Description

Technical Field

[0001] The invention belongs to the technical field of water valves, and in particular relates to an electric water valve and a washing device thereof. Background Art

[0002] As the functions of washing equipment increase, it has brought great convenience to people's daily life and has become one of the indispensable electrical appliances in people's lives. Water valves are often used for water inlet to washing equipment. The internal valve core is used to control the on and off of water flow. Existing water valves are generally equipped with filters to filter out large solid particles in the water. Since the water generally contains impurities such as mud and rust from the pipes, once these impurities enter the washing machine, they will not only damage the clothes, but also the washing machine.

[0003] Chinese patent application number 200710164457.6 discloses a water purification filter valve, including a hand wheel, a valve body, a valve stem, a valve core, a reversing structure and a filtering structure. The reversing structure includes a pressure plate fixed at the lower end of the valve core and a sewage discharge sealing rod coaxially arranged with the valve stem. The backwash port is located directly above the pressure plate, and the sealing port is located directly below the pressure plate. Sealing gaskets are respectively provided on the upper and lower sides of the pressure plate; the filtering structure includes a filter screen, activated carbon and triiodine resin.

[0004] In the above technical solution, a filter, activated carbon and triiodine resin are arranged to filter the incoming water, and the filter holes of the filter are relatively large, and can only filter out large particles of impurities. The triiodine resin is mainly used to disinfect and sterilize the incoming water, and cannot play a role in fine filtration. Therefore, there are still impurities such as rust and mud in the water inlet pipe that cannot be filtered in time. Once impurities such as rust and mud enter the washing equipment, they will affect the washing equipment and clothes.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. On the one hand, the present invention provides an electric water valve, which realizes fine filtration of incoming water by arranging a filtering structure in the valve body, thereby preventing impurities such as mud, rust, etc. in the water inlet pipe from entering the washing device and affecting the washing device and the clothes in the washing device; by controlling the movable part in the valve cavity to move away from or close to the water inlet, thereby connecting or disconnecting the water path between the valve cavity and the water outlet, the on and off of the water inlet can be controlled.

[0021] Alternatively, the water outlet is arranged on the inner wall of the valve cavity, and the inner wall of the valve cavity around the water outlet cooperates with the water outlet to form a trumpet shape, which is adapted to the shape of the ball valve. When the ball valve blocks the water outlet, it abuts against the inner wall of the valve cavity to seal the water outlet.

[0022] Furthermore, the second adsorption part is a permanent magnet or an iron block, and the first adsorption part is an electromagnet.

[0023] Furthermore, the filtering structure comprises:

[0025] The first filter cotton and the first activated carbon are both arranged in the water inlet, located at one end close to the ball valve, and the first activated carbon is arranged between the two first filter cottons.

[0026] Furthermore, the water inlet end of the valve body extends outside the valve body to form a water inlet joint, the filter screen is detachably arranged in the water inlet joint, the water inlet end extends into the valve cavity, and a water inlet is defined between the two ends. The first filter cotton and the first activated carbon are arranged in the water inlet extending to one end of the valve cavity.

[0027] Furthermore, the filtering structure further includes:

[0028] The second filter cotton and the second activated carbon are both arranged in the water outlet, and the second activated carbon is arranged between the two second filter cottons.

[0029] Another aspect of the present invention provides a washing device applied to the above electric water valve.

[0030] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0032] A trumpet-shaped structure is arranged at one end of the water outlet extending into the valve cavity, which is adapted to the shape of the ball valve to ensure that the ball valve cooperates with the end trumpet mouth to seal the water outlet when blocking the water outlet, thereby improving the sealing performance of the ball valve and the trumpet-shaped end water outlet.

[0033] Alternatively, the water outlet is arranged on the inner wall of the valve cavity, and the inner wall of the valve cavity around the water outlet cooperates with the water outlet to form a trumpet-shaped shape, which is adapted to the shape of the ball valve, thereby ensuring that when the ball valve blocks the water outlet, it cooperates with the inner wall of the valve cavity around the water outlet and the water outlet to form a trumpet-shaped seal.

[0034] A first filter cotton and a first activated carbon are arranged inside the water inlet, and the first filter cotton is used to achieve fine filtration of the incoming water to prevent impurities such as rust and mud in the water inlet pipe from entering the washing equipment and affecting the performance of the washing equipment.

DETAILED DESCRIPTION

[0040] 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.

[0042] 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.

[0043] like Figure 1 As shown, an electric water valve of the present invention is applied to a washing machine as an example, comprising a valve body 1 and a valve cavity 10 arranged in the valve body 1, a water inlet 16 and a water outlet 18 are arranged on the valve body 1, the water inlet 16 and the water outlet 18 are respectively communicated with the valve cavity 10, a filtering structure is arranged in the valve body 1, and the filtering structure is used for filtering the water entering the outer barrel of the washing machine to prevent the mud, rust and other impurities in the water inlet pipe from entering the washing device and affecting the washing device and the clothes in the washing device; a movable part 2 that can move back and forth inside the valve body 1 is also arranged in the valve cavity 10, and the movable part 2 in the valve cavity 10 is controlled to move away from the water outlet 18 to connect the water path between the valve cavity 10 and the water outlet 18, or the movable part 2 in the valve cavity 10 is controlled to move toward the water outlet 18 to disconnect the water path between the valve cavity 10 and the water outlet 18, so as to quickly respond to control the on and off of water inlet.

[0044] Furthermore, the valve body 1 further comprises a first adsorption portion 14 and a reset portion 15. The first adsorption portion 14 provides a first force to drive the movable portion 2 to move in a direction away from the water outlet 18, so that the water outlet 18 is communicated with the valve cavity 10, and at the same time, the water path between the water inlet 16 and the water outlet 18 in the valve cavity 10 is communicated, and the incoming water flows into the valve cavity 10, is filtered by the filtering structure, and is discharged from the water outlet 18. The reset portion 15 provides a second force opposite to the first force, and the second force drives the movable portion 2 to move in the direction of the water outlet 18 to block the water outlet 18, so that the water outlet 18 is separated from the valve cavity 10, and at the same time, the water path between the water inlet 16 and the water outlet 18 of the valve cavity 10 is cut off.

[0045] The valve body 1 is provided with a hollow protrusion 17, and the first adsorption portion 14 and the reset portion 15 can be arranged in the protrusion 17 or in the valve cavity 10 in the valve body 1. Alternatively, the first adsorption portion 14 is arranged outside the valve body 1.

[0046] Further, the movable part 2 includes a blocking part 21 and a second adsorption part 22. The blocking part 21 is movably arranged in the direction from the water outlet 18 to the inside of the valve cavity 10. The blocking part 21 is arranged in the direction from the water outlet 18 to the inside of the valve cavity 10, so that the water path between the water inlet 16 and the water outlet 18 in the valve cavity 10 is connected; the blocking part 21 is arranged in the direction from the water outlet 18 to the inside of the valve cavity 10, so that the water path between the water inlet 16 and the water outlet 18 in the valve cavity 10 is disconnected. One end of the second adsorption part 22 is connected to the blocking part 21. After receiving the force applied by the first adsorption part 14, the blocking part 21 is driven to move in the valve cavity 10 in the direction away from the water outlet 18. The reset part 15 is cooperatively connected with the other end of the second adsorption part 22 to guide the reciprocating movement direction of the movable part 2, and always keep the movable part 2 moving on the predetermined moving trajectory.

[0047] Furthermore, the blocking portion 21 is a ball valve, and the second adsorption portion 22 is a column protruding from the ball valve. The second adsorption portion 22 is radially arranged on the ball valve and is connected with the reset portion 15. The reset portion 15 is a spring sleeved on the second adsorption portion 22. One end of the spring is connected to the valve body 1, and the other end can abut against the ball valve. Since the spring is sleeved on the outer periphery of the second adsorption portion 22, it can provide a guiding effect during the movement of the movable portion 2. When the water inlet stops, the first adsorption portion 14 is controlled to stop providing the first force. At this time, the spring provides a reverse elastic force to drive the ball valve to drive the second adsorption portion 22 to move in the direction of the water outlet 18, blocking the water outlet 18, and completing the reset to disconnect the water outlet waterway.

[0048] Furthermore, one end of the water outlet 18 extending into the valve cavity 10 is trumpet-shaped, which is adapted to the shape of the ball valve. On the one hand, the contact surface between the ball valve and the end trumpet mouth is matched, and the ball valve is reset under the elastic force of the spring. When the water outlet 18 is blocked, it cooperates with the end trumpet mouth to seal the water outlet 18, thereby improving the sealing performance between the ball valve and the trumpet-shaped end water outlet 18; on the other hand, when the ball valve is driven by the elastic force of the spring, the end trumpet mouth also plays a guiding role for the ball valve during the reset process.

[0049] Furthermore, the water outlet 18 is arranged on the inner wall of the valve cavity 10, and the inner wall of the valve cavity 10 around the water outlet 18 cooperates with the water outlet 18 to form a trumpet shape, which is adapted to the shape of the ball valve. The ball valve is reset under the elastic force of the spring, and when the water outlet 18 is blocked, it abuts against the inner wall of the valve cavity 10 to seal the water outlet 18.

[0050] Furthermore, the portion of the ball valve corresponding to the sealing water outlet 18 is made of elastic material, or a rubber layer is provided on the partial spherical surface of the ball valve corresponding to the sealing water outlet 18; preferably, the ball valve is a rubber ball or a sphere wrapped with a rubber layer, and when the spring provides elastic force to drive the ball valve to seal the water outlet 18, the ball valve can seal the water outlet 18.

[0051] Furthermore, the first adsorption part 14 in the present invention can be an electromagnet, and the second adsorption part 22 can be a permanent magnet or an iron block. Taking the permanent magnet as an example, the principle of magnetic attraction is used to drive the movable part 2 to move. When the washing machine needs to take in water, the electromagnet is energized, and the permanent magnet is enhanced due to the magnetism of the electromagnet, and the attraction is increased. The attraction overcomes the combined force of the spring elastic force, the gravity of the ball valve and the water pressure in the valve body 1 on the ball valve, and the second adsorption portion 22 drives the ball valve to move in the direction away from the water outlet 18 until the permanent magnet and the electromagnet are adsorbed, and at the same time the water outlet 18 is connected to the valve cavity 10, that is, the water path between the water inlet 16 and the water outlet 18 is connected, and the washing machine starts to take in water; when the water inlet stops, the control electromagnet is de-energized, and the ball valve descends in the radial extension direction of the permanent magnet under the combined force of gravity, water pressure and the elastic force provided by the spring, and moves toward the water outlet 18. When the ball valve abuts and blocks the water outlet 18, the water outlet 18 is separated from the valve cavity 10, and the water path between the water inlet 16 and the water outlet 18 is disconnected, and the washing machine stops taking in water.

[0052] Furthermore, the filtering structure includes a filter screen 11, a first filter cotton 12 and a first activated carbon 13. The filter screen 11 is arranged in the water inlet 16, at the end away from the ball valve, the first filter cotton 12 and the first activated carbon 13 are also arranged in the water inlet 16, at the end close to the ball valve, and the first activated carbon 13 is arranged between the two first filter cottons 12, that is, the water flow at the water inlet 16 is initially filtered through the filter screen 11 to filter out large particles of solid impurities in the water flow, and then the inlet water is finely filtered through the first filter cotton 12 to filter out impurities such as rust and sand in the water inlet pipe, and the first activated carbon 13 is used to remove the odor in the inlet water.

[0053] Furthermore, the water inlet end of the valve body 1 extends outside the valve body 1 to form a water inlet joint, and the filter screen 11 is detachably arranged in the water inlet joint. The filter screen 11 is made of stainless steel and has an arched structure, which ensures that the filter screen 11 can withstand a large amount of pressure and improve the stability of the structure. The water inlet end extends into the valve cavity 10, and a water inlet 16 for water inlet is defined between the two ends. The first filter cotton 12 and the first activated carbon 13 are arranged in the water inlet 16 extending to one end of the valve cavity 10.

[0054] Furthermore, the filtering structure also includes a second filter cotton 19 and a second activated carbon 20, both of which are arranged in the water outlet 18. The second activated carbon 20 is arranged between the two second filter cottons 19. The water flow is once again finely filtered before flowing out of the water outlet 18 to achieve double filtration, thereby preventing the movable part 2 from being used for a long time to produce impurities such as rust to pollute the water flow.

[0055] When the electric water valve of the present invention is working, the electromagnet is controlled to be energized, the magnetism of the electromagnet is enhanced, the attraction is increased, and the attraction overcomes the combined force of the spring elastic force, the gravity of the ball valve and the water pressure in the valve body 1 on the ball valve, and the second adsorption portion 22 drives the ball valve to move in the direction away from the water outlet 18 until the second adsorption portion 22 is adsorbed with the first adsorption portion 14, and at the same time the water outlet 18 is communicated with the valve cavity 10, and the water path between the water inlet 16 and the water outlet 18 is connected. At this time, the washing machine starts to take in water, and the water flows through the filter screen 11 set in the water inlet joint and the first filter cotton 12 set at the water inlet 16 in sequence. The first activated carbon 13 between the two first filter cottons 12 completes preliminary filtration, and the water flows from the second filter cotton 19 at the water outlet 18 and the second activated carbon 20 between the two second filter cottons 19 and is discharged after being filtered again; when the water inlet is stopped, the electromagnet is controlled to be powered off, and the ball valve descends along the radial extension direction of the permanent magnet under the combined action of gravity, water pressure and the elastic force provided by the spring, and moves toward the water outlet 18. When the ball valve abuts and blocks the water outlet 18, the water outlet 18 is separated from the valve cavity 10, and the water path between the water inlet 16 and the water outlet 18 is disconnected, and the water inlet of the washing machine is stopped at this time.

[0056] The electric water valve of the present invention is applied to washing equipment, mainly taking a washing machine as an example, but not limited to a washing machine.

[0057] The present invention has the following beneficial effects: by arranging a filtering structure in the valve body 1, fine filtration of the incoming water is achieved, thereby preventing impurities such as mud, rust, etc. in the water inlet pipe from entering the washing device and affecting the washing device and the clothes in the washing device; by controlling the movable part 2 in the valve cavity 10 to move away from the water outlet 18 so as to connect the water path between the valve cavity 10 and the water outlet 18, or by controlling the movable part 2 in the valve cavity 10 to move toward the water outlet 18 so as to disconnect the water path between the valve cavity 10 and the water outlet 18, the on and off of the incoming water can be controlled.

[0058] The end portion of the water outlet 18 extending into the valve cavity 10 is provided with a trumpet-shaped structure, which is adapted to the shape of the ball valve, so as to ensure that the ball valve seals the water outlet 18 with the trumpet-shaped end portion to seal the water outlet 18, thereby improving the sealing performance between the ball valve and the trumpet-shaped end water outlet 18;

[0059] Alternatively, the water outlet 18 is arranged on the inner wall of the valve cavity 10, and the inner wall of the valve cavity 10 around the water outlet 18 cooperates with the water outlet 18 to form a trumpet-mouth shape, which is adapted to the shape of the ball valve, thereby ensuring that when the ball valve blocks the water outlet 18, it cooperates with the inner wall of the valve cavity 10 around the water outlet 18 and the water outlet 18 to form a trumpet-mouth seal.

[0060] A first filter cotton 12 and a first activated carbon 13 are arranged inside the water inlet 16, and the first filter cotton 12 is used to achieve fine filtration of the incoming water to prevent impurities such as rust and mud in the water inlet pipe from entering the washing equipment and affecting the performance of the washing equipment; a second filter cotton 19 and a second activated carbon 20 are arranged inside the water outlet 18 to achieve double fine filtration of the incoming water, and the activated carbon is used to remove the odor of the incoming water.

[0061] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as above in the preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
