Description

Technical Field

[0001] The utility model relates to the technical field of house air supply, in particular to a floor air supply duct, a floor heating laying structure, an air supply system and an indoor temperature regulating system. Background Art

[0002] In order to be able to deliver the treated air to the required rooms or areas, existing air handling systems, air conditioning systems, etc. generally use air ducts installed in the ceiling to supply air. Especially for flat-floor apartments, when the air duct needs to be installed in the room, it is likely that holes will need to be punched in the beams to allow the air duct to pass through. However, there are certain hidden dangers in punching holes in the beams, which will damage the structure of the beams and reduce the strength of the beams. If the air ducts are arranged through beam wraps, the floor height will be reduced, and the local resistance of the air ducts will be greatly increased. In addition, since the floor height of the flat itself is limited, the use of top air supply will increase the height occupied by the ceiling, which will further reduce the height from the ceiling to the ground, greatly affecting the user experience.

[0003] Therefore, some floor air ducts have appeared on the market. These ducts are laid on the ground to deliver treated air to the rooms or areas where it is needed. However, if the room or area also needs to lay other pipes on the ground, such as water pipes for floor heating, the area where the floor air duct is laid will be inconvenient or impossible to lay other pipes, thus causing certain difficulties in laying other pipes.

[0075] The details of the present invention can be more clearly understood by referring to the accompanying drawings and the description of the specific embodiments of the present invention. However, the specific embodiments of the present invention described herein are for the purpose of explaining the present invention only and should not be construed as limiting the present invention in any way. Based on the teachings of the present invention, skilled artisans can conceive of any possible variations based on the present invention, which should be considered to fall within the scope of the present invention.

[0076] In order to solve the problem of inconvenience in laying pipes when supplying air to a room through a floor air duct, a floor air duct is proposed in this application. Figure 1This is a schematic structural diagram of the air supply duct in the first embodiment of the present utility model. Figure 2 FIG. 1 is a schematic structural diagram of the air supply duct in the second embodiment of the present utility model. Figure 1 and Figure 2 As shown, the floor air supply duct 100 may include: a tube body 1, an air supply duct 13 is formed inside the tube body 1, a first port 11 and a second port 12 are provided on the tube body 1, the first port 11 is connected to the second port 12 through the air supply duct 13; a limiting portion 14 for installing the pipeline 300 is provided on the upper end surface 16 of the tube body 1.

[0077] The floor air supply duct 100 in the present application can supply air through the air supply duct 13 formed inside the tube body 1. Multiple floor air supply ducts 100 can be connected to form a complete air supply duct 1100. The floor air supply duct 100 is used to be laid above the base layer 800 of the ground. Since the upper end surface 16 of the tube body 1 has a limit portion 14 for installing the pipeline 300, when the floor air supply duct 100 is laid above the base layer 800 of the ground, the pipeline 300 can be installed at the limit portion 14 of the upper end surface 16 of the tube body 1 for limitation, so that the pipeline 300 can still be laid over the floor air supply duct 100 without affecting the laying of the pipeline 300.

[0078] As feasible, Figure 7 This is a structural diagram of the floor air supply duct and the floor heating mushroom plate laid side by side and installed with a heating water pipe in the embodiment of the present utility model, as shown in FIG. Figure 7 As shown, the pipeline 300 can be a heating water pipe 3001. In a room or area where heating is installed, the heating water pipe 3001 is laid on the floor heating mushroom plate 200, and the heating water pipe 3001 is fixed by the floor heating mushroom plate 200. The floor air supply duct 100 can be laid side by side with the floor heating mushroom plate 200. In the area where the floor air supply duct 100 passes, the floor heating mushroom plate 200 is not laid, and the floor air supply duct 100 is replaced. The limiting portion 14 of the upper end surface 16 of the floor air supply duct 100 can be similar to the mushroom head structure of the floor heating mushroom plate 200, and the arrangement of the limiting portion 14 can also be similar to the arrangement position of the mushroom head. This arrangement makes the pipeline installation similar to the operation of installing it on the floor heating mushroom plate 200. By utilizing the limiting portion 14 of the upper end surface 16 of the floor air supply duct 100 , the heating water pipe 3001 can be laid normally on the floor heating mushroom plate 200 and the upper end surface 16 of the floor air supply duct 100 according to its own planned route without being affected in any way.

[0079] As a feasible method, the air supply duct 13 can extend along a straight line, with the first port 11 and the second port 12 being arranged opposite to each other. A plurality of such air supply ducts 13 can be connected to form a straight air supply pipe 1100 .

[0080] As is feasible, in another embodiment, Figure 4 FIG. 1 is a structural diagram of the fourth embodiment of the present invention in which the ground air supply duct is installed in conjunction with the ground air supply duct in the first embodiment. Figure 4 As shown, the air supply duct 13 can extend along an arc, with a preset angle between the orientation of the first port 11 and the orientation of the second port 12. This type of air supply duct 13 can be used for laying around corners, and can be combined with an air supply duct 13 extending along a straight line to meet the requirements of turning the air supply duct 1100. The preset angle can be any angle between 0 and 180 degrees. To make the curved ground air supply duct 100 more practical, the preset angle can be 90 degrees, 45 degrees, 30 degrees, or 60 degrees, etc.

[0081] Alternatively, the air supply duct 13 may have a first port 11 as an inlet and multiple second ports 12 as outlets. This type of ground air supply duct 100 can function as a diversion device. A single main air supply duct 13 can be divided into multiple branch air supply ducts 13. Both the main air supply duct 13 and the branch air supply ducts 13 can utilize ground air supply ducts 100.

[0082] For example, the air supply cross-section of the floor air supply duct 100 may have different sizes and types, so that the floor air supply duct 100 includes a floor air supply duct 100 main pipe and a floor air supply duct 100 branch pipe, thereby meeting different laying requirements.

[0083] As a feasible method, in another type of structure of the air supply duct 100, Figure 3 FIG. 1 is a schematic structural diagram of the air supply duct in the third embodiment of the present utility model. Figure 3 As shown, there is one first port 11 and two second ports 12. One first port 11 is positioned opposite one second port 12, and the other second port 12 is located on the side of the tube body 1. This ground air supply duct 100 allows one air supply duct 13 to make a 90-degree turn while the other air supply duct 13 continues to extend in a straight line. Alternatively, the second port 12 at the end of the straight air supply duct 13 can be blocked, for example, with a sealing member, to meet specific needs.

[0084] In one possible implementation, Figure 1 As shown, the limiting portion 14 may include a raised portion. There are at least two limiting portions 14. The space between two adjacent limiting portions 14 accommodates the pipeline 300, and the two adjacent limiting portions 14 are used to limit the position of the pipeline 300. The specific structure of the limiting portion 14 can effectively limit the position of the pipeline 300, meeting the laying requirements of the pipeline 300.

[0085] When the air supply duct 13 of the local air supply duct 100 extends along a straight line, there can be multiple limiting parts 14. The multiple limiting parts 14 are distributed in several rows, and the limiting parts 14 on each row are arranged along the extension direction of the air supply duct 13; the arrangement direction of the multiple rows of limiting parts 14 is perpendicular to the extension direction of the air supply duct 13. In one feasible way, the limiting parts 14 in adjacent rows are used to accommodate the pipeline 300, and the pipeline 300 extends along the extension direction of the air supply duct 13. In another feasible way, the pipeline 300 extends in a direction perpendicular to the extension direction of the air supply duct 13. In this way, the limiting parts 14 in adjacent rows can be staggered or completely one-to-one. Similarly, the extension distribution of the limiting parts 14 on the upper end face 16 of the floor air supply duct 100 can be similar to the arrangement position of the mushroom head. This arrangement makes the pipeline installation similar to the operation of installing it on the floor heating mushroom plate 200.

[0086] Since the floor height of a typical single-story house is limited, the overall height of the floor air duct 100 cannot be too high, otherwise the floor height of the house will be further reduced. At the same time, considering the diameter of the generally laid pipe 300, the height of the raised portion can preferably be less than or equal to 16 mm. At this size, not only can the floor air duct 100 be used in conjunction with the existing floor heating mushroom plate 200 on the market, but the height of the air supply cross section within the floor air duct 100 can also be maximized, thereby reducing the resistance to gas flow. In addition, the overall height of the entire floor air duct 100 will not be too high, ensuring a relatively large height between the ceiling and the floor decorative surface layer in the house to avoid users feeling oppressive in the space.

[0087] In another possible embodiment, Figure 2 As shown, the limiting portion 14 may include a recessed portion for accommodating and limiting the position of the pipeline 300. The specific structure of the limiting portion 14 can also limit the position of the pipeline 300 and meet the laying requirements of the pipeline 300.

[0088] Furthermore, when the air supply duct 13 of the local air supply duct 100 extends along a straight line, the extension direction of the recessed portion can be parallel to or perpendicular to the extension direction of the air supply duct 13. With this structure, the pipeline 300 can be laid along the extension direction of the air supply duct 13 or perpendicular to the extension direction of the air supply duct 13.

[0089] As a feasible option, the height of the recessed portion may preferably be less than or equal to 16 mm.

[0090] The tube body 1 has an upper end face 16 and a lower end face 17, and a left side face 18 and a right side face 19. In order to improve the vertical support capacity of the floor air supply duct 100, it is feasible to Figures 1 to 3As shown, the tube body 1 further includes a support portion 15 located in the air supply duct 13 and connecting the upper end surface 16 and the lower end surface 17. The support portion 15 is generally located in the middle area of ​​the tube body 1 in the horizontal direction. The support portion 15 can have various forms. For example, there can be multiple support portions 15, and the support portion 15 is columnar. For another example, the support portion 15 can extend along the extension direction of the air supply duct 13 and can be generally sheet-shaped. Of course, there can also be multiple support portions 15, and the multiple support portions 15 are arranged in an arrangement perpendicular to the extension direction of the air supply duct 13.

[0091] In order to meet the air supply volume of the rooms in ordinary flat houses, the cross-sectional area of ​​the air supply duct 13 needs to be greater than or equal to 0.006m 2 In order to reduce the air supply resistance of the ground air supply duct 100, the width of the air supply duct 13 in the horizontal direction cannot be too large, and the height in the vertical direction cannot be too small. Therefore, the aspect ratio of the air supply cross section of the air supply duct 13 needs to be controlled between 3.0-4.8.

[0092] In all the above embodiments, as feasible, Figure 5 FIG. 1 is a schematic structural diagram of the intermediate connecting member in the first embodiment of the present utility model. Figure 5 As shown, the first port 11 may have a first plug-in portion, and the second port 12 may have a second plug-in portion, and the first plug-in portion is identical to the second plug-in portion. The first plug-in portion can be connected to the second plug-in portion through an intermediate connector 400. The two ends of the intermediate connector 400 respectively have the same third plug-in portion 4001, and the third plug-in portion 4001 can be connected to the first plug-in portion and the second plug-in portion. This connection method can generally be selected as plug-in, which facilitates the direct and quick installation and connection of the floor air supply duct 100. For example, the first plug-in portion and the second plug-in portion are stepped, and the third plug-in portion 4001 is stepped to match the first plug-in portion, and plug-in can be achieved through this structure. In order to improve the sealing between the two connected floor air supply ducts 100, an annular seal can be provided between the first plug-in portion or the second plug-in portion and the third plug-in portion 4001 of the intermediate connector 400. An annular seal can be used to achieve a radial seal between the first or second plug-in portion and the third plug-in portion 4001 of the intermediate connector 400, preventing the intermediate connector 400 from loosening from the floor air duct 100. In this manner, any port of a floor air duct 100 can be connected to any port of another floor air duct 100 via the intermediate connector 400. The intermediate connector 400 is of the internal direct connection type, while the first and second plug-in portions are of the external direct connection type.

[0093] In another embodiment, Figure 6 FIG. 1 is a schematic structural diagram of the intermediate connecting member in the second embodiment of the present utility model. Figure 6As shown, the intermediate connector 400 is of the external direct type. The first port 11 may have a first plug-in portion, and the second port 12 may have a second plug-in portion. The first plug-in portion and the second plug-in portion are identical, which is an internal direct type. The first plug-in portion and the second plug-in portion directly plug into the intermediate connector 400. Of course, in other feasible embodiments, the first plug-in portion of the first port 11 can directly mate with the second plug-in portion of the second port 12, such as a plug-in connection.

[0094] This application also proposes a floor heating laying structure. Figure 7 This is a structural diagram of the embodiment of the present invention in which the floor air supply duct and the floor heating mushroom plate are laid side by side and a heating water pipe is installed. Figure 8 This is another structural diagram of the embodiment of the present invention in which the floor air supply duct and the floor heating mushroom plate are laid side by side and a heating water pipe is installed. Figure 7 and Figure 8 As shown, the floor heating laying structure may include: a floor heating mushroom plate 200; a floor air supply duct 100 such as any of the above-mentioned ones laid side by side with the floor heating mushroom plate 200; and a heating water pipe 3001 installed at the limiting portion 14 and / or the pipe 300 installation portion of the floor heating mushroom plate 200.

[0095] In the above embodiment, the overall thickness of the floor air supply duct 100 can be similar to / equal to the overall thickness of the floor heating mushroom plate 200, so that the heating water pipe 3001 can be laid at the same height.

[0096] In this floor heating laying structure, Figure 9 This is a schematic diagram of the floor heating installation structure in accordance with an embodiment of the present invention. Figure 9 As shown, the floor heating laying structure may include: a mortar layer 500 located above the floor heating mushroom board 200 and the floor air supply duct 100; a decorative surface layer 600 located above the mortar layer 500; and a functional layer 700 located below the floor heating mushroom board 200 and the floor air supply duct 100. The decorative surface layer 600 is a layer that comes into contact with the user's feet. For example, the decorative surface layer 600 may be formed by laying floorboards, tiles, etc. The functional layer 700 may be a layer 700 that implements some specific functions. These functions may include but are not limited to one of the following: heat preservation, moisture-proofing, etc. In a specific embodiment, the functional layer 700 may include at least one of the following: a reflective film layer, a heat-insulating board layer, a moisture-proof film layer, etc. When the functional layer 700 includes a reflective film layer, a heat-insulating board layer, and a moisture-proof film layer, the reflective film layer is located above the heat-insulating board layer, and the moisture-proof film layer is located below the heat-insulating board layer. The functional layer 700 is located above the ground 800.

[0097] In this application, an air supply system is also proposed. Figure 10 FIG. 1 is a schematic diagram of the structure of the air supply system in an embodiment of the present utility model. Figure 10As shown, the air supply system may include: an air treatment device 900, the air treatment device 900 includes an air supply port; an air distribution box 1000, the inlet of the air distribution box 1000 is connected to the air supply port, and the air distribution box 1000 has multiple outlets; multiple air supply ducts 1100 respectively connected to the multiple outlets of the air distribution box 1000, the air supply duct 1100 includes multiple ground air supply ducts 100 connected in sequence as any of the above-mentioned ones; an air outlet piece 1200 connected to the end of the air supply duct 1100.

[0098] The air distributor 1000 is used to divide the input air into multiple paths, which are then output from the outlets. The air in the air supply duct 1100 eventually flows out through the air outlet 1200 and enters the room or area. The air outlet 1200 can be installed on the ground 800 or on the wall. Generally speaking, the outlet of the air outlet 1200 has a hollow structure, which ensures the output of gas on the one hand and prevents foreign matter from entering the air outlet 1200 and the ground air supply duct 100 on the other hand.

[0099] As is feasible, the inlet of the air distribution box 1000 is connected to the air supply port through a connecting pipe 1300 with a generally circular or rectangular cross-section. For example, when the air supply port of the air treatment device 900 is set upward or horizontally, the inlet of the air distribution box 1000 is connected to the air supply port through a connecting pipe 1300 with a curvature. The shape of the inlet of the air distribution box 1000 can correspond to the cross-section of the connecting pipe 1300. If they do not correspond, they can be connected through an adapter. If the air supply port of the air treatment device 900 is set downward, the inlet of the air distribution box 1000 can be connected to the air supply port through a straight connecting pipe 1300. The air distribution box 1000 can be installed in a relatively concealed position so as not to affect the aesthetics of the room. Generally speaking, the inlet of the air distribution box 1000 is located at the upper end face 16 and faces upward, and the outlet of the air distribution box 1000 is located at the side wall and faces horizontally. In this way, the air distribution box 1000 is generally set at a height position on the ground 800 that is almost the same as the laid ground air supply duct 100, so that the air supply duct 1100 with the ground air supply duct 100 can be connected to the outlet of the air distribution box 1000.

[0100] In other possible implementations, Figure 11 This is a structural diagram of the connection between the connecting pipe and the floor air supply duct in the embodiment of the utility model. Figure 12 This is another structural diagram of the connection between the connecting pipe and the ground air supply duct in the embodiment of the present utility model, as shown Figure 11 and Figure 12As shown, the air supply port of the air treatment device 900 can be connected to the air supply duct 1100 without connecting the air distribution box 1000 in the middle. The air supply port of the air treatment device 900 can be connected to the air supply duct 1100 through the connecting pipe 1300. After that, the ground air supply duct 100 in the air supply duct 1100 realizes the diversion of air through the ground air supply duct 100 having multiple second ports 12 as outlets.

[0101] As feasible, Figure 11 and Figure 12 As shown, the floor air duct 100 and the air outlet 1200 can be connected via a connecting pipe 1300. In this embodiment, the connecting pipe 1300 can be substantially perpendicular to the floor air duct 100, and the two can be connected using an elbow. For example, if the air outlet 1200 is installed on a wall, the air output from the floor air duct 100 needs to be transported to the air outlet 1200 on the wall through the connecting pipe 1300 and the elbow.

[0102] The air output from the air supply port of the air treatment device 900, such as the treated air, is divided into multiple paths by the air distribution box 1000, and then flows into the air supply duct 1100 respectively, and is transported to the corresponding room or area through the air supply duct 1100, and then outputted into the room or area through the air outlet piece 1200. Since an air supply duct 1100 may extend in a straight line or may have a turn in the middle. Therefore, the multiple ground air supply ducts 100 in at least one of the air supply ducts 1100 may include a ground air supply duct 100 whose air supply duct 13 extends along a straight line and a ground air supply duct 100 whose air supply duct 13 extends along an arc. When an air supply duct 1100 extends in a straight line, the multiple ground air supply ducts 100 in the air supply duct 1100 may include a ground air supply duct 100 whose air supply duct 13 extends along a straight line.

[0103] As a feasible method, the air supply system may be a fresh air system, and in this case, the air treatment device 900 is a fresh air device.

[0104] As a feasible method, the air supply system may be an all-air system. In this case, the air treatment device 900 is used to perform temperature and / or humidity control on the output air.

[0105] This application also proposes an indoor temperature control system, which includes: an air supply system such as any of the above-mentioned ones; a heating system, the heating system including a heating water output device; a heating water pipe 3001 for laying on the ground air supply pipe, the heating water pipe 3001 being connected to the heating water output device.

[0106] In other possible implementations, Figure 13FIG. 1 is a schematic structural diagram of an air treatment device having a first heat exchange unit and a second heat exchange unit connected to a heating water pipe in an embodiment of the present invention. Figure 13 As shown, the air treatment device 900 can output processed air and heat exchange medium. The heat exchange medium is a liquid and can be output to a terminal device, such as a heating device 1400 or a fan coil unit 1500 having a heating water pipe 3001. The air treatment device 900 may include a first heat exchange unit and a second heat exchange unit. The first heat exchange unit is used to adjust the temperature and / or humidity of the air output from the air supply port; the second heat exchange unit is used to adjust the temperature of the output heat exchange medium. The first heat exchange unit and the second heat exchange unit can be arranged in a housing 9001. The air treatment device may also include an external unit 9002. The external unit 9002 is used to supply processed refrigerant to the first heat exchange unit and the second heat exchange unit. The refrigerant flows through the first heat exchange unit and / or the second heat exchange unit to exchange heat with the air and / or the heat exchange medium and then flows back to the external unit 9002. Of course, the air treatment device may also include related components such as a driving pump for driving the flow of heat exchange medium and a compressor for compressing the refrigerant. The driving pump may be arranged in the housing 9001, and the compressor may be arranged in the housing 9001 or in the external unit 9002. The external unit 9002 has a third heat exchange unit for exchanging heat with the outside air.

[0107] In this application, an indoor temperature control system is also proposed. Figure 13 As shown, the indoor temperature control system may include: an air supply system, wherein the air handling unit 900 in the air supply system is capable of outputting treated air and heat exchange medium; a heating water pipe 3001, which is laid on the floor air supply duct 100 and is used to receive the heat exchange medium after temperature regulation by the second heat exchange unit of the air handling unit 900. The heat exchange medium output by the air handling unit 900 can be delivered to terminal equipment such as the heating device 1400 and the fan coil unit 1500. After passing through the terminal equipment, the heat exchange medium can flow back to the second heat exchange unit of the air handling unit. The treated air output by the air handling unit 900 can be delivered to the desired room or area through the air supply duct 1100 formed by the floor air supply duct 100.
