[0041] In order to make the technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] As mentioned above, in the current clothing washing process, there are technical problems that detergent and water cannot be fully mixed, the detergent dissolution process is slow, and the dissolution efficiency is low, which affects the clothing washing effect. To address this technical problem, the present application provides a circulating spray device for use in clothing processing equipment.

[0043] The clothes processing device may be a pulsator washing machine or a drum washing machine.

[0044] like Figure 1 As shown, the clothes processing device is a drum washing machine, which includes an inner drum and an outer drum, wherein the inner drum is located in the outer drum.

[0045] In one embodiment, the circulating spray device includes: a foaming component and a spray pipe 1. The inlet of the foaming component is connected to the outer drum or the inner drum through a connecting pipe, and the foaming component is used to foam the washing water in the outer drum or the inner drum. The outlet of the foaming component is used to return the foamed washing water to the inner drum or the outer drum. The foaming component is connected to the inner drum through the spray pipe 1, or the foaming component is connected to the inner drum through the spray pipe 1 and the spray head in sequence, and then the foamed washing water is sprayed onto the clothes in the inner drum. The present application fully mixes the detergent and water in the washing water in the outer drum through the foaming component, thereby improving the dissolution speed and dissolution efficiency of the detergent and improving the washing effect of the clothes. In the process of spraying the washing water to the clothes to be washed in the inner drum through the spray pipe 1, the mixing effect is further improved.

[0046] Specifically, the inlet of the foaming component is connected to the side wall of the outer tub. In one embodiment, the inlet of the foaming component is connected to the bottom of the outer tub so as to obtain enough washing water from the outer tub.

[0047] Preferably, in one embodiment, Figure 1 and Figure 2As shown, the foaming assembly includes a foamer 2, a connecting pipe 4 and a circulation pump 3. The inlet of the circulation pump 3 is connected to the outer drum through a connecting pipe, the outlet of the circulation pump 3 is connected to the inlet of the foamer 2 through a connecting pipe 4, and the outlet of the foamer 2 is connected to the inner drum through a spray pipe 1. The circulation pump 3 pumps the washing water in the outer drum into the inner drum after foaming by the foamer 2. The spray pipe 1 is arranged at the top of the inner drum to further enhance the foaming effect during the spraying process, and at the same time, increase the contact area between the washing water and the laundry during the spraying process to enhance the washing effect.

[0048] Preferably, in one embodiment, Figure 3 , Figure 4 and Figure 5 As shown, the foamer 2 includes a contraction section 21, a mixing chamber 22, a diffusion section 23 and an air intake section 24. The contraction section 21 and the diffusion section 23 are coaxially arranged. The thin end of the contraction section 21 and the thin end of the diffusion section 23 are connected to the mixing chamber 22 respectively, and the air intake section 24 is connected to the mixing chamber 22. The outlet of the circulation pump 3 is connected to the thick end of the contraction section 21 through the connecting pipe 4, and the thick end of the diffusion section 23 is connected to the spray pipe 1. Specifically, the air intake section 24 is connected to the external space or the inner cylinder space, and is used to input air into the mixing chamber 22. After the washing water enters the contraction section 21, the flow rate of the washing water flowing through the contraction section 21 increases due to the gradual decrease in the cross-sectional area. According to the Bernoulli principle, the increase in flow rate will cause the dynamic pressure of the fluid to increase and the static pressure to decrease, resulting in the formation of a negative pressure zone in the mixing chamber 22. The existence of the negative pressure zone allows air to enter the mixing chamber 22 through the air intake section 24. The inhaled air and washing water are fully mixed in the mixing chamber 22 to form bubbles. Then the fluid enters the diffusion section 23 , and as the cross-sectional area gradually increases, the flow rate slows down, the dynamic pressure of the fluid decreases, and the static pressure increases, the foamed washing water is sent into the spray pipe 1 .

[0049] Specifically, in one embodiment, the air intake section 24 is detachably mounted on the mixing chamber 22 , which is beneficial for cleaning and maintenance of the mixing chamber 22 .

The connecting pipe includes a first port, a second port and a third port, the first port is connected to the outer drum, the second port is connected to the inlet of the foaming component, and the third port is connected to the inlet of the sewage discharge component. That is, the washing water in the outer drum can enter the foaming component for foaming, and can also enter the sewage discharge component to be discharged outside the washing machine.

[0054] Specifically, in one embodiment, the connecting pipe connected to the outer cylinder connects the foaming component and the sewage discharge component through a tee 7 .

[0055] Preferably, in one embodiment, the circulating spray device further comprises a first filter element 8. The third port is located downstream of the second port, and the first filter element 8 is arranged at the second port so that the washing water flushes the first filter element 8 before flowing into the third port. Figure 6 As shown, the first filter element 8 is a mesh, which is arranged at the second port, and the third port is located downstream of the second port, so that when the sewage discharge component is started, the washing water flows through the first filter element 8 to clean the impurities and lint on the first filter element 8, so as to avoid the impurities and lint from accumulating and clogging the first filter element 8 and affecting the foaming effect.

[0056] Preferably, in one embodiment, Figure 1 and Figure 6 As shown, the sewage discharge assembly includes a sewage pump 5 and a second filter 9, and the second filter 9 is arranged between the third port and the inlet of the sewage pump 5.
