Description

Technical Field

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

[0002] As user demand for refrigeration equipment such as refrigerators increases, the functionality of these devices is also constantly expanding. For example, to meet users' needs for rapid defrosting of frozen food inside the refrigeration equipment, radio frequency (RF) defrosting devices are being installed to quickly defrost frozen food in the refrigerator.

[0003] The radio frequency defrosting device includes a main body and a drawer. The drawer includes a drawer frame for sliding cooperation with the main body and a door for closing the main body's access port. In related technologies, the drawer frame and the door are connected by screws, thus requiring holes to be drilled in the door to install the screws. However, since the radio frequency defrosting device generates a large amount of radiation during operation, drilling holes in the door poses a risk of magnetic leakage. Utility Model Content

[0047] 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 1As 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] The radio frequency defrosting device includes a main body and a drawer. The drawer includes a drawer frame for sliding engagement with the main body and a door for closing the opening of the main body. In related technologies, the drawer frame and the door are connected by screws, thus requiring holes to be drilled in the door to install the screws. However, since the radio frequency defrosting device generates a large amount of radiation during operation, drilling holes in the door poses a risk of magnetic leakage. To mitigate the problems existing in related technologies to some extent, embodiments of this application provide a drawer assembly, a radio frequency defrosting device, and a refrigeration device that can significantly reduce the risk of magnetic leakage.

[0054] This application is described below with reference to the accompanying drawings and specific embodiments:

[0055] Please see Figure 2 and Figure 3 This application provides a drawer assembly 10a for use in the radio frequency defrosting device 10 of a refrigeration device 1. The drawer assembly 10a provided in this application can significantly reduce the risk of magnetic leakage.

[0056] Please see Figures 4-6 In this embodiment, the drawer assembly 10a includes a drawer body 100, a door 200, a mating component 300, and a fastener 400. The drawer body 100 includes a frame 110 and a frame 130. The frame 130 is mounted on the frame 110 and has a receiving cavity for accommodating items. The frame 110 is provided with a positioning structure 120. The mating component 300 is disposed on the side of the door 200 near the frame 110 and mates with the positioning structure 120. The fastener 400 connects the mating component 300 and the frame 110.

[0057] The refrigeration device 1 is roughly rectangular. For ease of description, we define the height direction Z, width direction X, and thickness direction Y. In the operating state of the refrigeration device 1, the vertical direction is the height direction Z, and the projection of the refrigeration device 1 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. It can be understood that the frame 110 is also roughly rectangular, and the height direction Z, width direction X, and thickness direction Y of the frame 110 are consistent with those of the refrigeration device 1.

[0058] The drawer body 100 includes a frame 110 and a frame 130. The frame 130 is used to hold items, and the frame 110 is used to support the frame 130 and slides in cooperation with the main body 10b of the radio frequency defrosting device 10, so that the door 200 can open or close the access port of the main body 10b to realize the retrieval and placement of items. Specifically, the frame 110 includes two first side walls 111, a second side wall 112, and a third side wall 113. The two first side walls 111 are arranged opposite each other along the width direction X, and the second side walls 112 and the third side walls 113 are arranged opposite each other along the thickness direction Y. The two first side walls 111 are used to slide in cooperation with the main body 10b, and the second side wall 112 is used to cooperate with the door 200. The positioning structure 120 can be set on any one of the side walls of the frame 110.

[0059] A mating component 300 is located on the side of the door body 200 near the frame 110 to facilitate mating with the positioning structure 120 on the frame 110. The mating component 300 can be welded to the door body 200. The mating component 300 engages with the positioning structure 120, achieving initial positioning and installation of the mating component 300 on the frame 110. The fastener 400 connects the mating component 300 and the frame 110, ensuring a stable connection between the mating component 300 and the frame 110, thereby allowing the door body 200 to be stably installed on the frame 110. Of course, the mating component 300 and the positioning structure 120 can be detachably mated, and the fastener 400 can be detachably connected to the mating component 300 and the frame 110, thus facilitating the installation and removal of the door body 200 from the frame 110.

[0060] The drawer assembly 10a provided in this application embodiment has a fastener 400 connecting the mating part 300 and the frame 110. That is, the door 200 is connected to the frame 110 through the mating part 300, but the door 200 is not directly connected to the frame 110. Therefore, there is no need to make holes in the door 200, which can greatly improve the situation of magnetic leakage.

[0061] Please see Figure 6 and Figure 7 In some embodiments, the mating part 300 includes an installation part 310 and a mating part 320 arranged at an angle. The installation part 310 is connected to the door body 200, and the mating part 320 is mated with the positioning structure 120.

[0062] The mounting part 310 is connected to the door body 200 so that the mating part 300 is connected to the door body 200. The mounting part 310 has a plate-like structure and can be welded to the door body 200. The mating part 320 is set at an angle to the mounting part 310 so that the mating part 320 is closer to the frame 110, thereby facilitating the mating part 320 to mate with the positioning structure 120. Specifically, the mounting part 310 and the mating part 320 can be set perpendicularly.

[0063] Please see Figure 6 and Figure 7In some embodiments, the positioning structure 120 includes a slot 120a, and the mating part 320 is engaged with the slot 120a.

[0064] The mating part 320 engages with the slot 120a, thus achieving the engagement between the mating part 320 and the positioning structure 120. When installing the door body 200 and the frame 110, the mating part 320 is first engaged with the slot 120a to achieve initial positioning and installation of the door body 200 and the frame 110, ensuring accurate installation of the door body 200. Then, the mating part 320 and the frame 110 are fixedly connected using fasteners 400 to ensure a stable connection between the door body 200 and the frame 110. Since the mating part 320 engages with the positioning structure 120 through a snap-fit ​​mechanism, when the door body 200 needs to be disassembled, the fasteners 400 are first removed, and then the mating part 320 is disengaged from the slot 120a.

[0065] Please see Figure 7 and Figure 8 In some embodiments, there are two slots 120a, which are respectively disposed on two first side walls 111. There are two mating parts 300, which are respectively disposed on both sides of the door body 200. The mating parts 320 of the two mating parts 300 are engaged with the slots 120a on the same side.

[0066] Two first sidewalls 111 are arranged opposite each other along the width direction X. Two mating parts 300 are respectively arranged on both sides of the door body 200 along the width direction X. The two mating parts 300 are correspondingly arranged with the corresponding slots 120a on the same side, and the mating parts 320 of the two mating parts 300 are engaged with the corresponding slots 120a, thereby realizing the mating of the mating parts 300 and the positioning structure 120. Since there are two slots 120a and two mating parts 300, and the two slots 120a are respectively arranged on both sides of the frame 110 along the width direction X, and the two mating parts 300 are respectively arranged on both sides of the door body 200 along the width direction X, the force between the door body 200 and the frame 110 is evenly distributed, and the connection is more stable.

[0067] Of course, in order to facilitate the mating of the mating part 320 and the slot 120a, the slot 120a can be provided on the side of the first side wall 111 near the door body 200.

[0068] Please see Figure 6 and Figure 7 In some embodiments, the slot 120a is provided along the thickness direction Y of the frame 110.

[0069] It is understandable that the first sidewall 111 is arranged along the thickness direction Y, meaning that the first sidewall 111 has sufficient space in the thickness direction Y, so the slot 120a can be arranged along the thickness direction Y. Furthermore, the mating part 320 is also arranged along the thickness direction Y of the frame 110, allowing the mating part 320 to fully engage with the slot 120a. The slot 120a is through in the thickness direction Y, so the mating part 320 can be directly inserted into the slot 120a from the side where the door body 200 is located in the thickness direction Y, facilitating the installation of the door body 200.

[0070] Please see Figures 8-10 In some embodiments, a connecting portion 114 is provided on the first sidewall 111, the connecting portion 114 has a first connecting hole 114a, the mating portion 320 has a second connecting hole 321 at the end away from the door body 200, and the fastener 400 passes through the first connecting hole 114a and the second connecting hole 321.

[0071] The connecting part 114 protrudes from the first side wall 111, and the mating part 320 can extend into a slot 120a in a direction away from the door body 200. The second connecting hole 321 can be provided in the part of the mating part 320 that extends into the slot 120a. Since the connecting part 114 has a first connecting hole 114a and the mating part 320 has a second connecting hole 321, the first connecting hole 114a and the second connecting hole 321 are correspondingly provided. The fastener 400 passes through the first connecting hole 114a and the second connecting hole 321, thereby realizing the fixed connection between the mating part 300 and the frame 110.

[0072] Specifically, both the first connecting hole 114a and the second connecting hole 321 can be threaded holes, and the fastener 400 is a screw. The screw is simultaneously threaded into both the first connecting hole 114a and the second connecting hole 321, thus achieving a fixed connection between the mating part 300 and the frame 110. One, two, or more connecting holes 114 and 321 can be provided; there is no limitation on this. Since the connecting part 114 protrudes from the first sidewall 111, and the first connecting hole 114a is located in the first connecting part 114, it is unnecessary to open a hole in the first sidewall 111, further improving the magnetic leakage situation.

[0073] The mating part 320 may include a base plate 322 and a first side plate 323 and a second side plate 324 disposed opposite to each other on both sides of the base plate 322 along the width direction X. The base plate 322 is disposed at an angle to the first side wall 111. The first side plate 323 contacts the first side wall 111 and has a clearance opening to avoid the connecting part 114. The second connecting hole 321 is disposed on the second side plate 324. The connecting part 114 abuts against the second side plate 324 so that the first connecting hole 114a mates with the second connecting hole 321, thereby facilitating the insertion of the fastener 400.

[0074] Please see Figure 10In some embodiments, the top of the frame 110 is provided with a retaining edge 115, and the two first side walls 111 are provided with guide rail connectors 116, forming a groove 120a between the retaining edge 115 and the guide rail connectors 116.

[0075] Since the two first sidewalls 111 are used for sliding engagement with the main body 10b, the two first sidewalls 111 are provided with guide rail connectors 116, which are used for sliding engagement with the guide rail assembly of the main body 10b. Since the top of the frame 110 is provided with a retaining edge 115, a groove 120a is formed between the retaining edge 115 and the guide rail connector 116. That is, the existing structure of the frame 110 is used to configure the groove 120a, without the need for additional components, thus simplifying the structure of the frame 110.

[0076] Please see Figures 11-13 In some embodiments, the card slot 120a is disposed on the second sidewall 112.

[0077] The second sidewall 112 mates with the door body 200, meaning the second sidewall 112 faces the door body 200 and is in direct contact with it. Since the slot 120a is located on the second sidewall 112, it facilitates the mating part 320 mating with the slot 120a. The slot 120a can be located at the top of the second sidewall 112, and there can be one, two, or more slots 120a spaced apart. The mating part 300 can correspondingly have multiple mating parts 320, each of which engages within its corresponding slot 120a, thereby improving the installation effect of the door body 200 on the frame 110.

[0078] In some embodiments, the card slot 120a is provided along the width direction X of the frame 110.

[0079] It is understandable that the second sidewall 112 is provided along the width direction X, meaning that the second sidewall 112 has sufficient space in the width direction X, so the slot 120a can be provided along the width direction X. Furthermore, the mating part 320 is also provided along the width direction X of the frame 110, so that the mating part 320 is fully engaged with the slot 120a.

[0080] Specifically, please refer to Figure 14 The mating part 320 includes a first mating plate 325 and a second mating plate 326 arranged at an angle. The first mating plate 325 connects the second mating plate 326 and the mounting part 310, and the first mating plate 325 and the mounting part 310 are arranged at an angle. A portion of the second mating plate 326 is engaged with the slot 120a. Specifically, the first mating plate 325 and the second mating plate 326 are arranged perpendicularly, and the first mating plate 325 is arranged perpendicularly to the mounting part 310.

[0081] Please see Figure 15 and Figure 16The slot 120a has an installation opening 121 on one side along the width direction X. The bottom of the slot 120a is open, and the installation opening 121 communicates with the open opening. A snap-fit ​​plate 122 is provided inside the slot 120a, and a snap-fit ​​interface is formed between the snap-fit ​​plate 122 and the second side wall 112. When installing the mating part 300, a portion of the mating part 320 is pushed into the slot 120a along the width direction X through the installation opening 121 until the portion of the mating part 320 is snapped into the snap-fit ​​interface, forming a mating fit. The open opening at the bottom of the slot 120a allows the remaining portion of the mating part 320 to pass through.

[0082] Please see Figure 14 and Figure 17 In some embodiments, the mating part 300 further includes a first overlapping part 327 that is angled to the mounting part 310, and a second overlapping part 117 is provided on the second side wall 112. The first overlapping part 327 and the second overlapping part 117 are overlapped along the height direction Z of the frame 110.

[0083] When the drawer assembly 10a is installed into the main body 10b, the frame 110 will be subjected to a certain torque, which will be transmitted to the fastener 400, causing the fastener 400 to be easily deformed by the force, affecting the connection between the door 200 and the frame 110. In this embodiment, since the first overlapping part 327 and the second overlapping part 117 are overlapped along the height direction Z of the frame 110, when the frame 110 is subjected to torque, the force can be transmitted to the mating part 300 through the first overlapping part 327 and the second overlapping part 117, and then to the door 200, thereby making the drawer assembly 10a more evenly stressed and improving the deformation of the fastener 400.

[0084] Specifically, both the first overlapping portion 327 and the second overlapping portion 117 are plate-like structures. The first overlapping portion 327 is perpendicular to the second sidewall 112, and the second overlapping portion 117 is perpendicular to the mounting portion 310. Both the first overlapping portion 327 and the second overlapping portion 117 are arranged along the width direction X. The first overlapping portion 327 can overlap the top or bottom surface of the second overlapping portion 117. There can be one, two, or more first overlapping portions 327 and second overlapping portions 117, without limitation.

[0085] Please see Figure 14 and Figure 17 In some embodiments, the mating part 300 further includes a fixing part 328 disposed at an angle to the mounting part 310. The fixing part 328 is attached to the bottom surface of the second side wall 112. The fixing part 328 has a first fixing hole 328a, and the bottom surface of the second side wall 112 has a second fixing hole 118. The fastener 400 passes through the first fixing hole 328a and the second fixing hole 118.

[0086] The first fixing hole 328a and the second fixing hole 118 are respectively provided, and the fastener 400 passes through the first fixing hole 328a and the second fixing hole 118, thereby realizing the fixing of the mating part 300 and the frame 110.

[0087] Specifically, the fixing part 328 is arranged perpendicularly to the mounting part 310. The first fixing hole 328a and the second fixing hole 118 can both be screw holes. The fastener 400 is a screw, which is screwed into both the first fixing hole 328a and the second fixing hole 118, thereby fixing the mating part 300 to the frame 110. The fixing part 328 and the second fixing hole 118 can be provided in one, two or more, without limitation.
