The PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant-temperature and electricity-saving electric heater. The safety device has the outstanding characteristics that the surface of an electric heating tube heater does not turn red under any application condition on the safety performance, so that potential safety hazards such as scalding and fire disasters are prevented.

In some embodiments, the dishwasher 100 further includes a water receiving portion 60, the water receiving portion 60 is disposed on the bottom wall of the inner tub 10 and has a water collecting tank 61 communicating with the washing chamber 11, and the water container 52 is configured to be selectively communicated with or disconnected from the water collecting tank 61. Thus, the water receiving part 60 is disposed on the bottom wall of the inner container 10, and the water collecting tank 61 is formed in the water receiving part 60, the water collecting tank 61 is equivalent to the lowest point of the inner container 10, when residual water is collected in the inner container 10, the residual water can be collected in the water collecting tank 61 under the action of self gravity, and the water collecting tank 61 can be selectively switched on and off with the water containing piece 52, when the water collecting tank 61 is communicated with the water containing piece 52, the residual water in the water collecting tank 61 can flow into the water containing piece 52, and is evaporated to flow to the outside of the dishwasher 100 under the action of hot air blown out by the drying component 54. In other words, the residual water in the washing chamber 11 is collected by the pen and then is uniformly introduced into the water container 52 for evaporation.

Further, the dishwasher 100 further includes a valve 62, the water receiving portion 60 and the water container 52 are communicated with each other by a communication line, the valve 62 is disposed on the communication line, and the valve 62 is configured to selectively close and open the communication line, so that the water receiving portion 60 and the water container 52 can be connected and disconnected by switching the state of the valve 62. When the dishwasher 100 is performing a washing operation, the valve 62 is closed, and the washing water is sprayed through the spray arm 20 to clean the dishes in the basket. When the residual water removing operation is started, the valve 62 is opened to allow the residual water in the water receiving part 60 to flow to the water containing member 52, and then the residual water is dried.

Further, the dishwasher 100 further includes a washing pump 72 and a drainage assembly 74, the washing pump 72 is disposed on a pipeline between the water receiving portion 60 and the spray arm 20, and the washing pump 72 is used for driving liquid to enter the spray arm 20 from the water receiving portion 60 and circularly supply water to the spray arm 20; the drain assembly 74 is connected to the water receiving portion 60, and is used to drain the liquid in the water receiving portion 60. When the dishwasher 100 starts a washing operation, a water supply pipe externally connected to the dishwasher 100 communicates with the spray arm 20 to supply washing water to the spray arm 20, and after a certain period of time, the water supply pipe stops supplying water, and the washing pump 72 is turned on to re-supply the washing water, which has been sprayed into the washing chamber 11, to the spray arm 20 to continue spraying the washing water.

Equivalently, a part of the drain pipe 75 is bent into an inverted U shape to form the anti-backflow section 76, and after the drain pump 77 drives the washing water to flow through the anti-backflow section 76, the washing water cannot flow backwards into the washing cavity 11 through the convexly arranged anti-backflow section 76, so that a better drainage effect is achieved.

Specifically, in the present embodiment, one end of the water container 52 along the arrangement direction of the plurality of sub water containing cavities 512 is selectively communicated with the water receiving portion 60, and the other end of the water container 52 along the arrangement direction of the plurality of sub water containing cavities 512 is communicated with the drying assembly 54, when hot air is generated by the drying assembly 54, the hot air can flow through each sub water containing cavity 512, and after the steam formed by evaporation in each sub water containing cavity 512 is brought into the washing cavity 11 of the inner container 10, the steam is discharged out of the dishwasher 100 along with the steam attached to the dishes. Thus, the hot air generated by the drying assembly 54 can dry and evaporate the residual water in the water container 52, and simultaneously can pass through the washing chamber 11 of the inner container 10, and can dry the tableware in the washing chamber 11, so as to prevent the residual water from being formed again due to the water vapor accumulated in the washing chamber 11.

It is understood that in other embodiments, one end of the water container 52 along the arrangement direction of the plurality of sub water containers 512 is connected to the drying assembly 54, and the other end of the water container 52 along the arrangement direction of the plurality of sub water containers 512 is not only selectively connected to or disconnected from the water receiving portion 60, but also provided with an air outlet. When the dishwasher 100 removes the residual water, the water containing member 52 is disconnected from the water receiving portion 60, the hot air formed by the drying component 54 flows out from the air outlet after passing through the plurality of sub water containing cavities 512, and the water vapor formed by evaporation in the sub water containing cavities 512 is directly brought to the outside through the air outlet without passing through the washing cavity 11 of the inner container 10, so that the air outlet stroke is shortened, and the drying efficiency is improved.

In addition, when the tableware is stored in the inner container 10 for a long time, the condensed water of the inner container 10 and the tableware drops into the inner container 10 and the water receiving part 60, and the washing and excavating machine is started to remove the residual water at regular time in order to prevent the condensed water from polluting the washing cavity 11 again. Specifically, the dishwasher 100 further comprises a controller and a detector, wherein the detector is used for detecting whether tableware is stored in the washing chamber 11, when the length of time for storing the tableware in the washing chamber 11 reaches a preset length of time, the controller regularly opens the residual water removing function according to the preset interval length of time, namely, the valve 62 and the drying component 54 are opened, the residual water formed by condensation of the inner container 10 and the tableware is regularly dried, the inner container 10 and the tableware are kept dry for a long time, and bacterial growth is inhibited.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
