Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a water receiving box and its compressor chamber. Background Technology

[0002] Refrigeration display cases are commonly used in convenience stores and supermarkets to sell chilled beverages and other products. Due to limited space, many convenience stores and supermarkets place display cases close to the wall, often side-by-side. The air in front of the display cases is cooler, higher-quality air, while the air behind them is warmer, lower-quality air. The compressor compartment of the display case is typically designed with front intake and rear exhaust. Because the display case is close to the wall, only a portion of the air can be expelled from the compressor compartment. (See reference...) Figure 1 The air drawn in by the condenser fan exchanges heat with the compressor and condenser, but only a portion of it is discharged from the compressor compartment. Some of the air bounces back to the side wall of the compressor compartment through the rear cover or wall and is drawn back in by the condenser fan. This results in poor heat exchange in many existing compressor compartment products with front and rear air outlets, leading to frequent problems such as poor cooling and shutdown. Utility Model Content

[0003] To address the problems of poor heat exchange in the compressor compartment, frequent refrigeration issues, and compressor shutdowns in existing technologies, the first objective of this utility model is to provide a water collection box, including a box body. The box body is provided with a first air distribution plate and a second air distribution plate protruding from the box body. The first air distribution plate and the second air distribution plate converge from both sides towards the middle, which is used to divide the compressor compartment into an air inlet path located in the middle and an air return path located on both sides.

[0004] Specifically, the first and second air distribution plates are hollow ribbed structures.

[0005] Specifically, the first and second air distribution plates have a gap with the front end of the water receiving box. The first and second air distribution plates divide the water receiving box into a first area and a third area on both sides, and a second area in the middle. The first area, the second area and the third area are connected through the gap.

[0006] Specifically, the bottom of the water receiving box is provided with multiple buckles, and a heating tube is installed in the buckles.

[0007] Specifically, the heating tube is disposed in the first region and the second region.

[0008] Specifically, the first air distribution plate and the second air distribution plate are in the shape of a cubic curve, the length of the first air distribution plate is greater than the length of the second air distribution plate, and the maximum curvature of the first air distribution plate is less than the maximum curvature of the second air distribution plate.

[0009] Specifically, the water receiving box is U-shaped, and an installation groove is provided on the rear side of the water receiving box.

[0010] The second objective of this utility model is to provide a press chamber, including a press chamber, wherein an internal cavity is provided in the press chamber, and the aforementioned water receiving box is provided in the internal cavity.

[0011] Specifically, the press chamber includes a front cover, a rear cover, a bottom plate, a top plate, and side walls. A first air inlet is provided on the front side of the bottom plate or in the front cover, a second air inlet is provided in the mounting groove, and an air outlet is provided in the rear cover.

[0012] Specifically, a condenser, a condenser fan, and a compressor are provided on the rear side of the compressor compartment, and the first air distribution plate and the second air distribution plate shield the front end of the condenser on both sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention incorporates a first and second air distribution plate within the water collection box. These plates divide the compressor compartment into an inlet air path and a return air path. After heat exchange with the compressor and condenser, some hot air exits the compressor compartment through the rear cover, while some hot air remains inside the compressor compartment and rebounds into the return air path. During its passage through the return air path, the hot air comes into contact with the bottom plate, side walls, and condensate, losing some heat and lowering its temperature. It then mixes with fresh air drawn in from the first inlet air path at the front of the compressor compartment and is re-inhaled into the inlet air path. The placement of the first and second air distribution plates increases system resistance, reducing the proportion of return air re-entering the inlet air path, and also extends the distance of the return air path, allowing for a more thorough temperature reduction in the return air. These two methods work in parallel to lower the average inlet air temperature entering the condenser, resulting in an overall temperature reduction of approximately 10°C at the rear of the compressor compartment. This improves the heat exchange efficiency of the condenser and thus enhances the product's cooling performance. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] like Figures 2-6 As shown, this utility model provides a water receiving box, which is installed in the compressor compartment of refrigeration equipment such as display cabinets and freezers. It includes a box body, within which are a first air distribution plate 21 and a second air distribution plate 22 protruding from the box body. The first air distribution plate 21 and the second air distribution plate 22 converge from both sides towards the middle, dividing the compressor compartment into an inlet air path in the middle and return air paths on both sides. Air drawn into the compressor compartment exchanges heat with the compressor 4 and condenser 3 through the inlet air path. The resulting hot air leaves from the outlet 16 or bounces back into the return air path. The return air path mixes with the inlet air path, effectively extending the hot air return path and preventing hot air that does not leave from the outlet 16 from being directly drawn into the condenser fan 5, thus avoiding poor heat exchange.

[0026] The compressor chamber includes a front cover 11, a rear cover (not shown in the figure), a bottom plate 12, a top plate (not shown in the figure), and side walls 13. A first air inlet 14 is provided on the front side of the bottom plate 12 or in the front cover 11, and an air outlet 16 is provided in the rear cover. Display cases installed in convenience stores, supermarkets, and other similar settings are usually placed side by side against a wall. The air in front of the display case is high-quality air with a lower temperature, while the air behind the display case is low-quality air with a higher temperature. The first air inlet 14 is provided on the front side of the bottom plate 12 or in the front cover 11 to facilitate the intake of high-quality, low-temperature air into the compressor chamber. In some embodiments, a second air inlet 15 is also provided in the middle of the bottom plate 12. The second air inlet 15 is located in front of the condenser 3 to increase the area of ​​the air inlet and increase the air volume.

[0027] The compressor compartment contains a compressor 4, a condenser 3, a condenser fan 5, and a water collection box 2. The water collection box 2 is located on the front side of the compressor compartment and is fixedly installed on the base plate. The compressor 4, condenser 3, and condenser fan 5 are located on the rear side of the compressor compartment. Because the compressor 4 generates a large amount of heat during operation and its temperature is relatively high, to optimize the airflow distribution within the compressor compartment and increase the airflow passing through the compressor 4, the condenser 3 is positioned close to one side wall 13 of the compressor compartment, and the compressor 4 is positioned close to the other side wall 13 of the compressor compartment. For example, the condenser 3 is positioned slightly to the left, and the compressor 4 is positioned slightly to the right.

[0028] The water receiving box 2 is U-shaped, with a mounting groove 26 on its rear side. The condenser 3 is housed in the mounting groove 26. The first air distribution plate 21 and the second air distribution plate 22 shield the front end of the condenser 3 on both sides. The second air inlet 15 is located on the front side of the mounting groove 26, and the condenser 3 is located on the rear side of the mounting groove 26. The condenser fan 5 and the compressor 4 are located on the rear side of the condenser 3. The water receiving box 2 contains the first air distribution plate 21 and the second air distribution plate 22, with the first air distribution plate 21 located away from the compressor 4 and the second air distribution plate 22 located closer to the compressor 4. The first air distribution plate 21 and the second air distribution plate 22 are hollow rib structures that protrude significantly from the box body, dividing the air inlet and return paths in the compressor compartment. The water receiving box 2 is made of plastic material, and the rib structure of the first air distribution plate 21 and the second air distribution plate 22 has poor thermal conductivity, preventing heat from the return path from being conducted into the air inlet path.

[0029] Specifically, the air intake path is formed by the top plate, bottom plate 12, first air distribution plate 21 and second air distribution plate 22. The return air path includes a first return air path and a second return air path. The first return air path is composed of the top plate, bottom plate 12, side wall 13 and first air distribution plate 21. The second return air path is composed of the top plate, bottom plate 12, side wall 13 and second air distribution plate 22.

[0030] The first air distribution plate 21 and the second air distribution plate 22 are in the shape of a cubic curve, converging from both sides to the middle. The inlet sections of the air intake and return air paths smoothly cut in with a large radius of curvature, collecting airflow and reducing the impact loss of the intake air. The middle and rear sections form a converging flow channel, and the airflow achieves stable and uniform acceleration before the outlet.

[0031] Understandably, the first air distribution plate 21 and the second air distribution plate 22 can be installed either in the water receiving box 2 or upside down at the bottom of the top plate.

[0032] The condenser fan 5 draws air in through the first air inlet 14 and the second air inlet 15. The air is then drawn into the rear of the compressor compartment via the air intake path. After heat exchange with the compressor 4 and condenser 3, some of the hot air leaves the compressor compartment through the rear cover, while some remains inside the compressor compartment and rebounds into either the first or second return air path. During its passage through the return air path, the hot air comes into contact with the base plate 12, side walls 13, and condensate, losing some heat and lowering its temperature. Subsequently, it mixes with fresh air drawn in from the first air intake path at the front of the compressor compartment and is re-drawn into the air intake path. The first and second air distribution plates 21 and 22, positioned on the air intake side of the condenser 3, increase system resistance, reducing the proportion of return air re-entering the air intake path, and also extend the distance of the return air path, allowing for a more thorough temperature reduction of the return air. These two methods work together to lower the average air intake temperature entering the condenser 3. Compared with existing technologies, the overall temperature at the rear of the compressor compartment is reduced by about 10°C, which improves the heat exchange efficiency of condenser 3 and thus improves the cooling performance of the product.

[0033] The first air distribution plate 21 and the second air distribution plate 22 are disposed in the water receiving box 2, and there is a narrow gap 28 between the air distribution plate and the front end of the water receiving box 2. The first air distribution plate 21 and the second air distribution plate 22 divide the water receiving box 2 into a first region 23 and a third region 25 located on both sides, and a second region 24 located in the middle. The first region 23, the second region 24 and the third region 25 are connected by the gap 28. The condensate from the refrigeration equipment flows into the second region 24 of the water receiving box 2, and flows into the first region 23 and the third region 25 through the gap 28. The hot air in the first return air path and the second return air path accelerates the evaporation of the condensate. A heating pipe 31 is also disposed in the water receiving box 2. The heating pipe 31 extends from one side of the condenser 3 into the water receiving box 2. The bottom of the water receiving box 2 is provided with multiple clips 27. The heating pipe 31 extends from the first region 23 into the water receiving box 2 and is fixed in the water receiving box 2 by the clips 27. Heating element 31 heats the water in the first zone 23 and the second zone 24, increasing the water temperature in the water collection box 2 and accelerating the evaporation of condensate. The first zone 23 and the third zone 25 of the water collection box 2 use hot air to accelerate condensate evaporation, and the condensate in the first zone 23 and the second zone 24 is heated by heating element 31, further accelerating evaporation. The dual heating effect of hot air return and heating element 31 in the condenser 3 improves the evaporation efficiency of the condensate.

[0034] The gaps between the air intake and return ducts are sealed by filling them with a soft material. Specifically, soft material is provided between the first and second air distribution plates 21 and the condenser 3, and between the first and second air distribution plates 21 and the top plate. The soft material fills and fixes the gaps, completely separating the air intake and return ducts. The soft material is preferably a sealing strip or similar material.

[0035] Furthermore, a baffle plate 32 is provided on the back of the condenser 3, away from the compressor 4. The baffle plate 32 has an opening 33. The baffle plate 32 adjusts the airflow of the first and second return air paths, ensuring that most of the rebounding hot air exchanges heat with the compressor 4. After cooling in the second return air path, it mixes with fresh air. The first air distributor 21 and the second air distributor 22 have the same projected length in the front-to-back direction, but the length of the first air distributor 21 is greater than that of the second air distributor 22. The maximum curvature of the first air distributor 21 is less than that of the second air distributor 22. The net flow area of ​​the second return air path is greater than that of the first return air path, resulting in lower system resistance and a greater airflow volume, thus improving the heat dissipation effect of the compressor 4. A small portion of the hot air enters the first return air path through the opening 33, cools down, and then mixes with fresh air.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
