Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a descaling system, a dishwasher and a descaling method. Background Art

[0002] Scale is very harmful to dishwashers. It is easy to adhere to the heating plate, washing pump and water pipe surface. The accumulation of scale may make the dishwasher unable to work properly, and in severe cases, it may cause damage to the dishwasher. In the related technology, the dishwasher is generally equipped with a water softener, which can soften the tap water entering the dishwasher to prevent scale from being generated by long-term washing of dishes with hard water. The water softener mainly uses resin to replace the calcium ions and magnesium ions in the hard water, and form them into water-soluble compounds. However, after the resin has worked for a period of time, the sodium ions on its surface will be exhausted, and special salt needs to be added in time, but many users forget to add it, resulting in scale accumulation. Summary of the invention

[0003] Based on this, it is necessary to provide a descaling system, a dishwasher and a descaling method to address the problem of scale accumulation caused by users not adding salt for a long time.

[0004] To achieve the above objectives, the technical solutions adopted in this application are as follows:

[0049] In addition, if the term "and / or" appears, "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0050] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0053] In the related art, although the water softener of the dishwasher can soften hard water, it often needs to add salt as a consumable to replace the resin to maintain the water softening ability. Salt, as a consumable, does not play a decisive role in the effect of dishwashing. Although the machine is equipped with a salt shortage indicator light reminder, since the lack of salt will not affect the operation of the machine, even if there is a lack of salt, the user may not necessarily add salt during use, which will cause scale accumulation and damage to the dishwasher.

[0054] See also Figure 1 As shown, in order to improve the above problems, the embodiment of the present application provides a descaling system 100 for cleaning scale in the waterway, specifically for the cleaning waterway of the dishwasher. The descaling system 100 can automatically add descaling agent to perform descaling and cleaning of the waterway without the need for manual addition of salt, thereby improving the user experience and extending the service life of the dishwasher.

[0055] It should be noted that the descaling system 100 provided in the present application is not limited to the application in dishwashers, but can also be applied to water-using equipment such as water heaters, humidifiers, and water purifiers. For ease of understanding, a dishwasher is used as an application scenario of the descaling system 100 in the embodiments of the present application for illustration.

[0056] Specifically, the descaling system 100 includes a cleaning component 110, a detection component and a descaling component 120. The cleaning component 110 is used to deliver cleaning liquid to the inside of the dishwasher to clean the dishes. The detection component is arranged in the water path of the cleaning component 110 to monitor the water pressure value P in the water path in real time, and then judge the scale accumulation in the water path. The descaling component 120 is electrically connected to the detection component, so that when scale exists in the water path, the descaling agent solution is automatically delivered to the cleaning component 110.

[0057] It should be noted that the principle for judging the scale accumulation in the embodiment of the present application is: as the scale increases, the water pressure value P in the water circuit decreases, thereby passing through the preset water pressure value P0 under the normal state. When the water pressure value P≤the preset water pressure value 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, the dishwasher includes an inner tank 200 for washing dishes, and a bowl basket 300 is arranged inside, and the dishes are placed on the bowl basket 300. The cleaning component 110 includes a washing pump 111, and the washing pump 111 sprays the cleaning liquid into the inner tank 200 to clean the dishes placed on the bowl basket 300.

[0059] In some embodiments, the cleaning component 110 further includes a water cup 112 and a drainage pump 113 , and the water cup 112 is connected to the washing pump 111 , the drainage pump 113 , and the descaling component 120 , respectively.

[0060] Specifically, the water cup 112 stores cleaning liquid, one side of which is connected to the input end pipeline of the washing pump 111, and the output end of the washing pump 111 is connected to the inner tank 200, so that the cleaning liquid in the water cup 112 is output to the tableware in the bowl basket 300 for cleaning. The drainage pump 113 is connected to the bottom side of the water cup 112, so that after the cleaning is completed, the liquid in the water cup 112 can be completely discharged to avoid the residual water in the water cup 112 causing bacteria to grow or corrosion damage to the container. In addition, the water cup 112 is also connected to the descaling component 120, so that when descaling is required, the water cup 112 receives the descaling agent solution from the descaling component 120, and through the extraction of the washing pump 111, the descaling agent flows through the cleaning waterway to dissolve the scale in the waterway, thereby ensuring 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, during the descaling process, the water cup 112 can effectively store the descaling agent solution from the descaling component 120, and as the washing pump 111 continues to draw, it can effectively clean the scale in the water channel while meeting the cleaning operation.

[0061] Furthermore, the cleaning assembly 110 further includes a spray arm, which is connected to the output end of the washing pump 111. Exemplarily, the spray arm is installed below the bowl basket 300, and a plurality of spray ports are provided on a side thereof close to the bowl basket 300. Thus, under the condition that the spray arm is connected to the output end of the washing pump 111, the washing pump 111 continuously outputs the cleaning liquid to the spray arm, and forms a spray through the spray arm, so that the spray is directly sprayed on the tableware in the bowl basket 300, thereby improving the cleaning effect.

[0062] Preferably, the water cup 112 is disposed at the bottom of the inner tank 200, and the top is connected to the inner tank 200, so as to receive the cleaning liquid sprayed by the spray arm in the inner tank 200, so as to realize the recycling of the cleaning liquid and improve resource utilization. Furthermore, the washing pump 111 is connected to the bottom of the water cup 112, so as to ensure the water supply pressure of the washing pump 111 and reduce the influence of the scum on the washing pump 111 during the washing process.

[0063] In some embodiments, the water cup 112 is integrated with the inner liner 200 to simplify the overall structure. Of course, in other embodiments, the water cup 112 can also be disassembled and assembled with the inner liner 200 to facilitate the maintenance of each component.

[0064] In the embodiment of the present application, the detection element may be a pressure sensor and is used to feedback the water pressure of the waterway. The detection element is installed on the end side of the washing pump 111 and monitors the water pressure value P on 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 ​​of the output end and the input end. In this way, the specific value of the preset water pressure value P0 can be adjusted accordingly, so as to evaluate the scale condition of the waterway system.

[0065] Continue reading Figure 3 As shown, in some embodiments, the descaling component 120 includes a descaling agent container 121, a dispenser 122, and a water tank 123. The descaling agent container 121 contains a descaling agent and is provided with a discharge port 1211, the dispenser 122 is disposed at the discharge port 1211 and is used to control the discharge of the descaling agent, and the water tank 123 is respectively connected to the discharge port 1211 and the cleaning component 110, and the descaling agent is dissolved in the water tank 123 to form a descaling agent solution.

[0066] Exemplarily, the descaling agent may be composed of citric acid. Citric acid (C6H8O7) reacts with scale to generate CaC6H5O7 and MgC6H5O7, which are easily soluble in water. The CaC6H5O7 and MgC6H5O7 are retained in the water cup 112 during the washing process and are discharged from the dishwasher through the drain pump 113 after the washing is completed. 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 demand to realize automatic feeding of the descaling agent. After the descaling agent falls into the water tank 123, it is mixed and dissolved with the water in the water tank 123 to form a solution, and is output to the water cup 112 through the pipeline.

[0067] Furthermore, the descaling assembly 120 further 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 can continuously deliver 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 component 120 further includes a float, which 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 obtain a water level signal of the liquid surface. When the descaling operation is stopped, since there is still solution in the water tank 123, the descaling pump 124 needs to continue to extract the descaling solution in the water tank 123. In this way, the height of the liquid level in the water tank 123 can be obtained by 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 emptying.

[0070] In some embodiments, the descaling system 100 further includes a water supply assembly 130, which is respectively connected to the cleaning assembly 110 and the descaling assembly 120. Exemplarily, the water supply assembly 130 can be connected to the water tank 123 and the water cup 112 at the same time, so that only one water source is needed to simultaneously deliver liquid to the water tank 123 and the water cup 112.

[0071] Continue reading Figure 4 As shown, further, the water supply component 130 includes a water inlet valve 131 and a three-way valve 132, and the three ports of the three-way valve 132 are respectively connected to the water inlet valve 131, the cleaning component 110, and the descaling component 120.

[0072] Specifically, the water inlet valve 131 is connected to a port pipeline of the three-way valve 132, and automatically controls the supply of water 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 the cleaning operation is required, the end of the three-way valve 132 connected to the water tank 123 is closed, and only liquid is delivered to the water cup 112 to ensure the cleaning of the tableware. When the descaling operation is required, the three-way valve 132 is connected to the water tank 123 and the water cup 112 at the same time. While meeting the cleaning operation, part of the liquid enters the water tank 123 and mixes with the descaling agent to form a solution, and is output to the water cup 112 through the descaling pump 124.

[0073] Furthermore, the water supply assembly 130 further includes a flow meter 133, which is disposed between the water inlet valve 131 and the three-way valve 132. By disposing the flow meter 133, the supply rate of the water source can be reasonably controlled, and the control accuracy of the system can be improved.

[0074] It is understandable that the descaling system 100 provided in the present application also includes a control component to automatically operate the system. Exemplarily, the control component can be a central processing chip, which is electrically connected to each electrical component to send operation instructions to each component. The control component obtains the water pressure value P of the detection component through an internal setting program, and then judges the scale condition in the water circuit, and then controls the start and stop of each valve and the descaling pump 124.

[0075] An embodiment of the present application further provides a dishwasher, comprising the descaling system 100 in any of the above embodiments.

[0076] This embodiment has the descaling system 100 in any of the above embodiments, and therefore has all the beneficial effects of the descaling system 100 in any of the above embodiments, which will not be described in detail here.

[0077] See also Figure 5 As shown, an embodiment of the present application further provides 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, controlling the water inlet valve 131 to open, and supplying clean water to the water cup 112 through the three-way valve 132.

[0080] Specifically, during the washing operation of the dishwasher, 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 a set height, the water inlet valve 131 can be closed to stop the clean water supply.

[0081] S20, controlling the washing pump 111 to continuously spray the clean water in the water cup 112 onto the object to be washed, and the detection component monitors the water pressure value P at the end side of the washing pump 111 in real time.

[0082] Specifically, the washing pump 111 sprays the clean water in the water cup 112 onto the bowl basket 300 through the spray arm to clean the tableware. As the water flows during the washing process, scale is easily deposited in the pipeline, thereby affecting the water flow pressure. The monitoring component monitors the water pressure value P in the pipeline in real time, and then determines the scale situation through the control component.

[0083] S30, when the water pressure value P≤preset water pressure value P0, the three-way valve 132 is controlled to be connected with the water tank 123, clean water is supplied to the water tank 123, 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 clean water to form a descaling agent solution.

[0084] Continue reading Figure 6As shown, the scale condition in the pipeline is determined based on the comparison between the water pressure value P and 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≤the preset water pressure value P0, the control component determines that the current scale accumulation is large, controls the three-way valve 132 to communicate with the water tank 123, and the dispenser 122 is opened to transport the descaling agent into the water tank 123. The descaling agent is mixed with clean water in the water tank 123 to form a descaling agent solution.

[0085] S40, controlling the descaling pump 124 to deliver the descaling solution to the water cup 112, and the washing pump 111 continuously extracts the liquid in the water cup 112, so that the descaling solution performs descaling and cleaning of the water channel.

[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 circulates in the pipeline through the delivery of the washing pump 111, and the scale is removed simultaneously when the cleaning operation conditions are met.

[0087] S50, when the water pressure value P> the preset water pressure value P0, the three-way valve 132 is controlled to be disconnected from the water tank 123, the dispenser 122 is controlled to be closed, 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 completed, the three-way valve 132 is disconnected from the water tank 123, the water supply is stopped, and the dispenser 122 is closed to stop feeding. However, some descaling agent solution still 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 the liquid inside the water tank 123 causing bacteria to grow.

[0089] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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 above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
