Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

First embodiment, generally contain in the running water and receive Cl, Ca, Mg plasma, because the existence of this type of ion, when the hardness of water exceeds 60ppm, easily at dish washer inner wall, electrical part surface scale deposit, along with the accumulation of time, the scale of condensing can be thicker and thicker, greatly reduced the life-span of electrical part to and reduce the abluent cleanliness of tableware, based on this, the utility model provides a water softening component and dish washer can solve above-mentioned problem, following embodiment will regard dish washer that includes water softening component as the example, explain the structural component and the principle of this water softening component and dish washer in detail, as shown in fig. 1-4, the dish washer of this embodiment includes:

a water inlet chamber 11 having a water inlet chamber inlet 110, a water inlet chamber outlet 111, and a water replenishing port 112, the water inlet chamber inlet 110 being connected to a water inlet source (e.g., a tap water pipe) through a water inlet pipe;

a water softening assembly comprising:

a soft water cavity 12 having a soft water cavity inlet, a soft water cavity outlet and a brine displacement port 122, wherein the soft water cavity 12 has a soft resin (not shown), the soft water cavity inlet is communicated with the water inlet cavity outlet 111, and the soft water cavity outlet is communicated with the inner container; the soft water in the soft water cavity enters the inner container through the soft water cavity outlet, so that the tableware in the inner container can be cleaned.

The brine chamber 13 is provided with a brine chamber inlet 131, a brine chamber outlet 132 and a salt adding port 133, the brine chamber inlet 131 is communicated with the water replenishing port 112, the brine chamber outlet 132 is communicated with the brine replacing port 122, a brine concentration detection alarm device 15 is arranged inside or outside the brine chamber 13, and the brine concentration detection alarm device 15 is connected with a controller (not shown in the figure), wherein the controller is a controller of the dishwasher.

The soft water cavity 13 can be filled with soft resin or other soft water substances capable of absorbing Cl, Ca, Mg and the like, and the brine cavity can be filled with regenerated salt which is mixed with water to form brine, wherein edible salt (mainly comprising NaCl) is preferred for the convenient purchase of the regenerated salt. Of course, the regenerating salt may be other substances capable of washing away Cl, Ca, Mg, etc. ions from the soft water, and is not limited herein.

When the inner bag of dish washer needs the water injection, the running water at first gets into intake antrum 11, then gets into soft water chamber 12 through soft water chamber entry from intake antrum 11, and soft water chamber 12 in the softened resin absorbs aquatic Cl, Ca, Mg plasma, and the softened water after the absorption flows into the inner bag of dish washer by soft water chamber export, and soft water intracavity softened resin's effect promptly lies in rejecting the Cl, Ca, Mg plasma in the running water.

When Cl, Ca, Mg and other ions adsorbed by the softened resin tend to be saturated, the adsorption effect of the softened resin is reduced, and the softened resin needs to be subjected to reduction regeneration.

The other path of tap water enters the saline water cavity 13 through the water replenishing port 112 of the water inlet cavity 11 and the saline water cavity inlet 131, and is mixed with the regenerated salt put in the saline water cavity 13 to form saline water, when the adsorption capacity of the softened resin is reduced, the tap water can be controlled to enter the soft water cavity 12 from the saline water cavity outlet 132 and the saline water replacement port 122, and is subjected to reduction treatment with the softened resin in the soft water cavity 12 to recover the softening capacity of the resin, and the reduced saline water is discharged to the inner container from the soft water cavity outlet.

The brine concentration in the brine chamber 13 decreases as the brine is discharged into the soft water chamber 12 to be consumed in reaction with the softened resin, and the replacement capability with the softened resin is lost, and therefore, a brine concentration detection alarm device 15 for detecting the brine concentration in the brine chamber 13 is provided on the brine chamber 13, and an alarm is given when the brine concentration is lower than a set value, and the brine concentration detection alarm device 15 is connected to a controller (not shown in the figure), which is a controller of the dishwasher.

As shown in fig. 1, the brine concentration detection alarm device of this embodiment includes concentration detection module 151, alarm module 152, and concentration detection module 151 is connected with the controller, and concentration detection module 151 can feed back the brine concentration signal that detects to the controller, and when the brine concentration is not enough, need report to the police to the user and indicate the salt that adds, and concentration detection module 151 can set up inside or outside at brine cavity 13 according to the detection principle difference.

The dish washer is also provided with other faults or prompts to alarm for a user, the alarm types are more, the user needs to investigate the alarm reason after hearing the alarm prompt, and the dish washer is very inconvenient to use. As shown in fig. 3, alarm module 152 includes alarm lamp 1521 and light guide column 1522 in this embodiment, and alarm lamp 1521 sets up the inboard in salt solution chamber 13 and is connected with the controller, and the light emitting area of alarm lamp 1521 is towards light guide column 1522, and light guide column 1522 extends to the surface from the internal surface of salt solution chamber 13. Through the mode that adopts leaded light post 1522 to derive light, alarm lamp 1521 can conceal the setting, need not set up the position that the user looked at the dishwasher shell surface easily, it is more nimble to set up the position, internal surface from salt solution chamber 13 through leaded light post 1522 extends to the surface, when the luminous suggestion of alarm lamp, the corresponding light of leaded light post is derived, the user sees from the outside that leaded light post department is luminous, the user judges easily that the reason of reporting to the police is because salt shortage causes in the salt solution chamber, reach the purpose of quick accurate to the user suggestion.

Salt water cavity 13 still has and adds salt mouth 133, when the salt water concentration is not enough, adds salt through adding the salt mouth to the salt water cavity, adds salt mouth 133 and is provided with the sealed lid 134 of detachable, and the user is pulled down this sealed lid 134 and is added salt through adding salt mouth 133 toward the salt water intracavity, plugs up sealed lid 134 when need not adding salt and adds salt mouth 133 to keep the inside cleanness in salt water cavity 13, prevent that dust, foreign matter from getting into.

The sealing cover 134 has a through hole, and the light guide column 1522 is disposed in the through hole. Through covering the leaded light post setting at sealed, and sealed lid can dismantle the setting and be adding salt mouth department, conveniently assembles leaded light post 1522, and sealed lid 134 belongs to the partly of salt water chamber 13, and the user judges equally very easily when seeing the leaded light post that is located sealed lid 134 and gives out light because the salt lacks in the salt water chamber and causes, reaches the purpose of quick accuracy to the user suggestion.

Salt adding mouth 133 sets up on the backplate of salt solution chamber 13, and alarm lamp 1521 preferably sets up on the preceding curb plate of salt solution chamber 13, and alarm lamp 1521's light-emitting direction is towards the back, also is alarm lamp 1521's light-emitting direction towards light guide column 1522.
