Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to an evaporator and a clothes dryer. Background Art

[0002] A clothes dryer is a household appliance that uses electric heating to evaporate the water in washed clothes instantly. The working principle of a clothes dryer is to use high-temperature airflow to pass through the surface of the clothes to be dried, heat the clothes, and take away the evaporated water, so that the clothes can be dried quickly.

[0003] When the airflow passes over the surface of the clothes to be dried, some tiny lint in the clothes to be dried will be carried out by the airflow. The above-mentioned lint circulates in the air circulation system with the drying air flow, and will eventually adhere to the heat exchange fins of the evaporator. In order to solve the above problems, in the current dryers, a filter is set at the front end of the evaporator to block the lint. However, there is still the problem that tiny lint passes through the filter and gathers on the heat exchange fins of the evaporator, reducing the heat exchange area. Therefore, in order to ensure the cleanliness of the dryer and the drying effect, the heat exchange fins on the side of the evaporator facing the filter need to be disassembled and cleaned at regular intervals.

[0004] The prior art provides a solution for disassembling the heat exchange fins of the evaporator in the clothes dryer, that is, the heat exchange fins facing the filter are detachably connected to the copper tube by a clamping method. When it is necessary to disassemble this part of the heat exchange fins, the user only needs to pull out this part of the heat exchange fins towards himself. The above-mentioned heat exchange fin disassembly solution requires the user to manually pull out or push to install, which consumes the user's physical strength, is inconvenient to operate, and has a low degree of automation.

[0005] Therefore, there is an urgent need for an evaporator and a clothes dryer to solve the above problems. Utility Model Content

[0038] Figure 1 The following is a partial structural diagram of a clothes dryer provided by an embodiment of the utility model. Figure 1 The present embodiment provides an evaporator and a clothes dryer. The clothes dryer includes a base 30, a condenser 10 and a filter (not shown), and also includes an evaporator 20 provided in the present embodiment. The evaporator 20 is disposed between the condenser 10 and the filter.

[0040] Specifically, due to the path setting of the internal air duct system of the dryer, the high-temperature airflow passes through the evaporator 20 and then flows to the condenser 10. During this process, a large amount of lint will gather on the side of the evaporator 20 close to the filter. Therefore, it is only necessary to set a plurality of detachable first heat exchange fins 200 on the side of the evaporator body 100 facing the filter for easy cleaning.

[0041] More specifically, refer to Figure 2 The evaporator further includes a reinforcing rod 500.
