Embodiment 1

[0040] This embodiment introduces a drying equipment, including a drying part, a drying air duct 2, a first heat exchanger 3 and a compressor 5. The outlet of the drying air duct 2 is connected to the drying part, and the first heat exchange The device 3 includes a first flow channel and a second flow channel through which the internal working fluid can exchange heat. The working fluid in the drying air channel 2 flows through the first flow channel, and the working fluid discharged from the compressor 5 flows through the second flow channel to compress The machine 5 is set inside the drying air duct 2.

[0041] In the present invention, by arranging the compressor 5 inside the drying air duct 2, the heat dissipated during the operation of the compressor 5 is dissipated to the inside of the drying air duct 2, and the compressor 5 is also used as an auxiliary heater in the drying air duct 2. But the existence, thereby speeding up the heating speed of the drying system, and improvi...

Embodiment 2

[0048] Such as Figure 2-4 As shown, the difference between this embodiment and the first embodiment is that the inlet of the drying air duct 2 is connected to the drying drum 1, so that a circulation path is formed between the drying air duct 2 and the drying drum 1; preferably, the drying air The inlet of the channel 2 is connected with the outer space of the dryer, and the drying cylinder 1 is connected with the outer space of the dryer via an exhaust pipe.

[0049] The inlet of the compressor 5 is connected to the drying cylinder 1, and the discharge pipe 7 of the compressor 5 is connected to the discharge pipe of the dryer; preferably, the discharge pipe 7 of the compressor 5 passes through the throttling device 4 and / or gas-liquid separation The device is connected with the discharge pipe of the dryer; when the discharge pipe 7 of the compressor 5 is connected with the discharge pipe of the dryer through the throttle device 4 and the gas-liquid separation device, the thrott...

Embodiment 3

[0054] Such as figure 2 As shown, the difference between this embodiment and the first and second embodiments is that there is a gap between the outer wall of the compressor 5 and the inner wall of the drying air duct 2 for the passage of working fluid.

[0055] The present invention realizes the circulation of working fluid by providing a gap between the outer wall of the compressor 5 and the inner wall of the drying air duct 2.

[0056] Preferably, there are gaps between the compressor 5 and the inner wall of the drying air duct 2 on the outer periphery thereof. In order to achieve the above structure, the compressor 5 can be fixed inside the drying air duct 2 through a bracket.

[0057] With the above arrangement, the operating compressor 5 fully exchanges heat with the vapor flowing to the compressor 5, thereby further improving the energy efficiency of the drying system.

Abstract

The invention relates to drying equipment. The drying equipment comprises a drying portion, a drying air channel, a first heat exchanger and a compressor, wherein the outlet of the drying air channelcommunicates with the drying portion, the first heat exchanger comprises a first flow channel and a second flow channel, working media in the first flow channel and the second flow channel can be in heat exchange, a working medium in the drying air channel flows through the first flow channel, the working medium discharged by the compressor flows through the second flow channel, and the compressoris arranged in the drying air channel. The compressor is arranged in the drying air channel, so that heat radiated when the compressor operates is dissipated to the inside of the drying air channel;and the compressor also serves as an auxiliary heater in the drying air channel, thereby increasing the heating speed of the drying system and improving the drying efficiency. The compressor is arranged in the drying air channel, so that the running compressor exchanges heat with steam flowing to the compressor, the temperature of the compressor is reduced while the temperature of the steam is increased, the compressor is cooled, and the fault caused by overheating of the compressor is avoided.

Description

Technical field [0001] The invention relates to a drying device, in particular to a clothes dryer for drying clothes. Background technique [0002] The dryer is one of the common household appliances, and its main function is to quickly dry wet clothes. The main heat transfer medium of the existing clothes dryer is air, and the principle of drying is to heat the air in the clothes dryer, and then transfer the heat to the clothes through the hot air, and accelerate the separation of water molecules in the clothes from the clothes. Thereby drying the clothes. There are usually two ways to heat the air, one is to heat the air through an electric heating wire, and the other is to heat the air through a refrigerant system such as the condenser of a heat pump system. Due to the relatively low enthalpy value of air, which means that the heat transfer per unit mass of air is limited, the drying time of traditional clothes dryers is relatively long. Take an 8 kg clothes dryer as an exam...
