Description

Technical Field

[0001] This invention relates to the field of electrical technology, and more particularly to a cooking appliance. Background Technology

[0002] Nowadays, cooking appliances are becoming increasingly integrated, typically incorporating multiple cooking functions such as steaming, microwaving, and grilling. Due to their high degree of integration, they can save kitchen space, and these appliances can select cooking functions based on the needs of different foods, thus meeting user requirements.

[0003] Cooking appliances with a steam function are generally equipped with a water tank and a wastewater box. The water tank provides clean water to the steam generator, while the wastewater box collects condensate and other wastewater generated during cooking. Existing cooking appliances have the following drawbacks: 1. To reduce kitchen space requirements, the size of the appliance is limited, resulting in a limited water tank capacity, typically around 1000ml. When using steam cooking functions, the water tank often runs out of power, requiring regular refills; 2. The wastewater box also has a limited capacity, easily overflowing and requiring regular emptying. Summary of the Invention

[0004] The purpose of this invention is to provide a cooking appliance that can be directly connected to an external water source and discharge wastewater to the outside of the cooking appliance, thus avoiding frequent water additions and wastewater cleaning.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A cooking appliance is provided, comprising:

[0016] A portion of the second drain pipe and a portion of the second inlet pipe are secured to one of the pipe clamping assemblies.

[0017] As a preferred embodiment of a cooking appliance, the second direction is horizontal, and the clamping assembly includes a water inlet clamping groove and a drain clamping groove, which are spaced apart along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0018] As a preferred embodiment of the cooking appliance, the lengths of the water inlet slot and the drain slot extend along the second direction, and both the water inlet slot and the drain slot slope downwards from the end near the water inlet connector toward the end away from the water inlet connector; and / or,

[0019] The length of the plate body extends along the second direction, and the ends of the water inlet slot and the water outlet slot away from the water inlet connector both penetrate the end of the plate body along its length direction.

[0020] As a preferred embodiment of a cooking appliance, the plate body is provided with a first protrusion, a second protrusion, and a third protrusion, which are spaced apart along the third direction. A water inlet groove is formed between the first and second protrusions, and a drain groove is formed between the second and third protrusions; and / or,

[0021] At least two limiting components are spaced apart in both the water inlet slot and the drain slot along the second direction. Each limiting component includes a first limiting plate and a second limiting plate spaced apart along the third direction. The side of the first limiting plate facing the second limiting plate has a first limiting groove, and the side of the second limiting plate facing the first limiting plate has a second limiting groove. The first limiting groove and the second limiting groove are arranged opposite to each other to form a limiting hole that restricts the external water inlet pipe or the external drain pipe. A connecting channel is formed between the first limiting plate and the second limiting plate that connects the outside to the limiting hole. The size of the connecting channel is smaller than the maximum size of the limiting hole along the third direction.

[0022] As a preferred embodiment of a cooking appliance, the water pipe support is detachably connected to the housing; and / or,

[0023] The water pipe support is located on the rear side of the box and adjacent to the bottom surface of the box.

[0024] As a preferred embodiment of the cooking appliance, the rear side of the cabinet is recessed with a groove, the bottom and opening of the groove are distributed along the arrangement direction of the front and rear sides of the cabinet, and the groove penetrates the bottom surface of the cabinet vertically. The water pipe support is disposed in the groove, and the side of the water pipe support away from the bottom of the groove is lower than or flush with the opening of the groove.

[0030] As a preferred embodiment of cooking appliances, the wastewater box has a wastewater outlet on its side, which is connected to the second water pipe, and a slag-blocking mechanism is provided inside the wastewater box corresponding to the wastewater outlet.

[0031] The beneficial effects of this invention are:

[0032] The cooking appliance of this invention, by incorporating an external water inlet pipe, allows water from outside the appliance (such as tap water or water from a water purifier) ​​to be directly supplied to the water tank. The water tank then supplies the water to the steam generator to produce steam. The entire process eliminates the need for frequent water replenishment. The water inlet valve is connected to the controller of the cooking appliance, which automatically controls the water supply as needed. Furthermore, since the external water inlet pipe is connected to the water tank first, the water tank can release the water pressure from the external water inlet pipe before supplying water to the steam generator. This effectively prevents water with high or fluctuating pressure from directly entering the steam generator, thus preventing damage to the steam generator. By incorporating a wastewater box, wastewater from the cooking chamber and the steam generator can be collected. When the steam generator is not used for a short period, the drain valve connected to the controller opens, draining the water from the steam generator into the wastewater box, preventing wastewater residue in the cooking chamber and the steam generator, thereby preventing bacterial growth. The external drain pipe allows the water collected in the wastewater box to be directly discharged to the outside of the cooking appliance (as a drain pipe), effectively avoiding frequent cleaning of the wastewater box. The cooking appliance of the present invention can automatically fill and drain water, and is easy to operate. Attached Figure Description

[0060] See attached document Figures 1 to 4As shown, the cooking appliance 100 of this embodiment includes a housing 1, a steam generating assembly 2, an external water inlet pipe 3, an external drain pipe 4, a wastewater box 5, and a controller (not shown in the figure). The housing 1 has a cooking chamber with a steam inlet. The steam generating assembly 2 is mounted on the housing 1 and includes a steam generator 21, a first water pipe 22, a water tank 23, a steam conduit 24, a second water pipe 25, and a drain valve 26. The water inlet of the steam generator 21 is connected to the water tank 23 via the first water pipe 22, and the steam outlet of the steam generator 21 is connected to the steam inlet via the steam conduit 24. The outlet of the steam generator 21 is connected to the second water pipe 25. The drain valve 26 is installed on the second water pipe 25. The external water inlet pipe 3 is connected to the water tank 23 and is used to transport water from outside the cooking appliance 100 to the water tank 23. The external water inlet pipe 3 is equipped with an inlet valve. The wastewater box 5 is installed at the bottom of the box 1 and is used to collect wastewater generated in the cooking cavity. The end of the second water pipe 25 away from the steam generator 21 is connected to the wastewater box 5. One end of the external drain pipe 4 is connected to the wastewater box 5, and the other end is used to discharge the wastewater in the wastewater box 5 to the outside of the cooking appliance 100. The controller is connected to the steam generator 21, the drain valve 26 and the inlet valve.

[0061] The cooking appliance 100 of the present invention, by providing an external water inlet pipe 3, enables water from outside the cooking appliance 100 (the water outside the cooking appliance 100 can be tap water or other types of water) to flow into the appliance. Figure 6 The water from the water purifier 300 shown can be directly delivered to the water tank 23, which then sends the water to the steam generator 21 to produce steam. The entire process does not require frequent water replenishment. The inlet valve is connected to the controller of the cooking appliance 100, which automatically controls the water supply as needed. Furthermore, since the external water inlet pipe 3 is first connected to the water tank 23, the water tank 23 can release the water pressure from the external water inlet pipe 3 before sending the water to the steam generator 21. This effectively avoids direct water flow under high pressure or fluctuating water pressure. The water is fed into the steam generator 21, effectively preventing damage to the steam generator 21. The wastewater box 5 collects wastewater from the cooking chamber and the steam generator 21. When the steam generator 21 is not used for a short period, the drain valve 26 connected to the controller opens, draining the water from the steam generator 21 into the wastewater box 5, preventing wastewater residue in the cooking chamber and the steam generator 21, thus preventing bacterial growth. The external drain pipe 4 allows the water collected in the wastewater box 5 to be directly discharged to the outside of the cooking appliance 100 (e.g., ...). Figure 6 The kitchen drain pipe 400 shown effectively avoids frequent cleaning of the wastewater box 5. The cooking appliance 100 of this invention can achieve automatic water inlet and drainage, and is simple to operate.

[0062] The program within the controller of the cooking appliance 100 is existing technology that is readily available to those skilled in the art, so it will not be described in detail here. The various components connected to the controller can automatically achieve control according to the set program.

[0063] In this embodiment, the housing 1 has a hexahedral structure with a hollow interior forming a cooking chamber. The housing 1 has a front side, a rear side, a left side 14, a right side, a top surface 12, and a bottom surface 13. An opening is provided on the front side of the housing 1, and a door 7 is provided at the opening to seal it. A wastewater box 5 is located on the bottom surface 13 of the housing 1. The wastewater box 5 has an upward-facing water inlet 51, with at least a portion of the water inlet 51 located below the connection between the housing 1 and the door 7. Generally, after cooking food, steam from the cooking appliance 100 condenses into water droplets near the door 7 and the opening of the housing 1. These droplets flow along the door 7 and the opening of the housing 1 to the connection between the housing 1 and the door 7. Placing the wastewater box 5 in this location allows water to flow into the wastewater box 5 for collection, preventing water from flowing onto the countertop where the cooking appliance 100 is placed (e.g., ...). Figure 6 The stovetop shown (200) reduces the difficulty of cleaning.

[0064] Preferably, the inlet 51 of the wastewater box 5 covers the entire top of the wastewater box 5, and the vertical projection of the connection between the box body 1 and the box door 7 is entirely located within the inlet 51, so as to ensure that the water at this location can completely enter the wastewater box 5 for collection through the inlet 51.

[0065] In addition, since water (water produced after steam condensation) will also accumulate in the cooking chamber of the box 1, a drain outlet can be opened at the bottom of the cooking chamber and connected to the wastewater box 5 through a pipe, so that the water in the cooking chamber can be discharged into the wastewater box 5.

[0066] In one embodiment, such as Figure 4 As shown (some of the reference numerals in the attached figures are retained), Figures 1 to 3 A water level sensor 27 is installed inside the water tank 23, and the water level sensor 27 is connected to the controller. By setting the water level sensor 27, the minimum water level in the water tank 23 can be monitored in real time. When the water level in the water tank 23 is too low, the water level sensor 27 will send a feedback signal to the controller, and the controller will control the water inlet valve to open, and the external water inlet pipe 3 will introduce external water into the water tank 23 to replenish the water. Water level sensors 27 can be installed at both the minimum and maximum water levels to avoid overfilling the water tank 23.

[0067] Optionally, the water tank 23 is also provided with an overflow outlet, which is connected to the wastewater box 5 via an overflow pipe. With the overflow outlet, when too much water is added to the water tank 23, the excess water will flow from the overflow outlet and the overflow pipe to the wastewater box 5.

[0068] Optionally, a drain pipe is also provided on the water tank 23. The drain pipe is located at the bottom of the water tank 23 and is connected to the wastewater box 5 for draining the water in the water tank 23. When the cooking appliance 100 is not used for a long time, all the water in the water tank 23 can be drained to prevent the water in the water tank 23 from deteriorating due to prolonged storage. The drain pipe can also assist in cleaning the water tank 23 after a period of use, preventing the water in the water tank 23 from accumulating impurities and becoming contaminated over time.

[0069] In one embodiment, such as Figure 1 As shown (some of the reference numerals in the attached figures are retained), Figures 2 to 4 The first water pipe 22 is connected to the water tank 23 via a water pump 28. By setting the water pump 28, the placement of the water tank 23 is not restricted; the water tank 23 can be positioned lower than the steam generator 21. For example, the water tank 23 can be located on the bottom surface 13 of the housing 1, and the steam generator 21 can be located on the left or right side of the water tank 23. This allows space-consuming components to be distributed on different sides of the housing 1, enabling a reasonable layout of the components on the housing 1 and preventing the cooking appliance 100 from becoming too large. In this embodiment, the water pump 28 is also connected to a controller to achieve automatic control.

[0070] In addition, both the inlet valve and the drain valve 26 are solenoid valves.

[0071] In one embodiment, such as Figures 1 to 5As shown, a water pipe support 6 is provided on the housing 1. The water pipe support 6 includes a plate body 61, a water inlet connector 62, and a drain connector 63. Both the water inlet connector 62 and the drain connector 63 are right-angle pipe connectors. One end of the water inlet connector 62 passes through the plate body 61 and is rotatably connected to the plate body 61. One end of the drain connector 63 passes through the plate body 61 and is rotatably connected to the plate body 61. The rotation center axes of the water inlet connector 62 and the drain connector 63 are parallel, and the rotation center axes of the water inlet connector 62 and the drain connector 63 both extend along a first direction. Pipe clamping assemblies are provided on both sides of the water inlet connector 62 and the drain connector 63 along a second direction on the plate body 61. The components are arranged at an angle between the first direction and the second direction; the external drain pipe 4 includes a first drain pipe and a second drain pipe, the two ends of the first drain pipe are respectively connected to one end of the drain connector 63 and the wastewater box 5; the two ends of the second drain pipe are respectively connected to the other end of the drain connector 63 and the outside of the cooking appliance 100; the external water inlet pipe 3 includes a first water inlet pipe and a second water inlet pipe, the two ends of the first water inlet pipe are respectively connected to one end of the water inlet connector 62 and the water tank 23; the two ends of the second water inlet pipe are respectively connected to the other end of the water inlet connector 62 and the outside of the cooking appliance 100; a portion of the second drain pipe and a portion of the second water inlet pipe are clamped onto one of the pipe clamping components. By setting up the water pipe support 6, the direction of the pipe connection can be adjusted through the rotatable inlet connector 62 and drain connector 63 on the water pipe support 6. This allows the external water inlet pipe 3 and external drain pipe 4 to be adjusted according to the on-site requirements, reducing the difficulty of pipe laying during on-site installation of the cooking appliance 100 and increasing the installation speed. By setting pipe clamping components on both sides of the inlet connector 62 and drain connector 63 along the second direction, the portions of the external water inlet pipe 3 and external drain pipe 4 adjacent to the inlet connector 62 and drain connector 63 can be clamped and fixed after the pipe connection direction is adjusted, avoiding pipe clutter. In addition, since the two pipe clamping components are arranged at intervals along the second direction, the inlet connector 62 and drain connector 63 can not only rotate towards the pipe clamping components, but also rotate towards the area between the two pipe clamping components, allowing the inlet connector 62 and drain connector 63 to adapt to the requirements of multiple pipe laying directions.

[0072] In this embodiment, the second direction is horizontal. The pipe clamping assembly includes an inlet clamping groove 64 and a drain clamping groove 65, which are spaced apart along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. By setting the inlet clamping groove 64 and the drain clamping groove 65, the external water inlet pipe 3 and the external drain pipe 4 can be clamped and fixed. The clamping groove structure is simple, and the external water inlet pipe 3 and the external drain pipe 4 are not only easy to fix, but also easy to disassemble, effectively reducing the difficulty of operation. Setting the second direction to horizontal allows the external water inlet pipe 3 and the external drain pipe 4 to be arranged horizontally from the housing 1 of the cooking appliance 100, reducing the difficulty of arrangement.

[0073] Furthermore, the water pipe support 6 is located on the rear side of the housing 1 and adjacent to the bottom surface 13 of the housing 1. By placing the water pipe support 6 at a lower position on the rear side of the housing 1, the external water inlet pipe 3 and the external drain pipe 4 on the water pipe support 6 can be hidden, preventing the pipes from being exposed, and thus preventing the external water inlet pipe 3 and the external drain pipe 4 from being pulled out at will.

[0074] In this embodiment, the lengths of the inlet slot 64 and the drain slot 65 extend along the second direction, and both the inlet slot 64 and the drain slot 65 are inclined downwards from the end near the inlet connector 62 toward the end away from the inlet connector 62. The inclined arrangement of the inlet slot 64 and the drain slot 65 ensures that the area where the external inlet pipe 3 and the external drain pipe 4 are engaged on the water pipe support 6 is inclined, thus ensuring that the water on the external drain pipe 4 can be discharged as cleanly as possible, preventing wastewater from remaining in the external drain pipe 4 and causing bacteria to grow. The inclined arrangement of the external inlet pipe 3 can also reduce some of the water pressure entering the water tank 23.

[0075] Furthermore, the length of the plate body 61 extends along the second direction, and the ends of the water inlet slot 64 and the drain slot 65 away from the water inlet connector 62 both penetrate the end of the plate body 61 along its length. This design allows the water inlet slot 64 and the drain slot 65 to be led out from the left and right sides of the housing 1, as well as from the bottom of the plate body 61, adapting to the needs of various installation environments.

[0076] In this embodiment, a first protrusion 66, a second protrusion 67 and a third protrusion 68 are provided on the plate body 61. The first protrusion 66, the second protrusion 67 and the third protrusion 68 are spaced apart along a third direction. A water inlet groove 64 is formed between the first protrusion 66 and the second protrusion 67, and a drainage groove 65 is formed between the second protrusion 67 and the third protrusion 68.

[0077] In this embodiment, the plate body 61 is a sheet metal part. A first protrusion 66, a second protrusion 67, and a third protrusion 68 are stamped onto the plate body 61. These stamped protrusions not only form the water inlet groove 64 and the drain groove 65, but also improve the overall strength of the water pipe support 6 without increasing the thickness of the plate body 61. In other embodiments, the water pipe support 6 may also be formed by integral injection molding of the first protrusion 66, the second protrusion 67, and the third protrusion 68 from plastic.

[0078] A water inlet pipe hole 611 is provided on the plate body 61 at the position corresponding to the water inlet connector 62, and a drain pipe hole 612 is provided at the position corresponding to the drain connector 63. The water inlet connector 62 passes through the water inlet pipe hole 611 and is rotatably connected to the plate body 61, and the drain connector 63 passes through the drain pipe hole 612 and is rotatably connected to the plate body 61.

[0079] At least two limiting components 69 are provided at intervals along the second direction in both the water inlet slot 64 and the drain slot 65. That is, multiple limiting components 69 are provided in the water inlet slot 64 and multiple limiting components 69 are provided in the drain slot 65. The limiting component 69 includes a first limiting plate 691 and a second limiting plate 692 provided at intervals along the third direction. The side of the first limiting plate 691 facing the second limiting plate 692 has a first limiting groove 693 recessed inward. The side of the second limiting plate 692 facing the first limiting plate 691 has a second limiting groove 694 recessed inward. The first limiting groove 693 and the second limiting groove 694 are arranged opposite to each other to form a limiting hole 690 that restricts the external water inlet pipe 3 or the external drain pipe 4. A connecting channel 695 is formed between the first limiting plate 691 and the second limiting plate 692 to connect the outside and the limiting hole 690. The size of the connecting channel 695 is smaller than the maximum size of the limiting hole 690 along the third direction. By setting the limiting component 69, the water pipe (external inlet pipe 3 and external outlet pipe 4) can be well restricted when it is stuck in the slot (inlet slot 64 and outlet slot 65). The diameter of the water pipe is slightly larger than the size of the connecting channel 695. The water pipe is a flexible tube. After being flattened, it enters the limiting hole 690 from the narrower connecting channel 695. After its deformation recovers, it can be restricted in the limiting hole 690, effectively preventing the water pipe from falling out of the slot.

[0080] In this embodiment, both the first limiting groove 693 and the second limiting groove 694 are arc grooves. The groove wall of the first limiting groove 693 extends to connect with the upper groove wall of the card slot along the third direction, and the groove wall of the second limiting groove 694 extends to connect with the lower groove wall of the card slot along the third direction. The first limiting groove 693, the second limiting groove 694, the bottom of the card slot, and the two groove walls together form a space that restricts the water pipe.

[0081] In other embodiments, instead of being limited to the first limiting groove 693 recessed on the first limiting plate 691 and the second limiting groove 694 recessed on the second limiting plate 692, an inclined surface can also be provided on the side of the first limiting plate 691 near the second limiting plate 692, and an inclined surface can also be provided on the side of the second limiting plate 692 near the first limiting plate 691. The inclined surface on the first limiting plate 691 slopes upward from the end near the second limiting plate 692 toward the bottom of the groove, and the inclined surface on the second limiting plate 692 slopes downward from the end near the first limiting plate 691 toward the bottom of the groove. The two inclined surfaces form an "eight"-shaped limiting structure for locking the water pipe.

[0082] In one embodiment, the water pipe support 6 is detachably connected to the housing 1. By detachably connecting the water pipe support 6 to the housing 1, the manufacturing difficulty of the water pipe support 6 can be reduced, and different types (i.e., different forms and different numbers of inlet slots 64 and drain slots 65) can be replaced as needed to adapt to different installation requirements.

[0083] In this embodiment, the water pipe support 6 is detachably connected to the housing 1 by screws. Of course, it is not limited to fixing the water pipe support 6 with screws; a snap-fit ​​structure can also be provided to directly snap the water pipe support 6 onto the housing 1, or a magnetic structure can be provided to magnetically attach the water pipe support 6 to the housing 1.

[0084] In one embodiment, such as Figures 1 to 3 , Figure 5 As shown, the rear side of the box 1 has a recessed groove 15. The bottom and opening of the groove 15 are distributed along the arrangement direction of the front and rear sides of the box 1. The groove 15 penetrates the bottom surface 13 of the box 1 in the vertical direction. The water pipe support 6 is set in the groove 15. The side of the water pipe support 6 away from the bottom of the groove 15 is lower than the opening of the groove 15 or flush with the opening of the groove 15.

[0085] The rear side of the housing 1 is provided with a rear guard plate 11, and the water pipe support 6 is located below the rear guard plate 11. The side of the water pipe support 6 away from the bottom of the groove 15 is flush with the rear guard plate 11.

[0086] Because the cooking appliance 100 of the present invention is equipped with a water pipe support 6, it can be applied to multiple installation environments, such as... Figure 6 and Figure 7 As shown, the cooking appliance 100 can be placed on the stove 200. A stove hole 210 is opened on the stove 200 near the wall. The cooking appliance 100 is arranged against the wall. The external water inlet pipe 3 and the external drain pipe 4 are led out from the left side 14 of the cooking appliance 100, and then enter the lower part of the stove 200 through the stove hole 210. The external water inlet pipe 3 is connected to the water purifier 300 under the stove 200, and the external drain pipe 4 is inserted into the drain pipe 400.

[0087] like Figure 8 and Figure 9 As shown, the cooking appliance 100 is installed on the stove 200. If the stove 200 does not have a pre-drilled stove hole 210, the cooking appliance 100 can be placed against the wall and placed at one end of the stove 200. In this case, the external water inlet pipe 3 and the external drain pipe 4 are led out from the right side of the cooking appliance 100 and then extended downward to the stove bottom groove 220 near the ground of the stove 200. They are then led along the stove bottom groove 220 to the water purifier 300 and the drain pipe 400 below the stove 200. The external water inlet pipe 3 is connected to the water purifier 300 below the stove 200, and the external drain pipe 4 is inserted into the drain pipe 400.

[0088] As can be seen, the rotatable inlet connector 62 and drain connector 63 on the water pipe support 6, combined with the inlet slot 64, drain slot 65 and limiting component 69, can adjust the position of the outlet pipe according to the needs of on-site installation. This design can avoid drilling holes when there are no holes on the stove 200, reducing the difficulty of operation.

[0089] In one embodiment, such as Figure 10 and 11 As shown (some of the reference numerals in the attached figures are retained), Figure 1 , 3 4) A wastewater outlet is provided on the side of the wastewater box 5, which is connected to the second water guide pipe 25. A slag-blocking mechanism 52 is provided inside the wastewater box 5 corresponding to the wastewater outlet. By setting the slag-blocking mechanism 52, impurities in the wastewater box 5 can be blocked and retained inside the wastewater box 5, making it easy to clean, and can also effectively prevent impurities from entering the second water guide pipe 25 and clogging it.

[0090] In this embodiment, the slag-blocking mechanism 52 includes a plurality of slag-blocking ribs 520. The wastewater outlet is located on the side wall of the wastewater box 5 and adjacent to the bottom of the wastewater box 5. The lower end of the slag-blocking ribs 520 is connected to the inner bottom of the wastewater box 5. All the slag-blocking ribs 520 are spaced apart to form a baffle structure to cover the wastewater outlet.

[0091] Specifically, seven slag-blocking ribs 520 are provided. Four of these ribs are parallel to the side wall where the wastewater outlet is located, with two ribs forming a group. These two groups are located on either side of the wastewater outlet in the horizontal direction. The remaining three ribs are perpendicular to the side wall where the wastewater outlet is located, and these three ribs are spaced apart from the side wall where the wastewater outlet is located. The slag-blocking mechanism 52 is not limited to a structure with multiple slag-blocking ribs 520; it can also be directly set as a hemispherical slag-blocking net, which is fixedly or detachably installed in the wastewater box 5 and covers the wastewater outlet.

[0092] In this embodiment, a press valve core connector 53 is installed through the wastewater outlet. A docking bracket 54 is provided on the housing 1, and a press valve seat 55 is provided on the docking bracket 54. One end of the press valve core connector 53 protruding from the outside of the wastewater box 5 can be inserted into the press valve seat 55 to achieve a sealed connection. When the press valve core connector 53 is separated from the press valve seat 55, the press valve core connector 53 is in a blocked state. When the press valve core connector 53 is inserted into the press valve seat 55, the press valve core connector 53 is in an open state, allowing water in the wastewater box 5 to be discharged from the wastewater box 5. The end of the press valve seat 55 away from the press valve core connector 53 is connected to the second water guide pipe 25. By setting the press valve core connector 53 and the press valve seat 55, it is possible to prevent water leakage at the wastewater outlet when the wastewater box 5 is disassembled, which facilitates the cleaning and rinsing of impurities in the wastewater box 5, and enables quick installation and rapid connection, reducing the difficulty of operation.
