A micro-piezo electric steamer rapid pressure relief and cooling device

Abstract

A micro-piezoelectric steaming box rapid pressure relief and cooling device, comprising a water tank, a steam generator and an inner tank, is characterized in that it also includes a spray cooling water tank, a steam channel is arranged between the inner tank and the spray cooling water tank, and the water tank is provided with a steam channel. The water flows into the spray cooling water tank through the first water flow channel for spray cooling, and the steam condensed water and spray cooling water in the spray cooling water tank return to the water tank through the second water flow channel. The advantages of the present invention are: 1. When the steam volume remains unchanged, the volume of the container is suddenly increased to reduce the steam density, and the temperature of the inner tank can be quickly lowered; Clean; 3. The spray water does not pass through the inner tank, which can ensure that the water quality of the return water tank is relatively clean, and the water can be reused; Save water; 5. The amount of steam in the inner tank can be reduced in advance to avoid excessive steam overflow when opening the door to scald the user.

Description

technical field [0001] The invention relates to an electric steamer, in particular to a rapid pressure relief and cooling device for a micro-piezo electric steamer. Background technique [0002] Under normal operation of the micro piezoelectric steamer, the inner cavity pressure exceeds the standard atmospheric pressure, so the inner cavity temperature is also higher than 100°C; before the steamer stops working and the door is opened, it is necessary to reduce the inner cavity temperature and steam volume to ensure safety. There are two main cooling methods for traditional pressure cooking equipment: one is to directly discharge steam to the outside to reduce the steam density to lower the inner cavity temperature, and the other is to spray cold water to the inner cavity to lower the inner cavity temperature. Although the above two methods can reduce the temperature of the inner cavity, they also have their own shortcomings. The disadvantage of direct steam discharge is a wa...

AI Technical Summary

Problems solved by technology

The pressure relief structure of the above-mentioned electric steamer only discharges the steam in the inner tank through the steam outlet or the pressure relief port, but cannot quickly reduce the temperature of the steam in the inner tank, and the direct discharge of steam not only poses a safety hazard, but also is not conducive to water recycling
