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 water inlet structure of the washing additive dispensing device, and also to a drum washing machine with the washing additive dispensing device installed on a door body. 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] Existing automatic detergent additive dispensing devices are generally installed on the housing of the washing machine, and use the water flow of the washing machine to dispense the extracted detergent additives into the drum of the washing machine; however, when the automatic detergent additive dispensing device is installed on the housing of the washing machine, it needs to occupy a part of the space of the housing, which will affect the overall design of the washing machine.

[0004] In order to solve the above-mentioned problem, some existing technical solutions install detergent additives on the door of the washing machine; in particular, since the door of the drum washing machine is generally arranged on the front side of the machine body, when the user opens the door to the outside and takes and places the clothes in the drum, the inside of the door can be easily operated. Therefore, some solutions have a detergent additive dispensing device on the door.

[0005] However, when the detergent additive dispensing device installed on the door body has multiple dispensing chambers for dispensing different types of detergent additives, it is necessary to install multiple water inlet channels corresponding to each other to achieve the effect of flushing and dispensing respectively in different chambers; however, the setting of too many water inlet channels not only increases the cost of the washing machine, but also squeezes the internal space of the washing machine, which is already not abundant.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a water inlet structure of a washing additive delivery device to achieve the effect of combined water inlet into different delivery chambers by interfering with water flow, thereby achieving the purpose of reducing the number of water inlet pipes and improving the accuracy of water inlet control.

[0036] A drum washing machine is introduced in an embodiment of the present invention, comprising a shell body, in which a drum structure is installed. The drum structure can be an inner and outer drum structure in which the inner and outer drums are sequentially nested, or a single hole-free drum with both the functions of rotary washing and water holding. The drum structure generally has a horizontal axis or is slightly inclined upward toward the drum opening. The drum opening is correspondingly arranged on the front side of the shell body, and the front side of the shell body has a clothing delivery port, which is opened opposite to and connected to the drum opening. An outwardly openable door body 100 is arranged on the front side of the shell body, and the door body 100 corresponds to the clothing delivery port arranged on the shell body for opening and closing, and is used to achieve the purpose of corresponding opening and closing control of the drum opening, allowing clothing to be processed to be delivered into the drum, or taking clothing out of the drum by opening and closing the door body 100.

[0038] 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 delivery port 5, 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 1 and is located at the periphery of the outlet provided on the bottom wall of the delivery chamber 1, 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 1, so that the outlet 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 introduced into the delivery chamber 1 until the liquid level exceeds the height of the upper end of the siphon tube 3, the siphon effect is triggered and the washing additive flows out of the delivery chamber 1 through the siphon tube 3 and the outlet, and finally enters the drum structure through the delivery port 5 connected with the outlet, thereby achieving the effect of delivering the washing additive manually injected into the delivery chamber 1 by the user into the drum of the washing machine.

[0039] In the embodiment of the present invention, the inner and outer cylinder structures in which the cylinder structure is sequentially set inside and outside are taken as an example for explanation, and the details are as follows:

[0040] like Figures 1 to 3As shown, a tubular window pad 200 is connected between the clothing delivery port of the housing 100 and the drum mouth of the outer drum. The window pad 200 is provided with folds to provide a shock-absorbing and buffering connection, so that the drum structure is not affected by the vibration generated by the operation of the washing machine, and the drum mouth is connected to the housing, so that the drum mouth and the clothing delivery port form a stable passage for taking and putting clothes; the front and rear ends of the tubular window pad 200 are respectively sealed and connected with the clothing delivery port and the drum mouth of the outer drum, so as to form a passage for taking clothes into and putting clothes into the drum. A nozzle 6 is installed on the window pad 200, and the nozzle 6 passes through the window pad 200 and is fixedly assembled at the passing position, so that the nozzle 6 is fixedly installed on the window pad 200; one end of the nozzle 6 outside the window pad 200 is connected to the water inlet pipe 2, and the other end that penetrates the window pad 200 has a water spray outlet 8, which is used to spray the incoming water flow toward the outer peripheral wall of the protruding portion 7 of the door body 100, and at least part of the incoming water flow directly flows into the delivery cavity 1 or flows along the outer peripheral wall of the protruding portion 7 and then flows into the delivery cavity 1.

[0041] Generally, a protrusion 7 protruding toward the inside of the drum is provided on the vertically arranged door body 100. When the door body 100 is correspondingly buckled, the protrusion 7 extends into the annular window pad 200. The interior of the protrusion 7 is hollow for the installation of a washing additive delivery device. The protrusion 7 is generally composed of a glass basin assembled on an annular frame, so that the user can observe the washing condition of the clothes inside the drum structure by using the transparent glass basin. Of course, the protrusion 7 can also be composed of other materials.

[0042] Preferably, the delivery chamber 1 is arranged at the upper part of the horizontal protrusion 7 of the vertically arranged door body 100, and the injection port 4 of the delivery chamber 1 is located at the top of the chamber and is open toward the top of the protrusion 7; the nozzle 6 is installed on the window pad 200 above the protrusion 7, and the water spray outlet 8 of the nozzle 6 is opened downward, so that part of the incoming water flow sprayed by the nozzle 6 is sprayed toward the upper top surface 9 of the outer peripheral wall of the protrusion 7 of the door body 100, so that the sprayed incoming water flow rinses the outer wall of the protrusion 7 and then flows along the outer wall of the protrusion 7 to the injection port 4, and then flows into the delivery chamber 1 through the injection port 4.

[0043] like Figures 1 to 3 As shown, in the embodiment of the present invention, the washing additive dispensing device includes: three dispensing chambers 1, namely a left dispensing chamber 11, a middle dispensing chamber 13, and a right dispensing chamber 12; each dispensing chamber 1 is provided with an injection port 4 on the top, namely a left injection port, a middle injection port, and a right injection port; the three injection ports 4 are arranged in parallel facing upward, and are sequentially arranged in the upper top surface 9 of the protruding portion 7 of the door body 100.

[0044] At the same time, the water inlet structure of the washing additive delivery device includes two water inlet pipes 2, namely a left water inlet pipe 21 and a right water inlet pipe 22; the water outlet ends of the two water inlet pipes 2 are each provided with a water spray outlet 8, namely a left water spray outlet 81 and a right water spray outlet 82; the water spray outlet 8 can be composed of the above-mentioned nozzle 6, or directly composed of the water outlet end of the water inlet pipe 2; the axes of the water spray outlets 8 of the two water inlet pipes 2 are arranged to be staggered at a certain angle, and are opened one by one toward the injection ports 4 of the delivery chambers 1 on the left and right sides, so as to spray at least part of the water flow into the delivery chamber 1 on the opposite side when water is delivered to any water inlet pipe 2, or to spray at least part of the interference water flow into the middle delivery chamber 13 when water is delivered to the two water inlet pipes 2 at the same time to generate interference.

[0045] Through the above-mentioned arrangement, the combined on-off control of the two water inlet pipes can be utilized to realize the effect of separately supplying water to the three water delivery chambers, thereby achieving the effect of controllable selective water supply to the three delivery chambers for different types of detergent additives, thereby achieving significant technical progress in simplifying the structure of the washing machine and reducing the cost of the washing machine.

[0046] In addition, by utilizing the above arrangement, when one of the two water inlet pipes is selected to supply water, water can be supplied to the left or right delivery chamber respectively; when the two water inlet pipes are supplying water at the same time, interference water flow can be utilized to supply water to the middle delivery chamber, effectively preventing the occurrence of water cross-flow between the three different delivery chambers.

[0047] In addition, by opening the water spray outlet of the water inlet pipe toward the protruding part of the door body, part of the incoming water flow does not flow directly into the injection port, but is sprayed to the outer peripheral wall of the protruding part of the door body, and the outer wall of the door body facing the barrel mouth is sprayed with the jet water flow, thereby achieving the goal of flushing the door body with the incoming water flow and preventing the occurrence of problems such as foam and detergent additives adhering to the door body.

[0048] In the embodiment of the present invention, a left injection port is provided at the top of the left delivery chamber 11, and a left water inlet pipe 21 is provided above the left injection port. The left water spray outlet 81 of the left water inlet pipe 21 is opened obliquely toward the right side, so that the axis of the left water spray outlet 81 of the left water inlet pipe 21 extends obliquely toward the lower right side and toward the right injection port provided at the top of the right delivery chamber 12. When the left water inlet pipe 21 is filled with water alone, at least part of the left water flow is directly sprayed to the right injection port and enters the right delivery chamber 12, and the right detergent additive delivered into the right delivery chamber 12 is mixed and then flows into the drum of the washing machine through the delivery port 5.

[0049] A right injection port is provided at the top of the right delivery chamber 12, and a right water inlet pipe 22 is provided above the right injection port. The right water spray outlet 82 of the right water inlet pipe 22 is opened obliquely toward the left side, so that the axis of the right water spray outlet 82 of the right water inlet pipe 22 extends obliquely toward the lower left side and toward the left injection port provided at the top of the left delivery chamber 11. When the right water inlet pipe 22 is filled with water alone, at least part of the right water flow is directly sprayed to the left injection port and enters the left delivery chamber 11, and the left washing additive delivered into the left delivery chamber 11 is mixed and then flows into the drum of the washing machine through the delivery port 5.

[0050] The axial extension line of the left water spray outlet 81 of the left water inlet pipe 21 and the axial extension line of the right water spray outlet 82 of the right water inlet pipe 22 intersect, and the intersection is located vertically above the middle injection port at the top of the middle delivery chamber 13. When the right water inlet pipe 22 and the left water inlet pipe 21 are filled with water at the same time, at least part of the right water flow and the left water flow interfere with each other to form an interference water flow. The interference water flow changes the direction of the water flow and flows directly downward to the middle injection port and enters the middle delivery chamber 13. After mixing the intermediate washing additive delivered in the middle delivery chamber 13, it flows into the drum of the washing machine through the delivery port 5.

[0051] The washing additives put into each of the above-mentioned delivery chambers 1 can be any existing one, such as: detergent, disinfectant, softener, bleach, brightener, etc.;

[0052] In an embodiment of the present invention, the types of washing additives placed in the left delivery chamber 11, the right delivery chamber 12, and the middle delivery chamber 13 can be different; for example: detergent is placed in the left delivery chamber 11, disinfectant is placed in the right delivery chamber 12, and softener is placed in the middle delivery chamber 13.

[0053] In the embodiment of the present invention, the top injection ports 4 of the three delivery chambers 1 are arranged at intervals in the left-right direction and at the same height, and the top injection ports 4 of the delivery chambers 11 and 12 on the left and right sides are symmetrically arranged with respect to the center dividing plane of the top injection port 4 of the middle delivery chamber 13 in the left-right direction; preferably, the washing additive delivery device is arranged on the door body 100 of the washing machine, and the center dividing plane of the middle delivery chamber 13 is arranged coplanar with the vertical center dividing plane of the door body 100.

[0054] In the embodiment of the present invention, the water spray outlets 8 of the two water inlet pipes 2 are located in the same vertical plane and are symmetrically arranged relative to the above-mentioned middle dividing plane, so that the water flow sprayed by the left and right water inlet pipes 2 can be correspondingly sprayed into the right and left delivery chambers on the opposite sides, thereby achieving the effect of mixing and delivering the washing additives in the delivery chamber 1 on the opposite side.

[0055] In the embodiment of the present invention, the top injection ports 4 of the three delivery chambers 1 are located on the same top surface 9, and the top surface 9 is an inclined surface or a curved surface that gradually tilts downward along the front and rear direction of the door body 100, so as to guide the water or detergent additives flowing to the top surface 9 to automatically flow into the drum under the action of gravity; preferably, the detergent additive delivery device is arranged on the door body 100 of the washing machine, and the top injection ports 4 of the three delivery chambers 1 are jointly located on the upper surface of the annular peripheral wall of the protrusion 7 of the door body 100, constituting the above-mentioned top surface 9, and the outer peripheral wall of the protrusion 7 is arranged to be a conical cylindrical surface with a radial dimension gradually narrowing toward the center from the outside to the inside of the drum, so that the water flow sprayed by the water inlet pipe 2 arranged above to the protrusion 7 can directly flow along the conical barrel surface into the drum, flush the side of the door body 100 facing the drum, avoid the clothes from entering the gap between the protrusion 7 of the door body 100 and the window pad 200, and flush the foam generated in the drum and attached to the door body 100.

[0056] In the embodiment of the present invention, the water spray outlets 8 of the two water inlet pipes 2 are both arranged above the higher side of the top surface 9, and are used to spray the water flow supplied by any one or a combination of the water inlet pipes 2 to the higher side of the top surface 9, so that the water flow can partially flow directly into the corresponding delivery cavity 1 through the injection port 4, and partially flow to the outer wall of the protrusion 7 of the door body 100, so as to achieve the effect of part of the water flow flowing along the outer wall of the protrusion 7 of the door body 100 to cover and flush the door body 100.

[0057] In the embodiment of the present invention, the projection of the water spray outlet 8 of the water inlet pipe 2 along the axis partially overlaps with the injection port 4 at the top of the delivery chamber 1 on the opposite side, so as to allow part of the incoming water flow of the water inlet pipe 2 to flow into the corresponding delivery chamber 1 through the injection port 4, and to spray part of the incoming water flow to the top surface 9 outside the injection port 4, thereby greatly improving the effect of the incoming water flow on flushing the outer wall of the protrusion 7 of the door body 100 and improving the self-cleaning effect of the incoming water flow on the door body 100; preferably, the vertical plane where the water spray outlet 8 of the water inlet pipe 2 is located is located on the highest side of the injection port 4 of the delivery chamber 1, so as to ensure that when the incoming water flow is sprayed to the outer wall of the protrusion 7, it automatically flows along the outer wall of the protrusion 7 toward the inside of the cylinder under the action of gravity, thereby guiding the incoming water flow to flow into the cylinder.

[0058] In the embodiment of the present invention, the axis of the water spray outlet 8 of the water inlet pipe 2 is inclined toward the high side of the top surface 9, and is used to spray the inlet water flow of the water inlet pipe 2 to the top surface 9 on the higher side of the injection port 4 of the opposite side delivery chamber 1. Part of the inlet water flow flows along the top surface 9 to the injection port 4 and enters the delivery chamber 1, and part of the inlet water flow flows along the top surface 9 to the surroundings to flush the outer wall and then flows downward, so that the inlet water flow can flush the outer wall of the door body 100 outside the injection port 4, and when the washing additive injected by the user from the injection port 4 into the delivery chamber 1 is splashed onto the outer wall of the protrusion 7 for self-cleaning flushing.

[0059] like Figures 1 to 3As shown, in the embodiment of the present invention, the water outlet end of the left water inlet pipe 21 is installed with a left nozzle 61, and the water outlet end of the right water inlet pipe 22 is installed with a right nozzle 62. Both nozzles 6 are detachably installed on the ring-mounted window pad 200; the left and right nozzles 6 are symmetrically arranged in the same shape. The left and right nozzles 6 can be any existing nozzle structure that can provide a water jet, for example: Figures 1 to 3 As shown, the nozzle 6 has a water channel with a reduced diameter of the water inlet pipe, the water inlet end of the water channel is connected to the water outlet end of the water inlet pipe 2, and the water outlet end of the water channel constitutes a water spray outlet 8, and the water flow flowing through the water inlet pipe 2 flows out from the water spray outlet 8; the outer wall of the nozzle 6 is provided with a clamping protrusion protruding radially outward, and the clamping protrusion is relatively engaged with the annular window pad 200, so that the nozzle 6 inserted on the window pad 200 is fixed in the axial direction by the clamping protrusion, so that the nozzle 6 and the window pad 200 are fixedly installed. Preferably, the radial size of the water channel inside the nozzle 6 is less than or equal to one-third of the diameter of the water inlet pipe 2, so as to further increase the injection flow rate of the water flow.
