Steam discharge structure

Abstract

The invention relates to a steam discharge structure. The steam discharge structure comprises an inner container with a steam inlet and a steam outlet, and further comprises a condensation cavity withan air inlet and an air outlet, wherein the air inlet is in fluid communication with the steam outlet; and a pressure one-way valve is arranged on the air outlet. Compared with the prior art, steam in the inner container is not directly discharged through an air exhaust passage, instead, the steam enters the condensation cavity; a condenser is equivalent to a steam overshoot buffer area of the inner container; and when a small amount of the steam in the inner container is subjected to hedging, the excessive steam enters the condensation cavity through the steam outlet, so that the balance ofthe internal pressure of the inner container and the temperature field is effectively achieved. In addition, after the steam in the inner container enters the condensation cavity, only when the internal pressure in the condensation cavity reaches a preset pressure value (that is, the pressure required for opening the pressure one-way valve) of the pressure one-way valve, the pressure one-way valvecan be opened for exhausting the steam, so that the excessive steam can be effectively prevented from being discharged to outside and the excessive heat loss is avoided.

Description

technical field [0001] The invention relates to the field of electric steamers, in particular to a steam discharge structure. Background technique [0002] In recent years, the proportion of steamed dishes in people's diet has gradually increased, because the steamed cooking method is more nutritious and healthy, and the steamed food is easier to digest, suitable for the elderly and children. The steam of the existing electric steamer is generally generated by heating a certain amount of water through heat conduction, and the mechanism of steam generation determines that the amount of steam entering the inner container through the inlet port of the inner container is uncontrollable. At present, electric steamers generally introduce steam directly into the exhaust duct, and reduce the temperature and humidity of the steam by mixing with the cold air in the exhaust duct. Although the above method can reduce the temperature and humidity of the steam discharged from the inner t...

AI Technical Summary

Problems solved by technology

Although the above method can reduce the temperature and humidity of the steam discharged from the inner tank, but because the inner tank and the exhaust duct are almost straight through, the steam discharge is still large and the heat loss is relatively large

In addition, this way of evacuation will also affect the uniformity of the temperature field of the inner tank
