Description

Technical Field

[0001] The present invention relates to the technical field of air handling equipment, in particular to a rooftop unit and an air conditioning unit. Background Art

[0002] A rooftop unit is a unitary integral unit of an all-air system, which can integrate functions such as refrigeration, heating, air supply, air purification, and electric control. Since it is generally installed on the roof of a building, it is called a rooftop unit. Due to its advantages of compact structure, wide range of refrigeration (heating) capacity, convenient debugging, easy installation, and low investment and maintenance costs, rooftop units are widely used in industries such as metallurgy, chemical industry, and electromechanics, as well as in places such as theaters, shopping malls, restaurants, and bars. Especially in many shopping malls, factories, and small office premises in the Americas and the Middle East, rooftop units can be seen everywhere.

[0003] For currently vertically distributed rooftop units, a partition is used to divide the frame to form an upper cavity and a lower cavity. The upper cavity can be directly exposed to the air, while the lower cavity needs to be connected to the interior and requires strict sealing to prevent water from entering the lower cavity.

[0004] However, whenever it rains, the rainwater falling into the upper cavity will drain from the periphery of the upper cavity, and the drained rainwater will flow down along the frame or the outer surface of the rooftop unit, and it is very easy to enter the lower cavity along the assembly gap, causing potential safety hazards. Summary of the Invention

[0005] In order to solve the technical problem that water easily enters the lower cavity in the prior art and causes potential safety hazards, a rooftop unit and an air conditioning unit are provided, in which a water collection structure is arranged on the partition to prevent water from flowing into the lower cavity.

[0006] A rooftop unit includes:

[0007] A frame;

[0008] A partition, the partition is arranged on the frame, and the partition divides the frame into an upper cavity and a lower cavity;

[0009] A water collection structure, the water collection structure is arranged on the partition, and the water collection structure is used to receive the water on the partition and / or in the upper cavity.

[0010] The water collection structure includes a water collection groove, and the water collection groove is arranged at the edge of the partition.

[0011] A flanging is arranged at the edge of the partition, and the flanging forms the water collection structure.

[0012] A drain hole is arranged on the water collection structure.

[0013] On the installation platform where the rooftop unit is located, the projection of the drain hole is located outside the projection of the lower cavity.

[0014] The rooftop unit further includes a drainage structure, and the drainage structure is communicated with the drain hole.

[0015] The drainage structure includes a drain pipe, and the first end of the drain pipe is communicated with the water collection structure.

[0016] The rooftop unit is arranged on the installation platform, and the second end of the drain pipe is lower than the plane where the installation platform is located.

[0017] The number of the drain holes is at least two, and all the drain holes are evenly distributed on the water collection structure.

[0018] The rooftop unit further includes a sealing plate, and the sealing plate and the partition board jointly enclose the lower cavity, and the sealing plate and the partition board are hermetically arranged.

[0019] An air-conditioning unit includes the above-mentioned rooftop unit.

[0020] For the rooftop unit and the air-conditioning unit provided by the present invention, a water collection structure is arranged on the partition board, and rainwater flowing out from the upper cavity is collected by the water collection structure, so as to avoid water flow from entering the lower cavity through assembly gaps, etc., and ensure the reliable use of the rooftop unit.

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0027] As Figures 1 to 3The shown rooftop unit includes: a frame 1; a partition 2, which is disposed on the frame 1, and the partition 2 divides the frame 1 into an upper cavity 11 and a lower cavity 12; a water collection structure 3, which is disposed on the partition 2, and the water collection structure 3 is used to receive the water on the partition 2 and / or in the upper cavity 11. By arranging the water collection structure 3 on the partition 2, rainwater and the like flowing out of the upper cavity 11 are collected by the water collection structure 3, thus preventing water from entering the lower cavity 12 through assembly gaps and the like, ensuring the reliable use of the rooftop unit.

[0028] As an implementation manner, the water collection structure 3 includes a water collection tank, and the water collection tank is disposed at the edge of the partition 2. The rainwater discharged from the upper cavity 11 will flow onto the partition 2 and flow into the water collection tank, or can directly flow into the water collection tank, and finally all are collected by the water collection tank. At this time, rainwater and the like will not flow into the lower cavity 12, thus ensuring the reliable use of the rooftop unit.

[0029] As another implementation manner, a folded edge is provided at the edge of the partition 2, and the folded edge forms the water collection structure 3. That is, the edge of the partition 2 is bent to form a folded edge, and the folded edge can form a water collection area with a certain depth on the upper surface of the partition 2. The water in the upper cavity 11 can flow into the water collection area and be collected, preventing water from flowing into the lower cavity 12.

[0030] To prevent the capacity of the water collection structure 3 from being too small to collect all the water, a drain hole 31 is provided on the water collection structure 3. The drain hole 31 can discharge the water in the water collection structure 3 to ensure the reliable water collection of the water collection structure 3. Moreover, setting the drain hole 31 can drain water at a specific position of the water collection structure 3, further preventing water from entering the lower cavity 12.

[0031] To further improve the sealing effect of the lower cavity 12, the position of the lower cavity 12 corresponding to the drain hole 31 can be strengthened in sealing, such as adding sealing materials.

[0032] On the installation platform where the rooftop unit is located, the projection of the drain hole 31 is located outside the projection of the lower cavity 12. That is, the water flow of the drain hole 31 will not flow along the outer wall surface of the lower cavity 12, preventing the problem of water seepage due to gaps on the outer wall surface of the lower cavity 12 caused by assembly and other problems, and further improving the reliability of the rooftop unit.

[0033] The rooftop unit further includes a drainage structure, and the drainage structure is communicated with the drain hole 31. The drainage structure is used to forcibly discharge the rainwater and the like collected in the water collection structure 3, improving the reliable water collection of the water collection structure 3 for rainwater and the like.

[0034] As an implementation manner, the drainage structure includes a drain pipe, and the first end of the drain pipe is communicated with the water collecting structure 3. By utilizing the drainage effect of the drain pipe, the water in the water collecting structure 3 is drained to a set position, further reducing the possibility of water flowing into the lower cavity 12 and improving the reliability of the rooftop unit.

[0035] The rooftop unit is disposed on an installation platform, and the second end of the drain pipe is lower than the plane where the installation platform is located. That is, at this time, the drain pipe drains the water in the water collecting structure 3 to a position lower than the lower cavity 12. At this time, the water flow will surely not be able to enter the lower cavity 12, effectively ensuring the reliability of the rooftop unit.

[0036] To improve the drainage efficiency of the water collecting structure 3, the number of the drain holes 31 is at least two, and all the drain holes 31 are uniformly distributed on the water collecting structure 3. As Figure 1 shown, the shape of the partition plate 2 is rectangular. At this time, the number of the drain holes 31 is two, and the two drain holes 31 are respectively located at two opposite top corners of the rectangle, enabling the water in the partition plate 2 and the water collecting structure 3 to be drained smoothly. At the same time, the drainage volumes borne by the two drain holes 31 are basically the same, avoiding the problem that the drainage volume of a certain drain hole 31 is too large to be drained in time and improving the reliability of the water collecting structure 3.

[0037] The rooftop unit further includes a sealing plate, and the sealing plate and the partition plate 2 jointly enclose the lower cavity 12, and the sealing plate and the partition plate 2 are hermetically arranged, thereby forming a completely sealed lower cavity 12 and further improving the waterproof effect of the lower cavity 12.

[0038] An air-conditioning unit includes the above-mentioned rooftop unit

[0039] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
