[0025] In order to enable those skilled in the art to better understand the technical solutions in the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the utility model.

[0026] It should be noted that the terms "upper" and "lower" indicate directions or positional relationships based on the directions or positional relationships shown in the auxiliary figures, and are only for the purpose of simplifying the description of the present invention, rather than indicating or implying that the device referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention. Specifically, in the present invention, the user's operating surface is the front, the direction toward the ground is the bottom, and conversely, the direction away from the ground is the upper, and other descriptions indicating directions are defined based on "upper" and "lower".

[0027] In various drawings of the present invention, for the convenience of illustration, some dimensions of structures or parts are exaggerated relative to other structural parts, and therefore, are only used to illustrate the basic structure of the subject matter of the present invention.

[0028] like Figures 1 to 8 As shown, the utility model provides a refrigeration device, wherein the refrigeration device comprises: a box body (not shown), a compressor compartment 100 formed at the rear lower part of the box body, a fan 132 located in the compressor compartment 100, and a windshield 131 arranged around the fan 132, wherein the windshield 130 is interference fit with the inner wall of the compressor compartment 100, the windshield 131 comprises a storage groove 1310 penetrating along its thickness direction, and the fan 132 abuts against the groove wall of the storage groove 1310. The setting of the windshield 131 divides the compressor compartment into two independent spaces to achieve rapid heat dissipation. At the same time, the setting of the windshield can also play a good vibration reduction effect and reduce the impact of noise, thereby improving the user experience.

[0029] Reference Figures 1 to 3 The compressor compartment 100 includes a housing 110 and a bottom plate 120, a compressor 140 and a condenser 150 are mounted on the bottom plate 120, the condenser has a condensation pipe 151 connected to the compressor 140, and a fan 132 and a wind shield 131 are located between the compressor 140 and the condenser 150. The high-temperature and high-pressure refrigerant is discharged from the outlet pipe of the compressor 140, enters the condenser 150 through the condensation pipe 151, and performs forced air convection heat exchange with the surrounding air through the fan 132 to perform cooling and heat dissipation.

[0030] In this embodiment, the thickness of the windshield 131 is between 5 mm and 15 mm, which can stably support the fan, and at the same time, the windshield 131 can absorb the wind noise generated by the fan 132. Preferably, the windshield 131 is made of thermoplastic plastic, for example, a polyethylene windshield, and the material density of the polyethylene windshield is 50±10Kg / m 3 , which can achieve good vibration reduction and noise reduction effects.

[0031] Reference Figure 4 and Figure 7 As shown, the storage slot 1310 includes a slot wall, on which adhesive S may be pre-applied, and the adhesive S is used to be fixedly connected to the housing of the fan 132, and is used to stably constrain the fan to the storage slot 1310. It can be understood that, since the thickness of the wind shield 131 is between 5 mm and 15 mm, the width of the slot wall of the storage slot 1310 (here the width of the slot wall is equal to the thickness of the wind shield) is smaller than the width of the housing of the fan 132 (here the width of the fan housing refers to the length from the air inlet to the air outlet). Among them, the slot wall is smaller in width than the housing of the fan, so that the volume occupied by the wind shield in the compressor compartment 100 becomes smaller, which helps to obtain a compact windshield structure.

[0032] Reference Figure 4 and Figure 5 In one embodiment of the utility model, one of the fan 132 and the wind shield 131 is provided with a fixing hole 1321, and the other is provided with a matching seam 1322 corresponding to the fixing hole 1321 and fixed to the fixing hole 1321 by a cable tie. The fan 132 and the wind shield 131 are fixed for a second time by a fixing component such as a cable tie, so as to improve the bonding strength between the fan 132 and the wind shield 131, and avoid the relative position movement of the wind shield 131 and the fan 132 due to the vibration of the compressor 140. In this embodiment, the fixing hole 1321 is located on the fan 132, and the matching seam 1322 is provided on the wind shield 131.

[0033] Continue to refer to Figure 4 , Figure 5 and Figure 8 The windshield 131 includes a plurality of side walls 131a, which enclose a storage groove 1310. The side walls 131a are provided with at least one cable winding groove 1311, which is connected to the outside of the windshield 131. When the fan 132 is fitted in the storage groove 1310, the cable of the fan 132 can be wound in the cable winding groove 1311, so as to solve the cable arrangement problem. The cable is used to provide power to the fan 132.

[0034] Furthermore, the winding groove 1311 extends obliquely from the side wall 131a, and the opening of the winding groove 1311 is located on the edge of the side wall 131a and away from the receiving groove 1310. Preferably, the winding groove 1311 and the edge of the side wall 131a are arranged at an angle of 30°-60°, and the obliquely extending winding groove 1311 is convenient for winding.

[0035] like Figure 5 As shown, there are two winding grooves 1311 , which are respectively arranged on adjacent and connected side walls 131 a , and the oblique extension directions and angles of the two winding grooves 1311 are the same.

[0036] Reference Figure 2 , Figure 4 and Figure 6 The wind shield 131 includes a bottom side wall 131b assembled on the bottom plate 120 of the compressor compartment 100, the bottom side wall 131b has a first adaptation structure, and the bottom plate 120 of the compressor compartment 100 has a second adaptation structure. The second adaptation structure and the first adaptation structure are concave-convexly adapted to each other so as to divide the compressor compartment 100 into two independent spaces. At the same time, the displacement of the wind shield 131 on the bottom plate 120 can also be limited.

[0037] Among them, the first adaptation structure is, for example, a first concave slope 1312 formed at the corner of the bottom side wall 131b; the second adaptation structure is, for example, a first protrusion 121 formed on the bottom plate 120; wherein the first protrusion 121 is an arc-shaped protrusion which abuts against the first concave slope 1312, thereby restricting the displacement of the wind shield 131 on the bottom plate 120.

[0038] Understandably, Figure 6 The first and second adapter structures of the concave-convex adapter shown in the figure are only for illustrative purposes. In other embodiments of the present invention, the shape of the adapter structure on the windshield can be adjusted according to the shape of the adapter structure on the base plate 120.

[0039] Reference Figure 7 and Figure 8The bottom side wall 131b further includes a slit 1314, which divides the bottom side wall 131b into a discontinuous first portion and a second portion. When the fan 132 is installed in the receiving slot 1310 of the wind shield 131, the slit 1314 provides a gap so that the first portion and the second portion of the bottom side wall 131b are separated, which facilitates the installation of the fan 132 in the receiving slot 1310.

[0040] In addition, refer to Figure 7 The windshield 131 is provided with a through hole 1315 for the condenser 151 to pass through. Specifically, the through hole 1315 is provided on the side wall 131a. The through hole 1315 and the first adapting structure are arranged diagonally, so that the windshield 131 can be used with the condenser 150. In this embodiment, the side wall 131a is, for example, a lateral side wall parallel to the bottom plate 120, and the lateral side wall is located above the storage groove 1310. The lateral side wall also includes an elongated groove, which extends from the edge toward the through hole 1315 and is connected to the through hole 1315, so that the condenser 151 is more easily assembled into the through hole 1315.

[0041] The refrigeration device also includes a bracket 152 for fixing the condenser 150. The wind shield 132 is provided with an avoidance groove (not shown) for avoiding the bracket 152. The bracket 152 abuts against the inner wall of the avoidance groove, so that the wind shield and the compressor compartment are further fixed.

[0042] Preferably, the wind shield 131 also has a limiting portion (not shown) for limiting the bracket 152 from falling off from the avoidance groove, the bracket is located at the rear lower part of the compressor compartment, the avoidance groove is located at the rear lower part of the wind shield, the limiting portion extends downward from the outside of the avoidance groove, and the bracket and the limiting portion abut against each other.

[0043] Continue to refer to Figure 4 and Figure 7 The side wall 131a further includes a vertical side wall, and a wing portion 1314 extends from the outer edge of the vertical side wall. The wing portion 1314 abuts against the top of the evaporating dish 160, so that the wind shield 131 is better able to withstand force in the vertical direction.

[0044] In summary, the refrigeration equipment provided by the utility model has a windshield with a thickness of less than 15 mm and greater than 5 mm, and the windshield can be assembled with the fan, which has the advantages of simple combination, easy assembly and good vibration reduction effect. In addition, the windshield itself is provided with a winding groove for storing the fan cable. In addition, a through hole is added on the windshield to match the refrigerant outlet pipe of the condenser; at the same time, the fan and the windshield are fixed to the condenser bracket plate by a rolling belt, forming a stable assembly structure, which improves the overall reliability of use.
