Description

Technical Field

[0001] This utility model belongs to the field of multi-split air conditioning technology, and in particular relates to a water pump bracket for a multi-split indoor unit. Background Technology

[0002] Multi-split indoor units often use foam stamping as the water pump fixing point. However, the space in ultra-thin multi-split indoor units is relatively small, and it is necessary to ensure the distance between the float, the water pump, and the foam. The strength of foam material is relatively low, and it may deform or crack under the weight of the water pump and the vibration during operation for a long time, which will affect the fixing effect and service life of the water pump. Therefore, foam stamping is not suitable as the water pump fixing point for ultra-thin multi-split indoor units.

[0003] Therefore, there is an urgent need to design a water pump bracket for multi-split indoor units to solve the problem mentioned above where the material strength of foam stamping is low, making it difficult to ensure the distance between the float and the water pump / sponge. Utility Model Content

[0004] To address the technical problem mentioned in the background art—that the material strength of foam stamping is low, making it difficult to ensure the distance between the float, the water pump, and the sponge—a water pump bracket for a multi-split indoor unit is provided to solve the aforementioned problem.

[0005] To achieve the above objectives, the specific technical solution for the water pump bracket of the multi-split indoor unit of this utility model is as follows:

[0006] A water pump bracket for a multi-split indoor unit includes a bracket base plate, on which a water pump is mounted. A first side plate is fixedly connected to the side of the bracket base plate, and a bending plate is fixedly connected to the first side plate. A float is mounted on the bending plate, and a sponge limiting plate is fixedly connected to the side of the bending plate to limit the sponge.

[0007] Furthermore, a float mounting hole is provided on the bending plate, and a first nut and a second nut are screwed onto the float. The first nut and the second nut are located on opposite sides of the float mounting hole. After the float passes through the mounting hole, the first nut and the second nut are rotated to clamp the bending plate with the first nut and the second nut, thereby fixing the position of the float.

[0008] Furthermore, the float mounting hole is a through hole to allow the float to move within it, thereby enabling the float to be positioned on the bending plate.

[0009] Furthermore, a first clearance hole is provided on the sponge limiting plate, which is connected to the float mounting hole, and the size of the first clearance hole matches that of the float mounting hole.

[0010] Furthermore, the bracket base plate has a first water pump fixing hole, a second water pump fixing hole, a third water pump fixing hole and a fourth water pump fixing hole. Four bolts pass through the first water pump fixing hole, the second water pump fixing hole, the third water pump fixing hole and the fourth water pump fixing hole respectively to install the water pump on the bracket base plate.

[0011] Furthermore, the base plate of the bracket is provided with a water pump limiting hole, the shape of which matches the water pump to limit the water pump.

[0012] Furthermore, it also includes a second side plate, on which a conduit through-hole is provided so that the water pump pipeline can pass through the second side plate.

[0013] Furthermore, a first connecting plate is fixedly connected to the first side plate, a second connecting plate is fixedly connected to the second side plate, and a third connecting plate is fixedly connected to the base plate of the bracket. Water pump baffle fixing holes are provided on the first connecting plate, the second connecting plate, and the third connecting plate. Bolts pass through the water pump baffle fixing holes to install the water pump baffle on the first connecting plate, the second connecting plate, and the third connecting plate.

[0014] Furthermore, it also includes the casing of the multi-split indoor unit, with the bracket base plate installed on the casing of the multi-split indoor unit. A water tray is installed inside the casing of the multi-split indoor unit, and the water tray is located above the water pump and float, thereby fixing the position of the float, water pump, water tray, and sponge.

[0015] Furthermore, it is made of 1mm thick stainless steel.

[0016] The water pump bracket for the multi-split indoor unit of this utility model has the following advantages:

[0017] This utility model satisfies the modular installation of water pump and float in confined spaces, which is convenient to operate and saves space. The float position is adjustable to meet the installation requirements of normal working distance in confined spaces. At the same time, the structure is made of 1mm thick stainless steel, which ensures the stability of the structure and avoids problems such as deformation and cracking. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0024] The following is a reference to the appendix. Figure 1 To be continued Figure 3 This utility model describes the water pump bracket for the indoor unit of a multi-split air conditioning system.

[0025] The existing foam materials have relatively low strength. Over time, bearing the weight of the water pump 6 and the vibrations during operation, they may deform or crack. This can cause the float 7 to rub against the water pump 6 or the sponge 8, preventing the float 7 from floating normally. Consequently, the water pump 6 may fail to start, resulting in condensate overflow and affecting the fixing effect and lifespan of the water pump 6. Therefore, foam stamping is not suitable as a fixing point for the water pump 6 in ultra-thin multi-split indoor units.

[0026] Therefore, this utility model provides a water pump bracket for a multi-split indoor unit, such as... Figures 1-3As shown, the system includes a bracket base plate 1, on which a water pump 6 is mounted. A first side plate 2 is fixedly connected to the side of the bracket base plate 1, and a bending plate 3 is fixedly connected to the first side plate 2. The bending plate 3 is a horizontal plate, and a float 7 is mounted on the bending plate 3. A sponge limiting plate 4 is fixedly connected to the side of the bending plate 3 to limit the movement of the sponge 8. Specifically, the bracket base plate 1 is installed on the housing 10 of the multi-split indoor unit, and the water pump 6 is mounted on the bracket base plate 1. The float 7 is mounted on the bending plate 3. The float 7 and the sponge 8 are located between the sponge limiting plate 4 and the multi-split indoor unit casing 10. To elaborate, the water pump 6 is installed on the bracket base plate 1, the float 7 is installed on the bending plate 3, and the sponge 8 is abutted against the sponge limiting plate 4 between the sponge limiting plate 4 and the multi-split indoor unit casing 10 through the sponge limiting plate 4, thereby forming a fixed relative distance between the float 7 and the water pump 6 and the sponge 8, thus meeting the distance requirements between the float 7 and the water pump 6 and the sponge 8 in the narrow space of the ultra-thin multi-split indoor unit.

[0027] As a preferred option, such as Figure 1 and Figure 2 As shown, the bent plate 3 has a float mounting hole 301. A first nut 701 and a second nut 702 are screwed onto the float 7. The first nut 701 and the second nut 702 are located on opposite sides of the float mounting hole 301. After the float 7 passes through the float mounting hole 301, the first nut 701 and the second nut 702 are rotated to clamp the bent plate 3, thereby fixing the position of the float 7 so that it can be installed and removed by the operator.

[0028] Preferably, the float mounting hole 301 is a through hole, allowing the float 7 to move within the float mounting hole 301, thereby adjusting the position of the float 7 on the bending plate 3. This solves the problem of the float 7 rubbing against the water pump 6 or the sponge 8 by adjusting the position of the float 7 within the float mounting hole 301.

[0029] Preferably, the sponge limiting plate 4 has a first clearance hole 401, which is connected to the float mounting hole 301. The size of the first clearance hole 401 matches that of the float mounting hole 301, so that the float 7 can directly enter the float mounting hole 301 from the side. That is, the float 7 directly enters the float mounting hole 301 from the side of the sponge limiting plate 4, which is convenient for personnel to install and remove.

[0030] As a preferred option, such as Figure 3 As shown, the bracket base plate 1 has a first water pump fixing hole 101, a second water pump fixing hole 102, a third water pump fixing hole 103 and a fourth water pump fixing hole 104. Four bolts pass through the first water pump fixing hole 101, the second water pump fixing hole 102, the third water pump fixing hole 103 and the fourth water pump fixing hole 104 respectively to install the water pump 6 on the bracket base plate 1, thereby facilitating personnel disassembly and maintenance.

[0031] As a preferred option, such as Figure 3 As shown, the bracket base plate 1 has a water pump limiting hole 105. The shape of the water pump limiting hole 105 matches the water pump 6 to limit the water pump 6. Preferably, the water pump limiting hole 105 is located within the pattern formed by the line connecting the first water pump fixing hole 101, the second water pump fixing hole 102, the third water pump fixing hole 103, and the fourth water pump fixing hole 104, so as to facilitate the installation of the water pump 6 and improve the structural reliability of the connection between the water pump 6 and the bracket base plate 1.

[0032] As a preferred option, such as Figure 1 As shown, it also includes a second side plate 5, on which a conduit through hole 501 is provided so that the pipeline of the water pump 6 can pass through the second side plate 5.

[0033] Preferably, a first connecting plate 201 is fixedly connected to the first side plate 2, a second connecting plate 502 is fixedly connected to the second side plate 5, and a third connecting plate 106 is fixedly connected to the bracket base plate 1. Water pump baffle fixing holes 100 are provided on the first connecting plate 201, the second connecting plate 502, and the third connecting plate 106. Bolts pass through the water pump baffle fixing holes 100 to install the water pump baffle on the first connecting plate 201, the second connecting plate 502, and the third connecting plate 106.

[0034] As a preferred option, such as Figure 2 As shown, it also includes the multi-split indoor unit casing 10, the bracket base plate 1 is installed on the multi-split indoor unit casing 10, and a water tray 9 is installed on the multi-split indoor unit casing 10. The water tray 9 is located above the water pump 6 and the float 7, thereby fixing the positions of the float 7, water pump 6, water tray 9 and sponge 8. This meets the requirements of the relatively small space of the ultra-thin multi-split indoor unit, which is to ensure the distance between the water pump 6 and the water tray 9 according to the capacity of the water tray 9, and also to ensure the distance between the float 7 and the water pump 6, water tray 9 and sponge 8.

[0035] As a preferred option, the water pump bracket of the multi-split indoor unit is made of 1mm thick stainless steel with a nickel content of 12%, thus ensuring low thermal conductivity, corrosion resistance and easy processing of the water pump bracket of the multi-split indoor unit.

[0036] In one specific embodiment, the space of the ultra-thin multi-split indoor unit is small, and the distance between the water pump 6 and the float 7 needs to be controlled at 2-3mm, and the distance between the float 7 and the sponge 8 needs to be controlled at 5-6mm. However, the stainless steel multi-split indoor unit provided by this utility model has tolerances in its processing. At this time, it is difficult to meet the requirements of the distance between the three, which will cause the float 7 to scrape against the water pump 6 or the sponge 8, the float 7 cannot float up and down normally, and the water pump 6 cannot start normally, causing condensate to overflow. Therefore, the problem of processing tolerance is solved by using the sponge limiting plate 4 to hold the sponge 8 and adjusting the position of the float 7 through the float mounting hole 301.

[0037] This utility model satisfies the modular installation of water pump 6 and float 7 in confined spaces, which is convenient to operate and saves space. In addition, the position of float 7 is adjustable to meet the installation requirements of normal working distance in confined spaces. At the same time, the structure is made of 1mm thick stainless steel, which ensures the stability of the structure and avoids problems such as deformation and cracking.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
