Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heating and cooling device for foods, and more particularly to a heating and cooling device used in vehicles such as cars and yachts.

BACKGROUND OF THE INVENTION Hitherto, there have been few proposals regarding this type of heating and cooling device. In other words, having contradictory heating and cooling effects will result in an unnecessarily high power consumption of the device, and in vehicles such as cars and yachts, the usable power will be greatly limited. ,
It has been difficult to create a device that has both contradictory effects.

Figures 7a, b, and c show conventional individual heating devices and cooling devices used in so-called recreational vehicles such as campers. It is a modified version, and the electrical circuit is the same as for general household use. FIG. 1A is a front view of a microwave oven 1 as a heating device and a refrigerator 2 as a cooling device. 1i Microwave oven 1 and refrigerator 2 are each provided with outlets 3 and 4 that receive power from a commercial power source, and are each independently supplied with power from the commercial power source. The same figure (b) and (C) are
They are electric circuit diagrams of a microwave oven 1 and a refrigerator 2, respectively.

In FIG. 6B, the microwave oven 1 receives power from a power source 5, which is a commercial power source installed at a campsite or the like or an AC power source generated by an engine 5a, by turning on a switch 6, and receives power from a power source 5 by turning on a switch 6, and by commands from a control device 7. A magnetron 9 driven by a booster circuit 8 is oscillated to dielectrically heat food or the like. On the other hand, the refrigerator 2 is configured to receive electric power from a power source 5 by turning on a switch 1O, and to drive a compressor 13 by a drive circuit 12 according to a command from a control device 11, as shown in FIG.

In this way, in the past, heating devices and cooling devices were used as independent devices, so their power consumption was completely independent of each other, and the instantaneous value of power consumption was the sum of the maximum ratings of both devices. I had no choice but to do it. For this reason, it is difficult for the refrigerator 2 as a cooling device to have a rapid cooling function using a large amount of electric power even for a short time, and for example, it is not possible to provide a cooling cooking function by rapid cooling. .

In particular, when the power source 5 is obtained from a generator driven by an engine 5a or the like as shown in the figure, the maximum available power is greatly limited, so the maximum power consumption of both heating and cooling devices is large. (It was restricted.

However, it has not been possible to realize a heating/cooling device that can effectively heat or cool down to the maximum allowable power of a power source such as a power generating means or a battery. In other words, it is configured so that heating power can be used up to the maximum allowable limit of the vehicle's power supply as needed, and conversely, cooling power can be used up to the maximum limit, making it possible to achieve extremely excellent and convenient heating and cooling.

This is what activates the cooling device.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a heating and cooling device showing one embodiment of the present invention.

In the figure, the energy source 20 is a generator driven by an engine or the like, a solar power generator, a battery, or the like. The power supply section 21 receives power from the energy source 20 and supplies power to the first and second power circuits 22 and 23. The output of the first power circuit 22 is supplied to a booster 24 to supply high voltage power to a magnetron 25. Therefore, the magnetron 25 oscillates and sends heating radio waves to the oven 2.
Supply to 6. On the other hand, the output of the 21st it power circuit 23 is
It is configured to drive the cooling means 28 that is supplied to the cooling power supply section 27.

Therefore, the cooling chamber 29 is cooled by the cooling means 28, and the uncooled objects inside are cooled.

Here, the power control unit 30 controls the first and the twenty-first! i power circuit 2
2.23, and the total power consumption is controlled to be below a predetermined value. That is, the power control unit 30 controls the amount of heat for heating or cooling the non-processed items such as cooked food to a desired value, and also controls the first and second power circuits so that the total power consumption is maintained at the maximum allowable value. It controls the operating state of 22 and 23. Therefore, if we take the case of a car as an example, if only cooling or heating is performed, each will require electricity that matches the power generation capacity of the car's generator (for example, the power generation capacity is 12V, 1V, 1V, etc.).
00A, it is possible to perform processing at approximately 1.2kW), and when performing heating and cooling processing at the same time, the first and second power circuits 22 and 23 can be The operating state is controlled and the maximum power consumption is maintained at 1.2 kW or less while appropriately distributing heating power to 800 W and cooling power to 400 W, for example.

Therefore, we have realized a heating and cooling device that can perform heating and cooling using any power while keeping the power below the maximum allowable power, which was difficult in the past, and freeing up the contradictory processes of heating and cooling. Moreover, it is extremely easy to use and can be used in places where commercial power is not available, and without installing a new alternator in the vehicle.It is also possible to combine processing with four-speed cooling and heating, which was difficult to do in the past. It is possible to provide a heating and cooling device for a vehicle that can be easily performed. In particular, by applying it to cooking equipment, it becomes possible to combine cooking with cooling and heating, which was difficult with conventional refrigerators that only had a cooling storage function. It is possible to achieve excellent thawing performance by combining heating and cooling, or to automate vegetable cooking etc. by combining heating and cooling, and is extremely user-friendly and can be used in any place with any movement. A cooking device can be realized.

FIG. 2 is a sectional view showing the structure of a heating and cooling device according to an embodiment of the present invention. In the figure, the same reference numerals as in FIG. 1 indicate corresponding components.

The oven 26 and the cooling chamber 29 are configured in the same housing,
It has a dual-purpose structure, realizing a heating and cooling cooking device. That is, the uncooked items (unprocessed items) 3 in the oven 26
1 is an evaporator 3 in which the refrigerant of a compressor 28, which is a radio wave heating and cooling means by a magnetron 25, circulates;
It is configured such that it can receive forced cooling by cooling air from a fan 33 that exchanges heat with 2. 34 is an expansion valve, 35 is a condenser, and 36 is a heat exchange fan for the condenser, which is configured to perform a refrigeration cycle together with the compressor 28. 37 is a cooling fan that cools the magnetron 25, the first and second power circuits 22, 23, and the like. Further, the cooling air from the fan 33 is sucked in from the air outlet 38 as shown by the arrow in the figure, and is drawn into the air inlet 38 of the oven 26.
Cool air is supplied from 9. The liquid is discharged from discharge ports 40 and 41. Further, the fan 36 takes in air through an inlet 42 and discharges air through an outlet 43 to exchange heat with the condenser 35 . Further, the fan 37 takes in air through an inlet 42, cools a magnetron, etc., and discharges the air through an outlet 41.

Note that 44 is a turntable, which can improve heating or cooling distribution.

With such a configuration, the power control unit 30 controls the operating states of the first and second power circuits 22, 23 according to the desired processing conditions of the non-processed items, and the power control unit 30 controls the operating states of the first and second power circuits 22, 23 in accordance with the desired processing conditions of the non-processed materials, and the power control unit 30 controls the operating states of the first and second power circuits 22, 23 so that the total power consumption thereof reaches a predetermined value. Each device is operated with a predetermined power distribution as shown below.

Further, FIG. 2(b) is an example of a control sequence that quickly cools the heated object to an appropriate temperature after cooking, and is effective in various reheating and cooking operations.

Furthermore, FIG. 2(c) is an example of a control sequence in which food is cooled and stored for an arbitrary period of time, then heated and cooked, and then cooled to an appropriate temperature. This control sequence is suitable for cooking that is delicate and requires a long time, such as automatically cooking at the specified time or cooking after fermentation. Of course, various control sequences other than this example are possible, and the total heating/cooling WI power is always kept below the predetermined power! 1! Therefore, it is possible to provide a heating/cooling cooking device that can save energy.

FIG. 4 is a sectional view showing another embodiment of the heating/cooling device of the present invention, and the same reference numerals as in FIG. 2 represent corresponding components, and detailed explanation thereof will be omitted. In the figure, fan 33
The cooling air supplied into the oven 26 is returned from the outlet 40b of the open 26 through the return path 45, and is sucked through the air supply port 46 and circulated. That is, the damper devices 47 and 48 are configured to be controlled to open and close at arbitrary timings by the power control section 30.

The state of the flow path to be evacuated can be selected.

Therefore, the damper 47, 48 can be adjusted arbitrarily and at any time as necessary to select the flow path of the air to be supplied to the object to be cooled, improve cooling efficiency, prevent the object to be cooled from drying, and reduce the amount of generated gas. Effects such as prevention of scattering can be obtained.

FIG. 5 is a circuit diagram of a heating and cooling device showing a more detailed embodiment of the present invention, and the same reference numerals as in FIG. 1 indicate corresponding components.

In the figure, the power supply section 21 is composed of switches 51, 52, inductors 53, 54, and a capacitor 60, which are controlled by a power control section 30 including a computer 50. The unidirectional power (smoothed DC power with large pulsations) of this power supply section 21 is transmitted to a first inverter (t-circuit) 22 consisting of a capacitor 55, 56, a transistor 57, a diode 58, and a control circuit 59, and a capacitor 61.
．． Transistor 62.63.64.65.66.67,
It is supplied to a second inverter circuit (2' is a power circuit) 23 consisting of diodes 68, 69, 70, 71, 72, 73 and a control circuit 74. The first inverter circuit is a so-called high frequency resonant inverter, and its operation is well known, so a description thereof will be omitted. The output of this high frequency inverter is supplied to the step-up transformer 75 of the step-up section 24, rectified by the capacitor 76 and diodes 77, 78, and supplied to the magnetron 25 with high DC voltage.
5 oscillates and radio waves are output.

On the other hand, the second inverter is a so-called three-phase bridge inverter, which converts the three-phase induction motor of the compressor 28 into P
It is driven by WM control.

Since the operation of this inverter is already well known, the explanation will be omitted.

The energy source 20 is a generator 20 driven by an engine.
It is composed of an a1 battery 20b and a diode 20c, and has a power supply capacity of, for example, 12V and 100A. Therefore, when the engine is driven at an appropriate rotation speed, it is possible to supply 1.2kW of power, and the power control unit 30 controls the maximum power consumption to be this 1.2k.
The configuration is such that control is performed so that the voltage is below W.

With such a configuration, the power control unit 30 controls the switching elements (transistors) of the two inverters 22 and 23.
The amount of power consumed can be adjusted extremely simply by controlling the power supply through the control circuit 59.74, and it is also possible to operate the power supply at the same time at an arbitrary power ratio, making it possible to control the heating and cooling power. This can be done arbitrarily and easily to maintain below the maximum allowable power.

FIG. 6 is a circuit diagram of a heating and cooling device showing another embodiment of the present invention, and the same reference numerals as those in FIG. 5 are corresponding components, and the explanation thereof will be omitted.

In the figure, 79 is an input current detector (input detector) that detects the current supplied from the energy source to the power supply unit 21, and the power control unit 30 reliably controls the maximum value of the input power to a predetermined value based on this signal. The fJ clause can be set below the value of
Moreover, the power consumption can be adjusted very easily by simply controlling the switching elements (transistors) of the two inverters 22 and 23 via the control circuits 59 and 74. This input detector 79 can be configured to detect input current as in this embodiment, or can be configured to detect input voltage. Since the terminal voltage changes depending on the magnitude of the supplied current, the supplied current (that is, the supplied power) can be detected by detecting this terminal voltage and based on the amount of variation. Therefore, the power control unit 30 can control the maximum value of input power to be reliably maintained at a predetermined value or less using the signal from the input detector that detects at least one of the input voltage and current.

In addition, the power consumption of the device as a whole can always be kept below the maximum allowable power. Therefore, it is possible to perform heating and cooling using arbitrary power below the maximum power allowed for heating and cooling, which has been difficult in the past, and enables heating and cooling processing that has not been previously possible due to riding behavior. In particular, by applying the present invention to a cooking device, it is possible to provide an excellent cooking device that is extremely easy to use and has functions such as defrosting, cooling cooking, and storage while riding.
