Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner outdoor unit bracket, a water-cooled outdoor unit, and a combined structure that are fastened to an inner wall. Background Technology

[0002] The installation of existing split-type air conditioners' outdoor units is extremely inconvenient, inevitably involving high-altitude work. The brackets, fixed to the building's exterior wall with expansion bolts, also pose significant safety hazards. Over time, the heavy outdoor unit may detach due to rust or loose wall surfaces, potentially falling and causing disastrous consequences. In areas with strict regulations on high-altitude work on exterior walls, coupled with high labor costs, installation costs increase dramatically, severely limiting the widespread adoption of split-type air conditioners. For transient populations, the cost of disassembly and reassembly is also substantial, and refrigerant leaks during the process cause environmental pollution. Window units in integrated systems are nearly obsolete due to the need for a large opening in the wall. Portable air conditioners, which avoid the installation problems of outdoor units, have seen significant growth recently, but their large exhaust ducts are extremely inconvenient, affecting aesthetics, and significantly reducing cooling efficiency. Summary of the Invention

[0003] In view of this, the present invention aims to propose an air conditioner outdoor unit bracket, a water-cooled outdoor unit and a combined structure that are fastened to the inner wall, so that the installation of the air conditioner outdoor unit is no longer dangerous, the cost is reduced, and users can even complete it themselves; it introduces an easy-to-install water-cooled portable air conditioner outdoor unit to replace the air-cooled duct, which greatly improves the cooling efficiency, does not affect the indoor aesthetics, and is also simple and convenient to relocate.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: An air conditioner outdoor unit bracket fastened to an interior wall includes a main structural body for supporting the outdoor unit, connecting components extending into the interior wall, and fasteners located within the interior wall. The connecting components extending into the interior wall pass through holes in the wall or cross the wall through windows, and are then fastened to the interior wall by the fasteners. The weight of the outdoor unit is borne by the entire wall, not the exterior wall surface. The main structural body and the connecting components extending into the interior wall are integrated or fastened together, with the bottom of the main structural body bent to form support feet that support the outdoor unit.

[0005] Furthermore, the connecting component extending to the inner side of the wall is made of steel pipe and is firmly welded to the main structure used to support the outdoor unit of the air conditioner. The outer diameter of the pipe is adapted to the diameter of the air conditioner pipe hole preset in the wall. The end of the pipe is chamfered to facilitate insertion into the wall hole. The front end is threaded and the fastener is threaded to be tightened into the inner wall. The inner hole of the pipe can be used for pipelines and power lines to pass through.

[0006] Furthermore, a swing arm is also fitted onto the steel pipe fitting. The bottom of the swing arm is also bent to form a support foot. The swing arm can swing to an appropriate angle with the main body of the support, so that the swing arm support foot and the main body support foot can jointly support the outdoor unit of the air conditioner.

[0007] Furthermore, to accommodate situations where the wall hole is close to one side and to prevent the outdoor unit of the air conditioner from tilting to one side, the swing arm is designed with an adjustable length structure.

[0008] This utility model also provides a water-cooled outdoor unit, which, when applied to a portable air conditioner, replaces the traditional air-cooled condenser with a water-cooled condenser and adds a circulating water pump and a return water tank. The water-cooled outdoor unit is installed outdoors. The water-cooled outdoor unit consists of a cooling water tank and a matching cooling fan. The upper end of the cooling water tank is provided with a water inlet and connected to an upper water storage tank, and the lower end is provided with a lower water storage tank and connected to a water outlet. Between the upper and lower water storage tanks is a radiator core composed of rows of heat dissipation pipes and densely distributed heat dissipation fins. The cooling fan is installed close to the radiator core, and the heat dissipation pipes are connected to both the upper and lower water storage tanks.

[0009] This utility model also provides a combined structure of a water-cooled outdoor unit and an air conditioner outdoor unit bracket. The water-cooled outdoor unit is fastened to the main structure of the outdoor unit bracket. The steel pipe fittings can be directly placed on the window sill or window frame. A set of pressure plates for the steel pipe fittings is added between the fasteners and the inner wall to clamp the wall.

[0010] Furthermore, the fastener is fitted with a sleeve-shaped structure at the front of the steel pipe fitting and interlocked with threads to increase the adjustment range.

[0011] In another combined structure, the connecting component extending to the inner side of the wall is made of steel sheet metal and is a C-shaped component clamped to the window frame. Bolts are used as fasteners to secure the inner side of the C-shaped component to the inner side of the wall. The main structure supporting the outdoor unit of the air conditioner is also made of steel sheet metal and is integrated with the outer side of the C-shaped component.

[0012] Furthermore, the C-shaped component is made into an adjustable structure, which can be adjusted appropriately according to the wall thickness.

[0013] The air conditioner outdoor unit bracket, water-cooled outdoor unit, and combined structure that are fastened to an inner wall according to this utility model have the following advantages: The weight of the outdoor unit is borne by the entire wall, not just the exterior surface, ensuring reliable load-bearing and preventing detachment. The recommended installation location is below the windowsill. The outdoor unit can be hoisted into place from inside the house using ropes or other methods, and then secured to the interior wall, avoiding the dangers of working at heights. For portable air conditioners, installation is even simpler; it can be directly mounted across the windowsill without drilling, facilitating disassembly and relocation. The water-cooled portable air conditioning system maximizes cooling efficiency by adding a water circulation cooling system on the outdoor side, maximizing heat removal. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. The embodiments described herein are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0017] It should be noted that the terms "upper", "lower", "left", "right", "front", "rear", 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 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.

[0018] As shown in Figure 1, the bracket body 12 and the swing arm 13 are forked at a certain angle, and the bottom of the bracket body 12 is bent to form a support foot 14. The support foot is fixedly connected to the corresponding mounting holes on the bottom mounting base 31 of the air conditioner outdoor unit 3 through several fixing holes 15 (not shown in the figure). The support feet of the bracket body 12 and the swing arm 13 together support the air conditioner outdoor unit 3. As shown in Figure 2, in this embodiment, the connecting member 11 extending to the inner side of the wall is made of steel pipe and is firmly welded to the main structure 12 that supports the air conditioner outdoor unit. The outer diameter of the pipe is adapted to the pre-set diameter of the air conditioner pipe hole in the wall. The end inserted into the wall hole is chamfered for easy insertion, and the front end is threaded. The fastener 2 is threaded and tightened into the inner wall. The inner hole of the pipe can allow pipes and power lines to pass through. The upper end of the swing arm 13 has a sleeve hole adapted to the outer diameter of the pipe 11, so that the swing arm 13 can swing at a certain angle with the support body 12 with the pipe as the axis to adjust the distance between the two support feet 14 to adapt to different air conditioner outdoor unit sizes. To adapt to the situation where the wall hole is close to one side, and to prevent the air conditioner outdoor unit from tilting, the swing arm 13 is made of an adjustable length structure. It can be adjusted appropriately according to the tilt of the air conditioner outdoor unit to return it to the correct position. This structure is simple and easy to implement, and will not be shown in the figure again. The pipe 11 can also be made of stainless steel to improve the rust resistance.

[0019] As can be seen from the above description, the installation of the outdoor unit of the air conditioner no longer requires drilling holes in the external wall to install an external bracket. The load-bearing position is in the wall hole, and then distributed to the wall, which greatly improves the reliability. The key to the entire installation process is to insert the steel pipe fitting 11 into the wall hole, and then tighten the fastener 2 to secure it to the inner wall.

[0020] Traditional air conditioner outdoor units, containing compressors and numerous surrounding refrigeration devices, are very heavy, making installation difficult and hindering their widespread application. Portable air conditioners, on the other hand, avoid the installation problems of outdoor units, but their large exhaust pipes are extremely inconvenient, affecting aesthetics and significantly reducing cooling efficiency. To solve these problems, it is necessary to modify them to be water-cooled. The modified water-cooled outdoor unit is lightweight and easy to install, without causing too much trouble, while greatly improving cooling efficiency. The small cooling water pipes are also easy to lay out, making relocation easier.

[0021] As shown in Figure 3, the portable air conditioner water-cooled outdoor unit 3 is almost identical to a conventional automotive engine radiator, consisting of a coolant tank 30 and a cooling fan 32. The coolant tank 30 has an inlet nozzle 33 at its upper end, connected to an upper water tank 35; the lower water tank 36 is connected to an outlet nozzle 34. Between the upper and lower water tanks is a radiator core 37, composed of rows of heat dissipation pipes and densely packed heat dissipation fins. The heat dissipation pipes are connected to both the upper and lower water tanks, allowing coolant to flow from the upper water tank into the lower water tank via the heat dissipation pipes. The radiator core has sufficient heat dissipation area, and the cooling fan 32, installed close to it, dissipates heat into the surrounding atmosphere. This is mature existing technology and will not be illustrated or described in detail. Similar to automotive engine radiators, the upper water tank 35 also includes a water tank cap (fill port) and a water overflow device, which will not be illustrated or described further. The portable air conditioner unit also needs to be modified accordingly, replacing the traditional air-cooled condenser with a water-cooled condenser, and adding a return water tank and a circulating water pump. The cooling water pipes are divided into supply water pipes and return water pipes. The circulating water pump pumps the water stored in the return water tank through the supply water pipe in the cooling water pipe to the inlet nozzle 33, which enters the upper storage tank 35. After flowing through the radiator core 37 and being cooled, the water enters the lower storage tank 36. Then, through the outlet nozzle 34, the water is sent to the inlet of the water-cooled condenser through the return water pipe in the cooling water pipe to be cooled and turned into high-temperature water. The water then returns to the return water tank from the outlet of the water-cooled condenser, forming a water-cooled circulating cooling system. The cooling water pipes use high-temperature resistant soft rubber tubing, preferably silicone tubing. In this embodiment, the power supply lines for the cooling water pipe and the cooling fan are connected to the indoor and outdoor environments through the inner hole of the fitting 11. The condensate produced by the evaporator is injected into the circulating water in the return water tank. When the total water volume is excessive, it can be discharged outdoors through the overflow device of the upper water tank, eliminating the need for a separate condensate collection / discharge device and ensuring that the cooling water is always sufficient. The modification of the portable air conditioner unit can be easily completed by technicians in the air conditioning and refrigeration industry and is not the focus of this patent, so it will not be illustrated or described in detail here. This mode can be applied not only to portable air conditioners but also to integrated kitchen air conditioners, etc.

[0022] The aforementioned cooling water tanks can also be arranged in a left-right configuration, where the radiator cores between the left and right water tanks have rows of heat dissipation pipes arranged horizontally. The heat dissipation pipes are connected to both the left and right water tanks, and cooling water can enter the right water tank from the left water tank through the heat dissipation pipes. The heat dissipation effect is roughly the same, which is suitable for long and large heat dissipation requirements. Further details will not be provided here.

[0023] As shown in Figure 4, the portable air conditioner cooling water tank 30 and its matching cooling fan 32 are mounted together on the bottom of the main body 12 of the bracket, bent to form a support foot 14 and fixed thereon.

[0024] As shown in Figure 5, the steel pipe connecting component 11, which is integrated with the main structure 12, passes through the hole opened in the wall 4 and then emerges from the inner wall. The fastener 2 is fitted onto the threaded front end of the pipe and tightened, thereby firmly fixing the main structure 12 and the water-cooled outdoor unit 3 it carries.

[0025] As shown in Figure 6, the portable air conditioner water-cooled outdoor unit 3 is lighter because it does not need to be filled with cooling water during installation. It can be easily placed on the window sill and window frame 42 without the trouble of drilling. To ensure a secure installation, a set of pressure plates 5 for the steel pipe fitting 11 is added between the fastener 2 and the inner wall 4 to clamp the wall. After installation and connection of the cooling water pipe, the cooling water can be filled. A soft pad can be placed under the pipe fitting 11. The sliding window is pushed to the right all the way to abut against the pipe fitting 11. The gap between the sliding window and the window frame above the pipe fitting 11 is filled with elastic heat insulation material to maintain airtightness.

[0026] Figure 7 is a rear view of the portable air conditioner water-cooled outdoor unit 3 and the bracket directly straddling the windowsill. This figure clearly shows the clamping condition of the pressure plate 5 against the wall and the condition of the wrench jaw 21. Of course, the fastener 2 can also be a hexagonal nut.

[0027] Figure 8 is a schematic diagram of a portable air conditioner water-cooled outdoor unit and bracket directly mounted on the windowsill for use in a top-and-bottom sliding window structure, which is basically similar to a left-and-right sliding window and will not be described in detail again.

[0028] To accommodate different wall thicknesses, as shown in Figure 9, fastener 2 is fitted with a sleeve-like structure that fits onto the front of pipe fitting 11 and is threaded together (thread not shown). This structure can be adjusted according to the wall thickness. This structure can also be applied to through-wall hole patterns.

[0029] As shown in Figures 10 and 11, the connecting component 11 extending to the inner side of the wall is made of steel sheet metal and is C-shaped, clamped to the window sill frame. Bolts are used as fasteners 2 to secure the inner side of the C-shape to the inner side of the wall. The main structure 12 supporting the outdoor unit of the air conditioner is also made of steel sheet metal and is integrated with the outer side of the C-shaped component 11. Its lower end is bent to form a support foot 14, which, together with the side of the main structure 12, fixes and supports the water-cooled outdoor unit 3. The power supply lines for the cooling water pipes and cooling fan pass through and are fixed through the upper end of the connecting component 11, and are not shown in the figure. The fasteners 2 can also be expansion bolts.

[0030] To accommodate different wall thicknesses, the C-shaped component 11 can be made into an adjustable structure, which can be adjusted appropriately according to the wall thickness. This structure is simple and easy to implement, and will not be shown in a separate diagram.

[0031] When the water-cooled outdoor unit is relatively light, the C-shaped component and main structure can also be made of aluminum alloy or even copper. In this embodiment, steel or stainless steel is preferred. The C-shaped component and main structure can also be made using casting (die casting) process, but the cost is higher.

[0032] The solutions shown in Figures 6 to 11 are particularly suitable for houses with very thick walls and rental properties, avoiding drilling operations, greatly reducing the difficulty of air conditioner installation, and making relocation easier.

[0033] For the sake of simplicity, the above embodiments are all described using a single-cooling air conditioner as an example. In fact, they can all be applied to both cooling and heating air conditioners. The problem can be solved simply by adding a four-way valve, which can be easily solved by air conditioning and refrigeration professionals, and will not be elaborated further.

[0034] The above description is merely an embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model. Unless expressly stated otherwise, no element, action, or instruction used herein should be construed as critical or necessary.
