[0002] The common water-cooled laundry drying machine relies on a condenser to complete the condensation of water vapor in the clothes during the drying process.

DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in connection with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0028] In connection with Figures 1-6 The embodiments of the present application provide a clothes treatment device, which comprises:

[0029] The rear cylinder 4, the inner cylinder, the main condenser and the condenser extension part, the rear cylinder 4 comprises a rear cylinder inner wall, the inner cylinder comprises an inner cylinder outer wall, the condenser extension part comprises a space composed of the rear cylinder inner wall and the inner cylinder outer wall, a rear cylinder spray pipe 4-4, a rear cylinder inner wall and an inner cylinder outer wall, the rear cylinder spray pipe 4-4 can spray water on at least one of the wet and hot air in the rear cylinder inner wall, the inner cylinder outer wall and the space composed of the rear cylinder inner wall and the inner cylinder outer wall to perform condensation heat exchange; the main condenser comprises a condensing air duct 1 arranged on the outer wall of the rear cylinder and a condenser spray pipe 1-4 arranged on the condensing air duct 1, the condenser spray pipe 1-4 can spray water on the wet and hot air entering the condensing air duct 1 to perform condensation heat exchange.

[0030] The application forms a double condensing structure by the main condenser including a condensing air duct arranged on the outer wall of the rear cylinder and a condenser spray pipe arranged on the condensing air duct, so that the condenser spray pipe can spray water on the wet hot air entering the condensing air duct to perform condensing heat exchange, and at the same time, the condenser extension part includes the space composed of the inner wall of the rear cylinder and the outer wall of the inner cylinder, the rear cylinder spray pipe, the inner wall of the rear cylinder and the outer wall of the inner cylinder, the rear cylinder spray pipe can spray water on the wet hot air in at least one of the inner wall of the rear cylinder, the outer wall of the inner cylinder and the space composed of the inner wall of the rear cylinder and the outer wall of the inner cylinder to perform condensing heat exchange, so that the main condenser and the condenser extension part form a double condensing structure which simultaneously condenses and cools the wet hot air, improves the dehumidifying efficiency, improves the condensing efficiency, effectively solves the problem that the condenser is usually a small space channel in the overall layout of the washer-dryer, which is not convenient for the steam and the external water source to fully contact, resulting in low condensing efficiency, reasonably utilizes the existing space, prolongs the contact path of the steam and the external water source in the air circulation process, thereby improving the condensing efficiency, and improves the drying efficiency of the washer-dryer.

[0031] In some embodiments, the rear cylinder 4 is provided with a first exhaust port 4-1 and a second exhaust port 4-2, and the condensing air duct 1 is a channel structure with at least three channels, which is provided with a first air inlet 1-1 and a second air inlet 1-2 and a third exhaust port 1-3, the first exhaust port 4-1 is communicated with the first air inlet 1-1 to guide the wet hot air in the rear cylinder 4 into the condensing air duct 1, the second exhaust port 4-2 is communicated with the second air inlet 1-2 to guide the air in the rear cylinder 4 after condensation into the condensing air duct 1, and the third exhaust port 1-3 can transport the air in the condensing air duct 1 to the heating air duct. The first exhaust port and the first air inlet arranged on the rear cylinder and the condensing air duct can also be used to suck the wet hot gas from the inside of the rear cylinder into the condensing air duct through the first air inlet and the first exhaust port, and the wet hot gas is separated into gas and liquid under the action of the water sprayed by the condenser spray pipe, effectively removing the water, so that the gas is dried and recycled into the inner cylinder to continue the drying effect. Through the second exhaust port and the second air inlet, the air after condensing heat exchange can be sucked from the upper part of the inner cylinder into the condensing air duct through the second air inlet and the second exhaust port, and the third exhaust port can effectively discharge the gas in the condensing air duct to the heating air duct, so that the condensing air duct forms a three-channel structure (three-channel characteristic condenser (one end connected with the air blower, and the other two ends connected with the outer cylinder of the washing machine)), and the manifold and the condensing air duct form a whole structure.

[0032] Figure 2It is another expression of the principle of double condensing system. As shown in the figure, the hot air blown by the electric heating enters the drum and can be simply divided into three paths. The first path passes through the condensing air duct 1 for condensing, the second path passes through the rear cylinder 4 for condensing, and the last path directly passes through the second exhaust port 4-2 into the second suction port 1-2, which is a low-efficiency drying cycle.

[0033] The condensing air duct 1 has a first suction port 1-1, a second suction port 21-2, and a third exhaust port 1-3. The third exhaust port 1-3 is located at the upper space and connected with the fan volute assembly. The first suction port 1-1 is located at the lower space and far away from the third exhaust port 1-3. The condenser spray pipe 1-4 is located at the high position of the first suction port 1-1. The steam enters the condensing air duct 1 from the first suction port 1-1 and flows from the low position to the high position. Finally, it is discharged from the condensing air duct 1 through the third exhaust port 1-3. In the process, the external water source is sprayed into the condenser spray pipe 1-4 and mixed with the part of the steam for condensing. The condensed water and the external water are discharged through the first suction port 1-1, the first exhaust port 4-1, and the rear cylinder 4 through the drain port 4-5.

[0034] The second suction port 1-2 of the condensing air duct 1 is located at the high position of the first suction port 1-1 and close to the third exhaust port 1-3. Another part of the steam exists between the inner wall of the outer cylinder and the outer wall of the inner cylinder of the washing machine, which is between the bottom of the outer cylinder and the bottom of the inner cylinder in the example shown in the figure. At this position, there is a rear cylinder spray pipe 4-4 and a water guide structure 4-3 (preferably a water guide rib) arranged in a special pattern. The external water source is sprayed into the rear cylinder spray pipe 4-4 and contacts the part of the steam in the large water passing area of the wind flow extension of the water guide structure 4-3 arranged in a special pattern for condensing. The condensed water and the external water are discharged through the drain port 4-5. Then, the part of the gas enters the condensing air duct 1 through the second exhaust port 4-2 and the second suction port 1-2. A small amount of uncondensed steam in the part of the gas is condensed in the condensing air duct 1 with the help of the external water introduced by the condenser spray pipe 1-4.

[0035] In some embodiments, the first exhaust port 4-1 is located below the second exhaust port 4-2, and the first suction port 1-1 is located below the second suction port 1-2. The first exhaust port of the present application is located below, which can mainly guide the wet and hot steam in the rear cylinder. Most of the steam has not undergone the heat exchange process of the rear cylinder condensing, and the humidity is large. The second exhaust port is located above, which can mainly guide the air after the condensing heat exchange above the rear cylinder. This part of the gas is mainly dry air after dehumidification, so it is located above.

[0036] In some embodiments, the rear wall of the rear cylinder 4 is equally divided into three equal parts from top to bottom along the height direction. The first exhaust port 4-1 is located in the lower one-third of the rear cylinder 4, and the second exhaust port 4-2 is located in the upper one-third of the rear cylinder 4.Figure 4 Figure 4 is a schematic diagram of a double condensing drying machine rear cylinder structure, showing a rear cylinder structure. Generally, the rear cylinder is divided into three equal parts, the second exhaust port 4-2 is located in the upper third, and the first exhaust port 4-1 is located in the lower third. This distribution is because a larger and longer condensate contact area is needed to increase efficiency.

[0037] In some embodiments, the center line of the second exhaust port 4-2 is perpendicular to the rear cylinder wall of the rear cylinder. Generally, the center line of the second exhaust port 4-2 is perpendicular to the rear cylinder wall of the rear cylinder. If it is parallel to the rear cylinder wall of the rear cylinder, it is possible that the pipeline between the second exhaust port 4-2 and the second suction port 1-2 will cause the condensed condensate to fall on the clothes, affecting drying. The condensed condensate from the second exhaust port on the rear cylinder wall will flow down along the inner wall of the rear cylinder, without wetting the clothes and affecting drying, thereby improving the drying degree.

[0038] In some embodiments, the ratio of the diameter of the first exhaust port 4-1 to the diameter of the second exhaust port 4-2 is in the range of 2 / 3 to 4. The ratio of the diameter of the first exhaust port 4-1 to the equivalent diameter of the second exhaust port 4-2 is in the range of 80 / 120 (first preferred specification) to 80 / 20 (second preferred specification), which is optimal. This is because, under the condition that the fan speed remains unchanged, increasing the diameter of the second exhaust port 4-2 or decreasing the ratio will increase the gas passing through path 3, and the ineffective or inefficient circulation will increase, thereby reducing the drying efficiency. However, if the diameter of the second exhaust port 4-2 is relatively small or the ratio of the first exhaust port 4-1 to the second exhaust port 4-2 is large, the gas passing through path 2 will decrease, reducing the efficiency of the rear cylinder condensation and increasing the drying time. In addition, the size of the first exhaust port 4-1 and the second exhaust port 4-2 will also affect the flow rate of the gas passing through the second exhaust port 4-2. If the diameter of the second exhaust port 4-2 is relatively small, the flow rate will be too high, which will easily cause the water flowing out of the rear cylinder shower pipe 4-4 or even the condenser shower pipe 1-4 to be sucked back into the fan and the rear-end pipeline, and then be sprayed back into the drum by the electric heating, thereby reducing the temperature, increasing the humidity, and wetting the clothes again. Considering the limited internal space, the diameter of the second exhaust port 4-2 cannot be too large, as this will cause ineffective heat exchange to increase. Also, the diameter cannot be too small, as this will result in poor condensation effect of the rear cylinder. Therefore, the diameter of the second exhaust port 4-2 is selected to be in the range of 2 / 3 to 4, which can ensure the condensation heat exchange of the rear cylinder and prevent or reduce ineffective heat exchange.

[0039] In some embodiments, the length of the center of the first exhaust port 4-1 and the center of the second exhaust port 4-2 along the horizontal direction in the planar projection of the rear cylinder wall of the rear cylinder 4 is L, the diameter of the rear cylinder 4 is D, and L / D = 0.15-0.35. The diameter of the second air inlet 1-2 is consistent with the second exhaust port 4-2, and the first air inlet 1-1 is consistent with the first exhaust port 4-1. Generally, the horizontal length distance between the second air inlet 1-2 and the first air inlet 1-1 through the two lines of the vertical circle center surface is L in the figure, and the ratio of L to the drum diameter is preferably 0.15-0.35. If L is too long, the heat dissipation area of the air duct will be increased, because the pipeline itself is not heated, and too long will affect the temperature in the cylinder and reduce the efficiency. If it is too short, that is, the opening position of the second exhaust port 4-2 is closer to the first exhaust port 4-1 horizontally, the condensation utilization rate of the rear cylinder area away from the first exhaust port 4-1 will be reduced, and the drying efficiency will be reduced.

[0040] In some embodiments, a plurality of water guide structures 4-3 are further arranged on the inner wall of the rear cylinder, and a drain port 4-5 is further arranged at the bottom of the rear cylinder 4; the rear cylinder spray pipe 4-4 is arranged from the outside of the rear cylinder 4 to the position of the inner wall of the rear cylinder, so as to spray water onto the inner wall of the rear cylinder. The rear cylinder spray pipe of the present application sprays water onto the inner wall of the rear cylinder, which can make the humid hot air complete heat exchange on the inner wall of the rear cylinder, dehumidify and cool down, effectively avoid the clothes being wetted by directly spraying into the rear cylinder, and increase the heat exchange area and improve the heat exchange efficiency.

[0041] In the embodiment, the rear cylinder 4 is a condenser extension due to the introduction of external water source by the rear cylinder spray pipe 4-4, the expansion of water area by the specially arranged water guide structure 4-3, and the air path and power source by the second exhaust port 4-2, the second air inlet 1-2, the exhaust port 1-3, and the fan volute assembly. The machine space is reasonably utilized without increasing the cost of the whole machine, the condensation path is prolonged, the phase change area of heat exchange is increased, the circulation gas flow is increased, the drying efficiency is improved, the time is shortened, and the electricity is saved.

[0042] In some embodiments, when the condensation air duct 1 is further provided with a third exhaust port 1-3, the clothes treatment device further comprises a heating air duct 3 and a heater 5, the heating air duct 3 is provided with an air inlet 2, the air inlet 2 is communicated with the third exhaust port 1-3 of the condensation air duct 1, the other end of the heating air duct 3 can be communicated with the inner cylinder and / or the rear cylinder, and the heater 5 is arranged in the heating air duct 3.

[0043] In some embodiments, a fan 6 is further arranged in the heating air duct 3; and / or, the clothes treatment device is a washer-dryer.
