2. Description of the Related Art Conventionally, as a temperature / humidity adjusting device for adjusting an internal chamber such as a bread dough or a storage room for fresh vegetables to a desired low temperature (for example, 3 ° C.) and high humidity (for example, 90%), FIG.
A temperature and humidity adjusting device as shown in FIG.

FIG. 5 is a schematic configuration diagram showing an example of a conventional temperature and humidity adjusting device.

As shown in FIG. 5, this conventional temperature / humidity adjusting device has a blower 3, a cooling heat exchanger 4, a heating coil 5 and a humidifier 6 arranged in an adjusting chamber 2 in a housing 1.
And a cooling unit 7 for causing the cooling heat exchanger 4 to perform a cooling operation.
A temperature sensor 8, a humidity sensor 9, a control unit 10,
The operation unit 11 and the timer 12 are provided.

The housing 1 has an air inlet 13 on one side and an air outlet 14 on the other side. Each component arranged in the casing 1 and the adjustment chamber 2 inside the casing 1 is installed in a chamber (not shown) of a bread dough or fresh vegetable storage (not shown) which is a chamber to be adjusted whose temperature and humidity are to be adjusted. Is installed.

The blower 3 allows the air in the storage to flow into the adjusting chamber 2 through the air inlet 13, and the temperature in the adjusting chamber 2 is passed through the cooling heat exchanger 4, the heating coil 5 and the humidifier 6. And the humidity-controlled air is supplied from the air outlet 14 into the storage.

The cooling heat exchanger 4 includes a cooling pipe 4a and fins (not shown) thermally coupled to the cooling pipe 4a.
And a defrosting electric heating pipe 4b thermally coupled to the fins
Is a commercially available cooling coil with a defrost heater.

Although not shown in the drawing, the cooling unit 7 has a compressor, a condenser, an expansion valve and the like, and constitutes a refrigerator together with the cooling pipe 4a. Cooling pipe 4a
Acts as a refrigerant evaporator in the refrigerator.

Here, the reason for providing the heating coil 5 will be described. When controlling the cooling by the cooling pipe 4a, specifically, the compressor is controlled, but an inverter or the like which is expensive to continuously control the operation of the compressor to continuously control the cooling amount. The reason is that even if the operation of the compressor is controlled steplessly, the cooling amount cannot be continuously controlled from zero and can be continuously controlled only from a predetermined amount. In general, the compressor is controlled to be turned on and off, and the cooling amount is set to 10
On / off control of 0% and 0% is performed. The compressor cannot be frequently turned on and off due to restrictions such as a refrigeration cycle. For example, it cannot be turned off unless 5 minutes have passed since it was turned on, and 2 minutes have passed since it was turned off. It cannot be turned on. Therefore, if the temperature is adjusted only by the cooling heat exchanger 4, the temperature hunting becomes large, and the temperature cannot be adjusted with high accuracy. Not only that, when the temperature is adjusted only by the heat exchanger 4 for cooling, the temperature in the storage may be lower than the target temperature in a cold region in winter, but in this case, The temperature cannot be adjusted to the target temperature. Therefore, by heating the air supercooled by the cooling heat exchanger 4, the total heat output as a whole is continuously controlled from zero (that is, in the storage) without frequently turning on and off the compressor. Heating so that the temperature in the storage can be controlled with high accuracy) and the temperature in the storage can be adjusted to the target temperature even if the temperature in the storage is lower than the target temperature in the first place. The coil 5 is provided. Note that the heating amount of the heating coil 5 can be controlled by controlling the amount of electricity or the amount of time that the heating coil 5 is energized to the nichrome wire or the like. The quantity can be easily controlled continuously from zero by an inexpensive circuit or the like.

The temperature sensor 8 and the humidity sensor 9 are installed in the vicinity of the air outlet 14 or at an appropriate place in the storage, and detect the temperature and humidity at that place, respectively.

The control unit 10 includes, for example, a microcomputer, a blower 3, a heating coil 5, a humidifier 6,
The cooling unit 7 and the drive circuits corresponding to the defrosting electric heating pipe 4b are provided, and have a function as a temperature control unit, a function as a humidity control unit, a function as a defrost control unit, and the like. That is, when the start switch of the operation unit 11 is operated, the control unit 10 operates the blower 3, performs temperature control and humidity control, and also performs defrost control.

The temperature control will be described below.
Is based on the detection signal of the temperature sensor 8 so that the temperature in the storage is a desired temperature (a target temperature, which is set by the user by operating the operating unit 11). The heating coil 5 is controlled. Specifically, for example, the control unit 10 obtains a deviation (= target temperature-detected temperature), and the deviation is predetermined as shown in FIG.
When it is smaller than ΔT, the cooling unit 7 (specifically, the compressor) is turned off (that is, the cooling amount of the heat exchanger 4 is set to 0).
In addition, when the deviation is −ΔT or more, the cooling unit 7 (specifically, the compressor) is turned on (that is, the cooling amount of the heat exchanger 4 is set to 100%). Also,
As shown in FIG. 6B, the controller 10 continuously changes the total heat output, which is the sum of the cooling amount of the heat exchanger 4 and the heating amount of the heating coil 5, according to the deviation. Then, the heating coil 5 is controlled.

To explain the humidity control, the control unit 10 operates the operation unit 11 based on the detection signal of the humidity sensor 9 so that the humidity in the storage is the desired humidity (target humidity). The humidifier 6 is controlled so that

Further, the defrosting control will be described. The control section 10 is based on a timer signal from the timer 12 and
Whenever the defrosting time interval (for example, 6 hours) set by the user operating the operation unit 11 in advance elapses, the temperature control and the humidity control described above are stopped for a predetermined defrosting time (for example, 10 minutes). The defrosting of the fins of the heat exchanger 4 is performed by stopping the operation of the blower 3 and the cooling unit 7 and operating the defrosting electric heating pipe 4b with a heating amount of 100%, for example.

The reason for performing such defrosting is as follows. When the normal operation is continued, the moisture contained in the air that has flowed into the heat exchanger 4 by the blower 3 is cooled by the heat exchanger 4 and becomes frost to adhere to the fins, and the amount of adhesion increases. As a result, this frost hinders the air trying to pass through the heat exchanger 4 and deteriorates the cooling efficiency of the heat exchanger 4. Therefore, the defrosting of the fins is performed.

According to the temperature / humidity adjusting device shown in FIG. 5, the above-mentioned temperature control and humidity control are performed during normal operation,
The temperature and humidity inside the storage are adjusted to the desired temperature and humidity. On the other hand, at the time of defrosting, defrosting is performed by the above-described defrosting control.

[0017]

However, in the conventional temperature / humidity adjusting device described above, since the heating coil 5 is provided, the temperature of the chamber to be adjusted can be adjusted with high accuracy, but the heating coil 5 cannot be adjusted. The heat exchanger 4
Since it must be provided separately from the above, there is a drawback inevitably increasing the size and cost of the device.

Further, in the conventional temperature / humidity adjusting device, the defrosting electric heat pipe 4b is operated only during defrosting, and as described above, the fins of the heat exchanger 4 originally have a total heat output necessary for temperature control. Since it is supercooled, the rate of frost adhering to the fins is high. Therefore, the defrosting time interval must be relatively short. Therefore, during the defrosting time, the temperature of the adjustment target room is not adjusted, so the period in which the temperature of the adjustment target room is not adjusted increases.
Not preferred. In addition, since defrosting is frequently performed, operating costs such as electricity charges required for defrosting increase.

Under the circumstances as described above, the conventional temperature adjusting device, in which the humidifier 6 is omitted and the humidity is not adjusted in the conventional temperature and humidity adjusting device,
The same is true.

Further, in the above conventional temperature and humidity adjusting device,
Since the fins are supercooled as described above, the dehumidifying effect of air in the heat exchanger 4 is large, and therefore, a large amount of moisture in the air taken by the heat exchanger 4 must be supplemented by the humidifier 6. For this reason, the humidifier 6 having a large humidifying capacity must be used, and the cost is inevitably increased, and the water consumption in the humidifier 6 also increases.

The present invention has been made in view of the above circumstances, and the temperature of the chamber to be adjusted can be adjusted with high accuracy without specially providing a heating coil.
An object of the present invention is to provide a small-sized and inexpensive temperature adjusting device and temperature / humidity adjusting device that can extend the defrosting time interval.

It is another object of the present invention to provide a temperature / humidity adjusting device which can use a humidifier having a small humidifying capacity and consumes little water in the humidifier.

[0029]

In the present invention, the heating coil in the above-mentioned conventional temperature / humidity adjusting device is removed, and instead, the heating means corresponding to the defrosting electric heating pipe in the conventional temperature / humidity adjusting device is used for temperature adjustment. Controlled.
Therefore, according to the present invention, since there is no heating coil, it is smaller and less expensive than the conventional temperature / humidity adjusting device, and the temperature of the adjustment target chamber can be adjusted with high accuracy as in the conventional temperature / humidity adjusting device. Can be adjusted.

Further, in the present invention, since the heating means which is thermally coupled to the fin which is thermally coupled to the cooling pipe of the heat exchanger is controlled for the temperature adjustment, the fin itself is originally the temperature adjustment. Only the level corresponding to the total heat output required for the fins is cooled, and the fins are not overcooled. Therefore, according to the present invention, the adhesion speed of the frost adhering to the fin is slower than that of the conventional temperature and humidity adjusting device, and the defrosting time interval can be lengthened. Therefore, the period during which the temperature of the adjustment target chamber is not adjusted is shorter than that of the conventional temperature and humidity adjusting device, which is preferable. Moreover, since defrosting is not performed as frequently as in the conventional temperature and humidity adjusting device, the operating cost such as an electric charge required for defrosting is reduced.

Further, in the temperature / humidity adjusting apparatus according to the present invention, since the fins are not overcooled as described above, the dehumidifying effect of air in the heat exchanger is small, so that the moisture in the air taken by the heat exchanger is small. Since the amount of water that has to be supplemented by the humidifier is small, the amount of water that needs to be supplemented by the humidifier can be small, so that it is possible to use a humidifier having a small humidifying capacity, which can reduce the cost and consume water in the humidifier.

The evaporated refrigerant vapor is sucked into the compressor 51, compressed, and discharged as a high-pressure, high-temperature gas. Most of the lubricating oil of the compressor 51 contained in the discharged gas is separated by the oil separator 52, the refrigerant vapor enters the condenser 53, is cooled and liquefied, and is received in the state of high-pressure liquid in the receiver. It is temporarily stored in 54. Next, the pressure of this refrigerant decreases via the refrigerant expansion valve 55,
Returning to the cooling pipe 41 as an evaporator, the above operation is repeated.

Referring again to FIG. 1, as the humidifier 25, any humidifier such as a steam humidifier or an ultrasonic humidifier can be adopted. In the present embodiment, the humidifier 25 is arranged in the adjustment chamber 22, but the humidifier 25 itself is arranged in another place so that the steam or spray from the humidifier 25 is adjusted to the adjustment chamber 2.
You may lead into 2.

The temperature sensor 27 and the humidity sensor 28 are installed in the vicinity of the air outlet 33 or at an appropriate place in the storage, and detect the temperature and the humidity at that place, respectively.

That is, when the start switch of the operation unit 30 is operated, the control unit 29 operates the blower 23, performs temperature control and humidity control, and also performs defrost control.

The temperature control will be described below.
Is based on the detection signal of the temperature sensor 27 so that the temperature in the adjustment target chamber becomes a desired temperature (a target temperature, which is set by the user operating the operation unit 30). And controlling the electric heating pipe 42 of the heat exchanger 24.
Specifically, for example, the control unit 29 obtains a deviation (= target temperature−detected temperature), and when the deviation is smaller than a predetermined −ΔT, the cooling unit 26 (specifically, as in FIG. 6A). The compressor 51) is turned off (that is, the cooling amount of the cooling pipe 41 is set to 0%), and the deviation is −
When ΔT or more, the cooling unit 26 (specifically, the compressor 5
1) is turned on (that is, the cooling amount of the cooling pipe 41 is set to 100%). In addition, the control unit 29 is shown in FIG.
Similarly, the electric heat pipe 42 is controlled so that the total heat output of the entire heat exchanger 24, which is the sum of the cooling amount of the cooling pipe 41 and the heating amount of the electric heat pipe 42, continuously changes according to the deviation. To do. However, the present invention is not limited to the heat output characteristics as shown in FIG. 6 (b).

To explain the humidity control, the control unit 29 controls the humidity of the humidity sensor 28 so that the humidity in the room to be adjusted is the desired humidity (target humidity, and the user operates the operation unit 30). The humidifier 25 is controlled so that

Further, the defrosting control will be described. The control unit 29, based on the timer signal from the timer 31,
Whenever the defrosting time interval (for example, 20 hours) preset by the user operating the operation unit 30 has elapsed, the above-mentioned temperature control and humidity control are stopped for a predetermined defrosting time (for example, 10 minutes). The operation of the blower 23 and the cooling unit 26 is stopped, and the electric heat pipe 42 is operated with a heating amount of 100%, for example, to defrost the fins 43 of the heat exchanger 24. In the present embodiment, the user uses the timer 31 to automatically perform defrosting at predetermined defrosting time intervals. However, the user operates the operation unit 30 to defrost.

Therefore, according to the present embodiment, since there is no heating coil, it is smaller and cheaper than the conventional temperature / humidity adjusting device, and the temperature of the chamber to be adjusted can be adjusted with high accuracy as in the conventional temperature / humidity adjusting device. Can be adjusted.

Further, in this embodiment, in order to adjust the temperature,
Since the electric heat pipe 42 which is thermally coupled to the fin 43 which is thermally coupled to the cooling pipe 41 of the heat exchanger 24 is controlled, the fin 43 itself is at a level corresponding to the total heat output originally required for temperature control. The fins 43 are not cooled down, and the fins 43 are not overcooled. Therefore, according to this embodiment, the adhesion speed of the frost adhering to the fins 43 is slower than that of the conventional temperature and humidity adjusting device, and the defrosting time interval can be lengthened. Therefore, the period during which the temperature of the adjustment target chamber is not adjusted is shorter than that of the conventional temperature and humidity adjusting device, which is preferable. Moreover, since defrosting is not performed as frequently as in the conventional temperature and humidity adjusting device, the operating cost such as an electric charge required for defrosting is reduced.

Further, in the temperature / humidity adjusting device according to the present embodiment, since the fins 43 are not overcooled as described above, the dehumidifying effect of air in the heat exchanger 24 is small.
Less water in the air taken away by the heat exchanger 24,
Since the amount of water that needs to be supplemented by the humidifier 25 is small, it is possible to use a humidifier with a small humidification capacity as the humidifier 25, and it is possible to achieve cost reduction.
The amount of water consumed in the humidifier 25 also decreases.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment.

For example, the cooling unit 26 may be constructed as shown in FIG. 4, parts that are the same as the parts shown in FIG. 3 are given the same reference numerals, and descriptions thereof will be omitted. In this example, the cooling pipe 41 is not used as an evaporator, and the cooling unit 26 has an evaporator 60 that cools brine. Then, the brine cooled by the evaporator 60 is circulated through the cooling pipe 41 by the pump 61. In the present embodiment, the cooling unit 26 constitutes a refrigerator that cools brine.

When it is not necessary to adjust the humidity in the room to be adjusted and only the temperature needs to be adjusted, the humidifier 25 and the humidification sensor are removed in FIG.
