DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] This embodiment discloses a dishwasher, referring to Figure 1 , Figure 2 As shown, it comprises a washing chamber 1 and a spray arm 2 . The spray arm 2 is installed in the washing chamber 1 . The spray arm 2 can spray washing water into the washing chamber 1 to spray wash the dishes in the washing chamber 1 .

[0029] Reference Figure 3-Figure 5As shown, the spray arm 2 generally adopts a rotary spray arm structure, including an inner water pipe 21 and a spray member 22. The inner water pipe 21 plays a role of guiding water, and has a fluid inlet end 211 at the lower end of the inner water pipe 21. The spray member 22 adopts a horizontally arranged structure, and the middle end of the spray member 22 is rotatably connected to the inner water pipe 21. The spray member 22 is arranged with a plurality of spray holes, which can be connected with the fluid inlet end 211 of the inner water pipe 21. When the spray member 22 sprays outward, it can drive the spray member 22 to rotate, forming a rotating spraying state.

[0030] Reference Figure 6 , Figure 7 As shown, the dishwasher further includes an air supply component 3 and a one-way air guide 4. The air supply component 3 has an air outlet end 311, and the air outlet end 311 can output hot air to the outside.

[0031] The one-way flow guide 4 plays a role of one-way flow guidance, including a one-way inlet end 41 and a one-way outlet end 42, and the one-way inlet end 41 can flow one-way to the one-way outlet end 42. That is, in the one-way flow guide 4, the fluid can only flow one-way from the one-way inlet end 41 to the one-way outlet end 42, and cannot flow from the one-way outlet end 42 to the one-way inlet end 41. The one-way flow guide structure inside the one-way flow guide 4 can adopt a one-way valve structure in the prior art, which can achieve one-way flow guidance.

[0032] The one-way inlet end 41 of the one-way air guide 4 is connected to the air outlet end 311 of the air supply assembly 3 , and the one-way outlet end 42 is connected to the fluid inlet end 211 of the spray arm 2 .

[0033] In addition, the dishwasher further includes a liquid supply component, which has a liquid outlet end capable of supplying liquid, and the liquid outlet end is connected to the fluid inlet end 211. The fluid inlet end 211, the one-way outlet end 42 and the liquid outlet end can be connected by a three-way pipe, so that the liquid output by the liquid supply component and the airflow output by the air supply component 3 can be converged at the one-way outlet end 42, and the one-way outlet end 42 can be supplied in liquid or dried to obtain gas supply.

[0034] In the washing state, the liquid supply assembly supplies washing liquid to the fluid inlet end 211 of the spray arm 2. At the position of the fluid inlet end 211, the one-way flow guide 4 can play a role of preventing backflow, preventing the liquid from flowing back into the air supply assembly 3. In the drying state, the one-way flow guide 4 can communicate with the one-way flow guide, and the air outlet end 311 of the air supply assembly 3 can supply air to the fluid inlet end 211, and then spray out from the spray arm 2 to supply air into the washing chamber 1.

[0035] In the dishwasher, if the number of the spray arms 2 is one group, the one-way air guide 4 has a one-way outlet end 42 , which is connected to the fluid inlet end 211 of the spray arm 2 to supply air to the spray arm 2 .

[0036] In a dishwasher, if there are multiple groups of spray arms 2, the one-way flow guide 4 can play a role of diversion, that is, it can divide the input airflow into multiple streams and respectively pass them into multiple groups of spray arms 2, thereby achieving the effect of air supply at multiple positions in the washing chamber 1.

[0037] The one-way flow guide 4 includes at least two one-way outlet ends 42, and the number of the spray arms 2 is not less than the one-way outlet ends 42, and each one-way outlet end 42 is respectively connected to the fluid inlet end 211 of a spray arm 2. If each group of spray arms 2 is required to be able to play the role of air outlet, the number of one-way outlet ends 42 corresponds to the number of spray arms 2; or, if some spray arms 2 do not need to outlet air, the number of one-way outlet ends 42 can be less than the number of spray arms 2, and can be specifically selected according to the requirements of different dishwashers. For example, the number of spray arms 2 is three groups, and the three groups of spray arms 2 are distributed up and down, from top to bottom, they are upper spray arm 201, middle spray arm 202 and lower spray arm 203, the number of one-way outlet ends 42 is two, and the two one-way outlet ends 42 are respectively connected to the fluid inlet ends 211 of the upper spray arm 201 and the middle spray arm 202. The fluid inlet end 211 of the lower spray arm 203 is not connected to the one-way flow guide 4, and the lower spray arm 203 can only spray the detergent but not discharge air.

[0038] Generally, the one-way air guide 4 has a one-way inlet end 41, which is connected to the air outlet end 311 of the air supply assembly 3 through a conduit, and can supply air to the one-way air guide 4 and subsequent components. The one-way inlet end 41 can be unidirectionally conducted to each of the one-way outlet ends 42.

[0039] Alternatively, the one-way flow guide 4 may also be provided with a plurality of one-way inlet ports 41 (not shown in the figure), each of which is connected to a group of air supply components 3. A plurality of air supply components 3 simultaneously supply air to the one-way flow guide 4, and then can unidirectionally guide air to each one-way outlet port 42 to achieve air supply, thereby increasing the total air supply of the equipment.

[0040] Reference Figure 7 , Figure 8 As shown, the air supply assembly 3 includes an air duct 31, a fan 32 and a heating element 33, wherein the air duct 31 plays a role of guiding air, an air outlet 311 is arranged at the air duct 31, and an air inlet 313 is arranged at a position of the air duct 31 away from the air outlet 311. The fan 32 is installed at the air duct 31 and can be installed at a port of the air duct 31 or directly installed inside the air duct 31. Under the action of the fan 32, air can be supplied to the air outlet 311, and then the air can be discharged at the air outlet 311, and then the air can be supplied to the washing chamber 1.

[0041] The heating element 33 is installed in the air duct 31, and specifically a PTC electric heater can be used to generate heat to heat the air in the air duct 31. The heating element 33 cooperates with the fan 32 to form hot air in the air duct 31.

[0042] In addition, the air supply component 3 also includes a negative ion generator 34, which is installed in the air duct 31. The negative ion generator 34 can generate negative ions, and release negative ions during the air supply process, which can play a role in negative ion sterilization in the washing chamber 1, thereby playing a role in eliminating odor.

[0043] Specifically, the air supply assembly 3 can be installed on the outer side of the washing chamber 1, and the specific installation position can be arranged according to the design of the dishwasher. In the air supply assembly 3, the air outlet end 311 of the air duct 31 extends downward to the bottom of the washing chamber 1, and the air outlet end 311 will extend to a position close to the bottom of the washing chamber 1. The air outlet end 311 is connected to the one-way inlet end 41 of the one-way flow guide 4 through the air guide 312, thereby connecting the one-way flow guide 4 and the air supply assembly 3 to achieve the diversion supply of hot air.

[0044] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
