Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment, and more specifically, to an outdoor air conditioning unit and an air conditioning system. Background Technology

[0002] Existing air conditioner outdoor units include compressors, low-pressure tanks, electrical components, filters, check valves, oil separators, and capillary tubes. All components need to be connected through connecting pipes. The compressor vibrates during operation, while the low-pressure tank and connecting pipes do not vibrate. The connection between vibrating and non-vibrating components will generate stress. The pipes will shake during transportation, resulting in noise and pipe wear.

[0003] To avoid pipe rubbing issues caused by contact between pipes, a minimum gap must be maintained between the pipes. Furthermore, during pipe welding, the welding torch needs to be inserted into the space enclosed by the condenser. During installation, a gap must also be reserved for inserting the coil. Therefore, a minimum operable space must be reserved between the pipes, with the minimum being that a fist can fit inside. At this point, the entire internal space of the outdoor unit is filled with pipes, resulting in complex piping and high installation and maintenance costs. Summary of the Invention

They are only for the convenience of describing this invention and simplifying the description, 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, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0052] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0053] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0054] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0055] Firstly, this application provides an outdoor unit for an air conditioner, such as... Figure 1 and Figure 2 As shown, it includes a shell, a partition 1, a circulating power unit, and a piping assembly 3; the shell has a receiving cavity; the partition 1 is disposed in the receiving cavity and divides the receiving cavity into a first chamber and a second chamber; the circulating power unit and the piping assembly 3 are both disposed in the first chamber; the piping assembly 3 is connected to the circulating power unit and is used to realize the connection and closure of all the connecting pipes of the circulating power unit.

[0056] In this embodiment, the housing includes a base 6, a shell plate, and a top plate. The base 6 is used to support the internal equipment and devices of the housing. The shell plate surrounds the edge of the upper surface of the base 6, and the top plate covers the shell plate, together forming a complete whole as the housing.

[0057] Since the main body of the shell is formed by shell plates, an internal cavity is formed, and other equipment is placed inside the cavity.

[0058] Specifically, the partition 1 is vertically installed in the receiving cavity, dividing the receiving cavity into two chambers, namely the first chamber and the second chamber. The circulating power unit and the piping integration block 3 are both installed in the first chamber. The piping integration block 3 integrates all the fittings on the connecting pipes of the circulating power unit together, so as to adjust and control the connection and closure status of each pipe of the circulating power unit.

[0059] Specifically, in this embodiment, the partition 1 is provided with a vent hole 8, so that the first chamber and the second chamber can be connected through the vent hole 8, which avoids excessive heat generated by the circulating power device during operation, which would cause the temperature in the first chamber to be too high, thus ensuring the normal operation of the entire outdoor unit of the air conditioner.

[0060] In this embodiment, all the fittings on the connecting pipelines are integrated together, which avoids mutual interference during pipeline laying, reduces the difficulty of assembly, improves assembly efficiency, and also facilitates the installation and maintenance of equipment inside the housing, such as the circulating power unit.

[0061] Specifically, in this embodiment, the piping integration block 3 is located above the circulating power device, which makes full use of the space. It is not necessary to lay both the circulating power device and the piping integration block 3 flat on the base 6, thus avoiding increasing the area of ​​the base 6 and wasting the space above the circulating power device, thereby improving the space utilization rate.

[0062] In this embodiment, the circulating power unit includes a low-pressure tank 4 and a compressor 5, which are respectively connected to the piping integration block 3.

[0063] Specifically, in this embodiment, the piping integration block 3 is located above the low-pressure tank 4 and the compressor 5. The pipelines connecting the low-pressure tank 4 and the compressor 5 to other equipment extend upwards and connect with the piping integration block 3. The piping integration block 3 is used for on / off control and gas-liquid filtration, etc.

[0064] Specifically, in this embodiment, the position of the piping assembly 3 can be flexibly adjusted according to its volume. Since the low-pressure tank 4 and compressor 5 have different heights, when the piping assembly 3 is smaller, it only needs to be placed above the device with the lower height between the low-pressure tank 4 and compressor 5; when the piping assembly 3 is larger, it needs to be placed above both the low-pressure tank 4 and compressor 5.

[0065] In a preferred embodiment of the present invention, the circulating power unit is placed on the housing, and the piping assembly 3 is placed on the partition 1.

[0066] Specifically, in this embodiment, since the weight and volume of the circulating power device are relatively large, fixing the circulating power device on the base 6 can ensure the stability of the circulating power device during installation and transportation.

[0067] In this embodiment, the circulating power device is installed on the base 6 by means of bolts for fixed connection.

[0068] It should be noted that the fixed connection method of the circulating power device on the base 6 can be bolt connection, but it is not limited to bolt connection. It can also be other fixed connection methods, such as snap-fit, welding, riveting, etc. In other words, as long as the circulating power device can be fixedly installed on the base 6 and the stability of the circulating power device on the base 6 can be guaranteed, it is acceptable.

[0069] To further improve the installation stability of the circulating power unit, the circulating power unit can be connected to both the base 6 and the partition 1 simultaneously to ensure the installation stability of the circulating power unit.

[0070] The piping assembly 3 is relatively small in size and weight. By fixing it on the partition 1, the overall space can be fully utilized and the space utilization rate can be improved.

[0071] Specifically, the piping assembly 3 is fixedly installed on the partition 1 by means of a connector connecting the piping assembly 3 to the partition 1.

[0072] There are many ways to set up the connector. For example, bolts can be used as connectors to thread the piping assembly 3 to the partition 1; ropes can be used as connectors to bind the piping assembly 3 to the partition 1; or a snap-fit ​​structure can be used as the connector to snap the piping assembly 3 to the partition 1 to achieve the connection. In other words, the fixed connection method between the piping assembly 3 and the partition 1 is not limited to any of the above methods, as long as it can fix the piping assembly 3 to the partition 1.

[0073] Specifically, in a preferred embodiment of the present invention, the connector includes a connecting plate 10; one end of the connecting plate 10 is fixedly disposed on the partition plate 1, and a connecting groove is provided on the connecting plate 10, and the piping integration block 3 is connected to the connecting plate 10 through the connecting groove.

[0074] Specifically, the connector is used to connect the piping assembly 3 to the partition 1, so the structure of the partition 1 needs to be adjusted according to the specific form of the connector.

[0075] In this embodiment, as Figure 3 As shown, one end of the connecting plate 10 is fixedly disposed on one side of the partition 1. Specifically, an installation groove 101 is provided on the partition 1, and one end of the connecting plate 10 has a certain bend. By placing the bent part in the installation groove 101, it is fixedly connected to the partition 1 by bolts, so as to achieve the purpose of fixing the connecting plate 10 to the partition 1.

[0076] Specifically, in this embodiment, the number of bolts is at least two, in order to prevent the connecting plate 10 from rotating around the bolts, thus ensuring the stability of the installation state of the connecting plate 10.

[0077] Specifically, in this embodiment, the mounting groove 101 enables the mounting and positioning of the connecting plate 10 on the partition 1, facilitating the installation of the connecting plate 10 on the partition 1.

[0078] Specifically, in this embodiment, the connection between the connecting plate 10 and the partition plate 1 is fixed by the bolt connection method described above, but it is not limited to bolt connection. It can also be other methods, such as welding, riveting, snap-fitting, etc. In other words, as long as one end of the connecting plate 10 can be fixedly set on the partition plate 1, it is acceptable.

[0079] In this embodiment, at least one connecting groove is provided on the upper surface of the connecting plate 10. The protruding pipe 301 extending from the inside of the piping assembly block 3 passes through the connecting groove, so that the protruding pipe 301 is connected to the connecting plate 10 through the connecting groove. The connecting plate 10 can support the protruding pipe 301, and further support the piping assembly block 3.

[0080] Specifically, in this embodiment, the shape of the connecting groove can be a rectangular groove, a semi-circular groove, or a groove structure of other shapes, as long as the protruding tube 301 can pass through the connecting groove to realize the connection between the connecting plate 10 and the protruding tube 301.

[0081] Specifically, in this embodiment, there are at least two connecting slots. The arrangement of two connecting slots ensures that the support provided to the piping assembly block 3 has good balance.

[0082] In this embodiment, the number of connecting plates 10 can be one or more. For example, when there are two connecting plates 10, they can be set on opposite sides of the piping assembly block 3 to improve the balance of the connecting plates 10 when supporting the piping assembly block 3.

[0083] In this embodiment, the connection between the connecting groove and the protruding pipe 301 can be a simple support connection, or it can be a snap-fit ​​or transition fit to further increase the connection strength between the connecting plate 10 and the piping integration block 3, thereby ensuring the connection stability between the two.

[0084] In a preferred embodiment of the present invention, a positioning plate 11 is provided on the protruding pipe 301 of the piping integration block 3, the protruding pipe 301 passes through the mounting groove, and the positioning plate 11 is connected to the connecting plate 10.

[0085] Specifically, due to the support relationship between the connecting groove and the protruding pipe 301 on the piping assembly block 3, there is only vertical support. In the horizontal direction, only the side wall of the connecting groove positions the protruding pipe 301 radially, but there is no axial positioning of the protruding pipe 301, which makes the stability of the piping assembly block 3 on the connecting plate 10 insufficient.

[0086] To solve the above problems, a positioning plate 11 is provided on the protruding pipe 301 of the piping assembly block 3. The positioning plate 11 is attached to the connecting plate 10, and then the positioning plate 11 and the connecting plate 10 are fixedly connected together by bolts or other means, thereby realizing the axial positioning of the protruding pipe 301.

[0087] Specifically, in this embodiment, the positioning plate 11 and the extension tube 301 are fixedly connected.

[0088] More specifically, there are many ways to fix the connection, such as snap-fit, interference fit, welding, threaded connection, etc. In other words, as long as it can fix the positioning plate 11 on the protruding tube 301, it is acceptable.

[0089] In this embodiment, the connection between the positioning plate 11 and the connecting plate 10 can be fixed by bolts, but it is not limited to bolt connection. Other fixed connection methods are also possible, such as welding, riveting, snap-fitting, etc. In other words, as long as the positioning plate 11 and the connecting plate 10 can be fixedly connected to achieve axial positioning of the protruding tube 301, it is acceptable.

[0090] In this embodiment, a positioning plate 11 is provided on each protruding tube 301.

[0091] In a variable implementation, each protruding tube 301 may be provided with two positioning plates 11, the gap between the two positioning plates 11 being equal to the thickness of the connecting plate 10, thereby achieving axial positioning of the protruding tube 301 on the connecting plate 10 through the two positioning plates 11.

[0092] It should be noted that in this embodiment, the positioning plate 11 on each protruding tube 301 can be set in the same way or in different ways; similarly, when each positioning plate 11 is fixedly connected to the connecting plate 10, its connection method can be the same or in different ways.

[0093] In a preferred embodiment of the present invention, an electrical control box 2 is connected to the piping integration block 3.

[0094] Specifically, in this embodiment, the electrical control box 2 is connected to the piping integration block 3. The electrical control box 2 is supported by the connecting pipes on the piping integration block 3, and some pipes of the piping integration block 3 are connected to the electrical control box 2. The electrical control box 2 realizes the functional control of some pipes.

[0095] In this embodiment, the electrical control box 2 is used to control the various devices of the outdoor unit of the air conditioner.

[0096] In a preferred embodiment of the present invention, such as Figures 4-7 As shown, the piping assembly 3 includes a body 302; the body 302 integrates at least one of the following devices: a one-way valve 305, an oil separator 304, a filter 303, and a four-way valve 9; the body 302 is provided with at least one channel 306 for fluid flow, one end of the channel 306 is connected to a device, and the other end of the channel 306 is used to connect to other devices outside the body 302.

[0097] In this embodiment, the main body 302 of the piping manifold 3 can integrate only one of the following devices: check valve 305, oil separator 304, filter 303, and four-way valve 9; or any two or three of these devices; or even all four. The integration of different devices is simply a matter of needing to streamline the piping, facilitate its layout, and prevent interference between the piping and other equipment or devices.

[0098] In this embodiment, when integrating various devices, the piping integration block 3 can integrate only one or multiple devices, depending on the specific number required in the actual application. For example, when the piping integration block 3 integrates only a one-way valve 305, it can integrate one one-way valve 305 or multiple one-way valves 305; when the piping integration block 3 integrates a one-way valve 305 and an oil separator 304, the number of both the one-way valve 305 and the oil separator 304 can be one, or the number of one one-way valve 305 and multiple oil separators 304, or multiple one-way valves 305 and one oil separator 304, or multiple one-way valves 305 and multiple oil separators 304; and so on, when the piping integration block 3 integrates more types of devices.

[0099] Specifically, in this embodiment, when various devices are integrated, they need to be connected to the outside through a conduit. In this embodiment, the conduit connected to the outside is channel 306. One end of channel 306 is connected to the external extension tube 301, and the other end of channel 306 is connected to the integrated device.

[0100] In a preferred embodiment of the present invention, such as Figures 8-13 As shown, the piping assembly 3 includes a body 302; the body 302 integrates at least one of the following devices: a one-way valve 305, an oil separator 304, and a filter 303; the body 302 is provided with at least one channel 306 for fluid flow, one end of the channel 306 is connected to a device, and the other end of the channel 306 is used to connect to other devices outside the body 302; a four-way valve 9 is integrated on the outside of the body 302, and the four-way valve 9 is connected to the device inside the body 302 through the channel 306.

[0101] As can be seen from the above, the difference between the piping integration block 3 in this embodiment and the piping integration block 3 in the previous embodiment is that the integration position of the four-way valve 9 is different.

[0102] Because the four-way valve 9 is relatively large in size and occupies a relatively large space, integrating the four-way valve 9 into the piping assembly block 3 will significantly increase the size of the piping assembly block 3 and increase its space occupancy.

[0103] After the four-way valve 9 is placed externally, other components are integrated to form the piping assembly block 3, which is then connected to the four-way valve 9. This effectively reduces the space occupied by the overall piping assembly block 3 and improves space utilization.

[0104] In a preferred embodiment of the present invention, the main body 302 is provided with an extension tube 301, one end of the extension tube 301 is used to communicate with other devices, and the other end of the extension tube 301 is connected to the channel 306.

[0105] Specifically, in this embodiment, each of the devices integrated inside the body 302 needs to have at least one channel 306 that communicates with other external devices, and each channel 306 has an extension tube 301 at its outer end to facilitate communication between the channel 306 and other devices or components.

[0106] Specifically, each protruding tube 301 is a through tube, which can connect the device in the piping assembly 3 to a device or a single device.

[0107] It should be noted that one end of the protruding tube 301 is connected to the channel 306, and the other end can be connected to one device or multiple devices, as long as it can achieve the required functions of the device.

[0108] In a preferred embodiment of the present invention, the protruding pipe 301 provided on the same side of the piping assembly block 3 is flush with the end away from the channel 306.

[0109] In this embodiment, the outer ends of all the protruding pipes 301 on the same side of the piping integration block 3 are aligned, which facilitates the connection and installation of each protruding pipe 301. At the same time, it can effectively avoid interference between the protruding pipes 301 when they are connected, and also avoid interference when other devices install and connect the protruding pipes 301.

[0110] It should be noted that the protruding tube 301 on the same side can be flush or not flush depending on the actual installation position.

[0111] In a preferred embodiment of the present invention, a portion of the inner wall of the second chamber is a heat exchanger 7, and the heat exchanger 7 is connected to the piping assembly block 3.

[0112] In this embodiment, the heat exchanger 7 removes the heat generated in the first chamber through heat exchange, thereby reducing the impact of heat generation on the various devices in the first chamber.

[0113] Specifically, some of the shell plates are replaced by heat exchangers, that is, the plate-shaped heat exchangers work together with the shell plates to form a second cavity inside.

[0114] Specifically, in this embodiment, the heat exchanger 7 is used as part of the inner wall of the second chamber, which can reduce the number of shell plates used, increase the internal space of the second chamber, or reduce the overall volume of the outdoor unit of the air conditioner, thereby improving the space utilization rate.

[0115] Specifically, in this embodiment, a fan is also provided in the second chamber, and an air inlet and an air outlet are provided on the shell. The air inlet is located on the top plate, and the air outlet is located on the shell plate, so that the exhaust direction of the fan is on the side of the shell.

[0116] Specifically, in this embodiment, since the side surface area is large when exhausting air from the side of the shell, the number of exhaust blades provided on the shell plate is two.

[0117] Secondly, this application also provides an air conditioning system that includes an outdoor unit of any of the above-mentioned air conditioning systems.

[0118] Specifically, in this embodiment, the main circulation process of the outdoor unit of the air conditioner is as follows:

[0119] The gas flows from the return pipe into the low-pressure tank 4, then from the low-pressure tank 4 into the compressor 5. After being discharged from the compressor 5, it enters the oil separator 304 of the piping assembly 3, then through the one-way valve 305 of the piping assembly 3 into the four-way valve 9, and then through the four-way valve 9 into the heat exchanger 7. After heat exchange in the heat exchanger 7, the gas flows into the electrical control box 2. After being cooled by the electrical control box 2, it flows through the electronic expansion valve and the adapter into the indoor unit heat exchanger. After being discharged from the indoor unit heat exchanger, it flows through the meter connector into the filter 303 of the piping assembly 3 for filtration, and finally returns to the low-pressure tank 4 through the four-way valve 9, completing a complete flow loop.

[0120] The beneficial effects of the embodiments of the present invention are:

[0121] By integrating all the connecting pipes of the circulating power unit onto the piping integration block 3, the piping is streamlined, the piping layout is reduced, interference with the equipment inside the shell is avoided, and the installation and maintenance of the equipment inside the shell is facilitated. The circulating power unit and the piping integration module are both located in the second cavity, thereby effectively improving the space utilization rate.

[0122] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
