The first embodiment of the present application:

as shown in fig. 1, the present embodiment provides a dishwasher including a body 1, a spray arm 2 as a spray member, and a transfer pump 3. The machine body 1 is provided with a washing cavity, the spray arm 2 is arranged in the washing cavity, and the delivery pump 3 can selectively deliver liquid or gas to the spray arm 2, so that the spray arm 2 can spray liquid or wind into the washing cavity. When the washing machine is used, a user firstly places tableware to be washed in the washing cavity, then the conveying pump 3 receives liquid and conveys the liquid to the spraying arm 2, and the spraying arm 2 sprays the liquid into the washing cavity, so that the tableware is washed. After the washing is finished, the liquid supply to the transfer pump 3 is stopped, the transfer pump 3 transfers the gas to the spray arm 2, the spray arm 2 sprays the gas into the washing chamber, and the gas flow is utilized to accelerate the evaporation of water, thereby drying the tableware. With the dishwasher provided by the embodiment, the delivery pump 3 can receive liquid and deliver the liquid to the spray arm 2, the spray arm 2 sprays the liquid to complete washing, the delivery pump 3 can also deliver gas to the spray arm 2, and the spray arm 2 sprays the gas to complete drying. Therefore, by applying the dishwasher of the embodiment, the delivery pump 3 and the spray arm 2 can complete both the washing function and the drying function, and drying systems such as an air inlet and a fan for drying do not need to be additionally arranged in the machine body 1, so that the structure of the dishwasher is simplified, the space of the dishwasher is saved, and the cost is saved.

The components of the present embodiment are further described in detail below:

delivery pump 3 in this embodiment:

as shown in fig. 1, the feed pump 3 includes a motor (not shown), a pump housing 4, and an impeller 5 disposed inside the pump housing 4.

As shown in fig. 1, the pump housing 4 is provided with a discharge port 41 and a suction port 42. The suction inlet 42 is used to receive liquid (which may be tap water, detergent dissolved liquid, etc.) when washing dishes, and to receive gas when drying dishes. The discharge port 41 communicates with the shower arm 2, and supplies liquid to the shower arm 2 during washing and gas to the shower arm 2 during drying.

As shown in fig. 3, the impeller 5 includes a support frame 51 and blades 52. The support frame 51 is a flat plate, the impeller 5 is provided with four blades 52 which are distributed at equal intervals, the blades 52 are of a flat plate structure, and the blades 52 are perpendicular to the support frame 51. Specifically, the plane of maximum area of each blade 52 is perpendicular to the tangent to the direction of rotation of the impeller 5. The support frame 51 may have an inclined surface. The blade 52 may be fixedly connected to the support frame 51, or may be integrally formed with the support frame 51. With continued reference to fig. 3, the support 51 is also provided with a through hole 8, through which hole 8 the nut 7 can pass.

As shown in fig. 2, the nut 7 is screwed on the rotating shaft 6 of the motor after passing through the through hole 8. It should be noted that the through hole 8 can be configured to be a special-shaped hole, the nut 7 is configured to be a special-shaped nut matched with the special-shaped hole, and the special-shaped nut is matched with the special-shaped hole, so that the nut and the impeller are not easy to rotate relatively.

When the device works, the motor drives the impeller 5 to rotate through the rotating shaft 6. When the tableware is required to be washed, the liquid supply to the conveying pump 3 is started, the liquid enters the pump shell from the suction port 42, and the centrifugal force generated by the rotation of the impeller 5 forces the liquid to be conveyed to the spray arm 2 through the discharge port 41. When drying is required, the supply of liquid to the transfer pump 3 is stopped, and the impeller 5 continues to rotate. Because the plane with the largest area of each blade 52 is perpendicular to the tangent of the rotation direction of the impeller 5, the blades 52 can play a role in conveying gas to the spray arm 2 in the rotation process.

It will be appreciated by those skilled in the art that the plane of maximum area of the vanes 52 may be at an angle other than substantially perpendicular to the tangent to the direction of rotation of the impeller 5, and that such a configuration may also serve to transport the gas. But vertically, the effect of the vanes 52 in delivering gas is best.

As shown in fig. 4, the pump housing 4 of the present embodiment is further provided with a heating pipe 9 as a heating means, a packing 10, and a mounting hole 11. The heater tube 9 is mounted in the pump housing 4 through the mounting hole 11 and sealingly abuts against the side wall of the mounting hole 11 by means of a sealing ring 10. Through setting up heating pipe 9, gas and liquid can be heated at the in-process that flows to discharge port 41, and the washing effect of the greasy dirt on the liquid to the tableware that has heated is better, and the drying action of the gas that has heated is better, can accelerate the drying. The heating pipe 9 is installed through the installation hole 11, so that the installation is convenient, and meanwhile, the replacement is convenient. The seal ring 10 can prevent leakage of gas and liquid.

It should be noted that the structure of the heating pipe 9 and the mounting hole 11 shown in fig. 4 is only one way of heating the device. In this embodiment, the heating device of electromagnetic heating type may be used or the heating device may be directly disposed on the inner wall of the machine body 1 to achieve the function of heating the gas.

In addition, the rotational speed at which the delivery pump 3 delivers liquid may not be suitable for delivering gas because the characteristics of liquid and gas are different. In the present embodiment, the feed pump 3 is configured to adjust the rotation speed of the impeller 5 in order to achieve a good feeding effect of the feed pump 3 on both the liquid and the gas. The rotating speed of the impeller 5 when conveying liquid is smaller than that of the impeller 5 when conveying gas, so that the conveying pump 3 can convey liquid with high viscosity at low rotating speed and gas with low viscosity at high rotating speed, the cleaning and drying effects on tableware are guaranteed, and energy waste caused by high rotating speed in two working modes is avoided.

This exampleSpray arm 2 in (2):

as shown in fig. 5, the shower arm 2 is provided with an inlet 21, a top injection hole 22, a bottom injection hole 23, and a communication passage 25. The inlet 21 communicates with the discharge port 41 of the pump housing 4, and the communication passage 25 communicates the inlet 21 with the top injection hole 22 and the bottom injection hole 23. When washing is required, the transfer pump 3 transfers the liquid into the communication passage 25 through the discharge port 41 and the inlet 21, and then the liquid is sprayed from the top spray holes 22 and the bottom spray holes 23 to wash dishes in the washing chamber. When drying is required, the transfer pump 3 transfers gas into the communication passage 25 through the discharge port 41 and the inlet 21, and then the gas is ejected from the top and bottom ejection holes 22 and 23 to dry the dishes in the washing chamber.

Specifically, as shown in fig. 6, the opening direction of the top spraying hole 22 of the spraying arm 2 has a certain angle, so that when the top spraying hole 22 sprays liquid or gas, the sprayed liquid or gas can provide a reaction force to the spraying arm 2, and the spraying arm 2 is pushed to rotate by the reaction force, so that the spraying arm 2 rotates in operation, further the tableware is sprayed in an all-directional manner, and the situation that the local part of the tableware cannot be cleaned or is stained with water is avoided. The above-described configuration may be realized by inclined ejection holes formed in the shower arm 2, or by mounting inclined nozzles to the ejection holes.

As shown in fig. 6, the hole opening direction of the bottom injection hole 23 is parallel to the tangent line when the spray arm 2 rotates, so that when the bottom injection hole 23 sprays liquid or sprays air, a reaction force for pushing the spray arm 2 to rotate can be provided, and the spray arm 2 can rotate more easily.

As shown in fig. 5, the communication passage 25 is provided with an inclined bottom wall 24, the inclined bottom wall 24 is inclined downward from the rotation axis of the shower arm 2 to the end of the shower arm 2, the bottom injection holes 23 are distributed at both ends of the shower arm 2 in a central symmetry manner with the rotation axis of the shower arm 2 as the center, and the bottom injection holes 23 are located at the lowest position of the communication passage. When the washing operation is completed, the residual liquid in the communicating channel 25 will flow along the inclined bottom wall and then flow out from the bottom spraying hole 23. By providing the inclined bottom wall 24, the residual liquid in the communicating channel 25 can be reduced, thereby preventing the residual liquid in the communicating channel 25 from being brought into the washing chamber by the air during the air blast to weaken the drying effect of the air.

In addition, it should be noted that the spray arm 2 in the present embodiment is only one form of the spray member, and a circular or elliptical spray plate may be adopted as required by those skilled in the art.

In this embodiment, the dishwasher further includes a cooling plate provided in the body 1. The cooling plate can condense water vapor in the gas into water, so that the moisture carried by the gas is reduced, the gas flowing in the washing cavity is drier, and the drying of the washing cavity and the tableware is accelerated.

Second embodiment of the present application:

as shown in fig. 7, unlike the first embodiment, in the present embodiment, the impeller 5 has six flat plate-like blades 52, and the six blades 52 are distributed on the support frame 52 at equal intervals.

It should be noted that the number of the vanes 52 is not limited to four and six in the foregoing embodiment, and other numbers of vanes may be used as long as the function of the vanes 52 for transporting gas is satisfied. Meanwhile, the plurality of blades 52 may be distributed at equal intervals or may be distributed at unequal intervals.

Third embodiment of the present application:

as shown in fig. 8, unlike the first and second embodiments, in the present embodiment, the blades 52 of the impeller 5 have an arc-shaped plate structure.

It should be noted that, on the premise of satisfying the function of the blade 52 for conveying gas, the structure of the blade 52 is not limited to the flat plate structure and the arc plate structure in the foregoing embodiments, and may be a wave-shaped plate structure as long as the blade 52 has a sufficient windward side.

So far, the technical solutions of the present application have been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of protection of the present application is not limited to these specific embodiments. The technical solutions in the above embodiments can be split and combined, and equivalent changes or substitutions can be made on related technical features by those skilled in the art without departing from the technical principles of the present application, and any changes, equivalents, improvements, and the like made within the technical concept and/or technical principles of the present application will fall within the protection scope of the present application.
