Referring to FIG. 1 to FIG. 3, an embodiment of the present invention provides a smart oven control system. The intelligent dishwasher control system includes a drying machine 100, which is provided with a door opening and closing detecting unit 10, a temperature and humidity detecting unit 20, a dehumidifying unit 30, and a control circuit 40. Each of the above units may be disposed at each predetermined position on the dryer 100 according to actual design requirements. It should be noted that the drying machine 100 illustrated in FIG. 1 and FIG. 2 is a wall-mounted drying machine, but may also be a floor-standing or a drawer-type drying machine. This embodiment does not limit the drying machine 100. The appearance of the dishwashing machine 100 can be used to place dishes such as bowls, plates, etc. to be dried. The door opening and closing detecting unit 10, the temperature and humidity detecting unit 20, the dehumidifying unit 30, and the control circuit 40 of the present embodiment will be further described below. Related structure and actions.

The door opening and closing detection unit 10 is electrically connected to the control circuit 40, and the door opening and closing detection unit 10 is configured to detect the opening and closing of the door panel 101 of the dryer 100, and correspondingly generate an opening and closing signal to the control circuit 40. The door opening and closing detecting unit 10 is preferably, but not limited to, disposed at a lower edge of the adjacent door panel 101. In practical applications, the door opening and closing detection unit 10 can be implemented by a proximity sensor, a light blocking sensor or a micro switch, but is not limited thereto.

The temperature and humidity detecting unit 20 is electrically connected to the control circuit 40, and the temperature and humidity detecting unit 20 is configured to detect the temperature and humidity in the oven 100, and correspondingly generate a temperature signal and a humidity signal to the control circuit 40. The temperature and humidity detecting unit 20 is preferably, but not limited to, disposed within the dryer 100. In a practical application, the temperature and humidity detecting unit 20 may include a temperature sensor and a humidity sensor, but is not limited thereto.

The dehumidifying unit 30 is electrically connected to the control circuit 40, and the dehumidifying unit 30 is configured to perform a dehumidifying operation (or a drying operation). The dehumidification unit 30 is preferably, but not limited to, disposed within the oven 100. In a practical application, the dehumidifying unit 30 may include a hot air blower 31 and an ozone generator 32, but may further include an ultraviolet germicidal lamp, so that the dehumidifying unit 30 can generate hot air for dehumidification while generating ozone for sterilization. It can dry, sterilize or deodorize dishes such as dishes.

The control circuit 40 is electrically connected to the door opening and closing detecting unit 10, the temperature and humidity detecting unit 20, and the dehumidifying unit 30. The control circuit 40 may include, but is not limited to, a control chip (MCU), a microcontroller, or a digital signal processor (DSP) control chip and a driving circuit. The control circuit 40 can determine according to the received opening and closing signal, the temperature signal and the humidity signal, and perform corresponding control on the dehumidifying unit 30, as follows: The control circuit 40 has an automatic detection mode for automatic detection. In the mode, when the control circuit 40 determines that the door panel 101 of the dryer 100 is opened and closed according to the received opening and closing signal, the control circuit 40 controls the temperature and humidity detecting unit 20 to detect the humidity in the dryer, and the control circuit 40 according to reception When the humidity signal reaches that the humidity in the drying machine 100 exceeds the first preset value, the dehumidifying unit 30 is controlled to perform the dehumidifying operation, so that the humidity in the drying machine 100 is reduced below the first preset value. Thereby, through the functions of active detection and active dehumidification, the humidity of the dishwashing machine 100 can be greatly increased after the door panel 101 of the dishwasher 100 is opened and closed a plurality of times, thereby causing the tableware to be wet and to breed bacteria.

Moreover, after the humidity in the dryer 100 drops below the first set value, the control circuit 40 starts to automatically count for a preset time, and when the counting is completed (for example, when the counting expires or counts down to return) When the temperature and humidity detecting unit 20 detects the humidity in the drying machine 100, and the control circuit 40 determines that the humidity in the drying machine 100 exceeds the first preset value according to the humidity signal, the dehumidifying unit 30 is controlled. The dehumidification operation reduces the humidity in the dryer 100 below a first predetermined value. Thereby, the function of the active detection and the active dehumidification after a period of time can prevent the humidity of the dryer 100 from rising after the oven 100 is allowed to stand for a period of time.

In addition, when the control circuit 40 controls the dehumidifying unit 30 to perform the dehumidifying operation, the control circuit 40 can control the hot air blower 31 of the dehumidifying unit 30 to perform continuous or intermittent hot air supply according to the received temperature signal, or the hot air continues to heat up and No, to achieve the efficiency of dehumidification drying.

The dishwasher 100 of the embodiment is further provided with a human machine interface 50. The human interface 50 is electrically connected to the control circuit 40, and the human interface 50 is used to operate the dryer 100. Thereby, the user can give an instruction to the dryer 100 through the human interface 50, and the dryer 100 can report the execution message and the system message to the user through the human interface 50. For example, the human interface 50 can be a touch display screen, which can display temperature and humidity, and can be correspondingly provided with a power switch, an automatic detection mode switch, and a manual detection mode switch, and each of the above The switch can be, for example, a touch switch, a pressure sensitive switch, a capacitive switch, or an electromagnetic switch. Moreover, the power switch is used to turn on or stop the power, and the automatic detection mode switch is used to set the control circuit 40 to In the automatic detection mode, the manual detection mode switch is used to set the control circuit 40 in the manual detection mode. Of course, the control circuit 40 can also have other modes such as manual or standby mode. Therefore, the control circuit 40 can be switched from the automatic detection mode to the manual detection mode through the human interface 50. In the manual detection mode, the control circuit 40 controls the temperature and humidity detection unit 20 to detect the humidity in the dryer 100. When the control circuit 40 determines that the humidity in the dryer 100 exceeds the second preset value according to the humidity signal, the dehumidifying unit 30 is controlled to perform the dehumidifying operation to lower the humidity in the dryer 100 to a second predetermined value or less. It is worth mentioning that the second preset value is smaller than the first preset value, for example, the first preset value has a humidity of 70% RH (relative humidity), and the second preset value has a humidity of 40%. RH, therefore, in the manual detection mode, when the humidity in the dryer 100 reaches 40% RH, the dehumidification operation can be performed, and the dehumidification operation is not forced manually when the humidity does not reach 40% RH. Dehumidification can only be carried out when the humidity must be as high as 70% RH. In this way, the phenomenon of dehumidification operation manually forced to be completely eliminated without drying is eliminated, and the effect of environmental protection and energy saving is achieved.

According to the above embodiment, the present invention can be summarized as a smart oven control method, which is suitable for the intelligent dishwasher control system described in the above embodiments.
