Description

Technical Field

[0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a semi-closed refrigerator. Background Art

[0002] Patent application number: 202410995687.0 discloses a semi-closed refrigeration device for a production workshop, including: a body, a fan and two condensers, and also includes a mounting frame for supporting the condensers and a guide component for guiding the air flow; the mounting frame includes a bottom plate and a side plate, the bottom plate is fixedly installed inside the body, a baffle is fixedly installed on the bottom plate, and the side plate has two symmetrically distributed at both ends of the bottom plate, the two condensers are inclined and symmetrically distributed between the two side plates, and two symmetrically distributed partitions are also fixedly installed between the two side plates; the semi-closed refrigeration device for a production workshop of the present invention, the air flow direction is changed by guiding the guide component, and the air flow rate of the upper and lower layers of the condenser is alternately increased, so as to facilitate relatively uniform air cooling of the upper and lower layers of the condenser, while improving the overall heat exchange performance of the condenser, reducing the loss difference between the upper and lower layers of the condenser, so as to increase the service life of the condenser.

[0003] The problem solved by the above patent is: the existing condenser is set at an angle, and the fan draws air from the top. The closer to the fan it is at the top, the greater the force with which the air is drawn and the greater the wind speed. The farther from the fan it is at the bottom, the smaller the force with which the air is drawn and the smaller the wind speed. This causes the cooling efficiency of the condenser to gradually decrease from top to bottom, and then the heat exchange performance between the upper and lower layers of the condenser is quite different, making it impossible to cool evenly. This not only affects the overall heat exchange effect of the equipment, but also causes the upper layer of the condenser to lose faster and the lower layer to lose slower, thereby increasing the loss rate of the equipment and reducing the service life of the equipment.

[0004] However, the structure of the above equipment is relatively complex, and the overall cost of the equipment is relatively high. Due to the complex structure of the equipment, more maintenance costs are generated in the subsequent maintenance process.

[0005] In addition, the existing refrigeration equipment needs to be cleaned of dust on a regular basis, which also requires maintenance costs. During the maintenance process, the equipment needs to be shut down, which affects the normal use of the equipment.

[0006] The applicant has made structural improvements to the existing equipment, and dust cleaning can be achieved by starting and stopping the equipment. The entire equipment structure is simpler, and uniform heat exchange of the condenser can be achieved, thereby increasing the service life of the condenser. Summary of the invention

[0007] In order to solve the technical problems raised in the background technology, the applicant provides a semi-closed refrigerator, and the technical solution adopted is as follows:

[0008] A semi-enclosed refrigerator comprises a shell, the material of the shell is stainless steel and the surface is coated with anti-rust paint. A compressor unit is installed at the lower part of the shell, and the compressor unit belongs to the prior art and the applicant will not elaborate on it here. The compressor unit is connected with a condenser through a pipeline, and the condenser is installed in the upper space of the shell through a fixing frame. A plurality of exhaust devices are installed at the upper part of the shell, and the exhaust devices are used to exhaust air so that air flows into the shell for heat exchange. Filters are installed in the upper spaces on the left and right sides of the shell, and the filter screens are used to filter dust and particulate matter to ensure long-term stable operation of the equipment. A plurality of inspection doors are installed at the lower part of the shell, and the inspection doors are used to open the shell to inspect the equipment.

[0009] The core improvements of the present invention are as follows: the exhaust device includes an exhaust motor, blades a and a rotating shaft. The lower part of the rotating shaft is movably mounted on a fixed frame through a bearing. The rotating shaft is provided with a plurality of blades b from the middle position downward and the diameter of the blades b increases linearly from top to bottom. Such a design increases the wind force at the bottom of the condenser, thereby forming a compensation, thereby achieving the purpose of uniform heat exchange in the entire condenser.

[0010] Preferably: filter plates are installed on both sides of the condenser respectively, and the angle between the filter plate and the horizontal plane is the same as the angle between the condenser and the horizontal plane.

[0011] Preferably: in order to achieve a better uniform heat exchange, the filter plate is provided with a plurality of filter holes from top to bottom, which are divided into area a, area b and area c, and the number of filter holes in area a, area b and area c increases from top to bottom.

[0012] Preferably: in order to achieve the purpose of automatic dust cleaning, the filter plate is provided with a plurality of knocking devices from top to bottom, and the knocking devices include a soft rope and a lightweight elastic ball. The soft rope is fixed on the filter plate, and the soft rope is connected to the lightweight elastic ball. The lightweight elastic ball contacts the filter plate under the action of the exhaust device to form a knocking effect on the filter plate. The shell is also provided with a plurality of drawers, and the drawers are used to collect dust particles.

[0013] Preferably, the surface of the light elastic ball is provided with a plurality of grooves, so that the light elastic ball can be better blown up, so that the light elastic ball contacts the filter plate to achieve the purpose of knocking the filter plate, so that the dust particles on the filter plate are knocked off and fall into the drawer.

[0014] The present invention has the following advantages: by using the present invention, the purpose of uniform heat exchange can be achieved, the structure is simpler, the production cost is lower, the filter plate can be cleaned by starting and stopping the equipment, the whole process can be achieved by the equipment itself, no additional power source is required, and the whole operation process is simple and practical.

[0024] The exhaust device includes an exhaust motor 2-1, blades a2-2 and a rotating shaft 2-3. The lower part of the rotating shaft 2-3 is movably mounted on a fixed frame 9 through a bearing. The rotating shaft is provided with a plurality of blades b2-4 from the middle position downward, and the diameter of the blades b2-4 increases linearly from top to bottom to ensure that the lower part of the condenser is compensated for the wind force. Filter plates 10 are respectively installed on both sides of the condenser 8. The angle between the filter plate 10 and the horizontal plane is the same as the angle between the condenser 8 and the horizontal plane. The filter plate 10 is provided with a plurality of filter holes from top to bottom, which are divided into area a10-1, area b10-2 and area c10-3.
