Steam liquefaction recovery device

Abstract

The invention discloses a steam liquefaction recovery device, which comprises a water tank, a first water pump, a water storage box, a heat exchange device, a second water pump, a third water pump anda cavity, wherein a controller controls the first water pump, the second water pump, the third water pump, an evaporator and a water level monitoring probe to work, the first water pump pumps water in the water tank into the water storage box, the water level monitoring probe is arranged on the water storage box, the second water pump pumps water in the water storage box into the evaporator, high-temperature steam generated by the evaporator can be conveyed into the cavity, a temperature sensor is arranged at the bottom of the evaporator, the third water pump pumps water in the water storagebox into the heat exchange device through the first inlet of the heat exchange device, the first outlet of the heat exchange device is communicated with the water storage box, the gas outlet in the top of the cavity is communicated with the second inlet of the heat exchange device, and the second outlet of the heat exchange device is communicated with the water storage box. According to the invention, water at the front end of the evaporator can be preheated through heat released by steam thermal liquefaction in the steam condensation system, so that the effects of increasing the steam speed and saving energy are achieved.

Description

Technical field [0001] The invention belongs to the technical field of kitchen appliances, and in particular relates to a steam discharge recovery device with steam function, such as a steamer and a steamer. Background technique [0002] Steaming boxes, steaming ovens and other products that use steam to cook food. In order to avoid the problem of excessive pressure in the cavity caused by the continuous increase of steam during use, the prior art has provided steam outlets on the inner tank to reduce pressure and maintain The pressure inside and outside the cavity is balanced, and the steam in the cavity is discharged from the front of the machine under the action of the fan through the exhaust port: 1. High temperature and high humidity steam will have a certain impact on the kitchen environment. In winter, the kitchen will be filled with steam, and the kitchen will be high in summer. High humidity and water vapor will also cause corrosion to the kitchen cabinets to a certain e...

Problems solved by technology

[0002] Steamers, steam ovens and other products that use steam to cook food, in order to avoid the problem of excessive pressure in the cavity caused by the continuous increase of steam volume during use, the existing technology is equipped with steam outlets on the inner tank to reduce pressure and maintain The pressure inside and outside the cavity is balanced, and the steam in the cavity is discharged from the front of the machine through the exhaust port under the action of the fan: 1. The high-temperature and high-humidity steam will have a certain impact on the kitchen environment. In winter, the kitchen will be full of steam, and in summer, it will cause high temperature in the kitchen High humidity and water vapor will also cause corrosion to the kitchen cabinets to a certain extent; 2. This method of directly discharging steam will not only cause a certain amount of waste of energy, but also the high-heat steam may burn the user if it is emitted to the outside world, thus 3. There is vibration and noise in the operation of the fan, and generally it still needs to run for a period of time after the work is over, which affects the user experience

At present, there is a transition cavity with a certain volume at the outlet of the exhaust steam to condense the steam and reduce the amount of exhaust steam. However, after a certain period of time, due to the temperature of the transition cavity surface, it is impossible to condense the steam, so it cannot Completely solve the existing problems
