The first embodiment is as follows:

a dishwasher, as shown in fig. 1 to 5, comprises a water softener 300, wherein the water softener 300 comprises an upper cover 310 provided with a water inlet 311 and a lower shell 320 provided with a water outlet 321, the upper cover 310 covers the lower shell 320 to form a containing cavity 330, a scale inhibitor 350 is arranged in the containing cavity 330, hard water (tap water containing metal ions such as calcium and magnesium) entering the dishwasher enters the containing cavity 330 through the water inlet 311, the scale inhibitor 350 in the containing cavity 330 performs scale inhibition on water flow passing through the containing cavity 330, so that the water flowing to the inner cavity of the dishwasher through the water outlet 321 is soft water (tap water containing no metal ions such as calcium and magnesium), namely, the water entering the dishwasher is softened, so that the water entering the inner cavity of the dishwasher and used for washing dishes is soft water, and the metal ions in the water flow are prevented from forming scale in the inner cavity of the dishwasher.

The utility model discloses a set up water softener 300 in the water route that lets in the dish washer inner chamber, and set up in water softener 300 and can get rid of metal ion's antisludging agent 350, make the hard water that gets into the dish washer get into through inlet opening 311 and hold in the chamber 330, hold antisludging agent 350 in the chamber 330 and hinder the dirt to the rivers that hold in the chamber 330, so that the water that flows to the dish washer inner chamber through apopore 321 is the soft water, the softening that gets rid of metal ion promptly to the water that gets into the dish washer, prevent that the metal ion in the rivers from forming the incrustation scale in the dish washer inner chamber, only realize the effect of soft water through simple structure, when the volume is less and occupation space is less, manufacturing process is simple, reduce the production and manufacturing cost.

The scale inhibitor 350 in this embodiment is preferably a FOF metaphosphate, and when water flows through the FOF metaphosphate, the FOF metaphosphate polymerizes with metal ions in the water to form a polymer, so as to remove the metal ions. Because the FOF metaphosphate scale inhibitor of 5g in the accommodating cavity 330 can handle about 4000L of water with 250ppm hardness, if the dishwasher calculates according to 5L of single water consumption, the 4000L water can be used for about 800 times by the dishwasher, even if the dishwasher is used for 3 times in 1 day, the module is only required to be replaced once in 267 days, which is 7 times of the service cycle of the scheme of adding 500g salt in the prior art, the volume of the water softener 300 is greatly reduced, and the frequent replacement of the water softener 300 by a user is not needed, thereby improving the use experience of the user.

Because the scale inhibitor 350 is granular, in order to prevent the particles of the scale inhibitor 350 from coming out of the accommodating cavity 330 without arranging other shielding structures, the width of the water inlet hole 311 and the width of the water outlet hole 321 are set to be smaller than the diameter of the particles of the scale inhibitor 350, so that the scale inhibitor 350 in the accommodating cavity 330 is directly limited, the structure is simple, and the production and installation are easy.

As shown in fig. 3 and 5, the accommodating chamber 330 in this embodiment is further provided with a filter element 340, the filter element 340 divides the accommodating chamber 330 into an upper chamber 331 and a lower chamber 332 located at the lower part of the upper chamber 331, the upper chamber 331 is communicated with the water inlet 311, the lower chamber 332 is communicated with the water outlet 321, and the scale inhibitor 350 is disposed in the lower chamber 332, so that hard water entering the upper chamber 331 through the water inlet 311 is firstly filtered under the action of the filter element 340, impurities such as particles in the hard water are isolated in the upper chamber, the water flowing through the scale inhibitor 350 is cleaner, the impurities such as particles are prevented from staying in the scale inhibitor 350 to affect the soft water effect of the scale inhibitor 350, and the soft water module not only has a soft water effect, but also has a filtering effect. Filter core 340 in this implementation can be the filter core 340 of various materials, and is preferred, adopts cotton filter core 340 of PP or active carbon filter core 340, and is better to the filter effect of rivers, for the filter effect of reinforcing filter core 340 to rivers, also can adopt the filter core 340 that has antibacterial material.

In this embodiment, as shown in fig. 4, an annular clamping rib 312 is disposed on an outer peripheral side of the upper cover 310, an annular clamping groove 322 is disposed on an inner side wall of the lower housing 320, and the annular clamping rib 312 is clamped with the annular clamping groove 322 to lock the upper cover 310 on the lower housing 320, so as to prevent the upper cover 310 from moving axially on the lower housing 320, and ensure a sealing effect of the upper cover 310 and the lower housing 320 on the accommodating cavity 330.

In this embodiment, the dishwasher further includes a water tank 100, a spray arm disposed in the inner cavity of the dishwasher, and a water pipe 600 connected between the water outlet 110 at the bottom of the water tank 100 and the spray arm, the water tank 100 and the water pipe 600 are communicated through a water connector 400, the water connector 400 is located at the bottom of the water tank 100 for communicating the water outlet 110 at the bottom of the water tank 100 with the water inlet end of the water pipe 600, and the water softener 300 is installed in the water connector 400, such that hard water in the water tank 100 flows out through the water outlet 110 at the bottom of the water tank 100, and then softens and becomes soft water when passing through the water softener 300 in the water connector 400, and then enters the spray arm through the water pipe 600 to spray and clean the dishes in the inner cavity of the dishwasher. The water softener 300 is installed and positioned by arranging the water connector 400 between the water tank 100 and the water passing pipe 600, so that the water softener 300 with a small volume is directly arranged at the water inlet end of the water passing pipe 600, and the occupied space is small.

In this embodiment, the handle 313 protruding from the top surface of the upper cover 310 is further disposed on the upper cover 310, after the water tank 100 is detached by a user, the water softener 300 disposed in the water circuit connector 400 can be taken out through the handle 313 for replacement without using tools, which is convenient for the user to operate, and the anti-slip protrusion 3131 is disposed on the handle 313 to prevent the user from slipping between the hand and the handle 313 when the user holds the handle 313, so that the operation is more stable.
