Example one

As shown in fig. 1 to 6, an automatic door opener mounting structure with a knock module includes: the base is arranged on the household appliance box body and comprises a shell (such as a box-shaped shell) extending along one direction, and a movement space for the push rod of the automatic door opener to move is formed on the base. In one embodiment, the base extends along the moving direction of the push rod of the automatic door opener to form a rectangular housing, i.e. a moving space for the push rod of the automatic door opener 100 to move. The bottom of the base is fixed on the household appliance box body through a fixing structure or is partially embedded in the household appliance box body. The fixing structure is common fixing structures in the field such as a clamping structure and a screw joint structure, and the embedded mounting structure is also common fixing structures in the field such as a clamping structure and a screw joint structure. In one embodiment, the household appliance is a refrigerator, a microwave oven, or the like. The base part is embedded into the refrigerator body but does not influence the normal movement of the push rod, the size of the automatic door opening device displayed on the household appliance body is reduced through the layout mode, and the user impression is improved. The main control board 13 is configured on the base and deviates from the side of the household appliance box body, and the main control board is integrated with or electrically connected with a knocking module 20. The main control board 13 is mounted on the base, and in some embodiments, the size, shape and contour of the base are set according to the size, shape and contour of the main control board, so that the base and the main control board form a consistent integral structure. The mounting structure further comprises a knocking module 20, the knocking module 20 is mounted on the base, and the main control board 13 is integrated with or connected with the knocking module 20 through a signal line. When the knocking module 20 is integrated with the main control board 13, the installation structure can be simplified, and the space can be saved to reduce the size of the entire automatic door opening device. When the knocking module 20 is separately provided from the main control board 13, it is convenient to maintain the knocking module.

The knocking module 20 is electrically connected with the main control panel 13 arranged in the automatic door opener, so that whether a user performs knocking action on the household appliance or not can be identified, and the refrigerator is instructed to respond according to knocking operation of the user. For example, the refrigerator door is opened by a knocking action of the user, and the refrigerator is turned on for illumination.

The tapping module 20 includes a tapping sensor that receives vibrations generated by a user tapping the appliance. The knocking module 20 further comprises a control unit electrically connected with the knocking sensor, the control unit can be directly arranged on a main control board in the automatic door opening device or independently arranged to receive vibration information transmitted by the knocking sensor and judge whether the vibration information is preset knocking vibration, and if the vibration information is preset knocking vibration, an instruction is sent to enable the refrigerator door body to respond; if the vibration is not the preset knocking vibration, the refrigerator door body does not respond.

After the household appliance is knocked, the knocking module 20 acquires a knocking signal and transmits the knocking signal to the main control board 13 so as to configure the automatic door opening device to execute a door opening action. In some embodiments, the push rod of the automatic door opening device can be configured to move towards the household appliance door body. Since the knocking module 20 is disposed on the box body, a user can trigger the knocking module 20 by knocking the household appliance box body; in addition, because the push rod initially contradicts on the household electrical appliances door body, initial state push rod contact door body but the contact force is unlikely to push open the door body promptly, at this moment, after knocking the household electrical appliances door body, the power of knocking passes through the household electrical appliances door body and transmits to the push rod, triggers the module of knocking 20 in the base through the push rod.

The main control board 13 obtains the current pressure value of the pressure sensor after receiving the instruction to execute the automatic door opening action, if the current pressure is 0, the household appliance door body is opened, and the pressure is not 0 and is not opened. At this time, the obtained initial pressure value may be used to verify whether the initial position of the output jack shaft is proper, and if the initial pressure applied to the output jack shaft 16 reaches a value, it is prompted that the position of the output jack shaft 16 needs to be adjusted. The value specifically refers to the force with which the household appliance door body can be disengaged from the magnetic seal.

The main control board 13 provides a current with a specific value for the solenoid, and the household appliance door body is ejected out by the output top shaft 16 in the solenoid according to the electromagnetic effect. A thrust of a certain strength is generated in view of the current of a certain value. In one embodiment, when the output top shaft 16 includes a pressure sensor (not shown), after the electromagnetic induction module is triggered to start by acquiring the automatic door opening signal, the pressure sensor can sense the door opening force of the output top shaft 16 so as to know the magnitude of the door opening force of the automatic door opener, and when the door opening force is greater than 65N, the magnitude of the current is prompted to change; or the automatic door opening device is prompted to be out of order and needs to be detected and maintained. And when the door opening force is less than or equal to 65N, the automatic door opening device normally operates. In a preferred embodiment, the opening force is preferably 50N to ensure that the automatic door opener will not damage the equipment when a hard object is in front of the door during the activation process. The magnitude of the door opening force can be realized by controlling the magnitude of the current.

In one embodiment, a position sensor and a pressure sensor are included. A position sensor is arranged on the base, and a blocking piece matched with the position sensor is arranged on the output top shaft 16; the one end of output apical axis 16 is close to the end of the household electrical appliances door body promptly and still includes pressure sensor, pressure sensor is used for instructing the initial pressure that the output apical axis received, and when initial pressure surpassed a numerical value after, the suggestion user in time maintains or adjusts the initial position of output apical axis. The numerical value specifically refers to the force that the household appliance door body cannot be separated from the magnetic seal. The position sensor is used for indicating whether the blocking piece of the output top shaft reaches a specified position. The indicating position is used for indicating whether the household appliance door body is opened or not, namely the household appliance door body is opened by the output top shaft 16 when the output top shaft 16 reaches the indicating position.
