AI Technical Summary
In the defrosting process of existing cold storage, if there is a failure in the electric defrosting system, the electric heating tube needs to be replaced as a whole, which leads to high costs.
The electric heating module is spliced and disassembled, and the series connection of the heating wires is achieved through a conductive mechanism. Only the splicing pipe at the fault location needs to be replaced, which reduces maintenance costs.
This allows only the spliced pipe to be replaced in the event of a fault, avoiding the need to replace the entire electric heating module and reducing the maintenance cost of defrosting faults.

[0004] Therefore, in the prior art, electric heating is used to regularly defrost the inner wall of the cold storage. However, when electric defrosting is used, there is a problem: when a failure occurs, the electric heating tube needs to be replaced as a whole, and the overall replacement is costly.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figures 1 to 4In an embodiment of the present invention, a refrigeration device that is easy to defrost includes a cold storage 1, an indoor unit 2 is installed in the room of the cold storage 1, and the cold storage 1 is assembled by multiple insulation boards 101 and installed with keels. The insulation board 101 is provided with an installation groove 102, and the inner wall of the installation groove 102 is installed with an electric heating module 3.
[0023] In this embodiment: First, the prototype of the cold storage 1 is built by installing a light steel keel, and then the insulation board 101 is fixed (bolted) on the inside and outside of the keel to form an insulated cold storage 1. Since the insulation board 101 located on the inner side of the keel is provided with a mounting groove 102, the electric heating module 3 is then installed on the insulation board 101 through the mounting groove 102. The installed electric heating module 3 is electrically connected to the controller to realize the timed operation of the electric heating module 3. When the electric heating module 3 is in operation, it can convert electrical energy into thermal energy, and the thermal energy can melt the frost condensed on the inner wall of the cold storage 1, thereby achieving the defrosting effect.
[0024] Please refer to Figure 2 、 Figure 3 and Figure 4 The electric heating module 3 includes a splicing tube 301, a docking joint 302, a circular hole 303, a connecting thread 304 and a connecting nut 305; the splicing tube 301 is located in the inner cavity of the installation groove 102, and the docking joint 302 is integrally formed at the upper and lower ends of the splicing tube 301. The two docking joints 302 located on one splicing tube 301 are staggered front and back, and the connecting threads 304 are formed at both ends of the splicing tube 301 and the outer periphery of the splicing tube 301. The interior of the splicing tube 301 is a hollow structure, and the circular hole 303 is opened at the top and bottom ends of the splicing tube 301, and the circular hole 303 is connected to the inner cavity of the splicing tube 301. A conductive mechanism is provided on the two docking joints 302 at one end of the two splicing tubes 301. The splicing tube 301 is threadedly connected to the connecting nut 305 through the connecting thread 304 on the upper part of the outer wall thereof. The connecting nut 305 is used to connect the upper and lower adjacent splicing tubes 301.
[0025] In this embodiment: a plurality of splicing tubes 301 (straight tubes and U-shaped bends) are spliced one by one according to the track of the installation groove 102. During the splicing process, the docking joint at the bottom end of the upper splicing tube 301 is docked with the docking joint 302 at the top end of the lower splicing tube 301. After docking, the connecting nut 305 located at the bottom is rotated. The connecting nut 305 moves upward during the rotation. The connecting nut 305 rotates to tighten the two docking joints 302 in the docking state so that they fit tightly, thereby completing the connection of the upper and lower adjacent splicing tubes 301. In this way, the connection of the electric heating module 3 can be completed by splicing them one by one.
[0026] Please refer to Figure 3 and Figure 4The conductive mechanism includes a heating wire 4 installed on the inner wall of the splicing tube 301, and the two ends of the heating wire 4 respectively pass through the circular hole 303 and extend to the outside of the splicing tube 301.

[0027] In this embodiment: when the upper and lower docking joints 302 are docked, the two groups of conductive sheets 5 are in contact, and after the connecting nut 305 is tightened, the two groups of conductive sheets 5 are tightly fitted together. After the device is powered on, the conductive sheets 5 can be used to connect multiple heating wires 4 in series. The powered heating wires 4 convert electrical energy into thermal energy. The thermal energy is conducted to the splicing tube 301 through the crystalline magnesium oxide powder filled in the inner cavity of the splicing tube 301. The heat can act on the inner wall of the cold storage 1 through the splicing tube 301 to achieve a defrosting effect.
