Description

Technical Field

[0001] This invention relates to the field of washing technology, specifically to a micro-nano bubble washing device and washing method. Background Technology

[0002] With the continuous development of the social economy and the increasing income of people, consumption concepts have also changed. This has led to the continuous expansion of linen washing services in industries such as hotels, restaurants, and hospitals, while traditional washing machines can no longer meet the washing needs. Tunnel-type washing machines, also known as "laundry dragons," utilize water circulation and filtration technology compared to traditional washing machines, greatly reducing water waste; they can save 60% of water, over 50% of electricity, and 70% of manpower. Furthermore, the hygienic isolation type of laundry dragon has two independent channels for soiled linens and clean linens, effectively preventing cross-contamination and improving cleanliness. However, due to the large washing volume, laundry dragons generally require a large amount of water and detergent for rinsing, and this "mechanical agitation + detergent" washing method has problems with high water consumption and serious environmental impact.

[0003] For example, patent number 202111427412X discloses an integrated washing machine that can effectively remove residual ions from washing water, reduce the dissolved solids content of wastewater after fabric washing, and improve washing quality and efficiency. However, this method still requires the addition of chemical detergents, which not only increases the cost of washing water treatment but also causes serious environmental pollution.

[0004] For example, patent number CN202010308015X discloses a washing method and washing equipment based on micro-nano bubbles. It uses micro-nano bubble water generated by a micro-nano bubble generator to clean and disinfect clothes. Although it can avoid the pollution of chemical detergents, the washing and sterilization effects cannot achieve the expected results.

[0005] With the continuous development of washing technology, micro-nano bubble washing mode has gradually replaced traditional washing mode. In view of this, a micro-nano bubble washing device and washing method are proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a micro / nano bubble washing device and washing method to solve the problems mentioned in the background art.

[0008] Preferably, the pre-wash assembly consists of five pre-wash chambers and a pre-wash water tank. The five pre-wash chambers are connected sequentially from right to left by bolts. The leftmost pre-wash chamber is connected to the pre-wash water tank by a pipeline. The pre-wash chamber is the inlet for linens, micro-nano hydrogen bubble water, and micro-nano ozone bubble water. The pre-wash water tank is used to store impurities after pre-washing.

[0009] Preferably, the main wash assembly consists of six main wash compartments and a main wash water tank. The six main wash compartments are bolted together from right to left. The rightmost main wash compartment is bolted to the leftmost pre-wash compartment. The leftmost pre-wash compartment transports linens to the rightmost main wash compartment for main washing. The leftmost main wash compartment is connected to the main wash water tank via a pipeline. The main wash water tank is used to store impurities after the main wash.

[0010] Preferably, the rinsing assembly consists of five rinsing chambers and a rinsing water tank. The five rinsing chambers are connected by bolts from right to left. The rightmost rinsing chamber is bolted to the leftmost main washing chamber. The leftmost main washing chamber transports linens to the rightmost rinsing chamber for rinsing. The second rinsing chamber from right to left is connected to the rinsing water tank by a pipeline. The rinsing water tank is used to store impurities after rinsing. The leftmost rinsing chamber is the outlet for the linens.

[0011] Preferably, the filter assembly consists of three identical first filter structure, second filter structure and third filter structure, arranged from left to right below the washing machine, including a filter tank, a primary filter, a secondary filter, a chlorine bubble pump, a micro-nano bubble generator and an electrolysis cup. The first filtration structure has a pipeline connecting the pre-filter and the rinsing water tank. The pre-filter, secondary filter, and filter tank are connected by pipelines in sequence. The filter tank, electrolysis cup, micro-nano bubble generator, and chlorine bubble pump are connected by pipelines in sequence to form a loop. The filter tank is connected to the leftmost main wash chamber. The micro-nano bubble generator is connected to the ozone generator. The pre-filter of the filtration device is connected to the main wash water tank. The filter tank of the filtration device is connected to the pre-wash chamber. The pre-filter of the filtration device is connected to the pre-wash water tank. The filter tank of the filtration device is connected to the micro-nano bubble generator.

[0012] Preferably, the ozone and micro / nano bubble generating device includes an ozone generator and a micro / nano bubble generator, wherein the ozone generator is connected to three nano bubble generator pipelines of the filter assembly, and the micro / nano bubble generator is connected to a water storage tank pipeline.

[0013] Preferably, the water supply assembly includes a water storage tank, an electrolysis tank, a micro-nano bubble generator, and a water storage device; The water storage device includes a second water tank, a sensing system, a first hydrogen emitter, a second hydrogen emitter, and a heater. The sensor system includes a temperature sensor, an ORP sensor, a pH sensor, and a level sensor, which are used to measure the water temperature, ORP, pH, and level information in the second water tank, respectively. The water tank is connected to the second water tank via pipelines. The water tank, the electrolysis tank, and the water tank are connected to the water tank via pipelines in sequence to form a loop. The first hydrogen emitter and the second hydrogen emitter are respectively bolted to the top right side of the second water tank and are in communication with each other. The sensor system is fixedly connected to the second water tank. The top of the second water tank is connected to the leftmost pre-wash chamber, the rightmost pre-wash chamber, and an external water source pipeline, respectively. The left side of the second water tank is fixedly connected to the heater, which is used to heat the micro-nano bubble washing water in the second water tank.

[0014] A washing method for a micro / nano bubble washing device includes the following steps: Step 1: Linen and clothing enter from the pre-wash compartment; Step 2: Inject micro-nano ozone and hydrogen bubble water; Clean water enters the second water storage tank through a pipeline, and then is transported from the second water storage tank to the electrolysis tank to electrolyze and produce water containing hydrogen gas and hydrogen ions. After passing through the micro-nano bubble generator, micro-nano hydrogen bubble water is produced and returns to the second water storage tank to circulate, thus improving the quality and production efficiency of micro-nano hydrogen bubble water. Then, the heater heats the micro-nano bubble washing water in the water storage tank to a washing temperature of 300-500 degrees Celsius. At this time, the micro-nano ozone bubble water transported from the water storage tank to the second water storage tank is mixed with the micro-nano hydrogen bubble water and injected into the rightmost pre-washing chamber. Step 3: After pre-washing, drain the water containing impurities and proceed to the main wash; The linens are washed from the rightmost pre-wash compartment to the leftmost pre-wash compartment. Since the linens have been washed, the water contains impurities. The valve is opened to discharge the impurity water into the pre-wash water tank. After the discharge is completed, the valve is closed, and micro-nano ozone and hydrogen bubble water are introduced from the second water storage tank into the leftmost pre-wash compartment. Then the linens and bubble water are transferred together to the main wash compartment. Step 4: After the main wash is complete, drain the water containing impurities and proceed to the rinsing stage; After the main wash is completed, the linens are moved from the rightmost main wash compartment to the leftmost main wash compartment. The valve is opened to drain the impurities into the main wash water tank. After draining, the valve is closed, and filtered water is introduced from the filter tank in the first filter structure into the leftmost main wash compartment. Then, the linens and air bubbles are moved together to the rightmost rinsing compartment. Step 5: Rinse thoroughly, drain the water containing impurities, and the washing process is complete; After rinsing is complete, the linens are moved from the rightmost rinsing compartment to the rinsing compartment connected to the main wash tank. The valve is opened to drain the impurities into the main wash tank. After draining, the valve is closed, and the linens are moved to the leftmost rinsing compartment. The washing is now complete.

[0015] The water recycling process of the micro-nano bubble scrubbing dragon device includes the following steps: Taking the water circulation of the first filtration structure as an example, the rinsing water tank transports the rinsing impurity water to the primary filter for preliminary coarse filtration through pipelines. Then, the coarsely filtered impurity water is transported to the secondary filter for secondary fine filtration. Finally, the filtered water is transported to the filter water tank. The filtered water in the filter water tank is transported to the chlorination pump for chlorination. The nano bubble generator then converts the chlorinated filtered water into micro-nano bubble water. At this time, the ozone generator transports the generated ozone through pipelines to the micro-nano bubble generator to generate micro-nano ozone bubble water. The electrolysis pump electrolyzes the filtered water to generate hydrogen ions, thereby forming micro-nano ozone and hydrogen bubble filtered water. Finally, it returns to the filter water tank to form a loop, which improves the quality and production efficiency of the filtered micro-nano ozone and hydrogen bubble filtered water. Afterward, the filter water tank transports the micro-nano ozone and hydrogen bubble filtered water to the leftmost main wash chamber for reuse. Unlike the first filtration structure, the main wash water tank delivers impurity water to the pre-filter of the second filtration structure, and the filter water tank of the second filtration device delivers micro-nano ozone and hydrogen bubble filtered water to the pre-wash chamber for recycling. Unlike the first filtration structure, the pre-wash water tank transports impurity water to the primary filter of the third filtration structure. The third filtration structure's filter tank then transports the micro-nano ozone and hydrogen bubble filtered water to the micro-nano bubble generator to further generate micro-nano ozone and hydrogen bubbles, increasing the number of micro-nano bubbles. This water is then transported to the storage tank, where it is transferred to the second storage tank. From there, it is sent to the electrolysis tank for electrolysis to generate hydrogen gas and hydrogen ions, increasing the hydrogen ion content of the bubble water. This water is then transported back to the micro-nano bubble generator to further increase the number of micro-nano bubbles. The water then returns to the second water tank, forming a loop circulation, which improves the quality and efficiency of the micro-nano bubble washing water. At the same time, the hydrogen gas at the top of the second water tank is discharged from the first and second hydrogen exhaust devices, improving the safety of the operation. The heater heats the micro-nano bubble washing water in the second water tank to the optimal washing temperature of 300-500 degrees Celsius. The sensor system measures the water temperature, ORP, pH and liquid level in the second water tank in real time. Finally, the micro-nano ozone and hydrogen bubble water in the second water tank is transported to the leftmost and rightmost pre-wash chambers to form a recycling system.

[0016] The micro-nano bubble washing device and washing method proposed in this invention have the following advantages: (1) The filter assembly of the present invention can filter impurity water coarsely and finely and recycle it, which improves the washing efficiency of the washing machine and reduces water consumption, and has the advantages of energy saving, high efficiency and environmental protection.

[0017] (2) The first hydrogen emitter and the second hydrogen emitter of the present invention can safely discharge the hydrogen generated by electrolysis. While improving the safety of the washing operation, they can detect the parameters of the bubble water in real time, including ORP value, pH value, temperature and liquid level. The heater can heat the temperature of the micro-nano bubble washing water in the water tank to the optimal temperature for washing effect (300-500 degrees) to obtain micro-nano bubble water with the best washing effect.

[0018] In summary, the micro-nano ozone and hydrogen bubble water of this invention have the advantages of disinfection, sterilization, and good washing effect compared with traditional detergents. Attached Figure Description
