A shower device for a washing machine and a washing machine

Abstract

The application discloses a shower device for a washing machine and the washing machine, and the shower device comprises a shower box, a water inlet pipe for supplying water to the shower box, and an air inlet pipe arranged in the water inlet pipe and used for allowing external air to enter the water inlet pipe during water inlet of the water inlet pipe and after water inlet is stopped. A gas outlet is arranged at the front end of the air inlet pipe. By arranging the air inlet pipe, negative pressure is generated at the gas outlet of the air inlet pipe during water inlet of the water inlet pipe, so that external air is sucked into the air inlet pipe. After the gas flows out of the gas outlet, the gas is mixed with water in the water inlet pipe to form liquid mixed with bubbles. When the bubbles burst, transient high temperature and impact force are generated on a micro level, which is beneficial to dissolution of the detergent. After water inlet is stopped, external air enters the air inlet pipe, so that negative pressure is not generated when the liquid flows out of the shower box, and residual liquid in the shower box flows out quickly under the action of gravity.

Description

Technical Field

[0001] This invention belongs to the field of washing machine technology, specifically relating to a shower head device for a washing machine and a washing machine having the shower head device. Background Technology

[0002] As people's living standards continue to improve, washing machines have gradually become one of the essential home appliances in people's homes, and most people regard washing machines as the main tool for washing clothes.

[0003] With continuous innovation and improvement in washing machine technology, most washing machines now come equipped with a water inlet box assembly for adding laundry detergent or fabric softener. This assembly typically consists of a water inlet box, a spray box, and a material dispenser. The material dispenser includes at least one of the following: a laundry detergent dispenser, a fabric softener dispenser, or a detergent dispenser. The main function of the spray box in the water inlet box assembly is to evenly mix the laundry detergent or fabric softener and add it to the inner drum of the washing machine for washing, while also preventing laundry detergent from sticking to the side walls of the material dispenser.

[0004] The existing shower box has the following shortcomings in use: when the water inlet valve is closed, the inside of the shower box cannot directly communicate with the air, and the water supply pressure disappears. Although the water in the shower box is affected by gravity, it needs to overcome the surface tension of the water and the negative pressure generated when the water flows out. Therefore, the residual water in the shower box will not flow out quickly, but will drip slowly, and there will always be a certain amount of water remaining in the shower box. This leads to the following problems: 1. After the washing machine is finished, the dripping water still produces noise, making users feel that the washing machine is malfunctioning, resulting in user complaints or after-sales costs; 2. Long-term water retention will lead to scale buildup, reducing the orifice diameter or even clogging the spray nozzles, requiring manual cleaning; 3. The residual water in the shower box for too long will lead to the growth of bacteria.

[0005] Meanwhile, the water in the shower head box is sprayed into the material box to dissolve detergent (including laundry powder, detergent, fabric softener, etc.). Insufficient dissolution often occurs, causing undissolved laundry powder to be flushed into the washing drum, which is not conducive to the effective cleaning of detergent; or detergent or fabric softener may stick to the wall of the material box, so that when water enters during the rinsing stage, it is flushed into the washing drum, which is not conducive to rinsing cleanly.

[0006] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0007] To address the aforementioned problems in the prior art, this invention proposes a shower head device for a washing machine. By incorporating an air inlet pipe, it enables outside air to enter and form bubbles during water intake, which facilitates detergent dissolution. Furthermore, after water intake stops, the inlet pipe is connected to the outside environment, allowing for rapid drainage within the shower head box.

[0008] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0009] A shower head device for a washing machine, comprising:

[0010] The shower box has multiple spray holes on its bottom surface;

[0011] The water inlet pipe is used to supply water to the shower box;

[0012] An air inlet pipe is provided inside the water inlet pipe and is used to allow outside air to enter the water inlet pipe during the water intake process and after the water intake stops.

[0013] The air intake pipe has an air outlet at its front end.

[0014] Furthermore, the air inlet pipe has an air outlet that faces the direction of water flow in the water inlet pipe.

[0015] Furthermore, the air inlet pipe has an air outlet section at one end, and the air outlet section is arranged parallel to the axis of the water inlet pipe.

[0016] Furthermore, the air outlet section extends along the water flow direction of the water inlet pipe.

[0017] Furthermore, the water inlet pipe is a round pipe.

[0018] Furthermore, the air outlet section is a circular pipe, and the axis of the air outlet section coincides with the axis of the water inlet pipe.

[0019] Furthermore, the intake pipe also has an intake section that communicates with the outside, and an arc-shaped connecting section that connects the intake section and the exhaust section.

[0020] Furthermore, the air intake section is arranged radially along the water inlet pipe.

[0021] Furthermore, the angle between the air intake section and the air outlet section is greater than or equal to 90°.

[0022] Furthermore, the angle between the air intake section and the air outlet section is 130° to 150°.

[0023] Furthermore, the ratio of the inner diameter of the water inlet pipe to the inner diameter of the air inlet pipe is 10 to 30.

[0024] Furthermore, the ratio of the length of the intake section to the length of the exhaust section is 2 to 10.

[0025] Furthermore, an air inlet hole is provided on the wall of the water inlet pipe, and the air inlet pipe is sealed and connected to the air inlet hole.

[0026] Furthermore, the air inlet is located on the upper side of the water inlet pipe wall.

[0027] Furthermore, it also includes an inlet valve for controlling the water inlet pipe to enter and stop the water inlet, the inlet valve being connected and fixed to the water inlet pipe.

[0028] Furthermore, it also includes at least a separator at the outlet for separating the flowing gas into microbubbles.

[0029] Furthermore, the gas outlet section is provided with an axially extending partition, which divides the internal space of the gas outlet section into multiple gas channels.

[0030] Furthermore, the partition has a plurality of radially arranged partitions.

[0031] Furthermore, the partition is a mesh cover structure fastened to the air outlet.

[0032] Based on the above-mentioned shower head device for a washing machine, the present invention also provides a washing machine having the shower head structure. By setting an air inlet pipe, external air can be introduced to form bubbles during the water inlet process, which is beneficial to the dissolution of detergent; and after the water inlet stops, the water inlet pipe is connected to the outside to achieve rapid drainage in the shower head box.

[0033] A washing machine having the above-described shower head structure.

[0034] Compared with existing technologies, the advantages and positive effects of this invention are as follows: By setting up an air inlet pipe, during the water inlet process, water flows into the shower box at a certain flow rate, and the air outlet section extends along the water flow direction of the water inlet pipe. A negative pressure is generated at the air outlet of the air inlet pipe, causing external air to be drawn in through the air inlet pipe. After the gas flows out from the air outlet, it mixes with the water in the water inlet pipe, forming a liquid mixed with bubbles. When the bubbles burst, they generate instantaneous high temperature and impact force, which is beneficial for the dissolution of detergent. When the water inlet stops, the water pressure in the shower box and the water inlet pipe decreases rapidly, and outside air enters through the air inlet pipe, so that the liquid no longer generates negative pressure when flowing out of the spray nozzles. Under the action of gravity, the residual liquid in the shower box flows out quickly.

[0035] Other features and advantages of the present invention will become clearer after reading the detailed embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0047] Example 1

[0048] See Figures 1-2This is the first embodiment of a shower head device for a washing machine proposed in this invention. The shower head device for a washing machine includes: a shower head box 10, a water inlet pipe 20, and an air inlet pipe 30. A plurality of spray holes 11 are provided on the bottom surface of the shower head box 10. The water inlet pipe 20 is connected to the shower head box 10 and is used to supply water to the shower head box 10. The air inlet pipe 30 is disposed inside the water inlet pipe 10. The opening of the air outlet 34 of the air inlet pipe 30 faces the direction of water flow in the water inlet pipe 20, that is, the direction of gas flow from the air outlet 34 is consistent with the direction of water flow in the water inlet pipe 20. Before defining the direction of water flow in the water inlet pipe 20, the air outlet 34 is opened at the front end of the air inlet pipe 30, and the air outlet 34 is formed by surrounding the front end of the air inlet pipe 30. The air inlet pipe 30 is used to allow outside air to enter the water inlet pipe 20 during the water intake process, mixing with the water in the water inlet pipe 20 to form a liquid mixed with bubbles. The air inlet pipe 30 also allows outside air to enter the water inlet pipe 20 after the water intake stops, thus connecting the water inlet pipe 20 with the outside air. By setting up the air inlet pipe 30, during the water intake process, because the opening of the air outlet 34 of the air inlet pipe 30 faces the direction of water flow in the water inlet pipe 20, a certain flow rate of water flows into the shower box 10, creating a negative pressure at the air outlet 34 of the air inlet pipe 30, causing outside air to be drawn in through the air inlet pipe 30. After the gas flows out from the air outlet 34, it mixes with the water in the water inlet pipe 20 to form a liquid mixed with bubbles. When the bubbles burst, they generate instantaneous high temperature and impact force, which is beneficial for the dissolution of detergent. When the water supply stops, the water pressure in the shower box 10 and the water inlet pipe 20 decreases rapidly. The water in the nozzle 11 is restricted from flowing out due to surface tension and negative pressure. Just as the water in the nozzle 11 is about to flow out, outside air enters the water inlet pipe 20 from the air inlet pipe 30. Therefore, the negative pressure that prevents the water in the nozzle 11 from flowing out disappears, and the water can drip down quickly, avoiding residual liquid in the shower box.

[0049] See Figure 2 As shown, the water inlet pipe 30 has an air outlet section 31 with an air outlet 34 at its end. The air outlet section 31 extends along the water flow direction of the water inlet pipe 20, that is, the air outlet section 31 is parallel to the axis of the water inlet pipe 20. This ensures that the flow direction of the gas flowing out of the air outlet 34 and into the water inlet pipe 20 is completely consistent with the flow direction of the water in the water inlet pipe 20. This is beneficial for the formation of a negative pressure zone at the air outlet 34, which is beneficial for the formation of uniform bubbles. It also helps to reduce the impact between the airflow and the water flow, thus reducing energy consumption. At the same time, it avoids insufficient negative pressure when the water flow speed in the water inlet pipe 20 is slow, thus preventing water from exiting the air inlet pipe 30.

[0050] The water inlet pipe 20 is a circular pipe, and the air outlet section 31 is a circular pipe. Preferably, the axis of the air outlet section 31 is arranged to coincide with the axis of the water inlet pipe 21, so that the gas entering the water inlet pipe 20 from the air outlet 34 can be evenly distributed radially in the direction of water flow.

[0051] The air intake pipe 30 also has an air intake section 32 that communicates with the outside, and an arc-shaped connecting section 33 that connects the air intake section 32 and the air outlet section 31. In this embodiment, the air intake section 32 is arranged radially along the water inlet pipe 20, and the air outlet section 31 is arranged axially along the water inlet pipe 20, that is, the air intake section 32 and the air outlet section 31 are arranged perpendicularly.

[0052] In other embodiments, the air intake section 32 may be set at an angle, that is, the angle between the air intake section 32 and the air outlet section 32 is greater than 90°. Preferably, the angle between the air intake section 32 and the air outlet section 32 is 130° to 150°.

[0053] The inner diameter of the water inlet pipe 20 is much larger than the inner diameter of the air inlet pipe 30. Preferably, the ratio of the inner diameter of the water inlet pipe 20 to the inner diameter of the air inlet pipe 30 is 8 to 25; more preferably, the ratio is 10 to 15. The ratio of the length of the air outlet section 31 to the length of the air inlet section 32 is 2 to 10, preferably 6.

[0054] An air inlet hole 22 is provided on the wall of the water inlet pipe 20, and an air inlet pipe 30 is sealed and connected to the air inlet hole 22. Preferably, the air inlet hole 22 is located on the upper side of the water inlet pipe 20 to prevent water from flowing out of the air inlet hole 22 when the water supply stops. The shower device also includes a water inlet valve for controlling the water supply and stopping of the water supply in the water inlet pipe 20, and the water inlet valve is connected and fixed to the water inlet pipe 20.

[0055] Example 2

[0056] See Figures 3-4 This is the second embodiment of a shower head device for a washing machine proposed in this invention. The main difference between this embodiment and the first embodiment is that it has a partition, but the rest can adopt the same structure as the first embodiment.

[0057] A shower head device for a washing machine includes: a shower head box 10, a water inlet pipe 20, and an air inlet pipe 30. Multiple spray holes 11 are provided on the bottom surface of the shower head box 10. The water inlet pipe 20 is connected to the shower head box 10 and is used to supply water to the shower head box 10. The air inlet pipe 30 is located inside the water inlet pipe 20. The opening of the air outlet 34 of the air inlet pipe 30 faces the direction of water flow in the water inlet pipe 20, meaning that the direction of air flow from the air outlet 34 is consistent with the direction of water flow in the water inlet pipe 20. Before defining the direction of water flow in the water inlet pipe 20, the air outlet 34 is located at the front end of the air inlet pipe 30, and the air outlet 34 is formed by surrounding the front end of the air inlet pipe 30. The air inlet pipe 30 is used to allow outside air to enter the water inlet pipe 20 during the water intake process and mix with the water in the water inlet pipe 20 to form a liquid mixed with bubbles. The air inlet pipe 30 also allows outside air to enter the water inlet pipe 20 after the water intake stops, thus connecting the water inlet pipe 20 with the outside air. By setting up the air inlet pipe 30, during the water intake process, because the opening of the air outlet 34 of the air inlet pipe 30 faces the direction of water flow in the water inlet pipe 20, a certain flow rate of water flows into the shower box 10, creating a negative pressure at the air outlet 34 of the air inlet pipe 30, causing outside air to be drawn in through the air inlet pipe 30. After the gas flows out from the air outlet 34, it mixes with the water in the water inlet pipe 20 to form a liquid mixed with bubbles. When the bubbles burst, they generate instantaneous high temperature and impact force, which is beneficial for the dissolution of detergent. When the water supply stops, the water pressure in the shower box 10 and the water inlet pipe 20 decreases rapidly. The water in the nozzle 11 is restricted from flowing out due to surface tension and negative pressure. Just as the water in the nozzle 11 is about to flow out, outside air enters the water inlet pipe 20 from the air inlet pipe 30. Therefore, the negative pressure that prevents the water in the nozzle 11 from flowing out disappears, and the water can drip down quickly, avoiding residual liquid in the shower box.

[0058] The water inlet pipe 30 has an air outlet section 31 with an air outlet 34 at its end. The air outlet section 31 extends along the water flow direction of the water inlet pipe 20, that is, the air outlet section 31 is parallel to the axis of the water inlet pipe 20. This ensures that the flow direction of the gas flowing out of the air outlet 34 and into the water inlet pipe 20 is completely consistent with the flow direction of the water in the water inlet pipe 20. This is beneficial to the formation of a negative pressure zone at the air outlet 34, which is conducive to the formation of uniform bubbles. It also helps to reduce the impact between the airflow and the water flow, and reduce the impact on the flow rate. At the same time, it avoids insufficient negative pressure when the water flow speed in the water inlet pipe 20 is slow, thus preventing water from exiting the air inlet pipe 30.

[0059] The water inlet pipe 20 is a circular pipe, and the air outlet section 31 is a circular pipe. Preferably, the axis of the air outlet section 31 is arranged to coincide with the axis of the water inlet pipe 21, so that the gas entering the water inlet pipe 20 from the air outlet 34 can be evenly distributed radially in the direction of water flow.

[0060] The air intake pipe 30 also has an air intake section 32 that communicates with the outside, and an arc-shaped connecting section 33 that connects the air intake section 32 and the air outlet section 31. In this embodiment, the air intake section 32 is arranged radially along the water inlet pipe 20, and the air outlet section 31 is arranged axially along the water inlet pipe 20, that is, the air intake section 32 and the air outlet section 31 are arranged perpendicularly.

[0061] The inner diameter of the water inlet pipe 20 is much larger than the inner diameter of the air inlet pipe 30. Preferably, the ratio of the inner diameter of the water inlet pipe 20 to the inner diameter of the air inlet pipe 30 is 8 to 25; more preferably, the ratio is 10 to 15. The ratio of the length of the air outlet section 31 to the length of the air inlet section 32 is 2 to 10, preferably 6.

[0062] An air inlet 22 is provided on the wall of the water inlet pipe 20, and an air inlet pipe 30 is sealed and connected to the air inlet 22. Preferably, the air inlet 22 is located on the upper side of the water inlet pipe 20 to prevent water from flowing out of the air inlet 22. The shower device also includes an inlet valve for controlling the water inlet and stopping the water inlet of the water inlet pipe 20, and the inlet valve is connected and fixed to the water inlet pipe 20.

[0063] In this embodiment, a separator 35 is provided at the air outlet 34. The separator 35 is a mesh structure fastened to the front side of the air outlet 34. The separator 35 is used to separate the flowing gas, which forms microbubbles after mixing with the water in the water inlet pipe 20. This helps to increase the number of bubbles and improve the solubility of detergent.

[0064] Example 3

[0065] See Figures 5-7 This is the third embodiment of a shower head device for a washing machine proposed in this invention. The main difference between this embodiment and the second embodiment is that the structure of the partition is different, but the other parts can adopt the same structure as the second embodiment.

[0066] A shower head device for a washing machine includes: a shower head box 10, a water inlet pipe 20, and an air inlet pipe 30. Multiple spray holes 11 are provided on the bottom surface of the shower head box 10. The water inlet pipe 20 is connected to the shower head box 10 and supplies water to the shower head box 10. The air inlet pipe 30 is located inside the water inlet pipe 10. The opening of the air outlet 34 of the air inlet pipe 30 faces the direction of water flow in the water inlet pipe 20, meaning that the direction of air flow from the air outlet 34 is consistent with the direction of water flow in the water inlet pipe 20.

This is beneficial to the formation of a negative pressure zone at the air outlet 34, which is conducive to the formation of uniform bubbles. It also helps to reduce the impact between the airflow and the water flow, reducing the impact on the water flow velocity. At the same time, it avoids insufficient negative pressure when the water flow velocity in the water inlet pipe 20 is slow, thus preventing water from exiting the air inlet pipe 30.

[0068] The water inlet pipe 20 is a circular pipe, and the air outlet section 31 is a circular pipe. Preferably, the axis of the air outlet section 31 is arranged to coincide with the axis of the water inlet pipe 20, so that the gas entering the water inlet pipe 20 from the air outlet 34 can be evenly distributed radially in the direction of water flow.

[0070] The inner diameter of the water inlet pipe 20 is much larger than the inner diameter of the air inlet pipe 30. Preferably, the ratio of the inner diameter of the water inlet pipe 20 to the inner diameter of the air inlet pipe 30 is 8 to 25; more preferably, the ratio is 10 to 15. The ratio of the length of the air outlet section 31 to the length of the air inlet section 32 is 2 to 10, preferably 6.

[0071] An air inlet hole 22 is provided on the wall of the water inlet pipe 20, and an air inlet pipe 30 is sealed and connected to the air inlet hole 22.

The shower device also includes an inlet valve for controlling the water supply and stopping of the water supply in the water inlet pipe 20, and the inlet valve is connected and fixed to the water inlet pipe 20.

[0072] In this embodiment, an axially extending partition 35 is provided within the air outlet section 31. The partition 35 separates the flowing gas, which then mixes with the water in the water inlet pipe 20 to form microbubbles. The partition 35 divides the internal space of the air outlet section 31 into multiple gas channels 36, allowing the gas to be diverted into these channels, which is beneficial for forming stable microbubbles, increasing the number of bubbles, and improving the detergent's solubility. Furthermore, the axial extension of the partition 35 within the air outlet section 31 also helps to improve the structural strength of the air outlet section 31. Preferably, the partition 35 has multiple radially arranged baffles, which helps to divide the internal space of the air outlet section 31 into multiple gas channels 36 with equal cross-sectional areas, thus facilitating the formation of more microbubbles.
