Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner in which the outdoor unit is fastened to the 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 from the building with disastrous consequences. In Western countries with extremely strict regulations on high-altitude exterior wall work, coupled with high labor costs—installation fees often several times the price of the air conditioner—significantly limits the widespread adoption of split-type air conditioners. For transient populations, the cost of dismantling and reinstalling 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 development 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 in which the outdoor unit extends out of the wall through a hole and is fastened to the inner wall, so that the installation of the outdoor unit is no longer dangerous, the cost is reduced, and users can even complete it themselves; and 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 fixed to an interior wall includes a base, a bottom plate connected to the base and installed inside the wall, and a heat dissipation pipe assembly with a cooling fan. The heat dissipation pipe assembly has fins and is connected to the base. Adjacent heat dissipation pipes are connected end to end to form a series connection and have an interface. The above components constitute the outdoor unit. Except for the bottom plate, all parts can extend outdoors through holes in the wall. The matching indoor unit can be connected to the outdoor unit separately through pipes, or it can be connected to the bottom plate as a whole.

[0005] Furthermore, the base plate is also fixedly connected to a base plate fixing bracket, which can be fastened to the upper end beam of the wall above the window glass to bear the weight of the base, the heat dissipation pipe assembly and its contents, so that the base and the heat dissipation pipe assembly can extend outdoors through the window glass opening.

[0006] Furthermore, a compressor is also installed inside the base, which is connected to the heat dissipation pipe assembly interface to form an outdoor unit of the air conditioner condenser, and the heat dissipation pipe assembly forms a condenser pipe assembly.

[0007] Furthermore, the base is separated from the heat dissipation pipe assembly and connected by a bottom hinge to form a foldable structure. After the heat dissipation pipe assembly extends out of the wall, it can hang down along the hinge under its own weight. The compressor and the heat dissipation pipe assembly are connected by a high-pressure hose.

[0008] Furthermore, a fixing device is provided at the farthest end of the heat dissipation pipe assembly, which can be rigidly fixed to the wall.

[0009] Furthermore, the indoor unit of the air conditioner is connected to the base plate to form a whole, and the evaporator pipe of the indoor unit is fixedly connected to the corresponding pipe of the outdoor unit, forming a whole unit.

[0010] Furthermore, an air duct assembly is provided at the air outlet of the indoor unit of the integrated air conditioner. The air duct assembly is equipped with a connecting mechanism to achieve corner connection and arbitrary extension through the air duct. The air duct is provided with an air outlet, and some sections are provided with corrugated telescopic for length adjustment. The end of the air duct is connected to the port of the connecting mechanism.

[0011] Furthermore, a relay fan is installed in the air duct assembly connection mechanism of the integrated air conditioner, and a power supply line for the fan is laid.

[0012] Furthermore, each relay fan in the air duct assembly connection mechanism of the integrated air conditioner is equipped with a remote control device to control the start / stop and fan speed of each fan.

[0013] Furthermore, when applied to portable air conditioners, to eliminate the cumbersome air-cooled exhaust pipes, a water-cooled mode is adopted. The traditional air-cooled condenser is replaced with a water-cooled condenser, and a circulating water pump and a return water tank are added. A water-cooled outdoor unit is installed outdoors. The inlet of the heat dissipation pipe assembly of the water-cooled outdoor unit is connected to the aforementioned circulating water pump through the supply pipe of the cooling water pipe, and the outlet of the heat dissipation pipe assembly is connected to the inlet of the water-cooled condenser. The outlet of the water-cooled condenser leads to the return water tank. The difference from the aforementioned air conditioner outdoor unit is that the heat dissipation pipe assembly flows with cooling water instead of refrigerant. The heat dissipation pipes only need to withstand normal pressure, and aluminum pipes can be used to reduce weight and lower costs.

[0014] Compared to existing technologies, the air conditioner and water-cooled outdoor unit that are securely fixed in a wall hole according to this utility model have the following advantages: the weight of the outdoor unit is borne by the entire wall rather than the outer wall surface, ensuring reliable load-bearing and preventing detachment; during installation, only a round hole of appropriate size needs to be made in the wall, and then the entire outdoor unit or even the entire integrated unit is pushed into the wall hole from inside the room to extend outdoors, and the fastening work is completed on the inner wall, avoiding the dangers of working at height; the integrated unit eliminates the need for professional operations such as pipe connection, has high cooling efficiency, avoids refrigerant spillage, and can be installed independently; when applied to portable air conditioners, it greatly improves cooling efficiency.

Detailed Implementation

[0017] 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.

[0018] It should be noted that the terms "upper", "lower", "left", "right", "front", "back", "bottom", 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.

[0019] As shown in Figures 1 and 2, the outdoor unit consists of a base 1 supporting the air conditioner, a bottom plate 2 connected to the base and installed inside the wall, and a heat dissipation pipe assembly 3 with a cooling fan 32. The heat dissipation pipe assembly has fins for good heat dissipation (not shown) and is connected to the base 1. This embodiment uses an embedded process, and adjacent heat dissipation pipes 3 are connected end-to-end to form a series connection (the embedded part is not shown), with an inlet 33 and an outlet 34 (straight-through). These components constitute the outdoor unit. Except for the bottom plate, all parts can extend outdoors through holes in the wall to dissipate heat to the atmosphere. The heat dissipation pipes 3 are made of copper or aluminum pipes with good thermal conductivity, and in addition to heat dissipation, they also support the outdoor unit's structural components. The cooling fan 32 is shown in the figure. An axial flow fan or a cross-flow fan can be used, depending on the design requirements. For example, if the outdoor unit is relatively long and slender, a cross-flow fan is more advantageous. The outdoor unit is also equipped with a protective shell to prevent debris from accumulating and causing damage or affecting heat dissipation. Due to its simple structure, it will not be illustrated or described in detail. The outdoor unit can be made into a square shape with a square wall opening. This embodiment uses a circular shape because it is convenient to open the wall opening and facilitates the overall layout of the outdoor unit.

[0020] The matching indoor unit can include refrigeration components such as a compressor and expansion valve. The outdoor unit mentioned above only serves as a condenser. The compressor is connected to inlet 33 and outlet 34 through a pipe, and then connected to the expansion valve and evaporator of the indoor unit through another pipe to form a complete refrigeration system. The advantage of this solution is that the outdoor unit is simple, lightweight, and easy to maintain. The disadvantage is that the indoor unit is noisy and the compressor heats up indoors, affecting the refrigeration efficiency.

[0021] In the conventional mode, as shown in Figure 1, the compressor 11 is installed inside the base 1. The compressor and the heat dissipation pipe assembly are connected via a reserved internal interface to form a complete outdoor unit of the air conditioner condenser. The heat dissipation pipe assembly forms the condenser pipe assembly, with an inlet 33 reserved on the base plate 2 connected to the inlet of the compressor 11, and externally connected to the conventional indoor unit of the air conditioner via a pipeline. The outlet of the compressor 11 is connected to one end of the heat dissipation pipe assembly interface, and the other interface of the heat dissipation pipe assembly is connected to outlet 34 (straight-through), and then connected to the expansion valve of the indoor unit of the air conditioner via another pipeline to form a complete refrigeration system. To minimize noise and vibration, vibration damping measures are taken between the compressor 11 and the base 1, which will not be detailed here. The compressor is a horizontal type (rotary vane type or scroll type).

[0022] As shown in Figure 2, the base plate 2 is fastened to the inner wall by fasteners 21 at the four corners. The fasteners 21 can be bolts or expansion screws.

[0023] 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 exterior wall to install an external bracket. The load-bearing position is in the wall hole and the interior wall, and then distributed to the wall, which greatly improves the reliability. The entire installation process only requires the outdoor unit to be extended outside through the wall hole, and then fastened to the interior wall with fastener 21.

[0024] To prevent the outdoor unit from protruding too much from the exterior wall, which would be unsightly and violate certain regulations, as shown in Figure 3, a heat dissipation pipe assembly 3 is added with a heat dissipation pipe assembly base 35. Each heat dissipation pipe is embedded in it and two pipe interfaces 36 are left out. It is connected to the base 1 through the bottom hinge 14 to form a foldable structure. After the heat dissipation pipe assembly part protrudes from the wall, it can hang down along the hinge 14 under its own weight. The outlet of the compressor 11 is connected to one of the heat dissipation pipe interfaces 36 through a high-pressure hose. The other end of the interface 36 is connected to the outlet 34 through a high-pressure hose. A corrugated pipe is fitted between the heat dissipation pipe assembly base 35 and the base 1 as a protective sleeve. After folding, the corrugated pipe folds and unfolds to form a protective cover (not shown). To prevent the suspended heat dissipation pipes from swaying due to strong winds, which could cause the hinges to fatigue and detach, it is necessary to rigidly fix them. As shown in the figure, a fixing end 37 is set at the farthest end of the heat dissipation pipes. The fixing bolt 23 passes through the small hole opened at the corresponding position in the wall 4 and is fixed by passing through the matching threaded hole opened in the fixing end 37. At the same time, the fixing bolt 23 is also fixed on the inner side of the wall (not shown in the figure). In order to facilitate the alignment of the fixing bolt 23 with the matching threaded hole opened in the fixing end 37, a flared mouth can be set around the threaded hole of the fixing end 37 (not shown in the figure). As shown in Figure 4, the main structure of the indoor unit 5 is connected to the base plate 2 to form an integral unit. The evaporator pipe of the indoor unit is fixedly connected to the corresponding pipe of the outdoor unit (not shown), and the whole unit becomes an integral unit. During installation, the outer casing of the indoor unit 5 is first removed, and the whole unit is moved to the wall opening. The outdoor unit is then aligned with the wall opening and pushed out until the base plate 2 is against the inner wall. It is then fastened to the inner wall with fasteners 21, and the outer casing of the indoor unit 5 is then reinstalled. In this embodiment, the indoor unit 5 is vertical, which is suitable for situations where the wall opening is in the middle of the wall. The air outlet 51 is positioned as high as possible to facilitate the diffusion of cold air in the room.

[0025] As shown in Figure 5, the indoor unit 5 of the air conditioner adopts a horizontal layout similar to that of a traditional indoor unit, which is suitable for situations where the wall opening is located near the top of the wall. The rest of the structure is basically the same as the previous embodiment, and will not be described again. The condensate water generated by the indoor unit can be treated in the same way as that of a window air conditioner, either by leading it out to the outside through pipes or by splashing it onto the condenser for evaporation, and will not be described again.

[0026] For situations where it is difficult to create openings in the wall, this can be solved by creating openings in the window glass. As shown in Figure 6, a round hole of appropriate size is made in the window glass 41, and an elastic material is fitted into the hole to form a sealing ring 42, which serves to seal and prevent the transmission of noise and vibration. Since the window glass cannot bear weight, the base plate 2 is fixed to the upper beam of the wall 4 by fasteners 21 through the base plate fixing bracket 22, and the indoor unit 5 is also fixed to the left wall. The horizontal layout of the air conditioner indoor unit shown in the figure is only for illustrative purposes. This mode is also applicable to any other structure. The base plate 2 can also be directly extended to replace the base plate fixing bracket 22, as shown in Figure 7. The vertical layout of the air conditioner indoor unit can be directly fixed to the upper beam of the wall 4 above the window glass opening without the need for the base plate fixing bracket 22. The exposed part of the base 1 on the inside of the window glass can be covered with sound insulation and heat insulation foam, which is not shown in the figure.

[0027] For the heat dissipation pipe assembly in the through-window glass installation mode, a thin metal plate can be used to make the component. One end is fixed to the gap of the openable window sash, and the other end is fixed to the threaded hole 37 at the fixing end (not shown in the figure). Alternatively, the component can be fixed to the window frame, and the fixing operation can be carried out through the openable window sash.

[0028] The indoor and outdoor units of the integrated air conditioning unit are connected as a whole. The installation position of the indoor unit is inevitably limited by the wall opening, and the air outlet may not be in an ideal position. To solve this problem, as shown in Figure 8, an air duct assembly 6 is set at the air outlet of the indoor unit 5. The air duct assembly is equipped with a connecting mechanism 61 to realize corner connection and arbitrary extension. The air duct 62 is equipped with several air outlets for cold air to enter the indoor space (not shown), and some sections are equipped with corrugated telescopic for length adjustment (not shown). The end of the air duct 62 is connected to the port of the connecting mechanism 61, and a sealing head is set at the end (not shown).

[0029] The air duct connection mechanism 61 of the integrated air conditioner can be a three-way structure as shown in the figure, or it can be a corner structure. A relay fan is installed in the connection mechanism 61, and a fan power supply line (not shown) is laid.

[0030] Each relay fan in the air duct assembly connection mechanism 61 of the integrated air conditioner is equipped with a remote control device to independently control the start and stop and wind speed of each fan, so as to adjust the air volume at each position in the room to make the temperature reach a comfortable value. The air duct assembly can even cross rooms, so that one air conditioner can benefit two rooms.

[0031] The air duct system ensures even airflow throughout the room, allowing for customized air distribution and avoiding the problem of excessively cold airflow when the indoor unit is directly facing the air outlet, a common issue with traditional indoor units.

[0032] 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 and unsightly, and their cooling efficiency is also greatly reduced. To solve these problems, it is necessary to modify them to be water-cooled. Water-cooled outdoor units are lightweight and easy to install, causing little trouble during installation, while greatly improving cooling efficiency. The small cooling water pipes are also easy to lay out.

[0033] As shown in Figure 9, the structure of the portable air conditioner's water-cooled outdoor unit is basically the same as the outdoor unit described above. The difference is that instead of refrigerant, cooling water flows inside the heat dissipation pipe assembly. The heat dissipation pipes only need to withstand normal pressure, and aluminum pipes can be used to reduce weight and cost. The portable air conditioner's main 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 pipe is divided into a supply water pipe and a return water pipe. 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, where it flows back and forth inside the heat dissipation pipe assembly 3. After being cooled by the cooling fan 32, the water is sent from the outlet nozzle 34 through the return water pipe in the cooling water pipe to the inlet of the water-cooled condenser to be cooled to high temperature. 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 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.

[0034] Portable air conditioner water-cooled outdoor units are very lightweight because they do not have a compressor and use aluminum tubes for heat dissipation. When it is inconvenient to drill holes in the wall, they can be installed by drilling holes in the window glass.

[0035] 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.

[0036] 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.
