Problems solved by technology

[0003] The existing heat pump clothes dryer adopts a vertical compressor, and the compressor, evaporator, and condenser are placed at the bottom of the drum: the compressor and heat exchanger are listed on the left and right sides (see figure 1 ), the volume of the evaporator and the condenser each account for about half of the bottom space, limited by the height of the bottom space of the drum, the compressor cannot be selected with a large capacity, and the evaporator and condenser cannot have enough dehumidification and heating areas. Heat pump dryers take longer to dry
[0004] Insufficient lint filtration in existing heat pump dryers can lead to clogging of the evaporator aluminum sheets in the heat pump module, resulting in reduced drying efficiency

Embodiment 1

[0038] Such as figure 2 As shown, a heat pump dryer includes a rotatable drying drum 1, a heat pump system, and a circulating air system. The heat pump system includes a compressor 2, a condenser 3, a throttling device 4, and an evaporator 5. The condenser 3 and the evaporator 5 are arranged at the rear of the clothes drying drum 1 .

[0039] There is also a motor driving the rotation of the drying drum 1 below the drying drum 1. The output end of the motor is connected to a belt, and the belt is also connected to the drying drum 1. The rotation of the output end of the motor drives the belt to rotate, and then drives the drying drum to rotate. , so that the clothes inside the drying drum 1 are tumbled and fully contacted with dry and hot air.

[0040] A heat dissipation fan is also arranged under the drying drum 1. When the internal load of the compressor exceeds the rated load, it plays a role in regulating the load. A temperature sensor can be installed to control the ope...

Embodiment 2

[0043] Such as image 3 As shown, a heat pump dryer includes a rotatable drying drum 1, a heat pump system, and a circulating air system. The heat pump system includes a compressor 2, a condenser 3, a throttling device 4, and an evaporator 5. The condenser 3 and the evaporator 5 are arranged at the rear of the clothes drying drum 1 .

[0044] A compressor 2 is also arranged under the drying drum 1, and the compressor 2 compresses the refrigerant, transfers the generated high-temperature and high-pressure refrigerant to the condenser 3, and the refrigerant releases heat after passing through the condenser 3, and the released heat is used for In order to heat the working air flow passing through the condenser 3, the refrigerant passes through the condenser and is regulated by the throttling device 4 to become a low-pressure and low-temperature humid gas. , absorb heat from the hot and humid air, turn it into a low-temperature and low-pressure saturated gas, enter the compressor...

Embodiment 3

[0048] The drying method of the heat pump clothes dryer described in this embodiment starts with the drying of clothes, the working airflow in the air duct 6 passes through the condenser 3, and the condenser 3 dissipates heat to heat the working airflow and passes through the dry heat of the drying drum 1 The air inlet 9 enters the inside of the drying drum 1, mixes with the water vapor of the clothes to form hot and humid air, enters the air duct 6 through the hot and humid air outlet 8, passes through the evaporator 5, and the evaporator 5 condenses the water vapor in the hygroscopic hot air into condensed water , the condensed water flows down into the water collecting box 10, and the working air flow passes through the condenser 3 again to be heated, and a new drying cycle starts until the drying ends.

[0049] During the drying process, the lint in the clothes enters the air duct 6 with the hot and humid air, and adheres to the windward side of the lower part of the evapor...

Abstract

The invention relates to a heat-pump clothes dryer and a clothes drying method. The heat-pump clothes dryer comprises a clothes drying drum, a heat pump system and a circulating air system. The heat pump system comprises a compressor, a condenser, a throttling device and an evaporator, and at least the condenser and the evaporator are arranged on the rear portion of the clothes drying drum. The evaporator is arranged below the condenser, and a windward side of the evaporator is arranged below the evaporator. Mounting space of the compressor is larger, the compressor can be a horizontal compressor with large capacity, clothes drying efficiency is improved, and drying time is shortened; condensed water after water steam condensation in operating current passing the evaporator flows from top to bottom, threads attached to the windward side of the evaporator can be flushed off, blockage of the evaporator by the threads and smoothness in flow of the operating flow are avoided, drying efficiency is reduced, heat exchange area of the condenser and the evaporator is sufficiently utilized, efficiency is improved and energy source is saved.

Description

technical field [0001] The invention relates to the field of clothes dryers, in particular to a heat pump clothes dryer and a clothes drying method. Background technique [0002] When using a heat pump system to dry clothes, the heated air is generally sent from the rear of the outer cylinder into the inner cylinder through the air duct to exchange heat with the wet clothes, and the humid and cooled air is condensed to dehumidify and then heated to continue drying the clothes. Chinese patent application number 200610153406.9 discloses a clothes drying device. Among them, the air heated by the heater in the heat pump is sent into the water tank as the drying room, and the air exhausted from the water tank passes through the filter unit and returns to the heat pump, and is dehumidified by the heat absorber before being sent to the heater. Form air circulation channels. A lint filter is provided in the filter unit, and a duct communicating with the air outlet and the air inle...
