Problems solved by technology

However, this technology does not take into account the impact of environmental noise. In fact, in a noisy environment, the noise of the refrigerator has minimal impact on the user, and there is no need to reduce the noise. In the quiet night, although there are no users around the refrigerator, Still need to keep the running noise low

specific Embodiment 1

[0050] In this implementation, the noise sensor is used to sense the noise value around the refrigerator, and the collected noise value is sent to the controller to judge the noise level. The controller is provided with Z1 and Z2 values. In this embodiment, the The Z1 value is set to 30dB(A), and the Z2 value is set to 50dB(A).

[0051] Based on the adjustable speed of the inverter compressor, in this embodiment, N0 is the compressor speed during normal cooling operation, and F0 is the speed of the condensing fan during normal cooling operation. In this embodiment, the speed of the compressor is 3000rpm, and the speed of the condensing fan is 1320rpm; N1 is 900rpm, N2 is 600rpm, F1 is 120rpm, F2 is 100rpm, T1 is set to 1 minute, T2 is set to 30 minutes, and T3 is set to 240 minutes.

[0052] The control program rules in this example are as follows:

[0053] A) When the ambient noise is “noisy” (ZY≥50dB(A)), the compressor runs at 3000rpm, and the condensing fan runs at 1320rp...

Abstract

The invention discloses a refrigerator dynamic noise reduction control method. According to the method, a human body infrared sensor detects whether a person exists around a refrigerator or not, and asignal is transmitted to a controller; a noise sensor collects the noise value around the refrigerator, and the signal is transmitted to a controller; the controller has three compressor parameters,three condensation fan parameters and three timer parameters, according to the environment noise level and the human body infrared signal, whether the running rotating speed of a compressor and a condensation fan is adjusted or not is analyzed, and when a user is not nearby the refrigerator, a control program analyzes and determines the running rotating speed of the compressor and the condensationfan. The human body infrared sensor is arranged to induce whether the person is nearby the refrigerator or not, through the noise sensor, the environment noise around the refrigerator is collected, through the controller, according to the signals of the human body infrared sensor and the noise sensor, running power of the compressor and the condensation fan of the refrigerator is controlled, dynamic noise reduction of the refrigerator is achieved, and the user experience is improved.

Description

technical field [0001] The invention belongs to the field of refrigerator manufacturing, and in particular relates to a dynamic noise reduction control method for a refrigerator. Background technique [0002] With the development of society and the advancement of science and technology, refrigerators have not only reached a high level in terms of performance, but also become more and more beautiful in structure and appearance. However, in terms of user feedback, the problem of refrigerator noise still occupies a certain Complaint ratio, and has attracted the attention of major manufacturers. [0003] Chinese invention patent CN201610766539.7 discloses an infrared-based refrigerator noise reduction method, which uses an infrared sensor to detect the approach of a human body near the refrigerator, and reduces the operating speed of the compressor through the logical operation of the display board and the main control board, thereby reducing noise. However, this technology doe...
