According to the above connection relationship, the following description is made on the mounting positions of the components:

as shown in fig. 1, the device comprises an outer cylinder 2 coaxially sleeved outside the inner cylinder 1, wherein the liquid level detection element 711, the temperature measurement element 712, the wireless signal transmitting end 721 and the wireless charging receiving end 731 are arranged on the inner cylinder 1 at intervals or integrally, and the wireless charging transmitting end 732 is arranged on the outer cylinder 2 and corresponds to the position of the wireless charging receiving end 731. When the wireless signal transmitting ends 721 and the wireless charging receiving ends 731 are arranged at intervals, the wireless signal transmitting ends 721 and the wireless charging receiving ends 731 are configured according to the number of specific situations, and when the wireless signal transmitting ends 721 and the wireless charging receiving ends 731 are arranged in an integrated mode, the two wireless signal transmitting ends 721 and the two wireless charging receiving ends 731 are preferably arranged and are respectively arranged in an integrated mode with the liquid level detection element 711 and the temperature measurement element 712, and therefore the assembly efficiency of the washing machine is improved.

When the washing machine executes the water inlet program, the control device controls the heating device 5 in the washing machine to heat the inner barrel, the control device is provided with a washing temperature, the control device receives a feedback temperature signal of the temperature measuring element 712 in real time, and when the feedback temperature signal is more than or equal to the washing temperature, the control device 5 stops heating the inner barrel 1.

In another embodiment, the heating time t of the heating device 5 is:

t＝C·m·(T₁-T₀)/(P·η)；

wherein: c is the specific heat capacity of water;

T₀the initial temperature of the inlet water detected by the temperature measuring element 71;

T₁setting the washing temperature in the control device;

In this embodiment, the mounting sleeve 46 is a vertically extending cylindrical structure, the lower end of the mounting sleeve 46 is open, the upper end of the mounting sleeve is provided with a folding edge 427 protruding horizontally inward, and the inner periphery of the folding edge 427 is provided with an inner peripheral folding edge 428 extending vertically downward to the lower end of the mounting sleeve; the outer wall of the inner peripheral flange 428 is spaced from the inner wall of the flange 427 by a gap to form a chamber for mounting and fixing the return spring 432 of the sealing valve; preferably, the return spring 432 is sleeved on the outer wall of the inner peripheral folded edge 428, the upper end of the return spring 432 is abutted against the lower side of the folded edge 427, and the lower end of the return spring 432 is abutted against the big end of the valve core 424; it is further preferred that the outer wall of the plug post 45 abut against a corresponding stop on the inner wall of the inner peripheral flange 428.

In this embodiment, one side of the mounting sleeve 46 is provided with a second extending rib 414 protruding and extending outward horizontally, an extending end of the second extending rib 414 is provided with a hinge hole 431 whose axis is horizontally arranged, and the counterweight 47 of the sealing valve and the second extending rib 17 are hinged and mounted through a bolt passing through the hinge hole 431.

In this embodiment, the upper end of the counterweight block 47 is provided with a connecting rib 8 which protrudes and extends upward along the axial direction, the upper end of the valve plug column 45 penetrates through the top of the mounting sleeve 46, and the end part of the connecting rib 8 is hinged with the upper end of the valve plug column 45; the middle part of the connecting rib 8 is correspondingly overlapped and spliced with the second extending rib 414 of the mounting sleeve 46, and the overlapped part is hinged and mounted through a penetrating bolt; preferably, the extending end of the second extending rib 414 is higher than the top of the mounting sleeve 46, the extending end of the second extending rib 414 is provided with an insertion groove 413, the insertion groove 413 is arranged along the extending direction of the second extending rib 414, and the middle part of the connecting rib 8 of the sealing valve is correspondingly inserted into the insertion groove 413; the slot 413 is provided with a hinge hole 431 extending horizontally, and the middle part of the connecting rib 8 is provided with a hinge hole which is correspondingly overlapped so as to be hinged and installed at the overlapped part through a penetrating bolt.

In this embodiment, the end of the connecting rib 8 is provided with a rotating hole hinged to the upper end of the valve plug 45, and the rotating hole is a long-strip-shaped through hole 33 extending along the axial direction of the connecting rib shaft 8, so as to provide a space margin for the connecting rib 8 to drive the valve plug 45 to move up and down when the balancing weight 47 rotates around the mounting sleeve 46.

In this embodiment, the outer diameter of the upper end of the valve core 424 is larger than the lower diameter of the inner peripheral flange, and the height of the valve core 424 is smaller than the height of the gap between the support plate and the inner barrel side wall.

In this embodiment, two sealing valves that are arranged oppositely are disposed in the installation cavity 43 enclosed inside the lifting rib 4, the two sealing valves are arranged along the inner cylinder construction line direction, and the counter weights 47 of the valve core structures of the two sealing valves are opposite and extend in the approaching direction.

In this embodiment, when the washing machine is in a dewatering and/or draining state, the inner cylinder is in a high-speed rotation state, water in the inner cylinder flows to be attached to the inner wall under the action of centrifugal force, flows into the lifting rib from a gap between the inner cylinder wall and the lifting rib, and moves to the outer periphery of the inner cylinder under the action of the centrifugal force, and the balancing weight provides upward prying force towards the center direction of the inner cylinder for the valve plug column through the connecting rib; when washing machine is in non-dehydration, non-drainage state, the inner tube is not in high-speed rotation state, and the balancing weight no longer receives centrifugal force effect, and reset spring is in and draws the state of drawing, and reset spring makes the valve core move to initial position until closed outlet to inner tube is in washing or rinsing procedure earlier on to the valve plug post effect, and reset spring provides an elasticity to the valve plug post all the time to guarantee that the valve core blocks up the outlet all the time, and then guarantee that the outlet is in closed state all the time.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
