The following description is provided for the purpose of better understanding the technical solutions of the present invention.
Firstly, the technical scheme of the invention has simple integral design, only the steam washing module is added under the structural frame of the existing washing machine, and the volume of the washing machine is not increased. The washing machine with the steam washing function has the advantages of high steam generation speed, short time, good continuity and large quantity, and can improve the steam washing effect; in addition, the speed of the fan and the speed of the atomized water generated by the atomizer can be adjusted, so that the temperature of the steam can be conveniently adjusted and controlled to adapt to steam washing of clothes made of different materials.
The working principle of the washing machine with the steam washing function is roughly as follows: the atomized water storage device is provided with a water inlet, the water inlet is connected with a solenoid valve for controlling water source through a water inlet pipe, and the water source is automatically controlled to enter the atomized water storage device; the atomization generator can automatically run and generate atomized water when contacting with water, then the atomized water is driven by negative pressure generated by the action of the fan to enter the air channel from the atomization water outlet, and the atomized water moves to the heating element along with airflow generated by the fan; the particle size of the atomized water is small, the total contact area with the heating element is large, the contact is very sufficient, and the process of converting the atomized water into steam can be realized in a short time; the formed steam enters the part of the washing outer barrel close to the barrel opening from the first hose and then returns to the air channel from the second hose connected with the part of the washing outer barrel close to the barrel bottom, thereby realizing the circulation of the steam wind in the whole washing outer barrel and realizing the purpose of steam washing.
Preferably, the atomization generator of the present invention is an ultrasonic atomizer. The ultrasonic atomizer breaks up a liquid water structure by utilizing electronic high-frequency oscillation to generate naturally elegant water mist, wherein the water mist is 1-5 microns of ultrafine particles, the uniformity is good, and extra heating or any chemical reagent is not needed. Compared with the direct heating atomization mode, the energy can be saved by 90 percent. In addition, the ultrasonic atomizer releases a large amount of negative ions in the atomization process, the negative ions and smoke, dust and the like floating in the air generate electrostatic reaction to precipitate the negative ions, and meanwhile, harmful substances such as formaldehyde, carbon monoxide, bacteria and the like can be effectively removed, and multiple laundry care experiences can be obtained at the same time.
Furthermore, in order to enable the atomized water generated in the atomized water storage device to enter the air duct more quickly and avoid the phenomenon that a large amount of atomized water is retained in the atomized water storage device to cause the internal air pressure to increase rapidly, the atomized water storage device can be connected with the part, close to the fan, on the air duct by the atomization pipe, of the atomized outlet of the atomized water storage device. Under the drive of the negative pressure generated by the fan, atomized water generated in the atomized water storage device is quickly guided into the air channel and continuously generates atomized water which is converted into steam under the action of the snake-shaped heating pipe, so that continuous and sufficient steam is ensured to be used for washing in the washing machine. The problems of small steam quantity and discontinuous steam existing in the washing machine with the steam washing function in the prior art are solved.
Furthermore, in order to simplify the structure as much as possible, save materials and reduce the cost, the technical scheme of the invention combines the atomizer with the function of sensing low water level (namely, the atomizer is automatically cut off and does not work continuously under the condition that the atomizer is not contacted with the water surface), skillfully arranges an overflow opening communicated with the washing outer barrel or the drain valve at the upper part of the atomization water storage device, and when the water level in the atomization water storage device is higher, the atomization water storage device can enter the washing outer barrel or the drain valve through the overflow opening to prevent the condition of overhigh water level in the atomization water storage device, thereby avoiding the influence of water overflow to other parts in the washing machine on safe use. The technical scheme solves the problem of low water level and high water level judgment in the simplest mode, simplifies components and improves the space utilization efficiency of the washing machine.
Further, in order to more accurately control the minimum water level, two or more probes may be fastened to the bottom of the housing of the atomizer, the probes being arranged at a distance and extending vertically out of the housing by a certain height, and the atomizer may be activated only if all the probes are submerged in water. The atomizer has the automatic protection function of cutting off water supply, and when the liquid level is lower and the probe is above the water surface, the atomizer stops working.
Of course, on the basis of the spirit of the technical scheme of the invention, the design of the liquid level judgment device of the atomized water storage device can also be realized by a method of a liquid level meter commonly used in the prior art, namely, the liquid level meter is arranged in the atomized water storage device and is preset with a corresponding lowest liquid level and a corresponding highest liquid level, so that the liquid level can be controlled within a certain range more accurately. Although this solution is higher in cost than the above-described design of the overflow, the technical problem of water level determination can be solved.
In the technical scheme of the invention, the bottom of the atomized water storage device can be preferably of an inclined chamfer structure, so that the internal space of the atomized water storage device is as large as possible, and a safe distance is kept between the atomized water storage device and the outer washing barrel, the idle space between the outer washing barrel and the shell in the washing machine in the prior art is better utilized, the space utilization rate is improved, and the size of the washing machine is prevented from being further increased.
Furthermore, the atomizing water storage device is arranged in an idle space between the washing outer barrel and the shell in the structure of the existing washing machine, so that the space of the washing machine is fully utilized, the size of the washing machine is prevented from being further increased, and inconvenience is brought to users in use.
Furthermore, the heating element is arranged in the air duct and at the downwind position of the airflow generated by the fan.
