Those skilled in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

As shown in Fig. 1 and Fig. 2, Fig. 1 is a schematic structural diagram of a pulsator washing machine according to an embodiment of the present invention, and Fig. 2 is an enlarged view of part A in Fig. 1 . Referring to FIG. 1 , the pulsator washing machine mainly includes a cabinet and an outer tub 1 , an inner tub 2 and a sterilizing device 3 arranged in the cabinet. Wherein, the sterilizing device 3 is located between the bottom of the outer barrel 1 and the inner barrel 2 along the axial direction of the inner barrel, and between the outer barrel 1 and the barrel wall of the inner barrel 2 along the radial direction of the inner barrel. Through such a setting, the maximum irradiation distance and range of the sterilizing device are fully utilized, and the washing water between the irradiated outer tub and the inner tub can be sterilized efficiently, which improves the sterilization efficiency of the clothes processing equipment. Between the outer barrel and the inner barrel, the volume is small, the efficiency is high, the energy consumption is small, and the clothes will not rub and collide with the sterilizing device, thus prolonging the service life of the sterilizing device.

Referring to Fig. 2, in a possible implementation manner, the fixing method of the sterilizing device in the washing machine is as follows: the bottom of the outer tub 1 of the pulsator washing machine is provided with an installation position 11, and the sterilizing device 3 includes a lamp housing 31 and a lamp housing. The lamp body 32 and the lamp housing 31 are fixed to the installation position 11 by fasteners (such as screws). Preferably, the sterilizing device 3 can be pre-bonded to the installation position 11 with an adhesive (such as waterproof glue) so that the sterilizing device 3 is fixed at a proper position of the installation position 11, and then the sterilizing device 3 is further fastened by screws.

Still referring to FIG. 2 , the side wall of the inner tub 2 is a diameter-reducing portion 21 near the bottom of the bucket. The diameter-reducing portion 21 includes at least one diameter-reducing section, and the diameter of the diameter-reducing portion 21 decreases from top to bottom, preferably gradually decrease. Through the setting of the reduced diameter portion 21, the washing water in the irradiation range of the sterilizing device can be increased, the sterilizing efficiency is improved, and the sterilizing effect is guaranteed. It can be understood that, when the reduced-diameter portion includes multiple reduced-diameter sections, the diameter of the lower reduced-diameter section should be smaller than that of the upper one so as to prevent the lower reduced-diameter section from blocking the light from the upper reduced-diameter section. As shown in FIG. 2 , in a specific embodiment, the reduced diameter portion 21 includes a first reduced diameter section 211 and a second reduced diameter section 212 arranged from top to bottom, the (first and second) reduced diameter sections Both are structures whose diameters gradually decrease from top to bottom, such as hollow circular truncated cones. In the cross-section shown in Figure 1, the outer edge lines of the (first and second) diameter reducing sections are oblique lines inclined from top to bottom to the left, and the outer edge lines of the first diameter reducing section are in line with the vertical direction The angle between them is smaller than the angle between the outer edge line of the second reduced diameter section and the vertical direction. Preferably, a ring-shaped protrusion can be provided near the upper position of the first reduced-diameter section, so that when the light of the sterilizing device hits the ring-shaped protrusion, it can be reflected to the lower area, thereby ensuring the sterilization effect.

It can also be understood that, in addition to the oblique straight line mentioned above, the outer edge line of the reduced diameter section can also be a curve or a combination of a straight line and a curved line. In the case of affecting the washing of the clothes by the inner tub, it is sufficient to allow the sterilizing device to irradiate a wider range of washing water.

Continue to refer to Fig. 1, the pulsator washing machine also includes an internal circulation assembly, the internal circulation assembly mainly includes a circulation pipeline 4 and a circulation pump 41 arranged on the circulation pipeline, the upper end of the circulation pipeline 4 communicates with the upper part of the inner tub 2, and the circulation pipeline The lower end of 4 is fixedly connected with the bottom of tub 1 and communicates with. Through such arrangement, the washing water can form a waterfall-like water flow when circulating between the inner tub and the outer tub, and can better wash clothes. Combined with the sterilizing device of the present application, after the washing water in the inner tub flows between the inner tub and the outer tub, it is fully sterilized by the sterilizing device, and then the sterilized washing water falls into the inner tub again from the upper part of the inner tub through the above-mentioned circulation assembly, and thus circulates. That is, the washing water in the sterilizing area and the non-sterilizing area can be fully exchanged, and finally all the washing water is sterilized, the sterilizing efficiency of the wave wheel washing machine is improved, and the energy consumption of sterilizing is reduced.

Preferably, the sterilizing device 3 is a UV ultraviolet germicidal lamp and there can be one or more UV ultraviolet germicidal lamps, such as a plurality of UV ultraviolet germicidal lamps are evenly arranged along the circumferential direction of the outer barrel 1, and correspondingly, the circumferential direction of the outer barrel 1 A plurality of installation positions corresponding to UV rays are evenly arranged, so that the washing water is rapidly sterilized during the rotation of the pulsator, and the sterilizing efficiency of the pulsator washing machine is improved. Obviously, a plurality of UV ultraviolet germicidal lamps can also be unevenly arranged along the circumferential direction of the outer barrel 1. For example, the UV ultraviolet germicidal lamps are divided into two groups arranged symmetrically, and each group includes a plurality of UV ultraviolet germicidal lamps. The UV germicidal lamps can be evenly distributed. Those skilled in the art can make reasonable adjustments to the settings of the UV germicidal lamp according to the actual situation and needs. In addition, it can be understood that the sterilizing device is not limited to the UV sterilizing lamp described in the above embodiments, but can also be other forms of sterilizing lamps or sterilizing components, which can be flexibly selected by those skilled in the art according to actual conditions and needs.

It can be seen that the pulsator washing machine of the present invention includes an outer tub, an inner tub and a sterilizing device, the sterilizing device is located between the bottom of the outer tub and the inner tub along the axial direction of the inner tub, and is located on the outer tub and the inner tub wall along the radial direction of the inner tub. between. Through such setting, the sterilization efficiency of the wave wheel washing machine is improved, and the service life of the sterilization device is prolonged. Further, the bottom of the outer tub is provided with an installation position for installing a sterilizing device, and the side wall of the inner tub is provided with a diameter-reducing part near the bottom of the tub. The irradiation distance and range, and the washing water is sterilized in a cycle, which further improves the sterilization efficiency of the pulsator washing machine and reduces the sterilization energy consumption of the pulsator washing machine.

In addition, the pulsator washing machine also includes a controller. The controller is used to control the action timing of the sterilizing device. By controlling the sterilizing device to start in a suitable washing program, the sterilizing efficiency of the pulsator washing machine is improved and the sterilization energy consumption of the pulsator washing machine is reduced. It can be understood that the controller can also have other functions such as washing mode selection, washing water heating, alarm, etc., and the following will only be described in conjunction with the function of controlling the action timing of the sterilizing device, so as to highlight the gist of the present invention.

Based on the above-mentioned pulsator washing machine, the washing control method of the pulsator washing machine specifically includes the following steps:

The controller judges whether to start the sterilizing program according to the state of the washing program and controls the water intake to the first set water level as the sterilizing water level, so as to sterilize the clothes and the washing water.

Assume that the water inlet level is the full water level and the sterilization water level is lower than the full water level in the case of normal washing. This is because the function of the first set water level mainly includes: making the sterilizing process run as far as possible in the state where the washing water submerges the clothes to ensure the sterilizing effect; and making the sterilizing process run with less water to save electric energy. Specifically, due to the limited irradiating distance of the sterilizing device, when the water level of the washing water is high, the sterilizing device can only irradiate a limited range, and increasing the washing water will only increase the sterilizing time of the sterilizing device and reduce the sterilizing efficiency. Taking the sterilizing device as a UV germicidal lamp as an example, the best sterilizing distance of the UV germicidal lamp in water is 100mm outward from the UV germicidal lamp. After exceeding 100mm, the sterilizing effect of ultraviolet rays will be weakened. By controlling the water intake to the lower first set water level, the sterilizing device can quickly and fully sterilize the washing water and clothes, thereby improving the sterilizing efficiency and reducing the energy consumption of sterilizing.

In view of this, the first set water level should be set to a lower water level that can take both factors of sterilization effect and electric energy saving into consideration. It should be noted that the first set water level may be the water level determined by the control of the fuzzy control program, or a low water level preset in the washing program. Among them, the principle of the fuzzy control program is: to obtain the amount of information through the sensor, and send the collected information to the microcomputer. After the comprehensive judgment of the microcomputer, select the appropriate water level, washing time, Washing action and other working parameters to execute the best washing program. For example, a water level sensor can be set to automatically sense, set and automatically control the water level according to the amount of laundry.

In addition, it should be noted that starting the sterilization program and controlling the water intake to the first set water level can be understood as starting the sterilization device at the same time as the water intake starts or during the water intake process, or it can be understood as first controlling the water intake to the first set water level. Once the water level is set, turn on the sterilizer again. Those skilled in the art can make reasonable adjustments to the timing of water intake and opening of the sterilizing device according to actual conditions and needs.

As shown in FIG. 3 , FIG. 3 is a first schematic flowchart of a washing control method of a top-wheel washing machine according to an embodiment of the present invention. Referring to Figure 3, the steps of judging whether to start the sterilization program and controlling the water intake to the first set water level according to the state of the washing program specifically include:

S10, judging whether the washing procedure enters the rinsing stage;

S20. When the washing procedure enters the rinsing stage, start the sterilization procedure and control the water intake to the first set water level. For example, the laundry and wash water can be sterilized before, during or after the rinsing phase.

Since the washing water is relatively turbid in the washing stage before rinsing, the penetrating power of the UV germicidal lamp in the washing water will be weakened at this time, and the effective sterilization range will be reduced. In the rinsing stage, most of the stains on the clothes have been cleaned and discharged from the wave-wheel washing machine. At this time, the turbidity of the washing water is already low. The penetrating power will be enhanced, the irradiation range will be increased, and the area of the washing water irradiated will be correspondingly increased, so that the sterilization efficiency can be improved.

It should be understood that the cycle of washing water between the inner and outer tubs is also required during the start of the sterilization process, so the sterilization stage should be the sterilization accompanied by the circulation of the wash water, such as the sterilization accompanied by rinsing. When the pulsator washing machine is provided with an internal circulation assembly, the sterilization will be more sufficient. Preferably, the rinsing stage of the washing program includes a first rinsing stage and a second rinsing stage, and before entering the second rinsing stage, the sterilization program is started and the water intake is controlled to the first set water level.

Since the clothes and washing water have reached a basically clean level after the completion of the first rinsing stage, the UV germicidal lamp is first turned on for sterilization before continuing to rinse the clothes and washing water in the second rinsing stage. At this time, the turbidity of the washing water has been significantly reduced, and the penetrating power of the UV ultraviolet germicidal lamp has been significantly enhanced. Therefore, setting the sterilization stage at this time can significantly increase the irradiation area of the UV ultraviolet germicidal lamp, and can significantly improve the UV ultraviolet germicidal lamp. Bactericidal efficiency. The whole process of the washing control method will be described below with reference to FIG. 4 .

As shown in FIG. 4 , FIG. 4 is a second schematic flowchart of a washing control method of a top-wheel washing machine according to an embodiment of the present invention. Referring to FIG. 4 , the complete laundry washing process includes: 1) After the user starts the washing program, it first enters the washing stage, which is mainly used to clean the stains on the clothes. 2) Enter the first rinsing stage after the washing stage ends, and the clothes are basically clean at the end of this stage. 3) Then enter the water to the lower second set water level to sterilize the clothes, and the washing water with low water level and low turbidity can guarantee the bactericidal effect. 4) After the sterilization, turn off the UV germicidal lamp and continue to control the water intake to the second set water level (such as the full water level higher than the first set water level corresponding to normal rinsing) and rinse the clothes for the second time. 5) After the end of the second rinsing stage, enter the subsequent dehydration stage until the end of the washing procedure.

It should be noted that the sterilization stage may be a newly added stage in the (first, second) rinsing stage of the original washing program, or may be a specific stage generated by re-planning the original second rinsing stage. For example, assuming that the duration of the second rinse stage in the original washing program is 15 minutes, the duration of the second rinse stage can still be maintained at 15 minutes and a 5-minute sterilization stage can be added before that, or the original Some second rinsing stages are divided into two sub-stages: the first sub-stage is the sterilization stage, that is, the stage in which the sterilization program is started and the water intake is controlled to the first set water level and sterilized while rinsing, such as the duration of the sterilization stage 5 minutes; the second sub-stage is the improved second rinsing stage, that is, the stage of first controlling the water intake to the second set water level and continuing to rinse the clothes, for example, the duration of this stage is 10 minutes. Or as an improvement, the duration of the original second rinsing stage is appropriately extended, and the extended second rinsing stage is divided into two sub-stages: rinsing while sterilizing and rinsing alone. For example, if the original second rinsing stage is extended to 17 minutes, the duration of the first substage is 5 minutes, and the duration of the second substage is 12 minutes. Through this setting, on the basis of ensuring sufficient rinsing, saving Water resources are saved, sterilization efficiency is improved, and energy consumption for sterilization is reduced.

It should be noted that, in addition to being between the (first and second) rinsing stages as in the above example, the sterilization stage can also be after the second rinsing stage. For example, the rinsing stage can also include more rinsing stages, such as including three rinsing stages, and the sterilization stage is between the (second and third) rinsing stages. Still taking the example that the rinsing stage only includes two rinsing stages, the sterilization stage can also be performed after the second rinsing stage. Such as can be between the second rinse stage and the spin stage.

In addition, since the wave wheel washing machine has washed the clothes, there may be washing water residue between the outer barrel and the inner barrel, and the humid environment plus the washing water dissolved in bacteria is a good environment for breeding and multiplying bacteria. It is likely that a large number of bacteria and germs will grow between them, causing secondary pollution to the clothes to be washed next time. In view of this, after the dehydration stage, that is, after the clothes are washed, the controller starts the sterilization program for the third set time (such as the length of the third set time is less than the second set time), that is, the controller and the sterilizing device Improve and make full use of the sterilizing device, effectively avoiding the phenomenon of secondary pollution to the clothes to be washed next time.

It can be seen that the above washing control method includes the steps of: judging whether to start the sterilization program according to the status of the washing program and controlling the water intake to the first set water level. By quickly and fully sterilizing the washing water and clothes at the first set water level, the sterilizing efficiency is improved and the energy consumption of sterilizing is reduced. Preferably, when the washing procedure enters the rinsing stage, the sterilization procedure is started and the water intake is controlled to the first set water level. By turning on the sterilization program during the rinsing stage, the UV germicidal lamp has stronger penetrating power, a larger irradiation range, and a larger area of the washing water that is irradiated, which improves the sterilization efficiency. More preferably, the rinsing stage includes a first rinsing stage and a second rinsing stage, and before or after the washing program enters the second rinsing stage, the sterilizing program is started and the water intake is controlled to the first set water level. Since the UV ultraviolet germicidal lamp can fully sterilize the washing water and clothes in the washing water with a lower water level, through such treatment, on the premise of ensuring sufficient rinsing, water resources are saved, the sterilization efficiency is improved, and the sterilization energy is reduced. consumption.
