Detailed Description

The invention will be further explained with reference to the drawings.

The invention provides a lamplight temperature feedback method of a dish washer, which comprises the following steps: acquiring the temperature of an inner cavity of the dish washer, and displaying a corresponding color by the full-color lamp according to the temperature; so that the temperature of the inner cavity of the dishwasher can be intuitively perceived by a user.

In the working process of the dishwasher or immediately after the washing, because the temperature of the tableware is higher, the user is not advised to take the tableware directly, the scalding situation is avoided, the user is usually instructed to wait for 30 minutes after the washing is finished and then take the washed tableware out, in the process, the user needs to confirm when the washing is finished and confirm that the washing is finished for 30 minutes, and the display is very inconvenient for the user who urgently uses the tableware; according to the invention, a user can intuitively feel whether the temperature of the washed tableware is suitable for taking or not by observing the color displayed by the full-color lamp only after opening the cabinet door of the dish washing machine.

In one embodiment, the method for light feedback temperature of a dishwasher further comprises, before the lighting system displays the corresponding color of light:

judging whether a cabinet door of the dishwasher is opened or not;

and when the door of the dishwasher is opened, starting the lighting system to display the light with the corresponding color.

It should be noted that, because full-color lamp during operation can consume the electric energy, and full-color lamp sets up in the inside of dish washer, sets up full-color lamp and works when the cabinet door is opened, can reduce the waste of the energy.

In one embodiment, the full-color lamp displays corresponding colors according to the temperature, and comprises:

and the control module calculates the RGB value corresponding to the current temperature of the inner cavity of the dish-washing machine and outputs the corresponding PWM value to the full-color lamp according to the RGB value.

It should be noted that, because the full-color lamp is based on three primary colors, most colors can be obtained by mutually combining different brightnesses of red, green and blue, that is, the current temperature of the inner cavity of the dishwasher is converted into corresponding RGB values, so that the full-color lamp can display different colors, and the current temperature conditions of the inner cavity and the tableware to be washed are further represented.

In one embodiment, calculating a corresponding target RGB value from the value of the target temperature comprises:

when the value of the target temperature is not greater than the lower temperature limit value, assigning the target RGB value as R being 255, G being 255 and B being 255;

when the value of the target temperature is not less than the upper temperature limit value, assigning RGB values as R being 255, G being 0 and B being 0;

when the value of the target temperature is larger than the lower temperature limit value and smaller than the upper temperature limit value, assigning the value R to be 255 and calculating the value G and the value B through the following calculation formula:

wherein: X-G values or B values; t-value of target temperature; t-lower temperature limit; a-upper limit of temperature.

It should be noted that, because there are 256 brightness levels from 0 to 255 in the RGB color brightness, these 256 brightness levels are equally divided by an upper limit value and a lower limit value and used as coefficients, and the product of the 256 brightness levels and the difference value between the upper limit value and the current temperature is converted into corresponding RGB values, when T ≧ a, X is ≦ 0, at this time, the smallest value 0 in RGB is taken as the value of X; therefore, the RGB color mode is equally divided, so that different cavity temperatures can correspond to different levels of RGB color brightness, and the full-color lamp can display different colors.

In one embodiment, the upper limit value is the maximum washing temperature of the dishwasher.

It should be noted that, in the operating process of the dishwasher, the temperature of the inner cavity of the dishwasher shows a variation trend of rising from the room temperature to the highest washing temperature and then falling to the room temperature, and the highest washing temperature parameter of the dishwasher is set as an upper limit value, so that the temperature of the inner cavity of the dishwasher completely covers all levels of color brightness of RGB, and further, the temperature coefficient division is more accurate.

In one embodiment, the lower limit value is a human body temperature value.

It should be noted that the temperature of dish washer inner chamber is the same with human body temperature value, can not cause the scald to the user at all promptly, consequently regard as the lower limit value with human body temperature value, reduces the quantity that RGB color luminance is hierarchical, promptly the dish washer inner chamber temperature is the same with human body temperature value, full-color lamp shows safe color, reduces user's latency.

In one embodiment, the RGB value corresponding to the current temperature is assigned to the G value and the B value of the full-color lamp through PWM.

Specifically, the G value and the B value of the full-color lamp are equal and change along with the change of the inner cavity of the dishwasher, so that the full-color lamp can present colors with different light and shade intensities under the same color system, and a user can visually feel the temperature of the inner cavity of the dishwasher.

It should be noted that, the color control module in the full-color lamp respectively adjusts the duty ratios of the PMW signals of the two primary colors of green (G value) and blue (B value) according to the RGB values, and simultaneously transmits the duty ratios of the PWM signals to the LED driving module, so as to drive the full-color lamp to obtain the color corresponding to the current temperature of the inner cavity, and maintain the red primary color (R value) of the full-color lamp in the red system of 255, so that the color of the full-color lamp is gradually deepened along with the increase of the temperature, thereby obviously warning the user.

In one embodiment, the upper limit value is set to be the highest washing temperature of 80 ℃, the lower limit value is set to be the human body temperature value of 36 ℃, then when the temperature of the inner cavity of the dishwasher is 80 ℃, namely X is 0, then the R value corresponding to the current temperature is 255, the G value and the B value are both 0, the LED driving module drives the full-color lamp to display the corresponding color, namely, the displayed red color with the obvious warning effect is used for reminding a user that the tableware to be washed cannot be directly taken at the moment.

In one embodiment, the upper limit value is set to be the maximum washing temperature of 80 ℃, the lower limit value is set to be the human body temperature value of 36 ℃, then when the temperature of the inner cavity of the dishwasher is 36 ℃, namely X is 255, then the R value, the G value and the B value corresponding to the current temperature are 255, the LED driving module drives the full-color lamp to display the corresponding color, namely the displayed color is white, and the user is reminded to directly take the washing tableware at the moment.

It should be noted that when the temperature of the inner cavity of the dishwasher is acquired to be less than 36 ℃, that is, X is greater than 255, the highest value 255 of the RGB color brightness levels is taken to be assigned to the G value and the B value.

In one embodiment, the determining whether a door of a dishwasher is open includes:

the contact in the touch switch on the cabinet door is separated, namely the cabinet door is closed;

the contact is closed due to the fact that the touch switch is popped out under the action of the spring, namely, the cabinet door is opened.
