Description

Technical Field

[0001] This utility model relates to the technical field of clothing processing equipment, specifically, to a clothing processing device. Background Technology

[0002] With the continuous progress of society and the economy, people have higher requirements for the washing quality and hygiene safety of clothing. Therefore, in recent years, washing and drying different types of clothing separately has become a trend. In related technologies, clothing processing equipment includes a housing and multiple processing drums. The multiple processing drums are located inside the housing to process different types of clothing separately. However, the layout of the processing drums and surrounding components inside the housing is unreasonable, resulting in low space utilization within the housing and a large overall size of the machine. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a garment processing device with compactly arranged components, which helps to improve the space utilization rate inside the machine casing and reduce the overall size of the machine.

[0005] The garment processing device of this utility model includes: a housing; a first processing cylinder and a second processing cylinder, the first processing cylinder and the second processing cylinder being disposed inside the housing, the first processing cylinder being located above the second processing cylinder; and a heat pump system, the heat pump system being disposed inside the housing, the heat pump system including an evaporator and a condenser, the evaporator and the condenser being both located above the second processing cylinder, and the evaporator and the condenser being arranged along the vertical direction of the housing.

[0006] According to the clothing processing device of this utility model, different clothes or other items to be processed can be classified and placed into the first processing cylinder and the second processing cylinder for processing, thereby improving the flexibility of the clothing processing device during use. Since the evaporator and condenser are both located on the upper side of the second processing cylinder, the upper space of the second processing cylinder in the casing can be utilized. Furthermore, the evaporator and condenser are arranged along the vertical direction of the casing. Compared with the scheme of "horizontal arrangement of condenser and evaporator", the condenser and evaporator of this utility model do not additionally increase the size of the casing in the front-back or left-right direction, which is beneficial to improving the structural compactness of the component arrangement inside the casing.

[0007] Therefore, the clothing processing equipment of this utility model has a compact component arrangement, which is conducive to improving the space utilization rate inside the machine casing and reducing the overall size of the machine.

[0008] In some embodiments, both the evaporator and the condenser are located at the rear of the first processing cylinder. By placing both the evaporator and the condenser at the rear of the first processing cylinder, the clothing processing device of this embodiment can utilize the space behind the first processing cylinder, which helps to reduce the size of the casing in both the vertical and horizontal directions.

[0009] Alternatively, both the evaporator and the condenser can be located on one side of the first processing cylinder in the left-right direction. By placing both the evaporator and the condenser on one side of the first processing cylinder in the left-right direction, the clothing processing device of this embodiment can utilize the space on the left or right side of the first processing cylinder, which helps to reduce the size of the casing in the vertical and horizontal directions as well as the front-back direction.

[0010] Alternatively, both the evaporator and the condenser can be located behind the first processing cylinder and spaced apart along the left-right direction of the casing. This avoids the problem of the evaporator and condenser occupying a large amount of internal space due to stacking them together.

[0011] In some embodiments, the evaporator and the condenser are respectively provided on any two of the following: the rear side of the first processing cylinder, one side of the first processing cylinder in the left-right direction, the lower side of the first processing cylinder, and the upper side of the first processing cylinder. By arranging the evaporator and condenser in the above-described positions, the clothing processing device of this embodiment can fully utilize the space around the first processing cylinder and avoid the problem of occupying a large amount of internal space due to the overall stacking of the evaporator and condenser.

[0012] In some embodiments, the first processing drum includes a first left drum and a first right drum, which are arranged at intervals along the left-right direction of the casing. The evaporator includes two first evaporators, and the condenser includes two first condensers. One set of the first evaporators and first condensers is matched with the first left drum, and the other set of the first evaporators and first condensers is matched with the first right drum. Since the first left drum and the first right drum use different evaporators and condensers for independent heat exchange, the drying efficiency of the first left drum and the first right drum can be improved. Furthermore, the problem of cross-contamination of bacteria in different processing drums caused by cross-flow of heat exchange air can be avoided, which is beneficial to improving the cleanliness of clothes after drying.

[0013] In some embodiments, one set of the first evaporator and the first condenser is located at the rear of the first left cylinder, and another set of the first evaporator and the first condenser is located at the rear of the first right cylinder. Thus, the two sets of first evaporators and first condensers can fully utilize the space at the rear of the first left and first right cylinders, which is beneficial for improving the compactness of the component arrangement within the casing.

[0014] In some embodiments, one set of the first evaporator and the first condenser is disposed behind one of the first left cylinder and the first right cylinder, and another set of the first evaporator and the first condenser is disposed between the first left cylinder and the first right cylinder. This allows for the utilization of the space between the first left cylinder and the first right cylinder, resulting in a more compact arrangement of components within the casing and higher space utilization.

[0015] Alternatively, both sets of the first evaporator and the first condenser can be located between the first left cylinder and the first right cylinder. This allows for the utilization of the space between the first left cylinder and the first right cylinder, resulting in a more compact arrangement of components within the casing and higher space utilization.

[0016] In some embodiments, the evaporator further includes a second evaporator, and the condenser further includes a second condenser. The second evaporator and the second condenser are located behind the first processing cylinder and are matched with the second processing cylinder. The first and second processing cylinders can use different evaporators and condensers for independent heat exchange and drying. This can improve the drying efficiency of the first and second processing cylinders and avoid cross-contamination of bacteria in different processing cylinders caused by cross-flow of heat exchange air, thus improving the cleanliness of the clothes after drying. In addition, the second evaporator and the second condenser are located behind the first processing cylinder, which allows for the utilization of the space behind the first processing cylinder, thus improving space utilization.

[0017] In some embodiments, the heat pump system includes a first air duct and a first fan. The evaporator includes a first evaporator, and the condenser includes a first condenser. The first air duct communicates with the first processing cylinder. The first evaporator, the first condenser, and the first fan are all located in the first air duct, and the first condenser is located above the first evaporator. The humid, high-temperature airflow inside the first processing cylinder can be condensed by the first evaporator to remove condensate, and then enter the first condenser for heating to increase the airflow temperature. In other words, the humid, hot air inside the first processing cylinder can be converted into dry, hot air by the first evaporator and the first condenser to dry the clothes inside the first processing cylinder. Because the first condenser is located above the first evaporator, the probability of condensate from the first evaporator entering the first condenser is reduced, which helps to further reduce moisture in the first air duct, improve the heat exchange effect of the first condenser and the first evaporator, and improve the smoothness of airflow.

[0018] In some embodiments, the first air duct includes a first air outlet pipe, a first intermediate pipe, and a first air inlet pipe, which are sequentially connected. Both the first air outlet pipe and the first air inlet pipe extend along the front-rear direction of the housing. The first air outlet pipe is located between the first processing cylinder and the second processing cylinder, and the first air inlet pipe is located above the first processing cylinder. The first intermediate pipe extends along the vertical direction of the housing and is located behind the first processing cylinder. Because the first intermediate pipe extends along the vertical direction of the housing and is located behind the first processing cylinder, it can fully utilize the space behind the first processing cylinder to optimize the arrangement of components within the housing, thereby reducing the overall size of the garment processing equipment.

[0019] In some embodiments, the first evaporator and the first condenser are disposed within the first intermediate tube. This allows the first evaporator and the first condenser to make full use of the space within the first intermediate tube, resulting in a more compact structural arrangement of the first air duct, the first evaporator, and the first condenser, and higher heat exchange efficiency.

[0020] In some embodiments, the heat pump system further includes a second air duct and a second fan. The evaporator includes a second evaporator, and the condenser includes a second condenser. The second air duct communicates with the second processing cylinder. The second evaporator, the second condenser, and the second fan are all located in the second air duct, and the second condenser is located above the second evaporator. The humid, high-temperature airflow inside the second processing cylinder can be condensed in the second evaporator to remove condensate, and then enter the second condenser for heating to increase the airflow temperature. In other words, the humid, hot air inside the second processing cylinder can be converted into dry, hot air by the second evaporator and the second condenser to dry the clothes inside the second processing cylinder. Because the second condenser is located above the second evaporator, the probability of condensate from the second evaporator entering the second condenser is reduced, which helps to further reduce moisture in the second air duct, improve the heat exchange efficiency of the second condenser and the second evaporator, and improve the smoothness of airflow.

[0021] In some embodiments, the second air duct includes a second outlet pipe, a second intermediate pipe, and a second inlet pipe, which are sequentially connected. The second outlet pipe extends along the front-rear direction of the casing, while the second intermediate pipe and the second inlet pipe extend along the vertical direction of the casing and are arranged side by side. The second intermediate pipe and the second inlet pipe are located behind at least one of the first and second processing cylinders. The second evaporator and the second condenser are located in either the second intermediate pipe or the second inlet pipe. The second outlet pipe, the second intermediate pipe, and the second inlet pipe can be arranged in a generally U-shaped configuration, and the second intermediate pipe and the second inlet pipe are located behind at least one of the first and second processing cylinders. This arrangement allows for a more compact overall structure of the second air duct and enables the second intermediate pipe and the second inlet pipe to fully utilize the space behind the second processing cylinder and / or the second processing cylinder. This optimizes the arrangement of components within the casing and helps reduce the overall size of the machine. Attached Figure Description

[0047] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0048] The following is a reference appendix. Figures 1 to 8 This invention describes a garment processing device according to an embodiment of the present invention.

[0049] like Figures 1 to 4 and Figure 8As shown, the garment processing device of this utility model embodiment includes: a housing 3, a first processing cylinder 1, a second processing cylinder 2, and a heat pump system 4. The first processing cylinder 1 and the second processing cylinder 2 are disposed inside the housing 3, with the first processing cylinder 1 located above the second processing cylinder 2. The heat pump system 4 is disposed inside the housing 3 and includes an evaporator 41 and a condenser 42. Both the evaporator 41 and the condenser 42 are located above the second processing cylinder 2 and are arranged along the vertical direction of the housing 3.

[0050] According to the clothing processing device of the present invention, different clothes or other items to be processed can be classified and placed into the first processing cylinder 1 and the second processing cylinder 2 for processing, thereby improving the flexibility of the clothing processing device during use. Since the evaporator 41 and the condenser 42 are both located on the upper side of the second processing cylinder 2, the upper space of the second processing cylinder 2 in the housing 3 can be utilized. Furthermore, the evaporator 41 and the condenser 42 are arranged along the vertical direction of the housing 3. Compared with the scheme of "the condenser 42 and the evaporator 41 are arranged horizontally", the condenser 42 and the evaporator 41 of the present invention do not additionally increase the size of the housing 3 in the front-back or left-right direction, which is beneficial to improving the structural compactness of the component arrangement inside the housing 3.

[0051] Therefore, the clothing processing equipment of this utility model has a compact component arrangement, which is conducive to improving the space utilization rate inside the casing 3 and reducing the overall size of the machine.

[0052] Optionally, such as Figure 3 As shown, both the evaporator 41 and the condenser 42 are located behind the first processing cylinder 1. It can be understood that "both the evaporator 41 and the condenser 42 are located behind the first processing cylinder 1" includes at least the following situations: the evaporator 41 and the condenser 42 are located directly behind the first processing cylinder 1, slightly above the rear of the first processing cylinder 1, slightly below the rear of the first processing cylinder 1, slightly to the left of the rear of the first processing cylinder 1, or slightly to the right of the rear of the first processing cylinder 1.

[0053] The clothing processing device of this utility model can utilize the space behind the first processing cylinder 1 by placing both the evaporator 41 and the condenser 42 on the rear side of the first processing cylinder 1, which is beneficial to reducing the size of the casing 3 in the vertical and horizontal directions.

[0054] like Figure 2As shown, the axial dimension (i.e., the dimension in the front-to-back direction) of the first processing cylinder 1 is smaller than the axial dimension of the second processing cylinder 2, and the extraction port at the front end of the first processing cylinder 1 is roughly flush with the extraction port at the front end of the second processing cylinder 2. Thus, the upper side of the second processing cylinder 2, the rear side of the first processing cylinder 1, and the rear wall of the casing 3 define a first receiving area 31. The condenser 42 and the evaporator 41 are vertically arranged in the first receiving area 31 to utilize the rear space of the first processing cylinder 1.

[0055] Optionally, such as Figure 4 As shown, both the evaporator 41 and the condenser 42 are located on one side of the first processing cylinder 1 in the left-right direction. It can be understood that the evaporator 41 and the condenser 42 are arranged along the left-right direction of the casing 3 with respect to the first processing cylinder 1. For example, both the evaporator 41 and the condenser 42 are located on the left side of the first processing cylinder 1. Or, for another example, both the evaporator 41 and the condenser 42 are located on the right side of the first processing cylinder 1.

[0056] like Figure 4 As shown, taking an example where both evaporator 41 and condenser 42 are located on the left side of the first processing cylinder 1. Evaporator 41 and condenser 42 can be located slightly forward of the left side of the first processing cylinder 1, or slightly backward of the left side of the first processing cylinder 1.

[0057] The clothing processing device of this utility model can utilize the space on the left or right side of the first processing cylinder 1 by placing both the evaporator 41 and the condenser 42 on one side in the left-right direction of the first processing cylinder 1, which is beneficial to reducing the size of the casing 3 in the vertical and front-back directions.

[0058] In one example, both the evaporator 41 and the condenser 42 are located behind the first processing cylinder 1 and are spaced apart along the left-right direction of the casing 3. It is understood that one of the evaporator 41 and the condenser 42 is located slightly to the left of the rear of the first processing cylinder 1, and the other is located slightly to the right of the rear of the first processing cylinder 1. This allows the evaporator 41 and the condenser 42 to be spaced apart along the left-right direction of the casing 3, thus avoiding the problem of the evaporator 41 and the condenser 42 occupying a large amount of space inside the casing 3 due to their overall stacking.

[0059] Optionally, an evaporator 41 and a condenser 42 may be respectively provided on any two of the following: the rear side of the first processing cylinder 1, one side of the first processing cylinder 1 in the left-right direction, the lower side of the first processing cylinder 1, and the upper side of the first processing cylinder 1. It is understood that the evaporator 41 may be selected at one of the following locations: the rear side of the first processing cylinder 1, one side of the first processing cylinder 1 in the left-right direction, the lower side of the first processing cylinder 1, and the upper side of the first processing cylinder 1; and the condenser 42 may be selected at another of the following locations: the rear side of the first processing cylinder 1, one side of the first processing cylinder 1 in the left-right direction, the lower side of the first processing cylinder 1, and the upper side of the first processing cylinder 1.

[0060] The clothing processing device of this utility model can make full use of the space around the first processing cylinder 1 by arranging the evaporator 41 and condenser 42 in the above-mentioned positions, and can avoid the problem of occupying a large amount of space inside the casing 3 due to the overall stacking of the evaporator 41 and condenser 42.

[0061] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the first processing cylinder 1 includes a first left cylinder 11 and a first right cylinder 12. The first left cylinder 11 and the first right cylinder 12 are arranged at intervals along the left and right directions of the casing 3. The evaporator 41 includes two first evaporators 411, and the condenser 42 includes two first condensers 421. One set of first evaporators 411 and first condensers 421 is matched with the first left cylinder 11, and the other set of first evaporators 411 and first condensers 421 is matched with the first right cylinder 12.

[0062] Understandably, one set of first evaporators 411 and first condensers 421 can exchange heat with the first left cylinder 11 through the air duct 43 to dry the clothes inside the first left cylinder 11. Another set of first evaporators 411 and first condensers 421 can exchange heat with the first right cylinder 12 through the air duct 43 to dry the clothes inside the first right cylinder 12.

[0063] Since the first left drum 11 and the first right drum 12 use different evaporators 41 and condensers 42 for independent heat exchange and drying, on the one hand, the drying efficiency of the first left drum 11 and the first right drum 12 can be improved, and on the other hand, the problem of cross-infection of bacteria in different processing drums caused by the cross of heat exchange airflow can be avoided, which is conducive to improving the cleanliness of clothes after drying.

[0064] Optionally, such as Figure 5 As shown, one set of first evaporators 411 and first condensers 421 is located on the rear side of the first left cylinder 11, and another set of first evaporators 411 and first condensers 421 is located on the rear side of the first right cylinder 12. Thus, the two sets of first evaporators 411 and first condensers 421 can make full use of the space on the rear side of the first left cylinder 11 and the first right cylinder 12, which is beneficial to improving the compactness of the component arrangement inside the casing 3.

[0065] For example, one set of first evaporators 411 and first condensers 421 is located on the same side (left side) of the casing 3 as the first left cylinder 11, and another set of first evaporators 411 and first condensers 421 is located on the same side (right side) of the casing 3 as the first right cylinder 12. This can shorten the extension path of the air duct 43 (first air duct 431) and reduce the space occupied by the air duct 43 in the casing 3.

[0066] Optionally, such as Figure 6As shown, a set of first evaporators 411 and first condensers 421 is located on the rear side of one of the first left cylinder 11 and the first right cylinder 12, and another set of first evaporators 411 and first condensers 421 is located between the first left cylinder 11 and the first right cylinder 12. This allows the space between the first left cylinder 11 and the first right cylinder 12 to be utilized, making the arrangement of components inside the casing 3 more compact and achieving higher space utilization.

[0067] In other examples, both sets of first evaporators 411 and first condensers 421 are located between the first left cylinder 11 and the first right cylinder 12. This allows for the utilization of the space between the first left cylinder 11 and the first right cylinder 12, resulting in a more compact arrangement of components within the casing 3 and higher space utilization.

[0068] In some embodiments, such as Figure 5 and Figure 7 As shown, the evaporator 41 further includes a second evaporator 412, and the condenser 42 further includes a second condenser 422. The second evaporator 412 and the second condenser 422 are located behind the first processing cylinder 1 and are matched with the second processing cylinder 2. It is understood that the first evaporator 411 and the first condenser 421 can exchange heat with the first processing cylinder 1 through the air duct 43 (first air duct 431) to dry the clothes inside the first processing cylinder 1. The second evaporator 412 and the second condenser 422 can exchange heat with the second processing cylinder 2 through the air duct 43 (second air duct 432) to dry the clothes inside the second processing cylinder 2.

[0069] Since the first processing cylinder 1 and the second processing cylinder 2 use different evaporators 41 and condensers 42 for independent heat exchange and drying, on the one hand, the drying efficiency of the first processing cylinder 1 and the second processing cylinder 2 can be improved, and on the other hand, the problem of cross-infection of bacteria in different processing cylinders caused by the cross of heat exchange airflow can be avoided, which is conducive to improving the cleanliness of clothes after drying.

[0070] Optionally, such as Figure 2 As shown, the heat pump system 4 includes a first air duct 431 and a first fan 441. The evaporator 41 includes a first evaporator 411, and the condenser 42 includes a first condenser 421. The first air duct 431 is connected to the first processing cylinder 1. The first evaporator 411, the first condenser 421, and the first fan 441 are all located in the first air duct 431. The first condenser 421 is located above the first evaporator 411 and downstream of the first evaporator 411. It can be understood that the humid, high-temperature airflow in the first processing cylinder 1 can be condensed by the first evaporator 411 to remove condensate from the airflow, and then it can enter the first condenser 421 for heating to increase the temperature of the airflow. That is, the humid, hot air in the first processing cylinder 1 can be converted into dry, hot air by the first evaporator 411 and the first condenser 421 to dry the clothes in the first processing cylinder 1.

[0071] Since the first condenser 421 is located above the first evaporator 411, the probability of condensate in the first evaporator 411 entering the first condenser 421 can be reduced, which is beneficial to further reduce the moisture in the first air duct 431, improve the heat exchange effect of the first condenser 421 and the first evaporator 411, and improve the smoothness of airflow.

[0072] In some embodiments, such as Figure 2 As shown, the first air duct 431 includes a first air outlet pipe 4311, a first intermediate pipe 4312, and a first air inlet pipe 4313. The first air outlet pipe 4311, the first intermediate pipe 4312, and the first air inlet pipe 4313 are connected in sequence. The first air outlet pipe 4311 and the first air inlet pipe 4313 both extend along the front-rear direction of the housing 3. The first air outlet pipe 4311 is located between the first processing cylinder 1 and the second processing cylinder 2. The first air inlet pipe 4313 is located on the upper side of the first processing cylinder 1. The first intermediate pipe 4312 extends along the vertical direction of the housing 3 and is located on the rear side of the first processing cylinder 1.

[0073] It is understandable that the first air outlet pipe 4311 is located upstream of the first intermediate pipe 4312, and the first intermediate pipe 4312 is located upstream of the first air inlet pipe 4313. That is, the air in the first processing cylinder 1 can flow back into the first processing cylinder 1 after passing through the first air outlet pipe 4311, the first intermediate pipe 4312 and the first air inlet pipe 4313.

[0074] Since the first intermediate tube 4312 extends along the vertical direction of the housing 3 and is located on the rear side of the first processing cylinder 1, the first intermediate tube 4312 can make full use of the space on the rear side of the first processing cylinder 1 to optimize the arrangement of the components inside the housing 3 and reduce the overall size of the clothing processing equipment.

[0075] Optionally, such as Figure 2 As shown, the first evaporator 411 and the first condenser 421 are disposed on the first intermediate tube 4312, with the first condenser 421 located above the first evaporator 411. Exemplarily, both the first evaporator 411 and the first condenser 421 are located inside the first intermediate tube 4312. Since the first evaporator 411 and the first condenser 421 are disposed on the first intermediate tube 4312, which extends vertically, the space within the first intermediate tube 4312 can be fully utilized, resulting in a more compact arrangement of the first air duct 431, the first evaporator 411, and the first condenser 421, and higher heat exchange efficiency.

[0076] like Figure 2As shown, the first processing cylinder 1 and the second processing cylinder 2 are arranged in the vertical direction with a certain size interval to form the second receiving area 32. The first air outlet pipe 4311 is arranged in the second receiving area 32. This allows the space between the first processing cylinder 1 and the second processing cylinder 2 to be utilized, thereby making the arrangement of the components inside the housing 3 more compact and helping to reduce the overall size of the machine.

[0077] The first air outlet duct 4311 includes a first vertical air outlet duct 43111 and a first horizontal air outlet duct 43112 connected together. The first vertical air outlet duct 43111 is connected to the front end of the first processing cylinder 1 and extends along the vertical direction of the housing 3. The first horizontal air outlet duct 43112 extends along the front-rear direction of the housing 3 and is located between the first processing cylinder 1 and the second processing cylinder 2. This design facilitates the assembly of the first air outlet duct 4311 with the first processing cylinder 1, and the interface structure between the first air outlet duct 4311 and the first processing cylinder 1 does not occupy the space between the first processing cylinder 1 and the second processing cylinder 2, thus improving the overall compactness of the machine.

[0078] Optionally, such as Figure 7 As shown, the heat pump system 4 also includes a second air duct 432 and a second fan 442. The evaporator 41 includes a second evaporator 412, and the condenser 42 includes a second condenser 422. The second air duct 432 is connected to the second processing cylinder 2. The second evaporator 412, the second condenser 422 and the second fan 442 are all located in the second air duct 432. The second condenser 422 is located above the second evaporator 412.

[0079] Understandably, the humid, high-temperature airflow inside the second processing cylinder 2 can be condensed by the second evaporator 412 to remove the condensate in the airflow, and then it can enter the second condenser 422 for heating to increase the temperature of the airflow. That is, the humid, hot air inside the second processing cylinder 2 can be converted into dry, hot air by the second evaporator 412 and the second condenser 422 to dry the clothes inside the second processing cylinder 2.

[0080] Since the second condenser 422 is located above the second evaporator 412, the probability of condensate in the second evaporator 412 entering the second condenser 422 can be reduced, which is beneficial to further reduce the moisture in the second air duct 432, improve the heat exchange effect of the second condenser 422 and the second evaporator 412, and improve the smoothness of airflow.

[0081] Optionally, such as Figure 7As shown, the second air duct 432 includes a second air outlet pipe 4321, a second intermediate pipe 4322, and a second air inlet pipe 4323. The second air outlet pipe 4321, the second intermediate pipe 4322, and the second air inlet pipe 4323 are connected in sequence. The second air outlet pipe 4321 extends along the front-rear direction of the casing 3. The second intermediate pipe 4322 and the second air inlet pipe 4323 both extend along the vertical direction of the casing 3 and are arranged side by side. The second intermediate pipe 4322 and the second air inlet pipe 4323 are located behind at least one of the first processing cylinder 1 and the second processing cylinder 2. The second evaporator 412 and the second condenser 422 are located in either the second intermediate pipe 4322 or the second air inlet pipe 4323.

[0082] It is understandable that the airflow within the second air duct 432 can flow sequentially along the second outlet pipe 4321, the second intermediate pipe 4322, and the second inlet pipe 4323. The second outlet pipe 4321, the second intermediate pipe 4322, and the second inlet pipe 4323 are generally arranged in a "U" shape, and the second intermediate pipe 4322 and the second inlet pipe 4323 are located behind at least one of the first processing cylinder 1 and the second processing cylinder 2. On the one hand, this makes the overall structure of the second air duct 432 more compact; on the other hand, it allows the second intermediate pipe 4322 and the second inlet pipe 4323 to make full use of the space behind the second processing cylinder 2 and / or the space behind the second processing cylinder 2. This allows for optimization of the arrangement of the components in the housing 3, which is beneficial for reducing the overall size of the machine.

[0083] Optionally, such as Figure 7 As shown, the second evaporator 412 and the second condenser 422 are disposed in either the second intermediate pipe 4322 or the second air inlet pipe 4323. For example, the second evaporator 412 and the second condenser 422 are disposed in the second intermediate pipe 4322. Another example is that the second evaporator 412 and the second condenser 422 are disposed in the second air inlet pipe 4323. Yet another example is that the second evaporator 412 is disposed in the second intermediate pipe 4322, and the second condenser 422 is disposed in the second air inlet pipe 4323.

[0084] The clothing processing device of this utility model, by placing the second evaporator 412 and the second condenser 422 in either the second intermediate pipe 4322 or the second air inlet pipe 4323, can reduce the overall height dimension of the machine compared to the solution of placing the second evaporator 412 and the second condenser 422 in the second air outlet pipe 4321. Furthermore, the space within the second intermediate pipe 4322 and the second air inlet pipe 4323 can be utilized, which is beneficial to improving the compactness of the component arrangement within the casing 3.

[0085] For example, the second evaporator 412 and the second condenser 422 are both disposed inside the second intermediate tube 4322, and the second condenser 422 is disposed above the second evaporator 412.

[0086] Optionally, such as Figure 7 As shown, the second air outlet duct 4321 is arranged in the second receiving area 32. The first processing cylinder 1 and the second processing cylinder 2 are arranged in the vertical direction with a certain size interval to form the second receiving area 32. The second air outlet duct 4321 is arranged in the second receiving area 32, thereby making use of the space between the first processing cylinder 1 and the second processing cylinder 2, which makes the arrangement of components in the housing 3 more compact and helps to reduce the overall size of the machine.

[0087] like Figure 8 As shown, the heat pump system 4 also includes a compressor 45. The first evaporator 411, the second evaporator 412, the first condenser 421, and the second condenser 422 are all connected to the compressor 45 via refrigerant lines. It can be understood that there are three sets of refrigerant lines: two sets are connected to the two sets of first evaporators 411 and first condensers 421 respectively, and the other set is connected to the second evaporator 412 and second condenser 422. It can be understood that the three evaporators 41 and the three condensers 42 share one compressor 45. This reduces the number of components used, lowers the production cost of the clothing processing equipment, and saves space within the casing 3, thereby improving the compactness of the component arrangement within the casing 3.

[0088] It should be noted that the refrigerant pipeline connected to the compressor 45 is equipped with components such as an electronic expansion valve 46, a reversing valve, and a capillary tube, which will not be described in detail in this utility model.

[0089] For example, the compressor 45 is located on the upper side of the second processing cylinder 2, so that the compressor 45 can make full use of the space above the second processing cylinder 2 and is close to the evaporator 41 and condenser 42, so as to facilitate the arrangement of refrigerant pipelines.

[0090] For example, the compressor 45 can be located behind the first processing cylinder 1, and at a position slightly to the left or right of the first processing cylinder 1, so as to facilitate the arrangement of the evaporator 41, the condenser 42 and the surrounding pipelines.

[0091] like Figure 1 As shown, the first left cylinder 11 and the second right cylinder are located on the left and right sides of the second processing cylinder 2, respectively, and the first left cylinder 11 and the first right cylinder 12 are arranged symmetrically from left to right. For example, the first left cylinder 11 and the first right cylinder 12 are symmetrical about a vertical plane passing through the axis of the second processing cylinder 2, or, for example, the first left cylinder 11 and the first right cylinder 12 are symmetrical about a vertical plane passing through the center of the housing 3.

[0092] Thus, the first left cylinder 11 and the first right cylinder 12 are roughly at the same horizontal height, and the distances of the first left cylinder 11 and the first right cylinder 12 from the axis of the second processing cylinder 2 in the left-right direction are roughly equal. On the one hand, this makes the structure of the three processing cylinders more regular, and on the other hand, it makes the center of gravity of the three processing cylinders roughly located in the middle of the casing 3, which is beneficial to improving the stability of the clothing processing equipment during operation.

[0093] like Figure 1 As shown, the first left tube 11 and the first right tube 12 are the same size and shape. Therefore, during the assembly process of the garment processing equipment, the first left tube 11 and the first right tube 12 do not need to prepare their own materials, that is, the materials of the first left tube 11 and the first right tube 12 are interchangeable, thereby reducing production costs and facilitating subsequent maintenance and replacement.

[0094] In other examples, the size and shape of the first left cylinder 11 and the first right cylinder 12 may also be different, and this utility model does not limit this.

[0095] like Figure 1 and Figure 2 As shown, the axes of the first left cylinder 11, the first right cylinder 12, and the second processing cylinder 2 are all parallel to each other, and the retrieval ports of the first left cylinder 11, the first right cylinder 12, and the second processing cylinder 2 are all arranged facing forward, which facilitates daily use by users.

[0096] like Figure 1 As shown, the capacity of either the first left cylinder 11 or the first right cylinder 12 is smaller than that of the second processing cylinder 2, which helps to lower the center of gravity of the clothing processing equipment, making the clothing processing equipment more stable during operation and reducing the overall size of the clothing processing equipment.
