Description

Technical Field

[0001] The invention relates to the technical field of washing equipment, in particular to a detergent dispensing component and a dishwasher. Background Art

[0002] At present, with the improvement of living standards, the use of dishwashers has gradually begun to enter the homes of the general public. The working principle of traditional dishwashers is to spray water containing detergent onto the surface of dishes through the rotation of the self-rotating spray arm, and clean the dishes through chemical action. Therefore, placing detergent in the cleaning process is an essential step.

[0003] The prior art is to manually add washing blocks or a certain volume of dishwashing powder into the washing chamber of the dishwasher, and the operator needs to add a fixed amount of consumables before each washing. The user operation is relatively cumbersome and extremely inconvenient.

[0004] In the field of dishwashers and washing machines, some products also use liquid detergent as a cleaning agent. Liquid detergent is easier to automatically dispense than powder or block detergent. The existing detergent dispensing mechanism uses a liquid pump to directly suck the detergent. Although this method can achieve automatic dispensing, it has stability problems. Specifically: 1. Some detergents are acidic, some are alkaline, and some products even use acidic and alkaline detergents. This situation will cause chemical corrosion or swelling of the liquid pump valve body parts, and the lubricating oil of the metal parts will also be dissolved and lost by the detergent. These factors will cause damage to the liquid pump; 2. When the dishwasher is not used for a long time, or the detergent is not used for a long time, the water content of the detergent in the liquid pump pipeline will continue to evaporate, and its solvent concentration will increase sharply, resulting in viscosity or hardening. At this time, when the liquid pump is started, it will cause pipeline blockage. When the hardened detergent enters the liquid pump, the pump body will be stuck or even damaged. The above two problems require new detergent dispensing components to solve. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a detergent dispensing component and a dishwasher having the same in view of the above-mentioned technical deficiencies, wherein the detergent dispensing mechanism thereof is more stable and durable, has a low failure rate, and is easy to use.

[0006] The technical solution adopted by the present invention is: a detergent dispensing component, comprising:

[0007] The delivery box is configured to hold detergent, the inner cavity of the delivery box is connected to a liquid outlet pipe, the liquid inlet of the liquid outlet pipe is located at the bottom of the inner cavity of the delivery box; the liquid outlet of the liquid outlet pipe passes through the upper part of the inner cavity of the delivery box and is connected to the outside of the delivery box;

[0008] An air pump, wherein the air inlet end of the air pump is connected to the external atmosphere, and the air outlet end of the air pump is connected and coordinated with the air inlet of the inner cavity of the delivery box.

[0009] To further optimize the technical solution, a detergent dispensing assembly also includes a dispensing box seat, the dispensing box seat has an installation slot; the dispensing box can be detachably installed in the installation slot.

[0010] To further optimize the technical solution, a detergent dispensing assembly is provided, wherein a liquid filling port is provided at the upper portion of the inner cavity of the dispensing box, and a sealing cover is installed on the liquid filling port for sealing.

[0011] To further optimize the technical solution, a detergent dispensing assembly further includes a liquid level sensor, and the liquid level sensor is used to measure the detergent liquid level in the dispensing box.

[0012] To further optimize the technical solution, the air pump is a peristaltic pump.

[0013] To further optimize the technical solution, the vertical height of the liquid filling port is lower than that of the liquid outlet.

[0014] To further optimize the technical solution, the cover is provided with an inward chamfer in the vertical direction, and the inward chamfer is constructed for grabbing and placing the delivery box.

[0015] To further optimize the technical solution, a side wall of the delivery box seat is provided with a liquid discharge pipe and an air intake pipe; the inlet of the liquid discharge pipe is sealed and matched with the liquid outlet, and the outlet of the liquid discharge pipe is connected to the external atmosphere; the air inlet end of the air intake pipe is connected and connected with the air outlet end of the air outlet pipe; the air outlet end of the air intake pipe is sealed and matched with the air inlet of the inner cavity of the delivery box.

[0016] To further optimize the technical solution, the flow channel cross section of the outlet portion of the drainage pipe gradually widens from top to bottom and the cross-sectional area gradually increases.

[0017] To further optimize the technical solution, a first one-way valve that is one-way conductive to the inner cavity of the delivery box is installed in the air inlet.

[0018] To further optimize the technical solution, a second one-way valve that conducts in one direction upward is installed in the liquid inlet.

[0019] To further optimize the technical solution, the delivery box seat is provided with an elastic push buckle; the elastic push buckle is installed on the other side wall opposite to the drainage pipe and the air intake pipe, and the elastic push buckle is constructed to push and position the delivery box.

[0020] Another technical solution adopted by the present invention is: a dishwasher, which is equipped with the detergent dispensing assembly described in any one of the above solutions.

[0021] In the technical solution described in the present invention, the mechanism for dispensing detergent is to use an air pump to pressurize the inner cavity of the dispensing box, and discharge the detergent from the inner cavity of the dispensing box through the pressure difference between the inside and the outside; in this process, the air pump has no direct contact with the detergent, and the pump body will not be blocked or damaged due to the viscosity and compaction of the detergent, and the life of the pump body parts will not be reduced due to the acid and alkali corrosion of the detergent. The detergent dispensing box can be removed from the dispensing box seat, and it is more flexible and convenient to add detergent or clean the inner cavity of the dispensing box.

DETAILED DESCRIPTION

[0029] like Figures 1 to 5 As shown, embodiment 1:

[0030] A detergent dispensing assembly includes a dispensing box 3, which is configured to contain detergent. The inner cavity of the dispensing box 3 is connected to a liquid outlet pipe 4, and a liquid inlet 5 of the liquid outlet pipe 4 is placed at the bottom of the inner cavity of the dispensing box 3; a liquid outlet 6 of the liquid outlet pipe 4 passes through the upper part of the inner cavity of the dispensing box 3 and is in communication with the outside of the dispensing box 3;

[0031] The air pump has an air inlet connected to the external atmosphere, and an air outlet connected to the air inlet 14 of the inner cavity of the delivery box 3 through an air outlet pipe 10 .

[0032] To further optimize this embodiment, a liquid filling port 7 is provided at the upper portion of the inner cavity of the delivery box 3 , and a sealing cover 8 is installed in a sealing manner on the liquid filling port 7 .

[0033] To further optimize the present embodiment, a detergent dispensing assembly further includes a dispensing box seat 1 , wherein the dispensing box seat 1 has an installation slot 2 ; the dispensing box 1 can be detachably installed in the installation slot 2 .

[0034] The delivery box can be a disposable consumable box or a non-consumable box that can be repeatedly filled through the liquid filling port 7; the delivery box can be directly installed on the dishwasher and filled with liquid on the dishwasher, or it can be removed from the installation slot 2 and then filled with liquid in a more flexible or convenient space.

[0035] The delivery box 3 can be detachably installed in the installation slot 2. The detergent discharged from the liquid outlet 4 can flow directly into the dishwasher, and can also be connected to the dishwasher in series through other pipelines. When connected to the dishwasher in series with other pipelines, the liquid outlet 6 can be sealed and docked with the series pipeline; the air outlet pipe 10 can be directly docked and sealed with the inner cavity of the delivery box 3, or it can be indirectly connected in series through other air circuits to achieve conduction between the two.

[0036] To further optimize this embodiment, a detergent dispensing component also includes a liquid level sensor, and the liquid level sensor is used to measure the detergent liquid level in the dispensing box. The liquid level sensor can be a capacitive liquid level sensor, a pressure liquid level sensor, a float liquid level sensor, or an optical liquid level sensor. By setting a liquid level sensor, the amount of detergent can be measured and warned. This embodiment uses an optical liquid level sensor 19.

[0037] To further optimize this embodiment, the air pump is a peristaltic pump 9. The air pump can be a peristaltic pump, a diaphragm pump, or a plunger pump. The noise of the peristaltic pump is relatively lower, and the air injected into the inner cavity of the delivery box is easier to quantitatively control. In addition, when the peristaltic pump is not working, it has a self-closing property, which can keep the delivery box isolated from the outside world.

[0038] To further optimize this embodiment, the vertical height of the liquid filling port 7 is lower than the liquid outlet 6, so that when the delivery box 3 is filled with detergent, the maximum liquid level will not exceed the liquid outlet 6, and the detergent will not flow out of the liquid outlet to cause waste.

[0039] To further optimize this embodiment, the cover 8 is provided with an inward chamfer 11 in the vertical direction, and the inward chamfer 11 is configured for grasping and placing the delivery box 3 .

[0040] To further optimize this embodiment, a side wall of the delivery box seat 1 is provided with a liquid discharge pipe 12 and an air intake pipe 13; the inlet of the liquid discharge pipe 12 is sealed and matched with the liquid outlet 6, and the outlet of the liquid discharge pipe 12 is connected to the external atmosphere; the air inlet end of the air intake pipe 13 is connected and connected to the air outlet end of the air outlet pipe 10; the air outlet end of the air intake pipe 13 is sealed and matched with the air inlet 14 of the inner cavity of the delivery box 3.

[0041] A liquid discharge pipe 12 and an air intake pipe 13 are provided on the delivery box seat 1. When the delivery box 3 is placed in the installation slot 2, the air pump can be sealed with the inner cavity of the delivery box 3, and the liquid outlet pipe 4 can be drained with the preset detergent filling position of the dishwasher. There is no need to manually connect the air outlet pipe 10, and there is no need to reserve a longer liquid outlet pipe 4 on the delivery box 3, which is more convenient to use.

[0042] To further optimize this embodiment, the flow channel cross section of the outlet portion 15 of the drainage pipe 12 is gradually widened from top to bottom, and the cross-sectional area gradually increases. This has two advantages: a. The viscosity of the detergent is relatively large. After the work of adding detergent to the dishwasher is completed, the detergent remaining in the outlet portion 15 is easier to flow out, while the thinner pipe will not be easy to discharge the detergent due to the capillary phenomenon, which will cause dryness and blockage over time. b. The water jetted from the bottom of the dishwasher or the water splashed by the dishes is easier to be injected into the flow channel of the outlet portion 15 to rinse the detergent remaining in the flow channel.

[0043] To further optimize this embodiment, a first one-way valve 16 that is one-way connected to the inner cavity of the delivery box 3 is installed in the air inlet 14. The first one-way valve 16 can prevent the detergent from flowing back to the air outlet pipe, ensure the complete isolation of the air pump and the detergent, and can also prevent the detergent from flowing out of the air inlet 14 when the detergent is added to the delivery box 3.

[0044] To further optimize this embodiment, a second one-way valve 17 that is one-way upward is installed in the liquid inlet 5. The second one-way valve 17 is used to prevent the detergent in the liquid outlet pipe 4 from flowing back into the delivery box 3. It is combined with the first one-way valve 16 to keep the inner cavity of the delivery box 3 isolated from the outside in the absence of external pressure difference, thereby preventing the volatilization of the detergent.

[0045] To further optimize this embodiment, the delivery box seat 1 is provided with an elastic push buckle 18; the elastic push buckle 18 is installed on the other side wall opposite to the drainage pipe 12 and the air intake pipe 13, and the elastic push buckle 18 is constructed to push and position the delivery box 3.

[0046] Embodiment 2:

[0047] A dishwasher is provided with the detergent dispensing assembly described in any one of the embodiments 1. The dispensing assembly can be installed on the top or side of the dishwasher, and the detergent flowing out of the liquid outlet pipe 4 can enter the washing cavity of the dishwasher.
