A drainage mechanism and a washing and drying machine

Abstract

The present invention discloses a drainage mechanism and a washing and drying machine thereof. The drainage mechanism includes a flow regulating component, a water pipe and a pressure transmission pipe. The pumping component is connected to the water pipe. The flow regulating component is arranged on the water pipe and has a valve core unit that can extend into the water pipe. The present invention connects one end of the pressure transmission pipe to the water pipe located on a side of the flow regulating component away from the pumping component, connects the other end of the pressure transmission pipe to the flow regulating component, and connects the end of the water pipe away from the pumping component to a sewer. When the sewer is blocked or the sewer pipe diameter is small, the pressure on the side of the water pipe located on the flow regulating component away from the pumping component becomes greater, and the pressure transmission pipe transmits the water pressure to the flow regulating component. The pressure can cause the flow regulating component to drive the valve core unit to adjust the opening of the water pipe to become smaller, thereby preventing the washing and drying machine from draining too quickly and the water from being discharged untimely, resulting in water overflow.

[0017] An embodiment of the present invention discloses a drainage mechanism for a washer-dryer. The washer-dryer includes a barrel assembly and a pumping assembly, the pumping assembly being disposed within the barrel assembly. The drainage mechanism includes a flow regulating assembly, a water pipe, and a pressure transmission pipe. The pumping assembly is connected to the water pipe.

[0036] Example 1

[0037] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a drainage mechanism for a washing and drying machine, the washing and drying machine comprising a barrel assembly and a pumping assembly 1, the pumping assembly 1 being arranged in the barrel assembly, the drainage mechanism comprising a flow regulating assembly 2, a water pipe 3 and a pressure transmission pipe 4, the pumping assembly 1 being connected to the water pipe 3, the flow regulating assembly 2 being arranged on the water pipe 3, and having a valve core unit 21 capable of extending into the water pipe 3, one end of the pressure transmission pipe 4 being connected to the water pipe 3 on a side of the flow regulating assembly 2 away from the pumping assembly 1, and the other end being connected to the flow regulating assembly 2, so that the flow regulating assembly 2 drives the valve core unit 21 to adjust the opening of the water pipe 3 according to the pressure difference on both sides thereof.

[0038] In this embodiment, the drainage mechanism is used for a washing and drying machine, which includes a barrel assembly and a pumping assembly 1. The pumping assembly 1 is arranged in the barrel assembly. The drainage mechanism includes a flow regulating assembly 2, a water pipe 3 and a pressure transmission pipe 4. The pumping assembly 1 is connected to the water pipe 3. The flow regulating assembly 2 is arranged on the water pipe 3 and has a valve core unit 21 that can extend into the water pipe 3. In this embodiment, one end of the pressure transmission pipe 4 is connected to the water pipe 3 on the side of the flow regulating assembly 2 away from the pumping assembly 1, and the other end of the pressure transmission pipe 4 is connected to the flow regulating assembly 3. The flow regulating component 2 is connected to the drain pipe 3, and the end of the water pipe 3 away from the pumping component 1 is connected to the sewer. When the sewer is blocked or the sewer pipe diameter is small, the pressure on the side of the water pipe 3 located at the flow regulating component 2 away from the pumping component 1 becomes larger, and the pressure transmission pipe 4 transmits the water pressure to the flow regulating component 2. This pressure can make the flow regulating component 2 drive the valve core unit 21 to adjust the opening of the water pipe 3 to become smaller. Therefore, the drainage mechanism of this embodiment solves the problem of water discharged from the washing and drying machine overflowing when the sewer is blocked or the sewer pipe diameter is small, and avoids water overflow caused by the washing and drying machine draining too quickly and not being discharged in time.

[0039] In some embodiments, the washer-dryer further includes a drain pipe 6 ; the drain pipe 6 is connected between the water pipe 3 and the pumping assembly 1 .

[0040] In this embodiment, the drainage pipe 6 is connected between the water pipe 3 and the pumping assembly 1 to facilitate the installation of the drainage mechanism.

[0041] In some embodiments, the washing and drying machine further includes a drain pipe 6 ; the drain pipe 6 is connected to an end of the water pipe 3 away from the pumping assembly 1 , so as to facilitate the installation of a drainage mechanism.

[0042] In this embodiment, a drainage pipe 6 is provided at one end of the water pipe 3 away from the pumping assembly 1 , thereby facilitating the connection of the drainage mechanism with the sewer.

[0043] In some embodiments, the washing and drying machine further includes a drain pipe 6 ; the drain pipe 6 is connected between the water pipe 3 and the pumping assembly 1 ; and the end of the water pipe 3 away from the pumping assembly 1 is also connected to the drain pipe 6 .

[0044] In this embodiment, by connecting a drain pipe 6 between the water pipe 3 and the pumping assembly 1, and providing a drain pipe 6 at the end of the water pipe 3 away from the pumping assembly 1, the installation of the drainage mechanism is facilitated, and the connection of the drainage mechanism with the sewer is also facilitated.

[0045] In some embodiments, the flow regulating assembly 2 includes a shell 22 having a first opening at one end, and the water pipe 3 has a second opening. The shell 22 is arranged on the water pipe 3, and the first opening is aligned with the second opening. The valve core unit 21 extends into the water pipe 3 through the first opening and the second opening.

[0046] In some embodiments, the other end of the housing 22 has a third opening, and the other end of the pressure transmission tube 4 is connected to the third opening.

[0047] In some embodiments, the valve core unit 21 includes a valve stem 211 and a core head 212. The valve stem 211 is arranged in the shell 22 and passes through the first opening and the second opening holes. The core head 212 is arranged at the end of the valve stem 211 facing the first opening. A flexible partition layer 213 is connected between the end of the valve stem 211 away from the first opening and the inner wall of the shell 22, which drives the valve stem 211 to move by water pressure. The flexible partition layer 213 facilitates water pressure to push the valve stem 211 to drive the core head 212 to adjust the opening of the water pipe 3, thereby solving the problem of water discharged from the washing and drying machine overflowing when the sewer is blocked or the sewer pipe diameter is small, and avoiding water overflow caused by the washing and drying machine draining too quickly and the water is not discharged in time.

[0048] In some embodiments, the washer-dryer further includes a control module, a pressure sensor 5 is provided at the end of the valve stem 211 away from the first opening, and the pressure sensor 5 and the pumping assembly 1 are both connected to the control module to close the pumping assembly 1 when the pressure difference obtained by the pressure sensor 5 reaches a first preset value.

[0049] In this embodiment, a pressure sensor 5 is provided at the end of the valve stem 211 away from the first opening to obtain the hydraulic pressure value transmitted from the pressure transmission tube 4 to the flow regulating assembly 2. Both the pressure sensor 5 and the pumping assembly 1 are connected to the control module. Pumping assembly 1 can be shut down when the hydraulic pressure value detected by the pressure sensor 5 reaches a first preset value. The first preset value is the hydraulic pressure value transmitted from the pressure transmission tube 4 to the flow regulating assembly 2 when the valve core unit 21 completely closes the water pipe 3.

[0050] In some embodiments, the washer-dryer further includes a display module, and the pressure sensor 5 is connected to the display module for displaying the hydraulic value transmitted from the pressure transmission pipe 4 to the flow regulating component 2. When the hydraulic value reaches a second preset value, the display module will sound an alarm and stop running until maintenance personnel perform inspection and repairs.

[0051] In some embodiments, the washer-dryer further includes a display module; a liquid level detection module is disposed within the barrel assembly and is connected to the display module. When the liquid level detection module detects that the difference in the liquid level within the barrel assembly before and after a preset time is less than a third preset value, the display module issues an alarm and stops operation until maintenance personnel can inspect and repair the machine.

[0052] Specifically, when the drainage speed of the sewer slows down, the pressure transmitted from the pressure transmission pipe 4 to the flow regulating component 2 increases, the flow regulating component 2 adjusts the opening of the pressure transmission pipe 4 to become smaller, and the drainage speed also slows down. The water level in the barrel assembly gradually rises or remains unchanged. The difference in water level before and after drainage is too small (less than the third preset value), and the washing and drying machine displays drainage timeout and automatically reports a fault.

[0053] When the drainage speed of the sewer is normal or has little impact, the pressure transmitted from the pressure transmission pipe 4 to the flow regulating component 2 changes little, the opening of the pressure transmission pipe 4 changes little, and the drainage speed fluctuates little, that is, the water level change before and after drainage is within the normal range (greater than the third preset value), and the washing and drying machine operates normally.

[0054] In some embodiments, the flow regulating assembly 2 further includes a seal 23, which is disposed at the first opening. A fourth through hole is provided on the seal 23, and the valve stem 211 is passed through the fourth through hole to improve the sealing performance between the valve stem 211 and the first opening seal 23.

[0055] In some embodiments, the flow regulating component 2 also includes an elastic member 24, which is clamped between the seal 23 and the pressure sensor 5. When the pressure of the water pipe 3 on the side of the flow regulating component 2 away from the pumping component 1 changes, the flow regulating component 2 drives the valve core unit 21 to adjust the opening of the water pipe 3 to become larger, thereby ensuring that water is discharged in time.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
