Steam generation assembly capable of achieving waste heat recovery and steam cooking device

Abstract

The invention discloses a steam generation assembly capable of achieving waste heat recovery. The steam generation assembly comprises a water tank and an evaporator, the water tank is connected with the evaporator through a water injection pipeline, the evaporator communicates with an inner container of cooking equipment through a steam inlet pipeline, the inner container of the cooking equipmentcommunicates with the water tank through a steam exhaust pipe, and a steam outlet pipe communicating with the exterior is further arranged on the water tank; and a water pump is arranged on the waterinjection pipeline. The invention further discloses a steam cooking device. Water absorbs waste heat in steam to enable the water temperature to be increased, thus the effect of preheating the water is realized, the preheated water enters the evaporator for heating and evaporating of steam, the steam generation time can be shortened, thus moisture in food is maintained, the nutrition loss is avoided, and the optimal effect of various steamed dishes is realized; and after the heat in the steam is absorbed by the water, condensed water is generated by part of the steam to enter the water, the utilization efficiency of the water is improved, after the rest part of the steam is exhausted, the situation that a cooker observes the cooking situation is not affected, and the cooker is prevented from being scalded.

Description

technical field [0001] The invention belongs to the technical field of cooking equipment, and in particular relates to a steam generating component for waste heat recovery and a steam cooking device. Background technique [0002] At present, the exhaust system of the electric steamer is generally composed of the inner tank of the electric steamer, the exhaust pipe, the upper and lower covers of the exhaust hood, and the cross-flow fan. An exhaust channel is formed. The exhaust hood opens an exhaust port on the upper part of the inner tank door of the electric steamer. The cross-flow fan at the rear discharges the steam from the exhaust pipe through the exhaust channel. When the user observes the cooking situation of the food during the cooking process, It is often blocked or scalded by the exhausted steam; and most of the current logic of adding water to the evaporator is given by the thermostat at the bottom of the evaporator. When the water in the evaporator is dried up, t...

[0002] At present, the exhaust system of the electric steamer is generally composed of the inner tank of the electric steamer, the exhaust pipe, the upper and lower covers of the exhaust hood, and the cross-flow fan. An exhaust channel is formed. The exhaust hood opens an exhaust port on the upper part of the inner tank door of the electric steamer. The cross-flow fan at the rear discharges the steam from the exhaust pipe through the exhaust channel. When the user observes the cooking situation of the food during the cooking process, It is often blocked or scalded by the exhausted steam; and most of the current logic of adding water to the evaporator is given by the thermostat at the bottom of the evaporator. When the water in the evaporator is dried up, the evaporator continues to heat up to the temperature set by the thermostat. , give an instruction to the water pump to add water to the evaporator. At this time, since the water at room temperature is added, the temperature of the heating tube of the evaporator will drop. The temperature fluctuates up and down, which increases the cooking time and causes the loss of moisture and nutrients in the food, which cannot achieve the best effect of all kinds of steamed vegetables.
