Embodiment approach 1

[0022] figure 1 is a schematic view of the drying device according to Embodiment 1 of the present invention as a clothes dryer, figure 2 is a schematic diagram showing the main parts of the heat pump of the drying device, image 3 It is a schematic side view of the upstream side heat exchanger and the downstream side heat exchanger of this drying apparatus.

[0023] exist Figure 1 ~ Figure 3 Among them, the drying chamber 1 accommodates objects to be dried such as clothes 20 . The heat pump 2 is connected to the drying chamber 1 through the circulation air path 3 . Here, the circulating air duct 3 is connected to the drying chamber 1 . The drying chamber 1 is provided with an air supply port 4 for supplying drying air from a circulating air passage 3 and an exhaust port 5 for discharging the drying air. The heat pump 2 has a compressor 6 , an evaporator 8 , a condenser 7 , lines 9 and a pressure reducing valve 10 . Here, the compressor 6 compresses the refrigerant. I...

Embodiment approach 2

[0048] Figure 4 It is a schematic diagram of the drying apparatus in Embodiment 2 of this invention. In Embodiment 2 of the present invention, the same reference numerals are assigned to the same constituent elements as in Embodiment 1, and detailed description thereof will be omitted, and differences will be described.

[0049] In Embodiment 2 of the present invention, a circulation pump 16 is provided on the circulation path of the heat exchange pipe (heat moving part) 14a, and the heat medium is passed through the upstream side heat exchanger 12 and the downstream side heat exchanger 13 by the circulation pump 16. cycle. This point is different from Embodiment 1 of the present invention.

[0050] The circulation pump 16 sucks the heat medium from the lower heat exchange pipe 14 a of the downstream heat exchanger 13 , and pressurizes and sends the heat medium to the lower heat exchange pipe 14 a of the upstream heat exchanger 12 . The circulation pump 16 operates simulta...

Embodiment approach 3

[0056] Figure 5 is a schematic diagram of a drying device according to a third embodiment of the present invention as a clothes dryer, Image 6 is a schematic side view of the heat exchanger on the upstream side of the drying device, Figure 7 It is a schematic side view of the downstream side heat exchanger of this drying apparatus. In Embodiment 3 of the present invention, the same reference numerals are attached to the same components as those in Embodiment 1, detailed description thereof will be omitted, and differences will be described.

[0057] Embodiment 3 of the present invention is different from Embodiment 1 in that a heat pipe 26 is used as a heat transfer unit. That is, the upstream side heat exchanger 12 and the downstream side heat exchanger 13 connected by four heat pipes 26 constituting the heat transfer section are disposed on the left and right adjacent sides of the evaporator 8 in the circulating air duct 3 . The heat pipe (heat transfer portion) 26 is ...

Abstract

A drying device comprising a drying chamber, a fan, a circulation flow path, and a heat pump. The heat pump comprises a compressor, an evaporator, a condenser, a pressure reducing valve, a pipe path, an upstream heat exchanger provided in the circulation flow path at a position between the drying chamber and the evaporator and exchanging heat with air for drying, a downstream heat exchanger provided between the evaporator and the condenser and exchanging heat with the air for drying, and a heat moving section for circulating a heat medium to the upstream heat exchanger and the downstream heat exchanger. The drying device is configured so that the heat of the air for drying is moved from the upstream heat exchanger to the downstream heat exchanger through the heat medium.

Description

technical field [0001] The present invention relates to a drying device using a heat pump. Background technique [0002] Figure 13 It is a schematic diagram of a drying device using a conventional heat pump. That is, the drying device is equipped with a heat pump composed of a compressor 101, a condenser 102, and an evaporator 103, and releases the heat released from the condenser 102 into the air to form warm air, and the warm air is sent to the dryer by the air blower 104. Room 105. Clothes 106 and the like as objects to be dried in drying chamber 105 are heated and dried by blowing warm air. The warm air that has passed through the clothes 106 and becomes humid is deprived of heat by the evaporator 103 of the heat pump, and when it becomes below the dew point, the moisture is condensed and recovered as drain water. The wind passing through the evaporator 103 is introduced into the condenser 102 again to be heated, and dry warm air is formed to dry the clothes 106 . T...
