DETAILED DESCRIPTION

[0041] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0042] According to an embodiment of the present application, a clothing processing device embodiment is provided, such as Figure 1-5 As shown, the clothes processing equipment includes a clothes processing barrel, a main drying air duct, a ventilation pipe air duct and a connecting air duct;

[0043] The laundry treatment tub includes an inner drum 3 and an outer drum 2, and an air inlet for air to flow into the inner drum 3. The outer drum 2 is provided with a first air outlet. The main drying air duct is connected between the air inlet and the first air outlet. The main drying air duct, the outer drum 2, and the inner drum 3 form a drying air path that can provide a circulation flow of drying air.

[0044] The main drying air duct includes a first condensing air duct 4 provided at the rear of the outer cylinder;

[0045] One end of the ventilation pipe duct 8 is connected to the outer drum 2 of the clothing processing device and communicates with the outer drum 2 of the clothing processing device, and the other end forms a port that communicates with the external air of the clothing processing device;

[0046] The first end of the connecting air duct 10 is connected to the ventilation pipe duct 8, and the second end of the connecting air duct 10 is connected to the first condensing air duct 4 of the clothes processing device, so that the gas in the ventilation pipe duct 8 can enter the first condensing air duct 4 through the connecting air duct 10;

[0047] A cooler is installed on the ventilation pipe duct 8, and the cooler is used to cool the gas in the ventilation pipe duct 8;

[0048] The connecting air duct 10 is provided with a second fan 11 to provide power for the gas in the connecting air duct 10 to flow to the first condensing air duct 4;

[0049] The main drying air duct is provided with a first fan 6 to provide power for the drying air flow to flow in the drying air duct.

[0050] In one embodiment, the air inlet may be provided at the door seal of the clothing processing apparatus, or may be provided on the inner drum 3, which is not specifically limited in this embodiment.

[0051] For ease of understanding, to balance the internal air pressure, a laundry treatment device is equipped with an exhaust device for discharging internal air to the outside world. As the laundry treatment device dries clothes, the internal air of the laundry treatment device is frequently discharged to the outside world through the exhaust device, reducing the total amount of air used to dry the clothes in the laundry treatment device. Furthermore, even if the total amount of internal air remains constant, the air in the laundry treatment device is prone to odor as the drying time increases, which affects the odor of the clothes and reduces the drying effect.

[0052] To improve drying efficiency and results, in one embodiment, a connecting air duct 10 is provided, wherein a first end of the connecting air duct 10 communicates with the ventilation duct 8. The ventilation duct 8 is the original exhaust structure of the clothes processing device and is provided between the outer drum 2 and the fresh air outlet 12, wherein the fresh air outlet 12 is the outlet connecting the interior of the clothes processing device with the outside world.

[0053] The second end of the connecting air duct 10 is communicated with the first condensing air duct 4 of the clothes processing device. The first condensing air duct 4 is a channel for condensing hot and humid gas when the clothes processing device dries clothes, and is usually opened inside the clothes processing device.

[0054] Specifically, the communication position between the connecting air duct 10 and the ventilation pipe duct 8 is located between the cooler and the port where the ventilation pipe duct 8 communicates with the external air.

[0055] In one embodiment, if Figure 2 As shown, because the first end of the connecting air duct 10 is connected to the ventilation duct 8, and the ventilation duct 8 is connected to the fresh air outlet 12 of the clothes processing device, three vents are formed at the first end of the connecting air duct 10. The first vent is the fresh air outlet 12. After entering the first vent, the air is discharged from the fresh air outlet 12 to the outside of the clothes processing device; the second vent is the first end of the connecting air duct 10. After entering the second vent, the air enters the connecting air duct 10; and the third vent is the ventilation duct 8. The air usually moves from the third vent to the third vent.

[0056] Installing a cooler on the ventilation duct 8 cools the air in the ventilation duct 8 before it reaches the three vents, converting it from hot and humid gas to low-temperature gas. Discharging the low-temperature gas to the outside world through the fresh air outlet 12 helps reduce pollution to the outside air, protects the environment, and reduces the emission of hot and humid gas. Discharging the low-temperature gas from the connecting duct 10 to the first condensation duct 4 increases the total amount of air in the first condensation duct 4 while not significantly affecting the temperature of the original air in the first condensation duct 4, facilitating the drying of clothes without affecting the drying effect.

[0057] In one embodiment, a second fan 11 is installed on the connecting air duct 10, so that when fresh air needs to be introduced into the first condensing air duct 4, the second fan 11 is turned on to increase the total amount of gas entering the connecting air duct 10, thereby increasing the total amount of gas entering the first condensing air duct 4, so that the total amount of gas used to dry clothes is sufficient, thereby improving the drying efficiency.

[0058] Through the above content, during the process of gas discharge from the clothing processing equipment, a part of the discharged gas will enter the connecting air duct 10, and then enter the first condensing air duct 4 of the clothing processing equipment through the connecting air duct 10, so that the gas in the first condensing air duct 4 can be replenished, and the amount of gas for clothing processing is sufficient, thereby improving the drying efficiency of clothes when drying.

[0059] In another embodiment of the present application, Figure 3 As shown, the cooler forms a cooling tower water box structure, which includes a box body, an air inlet 9.1 is provided on one side of the box body, and an exhaust port 9.4 is provided on the other side opposite to the air inlet 9.1; a condensate inlet pipe 9.2 is installed in the box body, and at least one water outlet 9.2.1 is provided on the condensate inlet pipe 9.2; at least one drain pipe is installed in the box body, and a drain pipe is provided with a drain port 9.3 opposite to the water outlet 9.2.1.

[0060] It should be noted that the cooling tower water box structure, i.e., the cooling tower water box 9, refers to a device that utilizes the water cooling principle to cool the gas in the air duct 8. In this embodiment, the cooling tower water box 9 is preferred, which helps to improve the cooling efficiency.

[0061] For ease of understanding, Figure 3 For example, condensate inlet pipe 9.2 is located above the box body, with outlet 9.2.1 facing downward. All drain pipes are located below condensate inlet pipe 9.2, allowing them to receive the water discharged from outlet 9.2.1. Drain outlet 9.3 on the drain pipe is oriented opposite to outlet 9.2.1, allowing the water received by the drain pipe to be discharged. The gas in the vent duct 8 passes through the box body and contacts the water, exchanging heat and lowering the gas temperature.

[0062] Through the above content, the cooling tower water box 9 has a simple structure, is easy to install, has high cooling efficiency, and is easy to ensure that the temperature of the gas discharged to the outside or returned to the cooling pipe is low, which is environmentally friendly and helps to improve drying efficiency.

[0063] In another embodiment of the present application, the connecting air duct 10 is provided with a first control valve, and the ventilation pipe duct 8 is provided with a second control valve.

[0064] In one embodiment, the first control valve has the function of blocking the connecting air duct 10. This embodiment does not limit the specific structure of the first control valve, as long as the first control valve can block the connecting air duct 10 when it is in the closed state. Blocking the connecting air duct 10 means that the gas in the ventilation duct 8 or the outside world cannot enter the first condensing air duct 4 through the connecting air duct 10.

[0065] Similarly, the second control valve can block the air duct of the ventilation pipe when closed.

[0066] Through the above content, when the first control valve is closed, it can block the connecting air duct 10, so that when the clothing processing equipment needs to discharge gas to the outside, the discharged gas will not re-enter the interior of the clothing processing equipment from the connecting air duct 10, thereby ensuring the efficiency of the clothing processing equipment in discharging gas to the outside.

[0067] In another embodiment of the present application, along the flow direction of the drying airflow of the main drying air duct, the connection position between the connecting air duct 10 and the first condensing air duct 4 is downstream of the connection position between the first air outlet of the outer cylinder 2 and the connecting air duct 10.

[0068] The first condensation duct 4 has a certain length. The first condensation duct 4 is divided into two parts according to the length of the first condensation duct 4. The first condensation duct 4 can be divided into an upstream part and a downstream part according to the flow direction of the gas in the first condensation duct 4. Specifically, the gas in the first condensation duct 4 first passes through the upstream part and then passes through the downstream part.

[0069] Through the above content, the second end of the connecting air duct 10 is located downstream of the first condensation air duct 4, so that after the gas in the connecting air duct 10 enters the first condensation air duct 4, it is not easy to affect the condensation effect of the original gas in the first condensation air duct 4, thereby ensuring the condensation effect of the gas in the clothing processing equipment, thereby ensuring the drying effect.

[0070] For ease of understanding, Figure 4 As shown, during the washing or early drying phases of the laundry processing apparatus, the air in the inner drum 3 circulates within the apparatus through the first condensing duct 4. Simultaneously, some of the air in the apparatus is discharged to the outside through the outer drum 2 and the ventilation duct 8, thereby balancing the air pressure within the apparatus. At this time, the second fan 11 is off, blocking the connecting duct 10 and preventing air from entering the first condensing duct 4. Meanwhile, the air in the ventilation duct 8 is cooled by the cooling tower water box 9 before reaching the outside.

[0071] like Figure 5As shown, during the drying phase or the later stage of the drying phase of the clothes processing apparatus, the second fan 11 is controlled to be turned on, thereby opening the connecting air duct 10. The air passing through the cooling tower water box 9 is reintroduced into the connecting air duct 10 by the second fan 11, enters the cooling air duct, and participates in the subsequent drying process, thereby increasing the total amount of air used to dry the clothes and improving the drying efficiency.

[0072] In another embodiment of the present application, the main drying duct further includes a heating duct, and the clothing processing equipment further includes a heating device, which is arranged on the heating duct and is used to heat the drying gas condensed by the first condensing duct 4.
