Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and in particular relates to a clothes treating agent box and a washing machine having the clothes treating agent box. Background Art

[0002] In order to improve the washing effect, the washing machine needs to be used with clothing treatment agents, such as detergents, softeners, etc., when it is working. Existing washing machines are generally provided with siphon-type clothing treatment agent boxes. Figure 1 As shown, the laundry treatment agent box includes a box body 01 and a box cover 02 buckled on the box body 01, a siphon tube 04 is provided at one end of the box body 01, and a siphon structure is provided inside the box body 01, and the siphon structure has a drain pipe 051 provided at the bottom of the box body 01 and a siphon cap 052 sleeved on the outside of the drain pipe 051. After the treatment agent is added to the treatment agent box, water is injected into the laundry treatment agent box through the siphon tube 04, the water dissolves the laundry treatment agent, and the laundry treatment agent flows out from the drain pipe 051 through the siphon effect of the siphon structure.

[0003] When the user uses the washing machine, he first adds the clothing treatment agent to the clothing treatment agent box. There are the following problems: 1. Since the clothing treatment agent has a certain viscosity, especially the higher viscosity of the softener, the water quickly reaches the siphon water level after entering from the siphon tube 04 and is discharged from the siphon structure, resulting in the clothing treatment agent not being fully diluted; 2. When the siphon occurs, the clothing treatment agent enters the siphon structure from the siphon port formed by the siphon cap 052 and the bottom of the box body 01, which easily causes the clothing treatment agent to accumulate and remain at the siphon port, and cannot be added to the washing machine barrel, affecting the washing effect of the clothes. 3. When the water pressure of the water inlet is unstable, it often happens that the liquid in the clothing treatment agent is siphoned, but the water inlet pipe is still taking in water, resulting in repeated siphoning. If a small amount of water enters after a siphon is completed and does not reach the siphon water level, water will accumulate in the clothing treatment agent. 4. The water flowing into the clothing treatment agent box is mixed with bubbles, and the liquid in the siphon is often interrupted by the bubbles, causing the siphon to stop; subsequently, the bubbles may burst and the siphon continues, resulting in incorrect addition of clothing treatment agent and affecting the washing effect.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0019] Furthermore, a positioning portion covering the outer side of the extension edge is further provided on the assembly block, and the lower portion of the extension edge is located in a groove surrounded by the plug protrusion, the assembly body and the positioning portion.

[0020] Furthermore, the siphon cap comprises a siphon cap body, a matching block and a connecting portion connecting the siphon cap body and the matching block.

[0021] Furthermore, a limiting portion for limiting the upward and downward movement of the siphon cap is provided in the accommodating cavity, and an extension opening for the connecting portion to extend out is provided on the limiting portion.

[0022] Furthermore, a limiting guide groove for guiding the up and down movement is provided on the siphon cap, and a limiting guide column matching the limiting guide groove is provided on the limiting portion, and the limiting guide column is located in the limiting guide groove.

[0044] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0045] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", etc. are based on the positional relationships shown in the drawings. The terms are only used to facilitate the description of the present invention and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention.

[0046] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like 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, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] See also Figure 2-Figure 11 , is an embodiment of the laundry treatment agent box proposed by the present invention, the laundry treatment agent box 10 is arranged on the washing machine, and is used to add washing water into the washing tub of the washing machine. The laundry treatment agent box 10 comprises: a box body 1 and an upper cover 2, at least one accommodating cavity 11 is arranged in the box body 1, the upper cover 2 is arranged above the box body 1, and a water inlet waterway 21 for supplying water to the accommodating cavity 11 is arranged on the upper cover 2. First, the laundry treatment agent is added into the accommodating cavity 11, and then tap water is added into the accommodating cavity 11 through the water inlet waterway 21 to dilute and dissolve the laundry treatment agent in the accommodating cavity 11, and then flow into the washing tub of the washing machine.

[0048] A siphon structure 3 is provided in the accommodating chamber 11 to enable the liquid in the accommodating chamber 11 to flow out through siphoning; when a plurality of accommodating chambers 11 are provided in the box body 1, a water inlet channel corresponding to each accommodating chamber 11 is provided on the upper cover 2, and the siphon structure 3 can be provided in one accommodating chamber 11, or in a plurality of accommodating chambers 11. The siphon structure 3 comprises a siphon tube 31 provided at the bottom of the accommodating chamber 11, and a siphon cap 32 sleeved on the siphon tube 31, and a gap is provided between the siphon tube 31 and the siphon cap 32 to form a siphon flow path 30, through which the liquid in the accommodating chamber 11 can flow into the washing tub.

[0049] In this embodiment, the siphon cap 32 is arranged to be movable up and down, so that the siphon flow path 30 can be opened or closed, or the siphon flow path 30 can be unobstructed or cut off, so as to realize siphon water inlet and overflow water inlet after siphon failure. The siphon cap 32 can be moved up and down, so that the siphon flow path 30 between the siphon cap 32 and the siphon tube 31 can be adjusted; when the siphon cap 32 moves downward, so that the siphon cap 32 contacts the siphon tube 31, or the siphon cap 32 contacts the bottom of the accommodating chamber 11, the siphon flow path 30 is cut off, or the siphon flow path 30 is closed, that is, the siphon fails. At this time, the water flowing into the accommodating chamber 11 through the water inlet waterway 21 reaches the overflow water level, and water enters through overflow. After the siphon cap 32 moves upward and resets, the siphon flow path 30 is connected, and water inlet is now siphon. By moving the siphon cap 32 up and down, the switching between siphon water inlet and overflow water inlet can be realized. In the overflow water inlet stage, the water level in the accommodating chamber 11 is relatively high, which is conducive to the full dilution and dissolution of the clothing treatment agent and reduces the residual clothing treatment agent; and through the overflow water inlet, the clothing treatment agent is avoided from gathering at the siphon structure 30, thereby avoiding the blockage of the siphon flow path 30; the siphon can be set to fail during the water inlet stage to avoid the siphon being affected by the water inlet bubbles, and to avoid the siphon from being carried out too early and too fast, thereby solving the problem of water accumulation in the clothing treatment agent box after the washing machine ends; and the structure is simple and easy to implement.

[0050] In this embodiment, the siphon cap 32 is pushed downward by setting a pushing waterway 22. Specifically, a pushing waterway 22 for pushing the siphon cap 32 is provided on the upper cover 2, and the siphon cap 32 is assembled on the pushing waterway 22. When the pushing waterway is opened, water with a certain pressure flows into the pushing waterway, and the water pressure is used to push the siphon cap 32 downward, so that the siphon flow path 30 is closed and the siphon fails. At this time, water is injected into the accommodating chamber 11, and it can flow out through overflow, that is, it flows into the washing tub through overflow, which is overflow water inflow. By setting the pushing waterway 22 and using water pressure to push the movement of the siphon cap 32, the pushing structure is simple and easy to control, and no electric actuator is used, so no power is needed. Since water needs to be injected into the clothing treatment agent box, if an electric actuator is set, waterproofing needs to be set, which will complicate the structure, increase the cost, and increase the control of the electric actuator.

[0051] See also Fig.11As shown, the water inlet waterway 21 and the driving waterway 22 can be arranged in parallel to realize separate control, that is, switch solenoid valves are arranged in both the water inlet waterway 21 and the driving waterway 22. After the water inlet waterway 21 is opened, water is poured into the accommodating chamber 11. At this time, siphoning is not desired, and overflow water inlet is set, that is, siphon failure occurs, and the siphon cap 32 needs to move downward; after the water inlet waterway 21 is closed, in order to flow the washing water in the accommodating chamber 11 into the washing tub, siphoning is required, and the siphon cap 32 needs to be reset at this time; that is, after the water inlet waterway 21 is opened, the driving waterway 22 is also opened, and the siphon cap 32 is pushed downward by water pressure to close the siphon flow path 30; after the water inlet waterway 21 is closed, the driving waterway 22 is also closed, so that the siphon cap 32 is reset, so that the siphon flow path 30 is unblocked; preferably, the opening and closing of the driving waterway 22 and the water inlet waterway 21 are set to be linked control. When the water inlet waterway 21 is opened, the push waterway 22 is also opened, and when the water inlet waterway 21 is closed, the push waterway is also closed. It is more preferred to set the push waterway 22 to be connected with the water inlet waterway 21, and a switch electromagnetic valve can be set, which is conducive to simplifying the structure and reducing costs.

[0052] After the water inlet waterway 21 is opened, the push waterway 22 is also opened, the siphon cap 32 moves downward, and the siphon flow path 30 between the siphon cap 32 and the siphon tube 31 is closed. At this time, water is overflowed; after the water inlet waterway 21 is closed, the push waterway 22 is also closed. At this time, water is siphoned.

[0053] To achieve the up and down movement of the siphon cap 32, other various methods can also be used, for example, a telescopic motor is set on the upper cover 2, and the siphon cap 32 is pushed downward by extending the output shaft; or a driving motor plus a connecting rod structure is set to push the siphon cap 32 downward, so that the siphon fails.

[0054] See also Figure 5-Figure 8 As shown, a matching block 323 matching with the driving waterway 22 is provided on the siphon cap 32, and a receiving groove 221 matching with the matching block 323 is provided at the end of the driving waterway 22, and the matching block 323 is assembled at the open end of the receiving groove 221 so as to be movable up and down; after the driving waterway 22 is opened, the water pressure in the receiving groove 221 pushes the matching block 323 to move downward. The matching block 323 forms a part of the driving waterway 22, and the water pressure directly acts on the matching block 323, which is conducive to pushing the movement of the siphon cap 32.

[0055] Specifically, the accommodating groove 221 is provided with an extension edge 2211 extending downward, the matching block 323 has an assembly body 3231, a plug convex portion 3232 protruding along the assembly body 3231 toward the accommodating groove 221, and the extension edge 2211 is sleeved on the outer side of the plug convex portion 3232; the water pressure acts on the plug convex portion 3232, which can push the plug convex portion 3232 to move downward, thereby driving the entire siphon cap 32 to move downward, that is, the plug convex portion 3232 can move up and down along the extension edge 2211; the siphon cap 32 is pushed by the water pressure, and there is mutual movement between the plug convex portion 3232 and the extension edge 2211, and the two can be arranged without being sealed; the accommodating groove 221 is located above the accommodating cavity 11, even if water leaks out from between the plug convex portion 3232 and the extension edge 2211, the outflowing water falls into the accommodating cavity 11; as long as the water pressure in the accommodating groove 221 can push the siphon cap 32 to be in a stable state, the failure of the siphon can be ensured.

[0056] Of course, a sealing arrangement can also be provided in which the plug protrusion 3232 and the extension edge 2211 can be moved up and down to prevent the water in the water channel 22 from leaking out of the gap between the plug protrusion 3232 and the extension edge 2211, thereby ensuring the water pressure in the receiving groove 11.

[0057] A positioning portion 3233 is also provided on the assembly block 323, which is covered on the outside of the extension edge 2211. The lower part of the extension edge 2211 is located in a groove surrounded by the plug protrusion 3232, the assembly body 3231 and the positioning portion 3233. The extension edge 2211 is used to limit the extension edge 2211 to avoid deformation of the extension edge 2211 due to water pressure, thereby ensuring the stability of the matching block 323 and the accommodating groove 221 after assembly.

[0058] The siphon cap 32 comprises a siphon cap body 321, a matching block 323 and a connecting portion 322 connecting the siphon cap body 321 and the matching block 323. A limiting portion 12 for limiting the upward and downward movement of the siphon cap 32 is provided in the accommodating cavity 11, and an extension port 121 for the connecting portion 322 to extend is provided on the limiting portion 12; the limiting portion 12 is used to ensure that the siphon cap 32 moves downward when subjected to pressure, thereby ensuring the truncation of the siphon flow path 30 and rendering the siphon ineffective. Specifically, the limiting portion 12 has a transverse supporting portion 120 arranged on the cavity wall of the accommodating cavity 11, and the extension port 121 is arranged on the supporting portion 120. At least two circumferentially evenly distributed limiting guide columns 123 are provided on the supporting portion 120, and a downwardly extending limiting guide groove 3234 is provided on the matching block 323 of the siphon cap 32, and the limiting guide column 123 is located in the limiting guide groove 3234; the movement stability of the siphon cap 32 is ensured, and the deviation of the siphon cap 32 is avoided, resulting in the siphon cap 32 not contacting the siphon tube 31 after moving downward, so that the siphon flow path 30 is closed.

[0059] In this embodiment, the support portion 120 is a horizontally arranged support rod, and is provided with two limiting guide columns 123. The limiting guide groove 3234 is a groove with a lower opening. In order to achieve the reset of the siphon cap 32 after moving downward, a reset spring 33 is provided in the limiting guide groove 3234.

[0060] The box body 1 is also provided with a flow chamber 13 located below the accommodating chamber 11. The siphon tube 31 is connected to the flow chamber 13, that is, the liquid in the accommodating chamber 11 flows into the flow chamber 13 through the siphon flow path 30. The rear side of the flow chamber 13 is provided with a liquid outflow port. By providing the flow chamber 13, it is advantageous to arrange the liquid outflow port of the box body 1 at the rear end, so as to avoid the residual liquid in the siphon flow path 30 from falling outside the washing machine when the box body 1 is pulled out. It is preferred that the bottom surface of the flow chamber 13 is arranged to be inclined, and the liquid outflow port is located at the lower end, so as to accelerate the flow speed of the liquid and avoid water accumulation.

[0061] See also Figure 2-Figure 11 As shown, the working method of the laundry treatment agent box in this embodiment is described, which has the following steps:

[0062] S10. Adding a laundry treatment agent to the accommodating chamber 11;

[0063] S20. When water is required into the laundry treatment agent box 10, the water inlet waterway 21 is controlled to open, and the waterway 22 is also pushed to open at the same time, and the water overflows;

[0064] Specifically, after the water inlet waterway 21 is controlled to be opened, the water inlet waterway 21 and the driving waterway 22 are linked and controlled, so that the driving waterway 22 is also opened at the same time, and the water pressure pushes the siphon cap 32 to move downward, making the siphon ineffective. Tap water is injected into the receiving chamber 11 through the water inlet waterway 21. As the water flows in, the water level in the receiving chamber 11 increases, and the clothing treatment agent in the clothing treatment agent box 10 is dissolved and diluted; when the water level in the receiving chamber 11 reaches the overflow water level, the liquid in the receiving chamber 11 begins to overflow and flows into the washing tub, which is the overflow water inlet stage.

[0065] S30. Water inlet ends, siphon water inlet;

[0066] Specifically, when the water level in the washing tub reaches the set water level, the water inlet waterway 21 is controlled to be closed, the water inlet ends, no water is added to the accommodating chamber 11, and the overflow ends; when the water inlet waterway 21 is closed, the waterway 22 is also closed at the same time, so that the water pressure in the accommodating tank 221 cannot ensure that the siphon cap 32 is in a low position, and under the elastic force of the reset spring 4, the siphon cap 32 moves upward to achieve reset, so that the siphon flow path 30 is connected; the liquid in the accommodating chamber 11 flows into the washing tub through siphoning. At this time, the water inlet has ended and there are no water inlet bubbles, so that the siphon flow path is smooth, ensuring that the liquid in the accommodating chamber 11 can flow into the washing tub through siphoning, greatly reducing the residual liquid in the accommodating chamber 11.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents.
