Abstract
Description
Technical Field
[0001] This utility model relates to a heat tank, and more particularly to a novel insulated heat tank, as well as to a water purification device having the insulated heat tank. Background Technology
[0002] Household water purifiers, categorized by hot water supply mode, typically include instant-heating modular water purifiers, hot-tank heating water purifiers, and dual-module hot-tank / instant-heating water purifiers. Hot-tank heating water purifiers feature an insulated hot tank from which users can draw water at any time. To maintain the hot tank's temperature, an insulation layer is usually installed on the outside of the tank. Existing insulation layers include rubber-plastic cotton layers, polyurethane foam layers, or vacuum insulation layers. However, rubber-plastic cotton layers and polyurethane foam layers have relatively weak insulation performance, resulting in significant heat loss. Adding a vacuum insulation layer, on the other hand, significantly increases the manufacturing cost of the hot water tank.
[0003] Therefore, further improving the heat preservation capacity of the heating element is a technical problem that needs to be solved in this field. Utility Model Content
[0004] The purpose of this invention is to overcome the defects of the existing technology and provide a heat preservation tank that is simple in structure, easy to manufacture, and has better heat preservation performance, which can be applied to household water purifiers or commercial water purifiers.
[0005] To achieve the above objectives, this utility model provides a novel heat-insulating hot tank, which includes a tank body 1 and a hot tank inlet 2 and / or a hot tank outlet 3 disposed on the tank body 1. The outer side of the tank body 1 has a heat-insulating layer, which is a porous vacuum silicon layer 11.
[0006] In this invention, the porous vacuum silicon (Porous Si) is a novel one-dimensional nanophotonic crystal material with a "quantum sponge"-like microstructure based on nano-silicon atom clusters. It can be formed by electrochemical anodic etching or chemical etching of single-crystal silicon. For example, porous vacuum silicon materials sold by Shenzhen Meixing New Materials Technology Co., Ltd. can be used.
[0007] In this invention, the thermal conductivity of the porous vacuum silicon is 0.012-0.014 W / (m·K). Due to its low thermal conductivity, the porous vacuum silicon layer can exhibit superior thermal insulation performance. In contrast, the thermal conductivity of conventional polyurethane foam is approximately 0.024 W / (m·K), and the thermal conductivity of rubber and plastic insulation cotton is typically 0.034–0.041 W / (m·K).
[0008] In a preferred embodiment, the porous vacuum silicon layer 11 has a thickness of 5mm to 7mm. The cut porous vacuum silicon sheets can be pressed tightly against the outer layer of the heat sink and fixed together by adhesive.
[0009] As a preferred embodiment, a protective layer may be further provided on the outside of the porous vacuum silicon layer 11, for example, using aluminum foil tape to construct the protective layer.
[0010] In this invention, the porous vacuum silicon layer 11 is disposed on the outer side of the wall of the tank 1 and the outer side of the top of the tank 1.
[0011] In a preferred embodiment, the insulated heating tank also has a heating tank mounting base 4 that matches the insulated heating tank. The heating tank mounting base 4 facilitates fixing the insulated heating tank inside the water purification equipment. Optionally, a heating tank outlet passage can also be provided in the heating tank mounting base 4, and the port of the heating tank outlet passage can be connected to the heating tank outlet 3.
[0012] This utility model also provides a water purification device having the above-mentioned insulated heat tank.
[0013] This invention uses porous vacuum silicon material as the insulation layer of the hot tank, which enables a single-layer hot tank to achieve the same insulation effect as a vacuum hot tank with a double-layer structure. Therefore, it simplifies the complexity of water purification equipment and effectively reduces production costs. Attached Figure Description

[0015] Figure 2 This is a left view of the insulated heat tank in Example 1. Detailed Implementation
[0016] The following embodiments are used to explain the technical solution of this utility model in a non-limiting manner.
[0017] like Figure 1 The heat preservation tank shown is a cylindrical tank 1 with a volume of 5L made of stainless steel. A porous vacuum silicon layer 11 with a thickness of 5mm is provided on the outer side wall and the outer side top of the tank.
[0018] A hot water inlet 2 and a hot water outlet 3 are installed on the upper part of the tank body 1. The insulated hot water tank is installed on a matching hot water tank mounting base 4. The hot water outlet 3 is connected to the hot water pump 5 through a passage in the hot water tank mounting base. 95℃ hot water is injected into the hot water tank. After keeping it warm for 6-7 hours, the temperature change of the hot water tank insulation layer is measured.
[0019] As a control, hot tanks with the same volume were manufactured, and insulation layers were made of 5mm thick rubber-plastic insulation cotton and 5mm thick polyurethane foam material, respectively.
[0020] The test results are shown in Table 1.
[0021] Table 1: Comparison of Temperature Rise Tests for Several Insulation Materials (Same Model)
[0022]
[0023] The results show that the insulation layer of this invention has the smallest temperature rise, indicating that its insulation function is superior to that of the prior art.
[0024] In addition, the power consumption of three types of insulated heat tanks was tested by changing different insulation materials on the same machine, and compared with vacuum heat tanks with double-layer structures commonly used in existing technologies. The results are shown in Table 2.
[0025] Table 2: Comparison of power consumption and shell temperature rise of several insulation materials
[0026] Thermal insulation materials 24-hour power consumption (kW·h) The outer casing temperature rises (K). Porous vacuum silicon 0.58 13 Vacuum heating element 0.58 17 polyurethane foam 0.72 18 Rubber and plastic cotton 0.79 19
[0027] The results show that porous vacuum silicon material has low 24-hour power consumption, meaning it is more energy-efficient than other insulation materials, thus extending the overall lifespan of the water purification equipment. This invention utilizes porous vacuum silicon material as the insulation layer for the heating tank, enabling a single-layer heating tank to achieve the same insulation effect as a double-layer vacuum heating tank, thereby simplifying equipment complexity and effectively reducing production costs.
