Based on the hardware structure, the embodiment of the air pressure control method of the drawer type dishwasher is provided.
Referring to fig. 2, fig. 2 is a flow chart illustrating a first embodiment of an air pressure control method of a drawer type dishwasher according to the present invention.
In this embodiment, an air pressure sensor and a heating device are disposed at the bottom of a drawer of the drawer dishwasher, and the air pressure control method of the drawer dishwasher includes the following steps:
step S10, when the heating device of the target drawer is detected to be in a heating state, acquiring the current air pressure value of the target drawer as a first air pressure value through the air pressure sensor of the target drawer, and judging whether the first air pressure value is larger than a first preset threshold value;
at present, the rotation of a motor of a drawer dishwasher causes a top cover plate to rotate, thereby compressing the top cover plate of the drawer dishwasher. But when using dish washer, if other heating devices such as the heating pipe of dish washer or temperature-detecting device break down, arouse the heating pipe to continue to heat to the high temperature that leads to the drawer inner bag causes the atmospheric pressure of drawer inner bag too high easily, and too high atmospheric pressure backs up the apron easily and leads to the hot water blowout, thereby leads to the easy incident that takes place to scald the user, has reduced user experience. In the embodiment, the air pressure sensor is arranged on the target drawer, and the air pressure sensor is a non-contact sensor, so that the installation method is simple, and the air pressure sensor can be arranged at any position of the liner, such as the surface layer of the liner. The air pressure control method of the drawer type dishwasher can be directly applied to the drawer type dishwasher or other electronic products provided with the air pressure control program of the drawer type dishwasher. When the air pressure control device of the drawer type dishwasher detects that the heating device corresponding to the target drawer of the drawer type dishwasher is heating, if the drawer type dishwasher is executing a washing and heating function, the current air pressure value of the target drawer is obtained through the air pressure sensor arranged on the target drawer, and the current air pressure value is used as a first air pressure value. And comparing the first air pressure value with a first preset threshold value so as to judge whether the first air pressure value is greater than the first preset threshold value. The first preset threshold is an air pressure threshold for normal operation of the dishwasher, and when the dishwasher exceeds the air pressure threshold, namely the current air pressure of the dishwasher is slightly higher, the problem of overflow of hot water is easily caused. When the dishwasher operates at the air pressure lower than the first preset threshold value, namely the current operating air pressure of the dishwasher is the normal air pressure. The first preset threshold value can be set by a worker according to actual conditions.
Further, before step S10, the method further includes:
when a control instruction is detected, determining a target drawer according to a drawer identifier in the control instruction, and opening a heating device of the target drawer according to the control instruction.
Specifically, the water quantity control device of the drawer type dishwasher acquires a drawer identifier in a control instruction when detecting that the drawer type dishwasher receives the control instruction, and then determines a target drawer according to the drawer identifier. And according to the control instruction, opening a heating device of the target drawer to heat the target drawer. Wherein the control instruction is a function instruction requiring the use of the heating device, such as a washing heating function.
Further, step S10 specifically includes:
when the heating device of the target drawer is detected to be in a heating state, the current AD value of the target drawer is obtained in real time through the air pressure sensor;
specifically, after the heating device of the target drawer is opened, or when the heating device of the target drawer is detected to be in a heating state, the current air pressure value of the target drawer is detected. Firstly, the current voltage value of the target drawer is obtained through an air pressure sensor arranged in an inner container of the target drawer, and the current voltage value is converted into a current AD value.
And converting the current AD value into a current air pressure value serving as the first air pressure value, and judging whether the first air pressure value is greater than a first preset threshold value.
Specifically, the current AD value is converted into a corresponding current air pressure value according to a detection circuit, the current air pressure value is used as the first air pressure value, and whether the first air pressure value is a normal value is determined according to a preset first preset threshold value.
Step S20, if the first air pressure value is greater than the first preset threshold, controlling the operating state of the heating device of the target drawer according to a preset rule, so as to control the air pressure value of the target drawer within the first preset threshold.
Specifically, when the first air pressure value is greater than the first preset threshold, that is, the current air pressure in the target drawer is greater, the current air pressure of the target drawer should be adjusted. The heating device can be suspended to enable the temperature in the target drawer to be rapidly reduced because the air pressure is high because the temperature in the target drawer is too high; or the heating device is subjected to intermittent heating operation at preset time intervals so as to slightly reduce the temperature in the target drawer without influencing the work of the target drawer.
The implementation provides an air pressure control method and device of a drawer type dish washing machine and a computer readable storage medium, wherein an air pressure sensor and a heating device are arranged on a drawer of the drawer type dish washing machine, and the air pressure control method of the drawer type dish washing machine obtains a current air pressure value of a target drawer as a first air pressure value through the air pressure sensor of the target drawer when the heating device of the target drawer is detected to be in a heating state, and judges whether the first air pressure value is larger than a first preset threshold value or not; if the first air pressure value is larger than the first preset threshold value, controlling the working state of the heating device of the target drawer according to a preset rule so as to control the air pressure value of the target drawer within the first preset threshold value. Through the mode, the air pressure condition of the dish washing machine is accurately monitored in real time through the air pressure sensor, the abnormal condition of the heating device is detected in time, the condition that the air pressure is too high due to continuous abnormal heating of the heating device is avoided, and the technical problem that the existing drawer type dish washing machine is easy to have too large air pressure is solved.
Referring to fig. 3, fig. 3 is a flow chart illustrating a second embodiment of an air pressure control method of a drawer type dishwasher according to the present invention.
Based on the foregoing embodiment shown in fig. 2, further, in this embodiment, step S20 specifically includes:
step S21, if the first air pressure value is greater than the first preset threshold, determining whether the first air pressure value is less than a second preset threshold, where the first preset threshold is less than the second preset threshold;
specifically, an air pressure threshold of the target drawer under the corresponding function, that is, a second preset threshold, is obtained, and when the air pressure value in the target drawer reaches the second preset threshold, that is, it indicates that the current air pressure value in the target drawer is a high air pressure value, a rapid cooling operation needs to be performed to rapidly reduce the air pressure in the target drawer. And comparing the first air pressure value with the first preset threshold, and when the first air pressure value is judged to be lower than the first preset threshold, comparing the first air pressure value with the second preset threshold, and judging whether the first air pressure value is larger than the second preset threshold. When the dishwasher is operated above the second preset threshold, the current air pressure of the dishwasher is high. And when the dishwasher works with the air pressure of the second preset threshold value, the dishwasher needs to be immediately cooled, so that the air pressure in the dishwasher is reduced. The second preset threshold value can be set by a worker according to actual conditions.
Step S22, if the first air pressure value is smaller than the second preset threshold value, controlling the heating device of the target drawer to intermittently heat according to a first preset time interval so as to reduce the air pressure value of the target drawer;
specifically, when the first air pressure value does not exceed a second preset threshold value, that is, the first air pressure value is greater than the first preset threshold value and less than the second preset threshold value, that is, the current temperature value of the dishwasher is high, although a dangerous problem is not immediately generated, when the target drawer continues to be heated, the temperature of the target drawer is easily too high. Therefore, according to the preset time interval, the heating device of the target drawer intermittently heats at the preset time interval. Namely, after heating for a period of time, suspending heating, and then continuing heating, thereby circulating until the air pressure value of the target drawer is reduced below the first preset threshold value, so that the heating device can be recovered to a normal heating state, namely, heating is continuously carried out in a fixed mode.
Step S23, if the first air pressure value is greater than the second preset threshold, the heating device of the target drawer is turned off to rapidly decrease the air pressure value of the target drawer.
Specifically, when it is determined that the first air pressure value is greater than the first preset threshold, that is, the current air pressure in the target drawer is large, the temperature in the target drawer is high. This situation is prone to the danger of the heating means of the target drawer being turned off, preventing the temperature in the target drawer from continuing to rise and the air pressure from continuing to increase. Specifically, the exhaust area of the target drawer can be increased, so that the target drawer is rapidly cooled, and the air pressure of the target drawer is rapidly reduced.
Further, after step S23, the method for controlling air pressure of a drawer type dishwasher further includes:
and when the first air pressure value is detected to be smaller than the second preset threshold value, the heating device is started, and the step S21 is executed in a returning mode.
Specifically, after the heating device of the target drawer is closed, the heating for the target drawer is stopped. And after detecting that the air pressure value of the target drawer is reduced to a second preset threshold value, controlling the heating device to intermittently perform heating operation so as to facilitate the operation of the drawer type dishwasher.
Further, after step S20, the method for controlling air pressure of a drawer type dishwasher further includes:
and when the first air pressure value is detected to be smaller than the first preset threshold value, controlling a heating device of the target drawer to heat in a normal heating mode.
Specifically, when it is determined that the first air pressure value is lower than the first preset threshold, that is, the air pressure value in the target drawer is a normal value, the heating device of the target drawer is controlled to heat in a normal heating mode. That is, the heating means of the target drawer may heat the wooden target drawer in a conventional heating manner.
Referring to fig. 4, fig. 4 is a flow chart illustrating a third embodiment of an air pressure control method of a drawer type dishwasher according to the present invention.
In this embodiment, after step S20, the method for controlling air pressure of a drawer type dishwasher further includes:
step S31, according to a second preset time interval, acquiring the current air pressure value of the target drawer as a second air pressure value through the air pressure sensor of the target drawer, and judging whether the second air pressure value is greater than the first preset threshold value;
specifically, when the air pressure value of the target drawer is adjusted according to the working state of the heating device, whether the air pressure value in the target drawer is reduced to a normal value within a preset time is judged. After the heating device of the target drawer is controlled to pause or intermittently operate for a preset time, the current air pressure value of the target drawer is obtained and used as a second air pressure value, and the second air pressure value is compared with the first preset threshold value.
And step S32, if the second air pressure value is greater than the first preset threshold value, determining that the drawer type dishwasher has heating fault, and disconnecting the power supply of the drawer type dishwasher to turn off the drawer type dishwasher.
Specifically, if the second air pressure value is greater than the first preset threshold, it indicates that the drawer type dishwasher cannot perform cooling and depressurization, or the time for cooling and depressurization is too long. That is, the heating device of the drawer dishwasher may malfunction, and in order to avoid abnormal heating and thus accidents, the power of the drawer dishwasher is disconnected to turn off the drawer dishwasher, so that the drawer dishwasher stops operating.
Further, after step S32, the method further includes:
and when the heating fault of the drawer type dish washing machine is judged, displaying a heating fault reminding message to remind a user of heating fault maintenance.
Specifically, when it is detected that the drawer type dishwasher cannot lower the temperature and lower the pressure, or the time for lowering the temperature and lowering the pressure is too long, it is determined that a heating device of the drawer type dishwasher or other heating devices, such as a thermometer for detecting the temperature, has a fault, and the drawer type dishwasher is required to be overhauled in time.
Further, after step S20, the method further includes:
when the heating device of the target drawer is detected to be in a closed state, acquiring a current air pressure value of the target drawer as a third air pressure value through an air pressure sensor of the target drawer, and judging whether the third air pressure value is greater than a third preset threshold value, wherein the third preset threshold value is smaller than the first preset threshold value;
specifically, when the drawer dishwasher performs a corresponding function operation, such as a drying function, and the drying function operation is completed, air pressure inside the target drawer is easily changed into negative pressure due to air being drawn out of the target drawer.
