The following describes the implementation of the present disclosure with reference to the drawings.

Fig. 1 and Fig. 2 show the appearance of the heating cooker 1 of the present embodiment. Fig. 1 is a front perspective view of the heating cooker 1 with the door 7 closed. Fig. 2 is a front perspective view of the heating cooker 1 with the door 7 opened.

As shown in Fig. 1 and Fig. 2, the heating processor 1 comprises a housing 3, a heating chamber 5, and a door 7. The heating chamber 5 has an upper wall 5a, a side wall 5b, a side wall 5c, a rear wall 5d, and a bottom wall 5e, and is a space disposed in the housing 3. The door 7 covers an opening 3b disposed in a front frame 3a serving as the front face of the housing 3.

The heating chamber 5 has a microwave radiating port for radiating microwaves generated by a microwave oscillator such as a magnetron into the heating chamber 5. The microwaves radiated from the microwave radiating port heat objects such as food placed in the heating chamber 5.

A convection heater and a circulating fan, which are heat sources, are disposed between the rear wall 5d and the back plate of the heating chamber 5. An air intake port and an air exhaust port are disposed on the rear wall 5d of the heating chamber 5.

When the circulating fan is driven to rotate, the air in the heating chamber 5 is sucked from the air inlet, heated by the convection heater, and then sent back to the heating chamber 5 from the air outlet. In this way, the heated object is heated evenly. An air inlet is arranged at the front part below the bottom wall 5e, and the air inlet is used to introduce external air into the box body 3.

A water tank for storing water is arranged below the bottom wall 5e. The water is used to generate steam to be sent to the heating chamber 5. The water stored in the water tank is supplied to the steam generating unit (not shown) to become steam. The steam is supplied to the heating chamber 5 through a steam pipe connecting the steam generating unit and the heating chamber 5. A control unit (not shown) is arranged between the bottom wall 5e and the water tank. The control unit has electronic components such as a microcomputer that controls heating in the heating chamber 5.

The door 7 is pivotally supported on the housing 3 via a horizontal rotating shaft below the opening 3b. A handle 7a is mounted on the upper portion of the outer frame 13 of the door 7. When the user pulls the handle 7a to rotate the door 7 until the door 7 becomes horizontal, the front of the heating chamber 5 is opened. When the user pushes the handle 7a to rotate the door 7 until the door 7 becomes vertical, the front of the heating chamber 5 is locked.

A display unit 9 and an operation unit 11 are arranged on the right side of the front surface of the outer frame 13 of the door 7. The display unit 9 is a liquid crystal screen for displaying menus, etc. A communication device 40 for communicating with an external device is arranged inside the door 7. The display unit 9 also displays information such as recipes obtained from the external device through the communication device 40. The operation unit 11 is composed of buttons or dials, for example, and receives instructions from the user to the heating processor 1.

Fig. 3 is an exploded perspective view of the door 7. In Fig. 3, the front side and the rear side of the heating conditioner 1 correspond to the left side and the right side in Fig. 3, respectively.

As shown in Fig. 3, the door 7 includes, in order from the front: an outer frame 13, a fan case 19, a first metal plate 21, a second metal plate 23, a radio wave leakage prevention plate 25, and an inner frame 27. Behind the outer frame 13, a display unit 9, an operating unit 11, a base plate 15, and a fan 17 are arranged.

Electronic components such as a microcomputer for controlling the display unit 9 and the operation unit 11 are arranged on the substrate 15 .

The fan 17 sends out the external air introduced from the air inlets 14 and 49 to cool the electrical parts such as the substrate 15 and the communication device 40 which are heated from the heating chamber 5. The fan 17 is arranged in front of the radio wave leakage prevention plate 25. The communication device 40 is arranged adjacent to the fan 17. The communication device 40 communicates with the external device by any communication method. The communication device 40 communicates with the external device by, for example, a wireless LAN.

The fan housing 19 is disposed behind the outer frame 13 to cover the rear of the substrate 15 and the fan 17. A first air passage 29 is formed in the space between the fan housing 19 and the substrate 15 in front of the fan housing 19. The first air passage 29 is an air passage from the fan 17 to the substrate 15. That is, a portion of the fan housing 19 forms the first air passage 29.

A second air passage 31 is formed in the space between the fan housing 19 and the first metal plate 21 behind the fan housing 19. The second air passage 31 is an air passage from the fan 17 to the space between the communication device 40 and the radio wave leakage prevention plate 25. That is, another part of the fan housing 19 forms the second air passage 31.

The first metal plate 21 is disposed behind the base plate 15 with the fan housing 19 interposed therebetween, and insulates the heat from the heating chamber 5. The second metal plate 23 is disposed to cover the rear of the first metal plate 21, and insulates the heat from the heating chamber 5.

The radio wave leakage prevention plate 25 is a metal plate for preventing radio waves from leaking from the inside of the heating chamber 5 to the outside through the door 7. The radio wave leakage prevention plate 25 is installed on the rear side of the outer frame 13 to cover the rear side of the second metal plate 23. The inner frame 27 holds the radio wave leakage prevention plate 25 together with the outer frame 13.

Fig. 4 is a front perspective view of the heating conditioner 1 with the outer frame 13 of the door 7 removed. As shown in Fig. 4, the radio leakage prevention plate 25 is arranged on the outer side adjacent to the opening of the heating chamber 5. Therefore, when the inside of the heating chamber 5 is heated to a high temperature, the radio leakage prevention plate 25 also becomes high temperature.

As shown in FIG3 , the communication device 40 is located at the lower part of the outer frame 13, that is, near the lower part of the radio wave leakage prevention plate 25. Therefore, the heating conditioner 1 must be configured to isolate the radio wave leakage prevention plate 25 from the communication device 40 and cool the communication device 40. Even if the radio wave leakage prevention plate 25 becomes high temperature due to the heat inside the heating chamber 5, this configuration can still prevent the temperature of the communication device 40 from exceeding the operating temperature range.

Fig. 5 is a rear perspective view of a portion of the door 7 with the inner frame 27 and the radio wave leakage prevention plate 25 removed. As shown in Figs. 3 and 5, a second metal plate 23 is disposed on the left side of the outer frame 13. The second metal plate 23 is located behind the base plate 15 and is disposed between the heating chamber 5 and the first metal plate 21 in the front-rear direction.

Fig. 6 is a rear perspective view of a portion of the door 7 in a state where the second metal plate 23 is further removed from the state shown in Fig. 5. As shown in Fig. 3 and Fig. 6, the first metal plate 21 is located behind the base plate 15 and is disposed between the second metal plate 23 and the fan housing 19 in the front-rear direction.

Fig. 7 is a rear perspective view of a portion of the door 7 in a state where the first metal plate 21 is further removed from the state shown in Fig. 6. As shown in Fig. 3 and Fig. 7, the fan housing 19 is located behind the base plate 15 and is disposed between the base plate 15 and the first metal plate 21 in the front-rear direction.

The fan housing 19 has a fan storage portion 41 and a communication device storage portion 42 at its lower portion. The fan storage portion 41 and the communication device storage portion 42 store the fan 17 and the communication device 40 at the front side of the fan housing 19, respectively. An air inlet 49 for introducing external air is arranged at the lower portion of the fan storage portion 41.

The portion of the fan housing 19 located behind the fan 17 and the communication device 40 is a space separating the rear side of the fan 17 and the communication device 40, and a space between the fan housing 19 and the first metal plate 21. That is, a portion of the fan housing 19 functions as a second partition. In FIGS. 5 to 8 , the front side and the rear side of the heating conditioner 1 correspond to the far side and the near side in the figures, respectively. FIG. 8 will be described later.

Two through holes 19a arranged in the vertical direction are formed in the upper half of the fan housing 19. Each of the two through holes 19a is, for example, a long and narrow hole extending in the vertical direction. A cover 19c is arranged at the rear side of the through holes 19a, which is open on the left side in the front and back viewing angles.

The cover 19c changes the direction of the cooling air that flows through the through hole 19a from the front side to the rear side of the fan housing 19. As a result, the cooling air that has passed through the through hole 19a flows to the left along the rear side of the fan housing 19 when viewed from the back.

A through hole 43 serving as a first through hole is formed in the lower half of the fan housing 19. The through hole 43 is, for example, a triangular hole. A wall 44 is formed above the through hole 43 and protrudes rearward from the fan housing 19.

The wall 44 is a thin and long plate arranged at the rear of the fan housing 19 and extending in the horizontal direction. The wall 44 changes the direction of the cooling air that passes through the through hole 43 and flows from the front side to the rear side of the fan housing 19. As a result, the cooling air that has passed through the through hole 43 flows downward along the rear side of the fan housing 19.

On the left side of the lower part of the fan housing 19 when viewed from the back, a wall 19d is formed that protrudes backward from the fan housing 19. The wall 19d is a thin and long plate that is arranged at the rear of the fan housing 19 and extends in the vertical direction. The wall 19d changes the direction of the cooling air that flows from the cover 19c to the left when viewed from the back. As a result, the cooling air flows to the right when viewed from the back.

A through hole 19b that functions as a second through hole is formed in the upper portion of the fan housing 19. An exhaust port 45 is formed at the upper end of the fan housing 19. The cooling air that flows upward along the rear surface of the fan housing 19 returns to the front side of the fan housing 19 through the through hole 19b and is exhausted from the exhaust port 45.

Fig. 8 is a rear perspective view of a portion of the door 7 in a state where the fan housing 19 is further removed from the state shown in Fig. 7. As shown in Fig. 3 and Fig. 8, the base plate 15, the display unit 9, the fan 17, and the communication device 40 are located behind the outer frame 13 and are arranged between the outer frame 13 and the fan housing 19 in the front-rear direction.

The suction port 17a of the fan 17 faces the front-rear direction of the closed door 7. The discharge port 17b of the fan 17 faces the upper direction of the closed door 7. Therefore, the fan 17 sucks air in the front-rear direction of the closed door 7.

That is, the suction direction of the fan 17 is, for example, perpendicular to the direction in which the air inlet 49 of the fan housing 19 is directed. The fan 17 will discharge air in a direction that is, for example, perpendicular to the direction in which the fan 17 inhales air. Therefore, the rotation axis of the fan blades of the fan 17 will face the front-rear direction. For example, a sirocco fan can be used as the fan 17.

Fig. 9 is a front perspective view of the fan housing 19. Fig. 10 is a front perspective view of the fan housing 19 in a state where the fan 17 and the communication device 40 are stored in the fan housing 19. In Figs. 9 to 11, the front side and the rear side of the heating conditioner 1 correspond to the far side and the near side in the figures, respectively. Fig. 11 will be described later.

As shown in Fig. 9 and Fig. 10, the fan 17 is arranged adjacent to the communication device 40. The fan housing 19 has a partition wall 46 located between the fan 17 and the communication device 40 and formed on the rear surface of the fan housing 19. The partition wall 46 is formed integrally with the fan housing 19. The partition wall 46 functions as a first partition member separating the fan 17 from the communication device 40.

The air sent out from the fan 17 is introduced from the air inlet 49 disposed at the lower part of the fan housing 19. An exhaust port is disposed at the lower front part of the bottom wall 5e of the heating conditioner 1 to exhaust the air heated in the heating chamber 5 to the outside. Therefore, when the object to be heated is heated in the heating chamber 5, there is a possibility that the temperature of the outside air introduced from the air inlet 49 exceeds the operating temperature range allowed by the communication device 40.

The partition wall 46 prevents the air sent from the fan 17 from being directly blown onto the communication device 40. Thus, even if the temperature of the air sent from the fan 17 exceeds the permissible operating temperature range of the communication device 40, the communication device 40 can be prevented from being heated by the high-temperature air sent from the fan 17.

The partition wall 46 may partition the entire space between the fan storage portion 41 and the communication device storage portion 42, or may partition a portion of the space. For example, the partition wall 46 may also have a hole for passing wiring, which connects the fan 17 or the communication device 40 to the substrate 15 or the power circuit (not shown).

In front view, a wall 19e protruding forward is arranged at the left end of the fan housing 19. In front view, a wall 19g protruding forward is arranged parallel to the wall 19e on the left side above the fan storage portion 41 of the fan housing 19. A groove 19m is formed by the wall 19e and the wall 19g. A through hole 19a is arranged at the upper part of the groove 19m. A hole 19h is arranged in the wall 19g.

A connecting air passage 48 is formed between the opening of the upper portion of the fan housing portion 41 and the groove 19m by the wall 19e and the wall 47. The connecting air passage 48 has a through hole 43 disposed therein.

Fig. 11 is a diagram for explaining the air path formed in front of the fan housing 19. As shown in Fig. 11, the air introduced from the air inlet 49 is sent from the fan 17 to the connecting air path 48. In the connecting air path 48, a part of the air sent to the connecting air path 48 flows to the rear side of the fan housing 19 through the through hole 43. The remaining air flows upward in the groove 19m between the wall 19e and the wall 19g.

Part of the air flowing in the groove 19m flows from the hole 19h toward the substrate 15. That is, the first air passage 29 from the fan 17 to the substrate 15 includes: the connecting air passage 48, the lower part of the groove 19m, and the hole 19h. Through the first air passage 29, the external air sent from the fan 17 can cool the substrate 15. Thereby, the reliability of the operation of the substrate 15 can be improved.

The first air passage 29 is formed as a unidirectional air passage. Therefore, the pressure loss in the first air passage 29 can be reduced. The heated air flows in the first air passage 29 toward the exhaust port 45 disposed at the upper end of the fan housing 19. Thereby, the pressure loss can be further reduced. As a result, the air volume of the cooling air flowing in the first air passage 29 can be ensured, and the cooling efficiency of the substrate 15 can be improved.

The hole 19h is arranged above the communication device storage section 42. Therefore, when the air flowing from the hole 19h toward the base plate 15 is higher in temperature than the air in the space in front of the fan housing 19, it will not flow to the communication device storage section 42 but will rise to the base plate 15. In this way, the communication device 40 can be prevented from being heated by the high-temperature air.

In the hole 19h, the air that does not flow to the side of the substrate 15 will flow further upward in the groove 19m, and then flow to the rear side of the fan housing 19 from the through hole 19a.

Due to space saving, the groove 19m has a narrower width than the width of the opening of the fan 17. Therefore, a connecting air passage 48 is arranged between the groove 19m and the fan 17, and the connecting air passage 48 has a shape that is smoothly narrowed from the opening of the fan 17 toward the groove 19m. In the front view, a curved wall 19e is formed from the upper end of the wall on the left side of the fan storage part 41 to the right. In the front view, a flat wall 47 is formed from the upper end of the partition wall 46 on the right side of the fan storage part 41 to the left.

A connecting air passage 48 is formed by the wall 19e and the wall 47. The wall 47 is tilted so that the angle formed by the wall 47 and the partition wall 46 is larger than a right angle. This can prevent air from stagnating in the space between the fan 17 and the groove 19m. As a result, the air around the fan 17 can be prevented from becoming high in temperature, and the adjacent communication device 40 can be prevented from becoming high in temperature.

The through hole 43 is arranged along the wall 47 in the connecting air passage 48. The wall 47 is arranged obliquely as described above. Therefore, the through hole 43 has a triangular shape, and the aforementioned triangle has a side inclined along the wall 47. Thereby, the through hole 43 can be arranged in the connecting air passage 48 to effectively utilize the space. However, the through hole 43 can also have any shape.

FIG12 is a diagram for explaining the air path formed on the rear surface of the fan housing 19. As shown in FIG12, the air that has passed through the through hole 43 flows toward the communication device storage portion 42 through the wall 44. That is, the second air path 31 from the fan 17 to the space between the communication device 40 and the first metal plate 21 includes: the connecting air path 48, the through hole 43, and the wall 44.

Thus, the communication device 40 can be cooled indirectly by the external air sent from the fan 17 through the fan housing 19. As a result, the reliability of the operation of the communication device 40 can be improved.

By arranging the through hole 43 in the connecting air passage 48 above and adjacent to the fan 17, the cooling air can easily flow to the communication device storage section 42 arranged further below. Thus, the cooling efficiency of the communication device 40 can be improved.

The air that has passed through the through hole 43 flows upward from between the wall 44 and the wall 19d. The air that has passed through the through hole 19a flows in the third air passage 33, which is an air passage that passes through the space between the substrate 15 and the first metal plate 21. Thus, the substrate 15 can be cooled indirectly by the external air sent from the fan 17 through the fan housing 19. As a result, the reliability of the operation of the substrate 15 can be improved.

The air flowing upward along the rear surface of the fan housing 19 returns to the front side of the fan housing 19 through the through hole 19b and is exhausted from the exhaust port 45.

The cooling air that has passed through the air path to the rear of the fan housing 19 flows in the space between the rear of the fan housing 19 and the first metal plate 21. Thus, the first metal plate 21 can be cooled. At the same time, the cooling air forms an air curtain between the fan housing 19 and the first metal plate 21. Thus, the heat transfer to the fan housing 19 can be reduced.

Even if the air in the space between the first metal plate 21 and the fan housing 19 is heated by the heat of the first metal plate 21, the air can be quickly exhausted from the exhaust port 45 through the second air passage 31 and the third air passage 33. As a result, it is possible to suppress heat accumulation in the space between the first metal plate 21 and the fan housing 19, and improve the cooling efficiency of the substrate 15 and the communication device 40.

Fig. 13A to Fig. 13C are diagrams for explaining the air inlet 14 of the outer frame 13. Fig. 13A is a rear view of the outer frame 13, the fan housing 19, and the radio wave leakage prevention plate 25. Fig. 13B is a cross-sectional view along the line 13B-13B of Fig. 13A. Fig. 13C is a three-dimensional view of the cross section along the line 13B-13B of Fig. 13A.

As shown in FIG. 13A and FIG. 13B, as mentioned above, the air inlet 49 is arranged at the lower end of the fan housing 19. The air inlet 14 is arranged near the air inlet 49 on the lower surface of the outer frame 13. There is a possibility that high-temperature air that has been exhausted from the heating chamber 5 exists around the air inlet 14. In particular, the air from the rear side directly below the air inlet 14 closer to the heating chamber 5 may have a higher temperature than the air in front of the air inlet 14.

In this embodiment, a guide 50 is arranged around the air inlet 14 to guide the outside air to the air inlet 14. The guide 50 is formed to face the front side instead of directly below. Thus, the air closer to the room temperature existing in the front side of the air inlet 14 instead of directly below can be sucked from the air inlet 14.

As a result, the cooling efficiency of the cooling air can be improved. By not blowing high-temperature air, heating of electrical components such as the communication device 40 and the substrate 15 can be suppressed.

Fig. 14 is a rear perspective view of the outer frame 13 and the fan housing 19. As shown in Fig. 14, as mentioned above, an exhaust port 45 is disposed at the upper end of the fan housing 19. The air that has passed through the first air passage 29 on the front side of the fan housing 19 is directly exhausted from the exhaust port 45.

The air that has passed through the second air passage 31 and the third air passage 33 on the rear side of the fan housing 19 returns to the front side of the fan housing 19 from the through hole 19b. The air is exhausted from the exhaust port 45 together with the air that has passed through the first air passage 29. The upper part of the exhaust port 45 is covered by the frame 51. Therefore, even if moisture intrudes into the outer frame 13, the substrate 15 and the communication device 40 can still be protected from moisture.

FIG. 15 is an enlarged view of the periphery of the fan housing 41 of the fan housing 19. As shown in FIG. 15, the fan 17 has a fixing portion 54a and a fixing portion 54b. The fixing portions 54a and 54b have holes, and the aforementioned holes are holes for fixing the fan 17 with a latch for positioning when the fan 17 is installed in the fan housing 41. By inserting a latch formed in the outer frame 13 or the fan housing 19 into the hole, the fan 17 can be installed in the fan housing 41.

If the fan 17 is fixed only by the latch, there may be a case where the fan 17 vibrates and generates a sound when it is operated. In this embodiment, the pressing portion 53a and the pressing portion 53b are arranged on the fan housing 19. The pressing portion 53a and the pressing portion 53b press the fan 17 to the outer frame 13 near the fan storage portion 41 of the fan housing 19.

Screw holes 52a and 52b are arranged on both sides of the fan housing 19 and the outer frame 13. The screw holes 52a and 52b function as locking parts, and the locking parts are used to lock the fan housing 19 and the outer frame 13 near the pressing parts 53a and 53b.

After the fan 17 is fixed to the fan housing 41, screws are inserted into the screw holes 52a, 52b and tightened. In this way, the fan 17 can be pressed to the outer frame 13 with appropriate strength by the pressing parts 53a, 53b. As a result, when the fan 17 is in motion, the fan 17 and the fan housing 41 can be prevented from vibrating and generating vibration sound.

The pressing portions 53a, 53b or the screw holes 52a, 52b are disposed near the fixing portions 54a, 54b. The fixing portions 54a, 54b are components for fixing the fan 17 when the fan 17 is installed.

The fixing portions 54a and 54b have a strength assuming that a certain degree of pressure is applied in the vicinity thereof. Therefore, as long as the fan 17 is pressed against the outer frame 13 in the vicinity of the fixing portions 54a and 54b, the movement of the fan 17 can be suppressed without affecting the vibration of the fan 17.

The screw holes 52a and 52b have the same diameter as other screw holes 52c disposed at other positions of the fan housing 19. Thus, the types of screws used when assembling the fan housing 19 can be reduced, thereby reducing manufacturing costs.

According to this embodiment, a part of the fan 17 is arranged inside the radio wave leakage prevention plate 25. Thus, the height of the door 7 can be shortened, and the heating conditioner 1 can be miniaturized. By arranging the substrate 15 and the communication device 40 inside the door 7, a wide space can be ensured in the heating chamber 5, and the heating conditioner 1 can be miniaturized.

In this embodiment, a heating processor that heats the object to be heated using a microwave, a heater, or steam is described. However, the technology disclosed herein can be applied to any heating processor.
