Description

Washing apparatus and control method for washing apparatus

Technical Field

The invention relates to the technical field of washing equipment, in particular to washing equipment and a control method for the washing equipment.

Background

Microbubbles (micro-bubbles) generally refer to microbubbles having a diameter of fifty micrometers (μm) or less when the bubbles are generated. Microbubbles may also be referred to as micro-/nano-bubbles, micro-bubbles or nano-bubbles, depending on their diameter range. Microbubbles stay in the liquid for a relatively long time because of their low buoyancy in the liquid. At the same time, the micro-bubbles will shrink under the action of water pressure in the liquid until they break up finally, generating smaller nano-bubbles. In this process, the rising speed of the bubbles becomes slow because they become small, resulting in high melting efficiency. The microbubbles locally generate high pressure and high temperature heat when they are broken, and thus can destroy foreign matters such as organic matters floating in the liquid or adhering to the object. In addition, the contraction process of microbubbles is accompanied by an increase in negative charge, which is typically at a peak state when the microbubbles are 1-30 microns in diameter. These negative charges have a high redox effect and are capable of effectively decomposing contaminants in water. These characteristics provide the microbubbles with a strong cleaning and decontamination capability. At present, microbubbles have been widely used in washing apparatuses such as washing machines.

In order to improve the washing effect, various types of microbubble generating devices are combined in the conventional washing equipment to generate microbubbles in the washing water. However, the water inlet pipeline of the existing washing device is difficult to ensure sufficient gas supply, and thus generation of microbubbles with sufficient content in the fluid is not ensured.

There is a need in the art for a new solution to the above-mentioned problems.

In order to solve the technical problem that the water inlet pipeline cannot ensure sufficient gas supply in the prior art, the invention provides a control method for washing equipment 1. The control method comprises the following steps:

starting the water controller to enable the first pipeline to be filled with water (step S1);

activating the dispenser to pump fluid in the second line to the converging line (step S2);

Fig. 4 is a flow chart schematically showing a control method for a washing apparatus according to the present invention. As shown in fig. 4, in one or more embodiments, after the control method of the washing apparatus 1 of the present invention is started, step S1 is first performed, that is, the water controller 111 is activated to allow the first pipe 11 to be filled with water. The duration of the activation of the water controller 111 depends on the washing requirements, e.g. a suitable period of 2 minutes, or 5 minutes, etc. Simultaneously or subsequently, step S2 is performed, namely to activate dispenser 121 to pump the fluid in second line 12 towards converging line 13. Next, step S3 is performed, namely, water from the first pipe 11 and fluid from the second pipe 12 flow into the merging pipe 13 and fluid water is formed therein. Then, step S4 is performed in which the fluid water from the merging piping 13 flows through the microbubble nozzle 14 to generate a microbubble fluid. Finally, step S5 is performed, i.e. the micro-bubble fluid is injected into the washing chamber, i.e. the micro-bubble fluid is injected into the inner drum 30 and/or the outer drum 40. After step S5 is performed, the control method ends.

Fig. 5 is a flow chart schematically showing a first embodiment of the control method for a washing apparatus of the present invention. In one or more embodiments, as shown in fig. 5, in the configuration of the water intake system 10 of the washing apparatus 1 of the present invention, the second conduit 12 includes a main conduit 124, a first branch 241, a second branch 242, and a third branch 243. When it is desired to wash laundry with a detergent, the control method for the washing apparatus 1 of the present invention starts by first performing step S11, i.e. activating the water controller 111 to let the first pipe 11 water. Simultaneously or subsequently, step S211 is performed, i.e. the switching valve 123 is controlled to bring the main line 124 into communication with the first branch 241. In alternative embodiments, the switching valve 123 may also be controlled to place the main line 124 in communication with the second branch 242 or the third branch 243. Simultaneously or subsequently, step S212 is performed, i.e., the inflation controller 122 is opened to vent the main line 124. In alternative embodiments, this step S212 may also be omitted. Simultaneously or subsequently, step S213 is performed in which the dispenser 121 is activated to pump the treatment agent from the treatment agent cartridge 20 into the main line 124 through the first branch 241 and to pump the treatment agent together with the gas into the merging line 13. At this time, the water in the first line 11 and the treating agent and gas in the main line 124 flow into the merging line 13, respectively. The duration of activation of the water controller 111, the air charge controller 122 and the dispenser 121 may be the same or different. Then, the control method proceeds to step S31, that is, the water from the first line 11 and the treatment agent and gas from the main line 124 flow into the merging line 13, and a mixed fluid is formed therein. Step S41 is then performed in which the mixed fluid from the merging line 13 passes through the microbubble nozzle 14 to generate a mixed microbubble fluid. The mixed fluid contains water, a treating agent and a plurality of bubbles. When the mixed fluid passes through the micro-bubble nozzle 14, the micro-bubble nozzle 14 can cut bubbles therein sufficiently and effectively, so that the mixed fluid contains a large number of micro-bubbles, thereby improving the activity of the laundry treating agent and enhancing the washing effect. Finally, step S51 is performed, i.e., the mixed microbubble fluid is injected into the outer cylinder 40 or the inner cylinder 30. After the execution of step S51, the control method ends, and the washing apparatus 1 washes the laundry using the bubble water containing a large amount of micro bubbles. In alternative embodiments, the washing apparatus 1 of the present invention may also employ such a control method in situations where care is required for the laundry using a softener. Alternatively, the inventive washing apparatus 1 may also employ such a control method in case laundry needs to be treated with a laundry disinfectant or other suitable laundry care agent.

When the laundry is to be rinsed, the control method for the washing apparatus 1 of the present invention starts, and first, step S12 is performed, i.e., the water controller 111 is activated to allow the first pipe 11 to be filled with water. Simultaneously or subsequently, step S221 is performed, i.e. the switching valve 123 is controlled to shut off the communication between the main line 124 and the first branch 241. At this time, the main line 124 is disconnected from the process agent cartridge 20, and no process agent is introduced into the main line 124. Simultaneously or subsequently, step S222 is performed, i.e., the inflation controller 122 is opened to vent the main line 124. Simultaneously or subsequently, step S223 is performed, and the dispenser 121 is activated to pump the gas in the main line 124 to the merging line 13. At this time, the water in the first pipe 11 and the gas in the main pipe 124 of the second pipe 12 flow to the merging pipe 13, respectively. The duration of activation of the water controller 111, the air charge controller 122 and the dispenser 121 may be the same or different. Then, the control method proceeds to step S32, that is, the water from the first pipe 11 and the gas from the main pipe 124 flow into the merging pipe 13 and form bubble water therein. Next, step S42 is performed in which the bubble water from the merging line 13 flows through the microbubble nozzle 14 to generate a microbubble water fluid. When water containing a large number of bubbles passes through the microbubble nozzle 14, the bubbles in the water are sufficiently and effectively cut by the microbubble nozzle 14, forming a large number of microbubbles. Finally, step S52 is performed, in which the fine bubble water is injected into the outer cylinder 40 or the inner cylinder 30. After step S52 is performed, the control method ends. The washing apparatus 1 can obtain a better rinsing effect by washing laundry using bubble water containing a large amount of microbubbles.

Simultaneously or subsequently, step S232 is performed, and the switching valve 123 is controlled to communicate the main line 124 with the first branch 241 for 2 seconds. In alternative embodiments, the switching valve 123 may be open for a duration of 3 seconds or any other suitable duration. At this time, the water in the first line 11 and the treating agent in the main line 124 flow to the merging line 13, respectively. Then, step S233 is performed in which the control switching valve 123 cuts off the communication between the main pipe 124 and the first branch 241. Simultaneously or subsequently, step S234 is performed, i.e., the inflation controller 122 is opened to vent the main line 124 for 2 seconds. In alternative embodiments, the duration of the inflation controller 122 opening may also be 3 seconds or any other suitable length of time. At this time, the water in the first pipe 11 and the gas in the main pipe 124 flow to the merging pipe 13, respectively. Then, step S235 is performed, i.e., the inflation controller 122 is turned off to stop the ventilation into the main line 124. Next, step S236 is performed, in which the above steps S232 to S235 are repeated until the amount of the treatment agent to be administered reaches a predetermined amount. In one or more embodiments, the predetermined dosage is 20 milliliters and the switching valve 123 can pump 1 milliliter of treatment agent into the converging line 13 each time the main line 124 communicates with the first branch 241. After repeating steps S232 to S235 20 times, the amount of the treatment agent to be added reaches a predetermined amount to be added, step S33 is performed in which the water from the first pipe 11 and the fluid from the main pipe 124 flow into the merging pipe 13 and a mixed fluid is formed therein. Then, step S43 is performed in which the mixed fluid from the merging piping 13 flows through the microbubble nozzle 14 to generate a mixed microbubble fluid. Finally, step S53 is performed, i.e., the mixed microbubble fluid is injected into the outer cylinder 40 or the inner cylinder 30. After step S53 is performed, the control method ends. In alternative embodiments, the predetermined dosage may be 40 milliliters, or any other suitable amount. Preferably, the predetermined dose is 15 to 45 ml.

At this time, the water in the first pipe 11, the treating agent in the first extraction pipe 244, and the gas flow to the merging pipe 13, respectively. The duration of activation of the water controller 111, the air charge controller 122 and the dispenser 121 may be the same or different. Then, the control method proceeds to step S34, that is, the water from the first pipe 11 and the treatment agent and gas from the first extraction pipe 244 flow into the merging pipe 13 and form a mixed fluid therein. Next, step S44 is performed in which the mixed fluid from the merging piping 13 flows through the microbubble nozzle 14 to generate a mixed microbubble fluid. Finally, step S54 is performed, i.e., the mixed microbubble fluid is injected into the outer cylinder 40 or the inner cylinder 30. After step S54 is performed, the control method ends. In an alternative embodiment, the inflation controller 122 and dispenser 121 on the second extraction line 245 may also be opened to pump the treating agent in the second receiving chamber of the treating agent cartridge 20 to treat the laundry.

The water controller 111 may be continuously on for 2 minutes, or any other suitable duration. Simultaneously or subsequently, step S251 of intermittently opening the inflation controller 122 on the first extraction line 244 at predetermined time intervals to vent the first extraction line 244 is performed.

In an alternative embodiment, the inflation controller 122 is turned on every 1 second and each turn on lasts for 1 second of inflation time. Alternatively, the inflation controller 122 may be opened once at any suitable time interval and inflated for any suitable period of time.
