The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "inner", "outer", "axial", "radial", "circumferential", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
An ultrasonic transducer 100 for a cooking appliance according to an embodiment of the present invention is described below with reference to fig. 1 to 12.
Ultrasonic transducers refer to devices for mutual conversion of energy forms, and in the field of acoustics, particularly to devices for converting electric energy into sound energy so as to achieve certain special processes and processing precision. In the industrial field, common ultrasonic transducers are generally applied to instruments such as an ultrasonic bread knife, an ultrasonic cleaning machine, an ultrasonic welding machine, and the like.
However, the power and structural design required for the ultrasonic transducers varies for different modes of action and agents of action. For example, the full power of the large-volume ultrasonic cleaning tank and the ultrasonic plastic welding machine is 300W-1000W, the volume of the ultrasonic transducer is large, the size requirement of the cooking utensil is not met, and the ultrasonic transducer cannot be directly applied to the cooking utensil. For another example, the power of the domestic ultrasonic atomizer, the cleaning machine and the bread knife is between 50W and 200W, the structural design of the ultrasonic transducer cannot meet the requirements of most cooking appliances, for example, for the cooking appliances, the nutrition effect is important, when the ultrasonic transducer is applied to the cooking appliances, the temperature of the working environment is higher, the requirement is severer, and if the ultrasonic transducer of the above-mentioned apparatus is directly applied to the cooking appliances, the problem of too high heat production or too high noise is easy to occur, and the ultrasonic transducer cannot normally work.
Therefore, the present invention provides an ultrasonic transducer 100 for a cooking appliance, and the ultrasonic transducer 100 can satisfy the use requirement of the cooking appliance. Referring to fig. 1 to 12, the power P of the ultrasonic transducer 100 for a cooking appliance according to an embodiment of the present invention satisfies: p is 50 W.ltoreq.300W, and the ultrasonic transducer 100 may include a piezoelectric element 10 for generating ultrasonic waves.
Specifically, the piezoelectric assembly 10 may include a plurality of piezoelectric sheets (e.g., piezoelectric ceramics) 11 and electrode sheets 12, where the plurality of piezoelectric sheets 11 may be stacked, and the electrode sheets 12 may be connected to the piezoelectric sheets 11. When the electrode sheet 12 is electrified, the voltage across the two end faces of the piezoelectric sheet 11 can be changed, and the piezoelectric sheet 11 generates high-frequency vibration under current excitation by utilizing the inverse piezoelectric effect, so that the conversion from electric power to mechanical power is realized, and ultrasonic waves are generated.
In addition, the power capacity of the piezoelectric sheet 11 is G, the thickness of the piezoelectric sheet 11 is L, the area of the piezoelectric sheet 11 is a, the operating frequency of the ultrasonic transducer 100 is fn, and the number N of the piezoelectric sheets 11 can satisfy: n is P/(G × fn × a × L). Therefore, according to the use requirements of the cooking appliances, the piezoelectric sheets 11 of different models and different quantities can be selected, so that the ultrasonic transducer 100 can have different powers P and different structural sizes, and the structure and ultrasonic requirements of different cooking appliances are met. In the working process of the cooking appliance, the ultrasonic transducer 100 achieves the required power capacity, the situation that the input power is too large relative to the transducer elements to generate excessive heat or noise is prevented, and the service life of the ultrasonic transducer 100 is prolonged.
In the cooking process, the ultrasonic transducer 100 vibrates at a high frequency under a specific frequency, and the radiated ultrasonic energy acts on the food material of the cooking appliance, so that the emulsification of the food material and the extraction of nutrient substances can be promoted, the extraction time of nutrient components in the food material and the flavoring time of the food material are reduced, the taste of the food material is better, and the nutritive value is higher. Of course, the ultrasonic transducer 100 can also pretreat the food material before cooking to remove harmful substances such as dirt, pesticide, meat blood and the like in the food material, so that the food material is cleaner and safer, or can ultrasonically clean the cooking utensil after cooking to disperse, loosen and fall off the accumulated scale attached to the wall of the cooking cavity, so that the self-cleaning of the cooking utensil is realized, and the cleaning is easier and cleaner.
According to the utility model discloses a power P for cooking utensil's ultrasonic transducer 100 satisfies 50W and is less than or equal to P and is less than or equal to 300W to ultrasonic transducer 100's parameter satisfies: n is P/(G × fn × a × L). This ultrasonic transducer 100 can satisfy most cooking utensils's user demand, and the nutrition extraction effect of eating the material is better, has strengthened the culinary art effect to it is low to produce the heat in the course of the work, and the noise is low.
The piezoelectric sheet 11 may have different structures according to actual requirements. For example, in some embodiments, the piezoelectric patch 11 may be annular, with an outer diameter of the annulus beingAnnular inner diameter ofIn this case, the area a of the piezoelectric sheet 11 may be
The power capacity G of the piezoelectric sheet 11 is a discrete constant depending on the type and process of the piezoelectric sheet 11, and for example, the power capacity of a lead zirconate titanate emissive ceramic can be up to 6W/(cm)3KHz). And in the utility model discloses in, the power capacity G of piezoelectric patches 11 can satisfy: 2W/(cm)3·KHz)≤G≤3W/(cm3KHz) that the piezoelectric sheet 11 is more consistent with the cooking requirements of the cooking appliance.
According to some embodiments of the present invention, the working frequency fn of the ultrasonic transducer 100 may satisfy: fn is more than or equal to 20KHz and less than or equal to 40 KHz. The sound with the frequency less than 20KHz can be heard by people, if the frequency of the ultrasonic transducer 100 is less than 20KHz, the noise of the ultrasonic transducer 100 is larger, the use feeling of a user is reduced, and the market competitiveness of the cooking utensil and the ultrasonic transducer 100 is not facilitated.
In addition, the axial length of the ultrasonic transducer 100 is inversely proportional to the frequency fn, and when the frequency is too high, the axial length of the ultrasonic transducer 100 is too short, and when the ultrasonic transducer 100 is applied to a cooking appliance, the ultrasonic transducer 100 may not be immersed in food or the depth of the immersed food may be small, which may not meet the use requirements of most cooking appliances.
Therefore, the utility model discloses in, ultrasonic transducer 100's operating frequency fn satisfies 20KHz and is less than or equal to fn and is less than or equal to 40KHz, can satisfy most cooking utensils's user demand to noise at work is low. For example, in some embodiments, the operating frequencies fn of ultrasonic transducer 100 may be 22KHz, 26KHz, 30KHz, 36KHz, 40KHz, etc., respectively.
In some embodiments of the present invention, as shown in fig. 1-12, the ultrasonic transducer 100 may further include: a first end block 20, a second end block 30, and a vibratory rod 40. The first end block 20 and the second end block 30 may be respectively disposed at two axial ends of the piezoelectric assembly 10 to fix the piezoelectric assembly 10, so as to improve the stability of the piezoelectric assembly 10. The vibration rod 40 may be separately manufactured and then coupled to the second end block 30, or the vibration rod 40 and the second end block 30 may be a single piece. The mechanical vibration generated by the piezoelectric module 10 may be transmitted to the vibration bar 40 through the second end block 30, and the vibration bar 40 may emit an ultrasonic wave outward. In some embodiments, the vibrating rod 40 may be an amplitude transformer to change the amplitude of the ultrasonic waves, improve the vibration velocity ratio, and improve the energy transfer efficiency.
Alternatively, as shown in fig. 1, 5 and 9, the ultrasonic transducer 100 may further include a pre-tightening bolt 50, and the pre-tightening bolt 50 may sequentially penetrate through the first end mass 20, the piezoelectric assembly 10, the second end mass 30 and the vibrating rod 40 to achieve axial pre-tightening of the first end mass 20, the piezoelectric assembly 10, the second end mass 30 and the vibrating rod 40, so that the connection structure is simple and firm.
In addition, as shown in fig. 1 to 12, the electrode sheet 12 may include a plurality of electrode sheets 12, a plurality of electrode sheets 12 may be axially spaced by the piezoelectric sheet 11, and the plurality of electrode sheets 12 may be connected in parallel or in series, so that the ultrasonic transducer 100 may output ultrasonic waves of different intensities.
In the present invention, as shown in fig. 2, 6 and 10, the maximum radial dimension of the ultrasonic transducer 100May be larger than the outer diameter of the piezoelectric assembly 10So as to realize the transmission of high-frequency vibration and meet the resonance effect. Optionally, in the present invention, the maximum radial dimension of the ultrasonic transducer 100May be the larger of the maximum radial dimension of the first end mass 20 and the maximum radial dimension of the second end mass 30, or the maximum radial dimension of the ultrasonic transducer 100 when the maximum radial dimension of the first end mass 20 and the maximum radial dimension of the second end mass 30 are equalThe maximum radial dimension of the first end block 20.
Since the piezoelectric module 10 is fixed at both axial ends by the first and second end blocks 20 and 30, the maximum radial dimension of the ultrasonic transducer 100 is obtainedIs larger than the outer diameter of the piezoelectric sheet 11In the process, the action area between at least one of the first end block 20 and the second end block 30 and the piezoelectric component 10 is larger, so that the situation that the stress of the piezoelectric sheet 11 is too concentrated can be prevented, the stress of the piezoelectric sheet 11 is more uniform, the actual power and the actual working frequency are closer to the designed power and frequency, the heat productivity and the working noise are lower, and the service life is longer.
Further, the outer diameter of the piezoelectric sheet 11Maximum radial dimension of ultrasonic transducer 100Can satisfy the following conditions:not only can make the stress of the piezoelectric sheet 11 more uniform, but also can preventThe radial dimension of the first end block 20 or the second end block 30 is too large to interfere with the electrical connection structure (e.g., the terminal pins of the electrode plate 12) of the piezoelectric assembly 10, and the structural design is more reasonable.
