Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a sealing structure for the soft water device cover of a dishwasher. Background Art

[0002] With the popularization of dishwashers in different countries and regions, more and more users have participated in the use of dishwashers. However, due to the different water quality hardness in different countries and regions, dishwashers are basically equipped with water softening devices, including the application of a soft water device as a functional component. The soft water device includes two major functional areas: a resin cavity and a cavity. The resin cavity is used to soften water, and the cavity is used to perform ion exchange on the resin in the resin cavity to reactivate the resin activity. However, the biggest problem with the current soft water device is the problem of brine leakage caused by the poor sealing of the soft water device cover. Most of the dishwasher cavities are made of stainless steel. Under the long-term corrosion of brine, rust will inevitably occur, which will not only affect the appearance of the dishwasher cavity, but even cause the dishwasher to leak due to rust corrosion and perforation.

[0003] Therefore, it is necessary to make further improvements. Summary of the Utility Model

[0020] The utility model will be further described below in conjunction with the drawings and embodiments.

[0021] See Figures 1 - 4, The sealing structure of the water softener cover of this dishwasher includes a water softener body 1 and a water softener cover assembly. The water softener cover assembly includes a water softener cover 2. A cavity 7 is provided inside the water softener body 1, and the cavity 7 is a salt cavity. The water softener cover assembly further includes a sealing ring 3. The sealing ring 3 is pressed between the water softener body 1 and the water softener cover 2. An elastic compression pack 4 is provided on the sealing ring 3. An air pressure cavity 5 is formed between the compression pack 4 and the water softener cover 2. The air pressure cavity 5 is a small air chamber space. An exhaust hole 6 communicating with the air pressure cavity 5 is provided on the water softener cover 2. The air pressure cavity 5 is connected to the external air pressure through the exhaust hole 6 to maintain balance. When the compression pack 4 is subjected to the internal pressure of the cavity 7, it elastically deforms upward to discharge the gas a in the air pressure cavity 5 to the outside through the exhaust hole 6; the air pressure cavity 5 is a buffer air pressure belt, which can reduce the impact of the internal pressure in the water softener salt cavity on the sealing surface, effectively reduce the risk of sealing failure of the water softener cover 2, and at the same time prevent the corrosion damage of the dishwasher cavity by the leaking salt brine 18, improving the use reliability of the dishwasher.

[0022] As Figure 1 shown, the compression pack 4 protrudes downward on the sealing ring 3, so that a recessed portion 8 is formed on the upper side of the sealing ring 3. The air pressure cavity 5 is formed between the recessed portion 8 and the inner side surface of the water softener cover 2.

[0023] As Figure 2 shown, after the compression pack 4 elastically deforms upward when subjected to the internal pressure of the cavity 7, the compression pack 4 protrudes upward on the sealing ring 3.

[0024] The cross-sectional shape of the compression pack 4 is arc-shaped, and the inner side surface shape of the water softener cover 2 is also arc-shaped. After the compression pack 4 elastically deforms upward when subjected to the internal pressure of the cavity 7, the compression pack 4 fits with the inner side surface of the water softener cover 2.

[0025] A sealing portion 9 is provided on the periphery of the sealing ring 3. A sealing pressure portion 10 is provided on the water softener body 1. The sealing pressure portion 10 is located around the top opening of the cavity 7. The sealing portion 9 is pressed between the sealing pressure portion 10 and the inner side surface of the water softener cover 2. A sealing surface for sealing the cavity 7 is formed between the sealing portion 9 and the sealing pressure portion 10. That is, the sealing ring 3 forms a seal through the local surface-to-surface tight pressing of the water softener cover 2 and the water softener body 1. The sealing surface is used to seal the gap between the water softener body 1 and the water softener cover 2, preventing the problem of rusting of the dishwasher cavity caused by salt leakage from the water softener.

[0026] A receiving groove 11 is provided on the inner side of the water softener cover 2, and the sealing ring 3 is arranged in the receiving groove 11.

[0027] An insertion portion 12 is provided at the top of the water softener body 1. The insertion portion 12 is located on the periphery of the cavity 7. The insertion portion 12 is inserted into the receiving groove 11, and the sealing pressure portion 10 is arranged at the top end of the insertion portion 12.

[0028] A buckle 13 is annularly arranged at the bottom of the accommodation groove 11, and a buckle position 14 is annularly arranged on the insertion part 12. The buckle 13 and the buckle position 14 are buckled with each other to fix the water softener cover 2 on the water softener body 1.

[0029] The dishwasher includes a breather 15. The breather 15 is connected to the water softener body 1 and is in communication with the cavity 7. A resin cavity is also arranged on the water softener body 1, and the breather 15 communicates with the resin cavity; specifically, several water outlet ports 16 are arranged on the breather 15, and several water inlet ports 17 are correspondingly arranged on the water softener body 1. The water outlet ports 16 are connected to the water inlet ports 17, and the breather 15 communicates with the salt cavity and the resin cavity through the corresponding water outlet ports 16 and water inlet ports 17 respectively; the regenerated water is sent into the salt cavity and the normal water is sent into the resin cavity through the breather 15 respectively.

[0030] During the process of sending the regenerated water into the water softener salt cavity through the breather 15, an internal pressure will be generated. For a water softener without elastic buffer pressure (i.e., the elastic compression package 4), it will directly impact the weakest sealing surface, resulting in poor sealing of the water softener; while adding a water softener cover assembly with elastic buffer (i.e., the elastic compression package 4), when the internal pressure suddenly generated in the water softener salt cavity is received, it will be reversely stressed through the elastic compression package 4 of the sealing ring 3. The compression package 4 elastically deforms upward to discharge the air pressure in the air pressure cavity 5 connected to the external air pressure, thereby reducing the pressure in the water softener salt cavity and further reducing the impact pressure on the sealing surface, thus greatly increasing the lasting reliability of the water softener seal and effectively avoiding the risk of salt leakage caused by poor sealing of the water softener cover assembly, and improving the reliability of the dishwasher.

[0031] The sealing ring 3 is made of rubber material.
