Problems solved by technology

Despite these methods, the energy consumption and time of the drying process remain high
And drying clothes at high temperature will damage the fabric itself and cause wrinkles and shrinkage easily
[0006] The drying speed of the above-mentioned clothes drying device is still not improved, and the time required for the drying process is still relatively long.

Embodiment 1

[0038] Such as figure 1 with figure 2 As shown, the rear end of the drum 1 described in this embodiment is coaxially provided with a hollow drum shaft 3, which is also a supporting rotating shaft. A direct drive motor is installed on the drum shaft to drive the rotation, and the hollow part of the drum shaft 3 forms An air extraction channel 31 communicated with the inside of the drum, and an air extraction hole 32 communicated with a vacuum device is provided on the side of the drum shaft 3 .

[0039] The drum shaft 3 is provided with a vent pipe 4 that communicates the inside of the drum 1 with the outside world. The vent pipe 4 is arranged to rotate relative to the drum shaft 3. Both ends extend from the drum shaft 3. The end of the drum shaft 3 is connected to the vent pipe 4. The outer end of the vent pipe 3 is provided with the gas distribution valve 10 .

[0040] The drum 1 is provided with a partition 5, the partition 5 divides the interior of the drum into a clothe...

Embodiment 2

[0042] Such as figure 1 with figure 2 As shown, the partition 5 described in this embodiment is an arc-shaped plate, which is installed at the joint between the drum shaft 3 and the rear end of the drum 2, and the periphery is smoothly transitioned to the inner wall of the rear end of the drum 2. The radius r of the partition is equal to The radius R inside the drum satisfies: R / 5≤r≤R (see figure 1 ). This structure prevents the deformation of the clothes caused by the partition structure during the drying process, and does not affect the storage capacity of the clothes inside the drum. Or, the dividing plate 5 is a circular flat plate matching the radial section of the drum, directly separating the inner space of the drum into two cylindrically structured spaces (refer to image 3 ).

[0043] The maximum axial length K of the air pumping chamber 12 and the axial length L of the drum 1 satisfy K<L / 10.

Embodiment 3

[0045] Such as figure 1 with figure 2 As shown, the outer chamber 2 described in this embodiment is composed of an outer cylinder 20 arranged outside the drum, the drum 1 is coaxially arranged in the outer cylinder 20, and the heat transfer medium 8 is liquid, and is arranged between the drum 1 and the outer cylinder 20 Between, the height of the liquid level is higher than the radius difference between the drum 1 and the outer cylinder 20. The heat conduction medium is a liquid with better heat conduction performance such as water or heat conduction oil, preferably water. The wall of the outer cylinder below the drum protrudes outwards, forming a concave placement space 21 inside, the heater 9 is arranged in the placement space 21, and the minimum distance between the heater and the drum is greater than that between the drum and the outer cylinder The minimum radius difference.

[0046] During the rotation of the drum, the lower part of the drum is always in contact with ...

Abstract

The invention discloses a low-pressure clothes dryer which comprises a sealed rotatable roller, an outer chamber, a heating device, an evacuating device, an air distribution valve, a heat-conducting medium and a heater, wherein the outer chamber is used for containing the roller, the heating device is used for heating the roller, the evacuating device is used for pumping air in the roller, the air distribution valve is used for controlling communication of the inside of the roller and the outside to adjust the internal air pressure of the roller, the heating device is arranged outside the roller and inside the outer chamber, the heat-conducting medium is used for transferring heat for the outer surface of the roller, and the heater is arranged in the heat-conducting medium. A hollow roller shaft is coaxially arranged at the rear end of the roller, a vent pipe is arranged in the roller shaft, the inside of the roller is communicated with the outside by the aid of the vent pipe, the vent pipe and the roller shaft rotate relatively, two ends of the vent pipe extend out of the roller shaft, the space between the tail end of the roller shaft and the vent pipe is sealed, and the air distribution valve is arranged at one external end of the vent pipe. The low-pressure clothes dryer has the advantages that drying energy consumption is reduced, clothes drying is accelerated, and clothes drying efficiency is improved.

Description

technical field [0001] The invention relates to a clothes dryer, in particular to a clothes dryer which utilizes the conditions of low pressure and low boiling point to realize fast drying of clothes. Background technique [0002] Whether it is drying clothes in the sun or using drying equipment to dry clothes, the ultimate goal is to remove the moisture contained in the clothes to make the clothes dry. Since drying clothes is limited by weather factors, more and more various drying equipment are used to dry clothes. [0003] In a drying mechanism used in a clothes dryer or a washer-dryer, a heating method in which a heater heats air is often used. Existing electric heating dryers generally use heating wires or heating tubes as the heat source. Such products have high energy consumption, long drying time and poor safety. In order to reduce energy consumption, a heat pump dryer has been developed, which uses a heat pump system to strengthen the recycling of heat, improve he...
