Description

Technical Field

[0001] The present invention belongs to the technical field of washing and drying clothes, and in particular relates to a condensing air duct and a drying program control method of clothes processing equipment. Background Art

[0002] Existing clothing processing equipment with drying function usually heats the clothes through circulating air, and the hot air takes away the moisture in the clothes to dry the clothes. In order to realize the circulation of dry air, the clothing processing equipment is provided with a circulating air duct for condensing and reheating the circulating air and sending the circulating air back to the drum. However, when the clothing processing equipment executes the drying program, the temperature in the air duct keeps changing as the drying program proceeds. When the temperature is high, the circulating air duct may not be able to fully condense the circulating air, resulting in a poor drying effect.

[0003] In order to solve the above problems, the Chinese invention patent with application number CN201610146002.0 discloses a clothing processing device, which adds an auxiliary air duct to the circulating air duct, the air inlet of the auxiliary air duct is located between the condenser and the circulating air outlet, and the air outlet is located between the evaporator and the circulating air inlet, and a baffle assembly is provided at the air inlet. The opening and closing degree of the baffle assembly can be adjusted to control the air volume entering the auxiliary air duct, thereby adjusting the air temperature at the air inlet end of the evaporator to make the system reach the optimal state; although the above scheme controls the air temperature at the air inlet end of the evaporator through the auxiliary air duct, it actually sends the airflow that is about to enter the evaporator for condensation back to the front of the condenser, reducing the flow rate of the air entering the evaporator and reducing the circulation efficiency of the circulating air.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a condensation air duct to address the problems in the above-mentioned prior art. By arranging an auxiliary condensation air duct connected to the condensation air duct outside the condensation air duct, the circulating air is diverted and condensed separately, thereby reducing the working pressure of the condensation device in the condensation air duct and improving the condensation effect.

[0006] Another aspect of the present invention provides a method for controlling the drying program of a clothing processing device, which selects a suitable time in the drying program to open and control the auxiliary cooling air duct and the auxiliary condensing air duct for condensation, thereby reducing the condensation power consumption of the condensing air duct while maintaining the normal operation of the drying program.

[0007] In order to achieve the above-mentioned object, the present invention provides a condensing air duct in a first aspect, comprising a main air duct, wherein the main air duct is provided with an air inlet, a condensing device, a heating device and an air outlet arranged in sequence along the air outlet direction, and further comprising:

[0008] Auxiliary cooling air duct, which is equipped with a heat exchange device to divert and exchange heat between the circulating air;

[0009] The auxiliary cooling air duct has an air inlet end and an air outlet end, and the air inlet end and the air outlet end are respectively communicated with the interior of the main air duct.

[0010] The above solution assists condensation by using the auxiliary cooling air duct connected to the main air duct, thereby improving the heat exchange efficiency of the condensing air duct.

[0011] Furthermore, the air inlet end of the auxiliary cooling air duct is connected between the air inlet and the condensing device, and the air outlet end is connected between the condensing device and the heating device.

[0012] The above scheme diverts the hot and humid air entering the condensing device, and exchanges heat in the main air duct and the auxiliary cooling air duct respectively. The air condensed through the auxiliary cooling air duct returns to the main air duct, is mixed with the circulating air that has exchanged heat through the main air duct, and then enters the heating device for heating, thereby improving the heat exchange efficiency without reducing the circulation efficiency of the main air duct.

[0013] Furthermore, the position of the air inlet end is higher than the position of the air outlet end, and the auxiliary cooling air duct extends downward from the air inlet end to the air outlet end.

[0014] Furthermore, the auxiliary cooling air duct extends downward from the air inlet end to below the air outlet end, and then extends upward to the air outlet end, and a drain outlet is provided at the lowest point of the auxiliary cooling air duct.

[0015] In the above solution, the condensed water condensed in the auxiliary cooling air duct is discharged through the drain port to prevent the condensed water from accumulating in the auxiliary cooling air duct or returning to the main air duct along the auxiliary cooling air duct to affect the heat exchange effect.

[0016] Furthermore, the heat exchange device includes:

[0017] The condensing fins are staggered along the air outlet direction of the auxiliary cooling air duct and arranged on two opposite side walls of the auxiliary cooling air duct.

[0018] In the above solution, the condensing fins have a large heat exchange area and a high heat exchange efficiency. By arranging multiple condensing fins along the air outlet direction of the auxiliary cooling air duct, sufficient heat exchange of the circulating air entering the auxiliary cooling air duct is achieved.

[0019] Furthermore, the condensing fins are tilted in a direction opposite to the air outlet direction.

[0020] The above arrangement further increases the contact area and contact time between the circulating air entering the air outlet duct and the condensing fins, further improving the heat exchange efficiency.

[0021] Furthermore, the heat exchange device also includes at least one of a heat pump system, an air cooling device, and a water cooling device.

[0022] The above solution further improves the heat exchange capacity of the auxiliary cooling air duct and improves the overall heat exchange capacity of the condensing air duct.

[0023] Furthermore, the auxiliary cooling air duct further includes:

[0024] A baffle covers the air inlet end of the auxiliary cooling air duct and is used to control the opening and closing state of the air inlet end.

[0025] Furthermore, when the air inlet end is opened, the baffle is inclined toward the inside of the main air duct, forming a guiding structure for introducing the circulating air into the auxiliary cooling air duct.

[0026] The above scheme controls whether the circulating air enters the auxiliary cooling air duct through the baffle. When the moisture content in the circulating air is low, the auxiliary cooling air duct is not opened, thereby reducing the power consumption of the condensing air duct; when the moisture content in the circulating air is high, the auxiliary cooling air duct is opened to assist in condensation, thereby improving the heat exchange capacity of the condensing air duct.

[0027] At the same time, the baffle is inclined toward the main air duct to form a guiding structure for introducing the circulating air into the auxiliary cooling air duct, thereby avoiding obstruction of the circulating air and affecting the normal flow of the circulating air in the condensing air duct.

[0028] Furthermore, a lint filter device is provided in the main air duct near the air inlet, and the air inlet end of the auxiliary cooling air duct is provided between the lint filter device and the condensing device, thereby preventing lint from clogging the auxiliary cooling air duct or getting stuck in the baffle and affecting the normal closing of the baffle.

[0029] A second aspect of the present invention provides a method for controlling a drying program of a clothes processing device. The clothes processing device includes a computer board and the condensing air duct described in the above solution. The control method includes the following steps:

[0030] S1. The computer board determines that the moisture content of the circulating air in the condensing air duct exceeds the condensing capacity of the main air duct, and opens the auxiliary cooling air duct;

[0031] S2. Close the auxiliary cooling air duct.

[0032] The above scheme opens the auxiliary cooling air duct when it is determined that the moisture content in the circulating air exceeds the condensing capacity range of the main air duct, and diverts the circulating air for heat exchange, thereby reducing the heat exchange pressure of the main air duct, improving the heat exchange efficiency of the condensing air duct, and improving the energy-saving effect of the clothing processing equipment.

[0033] Furthermore, in step S1, the clothing processing device detects the temperature at the air inlet and outlet of the air duct in real time, or the computer board uses the temperature difference between the air inlet and outlet as a detection value, compares the detection value with a preset temperature threshold, determines whether the moisture content of the circulating air in the condensing air duct exceeds the condensing capacity range of the main air duct, and controls the opening and closing state of the auxiliary cooling air duct based on the determination result. Specifically, when the detection value is greater than the temperature threshold, the computer board determines that the moisture content of the circulating air exceeds the condensing capacity range of the main air duct and opens the auxiliary cooling air duct; when the detection value is less than the temperature threshold, the computer board determines that the moisture content of the circulating air does not exceed the condensing capacity range of the main air duct and closes the auxiliary cooling air duct.

[0034] Alternatively, as an alternative to the above solution, the clothing processing equipment records the running time of the drying program in real time to obtain a detection value, compares the detection value with a preset time threshold, and determines whether the moisture content in the circulating air exceeds the condensing capacity range of the main air duct based on the comparison result, and controls the opening and closing state of the auxiliary cooling air duct based on the judgment result.

[0035] Specifically, when the detection value is greater than the time threshold, it is judged that the moisture content in the circulating air exceeds the condensation capacity range of the main air duct, and the auxiliary cooling air duct is opened; when the drying program ends, the auxiliary cooling air duct is closed.

[0036] In addition, a humidity threshold is preset in the computer board. The humidity of the circulating air is detected by the sensor to obtain a detection value. The computer board compares the detection value with the preset humidity threshold, and determines whether the moisture content in the circulating air exceeds the condensing capacity range of the main air duct based on the comparison result. The opening and closing status of the auxiliary cooling air duct is controlled based on the judgment result.

[0037] Furthermore, in the above solution, when the computer board determines that the moisture content in the circulating air exceeds the condensing capacity range of the main air duct, it controls the auxiliary cooling air duct to be opened intermittently.

[0038] The beneficial effects of the present invention are:

[0039] The hot and humid air entering the condensing device is divided and cooled in the main air duct and the auxiliary cooling duct respectively, thereby reducing the working pressure of the condensing device in the main air duct, and the air condensed through the auxiliary cooling duct returns to the main air duct, is mixed with the air in the main air duct and enters the heating device for heating, thereby improving the cooling efficiency without reducing the circulation efficiency of the main air duct; the auxiliary cooling duct extends downward from the air inlet end to below the air outlet end, and then extends upward to the air outlet end; a drain port is provided at the lowest point of the auxiliary cooling duct, which guides the condensed water to flow to the drain port for discharge while condensing the circulating air, thereby avoiding condensed water in the auxiliary cooling duct The cooling fan also prevents condensation in the auxiliary cooling duct from returning to the main cooling duct along the cooling duct and affecting the condensation effect. The condensing fins have a larger heat exchange area and a higher heat exchange efficiency. The condensing fins are arranged along the air outlet direction of the auxiliary cooling duct to achieve sufficient cooling of the circulating air. The air inlet end of the auxiliary cooling duct is provided with a baffle for controlling the opening and closing state of the air inlet end. When the air inlet end is closed, the power consumption of the condensing duct is reduced. When the air inlet end is opened, the condensing duct has a higher heat exchange capacity. The computer board determines whether the moisture content in the circulating air exceeds the condensation capacity range of the main air duct, and controls the opening and closing state of the air inlet end according to the judgment result, thereby improving the energy-saving effect of the clothing processing equipment.

Therefore, they cannot be understood as limiting the present invention.

[0048] Example 1

[0049] As an embodiment of the present invention, this embodiment provides a condensing air duct, including a main air duct and an auxiliary cooling air duct 3, the air inlet end 31 and the air outlet end 32 of the auxiliary cooling air duct 3 are respectively connected to the main air duct, and the main air duct is provided with an air inlet 1, a condensing device 4, a heating device 5 and an air outlet 2 in sequence along the air outlet direction, a heat exchange device 33 is provided in the auxiliary cooling air duct 3, and a fan 6 is also provided in the main air duct, and the fan 6 sends the circulating air to the air outlet 2.

[0050] In this embodiment, the structure of the condensation air duct is as follows: Figure 1 As shown, the air inlet end 31 of the auxiliary cooling duct 3 is connected between the air inlet 1 and the condensing device 4, and the air outlet end 32 is connected between the condensing device 4 and the heating device 5. The circulating air entering the main air duct from the air inlet 1 is diverted by the air inlet end 31 of the auxiliary cooling duct 3 before entering the condensing device 4, and condensation heat exchange is performed in the main air duct and the auxiliary cooling duct 3 respectively. The circulating air that has exchanged heat in the auxiliary cooling duct 3 returns to the main air duct from the air outlet end 32 of the auxiliary cooling duct 3, and is mixed with the circulating air that has exchanged heat in the main air duct and then enters the heating device 5 for heating, thereby improving the heat exchange efficiency of the condensing air duct without reducing the circulation efficiency of the main air duct.

[0051] Furthermore, the position of the air inlet end 31 is higher than the position of the air outlet end 32. The auxiliary cooling air duct 3 extends downward from the air inlet end 31 to below the air outlet end 32, and then extends upward to the air outlet end 32. A drainage outlet is provided at the lowest point of the auxiliary cooling air duct 3.

[0052] In the above scheme, after the auxiliary cooling duct 3 exchanges heat with the circulating air, the condensed water flows along the auxiliary cooling duct 3 to the lowest point and is discharged from the drain outlet, thereby avoiding the accumulation of condensed water in the auxiliary cooling duct 3 and also avoiding the condensed water returning to the main air duct along the auxiliary cooling duct 3 to affect the heat exchange effect of the main air duct.

[0053] Furthermore, condensing fins are provided in the auxiliary cooling air duct 3. The condensing fins are staggered on two opposite side walls of the auxiliary cooling air duct 3 along the air outlet direction of the auxiliary cooling air duct 3. The condensing fins are tilted in the direction opposite to the air outlet direction.

[0054] The condensing fins have a large heat exchange area. Multiple condensing fins are arranged along the air outlet direction in the auxiliary cooling air duct 3, which improves the heat exchange efficiency of the auxiliary cooling air duct 3. The condensing fins are inclined in the direction opposite to the air outlet direction. The circulating air entering the auxiliary cooling air duct 3 has a longer contact time with the condensing fins, and can perform heat exchange more fully.

[0055] Further, such as Figure 2 The heat exchange device 33 shown also includes at least one of a heat pump system, an air cooling device, and a water cooling device.

[0056] The above solution avoids the problem that the heat exchange capacity of the condensing fins is insufficient and cannot fully exchange heat with the circulating air entering the air outlet duct, thereby further improving the heat exchange capacity of the air outlet duct.

[0057] Further, such as Figure 4 As shown, the auxiliary cooling air duct 3 also includes:

[0058] a baffle 311 covering the air inlet end 31 of the auxiliary cooling air duct 3 and used to control the opening and closing state of the air inlet end 31;

[0059] When the air inlet end 31 is opened, the baffle 311 is inclined toward the inside of the main air duct, forming a guiding structure for introducing the circulating air into the auxiliary cooling air duct 3 .

[0060] Furthermore, the above scheme controls whether the circulating air enters the auxiliary cooling air duct 3 through the baffle 311. When there is less moisture in the circulating air, the auxiliary cooling air duct 3 is not opened, thereby reducing the power consumption of the condensing air duct; when there is more moisture in the circulating air, the auxiliary cooling air duct 3 is opened to assist in condensation, thereby improving the heat exchange capacity of the condensing air duct. At the same time, the baffle 311 is tilted toward the main air duct to form a guiding structure for introducing the circulating air into the auxiliary cooling air duct 3, thereby avoiding obstruction to the circulating air and affecting the normal flow of the circulating air in the condensing air duct.

[0061] Furthermore, a lint filter device is provided in the main air duct near the air inlet 1, and the air inlet end 31 of the auxiliary cooling air duct 3 is provided between the lint filter device and the condensing device 4, thereby preventing lint from clogging the auxiliary cooling air duct 3 or getting stuck in the baffle 311 and affecting the normal closure of the baffle 311.

[0062] Example 2

[0063] As another embodiment of the present invention, this embodiment provides a condensation air duct having the same structure as the first embodiment, except that: Figure 2As shown, a heat pump system is provided on the main air duct, the condensing device 4 is a first evaporator, and the heating device 5 is a condenser.

[0064] In this embodiment, after the circulating air enters the main air duct from the air inlet 1, it exchanges heat through the first evaporator to condense moisture, and then is heated by the condenser to obtain hot circulating air, which is discharged from the air outlet 2 along the main air duct.

[0065] Furthermore, the air inlet end 31 of the auxiliary cooling air duct 3 is located between the air inlet 1 and the first evaporator, and the air outlet end 32 of the auxiliary cooling air duct 3 is located between the first evaporator and the condenser.

[0066] Furthermore, the heat exchange device 33 on the auxiliary cooling air duct 3 includes condensing fins and a second evaporator. The condensing fins are staggered on two opposite side walls of the auxiliary cooling air duct 3 along the air outlet direction of the auxiliary cooling air duct 3, and the condensing fins are tilted in the direction opposite to the air outlet direction.

[0067] The second evaporator is arranged in the auxiliary cooling air duct 3. When the circulating air enters the auxiliary cooling air duct 3, heat exchange is performed between the second evaporator and the circulating air. Then the second evaporator transfers the displaced heat to the condenser, thereby improving the heating efficiency of the condenser in the main air duct, reducing the power consumption of the condensing air duct, and achieving energy-saving effects.

[0068] Example 3

[0069] As another embodiment of the present invention, this embodiment provides a condensing air duct having the same structure as that of the first embodiment, except that the heat exchange device 33 is a water-cooled heat exchanger, and the heat exchange pipe of the water-cooled heat exchanger extends into the auxiliary cooling air duct 3 to exchange heat with the circulating air.

[0070] In this embodiment, if Figure 3 The heat exchange tubes of the water-cooled heat exchanger are arranged perpendicular to the air outlet direction of the auxiliary cooling air duct 3, and an air path for circulating air to pass through is formed between two adjacent heat exchange tubes.

[0071] In the above manner, since water has a high specific heat capacity, the water-cooled heat exchanger can always maintain a good heat exchange effect when the auxiliary cooling air duct 3 runs for a long time, thereby improving the versatility of the auxiliary cooling air duct 3 in different working states.

[0072] Furthermore, the water used for heat exchange in the water-cooled heat exchanger can be reused. Since the water after heat exchange has a certain temperature, it can be used for washing clothes or other clothing processing steps, thereby saving water resources.

[0073] Example 4

[0074] As another embodiment of the present invention, this embodiment provides a condensing air duct having the same structure as that of the third embodiment, except that the heat exchange device 33 is an air-cooled heat exchanger.

[0075] In this embodiment, the arrangement of the air-cooled heat exchanger is the same as that of the third embodiment.

[0076] The present invention also provides a method for controlling a drying program of a clothes processing device 7, wherein the clothes processing device 7 includes a computer board and the condensing air duct described in the above scheme, specifically:

[0077] Example 5

[0078] As another embodiment of the present invention, this embodiment provides a method for controlling a drying program of a clothes processing device, wherein the clothes processing device 7 has a condensing air duct as described in the first embodiment, and the method for controlling a drying program includes the following steps:

[0079] S1, the computer board determines that the moisture content of the circulating air in the condensing air duct exceeds the condensing capacity range of the main air duct, and opens the auxiliary cooling air duct 3;

[0080] S2. Close the auxiliary cooling air duct 3.

[0081] In this embodiment, the judgment method of step S1 is: the clothing processing equipment detects the temperature at the air inlet and outlet of the air duct in real time, the computer board takes the temperature difference at the air inlet and outlet as the detection value, compares the detection value with the preset temperature threshold and judges whether the moisture content in the circulating air in the condensation air duct exceeds the condensation capacity range of the main air duct, and controls the opening and closing state of the auxiliary cooling air duct according to the judgment result.

[0082] The specific judgment method is: when the detection value is greater than the temperature threshold, the computer board determines that the moisture content in the circulating air exceeds the condensing capacity range of the main air duct, and opens the auxiliary cooling air duct 3; when the detection value is less than the temperature threshold, the computer board determines that the moisture content in the circulating air does not exceed the condensing capacity range of the main air duct, and closes the auxiliary cooling air duct 3.

[0083] The above scheme opens the auxiliary cooling air duct 3 when it determines that the moisture content in the circulating air exceeds the condensing capacity range of the main air duct, and diverts the circulating air for heat exchange, thereby reducing the heat exchange pressure of the main air duct, improving the heat exchange efficiency of the condensing air duct, and improving the energy-saving effect of the clothing processing equipment 7.

[0084] In the drying process, the clothing processing equipment is in the heating stage at the initial stage of drying. At this time, the clothes are not fully heated, and the circulating air contains only a small amount of moisture. The main air duct can complete the heat exchange independently; in the middle stage of drying, the moisture in the clothes is quickly carried away by the circulating air at high temperature. At this time, the moisture content in the circulating air is very high, but because the clothes absorb more heat from the circulating air, the temperature in the clothing processing equipment has not reached the highest level. When the computer board determines that the detection value is greater than the temperature threshold, the computer board determines that the moisture content in the circulating air exceeds the condensing capacity range of the main air duct, and opens the auxiliary cooling air duct 3; in the later stage of drying, there is only a small amount of moisture left in the clothes, which can only absorb a small amount of heat from the circulating air. Therefore, at this time, the temperature in the clothing processing equipment reaches the highest level, and the moisture content in the circulating air is lower than that in the middle stage of drying. When the computer board determines that the detection value is less than the temperature threshold, the computer board determines that the moisture content in the circulating air does not exceed the condensing capacity range of the main air duct, and closes the auxiliary cooling air duct 3.

[0085] Alternatively, as an alternative to the above solution, the auxiliary cooling air duct 3 is opened and remains open until the drying process is completed.

[0086] Furthermore, in the above scheme, when the computer board determines that the moisture content in the circulating air exceeds the condensing capacity range of the main air duct, the auxiliary cooling air duct is controlled to be opened intermittently. For example, after the computer board controls the auxiliary cooling air duct to be opened for 5 minutes, it controls the auxiliary cooling air duct to be closed for 10 minutes, and then controls the auxiliary cooling air duct to be opened for 5 minutes.

[0087] The above solution prevents the auxiliary cooling air duct from being opened for a long time, and the temperature in the auxiliary cooling air duct is too high to effectively exchange heat for the circulating air diverted into the auxiliary cooling air duct.

[0088] Example 6

[0089] As another embodiment of the present invention, this embodiment provides a method for controlling a drying program of a clothes processing device, wherein the clothes processing device 7 has a condensing air duct as described in the first embodiment, and the method for controlling a drying program includes the following steps:

[0090] S1, the computer board determines that the moisture content of the circulating air in the condensing air duct exceeds the condensing capacity range of the main air duct, and opens the auxiliary cooling air duct 3;

[0091] S2. Close the auxiliary cooling air duct 3.

[0092] In this embodiment, the judgment method of step S1 is: the computer board records the running time of the drying program in real time to obtain a detection value, compares the detection value with a preset time threshold, and judges whether the moisture content in the circulating air exceeds the condensing capacity range of the main air duct based on the comparison result, and controls the opening and closing state of the auxiliary cooling air duct 3 based on the judgment result.

[0093] The specific judgment method is: when the detection value is greater than the time threshold, it is judged that the moisture content in the circulating air exceeds the condensation capacity range of the main air duct, and the auxiliary cooling air duct 3 is opened; when the drying program is completed, the auxiliary cooling air duct 3 is closed.

[0094] Furthermore, in the above scheme, when the computer board determines that the moisture content in the circulating air exceeds the condensing capacity range of the main air duct, the auxiliary cooling air duct is controlled to be opened intermittently. For example, after the computer board controls the auxiliary cooling air duct to be opened for 10 minutes, it controls the auxiliary cooling air duct to be closed for 20 minutes, and then controls the auxiliary cooling air duct to be opened for 10 minutes.

[0095] The above solution prevents the auxiliary cooling air duct from being opened for a long time, and the temperature in the auxiliary cooling air duct is too high to effectively exchange heat for the circulating air diverted into the auxiliary cooling air duct.

[0096] Example 7

[0097] As another embodiment of the present invention, this embodiment provides a method for controlling a drying program of a clothes processing device, wherein the clothes processing device 7 has a condensing air duct as described in the first embodiment, and the method for controlling a drying program includes the following steps:

[0098] S1, the computer board determines that the moisture content of the circulating air in the condensing air duct exceeds the condensing capacity range of the main air duct, and opens the auxiliary cooling air duct 3;

[0099] S2. Close the auxiliary cooling air duct 3.

[0100] In this embodiment, the judgment method of step S1 is: a humidity threshold is preset in the computer board, and the humidity of the circulating air is detected by the sensor to obtain a detection value. The computer board compares the detection value with the preset humidity threshold, and judges whether the moisture content in the circulating air exceeds the condensing capacity range of the main air duct based on the comparison result, and controls the opening and closing state of the auxiliary cooling air duct based on the judgment result.

[0101] Example 8

[0102] As another embodiment of the present invention, this embodiment provides a drying program control method for a clothing processing device. The steps of the drying program control method are the same as the drying program control method described in Example 5, except that a humidity threshold is preset in the computer board. While judging whether the moisture content in the circulating air exceeds the condensing capacity range of the main air duct based on the difference in temperature at the air inlet and outlet of the condensing air duct and the preset threshold, the humidity of the circulating air is detected by the sensor to obtain a detection value. The computer board compares the detection value with the preset humidity threshold, and judges whether the moisture content in the circulating air exceeds the condensing capacity range of the main air duct based on the comparison result, and controls the opening and closing state of the auxiliary cooling air duct based on the judgment result.
