The specific embodiment
Below, be described with reference to the accompanying drawings the embodiment of roller washing machine provided by the invention with steam raising plant.
Fig. 3 to Fig. 4 is the internal structure schematic diagram of the steam raising plant in the embodiment of the invention.Fig. 3 represents the pressure differential of utilizing the heater housing inside and outside, discharges the structure of the inner steam that generates of heater housing, and Fig. 4 represents because the inside and outside pressure differential of heater housing, and water flows into the state of heater housing inside.
As shown in Figure 3, the roller washing machine steam raising plant 50 in the embodiment of the invention comprises: inside is formed with the housing 51 in the space that can hold low amounts of water; Be arranged at the heater case 300 of housing 51 inside, the inside of heater case 300 is formed with certain space, be provided with the water that heating is stored in housing 51 inside in its space, make it produce the heater 55 of steam, also flowing in the space is fed to housing 51 internal water, and by the heating of heater 55 water that flows into is become the steam discharge.
Be formed with water-supply valve 15 (with reference to Fig. 1) in a side of housing 51 and be connected, move the water to flow into the admission port 103 (with reference to Fig. 1) of housing 51 inside, be formed with (with reference to Fig. 1) inside that offers cylinder 20 for the steam that will generate on the opposite side, the delivery outlet 105 that is connected with steam supply pipe 53 (with reference to Fig. 1).
Though heater 55 can use the winding heater 55 at the water of the outer survey heating internal reservoir of housing 51, the thermal efficiency that is fully immersed in the shell type heater 55 that directly adds hot water under the state in the water is higher, is more suitable for adding in the short time hot water.
Be provided with the level sensor (figure does not have expression) that is used for detecting water level inside and be used to detect temperature detection sensor in a side of housing 51 by the temperature of the steam of heater 55 generations.
Temperature sensor detects the temperature of the housing 51 inner steam that generate, and when the temperature value that is detected has surpassed setting, cuts off the power supply of heater 55, prevents the overheated of heater 55.
Level detection sensor is used to detect the water level of housing 51 inside, makes the amount of the water that provides keep certain level.
That is, when the water level of the water of housing 51 internal reservoir is lower than a reference value, open water-supply valve 15 supplementing water, and when the water level of the water of internal reservoir is higher than a reference value, cut off water-supply valve 15, and interrupt feedwater, start heater 55 generation steam simultaneously.
Heater case 300 is arranged on housing 51 inside, and possesses certain space, and inside is provided with heater 55, is used to heat a part of water that offers housing 51, makes it become steam and discharges.
Specifically, housing 51 inside of steam raising plant possess having heaters shell 300, are used for a spot of water generation of heating rapidly steam, and preferably heater case 300 is to comprise the state setting of heater 55.
Heater case 300 can be made of upper and lower part housing 301,303.
The bottom of the lower case 303 in the heater case 300 should be provided with the inflow portion that the water that will be fed to housing 51 inside offers heater case 300 inside.Inflow portion can be made of at least one or more than one inflow entrance 310.
In the heater case 300, the discharge portion of discharge by the steam of heater 55 heating generations should be set on a side of upper body 301.
Preferably discharge portion is arranged on the top of upper body 51, can be made of at least one or more than one outlet 330.
And preferably the diameter D1 of each inflow entrance 310 is less than the diameter D2 of each outlet 330.
This is for the flow velocity that makes the water that flows into by each inflow entrance 310 flow velocity less than the steam of discharging by each outlet 330.
Steam raising plant with as above structure is supplied to heater case 300 inside by giving housing 51 feedwater with water, and utilizes heater 55 heating to be fed to the water of heater case 300 inside, it is become steam after, the steam of generation is offered in the cylinder.
As shown in Figure 3, when heater case 300 pressure inside during greater than the pressure of heater case 300 outsides, the heater case 300 inner steam that form will be discharged to the outside of heater case 300.
As shown in Figure 4, when heater case 300 pressure inside are lower than the pressure of heater case 300 outsides, water will enter the inside of heater case 300.
Below, in conjunction with the accompanying drawings to as above specific description is more carried out in the course of action and the effect of the steam raising plant of formation.
Fig. 5 is the flow chart of the steam control method in the embodiments of the invention.
As shown in Figure 5, after the washing of washing machine formed beginning, water flowed into housing 51 inside by admission port 103.
The water that flows into housing 51 inside flows into the inside S100 of heater case 300 again from each inflow entrance 310 of lower case 51 formation.
The water that flows into heater case 300 inside is become steam S200 by heater 55 heating.
Heater case 300 pressure inside are owing to the heating work of heater 55 raises, because internal pressure is greater than the pressure of heater case 300 outsides, promptly greater than housing 51 pressure inside, so the heater case 300 inner steam that generate flow into housings 51 inner S300, S400 by each outlet 330.
In this process, because heater case 300 pressure inside are greater than housing 51 pressure inside, so water can not flow into the inside of heater case 300 by each inflow entrance 310 that forms on the heater case 300.
Then, be discharged to the steam of housing 51 inside, the guiding of delivery outlet 105 by housing 51 and the steam supply pipe that is connected with cylinder with delivery outlet 105, the cylinder inside of inflow storage washings.
The steam that forms in the heater case 300 is after discharging certain amount, the decline of water table of heater case 300 inside, heater case 300 pressure inside also can descend simultaneously, and pressure inside will be less than heater case 300 external pressures, promptly less than housing 51 pressure inside S500 thus.
After a certain amount of water being provided for heater case 300 inside, when utilizing heater 55 to heat, heater case 300 temperature inside and pressure rise once more, and inner water becomes steam once more and discharges S600.And above-mentioned repeatedly process.
Then, the steaming of finishing washings scald and action of soaking after, stop the work of steam raising plant, carry out a series of washing stroke, finish the washing of washings.
