Problems solved by technology

[0007] Although the purpose is to sterilize and kill mites using steam and hot water, the penetration effect of steam can hardly be expected in the inner and lower parts of folded blankets and futons
[0008] In addition, ordinary blankets are made of chemical fibers such as acrylic and polyester, which are not heat-resistant, and sometimes the fibers themselves are deformed by steam or hot water, and the texture becomes hard.

Embodiment 1

[0024] Below, according to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 order will be described.

[0025] figure 1 It is a longitudinal sectional view showing the structure of the washing and drying machine according to the embodiment of the present invention, figure 2 It is a functional block diagram of the washing and drying machine in embodiment of this invention.

[0026] In the outer frame 1 of the washing and drying machine, an outer tank 2 for storing washing water is arranged, and the outer tank 2 is supported in a vibration-proof manner by four suspension members (not shown) hanging from the upper corners of the outer frame 1 , and arranged in the central part of the outer frame 1 along the longitudinal direction. The washing tank 3 disposed in the outer tank 2 is formed in a bottomed cylindrical shape long in the axial direction using a stainless steel plate. Through-holes 7 for passing water and ventilation are formed in...

Embodiment 2

[0090] During heating as in Example 1, when the temperature of the warm air is detected by the warm air temperature sensor 21 and exceeds 80°C, the intermittent spraying of water mist is started. , instead the intermittent spraying of water mist is started after heating for a predetermined time.

[0091] Specifically, as Figure 7As shown in the flow chart of FIG. 2 , the driving device 8 is controlled to rotate the washing tank 3 at a low speed (step S501 ). And the control part 9 controls the fan drive circuit 36, operates the blower 19, and supplies air into the washing tub 3 (step S502).

[0092] After that, the control unit 9 controls the heater switch 35 to be turned on, and makes the heater 17 perform a strong operation (step S503 ). While starting the strong operation of the heater 17, start the strong operation timer (step S516), judge the amount of blankets and quilts as laundry (step S516), and set the heating time corresponding to the amount of laundry.

Embodiment 3

[0101] The difference of the heating and humidification process in other embodiments is that, in the case of not having the spray nozzle 27 and the mist net 28 as in the embodiment 1 or 2, the main water supply solenoid valve of the water supply unit 11 is opened to supply tap water to carry out Cooling and humidification of laundry.

[0102] The main water supply solenoid valve of the water supply unit 11 can supply 10 to 15 L of tap water per minute, but because it is necessary to keep the blanket and bedding as washings to cool and the temperature at which the mites die, it is turned on for 2 seconds and then turned off 208 Seconds of intermittent water supply. The ON / OFF time allocation is a control scheme, which measures the time it takes for water to reach a predetermined water level during the washing process or rinsing process, determines the water pressure, and selects and sets from a plurality of time allocations, thereby It is possible to prevent the temperature of...

Abstract

PROBLEM TO BE SOLVED: To provide a washer-dryer machine capable of effectively annihilating mites, while preventing the temperature of laundry such as a blanket having a low resistance against heat from excessively rising in heating, such that the laundry is protected from the heat.SOLUTION: When a heating treatment for supplying warm air into a washing tub is performed, water is supplied into the washing tub by water supply means to perform a cooling treatment for cooling the laundry.SELECTED DRAWING: Figure 1

Description

technical field [0001] The present invention relates to a washing and drying machine capable of washing blankets, quilts, and the like. Background technique [0002] In order to clean blankets and futons, which are often in direct contact with human skin, they are generally washed, dried in the sun, or sucked up with a vacuum cleaner. The feces and corpses of mites can be removed by washing and cleaning, but it is not easy to kill mites when washing and drying in the sun, and it is not easy to absorb mites clinging to the fibers of thick blankets and bedding. [0003] The results of an experiment that 100% of mites of the dust mite family, which are the most numerous in the house, die when they are heat-labile and kept at a temperature of 50° C. or higher for 20 minutes are disclosed. [0004] Patent Document 1 describes a washing machine having such a function of killing mites by heat. This patent document 1 describes "a washing machine with a sterilizing and mite-killing...
