Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a dispenser for a cleaning machine and the cleaning machine. Background Art

[0002] In the related art, in order to effectively improve the drying effect, most dishwashers use a dispenser device to put rinse aid into the dishwasher to reduce the surface tension of water, thereby promoting the flow of water on the surface of tableware, reducing residual water droplets, and further improving the drying effect of tableware.

[0003] Most allocators have the following problems:

[0004] 1. The dispenser is installed on the side wall of the washing chamber or the inner door of the dishwasher. The liquid released by the dispenser flows directly into the washing chamber. A water column must be set to flush the liquid outlet of the dispenser to prevent the rinse agent from remaining.

[0005] Rinse aid is usually a blue liquid that is harmless to the body. However, after washing the dishes, rinse aid (blue liquid) still flows out into the washing chamber. When the user takes the dishes out, the user can see it, which seriously affects the user's perception.

[0006] 2. The dispenser is not directly installed on the washing chamber. The liquid dispensed by the dispenser flows into the washing chamber through the pipe. In this case, the rinse agent will remain in the pipe, resulting in inaccurate amount of liquid dispensed each time; or water during the washing process enters the pipe, diluting the rinse agent, resulting in inaccurate actual amount dispensed.

[0036] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0037] Embodiment 1:

[0038] like Figures 1 to 5 As shown, this embodiment provides a dispenser for a cleaning machine, comprising a shell 1, a water inlet channel 2, a discharge port 11 and a accommodating chamber 3 for accommodating a detergent, wherein the water inlet channel 2, the discharge port 11 and the accommodating chamber 3 are respectively opened on the shell 1, the water inlet 21 of the water inlet channel 2 is connected to an external water supply, the water outlet 22 of the water inlet channel 2 and the liquid outlet of the accommodating chamber 3 are both connected to the inlet of the discharge port 11, and the outlet of the discharge port 11 is connected to the washing chamber of the cleaning machine.

[0039] In this embodiment, the cleaning machine is preferably a dishwasher, but can also be a washing machine, and of course can also be other types of cleaning equipment. The cleaning machine in this embodiment is described by taking a dishwasher as an example, and other types of cleaning equipment are not described in detail. The dishwasher has a washing chamber, and a dispenser is arranged on the side wall inside the washing chamber. The dispenser connects the water outlet 22 of the water inlet channel 2 and the liquid outlet of the accommodating chamber 3 with one end of the discharge port 11 respectively, so that the washing water in the water inlet channel 2 flushes the detergent put out at the liquid outlet position of the accommodating chamber 3 and takes away all of it and puts it into the washing chamber, so that the dispenser can make full use of the external water supply, and the water flows into the water inlet channel 2 in the dispenser to flush the detergent remaining at the liquid outlet position of the accommodating chamber 3 so that it flows into the washing chamber together, and the detergent residue phenomenon will not occur, thereby effectively solving the detergent or dish rinse agent residue problem. The detergent in this embodiment is preferably a dish rinse agent, but is not limited to a dish rinse agent. Other more suitable detergents can also be selected according to actual scene requirements. The detergent in this embodiment is described by taking a dish rinse agent as an example, and other types of detergents are not described in detail.

[0040] Furthermore, a blocking member 4 is provided at the intersection of the water outlet 22 of the water inlet channel 2 and the liquid outlet of the accommodating chamber 3, which has a simple structure and reasonable design and can effectively slow down the flow rate of water in the water inlet channel.

[0041] In this embodiment, when the flow rate of the washing water in the water inlet channel 2 is relatively high, a blocking member 4 is provided at the intersection of the water outlet 22 of the water inlet channel 2 and the liquid outlet of the accommodating chamber 3, so that the flow rate of the water flow can be slowed down, thereby effectively preventing the washing water from directly infiltrating into the accommodating chamber 3 from the liquid outlet of the accommodating chamber 3 to affect the rinse agent.

[0042] Preferably, a liquid filling port 13 connected to the accommodating chamber 3 is provided on the shell 1, and a mounting sleeve 14 is sleeved inside the liquid filling port 13 so that the shell 1 can rotate around the mounting sleeve 14. The design is reasonable and can facilitate the connection between the water inlet channel of the distributor and the external water supply.

[0043] Furthermore, a sealing cover 9 is provided at the position of the liquid filling port 13, and the sealing cover 9 is detachably connected to the mounting sleeve 14, which has a simple structure and is easy to operate, so that the user can add the cleaning agent conveniently.

[0044] Specifically, a fixing seat 15 is provided at the position of the liquid filling port 13, and the mounting sleeve 14 is rotatably connected to the fixing seat 15 through a screw member. The design is reasonable, and the housing can rotate around the mounting sleeve.

[0045] In this embodiment, a ventilation hole is provided on the sealing cover 9 so that there is no risk of detergent overflowing from the ventilation hole during liquid addition or use. A fixing seat 15 is provided at the position of the liquid filling port 13, and a through hole is provided on the fixing seat 15 to facilitate the detergent to flow into the accommodating chamber 3 after passing through the through hole. A mounting sleeve 14 is sleeved inside the liquid filling port 13, and the bottom of the mounting sleeve 14 is movably connected to the fixing seat through a screw member. During the installation of the dishwasher, if the water inlet channel 2 of the dispenser is inconvenient to be connected to the external water supply pipeline, the user can push the shell 1 of the dispenser to rotate around the mounting sleeve 14, and the water inlet channel 2 is correspondingly connected to the external water supply pipeline by driving the shell 1 to rotate a certain angle, thereby effectively improving the user's usage experience. In this embodiment, when the dispenser is installed on the dishwasher, the dispenser is prone to shaking due to the use of a hoisting structure. In order to effectively solve the above problem, support ribs can be provided on the top of the shell 1, and the support ribs abut against the top wall inside the dishwasher to prevent the dispenser from shaking. In addition, limiting ribs can be symmetrically provided on both sides of the shell 1, and the limiting ribs abut against the inner wall inside the dishwasher, thereby ensuring that the dispenser can play a limiting role in installation regardless of whether it is installed upright or reversed, and at the same time preventing the shell 1 from rotating or swinging.

[0046] Preferably, it also includes a liquid outlet cavity 6 and a liquid outlet distribution mechanism 7, wherein the liquid outlet cavity 6 is connected to the accommodating cavity 3, and the liquid outlet distribution mechanism 7 is used to connect or isolate the accommodating cavity 3 and the liquid outlet cavity 6. Its structure is simple and compact, and it is convenient to control the opening and closing between the accommodating cavity and the liquid outlet cavity.

[0047] Furthermore, it also includes a buffer chamber 5, one side of the buffer chamber 5 is connected to the accommodating chamber 3, and the other side is connected to the liquid outlet chamber 6. The liquid outlet distribution mechanism 7 is used to connect or isolate the accommodating chamber 3 and the buffer chamber 5, and connect or isolate the buffer chamber 5 and the liquid outlet chamber 6. Its design is reasonable and can further improve the accuracy of the actual amount of rinse agent added.

[0048] In this embodiment, the dispenser includes a buffer chamber 5, a liquid outlet chamber 6 and a liquid outlet dispensing mechanism 7, wherein the accommodating chamber 3 is used to accommodate the rinse agent, and the buffer chamber 5 is arranged on one side of the accommodating chamber 3. By presetting the volume of the buffer chamber 5 to a suitable space, the volume of the rinse agent released each time is quantitative, and the amount of the rinse agent released will not be affected by time, and the amount of the rinse agent released due to the height of the liquid in the liquid outlet chamber 6 can also be avoided. The bottom of the buffer chamber 5 and the bottom of the accommodating chamber 3 are opened to connect the two, and the liquid outlet chamber 6 is arranged at one side of the buffer chamber 5, and an opening is opened on the side wall of the bottom of the buffer chamber 5 to connect the buffer chamber 5 with the liquid outlet chamber 6. , so that the rinse agent in the buffer chamber 5 flows into the liquid outlet chamber 6 through the opening at the bottom of the buffer chamber 5. After entering the liquid outlet chamber 6, the rinse agent flows downward under the influence of gravity, and then is put into the washing chamber through the liquid outlet and the discharge port 11 of the liquid outlet chamber 6. When the dishwasher is supplied with water from the outside, the external washing water flows into the water inlet channel 2 from the water inlet 21 of the water inlet channel 2. The washing water that has entered the water inlet channel 2 flushes the rinse agent at the liquid outlet position of the accommodating chamber 3 at the confluence position of the water outlet 22 of the water inlet channel 2 and the liquid outlet of the accommodating chamber 3, and takes away all of it and puts it into the washing chamber, so that no residual rinse agent occurs. In this embodiment, the liquid outlet of the liquid outlet chamber 6 and the water outlet 22 of the water inlet channel 2 are both connected to one end of the discharge port 11, and a blocking member 4 is provided between the liquid outlet of the liquid outlet chamber 6 and the water outlet 22 of the water inlet channel 2 to prevent the washing water from directly flowing into the liquid outlet chamber 6. In order to better solve the problem of residual rinse agent, the front side of the blocking member 4 is arranged in the vertical direction and tilted outward, so that the rinse agent is not easy to remain on the blocking member 4.

[0049] Furthermore, the liquid distribution mechanism 7 includes a driving device 71, a transmission assembly 72 and a seal 73. The output end of the driving device 71 is connected to one end of the transmission assembly 72. A seal 73 is provided on the other end of the transmission assembly 72. The seal 73 is sequentially passed through the accommodating chamber 3 and the buffer chamber 5 to seal the connection between the accommodating chamber 3 and the buffer chamber 5 or the connection between the buffer chamber 5 and the liquid outlet chamber 6. The design is reasonable and can facilitate the control of the connection or isolation between the accommodating chamber, the buffer chamber and the liquid outlet chamber.

[0050] Specifically, the sealing member 73 includes a connecting portion 731, a contact head 732, a telescopic portion 733 and a sealing lip 734, wherein a contact head 732 is arranged at one end of the connecting portion 731, and the contact head 732 abuts against the connection between the buffer chamber 5 and the accommodating chamber 3, and a telescopic portion 733 is arranged at the other end of the connecting portion 731, and the transmission component 72 passes through the telescopic portion 733 and is connected to the connecting portion 731, and the sealing lip 734 is arranged inside the buffer chamber 5 and is driven by the transmission component 72 to seal the connection between the accommodating chamber 3 and the buffer chamber 5 or the connection between the buffer chamber 5 and the liquid outlet chamber 6. It has a simple structure and a reasonable and ingenious design, which can further improve the sealing effect of the partition between the accommodating chamber, the buffer chamber and the liquid outlet chamber.

[0051] In this embodiment, the telescopic portion 733 is arranged on a side of the liquid outlet chamber 6 away from the buffer chamber 5, one end of the connecting portion 731 is connected to the telescopic portion 733, and the other end passes through the liquid outlet chamber 6 to extend into the buffer chamber 5, so that the contact head 732 abuts against the connection between the buffer chamber 5 and the liquid outlet chamber 6, and a sealing lip 734 is arranged on the side wall of the connecting portion 731. The sealing lip 734 is arranged inside the buffer chamber 5. The movement of the connecting portion 731 drives the sealing lip 734 to abut against the connection position between the accommodating chamber 3 and the buffer chamber 5, and the buffer chamber 5 and the liquid outlet chamber 6, so as to seal or open the connection between the accommodating chamber 3 and the buffer chamber 5 or the connection between the sealed buffer chamber 5 and the liquid outlet chamber 6. When the dispenser of the dishwasher is in an initial state, the sealing lip 734 blocks the connection between the accommodating chamber 3 and the buffer chamber 5. When it is necessary to add rinse agent into the washing chamber, the driving device 71 drives the transmission assembly 72 to move backward to drive the sealing lip 734 to move backward, so that the sealing lip 734 seals the connection between the buffer chamber 5 and the liquid outlet chamber 6, and then opens the connection between the accommodating chamber 3 and the buffer chamber 5 to allow the rinse agent to flow from the accommodating chamber 3 to the buffer chamber 5. When the preset amount of addition is reached, the driving device 71 drives the transmission assembly 72 to move forward to drive the sealing lip 734 to perform a forward reset movement, so that the sealing lip 734 seals the connection between the accommodating chamber 3 and the buffer chamber 5, and then opens the connection between the buffer chamber 5 and the liquid outlet chamber 6 to allow the rinse agent to flow from the buffer chamber 5 to the liquid outlet chamber 6. The rinse agent entering the liquid outlet chamber 6 continues to flow toward the washing chamber, so that the rinse agent and the washing water are combined and then distributed to the washing chamber through the discharge port 11. The driving device 71 in this embodiment is preferably a solenoid valve, but is not limited to a solenoid valve, and other more suitable driving devices 71 may be selected according to actual needs.

[0052] Preferably, the transmission assembly 72 includes a transmission rod 721 and an elastic element 722, wherein one end of the transmission rod 721 is connected to the driving device 71, and the other end is connected to the sealing member 73. An inner cavity with one end open is defined inside the transmission rod 721, a positioning seat 16 is provided on the shell 1 and the positioning seat 16 at least partially extends into the inner cavity, the elastic element 722 is provided in the inner cavity and one end of the elastic element 722 abuts against the positioning seat 16, and the other end abuts against the inner wall of the inner cavity close to one end of the sealing member 73. The design is reasonable and can effectively improve the reliability of the operation of the liquid distribution mechanism.

[0053] Furthermore, a vent cavity 12 is provided above the liquid outlet cavity 6, one end of the vent cavity 12 is connected to the liquid outlet cavity 6, and the other end is connected to the buffer cavity 5. The structure is simple, and the buffer cavity and the liquid outlet cavity can be connected through the vent cavity to effectively prevent the rinse agent from not flowing into the liquid outlet cavity due to negative pressure in the buffer cavity.

[0054] In this embodiment, a first cavity is arranged above the liquid outlet cavity 6, and a second cavity is arranged above the buffer cavity 5. The first cavity is communicated with the second cavity at one end away from the liquid outlet cavity 6 to form a ventilation cavity 12, so that the ventilation cavity 12 is communicated with the washing cavity of the dishwasher through the discharge port 11. More preferably, the volume of the first cavity is greater than that of the second cavity. When the rinse agent in the buffer cavity 5 is released into the liquid outlet cavity 6, the gas in the first cavity can flow into the second cavity to be supplemented into the second cavity, thereby effectively preventing the rinse agent from not flowing into the liquid outlet cavity 6 due to the negative pressure problem in the buffer cavity 5. Of course, in the present embodiment, no ventilation chamber 12 is provided between the buffer chamber 5 and the liquid outlet chamber 6. Vent holes may be provided above the buffer chamber 5 and the liquid outlet chamber 6, and the vent holes are connected to the outside, so that the air pressure inside the buffer chamber 5 and the liquid outlet chamber 6 and the external air pressure are kept balanced. However, it is still better to choose a structure in which the ventilation chamber 12 is provided between the buffer chamber 5 and the liquid outlet chamber 6. Since no separate ventilation holes are provided for the buffer chamber 5 and the liquid outlet chamber 6, there is no risk of washing water overflowing from the ventilation holes during the water supply process.

[0055] In particular, it also includes a liquid level detection device 8, which is arranged on the shell 1 and is used to detect the liquid level in the accommodating chamber 3. Its design is reasonable and ingenious, which can further improve the reliability of the dispenser and the user's experience.

[0056] In this embodiment, the liquid level detection device 8 is arranged outside the accommodating chamber 3 to detect the liquid level of the rinse agent in the accommodating chamber 3. When the liquid level of the rinse agent in the accommodating chamber 3 is low, the control device of the dishwasher reminds the user according to the detection result, thereby effectively ensuring that the rinse agent in the accommodating chamber 3 is always in a saturated state.

[0057] Embodiment 2:

[0058] like Figure 1 and 6 As shown, the present embodiment provides a dispenser for a washing machine, which includes the dispenser as described in the first embodiment, wherein the dispenser of the present embodiment is the same as the dispenser described in the first embodiment in that the water outlet 22 of the water inlet channel 2 and the liquid outlet of the accommodating chamber 3 are respectively connected to one end of the discharge port 11, and the washing water in the water inlet channel 2 flushes the detergent put out from the liquid outlet position of the accommodating chamber 3 and takes it all away and puts it into the washing chamber, so that the dispenser can make full use of the external water supply, and the water flows into the water inlet channel 2 in the dispenser to flush the detergent remaining at the liquid outlet position of the accommodating chamber 3 so that the detergent will not remain, thereby effectively solving the problem of detergent or rinse agent residue.

[0059] In this embodiment, the cleaning machine is preferably a dishwasher, but can also be a washing machine, and of course can also be other types of cleaning equipment. The cleaning machine in this embodiment is described by taking a dishwasher as an example, and other types of cleaning equipment are not described in detail. The detergent in this embodiment is preferably a rinse agent, but is not limited to a rinse agent, and other more suitable detergents can be selected according to actual scene requirements. The detergent in this embodiment is described by taking a rinse agent as an example, and other types of detergents are not described in detail.

[0060] The dispenser of this embodiment is different from the dispenser of the first embodiment in that a buffer chamber 5 is provided at one side of the accommodating chamber 3 in the housing 1, and the volume of the buffer chamber 5 is preset to a suitable space, so that the amount of the rinse agent released each time is quantitative, and the amount of the rinse agent is not affected by time, and the amount of the rinse agent released due to the liquid level in the liquid outlet chamber 6 is also prevented from being affected. An opening is provided at the bottom of the buffer chamber 5 and the bottom of the accommodating chamber 3 so that the two are connected to each other, a liquid outlet chamber 6 is provided at one side of the buffer chamber 5, and an opening is provided on the side wall of the bottom of the buffer chamber 5 so that the buffer chamber 5 and the liquid outlet chamber 6 are connected to each other. Thereby, the rinse agent in the accommodating chamber 3 flows into the liquid outlet chamber 6 through the buffer chamber 5. After entering the liquid outlet chamber 6, the rinse agent flows downward due to the influence of gravity, and then is put into the washing chamber through the liquid outlet and the discharge port 11 of the liquid outlet chamber 6. When the dishwasher is supplied with water from the outside, the external washing water flows into the water inlet channel 2 from the water inlet 21 of the water inlet channel 2. The washing water that has entered the water inlet channel 2 flushes the rinse agent at the liquid outlet of the accommodating chamber 3 at the confluence position of the water outlet 22 of the water inlet channel 2 and the liquid outlet of the accommodating chamber 3, and takes away all of it and puts it into the washing chamber, so that no residue of the rinse agent occurs.

[0061] In addition, in the present embodiment, the telescopic portion 733 is arranged on the outside of the accommodating chamber 3, and the transmission component 72 passes through the telescopic portion 733 and the side wall of the accommodating chamber 3 in sequence at the end away from the driving device 71, and then extends into the hollow cavity of the connecting portion 731 to connect the transmission component 72 and the sealing member 73 together. A sealing lip 734 is arranged on the side wall of the connecting portion 731, and the sealing lip 734 is arranged inside the buffer chamber 5. The sealing lip 734 is driven by the movement of the connecting portion 731 to abut against the connecting position between the accommodating chamber 3 and the buffer chamber 5, and the buffer chamber 5 and the liquid outlet chamber 6, thereby sealing or opening the connecting position between the accommodating chamber 3 and the buffer chamber 5, or the connecting position between the sealed buffer chamber 5 and the liquid outlet chamber 6. In the initial state of the dispenser in this embodiment, the sealing lip 734 seals the connection between the accommodating chamber 3 and the buffer chamber 5. When it is necessary to add rinse agent into the washing chamber, the driving device 71 drives the transmission assembly 72 to move forward to drive the sealing lip 734 to move forward, so that the sealing lip 734 seals the connection between the buffer chamber 5 and the liquid outlet chamber 6, and then opens the connection between the accommodating chamber 3 and the buffer chamber 5 to allow the rinse agent to flow from the accommodating chamber 3 to the buffer chamber 5. When the preset amount of addition is reached, the driving device 71 drives the transmission assembly 72 to move backward to drive the sealing lip 734 to move backward, so that the sealing lip 734 seals the connection between the accommodating chamber 3 and the buffer chamber 5, and then opens the connection between the buffer chamber 5 and the liquid outlet chamber 6 to allow the rinse agent to flow from the buffer chamber 5 to the liquid outlet chamber 6. The driving device 71 in this embodiment is preferably a solenoid valve, but is not limited to a solenoid valve. Other more suitable driving devices 71 can also be selected according to actual needs.

[0062] Embodiment three:

[0064] In this embodiment, the cleaning machine is preferably a dishwasher, but can also be a washing machine, and of course can also be other types of cleaning equipment. The cleaning machine in this embodiment is described by taking a dishwasher as an example, and other types of cleaning equipment are not described in detail. The detergent in this embodiment is preferably a rinse agent, but is not limited to a rinse agent, and other more suitable detergents can be selected according to actual scene requirements.
