[0048] At present, the heat pump system is used to heat the gas to dry clothes, which can maintain a low temperature of 50℃-60℃ to dry clothes, minimizing damage to clothes, especially some delicate clothes, and saving energy and being environmentally friendly.

[0049] On the one hand, there are also some problems with simply using a heat pump system to heat and dry clothes. For example, since heat pump drying is an internal circulation method, the cooling time after the clothing load is dried is too long, and the refreshing and odor-removing effect on the clothes is not ideal.

[0050] Based on this, Figure 1-Figure 5 As shown, the laundry processing device according to an embodiment of the present invention comprises: a laundry processing drum 1, the front side of the laundry processing drum 1 is provided with a front air duct, and the rear side of the laundry processing drum 1 is provided with a rear air duct 2;

[0051] The two-device assembly 3 includes a box body and a drying air duct. The box body has a drying air inlet and a drying air outlet 4 connected to the drying air duct, and a fresh air inlet 5 and a fresh air outlet 6 connected to the interior space of the box body;

[0052] The drying air outlet 4 is connected to the inlet of the rear air duct 2, the outlet of the rear air duct 2 is connected to the rear side of the clothes processing drum 1, the front side of the clothes processing drum 1 is connected to the inlet of the front air duct, and the outlet of the front air duct is connected to the drying air inlet, forming a drying circulation air path;

[0053] The fresh air component includes: a fresh air duct 7, a fresh air fan 8 and a fresh air damper 9. The fresh air fan 8 is arranged in the fresh air duct 7. The end of the fresh air duct 7 close to the air inlet side of the fresh air fan 8 is used to communicate with the outside air. The end of the fresh air duct 7 close to the air outlet side of the fresh air fan 8 is connected to the fresh air inlet 5. The fresh air outlet 6 is connected to the front side of the clothing processing drum 1. The rear side of the clothing processing drum 1 is connected to the inlet of the fresh air damper 9. The outlet of the fresh air damper 9 is used to communicate with the outside air.

[0054] Specifically, the clothing processing device can be a heat pump type dryer, which includes a clothing processing drum 1 and a two-device assembly 3. The clothing processing drum 1 accommodates a clothing load, and the two-device assembly 3 processes hot and humid air. The two-device assembly 3 is connected to the clothing processing drum 1 through a drying air duct to form a drying circulation air path. Dry hot air is sent to the rear of the clothing processing drum 1 through the two-device assembly 3. The drying air takes away the moisture in the clothing processing drum 1 to form hot and humid gas, which is discharged from the front of the clothing processing drum 1 back to the two-device assembly 3, and is converted into dry hot air again through the two-device assembly 3, and circulates in sequence to dry the clothes in the clothing processing drum 1.

[0055] The fresh air component can draw air through the fresh air fan 8 to introduce external air from the fresh air duct 7 into the clothing processing drum 1. Introducing fresh air into the clothing processing drum 1 can avoid the situation where only internal air circulates during the heat pump drying process. The fresh air can not only achieve the deodorization function, but also quickly cool down the clothes after the drying is completed, thereby reducing the user's waiting time and improving the user's experience.

[0056] The fresh air duct 7 is first connected to the fresh air inlet 5 and connected to the box body of the two-device assembly 3. The fresh air can be used to cool the interior of the box body. In the later stage of drying, the condenser tube temperature is reduced, so that the temperature of the refrigerant flowing into the evaporator is lower, and the drying medium is better dehumidified.

[0057] Among them, Figure 3 -Attached Figure 5 The direction of the arrow is the direction of fresh air flow.

[0058] According to the clothing processing device of an embodiment of the present invention, a fresh air inlet 5 and a fresh air outlet 6 are added to the box body of the two-device component 3, and the fresh air inlet 5 is connected to the fresh air inlet 5 through the fresh air component, and then connected to the clothing processing drum 1 through the fresh air outlet 6. Fresh air can be introduced into the clothing processing drum 1 through the fresh air component, thereby reducing the cooling time after the clothing load is dried, effectively refreshing and deodorizing the clothing, and the fresh air can also cool the condenser inside the box body by passing through the box body of the two-device component 3. By lowering the condenser tube temperature, the temperature of the refrigerant flowing into the evaporator is lower, thereby better dehumidifying the drying medium.

[0059] In some embodiments, the fresh air assembly further includes: an auxiliary air duct 10, the fresh air outlet 6 is connected to the clothes processing drum 1 through the auxiliary air duct 10, and the auxiliary air duct 10 is used to increase the wind speed of the fresh air;

[0060] Among them, an acceleration fan 11 is provided in the auxiliary air duct 10, and one end of the auxiliary air duct 10 close to the air inlet of the acceleration fan 11 is connected to the outlet of the fresh air channel, and one end of the auxiliary air duct 10 close to the air outlet of the acceleration fan 11 is connected to the front side of the clothing processing drum 1.

[0061] Specifically, an accelerating fan 11 is provided in the auxiliary air duct 10. The accelerating fan 11 can be a centrifugal fan. The auxiliary air duct 10 can introduce the fresh air in the box body of the two-device assembly 3 into the clothing treatment drum 1 through the accelerating fan 11. The speed of the fresh air entering the front side of the clothing treatment drum 1 can be increased by accelerating the fresh air. The direction in which the fresh air enters the clothing treatment drum 1 is opposite to the direction in which the drying air enters the clothing treatment drum 1. The fresh air speed is faster, which not only can make the clothes located at the air inlet of the clothing treatment drum 1 be blown away by the high-speed wind without blocking the fresh air, but also can make the wind in the middle position of the clothing treatment drum 1 flow in a spiral shape, and then with the rotation of the clothing treatment drum 1, the generated high-speed fresh air flow can be used to strongly contact the clothes in the clothing treatment drum 1, so that the clothes and the fresh air can be better contacted to remove odors, and the temperature in the clothing treatment drum 1 can be quickly reduced.

[0062] In some embodiments, the fresh air outlet 6 is located behind the condenser of the two-device assembly 3.

[0063] Specifically, the fresh air outlet 6 of the box body of the two-device component 3, that is, the air inlet of the auxiliary air duct 10, can make the wind speed at the location of the condenser faster by setting the position of the fresh air outlet 6, so that the fresh air in the box body can pass through the condenser, which can better cool the condenser.

[0064] In some embodiments, an air duct adapter is provided at the air outlet of the auxiliary air duct 10, and the outlet of the air duct adapter is in a retracted shape.

[0065] Specifically, the outlet of the air duct adapter is in a convergent shape, that is, the flow area of ​​the air duct adapter gradually decreases from the inlet to the outlet. By reducing the flow area, the wind speed at the air outlet can be further increased, so that the wind speed can be greater than 100m / s, so that the fresh air can have strong contact with the clothes and ensure the fresh air deodorization effect.

[0066] In some embodiments, the laundry processing device further comprises: an outer shell, the laundry processing drum 1 is disposed in the outer shell, a rear side wall is installed on the rear side of the laundry processing drum 1, the rear air duct 2 is buckled on the rear side wall, and is connected to the laundry processing drum 1 through the rear side wall;

[0067] The fresh air duct 7 is connected to the outside air through the rear side wall, and a shutter 13 is provided at the rear side wall corresponding to the air inlet of the fresh air duct 7, or the fresh air duct 7 is connected to the outside air through the side panel of the outer shell.

[0068] Specifically, the fresh air duct 7 can be connected to the outside through the rear side wall to draw in air, or it can be connected to the outside through the side wall of the outer shell to draw in air. The specific details can be determined based on user experience and actual installation requirements. The shutters 13 are set on the rear side wall to provide certain protection for the air inlet, while preventing debris from entering the fresh air duct 7.

[0069] In some embodiments, the fresh air damper 9 includes: a ventilation housing 91, a ventilation grille 92, a motor 93 and a wind shield 94;

[0070] The ventilation grille 92 is arranged at the air outlet of the ventilation shell 91, and the wind shield 94 is connected to the motor 93. The motor 93 can drive the wind shield 94 to move to the air inlet of the ventilation shell 91, blocking the ventilation shell 91 and the clothing processing drum 1, or drive the wind shield 94 to move away from the air inlet of the ventilation shell 91, so that the ventilation shell 91 and the clothing processing drum 1 are connected.

[0071] Specifically, when the clothes processing drum 1 introduces fresh air from the outside, in order to ensure the air pressure balance in the clothes processing drum 1 and to circulate the air normally, the excess air can be discharged through the fresh air damper 9. The fresh air damper 9 can be driven by the motor 93 to drive the wind shield 94 to control the opening and closing, and is protected by the ventilation grille 92 to prevent foreign matter from entering the clothes processing drum 1 through the fresh air damper 9.

[0072] In some embodiments, a controller;

[0073] The controller controls the fresh air fan 8, the accelerating fan 11 and the fresh air damper 9 based on the drying demand.

[0074] Specifically, the controller can control the fresh air fan 8, the acceleration fan 11 and the fresh air damper 9 to adjust the opening and closing of the fresh air duct 7, the auxiliary air duct 10 and the fresh air damper 9.

[0075] In some embodiments, the fresh air blower 8, the accelerating blower 11, and the fresh air damper 9 are controlled based on the drying demand, including:

[0076] If fresh air deodorization is required, determine whether the external air humidity is greater than the first preset value d1. If the external air humidity is not greater than the first preset value d1, turn on the fresh air fan 8, the acceleration fan 11 and the fresh air damper 9;

[0077] If drying and cooling are required, it is determined whether the return air temperature in the drying circulation air path is greater than the second preset value T1. If the return air temperature is greater than the second preset value T1, the fresh air fan 8, the acceleration fan 11 and the fresh air damper 9 are turned on;

[0078] If clothes need to be dried, determine whether the load humidity of the clothes processing drum is greater than the third preset value d2 and whether the condenser tube temperature is greater than the fourth preset value T2. If the load humidity of the clothes processing drum is less than the third preset value d2 and the condenser tube temperature is greater than the fourth preset value T2, turn on the fresh air fan 8 and the fresh air damper 9.

[0079] Specifically, during the operation of the clothes treating device, there may be multiple operating modes.

[0080] Among them, as attached Figure 6 As shown, when it is necessary to deodorize the clothes, the fresh air deodorization program can be run. In the fresh air deodorization program, the humidity of the external air can be obtained through the humidity sensor. When the humidity of the external air is not greater than the first preset value d1, it means that the introduction of external air will not make the clothes in the clothing processing drum 1 moist, and fresh air can be introduced. By turning on the fresh air fan 8, the acceleration fan 11 and the fresh air damper 9, the fresh air circulation can be started, so that the fresh air enters the clothing processing drum 1 and takes away foreign matter on the clothes, and then is discharged from the clothing processing drum 1. The high-speed fresh air generated can achieve a better deodorization effect.

[0081] As attached Figure 7 As shown, when drying and cooling are required, that is, after drying is completed, when the clothes processing drum 1 needs to be cooled, the drying and cooling program can be run, and the return air temperature in the drying circulation air path is obtained through the temperature sensor, that is, the air flow temperature entering the clothes processing drum 1. When the return air temperature is greater than the second preset value T1, it means that the return air temperature is high and needs to be cooled. The fresh air fan 8, the acceleration fan 11 and the fresh air damper 9 can be turned on to quickly take away the heat in the clothes processing drum 1 through the fresh air, thereby achieving the technical effect of rapid cooling.

[0082] As attached Figure 8 As shown, when clothes need to be dried and the drying program is executed, the load humidity of the clothes processing drum can be obtained through the humidity sensor, and the condenser temperature can be obtained through the temperature sensor. When the load humidity of the clothes processing drum is less than the third preset value d2, and the condenser tube temperature is greater than the fourth preset value T2, it means that the drying program is in the later stage, and the fresh air fan 8 and the fresh air damper 9 can be turned on to cool the condenser in the two-device component 3 by the fresh air, reduce the condenser tube temperature, make the temperature of the refrigerant flowing into the evaporator lower, better dehumidify the drying medium, and improve the drying effect in the later stage of drying. Until the load humidity of the clothes processing drum is less than the fourth preset value d3, it means that the drying operation of this stage has been completed, the program ends, and the next stage of cooling and cooling starts to obtain other programs.

[0083] An embodiment of the present application also provides a method for controlling a clothing processing device, including: controlling the introduction of fresh air based on the requirements of an operating program.

[0084] In some embodiments, in response to the fresh air deodorization program, if the outside air humidity is not greater than the first preset value d1, fresh air is introduced for deodorization;

[0085] In response to the drying and cooling program, if the return air temperature is greater than the second preset value T1, fresh air is introduced to cool the clothes processing drum 1;

[0086] In response to the drying process, if the load humidity of the laundry tub is less than a first preset value d1 and the condenser tube temperature is greater than a second preset value T1, fresh air is introduced to cool the condenser.

[0087] Specifically, introducing fresh air in the fresh air deodorization program can remove odors through the fresh air, thereby improving the deodorization effect on clothes. Introducing fresh air in the drying and cooling program can quickly take away the heat in the clothing processing drum 1 through the fresh air, thereby accelerating the cooling. Introducing fresh air in the drying program can lower the condenser tube temperature through the fresh air, thereby better dehumidifying the drying medium.
