Description

Technical Field

[0001] The present invention relates to the technical field of machine learning, and particularly relates to a wax motor control method, a wax motor, and an automatic door. Background Art

[0002] A wax motor is a driving device, which consists of a positive temperature coefficient thermistor (PTC), and the positive temperature coefficient thermistor is installed on a sealed container filled with solid wax. When the solid wax is heated by the energized thermistor to a controllable temperature, the solid wax melts and expands, thereby driving a spring-loaded piston outward. This piston may pull or push the load inward, depending on the orientation of the container in the wax motor housing and the configuration of the spring. When the thermistor is de-energized, the liquid wax cools, and the spring returns the piston to its initial position. Wax motors can be applied to home appliances such as electric steam ovens, exhaust fans, electric ovens, washing machines, or dishwashers. With the improvement of the drying standard requirements in the national standard for dishwashers, a wax motor can be added to the dishwasher to achieve automatic door opening, so as to improve the drying efficiency of the dishwasher.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0043] Figure 1 Schematic diagram of the wax motor structure provided by an embodiment of the present invention. The wax motor includes: a thermistor 101, a wax motor 102, a helical spring 103, and a transmission rod 104. The thermistor 101 is arranged on the wax motor 102. The wax motor 102 includes wax and a probe. The transmission rod 104 is used to connect to an opening device to drive the opening device to open the door structure connected to the opening device.

[0044] Taking the opening of an automatic door as an example, the wax motor is connected to the door opening device, and the door opening device is connected to the door structure. The wax motor provides driving force for the door opening device to drive the door opening device to open the door structure. In the specific implementation process, when the wax motor starts, the thermistor 101 is energized and heated. The wax inside the wax motor 102 expands due to heat, causing the probe inside the wax motor to move outward, pushing the transmission rod 104 to move outward to drive the door opening device to open the door structure. After the wax cools down, the spiral spring 103 can return the transmission rod 104 to its original position.

[0045] It can be seen that during this process, the longer the energization time of the thermistor 101, the larger the stroke parameter of the transmission rod 104 moving outward. That is to say, whether the door structure can be opened in place is related to the energization time of the thermistor 101. When the energization time is long enough, the larger the stroke parameter of the transmission rod 104 moving outward, the door structure can be opened in place. In the prior art, in order to ensure that the door structure can be opened in place, the energization time of the thermistor 101 of the wax motor is usually set to the maximum energization time of the wax motor. However, if the wax motor reaches its maximum energization time every time, it can indeed open the door from a design perspective, but this will cause the heating time of the wax motor to be too long, affecting the service life of the wax motor. Moreover, the door structure always needs to wait for the maximum energization time to open for the next operation, which is time-consuming and not conducive to improving work efficiency. Based on this, the embodiment of the present invention provides a method for controlling a wax motor to improve the door opening efficiency.

[0046] In this embodiment, a wax motor drive model is trained through different types of door structures, and the energization time of the wax motor is controlled through this wax motor drive model. In this embodiment, a reasonable energization time is used to heat the wax and drive the door structure. Compared with using the maximum energization time each time, the service life of the wax motor is extended, and the door structure can be opened in time, improving the door opening efficiency.

[0047] The technical solution of the present invention will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0048] Figure 2 The flowchart of training the wax motor drive model provided by another embodiment of the present invention. As Figure 2 shown, the method includes:

[0049] 201. Obtain a sample set to be trained; the sample set includes at least one type of door structure, and each type includes at least one door structure.

[0050] The execution subject of this embodiment can be the control board of the wax motor. Specifically, it can be a processor provided on the control board.

[0051] In this embodiment, the type of the door body structure is determined by parameters such as the weight, size, door lock structure, and material of the door body structure. If the parameters of two door body structures are the same, they belong to the same type of door body structure.

[0052] In practical applications, different types of door body structures will result in different forming times required for the door body to open in place, and thus different energization times of the thermistor of the wax motor. Therefore, in this embodiment, different types of door body structures can be trained separately. A training set is constructed for each type, and each training set includes multiple samples. That is, the sample set is divided into multiple training sets.

[0053] Specifically, according to the type information of each door body structure, the door body structures with the same type information in the sample set are divided into the same training set, and multiple training sets are obtained.

[0054] 202. For each door body structure in the sample set, obtain the type information of the door body structure, the corresponding pressure signal of the spring, and the stroke parameter of the wax motor; according to the type information of the door body structure, the pressure signal, and the stroke parameter, train the wax motor drive model to be trained to obtain the wax motor drive model.

[0055] Optionally, the training sets divided according to the type information of the door body structure can be trained separately. For each door body structure in each training set, obtain the pressure signal of the spring corresponding to the door body structure and the stroke parameter of the wax motor, and train the wax motor drive model to be trained according to the type information of the door body structure, the pressure signal, and the forming parameter. After completing the training of each sample in each training set, the wax motor drive model is obtained. The wax motor can drive and open different types of door body structures with different energization times under the control of the processor including the wax motor drive model, so that the door body structure can be opened in place in a shorter time. Compared with driving the door body structure with the maximum energization time of the wax motor, the opening efficiency can be improved, and the service life of the wax motor can be extended.

[0056] In this embodiment, the pressure signal of the spring can be obtained by a pressure sensor. Optionally, the spring is provided with a pressure sensor, and obtaining the pressure signal of the spring corresponding to the door body structure includes:

[0057] Obtain the pressure signal of the spring during the door opening process of the door body structure through the pressure sensor.

[0058] Specifically, the pressure sensor is arranged on the spring or at both ends of the spring, as long as it can sense the pressure exerted on the spring.

[0059] Optionally, there are multiple ways to collect the pressure signal. It can be continuously collected or periodically and discretely collected.

[0060] For example, starting from the wax motor, the pressure signal of the spring can be collected at a period T. During the entire door opening process, the sequentially collected pressure signals gradually increase, indicating that the door body is in the process of opening. When the pressure signal changes instantaneously, that is, when the pressure signal suddenly becomes smaller during the sudden growth process, it means that the door body is opened in place. This instantaneous change can be understood as a jump in the pressure signal, and the jump moment corresponds to the moment when the door body is opened in place.

[0061] The confirmation of this jump moment can be judged according to the slope of the curve fitted by the collected pressure signals. When the change value of the slope is greater than the preset threshold, it is determined as the moment when the pressure signal jumps.

[0062] In this embodiment, the stroke parameter of the wax motor refers to the distance that the transmission rod of the wax motor moves outward, that is, the distance that the transmission rod pushes the door opening device to move. The acquisition of this stroke parameter can be obtained by using a distance sensor. Optionally, the wax motor is provided with a distance sensor. The acquisition of the stroke parameter of the wax motor corresponding to the door body structure includes:

[0063] Obtaining the stroke parameter of the wax motor when the pressure signal jumps through the distance sensor.

[0064] Specifically, the distance sensor can be arranged between the wax motor and the door opening device to sense the distance between the door opening device and the wax motor, that is, the distance that the transmission rod of the wax motor pushes outward.

[0065] Figure 3 It is a schematic structural diagram of an automatic door provided by another embodiment of the present invention. The following combines Figure 3 to illustrate the entire training process by way of example, such as Figure 3As shown in the figure, the automatic door includes a wax motor 31, a door opening device 32, and a door body structure (not shown). The wax motor 31 includes a thermistor (not shown) disposed inside the housing, a wax motor 311, a spiral spring 312 for returning the transmission rod 313 to its original position, and a transmission rod 313. The door opening device 32 includes a push rod 321 and a spring 323 disposed inside the housing at one end of the push rod 321 away from the contact with the door body structure. When training the wax motor drive model, for each door body structure, it is necessary to obtain the distance parameter of the wax motor corresponding to the door body structure and the pressure signal of the spring. Therefore, a pressure sensor 322 can be provided on the spring 323, and a distance sensor 314 can be provided outside the housing of the wax motor. The distance sensor can sense the distance between the door opening device 32 and the wax motor, that is, the moving distance X of the transmission rod 313 of the wax motor. Point A is the initial position of the end of the push rod 321 (the distance from the top surface of the housing of the door opening device is H). Under the push of the transmission rod 313 and the spring 323, the push rod and the transmission rod move the same stroke X. Both the pressure sensor 322 and the distance sensor 314 are connected to the processor that controls the wax motor, and respectively send the obtained pressure signal and distance signal to the processor. To train the wax motor drive model set in the processor.

[0066] In the specific implementation process, when the wax motor is started, the thermistor starts to heat up, the wax in the wax motor 311 expands due to heat, and pushes the transmission rod 313 to move outward. Under the push of the transmission rod 313, the spring 323 is squeezed and pushes the push rod 321 to move outward, and the push rod 321 pushes the door body structure to open. During this process, the pressure sensor 322 obtains the force condition of the spring. Optionally, periodic sampling can be performed to obtain discrete pressure sampling values. The processor receives the pressure sampling values and monitors the pressure jump moment. When it is detected that the slope of the curve fitted by the pressure sampling values changes, it is determined that this moment is the jump moment. At this time, the stroke parameter obtained by the distance sensor 314 is recorded. For the door body structure of this sample, the wax motor drive model is trained using this pressure signal and stroke parameter. Multiple samples of the same type are used to train the wax motor drive model, so that the wax motor drive model can output the stroke parameter corresponding to the door body structure of this type, and then obtain the appropriate energization time according to this stroke parameter to shorten the door opening time and extend the service life of the wax motor.

[0067] In this embodiment, by obtaining the type information, pressure signal, and stroke parameter of each door body structure sample, and training a wax motor drive model according to the type information, pressure signal, and stroke parameter, the wax motor drive model can, according to the type of the door body structure, give a stroke parameter that can open the door body structure in place, so as to improve the door opening efficiency and extend the service life of the wax motor.

[0068] Figure 4Schematic flow chart of the wax motor control method provided by another embodiment of the present invention. As Figure 4 shown, the wax motor is connected to the door opening device, and the door opening device includes a spring for pushing the door structure. The method includes:

[0069] 401. Obtain the type information of the door structure.

[0070] The execution subject of this embodiment may be the processor of the wax motor.

[0071] 402. Input the type information into the wax motor driving model to obtain the stroke parameter corresponding to the type of the door structure; the wax motor driving model is trained according to the pressure signals of the springs corresponding to different types of door structures and the stroke parameters of the wax motor.

[0072] In this embodiment, the training process of the wax motor driving model may refer to the specific description of the embodiment shown in Figure 2 and will not be elaborated here.

[0073] In practical applications, after inputting the type information of the door structure to be driven by the wax motor into the wax motor driving model, the trained wax motor driving model can give the stroke parameter corresponding to the type information according to the type information of the door structure. The stroke parameter is the stroke parameter of the wax motor when the door structure of this type is opened in place. Furthermore, the wax motor can be controlled according to the stroke parameter so that the wax motor reaches the stroke parameter to make the door structure open in place. It avoids the shortening of the service life of the wax motor caused by controlling the wax motor to open the door structure with the longest power-on time.

[0074] 403. Start the wax motor according to the stroke parameter so that the wax motor drives the door to open.

[0075] Optionally, the starting the wax motor according to the stroke parameter so that the wax motor drives the door to open includes:

[0076] Determine the power-on time of the wax motor according to the stroke parameter;

[0077] Input the power-on time into the wax motor so that the wax motor drives the door to open with the power-on time.

[0078] Specifically, the determining the power-on time of the wax motor according to the stroke parameter includes:

[0079] Obtain the actual power-on time required for the wax motor to complete the stroke parameter according to the stroke parameter;

[0080] Sum the actual power-on time and the reserved power-on time to obtain the power-on time of the wax motor.

[0081] In practical applications, after the training of the wax motor drive model is completed, the stroke parameters corresponding to different types of door structures can be obtained. Furthermore, the corresponding actual power-on time can be determined based on these stroke parameters. To ensure that the door structure can be fully opened and avoid being in a critical state of being either open or not open, a reserved power-on time can be added to the actual power-on time. During the reserved power-on time, the pressure signal of the pressure sensor is sampled simultaneously. If the obtained pressure sampling value is within the pressure range (this pressure range is the range of pressure changes during the opening process of the door structure from the start of the wax motor to the door being fully opened. This pressure range can be obtained by recording during the training process), then continue heating until the wax motor reaches its maximum stroke. If the obtained pressure sampling value is less than the above pressure range, it indicates that the door structure has been fully opened. The reserved power-on time can be determined through multiple experiments.

[0082] The wax motor control method provided in this embodiment obtains the type information of the door structure, inputs the type information into the wax motor drive model to obtain the stroke parameters corresponding to the type of the door structure. The wax motor drive model is trained based on the pressure signals of the springs corresponding to different types of door structures and the stroke parameters of the wax motor. The wax motor is started according to the stroke parameters to drive the door to open. The wax motor drive model obtained through training can identify different types of door structures and obtain the corresponding stroke parameters, realizing the adaptation to different types of door structures, enabling the wax motor to use a reasonable power-on time for wax heating and driving the door structure. Compared with using the maximum power-on time each time, the service life of the wax motor is extended, and the door structure can be opened in time, improving the door opening efficiency.
