Disclosure of utility model
The utility model aims to provide a steam generating device which has the advantage of reducing the water supplementing resistance of a water tank.
The technical aim of the utility model is realized by the following technical scheme:

Further provided that the second portion is located inside the first portion.
Or the second part is positioned on the upper side of the first part.
Or the second part is positioned outside the first part.
Further provided that the second part is integrally provided with or detachably connected to the first part.
The water tank is further provided with a connecting plate, the connecting plate is arranged on the connecting plate, and the connecting plate is positioned between the water tank and the steam generator.
It is further provided that the highest point of the installation position of the connection pipe is not more than 50% of the height of the steam generator.
Another object of the present utility model is to provide a household appliance with the steam generating device described above.
The household appliance is one of a clothes airing machine, a garment steamer, a humidifier, a steam cleaner, a steam iron and a steam oven.
In summary, the utility model has the following beneficial effects:
First, in the present utility model, the air flow resistance of the first portion is smaller than that of the second portion, for example, the medium in the first portion of the connection pipe is air, i.e., an empty pipe. The medium in the second portion is a wick that circulates the working fluid through the porous structure. When the steam generator is in operation, steam flows in the form of bubbles from the hollow tube of the first portion to the water tank. At the same time, water in the tank flows back to the steam generator from the wick in the second portion. The hollow tube section is responsible for transporting the vapor, while the wick section is responsible for circulating the liquid working fluid. The double-channel design effectively prevents the reverse interference of bubbles on water flow, the flow paths of the two channels do not interfere with each other, and the obstruction of countercurrent steam on water supplementing of the water tank is reduced. Bubbles enter the water tank from the steam generator, water flows from the water tank to the steam generator, and the interference of the bubbles to water flow is effectively avoided through the flow paths of the physical isolation gas and the liquid. So that the whole process is continuous, and the water flow reverse or interruption possibly caused by bubbles is prevented. Continuous generation of steam benefits from the independent and stable flow of the two fluids. The steam generator is capable of generating steam without interruption, thereby improving the efficiency of the overall system.
Second, in the present utility model, a porous structure is used to circulate the wick of the working fluid, and water in the water tank flows back to the steam generator through the porous structure of the wick. The porous structure supports spontaneous upward movement of water flow, overcomes gravity, continuously supplies water through capillary action, and further improves the efficiency of the whole system by improving adsorption efficiency.
Thirdly, in the utility model, the highest point of the connecting pipe is set below 50% of the height of the steam generator, which is helpful for effectively controlling the situation that boiling water is sprayed along with steam. When the steam generator is operated, the generated steam may be partially hydrated. If the highest point of the connection pipe is set too high, boiling water may be sprayed together with steam, causing unnecessary energy loss and safety hazards. Therefore, limiting it below this height can effectively avoid this.
Fourth, the water supplied into the water tank in the prior art is usually warm water, the working temperature of the steam generator needs to be close to the boiling temperature, the supplied normal-temperature water easily causes the sudden drop of the working temperature of the steam generator and affects the continuous injection of steam, the water tank and the steam generator can be communicated by using the connecting pipe provided by the application, the two parts of the water supply and the steam reflux are respectively positioned at the first part and the first part in the connecting pipe, the two paths are not interfered with each other, the heat of the steam generator is brought into the water tank by the steam reflux on the first part, and after the temperature of the water tank is raised, the heat flow at the bottom is supplied to the steam generator from the second part, so that the boiling temperature is quickly reached, and the steam is continuously output.

The specific structure of the liquid absorbing core is not limited, the porous structure of the liquid absorbing core is one of porous medium, silk screen, groove and sintered metal powder, and as an alternative embodiment, the porous structure of the liquid absorbing core is at least one or more composite structures.
A water pump is generally required to be provided between the water tank 200 and the steam generator 100 as a power source to be driven for water replenishment, and a valve 400 is provided on a connection pipe 300 of the water pump. When the steam generator 100 is operated to generate a large amount of steam and the water amount is insufficient, the valve 400 needs to be opened to start the water pump to replenish water. During the water replenishment, the resistance to the counter flow of steam may be addressed by the first portion 301 and the second portion 302 of the different compartments. For example, the first portion 301 and the second portion 302 of the connecting pipe 300 form two independent channels, so that the water replenishing flow portion and the steam backflow portion in the connecting pipe 300 are separated in different channels in the water replenishing process, and the resistance of the steam backflow is reduced, so that the water replenishing flow persistence is better.
Further, the water replenishing of the water tank 200 may be performed in a water pump-free manner, as shown in fig. 2 and 10, in the water replenishing process of the water tank 200 and the steam generator 100, when the water tank 200 is installed to replenish water to the steam generator 100, water in the water tank 200 enters the steam generator 100 through the connecting pipe 300, the highest point of the water in the water storage cavity of the steam generator 100 reaching the connecting pipe 300 is the highest water level, water pressures at two sides of the water tank 200 and the water storage cavity reach an equilibrium state near the water level, the highest water level of the water storage cavity is stabilized near the height, and at the moment, the liquid level in the water tank 200 is not lower than the liquid level of the water in the evaporator.
When the steam generator 100 is powered on and heated, the internal water is heated and boiled to become steam, when the steam generator starts to work just, the high pressure in the steam generator 100 can press the water in the water tank 200 to be unable to enter, as the water in the steam generator 100 is evaporated continuously along with the working time, the liquid water is gradually converted into steam, the water storage capacity in the steam generator 100 is reduced, the air pressure in the steam generator 100 is reduced, and then the water in the water tank 200 flows to the steam generator 100 for water supplement. In this process, the water storage amount inside the steam generator 100 is lowered, the liquid level of the steam generator 100 is lowered below the first portion 301 of the connection pipe 300, a certain amount of bubbles are generated on the surface layer of the steam generator 100 during the boiling process, the bubbles flow from the first portion 301 to the side of the water tank 200, and the water in the water tank 200 enters the steam generator 100 from the second portion 302 of the connection pipe 300 to be replenished. This dual channel design effectively prevents the reverse interference of the air bubbles with the water flow, the flow paths of the two do not interfere with each other, and the process is continuous and the interruption of the water flow is not caused by the formation of the air bubbles. Thus, the steam generation can be maintained continuously, thereby solving the problem of steam generation discontinuity.
In one embodiment, the steam generating device of the above embodiment is applied to a clothes drying machine, and provides steam for a steam care function of the clothes drying machine, and in order to reduce the thickness of the module, the height of the steam generator 100 is limited, and in order to ensure sufficient supply of steam, it is necessary to have enough water in the steam generator 100. The height of the connection pipe 300 determines the highest water level in the steam generator 100, so that the ratio of the height of the connection pipe 300 located on the steam generator 100 to the entire height of the steam generator 100 is greater than 0% and less than or equal to 60% in the present embodiment. In another alternative embodiment, the ratio of the height of the connection pipe 300 at the evaporator to the entire height of the evaporator exceeds 60%, and water drops sprayed from boiling water in the water storage chamber are easily overflowed when boiling, so that the water drops are sprayed onto the laundry together with the steam. In addition to the above-described embodiments, as a preferred embodiment, the ratio of the height of the connection pipe 300 located on the steam generator 100 to the entire height of the steam generator 100 is 50%. At this time, a sufficient water supply amount can be ensured, and water drops can be prevented from splashing and overflowing to the outside of the steam generator 100.
In general, the water storage height of a conventional evaporator may be approximately equal to the evaporator height, and in the case of a specific evaporator having a thicker wall thickness, the water storage height is taken as a reference, and the position of the connection pipe 300 should be understood as a ratio of the water storage heights.
