Description

  The present invention relates to a heating cooker that takes measures against intrusion of cockroaches inside.

  As this type of cooking device, for example, in an induction cooking device, there are many holes in the outer case. This includes holes and gaps that are unavoidable in terms of configuration, such as those necessary for intake and exhaust, gaps between rotating parts and sliding parts, and gaps between fastening parts between parts. Cockroaches enter the interior through such small holes and gaps, and seek the dark, warm, and feedable area. There are many such places inside the cooker, but the place where cockroaches are most likely to collect is the vicinity of the control board where the ambient temperature is about 30 ° C, it is dark, narrow, and has a lot of adhesion of fat and the like due to inhalation of outside air . If cockroaches come into contact with the control board, the cooker may fail due to poor electrical continuity or short circuit. In particular, young cockroaches invade even from a small gap of only 0.5 mm, grow inside the cooker, lay eggs and multiply.

In order to prevent this, conventionally, a repellent is applied around the opening of the part to prevent the invasion of cockroaches inside the cooking device, and to prevent a conduction failure on the electric circuit due to the electrical board or dry cell. It is known (see, for example, Patent Document 1).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

( Reference form 1)
1 to 3 shows a heating cooker in accordance with a first reference of the present invention.

In the present reference, it illustrates an induction heating cooker incorporating a counter frame of the kitchen.

  As shown in FIG. 1, a heat-resistant tempered glass top plate 2 is provided on the outer case 1, and the pan is heated for cooking. A plurality of heating coils 3 as heating sources are provided under the top plate 2 so as to be pressed against the back side of the top plate 2 by springs. Below the heating coil 3, a plurality of control boards 4 incorporating a plurality of inverter circuits are installed on the right side through a partition plate, a roaster 5 is on the left side, an opening type operation unit 6 is on the right side, and an openable operation unit 6 is on the left side. A roaster 5 door is provided. The operation unit 6 is a rotary type, and an electric signal is sent to the control board 4 by operation of a heating power adjustment key or a timer key provided here, and the output of the heating coil 3 is controlled.

When the heating coil 3 is driven, the pan on the top plate 2 is heated, but the efficiency of the induction heating cooker is about 90%, and all the electric energy is not converted into the heat generated by the pan, and control is performed. Heat is also generated in the electronic components on the substrate 4 and the heating coil 3. These parts have a guaranteed heat resistance temperature, and must be used below that temperature. For this reason, a cooling device is required to cool these heat generating components.

  As shown in FIGS. 2 and 3, there is a cooling device including a fan 7, a motor 8, and a fan case 9 behind the control board 4, and sucks outside air from an air inlet 10 opened behind the top plate 2, The fan 7 cools the surroundings of the control board 4 and the roaster 5 and the heating coil 3, and is exhausted out of the outer case 1 through the exhaust port 11.

  Explaining a little now, the fan 7 is an axial flow type fan (sirocco fan), and is rotated by the motor 8 to generate wind. The fan 7 is of a double suction type, and is sucked from both the upper and lower directions of the rotating shaft and discharged in the circumferential direction of rotation. A fan case 9 having a casing structure is provided around the fan 7 in order to rectify the wind and efficiently generate the wind. The outlet of the fan case 9 is directed to the most heat-generating part of the control board 4. The air inlet 10 is provided behind the top plate 2. Since it is provided on the same surface as the top plate 2, there is a possibility that the user accidentally spills water on the top plate 2 and water enters from the air inlet 10. Even in such a case, only the air is sucked into the fan 7 after the intake path is once guided below the fan 7 so that the control board 4 is not exposed to water and the water falls down. ing.

  In the configuration as described above, the fan case 9 is divided into upper and lower portions with the partition plate supporting the motor 8 as a boundary. Among the fan cases 9, the fan case 9 in the upper part thereof is provided with repelling means 12 for imparting a repelling effect to the cooling air from the fan 7. The repelling means 12 is configured by applying a repellent to the fan case 9 or impregnating or kneading the repellent, and gradually evaporates in the air to spread the repellent effect around. If the repellent is applied to the inside of the fan case 9, the evaporated repellent rides on the cooling air and easily diffuses inside the cooker. If the repellent is applied to the outside, the fan 7 Even after stopping, transpiration is promoted by residual heat inside the cooker, and the repellent is easily diffused.

  With the above-described configuration, the repellent vaporized and evaporated from the fan case 9 is sent to every corner of the heating cooker by the cooling air, and the repellent effect is spread throughout the cooker and can be protected from cockroaches. In addition, by applying the repellent to the fan case 9 in the upper part, the repellent is flushed by a liquid such as water or oil that has entered from the air inlet 10, or the surface of the repellent is caused by a liquid such as water or oil. It will not be covered and will not interfere with the repellent transpiration. Further, the repelling effect is always obtained even after oil or the like adheres to the control board 4 as compared with the case where the repellent is applied to the surface or base of the control board only to prevent the control board 4 from contacting the circuit. Since new repellent ingredients are distributed, the repellent effect lasts long. In addition, since the repellent spreads throughout the cooking chamber, it is possible to prevent cockroaches from entering the cooking chamber. Therefore, it is also effective in terms of hygiene such as generation of odor due to feces and carcasses. In addition, since the repellent that has evaporated from the many gaps and holes in the outer case 1 leaks, the repellent effect is not only inside the cooker but also inside the counter frame of the system kitchen, that is, in the storage part installed under the cooker. Is obtained.

(Embodiment 1 )
4-6 shows the heating cooker in Embodiment 1 of this invention. The same elements as those of the reference form 1 are denoted by the same reference numerals and description thereof is omitted.

  As shown in the figure, the cooking device in the present embodiment is set such that the repelling means 12 is detachable in the intake path 13 passing through the vicinity of the motor 8.

Here, the air sucked from the air inlet 10 provided behind the top plate 2 once descends to the vicinity of the bottom surface of the cooker. Therefore, liquids such as water and oil that have entered from the air inlet 10 accumulate on the bottom surface of the outer case 1 and are not easily sucked by the fan 7. The fan 7 is sucked from both above and below, and is sucked also from the side where the motor 8 is supported. For this reason, the motor 8 can be cooled at the same time. The intake path 13 passing through the vicinity of the motor 8 is at a position that is considerably higher than the bottom surface of the outer case 1 and is higher than the fan 7, so that there is almost no suction of liquid and there is no influence on the repelling means 12.

  As shown in FIG. 5, the repelling means 12 in the middle of the intake path 13 is composed of a repellent 14 and a repellent case 15 containing the repellent 14. Further, the repellent case 15 is smaller than the air inlet 10 and can be attached to and detached from the fan case 9 which is an attachment part in the middle of the air intake path 13 by inserting a hand from the air inlet 10 as shown in FIG. Yes. That is, not the contractor but a general user can easily replace the repelling means 12.

  The repellent case 15 is made of resin, and a solid, gel-like or granular repellent 14 is set therein. The top and bottom of the repellent case 15 are configured so that the cooling air can pass therethrough, and the repellent agent 14 in the inside is also perforated or the cooling air is allowed to pass through the granular gaps. Thus, more transpirated repellent can be included in the cooling air. The repellent case 15 can be opened and closed, and if the repellent 14 in the transpiration evaporates and becomes less effective, it can always be refilled by checking the state of the repellent 14 inside. A repellent effect can be exhibited. Further, the effect can be obtained even by simply press-fitting the solid repellent 14 into the repellent case 15.

  With the above configuration, it is possible to prevent liquid such as water or oil from directly adhering to the repellent means 12, without obstructing the transpiration of the repellent, and to obtain a stable transpiration amount. A repellent effect can be obtained. Further, since the repellent 14 can be easily replaced if the repellent effect is weakened, the repellent effect can be maintained semipermanently. Moreover, since the repellent case 15 is opened and closed and can be replaced without directly touching the repellent 14, even those with weak skin can use it with peace of mind. In addition, since the repellent case 15 can be freely opened and closed, and only the repellent 14 contained therein can be exchanged, it is possible to reduce the price and rationalize it.

(Embodiment 2 )
FIG. 7 shows a cooking device according to Embodiment 2 of the present invention. The same elements as those of the reference form 1 are denoted by the same reference numerals and description thereof is omitted.

  As shown in the figure, the heating cooker in the present embodiment is provided with a re-intake path 16 for re-inhaling a part of the cooling air from the inside of the outer case 1 in addition to the intake path 13 by the fan 7. 16, repelling means 12 is provided.

  That is, the cooling air that has cooled the heating coil 3 and the like inside the cooker is re-inhaled near the top plate 2 of the fan case 9. Thereby, the evaporation of the repellent in the repellent means 12 is promoted by the warm air after the inside is cooled. However, since the flow rate of the re-intake passage 16 leads to an increase in the temperature of the cooling air, it is necessary to determine the flow rate within a range that can sufficiently satisfy the cooling performance inside the cooker.

  Thus, the cooling air discharged by the fan 7 cools the heat generating components on the control board 4 and then is sent upward to cool the heating coil 3. The cooling air sent to the left side of the cooking device cools the surroundings of the roaster 5. Thus, the cooling air which cooled each component in each part has temperature higher than external air, and is drying. By allowing the air after cooling to pass through the repelling means 12, the transpiration of the repellent is increased compared to when the outside air is allowed to pass. Further, the repelling means 12 has the same configuration as that of the second embodiment and the repellent case can be attached and detached to facilitate handling. In this embodiment, the repelling means 12 can be attached / detached as appropriate, for example, from a dedicated attachment / detachment opening, although not shown.

  With the configuration as described above, the transpiration amount of the repellent of the repellent means 12 can be increased, and the repellent effect inside the cooker can be enhanced. Further, the repelling means 12 is not affected by the intrusion of liquid such as water or oil from the air inlet 10.

  The state of the repellent means 12 can be easily and visually confirmed from the outside of the outer case 1 by making the portion of the top plate 2 covering the outer case 1 facing the repellent means 12 transparent. By doing in this way, it becomes easy to judge the replacement | exchange time of the repellent of the repelling means 12, and if a repellent effect becomes thin, it can respond immediately.

The configurations of the above-described reference modes 1 and 1 and 2 can be appropriately combined as necessary, and are not limited to the embodiments themselves.

  As described above, the heating cooker according to the present invention can continuously exert the repelling effect on the entire cooking device and can protect the entire cooking device from cockroaches, so the induction incorporated in the counter frame of the system kitchen The present invention is not limited to a heating cooker or a stationary induction heating cooker, and can be applied to any heating cooker having a fan.
