Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of knocking response of a steam-bake combination machine, and in particular to a knocking vibration conversion mechanism, a knocking response module and a steam-bake combination machine. Background Art
[0002] The door handle or control panel is used to open and close the door, which requires great force after the steaming and baking mode ends, and has poor intelligence. At the same time, as the current mainstream built-in steam-bake machine, the handle affects the overall integrity, has poor appearance, and takes up extra space.
[0003] With the development of all-in-one steam-bake machines, there has emerged an intelligent all-in-one steam-bake machine that uses knocking as a trigger source. The number of knocks is identified by a pressure sensor, and when the number of knocks reaches a preset value in a short period of time, the door opening action of the all-in-one steam-bake machine is triggered. However, the existing all-in-one steam-bake machine directly installs the pressure sensor for responding to vibration inside the door. The high-frequency vibration generated by knocking on the door body has a short transmission distance in the door body, resulting in a small knocking response range of the all-in-one steam-bake machine. At the same time, considering that the difference between the first peak value and the second peak value of the high-frequency vibration is small, it is necessary to set a higher amplitude response threshold for the pressure sensor to ensure that only one electrical signal is generated after each knock. Since the amplitude of each knock is different, there may be a situation in which the amplitude of one or more knocks during the actual knocking process of the user cannot reach the amplitude response threshold, that is, there is a problem of inconsistency between the actual number of knocks and the number of times reported by the pressure sensor response. These problems all lead to a poor actual user experience. Summary of the invention
[0004] Since the existing steam-bake combination machine equipped with a knock response module has the problems of small knock response range and insensitive knocking, it is necessary to provide a knock vibration conversion mechanism, a knock response module and a steam-bake combination machine.
[0005] The knocking vibration conversion mechanism provided in the present application is used to connect the door body and the pressure sensor of the steam-bake combination machine, including:
[0006] Delay oscillator;
[0007] a spring, the spring being mounted on the time-delay vibrator and being used for transmission connection with the door body; and
[0008] A vibration attenuation component, the vibration attenuation component is installed on the delay vibrator and is used for transmission connection to the pressure sensor;
[0009] The natural vibration frequency of the vibration damping component is greater than the natural vibration frequency of the spring;
[0010] The spring is used to transfer the high-frequency knocking vibration from the door body to the delay vibrator so that the delay vibrator vibrates at a low frequency; the vibration attenuation component is used to transfer the low-frequency vibration from the delay vibrator to the pressure sensor, and absorb the low-frequency vibration energy of the delay vibrator while transferring so that the low-frequency vibration is attenuated.
[0011] With such a configuration, the high-frequency vibration generated by the knocking is captured in time with the help of the spring and transmitted to the delay vibrator, so that the delay vibrator generates low-frequency vibration that can be recognized by the pressure sensor, rather than relying on the door body to directly transmit to the pressure sensor, which solves the problem of short transmission distance of high-frequency vibration and is conducive to expanding the position range of the knocking point on the door body; low-frequency vibration has a longer vibration period than high-frequency vibration, that is, in the same time interval, the number of peaks and valleys of the low-frequency vibration is less than the number of peaks and valleys of the high-frequency vibration, and then the low-frequency vibration is quickly attenuated with the help of the vibration attenuation component to form a unique low-frequency vibration wave. The amplitude of the first peak or trough of the low-frequency vibration is much larger than the amplitude of the subsequent peaks or troughs, which facilitates the lowering of the amplitude response threshold of the pressure sensor. Under the premise that only one electrical signal is generated for each knock, the pressure sensor can also respond to knocking vibrations with lower amplitudes, so that the response value and the actual value of the number of knocks can be matched one by one, which is conducive to improving the user experience.
[0012] In one embodiment, the vibration attenuation component includes a mounting plate and an elastic arm, the two ends of the elastic arm are fixedly connected to the mounting plate and the delay vibrator respectively, the natural vibration frequency of the mounting plate is greater than the natural vibration frequency of the elastic arm, and the elastic coefficient of the elastic arm is greater than the elastic coefficient of the spring.
[0013] With such arrangement, when the energy of the low-frequency vibration is transmitted to the mounting plate through the elastic arm, it will be absorbed by the mounting plate in the form of deformation, thereby accelerating the attenuation rate of the low-frequency vibration. Due to the inconsistency in the elastic coefficient between the elastic arm and the spring, the resonance period of the combined structure of the spring, delay vibrator and elastic arm is relatively long, ensuring that the amplitude of the second resonance point is much smaller than the amplitude of the first resonance point, which is conducive to further lowering the amplitude response threshold of the pressure sensor, thereby improving the response sensitivity of the knocking vibration conversion mechanism to knocking.
[0014] In one embodiment, the elastic arm includes a beam body located between the mounting plate and the delay vibrator, and a first connector and a second connector extending from two ends of the beam body toward the mounting plate and toward the delay vibrator respectively, the first connector is fixedly connected to the mounting plate, and the second connector is fixedly connected to the delay vibrator.
[0015] Such an arrangement is conducive to shortening the distance between the mounting plate and the delay vibrator, thereby shortening the overall size of the knock vibration conversion mechanism and facilitating the arrangement of the knock vibration conversion mechanism in a door body with limited thickness.
[0016] In one embodiment, the first connector has an enlarged head fixedly connected to the mounting plate.
[0017] With such a configuration, the enlarged head can increase the connection strength between the elastic arm and the mounting plate, which helps prevent the pressure sensor from being damaged due to knocking vibrations of excessively high energy.
[0018] In one embodiment, the first connector and the second connector are arc-shaped, and there is a smooth transition between the first connector and the beam body, and between the second connector and the beam body.
[0019] Such arrangement, on the one hand, is conducive to reducing stress concentration at the connection points between the first connector and the second connector and the beam body respectively; on the other hand, when the distance between the delay vibrator and the mounting plate is short, the vibration of the delay vibrator will be decomposed into bending of the elastic arm and its own expansion and contraction after being transmitted to the elastic arm, and its own expansion and contraction will be used to absorb part of the vibration energy, thereby enhancing the effect of the knock response module on the rapid attenuation of the low-frequency vibration.
[0020] In one embodiment, there are multiple elastic arms, which extend from the edge of the mounting plate toward the middle of the mounting plate respectively.
[0021] With such an arrangement, the multiple elastic arms are tightly connected to the delay vibrator, which can ensure the connection strength between the delay vibrator and the mounting plate. In addition, the multiple elastic arms can restrain each other, reducing the degree of freedom of the delay vibrator, thereby accelerating the attenuation speed of the low-frequency vibration.
[0022] In one embodiment, the mounting plate is a cross, and the number of the elastic arms is four and they extend radially from the delay vibrator to four ends of the cross respectively.
[0023] Such an arrangement is conducive to increasing the deformation of the edge of the mounting plate, facilitating the use of a pressure sensor with lower accuracy, thereby reducing production costs.
[0024] In one of the embodiments, the mass of the vibration attenuation component is greater than the mass of the delay vibrator.
[0025] Such an arrangement reduces the natural vibration amplitude of the vibration attenuation component, thereby avoiding interference with the pressure sensor's recognition of normal knocking vibrations.
[0026] This application also provides a tap response module, including:
[0027] Circuit boards;
[0028] As the above-mentioned knocking vibration conversion mechanism, the knocking vibration conversion mechanism is installed on the circuit board;
[0029] a knocking plate, the knocking plate abutting against a spring of the knocking vibration conversion mechanism; and
[0030] A pressure sensor is mounted on the vibration attenuation component of the knocking vibration conversion mechanism and is electrically connected to the circuit board.
[0031] With this arrangement, the vibration of the knocking plate can be sensed by the spring and transmitted to the delay vibrator. The low-frequency vibration of the delayed vibration is attenuated by the vibration attenuation component and then sensed by the pressure sensor to generate a corresponding electrical signal. The circuit board processes the electrical signal to achieve different functions.
[0032] The present application also provides a steam-bake combination machine, including:
[0033] a housing having an inlet;
[0034] A door body, wherein the door body cover is arranged at the entrance;
[0035] As the knock response module mentioned above, the knock response module is installed on the door body; and
[0036] A driving component is installed on the box body and is drivingly connected to the door body, and the knock response module is electrically connected to the driving component.
[0037] With such a configuration, the knock response module provided in the present application can accurately identify the user's multiple knock vibrations, avoid omissions, and enhance the feedback effect when the user knocks, thereby accurately realizing the function of knocking to open the door, which is beneficial to improving the user experience.

[0050] The door handle or control panel is used to open and close the door, which requires great force after the steaming and baking mode ends, and has poor intelligence. At the same time, as the current mainstream built-in steam-bake machine, the handle affects the overall integrity, has poor appearance, and takes up extra space.
[0051] With the development of all-in-one steam-bake machines, an intelligent all-in-one steam-bake machine has emerged that uses knocking as a trigger source. The pressure sensor identifies the number of knocks, and when the number of knocks reaches a preset value in a short period of time, the door opening action of the steam-bake machine is triggered.
[0052] However, the existing steam-bake combination machine directly installs the pressure sensor used to respond to vibrations inside the door, and uses the pressure sensor to directly respond to knocking vibrations. First, the high-frequency vibration generated by knocking on the door body has a short transmission distance in the door body, resulting in a small knocking response range of the steam-bake combination machine; secondly, considering that the difference between the first peak value and the second peak value of the high-frequency vibration is small, it is necessary to set a higher amplitude response threshold for the pressure sensor to ensure that only one electrical signal is generated after each knock. Since the amplitude of each knock is not the same, during the actual knocking process of the user, there may be a situation where the amplitude of one or more knocks cannot reach the amplitude response threshold. In other words, there is a problem of inconsistency between the actual number of knocks and the number of times the pressure sensor responds in actual use. These problems all lead to a poor actual user experience.
[0053] Based on this, it is necessary to provide a knocking vibration conversion mechanism, a knocking response module and a steam-bake machine that can reduce the amplitude response threshold of the pressure sensor.
[0054] See also Figure 1, Figure 1 A schematic diagram of the structure of the knocking vibration conversion mechanism provided in the present application. The knocking vibration conversion mechanism provided in the present application includes a spring 10, a delay vibrator 20 and a vibration attenuation component 30, wherein the spring 10 and the vibration attenuation component 30 are respectively installed on both sides of the delay vibrator 20, and the natural vibration frequency of the vibration attenuation component 30 is greater than the natural vibration frequency of the spring 10; the spring 10 is used to transfer the high-frequency knocking vibration from the door body 80 to the delay vibrator 20, so that the delay vibrator vibrates at a low frequency; the vibration attenuation component 30 is used to transfer the low-frequency vibration from the delay vibrator 20 to the pressure sensor 40, and absorb the low-frequency vibration energy of the delay vibrator 20 while transferring so that the low-frequency vibration is attenuated. In order to solve the problem of the small knock response range of the door body 80, the high-frequency vibration generated by the knock is captured in time by the spring 10, and the high-frequency vibration is converted into a low-frequency vibration that can be recognized by the pressure sensor 40 with the help of the delay vibrator 20, rather than relying on the door body 80 to directly transmit the original high-frequency vibration, which makes up for the short transmission distance of the high-frequency vibration and is conducive to expanding the position range of the knocking point on the door body 80. In order to solve the problem of the inconsistency between the actual number of knocks and the number of knocks responded by the pressure sensor 40, the present application quickly attenuates the low-frequency vibration of the delay vibrator 20 through the vibration attenuation component 30, thereby forming a low-frequency vibration that can be better recognized by the pressure sensor 40. The difference between this easily identifiable low-frequency vibration and the high-frequency vibration is that: within the same attenuation period, the number of peaks or troughs of the low-frequency vibration wave is shorter, and the amplitude of the peaks and troughs is larger. That is to say, the amplitude of the first peak or trough of the low-frequency vibration wave is much greater than the amplitude of the subsequent peaks or troughs. In other words, after lowering the vibration threshold of the existing pressure sensor 40, the pressure sensor 40 can also generate only one electrical signal within a vibration attenuation cycle in the technical solution of the present application, so that it can identify the tapping vibration with weaker tapping force among multiple tappings by the user. Therefore, in actual use, the response value and the actual value of the number of tapping times can correspond one to one, thereby improving the range of tapping response feedback. For users, the sensitivity of tapping feedback is improved, which is conducive to improving the user experience.
[0055] It is understandable that in other embodiments, the spring 10 and the vibration attenuation assembly 30 may also be located on the same side of the delay vibrator 20, as long as the knocking vibration can be guided to be transmitted along the spring 10, the delay vibrator 20 and the vibration attenuation assembly 30 in sequence.
[0056] It is worth noting that the technical solution of the present application does not improve the sensitivity of the pressure sensor 40, but breaks through the limitation of the amplitude response threshold. In fact, the sensitivity of the existing pressure sensor 40 is very high, but when faced with continuous tapping by the user, if the complete tapping vibration curve is recorded and the waveform is recognized by software, it not only requires additional data storage and data processing chips to achieve, which undoubtedly increases the production cost, but also requires a certain amount of data processing time, that is, there is a lag in the tapping response.
[0057] See also Figure 1 Specifically, in one embodiment provided in the present application, the vibration attenuation component 30 includes a mounting plate 31 and an elastic arm 32, the two ends of the elastic arm 32 are fixedly connected to the mounting plate 31 and the delay vibrator 20 respectively, the natural vibration frequency of the mounting plate 31 is greater than the natural vibration frequency of the elastic arm 32, and the elastic coefficient of the elastic arm 32 is less than the elastic coefficient of the spring 10. When the energy of the low-frequency vibration is transmitted to the mounting plate 31 through the elastic arm 32, it will be absorbed by the mounting plate 31 in the form of deformation, thereby achieving rapid attenuation. Due to the inconsistency of the elastic coefficients of the elastic arm 32 and the spring 10, the resonance period of the combined structure of the spring 10, the delay vibrator 20 and the elastic arm 32 is relatively long, ensuring that the amplitude of the second resonance point is much smaller than the amplitude of the first resonance point, which is conducive to further lowering the amplitude response threshold of the pressure sensor 40, thereby improving the response sensitivity of the knocking vibration conversion mechanism to knocking.
[0058] Optionally, in order to achieve miniaturization of the mechanism, in one embodiment provided in the present application, the elastic arm 32 includes a beam body 321 located between the mounting plate 31 and the delay vibrator 20, and a first connector 322 and a second connector 323 extending from both ends of the beam body 321 toward the mounting plate 31 and toward the delay vibrator 20, respectively, the first connector 322 is fixedly connected to the mounting plate 31, and the second connector 323 is fixedly connected to the delay vibrator 20. This is conducive to shortening the distance between the mounting plate 31 and the delay vibrator 20, thereby shortening the overall size of the knock vibration conversion mechanism, and facilitating the arrangement of the knock response mechanism in the door body 80 with limited thickness.
[0059] Furthermore, in order to increase the structural strength of the vibration attenuation assembly 30, the first connector 322 has an enlarged head 3221 fixedly connected to the mounting plate 31, and the enlarged head 3221 can increase the connection strength between the elastic arm 32 and the mounting plate 31, thereby making the vibration attenuation assembly 30 more sturdy and durable, which is beneficial to prevent damage to the pressure sensor 40 caused by excessively high energy impact vibration.
[0060] Furthermore, in an embodiment provided by the present application, the first connector 322 and the second connector 323 are arc-shaped, and there is a smooth transition between the first connector 322 and the beam 321, and between the second connector 323 and the beam 321. This is beneficial to reducing the stress concentration at the connection between the first connector 322 and the second connector 323 and the beam 321, and on the other hand, under the condition that the distance between the delay vibrator 20 and the mounting plate 31 is short, the vibration of the delay vibrator 20 is transmitted to the elastic arm 32 and will be decomposed into the bending of the elastic arm 32 and its own expansion and contraction, and the elastic arm 32 will absorb part of the vibration energy by its own expansion and contraction, thereby accelerating the attenuation speed of the low-frequency vibration.
[0061] Optionally, there are multiple elastic arms 32, and each of them extends from the edge of the mounting plate 31 toward the middle of the mounting plate 31. The multiple elastic arms 32 are tightly connected to the delay vibrator 20, which can ensure the connection strength between the delay vibrator 20 and the mounting plate 31. In addition, the multiple elastic arms 32 can be mutually restrained, reducing the degree of freedom of the delay vibrator 20, thereby improving the attenuation effect of the vibration attenuation component 30 on the low-frequency vibration.
[0062] Furthermore, the mounting plate 31 is a cross, and the number of elastic arms 32 is four and they extend radially from the delay vibrator 20 to the four ends of the cross, respectively. This is conducive to increasing the deformation of the edge of the mounting plate 31, facilitating the use of a pressure sensor 40 with lower precision, thereby reducing production costs.
[0063] Preferably, in an embodiment provided in the present application, the mass of the vibration attenuation component 30 is greater than the mass of the delay vibrator 20. The self-vibration amplitude of the vibration attenuation component 30 is reduced to avoid interfering with the pressure sensor 40 in identifying normal knocking vibrations.
[0064] See also Figure 4 , Figure 4 for Figure 3 The partial enlarged view of the steam-bake combination machine at X is shown. The present application also provides a knock response module, including a circuit board 50, a knock plate 60, a pressure sensor 40 and a knock vibration conversion mechanism as described above, the knock vibration conversion mechanism is installed on the circuit board 50, the knock plate 60 abuts against the spring 10 of the knock vibration conversion mechanism, and the pressure sensor 40 is installed on the vibration attenuation component 30 of the knock vibration conversion mechanism and is electrically connected to the circuit board 50. The vibration of the knock plate 60 can be sensed by the spring 10 and transmitted to the delay vibrator 20, and the low-frequency vibration of the delay vibration can generate a unique low-frequency vibration after passing through the vibration attenuation component 30, which is sensed by the pressure sensor 40, and the pressure sensor 40 generates an electrical signal accordingly, and the circuit board 50 processes the electrical signal to achieve different functions.
[0065] See also Figures 2 to 4 , Figure 2This is a schematic diagram of the structure of the steam-bake combination machine provided in this application. Figure 3 for Figure 2 The present application also provides a steam-bake-in-one machine, comprising a box body 70 with an entrance, a door body 80 covering the entrance, the above-mentioned knock response module and a drive assembly 90, wherein the knock response module is installed on the door body 80, the drive assembly 90 is installed on the box body 70 and is drive-connected to the door body 80, and the knock response module is electrically connected to the drive assembly 90. The knock response module provided in the present application can accurately identify multiple knock vibrations of the user to avoid omissions, and strengthen the feedback effect when the user knocks, thereby accurately realizing the function of knocking to open the door, which is conducive to improving the user experience.
[0066] Optionally, when the mounting plate 31 is a cross, a cross groove matching the shape of the cross can be specifically opened on the door body 80, and the pressure sensor 40 is installed on the inner side of the door body 80 and pressed against the vibration attenuation component 30 of the knocking vibration conversion mechanism.
[0067] See also Figure 4 Optionally, in an embodiment provided in the present application, a circuit board 50 for electrically connecting to the pressure sensor 40 can be integrated into the main control chip board of the entire steam-bake machine. This not only facilitates testing, but also avoids the need to install an additional chip on the door body 80, which increases the thickness of the door body 80, thereby simplifying the structure of the door body 80.
[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0069] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
