Long-term humid environment is easy to breed bacteria, causing skin and respiratory infections, and also causing mold growth in the home, which will be detrimental to people's health; therefore, it is necessary to study a heat pump clothes dryer with indoor dehumidification function to achieve an improvement in the indoor environment. Utility Model Content

[0003] The utility model aims to provide a heat pump clothes dryer, which solves the technical problem that the existing heat pump clothes dryer can only dry clothes but cannot improve the indoor humid environment.

[0004] To achieve this purpose, the utility model adopts the following technical solutions:

[0005] The utility model provides a heat pump clothes dryer, comprising a clothes dryer body, wherein an air duct, a compressor and an inner drum are respectively installed in the clothes dryer body, a fan, a condenser and an evaporator are sequentially arranged in the air duct, and the compressor, the evaporator and the condenser are sequentially connected through a refrigerant pipe; the clothes dryer body is respectively provided with an air outlet connected to the inner drum and an air inlet connected to the air duct;

[0006] A baffle assembly is provided in the air duct between the air inlet and the air outlet, and the baffle assembly is used to open or block the air duct to connect or separate the air inlet and the air outlet. The baffle assembly blocks the air duct, and the air inlet, the air duct, the inner cylinder, the air outlet and the room form an external circulation.

[0007] The heat pump clothes dryer is provided with a baffle assembly in the air duct between the air inlet and the air outlet. The air duct between the air inlet and the air outlet is opened or blocked by the baffle assembly. When the baffle assembly blocks the air duct, the air inlet, the air duct, the inner drum, the air outlet and the indoor room form an external circulation to dry the indoor environment and reduce the indoor air humidity. This enriches the function of the heat pump clothes dryer, improves the intelligence of the heat pump clothes dryer and provides protection for people's health.

[0008] As a preferred solution of the above-mentioned heat pump dryer, the baffle assembly is rotatably disposed in the air duct and can be switched between an open state and a blocked state.

[0016] When the filter assembly is taken out from the air duct, the baffle assembly is reset under the driving of the elastic reset member to be in the blocking state.

[0017] When the filter assembly is installed in the air duct, the baffle assembly can be in an open state, and the heat pump dryer can perform drying operations at this time; when the filter assembly is taken out of the air duct, the baffle assembly can be reset under the drive of the elastic reset member to be in a blocked state, thereby enabling the dryer to be in external circulation operation. The baffle assembly is set in this position, which makes little improvement to the original structure of the heat pump dryer and has a low cost; and the state switching of the baffle assembly can be achieved by taking and placing the filter assembly, and the operation is relatively simple.

The baffle assembly can be abutted against the limiting structure when it is in the blocking state.

[0022] The setting of the limiting structure can limit the rotation of the baffle assembly on the reset path, thereby preventing the baffle assembly from rotating excessively when resetting and preventing the baffle assembly from being unable to block the air duct.

[0023] As a preferred solution of the above heat pump clothes dryer, a condensed water collecting device for collecting condensed water is provided below the evaporator.

[0024] The setting of the condensed water collection device facilitates the collection of the condensed water generated by the evaporator for centralized treatment to prevent it from dripping into the air duct.

[0044] like Figure 2 and Figure 3 As shown, a clothing inlet is provided on the front support 10 of the dryer body, and the clothing inlet is an air outlet 11. An air inlet 12 is provided on the front support 10, and the air inlet 12 is located below the air outlet 11; a baffle assembly 13 is provided in the air duct 1 between the air inlet 12 and the air outlet 11. The clothing inlet is the air outlet 11, and the existing clothing inlet is used to achieve air outlet, without the need to additionally provide the air outlet 11; the air inlet 12 and the baffle assembly 13 are both provided on the front support 10, which can fully utilize the existing structure of the heat pump dryer, and the modification is relatively small.

[0045] Optionally, a wind shield cover (not shown in the figure) can be opened and closed at the air inlet 12, and the opening and closing of the air inlet 12 can be controlled by setting the wind shield cover. A machine door (not shown in the figure) can be opened and closed at the air outlet 11, and the opening and closing of the air outlet 11 can be controlled by setting the machine door, so as to switch the heat pump dryer between internal circulation and external circulation.
