Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a module mechanism, an air conditioner outdoor unit and an air conditioning system. Background Art

[0002] An air conditioner is a heat exchange device, typically consisting of a compressor, condenser, one-way valve, four-way valve, capillary tube, electrical components, and an oil separator. The compressor's exhaust passes through the oil separator and one-way valve into the four-way valve, where it flows sequentially to the condenser and evaporator, returning to the compressor. Each component requires connecting piping. The compressor vibrates during operation, while the low-pressure tank and connecting piping remain stationary. This creates stress between the vibrating and non-vibrating components, and the piping can vibrate during transportation, causing noise and wear.

[0003] In order to solve the above problems, some technologies integrate some functional components of the air conditioner to form a modular structure. A cavity is formed inside the modular structure to replace the pipeline. At the same time, condensers, one-way valves and other components are integrated in some cavities to reduce the number of pipelines and reduce pipeline vibration and pipeline wear.

[0004] Some existing modular mechanisms include two metal plates that snap together to form a cavity between the two plates. A portion of the cavity serves as a flow path, replacing the pipeline, while another portion incorporates a valve body and other structures. However, when using existing modular mechanisms for air conditioning and cooling, the high-temperature, high-pressure gas from the compressor exhaust port flows through the oil separator, a one-way valve, and a four-way valve, or through pipelines connecting these components. Some pipelines carry a high-temperature medium, while others carry a low-temperature medium. Consequently, heat conduction occurs between the pipelines carrying the high-temperature medium and the pipelines carrying the low-temperature medium, causing a large amount of heat to be transferred from the high-temperature pipeline to the low-temperature pipeline. This results in heat loss and waste, significantly reducing the cooling efficiency of the air conditioning unit. Summary of the Invention

[0005] (1) The technical problem to be solved by the present invention is that the modular structure of the existing air-conditioning outdoor unit has a high-temperature flow path and a low-temperature flow path adjacent to each other, and a large amount of heat is transferred from the high-temperature pipe to the low-temperature pipe, resulting in heat loss and waste, which in turn leads to a decrease in the cooling energy efficiency of the air-conditioning unit.

[0045] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] like Figures 1 to 10 As shown, an embodiment of one aspect of the present invention provides a modular mechanism 1, comprising: a first module assembly 11 and a second module assembly 12 spaced apart from each other; the first module assembly 11 comprises a first plate 111 and a second plate 112, the first plate 111 and the second plate 112 being covered and connected to form at least one first accommodating cavity between the first plate 111 and the second plate 112; the second module assembly 12 comprises a third plate 121 and a fourth plate 122, the third plate 121 and the fourth plate 122 being covered and connected to form at least one second accommodating cavity between the third plate 121 and the fourth plate 122; the first accommodating cavity is used for circulating a high-temperature medium, and the second accommodating cavity is used for circulating a low-temperature medium.

[0047] The modular mechanism 1 provided in this embodiment divides the modular mechanism 1, which is originally a single plate body, into a first modular assembly 11 and a second modular assembly 12, which are spaced apart from each other. The first modular assembly 11 forms at least one first accommodating cavity, which serves as a channel for the circulation of refrigerant or as a accommodating cavity for a valve body (a one-way valve, an oil separator, or a filter). The second modular assembly 12 also forms at least one second accommodating cavity, which can also serve as a channel for the circulation of refrigerant or as a accommodating cavity for a valve body. The modular mechanism 1 integrates the pipes or valve bodies in the air conditioning system into a whole, thereby reducing the number of exposed pipes and thus reducing pipe costs. At the same time, because the first modular assembly 11 and the second modular assembly 12 are independent and spaced apart from each other, there is almost no heat conduction between the first modular assembly 11 and the second modular assembly 12. The first modular assembly 11 circulates a high-temperature medium, while the second modular assembly 12 circulates a low-temperature medium (refrigerant). Therefore, the "low-temperature zone" and the "high-temperature zone" are separated, which can solve the problem of heat loss and waste caused by the high-temperature flow path and the low-temperature flow path being arranged adjacent to each other on the same module in the prior art.

[0048] According to one embodiment of the present invention, Figure 1 and Figure 3 As shown, the first module assembly 11 and the second module assembly 12 are spaced apart from each other in the front and back directions, and the projection of the first module assembly 11 on the plane where the second module assembly 12 is located at least partially overlaps with the second module assembly 12. In this embodiment, since the projections of the first module assembly 11 and the second module assembly 12 in the same direction overlap, the overall width of the first module assembly 11 and the second module assembly 12 is smaller than the width of an entire module mechanism 1 in the prior art. Therefore, the module mechanism 1 occupies less space in the horizontal direction, facilitating the installation and maintenance of other structures of the air conditioner outdoor unit. At the same time, it has better versatility, that is, it can be applied to large air conditioner units as well as smaller air conditioner units.

[0049] Optionally, in this embodiment, the first module assembly 11 and the second module assembly 12 are parallel to each other, and the first module assembly 11 and the second module assembly 12 arranged in parallel occupy a smaller space as a whole;

[0050] Preferably, in this embodiment, the projection of the first module component 11 on the plane where the second module component 12 is located overlaps with the second module component 12, that is, the shape and size of the first module component 11 and the second module component 12 are the same, which can reduce the number of molds and save costs.

[0051] It can be understood that in the above embodiment of the present application, the first module assembly 11 and the second module assembly 12 may only partially overlap. In this case, the first module assembly 11 and the second module assembly 12 are staggered in the front-to-back direction, which can also achieve the purpose of reducing the volume occupied by the module mechanism 1 in the width direction, thereby improving the versatility of the mechanism.

[0052] In another embodiment of the present application, the first module assembly 11 and the second module assembly 12 are located in the same plane. In this case, the first module assembly 11 and the second module assembly 12 are arranged side by side and spaced apart. Since the first module assembly 11 and the second module assembly 12 are spaced apart, heat loss and waste caused by heat conduction in the cold and hot flow paths can also be avoided. However, since the first module assembly 11 and the second module assembly 12 are located in the same plane, the width direction occupies a larger volume, which is not conducive to the modular structure 1 being applicable to various models of units.

[0053] According to one embodiment of the present invention, at least one first groove is formed on the first plate 111, and the first plate 111 and the second plate 112 are covered and connected so that the first groove forms the first receiving cavity. In this embodiment, the first groove on the first plate 111 is directly engaged with the second plate 112 to form the first receiving cavity.

[0054] According to another embodiment of the present invention, Figures 3 to 8 As shown, a first groove is provided on the first plate body 111 , and a second groove corresponding to the position of the first groove is provided on the second plate body 112 . The first groove and the second groove are sealed and connected to form a first accommodating cavity.

[0055] In the above embodiment of the present application, the first accommodating chamber is used to accommodate the first refrigeration accessory that circulates the high-temperature medium. The first refrigeration accessory is an accessory that has a gas-liquid transmission function and can realize other functions in the air-conditioning system; because the high-temperature and high-pressure refrigerant flowing out of the compressor 2 needs to pass through the oil separator and the one-way valve during the refrigeration process of the air conditioner outdoor unit, the first refrigeration accessory includes an oil separator and a one-way valve.

[0056] Optionally, in one embodiment of the present application, Figure 3 and Figure 4 As shown, there are two first accommodating chambers, which are a one-way valve chamber 113 and an oil separator chamber 114. The oil separator chamber 114 is connected to the one-way valve chamber 113. At this time, the first module assembly 11 only integrates the one-way valve chamber 113 and the oil separator chamber 114. The high-temperature and high-pressure refrigerant coming out of the compressor 2 passes through the oil separator and the one-way valve and then flows out through the four-way valve 5 to enter the outdoor heat exchanger 4 (condenser). Therefore, the high-temperature and high-pressure refrigerant only passes through the first module assembly 11.

[0057] In another embodiment of the present application, the first accommodating chamber is provided with a one-way valve chamber 113, that is, only one one-way valve chamber 113 is integrated on the first module assembly 11. At this time, the oil separator that also circulates the high-temperature refrigerant is not integrated in the module mechanism 1, and the purpose of separating the high-temperature flow path and the low-temperature flow path can also be achieved.

[0058] In another embodiment of the present application, the first accommodating chamber is provided with one, and in this case the first accommodating chamber is an oil separator chamber 114, that is, only one oil separator chamber 114 is integrated on the first module assembly 11. At this time, the one-way valve for circulating the high-temperature refrigerant is not integrated in the module mechanism 1, and the purpose of separating the high-temperature flow path and the low-temperature flow path can also be achieved.

[0059] In the above embodiment of the present application, a one-way valve core is installed inside the one-way valve chamber 113 , and a separation net is installed in the oil separator chamber 114 .

[0060] According to one embodiment of the present invention, at least one third groove is provided on the third plate body 121, and the third plate body 121 is covered and connected with the fourth plate body 122 so that the third groove forms the second accommodating cavity. After the third plate body 121 and the fourth plate body 122 are covered, the second accommodating cavity is formed between the fourth groove on the third plate body 121 and the fourth plate body 122.

[0061] According to another embodiment of the present invention, Figures 8 to 10 As shown, a fourth groove is provided on the fourth plate 122 , and the third groove is opposite to the fourth groove and corresponds one to one; the third groove is connected to the corresponding fourth groove to form the second accommodating cavity.

[0062] In the above embodiment of the present application, the second accommodating cavity is used to accommodate the second refrigeration accessory for circulating low-temperature medium; the second refrigeration accessory is an accessory with gas-liquid transmission function and can realize other functions in the air-conditioning system; because the low-temperature refrigerant flowing out of the compressor 2 needs to pass through two filters during the cooling process of the air conditioner outdoor unit, the second refrigeration accessory includes a first filter and a second filter cavity.

[0063] In one embodiment of the present application, Figure 3 、 Figure 4 and Figures 8 to 10 As shown, there are two second accommodating chambers, namely a first filter chamber 127 and a second filter chamber 128. In this case, the second module assembly 12 integrates the second filter chamber 128 and the first filter chamber 127. The low-temperature, low-pressure gaseous refrigerant that has passed through the air conditioner indoor unit heat exchange enters the first filter chamber 127 and the second filter chamber 128, and is filtered and then returned to the low-pressure tank 3. Therefore, the low-temperature refrigerant only passes through the second module assembly 12.

[0064] In another embodiment of the present application, only one filter chamber is provided in the second accommodating chamber. In this case, only one filter chamber is provided on the second module assembly 12. This can also achieve the purpose of filtering the return refrigerant while blocking the heat exchange between the cold and hot flow paths. A filter assembly is installed in the filter chamber to achieve the filtering function.

[0065] According to one embodiment of the present invention, Figure 3 and Figure 4 As shown, at least one flow passage is formed in the second module assembly 12; the flow passage is used to circulate the low-temperature medium; in this embodiment, by forming a flow passage in the second module assembly 12 to replace the external pipe, the number of external pipes can be reduced, thereby reducing costs; and in this application, the flow passage formed in the second module assembly 12 is also used to circulate the low-temperature medium; to avoid heat waste caused by contact between the hot and cold areas of the first module assembly 11 and the second module assembly 12.

[0066] In this embodiment, the flow passage can also be formed in three ways. One is that a groove is provided on the third plate 121. After the third plate 121 and the fourth plate 122 are connected, the groove on the third plate 121 directly forms the flow passage with the fourth plate 122; the second is that a groove is provided on the fourth plate 122. After the third plate 121 and the fourth plate 122 are connected, the groove on the fourth plate 122 directly forms the flow passage with the third plate 121; the last is that the third plate 121 and the fourth plate 122 are provided with grooves of corresponding number and relative position. At this time, the groove on the third plate 121 and the groove on the fourth plate 122 are connected and connected to form the flow passage.

[0067] Optional, such as Figure 3 and Figure 4 As shown, in this embodiment, the flow passage is used to connect the second accommodating cavity to the outer surface of the second module assembly 12, so that the second refrigeration accessory in the second module assembly 12 can be connected to the pipeline of the air conditioning system through the flow passage.

[0068] For example, the flow passages may include, but are not limited to, a first flow passage 123 , a second flow passage 124 , and a third flow passage 125 .

[0069] In some optional embodiments, such as Figure 3 and Figure 4As shown, the upper end of the first circulation passage 123 can be located in the middle of the second module assembly 12, and the lower end of the first circulation passage 123 extends to the lower edge of the second module assembly 12, forming a first channel opening at the lower edge of the second module assembly 12, and the first channel opening is connected to the outdoor heat exchanger 4 through an external pipe. A first channel hole is provided on the third plate body 121, and the first channel hole is connected to the electrical control box through an external pipe.

[0070] In some optional embodiments, such as Figure 3 and Figure 4 As shown, the second circulation passage 124 is arranged adjacent to the first circulation passage 123, and both ends of the second circulation passage 124 are located in the middle of the second module assembly 12, wherein two second channel holes are respectively provided on the third plate body 121 at both ends of the second circulation passage 124, one of the second channel holes is connected to the electric control box through an external pipeline, and the other second channel hole is connected to the indoor heat exchanger.

[0071] In some optional embodiments, such as Figure 3 and Figure 4 As shown, the lower end of the third flow passage 125 is located in the middle of the second module assembly 12, and the upper end of the third flow passage 125 extends to the upper edge of the second module assembly 12, forming a third channel opening at the upper edge of the second module assembly 12. The third channel opening is connected to the low-pressure tank 3 via an external pipeline. The third plate 121 is provided with a third channel hole connected to the lower end of the third flow passage 125. The third channel hole is connected to the third port 53 of the four-way valve 5 via an external pipeline. Providing multiple flow passages in the second module assembly 12 can reduce the number of external pipelines, thereby reducing the number of rubber blocks and pipe clamps used to secure the pipelines. This can save costs and improve production efficiency. Moreover, since the pipelines are integrated into the second module assembly 12, pipeline stress and vibration can be reduced, thereby reducing noise and reducing the risk of pipeline rupture.

[0072] In some optional embodiments, such as Figure 3 、 Figure 4 and Figure 8As shown, the second module assembly 12 is further provided with at least one branch passage 126, which can serve as a branch pipe and reduce the number of pipes in the air conditioning system. In this embodiment, a groove can be provided only on the third plate 121, or only on the fourth plate 122, or on both the third plate 121 and the fourth plate 122. After the third plate 121 and the fourth plate 122 are connected, a branch passage 126 is formed between the third plate 121 and the fourth plate 122. In this embodiment, multiple grooves are provided on each of the third plate 121 and the fourth plate 122. After the third plate 121 and the fourth plate 122 are sealed and connected, the multiple grooves on the third plate 121 and the multiple grooves on the fourth plate 122 are connected in a one-to-one correspondence, forming multiple branch passages 126.

[0073] According to one embodiment of the present invention, Figure 3 and Figure 4 As shown, the first module assembly 11 and the second module assembly 12 are connected by a fixing member. The first module assembly 11 and the second module assembly 12 can be connected as a whole by fixing members such as brackets, thereby improving the integration of the module mechanism 1 and ensuring the overall structural strength of the module mechanism 1.

[0074] Optional, such as Figure 3 and Figure 4 As shown, in this embodiment, the fixing member includes a first flanging mechanism provided on the edge of the first module assembly 11 and a second flanging mechanism provided on the edge of the second module assembly 12; the first flanging mechanism and the second flanging mechanism are fixedly connected to connect the first module assembly 11 and the second module assembly 12. In this embodiment, the first module assembly 11 includes a first plate 111 and a second plate 112, both of which are metal plates, and the first plate 111 and the second plate 112 are connected by welding. Similarly, the second module assembly 12 includes a third plate 121 and a fourth plate 122, both of which are metal plates, and the third plate 121 and the fourth plate 122 are connected by welding. Due to the provision of the first flanging mechanism and the second flanging mechanism, it is possible to ensure that the first module assembly 11 and the second module assembly 12 are spaced apart and connected as one. Preferably, in this embodiment, the first module assembly 11 and the second module assembly 12 can be connected by screw connection. Specifically, through holes are opened on the first flanging mechanism and the second flanging mechanism, and then the two are connected and fixed by screws. While meeting the structural strength of the module mechanism 1, it can also avoid the problem of heat waste caused by heat exchange between cold and hot flow paths.

[0075] like Figures 3 to 7As shown, the first flanging mechanism includes a first folding edge 1111 provided in the edge of the first plate body 111 and a second folding edge 1121 provided in the edge of the second plate body 112; optionally, a first folding edge 1111 is provided at both ends of the first plate body 111, and the first folding edge 1111 is perpendicular to the first plate body 111; a second folding edge 1121 is provided at both ends of the second plate body 112, and the second folding edge 1121 is perpendicular to the second plate body 112; when the first plate body 111 and the second plate body 112 are connected, the two second folding edges 1121 are located between the two first folding edges 1111, and both abut against the first folding edge 1111 on the corresponding side; the first folding edge 1111 and the second folding edge 1121 cooperate to play a positioning role.

[0076] like Figure 3 、 Figure 4 and Figures 8 and 9 As shown, the second flanging mechanism includes a third folding edge 1211 arranged in the edge of the third plate body 121 and a fourth folding edge 1221 arranged in the edge of the fourth plate body 122; optionally, both ends of the third plate body 121 are provided with a third folding edge 1211, and the third folding edge 1211 is perpendicular to the third plate body 121, and both ends of the fourth plate body 122 are provided with a fourth folding edge 1221, and the fourth folding edge 1221 is perpendicular to the fourth plate body 122. When the third plate body 121 is connected to the fourth plate body 122, the two fourth folding edges 1221 are located between the two third folding edges 1211, and both are in contact with the third folding edge 1211 on the corresponding side. The third folding edge 1211 and the fourth folding edge 1221 cooperate to play a positioning role.

[0077] Among them, when the first module assembly 11 is connected to the second module assembly 12, through holes are correspondingly provided on the two first folded edges 1111 and the two third folded edges 1211, and then the first module assembly 11 and the second module assembly 12 are connected and fixed by screws passing through the through holes and cooperating with nuts.

[0078] It should be noted that, in the present application, the first module assembly 11 and the second module assembly 12 can also adopt other connection methods. As long as the first module assembly 11 and the second module assembly 12 can be spaced apart and fixed to each other, the design concept of the present application can be realized and should fall within the scope of protection of the present invention.

[0079] In another aspect, an embodiment of the present invention further provides an air-conditioning outdoor unit, which includes a compressor 2, a condenser, a four-way valve 5, a low-pressure tank 3 and the module mechanism 1 provided in the above embodiment.

[0080] According to another embodiment of the present invention, an air conditioner is provided, including an air conditioner indoor unit and the air conditioner outdoor unit described in the above embodiment, and the specific connection relationship thereof is as follows.

[0081] The low-pressure tank 3 is connected to the compressor 2 through an external pipeline, and the compressor 2 is connected to the oil separator through an external pipeline. The oil separator is connected to the one-way valve, the one-way valve is connected to the first interface 51 of the four-way valve 5, and the second interface 52 of the four-way valve 5 is connected to the outdoor heat exchanger 4. The outdoor heat exchanger 4 is connected to the first flow passage 123, the first flow passage 123 is connected to the electrical control box, and the electrical control box is connected to the second flow passage 124. The second flow passage 124 is used to communicate with the air-conditioning indoor unit, and an expansion valve is provided between the first flow passage 123 and the second flow passage 124; the first filter connected to the air-conditioning indoor unit is connected to the fourth interface 54 of the four-way valve 5, the third interface 53 of the four-way valve 5 is connected to the third flow passage 125, and the third flow passage 125 is connected to the low-pressure tank 3; wherein, at least one of the first filter, the oil separator, the one-way valve, the first flow passage 123, the second flow passage 124 and the third flow passage 125 is a structure in the modular mechanism 1.

[0082] For example, when the air-conditioning system is in the cooling state, the first interface 51 of the four-way valve 5 is connected to the second interface 52, and the third interface 53 is connected to the fourth interface 54. The refrigerant is compressed by the compressor 2 and converted into a high-temperature and high-pressure gas. The refrigerant discharged from the compressor 2 passes through the oil separator and the one-way valve in sequence. The refrigerant discharged from the one-way valve enters the first interface 51 of the four-way valve 5 and enters the outdoor heat exchanger 4. After absorbing cold in the outdoor heat exchanger 4, it becomes a medium-temperature and high-pressure liquid. The refrigerant discharged from the outdoor heat exchanger 4 enters the electric control box through the first flow path 123, and then enters the second flow path from the electric control box. Path 124, the refrigerant passes through the expansion valve during the process of flowing from the first circulation path 123 to the second circulation path 124, and becomes a low-temperature, low-pressure liquid, and then enters the indoor heat exchanger through the second circulation path 124. After cooling, it becomes a low-temperature, low-pressure gas. The refrigerant discharged from the indoor heat exchanger enters the first filter, and after filtration, enters the fourth interface 54 of the four-way valve 5, and is discharged through the third interface 53 of the four-way valve 5, and then flows into the low-pressure tank 3 through the third circulation path 125. The refrigerant in the low-pressure tank 3 returns to the compressor 2 and then continues to circulate.
