It can be understood that, according to the detergent dispenser of the present invention, the specific structure of the valve portion 301 and the valve body 31 on the valve core 30 can be utilized to realize the communication between the water inlet channel 11 and the first water outlet 14 and the second water outlet 15 respectively, so as to communicate the water softener and the inner container of the dishwasher respectively.
In some embodiments, the control valve 3 further comprises an elastic member 33, and the elastic member 33 is used for driving the valve element 30 to reset. It is understood that the elastic member 33 may be a spring, for example, or may be other elastic materials.
Preferably, the elastic member 33 is disposed in the inner cavity 310, a first end of the elastic member 33 (a left end of the elastic member 33 shown in fig. 3) is connected to a second end of the valve body 30 (a right end of the valve body 30 shown in fig. 3), and a second end of the elastic member 33 (a right end of the elastic member 33 shown in fig. 3) is connected to the valve body 31. As shown in fig. 3, when the coil assembly 32 is powered on, the valve element 30 is driven to move rightwards, the valve element 30 compresses the elastic element 33 rightwards, the valve portion 301 is away from the third through hole 103 rightwards to conduct the water inlet channel 12 and the second water outlet 15, and the valve portion 301 blocks the first through hole 311 to disconnect the mounting hole 104 and the inner cavity 310 to disconnect the water inlet channel 12 and the first water outlet 14, so that the water in the water inlet channel 11 directly enters the inner container of the dishwasher through the second water outlet 15, that is, the second state; the coil assembly 32 is powered off and then driven to disappear, the valve core 30 moves leftwards and resets under the action of the reverse elasticity of the elastic element 33, the valve part 301 blocks the third through hole 103 leftwards to disconnect the water inlet channel 12 and the second water outlet 15, and the valve part 301 is far away from the first through hole 311 to conduct the mounting hole 104 and the inner cavity 310, so that water in the water inlet channel 12 can enter the first water outlet 14 through the mounting hole 104, the inner cavity 310 and the second through hole 312 in sequence, namely, the first state is realized, and therefore the water in the water inlet channel 12 enters the water softener through the first water outlet 14 firstly to be softened and then enters the inner container of the dishwasher.
In some embodiments, the body 1 further has a drainage chamber 17 therein, the drainage chamber 17 and the water inlet channel 12 are sequentially arranged in the left-right direction, the body 1 is further provided with a sewage inlet 16, a sewage outlet 18 and a communication hole (not shown), the sewage inlet 16, the drainage chamber 17 and the sewage outlet 18 are sequentially communicated, and the drainage chamber 17 is communicated with the atmosphere through the communication hole. Specifically, a communication hole is formed in the side wall enclosing the drain chamber 17, the communication hole is communicated with the breather chamber 101, and the breather chamber 101 is communicated with the vent hole 102 in the wall surface of the body 1, so that the drain chamber 17 is communicated with the outside atmosphere through the communication hole, the breather chamber 101 and the vent hole 102.
It can be understood that, when the dishwasher washes, the drainage cavity 17 communicates with the atmosphere through the communication hole, the water in the inner container of the dishwasher cannot enter the drainage cavity 17 through the sewage inlet 16, when the sewage in the inner container of the dishwasher needs to be discharged, the sewage in the inner container of the dishwasher is pumped into the drainage cavity 17 through the sewage inlet 16 under the action of the drainage pump (not shown), and is discharged through the sewage outlet 18 in the drainage cavity 17. The drain chamber 17 performs a drain function. Through arranging drainage chamber 17 and water inlet channel 12 in proper order about in the direction, can make the height of drainage chamber 17 compare in the water softener among the prior art highly high of drainage chamber, the liquid level in the inner bag of dish washer when than higher, can avoid the water in the inner bag to spill over and flow into in the drainage chamber 17 to the water softener of this embodiment can be more suitable for being applied to the high water groove machine of dish washer medium water level requirement.
In some embodiments, the respirator 100 further includes a float 4, the float 4 being provided in the drain chamber 17 for opening and closing the communication hole. Preferably, the float 4 has a tip 41, and the tip 41 may be adapted to be inserted into the communication hole to close the communication hole. Further, the float 4 includes a base 42 and a tip 41 provided at a tip of the base 42, the base 42 having a cylindrical shape and the tip 41 having a conical shape. It can be understood that the dishwasher does not discharge the wash water, and the communication hole is in an open state, i.e., the float 4 in the drain chamber 17 does not block the communication hole. When the dishwasher discharges sewage, a sewage inlet 16 of a sewage well in an inner container of the dishwasher enters the drainage cavity 17, the liquid level in the drainage cavity 17 is increased so that a buoy in the drainage cavity 17 moves upwards to block the communication hole, namely, the communication hole is in a closed state. In some embodiments, the timely closing of the communication hole by the float 4 can prevent the sewage from being discharged to the inner container of the dishwasher through the communication hole and the breather chamber 101.
In some embodiments, a baffle 5 is disposed in the drainage cavity 17, the drainage cavity 17 is divided into a sewage inlet cavity 171 and a sewage outlet cavity 172 by the baffle 5, the top of the sewage inlet cavity 171 is communicated with the top of the sewage outlet cavity 172, the sewage inlet cavity 171, the sewage outlet cavity 172 and the water inlet channel 12 are sequentially arranged along the left-right direction, the sewage inlet 16 is disposed at the bottom of the sewage inlet cavity 171, the communication hole is disposed at the top of the sewage inlet cavity 171, and the sewage outlet 18 is disposed at the bottom of the sewage outlet cavity 172.
In other words, as shown in fig. 2, the baffle 5 divides the drain chamber 17 into a sewage inlet chamber 171 and a sewage discharge chamber 172 which are sequentially arranged from left to right, and an upper end of the baffle 5 is spaced apart from a top wall surface of the drain chamber 17 to communicate the sewage inlet chamber 171 and the sewage discharge chamber 172 at a top of the drain chamber 17, the sewage inlet chamber 171 extends upward from below, and the sewage discharge chamber 172 extends downward from above, so that the drain chamber 17 is substantially in an inverted U shape. Advance sewage chamber 171, blowdown water chamber 172 and inhalant canal 12 and set gradually from a left side to the right side, inhalant canal 12 and advance sewage chamber 171, blowdown water chamber 172 and set up side by side promptly, then the height that the height of baffle 5 can set up is higher, for example highly high for the baffle in the respirator of now, improves the sewage memory space in the drainage chamber 17.
Preferably, the top of the sewage inlet chamber 171 and the top of the sewage discharge chamber 172 are in arc transition, that is, a section of the top of the drainage chamber 17 is an arc cavity. As shown in fig. 2, a section of the top of the drain chamber 17 is an arc-shaped chamber body bent upward.
The sewage inlet 16 and the sewage outlet 18 are sequentially arranged from left to right at the lower end of the body 1 and are spaced from each other, the sewage inlet 16 is at the lower end of the sewage inlet cavity 171 and is communicated with the sewage inlet cavity 171, the sewage outlet 18 is at the lower end of the sewage discharge cavity 172 and is communicated with the sewage discharge cavity 172, and the communication hole is at the upper end of the sewage inlet cavity 171 and is communicated with the sewage inlet cavity 171.
