Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning structures, and in particular to an air conditioning pipeline module and an air conditioning unit. Background Art

[0002] As people's living standards improve, household air conditioners have gradually shifted from meeting basic temperature regulation needs to meeting diversified and personalized body optimization needs. Traditional single-function air conditioners, such as equipment used only for cooling or heating, have been unable to meet users' high standards for comfort. In recent years, the market demand for air conditioning functions has gradually expanded, and a variety of functions have been added to enhance user experience, such as precise temperature control and dehumidification, reducing dryness in cooling mode, and soft and comfortable wind mode. Through these functions, air conditioners can not only adjust the indoor temperature, but also further improve the air quality and user comfort, which is in line with the pursuit of high-quality life by modern families.

[0003] However, in order to achieve these functions, the internal design of the air conditioner has to become more complicated. Taking temperature control and dehumidification as an example, its implementation usually requires adding multiple valves and optimizing the refrigerant flow path. This adds more pipeline components to the air conditioner's piping system, such as electronic expansion valves, solenoid valves, etc. If the valve body fails, the air conditioning system cannot operate normally. The maintenance cost of repairing these complex piping structures is high. During the fault diagnosis process, because the valve body is embedded in the internal unit, it is difficult to disassemble and assemble, and it takes a lot of time to disassemble and test, and it is also easy to damage the unit. Summary of the invention

[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0043] When the existing indoor unit adds the effect of temperature control and dehumidification, the piping structure inevitably becomes complicated. Once the valve body in the piping structure, such as the electronic expansion valve, solenoid valve, etc., has problems, the maintenance difficulty and cost are quite high.

[0044] In this regard, Figure 1 , 5 As shown, the present invention proposes an external air-conditioning pipe module, specifically comprising: a box body 10 and a valve assembly 8, the box body 10 is detachably mounted on the outside of the side of the indoor unit 2 of the air conditioner, specifically mounted on an end plate (or side plate) at one end face of the indoor unit 2, the valve assembly 8 is arranged in the box body 10, the valve assembly 8 specifically comprises a plurality of valves, and pipes connecting the valves, the valves are installed in the box body 10, the ends of the pipes connecting the valves extend from the opposite end faces of the box body 10 (in other embodiments, they can also be adjacent or non-adjacent side faces, which can be arranged according to actual needs), the pipes of the valve assembly 8 extend out of the end faces of the box body 10, wherein the end of the pipe located at one end face is provided with a joint for connecting to the outdoor unit of the air conditioner, and the end of the pipe located at the other end face is provided with a joint for connecting to the indoor unit 2.

[0045] By separately arranging the valve and piping structure used by the air conditioner to switch the operating mode outside the indoor unit and performing modular arrangement, disassembly and repair can be performed without using a welding gun during after-sales maintenance, which facilitates troubleshooting and repair.

[0046] In a specific embodiment, the box body includes a plurality of splicing bodies, each of which is connected into one piece by means of a snap buckle, a screw or a plug-in structure, wherein at least two or more splicing bodies are provided with a notch at the splicing edge, and the specific size and shape of the notch are adapted to the shape of the valve assembly pipeline. When the plurality of splicing bodies are assembled according to the predetermined position, the notches correspond to each other, and after splicing, a through hole is formed along the valve assembly pipeline.

[0047] In a further embodiment, the notch can be arranged at different splicing edges as required, for example, at the upper and lower splicing edges or the left and right splicing edges. Through this splicing method, the valve assembly or part of the pipeline can be positioned and fixed first, and then multiple splicing bodies are spliced ​​in sequence, and the valve assembly pipeline is covered or clamped in the box body, so as to facilitate subsequent inspection and maintenance. By splicing the box body with multiple splicing bodies and reserving a notch that can form a through hole at the corresponding splicing edge, the valve assembly pipeline can be more convenient to assemble or disassemble, and the installation and after-sales maintenance of the air conditioning pipeline module can be completed efficiently.

[0048] In a further embodiment, in order to make the connection between multiple splicing bodies firm and convenient to install, part of the edge of the splicing body can extend outward or inward to form a connecting edge, which is used to cover the edge of the adjacent splicing body when two or more splicing bodies are butted against each other. The length and width of the connecting edge can be designed according to the size requirements of the box body and the arrangement of the valve assembly pipeline. Corresponding screw holes are provided at the connecting edge and the edge position of the adjacent splicing body overlapping with it. During assembly, it is only necessary to align and fit the connecting edge with the corresponding edge of the adjacent splicing body, and a firm connection can be achieved by screwing in a screw (or using other fasteners) at the screw hole.

[0049] In a specific embodiment, Figure 1 As shown, the box body 10 includes a first splicing box 101, a second splicing box 102, a first splicing cover 111 and a second splicing cover 112. The overall shape of the first splicing box 101 is U-shaped, and a notch 12 is provided at one end for the valve assembly 8 to pass through or access, which is convenient for inserting the valve assembly 8 and performing basic positioning during initial installation. The other end and the front side of the first splicing box 101 are not closed yet, leaving space for subsequent assembly and pipe routing. Figure 2 , 4As shown, the second splicing box 102 covers the front side of the first splicing box 101 and the end with the notch 12, forming a relatively closed protective surface at the front side and the notch 12. The first splicing box 101 and the second splicing box 102 can also reserve a number of notches 13 at the position of the notch 12 according to the direction of the pipeline of the valve assembly 8. The size of the notch 13 matches the diameter of the pipeline to form a through hole 14, which can provide a fit or support for the pipeline after the cover is closed, and does not hinder the normal setting of the pipeline. Figure 1 , 3 As shown, the first splicing cover 111 and the second splicing cover 112 are symmetrically or complementary designed according to the structural features of the valve assembly 8 and the other end of the first splicing box 101. After being spliced ​​together, the two cover the other end of the first splicing box 101, and are both installed in a detachable and fixed manner, wherein four notches 13 are arranged on the splicing sides of the first splicing cover 111 and the second splicing cover 112, and the remaining sides are all provided with bent edges for connecting with the edges of the first splicing box 101 and the second splicing box 102, and at the same time, four corresponding notches 13 are arranged on the splicing sides of the second splicing cover 112 and the first splicing cover 111, and reinforcing edges are extended at the intervals between the notches to cover part of the splicing side of the first splicing cover 111, thereby improving the connection strength between the first splicing cover and the second splicing cover (in addition, screw holes can be provided so that the reinforcing edges can be directly connected to the first splicing cover 111, and at the same time, the support of the pipeline at the through hole is improved).

[0050] Through this structural design of splitting and splicing at the location where the pipeline is set, when the valve assembly 8 needs to be inspected or maintained, it is only necessary to remove the corresponding splicing box or splicing cover to quickly open the box body 10 and directly contact the internal pipeline and valve body, thereby achieving more efficient troubleshooting and parts replacement.

[0051] In a specific embodiment, Figure 2 , 4 As shown, the first splicing box 101 is provided with a plurality of notches 13 (specifically, the two notches 13 in the figure) along the edge of the notch 12 at one end where the notch 12 is provided, and the second splicing box 102 also has corresponding notches 13 reserved on the plate body covering the notch 12, which are opposite to the notches 13 on the first splicing box 101. When the two are assembled in place, these relative notches 13 form a plurality of through holes 14 that penetrate the pipe at the notch 12. Figure 1 , 3As shown, the edges where the first splicing cover and the second splicing cover are spliced ​​with each other are also provided with a plurality of notches 13 aligned with each other (specifically, they can be 4 notches 13 respectively arranged in the figure), and a plurality of through holes 14 for pipes to pass through are formed at corresponding positions after splicing, so as to cooperate with the first splicing box 101 and the second splicing box 102 in the overall structure, and provide corresponding channels and supports for each pipeline of the valve assembly 8, which not only ensures that the closed box body 10 remains compact and stable in appearance, but also brings convenience for subsequent maintenance and overhaul.

[0052] Combined with Figure 1 , the upper side plate and the lower side plate of the first splicing box 101 do not end after the corresponding installation position of the splicing cover, but continue to extend outward for a section. And at the end, a bending edge connected to the shell of the inner machine 2 is formed by a bending process. In this way, the air-conditioning pipe module can be more closely fitted or fixed to the shell of the inner machine 2 during installation, thereby enhancing the overall stability. The parts of the upper side plate and the lower side plate of the first splicing box 101 extending outside the box body 10 are arranged parallel to each other, forming a relatively open installation area between the two. It can provide a centralized and convenient layout position for each joint arranged on the valve assembly 8, which is convenient for docking with the external machine pipeline or other related components. In addition, since this part has extended outside the main structure of the box body 10, even if the joint needs to be disassembled, repaired or replaced later, there is no need to additionally disassemble the splicing cover or open the inside of the box body 10, which simplifies the operation process and effectively avoids interference with other parts of the valve assembly 8.

[0053] like Figure 2 , 5 6, a buckle 21 notch 12 is provided on the bent edge of the upper side plate (it can also be the lower side plate), a buckle 21 that can pass through the notch 12 of the buckle 21 is provided on the side of the inner unit 2, and a screw hole is provided on the bent edge, and a corresponding screw hole is also provided on the outer side of the inner unit 2. When installing, the box body 10 can be pre-fixed by the buckle 21 first, and then the entire box body 10 can be fixed by directly screwing the screws on the bent edge.

[0054] The joint of the valve assembly 8 located on the other side of the box body 10 is a pipe joint, and each of the pipe joints is provided with a matching pipe joint nut 84 .

[0055] In the specific structure shown in the drawings, the valve assembly 8 is provided with a plurality of pipe joints (shown as 4 in the figure) on the other end face of the box body 10, and each pipe joint is provided with a matching pipe joint nut 84. Through the cooperation of these pipe joints and the corresponding pipe joint nut 84, the pipeline of the air conditioner indoor unit 2 can be reliably fastened to the valve assembly 8, and a standardized thread or flange structure is usually adopted, which can effectively avoid the cumbersome procedures and potential safety risks brought by the welding operation. When disassembly and maintenance are required in the later stage, the corresponding pipeline can be quickly separated by loosening the nut, and other valve components will not be interfered with; combined with the modular design of the aforementioned box body 10, the valve assembly 8 or the pipeline can be disassembled, replaced or maintained without moving the welding gun, thereby significantly improving the convenience and efficiency of maintenance.

[0056] Combined with Figure 7 , 8 It can be seen that in a specific embodiment, the valve assembly 8 is provided with a connector E and a connector F on one side of the box body 10, and a connector A, a connector B and a connector C are correspondingly provided on the other side. Connected between the connector F and the connector A is a first pipeline, and a first solenoid valve 81 is arranged on the first pipeline to control the on-off of the pipeline. A second pipeline in the form of a branch is also led out between the first pipeline and the connector B. The connector E and the connector C are connected through a third pipeline, and a fourth pipeline is separated from the third pipeline and connected to the connector D. The first pipeline and the fourth pipeline are connected through a fifth pipeline, and an electronic expansion valve 83 is arranged on the fifth pipeline. When the working modes of the air conditioner (such as heating, cooling or dehumidification mode) are switched, the first solenoid valve 81 and the electronic expansion valve 83 are respectively responsible for the opening, closing or flow control of the corresponding pipeline, and cooperate with the connectors E, F, A, B, C, D, etc. to realize the efficient circulation of the refrigerant between the evaporator, the valve assembly 8 and the outdoor unit.

[0057] The specific cycle implementation example is as follows: the E port is the liquid pipe, the F port is the gas pipe, the A, B, C, and D ends are respectively connected to the evaporator components inside the unit, among which C and D correspond to capillaries or throttling sections, and A and B respectively enter the upper evaporator 71 and the lower evaporator 72 for heat exchange.

[0058] When the unit is in cooling mode, the first solenoid valve 81 and the second solenoid valve 82 are opened at the same time, and the electronic expansion valve 83 is closed. After the liquid refrigerant enters the internal pipeline of the valve assembly 8 through the E port, it enters the evaporator through the C and D terminals, is converted into a gaseous refrigerant in the evaporator, returns to the valve assembly 8 from the B port, and is finally discharged from the F port, completing the refrigeration cycle.

[0059] When the unit is in heating mode, the first solenoid valve 81 and the second solenoid valve 82 are also kept open, and the electronic expansion valve 83 is closed. After the gaseous refrigerant enters the valve assembly 8 from the F port, it enters the evaporator through the A and B ends, is condensed into liquid refrigerant in the evaporator, and then returns to the dehumidification module from the C and D ends, and is finally discharged from the E port to complete the heating cycle.

[0060] When the unit is in dehumidification mode, the first solenoid valve 81 and the second solenoid valve 82 are closed, and the electronic expansion valve 83 is opened. After the liquid refrigerant enters the valve assembly 8 from the E port, it enters the lower evaporator 12 from the C end through the internal pipeline, absorbs heat through the evaporator, returns to the valve assembly 8 from the A port and throttles in the internal pipeline, then enters the upper evaporator 71 from the D end for heat exchange, and then returns to the dehumidification module from the B port, and finally is discharged from the F port to complete the dehumidification cycle.

[0061] The above process is coordinated with the aforementioned valve components and piping layout. By controlling the opening and closing of the solenoid valve and the electronic expansion valve, flexible switching of the refrigerant flow direction and flow rate can be achieved to meet various working requirements such as cooling, heating and dehumidification.

[0062] The above embodiment is only a specific embodiment of the valve inside the valve assembly of the present invention, and the valve assembly can also increase or decrease valves and pipelines according to the actual needs of the unit.

[0063] Combined with Figure 5 , 9 The length dimension L of the box body 10 is between 1 / 5 and 2 / 5 of the overall length dimension of the indoor unit 2. Such a proportional design can provide sufficient space and stable support for the valve assembly 8 inside, and will not excessively occupy the space outside the indoor unit 2 or affect the connection of the external unit pipeline. The specific preferred size range is 140<L<280. The height dimension H of the box body 10 is larger than the height dimension of the side cover of the indoor unit 2, but smaller than the overall height of the side of the indoor unit 2. The specific preferred size range is 136<H<192. Through this height difference, the box body 10 can fully accommodate a number of solenoid valves, electronic expansion valves 83 and pipeline directions in the vertical direction, and will not be too much higher than the side wall of the indoor unit 2, thereby ensuring sufficient margin for inspection or maintenance while also taking into account the integration and compactness of the appearance of the air-conditioning body.

[0064] The water pump drain pipe 5 passes through or extends from the side of the inner unit 2 housing. In order to avoid blocking or squeezing the drain pipe when installing the air conditioning pipeline module, the structural design of the second splicing box 102 reserves corresponding avoidance space: its housing is partially recessed on the side close to the water pump drain pipe 5, so that the drain pipe can pass smoothly through this area and maintain a certain gap, thereby ensuring that the normal drainage function of the water pump drain pipe 5 will not be disturbed. Fig. 9It can be seen that the second splicing box 102 forms a step by avoiding the bending of the water pump drain pipe 5, so that the upper width of the box body 10 is small and the lower width is large. Specifically, the upper width dimension W1 of the box body 10 is greater than or equal to 1 / 2 of the distance from the edge of the electrical box cover 3 to the edge of the water pump drain pipe 5, that is, half of the distance from the edge P to the edge O, and the width dimension of the box body 10 should be less than or equal to the distance from the edge of the electrical box cover 3 to the edge of the water pump drain pipe 5, that is, the distance from the edge P to the edge O, and the width dimension of the box body 10 is preferably 50<W1<100; the lower width dimension W2 of the box body 10 is greater than or equal to 1 / 2 of the distance from the edge of the electrical box cover 3 to the edge of the water pump drain pipe 5, that is, half of the distance from the edge P to the edge O, and the width dimension of the box body 10 should be less than or equal to the distance from the edge of the electrical box cover 3 to the edge of the foam water tray drain pipe 4, that is, the distance from the edge P to the edge U, and the width dimension is preferably 50<W2<110.

[0065] It should be noted that the unit of the numerical value in the above range is mm.

[0066] The present invention also provides an air conditioning unit, comprising the above-mentioned air conditioning pipeline module.

[0067] The indoor unit of the air-conditioning unit may specifically be a duct unit.

[0068] By simplifying the pipes and valves inside the inner machine, and separately setting the valve pipeline structure used to switch the operating mode outside the inner machine, and modularizing it for easy disassembly and replacement, it is also possible to disassemble and repair it without using a welding gun during after-sales maintenance, which is convenient for troubleshooting and repair.
