Description

Technical Field

[0001] This application belongs to the field of household appliance technology, and in particular relates to a radio frequency defrosting device and a refrigeration equipment. Background Technology

[0002] The radio frequency (RF) defrosting device includes a defrosting chamber and an RF chamber. The defrosting chamber is used to hold food, and the RF chamber is used to mount electrodes. The electrodes can radiate energy into the defrosting chamber, thereby defrosting the food inside. The defrosting chamber and the RF chamber are separated by a partition. However, in related technologies, because the electrodes dissipate heat during operation, the partition is prone to thermal deformation. Utility Model Content

[0007] An electrode plate is disposed within the radio frequency cavity, and along the height direction of the main body, the projection of the electrode plate onto the main body at least partially overlaps with the projection of the heat-resistant component onto the main body.

[0008] The coefficient of thermal expansion of the heat-resistant component is greater than that of the mounting component.

[0009] In the radio frequency defrosting device provided in this application embodiment, since the partition includes a heat-resistant component, and the projection of the electrode plate on the main body and the projection of the heat-resistant component on the main body at least partially overlap along the height direction of the main body, at least part of the heat emitted by the electrode plate can be transferred to the heat-resistant component. Since the thermal expansion coefficient of the heat-resistant component is greater than that of the mounting component, the degree of thermal deformation of the heat-resistant component after being heated is relatively small, thereby improving the overall deformation of the partition.

[0013] In some embodiments, the partition further includes a guide, the mounting port has a mounting side, the guide is disposed on the mounting side, and a plurality of the slots are distributed on each side of the mounting port other than the mounting side.

[0014] In some embodiments, the slot is located on the side of the mounting port near the radio frequency cavity.

[0015] In some embodiments, the back panel of the main body is provided with an air outlet communicating with the radio frequency cavity, the mounting member is connected to the back panel and forms an air outlet duct with the back panel, the air outlet duct communicates the air outlet and the radio frequency cavity, and the side of the mounting member away from the back panel forms a ventilation opening communicating with the defrosting cavity and the radio frequency cavity between it and the main body.

[0037] Please see Figure 1 The radio frequency defrosting device 10 is installed inside the refrigeration equipment to rapidly defrost frozen food within the equipment, thereby meeting the multifunctional needs of the refrigeration equipment. For example... Figure 1 As shown, the radio frequency defrosting device 10 includes a radio frequency generation component 19, which includes a power supply module 19a, a power amplifier module 19c, and a control module 19b. The power supply module 19a, the power amplifier module 19c, and the control module 19b are all electrically connected. The power supply module 19a supplies power to the power amplifier module 19c and the control module 19b. The power amplifier module 19c generates an initial signal at a set frequency. The control module 19b controls the operation of the circuits in the power supply module 19a and the power amplifier module 19c. When it is necessary to adjust the output power of the power amplifier module 19c, the control module 19b calculates a voltage regulation control command based on an internal algorithm and sends it to the power supply module 19a. The power supply module 19a then adjusts the voltage to change its output voltage.

[0038] The power amplifier module 19c includes a signal source 19f, a power amplifier circuit 19e, and a detector circuit 19d. The signal source 19f generates an initial signal at a set frequency (40.68MHz). The power amplifier circuit 19e amplifies the initial signal, increasing its power, and outputs the power amplifier signal. The detector circuit 19d detects the output power of the power amplifier signal and the reflected power, feeding it back to the control module 19b. Alternatively, the power amplifier module 19c can directly use a resonant amplifier to operate within a fixed frequency band and output the power amplifier signal.

[0039] The radio frequency defrosting device 10 also includes a tuning board 15, a tuning inductor 17, and an electrode 16. The tuning inductor 17 and the electrode 16 are electrically connected, and the tuning board 15 is electrically connected to the power amplifier module 19c. After receiving the power amplifier signal, the electrode 16 radiates radio frequency energy to the food to defrost it quickly.

[0040] Specifically, the signal source output module is the source of the radio frequency (RF) signal, capable of outputting a fixed-frequency RF signal. This RF signal is amplified stage by a power amplifier before being output to the load (i.e., the food placed inside the drawer assembly). The RF generation component 19 can detect the RF signal at the load end in real time, detecting the output power and reflected power of the power amplifier signal and feeding this information back to the control module 19b. The control module 19b controls the tuning board 15 and the tuning inductor 17 based on the detection results, working together to achieve optimal impedance matching, maximizing power output to the load, and effectively reducing power reflection in the system.

[0041] Of course, the RF signal output terminal of the RF generator assembly 19 can also be directly connected to the electrode plate 16 via a coaxial cable. The output frequency can be adjusted by the real-time detection and control module 19b of the RF generator assembly 19 to achieve impedance matching and stable power transmission. That is, the control module 19b adjusts the output frequency according to the detection results to achieve the best impedance matching state, so that the power is output to the load as much as possible, preventing power reflection in the system and ensuring stable transmission of RF power.

[0042] The above embodiments are the basic working principle of the radio frequency defrosting device and are only used as a reference for this application. The specific radio frequency circuit composition is not limited to the content described above.

[0043] The radio frequency (RF) defrosting device includes a defrosting chamber and an RF chamber. The defrosting chamber is used to hold food, and the RF chamber is used to mount electrodes. The electrodes can radiate energy into the defrosting chamber, thereby defrosting the food inside. The defrosting chamber and the RF chamber are separated by a partition. However, in related technologies, because the electrodes dissipate heat during operation, the partition is prone to thermal deformation.

[0044] To improve the above-mentioned technical problems to a certain extent, this application provides a radio frequency defrosting device and a refrigeration equipment, which can reduce the degree of thermal deformation of the partition.

[0045] This application is described below with reference to the accompanying drawings and specific embodiments:

[0046] Please see Figures 2-4 This application provides a radio frequency defrosting device 10, which is applied to a refrigeration device 1. The radio frequency defrosting device 10 provided in this application can reduce the degree of thermal deformation of the partition 200.

[0047] Please see Figures 2-4 In this embodiment, the radio frequency defrosting device 10 includes a main body 100, a partition 200, and an electrode 16. The main body 100 has a cavity 110, and the partition 200 is disposed within the cavity 110 to divide the cavity 110 into a defrosting cavity 111 and a radio frequency cavity 112. The partition 200 includes a mounting member 210 and a heat-resistant member 220. The mounting member 210 is connected to the main body 100, and the heat-resistant member 220 is mounted on the mounting member 210. The electrode 16 is disposed within the radio frequency cavity 112. Along the height direction of the main body 100, the projection of the electrode 16 onto the main body 100 at least partially overlaps with the projection of the heat-resistant member 220 onto the main body 100.

[0048] Among them, the coefficient of thermal expansion of the heat-resistant component 220 is less than that of the mounting component 210.

[0049] The refrigeration device 1 is roughly rectangular. For ease of description, the height direction Z, width direction X, and thickness direction Y are defined. In the operating state of the refrigeration device 1, the vertical direction is the height direction Z, and the projection of the main body 100 in the vertical direction is a rectangle. The direction of the longer side is the width direction X, and the direction of the shorter side is the thickness direction Y.

[0050] Similarly, for ease of description, six directions are defined: up, down, left, right, front, and back. In the height direction Z, up is closer to the top surface and down is closer to the bottom surface; in the width direction X, left and right are respectively. In the thickness direction Y, the main body 100 has an opening for engaging with the drawer assembly 300; the direction closer to the opening is front, and the direction further from the opening is back.

[0051] The main body 100 is the basic component of the radio frequency defrosting device 10, providing installation and protection for other components of the radio frequency defrosting device 10. A partition 200 is disposed within the cavity 110 of the main body 100 to divide the cavity 110 into a defrosting cavity 111 and a radio frequency cavity 112, with the radio frequency cavity 112 located below the defrosting cavity 111. The defrosting cavity 111 is used to hold the items to be defrosted. An electrode 16 is installed within the radio frequency cavity 112, radiating radio frequency energy into the defrosting cavity 111 to defrost the items within it.

[0052] The partition 200 is located above the electrode 16. The electrode 16 generates heat during operation, and this heat is transferred to the partition 200. The partition 200 includes a mounting member 210 and a heat-resistant member 220. The mounting member 210 is used to connect to the main body 100 to achieve fixed installation of the partition 200 within the cavity 110. The heat-resistant member 220 is mounted on the mounting member 210 and primarily bears the heat dissipated by the electrode 16. Since the projection of the electrode 16 onto the top / bottom surface of the main body 100 along the height direction Z at least partially overlaps with the projection of the heat-resistant member 220 onto the top / bottom surface of the main body 100, in other words, at least part of the heat-resistant member 220 is located directly above the electrode 16, thus being closest to the electrode 16, allowing the heat from the electrode 16 to be primarily transferred to the heat-resistant member 220.

[0053] The coefficient of thermal expansion is a coefficient that describes how the geometric properties of an object change with temperature under the influence of thermal expansion and contraction. Specifically, it refers to the relative change in length, area, or volume of a material when the temperature increases by 1°C. The smaller the coefficient of thermal expansion, the better the dimensional stability of the material at the same high temperature, and the less deformation it undergoes. The coefficient of thermal expansion of the heat-resistant component 220 is smaller than that of the mounting component 210, meaning that the heat-resistant component 220 and the mounting component 210 are made of different materials, and the heat-resistant component 220 has better thermal stability.

[0054] Since the heat of the electrode plate 16 is mainly transferred to the heat-resistant component 220, and the coefficient of thermal expansion of the heat-resistant component 220 is less than that of the mounting component 210, the heat-resistant component 220 has better thermal stability. Therefore, the heat-resistant component 220 is less deformed after being heated, which can improve the overall deformation of the partition plate 200 after being heated.

[0055] Of course, along the height direction Z, the projection of the electrode plate 16 on the main body 100 and the projection of the heat-resistant component 220 on the main body 100 can completely overlap, that is, the projection of the heat-resistant component 220 on the main body 100 completely covers the projection of the electrode plate 16 on the main body 100, which can further enable the heat of the electrode plate 16 to be mainly transferred to the heat-resistant component 220, thereby further improving the deformation of the partition 200.

[0056] In some embodiments, the heat-resistant component 220 is a heat-resistant glass plate, and the mounting component 210 is a polypropylene plastic component.

[0057] Heat-resistant glass, such as borosilicate heat-resistant glass, has a coefficient of thermal expansion of approximately 3.3 × 10^-6 / ℃. This type of glass with a low coefficient of thermal expansion can withstand rapid temperature changes and has high heat resistance and safety. In contrast, the coefficient of thermal expansion of polypropylene plastic is approximately 10 × 10^-5 / ℃, and its heat resistance is relatively weak.

[0058] The heat-resistant component 220 is made of heat-resistant glass plate to mainly bear the heat dissipated by the electrode plate 16. Since the heat-resistant glass has a low coefficient of thermal expansion, the heat-resistant component 220 deforms less after being heated, thereby improving the overall deformation of the partition plate 200 after being heated.

[0059] The main body 100 is made of metal to achieve electromagnetic shielding, while the mounting component 210 is made of polypropylene plastic, which facilitates connection with the main body 100 and enables the partition 200 to be installed on the main body 100. Furthermore, since heat-resistant glass is expensive, using polypropylene plastic for the mounting component 210, which does not primarily bear heat, also reduces costs.

[0060] Please see Figure 5 and Figure 6 In some embodiments, the mounting member 210 is provided with a mounting opening 211, and the heat-resistant member 220 is detachably installed in the mounting opening 211.

[0061] The mounting port 211 passes through the mounting component 210, and the heat-resistant component 220 is installed inside the mounting port 211. That is, the heat-resistant component 220 is connected to the mounting component 210 and exposed inside the mounting port 211. Along the height direction Z of the main body 100, the mounting component 210 and the heat-resistant component 220 basically do not overlap, so that the heat of the electrode plate 16 is transferred to the heat-resistant component 220 as much as possible, reducing the heat of the mounting component 210, thereby further improving the overall deformation of the partition plate 200 after being heated.

[0062] Since the heat-resistant component 220 is detachably installed in the mounting port 211, it is convenient to install and replace the heat-resistant component 220. That is, if the heat-resistant component 220 deforms after long-term use and needs to be replaced, it can be replaced simply by removing the heat-resistant component 220 from the mounting component 210, without having to remove the entire partition 200.

[0063] In some embodiments, the mounting element 210 is circumferentially disposed around the heat-resistant element 220.

[0064] Mounting member 210 may be approximately annular, and it is connected to the rear, left, and right side walls of the main body 100 to enhance the connection stability between the mounting member 210 and the main body 100. Since the main body 100 is approximately rectangular, the mounting member 210 is approximately rectangular annular, and the internal space of the mounting member 210 is the mounting opening 211. The mounting opening 211 is approximately located in the middle of the mounting member 210, and thus the heat-resistant component 220 is also located in the middle of the mounting member 210.

[0065] The electrode plate 16 is generally located at the center of the radio frequency cavity 112. Since the heat-resistant component 220 is located in the middle of the mounting component 210, it can be positioned directly opposite the electrode plate 16 in the height direction Z, allowing the heat-resistant component 220 to primarily bear the heat dissipated by the electrode plate 16. Furthermore, since the heat from the electrode plate 16 dissipates from multiple angles, the projection of the heat-resistant component 220 onto the main body 100 in the height direction Z must be greater than the projection of the electrode plate 16 onto the main body 100. That is, the projection of the heat-resistant component 220 onto the main body 100 completely covers the projection of the electrode plate 16 onto the main body 100 and extends outwards, further ensuring that the heat dissipated by the electrode plate 16 is transferred to the heat-resistant component 220, reducing the deformation of the partition plate 200.

[0066] Since the projection of the heat-resistant component 220 onto the main body 100 needs to be larger than the projection of the electrode plate 16 onto the main body 100, the area ratio of the heat-resistant component 220 in the partition 200 also needs to be relatively large. Specifically, the area ratio of the heat-resistant component 220 in the partition 200 can be 50% to 80%.

[0067] Please see Figures 5-7 In some embodiments, the mounting port 211 has multiple slots 212, which are spaced apart, and the heat-resistant component 220 is snapped into the multiple slots 212.

[0068] The opening of the slot 212 faces the center of the mounting opening 211. The mounting opening 211 has multiple slots 212, meaning the mounting component 210 has multiple slots 212, and at least a portion of each slot 212 is located within the mounting opening 211. The heat-resistant component 220 is engaged within these slots 212, allowing the heat-resistant component 220 to be detachably mounted on the mounting opening 211. When it is necessary to remove the heat-resistant component 220, it can be detached from the slots 212. The spaced arrangement of the multiple slots 212 ensures even stress distribution on the heat-resistant component 220, resulting in more stable installation.

[0069] Please see Figures 7-9 In some embodiments, the partition 200 further includes a guide 230, the mounting port 211 has a mounting side 213, the guide 230 is disposed on the mounting side 213, and a plurality of slots 212 are distributed on each side of the mounting port 211 other than the mounting side 213.

[0070] The mounting port 211 has multiple sides, one of which is configured as a mounting side 213. When the heat-resistant component 220 is installed onto the mounting component 210, the heat-resistant component 220 can slide from the mounting side 213 into the mounting port 211 and engage with each of the slots 212.

[0071] Since the partition 200 also includes a guide 230, and the guide 230 is disposed on the mounting side 213, the guide 230 can provide guidance for the sliding of the heat-resistant component 220, so that the heat-resistant component 220 can be accurately inserted into each slot 212. Since the multiple slots 212 are distributed on each side of the mounting opening 211 except for the mounting side 213, that is, the mounting side 213 is not provided with slots 212, the slots 212 will not interfere with the sliding of the heat-resistant component 220.

[0072] Specifically, the heat-resistant component 220 is rectangular, and the mounting opening 211 is also rectangular. The mounting opening 211 has four sides, one of which is configured as the mounting side 213, and the slots 212 are distributed on the remaining three sides. Each slot 212 may have a protrusion 212a on its side wall, and the heat-resistant component 220 abuts against the protrusion 212a to enhance the snap-fit ​​strength between the heat-resistant component 220 and the slot 212, thereby making the heat-resistant component 220 mounting component 210 more stable.

[0073] The guide member 230 includes a first guide portion 231 and two second guide portions 232. The two second guide portions 232 are respectively disposed on both sides of the mounting side 213. The first guide portion 231 is disposed in the middle of the mounting side 213. The first guide portion 231 has a first guide slope 231a, and the second guide portions 232 have second guide slopes 232a. The first guide slope 231a is used to introduce the heat-resistant component 220 into the mounting port 211. The two second guide slopes 232a are arranged opposite each other to center the heat-resistant component 220, so that the heat-resistant component 220 is accurately inserted into each slot 212. Furthermore, the second guide portion 232 may also be provided with slots 212.

[0074] Please see Figure 10 In some embodiments, the card slot 212 is located on the side of the mounting port 211 near the radio frequency cavity 112.

[0075] The main body 100 has an opening for communicating with the defrosting chamber 111. The opening is used to cooperate with the drawer assembly 300, which can hold items to be defrosted. The electrode plate 16 radiates energy into the defrosting chamber 111, thereby defrosting the items inside the drawer assembly 300. The drawer assembly 300 needs to slide with the defrosting chamber 111. Therefore, the slot 212 is located on the side of the mounting opening 211 near the radio frequency cavity 112, thereby avoiding interference between the drawer assembly 300 and the slot 212 during sliding.

[0076] Please see Figure 4In some embodiments, the back panel of the main body 100 is provided with an air outlet 120 communicating with the radio frequency cavity 112. The mounting member 210 is connected to the back panel and forms an air outlet 214 with the back panel. The air outlet 214 communicates the air outlet 120 and the radio frequency cavity 112. The side of the mounting member 210 away from the back panel forms a ventilation opening 215 communicating with the defrosting cavity 111 and the radio frequency cavity 112 between it and the main body 100.

[0077] The main body 100 has an air inlet 130 that communicates with the defrosting chamber 111. The air inlet 130 is used to communicate with the main air duct of the refrigeration equipment 1, so that the gas (cold air) of the main air duct can enter the defrosting chamber 111 through the air inlet 130 to achieve the microcrystalline preservation function. Since the side of the mounting member 210 away from the back plate forms a vent 215 between it and the main body 100, which communicates the defrosting chamber 111 and the radio frequency chamber 112, the gas will also enter the radio frequency chamber 112 from the defrosting chamber 111 through the vent 215 to dissipate heat from the electrode plate 16. Since the mounting member 210 is connected to the back plate and forms an air outlet 214 with the back plate, and the air outlet 214 communicates with the air outlet 120 and the radio frequency chamber 112, the gas will then enter the air outlet 214 from the radio frequency chamber 112 and finally be discharged from the air outlet 120, realizing the circulation of gas in the chamber 110.

[0078] The mounting component 210 not only serves as a connecting component of the partition 200 to separate the defrosting chamber 111 and the radio frequency chamber 112, but also forms a vent 215 and an air outlet 214 between itself and the main body 100, allowing gas to flow in the radio frequency chamber 112 to dissipate heat from the electrode plate 16. This achieves two goals at once, reduces the number of components, and simplifies the structure of the radio frequency defrosting device 10.

[0079] Furthermore, since the heat-resistant component 220 in this embodiment is a heat-resistant glass plate, the odor generated when heated is small, thereby minimizing the risk of odor being carried into the defrosting chamber 111 during the circulation of gas within the cavity 110, which could affect the food.

[0080] Please see Figure 6 In some embodiments, the radio frequency defrosting device 10 further includes a guide rail assembly 400 and a drawer assembly 300, the drawer assembly 300 being slidably engaged with the guide rail assembly 400, the guide rail assembly 400 being disposed on the mounting member 210.

[0081] The drawer assembly 300 and the guide rail assembly 400 are slidably engaged, allowing the drawer assembly 300 to open or close the opening of the main body 100 by sliding. This sliding engagement between the drawer assembly 300 and the guide rail assembly 400 is existing technology, and its specific structure and principle will not be elaborated here. Since the guide rail assembly 400 is mounted on the mounting member 210, which also serves as the mounting structure for the guide rail assembly 400, the number of components is further reduced, simplifying the structure of the radio frequency defrosting device 10. Specifically, the guide rail assembly 400 and the mounting member 210 can be injection molded.

[0082] Of course, there are two guide rail assemblies 400, which are respectively located on both sides of the mounting member 210 along the width direction X, and the drawer assembly 300 slides with the guide rail assembly 400 on the same side.

[0083] Based on the same inventive concept, please refer to Figure 2 This application also provides a refrigeration device 1, including a cabinet 20 and above, and a radio frequency defrosting device 10. The radio frequency defrosting device 10 is disposed inside the cabinet 20. The refrigeration device 1 can be a refrigerator. The beneficial effects of the refrigeration device 1 provided in this application are the same as those of the radio frequency defrosting device 10 described above, and will not be repeated here.
