[0021]
FIG. 1 is a configuration diagram of a heat treatment system 1 taking an IH cooking heater as an example of an induction heating type cooking device as a cooking device. The IH cooking heater 2 is mainly a heat source, and a 200 V power source is generally used to achieve a high thermal power. However, the application of the present invention may be a 100 V power source or other power sources. Further, it may be either single phase or three phase.
[0022]
These power supply specifications are the same for the components of the heat treatment system attached to the IH cooking heater 2.
[0023]

[0024]
In the main body of the IH cooking heater 2, at least an induction heating coil (hereinafter referred to as IH coil) 5 and an electronic component 52 constituting a control circuit are mounted as a heat generating component that generates heat due to heat loss, that is, a component to be cooled, The IH cooking heater 2 is built into the cabinet 6 of the system kitchen or is placed on it.
[0025]
In addition to the filter 7, the fan 8, and the fan motor 9 as a general range hood, the range hood 3 further includes a heat-dissipating heat exchanger 14 as a heat-dissipating part in the present invention.

(Exhaust), 30 is an armor door attached to the outdoor side of the exhaust port 11.
[0028]
Next, the structural example of the heat absorption part which takes heat from the heat-generating component in the IH cooking heater 2 will be described.
[0029]
FIG. 2 to FIG. 4 show an example of the structure of the coil heat absorption part 131 that takes heat from the IH coil 5 that is a heat generating component.
[0030]
FIG. 2 shows an example in which the coil heat absorbing portion 131 is attached to the upper surface of the IH coil 5, 22 is a top plate on which the pan 4 of the IH cooking heater 2 is placed, and 23 is a coil base that holds the IH coil 5. The coil heat absorption part 131 is preferably attached to the IH coil 5 with good adhesion, and is fixed via a heat conductive adhesive, grease or a thin sheet.
[0031]
FIG. 3 shows the internal structure of the coil heat absorption part 131. The base material 131a constituting the sealed container is most preferably made of a metal such as aluminum or copper having a good thermal conductivity, but the coil heat absorption part 131 is formed by induction heating. If there is a possibility that it itself generates heat, it may be made of a resin having good thermal conductivity. Moreover, you may utilize aluminum nitride, an alumina, etc. with very high heat conductivity.
[0032]
A partition plate 24 is provided inside the coil heat absorbing portion 131 to form a flow path for the liquid refrigerant 25, and the liquid refrigerant 25 that has flowed in from the inflow pipe 16 travels from the IH coil 5 by making a round in the base material 131a. The liquid refrigerant 25 that has absorbed heat and has risen in temperature flows out from the outflow pipe 15. Here, a plurality of protrusions may be provided in the middle of the flow path in the base material 131a, or a rib that divides the flow path into a plurality of paths may be provided to improve the heat transfer coefficient and the heat absorption performance.
[0033]
The liquid refrigerant 25 may be cooling water, but may be a highly insulating liquid or antifreeze liquid. Moreover, although tap water etc. are sufficient for cooling water, soft water, pure water, and water subjected to reforming treatment such as anticorrosion treatment are more preferable.
[0034]
FIG. 4 shows another embodiment, and the difference from FIG. 2 is an example in which the coil heat absorbing portion 131 is attached to the lower surface instead of the upper surface of the IH coil 5, and absorbs heat generated by the IH coil 5 via the coil base 23. Is the method.
[0035]
On the other hand, FIG. 5 and FIG. 6 show an example of the structure of the substrate heat absorbing portion 132 that takes heat of the electronic component 52 that is a heat generating component.
[0036]
FIG. 5 shows an example in which the substrate heat absorbing portion 132 is attached to the lower surface of the substrate 26 on which the electronic component 52 composed of a plurality of electronic components 52a and 52b is mounted. The substrate heat absorbing portion 132 corresponding to the size of the substrate 26 is provided. Yes.
[0037]
FIG. 6 shows the internal structure of the substrate heat absorbing portion 132, in which a plurality of partition plates 27 are provided to form the flow path 28 of the liquid refrigerant 25, and the liquid refrigerant 25 flowing in from the inflow pipe 16 is formed of the base material 132a. By making a round while meandering the inner flow path, heat is absorbed from the substrate 26 on which the electronic component 52 is mounted, and the liquid refrigerant 25 whose temperature has risen flows out from the outflow pipe 15. Here, the flow path 28 in the base material 132a may be branched into a plurality of paths instead of one path as shown in FIG.
[0038]
Next, a structural example of the heat-dissipating heat exchanger 14 that dissipates the heat taken away by the heat-absorbing part will be described.
[0039]
FIG. 7 shows an example in which the heat dissipating heat exchanger 14 is constituted by a cross fin tube type heat exchanger. The cross fin tube type heat exchanger 14 is composed of a plurality of thin heat dissipating fins 32 and a plurality of tubes 31 passing therethrough, and the liquid refrigerant enters the heat exchanger tube 31 from the outflow pipe 15 from the IH cooking heater 2. While circulating through the plurality of tubes 31, heat is radiated to the cooling air through the tubes 31 and the radiation fins 32, and the temperature is lowered.
[0040]
Here, the heat exchanger 14 for heat radiation is not the type as shown in FIG. 7, but may be a corrugated fin type having a plurality of meandering fins 32 as shown in FIG. Not specified.
[0041]
FIG. 9 is a block diagram showing the components of the heat treatment system 1 of the present invention, the flow of the liquid refrigerant 25 and the flow 19 of the cooling air, and the operation of the present invention will be described with reference to this figure and FIGS. 1 to 8 described above. To do.
[0042]
The heat generation amount (heat loss) of the IH coil 5 and the electronic component 52, which are heat generation components, depends on the thermal efficiency of the IH cooking heater 2, and in the heating of a magnetic material such as an iron pan, about 90% can be ensured. The amount of heat generated at that time is about 300 W. On the other hand, in the heating of non-magnetic materials such as aluminum and copper pans, the thermal efficiency is about 60 to 70%. For example, the amount of heat generated at the time of 3 kW electrical input is 1200 to 900 W. Further, since a plurality of IH coils 5 are mounted on the IH cooking heater 2 and a radiant heater and a roaster are also mounted on the IH cooking heater 2, the amount of heat generated by the IH cooking heater 2 as a whole is larger than expected. There is concern. For this reason, the IH cooking heater 2 requires more efficient cooling than before, and liquid cooling (water cooling) with cooling water or the like is strongly desired rather than air cooling.
[0043]
In the IH cooking heater 2, the heat absorbing parts 131 and 132 remove heat from the IH coil 5 and the electronic component 52 (the heat generating component is cooled), and the temperature of the liquid refrigerant rises. The heat radiating heat exchanger 14 in the hood 3 is reached. A pump 17 is provided in the middle of the outflow pipe 15, and the liquid refrigerant 25 is conveyed and circulated by driving the pump 17.
[0044]
In the range hood 3, a flow of cooling air (exhaust gas) 19 that is exhausted from the exhaust port 11 to the outside air via the filter 7, the heat exchanger 14, and the fan 8 is formed, and the liquid refrigerant 25 that has risen in temperature. Enters the heat exchanger 14 and is cooled by the cooling air 19 to reduce the temperature. Then, the liquid refrigerant 25 whose temperature has dropped is returned to the IH cooking heater 2 via the liquid storage tank 18 and the inflow pipe 16, and the liquid refrigerant 25 continuously circulates in the above circulation system.
[0045]
On the other hand, the temperature of the cooling air 19 supplied from the room rises in the heat exchanger 14 and is forcedly exhausted from the exhaust port 11 to the outside by the fan 8. The cooling air 19 supplied from the room may be air entering from other openings in the room (for example, doors, windows, and ventilation openings), but not shown in the range hood 3 or the adjacent wall except for the exhaust opening 11. An air supply port may be provided, and the cooling air 19 may be taken from the air supply port.
[0046]
Here, the liquid storage tank 18 functions as a tank for storing a spare refrigerant. The liquid storage tank 18 functions as one of the heat exchanger 14, the heat absorbing parts 131 and 132, and the piping systems 15 and 16. The liquid storage tank 18 may be omitted. Furthermore, the installation location of the liquid storage tank 18 and the pump 17 is not necessarily limited to the positions shown in FIGS. 1 and 9, and may be another location. In FIG. 9, reference numerals 42 denote electromagnetic flow rate adjustment valves, which most desirably control the flow rate of the liquid refrigerant 25 in accordance with the amount of heat generated by the IH coil 5 and the electronic component 52, which are heat generating components. If not necessary, the electromagnetic flow rate adjustment valve 42 may not be provided.
[0047]
Further, the pump 17 and the fan 8 of the present invention may be turned on / off according to the amount of heat generated by the IH cooking heater 2 (heat loss) or the type of pan to be heated, or may be set according to the amount of heat generated. You may drive by shifting.
[0048]
Furthermore, in the present invention, the installation interval in the height direction of the IH cooking heater 2 and the range hood 3 may be sufficiently separated, but may be close to each other. When the IH cooking heater 2 and the range hood 3 have substantially the same height direction, the range hood 3 may be installed on the back surface or the side surface of the IH cooking heater 2.
[0049]
Next, FIG. 10 shows another embodiment of the present invention and shows three parts of the range hood of FIG. As a new addition, there is an air opening / closing mechanism 29, which does not exhaust all the cooling air 19 whose temperature has been increased by the heat exchanger 14 from the exhaust port 11, but instead partially discharges a part 19b of the cooling air 19 whose temperature has been increased indoors. This method is used as an auxiliary heat source for indoor heating. This is particularly effective for winter heating. The air opening / closing mechanism 29 can be manually opened / closed, but it is preferable that the air opening / closing mechanism 29 is automatically opened / closed and the opening degree is adjusted in conjunction with an indoor air conditioning controller.
[0050]
11 and 12 show another embodiment of the present invention, which shows a part of the range hood 3 shown in FIG. These figures are examples of countermeasures when the cooling air 19 and indoor air are condensed in the heat exchanger 14 and its surroundings. In FIG. 11, the heat exchanger 14a is installed inclined in one direction. Is collected in the drain tray 55 along the inclination, and then drained.
[0051]
In FIG. 12, the heat exchanger 14 b is installed in a mountain shape in both directions, and condensed water is collected in both drain trays 55.
[0052]
FIG. 13 shows an embodiment in which the IH cooking heater 2, the range hood 3, the kitchen cabinet 6, and the like described above are integrated, and is commercialized and sold as a heat treatment system unit 53. At least, the range hood 3, the IH cooking heater 2, and the cabinet 6 are connected and integrated through the back wall 54 as shown in the figure.
[0053]
An operation panel 39 has a built-in controller that can control not only the IH cooking heater 2 but also the range hood 3. In addition, the heat treatment system unit 53 may be provided with a sink 37 and a storage case 40 in addition thereto.
[0054]
The embodiment of the present invention described above is a case where forced convection using the fan 8 is used for the heat exchanger 14 which is a heat radiating portion, and the heat taken away from the heat generating component is basically forced to be exhausted outdoors. The main feature is that the room temperature rise in the kitchen environment can be suppressed.
[0055]
On the other hand, FIG. 14 shows another embodiment of the present invention where natural convection and / or radiant heat transfer is used. To describe only the difference from FIG. 1, a heat radiating plate 20 is provided in place of the range hood 3. The heat radiating plate 20 radiates heat by natural convection 21 and radiant heat transfer of the indoor air flowing around it. It is cooled by absorbing the heat from the heat-generating component through the heat absorbing portions 131 and 132 and flowing the liquid refrigerant 25 whose temperature has risen.
[0056]
Here, the heat radiating plate 20 is attached so as to be attached to a partition wall such as a wall surface vertically provided in the vicinity of the IH cooking heater 2, but cooling by natural convection and radiant heat transfer is more effective than cooling by forced convection. Therefore, it is particularly suitable for cooling the IH cooking heater 2 with a small calorific value.
[0057]
FIG. 15 shows an example of the structure of the heat radiating plate 20, which is configured by attaching a heat radiating plate 34 having good thermal conductivity to a base material 20 a in which a pipe 31 through which the liquid refrigerant 25 flows is embedded or pasted. Here, the pipe 31 and the heat radiating plate 34 are fixed so as to increase the contact area so as not to hinder the transmission of heat, and in some cases, the pipe 31 may have a rectangular cross section. The material of the heat radiating plate 34 is preferably aluminum or copper, but may be stainless steel or the like in consideration of the surroundings. If the heat radiating plate 34 occupies a large area on the wall surface, the surface of the heat radiating plate 34 is preferred. You may draw photos, pictures and patterns.
[0058]
Here, the IH cooking heater 2 described with reference to FIG. 14 and the heat sink 20 and the kitchen cabinet 6 provided on a partition wall such as a wall vertically provided in the vicinity of the IH cooking heater 2 are integrated, and heat treatment is performed as shown in FIG. The system unit 53 may be commercialized and sold. At least the heat sink 20, the IH cooking heater 2, and the cabinet 6 provided on the rear wall surface are connected and integrated. In addition, a sink 37 and a storage case 40 may be provided.
[0059]
FIGS. 16 and 17 show another embodiment of the present invention, in which the liquid refrigerant 25 is tap water and is a passing type instead of a circulating type. A water supply pipe 36 is provided so as to branch from a part of the tap 35 of the tap water, and the water supply pipe 36 is connected to the IH coil 5 which is a heat generating component of the IH cooking heater 2 and the heat absorbing portions 131 and 132 of the electronic component 52. Then, the tap water whose temperature has risen due to the heat absorbed by the heat absorbing portions 131 and 132 is then drained as it is toward the drain outlet of the sink 37 through the water discharge pipe 38. Although the present embodiment has a simple configuration, since tap water is discarded, the flow rate is limited to some extent, and application to the IH cooking heater 2 with a small calorific value is more preferable.
[0060]
18 and 19 show another embodiment of the present invention, which is an example of an IH cooking heater 2 having a stand-alone cooling system using a liquid refrigerant, FIG. 18 is a configuration diagram of the IH cooking heater, and FIG. 19 is a perspective view thereof.
[0061]
The heat deprived from the heat absorbing parts 131 and 132 of the IH coil 5 and the electronic component 52, which are heat-generating components by the liquid refrigerant 25, is carried to the rear of the main body 2 by the liquid refrigerant by the pump 17 via the electromagnetic flow rate adjusting valve 42 and the piping system. Finally, the cooling air 19 taken in from the air supply holes 33 is finally exhausted from the exhaust holes 41 of the IH cooking heater 2 to the surrounding air by the fan 8 and the heat radiating heat exchanger 14 built in the rear of the main body 2. Is done. The heat-dissipating heat exchanger 14 used here may also be a heat exchanger of the type shown in FIG. 7 or FIG.
[0062]
In the figure, 12 is a roaster.
[0063]
Here, the exhaust hole 41 is provided with a throttle mechanism for suddenly changing the cross-sectional area of the cooling air 19, a stirring mechanism or a turbulent flow promoting mechanism, and the flow of the cooling air 19 flowing out from the exhaust hole 41 is vigorously mixed, stirred, It is possible to cause the cooling air 19 to generate a smooth ascending air flow by drifting and efficiently entraining air containing water vapor from the cooking pan. Examples of the throttle mechanism, the stirring mechanism, and the turbulence promoting mechanism include a cyclone and tornado generating mechanism, a stirring blade, and a reciprocating diaphragm. In this case, it is more preferable that a range hood or a ventilation fan is provided above the rising cooling air 19.
[0064]
In the methods shown in FIGS. 14, 15 and 18, 19, the liquid refrigerant 25 is not circulated by a forced circulation method using a pump or the like, but a heat pipe that does not have a drive source may be used. 9 and 17, the cooling of the IH coil 5, the cooling of the electronic component 52, and the cooling of the other heat generating components are performed in parallel. However, the cooling may be performed in series. A combination of parallel cooling and serial cooling may be used.
[0065]
Furthermore, the liquid refrigerant 25 of the present invention may be a sensible heat-based heat exchange system that remains liquid and does not change phase as described in the above embodiment, but latent heat-based heat exchange that changes phase from liquid to gas. It may be a method. In particular, more efficient cooling can be expected in the heat exchange system using latent heat.
[0066]
In the embodiment of the present invention, the example in which the IH coil 5, the electronic component 52, and the like, which are heat generating components in the IH cooking heater 2, are all cooled by a liquid cooling method (water cooling method) using a liquid refrigerant has been described. Only one of them may be a liquid cooling method and the other may be an air cooling method, that is, a so-called hybrid cooling method of liquid cooling and air cooling.
[0067]
Furthermore, the IH coil 5 and the electronic component 52 that are heat-generating components may each be a liquid cooling and air cooling hybrid cooling system. Moreover, the IH coil 5 and the electronic component 52 which are main heat generating components may be liquid-cooled, and other heat-generating components such as the roaster 12 and the radiant heater may be separated by air-cooling.
[0068]
In the above embodiment, the present invention has been described by way of example of an IH cooking heater which is a heating cooker equipped with an induction heating coil as a cooking device, but the present invention is a cooking device mainly using electricity, that is, a heating cooker, It is applicable if it has heat generating parts. For example, the present invention can be used for a jar rice cooker having an IH coil or the like, a single cooker such as a microwave oven having a heat generating part such as a magnetron, and a total heating cooker system in which these are combined or fused.
[0069]
In the above embodiment, the IH kicking heater 2 is linked with the range hood 3. However, when the heat generation amount of the IH kicking heater 2 is small, the range hood 3 is not operated. On the contrary, when the IH kicking heater 2 is stopped, only the range hood 3 may be operated as a ventilation fan.
[0070]
【The invention's effect】
According to the present invention, it is possible to cool a heat generating component of a heating cooker that generates heat due to heat loss by a liquid cooling method using a liquid refrigerant, which is more efficient than air cooling and further reduces the temperature rise of the heat generating component. it can.
[0071]
In addition, since the heat taken from the heat generating component by the liquid refrigerant is forcibly exhausted from the range hood to the outside, the rise in room temperature is suppressed and the kitchen environment can be maintained comfortably.
