Third, since hot heat is discharged to the front, the control panel mounted on the high heat passage flow path is exposed to the high heat and is exposed to the danger of not being operated normally (see FIG. 2 of Citation Document 1).

Fourth, there is a problem that does not implement the food as desired because the convection function is not implemented.

Fifth, since the heater is distributed in a number of places, there is a problem that it is difficult to configure the cooling system by heating the cavity in several places.

The present invention is proposed to improve all the above-mentioned problems, and proposes an oven capable of efficiently performing cooling of the oven by arranging a heating element appropriately.

In the structure described above, the upper heater 21, the magnetron 23, and the transformer 23 and the capacitor 25 are placed on the upper side of the cavity, that is, the upper support panel 10. The lower heater 22 is placed on the lower support panel 11. The convection heater 78 is located on the rear surface of the cavity 1. On the other hand, in some cases, all the heaters described above may be installed in a structure that is directly supported by the cavity 1, it is natural that each heater heats the inside of the cavity 1 at a predetermined position.

The front of the cavity (1) is provided with a door (2) for selectively opening the interior space of the cavity, and the control panel 12 is placed on the upper side of the door (2), the user to operate the oven A display is provided for displaying the operation button and the operating state of the oven.

The oven described above is provided with a flow path structure, in other words a cooling system, for causing the heat source of the oven and each component provided to the oven to be operated in thermal equilibrium in a steady state.

Hereinafter, the arrangement of the plurality of heaters placed in the oven will be described first, and then the flow path structure of air to be discharged to the outside after being generated by the heater and used for heating of the food will be described.

The upper heater 21, the magnetron 23, the transformer 24, and the capacitor 25 are parts that are placed on the upper side of the cavity 1 to generate high heat. The convection heater 78 is a component that is placed at the rear side of the cavity to generate high heat. The lower heater 22 is a component that is placed under the cavity to generate high heat.

Of the above-described heating elements, the upper heater 21, the magnetron 23, the transformer 24, and the capacitor 25 are placed on the rear surface of the cavity 1 to form a high heat generating portion. In order to prevent the heat of the high heat generating part from being transmitted to the control panel 12 in a manner such as radiation or convection, a first flow path guide 61 is provided as a blocking film between the control panel 12 and the high heat generating part. Lies. Although heat is generated in the control panel 12 even though the heat is weak, a concept corresponding to the high heat generating unit may be referred to as a low heat generating unit.

The convection heater 78 protrudes to a certain distance to the rear of the rear panel 4, and for this purpose, an opening 91 is formed at the rear of the rear panel 4. In addition, a convection cover 5 is provided at the rear of the rear panel 4 to cover the opening 91. The convection cover 5 can be seen in detail through the rear perspective view of the oven shown in FIG. 2, protruding rearward to the convection drive motor 72 through the opening 91, and the convection drive motor ( 72 is protected by the convection cover 5.

In order to allow the smoke or moisture inside the cavity 1 to be discharged to the outside, a cavity inlet duct 51 is placed on the side of the cavity 1. One end of the cavity inlet duct 51 is provided with its end open at an upper side of the cavity 1, and the other end thereof is open toward the inner space of the cavity 1. The cavity inlet duct 51 is provided with a damper driving motor 53 for controlling the opening and closing of the damper 52 and the damper 52.

3 shows the bottom portion of the cavity.

Referring to FIG. 3, a lower side of the cavity 1 is provided with a tray driving motor 71 for rotating the lower heater 22 and a tray (not shown) mounted inside the cavity 1. High heat is generated in the lower heater 22, and the high temperature of the lower heater 22 must not be transmitted to the tray driving motor 71 so that the tray driving motor 71 can be normally operated within a predetermined temperature range. have.

A cooling system with air for cooling the oven of the present invention as described above will be described with reference to FIGS.

First, an air inlet 41 through which air flows into an oven is formed on an upper side of the door 2, that is, an upper space corresponding to an upper space of the upper support panel 10 and an up and down direction. In the position of the space | interval between 12, it is provided long in the left-right direction of the said front panel 3. As shown in FIG. In addition, the discharge port 42 through which air is discharged to the outside of the oven is located at the lower space of the door 2, that is, at the position of the gap between the lower support panel 11 and the base panel 9. It is provided long in the left and right directions of the panel 3. As a result, the oven of the present invention takes a manner in which cold internal air flows into the upper space of the oven and then cools down to the lower side of the oven. Therefore, there is little possibility that the intake air and the discharge air are mixed with each other, and the operation efficiency of the cooling system is increased.

The air sucked through the suction port 41 is introduced into the high heat generating part through the first flow path guide 61 through the suction fan 31 placed directly behind the suction port 41. In addition, some of the air sucked through the suction port 41 does not flow into the high heat generating unit, and is directly moved to the lower space of the cavity 1 through the ventilation fan 32.

The air moved to the high heat generating portion by the suction fan 31 is circulated to a plurality of branches. In detail, the first flow path passes downward through the opening 91 formed in the rear panel 4 after passing through the high heat generating portion, and then cools the convection drive motor 72 and cools the cavity 1. After being moved downward, it is discharged to the outside through the discharge port 42. The second flow path passes through the high heat generating portion and is then sucked into the ventilation fan 32, moved downward through the left space of the cavity 1, and then cooled the lower heater 22, and then the discharge port 42. Is discharged through). After passing through the high heat generating portion, the third flow path moves downward of the cavity 1 through the right side of the cavity 1, and is then discharged to the outside through the discharge port 42. The third passage cools the heat generated from the electromagnetic heating source such as the magnetron 23, the transformer 24, the capacitor 25 and the like. In order to allow the high heat generated from the electromagnetic heating source to be cooled by the third flow path, the electromagnetic heating source is placed on the upper side of the cavity 1 to cool the cooling air discharged from the suction fan 31. Get it directly. The fourth flow path flows into the cavity inlet duct 51 before being discharged to the high heat generating portion, enters into the interior space of the cavity 1 through the right side of the cavity, and is discharged out of the cavity through the left side of the cavity 1. To the outside space. Of course, it is natural that the moisture and the smoke generated in the cavity 1 are discharged together on this path.

The circulation of air performed by the ventilation fan 32 will be described.

First, as described above, a part of the air sucked through the suction port 41 is sucked into the ventilation fan 32 to cool the tray driving motor 71, and then through the discharge port 42, as described above. It is discharged to the outside. The second flow path is discharged through the suction fan 31, and then a part of the air cooling the high heat generating part is sucked into the ventilation fan 32, and the sucked air is moved downward along the left side of the cavity and then the lower heater. The 22 is cooled and discharged to the outside.

In order to smoothly guide the air flow described above, the oven is provided with a plurality of flow path guides. First, a first flow path guide 61 is provided on the upper side of the oven to prevent the heat of the high heat generating portion from being applied to the control panel 12. The first flow path guide 61 not only prevents radiant heat and convective heat from the high heat generating unit from approaching the control panel 12 but also passes through the suction fan 31 to discharge the high heat generating unit. It serves to prevent the air to come back to the control panel 12. Since the influence of high heat by a plurality of parts placed on the high heat generating portion by the first flow path guide 61 is not applied to the control panel 12, the air cooling system operates smoothly even if the number of fans is small. You can get the advantages.

Since the first flow path guide 61 is provided as a blocking film, even if both the electromagnetic heating element and the radiant heating element are placed in the high heat generating portion behind the cavity, the heat generated in the high heat generating portion is in front of the cavity, in particular, It does not affect the low heat zone where the control panel is placed. Therefore, the parts of the low heat generating part including the control panel can obtain the advantage of operating stably. In addition, since some of the outside air used for cooling the low heat generating part is guided by the first flow path guide 61 and can stably flow directly into the front part of the ventilation fan 32, the ventilation fan Air discharged from (32) has the advantage that it can be cooled stably also other parts of the oven in the future that requires cold operating conditions.

In addition, in order to prevent the air once discharged from the ventilation fan 32 backflowing the upper space of the cavity 1, the upper space of the cavity 1 and the cavity (relative to the ventilation fan 32). A second flow path guide 62 for shielding the left space of 1) is formed.

In addition, a third flow path guide 63 is provided so that hot air discharged downward from the right side of the cavity 1 does not flow back into the space in which the control panel 12 is installed. The third flow path guide 63 may be in contact with the right side panel 8 and the lower support panel 11.

Meanwhile, referring to FIG. 3, in order to prevent the air transferred downward through the right side of the cavity from being mixed with the air transferred downward through the left space of the cavity, each flow path is separated. The fourth flow path guide 64 is formed. The air transferred downward through the ventilation fan 32 by the fourth flow path guide 64 is discharged to the outside without being transferred to the right side of the cavity, thereby leading to smooth air circulation.

In addition, the air transferred downward through the ventilation fan 32 is divided into two types of air. Specifically, relatively cold air conveyed through the front part of the ventilation fan 32 and relatively hot air conveyed through the rear part of the ventilation fan 32 are it. The cold air is sucked through the suction port 41, and then used only for cooling the control panel 12 itself, and the temperature thereof is relatively low. The hot air is sucked through the suction fan 31. Next, the air used to cool the high heat generating portion becomes relatively hot.

In this way, the air having different temperatures discharged by the same fan is used for cooling the different portions. Specifically, the hot air conveyed through the rear part of the ventilation fan 32 is used for cooling the lower heater 22 and then discharged to the outside. The cold air transferred through the front part of the ventilation fan 32 is discharged to the outside after cooling the tray driving motor 71. Here, the fifth flow path guide 65 is provided to prevent the hot air and the cold air from mixing with each other. Here, the hot air discharged from the ventilation fan 32 is used to cool the lower heater 22, and the cold air discharged from the ventilation fan 32 is used to cool the tray drive motor 71. Since the side heater 22 is essentially used in a hot atmosphere, it is a part that is not affected even if it is hot to some extent, whereas the tray drive motor 71 is essentially used in a cold atmosphere, and therefore it must be below a certain temperature. Because only Thus, in order to satisfy the operating conditions for each part, the flow path like the present invention is proposed.

Here, the fifth flow path guide 65 may extend from the lower side to the upper side of the cavity so as to completely divide the left space of the cavity 1 from the lower end to the upper end. In this way, it is possible to increase the reliability of the two types of air discharged from the ventilation fan 32 are not mixed with each other, and to cool the lower heater 22 and the tray drive motor 71. It has the advantage of keeping the nature of the original.

Hereinafter, with reference to the structural description described above, each cooling system implemented in the oven of the present invention will be described separately for each air flow structure.

4 is a view for explaining an air flow for cooling the high heat generating unit.

Referring to FIG. 4, the air sucked into the suction port 41 is first discharged to the rear of the first flow path guide 61 through the suction fan 31. The discharged air cools the upper heater 21, the transformer 24, the magnetron 23, and the capacitor 25. Then, the air warmed while cooling the heating element placed in the high heat generating portion is transported downward through the right space of the cavity 1, guided by the fourth flow path guide 64, and discharged through the discharge port 42.

On the other hand, since the air used for cooling the high heat generating unit is relatively hot, backflow should be prevented during the flow of the air. In order to prevent the backflow of air in detail, the first flow path guide 61 prevents the air flow back to the control panel 12 from the upper side of the cavity 1, and the third flow path guide 61. ) Prevents backflow of air to the control panel 12 from the right side of the cavity 1 and prevents mixing of air flow in the opposite direction from the lower side of the cavity 1 by the fourth flow path guide 64. Ensure smooth air flow.

5 is a view for explaining the flow of air flowing into the cavity.

Referring to FIG. 5, the air sucked into the suction port 41 is first discharged to the rear of the first flow path guide 61 through the suction fan 31. A part of the discharged air is sucked through the front opening (not shown) of the cavity inlet duct 51.

Here, the cavity inlet duct 51 is connected to the right side of the cavity 1 from the upper surface of the cavity. Therefore, the air discharged through the suction fan 31 eventually enters the inside of the cavity 1, and the introduced air is discharged through the left side of the cavity 1 together with the smoke and moisture inside the cavity 1. do. The discharged air is mixed with the air discharged by the ventilation fan 32 and discharged through the discharge port 42.

By the air flow as described above it can be obtained an advantage that the smoke and moisture in the cavity is easily discharged.

In addition, the cavity inlet duct 51 is provided with a damper driving motor 53 for automatically operating the damper 52 and the open state of the damper 52 by opening / closing. By such a configuration, the damper is opened in an operating state in which air should be introduced into the cavity, and the damper is closed in an operating state in which no air is introduced into the cavity. An operation state in which air should be introduced into the cavity may be, for example, a grill operation in which a lot of smoke is generated, and an operation state in which air should not be introduced into the cavity may be a steaming operation.

6 is a view for explaining the air flow for cooling the convection fan.

Referring to FIG. 6, a part of the air sucked into the suction port 41 is discharged to the rear of the first flow path guide 61 through the suction fan 31. A part of the discharged air is then straight ahead and flows into the opening 91. Here, the opening 91 is maintained in a closed state by the convection cover 5 while maintaining a predetermined space. Therefore, the air introduced into the opening 91 is transported downward while cooling the convection drive motor 72, and the air transported downward is mixed with the air transported downward through the ventilation fan 32 and then the Discharged through the discharge port 42.

It goes without saying that the temperature as the operating condition of the convection drive motor 72 can be accurately maintained by such an air circulation structure.

7 is a view illustrating an air flow for cooling the lower heater.

Referring to FIG. 7, the air sucked into the suction port 41 is first discharged to the rear of the first flow path guide 61 through the suction fan 31. The discharged air is used for cooling the high heat generating unit, and the cooled air is sucked to the rear of the ventilation fan 32 and transported downward along the left space of the cavity 1. At this time, the air transported downward does not flow back upward by the second flow path guide 62. The air transferred downward is guided to the lower heater 22 in the state guided by the fifth flow path guide 65 to cool the lower heater 22. The air cooled by the lower heater is discharged through the discharge port 42 in a state of being guided by the fourth flow path guide 64 and the fifth flow path guide 65.

8 is a view for explaining an air flow for cooling the control panel and the tray drive motor.

Referring to FIG. 8, some of the air sucked into the intake port 41 is sucked through the front part of the ventilation fan 32. Of course, the sucked air is in a state where the heat of the control panel 12 is absorbed. The air sucked through the front of the ventilation fan 32 is transferred downward through the left space of the cavity 1 and guided by the fifth flow path guide 65 to the tray driving motor 71. After that, it is guided by the fifth flow path guide 65 and discharged through the discharge port 42.

The overall air flow as described above is to ensure that each component is in thermal equilibrium within a range not exceeding the allowable temperature of each component. When the cooling system of the present invention is operated, each component is maintained until a constant temperature. It may, however, not reach to the extent that the part is allowed to exceed its allowable temperature.

According to one feature of the present embodiment, the suction fan 31 is disposed directly behind the control panel 12 in an elongated shape so that a large amount of air can be sucked quickly.

In addition, according to one feature of the present embodiment, in order to arrange the high heat generating portion entirely on the upper side of the cavity, so that the heat generated from the high heat generating portion is not transmitted to the front of the cavity in the form of radiation or convection, the The heat path of the high heat generating portion is shielded by the first flow path guide. Therefore, it is possible to cool a plurality of heat generating parts placed on the high heat generating portion in a more efficient state.

Of course, in the second embodiment, the first flow path guide 61 serves to suppress the transfer of the high heat generated in the high heat generating portion to the low heat generating portion. However, the suction fan provided in the first embodiment is not provided in the second embodiment, and in this embodiment, the first fan 99 is placed directly on the surface of the high heat generating portion.

When configured in this way, the air sucked through the first vent hole 95 and the second vent hole 98 formed on the surface of the first flow path guide 61 passes through the first fan 99. A function of cooling the convection motor and the like, which is guided to the rear, and a flow path guided to the right side of the cavity and a flow path guided into the cavity can be provided at the same time. In addition, since the air sucked through the first flow path guide 61 may be performed by the sound pressure formed by the ventilation fan 32, there is no big problem.

In addition, the fan provided in the second embodiment is different from the crossflow fan provided in the first embodiment as an axial fan. Thus, even if the axial fan is provided as a cooling fan, there is no problem in the implementation of the present invention.
