Description
Technical Field
[0001] This utility model relates to the field of compressor technology, specifically to a protective structure for a control device used in driving a refrigeration and cold storage variable frequency compressor. Background Technology
[0002] As people's living standards improve, consumers have higher requirements for the performance and user experience of refrigeration and freezing equipment. They hope that refrigerators, freezers, and other equipment can be more energy-efficient, quieter, and have better preservation effects. The emergence of variable frequency compressors perfectly meets these needs, and has therefore received widespread attention and welcome from the market. This has prompted manufacturers to increase their research and development and application of variable frequency compressor technology. In the fierce market competition, manufacturers need to continuously launch products with differentiated advantages to attract consumers. As an advanced technology, variable frequency compressors have become an important means for enterprises to enhance product competitiveness. By adopting variable frequency compressors, manufacturers can create more high-end, energy-saving, and intelligent refrigeration and freezing products, thereby standing out in the market.
[0003] In the current technology, refrigerators and freezers are the most common devices in the home environment that use variable frequency compressors for freezing and refrigeration. Protective shells can be installed on the back or bottom of the refrigerator or freezer, close to the compressor, to protect the control device. During use, existing protective devices usually do not have cushioning measures, which can easily cause damage to the internal components of the control device due to vibration. In addition, existing protective devices cannot achieve better heat dissipation, resulting in poor heat dissipation for the control device.
[0004] Therefore, a protective structure for the control device used in driving a variable frequency compressor for refrigeration and cold storage is proposed. Utility Model Content

[0011] Preferably, a crash plate is fixedly installed on one side of the locking block, and push rods are fixedly installed at equal intervals on both sides of the surface of the crash plate. An extrusion plate is fixedly installed at the other end of the push rod. The crash plate can be buffered by the cooperation between the limiting slide, the buffer spring, the connecting concave block, and the locking block. The crash plate can be buffered a second time by the cooperation between the base plate, the foam, the push rod, and the extrusion plate. The locking block can be fixed and disassembled by the knob and the threaded positioning rod, thereby achieving the effect of protection and buffering.
[0012] Preferably, the ventilation adjustment component specifically includes: a ventilation port, which is opened on the top of the protective frame; a controller, which is fixedly installed on one side of the top of the protective frame; a temperature sensor, which is fixedly installed on the top of the inner wall of the protective frame; an L-shaped limiting plate, which is fixedly installed at equal intervals on the top of the inner wall of the protective frame; and a grooved side block, which is fixedly installed at equal intervals on the top of the inner wall of the protective frame.

[0014] This utility model provides a protective structure for the control device used in driving a variable frequency compressor for refrigeration and cold storage. It has the following beneficial effects:
[0015] (1) This utility model provides protection and buffer by setting up a protective buffer component.

[0016] (2) This utility model achieves better ventilation and protection by setting up a ventilation adjustment component. After the temperature sensor detects that the temperature reaches the set threshold, it sends the information to the controller. The controller energizes the electromagnet and then attracts the magnet. The reset spring is compressed, which increases the gap between the two connecting frames, allowing more gas to enter. When not working, the electromagnet is de-energized to achieve automatic shutdown and prevent dust from entering, thereby achieving the effect of ventilation adjustment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example
[0024] A preferred embodiment of the protective structure for the control device driving a variable frequency compressor for refrigeration and cold storage provided by this utility model is, for example... Figure 1-4 As shown: A protective structure for a control device used to drive a refrigeration and cooling inverter compressor includes a mounting frame 1. The surface of the mounting frame 1 is provided with screw holes, and screws 2 are threaded onto the inner wall of the screw holes. A protective frame 3 is fixedly connected to the surface of the mounting frame 1. A protective buffer component 4 is provided on the surface of the protective frame 3, and an air exchange regulating component 5 is provided on the inner wall surface of the protective frame 3.
[0025] The protective buffer assembly 4 specifically includes: a base plate 411, which is fixedly installed on both sides of the inner wall of the protective frame 3; foam 412, which is fixedly installed on the surface of the base plate 411; a limiting sleeve 413, which is fixedly installed on both sides of the protective frame 3; and a knob 4112, which is located on the other side of the limiting sleeve 413.
[0026] The other side of the limiting sleeve 413 is connected to a sliding groove 414. The inner wall of the limiting sleeve 413 is slidably connected to a connecting recess 415. One side of the connecting recess 415 is connected to a threaded hole 416. A buffer spring 417 is fixedly installed at equal intervals on the back of the connecting recess 415. The other end of the buffer spring 417 is fixedly connected to one side of the inner wall of the limiting sleeve 413.
[0027] The inner wall surface of the connecting recess 415 is provided with a locking groove 418, and a locking block 419 is engaged between the inner walls of the locking groove 418. The surface of the locking block 419 is provided with a positioning hole 4111.
[0028] A threaded positioning rod 4113 is fixedly installed on one side of the knob 4112. The other end of the threaded positioning rod 4113 passes through the interior of the slide groove 414, the interior of the threaded hole 416, and the interior of the connecting recess 415 and extends to the interior of the positioning hole 4111 to engage. The outer wall of the threaded positioning rod 4113 is threadedly connected to the inner wall of the threaded hole 416.
[0029] A crash plate 4114 is fixedly installed on one side of the block 419. Push rods 4115 are fixedly installed at equal intervals on both sides of the surface of the crash plate 4114. A pressing plate 4116 is fixedly installed on the other end of the push rod 4115.
[0030] In this example, the protective buffer component 4 is set up for protection and buffering. When the protective plate 4114 is impacted, the buffer spring 417 is compressed and buffered by the locking block 419 and the connecting concave block 415. When the impact force is too large, the foam 412 is squeezed and buffered by the push rod 4115 and the squeezing plate 4116, thereby achieving the function of protection and buffering. Example
[0031] Based on Embodiment 1, a preferred embodiment of the protective structure for the control device of a refrigeration and cold storage inverter compressor drive provided by this utility model is as follows: Figure 1-4 As shown: The ventilation adjustment component 5 specifically includes: a ventilation port 511, which is opened on the top of the protective frame 3; a controller 512, which is fixedly installed on one side of the top of the protective frame 3; a temperature sensor 513, which is fixedly installed on the top of the inner wall of the protective frame 3; an L-shaped limiting plate 514, which is fixedly installed at equal intervals on the top of the inner wall of the protective frame 3; and a grooved side block 518, which is fixedly installed at equal intervals on the top of the inner wall of the protective frame 3.
[0032] The surface of the L-shaped limiting plate 514 is equidistantly connected to a connecting frame 515. A filter screen 516 is fixedly installed between the inner walls of the connecting frame 515. An adsorption magnet 517 is fixedly installed on one side of the connecting frame 515. Electromagnets 519 are fixedly installed on the inner walls of the groove side block 518. A reset spring 5111 is fixedly installed at equal intervals on one side of the groove side block 518. The other end of the reset spring 5111 is fixedly connected to one side of the connecting frame 515.
[0033] In this example, better ventilation and protection are achieved by setting the ventilation regulation component 5. After the temperature sensor 513 detects that the temperature has reached the set threshold, it sends the information to the controller 512. The controller 512 energizes the electromagnet 519, which then attracts the adsorption magnet 517. The reset spring 5111 is compressed, which increases the gap between the two connecting frames 515, allowing more gas to enter, thereby achieving the function of ventilation regulation.
[0034] Working principle: First, the protective buffer assembly 4 provides protection and buffering. When the anti-collision plate 4114 is impacted, the buffer spring 417 is compressed and buffered by the locking block 419 and connecting recess 415, causing the threaded positioning rod 4113 to slide in the slide groove 414. When the impact force is too large, the foam 412 is compressed and buffered by the push rod 4115 and extrusion plate 4116. When the device needs maintenance, the operator rotates the knob 4112 to rotate the threaded positioning rod 4113. Under the action of the threaded hole 416, the other end of the threaded positioning rod 4113 disengages from the positioning hole 4111 in the locking block 419. At this time, the anti-collision plate 4114 can be disassembled, the locking block 419 can be removed from the engaging groove 418, and then the device can be repaired by setting... The ventilation regulation component 5 achieves better ventilation and protection. After the temperature sensor 513 detects that the high temperature reaches the set threshold, it sends the information to the controller 512. The controller 512 energizes the electromagnet 519, which then attracts the adsorption magnet 517. The reset spring 5111 is compressed, which increases the distance between the two connecting frames 515, allowing more gas to enter. When the temperature is too high, the filter screen 516 automatically opens to allow air to pass through for heat dissipation. When the temperature is too low, it automatically closes. After the electromagnet 519 is de-energized, the reset spring 5111 releases its stored energy, causing the connecting frame 515 to slide on the L-shaped limit plate 514 and align with the ventilation port 511. The filter screen 516 prevents dust from entering, thereby achieving the functions of protection, buffering, and ventilation regulation.
[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
