0002

2. Description of the Related Art Conventionally, dehumidifying drying using a dehumidifier and heating drying using hot air have been widely used to dry clothes. Figure 4 shows a conventional heating drying method, in which 1 is a fan that circulates the air, 2 is a heating means that heats the air, and 3 is a heating device that heats the air.
is a rotating drum in which clothes 4 are placed.

In the above structure, the air circulated by the fan 1 is heated by the heating means 2, becomes warm air, and enters the rotating drum 3, and the rotation of the rotating drum 3 evaporates the moisture in the clothes 4 inside the drum. , the clothes 4 are dried by exhausting moisture.

On the other hand, FIG. 5 shows a conventional dehumidifying and drying system, in which 5 is a cabinet, 6 is a fan for creating air circulation, 7 is a dehumidifying means for dehumidifying moisture in the air, and 8 is clothing. The above-mentioned fan 6, dehumidifying means 7 and clothes 8 are housed in the cabinet 5.

In the above configuration, the air circulated by the fan 6 condenses moisture in the air by the dehumidifying means 7 and recovers it as water, and the heat generated by the dehumidifying means 7 is used to raise the temperature of the air. By this, dry air is created and sent into the cabinet 5 and applied to the clothes 8.
It dries.

[Problem to be Solved by the Invention] However, in the above heating drying method, the heated air contains moisture.
Warm air is not suitable for removing moisture from clothes, and cannot be dried efficiently.

On the other hand, in the dehumidifying and drying method, if the temperature of the air entering the dehumidifying means becomes high, the dehumidifying means may become overloaded and may not operate. Furthermore, low-temperature air has low humidity and cannot be expected to be dried by dehumidifying means.

An object of the present invention is to solve the problems of these two conventional methods and to provide a clothes drying device that can ensure constant drying performance regardless of room temperature or indoor humidity.

[0009]

[Means for Solving the Problems] In order to achieve the above object, the clothes drying device of the present invention includes a fan for creating air circulation, a first sensor for detecting room temperature, and the first sensor. a heating means for warming the air that has passed through the heating means, a second sensor that detects the temperature of the air that has passed through the heating means, a dehumidifying means that dehumidifies the air that has passed through the second sensor, and a temperature detected by the first sensor. a first comparison means for comparing whether the temperature is such that the dehumidification can be performed by operating the dehumidification means or the temperature at which the heating means should be operated; A second comparing means compares whether the temperature is such that the dehumidifying means does not overload or is the optimum temperature for drying with the dehumidifying means stopped, and the heating is performed based on information from the first and second comparing means. and a control means for controlling the dehumidifying means.

[Operation] With the above configuration, the clothes drying device of the present invention has the following functions:
A fan circulates the entire air, a first sensor detects the room temperature, the air whose temperature has been detected is heated by a heating means, a second sensor detects the temperature of the heated air, and a second sensor detects the temperature of the heated air. The air whose temperature has been detected is dehumidified by the dehumidifying means. The signal detected by the first sensor is compared by the first comparing means with the temperature to be heated by the heating means and the temperature to be dehumidified by the dehumidifying means, and the signal detected by the second sensor is compared with the temperature to be heated by the heating means and the temperature to be dehumidified by the dehumidifying means. When operating the dehumidifying means, the temperature at which the dehumidifying means does not become overloaded is compared with the optimal temperature for drying with the dehumidifying means stopped, and that information is input to the control means, where it is determined and controlled. The heating means and the dehumidifying means are controlled from the means, and clothes can be efficiently dried with dry warm air suitable for drying clothes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 9 is a fan that creates air circulation, 10 is a first sensor that detects room temperature, 11 is a heating device that warms the air that has passed through the first sensor 10, and 12 is a device that is heated by the heating device 11. a second sensor for detecting the temperature of the air; 13 is a dehumidifying means for dehumidifying the air that has passed through the second sensor 12; 14 is a dehumidifying means for dehumidifying the air that has passed through the second sensor 12;
This is a control section that controls the heating means 11 and the dehumidifying means 13. The control unit 14 includes a first comparison unit 15 that compares whether the temperature detected by the first sensor 10 is a temperature at which dehumidification can be performed by operating the dehumidification unit 13 or a temperature at which the heating unit 11 should be operated. , when the temperature detected by the second sensor 12 operates the dehumidifying means 13, the dehumidifying means 1
3 is a temperature that does not cause overload or is an optimum temperature for drying with the dehumidifying means 13 stopped; and the first and second comparing means 15 and 16. It has a control means 17 that controls the heating means 11 and the dehumidification means 13 based on information.

With the above-described configuration, air circulated by the fan 9 enters the warehouse from the room and passes through the first sensor 1.
0, the temperature is detected. Information detected by the first sensor 10 is input to the control unit 14. The air whose temperature is detected by the first sensor 10 is heated by the heating means 11 . The temperature of the heated air is detected by the second sensor 12. Information detected by the second sensor 12 is input to the control unit 14. The air whose temperature has been detected by the second sensor 12 enters the dehumidifying means 13 and is dehumidified. The air dehumidified by the dehumidifying means 13 becomes hot and dry air, which hits the clothes in the refrigerator and dries them.

FIG. 2 shows the entire clothes dryer comprising the fan 9, the first sensor 10, the heating means 11, the second sensor 12, the dehumidifying means 13 and the control section 14 as described above. It is suspended in the refrigerator interior 19, and hot, dry air is supplied as shown by the arrow.

FIG. 3 shows the control means 17 in the control section 14 of FIG.
The control method for the information from the first comparing means 15 and the second comparing means 16 is shown in FIG. OFF is the first and second comparison means 15,
This is the control content of the heating means 11 and the dehumidifying means 13 in response to the information No. 16.

The operation of FIG. 3 will be explained using an example. now,
Assuming that both the room temperature and the supply air temperature are 22°C when starting operation, this temperature is first detected by the first sensor 10, and the first sensor 10 detects this temperature.
is inputted to the comparison means 15. The first comparison means 15 is
The input temperature is compared with the comparison temperatures of 10° C. and 25° C. in FIG. 3 and outputted to the control means 17. Similarly, this temperature is detected by the second sensor 12 and inputted to the second comparing means 16. The second comparing means 16 compares the input temperature with FIG.
The comparative temperatures of 30° C. and 40° C. are compared and outputted to the control means 17. Here, the control means 17 controls the heating means 11 to 30° C. in response to an input of a room temperature of 10° C. or more and less than 25° C. and a supply temperature of less than 30° C.
Turn on the dehumidifying means 13 by repeating turning it on for seconds and turning it off for 30 seconds.
This control will continue.

On the other hand, when the temperature detected by the second sensor 12 by the heating means 11 becomes 30° C. or higher, the heating means 11 is turned off and only the dehumidification means 13 is turned on. Also,
When the temperature detected by the second sensor 12 becomes less than 30° C., the heating means 11 repeats turning on for 30 seconds and turning off for 30 seconds again. As a result, the temperature detected by the second sensor 12 is always after 30°C, and the heat generated by the dehumidifying means 13 creates dry air at 40°C or higher.

[0017] In other cases as well, when the room temperature is less than 10°C, the dehumidifying means 13 is turned off and the supply air temperature is kept at around 40°C, and when the room temperature is above 10°C and less than 25°C, the dehumidifying means 13 is turned on and the supply air temperature is reduced. Control is performed to turn on the dehumidifying means and turn off the heating means when the room temperature is around 30° C. and 25° C. or higher.

Heating means 11 and dehumidifying means 13 as described above
Through this control, dry air at a temperature of 40°C, which has been shown through experiments to be optimal for drying clothes, is constantly produced regardless of the normal outside temperature, and is applied to the clothes to dry them.

[0019]
