Description

TECHNICAL FIELD

[0001] The utility model relates to clothes processing equipment technical field, specifically, a clothes processing equipment. BACKGROUND

[0002] With the increasingly progress of social economy, people have higher requirements on the washing quality and health safety of clothes. Therefore, in recent years, separate washing and drying of different types of clothes has become a trend. In the related art, the clothes processing equipment includes a cabinet and multiple processing drums, and the multiple processing drums are arranged in the cabinet to process different clothes respectively. However, the arrangement of the processing drums and surrounding components in the cabinet is unreasonable, which leads to low space utilization in the cabinet and large size of the whole machine. SUMMARY

[0003] The utility model aims at solving at least one of the technical problems in the related art to some extent.

[0004] Therefore, the embodiment of the utility model provides a clothes processing equipment, and the components in the clothes processing equipment are arranged compactly, which is beneficial to improve the space utilization in the cabinet and reduce the size of the whole machine.

[0005] The clothes processing equipment of the embodiment of the utility model comprises a cabinet, a first processing drum, a second processing drum and a third processing drum, the first processing drum, the second processing drum and the third processing drum are all arranged in the cabinet, the second processing drum and the third processing drum are both located on the upper side of the first processing drum, and the second processing drum and the third processing drum are arranged at intervals along the left-right direction; a heat pump system is arranged in the cabinet, the heat pump system comprises a first air duct, a first evaporator, a first condenser and a first fan, the first air duct is communicated with the first processing drum, the first evaporator, the first condenser and the first fan are all arranged in the first air duct, the first fan and at least part of the first air duct are located on the upper side of the first processing drum and the rear side of at least one of the second processing drum and the third processing drum.

[0006] According to the clothes processing equipment of the embodiment of the utility model, different clothes or other objects to be processed can be classified and placed into the first processing drum, the second processing drum and the third processing drum for processing, and the three processing drums arranged in the above manner do not occupy a large space in the height direction of the cabinet. Since the first fan and at least part of the first air duct are located on the upper side of the first processing drum and the rear side of at least one of the second processing drum and the third processing drum, the space on the upper side of the first processing drum and the rear side of the second processing drum and / or the third processing drum can be utilized, so that the occupied space of the heat pump system in the cabinet can be reduced, the components in the cabinet are arranged compactly, which is beneficial to improve the space utilization in the cabinet and reduce the size of the whole machine.

[0007] In some embodiments, the first air duct includes a first pipe located above the first processing cylinder and below at least one of the second and third processing cylinders, with both the first evaporator and the first condenser disposed on the first pipe. This allows for the utilization of the space between the second (or third) processing cylinder and the first processing cylinder, resulting in a more compact arrangement of components within the casing and contributing to a reduction in overall machine size.

[0008] In some embodiments, the first air duct includes a second pipe and a third pipe, both extending vertically along the casing and arranged side-by-side. The second pipe and the third pipe are located behind at least one of the second and third processing cylinders. The first evaporator and the first condenser are arranged vertically along the casing and are disposed within either the second or the third pipe. Thus, the arrangement direction of the first evaporator and the first condenser is the same as the extension direction of the second and third pipes, thereby reducing the overall size of the first air duct, the first evaporator, and the first condenser combined. Furthermore, compared to the scheme of "horizontally arranged first evaporator and first condenser," the first evaporator and first condenser of this invention do not additionally increase the dimensions of the casing in the front-back or left-right directions, which is beneficial for improving the structural compactness of the components arranged within the casing.

[0009] In some embodiments, the second pipe is located upstream of the third pipe, and both the first evaporator and the first condenser are located in the second pipe. When the heat exchange airflow flows through the first air duct, the heat exchange airflow in the second pipe flows towards the third pipe. Since both the first evaporator and the first condenser are located in the second pipe, the arrangement of the first evaporator and the first condenser can be optimized, making the overall layout of the heat pump system compact. Furthermore, the first evaporator and the first condenser arranged as described above have a better dehumidification and heating effect on the airflow, which is beneficial to improving drying efficiency.

[0010] In some embodiments, the second pipe is located upstream of the third pipe, and the first fan is located at the connection between the second pipe and the third pipe, or the first fan is located in the third pipe. By arranging the first fan in the above manner, the clothing processing device of this embodiment of the invention helps to increase the flow velocity of the heat exchange airflow entering the first processing drum, thereby improving the efficiency of drying clothes in the first processing drum.

[0011] In some embodiments, the second pipe is located upstream of the third pipe, and the first evaporator, the first condenser, and the first fan are all located within the third pipe. This increases the proportion of the pipe upstream of the third pipe, thereby improving the dehumidification effect of the airflow within the first duct. Furthermore, since the first evaporator, the first condenser, and the first fan are all located within the third pipe, the compactness of their arrangement can be improved, reducing space occupancy.

[0012] In some embodiments, the second pipe is located upstream of the third pipe, the first evaporator is located in the second pipe, and the first condenser is located in the third pipe. The clothing processing device of this embodiment, by arranging the first evaporator and the first condenser in the above-described structure, improves the heat exchange performance of both the first evaporator and the first condenser, further enhancing the dehumidification and heating effect of the airflow.

[0013] In some embodiments, the first fan is disposed in the third pipe. This can increase the flow rate of the air entering the first processing cylinder through the first air duct and reduce airflow obstruction, thereby further improving the drying effect of the first processing cylinder.

[0014] In some embodiments, the heat pump system further includes a second air duct, a second evaporator, and a second condenser. Both the second evaporator and the second condenser are located within the second air duct, which communicates with the second processing cylinder. Along the left-right direction of the housing, the second air duct and the second processing cylinder are located on the same side within the housing. This shortens the extension path of the second air duct and reduces the space it occupies within the housing.

[0015] In some embodiments, the heat pump system further includes a third air duct, a third evaporator, and a third condenser. The third evaporator and the third condenser are both located within the third air duct, which communicates with the third processing cylinder. Along the left-right direction of the housing, the third air duct and the third processing cylinder are located on the same side within the housing. This shortens the extension path of the third air duct and reduces the space it occupies within the housing.

[0016] In some embodiments, the heat pump system further includes a second fan and a third fan, the second fan being disposed in the second air duct and the third fan being disposed in the third air duct. The second fan and the third fan are located above the first processing cylinder and behind at least one of the second and third processing cylinders. The clothing processing device of this embodiment places the second and third fans behind at least one of the second and third processing cylinders, which can fully utilize the rear space of the second and / or third processing cylinders, and helps to reduce the size of the casing in both the vertical and horizontal directions.

[0017] In some embodiments, the first air duct is located between the second and third air ducts. This allows for optimization of the arrangement of the first, second, and third air ducts. On the one hand, it reduces the length of the first, second, and third air ducts, lowering the complexity of the air duct design. On the other hand, since the first air duct is located in the same left-right arrangement as the second and third air ducts, which is consistent with the arrangement of the first, second, and third processing cylinders, the arrangement of the first, second, and third air ducts is more regular, facilitating the arrangement of other components around the heat pump system.

[0041] 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.

[0042] The following is a reference appendix. Figures 1 to 9 This invention describes a garment processing device according to an embodiment of the present invention.

[0043] like Figures 1 to 5 As shown, the clothing processing device of this utility model embodiment includes: a housing 4, a first processing cylinder 1, a second processing cylinder 2, a third processing cylinder 3, and a heat pump system 5. The heat pump system 5 includes a first air duct 531, a first evaporator 511, a first condenser 521, and a first fan 541.

[0044] The first processing cylinder 1, the second processing cylinder 2, and the third processing cylinder 3 are all located inside the casing 4. The second processing cylinder 2 and the third processing cylinder 3 are both located above the first processing cylinder 1. The second processing cylinder 2 and the third processing cylinder 3 are spaced apart in the left-right direction. The heat pump system 5 is located inside the casing 4. The first air duct 531 is connected to the first processing cylinder 1. The first evaporator 511, the first condenser 521, and the first fan 541 are all located in the first air duct 531. The first fan 541 and at least part of the first air duct 531 are located above the first processing cylinder 1 and behind at least one of the second processing cylinder 2 and the third processing cylinder 3.

[0045] 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, the second processing cylinder 2, and the third processing cylinder 3 for processing, and the three processing cylinders arranged as described above will not occupy a large space in the height direction of the housing 4. Since the first fan 541 and at least part of the first air duct 531 are located on the upper side of the first processing cylinder 1 and on the rear side of at least one of the second processing cylinder 2 and the third processing cylinder 3, the upper side of the first processing cylinder 1 and the rear side of the second processing cylinder 2 and / or the third processing cylinder 3 can be utilized, thereby reducing the space occupied by the heat pump system 5 in the housing 4, making the internal components more compact, which is beneficial to improving the space utilization rate in the housing 4 and reducing the overall size of the machine.

[0046] It is understandable that "the first fan 541 and part of the first air duct 531 are located behind at least one of the second treatment cylinder 2 and the third treatment cylinder 3" includes at least the following situations:

[0047] (1) The first fan 541 and part of the first air duct 531 are located at the position directly behind the second processing cylinder 2, at the position slightly above the rear of the second processing cylinder 2, at the position slightly below the rear of the second processing cylinder 2, at the position slightly to the left of the rear of the second processing cylinder 2, or at the position slightly to the right of the rear of the second processing cylinder 2.

[0048] (2) The first fan 541 and part of the first air duct 531 are located at the position directly behind the third processing cylinder 3, at the position slightly above the rear of the third processing cylinder 3, at the position slightly below the rear of the third processing cylinder 3, at the position slightly to the left of the rear of the third processing cylinder 3, or at the position slightly to the right of the rear of the third processing cylinder 3.

[0049] (3) The first fan 541 and part of the first air duct 531 are located at the rear side between the second processing cylinder 2 and the third processing cylinder 3. In this case, in the projection plane orthogonal to the front and rear directions of the casing 4, the projection plane of the first fan 541 and part of the first air duct 531 may or may not overlap with the projection plane of the second processing cylinder 2 and the third processing cylinder 3.

[0050] The garment processing device of this utility model has the first fan 541 and part of the first air duct 531 located on the rear side of at least one of the second processing cylinder 2 and the third processing cylinder 3, which can make full use of the rear space of the second processing cylinder 2 and / or the third processing cylinder 3, and is beneficial to reduce the size of the casing 4 in the vertical and horizontal directions.

[0051] like Figure 2As shown, the axial dimension (i.e., the dimension in the front-to-back direction) of the second processing cylinder 2 (third processing cylinder 3) is smaller than the axial dimension of the first processing cylinder 1, and the retrieval port at the front end of the second processing cylinder 2 (third processing cylinder 3) is roughly flush with the retrieval port at the front end of the first processing cylinder 1. Thus, the upper side of the first processing cylinder 1, the rear side of the second processing cylinder 2 (third processing cylinder 3), and the rear wall of the housing 4 define a first receiving area 41. The first fan 541 and part of the first air duct 531 are arranged in the first receiving area 41 to utilize the rear space of the second processing cylinder 2 and the third processing cylinder 3.

[0052] Optionally, such as Figure 2 As shown, the first air duct 531 includes a first pipe 5311, which is located above the first processing cylinder 1 and below at least one of the second processing cylinder 2 and the third processing cylinder 3. The first evaporator 511 and the first condenser 521 are both located within the first pipe 5311. Figure 2 As shown, the second processing cylinder 2 (third processing cylinder 3) and the first processing cylinder 1 are arranged in the vertical direction with a certain size gap to form a second receiving area 42. The first tube 5311 is arranged in the second receiving area 42. This allows the space between the second processing cylinder 2 (third processing cylinder 3) and the first processing cylinder 1 to be utilized, thereby making the arrangement of the components inside the housing 4 more compact and helping to reduce the overall size of the machine.

[0053] For example, the first evaporator 511 and the first condenser 521 can be arranged horizontally to reduce the height of the arrangement of the first evaporator 511 and the first condenser 521 to adapt to the installation structure of the first processing cylinder 1, the second processing cylinder 2 and the third processing cylinder 3, thereby reducing the overall height of the machine.

[0054] For example, the first evaporator 511 and the first condenser 521 can be arranged horizontally along the front-back direction or the left-right direction of the casing 4.

[0055] Optionally, such as Figure 2 As shown, the first air duct 531 includes a second pipe 5312 and a third pipe 5313. The second pipe 5312 and the third pipe 5313 both extend along the vertical direction of the casing 4 and are arranged side by side. The second pipe 5312 and the third pipe 5313 are located behind at least one of the second processing cylinder 2 and the third processing cylinder 3. The first evaporator 511 and the first condenser 521 are arranged along the vertical direction of the casing 4 and are located in either the second pipe 5312 or the third pipe 5313.

[0056] In the embodiment of the clothing treatment device of the present utility model, the first evaporator 511 and the first condenser 521 are arranged in the up-down direction. Thus, the arrangement direction of the first evaporator 511 and the first condenser 521 is the same as the extension direction of the second pipe 5312 and the third pipe 5313, so that the overall size after the combination of the first air duct 531, the first evaporator 511 and the first condenser 521 can be reduced. And compared with the scheme of "the first evaporator 511 and the first condenser 521 are horizontally arranged", the first evaporator 511 and the first condenser 521 of the present utility model will not additionally increase the size of the casing 4 in the front-back direction or the left-right direction, which is beneficial to improving the structural compactness of the component arrangement in the casing 4.

[0057] Since the space arrangement of the heat pump system 5 in the casing 4 is limited, the first evaporator 511 and the first condenser 521 are arranged in the up-down arrangement manner. According to the up-down arrangement form of the first evaporator 511 and the first condenser 521, the second pipe 5312 and the third pipe 5313 are extended and arranged side by side in the up-down direction of the casing 4, so that the first air duct 531 is generally in a "U" shape. Thus, not only the occupied space of the heat pump system 5 in the casing 4 is reduced, making the component arrangement in the clothing treatment device compact, but also the air flow in the first air duct 531 can be ensured to flow smoothly, which is beneficial to improving the drying effect of the clothes in the first treatment cylinder 1.

[0058] Exemplarily, as Figure 2 shown, the second pipe 5312 and the third pipe 5313 are arranged in the front-back direction of the casing 4. For example, the second pipe 5312 is arranged on the front side of the third pipe 5313, or the second pipe 5312 is arranged on the rear side of the third pipe 5313. By arranging the second pipe 5312 and the third pipe 5313 in the front-back direction of the casing 4, the clothing treatment device of the embodiment of the present utility model can facilitate the arrangement of other components on the left and right sides of the first air duct 531, thus facilitating the arrangement of the components around the first air duct 531 and being beneficial to improving the space utilization rate.

[0059] Exemplarily, the second pipe 5312 and the third pipe 5313 are arranged in the left-right direction of the casing 4. For example, the second pipe 5312 is arranged on the left side of the third pipe 5313, or the second pipe 5312 is arranged on the right side of the third pipe 5313. By arranging the second pipe 5312 and the third pipe 5313 in the left-right direction of the casing 4, it is beneficial to reduce the size of the casing 4 in the front-back direction.

[0060] Optionally, as Figure 2As shown, the second pipe 5312 is located upstream of the third pipe 5313, and both the first evaporator 511 and the first condenser 521 are located on the second pipe 5312. The first condenser 521 is located above the first evaporator 511. It can be understood that when the heat exchange airflow flows through the first air duct 531, the heat exchange airflow in the second pipe 5312 flows towards the third pipe 5313. Since both the first evaporator 511 and the first condenser 521 are located on the second pipe 5312, the arrangement of the first evaporator 511 and the first condenser 521 can be optimized, making the overall layout of the heat pump system 5 compact. Furthermore, the first evaporator 511 and the first condenser 521 arranged as described above have a better dehumidification and heating effect on the airflow, which is beneficial to improving the drying efficiency.

[0061] Optionally, such as Figure 2 As shown, the second pipe 5312 is located upstream of the third pipe 5313, and the first fan 541 is located at the connection point between the second pipe 5312 and the second pipe 5312. Alternatively, as... Figure 3 As shown, the first fan 541 is located in the third pipe 5313. By arranging the first fan 541 in the above manner, the clothing processing device of this embodiment of the present invention can improve the flow rate of the heat exchange airflow entering the first processing cylinder 1, thereby improving the efficiency of drying clothes in the first processing cylinder 1.

[0062] In one example, such as Figure 4 As shown, the second pipe 5312 is located upstream of the third pipe 5313, and the first evaporator 511, the first condenser 521, and the first fan 541 are all located within the third pipe 5313. This increases the proportion of the pipework upstream of the third pipe 5313, thereby improving the dehumidification effect of the airflow within the first air duct 531. Furthermore, since the first evaporator 511, the first condenser 521, and the first fan 541 are all located within the third pipe 5313, the compactness of their arrangement can be improved, reducing space occupancy.

[0063] In one example, such as Figure 5 As shown, the second pipe 5312 is located upstream of the third pipe 5313, the first evaporator 511 is located on the second pipe 5312, and the first condenser 521 is located on the third pipe 5313. The clothing processing device of this embodiment, by arranging the first evaporator 511 and the first condenser 521 in the above-described structure, improves the heat exchange performance of both the first evaporator 511 and the first condenser 521, further enhancing the dehumidification and heating effect of the airflow.

[0064] like Figure 5As shown, the first fan 541 is located in the third pipe 5313 and downstream of the first condenser 521. This can increase the flow rate of the first air duct 531 into the first processing cylinder 1, reduce airflow obstruction, and further improve the drying effect of the first processing cylinder 1.

[0065] Optionally, such as Figure 6 As shown, the heat pump system 5 also includes a second air duct 532, a second evaporator 512 and a second condenser 522. The second evaporator 512 and the second condenser 522 are both located in the second air duct 532. The second air duct 532 is connected to the second processing cylinder 2. Along the left and right direction of the casing 4, the second air duct 532 and the second processing cylinder 2 are located on the same side inside the casing 4.

[0066] It is understandable that the second air duct 532 and the second processing cylinder 2 can be located on the left side of the housing 4 at the same time, or on the right side of the housing 4 at the same time. This can shorten the extension path of the second air duct 532 and reduce the space occupied by the second air duct 532 in the housing 4.

[0067] For example, the second condenser 522 is located above the second evaporator 512, and both the second condenser 522 and the second evaporator 512 are located behind the second processing cylinder 2, thereby making use of the space behind the second processing cylinder 2.

[0068] Optionally, such as Figure 6 As shown, the second air duct 532 includes a second air outlet pipe 5321, a second intermediate pipe 5322, and a second air inlet pipe 5323. The second air outlet pipe 5321, the second intermediate pipe 5322, and the second air inlet pipe 5323 are connected in sequence. Both the second air outlet pipe 5321 and the second air inlet pipe 5323 extend along the front-rear direction of the housing 4. The second air outlet pipe 5321 is located between the second processing cylinder 2 and the first processing cylinder 1. The second air inlet pipe 5323 is located on the upper side of the second processing cylinder 2. The second intermediate pipe 5322 extends along the vertical direction of the housing 4 and is located on the rear side of the second processing cylinder 2.

[0069] It is understandable that the second air outlet pipe 5321 is located upstream of the second intermediate pipe 5322, and the second intermediate pipe 5322 is located upstream of the second air inlet pipe 5323. That is, the air in the second treatment cylinder 2 can flow back into the second treatment cylinder 2 after passing through the second air outlet pipe 5321, the second intermediate pipe 5322, and the second air inlet pipe 5323.

[0070] Since the second intermediate tube 5322 extends along the vertical direction of the housing 4 and is located behind the second processing cylinder 2, the second intermediate tube 5322 can make full use of the space behind the second processing cylinder 2 to optimize the arrangement of the components inside the housing 4 and reduce the overall size of the clothing processing equipment.

[0071] Optionally, such as Figure 6 As shown, the second evaporator 512 and the second condenser 522 are disposed on the second intermediate tube 5322, with the second condenser 522 located above the second evaporator 512. Exemplarily, both the second evaporator 512 and the second condenser 522 are located inside the second intermediate tube 5322. Since the second evaporator 512 and the second condenser 522 are disposed on the second intermediate tube 5322, which extends vertically, the second evaporator 512 and the second condenser 522 can fully utilize the space within the second intermediate tube 5322, resulting in a more compact structural arrangement of the second air duct 532, the second evaporator 512, and the second condenser 522, and higher heat exchange efficiency.

[0072] Optionally, such as Figure 7 As shown, the heat pump system 5 also includes a third air duct 533, a third evaporator 513, and a third condenser 523. The third evaporator 513 and the third condenser 523 are both located within the third air duct 533. The third air duct 533 communicates with the third processing cylinder 3. Along the left-right direction of the casing 4, the third air duct 533 and the third processing cylinder 3 are located on the same side within the casing 4. It can be understood that the third air duct 533 and the third processing cylinder 3 can both be located on the left side or the right side within the casing 4, thereby shortening the extension path of the third air duct 533 and reducing the space occupied by the third air duct 533 within the casing 4.

[0073] For example, the third condenser 523 is located above the third evaporator 513. Both the third condenser 523 and the third evaporator 513 are located behind the third processing cylinder 3, thereby making use of the space behind the third processing cylinder 3.

[0074] Optionally, such as Figure 7 As shown, the third air duct 533 includes a third air outlet pipe 5331, a third intermediate pipe 5332, and a third air inlet pipe 5333. The third air outlet pipe 5331, the third intermediate pipe 5332, and the third air inlet pipe 5333 are connected in sequence. The third air outlet pipe 5331 and the third air inlet pipe 5333 both extend along the front-rear direction of the housing 4. The third air outlet pipe 5331 is located between the third processing cylinder 3 and the first processing cylinder 1. The third air inlet pipe 5333 is located on the upper side of the third processing cylinder 3. The third intermediate pipe 5332 extends along the vertical direction of the housing 4 and is located on the rear side of the third processing cylinder 3.

[0075] It is understandable that the third air outlet duct 5331 is located upstream of the third intermediate duct 5332, and the third intermediate duct 5332 is located upstream of the third air inlet duct 5333. That is, the air in the third treatment cylinder 3 can flow back into the third treatment cylinder 3 after passing through the third air outlet duct 5331, the third intermediate duct 5332 and the third air inlet duct 5333.

[0076] Since the third intermediate tube 5332 extends along the vertical direction of the housing 4 and is located behind the third processing cylinder 3, the third intermediate tube 5332 can make full use of the space behind the third processing cylinder 3 to optimize the arrangement of the components inside the housing 4 and reduce the overall size of the clothing processing equipment.

[0077] like Figure 7 As shown, the third evaporator 513 and the third condenser 523 are disposed on the third intermediate tube 5332, with the third condenser 523 located above the third evaporator 513. Exemplarily, both the third evaporator 513 and the third condenser 523 are located inside the third intermediate tube 5332. Since the third evaporator 513 and the third condenser 523 are disposed on the third intermediate tube 5332, which extends vertically, the third evaporator 513 and the third condenser 523 can fully utilize the space within the third intermediate tube 5332, resulting in a more compact structural arrangement of the third air duct 533, the third evaporator 513, and the third condenser 523, and higher heat exchange efficiency.

[0078] Optionally, the heat pump system 5 further includes a second fan 542 and a third fan 543. The second fan 542 is disposed in the second air duct 532, and the third fan 543 is disposed in the third air duct 533. The second fan 542 and the third fan 543 are located on the upper side of the first processing cylinder 1 and on the rear side of at least one of the second processing cylinder 2 and the third processing cylinder 3. The clothing processing device of this embodiment places the second fan 542 and the third fan 543 on the rear side of at least one of the second processing cylinder 2 and the third processing cylinder 3, which can fully utilize the rear space of the second processing cylinder 2 and / or the third processing cylinder 3, and is beneficial to reducing the size of the casing 4 in the vertical and horizontal directions.

[0079] For example, the second fan 542 is located on the rear side of the second processing cylinder 2, the third fan 543 is located on the rear side of the third processing cylinder 3, and the first fan 541 is located between the second fan 542 and the third fan 543.

[0080] Optionally, such as Figure 8 As shown, the first air duct 531 is located between the second air duct 532 and the third air duct 533. This allows for optimization of the arrangement of the first air duct 531, the second air duct 532, and the third air duct 533. On the one hand, it reduces the length of the first air duct 531, the second air duct 532, and the third air duct 533, lowering the complexity of the air duct design. On the other hand, since the first air duct 531 is located within the second air duct 532 and the third air duct 533, and their left-right arrangement is consistent with the arrangement of the first processing cylinder 1, the second processing cylinder 2, and the third processing cylinder 3, the arrangement of the first air duct 531, the second air duct 532, and the third air duct 533 is more regular, facilitating subsequent assembly of other components.

[0081] like Figure 9 As shown, the heat pump system 5 also includes a compressor 55. Evaporators (first evaporator 511, second evaporator 512, and third evaporator 513) and condensers (first condenser 521, second condenser 522, and third condenser 523) are all connected to the compressor 55 via refrigerant piping. It can be understood that there are three sets of refrigerant piping: one set connects to the first evaporator 511 and the first condenser 521; another set connects to the second evaporator 512 and the second condenser 522; and yet another set connects to the third evaporator 513 and the third condenser 523. It can be understood that the three sets of evaporators and condensers share one compressor 55. This reduces the number of components used, lowering the production cost of the clothing processing equipment. Furthermore, it saves space within the casing 4, allowing for a more compact arrangement of components within the casing 4.

[0082] It should be noted that the refrigerant pipeline connected to the compressor 55 is equipped with components such as an electronic expansion valve 56, a reversing valve, and a capillary tube, which will not be described in detail in this utility model.

[0083] For example, the compressor 55 is located above the first processing cylinder 1, so that the compressor 55 can make full use of the space above the first processing cylinder 1 and is close to the evaporator and condenser to facilitate the arrangement of refrigerant lines.

[0084] For example, the compressor 55 can be located behind the second processing cylinder 2 or the third processing cylinder 3, and positioned to the left or right of the second receiving area 42, so as to facilitate the arrangement of the evaporator, condenser and surrounding piping.

[0085] In this example of the present invention, the second processing cylinder 2 is located to the upper left of the first processing cylinder 1, and the third processing cylinder 3 is located to the upper right of the first processing cylinder 1, so that the second processing cylinder 2 and the third processing cylinder 3 can respectively utilize the space to the upper left and upper right of the first processing cylinder 1.

[0086] In other examples, the second processing cylinder 2 and the third processing cylinder 3 may be located simultaneously to the upper left of the first processing cylinder 1. Alternatively, the second processing cylinder 2 and the third processing cylinder 3 may be located simultaneously to the upper right of the first processing cylinder 1.

[0087] like Figure 1 As shown, the second processing cylinder 2 and the third processing cylinder 3 are located on the left and right sides of the first processing cylinder 1, respectively, and are arranged symmetrically from left to right. For example, the second processing cylinder 2 and the third processing cylinder 3 are symmetrical about a vertical plane passing through the axis of the first processing cylinder 1, or, for another example, the second processing cylinder 2 and the third processing cylinder 3 are symmetrical about a vertical plane passing through the center of the housing 4.

[0088] Therefore, the second processing cylinder 2 and the third processing cylinder 3 are roughly at the same horizontal height, and the distances of the second processing cylinder 2 and the third processing cylinder 3 from the axis of the first processing cylinder 1 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 allows the center of gravity of the three processing cylinders to be roughly located in the middle of the casing 4, which is beneficial to improving the stability of the clothing processing equipment during operation.

[0089] like Figure 1 As shown, the second processing cylinder 2 and the third processing cylinder 3 are the same size and shape. Therefore, during the assembly process of the garment processing equipment, the second processing cylinder 2 and the third processing cylinder 3 do not need to prepare their own materials, that is, the materials of the second processing cylinder 2 and the third processing cylinder 3 are interchangeable, thereby reducing production costs and facilitating subsequent maintenance and replacement.

[0090] In other examples, the size and shape of the second processing cylinder 2 and the third processing cylinder 3 may also be different, and this utility model does not limit this.

[0091] like Figure 1 and Figure 2 As shown, the axes of the second processing cylinder 2, the third processing cylinder 3, and the first processing cylinder 1 are all parallel to each other, and the inlets of the second processing cylinder 2, the third processing cylinder 3, and the first processing cylinder 1 are all arranged facing forward, which facilitates daily use by users.

[0092] like Figure 1 As shown, the capacity of either the second processing cylinder 2 or the third processing cylinder 3 is smaller than that of the first processing cylinder 1, 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.
