[0002] As an application of refrigeration design technology, refrigeration equipment mainly studies and selects a main engine and auxiliary engines with matching performance, and different pipeline connections form refrigeration systems with different characteristics. It is a device that is closely combined with multiple trades such as architecture, structure, heating ventilation, mechanical transmission, electric lighting, and automatic control, and is the crystallization of multi-disciplinary research. With the continuous growth of the national economy, refrigeration equipment, especially in food refrigeration and air conditioning, directly affects people's industrial production and daily life. During the operation of refrigeration equipment, it is necessary to absorb air from the outside. Since the air contains a large amount of impurities and dust, if the refrigeration equipment adsorbs a large amount of dust during operation, it will have a certain impact on the refrigeration equipment, and it is difficult to clean the dust after it enters the equipment, causing great trouble to the staff for cleaning the dust.

[0003] After retrieval, the Chinese patent publication number: CN207299693U discloses a dust-proof device for refrigeration equipment, including a dust collection hopper. The dust collection hopper is installed at the bottom end of the air inlet cylinder. A plurality of vertically arranged filter nets are provided in the air inlet cylinder. A fixed frame is provided at the top end of the air inlet cylinder. A push rod motor is installed at the top end of the fixed frame. A push rod support is provided inside the push rod motor. The bottom end of the push rod support is provided with a push rod having the same height as the filter net. A through hole is provided at the connection between the air inlet cylinder and the push rod. The bottom end of the push rod extends into the air inlet cylinder. A horizontally arranged brush is provided at the bottom of the push rod. The brush is slidably connected to the side wall of the filter net. A dust-proof cover is connected to the side of the air inlet cylinder. A suction fan is provided inside the dust-proof cover. The suction fan is closely connected to the air inlet cylinder. The side of the dust-proof cover is the air outlet. A drying box with a mesh-like transparency is provided inside the dust-proof cover.

[0004] The above-mentioned patent needs to drive the push rod and the brush to move through the push rod motor to clean the filter net, but there are still some deficiencies. Its push rod motor needs to be manually controlled. When the operator is busy, it will cause forgetting to clean the filter net, resulting in the blockage of the filter net and affecting the air flow rate. Content of the Utility Model

Specific embodiments

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] As Figure 1 shown, this embodiment discloses a main body of a dust-proof refrigeration device. The refrigeration device main body includes the refrigeration device main body 1, and the refrigeration device main body 1 is a prior art and will not be elaborated here.

[0023] A wind duct 2 is provided on one side of the refrigeration device main body 1. The wind duct 2 is used to allow external air to enter the interior of the refrigeration device main body 1 through the wind duct 2. One end of the wind duct 2 placed outside the refrigeration device main body 1 serves as the air inlet of the wind duct 2. A fixing frame 4 is installed at one end of the wind duct 2 placed inside the refrigeration device main body 1. A motor 5 is installed on the fixing frame 4, and a fan 7 is installed on the drive shaft 6 of the motor 5. A plurality of layers of dust-proof nets 3 are installed inside the wind duct 2 between the air inlet of the wind duct 2 and the fan 7. A cleaning mechanism 8 for cleaning each layer of the dust-proof net 3 is also provided inside the wind duct 2. When the refrigeration device main body is in use, the motor 5 drives the drive shaft 6 to rotate, driving the fan 7 to rotate to absorb external air. The dust-proof net 3 is used to filter a large amount of impurities and dust in the air, and the cleaning mechanism 8 is used to clean the dust adhering to the dust-proof net 3, ensuring that the dust-proof net 3 will not be blocked and affect the air flow rate, and can be automatically cleaned, saving time and effort.

[0024] Among them, please refer to Figure 2 , in this embodiment, the cleaning mechanism 8 includes a connecting member 81, a rotating shaft 82 and a brush 83. The rotating shaft 82 horizontally penetrates the centers of each layer of the dust-proof net 3, and the rotating shaft 82 is respectively rotationally matched with each layer of the dust-proof net 3. Connecting members 81 are respectively installed on the rotating shaft 82 at positions corresponding to the windward surfaces of each layer of the dust-proof net 3. Brushes 83 are symmetrically arranged on both sides of the connecting member 81. By rotating the rotating shaft 82, the brushes 83 rotate on the windward surfaces of the corresponding dust-proof nets 3, so as to effectively clean the dust-proof nets 3.

[0025] In a preferred example of this embodiment, please refer to Figure 3 , the connecting member 81 includes a connecting sleeve 811, a baffle 812, a dust cover 813, a sliding sleeve 814 and a spring 815. The connecting sleeve 811 is fixedly sleeved on the rotating shaft 82. A baffle 812 is formed on the outer wall of the connecting sleeve 811 near one end of the dust-proof net 3. A dust cover 813 is fixedly sleeved on the outer wall of the other end of the connecting sleeve 811. A sliding sleeve 814 is movably sleeved on the circumferential outer side of the connecting sleeve 811 between the baffle 812 and the dust cover 813.

[0026] Furthermore, a plurality of sliding grooves 8111 are axially formed on the outer wall of the connecting sleeve 811. Sliding blocks 8141 are respectively fixed at positions corresponding to each sliding groove 8111 inside the sliding sleeve 814. The sliding blocks 8141 are respectively slidably installed in the sliding grooves 8111 at corresponding positions. Thus, the sliding sleeve 814 can only slide axially on the connecting sleeve 811 along the axis of the connecting sleeve 811, and the baffle 812 and the dust cover 813 play a limiting role on the sliding sleeve 814, so that the sliding sleeve 814 can slide axially on the circumferential outer side of the connecting sleeve 811 and can also rotate synchronously with the connecting sleeve 811. One end of the brush 83 is fixedly connected to the sliding sleeve 814. A spring 815 is sleeved on the circumferential outer side of the connecting sleeve 811 between the sliding sleeve 814 and the dust cover 813. Even if the brush 83 gradually wears out during use and the bristles of the brush 83 become shorter, under the elastic action of the spring 815, the sliding sleeve 814 will be pushed towards the windward side of the dust-proof net 3, so that the brush 83 always keeps in contact with the dust-proof net 3 to achieve a cleaning effect and improve the service life of the brush 83.

[0027] In a preferred example of this embodiment, please refer to Figure 2 , a dust discharge port 201 is formed at the bottom of the air duct 2 near the dust-proof net 3. A dust collection box 10 is also installed at the bottom of the air duct 2. The dust collection box 10 is detachably installed with the air duct 2. The dust and impurities cleaned from the dust-proof net 3 will fall to the inner bottom end of the air duct 2 and then be discharged from the dust discharge port 201 into the dust collection box 10 for collection, which is convenient for the collection and treatment of dust and impurities.

[0028] Secondly, please refer to Figure 2, in this embodiment, the cleaning mechanism 8 is connected to the drive shaft 6 through a belt transmission mechanism 9. The belt transmission mechanism 9 includes a first pulley 91, a linkage rod 92, a bearing seat 93, a second pulley 94, a first belt 95, a third pulley 96, a fourth pulley 97, and a second belt 98. The first pulley 91 is fixedly sleeved on the drive shaft 6. The linkage rod 92 is horizontally arranged at the inner top end of the air duct 2. The linkage rod 92 is mounted on the air duct 2 through the bearing seat 93. One end of the linkage rod 92 close to the first pulley 91 is fixedly connected with the second pulley 94. The second pulley 94 and the first pulley 91 are in transmission connection through the first belt 95. The other end of the linkage rod 92 is fixedly connected with the third pulley 96. One end of the rotating shaft 82 close to the fan 7 is fixedly connected with the fourth pulley 97. The fourth pulley 97 and the third pulley 96 are in transmission connection through the second belt 98. When the drive shaft 6 drives the fan 7 to rotate to absorb air, the drive shaft 6 simultaneously drives the first pulley 91 to rotate. The first pulley 91 drives the second pulley 94 to rotate through the first belt 95. The second pulley 94 drives the linkage rod 92 to rotate. The linkage rod 92 drives the third pulley 96 to rotate. The third pulley 96 drives the fourth pulley 97 to rotate through the second belt 98. The fourth pulley 97 drives the rotating shaft 82 to rotate. Thus, while the fan 7 is working, the brush 83 is driven to rotate, realizing the cleaning work of the dust-proof net 3, without manual cleaning, saving time and effort.

[0029] In a preferred example of this embodiment, the diameter of the second pulley 94 is larger than that of the first pulley 91 and the third pulley 96, and the diameter of the fourth pulley 97 is larger than that of the third pulley 96. Through the above structural design of the pulleys, a differential speed design is achieved between the drive shaft 6 and the rotating shaft 82, which can reduce the rotation speed of the rotating shaft 82, thereby avoiding the formation of turbulent flow due to the too-fast rotation of the brush 83 and affecting the entry of air.

[0030] It should be noted that, in a preferred embodiment, the rated speed of the motor 5 is 730 r / min. The diameters of the first pulley 91 and the third pulley 96 are the same, and the diameters of the second pulley 94 and the fourth pulley 97 are the same. The diameter of the second pulley 94 is four times that of the first pulley 91, so that the rotation speed of the rotating shaft 82 is 1 / 64 of that of the drive shaft 6, that is, the rotation speed of the rotating shaft 82 is about 11 r / min. The brush 83 can not only clean the dust-proof net 3 but also not affect the entry of air.

[0031] In this embodiment, the motor is controlled by a controller. The control program of the controller can be realized by simple programming by those skilled in the art. Only by keeping the motor working can the active cleaning of the dust-proof net 3 by the brush in this embodiment be realized, without additional manual control. The control method and circuit connection will not be explained in detail in this embodiment.

[0032] The implementation principle of the main unit of a dust-proof refrigeration device in this embodiment is as follows: When the main unit of the refrigeration device is in use, the driving shaft 6 is driven to rotate by the motor 5, driving the fan 7 to rotate to absorb air from the outside. The dust-proof net 3 is used to filter a large amount of impurities and dust in the air. The driving shaft 6 simultaneously drives the first pulley 91 to rotate. The first pulley 91 drives the second pulley 94 to rotate through the first belt 95. The second pulley 94 drives the linkage rod 92 to rotate. The linkage rod 92 drives the third pulley 96 to rotate. The third pulley 96 drives the fourth pulley 97 to rotate through the second belt 98. The fourth pulley 97 drives the rotating shaft 82 to rotate. The rotating shaft 82 is used to drive the brush 83 to rotate along one side of the dust-proof net 3, so as to effectively clean the dust-proof net 3. The dust and impurities cleaned from the dust-proof net 3 will fall into the inner bottom end of the air duct 2, and then be discharged from the ash discharge port 201 into the ash collection box 10 for collection, which is convenient for the collection and treatment of dust and impurities. This utility model ensures that the dust-proof net 3 will not be blocked and affect the air flow rate, and can be automatically cleaned, saving time and effort.
