Sealing device for solving sealing safety problem of steam generator

Abstract

The invention relates to a sealing device for solving the sealing safety problem of a steam generator. The sealing device comprises a shell, a base and a thick film heating plate for separation in theshell, and the thick film heating plate divides the shell into a heating area and a non-heating area; and at least two sealing parts for sealing between the thick film heating plate and the shell arearranged in the shell, one sealing part is a second sealing ring arranged close to the edge of the thick film heating plate, and the other sealing part is a first sealing ring which wraps the edge ofthe thick film heating plate and abuts against the inner wall of the shell. According to the sealing device, the edges of the upper end face and the lower end face of the thick film heating disc arecompletely covered with second clamping grooves in the first sealing ring, water vapor is prevented from overflowing from the edge of the thick film heating disc, meanwhile, a storage area and the heating area are separated through the second sealing ring, and the situation that boiled water makes direct contact with the first sealing ring, and consequently the first sealing ring is aged and damaged is avoided; and a third sealing ring is arranged in a supporting table, so that water vapor in the storage area is prevented from making direct contact with a thick film circuit, and the circuit isprevented from being damaged.

Description

technical field [0001] The invention relates to the field of steam generator parts, in particular to a sealing device for solving the sealing safety problem of a steam generator. Background technique [0002] The steam generator is a mechanical device that uses the heat energy of fuel or other energy to heat water into hot water or steam. It came into being and is mainly used in washing machines, ovens and other household appliances; the miniaturized steam generator is small in size, which leads to excessive pressure in the steam generator shell. leakage, damage the circuit in the steam generator, and even cause damage to the casing in severe cases, causing hot water to splash and damage the user. Therefore, a sealing device for solving the sealing safety problem of the steam generator is designed to solve the above problems. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention proposes a sealing device for solving the se...

Problems solved by technology

[0002] The steam generator is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. It has a wide range of uses and is mainly used in restaurants, bathrooms, dry cleaners, garment factories, etc.; due to the development of technology, the miniaturization of steam generators Emerged as the times require, it is mainly used in washing machines, ovens and other household appliances; the small size of the steam generator causes the pressure inside the steam generator shell to be too high. If the seal between the heating element and the water storage chamber is not tight, it will easily lead to water vapor leakage, damage the circuit in the steam generator, and even cause damage to the shell in severe cases, resulting in splashing of hot water and damage to the user. Therefore, a sealing device is designed to solve the problem of sealing safety of the steam generator to solve the above problems
