Description

Clothes treating agent throwing device and washing machine

Technical Field

The invention belongs to the technical field of clothes treatment equipment, and particularly relates to a clothes treatment agent throwing device and a washing machine.

Background

In the prior art, a washing machine generally puts in a clothes treating agent such as a detergent, a softener and the like along with water inflow in the water inflow process, and the clothes treating agent is directly flushed into an inner cylinder of the washing machine by the water inflow. The feeding mode is unfavorable for the thorough mixing of the clothes treating agent and the water flow, so that the clothes treating agent cannot be fully dissolved when being fed into the inner cylinder, and is quickly deposited to the bottom in the inner cylinder. Especially, in the initial stage of washing, the detergent is not sufficiently dissolved in water, and the washing is started by washing the laundry with water without the addition of the detergent solution, resulting in poor washing effect. After a period of time from the start of washing, most of the detergent can be uniformly distributed in the water along with the rotation of the inner cylinder, so that the detergent is fully contacted with the clothes to remove stains on the clothes. In order to ensure the washing effect, the washing time is required to be prolonged, the whole washing time is prolonged, the energy consumption is increased, and the abrasion degree of clothes is increased.

On the other hand, as the clothes treating agent is not fully mixed with water flow and enters the inner cylinder, part of the solution with higher concentration of the clothes treating agent can be directly absorbed by clothes in the inner cylinder, which is more unfavorable for the subsequent dissolving process of the clothes treating agent. In the water inflow process, if the amount of the laundry in the inner tub is large, it may be impossible to wet the entire laundry, and even a part of the laundry is not completely wetted after several minutes from the start of washing, and thus cannot be sufficiently contacted with the laundry treating agent. The uneven action of the laundry treatment agent on the laundry inside the drum results in a lower efficiency of use of the laundry treatment agent, resulting in wastage of the laundry treatment agent.

In view of this, the present invention has been made.

Example 1

The embodiment provides a clothes treating agent throwing device and a washing machine comprising the same. The laundry treatment agents include, but are not limited to, detergents, softeners, disinfectants, and the like.

As shown in fig. 1 to 7, the delivery device in this embodiment includes an adding unit 300, a mixing unit, and a spraying unit that are sequentially connected.

Wherein the adding unit 300 includes a water inlet 310 for water inlet and a liquid outlet 320. The adding unit 300 is connected with a liquid storage cavity for storing the laundry treating agent, an external water source enters the adding unit 300 from the water inlet 310, the adding unit 300 adds the laundry treating agent into the water flow, and then the water flow containing the laundry treating agent is sent out through the liquid outlet 320.

The mixing unit comprises a mixing tank 100, and a liquid inlet 101 and a liquid outlet 102 are arranged on the mixing tank 100. The liquid inlet 101 communicates with the liquid outlet 320 of the adding unit 300, and the laundry treating agent and water flowing out of the liquid outlet 320 enter the mixing tank 100 through the liquid inlet 101, and are mixed inside the mixing tank 100. The well mixed liquid is discharged through the outlet 102 of the mixing tank 100.

The spray unit includes a spray pipe 410 connected to the liquid outlet 102 of the mixing tank 100, and a spray head 420 disposed at the outlet end of the spray pipe 410, and the liquid fully mixed in the mixing tank 100 is sprayed out through the spray head 420, so that a larger coverage area of the laundry treatment agent can be realized.

As shown in fig. 8, the washing machine of the present embodiment includes an inner tub 510 and an outer tub 520 coaxially disposed, and a spray head 420 is installed at a tub opening of the inner tub 510 to spray a liquid, in which laundry treating agent and water are sufficiently mixed, into the inner tub 510. As shown in fig. 7, the nozzle of the nozzle 420 has a shape with a width at the upper end larger than that at the lower end, so that the spraying distance of the liquid sprayed out of the nozzle 420 can be increased, and particularly, the difference of the spraying distances of the liquid at the upper end and the lower end of the nozzle 420 can be increased, which is beneficial to increasing the spraying coverage area, enabling the load in the drum to be fully contacted with the laundry treatment agent, and improving the washing effect.

The washing machine further comprises a water inlet valve 531, the water inlet valve 531 is connected with the adding unit 300 through a water inlet pipe 532, when the water inlet valve 531 is opened, an external water source enters the adding unit 300 through the water inlet valve 531 and the water inlet pipe 532, the adding unit 300 adds the laundry treating agent into water, then enters the mixing tank 100 for full mixing, and finally is sprayed out from the spray head 420 through the spray pipe 410, so that the laundry treating agent is put into the inner barrel 510.

The washer inlet water may also pass through inlet valve 531 and inlet pipe 532 and eventually be sprayed into inner tub 510 by spray head 420. The water inlet pipe may be separately provided to directly communicate the water inlet valve 531 with the inner cylinder 510 or the outer cylinder 520, thereby realizing the water inlet function of the washing machine.

The washing machine of the present embodiment further includes a driving motor 541 for driving the inner tub 510 to rotate. Specifically, the bottom of the inner cylinder 510 is connected to an inner cylinder shaft 511 passing through the bottom of the outer cylinder 520, a driving motor 541 is disposed below the outer cylinder 520, and an output shaft of the driving motor 541 is in driving connection with the inner cylinder shaft 511 through a driving belt 542, so as to drive the inner cylinder 510.

It should be noted that the throwing device in this embodiment may also be applied to a direct-drive drum washing machine.

As shown in fig. 2 to 6, in a further aspect of the present embodiment, in order to achieve sufficient mixing of the laundry treating agent and water in the mixing tank 100, an auxiliary mixer 200 having a certain liquid receiving amount is provided inside the mixing tank 100. The liquid entering through the liquid inlet 101 impacts the liquid received in the auxiliary mixer 200, the laundry treating agent in the liquid is mixed with water under the impact, overflows from the auxiliary mixer 200, and overflows liquid is discharged through the liquid outlet 102 of the mixing tank 100. The flow path of the liquid into and out of the mixing tank 100 is specifically shown by the arrows in fig. 4.

Specifically, the auxiliary mixer 200 includes a receiving part 210 disposed below the liquid inlet 101, an upper side surface of the receiving part 210 is recessed downward to form a mixing space with an upper side opened, and the liquid outlet 102 of the mixing tank 100 is lower than the upper side opening of the mixing space. The liquid entering the mixing tank 100 is received in the mixing space, and the laundry treating agent and water therein are mixed under the impact of the subsequent liquid entering, and overflows through the opening at the upper side of the mixing space, and is discharged through the liquid outlet 102.

In the above-described aspect, the laundry treating agent and water are introduced into the mixing tank 100 through the liquid inlet 101, and the introduced liquid impinges on the upper surface of the receptacle 210 at the beginning. Since the upper surface of the receiving portion 210 is concave downward to form a mixing space, the entered liquid does not directly bypass the receiving portion 210 to the liquid outlet 102, but is temporarily stored in the mixing space. Only when the subsequent liquid (which may be a mixed solution of the laundry treating agent and water or the water inlet without the laundry treating agent) continues to enter the mixing tank 100, the liquid level in the mixing space rises, and the liquid overflows from the opening at the upper side of the mixing space and flows downwards, so that the liquid is discharged from the liquid outlet 102 out of the mixing tank 100. The liquid entering the mixing tank 100 falls onto the liquid level in the mixing space, and continuously impacts the existing liquid in the mixing space, so that the laundry treating agent and water in the mixing space can be overflowed after being fully mixed, and the overflowed laundry treating agent or water is not pure.

By providing the auxiliary mixer 200 with a certain liquid receiving amount in the mixing tank 100, the auxiliary mixer 200 can receive a certain amount of liquid through the receiving portion 210, and the purpose of fully mixing the laundry treating agent and the water is achieved by impacting the liquid in the receiving portion 210 by the subsequently entered liquid. This allows for more thorough mixing and dissolution of the laundry treating agent before it exits the mixing tank 100, and thus allows for more thorough contact of the laundry treating agent with the load being washed at an early stage of the washing/rinsing phase. Especially for the detergent put in the washing stage of the washing machine, the utilization efficiency of the detergent in the initial washing stage can be effectively improved, the washing ratio of clothes is further improved, the washing time of the washing machine is shortened, and the effect of reducing energy consumption is achieved.

In a preferred version of this embodiment, the liquid inlet 101 is provided at the top of the mixing tank 100. The vertical distance between the liquid inlet 101 and the receiving portion 210 can be increased as much as possible under the condition that the shape and the size of the mixing tank 100 are fixed, so that the impact force of the liquid on the receiving portion 210 is improved, and a more sufficient mixing effect is realized.

The liquid outlet 102 is provided at the bottom of the mixing tank 100, preferably at the lowest position of the mixing tank 100, so that the liquid overflowed from the upper side of the receiving part 210 more easily flows to the liquid outlet 102 and smoothly exits the mixing tank 100.

In a further aspect of this embodiment, the receiving portion 210 is a bowl-shaped structure with a middle portion lower than the periphery, and the liquid falls into the bowl-shaped structure through the liquid inlet 101, and overflows from the bowl opening of the bowl-shaped structure.

Preferably, the downward projection of the liquid inlet 101 covers the lowest position of the bowl-shaped structure, further increasing the falling distance when the liquid impacts on the receiving portion 210 after entering through the liquid inlet 101, and ensuring the mixing effect.

The outer periphery of the bowl opening of the bowl-shaped structure of the receiving portion 210 is spaced from the inner wall of the mixing tank 100, and the liquid overflowing the bowl-shaped structure flows to the liquid outlet 102 through the space.

Further, a limiting part 211 protruding towards the outer periphery is arranged at the bowl mouth of the bowl-shaped structure of the receiving part 210, the limiting part 211 is propped against the inner wall of the mixing tank 100, and the limiting part 211 forms a space for passing overflow liquid along two sides of the bowl mouth in the circumferential direction.

By providing the limiting portion 211 at the bowl opening, the relative position of the receiving portion 210 in the mixing tank 100 can be limited, so that a space enough for overflow liquid to flow downwards is ensured at the periphery of the bowl opening of the receiving portion 210, and the overflow liquid after mixing can smoothly flow below the receiving portion 210 and be discharged out of the mixing tank 100 through the liquid outlet 102.

Preferably, a plurality of limiting parts 211 are arranged along the circumferential direction of the bowl mouth of the bearing part 210, and a space for passing overflow liquid is formed between two adjacent limiting parts 211.

In the specific scheme of this embodiment, four limiting portions 211 are disposed on the receiving portion 210, and the four limiting portions 211 are uniformly distributed along the circumferential direction of the bowl mouth. The upper bowl mouth of the receiving portion 210 is circular, and a deviation angle of 90 degrees is formed between two adjacent limiting portions 211. The cross section of the mixing tank 100 perpendicular to the axial direction of the liquid inlet 101 is also circular, so that the receiving part 210 can be stably limited in the center of the mixing tank 100 through four limiting parts 211.

In a further aspect of this embodiment, the receiving portion 210 is provided with a drain hole 212 that communicates with the space on the upper and lower sides of the receiving portion 210. Drain hole 212 is preferably disposed at the lowest position of receptacle 210.

In the above-mentioned scheme, the diameter of the drain hole 212 is far smaller than the caliber of the liquid inlet 101, and in the process that liquid continuously enters the mixing tank 100 through the liquid inlet 101, the amount of liquid leaked out of the receiving portion 210 through the drain hole 212 is negligible compared with the amount of liquid overflowed from the opening of the receiving portion 210, so that the mixing effect of the laundry treatment agent and water is not obviously affected. When the liquid feeding to the mixing tank 100 is stopped, the liquid level in the receiving part 210 does not rise any more, and the liquid remaining in the receiving part 210 can be slowly discharged out of the receiving part 210 through the drain hole 212, so that the problem of laundry treatment agent and water remaining in the receiving part 210 is prevented.

In this embodiment, the auxiliary mixer 200 further includes a support portion connected to the receiving portion 210, for supporting the receiving portion 210 at a certain height within the mixing tank 100. The supporting part plays a supporting role below the bearing part 210, so that the auxiliary mixer 200 is ensured to be stably fixed inside the mixing tank 100, and particularly, the bearing part 210 can be prevented from being impacted by the mixed solution to move downwards and even being impacted to turn over, so that the mixing effect of the clothes treating agent and water is influenced.

Further, a plurality of raised mounting portions 103 are provided on the inner wall of the mixing tank 100, and the support portion includes a plurality of support bars 220. The upper end of the support rod 220 is connected to the receiving portion 210, and the lower end of the support rod 220 abuts against the upper surface of the mounting portion 103.

Specifically, three mounting portions 103 are uniformly provided on the inner wall of the mixing tank 100 of the present embodiment in the circumferential direction. The three support rods 220 are correspondingly arranged, the upper ends of the support rods 220 are connected to the outer surface of the bottom area of the bearing part 210, and extend downwards in an inclined manner in a direction gradually approaching the inner wall of the mixing tank 100 until the lower ends are supported on the mounting part 103, so that the structure is more stable.

In this embodiment, the mixing tank 100 is formed by assembling an upper housing 110 and a lower housing 120 that are separately arranged, the liquid inlet 101 is arranged at the top of the upper housing 110, and the liquid outlet 102 is arranged at the bottom of the lower housing 120. The mounting part 103 is provided on the inner wall of the lower housing 120, the auxiliary mixer 200 is placed inside the lower housing 120, supported above the mounting part 103 by the support rod 220, and then the upper housing 110 is fastened with the lower housing 120, and the limit part 211 of the upper open outer periphery of the receiving part 210 is abutted against the inner wall of the upper housing 110, thereby stably fixing the auxiliary mixer 200 inside the mixing tank 100.

The mixing tank 100 is centrally symmetric about the vertical direction, the axes of the liquid inlet 101 and the liquid outlet 102 are coincident with the symmetry axis of the mixing tank 100, the receiving part 210 of the auxiliary mixer 200 is also centrally symmetric about the symmetry axis, and the drain hole 212 on the receiving part 210 is located on the symmetry axis.

The mixing tank 100 of the present embodiment is generally ellipsoidal, and it is understood that the mixing tank may be configured in other shapes, such as spherical, square, etc., and the same effect may be achieved by only correspondingly adjusting the shape of the auxiliary mixer.

In this embodiment, a mixing tank 100 for mixing a laundry treatment agent and water is provided in a laundry treatment agent dispensing device, an auxiliary mixer 200 having a certain liquid receiving amount is provided in the mixing tank 100, and liquid entering the mixing tank 100 is received in a receiving portion 210 of the auxiliary mixer 200, and the liquid in the receiving portion 210 is impacted by the subsequent liquid entering, so that the laundry treatment agent and water are fully mixed. The dispensing device further comprises a spraying unit provided with a spray head 420, and the laundry treating agent solution obtained after full mixing is sprayed out of the spray head 420, so that on one hand, the uniformity of mixing can be further improved under the pressure effect when the solution is sprayed out, and on the other hand, the coverage area when the laundry treating agent solution falls into the inner barrel 510 of the washing machine can be increased, so that the laundry treating agent is fully contacted with the load in the barrel, and the washing effect can be improved.

Example two

The present embodiment provides a control method of the washing machine according to the above embodiment, which is used in a laundry treatment agent delivery process.

As shown in fig. 9, the control method includes the steps of:

s1, controlling the inner cylinder to rotate at a first set rotating speed, so that the load in the cylinder is attached to the inner wall of the inner cylinder under the action of centrifugal force;

s2, adding a clothes treating agent into water inflow of the washing machine, mixing through a mixing unit, and putting the mixed clothes treating agent solution on a load surface attached to the inner wall of the inner cylinder.

Specifically, as shown in fig. 1 and 8, after receiving an instruction to start a washing program, the washing machine starts to perform the laundry treatment agent delivery according to the control method.

In step S1, the computer board of the washing machine controls the start-up driving motor 541 to drive the inner cylinder 510 to rotate continuously at the first set rotational speed. The first set rotational speed is higher, for example, 90-100rpm, so that the load in the inner cylinder 510 is acted by centrifugal force, and the inner side of the side wall of the inner cylinder 510 can be spread out nearly uniformly, thereby increasing the surface area of the load, and facilitating rapid wetting of the load when the inflow water enters the inner cylinder 510.

In step S2, the inlet valve 531 is controlled to be opened, and the inflow water flows to the adding unit 300 through the inlet valve 531 and the inlet pipe 532. The inflow water flows through the adding unit 300, the laundry treatment agent is added into the inflow water flow through the adding unit 300, the inflow water flow carries the laundry treatment agent into the mixing tank 100, and the laundry treatment agent solution is obtained after the uniform mixing. The laundry treating agent solution flows through the shower pipe 410 and is finally sprayed into the inner cylinder 510 by the spray head 420, so that a coverage area with a certain area is formed in the inner cylinder 510, and the effect that the laundry treating agent solution is directly sprayed on the load surface is achieved. At the same time, the in-drum load continuously passes through the coverage area as the inner drum 510 rotates, thereby enabling the load to uniformly contact the laundry treating agent solution to be wetted.

Step S1 and step S2 may be simultaneously started, that is, the washing machine receives an instruction to start a washing program, and then controls the driving motor 541 to start, and simultaneously opens the water inlet valve 531.

The spray head 420 has a spray nozzle as shown in fig. 7, and is installed at the nozzle of the inner drum 510, and the laundry treating agent solution is sprayed into the drum from the nozzle of the inner drum 510, forming a strip-shaped coverage area on the wall of the inner drum 510 nearly parallel to the axis of the inner drum 510. The strip-shaped covering area extends from the nozzle to the bottom of the drum, so that the load attached to the inner side of the drum wall of the inner drum 510 can be in direct contact with the sprayed laundry treatment agent solution along with the rotation process of the inner drum 510.

The furthest end of the spray of the laundry treatment agent solution may be sprayed onto the bottom of the inner drum 510, thereby also forming a sized coverage area on the bottom of the inner drum 510, ensuring that the load applied to the bottom of the inner drum 510 may also be wetted by the laundry treatment agent solution.

The nozzle structure of the nozzle 420 is designed to be matched with the inner cylinder 510 in size, so that the covering area of the clothes treating agent solution on the bottom of the inner cylinder 510 extends from the periphery of the bottom to the central position of the bottom, for example, a strip-shaped covering area extending upwards from the lowest position of the bottom to the center of the bottom is formed on the bottom of the inner cylinder 510. In this way, during rotation of the inner tub 510, the entire bottom of the inner tub 510 may pass through the covering area of the laundry treating agent solution, thereby ensuring that the laundry treating agent is sufficiently contacted by the load in the tub, and achieving uniform spraying of the laundry treating agent solution on the load surface.

It should be noted that, the installation position of the spray head may be changed, for example, the spray head may be installed at any position around the nozzle, and the direction and structure of the spray nozzle may be adjusted correspondingly, so that the sprayed laundry treatment agent solution may cover the whole range from the nozzle to the bottom and cover a certain area extending from the periphery to the center of the bottom.

In a further aspect of this embodiment, step S2 further includes step S3: the washing machine continues to feed water, the addition of the clothes treating agent is stopped, and the inner cylinder keeps the first set rotating speed to rotate continuously.

When the laundry treating agent added in step S2 reaches a certain amount, the adding unit 300 stops the addition of the laundry treating agent while the water inlet valve 531 is kept opened, and water is continuously sprayed to the inner cylinder 510 through the water inlet pipe 532, the adding unit 300, the mixing tank 100, the shower 410 and the shower head 420. On the one hand, the laundry treating agent remaining in the mixing tank 100 can be carried out, ensuring that the laundry treating agent added in step S2 sufficiently enters the inner tub 510. On the other hand, the total amount of the liquid sprayed into the inner cylinder 510 in step S2 is limited, when the load in the cylinder is large, the side of the load near the inner wall of the inner cylinder 510 may not be wetted yet, and the water content of the load can be further increased by continuously spraying water into the inner cylinder 510, so that the load in the cylinder is fully wetted before the washing/rinsing process is started.

In this embodiment, step S3 further includes step S4: stopping water inflow, controlling the rotating speed of the inner cylinder to be reduced to a second set rotating speed and continuously rotating.

In step S4, the water inlet valve 531 is closed, and the driving motor 541 is controlled to reduce the output rotation speed, so as to drive the inner cylinder 510 to continuously rotate at the second set rotation speed. The second set rotation speed may be 30-40rpm, the centrifugal force applied to the load is greatly reduced, and the load is not attached to the inner wall of the inner cylinder 510 any more, but is lifted to a certain height along with the rotation of the inner cylinder 510 and then falls down, so that the load in the cylinder turns over in the inner cylinder 510 along with the rotation of the inner cylinder 510.

In this stage, the inner drum 510 rotates at a low speed to turn the load in the drum over, so that the load has a similar effect to hand washing and kneading, and the laundry treating agent solution in the drum is stirred, and the injected laundry treating agent solution can be more uniformly attached to the load.

In one implementation manner of this embodiment, step S3 is performed until the first preset duration is reached, and step S4 is performed. The washing machine can automatically determine the value of the first preset duration according to the load in the drum, so that the load in the drum can be fully wetted.

Another implementation of this embodiment is a washing machine that is provided with a flow sensor for detecting the amount of water entering the inner drum 510 through the inlet pipe 532. The washing machine performs step S4 when the continuous inflow detected during the execution of step S3 reaches the preset inflow. The specific value of the preset water inflow can be automatically determined by the washing machine according to the load in the drum, so that the load in the drum is fully wetted.

In a further aspect of this embodiment, step S4 is continuously performed for a second preset duration, and returns to step S1.

Specifically, step S4 is continuously executed for a second preset duration, the washing machine judges whether the execution frequency N of step S2 reaches the preset frequency N, if yes, the releasing process is ended, otherwise, the step S1 is returned to.

In the above scheme, the washing machine inputs the laundry treating agent into the inner tub 510 several times, and completes the laundry treating agent input process. After a certain amount of laundry treating agent is added each time, a certain amount of water is added to the inner cylinder 510, and then the added laundry treating agent solution and the load are fully and uniformly mixed by reducing the rotation speed of the inner cylinder 510. Because the amount of the laundry treatment agent put in each time is relatively smaller, compared with the mode of putting a large amount of laundry treatment agent at one time, the laundry treatment agent is more beneficial to the uniform and full contact between the load in the drum and the laundry treatment agent, thereby further improving the laundry effect.

In a specific solution of this embodiment, before the first execution of step S1, step S0 is further included: determining the total amount of laundry treatment agent to be added X according to the in-drum load information and/or the laundry program information, and adding the laundry treatment agent to the laundry treatment agent in a single amount of addition X in step S2 ₀ And calculating the preset times N by the total amount X of the throwing.

Further, the washing machine determines the single-administration amount X according to in-drum load information and/or washing program information ₀ Is a value of (a).

The in-cartridge loading information includes, but is not limited to, loading, color information, texture information, degree of soiling, and the like. The in-cylinder load information can be determined by receiving the setting operation information of a user, and an identification device can be arranged on the washing machine to identify the in-cylinder load so as to acquire related information.

The laundry program information includes at least a program type and/or a program parameter. The washing program information can be determined by receiving the setting operation of a user on the washing program, and the washing program can be automatically generated according to the obtained in-cylinder load information, so that the washing program information is determined.

In another aspect of this embodiment, the washing machine does not preset the total amount of laundry treatment agent to be put in before starting the putting in, but detects relevant parameters during the putting in process to determine whether to continue the putting in process.

Specifically, step S4 is continuously executed for a second preset time period, the washing machine detects the turbidity value of the water in the drum, if the detected turbidity value reaches the preset turbidity value, the throwing process is ended, otherwise, the step S1 is returned to.

The scheme is mainly suitable for the process of putting the detergent. As the amount of detergent added to the inner tub 510 increases, the turbidity value of the tub water gradually decreases. When the current turbidity value of the water in the barrel is detected to be reduced to the preset turbidity value or lower, the current total detergent throwing amount is well adapted to the load quantity in the barrel and the pollution degree of the load. At this time, the putting process is finished, the washing machine continues to feed water to the set washing water level for washing, the washing ratio meeting the requirements of users can be obtained, and meanwhile, the situation that waste is caused by excessive putting of the washing agent or washing agent residues exist after load washing is finished due to insufficient removal of the washing agent in the rinsing process is avoided.

The control method of the washing machine in the embodiment is used for the process of putting the clothes treating agent, so that the clothes treating agent solution mixed with water uniformly is sprayed on the surface of the load in the drum uniformly, and the clothes treating agent is contacted with the load in the drum more uniformly, thereby further improving the washing effect.

The foregoing description is only illustrative of the preferred embodiment of the present invention, and is not to be construed as limiting the invention, but is to be construed as limiting the invention to any and all simple modifications, equivalent variations and adaptations of the embodiments described above, which are within the scope of the invention, may be made by those skilled in the art without departing from the scope of the invention.
