[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model Embodiment 1
[0022] As shown in Figure 7 and Figure 8 , the present utility model discloses a multifunctional drainage plug. The technical solution adopted is that it includes a plug cover 101 and a plug pipe 102. The plug cover 101 is in the shape of a circular plate, and the plug pipe 102 is in the shape of a circular tube. The end face of the plug pipe 102 is connected to the end face of the plug cover 101, and the two are coaxially arranged. The edge of the plug cover 101 is connected to the sealing ring 103 through the connection section 104. The sealing ring 103 adopts an O-ring. While the plug cover 101, the plug pipe 102 and the connection section 104 are all made of silicone material to achieve a good sealing effect, the softness of the connection section 104 can facilitate the smooth bending of the plug cover 101, making the switching between the sealing and opening states of the drainage plug 1 more convenient
[0023] In order to further facilitate the opening of the plug cover 101, finger grooves 105 are provided at the edge of the plug cover 101. The finger grooves 105 are upward protrusions, in the shape of a tent. Inserting the fingers into the finger grooves 105 can lift the plug cover 101 upward. The setting of the finger grooves 105 enables the staff to apply force better. The sealing ring 103 is sleeved on the drain pipe 4 and is placed between the pipe edge 401 and the inner bottom surface 201
[0024] As shown in Figure 9 , a counterbore for accommodating the pipe edge 401 is provided on the inner bottom surface 201 of the cabinet 2 opposite to the pipe orifice of the drain pipe 4. The pipe edge 401 is located in the counterbore. There is a drainage port 3 on the cabinet 2, and the drain pipe 4 is inserted into the drainage port 3
[0025] When the above-mentioned drainage plug 1 is in use, the sealing ring 103 is placed between the pipe edge 401 and the bottom surface of the sunken hole on the inner bottom surface 201 to seal the joint. The plug pipe 102 is inserted into the drain pipe 4, and the plug cover 101 covers the upper opening of the pipe edge 401.
[0026] The working principle of the present utility model:
[0027] When assembling the refrigerator, the sealing ring 103 is sleeved on the drain pipe 4 and placed between the pipe edge 401 and the bottom surface of the sunken hole on the inner bottom surface 201. After the assembly is completed, the drainage plug 1 is used to block the drain pipe 4.
[0028] When it is necessary to discharge the defrosting water, insert the finger into the finger groove 105, lift the plug cover 101 upward to open the drain pipe 4. Due to the connection of the connecting section 104, the plug cover 101 and the plug pipe 102 will not be lost. After the discharge is completed, the plug pipe 102 is inserted into the drain pipe 4.
[0029] Due to the sealing of the sealing ring 103, the defrosting water will not seep into the foaming layer 202 from below the pipe edge 401.
[0030] The mechanical connection involved in the present utility model is a common means adopted by those skilled in the art and can obtain technical inspiration through a limited number of tests, which belongs to common general knowledge.
[0031] The components not described in detail in this article are prior art.
[0032] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
