Problems solved by technology

[0002] At present, the detergent of the dishwasher is usually put in quantitatively. When there are many and dirty tableware, the amount of detergent is not enough, and the washing time needs to be increased, which consumes more time and water; when the tableware is less and cleaner When using more detergent, it is necessary to increase the rinsing time, which also takes time and consumes more water, which is not economical and environmentally friendly.

Embodiment 1

[0030] Such as figure 1 As shown, this embodiment provides a dishwasher delivery control device, including:

[0031] The turbidity sensor 200, the weight sensor 500, the A / D converter 300, the control unit 100, and the solenoid valve driving unit 400, the turbidity sensor 200 and the weight sensor 500 are arranged in the washing cavity of the dishwasher, and the A / D The input end of D converter 300 is connected with the output end of described turbidity sensor 200 and weight sensor 500 respectively, and the output end of described A / D converter 300 is connected with the input end of described control unit 100, and described control unit The output end of 100 is connected with the solenoid valve driving unit 400;

[0032] The turbidity sensor 200 is used to detect the degree of dirtiness of the tableware in the washing chamber of the dishwasher and transmits it to the A / D converter 300, and the weight sensor 500 is used to detect the weight of the tableware in the washing cham...

Embodiment 2

[0044] This embodiment provides a dishwasher. The dishwasher includes a dishwasher main body and a detergent delivery device. The detergent delivery device communicates with the washing cavity of the dishwasher main body. The outlet of the device is provided with a detergent injection solenoid valve; the dishwasher also includes the aforementioned dishwasher detergent injection control device. The detergent dispensing control device is used to control the opening or closing of the detergent dispensing solenoid valve. Its specific structure and beneficial effects are all referred to in Embodiment 1, and will not be repeated here.

Embodiment 3

[0046] Such as figure 1 , figure 2 As shown, this embodiment provides a method for controlling the dosage of dishwasher detergent, which is applied to the dishwasher described in Embodiment 2. The control method includes the following steps:

[0047] Step S101, detecting the degree of dirtiness of the tableware and the weight of the tableware in the washing cavity of the dishwasher, and converting them into corresponding voltage signals and transmitting them to the control unit;

[0048] In step S102, the control unit outputs a corresponding control signal according to the received voltage signal, and the detergent dispensing solenoid valve continues to open for a corresponding period of time according to the control signal.

[0049] In this embodiment, the degree of dirtiness of the tableware is usually achieved by detecting the degree of dirtiness of the washing water in the washing chamber of the dishwasher. The turbidity is caused by suspended particles in the water, whi...

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a dishwasher and a detergent injection control device and method thereof. Background technique [0002] At present, the detergent of the dishwasher is usually put in quantitatively. When there are many and dirty tableware, the amount of detergent is not enough, and the washing time needs to be increased, which consumes more time and water; when the tableware is less and cleaner When using more detergent, it is necessary to increase the rinsing time, which also consumes time and a large amount of water, which is not economical and environmentally friendly. Contents of the invention [0003] The present invention aims to solve one of the problems existing in the related art at least to a certain extent. Therefore, the present invention proposes a dishwasher detergent injection control device and a dishwasher including the injection control device. The corresponding am...
