Abstract
Description
Technical Field
[0001] This application relates to the technical field of dishwashers, and particularly to a residual water temporary storage device and a dishwasher. Background Art
[0002] After the washing of existing dishwashers is completed, most of them use a drainage pump for drainage. However, limited by the working characteristics of the drainage pump, the washing water often cannot be completely drained, resulting in a small amount of residual water remaining at the bottom of the sink of the dishwasher after the drainage is completed.
[0003] The long-term accumulation of residual water inside the dishwasher is likely to breed bacteria, which will then cause secondary pollution to the tableware during the washing of the tableware, affecting the health of users. In addition, the long-term accumulation of residual water will also produce an odor, making the dishwasher emit a pungent and unpleasant smell when the user opens it, seriously affecting the user experience. Summary of the Invention
[0004] Based on this, it is necessary to provide a residual water temporary storage device and a dishwasher for the problem that the residual water existing inside the dishwasher will cause secondary pollution to the tableware during the washing of the tableware.
[0005] A residual water temporary storage device includes:
[0006] A temporary storage member, which forms a temporary storage cavity;
[0007] A water suction and drainage member, which is communicated with the temporary storage cavity and can be communicated with the inner container of the dishwasher;
[0008] The residual water temporary storage device includes a first state and a second state. When the residual water temporary storage device is in the first state, the water suction and drainage member extracts the residual water in the inner container to the temporary storage cavity. When the residual water temporary storage device is in the second state, the water suction and drainage member extracts the residual water in the temporary storage cavity and discharges it into the inner container.
[0009] In one embodiment, when the residual water temporary storage device is in the first state, the temporary storage member is configured to be able to increase the volume of the temporary storage cavity;
[0010] And / or, when the residual water temporary storage device is in the second state, the temporary storage member is configured to be able to reduce the volume of the temporary storage cavity.
[0011] In one embodiment, when the residual water temporary storage device is in the first state, the temporary storage member can increase the volume of the temporary storage cavity under the positive pressure generated by the water suction and drainage member;
[0012] And / or, when the residual water storage device is in the second state, the storage member can reduce the volume of the storage chamber under the action of the negative pressure generated by the water absorption and drainage member.
[0013] In one embodiment, the storage member includes a cylinder and a piston. A storage chamber is formed inside the cylinder. The piston is movably installed inside the cylinder. During the movement of the piston, the piston can compress or release the storage chamber. When the piston compresses the storage chamber, the volume of the storage chamber increases, and when the piston compresses the storage chamber, the volume of the storage chamber decreases.
[0014] When the residual water storage device is in the first state, the piston releases the storage chamber. When the residual water storage device is in the second state, the piston compresses the storage chamber.
[0015] In one embodiment, the radius R of the cylinder, the volume V of the storage chamber, and the stroke L of the piston inside the cylinder satisfy the relationship:
[0016]
[0017] In one embodiment, the piston and the cylinder are in interference fit.
[0018] In one embodiment, the storage member is elastic. When the residual water storage device is in the first state, the storage member expands. When the residual water storage device is in the second state, the storage member collapses.
[0019] In one embodiment, the water absorption and drainage member is a gear pump.
[0020] A dishwasher includes an inner container, a main drainage member, and the residual water storage device as described above. The main drainage member is communicated with the inner container.
[0021] In one embodiment, a main drainage port and a water absorption and drainage port are formed on the inner container. The main drainage port is communicated with the main drainage member, and the water absorption and drainage port is communicated with the water absorption and drainage member.
[0022] When the dishwasher is working, the main drainage port is higher than the water absorption and drainage port in the gravity direction.
[0023] The above-mentioned residual water storage device can extract the residual water in the inner container and temporarily store the extracted residual water in the residual water storage device, avoiding problems such as internal moisture return and odor generation in the inner container due to the long-term storage of residual water.
[0024] When the dishwasher cleans the tableware and chopsticks in the inner tank again, the residual water storage device will drain the temporarily stored residual water back into the inner tank. When the main drain drains the inner tank, the residual water will be discharged to the outside of the dishwasher together with other cleaning water in the inner tank by the main drain.
[0025] Finally, after the dishwasher completes the cleaning work, the residual water storage device will continue to pump the cleaning water in the inner tank into its own internal storage to avoid the long-term storage of residual water in the inner tank until the next cleaning work of the dishwasher, and then drain the residual water back into the inner tank.

[0039] Referring to Figure 1 , a dishwasher provided by an embodiment of the present application includes an inner container 20, a main drain part 21 and a residual water temporary storage device 10. The inner container 20 is used to provide a storage space for tableware and chopsticks, so as to clean the tableware and chopsticks in the inner container 20 through the dishwasher. A main drain port 23 is formed on the inner container 20, and the main drain part 21 is communicated with the main drain port 23 on the inner container 20. After the dishwasher cleans the tableware and chopsticks in the inner container 20, the cleaning water is discharged to the outside of the dishwasher through the main drain part 21 through the main drain port 23, such as the inner drain port of the user's cabinet.
[0040] The main drain part 21 in the traditional dishwasher is an impeller pump. When the impeller pump drains the inner container 20, there are certain requirements for the water level and liquid level in the inner container 20. When the water level in the inner container 20 is low, the impeller pump cannot completely drain the water in the inner container 20, which will lead to residual water in the inner container 20, and these residual waters will cause problems such as moisture return and odor generation inside the inner container 20.
[0041] For this reason, a residual water temporary storage device 10 is provided in the dishwasher. The residual water temporary storage device 10 can extract the residual water in the inner container 20 and temporarily store the extracted residual water in the residual water temporary storage device 10, so as to avoid problems such as moisture return and odor generation inside the inner container 20 caused by the long-term storage of residual water in the inner container 20.
[0042] When the dishwasher cleans the tableware and chopsticks in the inner container 20 again, at this time, the residual water temporary storage device 10 will re-drain the temporarily stored residual water in the inner container 20. When the main drain part 21 drains the inner container 20, the residual water will be discharged to the outside of the dishwasher together with other cleaning water in the inner container 20 by the main drain part 21.
[0043] Finally, after the dishwasher completes the cleaning work, the residual water temporary storage device 10 will continue to extract the cleaning water in the inner container 20 into its own interior for temporary storage, so as to avoid the long-term storage of residual water in the inner container 20 until the next cleaning work of the dishwasher, and then re-drain the residual water into the inner container 20.
[0044] Specifically, the residual water storage device 10 includes a storage member 11 and a water absorption and drainage member 12. A storage cavity is formed inside the storage member 11. The water absorption and drainage member 12 is communicated with the storage cavity, and the water absorption and drainage member 12 can also be communicated with the inner liner 20 of the dishwasher, so as to pump the residual water in the inner liner 20 into the storage cavity through the water absorption and drainage member 12, or pump the residual water in the storage cavity into the inner liner 20.
[0045] Among them, the residual water storage device 10 includes a first state and a second state. When the residual water storage device 10 is in the first state, the water absorption and drainage member 12 pumps the residual water in the inner liner 20 into the storage cavity. When the residual water storage device 10 is in the second state, the water absorption and drainage member 12 pumps the residual water in the storage cavity and discharges it into the inner liner 20.
[0046] In this way, after the dishwasher finishes cleaning the tableware, the residual water storage device 10 can be switched to the first state, so that the residual water in the inner liner 20 is pumped into the storage cavity through the water absorption and drainage member 12 for temporary storage, avoiding problems such as moisture return and odor generation inside the inner liner 20 due to long-term storage of residual water in the inner liner 20.
[0047] When the dishwasher performs the cleaning work on the tableware again, the residual water device can be switched to the second state, so that the residual water in the storage cavity is re-discharged into the inner liner 20 through the water absorption and drainage member 12, so that the residual water will be discharged to the outside of the dishwasher together with other cleaning water in the inner liner 20 by the main drainage member 21, completing the discharge of the residual water.
[0048] In the actual use process, in order to prevent the residual water in the storage member 11 from leaking to the outside and causing the dishwasher to leak, the storage cavity in the storage member 11 needs to be sealed. When the residual water storage device 10 is in the first state, the water absorption and drainage member 12 pumps the residual water in the inner liner 20 into the storage cavity. Since the storage cavity is in a sealed state, when the residual water in the storage cavity gradually increases, the air pressure in the storage cavity rises, thus affecting the pumping effect of the water absorption and drainage member 12.
[0049] Therefore, when the residual water storage device 10 is in the first state, the storage member 11 is configured to be able to increase the volume of the storage cavity, so as to avoid the compression of air or residual water by increasing the volume of the storage cavity, thereby ensuring that the water absorption and drainage member 12 can normally pump the residual water in the inner liner 20.
[0050] When the residual water storage device 10 is in the second state, the storage member 11 is configured to be able to reduce the volume of the storage cavity. The reduction of the volume of the storage cavity not only facilitates the complete discharge of the residual water, but also prevents air from entering the storage cavity, thereby preparing for the next extraction of the residual water in the inner tank 20 by the water suction and drainage member 12. So that after the water suction and drainage member 12 extracts the residual water in the inner tank 20 into the storage cavity next time, the storage cavity can increase again to ensure that the water suction and drainage member 12 can normally extract the residual water in the inner tank 20.
[0051] It can be understood that an additional driving component can be provided for the storage member 11 to increase or decrease the volume of the storage cavity, or the volume of the storage cavity can be directly reduced by the water pressure or suction force applied by the water suction and drainage member 12. Specifically, in some other embodiments of the present application, when the residual water storage device 10 is in the first state, the storage member 11 can increase the volume of the storage cavity under the positive pressure generated by the water suction and drainage member 12.
[0052] The positive pressure generated by the water suction and drainage member 12 refers to that after the water suction and drainage member 12 extracts the residual water and inputs it into the storage cavity, under the action of the water suction and drainage member 12, the residual water will have a certain water pressure, and this water pressure is the positive pressure generated by the water suction and drainage member 12. When the positive pressure acts on the storage member 11 or the parts inside the storage member 11, the volume of the storage cavity will increase to accommodate the increase in the residual water in the storage cavity.
[0053] When the residual water storage device 10 is in the second state, the storage member 11 can reduce the volume of the storage cavity under the action of the negative pressure generated by the water suction and drainage member 12. Among them, the negative pressure generated by the water suction and drainage member 12 means that when the residual water in the storage cavity is drawn away by the water suction and drainage member 12, a negative pressure will be generated in the storage cavity due to the suction force of the water suction and drainage member 12. Under the action of the negative pressure, the volume of the storage member 11 will decrease to adapt to the reduction of the residual water in the storage cavity.
[0054] In some embodiments, the storage member 11 includes a cylinder 13 and a piston. A storage cavity is formed inside the cylinder 13. The piston is movably installed inside the cylinder 13, and according to the different movement directions of the piston, the piston can compress or release the storage cavity. When the piston moves towards the water suction and drainage member 12, the piston compresses the storage cavity, thereby gradually reducing the volume of the storage cavity. When the piston moves away from the water suction and drainage member 12, the piston releases the storage cavity, thereby gradually increasing the volume of the storage cavity.
[0055] Among them, when the residual water storage device 10 is in the first state, the piston releases the storage cavity, and the volume of the storage cavity increases to accommodate the increase in the residual water in the storage cavity. When the residual water storage device 10 is in the second state, the piston compresses the storage cavity, and the volume of the storage cavity decreases to discharge the residual water in the storage cavity and prepare for the next release of the storage cavity by the piston.
[0056] The movement mode of the piston can be driven by an additional driving component, or an additional driving component can be not provided. The piston releases and compresses the temporary storage cavity solely under the action of the positive pressure and negative pressure of the water suction and drainage component 12.
[0057] When no additional driving component is provided to drive the piston, when the residual water temporary storage device 10 is in the first state, the water suction and drainage component 12 extracts the residual water in the inner container 20 to generate positive pressure to the piston, thereby driving the piston to move in the cylinder body 13, and finally releasing the temporary storage cavity to increase the volume of the temporary storage cavity. When the residual water temporary storage device 10 is in the second state, the water suction and drainage component 12 extracts the residual water in the temporary storage cavity, thereby forming negative pressure in the temporary storage cavity. The piston compresses the temporary storage cavity under the drive of the negative pressure to reduce the volume of the temporary storage cavity.
[0058] Specifically, in some embodiments, the radius R of the cylinder body 13, the volume V of the temporary storage cavity, and the stroke L of the piston in the cylinder body 13 satisfy the relationship:
[0059]
[0060] In this way, the formation of the piston in the cylinder body 13 can be the same as or close to the length of the temporary storage cavity, so that when the piston compresses the temporary storage cavity, the volume of the temporary storage cavity can be reduced to close to 0, which is beneficial to completely discharging the residual water in the temporary storage cavity.
[0061] Furthermore, the piston is in interference fit with the cylinder body 13, so that a certain frictional force will be generated between the piston and the inner wall of the cylinder body 13, and under the action of the frictional force between the piston and the cylinder body 13, the piston will not move by itself, thereby avoiding the residual water in the temporary storage cavity flowing back into the inner container 20 due to the movement of the piston.
[0062] In some other embodiments, the temporary storage member 11 has elasticity. When the residual water temporary storage device 10 is in the first state, the temporary storage member 11 expands to increase the volume of the temporary storage cavity in the temporary storage member 11. When the residual water temporary storage device 10 is in the second state, the temporary storage member 11 collapses to reduce the volume of the temporary storage cavity in the temporary storage member 11.
[0063] That is to say, the material of the temporary storage member 11 can be rubber and form a structure similar to a balloon. After the water suction and drainage component 12 sucks the residual water in the inner container 20 and inputs it into the temporary storage member 11, the temporary storage member 11 will expand and deform under the action of the residual water, so as to adapt to the increase of the residual water in the temporary storage cavity. When the water suction and drainage component 12 extracts the residual water in the temporary storage member 11, the temporary storage member 11 is no longer under the pressure from the residual water, and the temporary storage member 11 will recover the deformation and collapse to completely discharge the residual water and prepare for the next expansion.
[0064] In some embodiments of the present application, the water absorption and drainage member 12 is a gear pump. A gear pump is a rotary pump that relies on the change in the working volume formed between the pump cylinder and the meshing gears and the movement to transport or pressurize the liquid. It consists of two gears, a pump body, and front and rear covers to form two closed spaces. When the gears rotate, the volume of the space on the side where the gears disengage changes from small to large, creating a vacuum to suck in the liquid. The volume of the space on the side where the gears mesh changes from large to small, squeezing the liquid into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of the two gears.
[0065] By changing the rotation direction of the two gears, the positions of the suction chamber and the discharge chamber in the gear pump can be changed, thereby changing the suction and discharge directions of the gear pump. Specifically, the two closed spaces formed by the two gears, the pump body, and the front and rear covers are respectively defined as the first space and the second space. The first space is connected to the inner tank 20, and the second space is connected to the temporary storage chamber. The two gears are respectively the first gear and the second gear.
[0066] When the first gear rotates around the first circumferential direction and the second gear rotates around the second circumferential direction, and the first circumferential direction and the second circumferential direction are opposite, at this time, the first space forms a suction chamber, and the second space forms a discharge chamber, thereby sucking the residual water in the inner tank 20 into the temporary storage chamber, and the residual water storage device 10 is in the first state.
[0067] When the first gear rotates around the second circumferential direction and the second gear rotates around the first circumferential direction, at this time, the first space forms a discharge chamber, and the second space forms a suction chamber, thereby sucking the residual water in the temporary storage chamber into the inner tank 20, and the residual water storage device 10 is in the second state. In this way, by changing the rotation directions of the first gear and the second gear, the residual water storage device 10 can be switched between the first state and the second state.
[0068] In some embodiments of the present application, in order to connect the inner tank 20 to the main drainage member 21 and the water absorption and drainage member 12, a main drainage port 23 and a water absorption and drainage port 22 are provided on the inner tank 20. The main drainage port 23 is connected to the main drainage member 21, and the water absorption and drainage port 22 is connected to the water absorption and drainage member 12. The main drainage member 21 has a higher requirement for the water level, while the water absorption and drainage member 12 has a lower requirement for the water level. Therefore, when the dishwasher is working, the main drainage port 23 is higher than the water absorption and drainage port 22 in the direction of gravity, so as to drain most of the cleaning water in the inner tank 20 through the main drainage port 23, and then drain the remaining residual water through the water absorption and drainage member 12 port.
[0069] The embodiments of the present application also provide a method for removing residual water. Refer to Figure 4 , based on the dishwasher in any of the above embodiments, and includes the following steps:
[0070] S1: In response to the drainage operation of the dishwasher, control the main drainage member 21 to be powered on and start.
[0071] S2: After the main drain component 21 finishes draining, switch the residual water storage device 10 to the first state;
[0072] S3: When the dishwasher performs the draining operation again, control the main drain component 21 to power on and start, and switch the residual water storage device 10 to the second state.
[0073] S4: After the main drain component 21 finishes draining, repeat step S2.
[0074] In step S2, the residual water storage device 10 can extract the residual water in the inner tank 20 and temporarily store the extracted residual water in the residual water storage device 10, preventing the residual water from staying in the inner tank 20 for a long time and causing problems such as moisture return and odor generation inside the inner tank 20.
[0075] In step S3, the residual water storage device 10 will re-drain the temporarily stored residual water inside into the inner tank 20. When the main drain component 21 drains the inner tank 20, the residual water will be discharged to the outside of the dishwasher together with other cleaning water in the inner tank 20 by the main drain component 21.
[0076] In step S4, after the main drain component 21 finishes draining, most of the cleaning water in the inner tank 20 and the residual water from the previous cleaning will be discharged through the main drain component 21. Then repeat step S2, so that the residual water storage device 10 is switched to the first state, and the residual water in the inner tank 20 during this cleaning process is extracted into the storage device until the residual water is discharged when the dishwasher performs the draining operation next time.
[0077] The residual water storage device 10 of this application has at least the following advantages:
[0078] The residual water storage device 10 can extract the residual water in the inner tank 20 and temporarily store the extracted residual water in the residual water storage device 10, preventing the residual water from staying in the inner tank 20 for a long time and causing problems such as moisture return and odor generation inside the inner tank 20.
[0079] When the dishwasher cleans the tableware in the inner tank 20 again, at this time, the residual water storage device 10 will re-drain the temporarily stored residual water inside into the inner tank 20. When the main drain component 21 drains the inner tank 20, the residual water will be discharged to the outside of the dishwasher together with other cleaning water in the inner tank 20 by the main drain component 21.
[0080] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0081] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
