[0023] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0024] like Figure 1 As shown in the illustration, this application provides a cleaning device 100, which includes a housing 10, a cylindrical assembly 50 disposed within the housing 10, a drying module 20 disposed within the housing 10, and a steam generator module 40 disposed within the housing 10. The drying module 20 is used to supply high-temperature, low-humidity air to the interior of the cylindrical assembly 50 to dry the clothes inside the cylindrical assembly 50. The steam generator module 40 is used to supply high-temperature steam to the interior of the cylindrical assembly 50 to regulate the humidity inside the cylindrical assembly 50, preventing the clothes from becoming stiff or wrinkled after drying, and also assisting in removing odors.

[0025] The cleaning equipment 100 is positioned in a specific orientation during use. Based on this, such as Figure 1 As shown, three mutually perpendicular directions are defined in the cleaning device 100: up and down, left and right, and front and back. The up and down direction is determined by gravity. The left and right directions correspond to the left and right sides of the user's hand when using the cleaning device 100, respectively. The front direction corresponds to the side of the cleaning device 100 closest to the user, and the back direction corresponds to the side of the cleaning device 100 away from the user.

[0026] In addition, the up-down direction is usually understood as the height direction of the cleaning device 100, the left-right direction is usually understood as the width direction of the cleaning device 100, and the front-back direction is usually understood as the depth direction of the cleaning device 100.

[0027] like Figure 1As shown, the housing 10 includes a plurality of side plates 11 connected in sequence, the side plates 11 enclosing a space. Figure 1 Only a portion of the left-hand side plate 11 is shown to clearly illustrate the internal cylindrical assembly 50. The housing 10 also includes a top plate (not shown) and a bottom plate 12, the top plate being connected to the upper end of each side plate 11 and the bottom plate 12 being connected to the lower end of each side plate 11.

[0028] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the drying module 20 is disposed in the space enclosed by each side plate 11. Figure 2 The outline of the space is shown in a dashed box to reduce overlap between lines. The drying module 20 is fixedly connected to the side plate 11 within the space enclosed by the side plates 11 and is located on the upper side of the cylinder assembly 50. The steam generator module 40 is disposed within the space enclosed by the side plates 11 and is located on the upper side of the cylinder assembly 50. For example, Figure 2 and Figure 3 As shown, the steam generator module 40 includes at least one first connection part 421 and / or at least one second connection part 422. The first connection part 421 is connected to the drying module 20, and the second connection part 422 is connected to at least one side plate 11.

[0029] The cleaning equipment 100 provided in this application embodiment has a steam generator module 40 disposed on the upper side of the cylinder assembly 50, and connected to the drying module 20 through its first connecting part 421 and / or connected to the side plate 11 through its second connecting part 422. On the one hand, the steam generator module 40 can be exposed by removing the top plate, and the height of the steam generator module 40 is adapted to the height of maintenance personnel, making the steam generator module 40 easier to maintain. On the other hand, the steam generator module 40 is fixed by the adjacent drying module 20 and / or side plate 11, which further simplifies assembly and disassembly, while ensuring the stable installation of the steam generator module 40.

[0030] In some embodiments, the steam generator module 40 may include at least one first connection portion 421, which is connected to the drying module 20. The steam generator module 40 is fixed within the housing 10 by the drying module 20.

[0031] In some embodiments, the steam generator module 40 may include at least one second connection portion 422, which is connected to at least one side plate 11. The steam generator module 40 is secured within the housing 10 by at least one side plate 11.

[0032] In some embodiments, the steam generator module 40 may include at least one first connecting portion 421 and at least one second connecting portion 422. The first connecting portion 421 is connected to the drying module 20, and the second connecting portion 422 is connected to at least one side plate 11. The steam generator module 40 is connected to the side plate 11 and the drying module 20 at different locations, allowing the steam generator module 40 to be fixed at multiple points, further improving the installation stability of the steam generator module 40.

[0033] The following illustrations and descriptions will be based on an example where the steam generator module 40 includes both a first connecting part 421 and a second connecting part 422.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, the cleaning device 100 also includes a dispensing component 30, which is disposed on the housing 10 and located at a relatively forward and upper position on the housing 10. The dispensing component 30 is used by the user to dispense detergent into the drum assembly 50.

[0035] like Figure 2 As shown, to facilitate user operation, the dispensing component 30 is positioned relatively forward on the housing 10. In some embodiments of this application, the steam generator module 40 is located behind the dispensing component 30. Thus, the dispensing component 30 and the steam generator module 40 share the space above the cylinder assembly 50 in the front-to-back direction. The dispensing component 30 and the steam generator module 40 are arranged generally side-by-side in the front-to-back direction.

[0036] like Figure 2 As shown, in the width direction, the steam generator module 40 is located on one side of the drying module 20. Therefore, in the space above the cylinder assembly 50, the drying module 20 and the steam generator module 40 share this space in the left-right direction. In other words, the drying module 20 and the steam generator module 40 are arranged generally in a horizontal, side-by-side manner above the cylinder assembly 50.

[0037] In some embodiments of this application, such as Figure 2 As shown, in the width direction, the drying module 20 is located on one side of the dispensing component 30 and the steam generator module 40.

[0038] In this embodiment, the arrangement of the feeding component 30, the drying module 20 and the steam generator module 40 takes into full account the size of their projected area on the base plate 12, utilizes the limited space above the cylinder component 50, improves the utilization rate of the space inside the shell 10, and also enables the shell 10 to be kept at a suitable height as much as possible.

[0039] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the steam generator module 40 includes a water tank 41 and a steam generator 48 connected to each other. The internal space of the water tank 41 is used to store water, which enters the steam generator 48, is heated, and generates steam.

[0040] In some embodiments, the first connecting portion 421 and the second connecting portion 422 are disposed on the steam generator 48. Specifically, the steam generator 48 may include a steam generator body (not shown) and an insulation shell (not shown) disposed around the steam generator body. The first connecting portion 421 and the second connecting portion 422 may be disposed on the insulation shell, which facilitates the manufacturing of the first connecting portion 421 and the second connecting portion 422 and prevents the first connecting portion 421 and the second connecting portion 422 from leaking heat from the steam generator body.

[0041] In some embodiments of this application, the first connecting portion 421 and the second connecting portion 422 are disposed on the outer surface of the water tank 41. Compared to being disposed on the steam generator 48, the first connecting portion 421 and the second connecting portion 422 being disposed on the water tank 41 allows for convenient design of the required shape and size according to the installation requirements between the water tank 41 and the side plate 11 and the drying module 20. In some embodiments, the water tank 41 can be a single injection-molded part, with the first connecting portion 421 and the second connecting portion 422 integrally injection-molded onto the water tank 41.

[0042] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the drying module 20 includes an air inlet duct section 21 and an air outlet duct section 23 that are connected to each other. A first connecting part 421 is connected to at least one of the air inlet duct section 21 and the air outlet duct section 23. The air duct in the air inlet duct section 21 is used to output low-temperature, low-humidity air from inside the cylinder assembly 50, and the air duct in the air outlet duct section 23 can deliver high-temperature, low-humidity air into the cylinder assembly 50.

[0043] In some embodiments, the first connecting portion 421 is connected to the outer side of the air inlet duct portion 21 and / or the outer side of the air outlet duct portion 23. This includes the first connecting portion 421 being connected to the outer side of the air inlet duct portion 21, or the first connecting portion 421 being connected to the outer side of the air outlet duct portion 23, or the first connecting portion 421 being connected to both the outer sides of the air inlet duct portion 21 and the outer sides of the air outlet duct portion 23.

[0044] The drying module 20 also includes an air conditioning component disposed between the air inlet duct 21 and the air outlet duct 23 for converting the aforementioned low-temperature and low-humidity air into high-temperature and low-humidity air.

[0045] In some embodiments, such as Figure 2 and Figure 3As shown, the air conditioning component includes a heating assembly 22, which is disposed between the air inlet duct 21 and the air outlet duct 23. Figure 2 In this embodiment, the heating component 22 is connected to the air inlet duct 21 and the air outlet duct 23 via its external heating shell, forming an airflow path (here, the area where the heating shell is located is referred to as the heating component 22). After being heated by the heating component 22, the relative humidity of the low-temperature, low-humidity air decreases. The heating component 22 can be of various types. For example, it can include one or a combination of an electric heater and a condenser. In other embodiments, the heating component 22 can be replaced by a molecular sieve component. The molecular sieve component can absorb moisture from the air coming from the air inlet duct 21, and due to the adsorption of water molecules, kinetic energy is converted into internal energy, thus releasing some heat to heat the air passing through it. This application does not specifically limit the specific form of the air conditioning component described herein.

[0046] In some embodiments of this application, there are at least two first connecting portions 421, which are respectively connected to the external parts of the air inlet duct 21 and the air outlet duct 23. This arrangement ensures that the water tank 41 of the steam generator module 40 and the drying module 20 are fixedly connected at at least two points, which helps to guarantee the installation stability of the steam generator module 40 and its water tank 41. The following description uses the example of simultaneously providing two first connecting portions 421.

[0047] In some embodiments of this application, such as Figure 3 As shown, a first supporting portion 211 is provided on the outer side of the air inlet duct section 21, and a second supporting portion 231 is provided on the outer side of the air outlet duct section 23. A first connecting portion 421 is at least partially provided on the upper surface of the first supporting portion 211 and the upper surface of the second supporting portion 231, respectively. Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the first connecting part 421 is a protruding structure provided on the outer surface of the water box 41. The purpose of this arrangement is that the air inlet duct 21 and the air outlet duct 23 can support the first connecting part 421 respectively, further simplifying the connection and disassembly between the steam generator module 40 and the drying module 20. For example, the first connecting part 421 can be fixed to the air inlet duct 21 and the air outlet duct 23 in a simpler way, and if it is necessary to disassemble the steam generator module 40, the disassembly process is not interfered with by the drying module 20.

[0048] The form of the first support portion 211 and the second support portion 231 is not limited. In some embodiments, either the first support portion 211 or the second support portion 231 may include the form of a groove, a boss, a plane, etc.

[0049] In some embodiments of this application, such as Figure 2 As shown, a triangular space 24 is formed between the air inlet duct section 21 and the air outlet duct section 23, and at least a portion of the steam generator module 40 is disposed within the triangular space 24. Alternatively, the air inlet duct section 21 and the air outlet duct section 23 are not arranged in a straight line, but rather are connected at a relatively obvious angle or bend, with the steam generator module 40 disposed on the side where the two bends are closer together. The purpose of this arrangement is that, in the width direction of the cleaning equipment 100, the cylindrical assembly 50 is centrally located. Therefore, the air inlets of the air inlet duct section 21 and the air outlet duct section 23 are generally also centrally located. In this case, the angled air inlet duct section 21 and the air outlet duct section 23 allow the heating component 22 to be non-centrally located. Furthermore, above the cylindrical assembly 50, the heating component 22 can adapt to the space and have a larger volume and thickness.

[0050] In some embodiments, such as Figure 2 As shown, the heating component 22 is positioned on one side (taking the right side as an example), the air inlet duct 21 and the air outlet duct 23 are tilted to the left, and the steam generator module 40 is at least partially positioned in the triangular space 24 on the left side of the air inlet duct 21 and the air outlet duct 23.

[0051] In some embodiments of this application, at least one first connecting portion 421 has a lower surface and a side surface. The lower surface of the first connecting portion 421 is used to abut against the upper surface of the first supporting portion 211 and / or the second supporting portion 231, and the side surface of the first connecting portion 421 is used to abut against the side surface of the first supporting portion 211 and / or the second supporting portion 231. That is, in addition to abutting against the first supporting portion 211 and the second supporting portion 231 in the vertical direction, the first connecting portion 421 can also be positioned with the drying module 20 in the horizontal direction. In other words, in the horizontal direction, the position of the water box 41 and its first connecting portion 421 can be defined by the side surface of the first supporting portion 211 and / or the second supporting portion 231.

[0052] like Figure 3 As shown, in the left-right direction, the side of the first connecting portion 421 abuts against the side of the first supporting portion 211. In other embodiments, the side of the first connecting portion 421 may be inclined in other directions. In other embodiments, the side of the first connecting portion 421 may abut only against the first supporting portion 211 or only against the second supporting portion 231, depending on the shape of the outer side of the air inlet duct portion 21 and the air outlet duct portion 23.

[0053] In some embodiments of this application, at least one second connecting portion 422 has a lower surface and a side surface. The lower surface of the second connecting portion 422 is used to abut against the upper end surface of the side plate 11, and the included angle between the side surface and the lower surface of the second connecting portion 422 is an obtuse angle. Figure 6 As shown in the diagram. The purpose of this arrangement is that, on the side of the water tank 41 closest to the drying module 20, the side of the first connecting part 421 abuts against the side of the drying module 20 for positioning. On the side of the water tank 41 away from the drying module 20, the side of the second connecting part 422 does not directly abut against the inner side of the side plate 11, thus avoiding increasing the difficulty of horizontal positioning of the steam generator module 40 and its water tank 41. In actual installation, the side of the second connecting part 422 can serve as a guide surface 4220, such as... Figure 6 As shown, during the downward movement of the water box 41, the guide surface 4220 can guide the water box 41 to move toward the side (right side) of the drying module 20 until the water box 41 and the drying module 20 come into contact with each other, which means that the water box 41 is installed in place to the left.

[0054] The specific structures of the first connecting part 421 and the second connecting part 422 are not limited. For example, Figure 4 , Figure 5 and Figure 6 As shown, the first connecting portion 421 connected to the air outlet duct 23 is flat, and the first connecting portion 421 and the second connecting portion 422 connected to the air inlet duct 21 have certain three-dimensional dimensions. For the first connecting portion 421 and the second connecting portion 422 connected to the air inlet duct 21, in order to balance their strength, weight, and materials, the first connecting portion 421 and the second connecting portion 422 connected to the air inlet duct 21 can be configured to include multiple spaced-apart fins 423.

[0055] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the water tank 41 and the steam generator 48 are arranged along the width direction of the housing 10, and, as Figure 6 As shown, in the direction towards the cylinder assembly 50, that is, in the downward direction, the bottom of the water box 41 protrudes more than the bottom of the steam generator 48. This arrangement is intended to ensure that the upper surface of the cylinder assembly 50 is curved, thus the space directly above the center of the cylinder assembly 50 has a smaller height, while the space near the left and right sides has a larger height. Here, the water box 41 and the steam generator 48 are arranged along the width of the housing 10, so that the steam generator 48 is roughly positioned directly above the center of the cylinder assembly 50, while the water box 41 can be located to the left or right of the steam generator 48, etc. The water box 41 can have a larger height and volume, reducing the frequency of water intake and replenishment during steam generation.

[0056] The water tank 41 can be manually filled. For example, a portion of the water tank 41 can be positioned forward, close to, flush with, or protrude from the front side panel 11. Or, as... Figure 4 and Figure 5 As shown, the water box 41 can automatically receive water by connecting to an external water source through a water valve (not shown) via a water inlet pipe 471.

[0057] like Figure 3 , Figure 4 and Figure 5 As shown, the steam generator module 40 also includes a steam outlet pipe 475, one end of which is connected to the steam generator 48, and the other end can be directly or indirectly connected to the interior of the cylinder assembly 50.

[0058] In some embodiments of this application, such as Figure 3 , Figure 4 and Figure 5 As shown, the steam generator module 40 also includes an overflow pipe 474. One end of the overflow pipe 474 is located on the upper surface of the water box 41 and communicates with the water box 41, while the other end of the overflow pipe 474 is connected to the air outlet duct 23. The overflow pipe 474 is used to drain excess water when the water level in the water box 41 is too high. Specifically, the excess water can be drained into the interior of the cylinder assembly 50 through the air outlet duct 23. This avoids the need to create an additional hole in the cylinder assembly 50 for the overflow pipe 474 to pass through.

[0059] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the drying module 20 also includes an air duct adapter 230, which is connected between the air outlet duct section 23 and the cylinder assembly 50. The other end of the overflow pipe 474 is connected to the air duct adapter 230. In some other embodiments, the other end of the overflow pipe 474 can be directly connected to the air outlet duct section 23.

[0060] In other embodiments, the other end of the overflow pipe 474 may pass through the cylindrical assembly 50, including the overflow pipe 474 being able to pass through the cylindrical assembly 50 alone or together with other pipes.

[0061] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the upper side of the water box 41 is provided with a receiving groove 410, and the steam generator 48 is at least partially disposed in the receiving groove 410. The receiving groove 410 and the steam generator 48 are integrated together, which is beneficial to the reduction of the overall volume of the steam generator module 40 and the full utilization of the irregular space inside the housing 10 and above the cylinder assembly 50.

[0062] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the steam generator module 40 also includes a water pump 49, which is connected between the water box 41 and the steam generator 48. The water pump 49 is located in the receiving tank 410. Therefore, the water pump 49, the receiving tank 410 and the steam generator 48 are integrated together, which can also support and protect the water pump 49 at the same time.

[0063] In some embodiments of this application, such as Figure 4 , Figure 5 and Figure 7 As shown, the steam generator module 40 also includes a return water pipe 473. One end of the return water pipe 473 is connected to the water box 41, and the other end of the return water pipe 473 is connected between the water pump 49 and the steam generator 48. When the water pump 49 fails to stop pumping water or the steam generator 48 becomes blocked, water can flow back to the water box 41 before the steam generator 48, and excess water is further discharged through the overflow pipe 474.

[0064] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the bottom wall of the receiving tank 410 is provided with a plurality of first reinforcing ribs 4101. The first reinforcing ribs 4101 are used to ensure the strength of the inner bottom wall of the receiving tank 410, so that the inner bottom wall of the receiving tank 410 will not be deformed under pressure when supporting the steam generator 48.

[0065] In some embodiments of this application, such as Figure 6 As shown, the water box 41 includes a first box body portion 411 and a second box body portion 412 disposed below the first box body portion 411; wherein, as Figure 5 As shown, the first box body 411 has a first cavity 4110, and the second box body 412 has a second cavity 4120, as... Figure 5 As shown, the first cavity 4110 and the second cavity 4120 are connected vertically; the cross-sectional area (cross-sectional area along the horizontal plane) of the first box portion 411 is larger than the cross-sectional area of ​​the second box portion 412. That is to say, the water box 41 has a larger upper half and a smaller lower half. The purpose of this design is that the bottom of the water box 41 is not flat, so it can be adapted to the uneven space above the cylindrical assembly 50. While ensuring a safe distance between the water box 41 and the upper surface of the cylindrical assembly 50, the water box 41 can have the largest possible volume.

[0066] The first box portion 411 and the second box portion 412 are divided based on the shape of the water box 41. When manufacturing the water box 41, in order to enable the water box 41 to form a generally closed structure, it can be divided from other positions, including at least a third box portion 413 and a fourth box portion 414, based on ease of processing and molding. The third box portion 413 and the fourth box portion 414 are joined together, defining the water box 41, as shown below. Figure 5 , Figure 7 and Figure 8 As shown. In some embodiments, the third box portion 413 and the fourth box portion 414 are joined vertically. The fourth box portion 414 includes the second box portion 412 and the lower portion of the first box portion 411, generally forming the main body of the water box 41. The third box portion 413 includes the upper portion of the first box portion 411, generally forming the top cover of the water box 41. In other embodiments, the third box portion 413 and the fourth box portion 414 may be divided in other ways.

[0067] The receiving slot 410 can be specifically provided on the second box body 412, such as Figure 6 As shown.

[0068] Depending on the different division methods of the third box portion 413 and the fourth box portion 414, the receiving groove 410 can be provided on either the third box portion 413 or the fourth box portion 414. For example... Figure 5 As shown, the receiving groove 410 is provided on the fourth box body 414, the third box body 413 is provided to avoid the receiving groove 410 and is connected to the other parts of the fourth box body 414.

[0069] like Figure 6 As shown, at the bottom of the water box 41, one or more second reinforcing ribs 424 are provided on the outer wall of the connection between the first box body 411 and the second box body 412. The second reinforcing ribs 424 are used to increase the strength of the connection between the first box body 411 and the second box body 412.

[0070] In some embodiments of this application, the first box portion 411 has an inner bottom wall, and its inner bottom wall is connected to the upper end of the second box portion 412. The inner bottom wall of the first box portion 411 gradually slopes downward in the direction toward the second box portion 412. After the water in the water box 41 is gradually drawn into the steam generator 48, the water level in the water box 41 gradually decreases, and water will not remain on the inner bottom wall of the first box portion 411.

[0071] like Figure 5 and Figure 7As shown, the inner bottom wall of the first box body portion 411 includes a first inner bottom wall 4111, which is gradually inclined downwards in the direction toward the second box body portion 412. Specifically, the first inner bottom wall 4111 is located on one side of the second box body portion 412 in the front-rear direction. Figure 5 In the middle, on the front side, the first inner bottom wall 4111 gradually slopes downwards from front to back, as... Figure 7 As shown.

[0072] In some embodiments of this application, such as Figure 7 As shown, the steam generator module 40 also includes a liquid level detection component 46. The liquid level detection component 46 includes a float 461 that floats with the liquid surface, a first detection element 462, and a second detection element 463. The first detection element 462 is located on the upper surface of the water tank 41, and the second detection element 463 is located on the lower surface of the water tank 41. A guide post 416 is provided inside the water tank 41, arranged vertically, and the float 461 is slidably sleeved on the guide post 416. When the float 461 rises with the liquid surface and approaches the first detection element 462, and the first detection element 462 detects the float 461, it indicates that the water level in the water tank 41 has reached a high preset position. When the float 461 falls with the liquid surface and approaches the second detection element 463, and the second detection element 463 detects the float 461, it indicates that the water level in the water tank 41 has reached a low preset position. The form of the first detection element 462 and the second detection element 463 is not limited and can be a reed switch. In other embodiments, the first detection element 462 and the second detection element 463 may also be Hall devices, etc.

[0073] In some embodiments of this application, such as Figure 4 , Figure 5 and Figure 7 As shown, the water box 41 is also equipped with a water inlet 417, such as Figure 5 and Figure 7 As shown, a partition plate 415 is provided on the inner wall of the water box 41. The partition plate 415 is located between the water inlet 417 and the float 461 to form a bent flow channel between the water inlet 417 and the float 461. The purpose of this arrangement is to isolate the water inlet 417 and the float 461 through the partition plate 415, so as to avoid the water flow at the water inlet 417 causing large fluctuations in the float 461. After passing through the partition plate 415, the water reaches the float 461 in a more gentle manner, which can improve the accuracy of liquid level detection.

[0074] In some embodiments of this application, such as Figure 5 and Figure 7As shown, in the width direction of the housing 10, the inlet 417 and the float 461 are located on both sides of the partition plate 415. The purpose of this arrangement is that the partition plate 415 can have a large length (referring to the dimension in the front-to-back direction), and the path from the inlet 417 to the float 461 is longer, so that the water can become significantly calmer.

[0075] like Figure 5 and Figure 8 As shown, in some embodiments of this application, the second housing portion 412 has a second inner bottom wall 4122, which is located on the side of the partition plate 415 near the water inlet 417 and gradually slopes downward in the direction toward the float 461. The purpose of this arrangement is that, on the one hand, in the width direction of the housing 10, the slope direction of the inner bottom wall of the second housing portion 412 also matches the arc shape of the upper side of the cylindrical assembly 50; on the other hand, the second inner bottom wall 4122 also allows the water from the water inlet 417 to flow downward as much as possible and reach the lowest point of the second housing portion 412.

[0076] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the steam generator module 40 also includes a water outlet pipe 472 and a water inlet pipe 418. One end of the water outlet pipe 472 is connected to the water outlet 4130 on the upper surface of the water box 41, specifically the water outlet 4130 located on the third box body 413. The other end of the water outlet pipe 472 is connected to the steam generator 48. The water inlet pipe 418 is located inside the water box 41, with its upper end connected to the water outlet 4130 and its lower end located near the inner bottom wall of the water box 41. That is, the water outlet pipe 472 can be located on the upper side of the water box 41, and the location of the water inlet pipe 418 inside the water box 41 ensures that water at the lowest point inside the water box 41 can also be drawn by the water pump 49. This can reduce water residue in the water box 41 and avoid problems such as the formation of a large amount of scale and water deterioration.

[0077] The water inlet pipe 418 can be integrally formed with the third box body 413, or it can be separately formed with the third box body 413 and connected together. The bottom end of the water inlet pipe 418 can be as close as possible to the inner wall of the lowest position of the water box 41, as long as water can enter the water inlet pipe 418.

[0078] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
