Description

Technical Field

[0001] The invention belongs to the field of household appliances, and in particular relates to a water inlet pipe of a washing device and the washing device. Background Art

[0002] Laundry equipment refers to equipment used to wash clothes, such as washing machines.

[0003] The water inlet pipe of a washing machine refers to the pipe used to supply water into the barrel of the washing machine.

[0004] The barrel body of some washing equipment that holds washing water is sealed. When adding water into the barrel body, the air in the barrel body cannot be discharged, and the water flow is affected by the air pressure in the barrel body and cannot continue to enter the barrel body, causing the water adding failure.

[0005] To solve this problem, this type of washing equipment currently has a separate air vent connecting the inside and outside of the barrel. When water is taken in, the water in the barrel is discharged through the air vent to balance the air pressure inside and outside the barrel, so that water can continue to flow into the barrel and maintain stable water inflow.

[0006] However, this method requires an additional vent pipe, and the barrel body also needs to have an additional hole that penetrates the barrel body, which increases the production cost.

[0007] In view of this, the present invention is proposed. Summary of the invention

[0008] The present invention provides a water inlet pipe for washing equipment and washing equipment, the purpose of which is to balance the air pressure inside and outside the barrel when water is inlet without separately setting a vent pipe, thereby ensuring smooth water inlet.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0010] A water inlet pipe of a washing device has a water inlet channel embedded therein for water intake, and a ventilating channel is formed between the water inlet channel and the pipe wall of the water inlet pipe for balancing the air pressure at both ends of the water inlet pipe.

[0011] Furthermore, the water inlet pipe includes a water inlet end, the water inlet channel is embedded in the water inlet end, one end of the air inlet channel is connected to the inside of the water inlet pipe, and the other end is connected to the external gas of the water inlet pipe for balancing the air pressure inside and outside the water inlet pipe.

[0012] Furthermore, the peripheral side wall of the water inlet channel is concentrically arranged with the peripheral side wall of the water inlet pipe, and the peripheral side wall of the water inlet channel and the peripheral side wall of the water inlet pipe form the air permeable channel.

[0013] Furthermore, the outer peripheral side wall of the water inlet channel has an extension wall which radially extends toward the inner peripheral side wall of the water inlet pipe and is connected to the inner peripheral side wall of the water inlet pipe, and the extension wall is provided with a vent hole which connects the inside and outside of the water inlet pipe.

[0014] Furthermore, the water inlet channel comprises a water outlet for discharging water into the water inlet pipe, and the air permeable opening on the extension wall is spaced apart from the water outlet end surface of the water inlet channel outlet.

[0015] Furthermore, the extension wall is integrally formed with the peripheral side wall of the water inlet pipe and the peripheral side wall of the water inlet channel.

[0016] Furthermore, the water inlet end of the water inlet pipe is connected with a bending structure on a side away from the water inlet pipe opening, and the air vent is arranged between the bending structure and the water inlet pipe opening.

[0017] Preferably, the vent is located inside the bending structure.

[0018] Furthermore, the water inlet pipe comprises a water inlet end and a water outlet end, and the water inlet channel extends from the water inlet end to the water outlet end to isolate the water flow and air flow in the water inlet pipe.

[0019] A washing device comprises any of the above-mentioned water inlet pipes, a barrel body and a water outlet of a distributor box, wherein the water inlet end of the water inlet pipe is connected to the water outlet of the distributor box, and the water outlet end of the water inlet pipe is connected to the barrel body.

[0020] Furthermore, the central axis of the water inlet end of the water inlet pipe is arranged in the vertical direction and the water inlet end pipe opening is upwardly connected to the water outlet of the distributor box.

[0021] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0022] 1. The water inlet pipe is embedded with a water inlet channel, so that the water inlet pipe can have both water inlet and ventilation functions. When the water inlet pipe is used to inlet water to a washing machine with a closed barrel, water flows in from the water inlet end of the water inlet pipe, flows into the barrel through the water inlet pipe, and the air in the barrel enters the water inlet pipe and is discharged through the ventilation channel. Without separately setting up a ventilation pipe, only one water inlet pipe is used to maintain the balance of air pressure inside and outside the closed barrel of the washing machine, ensuring smooth water inlet, simplifying the structure and reducing costs.

[0023] 2. The water inlet channel is only arranged in the water inlet end, which can simplify the structure and reduce the length of the water inlet channel on the basis of balancing the air pressure, thereby reducing the cost and production difficulty.

[0024] 3. The extended wall connecting the side wall of the water inlet pipe and the side wall of the water inlet channel plays a role in fixing the water inlet channel, preventing the water inlet channel from shaking and squeezing the air permeable channel when water is flowing in, thereby ensuring the stability of the air permeable channel.

[0025] 4. The air vent on the extension wall is spaced apart from the water outlet of the water inlet channel, which can effectively prevent water flowing out of the water outlet of the water inlet channel from flowing along the surface of the water inlet channel to the extension wall and then leaking from the air vent. Even if a small amount of water flows laterally along the surface of the water outlet of the water inlet channel, it cannot flow upward along the outer wall of the water outlet of the water inlet channel to the extension wall, and can only drip downward into the water inlet pipe, further avoiding the risk of water leakage.

[0026] 5. The water inlet end, the water inlet channel and the extension wall are arranged in one piece, which can effectively improve the strength of the water inlet channel and the extension wall, avoid the water inlet channel from falling off when installing the water inlet pipe, and improve the reliability of the water inlet pipe.

[0027] 6. The vent is arranged on the inner side of the bent structure of the water inlet pipe, which can reduce the probability of water accumulating in the water inlet pipe and overflowing from the vent when the water inlet end of the water inlet pipe is installed horizontally.

[0028] 7. The water inlet end of the water inlet pipe is connected to the water outlet of the distributor box, and the water outlet end of the water inlet pipe is connected to the barrel of the washing device. The water in the distributor box enters the barrel of the washing device through the water inlet pipe, and the water in the barrel is pressed out and enters the water inlet pipe from the water outlet end of the water inlet pipe, and then is discharged through the air permeable channel of the water inlet pipe. It is realized that only one water inlet pipe is used to complete water inlet and air permeability at the same time, and there is no need to set up an additional air permeable pipe, which has a simple structure and lower cost.

[0029] 8. The water inlet end of the water inlet pipe is arranged in the vertical direction, so that when the water inlet channel is taking in water, the water flows from the water outlet of the water inlet channel into the water inlet pipe from top to bottom under the action of gravity, thereby preventing the water from flowing back from the water inlet pipe to the secondary air vent located on the extension wall, thereby avoiding the risk of water leakage.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0039] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The present invention proposes a Figures 1 to 4 The washing equipment water inlet pipe and the washing equipment shown, the washing equipment refers to equipment used for washing clothes, such as a washing machine, a dishwasher, etc. In the present invention, it mainly refers to equipment with a sealed barrel body, such as a drum washing machine.

[0042] The washing device comprises a barrel body for containing washing water and a barrel cover that can open and close the barrel body. When the barrel cover is closed, the inside of the barrel body is in a sealed state, and the control inside the barrel body cannot be exchanged and circulated outside the barrel body. The barrel body is provided with an opening for water to enter the barrel body.

[0043] The water inlet pipe of a washing machine refers to the pipe used to supply water into the barrel of the washing machine.

[0044] The present invention proposes a Figures 1 to 4 The water inlet pipe of the washing equipment shown is used to guide the incoming water flow into the interior of the barrel.

[0045] The water inlet pipe comprises a water inlet end 1 and a water outlet end 5. Water flows into the water inlet pipe from the water inlet end 1 and flows out of the water outlet pipe from the water outlet end 5. After flowing out from the water outlet end 5, the water flows into the barrel body.

[0046] A water inlet channel 2 for water intake is embedded in the water inlet pipe, and an air permeable channel is formed between the water inlet channel 2 and the pipe wall of the water inlet pipe to balance the air pressure at both ends of the water inlet pipe.

[0047] In the present invention, a water inlet channel 2 is embedded in the water inlet pipe, so that the water inlet pipe can have two functions of water inlet and ventilation. When the water inlet pipe is used for water inlet of a washing device with a closed barrel, water flows in from the water inlet end 1 of the water inlet pipe, flows into the barrel through the water inlet pipe, and the air in the barrel enters the water inlet pipe and is discharged through the ventilation channel. In the case of not separately setting a ventilation pipe, only one water inlet pipe is used to maintain the balance of air pressure inside and outside the closed barrel of the washing device, thereby ensuring smooth water inlet, simplifying the structure and reducing costs.

[0048] As an embodiment of the present invention, a water inlet channel 2 is embedded inside the water inlet end 1 of the water inlet pipe, and a ventilated channel is formed between the water inlet channel 2 and the water inlet pipe to connect the inside and outside of the water inlet pipe and balance the air pressure inside and outside the water inlet pipe.

[0049] Furthermore, the water inlet channel 2 is only provided at the water inlet end 1, and the other parts of the water inlet pipe do not have the water inlet channel 2. After the water flows into the water inlet pipe through the water inlet channel 2, it flows in the air inlet pipe together with the air flow.

[0050] In the present invention, water flows into the water inlet pipe from the water inlet channel 2, flows from the water inlet end 1 to the water outlet end 5, and air flows into the water inlet pipe from the water outlet end 5, flows from the water outlet end 5 to the water inlet end 1, and then leaves the water inlet pipe through the air permeable channel. It is achieved that water is taken in and air is ventilated at the same time through a water inlet pipe with an air permeable channel. And the air permeable channel only needs to be set to a section much smaller than the length of the water inlet pipe, which greatly saves costs compared with a separately set air permeable pipe.

[0051] As an embodiment of the present invention, Figures 1 to 4 As shown, the peripheral side wall of the water inlet channel 2 is concentrically arranged with the peripheral side wall of the water inlet pipe, and the peripheral side wall of the water inlet channel 2 and the peripheral side wall of the water inlet pipe form the air permeable channel. Specifically, the outer peripheral side wall of the water inlet channel 2 and the inner peripheral side wall of the water inlet pipe form the air permeable channel.

[0052] As an implementation of this embodiment, further, the cross-sections of the water inlet pipe and the water inlet channel 2 perpendicular to the axial direction are both circular, and the water inlet pipe and the water inlet channel 2 are concentrically arranged. The air permeable channel is annular.

[0053] As required, the water inlet channel 2 may also be eccentrically arranged in the water inlet pipe, and the cross-sections of the water inlet channel 2 and the water inlet pipe perpendicular to the axial direction may also be arranged in shapes other than a circle.

[0054] In this embodiment, the airflow entering the air inlet pipe from the water outlet end 5 can flow out from the air permeable channel formed by the peripheral side walls of the water inlet channel 2 and the peripheral side walls of the water inlet pipe to balance the air pressure inside and outside the air inlet pipe.

[0055] As an implementation method of this embodiment, Figures 1 to 4 As shown, the outer peripheral side wall of the water inlet channel 2 has an extension wall 4 that radially extends toward the inner peripheral side wall of the water inlet pipe and is connected to the inner peripheral side wall of the water inlet pipe. The extension wall 4 is provided with a vent 3 that connects the inside and outside of the water inlet pipe.

[0056] Furthermore, the extension wall 4 can be an annular sheet structure connecting the inner peripheral side wall of the water inlet pipe and the outer peripheral side wall of the water inlet channel 2, and a through hole is opened on the annular sheet structure, and the through hole connects the inside and outside of the water inlet pipe to form a vent 3.

[0057] Furthermore, the extension wall 4 can be a partial annular sheet structure that partially connects the inner side wall of the water inlet pipe and the outer side wall of the water inlet channel 2, and the portion between the inner side wall of the water inlet pipe and the outer side wall of the water inlet channel 2 that is not connected by the extension wall 4 forms a vent 3 that connects the inside and outside of the water inlet pipe.

[0058] In this embodiment, the airflow in the water inlet pipe flows out of the water inlet pipe through the air vent 3, balancing the air pressure inside and outside the water inlet pipe when water is entering the water inlet pipe, thereby preventing the water flow from being affected by excessive air pressure in the water inlet pipe when water is entering.

[0059] As another implementation of this embodiment, the extension wall 4 is connected to a side of the water inlet end 1 of the water inlet pipe away from the pipe opening.

[0060] Furthermore, the vent 3 is arranged at a position far away from the pipe opening of the water inlet pipe.

[0061] Preferably, the water inlet channel 2 further includes a water inlet, and the extension wall 4 is located between the water outlet 21 of the water inlet channel and the water inlet.

[0062] In this embodiment, the extension wall 4 is away from the pipe mouth of the water inlet pipe. Even if the water flowing into the washing water inlet pipe from the water inlet channel outlet 21 leaks out from the air vent 3, because the air vent 3 is still one end distance away from the pipe mouth, the water will not leak directly from the pipe, thereby reducing the possibility of leakage.

[0063] As another implementation of this embodiment, Figure 3 As shown, the water inlet channel 2 includes a water inlet channel outlet 21 , and the extension wall 4 is spaced apart from the water inlet channel outlet 21 .

[0064] Furthermore, the air vent 3 is spaced apart from the water outlet 21 of the water inlet channel.

[0065] When water flows out of the water outlet 21 of the water inlet channel, part of the water may flow along the surface of the water inlet channel 2 to the extension wall 4, and then flow to the air vent 3 through the extension wall 4. Under the action of the airflow flowing from the inside of the air inlet pipe to the outside of the air inlet pipe, this part of the water will flow out from the air vent 3, causing water leakage.

[0066] In this embodiment, the extension wall 4 is spaced apart from the water outlet 21 of the water inlet channel, that is, the air vent 3 is spaced apart from the water outlet 21 of the water inlet channel. Even if a small amount of water flows along the surface of the water inlet channel 2, it can no longer flow back along the outer wall of the water inlet channel 2 to the extension wall 4, thereby avoiding water leakage from the air vent 3 of the water inlet pipe.

[0067] As another implementation method of this embodiment, Figures 1 to 4 As shown, the water inlet end 1, the water inlet channel 2, and the extension wall 4 are fixedly connected;

[0068] Preferably, the water inlet end 1, the water inlet channel 2 and the extension wall 4 are integrally arranged.

[0069] The extension wall 4 plays a role in fixing the water inlet channel 2 located in the water inlet pipe, so that the water inlet channel 2 can be stably in the water inlet pipe, and prevents the water inlet channel 2 from moving and affecting the ventilation channel or even leaking.

[0070] As another embodiment of the present invention, Figures 1 to 4 As shown, the water inlet end 1 of the water inlet pipe is connected with a bending structure 7 on the side away from the pipe opening of the water inlet end 1 .

[0071] The bending structure 7 can play a certain blocking role when the water outlet end 5 of the water inlet pipe flows into the water inlet pipe, thereby preventing the foam from leaking from the air vent 3 after entering the water inlet pipe and causing pollution to the washing equipment.

[0072] As another embodiment of the present invention, Figures 1 to 4 As shown, a side of the water inlet end 1 away from the pipe opening is connected with a bending structure 7, and the air vent 3 is arranged between the bending structure 7 and the pipe opening of the water inlet end 1.

[0073] Furthermore, the vent 3 is located inside the bending structure 7 .

[0074] When the washing machine is washing, a large amount of foam may flow into the water inlet pipe from the barrel connected to the water inlet pipe, so a bending structure 7 is provided on the water inlet pipe to prevent the foam from flowing into the water inlet pipe and leaking out of the washing machine from the water inlet pipe to cause pollution.

[0075] After the water flows out of the water outlet 21 of the water inlet channel, it will flow to the side wall of the water inlet pipe outside the bending structure 7, and flow along the side wall of the water inlet pipe outside the bending structure 7, causing certain obstruction to the position of the extension wall 4 corresponding to the axial direction of the water inlet pipe of the bending structure 7, affecting the smoothness of the airflow in this direction.

[0076] Furthermore, if the water inlet end 1 of the water inlet pipe is arranged horizontally, water will accumulate more easily on the outside of the bending structure 7 than on the inside of the bending structure 7, causing water to flow back toward the extension wall 4. If the air vent 3 is arranged on the outside of the bending structure 7, water leakage will occur due to the backflow of water.

[0077] In this embodiment, the vent 3 is arranged inside the bending structure 7, which can effectively avoid the influence of water flow on air flow and ensure smooth air flow. When the water inlet end 1 is arranged horizontally, water leakage of the vent 3 can be avoided to the greatest extent.

[0078] As an embodiment of the present invention, the water inlet pipe includes a water inlet end 1 and a water outlet end 5, and the water inlet channel 2 extends from the water inlet end 1 to the water outlet end 5 to isolate the water flow and air flow in the water inlet pipe.

[0079] In this embodiment, the water flow and air flow in the water inlet pipe are isolated by the water inlet channel 2 that runs through the water inlet pipe, so as to avoid interference between the water flow and the air flow when they flow in opposite directions and thus generate noise, thereby improving the user experience.

[0080] As another embodiment of the present invention, Figures 1 to 4 As shown, the water inlet pipe includes a vertical portion extending from bottom to top, and the vertical portion refers to a vertically arranged portion. When the water inlet pipe is installed and used, the vertical portion is installed in a vertical direction.

[0081] Furthermore, the air vent 3 is located in the vertical portion, water flows into the water inlet pipe from top to bottom, and air flows out through the air vent 3 from bottom to top.

[0082] Preferably, the vertical portion includes a water inlet channel 2;

[0083] Preferably, the vertical portion includes a water inlet end 1 .

[0084] In this embodiment, the vertical portion is vertically arranged from bottom to top. When water is taken in, the water flows from the water outlet 21 of the water inlet channel and flows from top to bottom under the action of gravity. The water flow entering the water inlet pipe cannot flow from bottom to top to the extension wall 4 and the air vent 3, and there is no risk of water leakage.

[0085] As another embodiment of the present invention, Figures 1 to 4 As shown, the water inlet pipe also includes a positioning mark 11 arranged at the water inlet end. Specifically, the water inlet end positioning mark 11 is a protrusion arranged at the pipe mouth.

[0086] Alternatively, the water inlet end positioning mark 11 is a notch arranged at the pipe opening of the water inlet end 1 .

[0087] In this embodiment, a water inlet end positioning mark 11 is provided at the water inlet end 1, so that the installation position can be distinguished when installing the water inlet pipe, thereby avoiding misalignment of the installation to block the air holes and affect the air flow.

[0088] Furthermore, the water outlet end 5 of the water inlet pipe is provided with a water outlet positioning mark 51 , and the water outlet positioning mark 51 of the water outlet end 5 is a notch provided at the pipe opening of the water outlet end 5 .

[0089] As an implementation mode of this embodiment, convex patterns are arranged on the pipe wall of the water inlet end 1 of the water inlet pipe along the circumferential direction, and the convex patterns can be snap-connected or screw-connected with the washing equipment.

[0090] Furthermore, the water inlet channel 2 can be plugged, snap-connected or screwed to the water supply structure on the washing device.

[0091] As another embodiment of the present invention, the water inlet pipe includes a mounting portion, and the mounting portion is located on the outer side wall of the water inlet pipe and is used to be fixed to the washing device to prevent the water inlet pipe from vibrating or falling off.

[0092] Furthermore, the mounting portion is fixed to the barrel body of the washing device by snap-fitting.

[0093] As an implementation mode of this embodiment, an elastic portion 6 is provided between the water inlet end 1 and the mounting portion, and the elastic portion 6 can elastically change along the axial and radial directions of the water inlet pipe.

[0094] Specifically, the elastic part 6 is a bellows.

[0095] In this embodiment, a bellows is provided between the water inlet end 1 and the mounting portion, which can play a buffering role when the mounting portion vibrates or shakes with the barrel body, thereby preventing the vibration of the mounting portion from affecting the stability of the water inlet end 1 on the washing device.

[0096] As another embodiment of the present invention, the water inlet pipe includes three parts: a water inlet end 1, a water outlet end 5, and a middle section. A bending structure 7 is provided between the water inlet end 1 and the middle section, and between the middle section and the water outlet end 5.

[0097] During the washing process, the bending structure 7 has a blocking effect on the foam entering from the water outlet 5, preventing the foam from overflowing from the washing device.

[0098] Furthermore, the elastic portion 6 is arranged between the water inlet end 1 and the middle section, and the connecting portion is arranged on the outer peripheral side wall of the middle section. During washing, the connecting portion fixes the middle section on the barrel body. When the barrel body vibrates, the middle section vibrates along with the barrel body, and the elastic portion 6 extends and contracts along with the movement of the middle section to avoid affecting the water inlet end 1.

[0099] Furthermore, the circumferential cross-sectional area of ​​the middle section and the water outlet end 5 of the water inlet pipe is larger than the circumferential cross-sectional area of ​​the water inlet channel 2.

[0100] Preferably, the circumferential cross-sectional area of ​​the middle section of the water inlet pipe and the water outlet end 5 is the same as the circumferential cross-sectional area of ​​the water inlet end 1 .

[0101] When water enters the water inlet pipe, the water in the water inlet channel 2 flows into the water inlet pipe, and the air in the air permeable channel flows out of the water inlet pipe. If the water inlet flow is large, the water flowing out of the water inlet channel outlet 21 will occupy a portion of the water inlet pipe that is the same as the circumferential cross-sectional area of ​​the water inlet channel 2. If the middle section and the water outlet end 5 are too thin, there will be no space to control the flow when water enters, resulting in air permeability.

[0102] As another embodiment of the present invention, the water inlet pipe includes a water inlet channel 2 and a ventilation channel, and the water inlet channel 2 and the ventilation channel are arranged side by side in the water inlet pipe, and the water inlet channel 2 and the ventilation channel are of the same length as the water inlet pipe.

[0103] When water is taken in, water flows into the water inlet pipe from the water inlet channel 2, and air flows out of the water inlet pipe from the ventilation channel. The water flow and air flow flow from independent and separated channels respectively, avoiding mutual interference and the risk of water leakage from the ventilation channel.

[0104] The present invention also proposes a washing device, which refers to a device used to wash clothes, such as a washing machine, a dishwasher, etc. The washing device includes a barrel for accommodating clothes. The barrel of some washing devices is closed when in use and cannot exchange air with the outside, such as a drum washing machine.

[0105] The washing device comprises the water inlet pipe of the present invention and comprises a barrel body for containing washing water and a barrel cover for opening and closing the barrel body. Before each washing and water addition, the barrel cover is closed to isolate the inside and outside of the barrel body and prevent water leakage.

[0106] The washing device comprises a detergent box for storing and dispensing detergent, and the detergent box comprises a dispenser box for dispensing detergent. The detergent is mixed with water from a tap water pipeline in the dispenser box and flows toward the barrel.

[0107] The barrel body is provided with an opening, the water outlet end 5 of the water inlet pipe is connected to the opening on the barrel body, the water inlet end 1 of the water inlet pipe is connected to the dispenser box of the washing device, and the water mixed with the detergent in the dispenser box flows into the water inlet pipe.

[0108] Specifically, the water inlet end 1 includes a water inlet channel 2 and a ventilation channel, and the water outlet of the distributor box is only connected to the water inlet channel 2.

[0109] Furthermore, the air passage of the water inlet pipe may be connected to the outside of the washing device through a specially provided external air passage, or may be directly open.

[0110] Furthermore, if the ventilation channel is open, a filter needs to be provided at the opening of the ventilation channel to prevent dust and other dirt from entering through the ventilation opening 3 .

[0111] Furthermore, the water inlet end 1 of the water inlet pipe can be connected to the water outlet of the distributor box in the form of snap connection, plug connection, screw connection, etc., and the water outlet of the distributor box can abut against the extension wall 4 of the water inlet pipe.

[0112] Furthermore, a ventilation channel is reserved at the position of the water outlet of the distributor box corresponding to the ventilation port 3 of the water inlet pipe. During assembly, the installation angle of the water inlet pipe is determined according to the water inlet end positioning mark 11 on the water inlet pipe so that the ventilation port 3 of the water inlet pipe corresponds to the water outlet of the distributor box to avoid blocking the ventilation channel.

[0113] As an embodiment of the present invention, the central axis of the water inlet end 1 of the water inlet pipe is arranged in the vertical direction and the pipe opening of the water inlet end 1 faces upward and is connected to the water outlet of the distributor box.

[0114] Furthermore, the water outlet of the distributor box is extended from top to bottom, and the water inlet end 1 of the water inlet pipe is connected with the water outlet of the distributor box with the pipe opening facing upward. After connection, the water inlet end 1 of the water inlet pipe maintains a vertical state with the pipe opening facing upward.

[0115] Furthermore, the water inlet channel 2 of the water inlet pipe is plugged, screwed or snapped into the water outlet of the distributor box from bottom to top.

[0116] In this embodiment, the water inlet end 1 is vertically arranged from bottom to top. When water is taken in, the water flows from the water outlet 21 of the water inlet channel and flows from top to bottom under the action of gravity. The water flow entering the water inlet pipe cannot flow from bottom to top to the extension wall 4 and the air vent 3, and there is no risk of water leakage.

[0117] As an embodiment of the present invention, the vertical portion of the water inlet pipe is installed in a vertical direction and is connected to the water outlet of the distributor box.

[0118] Furthermore, the water outlet of the distributor box is extended from top to bottom, and the vertical portion of the water inlet pipe is connected with the water outlet of the distributor box with the pipe opening facing upward. After the connection, the vertical portion of the water inlet pipe maintains a vertical posture with the pipe opening facing upward.
