Problems solved by technology

[0004]However, the above-mentioned water level detection structure is relatively complicated, and the assembly process is relatively cumbersome, and it is prone to air leakage between the detection pipeline and the air chamber, as well as between the detection pipeline and the sensor
As a result, the accuracy of detection is affected, causing the failure of the whole machine, and the complex structure also leads to high costs

Embodiment 1

[0031] like Figure 1 to Figure 3 As shown, this embodiment introduces a drain valve plug 300, which includes a valve plug housing 2, a rubber valve plug core 1 that can move axially and telescopically is installed in the valve plug housing 2, and the telescopic end of the rubber valve plug core 1 A pressure sensor 3 is installed, and the pressure sensor 3 detects the water pressure at the telescopic end of the rubber valve plug core 1 .

[0032] By installing a pressure sensor at the end of the rubber valve plug core of the drain valve plug, the water pressure at the drain port blocked by the drain valve is detected, and then the liquid water level in the corresponding installation container of the drain valve is obtained to realize integrated controllable opening and closing of drainage Dual function of valve and level detection.

[0033] In this embodiment, the pressure sensor 3 communicates with the external water flow through the pressure guiding block 4 made of high ela...

Embodiment 2

[0044] The difference between this embodiment and the first embodiment above is that the pressure sensor is directly sealed inside the rubber valve plug core. The rubber valve plug includes a push-pull rod and a set of sealing sleeves on the telescopic end of the push-pull rod. The pressure sensor is clamped between the telescopic end of the push-pull rod and the sealing sleeve. The sealing sleeve is made of elastic materials such as rubber, so that the external water pressure is elastically The sealing sleeve is transmitted to the pressure sensor, so that the pressure sensor can indirectly detect the external water pressure through the sealing sleeve, and then realize the purpose of detecting the external water pressure of the drain valve plug; at the same time, the pressure sensor can also be sealed in the sealing sleeve , to prevent the pressure sensor from contacting with water.

Embodiment 3

[0046] The difference between this embodiment and the above-mentioned first embodiment is that the top cover is made of elastic material, and there is no pressure guide port on it, and the pressure sensor is clamped between the top cover and the push-pull rod to obtain the external water pressure through the elastic top cover. It is transmitted to the pressure sensor, so that the pressure sensor can indirectly detect the external water pressure through the top cover, and then realize the purpose of detecting the external water pressure of the drain valve plug; at the same time, the pressure sensor can also be sealed in the top cover to prevent pressure Occurrence of sensor contact with water.

Abstract

The invention introduces a drain valve plug which comprises a valve plug casing, wherein a rubber valve plug core capable of axially telescopically moving is installed in the valve plug casing, a pressure sensor is installed at the telescopic end of the rubber valve plug core, and the pressure sensor detects water pressure at the telescopic end of the rubber valve plug core. The invention furtherintroduces a washing machine comprising an outer barrel and an inner barrel sleeved with the outer barrel, the bottom of the inner barrel is provided with a water outlet, any one of the drain valve plugs described as above is mounted on the outer barrel, the valve plug casing is mounted on the outer barrel of the washing machine, and the rubber valve plug core capable of axially telescopically moving is installed in the valve plug casing, to control the rubber valve plug core to correspondingly close the water outlet disposed at the bottom of the inner barrel. The pressure sensor disposed at the telescopic end of the rubber valve plug core extends into the inner barrel, to detect the washing water pressure in the inner barrel, thereby obtaining washing water level in the inner barrel of the washing machine and achieving accurate detection of the water level in the inner barrel. At the same time, the drain valve plug has simple structure and remarkable effect, and is suitable for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of non-porous washing machine equipment, and in particular relates to a valve plug with a pressure sensor, and also relates to a washing machine equipped with the above-mentioned drain valve plug. Background technique [0002] At present, in order to save water resources, more and more washing machines adopt the method of non-porous inner tub. When washing, there is no water between the inner tub and the outer tub. The inner tub is a washing tub, and the outer tub is a drainage tub. Some non-porous inner tub pulsator washing machines, due to structural limitations, water level detection is difficult to achieve. [0003] For example, the technical solution adopted by the applicant before: a washing machine, the inner bucket is an integral water storage bucket, the outer bucket is a drain bucket, a water storage cavity is formed between the inner bucket, the outer bucket and the deceleration clutch, and the in...
