Description

The present invention relates to a cooker that heats a cookware placed on a top plate.

A cooking device having a flat top plate and heating a cooking container placed on the top plate by using a heating coil or a resistance heating heater as a heating source is known. As such a heating cooker, we also propose a device in which an operation unit that receives operation input from the user is configured by using a capacitance type switch arranged under the top plate, and the entire upper surface of the top plate is flattened. Has been done.

Here, when a cooking utensil such as a pot placed on a flat top plate is being heated, a liquid may be mixed between the cooking utensil and the top plate to form a water film, or by induced heating. When the cooking utensil floats, unintended movement of the cooking utensil may occur. Such movement of the cooking utensil is likely to occur when the combined weight of the cooking utensil and the cooking utensil inside the cooking utensil is light.

In addition, when the cooking utensil placed on the flat top plate is heated, the temperature of the cooking utensil rises, and at the same time, the temperature of the top plate with which the cooking utensil comes into contact also rises, which is equivalent to that of the cooking utensil and the top plate. It becomes the temperature of. In this state, if the cooking utensil is moved during or after cooking, the part of the top plate that was in contact with the high-temperature cooking utensil will be exposed. Various ideas have been proposed so as to allow the user to pay attention to such a high temperature part of the top plate.

For example, there has been proposed a cooking device in which a coating film is provided on the operation unit and the display unit arranged on the top plate to improve the visibility of the operation unit and the display unit (see, for example, Patent Document 1). ). The cooking utensil is further configured to have a coating film in an area other than the operation portion and the display portion of the top plate to reduce the slipperiness of the cooking utensil and the damage to the top plate.

Further, there has been proposed a heating cooker in which a portion of the top plate located above the heating coil is printed with a heat-resistant paint having a color or pattern different from that of other portions (see, for example, Patent Document 2). ..

In addition, a heating cooker that reduces the slipperiness of cooking utensils and improves the visibility of high-temperature parts of the top plate by alternately printing temperature-sensitive discoloration paint and anti-slip paint on the upper surface of the top plate. It has been proposed (see, for example, Patent Document 3).

JP-A-2009-24753 (Claim 1) Japanese Unexamined Patent Publication No. 2004-103445 (Page 6) JP-A-2009-243755 (Claim 1)

As the cooking device used by the elderly, there are increasing opportunities to select a cooking device that uses a heating coil or a resistance heating heater as a heating source. One of the reasons why such a cooker is preferred by users is that it does not use fire during cooking and that the top plate is flat and easy to clean.

However, elderly people tend to unknowingly pull the utensils placed on the top plate toward themselves during cooking. In addition, when the eyesight of the elderly is impaired, it is difficult to hold the cooking utensil in the optimum placement position on the top plate during cooking. When the cooking utensil placed on the top plate is moved, the positional relationship between the heating source and the cooking utensil changes, so that the cooking utensil cannot be heated efficiently.

According to the technique of Patent Document 1, the visibility of the operation unit and the display unit is improved. However, if the user, consciously or unconsciously, pushes or pulls the cookware placed on the top plate and applies a force to slide the cookware during cooking, the cookware can be easily prepared. Will move.

According to the technique of Patent Document 2, the visibility of the heating port on the top plate is improved. However, if a sliding force is applied to the cooking utensil placed on the heating port and the cooking utensil comes off from the heating port, the cooking utensil is easily moved.

According to the technique of Patent Document 3, the anti-slip paint is applied to the entire top plate to prevent the cooking utensil placed on the top plate from slipping. However, once a force sufficient to move the cooking utensil is applied, the cooking utensil may move to the outside of the heating port.

The present invention has been made against the background of the above-mentioned problems, and provides a cooking device capable of suppressing the movement of a user who slides a cooking utensil placed on a top plate.

The cooking utensil according to the present invention includes a top plate on which a cooking utensil is placed, and a heating source that is arranged below the top plate and is a heating coil or a resistance heating heater for heating the cooking utensil. The top plate is provided with a mounting portion indicating an area on which the cooking utensil is placed and a region in contact with the previously described placing portion, and the previously described placing portion in a state where the cooking utensil is in contact with the top plate. A resistance portion that generates a resistance force against the movement of the cooking utensil toward the outside is formed, and the resistance force of the resistance portion is stepwise or gradually outward from the outer periphery of the above-mentioned mounting portion. It is configured to grow continuously .

According to the present invention, the resistance portion becomes a resistance to the movement of the cooking utensil when it is added to the cooking utensil mounted on the mounting portion by sliding it toward the outside of the mounting portion. Therefore, it is possible to suppress the movement of the user who slides the cooking utensil placed on the top plate.

Here, the information regarding the operating state of the cooking cooker 1 includes the selected cooking mode, the progress of automatic cooking, the temperature of the cooking utensil mounted on the mounting unit 20, and the display of warning information.

FIG. 2 is a schematic configuration diagram of a main part of the cooking device 1 according to the first embodiment. FIG. 2 shows a schematic cross section and a functional configuration of the cooking utensil 1 together with the cooking utensil 300 mounted on the top plate 3. Although only one heating coil 4 is shown in FIG. 2, the structures related to the other heating coils 4 have the same structure. As shown in FIG. 2, inside the main body 2 of the cooking device 1, below the top plate 3, the heating coil 4, the coil base 9 supporting the heating coil 4, and the lower surface of the coil base 9 are located. A plurality of ferrite cores 10 to be arranged and an infrared sensor 11 are provided. A contact temperature sensor 12 is attached to the back surface of the top plate 3. Further, a temperature detection unit 13, a control unit 14, and an inverter 15 are provided.

The heating coil 4 is arranged below the mounting portion 20 provided on the top plate 3. The heating coil 4 is a coil configured by winding a conducting wire such as a copper wire or an aluminum wire, and generates a high frequency magnetic field by being supplied with a high frequency current. The heating coil 4 of the present embodiment has a double annular shape, but the shape and arrangement of the heating coil 4 are not limited to those shown in the figure. In addition, instead of the heating coil 4, a resistance heating heater may be provided as a heating source.

The coil base 9 is made of synthetic resin or the like, and accommodates and supports the heating coil 4.

The ferrite core 10 is a rod-shaped member made of a ferromagnetic material that is non-conductive and has high magnetic permeability. By providing the ferrite core 10, the downward leakage flux of the heating coil 4 is suppressed, the heating efficiency can be improved, and the heat of the cooking utensil 300 can be equalized. The shape and configuration of the ferrite core 10 do not limit the present invention.

The contact temperature sensor 12 is arranged in contact with the back surface of the top plate 3, that is, the surface facing the heating coil 4. A plurality of contact temperature sensors 12 may be provided for one heating coil 4. The contact temperature sensor 12 detects the temperature of the cooking utensil 300 placed on the top plate 3 via the top plate 3.

The infrared sensor 11 detects infrared energy radiated from the bottom of the cooking utensil 300 placed on the top plate 3 on the heating coil 4. The infrared sensor 11 is surrounded by a sensor case 110 so that the cooling air flowing in the vicinity of the heating coil 4 does not directly hit the infrared sensor 11. The infrared sensor 11 is held in the sensor case 110 while maintaining a spatial distance so that the ambient temperature around the infrared sensor 11 becomes uniform. The sensor case 110 is fixed to the coil base 9 with a tapping screw or the like, or is partially formed integrally with the coil base 9, so that the distance between the top plate 3 and the infrared sensor 11 is kept constant. I'm leaning.

A transmission window 16 is provided in the mounting portion 20 of the top plate 3. The transmission window 16 is provided so that the infrared sensor 11 can detect the infrared rays of the cooking utensil 300 transmitted through the top plate 3. The transmission window 16 is provided at a position within the range of the mounting portion 20 and facing the detection portion of the infrared sensor 11. It is desirable that the transmission window 16 is not painted so that infrared rays can easily pass through. However, if the transmission window 16 is not painted, the heating coil 4 and wiring inside the main body 2 may be visible from above the top plate 3, which is not desirable in terms of design. Therefore, when the transmission window 16 is not painted, the coil base 9 or the sensor case 110 holding the heating coil 4 may be provided with a cylinder or a plate toward the top plate 3. By providing such a cylinder or plate for blindfolding, it is possible to make the heating coil 4, wiring, etc. difficult to see from the outside. Further, instead of covering the entire surface of the transparent window 16 with paint, the transparent window 16 may be painted in a dot shape or a stripe shape to reduce the proportion of unpainted openings.

Further, the control unit 14 may be configured to have the function of the temperature detection unit 13.

(Structure of top plate)
FIG. 3 is a schematic plan view of the top plate 3 according to the first embodiment, and FIG. 4 is a schematic cross-sectional view of A1-A2 of FIG. In the present embodiment, the first resistance portion 31 and the second resistance portion 32 are provided on the outside of the mounting portion 20 on the upper surface of the top plate 3. For illustration purposes, in FIG. 3 and subsequent drawings, the first resistance section 31 and the second resistance section 32 are shown by hatching or shading.

The first resistance portion 31 has a shape surrounding the mounting portion 20, and is provided on the outside of the mounting portion 20 in contact with the mounting portion 20. The first resistance portion 31 in FIG. 3 is an annular shape similar to the outer circumference of the circular mounting portion 20. The second resistance portion 32 has a shape surrounding the first resistance portion 31 and is provided in contact with the outer periphery of the first resistance portion 31. In the example of FIG. 3, the second resistance portion 32 surrounds the entire three first resistance portions 31, and the entire portion of the upper surface of the top plate 3 excluding the mounting portion 20 and the first resistance portion 31 is formed. The second resistance portion 32. The second resistance unit 32 is also provided in an area overlapping the operation display unit 6. The first resistance portion 31 and the second resistance portion 32 generate resistance to the movement of the cooking utensil toward the outside of the mounting portion 20 in a state where the cooking utensil is in contact with the top plate 3. The magnitude of the resistance to the movement of the cooking utensil described above differs between the mounting portion 20, the first resistance portion 31, and the second resistance portion 32.

In the present embodiment, the surface of the top plate 3 is printed with a paint composed of a glass-based inorganic substance, a thermosetting resin, an ultraviolet curable resin, or the like, and the paint is used to print the resistance to the movement of the cooking utensil described above. To configure. The paint used for printing is not limited to the above, and a wide range of materials can be used as long as they have relatively high rigidity and low brittleness and do not contain harmful substances.

With reference to FIGS. 4A to 4C, a plurality of configuration examples of the mounting portion 20, the first resistance portion 31, and the second resistance portion 32 will be described. In the example shown in FIG. 4A, the paint 101 is provided on the upper surface of the top plate 3. The thickness of the paint 101 increases in the order of the mounting portion 20, the first resistance portion 31, and the second resistance portion 32. A step is formed at the boundary between the mounting portion 20, the first resistance portion 31, and the second resistance portion due to the difference in the thickness of the paint. Since the user can notice the movement of the cooking utensil by the impact when the cooking utensil is slid and hits the step, the movement of the cooking utensil to the outside of the mounting portion 20 is suppressed. The step between the first resistance portion 31 and the second resistance portion 32 may be larger than the step between the mounting portion 20 and the first resistance portion 31. By doing so, it is possible to further suppress the movement of the cooking utensil in the direction approaching the outer periphery of the top plate 3. Further, the paint 101 may not be provided on the mounting portion 20.

In the example shown in FIG. 4B, paints 101a, 101b, and 101c having different friction coefficients are provided on the mounting portion 20, the first resistance portion 31, and the second resistance portion 32 on the upper surface of the top plate 3. Has been done. Here, the coefficient of friction includes a coefficient of static friction and a coefficient of dynamic friction. When the user moves the cooking utensil placed on the top plate 3, the user feels the change in the frictional force caused by the paints having different friction coefficients, so that the user moves the cooking utensil. It becomes easier to recognize the state. The higher the coefficient of friction of the paint, the greater the resistance to the movement of the cooking utensil. Therefore, the paint 101a of the mounting portion 20, the paint 101b of the first resistance portion 31, and the paint 101c of the second resistance portion 32 are rubbed in this order. Increase the coefficient. By doing so, it is possible to further suppress the movement of the cooking utensil in the direction approaching the outer periphery of the top plate 3. Further, it is not necessary to provide the paint 101a on the mounting portion 20.

In the example shown in FIG. 4C, the placement density of the paint and the placement shape of the paint are different between the mounting portion 20, the first resistance portion 31, and the second resistance portion 32 on the upper surface of the top plate 3. ing. The higher the printing density of the paint, the greater the resistance to the movement of the cooking utensil. Therefore, the paint 101a of the mounting portion 20, the paint 101b of the first resistance portion 31, and the paint 101c of the second resistance portion 32 are printed in this order. The density is high. Further, the resistance to the movement of the cooking utensil is influenced not only by the printing density but also by the shape of the placed paint, particularly the shape of the upper surface of the paint. Even when the printing density is high, the resistance may be low and the cooking utensil may become slippery depending on the shape of the upper surface of the paint. Therefore, as shown in FIG. 4 (c), the paints are arranged in each of the mounting portion 20, the first resistance portion 31, and the second resistance portion 32 so that the resistance to the movement of the cooking utensil increases in this order. It constitutes the shape of the upper surface of 101a, 101b, 101c.

The configurations illustrated in FIGS. 4A, 4B, and 4C may be combined with each other. Further, it is not necessary to provide the second resistance portion 32. Further, instead of providing the first resistance portion 31 corresponding to each of the mounting portions 20, one first resistance portion 31 surrounding the plurality of mounting portions 20 may be provided.

As described above, in the present embodiment, the cooking utensil facing the outside of the mounting portion 20 in a state where the cooking utensil is in contact with the top plate 3 in the area in contact with the mounting portion 20 on which the cooking utensil is placed. A first resistance section 31 is provided to generate resistance to movement. According to the present embodiment, when a force for sliding the cooking utensil mounted on the mounting portion 20 is applied to the outside of the mounting portion 20, the first resistance portion 31 resists the movement of the cooking utensil. Will be. Therefore, the movement of the cooking utensil mounted on the mounting portion 20 to the outside of the mounting portion 20 is suppressed. For example, even if the user during cooking unintentionally pulls or pushes the cooking utensil to slide the cooking utensil, the resistance generated by the first resistance portion 31 causes the user to own the cooking utensil. Since the movement is easy to recognize, the movement of the cooking utensil can be stopped. Since the resistance to the movement of the cooking utensil can be recognized by the feeling obtained from the cooking utensil touched by the user, even the elderly or the visually impaired can easily recognize the movement of the cooking utensil. By suppressing the movement of the cooking utensil, it is possible to perform cooking while holding the cooking utensil in the mounting portion 20. By performing cooking while the cooking utensil is held in the mounting portion 20, uneven heating of the cooking utensil is reduced, the cooking finish is improved, and power consumption due to an increase in electric power that does not contribute to cooking is increased. Can be suppressed from increasing.

Further, by performing cooking while the cooking utensil is held in the mounting portion 20, it is possible to prevent the top plate 3 other than the mounting portion 20 from becoming hot due to the heat of the heated cooking utensil. .. Therefore, it is possible to reduce the chance that the user comes into contact with the hot top plate 3. Further, the opportunity that the operation display unit 6 arranged under the top plate 3 is exposed to a high temperature environment can be reduced, and the durability of the operation display unit 6 can be improved.

Further, the first resistance portion 31 provided on the outside of the mounting portion 20 generates a resistance force against the movement of the liquid spilled from the cooking container. Therefore, even if a spill occurs, the speed at which the spilled liquid spreads on the top plate 3 can be reduced, so that the expansion of the dirt range of the top plate 3 can be suppressed.

Further, as illustrated in FIG. 4A, when the thickness of the paint 101 of the mounting portion 20 is smaller than that of the first resistance portion 31 and the second resistance portion 32, the bottom surface and the top plate of the cooking utensil are used. The distance from the upper surface of 3 can be made relatively small. Therefore, the heating efficiency of the cooking utensil can be improved.

(Modification example)
Hereinafter, an example of modification of the arrangement or shape of the first resistance portion 31 and the second resistance portion 32 will be described with reference to the drawings.

FIG. 5 is a schematic plan view of the top plate 3 according to the first modification of the first embodiment. In the example shown in FIG. 5, the first resistance portion 31 and the second resistance portion 32 are not provided in the region of the top plate 3 that overlaps with the operation display unit 6 in a plan view. With such a configuration, the sensitivity of the touch panel type operation display unit 6 and the visibility of the display can be improved.

FIG. 6 is a schematic plan view of the top plate 3 according to the second modification of the first embodiment. In the example shown in FIG. 6, the first resistance portion 31 is provided in the region other than the mounting portion 20 of the top plate 3, and the second resistance portion 32 is not provided. With such a configuration, the manufacturing process of the top plate 3 can be reduced, and the productivity of the cooking device 1 can be improved.

FIG. 7 is a schematic plan view of the top plate 3 according to the modified example 3 of the first embodiment. In the example shown in FIG. 7, the first resistance portion 31 is provided on the entire left and right and rear of the mounting portion 20 and a part of the front side of the mounting portion 20 in the top plate 3. The second resistance portion 32 is provided in a region of the top plate 3 that overlaps with the operation display portion 6 in a plan view. The second resistance unit 32 in FIG. 7 is also provided in the area outside the operation display unit 6. The resistance to the movement of the cooking container of the first resistance portion 31 is larger than that of the second resistance portion 32. As described above, the second resistance portion 32, which has a larger resistance to the movement of the cooking container than the first resistance portion 31, is provided in the area overlapping with the operation display unit 6. With this configuration, it is possible to prevent the cooking container placed on the top plate 3 from being moved onto the second resistance portion 32, that is, onto the operation display portion 6. Therefore, it is possible to prevent the operation display unit 6, which is frequently contacted by the user, from becoming hot due to the heat of the heated cooking container.

8 (a) is a schematic plan view of the top plate 3 according to the modified example 4 of the first embodiment, and FIG. 8 (b) is a schematic cross-sectional view of B1-B2 of FIG. 8 (a). As shown in FIG. 8B, by making the thickness of the first resistance portion 31 larger than the thickness of the mounting portion 20 and the second resistance portion 32, the first resistance portion 31 is placed on the outer periphery of the mounting portion 20. A convex portion made of is formed. Here, the thickness of the first resistance portion 31 is the distance between the upper surface of the top plate 3 and the upper surface of the first resistance portion 31.

9 (a) is a schematic plan view of the top plate 3 according to the modified example 5 of the first embodiment, and FIG. 9 (b) is a schematic cross-sectional view of C1-C2 of FIG. 9 (a). As shown in FIG. 9B, by making the thickness of the first resistance portion 31 smaller than the thickness of the mounting portion 20 and the second resistance portion 32, the first resistance portion 31 is placed on the outer periphery of the mounting portion 20. A recess made of is formed. Here, the thickness of the first resistance portion 31 is the distance between the upper surface of the top plate 3 and the upper surface of the first resistance portion 31.

As shown in FIG. 8 of the modified example 4 and FIG. 9 of the modified example 5, the cooking container mounted on the top plate 3 is moved by providing a step between the mounting portion 20 and the first resistance portion 31. In addition, it becomes easier for the user to notice. For example, when the user moves the cooking container placed on the top plate 3, the entire bottom surface of the cooking container is not always in contact with the top plate 3, and the cooking container is tilted so that a part of the bottom surface is part of the top plate. There are also situations where we are in contact with 3. Even in such a situation, by providing a step between the first resistance portion 31 provided on the outer periphery of the mounting portion 20 and the first resistance portion 31, the impact of the cooking container when the step is overcome is transmitted to the user. It is possible to make it easier to notice the movement of the cooking container.

FIG. 10 is a schematic plan view of the top plate 3 according to the modified example 6 of the first embodiment. In the modified example 6, the first resistance portion 31 is provided on one side of the top plate 3 facing the user with the mounting portion 20 as a reference. Here, the side facing the user of the top plate 3 means the side that is planned to mainly face the user when the cooking cooker 1 is used. For example, it means the side where the operation unit or the display unit is provided, and the side where the grill or the storage door built in the main body 2 is provided. In the present embodiment, the first resistance portion 31 is provided on the front side of the top plate 3 provided with the operation display portion 6. The second resistance portion 32 is provided in the region behind the top plate 3 with respect to the mounting portion 20, that is, in the region opposite to the first resistance portion 31 in the depth direction. The resistance to the movement of the cooking container of the first resistance portion 31 is larger than that of the second resistance portion 32. With this configuration, it is possible to prevent the user who operates the cooking utensil from the front side of the top plate 3 from pulling the cooking container toward the front side and moving it.

FIG. 11 is a schematic plan view of the top plate 3 according to the modified example 7 of the first embodiment.
