Description

Technical Field

[0001] This application relates to the field of high-pressure defrosting devices, and in particular to a high-pressure electrostatic field defrosting device. Background Technology

[0002] High-voltage electrostatic field defrosting, a novel food defrosting method, works by applying a high voltage to two electrode plates, creating a high-voltage electrostatic field between them. Under the influence of this electric field, particles between the plates move, forming an ion wind, or corona wind. These charged particles generate turbulence and vortices on the food surface, accelerating heat exchange between the food and the environment, thus speeding up the defrosting process.

[0003] To thaw food more quickly, electrode plates are typically equipped with conductive needles. However, the sharp tips of these needles can easily injure food and users, posing a significant safety hazard. Utility Model Content

[0004] Therefore, it is necessary to provide a high-voltage electrostatic field defrosting device to solve the problem that the sharp tip of the conductive needle can easily injure food and users, posing a significant safety hazard.

[0005] A high-voltage electrostatic field defrosting device includes a first electrode plate, a second electrode plate, a conductive needle, and a protective cover. One end of the conductive needle is connected to the first electrode plate, and the other end is suspended. Both the first electrode plate and the conductive needle are installed inside the protective cover, and the protective cover has a through hole corresponding to the suspended end of the conductive needle. The end of the protective cover with the through hole is spaced apart from the second electrode plate along a predetermined direction a, and a receiving space is formed between the protective cover and the second electrode plate to receive the item to be defrosted. When the first electrode plate and the second electrode plate are energized, a high-voltage electrostatic field can be generated in the receiving space.

[0006] In one embodiment, the high-voltage electrostatic field defrosting device includes a housing, a second electrode plate and a protective cover, both located inside the housing, and the distance between the second electrode plate and the protective cover along a preset direction a is configured to be adjustable.

[0007] In one embodiment, the high-voltage electrostatic field defrosting device further includes a drive mechanism. The housing has a first wall and a second wall that are arranged opposite to each other along a preset direction a. The second electrode plate is connected to the first wall. The protective cover is movably connected to the second wall through the drive mechanism, and the drive mechanism can drive the protective cover to move toward or away from the second electrode plate.

[0008] In one embodiment, the high-voltage electrostatic field defrosting device further includes a control module connected to a drive mechanism. The protective cover has an initial position abutting against the second wall, an intermediate position abutting against the surface of the item to be defrosted, and a working position located between the initial position and the intermediate position along a preset direction a. The control module is used to control the drive mechanism to drive the protective cover to move from the initial position to the intermediate position and then from the intermediate position to the working position. The first electrode plate and the second electrode plate are configured to generate a high-voltage electrostatic field when the protective cover is in the working position.

[0009] In one embodiment, the high-voltage electrostatic field defrosting device further includes a high-voltage electric field module, with the first electrode plate and the second electrode plate respectively connected to the positive and negative electrodes of the high-voltage electric field module; the distance between the middle position and the working position along the preset direction a is positively correlated with the voltage of the high-voltage electric field module.

[0010] In one embodiment, the drive mechanism is configured as an electric actuator, and a protective cover is connected to the output shaft of the electric actuator.

[0011] In one embodiment, the protective cover includes an upper housing and a lower housing, which are detachably connected and enclose a cavity, wherein the first electrode plate and the conductive needle are both located within the cavity.

[0012] In one embodiment, the end of the first electrode plate opposite to the conductive needle is fixedly connected to the upper housing, and the through hole is opened in the lower housing.

[0013] In one embodiment, the inner and / or outer walls of the protective cover are provided with an insulating layer.

[0014] In one embodiment, the second electrode plate is used to place the item to be thawed, and the second electrode plate is configured as an aluminum alloy.

[0015] Compared with existing technologies, the high-voltage electrostatic field defrosting device provided in this application houses both the first electrode plate and the conductive needle within a protective cover. This protective cover prevents the suspended end of the conductive needle from scratching the item to be defrosted or the user; in other words, it protects the item from being scratched by the needle tip, thus improving the safety of the high-voltage electrostatic field defrosting device. Furthermore, by providing a through hole on the protective cover corresponding to the suspended end of the conductive needle, the protective cover prevents interference with the high-voltage electrostatic field generated between the conductive needle and the second electrode plate, thereby ensuring a better defrosting effect on the item.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figures 1 to 2 This application provides a high-voltage electrostatic field defrosting device 100, which includes a first electrode plate 110, a second electrode plate 120, a conductive needle 111, and a protective cover 130. One end of the conductive needle 111 is connected to the first electrode plate 110, and the other end is suspended. The first electrode plate 110 and the conductive needle 111 are both installed inside the protective cover 130, and the protective cover 130 has a through hole 137 corresponding to the suspended end of the conductive needle 111. The end of the protective cover 130 with the through hole 137 is spaced apart from the second electrode plate 120 along a preset direction a, and a receiving space 140 is formed between the protective cover 130 and the second electrode plate 120. The receiving space 140 is used to receive the item 200 to be defrosted. When the first electrode plate 110 and the second electrode plate 120 are energized, a high-voltage electrostatic field can be generated in the receiving space 140.

[0028] It is understandable that by installing both the first electrode plate 110 and the conductive needle 111 inside the protective cover 130, the protective cover 130 can prevent the suspended end of the conductive needle 111 from scratching the item 200 to be thawed or the user. In other words, the protective cover 130 can protect the item 200 to be thawed or the user from being scratched by the tip of the conductive needle 111, thereby improving the safety of using the high-voltage electrostatic field defrosting device 100. Furthermore, by providing a through hole 137 on the protective cover 130 corresponding to the suspended end of the conductive needle 111, the protective cover 130 can prevent interference with the high-voltage electrostatic field generated between the conductive needle 111 and the second electrode plate 120, thereby helping to ensure the defrosting effect of the item 200 to be thawed.

[0029] Specifically, multiple conductive pins 111 are configured, and these pins 111 are arranged at intervals on the first electrode plate 110. Multiple through holes 137 are also configured, and each through hole 137 corresponds one-to-one with a conductive pin 111. The suspended end of a conductive pin 111 can be spaced apart from its corresponding through hole 137, or it can partially extend into the through hole 137. The only requirement is that the suspended end of the conductive pin 111 does not protrude from its corresponding through hole 137 outside the protective cover 130.

[0030] Alternatively, in one embodiment, as Figure 2 As shown, the protective cover 130 includes an upper housing 134 and a lower housing 135. The upper housing 134 and the lower housing 135 are detachably connected and form a cavity 136. The first electrode plate 110 and the conductive needle 111 are both located within the cavity 136. This facilitates the installation of the first electrode plate 110 and the conductive needle 111 within the protective cover 130. The upper housing 134 and the lower housing 135 can be connected by snap-fit ​​or screws.

[0031] Furthermore, the lower housing 135 is positioned relative to the upper housing 134 and close to the second electrode plate 120 along a predetermined direction a. The end of the first electrode plate 110 facing away from the conductive pin 111 is fixedly connected to the upper housing 134. Specifically, the first electrode plate 110 can be snapped or fixedly connected to the upper housing 134 by screws. A through hole 137 is formed in the lower housing 135. Specifically, the through hole 137 can be configured as a circular hole, an elliptical hole, or a polygonal hole.

[0032] In one embodiment, the inner wall of the protective cover 130 is provided with an insulating layer; or, in one embodiment, the outer wall of the protective cover 130 is provided with an insulating layer; or, in one embodiment, both the inner and outer walls of the protective cover 130 are provided with insulating layers. Thus, the protective cover 130 can shield the first electrode plate 110, thereby concentrating and controlling the high-voltage electrostatic field between the through hole 137 of the protective cover 130 and the second electrode plate 120, thereby preventing the first electrode plate 110 from interfering with surrounding components.

[0033] Alternatively, the insulating layer can be configured as an organic polymer coating or an inorganic ceramic-based coating. To further enhance the shielding capability of the protective cover 130, the protective cover 130 can also be configured as a plastic structure.

[0034] like Figure 1 As shown, the high-voltage electrostatic field defrosting device 100 also includes a high-voltage electric field module 170. The first electrode plate 110 and the second electrode plate 120 are respectively connected to the positive and negative terminals of the high-voltage electric field module 170 via wiring harnesses. The high-voltage electric field module 170 is used to generate high voltage, thereby generating a high-voltage electrostatic field within the accommodating space 140 when the first electrode plate 110 and the second electrode plate 120 are energized.

[0035] The high-voltage electrostatic field defrosting device includes a housing 150, a second electrode plate 120 and a protective cover 130, all located inside the housing 150. The distance between the second electrode plate 120 and the protective cover 130 along a preset direction a is adjustable.

[0036] Understandably, when the voltage of the high-voltage electric field module 170 remains constant, the distance between the first electrode plate 110 and the second electrode plate 120 along the preset direction a affects the defrosting speed of the item 200 to be defrosted. Specifically, if the distance between the first electrode plate 110 and the second electrode plate 120 along the preset direction a is too large, the defrosting speed of the item 200 to be defrosted will be slow; if the distance between the first electrode plate 110 and the second electrode plate 120 along the preset direction a is too small, the air between the first electrode plate 110 and the second electrode plate 120 is easily broken down, causing a short circuit and posing a risk of equipment damage and safety. By setting the distance between the second electrode plate 120 and the protective cover 130 along the preset direction a to be adjustable, that is, the distance between the first electrode plate 110 and the second electrode plate 120 along the preset direction a is adjustable. This allows the spacing between the first electrode plate 110 and the second electrode plate 120 along a preset direction a to be adjusted according to the different sizes of the items to be thawed 200, so as to ensure efficient thawing of the items to be thawed 200 and ensure safe and reliable operation of the equipment.

[0037] Furthermore, the high-voltage electrostatic field defrosting device also includes a drive mechanism 160. The housing 150 has a first wall 151 and a second wall 152 arranged opposite each other along a preset direction a. The second electrode plate 120 is connected to the first wall 151, and the protective cover 130 is movably connected to the second wall 152 through the drive mechanism 160. The drive mechanism 160 can drive the protective cover 130 to move towards or away from the second electrode plate 120. Thus, when the drive mechanism 160 drives the protective cover 130 to move towards the second electrode plate 120, the distance between the first electrode plate 110 and the second electrode plate 120 along the preset direction a decreases; when the drive mechanism 160 drives the protective cover 130 to move away from the second electrode plate 120, the distance between the first electrode plate 110 and the second electrode plate 120 along the preset direction a increases.

[0038] In one embodiment, such as Figure 4 As shown, the preset direction 'a' is configured along the height of the housing 150. The first wall 151 is located below the second wall 152 along the height of the housing 150, and the second electrode plate 120 is placed on the first wall 151. Thus, the second electrode plate 120 can be used to place the item 200 to be thawed, and it facilitates the installation and removal of the second electrode plate 120 within the housing 150, thereby making it convenient for cleaning and replacement.

[0039] Optionally, the second electrode plate 120 is configured as an aluminum alloy. In this way, the second electrode plate 120 can not only generate a high voltage electrostatic field in conjunction with the first electrode plate 110 and the conductive needle 111, but the second electrode plate 120 made of aluminum alloy itself has excellent thermal conductivity, thereby accelerating the defrosting speed.

[0040] Please see Figures 1 to 4The high-voltage electrostatic field defrosting device 100 also includes a control module (not shown), which is connected to the drive mechanism 160. The protective cover 130 has an initial position 131 that is abutted against the second wall 152, an intermediate position 132 that abuts against the surface of the item 200 to be defrosted, and a working position 133 located between the initial position 131 and the intermediate position 132 along a preset direction a. The control module is used to control the drive mechanism 160 to drive the protective cover 130 to move from the initial position 131 to the intermediate position 132, and then from the intermediate position 132 to the working position 133. The first electrode plate 110 and the second electrode plate 120 are configured to generate a high-voltage electrostatic field when the protective cover 130 is in the working position 133. It is understandable that by setting up a control module, the high-voltage electrostatic field defrosting device 100 can determine the corresponding middle position 132 of the protective cover 130 according to the different volumes of the items 200 to be defrosted, and further automatically adjust it to the corresponding working position 133, so as to ensure that when the first electrode plate 110 and the second electrode plate 120 are discharging, the first electrode plate 110 has a certain distance from the surface of the item 200 to be defrosted, rather than directly contacting the surface of the item 200 to be defrosted.

[0041] Furthermore, the distance between the intermediate position 132 and the working position 133 along the preset direction a is positively correlated with the voltage of the high-voltage electric field module 170. In other words, the higher the voltage of the high-voltage electric field module 170, the larger the distance between the intermediate position 132 and the working position 133 along the preset direction a. That is, the distance between the first electrode plate 110 and the second electrode plate 120 during working discharge is larger, so as to avoid a short circuit accident caused by a large voltage of the high-voltage electric field module 170 but a small distance between the first electrode plate 110 and the second electrode plate 120. Conversely, the lower the voltage of the high-voltage electric field module 170, the smaller the distance between the intermediate position 132 and the working position 133 along the preset direction a. That is, the smaller the distance between the first electrode plate 110 and the second electrode plate 120 during working discharge, so as to avoid a problem that affects the defrosting speed by a large distance between the first electrode plate 110 and the second electrode plate 120 when the voltage of the high-voltage electric field module 170 is low. This ensures that the distance between the first electrode plate 110 and the second electrode plate 120 during operation and discharge matches the voltage of the high-voltage electric field module 170.

[0042] In one embodiment, the drive mechanism 160 is configured as an electric push rod, and the protective cover 130 is connected to the output shaft of the electric push rod. Thus, when the output shaft of the electric push rod extends or retracts, it can drive the protective cover 130 to move along a preset direction a toward or away from the second electrode plate 120. Specifically, the output shaft of the electric push rod is fixedly connected to the upper housing 134.

[0043] The high-voltage electrostatic field defrosting device 100 provided in this application operates as follows: After the user places the item 200 to be defrosted on the second electrode plate 120, the control module controls the electric push rod to extend, pushing the protective cover 130 from the initial position 131 towards the direction closer to the second electrode plate 120, until the protective cover 130 touches the surface of the item 200 to be defrosted, that is, the protective cover 130 moves to the middle position 132. At this time, the resistance of the electric push rod moving downward increases, thereby triggering the control module to control the electric push rod to retract, so as to drive the protective cover 130 towards the direction away from the second electrode plate 120, until the protective cover 130 moves to the working position 133. Afterwards, the high-voltage electric field module 170 generates high voltage, and a high-voltage electrostatic field is generated between the conductive needle 111 and the second electrode plate 120, generating ion wind, which accelerates the defrosting of the item 200.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0045] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
