Description

Technical Field

[0001] The present invention relates to the technical field of knock response of a steam-bake combination machine, and in particular to a knock vibration conversion mechanism, a knock 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 a lot of force after the steaming and baking mode ends. It has poor intelligence. At the same time, as the current mainstream built-in steam-bake combination machine, the handle affects the overall integrity, has a poor appearance, and takes up extra space.

[0003] With the development of all-in-one steam ovens, a smart steam oven that uses knocking as a trigger source has emerged. The machine uses a pressure sensor to identify the number of knocks, and when the number of knocks reaches a preset value within a short period of time, the door of the steam oven is triggered to open. However, existing steam ovens install the pressure sensor used to respond to vibrations directly inside the door. The high-frequency vibrations generated by knocking on the door body have a short transmission distance in the door body, resulting in a small knock response range for the steam oven. At the same time, considering the small difference between the first peak and the second peak of the high-frequency vibration, a higher amplitude response threshold needs to be set for the pressure sensor to ensure that only one electrical signal is generated after each knock. Since the amplitude of each knock is different, during the actual knocking process of the user, the amplitude of one or more knocks may fail to reach the amplitude response threshold. In other words, there is a problem of inconsistency between the actual number of knocks and the number 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 this application is used to connect the door body and 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 connected to the door body in a transmission manner; and

[0008] a vibration attenuation component, the vibration attenuation component being mounted on the time-delay vibrator and being connected to the pressure sensor in a transmission manner;

[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 it to attenuate the low-frequency vibration.

[0011] With this arrangement, 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 transmit it directly to the pressure sensor. This 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, within 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 of the number of knocks can correspond to the actual value one by one, which is conducive to improving the user experience.

[0012] In one embodiment, the vibration attenuation assembly 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 this arrangement, the energy of the low-frequency vibration will be absorbed by the mounting plate in the form of deformation when it is transmitted to the mounting plate through the elastic arm, 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 longer, 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 both 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 knocking vibration conversion mechanism and facilitating the arrangement of the knocking 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 damage to the pressure sensor caused by 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 a setting, on the one hand, is conducive to reducing the stress concentration at the connection between the first connector, 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 the 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 improving 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, each extending from an edge of the mounting plate toward a middle portion of the mounting plate.

[0021] With this 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 form mutual restraint, 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 oscillator 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 precision, and thus reducing production costs.

[0024] In one embodiment, the mass of the vibration attenuation component is greater than the mass of the delay vibrator.

[0025] This arrangement reduces the natural vibration amplitude of the vibration attenuation component, 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 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] This 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 driven and connected to the door body, and the knock response module is electrically connected to the driving component.

[0037] With such a setting, the knock response module provided in this 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 conducive to improving the user experience.

[0050] The door handle or control panel is used to open and close the door, which requires a lot of force after the steaming and baking mode ends. It has poor intelligence. At the same time, as the current mainstream built-in steam-bake combination machine, the handle affects the overall integrity, has a poor appearance, and takes up extra space.

[0051] With the development of steam-bake combination machines, a smart steam-bake combination machine has emerged that uses knocking as a trigger source. The pressure sensor identifies the number of knocks and triggers the door opening action of the steam-bake combination machine when the number of knocks reaches a preset value in a short period of time.

[0052] However, existing steam-bake-in-one machines install the pressure sensor used to respond to vibrations directly inside the door, using the pressure sensor to directly respond to knocking vibrations. First, the high-frequency vibrations generated by knocking on the door body have a short transmission distance in the door body, resulting in a small knocking response range for the steam-bake-in-one machine; second, considering that the difference between the first peak and the second peak 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, during the actual knocking process of the user, the amplitude of one or more knocks may not reach the amplitude response threshold. In other words, in actual use, there is a problem of inconsistency between the actual number of knocks and the number of times the pressure sensor responds. 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 combination machine that can reduce the amplitude response threshold of the pressure sensor.

[0054] See also Figure 1, Figure 1 This is a schematic diagram of the structure of the knocking vibration conversion mechanism provided by the present application. The knocking vibration conversion mechanism provided by 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 it to attenuate the low-frequency vibration. In order to solve the problem of the small response range of the knocking on the door body 80, the high-frequency vibration generated by the knocking is captured in time by the spring 10, and the high-frequency vibration is converted into a low-frequency vibration that can be identified 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. This 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 inconsistency between the actual number of knocks and the number of knocks responded by the pressure sensor 40, the present application uses the vibration attenuation component 30 to quickly attenuate the low-frequency vibration of the delay vibrator 20, thereby forming a low-frequency vibration that can be better identified by the pressure sensor 40. The difference between this easy-to-identify 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 amplitudes of the peaks and troughs are larger. That is, 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, thereby being able to identify the weaker tapping vibrations among the user's multiple taps. Therefore, in actual use, the response value and the actual value of the number of taps can correspond one-to-one, thereby increasing the range of the tapping response feedback. For the user, the sensitivity of the 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 in sequence along the spring 10, the delay vibrator 20 and the vibration attenuation assembly 30.

[0056] It is worth noting that the technical solution of this application does not improve the sensitivity of the pressure sensor 40, but rather overcomes the limitation of the amplitude response threshold. In fact, the existing pressure sensor 40 has a high sensitivity, but when faced with continuous tapping by the user, if the method of recording the complete tapping vibration curve and then using software to identify the waveform not only requires the addition of data storage and data processing chips, which undoubtedly increases production costs, 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 assembly 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 in 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 longer, 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, to achieve miniaturization of the mechanism, in one embodiment provided herein, the elastic arm 32 includes a beam 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 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 helps to shorten 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, which has a 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. The enlarged head 3221 can increase the connection strength between the elastic arm 32 and the mounting plate 31, 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 one embodiment provided herein, 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 helps reduce stress concentration at the connections between the first connector 322 and the second connector 323 and the beam 321, and also helps reduce stress concentration at the connections between the first connector 322 and the second connector 323 and the beam 321. Furthermore, when the distance between the time-delay vibrator 20 and the mounting plate 31 is short, the vibration of the time-delay vibrator 20, after being transmitted to the elastic arm 32, is decomposed into the bending of the elastic arm 32 and its own expansion and contraction. The elastic arm 32 utilizes its own expansion and contraction to absorb some of the vibration energy, thereby accelerating the attenuation of the low-frequency vibration.

[0061] Optionally, there are multiple elastic arms 32, each extending from an 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, ensuring the connection strength between the delay vibrator 20 and the mounting plate 31. In addition, the multiple elastic arms 32 can form mutual restraint, reducing the degrees of freedom of the delay vibrator 20, thereby improving the attenuation effect of the vibration attenuation assembly 30 on the low-frequency vibration.

[0062] Furthermore, the mounting plate 31 is shaped like a cross, and the number of elastic arms 32 is four, extending radially from the delay vibrator 20 to the four ends of the cross. This helps to increase the deformation of the edge of the mounting plate 31, facilitates the use of lower-precision pressure sensors 40, and thus reduces production costs.

[0063] Preferably, in one embodiment provided herein, the mass of the vibration damping component 30 is greater than the mass of the delay vibrator 20. This reduces the natural vibration amplitude of the vibration damping component 30 and avoids interfering with the pressure sensor 40's recognition of 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 the knock vibration conversion mechanism as described above. The knock vibration conversion mechanism is mounted 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 mounted 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. The low-frequency vibration of the delayed vibration generates a unique low-frequency vibration after passing through the vibration attenuation component 30, which is sensed by the pressure sensor 40. The pressure sensor 40 generates an electrical signal accordingly, and the circuit board 50 processes the electrical signal to achieve different functions.

The present application also provides a steam-bake combination machine, comprising a box body 70 having an entrance and 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 driven and 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 the user's multiple knock vibrations to avoid omissions, enhance 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 one embodiment provided in the present application, the 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 combination 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 and simplifies the structure of the door body 80.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
