Description

Technical Field

[0001] The invention belongs to a washing machine in the field of clothing cleaning, and in particular relates to a spraying and dispensing component for the washing machine for spraying and dispensing liquid into a washing machine barrel, and also relates to a dispensing device equipped with the spraying and dispensing component. Background Art

[0002] A washing machine is a frequently used household appliance. The washing machine is provided with an additive delivery device, which mainly includes a water box connected to the water inlet pipe of the washing machine and a liquid storage box contained in the water box. The liquid storage box is usually provided in a structure form that can be pulled out of the water box, so that the user can pull out the liquid storage box from the water box and add detergent, and / or softener, and / or disinfectant and other additives into the box.

[0003] The applicant previously proposed a new washing method in order to improve the washing effect and reduce the water consumption for washing: after the washing machine starts to take in water, the additives in the liquid storage box are sucked by a liquid pumping device and put into the water channel of the water box. The water in the water inlet pipe can first enter the water supply channel of the water box and mix with the additives to form a mixed liquid, and then be added to the inside of the washing machine to perform essence washing on the clothes.

[0004] However, in the prior art, most of the dispensing devices are used in drum-type washing machines, and the spray pipe used for essence washing is usually extended to the window pad of the washing machine. The fixing method is usually that the dispensing water channel of the dispensing device is connected to a water supply pipe, the water supply pipe extends to the window pad of the washing machine, and the water outlet end is connected to the spray head. The window pad is usually made of elastic material. During the use of the spray pipe, especially when water is just started to be sprayed, the reaction force of the water will push the spray head to compress the window pad, and then the spray head will begin to shake, which can easily cause the spray pipe to fall off the water supply pipe and damage the spray head.

[0005] The applicant has specially filed this application in order to adapt the dispensing device capable of performing essence washing to other types of washing machines such as pulsator washing machines.

[0006] At the same time, the water source of the existing washing machine has unstable water pressure and the water flow may change too fast or too slowly, which may cause the water shape of the water flow from the feeding device to the washing machine barrel to change, and it is impossible to achieve the effect of covering the clothes in the barrel for essence washing. Therefore, providing a feeding device for stabilizing the pressure of the water flow has become a technical problem that technicians in this field need to solve urgently.

DETAILED DESCRIPTION

[0041] 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.

[0043] 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.

[0044] In the embodiment of the present invention, the additive is a common consumable used for cleaning clothes, such as a detergent, a rinse agent, a softener and / or a disinfectant.

[0045] like Figures 1 to 7 In the embodiment of the present invention, a spray delivery assembly 9 for a washing machine is introduced, including a spray chamber 91, a water inlet 93 is provided on one side, and a plurality of spray holes 92 for spraying water outward on the other side; a pressure regulating valve structure, at least a valve core 94 is provided in the spray chamber 91, and the valve core 94 is driven to move by the water pressure of the water flowing into the spray chamber 91 through the water inlet 93, so as to switch at least part of the spray holes 92 on and off at different water pressures.

[0046] By installing a pressure regulating valve in the spray chamber, at least part of the spray holes of the spray chamber can be automatically opened as the inlet water pressure increases, so that the number of spray holes is increased when the inlet water pressure is too high, and the partial pressure of the inlet water flow with a larger water pressure is automatically adjusted to ensure that the outlet water pressure of the spray holes of the spray chamber remains constant, so that the outlet water shape of the water flow ejected from the spray holes will not change due to changes in the inlet water pressure, thereby achieving significant technical progress in automatically regulating the pressure of the ejected water flow and improving the stability of the ejected water flow.

[0047] like Figures 1 to 7 As shown, in the embodiment of the present invention, one side of the spray chamber 91 is a vertically extending water outlet side, and the water outlet side has a plurality of spray holes 92 at different heights; the pressure regulating valve structure includes a valve core 94, which is horizontally extended and arranged in the spray chamber 91, and a water inlet 93 is connected to a portion of the spray chamber 91 below the valve core 94; an elastic member, the upper and lower ends of which are respectively connected to the valve core 94 and the inner wall of the spray chamber 91, for maintaining the valve core 94 in an initial position, correspondingly closing at least part of the spray holes 92 at a corresponding height; and when the water pressure of the water inlet of the spray chamber 91 increases, the elastic force of the elastic member is overcome, the valve core 94 is pushed to move up and down, and at least part of the spray holes 92 arranged at the corresponding height is opened.

[0048] When no water enters the spray chamber 91, the valve core 94 of the pressure regulating valve structure is in the lowest initial position under the action of gravity. At this time, the valve core 94 corresponds to closing at least part of the spray hole 92 at the height; and after the water flow flows into the water inlet 93 and the water pressure of the water flow reaches the set value, the water pressure of the water inlet will push the valve core 94 to overcome the elastic force of the elastic member and move upward. After the upward movement, the valve core 94 will adjust the corresponding spray hole 92 set at the rising height to an open state, so that the number of open spray holes 92 connected to the spray chamber 91 increases, so that the water pressure of the spray delivery component 9 will not change too much with the change of the water pressure, and the water shape of the water outlet will remain stable, thereby not changing the coverage range of the spray delivery water flow on the washing machine barrel, effectively improving the spraying uniformity of the detergent additive mixture sprayed by the spray delivery component into the barrel, so as to achieve the washing effect of improving the detergent additive mixture for essence washing of the clothes in the barrel.

[0049] Preferably, when the valve core 94 of the pressure regulating valve structure is in the lowest initial position under the action of gravity, at least the lowest part of the spray holes 92 is in an open state, and the water flow in the spray chamber 91 can be ejected outward from the lowest part of the spray holes 92, so that the lowest spray holes 92 are in a normally open state, ensuring that there is no liquid residue in the spray chamber 91. Preferably, a support rib protruding upward is provided on the bottom wall of the spray chamber 91, and the upper end of the support rib is in supporting contact with the lower end of the valve core 94, so as to support the valve core 94 in the initial position, and at least the lower spray holes 921 are in a normally open state.

[0050] like Figures 1 to 7 As shown, in the embodiment of the present invention, the water outlet side of the spray chamber 91 is provided with at least three rows of spray holes 92 at different heights, namely, a lower spray hole 921, a middle spray hole 922 and an upper spray hole 923; the upper, middle and lower three parts of the spray holes 92 respectively have a plurality of spray holes 92 arranged at intervals, arranged in sequence along the circumferential direction and at the same height, and the upper, middle and lower three parts of the spray holes 92 are arranged in an interlaced manner, so that the center of the middle spray hole 922 is located between two adjacent lower spray holes 921 and between two adjacent upper spray holes 923, so that the three parts of the spray holes 92 are arranged in an interlaced matrix, so that the spray water flows of each part of the spray holes 92 are sprayed in an interlaced manner, thereby effectively improving the distribution uniformity of the spray water flows.

[0051] When the water pressure in the spray chamber 91 does not reach the first set value, the valve core 94 of the pressure regulating valve structure is in the initial position, and the lower spray hole 921 is opened, so that the water flow with a relatively small water pressure can be sprayed outward from the lower spray hole 921;

[0052] When the water pressure in the spray chamber 91 reaches a first set value, the valve core 94 of the pressure regulating valve structure moves upward to a first set height position, and the middle spray hole 922 and the lower spray hole 921 are opened, so that the water flow with a medium water pressure can be sprayed outward from the lower spray hole 921 and the middle spray hole 922;

[0053] When the water pressure in the spray chamber 91 reaches the second set value, the valve core 94 of the pressure regulating valve structure moves upward to the second set height position, and the upper spray hole 923, the middle spray hole 922 and the lower spray hole 921 are all opened, so that the water flow with a larger water pressure can be sprayed outward from the lower spray hole 921, the middle spray hole 922 and the upper spray hole 923.

[0054] like Figures 1 to 7 As shown, in the embodiment of the present invention, the elastic member is a spring 95 extending downward from the top wall of the spray chamber 91, the upper end of the spring 95 is connected to the top wall of the spray chamber 91, and the lower end is connected to the horizontally arranged valve core 94; preferably, a spring 95 is respectively connected to the opposite sides and the center of the valve core 94, and the three springs 95 are symmetrically arranged relative to the center of the valve core 94; further preferably, the upper end surface of the valve core 94 is provided with an assembly column 98 protruding upward, and there is a height difference between the upper end of the assembly column 98 and the top wall of the spray chamber 91, and the height difference is greater than the height difference between the second set height and the initial position, the lower part of the spring 95 is correspondingly sleeved on the outer periphery of the assembly column 98, and the lower end of the spring 95 is fixed to the valve core 94, so that the assembly column 98 protruding vertically upward can guide the spring 95 and avoid excessive deflection of the spring 95 during the up and down movement of the valve core 94.

[0055] In an embodiment of the present invention, a positioning column 96 protruding and extending downward is provided on the lower side of the valve core 94, and the positioning column 96 is correspondingly inserted into a positioning groove 960 correspondingly opened on the bottom wall of the spray chamber 91, and the depth of the positioning groove 960 is greater than the height difference between the second set height and the initial position, and the upper and lower heights of the positioning column 96 are greater than or equal to the height difference between the second set height and the initial position; preferably, a positioning column 96 is respectively provided on the opposite sides and the center of the valve core 94, which further effectively ensures that the valve core 94 will not deviate left and right during the up and down movement, and prevents the valve core 94 from moving horizontally to affect the accuracy of opening and closing control of the spray hole 92 at the corresponding height.

[0056] In an embodiment of the present invention, a side wall of the valve core 94 facing the water outlet side of the spray chamber 91 is a sealing wall 941, and the sealing wall 941 is arranged in the same shape as the water outlet side of the spray chamber 91 and is in close contact with each other, and the spray hole 92 at the close contact point and the upper side is closed accordingly; preferably, the upper and lower heights of the sealing wall 941 of the valve core 94 are greater than the sum of the heights of the middle spray hole 922 and the upper spray hole 923, so that when the valve core 94 is in the initial position, the middle spray hole 922 and the upper spray hole 923 can be effectively closed at the same time, effectively preventing the incoming water from spraying out from the unopened, higher spray hole 92. Further preferably, in order to improve the sealing performance of the valve core when it closes the spray hole, a sealing gasket made of elastic material such as rubber can be installed on the sealing wall of the valve core. The sealing gasket is located between the sealing wall of the valve core and the water outlet side of the spray chamber, so that the valve core in close contact can utilize the elastic deformation of the sealing gasket to form an effective extrusion deformation and reliably close the spray hole.

[0057] In an embodiment of the present invention, a water guide portion 97 is provided at the water inlet 93 of the valve core 94 facing the spray chamber 91, which is used to guide the inlet water flow flowing into the water inlet 93 to flow to the spray chamber 91 portion below the valve core 94, so that the inlet water flow can only flow out from the spray hole 92 below the valve core 94; preferably, the water guide portion 97 is an open groove 970 with an opening 971 opened toward the water inlet 93, and the open groove 970 also has an opening 972 opened downward; the lower end of the water inlet 93 of the spray chamber 91 is arranged flush with the bottom wall of the spray chamber 91, and the upper end is lower than the opening 971 of the open groove 970, so that the inlet water flow flowing in from the water inlet 93 enters the water guide portion 97 and flows to the spray chamber 91 portion on the lower side of the valve core 94.

[0058] Further preferably, in order to ensure that the water flow from the water inlet 93 into the spray chamber 91 can all flow to the bottom of the valve core 94, the following settings are made: when the valve core 94 is in the initial position, the water guide 97 provided on the valve core 94 is higher than the water inlet 93, so that the upper edge of the open 971 of the open slot 970 of the water guide 97 is higher than the water inlet 93, so as to ensure that the water flow from the water inlet 93 into the spray chamber 91 all enters the open slot 970 and below, and flows from the opening 972 on the lower side of the open slot 970 to the lower part of the valve core 94 in the spray chamber 91. At the same time, the size of the open slot 971 of the open slot 970 in the radial direction is greater than or equal to the water inlet 93, so as to further ensure that the water flow from the water inlet 93 can be guided by the open slot 970 and flow to the bottom of the valve core 94. In addition, a protruding retaining rib 973 extending radially outward is provided at the open groove 970, the protruding retaining rib 973 abuts against the outer peripheral wall of the spray chamber 91, is located at the periphery of the water inlet 93 and at least covers the upper part of the water inlet 93, so as to ensure that the water flow flowing in from the water inlet 93 is guided by the protruding retaining rib 973 and flows to the lower part of the valve core 94.

[0059] In the embodiment of the present invention, the open groove 970 of the water guide 97 at least partially overlaps with the height of the water inlet 93, so that the water flow flowing in from the water inlet 93 directly enters the open groove 970 and impacts the bottom wall of the open groove 970. The impact force can push the valve core 94 to move upward, thereby achieving the effect that the water flow with different water pressures drives the valve core 94 to automatically move upward; preferably, in order to improve the water flow impact effect and guide the smoothness of the water flow, the upper corner of the groove bottom of the open groove 970 is provided with an arc surface to guide the water flow to flow downward and avoid the formation of vortexes in the open groove 970 to hinder the water flow. Further preferably, when the valve core 94 is in the initial position, the first set height position, and the second set height position, at least part of the openness of the open groove 970 overlaps with the height of the water inlet 93 to ensure that at least part of the water flow can smoothly enter the open groove 970 and the water pressure of the water can achieve the effect of moving and adjusting the valve core 94.

[0060] like Figures 1 to 7 As shown, in the embodiment of the present invention, the spray chamber 91 is horizontally fan-shaped, the inner peripheral side of the fan-shaped spray chamber 91 is the water outlet side 911, and a plurality of spray holes 92 are arranged, and the outer peripheral side is the water inlet side 912, and a water inlet 93 is provided; the water inlet 93 is located at the center of the outer peripheral side of the fan-shaped spray chamber 91 to ensure that the incoming water flow can enter the chamber from the middle and improve the water pressure balance at various locations in the chamber. At the same time, the bottom wall of the fan-shaped spray chamber 91 is provided with a plurality of water-distributing ribs 99, and each water-distributing rib 99 extends from the water inlet 93 on the outer peripheral side of the fan-shaped spray chamber 91 along different radial directions to each spray hole 92 on the inner peripheral side; each radially divergently extending water-distributing rib 99 is arranged at intervals, and the gaps between each adjacent water-distributing rib 99 constitute a water-distributing flow channel, and the water inlet end of each water-distributing flow channel converges at the water inlet 93, and the water outlet end is arranged in sequence at each part of the inner peripheral side of the fan; preferably, the water outlet end of a water-distributing flow channel is connected to at least one spray hole 92; further preferably, each radially divergently extending water-distributing rib 99 is arranged in sequence at equal intervals.

[0061] The inner circumference of the fan-shaped spray chamber 91 is in an arc shape, and three rows of spray holes 92 are arranged on the inner circumference of the arc shape, namely, upper, middle and lower rows. The upper, middle and lower rows of spray holes 92 respectively have a plurality of upper spray holes 923, middle spray holes 922 and lower spray holes 921 arranged at intervals along the circumferential direction; each row of spray holes 92 respectively has a plurality of spray holes 92 arranged at intervals and arranged in sequence along the arc shape of the inner circumference. The upper, middle and lower rows of spray holes 92 are arranged in an alternating manner, so that the center of the middle spray hole 922 is located between two adjacent lower spray holes 921 and between two adjacent upper spray holes 923, so that the multiple rows of spray holes 92 are arranged in an alternating matrix, so that the spray water flows of each row of spray holes 92 are sprayed in an alternating manner, thereby improving the distribution uniformity of the spray water flows.
