Description

Technical Field

[0001] This application relates to the field of heat pump technology, and in particular to a floor-embedded heat pump water tank installation structure. Background Technology

[0002] Heat pump water circulation systems are typically equipped with a buffer tank. This tank significantly increases the water volume in the circulation system, allowing the heat pump to continuously store heated water at a constant temperature. The system operates using a temperature sensor installed inside the tank. When the water temperature in the enamel-lined tank reaches the set temperature, the system stops working. At this point, the underfloor heating system draws heat from the stored high-temperature water. The system resumes heating only when the water level drops to the set value, greatly reducing the workload and operating frequency of the heat pump unit and meeting the user's heating needs at different times. Therefore, the buffer tank in a heat pump serves a buffering and energy storage function. Furthermore, the buffer tank also assists in system venting, pressure release, wastewater drainage, water replenishment, and efficient defrosting. However, existing heat pump buffer tanks are installed on the ground, and their large size (even larger than the heat pump unit) results in excessive space requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a floor-embedded heat pump water tank installation structure that can solve the problem of excessive floor space occupied by existing heat pump buffer water tanks.

[0004] To achieve the above objectives, this application adopts the following technical solution: A floor-mounted embedded heat pump water tank installation structure includes: The raised floor includes a lower floor, supporting columns, and an upper floor. The supporting columns are distributed in a matrix between the lower floor and the upper floor, forming a raised space between the lower floor and the upper floor. A heat pump water tank, installed in the elevated space, includes an upper wall panel, a lower wall panel, and a side wall connecting the upper wall panel and the lower wall panel. A plurality of reinforcing ribs corresponding to the support columns are connected between the upper wall panel and the lower wall panel. The reinforcing ribs are provided with clearance holes corresponding to the support columns, and the support columns pass through the clearance holes.

[0005] Optionally, the heat pump water tank is a blow-molded part.

[0006] Optionally, the heat pump water tank is provided with an inlet connector and an outlet connector on its side wall. The inlet connector and the outlet connector are respectively located on two opposite sides of the heat pump water tank, with the inlet connector below the centerline of the heat pump water tank and the outlet connector above the centerline of the heat pump water tank.

[0007] Optionally, several heat pump water tanks are arranged in the elevated space, and the inlet and outlet connectors of two adjacent heat pump water tanks are connected in series through an intermediate conduit.

[0008] Optionally, in any two adjacent heat pump water tanks, the water outlet of the former heat pump water tank and the water inlet of the latter heat pump water tank are located on the same side or adjacent sides.

[0009] Optionally, it also includes a paving mat, on which the support column is fixed, thereby achieving a matrix layout of the support column based on the paving mat.

[0010] Optionally, each of the paving mats is fixed with a plurality of the support columns.

[0011] Optionally, the paving mat is provided with a dividing groove, through which the paving mat can be divided into several sections.

[0012] Optionally, the side of the paving mat is provided with a protruding buckle and a buckle groove that cooperates with the protruding buckle. By fastening the protruding buckle and buckle groove on the contact side of any two adjacent paving mats, a tight splicing between adjacent paving mats can be achieved.

[0013] Optionally, the paving pad and the support column are integrally injection molded structures.

[0014] The beneficial effects of this application are as follows: This invention provides a floor-embedded heat pump water tank installation structure. By utilizing the raised space in the raised floor, the heat pump water tank is flattened and embedded in the raised floor, which completely eliminates the need to occupy ground space and solves the problem of large ground space occupation in traditional water tank installation.

[0015] To address the issue of support columns in raised floors obstructing the installation of heat pump water tanks, this solution incorporates reinforcing ribs with clearance holes between the upper and lower wall panels of the heat pump water tank. The clearance holes correspond to the positions of the support columns, allowing the entire heat pump water tank to be installed into the raised space without obstructing the support columns during installation. Furthermore, the presence of several reinforcing ribs within the heat pump water tank strengthens the connection between the upper and lower wall panels, significantly improving the strength of the heat pump water tank and ensuring its durability.

[0019] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] To improve the heating experience, raised floors have been developed that can be used to install heating coils or air ducts. (See details below.) Figure 1 The structure shown has a support column 12 laid on the lower floor 11, and an upper floor 13 laid on top of the support column 12. The support column 12 supports the upper floor 13, so that a flat, open space 14 is formed between the upper floor 13 and the lower floor 11.

[0023] Given the technical problem that existing heat pump water tanks 2 are installed on the ground and require too much ground space, this embodiment provides a floor-embedded heat pump water tank installation structure, including a raised floor 1 and a heat pump water tank 2 embedded in the raised floor 1. In application, the heat pump water tank 2 is connected to the heat pump host through an inlet pipe and an outlet pipe, respectively.

[0024] The raised floor 1 includes a lower floor 11, support columns 12 and an upper floor 13. The support columns 12 are distributed in a matrix between the lower floor 11 and the upper floor 13, forming a raised space 14 between the lower floor 11 and the upper floor 13.

[0025] Combination Figure 2-4 The heat pump water tank 2 is installed in the overhead space 14 and includes an upper wall panel 21, a lower wall panel 22 and a side wall 23 connecting the upper wall panel 21 and the lower wall panel 22. A plurality of reinforcing ribs 24 corresponding to the support column 12 are connected between the upper wall panel 21 and the lower wall panel 22. The reinforcing ribs 24 are provided with clearance holes 25 corresponding to the support column 12, and the support column 12 passes through the clearance holes 25.

[0026] In order to embed the heat pump water tank 2 within the overhead space 14, the heat pump water tank 2 in this embodiment is designed to be flat. It can be understood that, in order to provide sufficient water storage space, the heat pump water tank 2 in this embodiment has a larger area on the horizontal plane compared to traditional water tanks. That is, the area of ​​the upper wall panel 21 and the lower wall panel 22 is greatly increased, while the height of the side wall 23 is greatly reduced, thereby forming a flat water tank structure.

[0027] Because numerous support columns 12 are required in the raised floor 1 to support the upper floor 13, the presence of these support columns 12 will inevitably hinder the installation of the heat pump water tank 2. Furthermore, due to the large area of ​​the upper wall panel 21 and lower wall panel 22, the middle section of the upper wall panel 21 and lower wall panel 22 lacks strong support, making it prone to bulging and deformation under the pressure of internal high-pressure water. To address both of these issues, this solution incorporates a middle support column between the upper wall panel 21 and lower wall panel 22. The reinforcing rib 24 structure with the center relief hole 25 connects the upper wall panel 21 and the lower wall panel 22, providing support and restraint for both, preventing the upper wall panel 21 and the lower wall panel 22 from bulging and deforming; at the same time, since the position of the reinforcing rib 24 corresponds one-to-one with the support column 12, the relief hole 25 in the center of the reinforcing rib 24 can directly avoid the support column 12, thereby completely placing the entire heat pump water tank 2 among the numerous support columns 12, realizing the embedded installation of the heat pump water tank 2.

[0028] In the raised floor 1 structure, preferably, an insulation layer is provided on the top layer of the lower floor 11 to insulate the heat pump water tank 2 and reduce heat loss from the heat pump water tank 2; a silicate cover plate layer is provided on the bottom layer of the upper floor 13, and then floor tiles are laid on the silicate cover plate layer. As a new type of green and environmentally friendly building material, silicate cover plate has the functions of traditional gypsum board, but also has the advantages of superior fire resistance, moisture resistance, and ultra-long service life. The silicate cover plate layer at the bottom layer of the upper floor 13 can provide reliable support for the floor tiles on top and ensure their service life.

[0029] In practical applications, to avoid the installation of the heat pump water tank 2 affecting the layout of the heating coil or air duct, the heat pump water tank 2 is preferably installed against the wall, and more preferably in the kitchen or near the bathroom.

[0030] In summary, based on the floor-embedded heat pump water tank installation structure of this embodiment, the heat pump water tank 2 is flattened and embedded in the raised floor 1 by utilizing the raised space 14 in the raised floor 1, which completely eliminates the need to occupy ground space and solves the problem of large ground space occupation in traditional water tank installation.

[0031] Meanwhile, in order to solve the problem that the support column 12 in the raised floor 1 hinders the installation of the heat pump water tank 2, this solution sets a reinforcing rib 24 with a clearance hole 25 between the upper wall panel 21 and the lower wall panel 22 of the heat pump water tank 2. The position of the clearance hole 25 corresponds to the position of the support column 12. During installation, the support column 12 can be completely bypassed through the clearance hole 25 to install the entire heat pump water tank 2 into the raised space 14. At the same time, the arrangement of several reinforcing ribs 24 in the heat pump water tank 2 can strengthen the connection between the upper wall panel 21 and the lower wall panel 22, thereby significantly improving the strength of the heat pump water tank 2 and ensuring its durability.

[0032] Preferably, the support column 12 is in the shape of a cylindrical trapezoid. After the heat pump water tank 2 is fitted in, under its own gravity, the downward-pressed clearance hole 25 will gradually fit tightly against the outer wall of the support column 12, improving the reliability of the installation of the heat pump water tank 2. In other embodiments, the support column 12 can also be a cylindrical, prismatic, or columnar structure with positioning points, and those skilled in the art can freely choose to apply it.

[0033] Regarding the molding structure of the heat pump water tank 2, as a preferred embodiment, the heat pump water tank 2 is a blow-molded part.

[0034] Specifically, a heat pump water tank 2 with a water storage cavity and reinforcing ribs 24 can be quickly formed in a mold by blow molding. This method has the advantages of fast molding and low production cost.

[0035] It is important to note that due to the high pressure in heat pump water circulation systems, traditional water tanks are typically made of steel to prevent deformation or damage under prolonged high pressure. Some tanks also require enamel lining to ensure sufficient pressure resistance. Traditionally, using plastic to manufacture heat pump water tanks is not feasible because plastic generally has limited pressure resistance, and tanks made from it lack sufficient pressure resistance to meet the requirements of heat pump water circulation systems.

[0036] However, by flattening the heat pump water tank 2 in this design, the internal surface area of ​​the heat pump water tank 2 is significantly increased under the same water volume. Therefore, under the same water pressure, the pressure on the wall panels of the heat pump water tank 2 in this design is much lower than that of the wall panels of traditional square or cylindrical water tanks. Moreover, this design incorporates numerous reinforcing ribs 24 between the upper wall panel 21 and the lower wall panel 22. The connection of these reinforcing ribs 24 significantly improves the pressure-bearing capacity of the upper wall panel 21 and the lower wall panel 22, preventing deformation or damage. Therefore, based on the structure of this design, the heat pump water tank 2 manufactured using blow molding can meet the usage requirements of the heat pump circulating water circuit.

[0037] To enable water supply and drainage of the heat pump water tank 2, an inlet connector 26 and an outlet connector 27 are provided on the side wall 23 of the heat pump water tank 2. The inlet connector 26 and the outlet connector 27 are respectively located on two opposite sides of the heat pump water tank 2, with the inlet connector 26 below the centerline of the heat pump water tank 2 and the outlet connector 27 above the centerline of the heat pump water tank 2.

[0038] The inlet connector 26 and outlet connector 27 are located on the side wall 23, allowing for side connection of the heat pump water tank 2. This facilitates connection operations without occupying vertical space in the heat pump water tank 2, thus enabling the design to maximize the height of the heat pump water tank 2. The vertically positioned outlet connector 27 and inlet connector 26 ensure sufficient water storage within the heat pump water tank 2, reducing the generation of air bubbles inside the heat pump water tank 2.

[0039] By placing the inlet connector 26 and outlet connector 27 of the heat pump water tank 2 on two opposite sides of the heat pump water tank 2, the water in the entire heat pump water tank 2 can participate in the circulation during operation, realizing the functions of energy storage, buffering, venting, and depressurization of the heat pump water tank 2.

[0040] In some embodiments, a plurality of the heat pump water tanks 2 are arranged in the overhead space 14, and the inlet connectors 26 and outlet connectors 27 of two adjacent heat pump water tanks 2 are connected in series through an intermediate conduit 3.

[0041] Specifically, the heat pump water tank 2 in this method is modularly designed. When applying it, the appropriate number of heat pump water tanks 2 can be freely selected and combined according to the usage volume requirements of the heat pump water tank 2, which also facilitates the flexible arrangement of the heat pump water tank 2.

[0042] Therefore, the heat pump water tank 2 in this solution can be mass-produced in a standardized manner during the factory production stage, and can meet various different capacity requirements and different spatial layouts during application. It has the advantages of being easy to produce and easy to install.

[0043] Preferably, in any two adjacent heat pump water tanks 2, the water outlet connector 27 of the preceding heat pump water tank 2 and the water inlet connector 26 of the following heat pump water tank 2 are located on the same side or adjacent sides.

[0044] Specifically, in application, two adjacent heat pump water tanks 2 need to be connected in series through an intermediate conduit 3. Among the two heat pump water tanks 2 located on the outermost sides, the inlet connector 26 of one heat pump water tank 2 needs to be connected to the outlet end of the heat pump host through an inlet pipe, and the outlet connector 27 of the other heat pump water tank 2 needs to be connected to the inlet end of the heat pump host through an outlet pipe.

[0045] During installation, this scheme places the outlet connector 27 and inlet connector 26 of any two adjacent heat pump water tanks 2 on the same side or adjacent sides. The purpose is to allow the outlet connector 27 of the preceding heat pump water tank 2 to be closer to the inlet connector 26 of the following heat pump water tank 2, thereby minimizing the pipe length of the intermediate conduit 3. Specifically, taking the inlet connector 26 and outlet connector 27 respectively located on the left and right sides of the heat pump water tank 2 as an example, when the two heat pump water tanks 2 are arranged horizontally side by side (i.e., Figure 2 When arranged as shown, the outlet connector 27 and inlet connector 26 of the two heat pump water tanks 2 are located on the same side; when the two heat pump water tanks 2 are arranged longitudinally side by side or perpendicular to each other (i.e., Figure 6 In the arrangement shown, the outlet connector 27 and inlet connector 26 of the two heat pump water tanks 2 are located on adjacent sides.

[0046] In the structure of the raised floor 1, to facilitate the installation and fixing of the support columns 12, in one embodiment, refer to Figure 5It also includes a paving mat 15, on which the support column 12 is fixed, thereby realizing the matrix layout of the support column 12 based on the paving mat 15.

[0047] Specifically, according to the matrix design dimensions of the support columns 12, the support columns 12 are fixed on the paving mats 15 according to the design positions. After the paving mats 15 are laid on the lower floor 11 and spliced, the matrix layout of the support columns 12 is completed, that is, the paving mats 15 are used to position and fix the support columns 12. One support column 12 can be set on one paving mat 15, or multiple support columns 12 can be set.

[0048] This solution utilizes paving pads 15 to install the support columns 12 in a modular fashion, similar to building block assembly. This allows for quick and efficient, accurate positioning of the support columns 12. Furthermore, because the support columns 12 and paving pads 15 can be produced modularly, their dimensional accuracy is easily controlled, resulting in high spacing accuracy between the support columns 12 after installation, which helps ensure the airtightness of the ventilation ducts. Moreover, no further fixing measures are required for the support columns 12 after installation, simplifying the installation process.

[0049] Preferably, each of the paving pads 15 is fixed with a plurality of the support columns 12.

[0050] By setting several support columns 12 on a paving mat 15, multiple support columns 12 can be installed by assembling a paving mat 15, which can effectively improve paving efficiency.

[0051] Optionally, the paving mat 15 is provided with a dividing groove 153, through which the paving mat 15 can be divided into several sections.

[0052] A dividing groove 153 is provided on the paving mat 15. When obstacles such as walls or columns are encountered during the paving process, the excess structure of the paving mat 15 can be quickly and accurately cut off based on the dividing groove 153 to adapt to the paving environment.

[0053] In one embodiment, the side of the paving mat 15 is provided with a protruding buckle 151 and a buckle groove 152 that cooperates with the protruding buckle 151. By fastening the protruding buckle 151 and buckle groove 152 on the contact side of any two adjacent paving mats 15, a tight splicing between adjacent paving mats 15 is achieved.

[0054] During assembly, the interlocking of the protruding buckle 151 and the interlocking groove 152 can achieve a tight connection between each paving pad 15, while avoiding the overlap between the paving pads 15. At the same time, it can improve the standardization and firmness of the paving and increase the installation efficiency.

[0055] Preferably, the paving pad 15 and the support column 12 are integrally injection molded structures.

[0056] The one-piece molded structure ensures reliable connection between the paving pad 15 and the support column 12, high dimensional accuracy, and easy standardization for large-scale production in factories, which helps improve production efficiency and reduce production costs.
