DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0021] The core of the utility model is to provide an air outlet device for a cold storage, which solves the problem that the cooling air entering the cold storage is unevenly distributed and the air outlet volume cannot be adaptively adjusted, resulting in poor cooling effect and high energy consumption of the cold storage.

[0022] Figure 1 This is a schematic diagram of the structure of a cold storage air outlet device provided by the utility model. Figure 2 This is a schematic diagram of the enlarged structure of point A provided by the utility model. Figure 3 This is a schematic diagram of the enlarged structure of the B provided by the utility model, see Figures 1 to 3 shown.

[0023] Example 1

[0024] A cold storage air outlet device, see Figure 1 The air outlet of the air cooler 1 is connected to the main air supply duct 2, and the cooling air enters the main air supply duct 2 from the air outlet of the air cooler 1. A plurality of air outlets 5 are arranged on the bottom side of the main air supply duct 2, and each air outlet 5 is connected to an air expansion pipe 6. The cold air in the main air supply duct 2 is sent from the air outlet 5 to the inside of the cold storage 3 via the air expansion pipe 6. In some feasible implementations, the width of the air expansion pipe 6 on one side close to the main air supply duct 2 is smaller than the width of the bottom of the air expansion pipe 6. The cold air coming out of the air outlet 5 enters the top of the cold storage 3 in a diffused shape under the guidance of the wall of the air expansion pipe 6, and passes through each air expansion pipe 6. The cold air entering the top of the cold storage 3 can be evenly distributed and diffused to the bottom of the cold storage 3. During the actual setting process, the air outlets 5 are evenly distributed laterally on the bottom side of the main air supply duct 2, and each air outlet 5 is spaced at least one distance of an air outlet 5 to facilitate the subsequent installation of the adjustment component 8. The air expansion pipe 6 can make the range of the cold air from the air outlet 5 entering the cold storage 3 larger than the width of the air outlet 5. Therefore, the range of the cold air from each air outlet 5 after entering the cold storage 3 through the air expansion pipe 6 can just match or overlap a little, so that the incoming cold air can fully and evenly cover the top space of the cold storage 3.

[0025] See also Figure 1An electric telescopic rod 7 located inside the main air supply duct 2 is fixed to the inner wall of the top of the cold storage 3 away from the air cooler 1. An adjusting component 8 is fixed to the protruding end of the electric telescopic rod 7. The bottom of the adjusting component 8 corresponds to the air outlet 5. By controlling the extension of the electric telescopic rod 7, the adjusting component 8 can be pushed to block the air outlet 5. By adjusting the extension amount of the electric telescopic rod 7, the area of ​​the air outlet blocked by the adjusting component 8 can be controlled, thereby realizing the main air supply duct 2 to adjust the air intake of the cold storage 3 and controlling the main air supply duct 2 to stop the air intake into the cold storage 3. In some feasible implementation methods, refer to Figure 3 The adjusting assembly 8 includes a horizontal push rod 800 fixed to the extended end of the electric telescopic rod 7. The electric telescopic rod 7 is extended to push the horizontal push rod 800 to move forward in the horizontal direction, driving the vertical rod 810 fixed on the horizontal push rod 800 to move forward together. A baffle 820 that conflicts with the bottom side of the main air supply duct 2 is fixed at the bottom of the vertical rod 810. The vertical rod 810 drives the baffle 820 to move forward together, thereby blocking the air outlet 5. As the forward moving distance of the horizontal push rod 800 and the vertical rod 810 increases, the area of ​​the air outlet 5 blocked by the baffle 820 continues to increase, and the amount of cold air that can flow out of the air outlet 5 gradually decreases. It should be noted that when it is necessary to completely stop the air intake at the top of the cold storage 3, It is necessary that the baffle 820 can completely block the air outlet 5, so the width of the baffle 820 is greater than or equal to the width of the air outlet 5. Furthermore, to ensure the blocking effect, the baffle 820 includes an upper baffle and a lower baffle. The width of the upper baffle is greater than the width of the air outlet 5, and the four sides of the lower baffle can conflict with the inner side of the air outlet 5. The lower baffle is fixed to the middle part of the bottom side of the upper baffle. Both are not drawn in the figure. In this way, when the baffle 820 is completely moved to the top of the air outlet 5, the lower baffle can be directly embedded in the air outlet 5 to completely block the air outlet 5, ensuring that cold air will not continue to leak out from the gap between the baffle 820 and the air outlet 5, so as to facilitate more precise control of the adjustment of the air intake of the cold storage 3.

[0026] The cold air diffuses downward from the top of the cold storage 3. The temperature at the bottom of the cold storage 3 drops more slowly than the temperature at the top of the cold storage 3. To ensure that the temperature of all areas inside the cold storage 3 drops to the required storage temperature as quickly and evenly as possible, the two ends of the main air supply duct 2 are respectively connected with branch ducts 4 fixed to the two vertical sides of the cold storage 3. The bottom end of the branch duct 4 is sealed, and a control valve 9 is provided at the connection between the branch duct 4 and the main air supply duct 2. Figure 1When the temperature at the top of the cold storage 3 drops to the required storage temperature, the air intake of the main air supply duct 2 is reduced or suspended by adjusting the component 8, and the control valve 9 is opened, and the cold air in the main air supply duct 2 enters the branch duct 4. A plurality of inclined openings 10 are arranged on one side of the branch duct 4 close to the inside of the cold storage 3. The cold air in the branch duct 4 enters the cold storage 3 from both sides of the cold storage 3 along the inclined openings 10. At this time, the air cooler 1 still keeps supplying a certain amount of cold air, but part or all of the cold air can be guided to both sides of the cold storage 3 through the branch duct 4, so that the cold air can be diffused in multiple directions from the top and both sides of the cold storage 3, thereby improving the uniformity of the diffusion and distribution of the cold air in the entire cold storage 3, ensuring that all areas of the cold storage 3 can reach the specified storage temperature in a relatively short time, and the main air supply duct 2 and the branch duct 4 can realize the effective utilization of the cold air supplied by the air cooler 1 in a balanced manner, avoiding unnecessary energy waste.

[0027] Example 2

[0028] On the basis of Example 1, the baffle 820 includes a sealing baffle 821 and a hole baffle 822, and the sealing baffle 821 and the hole baffle 822 are arranged at intervals. Figure 1 When the baffle 820 completely blocks the air outlet 5, in order to prevent the temperature of the top of the cold storage 3 from changing during the downward diffusion of cold air from the top of the cold storage 3, the cold air in the main air supply duct 2 can still flow out from the holes on the hole baffle 822 into the top of the cold storage 3, and the air outlet 5 corresponding to the sealing baffle 821 will no longer flow out cold air, thereby ensuring that the air volume of the main air supply duct 2 can be reduced, so that most of the cold air in the main air supply duct 2 can be distributed to the branch duct 4, thereby achieving uniform distribution of cold air in the cold storage 3.

[0029] Further, in some feasible implementations, an inner wall of the branch pipe 4 close to the inside of the cold storage 3 is provided with an inclined plate 11 corresponding to the top and bottom edges of the inclined opening 10, see Figure 2The cold air in the branch pipe 4 can be diverted and guided by the inclined plate 11, so that the cold air in the branch pipe 4 can evenly flow out from the inclined port 10 along the inclination angle of the inclined plate 11 and enter the cold storage 3. The inclination angles of the inclined plate 11 and the inclined port 10 can guide the diffusion direction of the cold air, so that the cold air is evenly distributed in the cold storage 3. Specifically, the inclined port 10 and the inclined plate 11 close to the air cooler 1 are both inclined downward, that is, the cold air at the top of the branch pipe 4 is inclined downward from the inclined port 10 along the downward inclination angle of the inclined plate 11 to enter the cold storage 3, and no longer repeatedly enters the top of the cold storage 3, but directly enters the cold storage 3 from both sides, so that the upper and middle parts of the cold storage 3 are The temperature of the cold storage 3 is reduced. Similarly, the inclined port 10 and the inclined plate 11 near the bottom of the branch pipe 4 are inclined upward. The cold air at the bottom of the branch pipe 4 follows the upward inclination angle to reduce the temperature of the middle and lower parts of the cold storage 3, and as the cold air diffuses downward, the temperature at the bottom of the cold storage 3 can also drop to the required storage temperature as soon as possible. The cold air is distributed to both sides of the cold storage 3 through the branch pipe 4, and the flow direction of the cold air is guided by the angles of the inclined plate 11 and the inclined port 10, so that multi-directional air intake of the cold storage 3 can be achieved, and the uniformity of the air intake of the cold storage 3 is improved. Preferably, the inclined port 10 is installed with a grid plate, which can further make the cold air flowing out of the inclined port 10 more evenly distributed.

[0030] When the electric telescopic rod 7 drives the horizontal push rod 800 and the vertical rod 810 to move forward, in order to prevent the vertical rod 810 from pushing the baffle 820 due to friction and cold air resistance, causing the adjustment component 8 to shift, and to reduce the wear on the vertical rod 810, inclined rods 12 are fixed on both sides of the vertical rod 810, and the bottom ends of the inclined rods 12 are fixed to the top side of the baffle 820. A stable triangular structure is formed by the two inclined rods 12, which provide support for the vertical rod 810 from both sides, thereby improving the stability of the adjustment component 8 and extending the service life of the vertical rod 810.

[0031] In the utility model, cold air enters the main air supply duct 2 through the air outlet of the air cooler 1, and enters the interior of the cold storage 3 through each air outlet 5 via each air expansion pipe 6. The air expansion pipe 6 can make the cold air diffuse into the top of the cold storage 3, so that the cold air is evenly distributed and continues to diffuse to the bottom of the cold storage 3. The electric telescopic rod 7 is controlled to extend, and the adjustment component 8 can be pushed to block the air outlet 5. By adjusting the extension amount of the electric telescopic rod 7, the area of ​​the air outlet 5 blocked by the adjustment component 8 can be controlled, thereby realizing the adjustment of the air intake of the cold storage 3 or stopping the top air intake. When the temperature at the top of the cold storage 3 has dropped to the required storage temperature, the air intake of the main air supply duct 2 is reduced or suspended by the adjustment component 8, and the branch duct 4 is opened. The control valve 9 at the connection with the main air supply duct 2 allows the cold air in the main air supply duct 2 to enter the branch ducts 4. The cold air moves to the two sides of the cold storage 3 through the branch ducts 4, and enters the inside of the cold storage 3 from the two sides of the cold storage 3 through the inclined openings 10, so that the diffusion and distribution of the cold air in the entire cold storage 3 is more uniform. The air cooler 1 still maintains quantitative air supply, but part of the cold air can be guided to the two sides of the cold storage 3 through the branch ducts 4, so that the cold air can be diffused in multiple directions from the top and both sides of the cold storage 3, thereby improving the distribution uniformity of the cold air entering the cold storage 3, ensuring that all areas of the cold storage 3 can reach the specified storage temperature in a relatively short time, and evenly utilizing the cold air delivered by the air cooler 1 to avoid unnecessary energy waste.
