Detailed Description
As shown in fig. 1 to 8, in a household appliance, especially a dishwasher, a washing machine or a dryer, the present technical solution can generate and circulate plasma-activated water to sterilize most of a humid space in the household appliance, such as a humid space in the household appliance, and prevent bacteria and mold from growing. In particular, the object of the present solution is to integrate a plasma generator in a household appliance, in particular a plasma generator that can be integrated in the liquid circulation circuit of a household appliance, so as to be able to generate plasma-activated water that can circulate in the liquid circulation circuit during the normal operation of the household appliance, or in a separate purification procedure independent of the normal operation.
The technical scheme that this application provided does, domestic appliance includes liquid circulation circuit, and liquid circulation circuit includes plasma generator 16, at least one driving pump, and the driving pump provides operating power for liquid circulation circuit's working medium, and plasma generator 16 can produce cold ordinary pressure plasma, and liquid circulation circuit's working medium carries out plasma activation through plasma generator. The plasma generator is arranged through a liquid circulation loop of the household appliance, the plasma generator can generate cold normal-pressure plasma, working media of the liquid circulation loop are subjected to plasma activation through the plasma generator, and the working media are exemplified by water.
As shown in fig. 1, one embodiment of the plasma activation process, the plasma reactant is formed in the gas phase and dissolved in water at the interface of the plasma and water; the plasma generator 16 is a non-high temperature normal pressure plasma generator, and can generate plasma activated water, which circulates in the liquid circulation loop during the life of active substances in the water, so that the entire internal water guide space of the household appliance can be sufficiently purified, and the water can be activated and circulated in a liquid phase or gas phase form.
Fig. 2 shows an embodiment in which the plasma generator 16 is integrated in the inlet and/or outlet section of the drive pump 14; alternatively, the plasma generator 16 is installed at an inlet portion and/or an outlet portion of the driving pump 14, one port of the plasma generator 16 is communicated with one of the inlet portion and the outlet portion of the driving pump, and the other port of the plasma generator 16 is communicated with the other of the inlet portion and the outlet portion of the driving pump. Specifically, the plasma generator 16 is integrated in the suction port portion and/or the discharge portion of the circulation pump 14, or the plasma generator 16 is mounted on the suction port portion and/or the discharge portion of the circulation pump 14, one port of the plasma generator 16 is communicated with one of the suction port portion and the discharge portion of the circulation pump, and the other port of the plasma generator 16 is communicated with the other of the suction port portion and the discharge portion of the driving pump. The household appliance or the liquid circulation circuit further comprises a liquid storage device 3, the plasma generator 16 is integrated with a supply pipeline of the liquid storage device 3, and the liquid storage device 3 can store clean water and/or washing water; alternatively, the household appliance or the liquid circulation loop comprises a water supply tank, and a water leakage protection system communicated with the water supply tank, wherein the plasma generator 16 is installed or integrated at the downstream of the water leakage protection system;
in particular, fig. 2 is a schematic view of a liquid circulation circuit of the dishwasher 1, fresh water being supplied to the dishwasher through an inlet valve 4, after which inlet valve 4 a safety air gap 5 is arranged, the fresh water entering a tank 3 for storing incoming water via a supply line 6. The ventilation line 7 allows air to enter the tank 3. Water passes from the tank through the inlet switch 13 and is directed to the waste pump 8 or drive pump 14. The plasma generator 16 is integrated in the inlet or outlet portion of the drive pump 14. This arrangement allows the active substance to be generated in the water pumped through the hydronic circuit, thereby providing a continuous distribution of the active substance throughout the hydronic circuit. The rotating speed of the pump can be adjusted according to the reaction speed of the plasma generator to achieve the required volume flow so as to optimize the performance. The plasma-activated water is pumped into the heating device 15 and enters the water supply line supplying the spray arm sets 10, 11 via the circulating water switch 9, the circulating water switch 9 distributing the plasma-activated water throughout the interior space of the dishwasher. The water is then collected in the water tank 2, passed again through the water supply switch 13, and either re-routed to the liquid circulation circuit or discharged via the waste water pump 8 into the waste water line 12.
Referring to the embodiment shown in fig. 3, the household appliance or the liquid circulation loop comprises a fresh water supply line 6, in which the plasma generator 16 is mounted or integrated, an embodiment of the arrangement of the plasma generator in the liquid circulation loop is illustrated integrated at the fresh water supply line, which is also the supply line of the fresh water and/or wash water storage tank, the plasma generator being integrated in the fresh water supply line 6. This arrangement allows the water to be purified before it enters the liquid circulation circuit of the household appliance and prevents the biomass from growing.
If the water is activated or circulated in the gas phase, a steam generation circuit can be provided in the household appliance or in the liquid circulation circuit, the plasma generator 16 being mounted or integrated in the inlet region of the steam generation circuit. In the schematic illustration of fig. 4, a further embodiment of the arrangement of the plasma generator in the liquid circulation circuit is illustrated, the plasma generator being integrated in the line for supplying water to the spray arm set, the plasma generator being integrated in the lines 10, 11 for supplying water to the spray arm set. At this time, the spray arm groups 10, 11 may function as a purge unit. When water is supplied to the spray arm set 10 and the plasma generator is operated, the plasma-activated water is efficiently sprayed and distributed into the internal space of the household appliance via the spray arm set. Since the water is activated just before spraying, it still contains a high concentration of active substance.
Alternatively, the household appliance or the liquid circulation circuit comprises a water supply switching line which is arranged separately, and the plasma generator 16 is integrated with the water supply switching lines 10, 11.
The plasma generator is configured to activate water flowing through and continuously circulating in a liquid circulation loop component of the household appliance. The plasma generator may be integrated in a water conduit in the liquid circulation loop, wherein all or part of the water flowing through the conduit during operation of the drive pump of the domestic appliance passes through the plasma generator. For example, the flow of water and/or air through the plasma generator may be adjusted according to the reaction rate of the plasma generator.
Although the concentration of active substances in water activated by a non-high temperature and normal pressure plasma generator is not as high as that of active substances in water activated and heated by high temperature plasma discharge, these active substances provide sufficient antibacterial activity within about 15 minutes after their generation, sufficient to disinfect the entire inner water-guiding space of a conventional household appliance, such as a dishwasher, a washing machine, or a dryer.
Since non-high temperature atmospheric pressure plasma can be generated in air at atmospheric pressure, complex, expensive vacuum techniques can be avoided. The temperature of the non-high temperature plasma can be adjusted to be as low as room temperature and thus does not affect the temperature of the water during the activation process.
In view of the life of the active species in the plasma-activated water, a liquid circulation loop component may be used to circulate the plasma-activated water to achieve the desired disinfection effect. The operating time of the plasma generator can be adapted to the respective operating state of the household appliance and adjusted in dependence on the amount of fluid flowing through the circulation circuit for controlling the sterilization. For example, the sterilization can be carried out during a normal operating program of the household appliance (for example during rinsing with fresh water), or can be carried out in a separate sterilization program independently of the normal operating program of the household appliance.
The plasma generator is for example integrated in a water pipe in the liquid circulation circuit, so that all or part of the water flowing through the conduit passes through the plasma generator during operation of the drive pump of the household appliance. Air may be supplied to the plasma generator via a snorkel for plasma generation, if desired.
The plasma generator used in the context of the present solution comprises a reaction chamber with at least one joint water/gas inlet or two independent water/gas inlets and at least one outlet, and electrodes for generating an electric field within the reaction chamber. The inlet is configured to receive water from a liquid circulation loop of the household appliance and the outlet is configured to return plasma-activated water to the liquid circulation loop of the household appliance. In addition, the plasma generator described above may include means for controlling the volumetric flow of water and/or air through the generator, such as by simultaneously controlling the proportions of water and air present in the reaction chamber. The or each of the inlets may further comprise means for evaporating water from the reaction chamber.
The plasma generator used in the technical scheme is configured to generate cold plasma, and the cold plasma does not need to heat water additionally in the activation process. The plasma generator may be integrated at a specific location in the household appliance, or more than one plasma generator may be integrated at two or more locations as described below. The present solution therefore also relates to a household appliance in which two or more plasma generators are integrated at different locations of the liquid circulation circuit.
In a further exemplary embodiment of the domestic appliance, the plasma generator described above is integrated into the fresh water supply line. Fresh water is typically delivered from a domestic water supply point to the domestic appliance through water pipes in the wall. The water duct is connected to the household appliance and allows water to enter through the fresh water supply line when the inlet valve is open. The integration of the plasma generator at the fresh water supply line downstream of the inlet valve enables to ensure that the water is purified before entering the liquid circulation circuit of the household appliance. This arrangement prevents the ingress of any potential biological contaminants that might cause biomass growth within the appliance when the plasma generator is operating during water ingress.
According to a further exemplary embodiment of the household appliance, the plasma generator is integrated in a water supply line of the fresh water and/or wash water storage tank. Household appliances usually have a tank for storing fresh or wash water, which has been used in the wash cycle, but which is not yet dirty to such an extent that it needs to be disposed of immediately, but is reusable (e.g. rinse water). The storage tank temporarily stores water, which is gradually fed into the liquid circulation circuit according to an operation program. If the plasma generator is integrated in the water supply line of the storage tank, biological contaminants can be prevented from being introduced into the storage tank since the intake water is purified. This arrangement is particularly efficient because microorganisms entering the tank may develop a biofilm, especially when the water is stored and thus somewhat stagnant.
In an exemplary embodiment of the domestic appliance, the plasma generator is integrated in the inlet region of the steam generation line. If the domestic appliance has a steam generator, it is advantageous to integrate the plasma generator in the region of the inlet of the steam generation line. In this arrangement, the plasma-activated water becomes steam immediately after being generated. The uniform distribution of the activated water droplets in the form of steam enables particularly efficient disinfection of the interior space of the household appliance. Steam can fill the interior space and thus reach locations that are otherwise difficult to reach.
In a further embodiment of the household appliance, the plasma generator is integrated downstream of the water leakage prevention system of the water supply tank. Integrating the plasma generator into the main installation point of the liquid circulation circuit enables efficient distribution of the activated water according to the operating program.
In another embodiment, the household appliance or liquid circulation circuit comprises a water softening device, downstream of the outlet of which the plasma generator 16 is integrated, which in most household appliances removes ions, such as Ca2+ and Mg2+, from the water entering the household appliance. These ions can cause calcification, long-term damage to household appliances, and interact with soaps, reducing their detergency. If the plasma generator is integrated downstream of the outlet of the water softening device, then at this point the water to be activated has just been softened, i.e. has been freed of hardening ions. The activation is particularly efficient as it does not interfere with the production of active species in the water.
Referring to another embodiment shown in fig. 5, the household appliance or liquid circulation loop comprises a metering device, with which the plasma generator 16 is at least partially integrated; if the plasma generator is integrated in the metering device, the delivery of the activated water to the liquid circulation circuit can be controlled in accordance with the operating program.
In a further exemplary embodiment of the domestic appliance, the plasma generator described above is integrated in a separate water supply switching line. In household appliances, the water supply switch allows water to be supplied to a separate line (e.g., a spray arm in a dishwasher). The integration of the plasma generator in the spray arm enables a particularly fast and efficient distribution of the plasma-activated water, since the water is sprayed into a large space inside the household appliance. The separate line integrated with the plasma generator can also be used as a purge line for purging the interior space of the household appliance independently of the normal operating procedure. In particular, the plasma generator is integrated in a conduit for supplying water to the top spray arm of a dishwasher or the like.
Referring to fig. 6 and 7, in another embodiment, a user can see the plasma generator from the outside when operating the plasma generator. This arrangement allows visual inspection of whether the plasma generator is operating and indicates that water is activated when a flickering plasma discharge is observed. The household appliance comprises a visible window portion, the visible window portion at least comprises a transparent or semitransparent window plate, the plasma generator 16 is arranged corresponding to the visible window portion, and when the plasma generator 16 operates, a user can see the plasma generator 16 from the outside of the household appliance through the visible window portion.
The present technical solution also relates to a process for operating a household appliance, in particular the aforementioned household appliance, in which plasma-activated water is generated and circulated in a liquid circulation circuit. A household appliance with a liquid circulation circuit comprises a drive pump for circulating water according to an operating program during operation of the household appliance. The integration of a plasma generator at the inlet or outlet portion of the drive pump allows the generation of active species in the water pumped through the hydronic circuit and the continuous distribution of the active species throughout the hydronic circuit. The rotational speed of the pump can be adjusted in accordance with the reaction speed of the plasma generator to achieve an optimum volumetric flow rate.
The technical scheme provided by the application further comprises an operation control method, wherein the operation control method is used for controlling the household appliance to operate and comprises the following steps: the operation of the liquid circulation loop of the household appliance is controlled, the operation mode comprises a plasma activation stage, in the plasma activation stage, the working medium of the liquid circulation loop is controlled to pass through a passage where the plasma generator 16 is located, and the working medium of the liquid circulation loop is subjected to plasma activation, so that the liquid circulation loop generates plasma activated water and circulates.
According to the described process for operating a household appliance having a liquid circulation circuit and a plasma generator, circulating water is activated while flowing through the liquid circulation circuit and through the plasma generator. This process allows the plasma-activated water generated at a specific location of the liquid circulation loop to be distributed into most or even all of the water-conducting and humid interior space of the household appliance during the lifetime of the active species of the plasma-activated water. Thus, the entire liquid circulation loop can be purified using plasma activated water without introducing potentially hazardous chemicals and then disposing of such chemicals. Due to the use of a cold atmospheric plasma generator, the operating temperature thereof can be lower than 60 ℃, such as lower than 40 ℃, particularly such as lower than 30 ℃, and does not interfere with the operating temperature of the household appliance. Thus, the plasma generator may be operated during a normal operation procedure of the household appliance. Such as during the intake of fresh water or during the rinsing phase of a cycle in which fresh or slightly dirty water is being circulated.
When the household appliance has no washing or drying load, the driving pump in the liquid circulation loop is controlled to work, and at the moment, the clean water circulates in the household appliance to perform a plasma activation stage, so that the plasma activated water is generated and circulated.
The operation of the liquid circulation circuit and the plasma generator can be realized such that the normal operation procedures of the household appliance, i.e. the washing and drying of the articles, are carried out independently of the plasma generator. At this time, the plasma generator is operated in a special cleaning process, i.e., when there are no articles to be washed or dried in the household appliance. In such a purification procedure, for example, fresh water is introduced into the liquid circulation circuit and activated and circulated so that the fresh water reaches all parts of the liquid circulation circuit in 15 minutes or less. The cycle may be repeated multiple times while the water is repeatedly activated to achieve optimal purification.
It should be noted that: although the present invention has been described in detail with reference to the above-mentioned embodiments, it should be understood by those skilled in the art that the present invention may be modified and equivalents may be substituted for those skilled in the art, and all technical solutions and modifications that do not depart from the spirit and scope of the present invention should be covered by the claims of the present invention.
