Description
Technical Field
The invention relates to a washing machine in the field of washing, in particular to a washing machine with a steam washing function, and further relates to a control method of the washing machine.
Background
To meet the consumer demand, additional functions of washing machines come up endlessly, such as steam washing, sterilization, deodorization, etc. In the existing washing machine products, the modes for realizing the steam washing function are divided into the following two types:
one is to add a special steam generator on the washing machine, after the water is vaporized into high temperature steam in the generator, the steam is flushed into the outer cylinder, so as to realize the functions of quick washing, sterilization and deodorization of the clothes.
Chinese patent application No. CN200510083626, which describes a steam generating device of a washing machine, including a housing having a receiving space for storing water; and a heater disposed in the housing for heating the water stored in the housing. The washing machine is additionally provided with the independent steam generating device, so that steam is generated by using water and flows into the outer drum of the washing machine, and the aim of performing high-temperature disinfection treatment on clothes in the inner drum by using the steam is fulfilled.
Although the proposal of separately adding the steam generator on the washing machine has more steam generation amount, the washing machine has better washing and sterilizing effects on clothes. However, since the steam generator needs to be separately installed, the production cost of the washing machine increases; meanwhile, the independently installed steam generator also occupies the inner space of the washing machine in an extruding way, so that the whole size of the washing machine is increased, and the capacity of the inner barrel is reduced.
The other is to immerse a heater in the tub of the washing machine in the washing water in the tub, and heat the washing water, thereby generating steam. However, in the washing machine using this method, since the total amount of the washing water in the tub is large, the heating rate is slow, the amount of generated steam is small, and the effect is not desirable.
The present invention has been made in view of this situation.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a washing machine with a steam washing function so as to realize the purposes of generating steam in an outer cylinder to sterilize and quickly moisten clothes at high temperature; another object is to achieve the object of rapidly generating a large amount of steam using a heater in the tub.
In order to solve the technical problems, the invention adopts the technical scheme that:

Further, the heater is arranged at a water outlet at the bottom of the outer barrel, and a gap for water flow to pass through is arranged between the partition plate and the water outlet.
Further, a groove which is sunken downwards is formed in the bottom of the outer barrel, and the water outlet is formed in the bottom of the groove; the heater is arranged in the groove, and the partition plate is arranged between the heater and the bottom of the groove; preferably, a certain distance is arranged between the partition board and the bottom of the groove.
Furthermore, the partition board horizontally covers the cross section of the groove, at least one water leakage hole for water flow to pass through is formed in the partition board, and the water leakage hole and the heater are arranged in a staggered mode;
preferably, the water outlet of the outer barrel is arranged below one side of the partition plate, the heater is arranged above the other side of the partition plate, and the water leakage holes are correspondingly arranged on the partition plate above the water outlet, so that water flow can directly flow into the water outlet through the water leakage holes.
Further preferably, the bottom of the groove is inclined downwards from the outer periphery to the water outlet, and the partition plate is inclined downwards from the outer periphery to the water leakage hole.
Further, at least a part of the outer circumference of the partition is spaced from the groove by a water leakage gap to allow water to flow therethrough.
Another object of the present invention is to provide a control method of any one of the above washing machines, characterized in that: and (3) feeding water into the outer barrel until the water level of the fed water is higher than the heater and lower than the bottom of the inner barrel, heating and vaporizing the fed water at the upper part of the partition plate by the heater to generate vaporized steam in the outer barrel, and heating and wetting the clothes in the inner barrel by the steam.
Further, when water is fed into the outer cylinder, the water flows through the gap between the inner cylinder and the outer cylinder and directly flows and is collected at the heater at the bottom of the outer cylinder.
Further, in the process that the heater heats the inlet water above the partition plate to generate high-temperature steam, the water level in the outer barrel is always higher than the heater.
Further, in the process that the heater heats the inlet water above the partition plate to generate high-temperature steam, the inner barrel rotates at a certain rotation-stop ratio at the same time.
Furthermore, before the washing machine executes the normal washing program, high-temperature steam is generated in the outer cylinder, and after the clothes are heated and moistened for a certain time, the normal washing program is executed.
Furthermore, in the process that the heater heats the water inlet above the partition plate to generate high-temperature steam, the water inlet and outlet pipelines of the outer barrel are all in a disconnected state, so that the high-temperature steam is filled into the sealed inner space of the outer barrel.
After adopting the technical scheme, compared with the prior art, the invention has the following beneficial effects:
through the lower part at the heater sets up the baffle for the heater only needs to heat baffle top, a small amount of intaking, just can generate a large amount of steam fast, and the clothing in the inner tube is heated and moist to the steam that generates in the usable urceolus, makes washing machine have functions such as steam washing, dry clothing, disinfection, deodorization and iron, and the effect is showing. Meanwhile, the partition plate is arranged below the heater, so that the situation of heat waste caused by heating of water at the lower part of the partition plate, particularly in a drain pipe is avoided. Also, the heater has dual effects of heating the washing water in the tub 1 and rapidly generating a large amount of steam, thereby avoiding the need for an additional dedicated steam generating device. Therefore, the cost of the washing machine can be reduced, and the power consumption of the washing machine can be reduced. Meanwhile, the invention has simple structure, simple method and obvious effect and is suitable for popularization and use.
