Household electric steam boiler

Abstract

The invention discloses a household electric steam boiler comprising a boiler body (1), a steam generator, a water tank (2) and a water feed mechanism. The steam generator comprises an electric heating disc (3). The water feed mechanism comprises a water supply pipe (4) and further comprises an internally penetrating connector (5). The connector (5) is provided with at least one water inlet pipe (5.1), at least one water outlet pipe (5.2), at least one gas inlet pipe (5.3) communicated with the atmosphere, and at least one gas return pipe. The horizontal plane height of the top of the inner wall of the joint between the gas return pipe and the gas inlet pipe (5.3) is greater than or equal to that of the top of the inner wall of the water outlet end of the water supply pipe (4). The household electric steam boiler is automatically fed with water by means of atmosphere, so that the water feed accuracy is high; besides, the boiler is simple in structure and low in cost; and the normal use of the electric steam boiler can be guaranteed.

Description

technical field [0001] The invention relates to a household appliance for cooking food indoors in homes, offices, business places, etc., in particular to a household electric steamer. Background technique [0002] The structure and working principle of the household electric steam oven in the prior art (similar in structure, there are also steam ovens, steamers, steam ovens, etc.) When the water in the water inlet pipe enters the electric heating plate of the steam generating device, high-temperature steam is generated, and food can be cooked by using the high-temperature steam. The water inlet pipe is connected to the water tank of the furnace body. The current water inlet mechanism generally has three structures: first, it is controlled by a solenoid valve, which is controlled by the controller to open at regular intervals. It is not supplemented according to the actual water volume in the electric heating plate. Sending water to the electric heating plate of the steam ge...

AI Technical Summary

Problems solved by technology

The water inlet pipe is connected to the water tank of the furnace body. The current water inlet mechanism generally has three structures: first, it is controlled by a solenoid valve, which is opened at regular intervals by the controller, and is not replenished according to the actual water volume in the electric heating plate. Water is sent to the electric heating plate of the steam generating device. The accuracy of the water inlet mechanism of this structure is poor; the second is to install a water detection sensor in the electric heating plate, and then connect the sensor to the controller, which has a complicated structure and high cost ; The third type, which is also the most commonly used, is to install a temperature sensor on the bottom surface of the electric heating plate. The flow rate of the incoming water is controlled by the electronic pump in the furnace body. The supply water of the electronic pump is determined by the temperature of the electric heating plate fed back by the temperature sensor. The controller of the household electric steamer controls, at this time, the temperature sensor activates the electronic pump through the controller to start supplying water to the electric heating plate. Malfunction, resulting in the electric steamer can not be used normally
