grill device, the thermoelectromotive force generated in the thermocouple 53 is lost, and the misfire detection circuit 43 inputs a misfire signal to the control circuit 30. The safety valve circuit 44 receives a control command from the control circuit 30 and cuts off the current to the safety valve 54. This causes the safety valve 54 to close due to the biasing force of a spring (not shown).

The solenoid valve circuit 45 receives control commands from the control circuit 30 and opens and closes the solenoid valve 55 for adjusting the amount of gas. The solenoid valve 55 is a gas shutoff keep solenoid valve. The solenoid valve 55 is provided in a bypass pipe (not shown) that branches off from the gas supply pipe and rejoins the gas. By opening and closing the solenoid valve 55, the flow path of the bypass pipe is opened and closed, and the amount of gas supplied to each of the various burners 4 to 6 and the grill device increases or decreases. This allows the heat of the various burners 4 to 6 and the grill device to be adjusted to two levels: high heat and low heat.

A short-range communication unit 56 is connected to the communication circuit 46. The short-range communication unit 56 can communicate with a short-range communication unit 56 (described below) of the smartphone 12 via Bluetooth (registered trademark). The communication circuit 46 receives a control command from the control circuit 30 and drives the short-range communication unit 56. The communication circuit 46 inputs information received by the short-range communication unit 56 to the control circuit 30.

The display control circuit 61 displays and updates the design image on the display panel 82 based on a control command from the control circuit 30. The display control circuit 62 displays and updates the design image on the display panel 92 based on a control command from the control circuit 30.

The image data table 341 will be described with reference to FIG. 6. The image data table 341 stores image data P1 to Pn of n design images externally input to the stove 1 using a smartphone 12 or the like, in association with an image number k (k=1 to n). The image number k is assigned sequentially in the order in which the image data P is input. The image data table 341 may store one or more image data in advance by default.

The design mode setting process will be described with reference to FIG. 7. The design mode is a format in which a design image is displayed and updated on the display panel 82, 92. In this embodiment, the user can select one of three design modes. The three design modes are a selection mode, a specified order mode, and a random mode. The selection mode is a mode in which a design image selected by the user can be displayed on the display panel 82, 92. The specified order mode is a mode in which the design images are updated sequentially in a specified order predefined in the image data table 341 each time the power of the stove 1 is turned on and off. The random mode is a mode in which design images are randomly extracted from the image data table 341 and updated sequentially each time the power of the stove 1 is turned on and off.

When setting the design mode, the user performs a setting operation for the design mode on the operation panel 23. The setting operation for the design mode includes, for example, the following operation steps.
(1) Close the gas valve and make sure that all control knobs 11 to 14 are returned to the off position.
(2) Press the control knob 11 of the right burner 4 to the ignition position.
(3) Within 10 seconds after performing step (2), return the control knob 11 of the right burner 4 to the off position.
(4) Within 10 seconds after performing (3), press and hold a predetermined switch (not shown) on the operation panel 23 for 3 seconds or more.

When the CPU 31 detects the operation of (4) above, it reads out the design mode setting program from the ROM 32 and executes this process. As shown in FIG. 7, the CPU 31 displays a mode number on the display of the operation panel 23 (S11). A mode number is assigned to each of the three design modes, with mode number = 01 being the selection mode, mode number = 02 being the specified order mode, and mode number = 03 being the random mode. Note that the initial display at the start of this process displays the default mode number, but it may also display, for example, the currently set mode number.

The user can change the mode number displayed on the display unit by using the + and - buttons (not shown) on the operation panel 23. The CPU 31 determines whether or not the decision button (not shown) on the operation panel 23 has been pressed (S12). The user presses the decision button with the mode number of the design mode they wish to set displayed on the display unit. Until the decision button is pressed (S12: NO), the CPU 31 returns to S11 and repeats the process. If the decision button is pressed (S12: YES), the CPU 31 sets the design mode of the mode number displayed on the display unit (S13). At this time, the CPU 31 stores the mode number of the set design mode in the flash memory 34.

The CPU 31 determines whether the set design mode is a selection mode (S14). The CPU 31 refers to the mode number stored in the flash memory 34, and if the set design mode is not a selection mode (S14: NO), the CPU 31 determines whether the set design mode is a specified order mode (S19). If the set design mode is a random mode (S19: NO), the CPU 31 ends this process.

If the set design mode is the designated order mode (S19: YES), the CPU 31 executes a display order acceptance process (S20). In the display order acceptance process, the CPU 31 accepts the display order of the design images on the operation panel 23. The display order is the order of the design images to be displayed on the display panels 82 and 92. The CPU 31 assigns a display number j to the design image to be displayed based on the accepted display order. Note that the design images that can be displayed on the display panels 82 and 92 in the designated order mode are the design images registered in the image data table 341. Note that all registered design images may be displayed in the display order, or only some of the design images may be displayed in the display order. The CPU 31 stores the display order information and the number of displayed images m in the flash memory 34. The display order information is information that associates the image number k of the design image with the display number j. The number of displayed images m is the number of design images to which a display number has been assigned, and is the number of design images to be displayed on the display panels 82 and 92. After the display order acceptance process is completed, the CPU 31 ends this process.

If the set design mode is the selection mode (S14: YES), the CPU 31 displays image number k on the display unit (S15). The default image number k is displayed initially, but for example, the currently set image number k may be displayed. The CPU 31 displays the design image of the displayed image number k on the display panel 82, 92 (S16). The user can check the currently set design image from the design image displayed on the display panel 82, 92. The user can change the image number k displayed on the display unit using the + button and - button provided on the operation panel 23.

The CPU 31 determines whether the image number k has been changed (S17). If the image number k has not been changed (S17: NO), the CPU 31 determines whether the decision button has been pressed (S18). If the decision button has not been pressed (S18: NO), the CPU 31 returns to S17 and repeats the process. If the image number k has been changed (S17: YES), the CPU 31 returns to S16 and updates the design image on the display panel 82, 92 to the design image of the changed image number k. If the user is satisfied with the design image displayed on the display panel 82, 92, he or she presses the decision button. If the decision button has been pressed (S18: YES), the CPU 31 ends this process. As a result, the design image selected by the user is held on the display panel 82, 92 without consuming power.

The display control process will be described with reference to Figures 8 to 10. This process updates the display of the design image on the display panels 82 and 92 when the power to the burner 1 is turned on and off. For example, when a user presses the operation knob 11 to cook on the right burner 4, the board switch 21 and the igniter switch 22 are turned on in that order. When the board switch 21 is turned on, the power supply circuit 35 supplies power to various circuits based on a signal from the switch input circuit 36, and the power to the burner 1 is turned on. This triggers the CPU 31 of the control circuit 30 to read the display control program from the ROM 32 and execute this process. When the igniter switch 22 is turned on, the CPU 31 activates the igniter 51 based on the input signal from the switch input circuit 36, and the right burner 4 is ignited by the ignition electrode. The right burner 4 enters a burning state.

The CPU 31 references the mode number stored in the flash memory 34 and determines whether the currently set design mode is the specified order mode (S21) or the random mode (S22). If the selection mode is set (S21: NO, S22: NO), the design image already displayed on the display panels 82, 92 is not updated, and the CPU 31 simply ends this process.

If the specified order mode is set (S21: YES), the CPU 31 executes the specified order display process (S23). If the random mode is set (S21: NO, S22: YES), the CPU 31 executes the random display process (S24). After the specified order display process or the random display process is completed, the CPU 31 ends this process.

The designated order display process will be described with reference to FIG. 9. As described below, the flash memory 34 stores the display number j of the design image scheduled for the next update. The CPU 31 reads the display number j of the design image scheduled for the next update and the number of displayed images m from the flash memory 34 (S30). The CPU 31 reads the image data Pj of the display number j from the flash memory 34 (S31) and updates the display on the display panels 82, 92 (S32). This changes the exterior design of the stove 1 when the power is turned on. The CPU 31 adds 1 to the display number j (S33) and determines whether the display number j is greater than the number of displayed images m (S34).

If the display number j is equal to or less than the number of displayed images m (S34: NO), the CPU 31 determines whether the power has been turned off (S36). If the display number j is greater than the number of displayed images m (S34: YES), the CPU 31 initializes the display number j to 1 (S35) and then determines whether the power has been turned off (S36). A power-off state means that all of the burners 4 to 6 and the grill burner are turned off. If the power has not been turned off (S36: NO), the CPU 31 returns to S36 and waits until the power is turned off.

When the power is turned off (S36: YES), the CPU 31 reads the image data Pj for the display number j (S37) and updates the display on the display panels 82, 92 (S38). This allows the exterior design of the stove 1 to change even when the power is off. The CPU 31 adds 1 to the display number j (S39) and determines whether the display number j is greater than the number of displayed images m (S40).

If the display number j is equal to or less than the number of displayed images m (S40: NO), the CPU 31 stores the display number j in the flash memory 34 as the display number j of the design image scheduled for the next update (S42). On the other hand, if the display number j is greater than the number of displayed images m (S40: YES), the CPU 31 initializes the display number j to 1 (S41) and stores the display number j in the flash memory 34 as the display number j of the design image scheduled for the next update (S42). Since the CPU 31 has ended the designated order display process, it returns to the display control process of FIG. 8 and ends this process.

In this manner, in the specified order mode, the design images displayed on the display panels 82, 92 are updated to a preset display order each time the stove 1 is turned on and off. The user can specify the display order and the design images to be displayed, so the exterior design of the stove 1 can be easily changed to suit the user's preferences. In addition, because the timing for updating the design images is set to when the power is turned on and off, the exterior design of the stove 1 can be changed when the user operates it. This allows the stove 1 to reliably notify the user that the exterior design has been changed.

The random display process will be described with reference to FIG. 10. The CPU 31 randomly extracts design images from those registered in the image data table 341 in the flash memory 34, and reads the corresponding image data (S51). Note that the method of random extraction is not limited, and for example, extraction may be performed using random numbers. The CPU 31 updates the display of the design image on the display panels 82, 92 based on the read image data (S52).

The CPU 31 determines whether the power has been turned off (S53). If the power has not been turned off (S53: NO), the CPU 31 returns to S53 and waits until the power has been turned off. If the power has been turned off (S53: YES), the CPU 31 again randomly selects design images from those registered in the image data table 341 and reads the corresponding image data (S54). The CPU 31 updates the display of the design images on the display panels 82, 92 based on the read image data (S55). Having ended the random display process, the CPU 31 returns to the display control process of FIG. 8 and ends this process.

In this way, in random mode, the design image displayed on the display panels 82, 92 is updated randomly each time the power to the stove 1 is turned on and off. This makes it impossible for the user to predict which design image will be updated next, which makes an impact on the user depending on the type of design image, and creates a sense of anticipation for the next updated design image.

As described above, the stove 1 of this embodiment is battery-powered and has a top plate 3 on the top of the housing 2. The stove 1 has display panels 82, 92 on the front of the housing 2. The display panels 82, 92 are made of electronic paper that can hold display content and can be updated electrically, and can display design images. The CPU 31 of the control circuit 30 of the stove 1 displays and updates the design image on the display panels 82, 92. This allows the exterior design of the stove 1 to be easily changed. Since the exterior design of the stove 1 can be changed simply by displaying a design image on the display panels 82, 92, there is no need to replace decorative panels with different designs as in the past, and the cost of preparing them is also unnecessary. In addition, since the display panels 82, 92 are made of electronic paper, the design image can be held on the display panels 82, 92 without consuming power even when the stove 1 is not in use, so the exterior design of the stove 1 can be maintained.

In the above description, the short-range communication unit 56 shown in FIG. 5 is an example of the "receiving unit" of the present invention. The flash memory 34 is an example of the "storage unit" of the present invention. The CPU 31 that executes the processes of S17 and S18 in FIG. 7 is an example of the "selecting unit" of the present invention.

The present invention is not limited to the above embodiment, and various modifications are possible. The stove 1 is a built-in stove, but it may be a table stove. The stove 1 has a grill device inside the housing 2, but it may be a stove without a grill device.

In the above embodiment of the stove 1, the display panels 82, 92 are provided in the lower half of each of the right panel portion 8 and the left panel portion 9 on the front of the housing 2, but they may also be provided on the upper panels 81, 91, or across the front of each of the right panel portion 8 and the left panel portion 9. They may also be provided on the front of the grill door 10.

The display panel may also be provided in a location other than the front of the housing 2, preferably in a location that is easily visible to the user. For example, as in the stove 100 shown in FIG. 11, in addition to the display panels 82, 92 on the front of the housing 2, a display panel 301 may be provided on the top surface of the top plate 300. In this case, the front and top surfaces of the stove 100 are covered with the display panels 82, 92, 301, making the exterior design of the stove 100 more impressive. Also, in FIG. 11, the display panels 82, 92 on the front of the housing 2 may be omitted, leaving only the display panel 301 on the top surface of the top plate 300.

In the stove 1 of the above embodiment, the same design image is displayed on the display panels 82 and 92, but different design images may be displayed. Furthermore, in addition to the examples given in the above embodiment, the design image may simply be white or black.

In the above embodiment, the stove 1 receives image data from the smartphone 12 via Bluetooth using the short-range communication unit 56 and stores it in the flash memory 34, but the connection may be wireless or wired. Image data may also be received from a tablet terminal, PC terminal, or dedicated terminal other than the smartphone 12.

In the stove 1 of the above embodiment, the design image displayed on the display panel 82, 92 is updated when the power is turned on and off, but it may be updated at other times. For example, the design image may be updated at predetermined intervals while the power is on.
