In the specific implementation process of the embodiment of the utility model, the sealing structure of the utility model is applied to the drainage assembly with one side being the cold cavity and the other side being the hot cavity, and in the practical use, as shown in fig. 3, the stress conditions of the sealing structure are mainly divided into the following three types:
1. when the drainage structure does not drain water into the sealing structure, namely the inside of the sealing structure in the application is in a dry state, the outflow part 20 of the sealing structure in the application is closed under the action of the self elastic force Ft;
2. when the drainage structure drains a trace amount of liquid into the sealing structure, namely the interior of the sealing structure in the application is slightly moist, the outflow part 20 of the sealing structure in the application is closed under the action of self-elasticity Ft and self-adsorption force of the liquid;
3. when the drainage structure drains liquid into the present seal structure, i.e. a certain amount of liquid is present inside the present seal structure, as shown in fig. 3, F1Force, F, acting on the inner wall of the seal for the liquid inside the seal in the present applicationxFor horizontal forces, F, acting on the inner wall of the seal for the liquid inside the seal in the present applicationxThe calculation formula is as follows:
Fx=G*sinθcosθ
in the above formula, θ — the slope between the inner walls of the seal structure of the present application; g-liquid self gravity.
In this case, the gravity G of the liquid itself can spread the closed portion of the outflow portion 20 to allow the liquid to pass therethrough. Specifically, when G × sin θ cos θ < Ft (Ft is the elastic force of the outflow portion 20 itself), the outflow portions 20 are still in the state of being bonded to each other. G × sin θ cos θ > Ft (Ft is the elastic force of the outflow portion 20 itself), the closed outflow portion 20 is opened under the pressure of the liquid, and the water flows therethrough.
In summary, when the inside of the seal structure of the present application is in a dry state or in a slightly wet state, the lower portions of the seal structure of the present application are bonded to each other. When a certain amount of liquid exists in the sealing structure in the application, the liquid acts on the inner wall of the sealing structure under the action of the gravity G of the liquid per se and the force F in the horizontal directionxWhen it is larger than its own elastic force Ft, the liquid, which moves toward the outflow port 201 at this time of the outflow part 20, is filled up and is opened by the pressure of the liquid to allow the water flow to pass.
In above-mentioned three kinds of circumstances, the air current all can't get into the seal structure in this application through outflow 20, and during the air current can't get into drainage assembly through this seal structure promptly, solved cold wind and scurried out and produced the problem of condensation water with hot-air through outlet 300, effectively prevented that the air conditioner from producing the potential safety hazard.
According to a second aspect of the present invention, as shown in fig. 4, there is provided a drain assembly comprising a water receiving tank 30 and a drain opening 300 communicating with the water receiving tank 30, the drain assembly further comprising: in the sealing structure 1, the inlet 10 of the sealing structure 1 is connected to the drain opening 300. Specifically, the sealing structure is applied to the drainage assembly with the cold chamber on one side and the hot chamber on one side, so that the cold air can be effectively prevented from flowing out from the drainage port 300 and generating condensed water with the hot air, and potential safety hazards are generated.
According to a third aspect of the present invention, as shown in fig. 4, there is provided an air conditioner including a drain opening 300, the air conditioner further including: in the sealing structure 1, the inlet 10 of the sealing structure 1 is connected to the drain opening 300.
