In one embodiment, please refer to Figures 6 and 7. The Venturi connector 33 includes an intubation tube 331 and an outer tube 332 located below the lotion box 31. The intubation tube 331 includes a water inlet section 3311 and a pressure reducing section 3312. The water inlet section 3311 The minimum flow cross-sectional area is greater than the flow cross-sectional area at any position of the decompression section 3312. The water inlet section 3311 is formed with a first interface 33a. The decompression section 3312 is connected to the first end of the outer tube 332 and extends into the outside. In the tube 332, the second end of the outer tube 332 is formed with a second interface 33b, and the peripheral side wall of the outer tube 332 is formed with a negative pressure port 33c. That is to say, the water inlet section 3311 is located outside the outer tube 332, and the pressure reducing section 3312 is located in the outer tube 332 and communicates with the space in the outer tube 332. The water flow from the first interface 33a flows through the decompression section 3312 and then flows to the second interface 33b. Since the minimum flow cross-sectional area of the water inlet section 3311 is larger than the flow cross-sectional area at any position of the decompression section 3312, the water flow The flow rate through the decompression section 3312 is greater than the flow rate of the water flow through the water inlet section 3311. The water pressure of the water flow in the decompression section 3312 is less than the water pressure of the water flow in the water inlet section 3311. The flow cross-sectional area of the outer pipe 332 is larger than that in the decompression section. 3312, the flow velocity of water in the decompression section 3312 is larger and the water pressure is smaller than that of the second interface 33b. The water pressure around the outlet of the decompression section 3312 is smaller, making the negative pressure port Negative pressure is generated at 33c to drive the liquid in the mixing chamber 31a to flow into the outer tube 332 through the negative pressure port 33c.

In one embodiment, please refer to Figure 7 . The water inlet section 3311 includes an equal diameter part 33111 and a gradual change part 33112. The flow cross-sectional area at any position of the equal diameter part 33111 is equal, and the gradual change part 33112 connects the equal diameter part 33111 and the pressure reduction part. In section 3312, the flow cross-sectional area of the gradient section 33112 gradually decreases from the equal diameter section 33111 toward the decompression section 3312. It can be understood that the flow cross-sectional area of the equal diameter portion 33111 and the flow cross-section area of the gradient portion 33112 are both larger than the flow cross-section area of the decompression section 3312. The water flow flows relatively smoothly in the equal diameter portion 33111, and the equal diameter portion 33111 plays a rectifying role so that the water flow smoothly enters the gradient portion 33112. The flow speed of the water flow gradually increases and the water pressure gradually decreases in the gradient portion 33112. The water pressure shows a continuous changing trend, which can reduce the turbulence of the water flow.

In one embodiment, please refer to FIG. 7 , the area of the flow cross section at any position of the decompression section 3312 is the same. In this way, the water flow flows relatively smoothly in the decompression section 3312, reducing turbulence and pressure loss.

In one embodiment, please refer to FIGS. 6 and 7 , both the intubation tube 331 and the outer tube 332 extend in the front-to-back direction. The detergent box 31 is located above the outer barrel 1, the door seal 2 is located at the front of the outer barrel 1, the water inlet valve is located at the rear of the outer barrel 1, the intubation tube 331 and the outer tube 332 both extend in the front and rear directions to facilitate the water supply flow path. 6 and drain channel 5 are routed.

In an exemplary embodiment, please refer to FIG. 7 , the cannula 331 and the outer tube 332 are coaxially arranged. In this way, the water flow in the intubation tube 331 and the outer tube 332 is smoother and the local resistance is smaller.

In one embodiment, please refer to FIG. 7 , the size of the decompression section 3312 along the axial direction of the outer tube 332 is larger than the size of the negative pressure port 33c along the axial direction of the outer tube 332 . That is to say, along the flow direction of the water flow in the outer tube 332, the negative pressure port 33c is upstream of the outlet of the decompression section 3312. This can effectively form negative pressure at the negative pressure port 33c.

In one embodiment, please refer to Figures 2 and 5. The detergent device 3 includes a spare connector 34 provided on the detergent box 31. The laundry treatment equipment includes an inlet channel 7 and a circulating water branch 8. The inlet channel 7 is connected to each other. The outlet and water inlet 32a of the circulating pump 4 and the circulating water branch 8 are connected to the water inlet channel 7 and the backup joint 34. When the filter 32 is clogged, the outlet back pressure of the inlet water channel 7 increases, forcing the circulating water to flow to the circulating water branch 8 and be discharged through the backup joint 34 . Therefore, the backup joint 34 and the circulating water branch 8 play a safety precaution role, and can promptly drain the circulating water into the water channel 7 when the filter 32 is clogged, thereby reducing the risk of pipe bursting and damage caused by a sharp increase in water pressure. The probability of circulation pump 4 and other failures.

The connecting pipe 35 connects the water inlet 32a and the water inlet channel 7. The spare joint 34 The highest part is higher than the highest part of the connecting pipe 35 . The resistance of the backup joint 34 is greater than the resistance of the connecting pipe 35. The resistance of the circulating water from the inlet channel 7 to the filter 32 through the connecting pipe 35 is less than the resistance of the flow to the backup joint 34. Therefore, when the filter 32 is used normally and is not blocked, In this case, the circulating water preferentially flows to the filter 32 through the connecting pipe 35 .

In one embodiment, please refer to FIG. 5 , the backup connector 34 is located on the top surface of the detergent box 31 . This ensures that the height of the backup joint 34 is relatively high.

In one embodiment, please refer to FIGS. 5 and 8 , the connecting pipe 35 is disposed on the circumferential wall of the lotion box 31 . For example, the backup joint 34 is formed on the box cover 311 , and the connecting tube 35 is penetrated on the rear side wall of the box body 312 . This ensures that the highest part of the connecting pipe 35 is lower than the height of the backup joint 34.
