steam generator

Abstract

The invention relates to a steam generation device. The steam generation device comprises a heating body, wherein a vaporizing chamber is formed in the heating body. A water inlet channel and a steam discharging channel which both communicate with the vaporizing chamber are formed in the heating body. A magnetic valve is arranged on the water inlet channel. The magnetic valve comprises a valve seat and a valve element. One of the valve seat and the valve element is at least partially made of a permanent magnet material, and the other of the valve seat and the valve element is at least partially made of a material which can be attracted by the permanent magnet. The component at least partially made of the permanent magnet material is connected with the interior of the heating body or the vaporizing chamber in a heat transferring mode. The magnetic valve has a first working state and a second working state. When the magnetic valve is in the first working state, the component made of the permanent magnet material has the ferromagnetic property, the valve element is attracted onto the valve seat, and the water inlet channel is blocked; and when the magnetic valve is in the second working state, the component made of the permanent magnet material is paramagnetic, the valve element and the valve seat are separated, and the water inlet channel is unblocked. The valve body is controlled through the temperature to close and open, the structure is stable, action is reliable, water is supplied into a heater automatically without manual work, and stable steam is provided.

Description

technical field [0001] The present invention relates to a steam generating device, in particular to steam cleaning, steam ironing and other equipment for generating steam. Background technique [0002] The steam generating device is a necessary part of steam products. There is a type of device in the steam generating device that generates steam instantaneously, that is, the fast-heating steam generating device. A small amount of water is added to the chamber at a time, and after the small amount of water is converted into steam, a small amount of water is supplied to the vaporization chamber again. The advantage of this device is that it can quickly generate steam without waiting; the disadvantage of this device is that it requires manual control. The frequency of adding water, such as a steam mop disclosed in the Chinese Patent Publication No. CN101553157, a manual mechanical water pump in the mop transports the water in the water storage container to the digester (that is,...

Problems solved by technology

[0002] The steam generating device is a necessary part of steam products. One type of device in the steam generating device is a device that generates steam instantly, that is, a fast-heating steam generating device. Add a small amount of water to the chamber once, and then supply a small amount of water to the vaporization chamber after the small amount of water is converted into steam. The advantage of this device is that it can quickly generate steam without waiting; the disadvantage of this device is that it needs manual control. The frequency of adding water, such as the steam mop disclosed in the Chinese patent with the publication number CN101553157, a manual mechanical water pump in the mop delivers the water in the water storage container to the boiler (i.e. the steam generating device), and the mechanical water pump is The water pump is started by the movement of the mop to deliver water. Since the movement of the mop is completely dependent on the operation of the operator, it cannot achieve uniform movement, so the working frequency and force of the water pump are uncertain, which will lead to uncontrollable delivery to the digester. Therefore, the quality of the steam escaping from the boiler is very unstable, which affects the use of the steam mop; there are also some typical steam generating devices that use electric water pumps to boil the water in the water storage In the device, the on / off switch of the electric water pump is completely operated by the operator of the cleaning equipment, so there is also the problem of unstable steam output caused by untimely water delivery or too much water added at a time.
