For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0039] The dish washing machine generally uses water flow to wash the oil stains on the dishes, mainly using the impact force of the water flow to impact the oil stains on the dishes, so a large amount of water is needed to complete a washing, and if the water quantity is reduced, water can be saved, but the washing effect will also be affected.

[0040] The main reason for the above problems is that the impact force of the water flow is weakened when the water amount is insufficient, and the oil stains on the dishes are difficult to wash out.

[0041] The related art discloses a dish-washing machine spray arm and a spray type dish-washing machine, the top surface of the dish-washing machine spray arm is provided with a nozzle for spraying cleaning water, the bottom is provided with a water inlet pipe extending downward, the inner cavity of the water inlet pipe is provided with a speed-increasing water channel, the water area of the inner cavity of the water inlet pipe on the upper and lower sides of the speed-increasing water channel is greater than the water area of the speed-increasing water channel, the side wall of the water inlet pipe is provided with an air suction hole at a position above the speed-increasing water channel, and the flow rate of the water flow increases when the water flow passes through the speed-increasing water channel to suck external air into the water inlet pipe through the air suction hole. Since the water area of the speed-increasing water channel is smaller than the water area of the inner cavity of the water inlet pipe on the upper and lower sides of the speed-increasing water channel, the flow rate suddenly increases when the water flow enters the speed-increasing water channel, according to the Venturi principle, a negative pressure is formed on the upper side of the speed-increasing water channel, thereby external air is sucked in through the air suction hole to realize water-air mixing. The water-air mixing is realized by arranging the speed-increasing water channel and the air suction hole in the water inlet pipe, and the spraying pressure is increased by mixing air with cleaning water.

[0042] The related art above utilizes air to mix with cleaning water to increase the spraying pressure, but the proportion of air and cleaning water cannot be adjusted.

[0043] The embodiments of the present application are described below in combination with Figures 1 to 3 , the embodiments of the present application.

[0044] According to the embodiments of the present application, a dish-washing machine is provided, which comprises: an inner container 1, a mixing part 2, a water inlet pipe 3 and an air inlet pipe 5.

[0045] The mixing part 2 is in communication with the inner container 1; the water inlet pipe 3 is in communication with the mixing part 2, and the water inlet pipe 3 is provided with a first proportional valve 4; the air inlet pipe 5 is in communication with the mixing part 2, and the air inlet pipe 5 is provided with a second proportional valve 6.

[0046] In the embodiments, the water inlet pipe 3 is used for water inlet, the air inlet pipe 5 is used for air inlet, and the water inlet pipe 3 and the air inlet pipe 5 are both in communication with the mixing part 2, so that the water entering through the water inlet pipe 3 and the air entering through the air inlet pipe 5 are mixed in the mixing part 2 to form a water-air mixture, and then enter the inner container 1 to wash the tableware. Compared with washing with water alone, the impact force can be improved, so that the oil stain removal effect can be improved. In addition, by arranging the first proportional valve 4 on the water inlet pipe 3 and the second proportional valve 6 on the air inlet pipe 5, the proportion of water inlet and air inlet can be adjusted, so that different intensity tableware and tableware with different oil stain degrees can be washed, and the energy consumption is further reduced.

[0047] In one specific embodiment, for heavily soiled tableware, the opening of the first proportional valve 4 and the second proportional valve 6 can be increased to increase the water and air intake; for lightly soiled tableware, the water and air intake can be reduced, or the water intake can remain unchanged while the air intake is reduced.

[0048] In one specific embodiment, for heavily soiled tableware, the ratio of water intake to air intake is adjusted to 9:1 or 8:2 by adjusting the first proportional valve 4 and the second proportional valve 6.

[0049] In one specific embodiment, for lightly oily tableware, the ratio of water intake to air intake is adjusted to 6:4 or 7:3 by adjusting the first proportional valve 4 and the second proportional valve 6.

[0050] In one specific embodiment, for tableware made of relatively weak materials, the opening of the second proportional valve 6 can be appropriately reduced to decrease the air intake and reduce the impact force, thus better protecting the dishes.

[0051] In this embodiment, by adjusting the first proportional valve 4 and the second proportional valve 6, the water-air mixing energy can be adapted to various cleaning scenarios.

[0052] In one specific embodiment, as shown in the figure, the inner liner 1 is provided with a dish basket 11, and when the tableware needs to be washed, the tableware is placed in the dish basket 11.

[0053] like Figure 1 As shown, the inner liner 1 is equipped with a double-layered bowl basket 11.

[0054] In one embodiment, the dishwasher further includes a controller 10, which is communicatively connected to a first proportional valve 4 and a second proportional valve 6. The dishwasher has at least two washing modes, and the opening degree of the first proportional valve 4 and the second proportional valve 6 is different in different washing modes.

[0055] In this embodiment, a controller 10 is configured to communicate with the first proportional valve 4 and the second proportional valve 6. When the user selects a washing mode, the controller 10 can automatically adjust the opening degree of the first proportional valve 4 and the second proportional valve 6.

[0056] It should be noted that the controller 10 is communicatively connected to the first proportional valve 4 and the second proportional valve 6. Specifically, this can mean that the controller 10 is connected to the first proportional valve 4 and the second proportional valve 6 via a wired connection, or it can mean that the controller 10 is connected to the first proportional valve 4 and the second proportional valve 6 via a wireless connection, such as a Bluetooth connection or a Wi-Fi connection.

[0057] In one specific embodiment, when the user selects the heavy oil stain washing mode, the controller 10 controls the opening of the first proportional valve 4 and the second proportional valve 6 to adjust the ratio of water intake to air intake to 9:1 or 8:2.

[0058] It should be noted that, for example, when the ratio of water and air is required to be 9:1, the opening of the first proportional valve 4 is adjusted to 9 / 10, and the opening of the second proportional valve 6 is adjusted to 1 / 10.

[0059] For example, when the ratio of water and air is required to be 8:2, the opening of the first proportional valve 4 is adjusted to 8 / 10, and the opening of the second proportional valve 6 is adjusted to 2 / 10.

[0060] Specifically, in an embodiment, when the user selects a light oil stain washing mode, the controller 10 controls the opening of the first proportional valve 4 and the second proportional valve 6 to be adjusted, so that the ratio of water and air is 6:4 or 7:3.

[0061] Specifically, for example, when the ratio of water and air is required to be 6:4, the opening of the first proportional valve 4 is adjusted to 6 / 10, and the opening of the second proportional valve 6 is adjusted to 4 / 10.

[0062] For example, when the ratio of water and air is required to be 7:3, the opening of the first proportional valve 4 is adjusted to 7 / 10, and the opening of the second proportional valve 6 is adjusted to 3 / 10.

[0063] In other alternative embodiments, the user can manually adjust the opening of the first proportional valve 4 and the second proportional valve 6.

[0064] In an embodiment, the water inlet pipe 3 is also provided with a water pump 7.

[0065] In this embodiment, by providing the water pump 7 on the water inlet pipe 3, the water pump 7 can pressurize the water flow, ensure that the water can enter the inner container 1, and improve the cleaning effect.

[0066] Specifically, in an embodiment, one end of the water inlet pipe 3 is connected with the mixing part 2, and the other end can be connected with a water softener.

[0067] Specifically, in an embodiment, one end of the water inlet pipe 3 is connected with the mixing part 2, and the other end can be connected with a water source.

[0068] In an embodiment, the air inlet pipe 5 is connected with an air source at the end away from the mixing part 2.

[0069] In this embodiment, the air inlet pipe 5 is connected with an air source at the end away from the mixing part 2, the air source is used to provide compressed air, the water entering through the water inlet pipe 3 and the compressed air entering through the air inlet pipe 5 are mixed in the mixing part 2 to form a water-air mixture, and then enter the inner container 1 to wash the tableware. Compared with washing with water alone, the impact force can be improved, and therefore the oil stain removal effect can be improved.

[0070] In an embodiment, the air source is an air pump 8.

[0071] In this embodiment, the air source is an air pump 8, which directly provides compressed air. Water entering through the water inlet pipe 3 and compressed air entering through the air inlet pipe 5 are mixed in the mixing section 2 to form a water-air mixture, which then enters the inner liner 1 to rinse the tableware. Compared with rinsing with water alone, this can increase the impact force and thus improve the degreasing effect.

[0072] Specifically, such as Figure 2 As shown, one end of the air intake pipe 5 is connected to the mixing section 2, and the other end is equipped with an air pump 8. The air intake pipe 5 is equipped with a second proportional valve 6.

[0073] In one specific embodiment, the mixing section 2 is a pipe that is connected to the air inlet pipe 5 and the water inlet pipe 3 via a tee.

[0074] In one embodiment not shown in the figure, the air source can be an air tank containing compressed air. The compressed air in the air tank enters the mixing section 2 through the air inlet pipe 5 and mixes with the water entering through the water inlet pipe 3 to form a water-air mixture, which then enters the inner liner 1 to rinse the tableware.

[0075] In one embodiment, the mixing section 2, the water inlet pipe 3, and the air inlet pipe 5 are all located at the bottom of the inner liner 1.

[0076] In this embodiment, the mixing section 2, the water inlet pipe 3, and the air inlet pipe 5 are all located at the bottom of the inner liner 1, which can make full use of the space at the bottom of the inner liner 1.

[0077] In one embodiment, the controller 10 is located at the bottom of the inner liner 1.

[0078] In this embodiment, the controller 10, mixing unit 2, water inlet pipe 3 and air inlet pipe 5 are all located at the bottom of the inner liner 1. On the one hand, the space at the bottom of the inner liner 1 can be fully utilized. On the other hand, the controller 10 is close to the first proportional valve 4 and the second proportional valve 6, which facilitates the electrical connection between the controller 10 and the first proportional valve 4 and the second proportional valve 6.

[0079] In one embodiment, the inner liner 1 is provided with a spray arm 9, which is connected to the mixing section 2.

[0080] In this embodiment, the water inlet pipe 3 is used for water inlet, the air inlet pipe 5 is used for air inlet, the water inlet pipe 3 and the air inlet pipe 5 are both communicated with the mixing part 2, thus the water entering through the water inlet pipe 3 and the air entering through the air inlet pipe 5 are mixed in the mixing part 2 to form a water-air mixture, and then enter the spray arm 9, and are sprayed out of the spray arm 9 to wash the tableware, compared with washing with water alone, the impact force can be improved, thus the oil stain removal effect can be improved. In addition, by arranging the first proportional valve 4 on the water inlet pipe 3 and the second proportional valve 6 on the air inlet pipe 5, the proportion of water inlet and air inlet can be adjusted, thus the washing of tableware with different strength and tableware with different oil stain degree can be met, and the energy saving is better.

[0081] In one embodiment, the spray arm 9 is close to the bottom wall of the inner container 1.

[0082] In this embodiment, since the spray arm 9 is close to the bottom of the inner container 1, the distance between the spray arm 9 and the mixing part 2 can be reduced, and the communication between the mixing part 2 and the spray arm 9 is facilitated.

[0083] Specifically, in one embodiment, the spray arm can be rotatably arranged in the inner container 1, and the water-air mixture is washed in all directions without dead angle through the nozzles on the spray arm. The spray arm is usually designed to rotate 360 degrees to ensure that the water flow can cover every corner in the dishwasher, thereby effectively cleaning the residues and oil on the tableware.

[0084] Specifically, the spray arm can be driven to rotate under the reaction force of the water flow, and a plurality of water injection holes are designed on the spray arm. When high-pressure water flow is sprayed out of these holes, a reaction force is generated to push the spray arm to rotate. This design enables the water flow to cover the surface of the tableware in all directions, ensuring the cleaning effect.

[0085] Specifically, the spray arm can also be driven to rotate by a motor. The motor drives the spray arm to rotate at high speed through a transmission device, ensuring that the water flow can uniformly and efficiently wash every corner of the tableware.

[0086] The spray arm is usually designed as a double-arm or multi-arm structure, and the angle of the water injection holes is carefully designed to achieve multi-angle water injection during rotation. This design enables the water flow to cover the difficult-to-clean parts of the tableware, such as recesses, inner sides and bottoms.

[0087] Specifically, in one embodiment, the working process of the dishwasher is as shown in the following table: Figure 3 The dishwasher starts to work - selects the washing mode - the water pump 7 and the air pump 8 run at the same time - the controller 10 adjusts the first proportional valve 4 and the second proportional valve 6 to adjust the output proportion of water and air according to the washing mode - the water-air mixture is sprayed out of the spray arm 9 to wash - the whole water-air mixing washing mode is completed.

[0088] Specifically, the dishwasher provided in this embodiment can be divided into the following processes during the cleaning process:

[0089] Pre-washing stage: high pressure water flow through the spray arm to the tableware cycle washing, washing off most of the residue, and then sewage discharge, in the process, can be adjusted according to the actual situation of the first proportional valve 4 and the second proportional valve 6 opening, alone using water or water gas mixture to tableware cycle washing.

[0090] Main washing stage: high pressure water flow through the heating device heating, while the detergent into the water, through the spray arm cycle washing tableware, sewage discharge, in the process, can also be adjusted according to the actual situation of the first proportional valve 4 and the second proportional valve 6 opening, alone using water or water gas mixture to tableware cycle washing, in addition, the water inlet pipe 3 and heating component communication, heating component after heating water through the water inlet pipe 3 into the mixing part 2.

[0091] Rinse stage: using cold water to tableware rinse, ensure that the detergent and residual dirt is removed. In the process, can also be adjusted according to the actual situation of the first proportional valve 4 and the second proportional valve 6 opening, alone using water or water gas mixture to tableware rinse.

[0092] Drying stage: in the water to add brightener, water temperature heating to 70 DEG C, through the spray arm washing and then discharge, using drying system fast drying tableware.

[0093] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, such modifications and changes fall within the scope defined by the present application.
