Description

Technical Field

[0001] The present invention relates to the technical field of dishwashers, and in particular to a water softening component and a dishwasher. Background Art

[0002] As living standards improve, people's expectations for quality of life continue to rise, leading to a gradual increase in dishwasher awareness and acceptance. A water softener is a key component of a dishwasher. As the name suggests, it softens water. When water hardness exceeds 60 ppm, scale easily forms on the dishwasher's walls and electrical components. Over time, the accumulated scale thickens, significantly reducing the lifespan of the components. This reduces the dishwasher's performance and the cleanliness of dishwashing. Therefore, dishwashers require soft water. A water softener uses a resin to absorb calcium and magnesium ions from the water, then regenerates the resin with salt to soften the water.

[0003] In the prior art, a water softener needs to be installed independently in a dishwasher, which results in a complicated structure of the dishwasher and occupies a large installation space. In household dishwashers and small dishwashers with limited installation space, a water softener cannot even be installed.

[0004] In order to replenish the brine chamber with water, a current dishwasher needs to install a solenoid valve in the water replenishment channel. The brine chamber is replenished with water by controlling the on-off control of the solenoid valve. In addition, a detection device for detecting the water level in the brine chamber needs to be installed, which is costly.

[0005] In addition, the current salt water concentration detection and alarm device in the salt water chamber is relatively complex and cannot provide salt shortage alarm prompts. Summary of the Invention

[0006] In order to solve the technical problems that the existing water softening components used in dishwashers are not compact in structure, are not suitable for small household dishwashers, and cannot provide salt shortage alarms, the present invention proposes a water softening component and a dishwasher that can solve the above problems.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A water softening component, comprising:

[0009] A soft water chamber having a soft water chamber inlet, a soft water chamber outlet, and a brine replacement port, wherein the soft water chamber contains a softening resin, and the soft water chamber inlet is connected to a water source;

[0010] The brine chamber has a brine chamber inlet, a brine chamber outlet and a salt addition port. The brine chamber inlet is connected to the water replenishment port, and the brine chamber outlet is connected to the brine replacement port. A brine concentration detection alarm device is provided inside or outside the brine chamber, and the brine concentration detection alarm device is connected to the controller.

[0011] Furthermore, the salt adding port is provided with a detachable sealing cover.

[0012] Furthermore, an alarm light is provided on the saline chamber, the alarm light is connected to the controller, a through hole is provided on the sealing cover, the light guide column is provided in the through hole, and the light-emitting surface of the alarm light faces the light guide column.

[0013] Furthermore, the water replenishing port is connected to an overflow port, and the overflow port is located above the water replenishing port.

[0014] Furthermore, a liquid separation valve is provided between the soft water chamber inlet and the water inlet source, the inlet of the liquid separation valve is connected to the water inlet source, one outlet of the liquid separation valve is connected to the soft water chamber inlet, and the other outlet is connected to the hard water channel.

[0015] Furthermore, the opening position of the overflow port is not lower than the opening position of the brine chamber inlet.

[0016] Furthermore, the water replenishment port is connected to the brine chamber inlet through a water replenishment channel, the water replenishment channel is located below the brine chamber inlet, and a water baffle is provided in the brine chamber above the brine chamber inlet, and the water baffle is arranged obliquely.

[0017] Furthermore, a filter membrane is provided in the water replenishment channel.

[0018] Furthermore, a solenoid valve is provided between the brine chamber outlet and the brine replacement port.

[0019] The present invention also proposes a dishwasher, comprising an inner tank and a water inlet chamber, and also comprising a water softening assembly as described in any of the above items, wherein the water inlet chamber has a water inlet chamber inlet, a water inlet chamber outlet and a water replenishment port, the water inlet chamber inlet is connected to a water source through a water inlet pipe, the soft water chamber inlet is connected to the water inlet chamber outlet, and the soft water chamber outlet is connected to the inner tank.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are as follows: the water softening component of the present invention is provided with a soft water chamber and a brine chamber, and the soft water chamber contains a softening resin. The water from the water source enters the soft water chamber and is softened by the softening resin, which solves the technical problem that hard water directly enters the dishwasher and causes scaling in the inner cavity and residue on the surface of tableware for a long time. At the same time, by providing the brine chamber, the saturated softening resin can be regenerated. The structure of the water softening component is more compact and the volume is smaller, and it is particularly suitable for small-volume dishwashers such as household dishwashers.

[0021] Other features and advantages of the present invention will become more apparent after reading the detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: Generally, tap water contains Cl, Ca, Mg and other ions. Due to the presence of these ions, when the hardness of water exceeds 60ppm, scale is easily formed on the inner wall of the dishwasher and the surface of electrical components. As time accumulates, the condensed scale will become thicker and thicker, greatly reducing the life of the electrical components and the cleanliness of the dishwashing. Based on this, the present invention proposes a water softening component and a dishwasher that can solve the above problems. The following embodiment will take a dishwasher containing a water softening component as an example to explain in detail the structure, composition and principle of the water softening component and the dishwasher. Figure 1-Figure 4 As shown, the dishwasher of this embodiment includes:

[0029] The water inlet chamber 11 has a water inlet chamber inlet 110, a water inlet chamber outlet 111 and a water supply port 112. The water inlet chamber inlet 110 is connected to a water source (such as a tap water pipe) through a water inlet pipe;

[0030] A water softening component, comprising:

[0031] The soft water chamber 12 has a soft water chamber inlet, a soft water chamber outlet and a brine replacement port 122. The soft water chamber 12 contains softening resin (not shown in the figure). The soft water chamber inlet is connected to the water inlet chamber outlet 111, and the soft water chamber outlet is connected to the inner tank. The soft water in the soft water chamber enters the inner tank through the soft water chamber outlet to clean the tableware in the inner tank.

[0032] The brine chamber 13 has a brine chamber inlet 131, a brine chamber outlet 132 and a salt addition port 133. The brine chamber inlet 131 is connected to the water replenishment port 112, and the brine chamber outlet 132 is connected to the brine replacement port 122. A brine concentration detection alarm device 15 is provided inside or outside the brine chamber 13. The brine concentration detection alarm device 15 is connected to a controller (not shown in the figure), which is the controller of the dishwasher.

[0033] The soft water chamber 13 can be filled with softening resin or other water softening materials capable of absorbing Cl, Ca, Mg, and the like. The brine chamber can be filled with regeneration salt mixed with water to form brine. For ease of purchase, the regeneration salt is preferably edible salt (primarily containing NaCl). Of course, the regeneration salt can also be other substances capable of washing away Cl, Ca, Mg, and the like ions from the water softening material, and this is not a limitation.

[0034] When the inner tank of the dishwasher needs to be filled with water, tap water first enters the water inlet chamber 11, and then enters the soft water chamber 12 from the water inlet chamber 11 through the soft water chamber inlet. The softening resin in the soft water chamber 12 absorbs Cl, Ca, Mg and other ions in the water. The softened water after absorption flows into the inner tank of the dishwasher through the soft water chamber outlet. That is, the function of the softening resin in the soft water chamber is to remove Cl, Ca, Mg and other ions in the tap water.

[0035] When the Cl, Ca, Mg and other ions adsorbed by the softening resin tend to be saturated, the adsorption effect of the softening resin will decrease, and the softening resin needs to be reduced and regenerated.

[0036] The tap water enters the brine chamber 13 through the water replenishment port 112 of the water inlet chamber 11 and the brine chamber inlet 131, and mixes with the regenerated salt put into the brine chamber 13 to form brine. When the adsorption capacity of the softening resin decreases, the brine can be controlled to enter the soft water chamber 12 through the brine chamber outlet 132 and the brine replacement port 122, and perform a reduction treatment with the softening resin in the soft water chamber 12 to restore the softening capacity of the resin. The reduced brine is then discharged from the soft water chamber outlet to the inner tank.

[0037] As the brine is discharged into the soft water chamber 12 and consumed to react with the softening resin, the brine concentration in the brine chamber 13 decreases and will lose its ability to replace the softening resin. Therefore, a brine concentration detection and alarm device 15 is provided on the brine chamber 13 to detect the brine concentration in the brine chamber 13 and to issue an alarm when the brine concentration is lower than a set value. The brine concentration detection and alarm device 15 is connected to a controller (not shown in the figure), which is the controller of the dishwasher.

[0038] like Figure 1 As shown, the brine concentration detection and alarm device of this embodiment includes a concentration detection module 151 and an alarm module 152. The concentration detection module 151 is connected to the controller. The concentration detection module 151 can feed back the detected brine concentration signal to the controller. When the brine concentration is insufficient, an alarm needs to be issued to the user to remind him to add salt. The concentration detection module 151 can be set inside or outside the brine chamber 13 according to different detection principles.

[0039] There are many ways to alarm, such as light alarm, buzzer alarm, etc. Since the dishwasher may have other faults or prompts that need to be alerted to the user, there are many types of alarms. After hearing the alarm prompt, the user needs to check the cause of the alarm, which is very inconvenient to use. Figure 3 As shown, in this embodiment, the alarm module 152 includes an alarm light 1521 and a light guide 1522. The alarm light 1521 is arranged on the inner side of the salt water chamber 13 and is connected to the controller. The light-emitting surface of the alarm light 1521 faces the light guide 1522, and the light guide 1522 extends from the inner surface of the salt water chamber 13 to the outer surface. By using the light guide 1522 to guide the light, the alarm light 1521 can be set in a concealed position and does not need to be set in a position on the surface of the dishwasher shell that is easily visible to the user. The setting position is more flexible. The light guide 1522 extends from the inner surface of the salt water chamber 13 to the outer surface. When the alarm light is on, the light guide will guide the light accordingly. From the outside, the user sees that the light guide is emitting light. The user can easily determine that the alarm is caused by the lack of salt in the salt water chamber, thereby achieving the purpose of quickly and accurately prompting the user.

[0040] The brine chamber 13 also has a salt adding port 133. When the brine concentration is insufficient, salt is added to the brine chamber through the salt adding port. The salt adding port 133 is provided with a detachable sealing cover 134. The user removes the sealing cover 134 and adds salt to the brine chamber through the salt adding port 133. When salt is not needed, the sealing cover 134 is blocked with the salt adding port 133 to keep the interior of the brine chamber 13 clean and prevent dust and foreign matter from entering.

[0041] The sealing cover 134 has a through hole, and the light guide column 1522 is disposed within the through hole. By disposing the light guide column on the sealing cover, which is detachably disposed at the salt inlet, assembly of the light guide column 1522 is facilitated. Furthermore, the sealing cover 134 is part of the salt water chamber 13. When the user sees the light guide column on the sealing cover 134 glow, they can easily determine that the alarm is caused by a lack of salt in the salt water chamber, thereby providing a quick and accurate user alert.

[0042] The salt inlet 133 is located on the rear panel of the brine chamber 13, and the alarm light 1521 is preferably located on the front panel of the brine chamber 13. The light emitted by the alarm light 1521 is directed backward, that is, toward the light guide 1522. The light guide 1522 is located on the side of the inner tank. When the alarm is triggered, the user opens the dishwasher and the light emitted by the light guide 1522 is easily visible to the user.

[0043] The salt adding port 133 is preferably opened at the upper end of the back panel, and the alarm light 1521 corresponds to the salt adding port. Therefore, the alarm light 1521 is located at the upper end of the back panel to prevent the water flow from splashing water on the alarm light 1521 when water enters the salt water chamber 13, which is beneficial to extending the service life of the alarm light 1521.

[0044] Since brine is often stored in the brine chamber 13, the environment inside the chamber is high in salt and humidity. In order to prevent the alarm light from being corroded in this environment for a long time, a sealed chamber 135 is formed on the inner surface of the front side plate of the brine chamber 13. The alarm light 1521 is arranged in the sealed chamber 135 to isolate the alarm light from the high-salt and high-humidity environment in the brine chamber 13.

[0045] Conventional concentration detection module 151 utilizes the principle that the buoyancy of brine reflects its concentration. A float is positioned within the brine chamber 13, and the brine concentration is determined by detecting the float's position. However, this detection method, located within the chamber, is inconvenient during production and installation. In this embodiment, optical detection of brine concentration is preferred. This method utilizes the principle that brine concentration varies with its refractive index. Light is injected into the chamber and refracted by the solution within the chamber to determine the concentration. This optical detection device can be located outside the chamber, making it easy to assemble and resolving a number of issues associated with conventional detection devices located within the chamber. The concentration detection module 151 is connected to a controller and can provide feedback to the controller on the detected brine concentration signal.

[0046] like Figure 1As shown, the concentration detection module 151 of this embodiment includes a light source 1511 and a photosensor 1512, each connected to a controller. Photosensor 1512 is positioned in the optical path of light source 1511, which passes through the saline chamber 13. Light emitted by the light source propagates along its optical path, passing through the saline chamber and being refracted by the saline within the chamber before reaching the photosensor. Salt water of different concentrations has different refractive indices. Based on this principle, the photosensor can calculate the refractive index of the saline, and thus the concentration of the saline, by detecting the received light flux.

[0047] In this solution, the photoelectric principle is used to detect the concentration of salt water. Therefore, the detection device does not need to be in direct contact with the salt water and can be set outside the salt water chamber 13. A groove is formed on the outer surface of the front panel of the salt water chamber 13, and the light source 1511 is fixedly set in the groove. The photoelectric sensor 1512 is set on one of the side panels of the salt water chamber 13, and the photosensitive surface of the photoelectric sensor 1512 faces the light source 1511, ensuring that the photoelectric sensor 1512 is located in the light path of the light source 1511, and that the light path at least partially passes through the inner cavity of the salt water chamber.

[0048] In order to improve the prominence of the luminous alarm, it is preferred that there are two or more light guides 1522, and the sealing cover 134 is provided with through holes corresponding to the light guides 1522, and the light guides 1522 are arranged in the through holes corresponding thereto. The light guides 1522 can be sealed in the through holes by means of sealants, sealing rings, etc., with one end thereof reaching the inner cavity of the saline cavity 13 and the other end reaching the outer surface of the saline cavity. Therefore, the light emitted by the alarm light 1521 can be smoothly guided out to be observed by the user. By increasing the number of light guides 1522, its recognition can be improved and it can be more easily observed by the user. The present invention does not limit the number of light guides, and its number can be selected according to actual needs, or arranged according to a certain graphic pattern, all of which fall within the scope of protection of this patent.

[0049] In this embodiment, there is no need to set a solenoid valve between the salt water chamber inlet 131 and the water replenishment port 112, that is, there is no need to specifically control the water replenishment for the salt water chamber 13, the connecting port between the soft water chamber inlet and the water inlet source (corresponding to the water inlet chamber inlet 110) is open, and the water replenishment port 112 is arranged close to the connecting port between the soft water chamber inlet and the water inlet source. When the water inlet source injects water into the soft water chamber inlet through the connecting port, part of the water flow splashes to the water replenishment port 112, and enters the salt water chamber 13 from the water replenishment port 112 through the salt water chamber inlet 131. That is, as long as the water inlet source injects water into the soft water chamber 12, part of the water flow will enter the salt water chamber 13 for water replenishment, and there is no need to specifically control the water replenishment for the salt water chamber 13. A solenoid valve is set in the water channel to specifically control active water replenishment, which is beneficial to saving device costs. The passive water replenishment method adopted in this solution also brings another problem: the water inlet volume of the brine chamber 13 cannot be controlled. After the brine chamber 13 is filled, when the water source injects water into the inlet of the soft water chamber 12 through the connecting port, part of the splashed water flow needs to be discharged in time. Therefore, in this solution, the water replenishment port 112 is connected to the overflow port 113, and the overflow port 113 is located above the water replenishment port 112. By setting the overflow port 113 above the water replenishment port 112, it is ensured that the splashed water flow first enters the brine chamber 13 through the water replenishment port 112. When the brine chamber 13 is full, the water level rises and then is discharged through the overflow port 113.

[0050] The opening position of the overflow port 113 should not be lower than the opening position of the brine chamber inlet 131. According to the communicating vessel principle, the brine inside the brine chamber 13 is prevented from being discharged through the overflow port 113 or the brine chamber 13 cannot be filled.

[0051] The working process of the softening resin in the soft water chamber 12 is multiple cycles of adsorption-regeneration. Since the regeneration process cannot be completely thorough, the softening resin also has a service life. In order to extend the service life of the softening resin, a liquid separation valve is provided between the soft water chamber inlet and the water inlet source. Corresponding to the present embodiment, a liquid separation valve 18 is provided between the soft water chamber inlet and the water inlet chamber outlet 111. The inlet of the liquid separation valve 18 is connected to the water inlet chamber outlet 111, one of the outlets of the liquid separation valve 18 is connected to the soft water chamber inlet, and the other outlet is connected to the hard water channel 19, and the hard water channel 19 is connected to the inner tank. The liquid separation valve 18 can control the switching of the two pathways of water inlet source-inner tank and water inlet source-soft water chamber-inner tank. By controlling the conduction of the water inlet source-inner tank pathway when washing dishes, tap water is used to wash dishes. By controlling the conduction of the water inlet source-soft water chamber-inner tank pathway when rinsing, soft water is used for rinsing. This can not only solve the technical problems of hard water scaling and tableware residue, but also reduce the frequency of use of the softening resin and extend the service life of the softening resin.

[0052] The water replenishment port 112 is connected to the brine chamber inlet 131 through the water replenishment channel 20. The water replenishment channel 20 is located below the brine chamber inlet 131. It can be seen that the space can be fully and reasonably utilized, making the layout of each structure more compact, especially suitable for small dishwashers such as household dishwashers. A water baffle 136 is provided above the brine chamber inlet 131 in the brine chamber 13. The water baffle 136 is tilted and serves to stop water entering the brine chamber. Since the water replenishment channel 20 is located below the brine chamber inlet 131, the water inlet direction of the brine chamber 13 is upward. In order to prevent the incoming water from splashing toward the top of the brine chamber, the water baffle 136 stops the incoming water, so that the incoming water is stopped by the water baffle 136 and then flows back downward under the action of gravity, which can effectively alleviate the impact of the water pressure.

[0053] Since water is a liquid, it can flow freely to any connected place as the water pressure is unbalanced. In order to prevent the salt water in the salt water chamber 13 from entering the water inlet chamber 11 through the water replenishment channel 20 and then directly entering the inner tank through the overflow port 113, a filter membrane 21 is preferably provided in the water replenishment channel 20. The filter membrane 21 allows water molecules to pass through but prevents NaCl molecules from passing through, thereby avoiding the above-mentioned problem. Of course, this solution is not limited to the use of a filter membrane, and other filtering devices can also be used.

[0054] A solenoid valve 22 is provided between the brine chamber outlet 132 and the brine replacement port 122. Solenoid valve 22 is connected to a controller. When the softening resin's adsorption capacity decreases, solenoid valve 22 is controlled to open, connecting the soft water chamber 12 with the brine chamber 13. Brine enters the soft water chamber 12 and reacts with the softening resin to restore the resin's softening capacity. The reduced brine is then discharged from the soft water outlet. When reduction is no longer necessary, the solenoid valve closes, isolating the soft water chamber 12 from the brine chamber 13.

[0055] In order to prevent the softened water in the soft water chamber 12 from flowing back into the water inlet chamber 11 , a one-way valve 23 is preferably provided at the water inlet chamber outlet 111 .

[0056] To reduce the impact of water entering the inner container, a slow-flow chamber 24 is provided between the soft water chamber 12 and the inner container. The soft water chamber 12 communicates with the inlet of the slow-flow chamber 24 via the hard water channel 19, and the outlet of the slow-flow chamber 24 communicates with the inner container. When unsoftened water enters the inner container through the hard water channel 19, the slow-flow chamber 24 also serves to slow the flow.

[0057] In order to save the space occupied by the water channel, the hard water channel 19 starts from one side of the water inlet chamber 11 and the soft water chamber 12, extends upward along one side of the soft water chamber 12, and makes a 90° turn when it extends to the top of the soft water chamber 12, and extends to the other side of the soft water chamber 12. The slow flow chamber 24 is located on the other side of the water inlet chamber 11. When the hard water channel 19 extends to the top of the slow flow chamber 24, it makes a 90° downward turn. The entrance of the slow flow chamber 24 is located at the top of the slow flow chamber. The hard water channel 19 is connected to the entrance of the slow flow chamber 24. Therefore, the water inlet direction of the slow flow chamber is downward. When the water enters, it will be affected by the water pressure and the gravity of the water itself. In order to reduce the impact force of the water entering the slow flow chamber 24, and further reduce the impact force of the water entering the inner tank through the slow flow chamber 24, a slow flow baffle 16 is provided in the slow flow chamber 24. The slow flow baffle 16 is located below the entrance of the slow flow chamber and is tilted downward. The slow flow baffle 16 buffers the incoming water and then guides it downward, and finally enters the inner tank through the outlet.

[0058] In order to improve the capacity of collecting overflow water, the overflow port 113 is connected to the inner tank through the overflow channel 17. The overflow channel 17 extends downward from the overflow port 113. A connecting port connected to the inner tank is opened at the bottom of the overflow channel 17. When the brine chamber 13 is filled, the water level in the water inlet chamber 11 rises until it reaches the overflow port 113 and enters the overflow channel 17 through the overflow port 113. Since the overflow channel 17 extends downward from the overflow port 113, it has a certain capacity to accommodate overflow water, thereby reducing the impact of the overflow water on the inner tank when entering the inner tank.

[0059] In order to mitigate the impact of water entering the overflow channel through the overflow port 112 , a water retaining rib 171 is preferably formed on the inner wall of the overflow channel 17 .

[0060] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
