It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Fig. 1 is a schematic structural view of a display case, fig. 2 is a schematic structural view of a partial section of the display case taken along line a-a, and fig. 3 is a schematic structural view of a section of the display case taken along line a-a. As shown in fig. 1, 2 and 3, the showcase includes a machine room 1, a refrigerating room 2, a bottom chassis 3, and the like. The refrigerating chamber 2 is provided on the base frame 3, and includes a glass cabinet door 21, left and right side plates 22, a back plate 23, a top plate 24, and a bottom plate 25. The machine room 1 is provided above the refrigerating room 2. The machine room 1 may be mainly enclosed by a ceiling cover 11, a front baffle 12, a back cover 13, upward extending portions of both left and right side plates 22 of the refrigerating room 2, and a bottom plate 25 of the refrigerating room 2, wherein the ceiling cover 11 has an air suction opening 14, the back cover 13 has an air suction opening 15, and a lower portion 121 of the front baffle 12 has an air blowing opening 123.
As shown in fig. 2, a fan 4, a condenser 5, and a compressor 6 are provided in the machine room 1, wherein the compressor 6 is installed at a rear position of the machine room 1, that is, at a position close to the back plate cover 13, and the condenser 5 is installed between the fan 4 and the compressor 6. As shown in fig. 3, the fan 4 generates convection air, and the air is sucked from the air suction port 14 of the top plate cover 11 and the air suction port 15 of the back plate cover 13 in the direction indicated by arrows in fig. 3, heated by the condenser 5 and the compressor 6, and blown out from the air outlet 123.
In the above embodiment, preferably, the machine chamber 1 further includes a baffle 7. The baffle 7 may be disposed at a position where the blower 4 is located to divide the machine room 1 into an air duct 16 and a machine accommodating space 17. The baffle 7 has a mounting hole 18 capable of accommodating a blade of the fan 4, so that the hot air heated by the condenser 5 and the compressor 6 enters the air duct 16 through the mounting hole 18 and is blown out from the air outlet 123. Due to the function of the baffle 7, the hot air heated by the condenser 5 and the compressor 6 is prevented from returning to the mechanical accommodating space 17 due to the rebound of the front baffle 12, so that the force blown out by the air outlet 123 can be improved, the dew removing effect is improved, and the refrigerating effect can be improved.
In the above embodiment, it is preferable that the front baffle 12 includes an upper portion 124, a lower portion 121 and a connecting portion 122, wherein the lower portion 123 protrudes outward relative to the upper portion 124, so that the air outlet 123 is close to the outer surface of the glass cabinet door 21. The lower portion 123 and the upper portion 124 are connected to the upper portion 124 by the connecting portion 122. With the structure, the air outlet 123 of the lower part 121 can blow hot air along the outer surface of the glass cabinet door 21, so that the dew removing effect is improved. More preferably, the connecting portion 122 is a slope, so that the upper portion 124 and the lower portion 121 are in a transition connection with a slope, thereby blowing the hot air in the air duct 16 out of the air outlet 123 more smoothly, and further improving the anti-dew effect.

By adopting the structure, the defect of insufficient range of downblow anti-dew air caused by overlong glass door of the overhead display cabinet is overcome, so that the problem of anti-dew below the glass door cannot be effectively solved.
In the above embodiment, it is preferable that three sides of the duct plate 8 are hermetically attached to the bottom plate 25 of the display case, the other side is connected to the upper blowing duct front cover 31, and the duct plate 8 and the upper blowing duct front cover 31 are fixed by a fixing member 33 to constitute the upper blowing duct 10. One end of the upper blowing air duct 10 is an air outlet 32 of the upper blowing air duct front cover 31, and air is sucked from the outside of the air duct plate 8 by the upper blowing fan 9 to generate convection air, and the air is blown out from the air outlet 32 through the upper blowing air duct 10 in a direction indicated by an arrow in fig. 6.
In the above embodiment, preferably, the upper blowing duct front cover 31 is disposed on a front edge of the bottom plate 25 of the display cabinet near the glass cabinet door 21, and protrudes outward relative to an outer surface of the glass cabinet door 21, so that the air outlet 32 can be close to the outer surface of the glass cabinet door 21. By adopting the structure, the air outlet 32 of the upper blowing air duct front cover 31 can blow air along the outer surface of the glass cabinet door 21, so that the dew removing effect is improved.
In the above embodiment, the machine room 1 may be mainly formed by enclosing the top plate cover 11, the front baffle plate 12, the back plate cover 13, the upward extending portions of the left and right side plates 22 of the refrigerating room 2, and the refrigerating room 2. However, the present invention is not limited to this, and the machine room 1 may have independent left and right side plates and a bottom plate, and may be mainly surrounded by a ceiling shield 11, a front baffle 12, a back shield 13, left and right side plates of the machine room 1, and a bottom plate of the machine room 1.
