Description

Technical Field

[0001] This utility model relates to the field of washer-extractor technology, and in particular to a double-bottom drainage structure for washer-extractors. Background Technology

[0002] In the current laundry industry, washing machines typically use either bottom-drain or rear-drain methods for drainage. When a washing machine is in operation, it usually consists of two parts: washing and rinsing / spinning. Normally, the single-drain method will drain all the water from the machine, while the water in the rinsing section is relatively clean and could have been used for subsequent machine operations. However, the drainage of the rinsing water also leads to a waste of some water resources.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a double bottom drainage structure for a washer-extractor, so as to realize the recycling of rinsing water, reduce water waste, and reduce water expenses.

[0005] The technical solution of this utility model is as follows: A double-bottom drainage structure for a washer-extractor is provided, comprising: an washer-extractor drum, and a double-bottom drainage structure; the double-bottom drainage structure includes: a water valve housing connected to the washer-extractor drum, a first driving device and a second driving device respectively installed on the water valve housing, a first drain outlet and a second drain outlet respectively connected to the water valve housing, a first valve connected to the first driving device, and a second valve connected to the second driving device; the first valve cooperates with the first drain outlet to block the first drain outlet, and the second valve cooperates with the second drain outlet to block the second drain outlet.

[0006] When the washer-extractor is in the washing or rinsing state, the first drive device controls the first valve at the first drain outlet, and the second drive device controls the second valve at the second drain outlet.

[0007] When the washing drum finishes washing and drains water, the first drive device moves the first valve out of the first drain outlet so that the wastewater can be discharged normally; the second drive device controls the second valve at the second drain outlet.

[0008] When the washing and drying drum has finished rinsing and is draining water, the second drive device moves the second valve out of the second drain outlet so that the rinsing water can be discharged normally into the water tank; the first drive device controls the first valve at the first drain outlet.

[0009] When washing is required, water from the sink is added to the washing drum for washing. Water is saved because the rinse water is reused for washing.

[0010] Furthermore, the washer-extractor with dual bottom drainage structure also includes a drainage box, through which the washer-extractor cylinder is connected to the water valve housing. The drainage box facilitates the connection between the washer-extractor cylinder and the water valve housing.

[0011] Furthermore, the washer-extractor with a dual-bottom drainage structure also includes a return water pipe connected to the drain box. The return water pipe facilitates the input of rinsing water from the pool into the washer-extractor drum.

[0012] Furthermore, the first driving device and the second driving device are arranged side by side.

[0013] Furthermore, the water valve housing is connected to the drain box via a flange.

[0014] Furthermore, the first driving device and the second driving device are pneumatic cylinders or electric cylinders.

[0015] By adopting the above solution, this utility model provides a double-bottom drainage structure for a washer-extractor. Wastewater after washing can be discharged from the machine through one of the drain outlets, while water after rinsing can be discharged into a water tank for storage through another drain cylinder. The water in the water tank can then be re-injected into the drum through a return pipe for subsequent washing, thereby achieving the effect of energy saving and emission reduction.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Please see Figures 1-4This embodiment provides a double-bottom drainage structure for a washer-extractor, including: an washer-extractor 10 and a double-bottom drainage structure 30; the double-bottom drainage structure 30 includes: a water valve housing 11 connected to the washer-extractor 10, a first drive device 12 and a second drive device 13 respectively installed on the water valve housing 11, a first drain outlet 14 and a second drain outlet 15 respectively connected to the water valve housing 11, a first valve 16 connected to the first drive device 12, and a second valve 17 connected to the second drive device 13; the first valve 16 cooperates with the first drain outlet 14 to block the first drain outlet 14, and the second valve 17 cooperates with the second drain outlet 15 to block the second drain outlet 15.

[0022] When the washing drum 10 is in the washing and rinsing state, the first drive device 12 controls the first valve 16 at the first drain outlet 14, and the second drive device 13 controls the second valve 17 at the second drain outlet 15.

[0023] When the washing drum 10 finishes washing and drains water, the first drive device 12 moves the first valve 16 out of the first drain outlet 14 so that the wastewater from washing can be discharged normally; the second drive device 13 controls the second valve 17 at the second drain outlet 15.
