Description

Technical Field

[0001] This utility model relates to a slot-embedded phase change energy storage floor, belonging to the field of flooring technology. Background Technology

[0002] With economic development and improved living standards, people's requirements for indoor temperature and comfort are gradually increasing. Currently, indoor environments are mostly improved through electrical appliances (air conditioners, heating equipment, etc.), all of which consume energy. To improve indoor comfort and for environmental protection and energy conservation, the industry has begun researching the embedding of phase change energy storage materials into building materials. When the ambient temperature approaches its phase change point, the phase change material within the material significantly slows down the rate of temperature change by absorbing heat through melting or releasing heat through solidification, giving the material a "temperature buffering" capability. This endows the material with the ability to actively regulate heat and maintain a suitable temperature inside the building. Therefore, designing a floor with embedded phase change energy storage materials has become a focus of industry research. Utility Model Content

[0003] The purpose of this invention is to provide a slot-embedded phase change energy storage floor. This invention achieves reliable connection and convenient installation between the base plate and the top plate through a special connecting structure design. Simultaneously, by accommodating the energy storage packs within the slots, it utilizes the latent heat characteristics of the phase change energy storage material to regulate indoor temperature.

[0004] The technical solution of this utility model is as follows: A slot-embedded phase change energy storage floor includes a base plate and an upper plate. The base plate has a receiving slot, in which a phase change energy storage pack is placed. The upper surface of the base plate is provided with a plurality of first mounting holes, and a first connector is provided in the first mounting holes. The lower surface of the upper plate is provided with a plurality of second mounting holes corresponding to the first mounting holes, and a second connector is provided in the second mounting holes. The second connector cooperates with the first connector. The first connector includes a first mounting part disposed in the first mounting hole. The upper end of the first mounting part is provided with a first cylinder, and the outer end of the first cylinder is provided with a second cylinder. The diameter of the first cylinder is smaller than the diameter of the second cylinder. The second connector includes a second mounting part disposed in the second mounting hole. A through groove is provided through the middle of the second mounting part. The inner wall of the through groove is provided with a first protruding ring that slopes upward. When the first connector and the second connector cooperate, the first protruding ring abuts against the lower end surface of the second cylinder.

[0005] The first mounting part of the aforementioned slot-embedded phase change energy storage floor is composed of multiple inverted frustums stacked coaxially.

[0006] The aforementioned slot-embedded phase change energy storage floor has multiple second convex rings with triangular cross-sections on the upper side of the second mounting part; and multiple vertical grooves are distributed around the circumference of the second mounting part.

[0007] The aforementioned slot-embedded phase change energy storage floor has an annular groove located on the side of the first convex ring in the second mounting part.

[0008] The aforementioned slotted phase change energy storage floor has handle slots on both sides of the upper plate.

[0009] The aforementioned slot-embedded phase change energy storage floor has multiple linearly distributed first expansion slots on the bottom surface of the receiving slot; and multiple linearly distributed second expansion slots on the lower end surface of the upper plate.

[0010] In the aforementioned slot-embedded phase change energy storage floor, the first connector and the second connector are made of plastic.

[0011] Compared with the prior art, this utility model has the following beneficial effects: In this utility model, the first mounting part of the first connector is inserted into the first mounting hole, and the second mounting part of the second connector is inserted into the second mounting hole. Then, the phase change energy storage pack is placed into the receiving groove of the base plate, and the upper plate is aligned and connected with the base plate. During this process, the second cylinder of the first connector first penetrates the through groove of the second connector. Because the diameter of the second cylinder is larger, it will push the first convex ring against the first ring groove. After the second cylinder is fully inserted into the second connector, the second cylinder does not abut against the first convex ring. The first convex ring resets under its own elastic force, thereby abutting against the lower end face of the second cylinder, realizing a quick and stable connection between the base plate and the upper plate. When the phase change energy storage pack in the receiving groove loses its function due to long-term aging, by holding the handle groove with both hands and applying upward force, a force away from the base plate is applied to the upper plate. This force causes the second cylinder to move downward against the first convex ring, causing the first convex ring to push downward. After the second cylinder is completely pulled out, the first convex ring resets itself. In addition, since the first and second connectors are made of plastic, they have a certain degree of elasticity. When the phase change energy storage pack releases or absorbs energy, causing the upper plate and the bottom plate to expand and contract due to heat, they can still be well fixed in the corresponding mounting holes, ensuring the stability of the connection between the bottom plate and the upper plate.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] Example: A slot-embedded phase change energy storage floor, configured as follows Figure 1-6 As shown, it includes a base plate 1 and an upper plate 2, both of which are made of wood. Figure 2 As shown, the base plate 1 has a receiving groove 3, and a phase change energy storage pack 4 is placed in the receiving groove 3. There is a gap between the phase change energy storage pack 4 and the side wall of the receiving groove 3 to allow for thermal expansion of the phase change energy storage pack 4. The phase change energy storage pack 4 can store and release heat to achieve temperature control. The phase change energy storage pack 4 is usually a block product made of existing phase change materials and is wrapped and sealed with a waterproof sealing film. For example, polyethylene terephthalate (PET) has the characteristics of high transparency, tensile strength, oil and water resistance, and can be used as a wrapping and sealing material for phase change energy storage blocks. (Phase change materials can be commercially available, such as Zero Carbon Future GPCMCOM-18-LID or Glacier Refrigerant LM-XR series, etc.) The phase change energy storage pack 4 releases or absorbs heat through a phase change process (solid-to-liquid conversion) within a specific temperature range. Utilizing the principle of phase change, the phase change point of the energy storage material is set within the controlled temperature range, such as 18-26℃. Through the storage and release of latent heat, it smooths out indoor temperature fluctuations and improves environmental comfort. Figure 3 As shown, the upper surface of the base plate 1 is provided with a plurality of first mounting holes 5, and a first connecting member 6 is provided in the first mounting hole 5; as Figure 4 As shown, the lower end face of the upper plate 2 is provided with a plurality of second mounting holes 7 corresponding to the first mounting holes 5. Second connecting parts 8 are provided within the second mounting holes 7, and the second connecting parts 8 cooperate with the first connecting parts 6. The first connecting parts 6 and the second connecting parts 8 are made of polypropylene plastic, which has wear resistance, impact resistance, and a certain elastic deformation capacity, and can adapt to the thermomechanical stress during long-term use of the floor system. Figure 5As shown, the first connector 6 includes a first mounting portion 9 disposed within the first mounting hole 5, the upper end of the first mounting portion 9 having a first cylinder 10, and the outer end of the first cylinder 10 having a second cylinder 11; the diameter of the first cylinder 10 is smaller than the diameter of the second cylinder 11; the second connector 8 includes a second mounting portion 12 disposed within the second mounting hole 7, as shown... Figure 6 As shown, a through groove 13 is provided through the middle of the second mounting part 12. The inner wall of the through groove 13 is provided with a first protruding ring 14 that slopes upward. When the first connector 6 and the second connector 8 are engaged, the first protruding ring 14 abuts against the lower end face of the second cylinder 11. The second mounting part 12 is provided with an annular groove 17 located on the side of the first protruding ring 14. Insert the first mounting part 9 of the first connector 6 into the first mounting hole 5, insert the second mounting part 12 of the second connector 8 into the second mounting hole 7, and then place the phase change energy storage pack 4 into the receiving groove 3 of the base plate 1. Align and connect the upper plate 2 with the base plate 1. During this process, the second cylinder 11 of the first connector 6 first penetrates the through groove 13 of the second connector 8. Because the diameter of the second cylinder 11 is larger, it will push the first convex ring 14 against the first ring groove 17. After the second cylinder 11 is fully inserted into the second connector 8, the second cylinder 11 does not abut against the first convex ring 14. The first convex ring 14 resets under its own elastic force, thereby abutting against the lower end face of the second cylinder 11, realizing a quick and stable connection between the base plate 1 and the upper plate 2. When the phase change energy storage pack 4 in the receiving tank 3 becomes ineffective due to long-term aging, by holding the handle slot 18 with both hands and applying upward force, a force is applied to the upper plate 2 away from the bottom plate 1. This force causes the second cylinder 11 to move downward against the first convex ring 14, pushing the first convex ring 14 downward. After the second cylinder 11 is completely pulled out, the first convex ring 14 automatically resets. In addition, because the first connecting piece 6 and the second connecting piece 8 are made of plastic, they have a certain degree of elasticity. When the phase change energy storage pack 4 releases or absorbs energy, causing the upper plate 2 and the bottom plate 1 to expand and contract due to heat, they can still be well fixed in the corresponding mounting holes, ensuring the stability of the connection between the bottom plate 1 and the upper plate 2.

[0021] Preferably, such as Figure 5 As shown, the first mounting part 9 is composed of multiple inverted frustums stacked coaxially. This structure forms a stepped profile that is narrow at the bottom and wide at the top, so that when the first mounting part 9 is inserted into the first mounting hole 5, the inclined surface of the inverted frustum can guide the first connector 6 to be smoothly inserted, reducing installation resistance. When it is subjected to outward pulling force, the expanded diameter step of the frustum produces a wedging effect with the wood on the side wall of the first mounting hole 5, which increases the contact area and frictional resistance, making it difficult to be pulled out and improving the connection reliability.

[0022] Preferably, such as Figure 5As shown, the upper side of the second mounting part 12 is provided with multiple second protruding rings 15 with triangular cross sections. The hypotenuse of the triangular protruding rings forms a 45° guide angle, which allows the second mounting part 12 to automatically center through the inclined surface when it is inserted into the second mounting hole 7, reducing the difficulty of installation. When the protrusion of the second protruding ring 15 is subjected to an outward force, its right-angled side is perpendicularly squeezed with the wood of the side wall of the second mounting hole 7, forming a large static friction force, making it difficult to be pulled out. Multiple vertical grooves 16 are distributed around the circumference of the second mounting part 12. The vertical grooves 16 can increase the elasticity of the component and allow a small radial deformation during installation, further improving the convenience of installation.

[0023] Preferably, the first mounting part 9 is interference-fitted with the first mounting hole 5; the second mounting part 12 is interference-fitted with the second mounting hole 7.

[0024] Preferably, such as Figure 4 As shown, the upper plate 2 is provided with handle grooves 18 on both sides, which facilitates the application of force by hand when the upper plate 2 is to be separated from the bottom plate 1.

[0025] Preferably, such as Figure 3 and Figure 4 As shown, the bottom surface of the receiving groove 3 is provided with a plurality of linearly distributed first expansion grooves 19; the lower end surface of the upper plate 2 is provided with a plurality of linearly distributed second expansion grooves 20. The first expansion grooves 19 and the second expansion grooves 20 are used to allow the material to freely extend or contract along the direction of the groove when the bottom plate 1 and the upper plate 2 are subjected to thermal expansion and contraction, thereby releasing internal thermal stress, preventing the board from cracking due to temperature changes, and improving the durability of the flooring system.

[0026] Working principle:

[0027] First, the phase change energy storage pack 4 is placed into the receiving groove 3 of the base plate 1, using the gap between it and the side wall of the receiving groove 3 to allow for thermal expansion. The phase change energy storage pack 4 stores and releases heat through a phase change process within a specific temperature range based on the principle of material phase change, thereby achieving temperature control. Next, the first mounting part 9 of the first connector 6 is inserted into the first mounting hole 5 of the base plate 1, and the second mounting part 12 of the second connector 8 is inserted into the second mounting hole 7 of the upper plate 2. Then, the upper plate 2 is aligned and connected with the base plate 1, so that the second cylinder 11 of the first connector 6 passes through the through groove 13 of the second connector 8, pushing open the first convex ring 14 with its inner wall tilting upwards, until the second cylinder 1... After full insertion, the first convex ring 14 returns to its original position under its own elastic force and abuts against the lower end face of the second cylinder 11, completing a quick and stable connection between the base plate 1 and the upper plate 2. When it is necessary to replace the aging phase change energy storage pack 4, hold the handle grooves 18 on both sides of the upper plate 2 with both hands and apply upward force to make the second cylinder 11 abut against the first convex ring 14 and move downward. The first convex ring 14 is pushed out. After the second cylinder 11 is completely pulled out, it returns to its original position and the upper and lower plates can be separated. In addition, the first expansion groove 19 on the bottom surface of the receiving groove 3 and the second expansion groove 20 on the lower end face of the upper plate 2 allow for a certain degree of extension when the base plate 1 and the upper plate 2 expand and contract with heat, preventing cracking.
