Technical Field
[0001] This invention relates to the field of garment processing, and in particular to a garment processing device and control method. Background Technology
[0002] Currently, traditional garment care machines, such as dryers and washer-dryer combos, generally work by heating air with a heater and sending it into the drum. Under the heating effect of the hot air, the water on the clothes evaporates to form humid air, which then enters the condenser. In the condenser, the humid air condenses into water and dry gas after being cooled by a cooling medium. The dry gas is then heated by the heater and enters the drum. This cycle is repeated to achieve the purpose of drying clothes.
[0003] In related technologies, the inlet of the condenser's flow channel is located below the barrel assembly, the air outlet on the outer barrel is generally located at the lower part of the outer barrel, the condenser's condensation outlet is located at the upper part of the outer barrel, and the condenser is located between the upper and lower parts of the outer barrel. The condenser has a large volume and complex structure, and it is easy for lint to accumulate inside the condenser. At the same time, it is difficult to effectively clean the flow channel structure inside the condenser. Summary of the Invention
[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a garment processing device, which includes an outer tub assembly with an air outlet located at the upper part of the outer tub. Simultaneously, the condenser inlet is connected to the air outlet, significantly shortening the distance between the condenser inlet and outlet, reducing the volume of the condenser, and making cleaning of the condensation chamber within the condenser more convenient.
[0005] The present invention also proposes a control method for the above-mentioned garment processing equipment.
[0006] The garment processing device according to the present invention includes: an outer tub assembly, wherein an air outlet is provided on the outer tub assembly and the air outlet is located on the upper part of the outer tub assembly; a condenser, wherein a condensation chamber is formed inside the condenser, and a condensation inlet and a condensation outlet communicating with the condensation chamber are provided on the condenser, wherein the condensation inlet is communicating with the air outlet.
[0007] According to the garment processing equipment of this application, the air outlet is set at the upper part of the outer tub assembly, so that the condenser inlet connected to the air outlet is also set at the upper part of the outer tub assembly, and the condenser outlet of the condenser is also located at the upper part of the outer tub assembly. Accordingly, the volume of the condenser and the capacity of the condensing chamber are further reduced, so that lint does not easily accumulate in the condensing chamber and is easy to clean.
[0008] According to one embodiment of the present invention, the distance between the condenser inlet and the condenser outlet is L, and the radius of the outer barrel assembly is R, wherein L and R satisfy: L≤R.
[0009] According to one embodiment of the present invention, L and R satisfy: 1 / 4R≤L≤R / 2.
[0010] According to one embodiment of the present invention, the garment processing device further includes: a water outlet device disposed within the condensation chamber and adapted to spray cooling water into the condensation chamber.
[0011] According to one embodiment of the present invention, the garment processing equipment further includes: a drying device having a drying tunnel formed therein, and a heating element disposed therein; a fan component having an air-gathering chamber connected to the drying tunnel formed therein, and a fan wheel disposed therein; the fan component further includes a connecting channel connecting the air-gathering chamber and the condenser inlet, the connecting channel extending horizontally. According to one embodiment of the present invention, an inlet pipe communicating with the inlet end of the water outlet device is disposed on the outer side of the condenser housing, the inlet end being located at the lowest end of the water outlet device.
[0012] According to one embodiment of the present invention, the water outlet device extends obliquely from the condenser inlet to the condenser outlet, and there are multiple water outlets on the outer periphery of the water outlet device, and the multiple water outlets are arranged at intervals in the extending direction of the water outlet device.
[0013] According to one embodiment of the present invention, a condensation channel is formed on the inner sidewall of the condensation chamber, the upstream end of the condensation channel is adjacent to the water outlet device, and the downstream end of the condensation channel is adjacent to the condensation outlet.
[0014] According to the control method of the present invention, in step S102, it is determined that the clothing processing equipment is in the washing stage or the drum self-cleaning stage, and the inner drum is controlled to rotate at a preset speed to agitate the washing water and allow the washing water to enter the condensing chamber for cleaning. This enables the clothing processing equipment to have an automatic cleaning function for the condenser, ensuring the service life of the condenser of the clothing processing equipment, and at the same time ensuring that the drying function of the clothing processing equipment always maintains good performance.
[0015] According to one embodiment of the present invention, before determining that the garment processing equipment is in the washing stage or the drum self-cleaning stage and controlling the inner drum to rotate at a preset speed, the method further includes: S202, determining that the garment processing equipment has started washing or the drum self-cleaning stage, and injecting water into the garment processing equipment.
[0016] According to one embodiment of the present invention, controlling the inner tub to rotate at a preset speed includes:
[0017] S204. Ensure that the parameters of the laundry equipment during the washing or drum self-cleaning process meet the preset conditions, and close the drainage channel.
[0018] S206. During the first preset time of the washing stage or the drum self-cleaning stage, the inner drum is controlled to rotate at a preset speed; the first preset time is less than or equal to the total duration of the washing stage or the drum self-cleaning stage.
[0019] S208. Determine that the inner tub rotates at a preset speed for a first preset time, then stop the inner tub from rotating and drain the water.
[0020] According to one embodiment of the present invention, the preset rotation speed of the inner tub is 100-250 rpm.
[0021] According to one embodiment of the present invention, the preset rotation speed of the inner tub is 180 rpm to 220 rpm.
[0022] According to one embodiment of the present invention, the parameters include at least one of the following: the number of times water is introduced or drained, the number of times water is rinsed, the turbidity value of the water in the outer tub assembly, and the number of times water in the outer tub assembly is circulated and filtered. The preset conditions include at least one of the following: the number of times water is introduced or drained reaches a preset number, the number of times water is rinsed reaches a preset number, the turbidity value of the water in the outer tub assembly is less than a preset threshold, and the number of times water in the outer tub assembly is circulated and filtered reaches a preset number.
[0023] In summary, the garment processing equipment of the present invention addresses the problem in the prior art where impurities easily accumulate in the turbulence structure inside the condensing chamber, making it difficult to clean the condensing chamber. By placing the air outlet of the outer tub assembly at the upper part of the outer tub assembly, connecting the condensing inlet to the air outlet, and placing the condensing outlet at the upper part of the outer tub assembly, the distance between the condensing inlet and the condensing outlet is reduced, thereby shortening the length of the condensing chamber in the condenser. The cleaning water can enter the condensing chamber under the agitation of the inner tub to flush the inner wall of the condensing chamber, thus greatly reducing the difficulty of cleaning the condensing chamber.
[0024] Furthermore, compared to existing technologies, this application can utilize the rotation of the inner tub to clean the condenser chamber, enabling the garment processing equipment to have a self-cleaning function for the condenser chamber, reducing the difficulty for users to clean the condenser, and enriching the functions of the garment processing equipment.

[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0045] The following is for reference. Figures 3-7 A condenser 2 according to an embodiment of the present invention is described.
[0046] The condenser 2 according to the present invention includes a condenser shell 21 and a water outlet device 22. A condensation chamber 210 is formed inside the condenser shell 21, and the water outlet device 22 is disposed inside the condensation chamber 210. The water outlet device 22 is adapted to spray cooling water into the condensation chamber 210.
[0047] The condensing chamber 210 formed inside the condenser shell 21 is suitable for condensing high-temperature and humid gas. When the high-temperature and humid gas flows through the condensing chamber 210, the temperature inside the condensing chamber 210 is low, and heat exchange occurs with the high-temperature and humid gas, so that the high-temperature and humid gas condenses inside the condensing chamber 210 to dehumidify the high-temperature and humid gas and form a low-temperature and dry gas.
[0048] In related technologies, a condenser typically includes a cooling water inlet channel and an airflow channel. The airflow channel inlet is located below the tank assembly, and the airflow channel in the condensation chamber extends from the bottom to the top of the tank assembly. Cooling water is introduced into the condensation chamber through a condensation pipe, where it encounters the humid, hot gas entering the condensation channel, resulting in intense heat exchange and condensation of the humid, hot gas. In this technology, the cooling water typically flows downwards within the condensation chamber due to gravity, exchanging heat with the upward-flowing humid, hot gas within a limited area. The small contact area and short contact time between the cooling water and the humid, hot air in the heat exchange area lead to low heat exchange efficiency. While some existing technologies incorporate baffles or other structures within the condensation chamber to increase the exchange efficiency between the cooling water and the humid, hot air, this can cause impurities such as lint from the humid, hot gas to accumulate at these baffles or other structures, leading to blockages within the condensation chamber and further reducing condensation and drying efficiency.
[0049] According to the condenser 2 of this application, a water outlet device 22 is installed inside the condensation chamber 210, and cooling water is sprayed into the condensation chamber 210 using the water outlet device 22. The cooling water sprayed by the water outlet device 22 can come from the outside. The low-temperature cooling water from the outside is sprayed into the condensation chamber 210 through the water outlet device 22 to quickly reduce the temperature of the airflow flowing through the condensation chamber 210. This can reduce the temperature inside the condensation chamber 210 to the dew point of the hot and humid airflow, so as to quickly condense the moisture in the hot and humid airflow and achieve the purpose of dehumidifying the hot and humid airflow.
[0050] like Figure 5 As shown, instead of using an external condensate conduit, a water outlet device 22 is installed inside the condensation chamber 210. This extends the flow path of the cooling water, allowing for customized structures for both the condensation chamber 210 and the water outlet device 22. This application eliminates the need for additional baffles, flow channels, or other limiting structures inside the condensation chamber 210. The water outlet device 22 alone is sufficient to achieve cooling of hot and humid air, increasing airflow velocity and reducing airflow attenuation.
[0051] According to the condenser 2 of the present invention, by setting the water outlet device 22 in the condensation chamber 210 and spraying cooling water into the condensation chamber 210 using the water outlet device 22, the contact area and contact time between the cooling water and the hot and humid gas in the condensation chamber 210 are increased, thereby improving the condensation effect of the condenser 2 in the garment processing equipment 1. This application does not require the setting of a turbulence structure, reduces the attenuation of the airflow velocity by the condenser 2, and also reduces the possibility of lint accumulation, thereby improving the drying effect of the garment processing equipment 1.
[0052] It should be noted that this application improves the condensation and dehumidification effect of the humid airflow by setting the water outlet device 22 in the condenser chamber 210 of the condenser 2 and using the water outlet device 22 to cool and condense the humid air in the condenser chamber 210. Therefore, there is no need to set up a further turbulence structure in the condenser chamber 210, which reduces the flow rate attenuation of the airflow in the condenser 2. The airflow velocity in the condenser 2 is fast, which improves the drying performance of the clothing processing equipment 1.
[0053] Furthermore, the airflow of the garment processing equipment 1 is generally provided by a fan. Since the inner wall of the condensation chamber 210 of the condenser 2 of this application does not have structures such as water-blocking ribs or flow channels, the airflow speed is fast, which reduces the attenuation effect on the airflow flowing through the condensation chamber 210, further improving the drying performance of the garment processing equipment 1 and reducing the energy consumption during drying.
[0054] According to one embodiment of the present invention, the water outlet device 22 is provided with a water outlet hole 221. There are multiple water outlet holes 221 arranged at intervals on the outer periphery of the water outlet device 22. The multiple water outlet holes 221 are arranged at intervals, so that the spraying of cooling water is more uniform and the cooling water is dispersed in the condensation chamber 210, thereby fully exchanging heat with the high temperature and humid airflow flowing through the condensation chamber 210 and improving the condensation effect of the condenser 2.
[0055] According to one embodiment of the present invention, the condenser housing 21 is provided with a condensation inlet 2101 and a condensation outlet 2102 communicating with the condensation chamber 210. The condensation inlet 2101 is located below the condensation outlet 2102. The high-temperature and humid airflow will flow from bottom to top. By placing the condensation inlet 2101 below the condensation outlet 2102, it can better conform to the flow law of the high-temperature and humid airflow, and the high-temperature airflow will flow more smoothly through the condensation chamber 210.
[0056] According to one embodiment of the present invention, the condenser inlet 2101 is located on the upper side of the barrel assembly 11. Typically, the condenser outlet 2102 is located on the upper part of the barrel assembly. Setting the condenser inlet 2101 on the upper side of the barrel assembly 11 can reduce the distance between the condenser inlet 2101 and the condenser outlet 2102, thereby reducing the volume of the condenser 2, making the arrangement of the condenser 2 simpler and more convenient, reducing the manufacturing cost of the condenser 2, and at the same time further improving the airflow speed and improving the drying efficiency.
[0057] According to one embodiment of the present invention, the water outlet device 22 extends obliquely from the condenser inlet 2101 to the condenser outlet 2102. The oblique extension of the water outlet device 22 firstly increases the length of the water outlet device 22, and more water outlet holes 221 can be arranged on the water outlet device 22, thereby increasing the output of cooling water and enhancing the condenser 2's condensation effect on high-temperature and humid air.
[0058] Furthermore, the water outlet device 22 itself can come into contact with the airflow, thereby using its own structure to exchange heat with the airflow in the condensation chamber 210. The water outlet device 22 is tilted in the direction from the condensation inlet 2101 to the condensation outlet 2102, which increases the contact area and contact time between the water outlet device 22 and the high-temperature and humid airflow, further enhancing the heat exchange capacity of the water outlet device 22 for the airflow in the condensation chamber 210.
[0059] Specifically, the water outlet device 22 can be inclinedly installed on the side wall of the condensing chamber 210. This inclination effectively increases the contact area between the water outlet device 22 and the airflow within the condensing chamber 210, thereby improving the condensation efficiency of the condenser 2. Furthermore, the condensing chamber 210 can be formed by multiple walls. The water outlet device 22 can be installed on the widest wall and extend inclinedly thereafter to further increase the contact area between the water outlet device 22 and the airflow within the condensing chamber 210, prolonging the contact time between the airflow and the water outlet device 22, increasing the spray range of the water outlet device 22, and further enhancing the condenser's dehumidification effect on high-temperature, humid airflow.
[0060] like Figure 5As shown, according to an embodiment of the present invention, a plurality of water outlet holes 221 are provided on the outer periphery of the water outlet device 22. The plurality of water outlet holes 221 are arranged at intervals in the extending direction of the water outlet device 22. The water outlet holes 221 are adapted to spray the cooling water in the water outlet device 22 into the condensation chamber 210 so that the cooling water in the condensation chamber 210 can fully contact the high temperature and humid air.
[0061] The water outlet holes 221 are positioned on the outer periphery of the water outlet device 22, allowing the water outlet device 22 to spray water towards various locations within the condensation chamber 210, thereby uniformly reducing the temperature within the condensation chamber 210 and improving the dehumidification efficiency of the condenser 2. Arranging the water outlet holes 221 at intervals along the extension direction of the water outlet device 22 further expands the coverage area of the cooling water sprayed by the water outlet device 22, ensuring that the cooling water can be sprayed onto every corner of the condensation chamber 210, resulting in more thorough dispersion of the cooling water.
[0062] like Figure 7 As shown, according to one embodiment of the present invention, a condensation channel 24 is formed on the inner wall of the condensation chamber 210. The upstream end of the condensation channel 24 is adjacent to the water outlet device 22, and the downstream end of the condensation channel 24 is adjacent to the condensation outlet 2102. The condensation channel 24 can be constructed as a groove formed in the inner wall of the condensation chamber 210. After the high-temperature and humid gas comes into contact with the inner wall of the condensation chamber 210, condensate is formed on the inner wall of the condensation chamber 210. The condensate is dispersed on the inner wall of the condensation chamber 210. By setting the condensation channel 24, the condensate can be collected along the direction of the condensation channel 24 and flow along the extension direction of the condensation channel 24. The condensate condensed on the inner wall of the condensation chamber 210 flows along the extension direction of the condensation channel 24. Under the guidance of the condensation channel 24, the condensate flows into the tank assembly 11 through the condensation inlet 2101.
[0063] Furthermore, after being sprayed, part of the cooling water flows directly out of the condensing chamber 210 through the condenser outlet 2102, while the other part of the cooling water is sprayed onto the inner wall of the condensing chamber 210 and collects in the condensing water channel 24. During the flow of the condensing water channel 24, the cooling water continues to contact the airflow for heat exchange, so as to make full use of the cooling capacity of the cooling water and reduce the temperature of the airflow in the condensing chamber 210. The setting of the condensing water channel 24 extends the flow path of the cooling water, improves the condensation effect of the condenser 2, and also reduces the amount of cooling water used.
[0064] like Figure 7As shown, according to one embodiment of the present invention, the condensate channel 24 includes a plurality of sequentially connected connecting segments 241, with adjacent connecting segments 241 extending in different directions. The condensate channel 24 is constructed as a waterway structure with multiple straight bends. Constructing the condensate channel 24 as a waterway structure with multiple bends increases the coverage area of the condensate channel 24 on the inner wall of the condensation chamber 210, so that the condensate in the inner wall of the condensation chamber 210 flows mainly through the condensate channel 24 and does not naturally collect and drip, reducing the noise in the washing machine. When the cooling water collects in the condensate channel 24, it can prolong the flow time of the cooling water in the condensation chamber 210, so that the cooling water can fully exchange heat in the condensation chamber 210, improve the heat exchange efficiency of the cooling water, and reduce the amount of cooling water used.
[0065] According to one embodiment of the present invention, the upstream connecting section 241 is arranged parallel to the water outlet device 22. The temperature around the water outlet device 22 is the lowest, the condensation effect is good, and the condensate is easier to condense. At the same time, the cooling water can be sprayed directly into the condensate channel 24 after being sprayed out. The condensate channel 24 is constructed as a broken line segment. After the upstream connecting section 241 of the condensate channel 24 is arranged parallel to the water outlet device 22, the cooling water and condensate are more easily collected in the connecting section 241.
[0066] The following is a brief description of the garment processing device 1 according to the present invention.
[0067] like Figure 1-3 As shown, the garment processing device 1 according to the present invention includes: a drum assembly 11 and a condenser 2, wherein a drying chamber 1121 is formed within the drum assembly 11; the condenser 2 is constructed as described in any of the above embodiments, and the condensation chamber 210 within the condenser 2 is connected to the drying chamber 1121. Because the garment processing device 1 according to the present invention is equipped with the condenser 2 of the above embodiments, lint is less likely to accumulate in the condensation chamber 210 of the garment processing device 1, airflow is smooth, and drying efficiency is high.
[0068] The drum assembly 11 is provided with a drying chamber 1121, which is used to hold clothes to be dried. The clothes are placed in the drying chamber 1121 so that the clothes can be dried by the condenser 2 and other components in the clothes processing equipment 1.
[0069] The condenser 2 is disposed on the drum assembly 11 and has a condensation chamber 210 formed inside it. The condensation chamber 210 is suitable for airflow. In some embodiments, the airflow can circulate between the drying chamber 1121 and the condensation chamber 210 of the drum assembly 11 to dry the clothes in the drying chamber 1121. During the airflow circulation, the moisture of the clothes in the drying chamber 1121 is carried away. When the hot and humid airflow flows through the condensation chamber 210 in the condenser 2, the water in the airflow is condensed in the condensation chamber 210 and separated into dry airflow, so as to dry the clothes when it circulates through the drying chamber 1121 and take away the moisture of the clothes.
[0070] A water outlet device 22 is installed inside the condenser 210. The water outlet device 22 is located inside the condensation chamber 210 and is adapted to spray cooling water into the condensation chamber 210 to exchange heat with the airflow flowing through the condensation chamber 210, thereby reducing the temperature inside the condensation chamber 210 and causing the humid and hot airflow to precipitate the water it carries after flowing through the condensation chamber 210. By placing the water outlet device 22 inside the condensation chamber 210 and using the water outlet device 22 to spray cooling water into the condensation chamber 210, the condensation effect is good, and the water outlet device 22 has little obstruction to the airflow.
[0071] According to one embodiment of the present invention, both the condenser inlet 2101 and the condenser outlet 2102 are located at the upper part of the tank assembly 11. Since the water outlet device 22 is set inside the condenser chamber 210, the condenser 2 has a good condensation effect and does not require a long condensation time. By setting both the condenser inlet 2101 and the condenser outlet 2102 at the upper part of the tank assembly 11, the distance between the condenser inlet 2101 and the condenser outlet 2102 is greatly shortened, thereby reducing the volume of the condenser chamber 210.
[0072] In the prior art, the condenser inlet is located at the bottom of the tank assembly, resulting in a large condenser volume. In this application, both the condenser inlet 2101 and the condenser outlet 2102 are located at the top of the tank assembly 11. Therefore, the condenser 2 in this application is smaller in volume, the condenser chamber 210 is smaller in size, and the overall structure is more compact.
[0073] By placing both the condenser inlet 2101 and the condenser outlet 2102 on the upper part of the drum assembly 11, the length of the condenser chamber 210 is effectively shortened. There are no longer any bends in the condenser chamber 210 that obstruct airflow. Therefore, during the drying process, lint is less likely to accumulate in the condenser chamber 210, the airflow is fast and smooth, and the operation of the garment processing equipment 1 is more stable and reliable.
[0074] According to one embodiment of the present invention, the water outlet device 22 is disposed on the inner wall of the condensation chamber 210, and the extension direction of the water outlet device 22 is the same as the flow direction of the airflow. Disposing the water outlet device 22 on the inner wall of the condensation chamber 210 can reduce the influence of the water outlet device 22 on the airflow, reduce the attenuation effect on the airflow velocity in the condensation chamber 210, and reduce the energy consumption of the clothing processing equipment 1 during the drying process.
[0075] like Figure 3 As shown, according to one embodiment of the present invention, the tub assembly 11 includes an outer tub assembly 111 and an inner tub 112 disposed within the outer tub assembly 111. The inner tub 112 forms a drying chamber 1121. The condenser outlet 2102 of the condenser 2 communicates with the drying chamber 1121, and the condenser inlet 2101 of the condenser 2 communicates with the outer tub assembly 111. An air outlet 1110 is provided on the outer tub assembly 111, which communicates with the condenser inlet 2101. The airflow in the outer tub assembly 111 enters the condenser chamber 210 through the air outlet 1110. After condensation in the condenser chamber 210, the airflow becomes dry airflow. The dry airflow further enters the drying chamber 1121 of the inner tub 112 through the condenser outlet 2102 to dry the clothes.
[0076] like Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, the clothing processing equipment 1 further includes a drying device 12. The drying device 12 is disposed on the outer drum assembly 111 and has a drying tunnel formed inside it. The inlet of the drying tunnel is connected to the condenser outlet 2102, and the outlet of the drying tunnel is connected to the drying chamber 1121. After passing through the condenser chamber 210, the airflow becomes a low-temperature dry airflow and enters the drying tunnel. A heating element is disposed in the drying tunnel, so that the airflow is further transformed into a high-temperature dry airflow for drying the clothes in the drying chamber 1121.
[0077] According to one embodiment of the present invention, the drying device 12 further includes a fan component 13, which is located at the inlet of the drying tunnel. The fan component 13 is provided with a fan wheel. The rotation of the fan wheel can generate a negative pressure at the inlet of the drying tunnel to draw the airflow in the condensation chamber 210 into the drying tunnel, thereby providing power for the flow of airflow.
[0078] like Figure 4 As shown, according to an embodiment of the present invention, a plurality of first mounting feet 2103 are provided on the upper part of the condenser housing 21. The plurality of first mounting feet 2103 are arranged around the outer periphery of the condenser outlet 2102. The first mounting feet 2103 are connected to the housing of the fan component 13 to ensure reliable fit between the condenser 2 and the fan component 13.
[0079] According to one embodiment of the present invention, a plurality of second mounting feet 2104 are provided at the lower part of the condenser housing 21. The plurality of second mounting feet 2104 are arranged around the outer periphery of the condenser inlet 2101. The second mounting feet 2104 are connected to the outer barrel assembly 111. The second mounting feet 2104 can be directly aligned with the fastener mounting holes arranged on the outer periphery of the air outlet 1110 in the outer barrel assembly 111. The second mounting feet 2104 are installed in the fastener mounting holes using fasteners to fix the condenser 2 on the outer barrel assembly 111.
[0080] According to an embodiment of the present invention, a garment processing device 1 includes an outer tub assembly 111 and a condenser 2. The outer tub assembly 111 is provided with an air outlet 1110 located at the upper part of the outer tub assembly 111. A condensation chamber 210 is formed inside the condenser 2. A condensation inlet 2101 and a condensation outlet 2102 communicating with the condensation chamber 210 are provided on the condensation chamber 210.
[0081] In related technologies, the inlet of the condenser's flow channel is located below the barrel assembly, the air outlet on the outer barrel assembly is generally located at the lower part of the outer barrel assembly, the condenser outlet 2102 of the condenser 2 is located at the upper part of the outer barrel assembly 111, the condenser 2 is located between the upper and lower parts of the outer barrel assembly 111, and the condenser 2 has a large volume and complex structure.
[0082] According to the garment processing device 1 of this application, the air outlet 1110 is located on the upper part of the outer tub assembly 111, so that the condenser inlet 2101 connected to the air outlet 1110 is also located on the upper part of the outer tub assembly 111, and the condenser outlet 2102 of the condenser 2 is also located on the upper part of the outer tub assembly 111. Accordingly, the volume of the condenser 2 and the capacity of the condenser chamber 210 are further reduced, so that lint does not easily accumulate in the condenser chamber 210 and is easy to clean.
[0083] According to an embodiment of the present invention, the distance between the condenser inlet 2101 and the condenser outlet 2102 is L, and the radius of the outer barrel assembly 111 is R, where L and R satisfy L≤R. By limiting the distance between the condenser inlet 2101 and the condenser outlet 2102 to the above range, the volume of the condenser cavity 210 in the condenser 2 can be small, and it is not easy for lint to accumulate in the condenser cavity 210. At the same time, the condenser cavity 210 with the above dimensions is easy to clean.
[0084] According to one embodiment of the present invention, the distance between the condenser inlet 2101 and the condenser outlet 2102 is L, and the radius of the outer barrel assembly 111 is R, wherein L and R satisfy: 1 / 4R≤L≤R / 2. Within the above range, the volume of the condenser cavity 210 is further reduced, the airflow is smoother, and the condenser cavity 210 is less prone to accumulating lint, making cleaning more convenient.
[0085] like Figure 3As shown, according to one embodiment of the present invention, the garment processing equipment further includes a drying device 12 and a fan component 13. The drying device 12 has a drying tunnel, and a heating element is provided within the drying tunnel for further heating the condensed airflow. The fan component 13 has an air-gathering chamber connected to the drying tunnel, and a fan wheel is provided within the air-gathering chamber. The fan wheel rotates to provide power for the airflow. The fan component 13 also includes a connecting channel 21b, which connects the air-gathering chamber and the condenser inlet. The connecting channel 21b extends horizontally, which can increase the facing area between the air-gathering chamber and the connecting channel 21b, allowing the fan wheel to more effectively drive the airflow during rotation. The connecting channel 21b communicates with the condenser chamber 210, and the condensed low-temperature dry airflow continues to flow downstream into the drying tunnel through the connecting channel 21b. The connecting channel 21b is located above the condenser chamber 210 and extends horizontally.
[0086] like Figure 5 As shown, according to an embodiment of the present invention, an inlet pipe 23 communicating with the inlet end of the water outlet device 22 is provided on the outer side of the condenser housing 21. The inlet end is located at the lowest side of the water outlet device 22. The water outlet device 22 extends obliquely from the condenser inlet 2101 to the condenser outlet 2102. By setting the inlet end at the water outlet device 22, the flow direction of the cooling water is consistent with the flow direction of the airflow, thereby prolonging the contact time between the cooling water and the airflow, improving the heat exchange efficiency of the cooling water to the air, and thus improving the condensation effect of the condenser 2.
[0087] According to one embodiment of the present invention, an inlet pipe 23 is provided on the outside of the condenser housing 21, which is connected to the inlet end of the water outlet device 22. The inlet pipe 23 is adapted to be connected to an external cooling water source. The inlet pipe 23 can guide the external cooling water source to the water outlet device 22 to achieve heat exchange with the airflow in the cooling chamber.
[0088] The control method according to the present invention applied to the above-described garment processing equipment 1 is briefly described below.
[0089] like Figure 3 and Figure 8 As shown, the control method S101 according to the present invention includes: determining that the clothing processing equipment 1 is in the washing stage or the drum self-cleaning stage, and controlling the inner drum 112 to rotate at a preset speed.
[0090] The above control method is applied to the above-mentioned clothing processing equipment 1. After determining that the clothing processing equipment 1 is in the washing stage or the drum self-cleaning stage, the inner drum 112 is controlled to rotate at a preset speed. Since the air outlet 1110 of the outer drum assembly 111 is located at the upper part of the outer drum assembly 111 in the above-mentioned clothing processing equipment 1, and the condenser 2 is small in size, the washing water can be stirred to the upper part of the outer drum assembly 111 during the rotation of the inner drum 112 at the preset speed. The washing water enters the condensing chamber 210 through the air outlet 1110 at the upper part of the outer drum assembly 111. Under the action of inertia, the washing water impacts the inner wall of the condensing chamber 210 to wash away the lint on the inner wall of the condensing chamber 210. Then, under the action of gravity, the washing water carries lint and other debris back to the outer drum assembly 111 through the condensing outlet 2102.
[0091] According to the control method of the present invention, after determining that the washing stage or the drum self-cleaning stage is in progress, the rotation speed of the inner drum 112 is controlled so as to agitate the washing water by using the inner drum 112, so that the washing water enters the condenser chamber 210 to clean the condenser chamber 210, thereby enabling the clothing processing equipment 1 to have an automatic cleaning function for the condenser 2, which facilitates the cleaning of the condenser 2 of the clothing processing equipment 1 and ensures that the clothing processing equipment 1 always maintains good drying performance.
[0092] According to an embodiment of the present invention, before determining that the clothing processing device 1 is in the washing stage or the drum self-cleaning stage, and controlling the inner drum 112 to rotate at a preset speed, the method further includes: S201: determining that the clothing processing device 1 has started washing or the drum self-cleaning stage, and injecting water into the inner drum 112 of the clothing processing device 1 until a preset water level is reached.
[0093] For the cleaning of condenser 2 and the self-cleaning process of the tub, an appropriate amount of cleaning water needs to be injected into the clothing treatment device 1 so that the cleaning water can be agitated into the condensation chamber 210 during the rotation of the inner tub 112. During the process of injecting water into the inner tub 112, it is necessary to ensure that the water in the inner tub 112 reaches a certain level. The preset water level can be the water level that covers the inner tub 112, so that the inner tub 112 can agitate the cleaning water during rotation and ensure that sufficient cleaning water continuously flushes the inner wall of the condensation chamber 210.
[0094] According to an embodiment of the present invention, controlling the inner tub 112 to rotate at a preset speed includes, S203: during a first preset time period of the washing stage or the tub self-cleaning stage, controlling the inner tub 112 to rotate at a preset speed, wherein the first preset time is less than or equal to the total duration of the washing stage or the tub self-cleaning stage.
[0095] According to one embodiment of the present invention, the preset rotation speed of the inner tub 112 is between 100 rpm and 250 rpm. Setting the preset rotation speed of the inner tub 112 to the above-mentioned range allows the inner tub 112 to fully agitate the cleaning water into the condensing chamber, thereby thoroughly cleaning the condenser 2 and effectively cleaning the lint in the condensing chamber 210 of the condenser 2.
[0096] In a preferred embodiment of the present invention, the optimal cleaning effect can be achieved by setting the preset rotation speed of the inner tub 112 to between 180 rpm and 220 rpm.
[0097] The following describes a control method for condenser self-cleaning according to the present invention applied to the above-described garment processing equipment 1.
[0098] like Figure 3 and Figure 8 As shown, the control method according to the present invention is applied to the aforementioned clothing processing equipment. The method includes: S102, determining that the clothing processing equipment is in the washing stage or the drum self-cleaning stage, and controlling the inner drum to rotate at a preset speed.
[0099] The aforementioned condenser self-cleaning control method is applied to the aforementioned clothing processing equipment 1. When the clothing processing equipment 1 is in the washing stage or the drum self-cleaning stage, when a certain level of water accumulates between the inner and outer drums, the inner drum is controlled to rotate at a preset speed. Since the air outlet 1110 of the outer drum assembly 110 is located at the top of the outer drum assembly 110 in the aforementioned clothing processing equipment 1, and the condenser 2 is small in size, during the process of the inner drum rotating at a higher preset speed, the water can be stirred to the top of the outer drum assembly 110 under the action of centrifugal force. The water enters the condensing chamber 210 through the air outlet 1110 at the top of the outer drum assembly 110. Under the action of inertia, the water impacts the inner wall of the condensing chamber 210 to wash away the lint on the inner wall of the condensing chamber 210. Subsequently, under the action of gravity, the water that has washed the inner wall carries lint and other impurities back to the outer drum assembly 110 through the condensing inlet 2101 and is discharged through the drainage channel of the clothing processing equipment 1.
[0100] According to the control method of the present invention, when it is determined that the washing stage or the drum self-cleaning stage is in progress, the rotation speed of the inner drum is increased to agitate the washing water using the centrifugal force of the inner drum, so that the washing water enters the condenser chamber 210 to clean the condenser chamber 210, thereby enabling the garment processing equipment 1 to have a self-cleaning function for the condenser 2 to maintain good drying performance.
[0101] like Figure 9 As shown, according to an embodiment of the present invention, before determining that the garment processing equipment is in the washing stage or the drum self-cleaning stage and controlling the inner drum to rotate at a preset speed, the method further includes: S202, determining that the garment processing equipment has started washing or the drum self-cleaning stage, and injecting water into the garment processing equipment.
[0102] The cleaning process of condenser 2 requires that there be enough water in the outer tub assembly 110 of the garment processing equipment 1. During the washing or self-cleaning process, a certain amount of water is usually kept in the outer tub assembly 110. Therefore, the water in the outer tub assembly 110 can be used to clean condenser 2.
[0103] In some embodiments, the washing stage includes a main washing stage and a rinsing stage. When the garment handling equipment 1 determines that the main washing stage or the rinsing stage is to begin, a certain level of water is injected into the inner tub, which can be the water level above the level of the clothes to be washed or rinsed in the inner tub. At this time, a portion of the water in the inner tub flows into the space between the inner and outer tubs, so that when the inner tub agitates the washing water, there is sufficient water to continuously flush the inner wall of the condensation chamber 210.
[0104] In other embodiments, the bucket self-cleaning phase includes cleaning the inner bucket and / or outer bucket assembly 110, with water used for cleaning flowing between the inner and outer buckets.
[0105] like Figure 10 As shown, according to an embodiment of the present invention, determining that the clothing processing equipment is in the washing or drum self-cleaning stage and controlling the inner drum to rotate at a preset speed includes: S204, determining that the parameters of the clothing processing equipment in the washing or drum self-cleaning process meet the preset conditions, and closing the drain channel;
[0106] In this embodiment, during the washing stage or the initial stage of the drum self-cleaning process, when the parameters of the washing or drum self-cleaning process of the clothing handling equipment do not meet the preset conditions, the water in the outer drum assembly 110 contains a large amount of pollutants and impurities, making it unsuitable for cleaning the condenser 2. At this time, the inner drum is controlled to rotate at a normal speed to perform the washing, rinsing, or drum self-cleaning program, and the water containing a high concentration of pollutants is discharged. When the parameters of the washing or drum self-cleaning process of the clothing handling equipment meet the preset conditions, the content of pollutants and impurities in the water in the outer drum assembly 110 is greatly reduced, making it suitable for cleaning the condenser 2. At this time, the drain channel is closed to ensure that sufficient water remains in the outer drum assembly 110. The parameters include at least one of the following: the number of water inlets or drains, the number of rinses, the turbidity value of the water in the outer drum assembly 110, and the number of water circulation filtrations. The preset conditions can be at least one of the following: the number of water inlets or drains reaches a preset number, the number of rinses reaches a preset number, the turbidity value of the water in the outer drum assembly 110 is less than a preset threshold, and the number of water circulation filtrations in the outer drum assembly 110 reaches a preset number.
[0107] According to an embodiment of the present invention, the method further includes: S206, controlling the inner tub to rotate at a preset speed during a first preset time period of the washing stage or the tub self-cleaning stage, wherein the first preset time is less than or equal to the total duration of the washing stage or the tub self-cleaning stage.
[0108] In this embodiment, when the drain channel is closed to allow the water level in the outer tub assembly 110 to reach a preset level, the rotation speed of the inner tub is increased and maintained for a first preset time. This allows the water in the outer tub assembly 110 to enter the condenser 2 for cleaning under the centrifugal force of the inner tub. This method can reduce energy and water consumption, reduce the time of ineffective self-cleaning of the condenser 2, prevent contaminants and impurities in the water after washing, rinsing, or tub self-cleaning from remaining in the condenser 2, and improve the self-cleaning efficiency of the condenser 2.
[0109] According to one embodiment of the present invention, the preset rotation speed of the inner tub is between 100 rpm and 250 rpm. Setting the preset rotation speed of the inner tub within this range generates sufficient centrifugal force to ensure that the rotation of the inner tub can thoroughly agitate the cleaning water into the condensing chamber 2, thereby thoroughly cleaning the condenser 2 and effectively removing lint from the condensing chamber 210 of the condenser 2. In a preferred embodiment of the present invention, a preset rotation speed of the inner tub between 180 rpm and 220 rpm achieves the optimal cleaning effect.
[0110] According to one embodiment of the present invention, the first preset time is less than or equal to the total duration of the washing phase or the drum self-cleaning phase.
[0111] According to an embodiment of the present invention, the method further includes: S208, determining that the inner tub rotates at a preset speed for a first preset time, stopping the rotation of the inner tub and draining the water.
[0112] In this embodiment, when the inner tub rotates at a preset speed for a first preset time, the water flushing the condenser 2 contains a large amount of impurities and flows back into the outer tub assembly 110 under gravity. At this time, the rotation of the inner tub is stopped and the drainage channel is opened to discharge the impurities from the clothing processing device 1. In some embodiments, the above process can be repeated a preset number of times to clean the impurities in the condenser 2. The preset number of times can be set by those skilled in the art in combination with actual needs.
