Description

Technical Field

[0001] The present invention relates to the field of washing machines, in particular to a washing additive dispensing device used in washing machines, in particular to a washing additive dispensing device with a multi-channel siphon cap, and also to a washing machine equipped with the washing additive dispensing device. Background Art

[0002] The detergent additive dispensing device of the washing machine currently on the market generally consists of a detergent additive box installed in a water box. The detergent additive box is provided with a plurality of independent chambers for dispensing different types of detergent additives. The detergent additives can be any existing reagent added during clothing processing; for example: detergent, rinse agent, softener, etc.

[0003] At the same time, in order to prevent the detergent additives injected by the user from accidentally flowing out, a siphon structure is generally installed in the chamber, so that the user can manually inject different types of detergent additives into the chamber. The liquid level of the detergent additive is lower than the siphon liquid level of the siphon structure, so that the detergent additive can be temporarily stored in the chamber; when the detergent additive needs to be added to the drum later, water is added to the chamber, and the liquid level in the chamber reaches the siphon liquid level by the water, thereby triggering the siphon effect of the siphon structure, and the detergent additive and water mixture in the chamber is added to the drum through the siphon structure.

[0004] However, the delivery device using the above siphon structure has the following problems:

[0005] At the end of the dosing, when the liquid level in the chamber is lower than the inlet height of the siphon structure, gas will enter the siphon channel, causing the siphon effect to terminate; at this time, the remaining liquid in the chamber and the siphon channel will remain in the chamber, causing problems such as liquid residue in the chamber and inaccurate dosing of detergent additives; in particular, when the washing machine is not used for a long time, the residual liquid in the chamber will cause scabs and even block the inlet end of the siphon channel.

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] like Figure 1As shown, an embodiment of the present invention introduces a washing additive dispensing device and a washing machine with a multi-channel siphon cap structure, wherein the washing machine comprises a shell 200, in which a drum is installed, and the drum may be an inner and outer drum structure in which the inner and outer drums are sequentially nested, or may be a single hole-free drum having both the functions of rotary washing and water holding; the drum generally has a horizontal axis or is slightly inclined upward toward the drum mouth; the drum mouth is correspondingly arranged on the front side of the shell, and the front side of the shell has a clothing delivery port, which is opened opposite to the drum mouth; an outwardly openable door body 100 is arranged on the front side of the shell 200, and the door body 100 corresponds to the clothing delivery port arranged on the opening and closing shell 200, and is used to achieve the purpose of delivering clothing to be processed into the drum or taking clothing out of the drum by opening and closing the door body.

[0042] In the embodiment of the present invention, a protrusion protruding toward the inside of the shell body 200 is provided on the door body 100 of the washing machine on the side facing the inside of the shell body 200, and the outer periphery of the protrusion corresponds to the clothing delivery port and is closed and shielded to prevent the clothing in the drum from entering the drum port; a hollow cavity extending vertically downward and open at the top is provided on the top of the protrusion of the door body 100, and the above-mentioned hollow cavity constitutes a delivery chamber 1; an outlet is provided at the bottom of the delivery chamber, and the outlet is connected with the delivery port 5 opened on the door body 100 toward the inside of the drum through a pipeline; the top opening of the delivery chamber 1 constitutes a washing additive injection port 4 for the user to inject washing additives; at the same time, a nozzle opened toward the washing additive injection port 4 is provided on the shell body 200 of the washing machine, or a water pipe connected to the washing additive injection port is provided on the door body 100, so that the water flow of the washing machine can be introduced into the delivery chamber 1 through the above-mentioned nozzle or water pipe, and water is introduced into the drum through the delivery port 5 or a washing additive mixture is delivered.

[0043] In the embodiment of the present invention, in order to prevent the washing additive injected into the delivery chamber 1 by the user from directly flowing out from the outlet 101, a siphon tube 3 is provided in the delivery chamber 1, the lower end of the siphon tube 3 is connected to the bottom wall of the delivery chamber and is located at the periphery of the outlet 101, the siphon tube 3 extends vertically upward, and the upper end is not lower than the maximum washing additive liquid level height of the delivery chamber, so that the outlet 101 is connected with the delivery chamber 1 through the siphon tube 3, so that the washing additive manually added into the delivery chamber 1 by the user remains in the delivery chamber 1 under the obstruction of the siphon tube 3, and then after water is subsequently added to the delivery chamber 1 until the liquid level exceeds the height of the upper end of the siphon tube 3, the washing additive flows out of the delivery chamber 1 through the siphon tube 3 and the outlet 101, thereby achieving the effect of delivering the washing additive manually injected by the user to the outside.

[0044] In the embodiment of the present invention, in order to ensure that the washing additive injected into the delivery chamber can be efficiently and smoothly discharged outward under the action of the incoming water, a siphon cap 2 is buckled on the siphon tube 3, and the siphon tube 3 and the siphon cap 2 form a siphon channel 3011, so that after the delivery chamber 1 is filled with water to a liquid level higher than the height of the siphon tube 3, the washing additive mixture or the incoming water fills the siphon channel 3011, which will trigger the siphon effect; because the height of the delivery port 5 is lower than the delivery chamber 1, the washing additive mixture or the incoming water in the delivery chamber 1 is driven by gravity to automatically flow to the outlet 101 through the siphon channel 3011, flow out of the delivery chamber 1, and be injected into the drum of the washing machine through the delivery port 5.

[0045] However, the above-mentioned process of dispensing using the siphon effect has the following problems: at the end of dispensing, when the liquid level in the dispensing chamber 1 is lower than the height of the lower end of the siphon cap 2, gas will enter the siphon channel, causing the siphon effect to fail, and the remaining liquid in the dispensing chamber 1 and the siphon channel will remain in the dispensing chamber, causing problems such as liquid residue in the dispensing chamber and inaccurate dispensing of detergent additives; in particular, when the washing machine is not used for a long time, the residual liquid in the dispensing chamber will cause scabs to form, and even block the inlet end of the siphon channel.

[0046] In the embodiment of the present invention, in order to solve the above technical problems, the following settings are performed:

[0047] like Figures 1 to 9 As shown, in the embodiment of the present invention, a partition structure is provided on the siphon cap 2 and / or the siphon tube 3, and a part of the siphon channel 3011 is divided into independent channels to form a residual liquid siphon channel 3021. By independently dividing the siphon channel part of the delivery chamber into residual liquid siphon channels, the additive mixture in the delivery chamber can be siphoned and discharged through two or more independent siphon channels, thereby improving delivery diversification; at the same time, the residual liquid siphon channel separated from the siphon channel can be siphoned and discharged for a second time after the siphon channel is discharged, thereby greatly reducing the amount of residual liquid in the delivery chamber.

[0048] In the embodiment of the present invention, the height of the liquid inlet end of the residual liquid siphon channel 3021 connected to the delivery chamber 1 is lower than the height of the liquid inlet end of the siphon channel 3011 connected to the delivery chamber 1. When the siphon channel 3011 performs siphon discharge, when the liquid level in the delivery chamber 1 drops to the height of the liquid inlet end of the siphon channel 3011 connected to the delivery chamber 1, the siphon effect of the siphon channel 3011 fails, and the additive mixture in the delivery chamber 1 can no longer be discharged outward through the siphon channel 3011; at this time, the liquid level in the delivery chamber 1 is higher than the height of the liquid inlet end of the residual liquid siphon channel 3021 connected to the delivery chamber 1, and the residual liquid in the delivery chamber 1 continues to be discharged outward through the residual liquid siphon channel 3021; ​​until the liquid level in the delivery chamber 1 drops to the height of the liquid inlet end of the residual liquid siphon channel 3021 connected to the delivery chamber 1, the amount of detergent additives remaining in the delivery chamber 1 is greatly reduced.

[0049] Through the above arrangement, after the siphon effect of the siphon channel fails, the residual liquid siphon channel can continue to be used to discharge the washing additive mixed liquid in the delivery chamber, thereby greatly reducing the residual liquid in the delivery chamber.

[0050] At the same time, in order to minimize the amount of liquid residue in the delivery chamber 1, the diameter of the residual liquid siphon channel 3021 is minimized, and the height of the inlet end of the residual liquid siphon channel 3021 is minimized, so that as much liquid as possible in the delivery chamber 1 can be discharged by the residual liquid siphon channel 3021, and the amount of liquid flowing back from the residual liquid siphon channel 3021 to the delivery chamber 1 is minimized. Preferably, the diameter of the residual liquid siphon channel 3021 is smaller than the diameter of the siphon channel 3011; more preferably, the diameter of the residual liquid siphon channel 3021 is much smaller than the diameter of the siphon channel 3011.

[0055] In an embodiment of the present invention, the outer partition 82 and the inner partition 81 are respectively located at the inner and outer tube walls of the siphon tube 3 at the same radial position; preferably, the tube diameter of the connecting channel 7 formed by the outer partition 82 is set to be the same as the tube diameter of the residual liquid siphon tube 302 formed by the inner partition 81.

By providing a downwardly concave groove on the bottom wall of the delivery chamber, the liquid in the delivery chamber can be gathered and flowed to the groove, and the siphon discharge flow rate can be increased as much as possible; at the same time, the amount of residual liquid corresponding to the siphon failure liquid level height can be reduced, and the amount of residual liquid in the delivery chamber after siphon delivery can be further reduced.

[0065] like Figures 1 to 9 As shown, in the embodiment of the present invention, water is introduced into the delivery chamber 1 by utilizing the water inlet structure of the washing machine, thereby triggering the siphon structure installed in the delivery chamber 1 to produce a siphon effect, and the washing additive mixed liquid in the delivery chamber 1 is siphoned out simultaneously through the siphon channel 3011 and the residual liquid siphon channel 3021; ​​when the mixed liquid in the delivery chamber 1 is lower than the stop liquid level line 3012 of the siphon channel, the siphon channel 3011 ends the siphoning work; the residual liquid siphon channel 3021 continues to perform the siphoning work until the mixed liquid in the delivery chamber 1 is lower than the stop liquid level line 3022 of the residual liquid siphon channel, and the residual liquid siphon channel 3021 stops the siphoning work.

[0066] In the embodiment of the present invention, the bottom of the delivery chamber 1 is located at a horizontal position below the siphon channel stop liquid level line 3012, which is slightly higher than the horizontal position below the residual liquid siphon channel stop liquid level line 3022. The delivery chamber 1 is an overall bowl-shaped structure, so that the mixed liquid flows to converge around the siphon tube 3 at the bottom of the delivery chamber 1, and the siphon channel 3011 and the residual liquid siphon channel 3021 work together to discharge the mixed liquid from the siphon channel discharge port and the residual liquid siphon channel discharge port to the delivery port 5 through the siphon effect, and then discharged into the cylinder in the shell 200 through the delivery port 5.

[0067] In the embodiment of the present invention, the channel diameter of the siphon channel 3011 is originally larger than the channel diameter of the residual liquid siphon channel 3021; ​​after the detergent additive is added into the delivery chamber 1, the water inlet structure of the washing machine feeds water into the delivery chamber 1, and the detergent additive in the delivery chamber 1 is mixed with water to form a mixed liquid, and the mixed liquid triggers the siphon effect of the siphon channel 3011 and the residual liquid siphon channel 3021, and most of the mixed liquid in the delivery chamber 1 is drawn out of the delivery chamber 1 and discharged into the drum in the shell 200 through the delivery port 5; when the liquid level of the mixed liquid drops to the stop liquid level line 3012 of the siphon channel , affected by gravity, there is still a lot of mixed liquid in the delivery chamber 1, and the residual liquid siphon channel 3021 continues to work and continues to extract the residual mixed liquid in the delivery chamber 1 from the delivery chamber 1 through the siphon effect. Because the pipe diameter of the residual liquid siphon channel 3021 is smaller than the pipe diameter of the siphon channel 3011, the suction force of the residual liquid siphon channel 3021 is stronger than that of the siphon channel 3011, and the influence of gravity is smaller than that of the siphon channel 3011, thereby further extracting and discharging the residual mixed liquid in the delivery chamber 1, thereby effectively reducing the residual liquid in the delivery chamber 1.

[0068] In the embodiment of the present invention, when a user uses a washing machine equipped with the above-mentioned washing additive dispensing device with a multi-channel siphon structure, the user opens the door 100, puts in the clothes and other items to be processed, pours the washing additives into the dispensing chamber 1 through the washing additive injection port 4, and closes the door 100; after the door 100 and the shell 200 are closed, the washing program is started; the washing machine water inlet structure located above the washing additive injection port 4 in the shell 200 supplies water to the dispensing chamber 1, so that the washing additives in the dispensing chamber 1 are mixed; when the liquid level of the mixed liquid in the dispensing chamber 1 reaches a certain height, the siphon effect of the siphon channel 3011 and the residual liquid siphon channel 3021 is triggered, and the siphon channel 3011 and the residual liquid siphon channel 3021 simultaneously supply water to the dispensing chamber 1. The mixed liquid in the delivery chamber 1 is siphoned out, flows out of the delivery chamber 1 through the outlet 101, and is discharged to the delivery port 5, and then the extracted mixed liquid is delivered into the cylinder inside the shell 200 through the delivery port 5; when the liquid level of the mixed liquid in the delivery chamber 1 drops to the siphon channel stop liquid level line 3012, the siphon channel 3011 stops siphoning, at this time, there is still a certain amount of mixed liquid or water at the bottom of the delivery chamber 1 that has not been extracted, and the residual liquid siphon channel 3021 is still performing the siphoning work until the liquid level of the mixed liquid in the delivery chamber drops to the residual liquid siphon channel stop liquid level line 3022, at which time the residual liquid siphon channel 3021 stops siphoning, at this time only a very small amount of mixed liquid and / or water remains in the delivery chamber 1, thereby achieving a significant technical progress in reducing the residual liquid in the delivery chamber.
