Detailed ways

The embodiments of the present invention are described in detail below, and the embodiments of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

Referring to FIG. 1 and FIG. 2 together, the control method of the embodiment of the present invention can be used to control the dishwasher 100. The dishwasher 100 includes a housing 110, a fan 120, a temperature detecting unit 130, and a humidity detecting unit 140. The housing 110 is provided with a working chamber 111 and a communication working chamber 111 and an external air duct 112. The temperature detecting unit 130 and the humidity detecting unit 140 are respectively used for detecting the temperature and humidity of the working chamber 111. The fan 120 is used to establish an air flow through the air duct 112 to ventilate the working chamber 111. The control method includes the following steps:

S151: After the washing of the dishwasher 100 is finished, the control temperature detecting unit 130 detects that the temperature and humidity detecting unit 140 detects the humidity;

S152: Calculating the dew point temperature according to temperature and humidity; and

S153: Control the fan 120 to operate for a second predetermined time after stopping the first predetermined time after the washing of the dishwasher 100 according to the difference between the temperature and the dew point temperature, the difference is positively correlated with the first predetermined time, and the difference is the second The scheduled time is inversely related.

Referring to FIG. 2 again, the dishwasher 100 of the embodiment of the present invention includes a housing 110, a fan 120, a temperature detecting unit 130, a humidity detecting unit 140, and a processor 150. The housing 110 is provided with a working chamber 111 and an air passage 112 that communicates with the working chamber 111 and the outside. The fan 120 is used to establish an air flow through the air duct 112 to ventilate the working chamber 111. The temperature detecting unit 130 is for detecting the temperature of the working chamber 111. The humidity detecting unit 140 is for detecting the humidity of the working chamber 111. The processor 150 is configured to:

The control temperature detecting unit 130 detects that the temperature and humidity detecting unit 140 detects the humidity after the washing of the dishwasher 100 is completed;

Calculate the dew point temperature based on temperature and humidity; and

Controlling the fan 120 to operate for a second predetermined time after the first predetermined time of stopping after the washing of the dishwasher 100 is stopped according to the difference between the temperature and the dew point temperature, the difference being positively correlated with the first predetermined time, the difference being the second predetermined time Anti-correlation.

That is, the control method of the embodiment of the present invention can be implemented by the dishwasher 100 of the embodiment of the present invention, wherein steps S151, S152, and S153 can be implemented by the processor 150.

The control method of the dishwasher 100 and the dishwasher 100 of the embodiment of the present invention calculate the dew point temperature using the humidity detected by the temperature and humidity detecting unit 140 detected by the temperature detecting unit 130, and control the fan 120 according to the temperature and the dew point temperature, thereby Avoid condensation of water vapor into water droplets and make the tableware damp.

In some embodiments, due to space limitations of the working chamber 111, such as the working chamber 111 being small, the temperature detecting unit 130 and the humidity detecting unit 140 cannot be directly installed in the working chamber 111, and therefore, the temperature detecting unit can be The 130 and humidity detecting unit 140 is installed in the air duct 112, and the temperature detecting unit 140 in the air duct 112 detects the humidity in the air duct 112 by the temperature detecting unit 130. The working chamber refers to a component in the dishwasher 100 for placing dishes and washing dishes, also referred to as a liner. In certain embodiments, the temperature and humidity within the air duct 112 can be considered as the temperature and humidity of the working chamber 111.

In some embodiments, the temperature detecting unit 130 and the humidity detecting unit 140 may be directly disposed in the working chamber 111 to accurately acquire the temperature and humidity of the working chamber 111, which is not specifically limited herein.

In some embodiments, the fan 120 may be disposed within the dishwasher 100 or outside the dishwasher 100, which is not specifically limited herein. In one embodiment, the fan 120 is disposed in the air duct 112 such that air can be preferably directed through the air duct 112 into and out of the dishwasher 100.

In some embodiments, the end of washing of the dishwasher 100 means that the dishwasher 100 has finished the washing process. The washing process generally includes several procedures of pre-washing, main washing, rinsing, and drying, and the washing of the dishwasher 100 is generally Means that the drying process has ended. Steps S151, S152, and S153 of the embodiment of the present invention can be regarded as a storage program, and steps S151, S152, and S153 can be performed a plurality of times to keep the drying of the working chamber 111.

In some embodiments, temperature detection unit 130 includes a temperature sensor and humidity detection unit 140 includes a humidity sensor.

In this way, the temperature sensor can be used to quickly acquire the temperature, and the humidity sensor can be used to quickly obtain the humidity.

Specifically, the temperature sensor may be a temperature measuring device such as an electronic thermometer, and the humidity sensor may refer to a device for measuring the relative humidity of the air. It should be noted that the humidity detecting unit 140 is generally used for measuring relative humidity, and the dew point temperature can be calculated according to the temperature and the relative humidity. The dew point temperature refers to the temperature at which the air is cooled to saturation under the condition that the water vapor content and the air pressure are not changed. That is to say, the temperature at which water vapor in the air turns into dew is called the dew point temperature.

It can be understood that when the difference between the temperature and the dew point temperature is relatively large, it is indicated that the water vapor in the dishwasher 100 does not easily condense into water droplets, so that the fan 120 can be controlled to stop for a long time (ie, the first predetermined time is long) to operate. Shorter time (ie, the second predetermined time is shorter); when the difference between the temperature and the dew point temperature is small, it is indicated that the water vapor in the dishwasher 100 is easily condensed into water droplets, so that the fan 120 can be controlled to stop for a short time (ie, The predetermined time is shorter and the operation is longer (i.e., the second predetermined time is longer), thereby removing water vapor in the dishwasher 100, thereby preventing the water vapor from condensing into water droplets.

Referring to FIG. 3, in some embodiments, the control method includes the following steps before the washing of the dishwasher 100 ends:

S154: After the third predetermined time is stopped, the fifth predetermined time is stopped after the fourth predetermined time is stopped.

Referring again to FIG. 2, in some embodiments, processor 150 is configured to:

The fifth predetermined time is stopped after the control fan 120 stops for the third predetermined time and after the fourth predetermined time.

That is, step S154 can be implemented by the processor 150.

In this way, the dishes in the dishwasher 100 can be dried.

Specifically, prior to the end of washing of the dishwasher 100, the dishwasher 100 generally includes a drying procedure by which the water vapor content within the working chamber 111 can be substantially reduced. The drying process of the dishwasher 100 can be realized by controlling the fan 120 to stop after the third predetermined time of operation for a third predetermined time, that is, the drying process of the dishwasher 100 can be controlled after the third time is stopped by the control fan 120. Four scheduled time. It will be appreciated that in order to substantially reduce the water vapor content within the working chamber 111, the third predetermined time may be much less than the fourth predetermined time, and the fan 120 may be controlled multiple times to operate for a third predetermined time and a fourth predetermined time. It should be noted that the air in the working chamber 111 can also be dried by the steps S151, S152 and S153 of the embodiment of the present invention, but generally takes a long time, so that the third can be stopped by controlling the fan 120. The fourth predetermined time is operated after the predetermined time to dry the air in the working chamber 111 in a shorter time. In addition, after the working chamber 111 is dried by the fan 120, the water vapor content of the working chamber 100 is low in a short time, so that the fan 120 can be controlled to stop for a fifth predetermined time, such as 60 minutes, thereby reducing the dishwasher 100. Power consumption.

In some embodiments, the third predetermined time is about 5 minutes, the fourth predetermined time is about 40 minutes, and the fifth predetermined time is about 60 minutes.

In this way, the air in the working chamber 111 can be dried.

Specifically, when the fan 120 is controlled to dry the dishwasher 100 in a predetermined manner, generally the fan 120 stops for a shorter third predetermined time, such as about 0-10 minutes, preferably 5 minutes, and then runs longer. The fourth predetermined time, such as 30-60 minutes, may preferably be 40 minutes to sufficiently carry away the water vapor in the working chamber 111, thereby ensuring drying of the working chamber 111. After the fan 120 has dried the working chamber 111, the water vapor content of the working chamber 111 is low, and the fan 120 can be stopped for a fifth predetermined time, such as 50-70 minutes, preferably 60 minutes, at 60. After a minute, temperature and humidity can be detected, and the control method according to an embodiment of the present invention controls the operation of the fan 120 to perform the storage procedure of the dishwasher 100.

Referring to FIG. 4, in some embodiments, step S151 includes the following steps:

S1512: Control the fan 120 to operate for a sixth predetermined time after the washing of the dishwasher 100 and before the first predetermined time;

S1514: The control temperature detecting unit 130 detects that the temperature and humidity detecting unit 140 detects the humidity in the sixth predetermined time.

Referring again to FIG. 2, in some embodiments, processor 150 is configured to:

Controlling the fan 120 to operate for a sixth predetermined time after the washing of the dishwasher 100 and before the first predetermined time;

The control temperature detecting unit 130 detects that the temperature and humidity detecting unit 140 detects the humidity within the sixth predetermined time.

That is to say, steps S1512 and S1514 can be implemented by the processor 150.

In this way, the humidity detected by the temperature and humidity detecting unit 140 detected by the temperature detecting unit 130 can be made substantially the same as the temperature and humidity of the working chamber.

Specifically, the temperature detecting unit 130 and the humidity detecting unit 140 may be disposed in the air duct 112. When the temperature detecting unit 130 and the humidity detecting unit 140 are in operation, the fan 120 may be controlled to operate, so that the fan 120 drives the air in the working chamber 111. The air flowing in the air passage 112 can be regarded as the air in the working chamber 111, that is, the temperature detected by the temperature detecting unit 130 substantially coincides with the temperature of the working chamber 111, and the humidity detected by the humidity detecting unit 140 and the working chamber. The humidity of the chamber 111 is substantially the same.

It can be understood that the sixth predetermined time is between the end of washing of the dishwasher 100 and the first predetermined time. In some embodiments, the sixth predetermined time may refer to the last time of the fifth predetermined time, such as the fifth predetermined time. The last 20 seconds. In one embodiment, at the end of the washing sequence, the sixth predetermined time may refer to the last period of the fifth predetermined time, such as 20 seconds. In another embodiment, when steps S151, S152, and S153 are cyclically executed and the last first predetermined time and the second predetermined time have just ended, the sixth predetermined time may refer to the last time period of the last second predetermined time. For example, 20 seconds.

Referring to FIG. 5, in some embodiments, step S151 includes the following steps:

S1516: controlling the temperature detecting unit 130 to perform a plurality of times to obtain a plurality of initial temperatures and controlling the humidity detecting unit 140 to perform a plurality of times to obtain a plurality of initial humidity; and

S1518: processing a plurality of initial temperatures and a plurality of initial humidity to obtain temperature and humidity, the temperature being an intermediate value or an average value of the plurality of initial temperatures, and the humidity being an intermediate value or an average value of the plurality of initial humidityes.

Referring again to FIG. 2, in some embodiments, processor 150 is configured to:

Controlling the temperature detecting unit 130 to perform a plurality of times to obtain a plurality of initial temperatures and controlling the humidity detecting unit 140 to perform a plurality of times to obtain a plurality of initial humidity; and

The plurality of initial temperatures and the plurality of initial humidities are processed to obtain temperature and humidity, the temperature being an intermediate value or an average value of the plurality of initial temperatures, and the humidity being an intermediate value or an average value of the plurality of initial humidityes.

That is to say, steps S1516, S1518 can be implemented by the processor 151.

In this way, the accuracy of temperature and humidity can be guaranteed.

It can be understood that the temperature detecting unit 130 and the humidity detecting unit 140 can simultaneously detect to obtain an initial temperature and a corresponding initial humidity, and the plurality of initial temperatures and the plurality of initials can be obtained by the temperature detecting unit 130 and the humidity detecting unit 140 detecting multiple times. Humidity, temperature and humidity can be obtained by processing multiple initial temperatures and multiple initial humidityes. Specifically, a method of obtaining a plurality of initial temperatures and a plurality of initial humiditys to obtain temperature and humidity includes taking an average of a plurality of initial temperatures as a temperature and taking an average of a plurality of initial humidity as humidity, or taking a plurality of initial temperatures The median value is used as the temperature and the median value of the plurality of initial humidityes as the humidity, and the like is not specifically limited herein.

Further, the plurality of initial temperatures and the plurality of initial humiditys may be obtained at intervals of an initial temperature and an initial humidity, such as an initial temperature and an initial humidity every 5 seconds in 20 seconds.

Referring to FIG. 6, in some embodiments, the number of fans 120 is multiple, and a plurality of fans 120 are used to cooperate to establish an airflow through the air duct 112 to vent the working chamber 111.

In this way, the dehumidification effect of the dishwasher 100 can be achieved to a large extent.

It can be understood that, in order to enhance the dehumidification capability of the working chamber 111, the number of the fans 120 may be plural, that is, the dishwasher 100 includes a plurality of fans 120, so that the plurality of fans 120 can be simultaneously operated to enhance the working chamber 111. The air circulates to carry water vapor from the air out of the dishwasher 100.

It should be noted that a plurality of fans 120 may be disposed inside or outside the dishwasher 100. For example, a fan 120 is disposed outside the dishwasher 100 for drawing air in the working chamber 111, and a fan 120 is disposed at the washing machine. The interior of the bowl 100 is used to direct air into the air duct 112 to cooperate to accelerate air circulation within the working chamber 111.

In some embodiments, when the difference is greater than or equal to 15 degrees Celsius, the first predetermined time is about 170 minutes, the second predetermined time is about 10 minutes; and when the difference is greater than or equal to 10 degrees Celsius and less than 15 degrees Celsius, the first predetermined The time is about 140 minutes, the second predetermined time is about 10 minutes; when the difference is greater than or equal to 7 degrees Celsius and less than 10 degrees Celsius, the first predetermined time is about 110 minutes, and the second predetermined time is about 10 minutes; When the value is equal to 4 degrees Celsius and less than 7 degrees Celsius, the first predetermined time is about 80 minutes, and the second predetermined time is about 10 minutes; when the difference is greater than or equal to 1 degree Celsius and less than 4 degrees Celsius, the first predetermined time is about 40 minutes, The second predetermined time is about 20 minutes; and when the difference is less than 1 degree Celsius, the first predetermined time is about 10 minutes, and the second predetermined time is about 20 minutes.

As such, the operation of the fan 120 can be controlled based on the difference in temperature and dew point temperature.

Specifically, after the dishwasher 100 has been subjected to a drying process, the temperature is generally higher than the dew point temperature. When the difference between the temperature and the dew point temperature is greater than or equal to 15 degrees Celsius, the temperature is much higher than the dew point temperature, and the water vapor in the dishwasher 100 does not substantially condense into water droplets, so the fan 120 can be controlled to stop for about 170 minutes and then run for 10 minutes. When the difference is greater than or equal to 10 degrees Celsius and less than 15 degrees Celsius, the temperature is higher than the dew point temperature, so the fan 120 can be controlled to stop after about 140 minutes and then run for about 10 minutes; when the difference is greater than or equal to 7 degrees Celsius and less than 10 degrees Celsius, The temperature is higher than the dew point temperature, so the fan 120 can be controlled to stop for about 10 minutes and then run for about 10 minutes. When the difference is greater than or equal to 4 degrees Celsius and less than 7 degrees Celsius, the temperature is slightly higher than the dew point temperature, so the fan 120 can be controlled to stop. After about 80 minutes, the operation is about 10 minutes. When the difference is greater than or equal to 1 degree Celsius and less than 4 degrees Celsius, the temperature and the dew point temperature are close to each other. The water vapor in the dishwasher 100 is easily condensed into water droplets, so the fan 120 can be controlled to stop. After about 40 minutes, run for about 20 minutes; when the difference is less than 1 degree Celsius, the temperature is basically low. At the dew point temperature, the water vapor in the dishwasher 100 has substantially condensed into water droplets, so that the fan 120 can be controlled to stop for about 10 minutes and then run for about 20 minutes.

Referring to FIG. 7, a dishwasher 100 according to an embodiment of the present invention includes a housing 110, a fan 120, a temperature detecting unit 130, a humidity detecting unit 140, one or more processors 150, a memory 160, and one or more programs.
