Description

Technical Field

[0001] The utility model relates to the technical field of air energy water heating system components, in particular to a heat preservation water tank structure for an air energy water heating system. Background Art

[0002] Air-source hot water is also called "air source heat pump water heater". Its working principle is very similar to that of an air conditioner. It uses a small amount of electricity to drive the compressor. The high-pressure liquid working fluid evaporates into gas in the evaporator after passing through the expansion valve, and absorbs a large amount of heat energy from the air; the gaseous working fluid is compressed by the compressor into a high-temperature, high-pressure liquid, and then enters the condenser to release heat and heat the water. This continuous cycle of heating can heat the water to 5℃-65℃.

[0003] like Figure 5 As shown, this is the insulated water tank structure in the previous generation of air-energy water heating system. Its main function is to facilitate the heat exchange between the heat medium and cold water in the hot water system, and at the same time, the heated hot water can be insulated and stored. However, this type of insulated water tank structure has the following shortcomings in actual use: In order to improve the stability of the outer box body fixed on the mounting surface, a plurality of mounting ribs are generally fixedly connected to the lower end of the outer box body. During actual use, the outer box body is fixed to the mounting surface by mounting ribs and fasteners. This results in the need for operators to use tools to participate in the installation, disassembly, inspection and maintenance of the insulated water tank, which increases the difficulty and workload of the installation and removal of the insulated water tank, thereby reducing the convenience and efficiency of the installation and removal of the insulated water tank.

[0004] In view of this, it is particularly important to design and manufacture an insulated water tank structure that can realize quick installation and disassembly between the outer box body and the installation surface in the air-to-water heating system. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the traditional insulated water tank structure for air-energy water heating system and the installation and disassembly operations of the outer box body require the use of tools, resulting in poor convenience and low efficiency in the installation and disassembly operations of the insulated water tank, and propose an insulated water tank structure for an air-energy water heating system.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An insulated water tank structure for an air-energy water heating system comprises an outer box body, an inner box body arranged inside the outer box body, an insulating filling layer filled between the outer box body and the inner box body cavity, and a water outlet pipe, a water inlet pipe, a heat medium pipe and a sewage pipe installed from top to bottom at the right end of the inner box body and passing through the outer box body, a fixed disc seat coaxial with the outer box body is provided at the lower end of the outer box body, and a locking mechanism for placing the outer box body on the fixed disc seat for quick and tool-free fixation is provided between the lower end of the outer box body and the fixed disc seat.

[0008] As a further description of the above technical solution:

[0009] The locking mechanism includes a double-headed screw that passes through horizontally and is installed in the middle of the fixed disc seat, two inner threaded sleeves that are installed on the outside of the double-headed screw through symmetrical thread engagement, a sliding lock block installed on the outside of the two inner threaded sleeves, a limit lock buckle that is symmetrically fixed at the lower end of the outer box body and corresponds to the two sliding lock blocks, and a limit portion arranged between the outer box body and the fixed disc seat.

[0010] As a further description of the above technical solution:

[0011] The limiting part comprises four ground support blocks symmetrically installed on the left and right sides of the lower end of the outer box body and a limiting slot formed on the inner side of the fixed disc seat and buckled with the ground support blocks.

[0012] As a further description of the above technical solution:

[0013] An operating knob is installed on one end of the double-headed screw.

[0014] As a further description of the above technical solution:

[0015] The inner side of the fixed disc seat is provided with four mounting holes distributed at 90 degrees.

[0016] As a further description of the above technical solution:

[0017] The upper end of the fixed disc seat is equipped with a first rubber sealing ring that fits with the outer wall of the lower end of the outer box body, and the lower end of the fixed disc seat is equipped with a second rubber sealing ring that can fit with the installation surface.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] In the utility model, by scientifically and rationally improving the original outer box structure, a fixed disc seat, a double-headed screw and a sliding lock block are arranged at the lower end of the outer box body, and at the same time, a ground support block and a limit lock buckle are arranged at the lower end of the outer box body. The outer box body can be positioned downward by the ground support block and inserted into the limit slot of the fixed disc seat. Then, when the operating knob is held and turned, the two sliding lock blocks can slide into the limit lock buckle under the spiral transmission action between the double-headed screw and the inner threaded sleeve, thereby limiting and locking the outer box body on the fixed disc seat. This structure can realize tool-free quick installation and disassembly operations between the outer box body and the installation surface, effectively reducing the workload and difficulty of the actual installation and disassembly operations of the outer box body, thereby improving the convenience and efficiency of daily installation, disassembly, inspection and maintenance of the thermal insulation water tank.
