A dishwasher 100 according to a third aspect of the present invention is described below with reference to fig. 1 to 25.

The dishwasher 100 according to an embodiment of the present invention includes: the water tank 2, the spray arm assembly 8, the washing pump 7 and the drainage pump 6 are arranged in the inner container assembly 1. Specifically, the water tank 2 is connected to the liner assembly 1, the water tank 2 is used for supplying water to the liner assembly 1, the water tank 2 is provided with a manual water inlet 204, a user can manually add water to the water tank 2 through the manual water inlet 204, and of course, the water tank 2 can also adopt a mode of non-manual water addition, for example, the user can directly connect the water tank 2 with a tap water pipe, and water is directly supplied to the water tank 2 through the tap water pipe. The spray arm assembly 8 is arranged in the liner assembly 1; the washing pump 7 is respectively connected with the liner assembly 1 and the spray arm assembly 8, and the washing pump 7 is used for pumping water in the liner 11 to the spray arm assembly 8; the draining pump 6 is connected with the inner container assembly 1, and the draining pump 6 is used for draining water in the inner container assembly 1.

The following describes the specific operation of the dishwasher 100 described above: when the dish washing machine 100 is required to be used for cleaning dishes, firstly, a user can select to manually add water to the water tank 2 or directly add water into the water tank 2 by using tap water, after water addition is completed or in the water adding process, water in the water tank 2 flows to the inner container assembly 1, under the action of the washing pump 7, the washing pump 7 pumps water in the inner container assembly 1 to the spray arm assembly 8, the spray arm assembly 8 sprays water on the dishes to be cleaned, washing of the dishes is realized, and after the spraying is finished, the water in the inner container assembly 1 is discharged by using the drainage pump 6.

Advantageously, the water tank 2 may be arranged outside the liner assembly 1, so as to avoid occupying the inner space of the liner assembly 1 and ensure the dish washing efficiency of the liner assembly 1. The water tank 2 can be arranged on the side wall of the liner assembly 1 to shorten the distance between the water tank 2 and the liner assembly 1, so that the water tank 2 can supply water to the liner assembly 1 directly. Preferably, the bottom of the water tank 2 may be higher than the base water inlet 101 of the liner assembly 1. In this way, the water in the water tank 2 can automatically flow to the base water inlet 101 to enter the inner container assembly 1 under the action of gravity under the condition that power (such as pumping) is not needed, so that the structure of the dish washer 100 is simpler, more compact and more reasonable.

In some embodiments, the manual water inlet 204 is closed by a filter screen, which can filter out impurities in the water, and prevent the impurities from entering the water tank 2 and the liner assembly 1 downstream of the water tank 2, so as to ensure the cleaning effect on tableware.

Preferably, as shown in fig. 15, the bottom of the water tank 2 may be provided with a water tank drain valve 23, and the water tank drain valve 23 may be connected to the bottom of the water tank 2 and the bottom of the liner assembly 1, respectively, and the water tank drain valve 23 may be a manual valve or an electric valve. Whether the water tank 2 is communicated with the inner container assembly 1 or not can be controlled by controlling the opening and closing of the water drain valve 23 of the water tank, so that whether water is supplied into the inner container assembly 1 or not can be conveniently controlled.

In some embodiments, the liner assembly 1 may be provided with a liner air inlet 102 and a liner air outlet, when the pressure in the liner assembly 1 is too high, air in the liner assembly 1 may flow out through the liner air outlet, and when the air pressure in the liner assembly 1 is too low, external air may enter the liner 11 through the liner air inlet 102, so as to balance the air pressure inside and outside the liner assembly 1. Further, the water tank 2 may be provided with the water tank air inlet 205, and the water tank air inlet 205 is communicated with the air outlet of the inner container, so that when the air pressure in the inner container assembly 1 is too high, the air in the inner container assembly 1 can sequentially enter the water tank 2 through the air outlet of the inner container and the water tank air inlet 205, thereby balancing the pressure difference in the water tank 2 and the inner container assembly 1, and the air pressure in the water tank 2 can be balanced with the external atmospheric pressure through the manual water filling port 204.

In some embodiments of the present invention, the dishwasher 100 may further include a blower anti-siphon assembly 4, and the blower anti-siphon assembly 4 may include: the body part 41 has a water flow passage 412 and a balance passage 411 therein, one end of the water flow passage 412 (e.g., the left end of the water flow passage 412 shown in fig. 23 and 24) is connected to the outlet of the drain pump 6, and the other end of the water flow passage 412 (e.g., the right end of the water flow passage 412 shown in fig. 23 and 24) is used for drainage, when the dishwasher 100 drains water, the drain pump 6 operates, and water in the liner assembly 1 enters the water flow passage 412 through the drain pump 6 and is discharged (e.g., drained to a drain) through the water flow passage 412. Further, the balancing channel 411 may be connected to the water flow channel 412, and the balancing channel 411 has a vent 4114, and the vent 4114 is used to balance the internal and external air pressure of the water flow channel 412.

Advantageously, as shown in fig. 24, a one-way valve 4118 is disposed in the balance channel 411 for making the air flow conduct unidirectionally in a direction toward the water channel 412 (for example, in a direction from top to bottom as shown in fig. 24), the one-way valve 4118 is disposed between the air vent 4114 and the water channel 412, and the one-way valve 4118 can effectively prevent water in the water channel 412 from entering the balance channel 411 to prevent occurrence of siphoning.

In some embodiments, as shown in fig. 24, the water flow channel 412 may have a U-shape, one open end of the U-shape channel (e.g., the water flow channel inlet 4121 shown in fig. 24) is connected to the outlet of the drain pump 6, and the other open end of the U-shape channel (e.g., the water flow channel outlet 4122 shown in fig. 24) is used for drainage, and the balance channel 411 is connected to the upper portion of the water flow channel 412. When the drain pump 6 works, the drain pump 6 pumps out water in the liner assembly 1, the water enters the water flow channel 412 through the opening end on the left side of the water flow channel 412, then is discharged to a sewer from the opening end on the right side of the water flow channel 412, and the air pressure in the water flow channel 412 can be balanced through the vent 4114 arranged at the top of the balancing channel 411, so that the siphon phenomenon caused by the too low air pressure in the water flow channel 412 is avoided.

Advantageously, at least a portion of the equalization channel 411 may be in communication with and extend upwardly from a side of an upper portion of the water channel 412 proximate to the outlet (e.g., an upper portion of the right side of the water channel 412 as viewed in fig. 24). Therefore, the siphon phenomenon can be further avoided, water in the water flow channel 412 is prevented from entering the balance channel 411, and the air pressure balance effect of the balance channel 411 on the water flow channel 412 can be realized.

Since the balance channel 411 is connected to the water channel 412, water in the water channel 412 inevitably enters the balance channel 411 during the draining process of the drain pump 6, therefore, preferably, the balance channel 411 may be connected to the inner space of the liner assembly 1 for water return, so that water entering the balance channel 411 may flow back into the inner space of the liner assembly 1, thereby avoiding water accumulation in the balance channel 411, and ensuring that the balance channel 411 can effectively balance the air pressure in the water channel 412.

Further, as shown in fig. 24, the equalization channel 411 may include: the first vertical limb 4111, the second vertical limb 4112, and the horizontal limb 4113, the first vertical limb 4111 may extend in an up-down direction (e.g., up-down direction as shown in fig. 24), and a lower end of the first vertical limb 4111 communicates with the water flow passage 412, and a lower end of the first vertical limb 4111 communicates with an upper end of the water flow passage 412; the second vertical limb 4112 may also extend in the up-down direction, and the lower end of the second vertical limb 4112 is connected to the inner space of the liner assembly 1; the horizontal limb 4113 extends horizontally and communicates with the upper end of the first vertical limb 4111 and the upper end of the second vertical limb 4112, respectively. For example, the upper end of the first vertical limb 4111 is connected to and communicates with the right end of the horizontal limb 4113, and the upper end of the second vertical limb 4112 is connected to and communicates with the left end of the horizontal limb 4113, so that when water in the water flow channel 412 enters the horizontal limb 4113 through the first vertical limb 4111 due to the siphon phenomenon, the water can flow into the liner assembly 1 through the second vertical limb 4112, thereby making the structure of the balance channel 411 simpler and more reasonable, and also being convenient for manufacturing.

Advantageously, the bottom wall of the horizontal limb 4113 may be configured to slope downwardly in a direction from the first vertical limb 4111 to the second vertical limb 4112 (e.g., a right-to-left direction as shown in fig. 24) such that when water enters the horizontal limb 4113, the water automatically flows along the downwardly sloped bottom wall to the second vertical limb 4112, thereby effectively draining the water within the equalization channel 411.

In some embodiments, as shown in fig. 24, baffles 4116 inclined downward relative to the free end in the horizontal direction are connected to each of the opposite side walls in the second vertical limb 4112, and the baffles 4116 on the opposite side walls in the second vertical limb 4112 are staggered to form a circuitous path. For example, the baffles 4116 attached to the left side wall of the second vertical leg 4112 extend obliquely downward and rightward, the baffles 4116 attached to the right side wall of the second vertical leg 4112 extend obliquely downward and leftward, and the baffles 4116 attached to the left side wall and the right side wall of the second vertical leg 4112 are staggered in the up-down direction, and when water flows from the horizontal leg 4113 to the second vertical leg 4112, the baffles 4116 in the second vertical leg 4112 can have an effect of guiding the water flow so that the water flow quickly flows to the liner assembly 1. In addition, when the fan 42 in the fan anti-siphon assembly 4 works, part of the air flow in the air supply channel 413 leaks into the balance channel 411, and at this time, the staggered baffles 4116 extending obliquely downwards can effectively block the air flow from flowing through the balance channel 411, so that the efficiency of the fan 42 can be improved, and the leakage amount of the air flow can be reduced.

Since air generally flows at an upper level than water, in order to effectively balance the air pressure in the water flow channel 412, the vent 4114 in the balance channel 411 may be provided at the top of the balance channel 411, in particular, the vent 4114 may be formed at the top wall of the horizontal limb 4113, further, the top surface in the horizontal limb 4113 may be provided with a water blocking rib 4115, the water blocking rib 4115 being connected to the side of the vent 4114 adjacent to the first vertical limb 4111 (e.g., the right side of the vent 4114 as shown in fig. 24), and the water blocking rib 4115 may be used to block the water in the horizontal limb 4113 from flowing out through the vent 4114. Advantageously, the projection of the water barrier 4115 may completely cover the projection of the vent 4114 on the horizontal projection plane to enhance the water barrier effect thereof.

In some embodiments, the water blocking rib 4115 may be L-shaped, and in connection with fig. 24, the water blocking rib 4115 is connected to the right side of the vent 4114, and the water blocking rib 4115 is flush with the right side edge of the vent 4114, the water blocking rib 4115 is L-shaped, and the horizontal extension section of the water blocking rib 4115 is opposite to the vent 4114, and completely blocks the vent 4114.

The reversing structure 43 is disposed in the body 41, the reversing structure 43 is switchable between a first state and a second state, when the reversing structure 43 is in the first state, the air supply passage 413 is isolated from the liner air inlet 102 and the balance passage 411 is communicated with the liner air inlet 102, at this time, the air supply passage 413 is not communicated with the inner space of the liner assembly 1, the fan 42 is not operated, and the balance passage 411 is communicated with the inner space of the liner assembly 1. When the reversing structure 43 is in the second state, the air supply passage 413 is communicated with the liner air inlet 102 and the balance passage 411 is isolated from the liner air inlet 102, at this time, the air supply passage 413 is communicated with the inner space of the liner assembly 1, and the balance passage 411 is not communicated with the inner space of the liner assembly 1, so that the fan 42 can supply air into the liner assembly 1.

Further, as shown in fig. 24, the body 41 may further have a communication channel 414 therein, the top surface of the communication channel 414 is in communication with the balancing channel 411, and the side surface of the communication channel 414 is in communication with the air supply channel 413, the reversing structure 43 is a partition plate provided in the communication channel 414, and the upper end of the partition plate is hinged to the top of the air supply channel 413, such that the partition plate can rotate around the hinge position, the reversing structure 43 closes the inlet of the balancing channel 411 in the second state, the partition plate closes the outlet of the air supply channel 413 in the first state, and the reversing structure 43 is inclined in the air outlet direction (e.g., the direction from right to left in fig. 24) of the air supply channel 413 in the top-to-bottom direction.

When the fan 42 is operated, the fan 42 may supply air into the air supply channel 413, and because the partition is hinged and the partition is inclined along the air outlet direction of the air supply channel 413, the fan 42 may easily blow the partition, so that the partition separates the communication channel 414 from the balance channel 411, and at this time, the air supply channel 413 is communicated with the communication channel 414, and the fan 42 may supply air into the liner assembly 1 through the air supply channel 413, the communication channel 414, and the liner air inlet 102.
