Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning technology, and in particular to a descaling system and a dishwasher. Background Technology
[0002] Scale buildup poses a significant threat to dishwashers. It easily adheres to the heating element, wash pump, and water pipes, potentially causing malfunctions and even damage. Dishwashers typically incorporate a water softener to soften the tap water entering the dishwasher, preventing scale buildup from prolonged use of hard water. Water softeners primarily use resin to replace calcium and magnesium ions in hard water, forming water-soluble compounds. However, after a period of use, the sodium ions on the resin's surface are depleted, requiring timely replenishment with specialized salt. Many users forget to add this salt, leading to further scale buildup. Utility Model Content
[0003] Therefore, it is necessary to provide a descaling system and dishwasher to address the problem of limescale buildup caused by users not adding salt for a long time.
[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0005] In a first aspect, embodiments of this application provide a descaling system, comprising:
[0006] A cleaning assembly, comprising a washing pump for delivering cleaning fluid to the object to be cleaned;
[0007] A detection device is installed on the end side of the washing pump and is used to monitor the water pressure value P on the end side of the washing pump;
[0008] A descaling component, which is connected to the cleaning component, and the descaling component stores a descaling agent solution;
[0009] When the detection element monitors a water pressure value P ≤ a preset water pressure value P0, the descaling component is controlled to deliver the descaling agent solution to the cleaning component.
[0010] With the above design, when scale is present in the water circuit, the descaling component automatically delivers a descaling agent solution to the cleaning component.
[0011] In one embodiment of the first aspect, the descaling assembly includes a descaling agent container, a dispensing device, and a water tank. The descaling agent container contains descaling agent and has a discharge port. The dispensing device is located at the discharge port and is used to control the discharge of the descaling agent. The water tank is connected to both the discharge port and the cleaning assembly. The descaling agent dissolves in the water tank to form the descaling agent solution.
[0012] With the above design, the dispenser can automatically control the opening and closing of the discharge port of the descaling agent container according to the descaling requirements, so as to realize the automatic feeding of the descaling agent.
[0013] In one embodiment of the first aspect, the descaling assembly further includes a descaling pump disposed between the water tank and the cleaning assembly.
[0014] With the above design, the descaling pump can continuously deliver the descaling agent solution in the water tank to the water cup, thereby increasing the output rate of the descaling agent and improving the descaling effect.
[0015] In one embodiment of the first aspect, the descaling assembly further includes a float electrically connected to the descaling pump, wherein the descaling pump is controlled to stop operating after the float descends to the bottom of the water tank.
[0016] With the above design, when the float is at the bottom of the water tank, the descaling pump determines that the liquid in the water tank is empty and stops operating, thereby avoiding damage caused by the continuous operation of the descaling pump after the water tank is emptied.
[0017] In one embodiment of the first aspect, the descaling system further includes a water supply component connected to both the cleaning component and the descaling component.
[0018] With the above design, only one water source is needed to simultaneously supply liquid to the water tank and the water cup.
[0019] In one embodiment of the first aspect, the water supply assembly includes an inlet valve and a three-way valve, the three ports of which are respectively connected to the inlet valve, the cleaning assembly, and the descaling assembly.
[0020] With the above design, the three-way valve can be connected to both the water tank and the water cup at the same time. While satisfying the cleaning operation, some liquid enters the water tank and mixes with the descaling agent to form a solution, which is then output to the water cup by the descaling pump.
[0021] In one embodiment of the first aspect, the water supply assembly further includes a flow meter disposed between the inlet valve and the three-way valve.
[0022] The above design allows for reasonable control of the water supply rate, thereby improving the system's control accuracy.
[0023] In one embodiment of the first aspect, the cleaning assembly further includes a water cup and a drain pump, the water cup being connected to the washing pump, the drain pump, and the descaling assembly, respectively.
[0024] With the above design, after cleaning, the drain pump completely drains the liquid in the water cup, preventing residual water inside the water cup from causing bacterial growth or corrosion damage to the container.
[0025] In one embodiment of the first aspect, the cleaning assembly further includes a spray arm connected to the output of the washing pump.
[0026] With the above design, the spray arm generates a spray that is directly sprayed onto the tableware in the dish rack, improving the cleaning effect.
[0027] Secondly, embodiments of this application also provide a dishwasher, including the descaling system described in any of the above embodiments.
[0028] The above design enables automatic addition of descaling agent, ensures water pressure, and improves the cleaning effect of tableware.
[0029] Thirdly, this application also provides a descaling method, applied to the descaling system or dishwasher described in any of the above embodiments, the descaling method comprising:
[0030] Control the water inlet valve to open and supply clean water to the water cup through the three-way valve;
[0031] The washing pump is controlled to continuously spray clean water from the water cup onto the object to be washed, and the detection device monitors the water pressure value P at the end of the washing pump in real time.
[0032] When the water pressure value P ≤ the preset water pressure value P0, the three-way valve is controlled to connect with the water tank and supply clean water to the water tank. The dispensing device is controlled to open, and the descaling agent in the descaling agent container is discharged into the water tank and mixed with the clean water to form the descaling agent solution.
[0033] The descaling pump is controlled to deliver the descaling agent solution to the water cup, and the washing pump continuously draws liquid from the water cup, so that the descaling agent solution can perform descaling and cleaning of the water system;
[0034] When the water pressure value P > the preset water pressure value P0, the three-way valve is disconnected from the water tank, the dispenser is closed, and the descaling pump stops operating after pumping out the descaling agent solution in the water tank.
[0035] Through the above design, the detection element and the descaling component work together to automatically deliver the descaling agent to the dishwasher's water circuit for descaling and cleaning, eliminating the need for manual salt addition, improving user experience, and extending the dishwasher's lifespan.
[0036] Compared to related technologies, the advantages of this application are as follows: This application provides a descaling system and a dishwasher, which can be used for descaling the water circuit of a dishwasher. The descaling system includes a cleaning component, a detection element, and a descaling component. The cleaning component has a washing pump for delivering cleaning solution to the items to be cleaned, for internal cleaning of the dishwasher. The detection element is installed on the end side of the washing pump and monitors the water pressure value P at the end side of the washing pump in real time. When the water pressure value P ≤ a preset water pressure value P0, the descaling component is controlled to deliver descaling agent solution to the cleaning component. In this way, through the cooperation of the detection element and the descaling component, descaling agent can be automatically delivered to the dishwasher's water circuit for descaling and cleaning, eliminating the need for manual addition of salt, improving the user experience, and extending the service life of the dishwasher.

[0053] In related technologies, while dishwasher water softeners can soften hard water, they often require the addition of salt as a consumable to replace the resin and maintain their softening ability. Salt, as a consumable, does not play a decisive role in the washing effect. Although the machine has a low salt indicator light, since low salt does not affect machine operation, users may not add salt during use, leading to limescale buildup and potential damage to the dishwasher.
[0054] See Figure 1 As shown, to improve the above-mentioned problems, embodiments of this application provide a descaling system 100 for cleaning scale in water circuits, specifically for use in the cleaning water circuit of a dishwasher. The descaling system 100 can automatically add descaling agent to clean the water circuits, eliminating the need for manual salt addition, thus improving user experience and extending the dishwasher's lifespan.
[0055] It should be noted that the descaling system 100 provided in this application is not limited to applications in dishwashers, but can also be applied to water-using appliances such as water heaters, humidifiers, and water purifiers. For ease of understanding, this application uses a dishwasher as an example to illustrate the application scenario of the descaling system 100.
[0056] Specifically, the descaling system 100 includes a cleaning component 110, a detection element, and a descaling component 120. The cleaning component 110 delivers cleaning fluid into the dishwasher to clean the dishes. The detection element is located in the water path of the cleaning component 110 to monitor the water pressure P in real time, thereby determining the level of scale accumulation. The descaling component 120 is electrically connected to the detection element, automatically delivering a descaling agent solution to the cleaning component 110 when scale is present in the water path.
[0057] It should be noted that the principle for judging the scale accumulation in this embodiment is as follows: as the scale increases, the water pressure P in the water circuit decreases, thereby setting a preset normal water pressure P0. When the water pressure P ≤ the preset water pressure P0, the water circuit reaches the descaling condition, and the descaling component 120 delivers the descaling agent solution.
[0058] Continue reading Figure 2 As shown, exemplarily, the dishwasher includes an inner tub 200 for washing dishes, with a dish rack 300 disposed inside, on which dishes are placed. The washing assembly 110 includes a washing pump 111, which sprays washing liquid into the inner tub 200 to wash the dishes placed on the dish rack 300.
[0059] In some embodiments, the cleaning assembly 110 further includes a water cup 112 and a drain pump 113, wherein the water cup 112 is connected to the washing pump 111, the drain pump 113, and the descaling assembly 120, respectively.
[0060] Specifically, the water cup 112 stores cleaning fluid, and one side of it is connected to the input pipe of the washing pump 111. The output of the washing pump 111 is connected to the inner tank 200, thereby outputting the cleaning fluid in the water cup 112 to the tableware in the dish rack 300 for cleaning. The drain pump 113 is connected to the bottom of the water cup 112, so that the liquid in the water cup 112 can be completely drained after cleaning, avoiding residual water in the water cup 112 from causing bacterial growth or corrosion damage to the container. In addition, the water cup 112 is also connected to the descaling component 120. When descaling is required, the water cup 112 receives descaling agent solution from the descaling component 120, and the washing pump 111 draws the descaling agent through the cleaning water path to dissolve the scale in the water path and ensure the output pressure of the washing pump 111. By connecting the water cup 112 to the washing pump 111 and the descaling component 120 respectively, the water cup 112 can effectively store the descaling agent solution from the descaling component 120 during the descaling process. With the continuous pumping of the washing pump 111, the water circuit can be effectively cleaned of scale while meeting the cleaning requirements.
[0061] Furthermore, the cleaning assembly 110 also includes a spray arm connected to the output end of the washing pump 111. For example, the spray arm is mounted below the dish rack 300, and has multiple spray nozzles on the side closest to the dish rack 300. Thus, with the spray arm connected to the output end of the washing pump 111, the washing pump 111 continuously outputs cleaning liquid to the spray arm, forming a spray that directly hits the dishes in the dish rack 300, improving the cleaning effect.
[0062] Preferably, the water cup 112 is located on the bottom side of the inner tank 200, and its top is connected to the inner tank 200, so as to receive the cleaning liquid sprayed into the inner tank 200 by the spray arm, realizing the recycling of the cleaning liquid and improving resource utilization. Furthermore, the washing pump 111 is connected to the bottom side of the water cup 112, thereby ensuring the water supply pressure of the washing pump 111 and reducing the impact of scum on the washing pump 111 during the washing process.
[0063] In some embodiments, the water cup 112 and the inner liner 200 are integrally formed to simplify the overall structure. Of course, in other embodiments, the water cup 112 can also be detached from the inner liner 200 for easier maintenance of each component.
[0064] In this embodiment, the detection element can be a pressure sensor, used to provide feedback on the water pressure in the water circuit. The detection element is installed on the end side of the washing pump 111 and monitors the water pressure value P at the end side of the washing pump 111. It can be understood that the end side of the washing pump 111 can be an output end or an input end. In some cases, there may be a certain deviation between the water pressure values at the output end and the input end. Therefore, the specific value of the preset water pressure value P0 can be adjusted accordingly to assess the scale condition of the water circuit system.
[0065] Continue reading Figure 3 As shown, in some embodiments, the descaling assembly 120 includes a descaling agent container 121, a dispensing device 122, and a water tank 123. The descaling agent container 121 contains descaling agent and has a discharge port 1211. The dispensing device 122 is located at the discharge port 1211 and is used to control the discharge of the descaling agent. The water tank 123 is connected to both the discharge port 1211 and the cleaning assembly 110. The descaling agent dissolves in the water tank 123 to form a descaling agent solution.
[0066] For example, the descaling agent can be composed of citric acid. Citric acid (C6H8O7) reacts with scale to form water-soluble CaC6H5O7 and MgC6H5O7, which remain in the water cup 112 during the washing process and are discharged from the dishwasher via the drain pump 113 after washing. The dispenser 122 can automatically control the opening and closing of the discharge port 1211 of the descaling agent container 121 according to the descaling requirements, thereby achieving automatic dispensing of the descaling agent. After the descaling agent falls into the water tank 123, it mixes and dissolves with the water in the tank 123 to form a solution, which is then output to the water cup 112 through a pipeline.
[0067] Furthermore, the descaling assembly 120 also includes a descaling pump 124, which is disposed between the water tank 123 and the cleaning assembly 110. During the descaling process, the descaling pump 124 continuously delivers the descaling agent solution in the water tank 123 to the water cup 112 to increase the output rate of the descaling agent and improve the descaling effect.
[0068] Furthermore, the descaling assembly 120 also includes a float that is electrically connected to the descaling pump 124. After the float descends to the bottom of the water tank 123, the descaling pump 124 is controlled to stop operating.
[0069] Specifically, the float can acquire the water level signal. After the descaling operation stops, since the solution still remains in the water tank 123, the descaling pump 124 needs to continue pumping the descaling agent solution from the water tank 123. In this way, the water level in the water tank 123 can be obtained through the float. When the float is at the bottom of the water tank 123, the descaling pump 124 determines that the liquid in the water tank 123 is empty and stops the operation, thereby avoiding damage caused by the descaling pump 124 continuing to operate after the water tank is emptied.
[0070] In some embodiments, the descaling system 100 further includes a water supply assembly 130, which is connected to the cleaning assembly 110 and the descaling assembly 120 respectively. For example, the water supply assembly 130 can be connected to both the water tank 123 and the water cup 112 simultaneously, so that only one water source is needed to supply liquid to both the water tank 123 and the water cup 112 at the same time.
[0071] Continue reading Figure 4 As shown, the water supply assembly 130 further includes an inlet valve 131 and a three-way valve 132, with the three ports of the three-way valve 132 connected to the inlet valve 131, the cleaning assembly 110, and the descaling assembly 120, respectively.
[0072] Specifically, the inlet valve 131 is connected to one port of the three-way valve 132 via a pipeline, and automatically controls the water supply to the three-way valve 132. The other two ports of the three-way valve 132 are connected to the water tank 123 and the water cup 112, respectively. When only cleaning is required, the end of the three-way valve 132 connected to the water tank 123 is closed, and liquid is only supplied to the water cup 112 to ensure the cleaning of the tableware. When descaling is required, the three-way valve 132 is connected to both the water tank 123 and the water cup 112. While satisfying the cleaning operation, some liquid enters the water tank 123 to mix with the descaling agent to form a solution, which is then output to the water cup 112 via the descaling pump 124.
[0073] Furthermore, the water supply assembly 130 also includes a flow meter 133, which is located between the inlet valve 131 and the three-way valve 132. By using the flow meter 133, the water supply rate can be reasonably controlled, thereby improving the control accuracy of the system.
[0074] Understandably, the descaling system 100 provided in this application also includes a control component for automatic system operation. For example, the control component may be a central processing chip, electrically connected to each electrical component, thereby sending operation commands to each component. The control component obtains the water pressure value P of the detection element through an internally programmed sequence, thereby assessing the scale condition in the water circuit and controlling the start and stop of each valve and the descaling pump 124.
[0075] Embodiments of this application also provide a dishwasher, including the descaling system 100 of any of the above embodiments.
[0076] This embodiment has the descaling system 100 of any of the above embodiments, and therefore has all the beneficial effects of the descaling system 100 of any of the above embodiments, which will not be described in detail here.
[0077] See Figure 5 As shown, embodiments of this application also provide a descaling method, which is applied to the descaling system 100 or dishwasher in any of the above embodiments.
[0078] Descaling methods include:
[0079] S10, control the water inlet valve 131 to open, and supply clean water to the water cup 112 through the three-way valve 132.
[0080] Specifically, during the dishwasher's cleaning operation, the water inlet valve 131 is opened, and the three-way valve 132 is connected to the water cup 112 to supply clean water to the water cup 112. When the water level reaches the set height, the water inlet valve 131 can be closed to stop the supply of clean water.
[0081] S20, the washing pump 111 is controlled to continuously spray clean water from the water cup 112 onto the object to be washed, and the detection device monitors the water pressure value P at the end of the washing pump 111 in real time.
[0082] Specifically, the washing pump 111 sprays clean water from the water cup 112 onto the dish rack 300 through the spray arm to clean the tableware. As the water flows during the washing process, scale can easily accumulate in the pipes, which in turn affects the water pressure. The monitoring device monitors the water pressure value P in the pipes in real time, and then the control component determines the scale condition.
[0083] S30, when the water pressure value P≤ the preset water pressure value P0, the three-way valve 132 is controlled to connect with the water tank 123, supplying clean water to the water tank 123, and the dispenser 122 is controlled to open, and the descaling agent in the descaling agent container 121 is discharged into the water tank 123 and mixed with the clean water to form a descaling agent solution.
[0084] Continue reading Figure 6As shown, the scale level in the pipeline is determined by comparing the water pressure value P with the preset water pressure value P0. When the water pressure value P is greater than the preset water pressure value P0, the descaling component 120 remains closed, and the cleaning component 110 continues cleaning. When the water pressure value P is less than or equal to the preset water pressure value P0, the control component determines that there is a large amount of scale accumulation and controls the three-way valve 132 to connect with the water tank 123, opening the dispenser 122 to deliver descaling agent into the water tank 123. The descaling agent mixes with clean water in the water tank 123 to form a descaling agent solution.
[0085] S40, control the descaling pump 124 to deliver descaling agent solution to the water cup 112, and the washing pump 111 continuously draws liquid from the water cup 112 to descaling and cleaning the water circuit with the descaling agent solution.
[0086] Specifically, the descaling pump 124 delivers the descaling agent solution in the water tank 123 to the water cup 112, and then the descaling agent is circulated in the pipeline by the washing pump 111, so that the scale is removed simultaneously under the conditions of the cleaning operation.
[0087] S50, when the water pressure value P > the preset water pressure value P0, the three-way valve 132 is controlled to disconnect from the water tank 123, the dispenser 122 is controlled to close, and the descaling pump 124 stops operating after pumping out the descaling agent solution in the water tank 123.
[0088] Specifically, as the descaling agent circulates, the scale in the pipeline is cleaned, and the water pressure value P returns to normal. When the water pressure value P > the preset water pressure value P0, the control component determines that the descaling operation is complete, the three-way valve 132 disconnects from the water tank 123, stops the water supply, and the dispenser 122 closes to stop the feeding. However, some descaling agent solution remains in the water tank 123. After the descaling agent continues to operate for a period of time, the water tank 123 is emptied and the operation is stopped to avoid bacterial growth caused by the liquid remaining inside the water tank 123.
[0089] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0090] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
