Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the description of the specific embodiments is intended to be illustrative only and is not intended to be limiting.

Example 1

As shown in fig. 1, a dehumidifier with a cross-flow fan includes a body 1, a controller (not shown), a compressor 2, an evaporator 3, a condenser 4, a throttling element, a water pan 5, a water tank 6, and a fan.

An air inlet 8 and an air outlet 7 are respectively arranged on the shell, and the evaporator, the condenser and the fan are sequentially arranged between the air inlet and the air outlet. A filter screen (omitted in the figure) is also arranged between the air inlet and the evaporator. The air inlet side of the fan is tightly attached to the condenser, the air outlet side of the fan is tightly attached to the air outlet, a water receiving disc is arranged below the evaporator, and the water receiving disc is communicated with the water tank. The throttling element is a capillary tube or an electronic expansion valve.

The fan is a cross-flow fan comprising an impeller 11 rotatably positioned in the body and a motor 12 driving the impeller in rotation, the axis of rotation of the impeller being arranged vertically.

The machine body comprises a base 1-2 and a machine body 1-1 arranged on the base, the machine body is in a vertically arranged cylindrical shape, an air outlet is formed in the front of the machine body, and an air inlet is formed in the rear of the machine body. The impellers of the evaporator, the condenser and the fan are all arranged in the machine body. And a motor, a compressor, a water receiving tray and a water tank of the fan are arranged in the base. The water pan is arranged below the evaporator. The water receiving tray is communicated with the water tank through a drain pipe (omitted in the figure).

The vertical cross-flow fan is adopted, so that the volume and the floor area of the dehumidifier are greatly reduced, and the dehumidifier is convenient to move and store.

The compressor, the condenser, the throttling element and the evaporator are main parts of a refrigeration system of the dehumidifier. The compressor, the condenser, the throttling device and the evaporator are communicated in sequence through pipelines (omitted in the figure) to form a refrigerant circulation flowing channel: the exhaust port of the compressor is communicated with the inlet of the condenser through an exhaust pipe (omitted in the figure), the outlet of the condenser is communicated with the inlet of the evaporator through a throttling element, and the outlet of the evaporator is communicated with the suction port of the compressor through a return pipe (omitted in the figure), so that a circulation channel is formed.

In the whole circulation process: the compressor, which is the heart of the entire system, acts to compress and transport refrigerant and causes a low pressure in the evaporator and a high pressure in the condenser; the throttling element plays a role in throttling and depressurizing the refrigerant and regulates the flow of the refrigerant entering the evaporator; the evaporator is a device which causes air condensation, the refrigerant absorbs air heat in the evaporator, and the air is condensed when meeting cold, thereby achieving the aim of dehumidification; the condenser is a heat output device, and heat extracted from the evaporator and converted into heat by the work consumed by the compressor are carried away by air through the condenser.

Example 2

The difference from example 1 is that:

the machine body comprises a main machine body 1-3 and auxiliary machine bodies 1-4 arranged at two ends of the main machine body, wherein the main machine body is a horizontally arranged shell.

The front part of the main body is provided with an air outlet, and the rear part of the main body is provided with an air inlet; the evaporator, the condenser, the impeller of the fan and the water pan are all arranged in the main body. The rotation axis of the impeller is arranged horizontally.

As shown in fig. 11, the motor of the fan is provided in the right sub-body, and the compressor is provided in the left sub-body. The water tank is also arranged in the auxiliary machine body on the right side, and the water receiving tray is communicated with the water pump 13 through a water discharge pipe (omitted in the figure).

Because adopt horizontal arrangement and press close to the cross-flow fan on ground, increased the width of air outlet output air current to make the air current directly blow ground, effectively strengthened the drying effect to ground, and the motor and the compressor that the both sides were arranged make the focus of whole compressor, are convenient for carry.

Finally, it should be noted that the above-mentioned list is only a specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
