Embodiment approach 1

[0036] Next, use figure 1 The laundry dryer according to Embodiment 1 of the present invention will be described.

[0037] figure 1 It is a schematic diagram of the clothes dryer in Embodiment 1 of this invention.

[0038] Such as figure 1 As shown, the clothes dryer 1 of this embodiment at least includes: a heat pump device 7 having an evaporator 5 and the like, a drying chamber 9, an air duct 10 for circulating drying air in the direction of arrow A, a blower 8, The discharge part 13 which discharges water, the control part 16, etc. are provided.

[0039] The heat pump device 7 is configured by connecting the compressor 2 , the condenser 3 , the expansion device 4 , and the evaporator 5 through a pipe 6 , and is configured to circulate the refrigerant therebetween. In this structure, the compressor 2 compresses the refrigerant. The condenser 3 releases the heat of the high-temperature and high-pressure refrigerant compressed by the compressor 2 . The expansion devic...

[0083] Next, use Figure 6A with Figure 6B A clothes dryer according to Embodiment 2 of the present invention will be described.

[0084] Figure 6A It is a schematic diagram at the time of lint removal of the clothes dryer in Embodiment 2 of this invention. Figure 6B It is a schematic diagram at the time of water removal of the clothes dryer of this embodiment.

[0085] Such as Figure 6A with Figure 6B As shown, the clothes dryer of this embodiment has the following structure: the water spray range 17 sprayed from the spray unit 13 to the evaporator 5 is set to use the dehumidified water generated by the evaporator 5 The water removal range 18 in which water is removed is set as a part of the evaporator 5 . The other configurations are the same as those in Embodiment 1, and the same reference numerals are assigned to the same configurations, and Embodiment 1 will be referred to for detailed description.

[0086] That is, the position where water is jetted from the ...

Embodiment approach 3

[0090] Next, use Figure 7 A clothes dryer according to Embodiment 3 of the present invention will be described.

[0091] Figure 7 It is a schematic diagram at the time of lint removal of the clothes dryer in Embodiment 3 of this invention.

[0092] Such as Figure 7 As shown, the clothes dryer according to this embodiment has the following structure: the spray part 13 is provided above the upstream side end surface 5b of the evaporator 5 where the drying air flows in, and the spray part 13 is directed toward the evaporator. The end face 5b on the upstream side of 5 sprays water. The other configurations are the same as those in Embodiment 1, and the same reference numerals are assigned to the same configurations, and Embodiment 1 will be referred to for detailed description.

[0093] That is, if Figure 7 As shown, the discharge part 13 is provided above the evaporator 5 on the downstream side with respect to the flow direction of the drying air. And water is sprayed f...

Abstract

The clothes dryer (1) of the present invention is equipped with: a drying chamber (9); an air duct (10), which circulates the drying air discharged from the drying chamber (9) to the drying chamber (9); a heat pump device (7), It is arranged in the air duct (10), and is formed by connecting the compressor (2), the condenser (3), the expansion device (4) and the evaporator (5) through the pipeline (6) that circulates the refrigerant; the air blower (8), which sends air to the air duct (10); the spraying part (13), which sprays water toward the evaporator (5); and the control part (16), which controls the drying operation. Furthermore, the control unit (16) controls to operate the compressor (2) after the water is sprayed from the spray unit (13). Thereby, scale does not adhere to the evaporator (5), and lint can be removed.

Description

technical field [0001] The present invention relates to a clothes dryer for drying objects to be dried, such as clothes, and a method for cleaning an evaporator of the clothes dryer. Background technique [0002] Conventionally, with regard to clothes dryers equipped with heat pump devices, lint generated from fabric products such as clothes is mixed into drying air. The mixed lint adheres to the air blower, heat exchanger, etc. installed in the circulation air duct, and accumulates. As a result, it becomes the cause of the function reduction of a blower and a heat exchanger. Therefore, the conventional clothes dryer is provided with a lint filter for trapping the lint mixed in the drying air in the circulating air duct. [0003] However, since the drying air flowing in the circulation duct needs to ensure a constant air flow rate, the mesh of the lint filter cannot be made finer. Therefore, it is difficult to use the lint filter to completely remove the lint from the dry...
