Description

A device for controlling the adjustment of the program of the washing machine according to the ambient temperature

technical field

The utility model relates to the technical field of washing machines, in particular to a device for controlling the program of the washing machine to be adjusted according to the ambient temperature.

Background technique

Most washing machines currently on the market do not have the function of adjusting the working program with the ambient temperature (water temperature). Even if some brand products have the function of adjusting the washing program with the temperature, it is not continuously adjusted, but divided into several different washing programs corresponding to the temperature range.

Although most of the drum washing machines have a heating function, they can only artificially set the heating washing program to improve the effect, and they cannot automatically adjust the program according to the ambient temperature to improve the washing effect.

Since the washing program of the existing washing machine cannot be adjusted with the ambient temperature, the washing program of the same washing machine is the same everywhere. However, our country has a vast geographical environment and large climate differences, so the user's environment has a large temperature difference, and the temperature difference between the north and the south can reach 30-40°C in the same season. The huge difference in ambient temperature causes the washing effect of clothes to be significantly different. The washing effect of clothes with high temperature in the washing environment is better than that in the environment with low temperature.

During the use of the same washing machine, due to the large temperature difference between the four seasons, in most of our country, the ambient temperature difference between summer and winter is above 30°C, which causes the same washing machine in the user's home to have different washing effects in different seasons. The effect is obviously better than winter.

Utility model content

The purpose of the utility model is to provide a device for controlling the adjustment of the program of the washing machine according to the ambient temperature, which can automatically adjust the washing program according to the ambient temperature, improve the washing effect and efficiency, and effectively reduce energy consumption.

In order to achieve the above object, the utility model adopts the following technical solutions:

A device for controlling the adjustment of the program of the washing machine according to the ambient temperature, comprising a detection module, a data processing module, a control module and a drive module connected in sequence, the detection module detects the water inlet temperature of the washing machine, and the data processing module receives the temperature detected by the detection module data and calculate the washing time, the control module adjusts the washing control program according to the washing time calculated by the data processing module, and sends the adjusted program instructions to the drive module, and the drive module drives the washing machine motor, water intake and drainage The system works to wash the clothes.

Preferably, the detection module is arranged at the water inlet of the washing machine.

Preferably, the detection module is a temperature sensor.

Beneficial effects of the utility model: the utility model does not change the structure of the washing machine, but adds a temperature sensor to the program controller of the washing machine, senses the ambient temperature during washing through the temperature sensor, and transmits the temperature value to the data processing module. Adjust the washing program to increase or decrease the washing time accordingly. The washing time is increased when the ambient temperature is low, and the washing time is shortened when the ambient temperature is high, so as to ensure that the washing effect is better at different ambient temperatures, and it also has the effect of saving energy.

Detailed ways

The technical solution of the present utility model will be further specifically described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, a device for controlling the adjustment of the program of the washing machine according to the ambient temperature, including a detection module, a data processing module, a control module and a drive module connected in sequence, the detection module detects the water inlet temperature of the washing machine, and the data processing module receives the detection module detection temperature data and calculate the washing time, the control module adjusts the washing control program according to the washing time calculated by the data processing module, and sends the adjusted program instructions to the drive module, which drives the washing machine motor, water inlet and drainage system to work on the laundry washing. The detection module in this embodiment uses a temperature sensor. In this embodiment, the detection module is arranged at the water inlet of the washing machine.

The relationship between washing machine cleanliness and water temperature is a very complicated functional relationship according to actual tests, but the basic logical relationship is that when the washing time is constant, the washing effect will be better as the water temperature increases. For the convenience of realization and quantification, the water temperature and washing time are now simplified into two negative linear relationship functions, that is, the higher the water temperature, the shorter the washing time.

The functional relationship of the present embodiment washing time and water temperature is determined in the following way:

Let the washing time be Y, and the water temperature be t.

A. Determination of the relationship between washing time and temperature below 20°C:

Let the washing time at normal temperature (20°C) be T20, and the washing time at 0°C to achieve the same degree of cleanliness is T0. Determined according to the negative correlation linear function relationship, the change function of washing time and water temperature is Y=-(T0-T20)t+T0.

B. Determination of the relationship function between washing time and temperature above 20°C:

Assume that the washing time at normal temperature (20°C) is T20, and the washing time at 40°C to achieve the same degree of cleanliness is T40. According to the negative correlation linear function relationship, the change function of washing time and water temperature is Y=-(-T40)t+(2T20-T40).

The detection module of this embodiment is set at the water inlet of the washing machine. After detecting the water temperature of the incoming water, the temperature data is sent to the data processing module. wash time. The control module realizes the adjustment of the washing program according to the calculated washing time. Finally, the control module sends the adjusted program instructions to the drive module, and the drive motor, water inlet and drainage systems work together to wash the clothes. Thereby, the uniformity of the washing effect (cleaning degree) at different ambient temperatures is improved, and the energy efficiency of the complete machine washing at a relatively high ambient temperature is also improved.

(2) For a washing machine with a heating function (including a pulsator and a drum), when a heating program is selected, the washing machine program controller (MCU) stops the temperature sensor from working until the washing program ends. That is, when the washing program with heating is set, the washing time will no longer be adjusted with the ambient temperature.

Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to preferred embodiments, those of ordinary skill in the art should understand that this utility model can be Any modification or equivalent replacement of the technical solution of the utility model without departing from the spirit and scope of the technical solution of the utility model shall be covered by the claims of the utility model.
