Technical Field
[0001] The present invention relates to the technical field of heat and cold exchange of refrigeration equipment, and particularly relates to a condensate drainage structure for preventing heat and cold exchange. Background Art
[0002] Bar counters are generally applied to indoor places such as bars, hotels, and restaurants, and are often used to display and sell beverages such as beer and drinks. In the existing bar counters on the market, the inside of the evaporator is directly connected to the outside of the compressor, and the condensate is directly discharged to the compressor side, resulting in relatively serious heat and cold exchange between the two, affecting the refrigeration performance of the equipment and increasing the power consumption of the bar counter itself. At the same time, the installation base is mostly made of metal sheet metal parts, with a high production cost and increased weight, which is not conducive to subsequent use, installation, and movement. Summary of the Invention
[0003] The purpose of the present invention is to solve the deficiencies existing in the above-mentioned prior background art and provide a condensate drainage structure for preventing heat and cold exchange.
[0004] To solve the above technical problems, the technical solution adopted by the present invention is: a condensate drainage structure for preventing heat and cold exchange, including a bottom plate of the compressor chamber. An evaporator installation cavity, a compressor installation cavity, a condenser installation cavity, and an evaporator fan installation cavity are provided on the upper side of the bottom plate of the compressor chamber. A blocking structure is provided between the evaporator installation cavity and the compressor installation cavity, and at least one drainage hole for connecting the two cavities is provided on the blocking structure. The bottom surface of the evaporator installation cavity has an inclination, and its lowest point converges and is connected to the drainage hole.
[0005] On the front side and the rear side of the top of the drainage hole, a front baffle and a rear baffle extending downward are respectively provided. The lower edges of the front baffle and the rear baffle do not contact the bottom surface of the drainage hole and are at the same height. A blocking plate extending upward is provided on the bottom surface of the drainage hole between the two baffles. The setting position of the blocking plate is close to the front baffle, and the upper edge of the blocking plate is set lower than the top surface of the drainage hole and higher than the lower edges of the two baffles. The lowest height of the inner bottom surface of the evaporator installation cavity is greater than the lower edge setting height of the rear baffle.
[0006] Further, the bottom surface of the evaporator installation cavity includes three bottom plates, which are spliced in an inverted cone shape, and the lowest edge converges into a drainage groove. The outlet end of the drainage groove is connected to the drainage hole.
[0007] Further, the front baffle and the rear baffle are parallel to each other and perpendicular to the bottom surface of the drainage hole. The blocking plate is parallel to the front and rear baffles.
[0008] Further, the lowest height of the inner bottom surface of the evaporator installation cavity is higher than the upper edge setting height of the blocking plate.
[0009] Further, the front end of the bottom surface of the drainage hole is flush with the bottom surface of the compressor installation cavity.
[0010] Furthermore, the bottom plate of the press chamber is injection-molded from polypropylene material and integrally formed.
[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention is made of an injection-molded structure, with a simple structure, convenient installation, lighter weight, low production cost, and can be adapted and applied to other types of products; it can achieve the independent pre-assembly of the refrigeration system, which can not only ensure the smooth flow of condensed water into the compressor side for evaporation, but also prevent the heat of the external compressor from entering the internal evaporator side and affecting the refrigeration performance, reducing the heat and cold exchange between the refrigeration systems, improving the refrigeration performance, and reducing energy consumption.

[0017] It should be noted that in the description of the present invention, terms such as "upper", "lower", "front", "rear", "top surface", "bottom surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only relational terms determined for the convenience of describing the structural relationships of the various components of the present invention, and do not specifically refer to any component of the present invention that must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as a limitation of the present invention.
[0018] Secondly, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0019] The following further describes the specific embodiments of the present invention in detail with reference to the drawings:
[0020] As Figure 1 and Figure 2 shown, a condensate drainage structure for preventing heat and cold exchange includes the bottom plate 1 of the press chamber, the overall structure of which is made of polypropylene material by injection molding and integrally formed to achieve lightweight setting of the structure. An evaporator installation cavity 2, a compressor installation cavity 3, a condenser installation cavity and an evaporator fan installation cavity are provided on the upper side of the entire bottom plate 1 of the press chamber, so as to facilitate prefabricated assembly and be applicable to the assembly of various different types of refrigeration equipment.
[0021] A transverse blocking structure 4 is provided between the evaporator installation cavity 2 and the compressor installation cavity 3 provided on the bottom plate 1 of the press chamber. Through the fitting and installation of the bottom plate 1 of the press chamber with each fitting in the entire refrigeration equipment, the evaporator and the compressor in the refrigeration equipment are in two mutually isolated different spaces, avoiding the mutual influence during operation between the two; however, since condensate is easily generated during the operation of the evaporator, in order to avoid water accumulation and better drain the condensate, a drainage hole 5 communicating the evaporator installation cavity 2 and the compressor installation cavity 3 is provided on the blocking structure 4. The bottom plate of the evaporator installation cavity 2 is spliced into an inverted cone shape by one rear triangular plate and two side trapezoidal plates, having a certain slope to facilitate the condensate to gather and flow out; the lowest edges of the splicing edges of the three different bottom plates converge to form a drainage trough 6 with a higher rear and a lower front. The front end of the drainage trough 6 is connected to the drainage hole 5 on the blocking structure 4.
[0022] Referring to Figure 3 and Figure 4 , a front baffle 51 and a rear baffle 52 are respectively extended downward at the front side and the rear side positions of the top of the drainage hole 5, and the two are parallel to each other and perpendicular to the bottom surface of the drainage hole; the lower edges of the front baffle 51 and the rear baffle 52 do not contact the bottom surface of the drainage hole, leaving a space for the condensate to flow out, and at the same time, the lower edge setting heights of the front baffle 51 and the rear baffle 52 are the same. A blocking plate 53 extending upward is provided on the bottom surface of the drainage hole between the front baffle 51 and the rear baffle 52, parallel to the front and rear baffles, and the setting position is close to the front baffle 51; the upper edge setting height of the blocking plate 53 is lower than the top surface of the drainage hole 5 and higher than the lower edge setting heights of the front and rear baffles. At the same time, the front end setting height of the drainage trough 6 inside the evaporator installation cavity 2 is higher than the lower edge setting height of the rear baffle 52 and higher than the upper edge setting height of the blocking plate 53, avoiding the backflow of the condensate when it is discharged. The front end of the bottom surface of the drainage hole 5 is flush with the bottom surface of the compressor installation cavity 3, facilitating the condensate to flow to the compressor side for evaporation.
[0023] The special height settings of the front side wall of the above-mentioned evaporator installation cavity 2, the rear baffle 52, the blocking plate 53, and the front baffle 51 form a "U-shaped" condensate outflow channel. By using the liquid level height difference, a part of the condensate always remains in the drain hole 5, which not only achieves the sealing effect, blocks the hot gas exchange between the compressor side and the evaporator side, improves the refrigeration performance of the equipment, and reduces energy consumption, but also can smoothly discharge the condensate on the evaporator side to the compressor side for evaporation, avoiding the influence of condensate backflow on electrical safety.
[0024] The technical features not detailed in the present invention can be realized by adopting or referring to the relevant technical solutions in the prior art.
[0025] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
