Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum foil heaters, and specifically relates to an aluminum foil heater with a temperature sensor for refrigerators. Background Technology

[0002] Aluminum foil heaters are lightweight, have high thermal conductivity, are energy-efficient, low-cost, durable, and environmentally friendly, and are commonly used for defrosting refrigerators. By heating the surface of the condenser or evaporator, they promote the rapid evaporation or melting of moisture on the surface, preventing the formation of frost. Frost formation leads to decreased heat exchange efficiency, causing the refrigerator to take longer to reach the set temperature. Aluminum foil heaters help remove frost, maintain the heat exchange efficiency of the condenser and evaporator, thereby reducing energy consumption and improving the refrigerator's energy efficiency.

[0003] However, existing aluminum foil heaters lack temperature control, and continuous heating may cause the temperature to become too high, affecting the refrigerator's cooling performance. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an aluminum foil heater with a temperature sensor for refrigerators, so as to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A refrigerator aluminum foil heater with a temperature sensor includes an aluminum foil and a main control board. A heating wire is heat-sealed onto the aluminum foil, and a sensor is attached to the aluminum foil. The heating wire and the sensor are connected in parallel on the main control board via wires.

[0007] As a preferred technical solution, a conductive connector is installed at each end of the heating wire and between each of the two sets of wires.

[0008] As a preferred technical solution, the connecting card is fitted with a double-walled tube, which is fixedly attached to the aluminum foil by tape.

[0009] As a preferred technical solution, the sensor is fixedly attached to the aluminum foil using adhesive tape.

[0010] As a preferred technical solution, it also includes a plug-in connector, on which terminals are installed, and all wires are electrically connected to the terminals. The main control board is also installed on the plug-in connector.

[0011] As a preferred technical solution, the plug-in connector includes a first sleeve and a second sleeve, which are plugged into each other. The terminal is installed on the first sleeve, and the main control board is installed on the second sleeve.

[0012] As a preferred technical solution, when sheath one and sheath two are plugged in, the terminals and the main control board are electrically connected.

[0013] As a preferred technical solution, the wire around the opening of the sheath is filled with sealant.

[0014] As a preferred technical solution, the aluminum foil includes a front side and a back side, with the heating wire and sensor both mounted on the front side, and double-sided adhesive tape attached to the back side of the aluminum foil.

[0015] As a preferred technical solution, another layer of aluminum foil can also be attached to the front of the aluminum foil, with the heating wire and sensor located between the two layers of aluminum foil.

[0016] Beneficial effects

[0017] The heating element is used for defrosting the refrigerator. A sensor detects the temperature and transmits the signal to the main control board via a wire. The main control board reads the sensor's resistance value and determines if the temperature is too high. If the temperature is too high, the main control board cuts off power to the heating element; if the temperature is too low, the main control board reconnects the heating element to resume heating. This intelligent temperature control prevents excessive heat from affecting the refrigerator's performance.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1

[0023] refer to Figure 1This embodiment describes an aluminum foil heater with a temperature sensor for refrigerators, comprising an aluminum foil 1, which has a front and a back side. The back side of the aluminum foil 1 is covered with double-sided adhesive tape 7, allowing customers to easily attach the heater to the corresponding position on the refrigerator, making it flexible and convenient to use. A heating wire 2 is heat-sealed onto the front side of the aluminum foil 1. A connecting clip 3 is installed at each end of the heating wire 2. A double-walled tube 4 for protecting the connecting clip 3 is fitted over the connecting clip 3. The double-walled tube 4 is fixedly attached to the front side of the aluminum foil 1 with tape 8. A sensor 5 is also attached to the front side of the aluminum foil 1 with tape 11. The device also includes a terminal 9 and a main control board 13. Both sets of connecting clips 3 and the sensor 5 are electrically connected to the terminal 9 via wires 6. A protective sleeve 10 is fitted over the terminal 9, and a protective sleeve 12 is fitted over the main control board 13. The terminal 9 and the main control board 13 are electrically connected through the insertion of the protective sleeve 10 and the protective sleeve 12. The sensor 5 and the heating wire 2 are connected in parallel. Heating wire 2 is used for defrosting the refrigerator. Sensor 5 senses the temperature and transmits the signal to the main control board 13 through wire 6. The main control board 13 reads the resistance value of sensor 5 and determines whether the temperature is too high. When the temperature is too high, the main control board 13 controls the heating wire 2 to cut off the power. When the temperature is too low, the main control board 13 controls the heating wire 2 to reconnect and reheat.

[0024] Preferably, the heating line 2 extends in a sinusoidal curve to increase the heating area.

[0025] It is worth noting that the connecting card 3 is a conductive metal sheet, preferably a copper sheet.

[0026] Preferably, both tape 8 and tape 11 are self-adhesive, which is environmentally friendly and facilitates the installation and adjustment of the double-wall tube 4 and the sensor 5.

[0027] Another layer of aluminum foil 1 can be attached to the front of aluminum foil 1 to protect heating wire 2 and sensor 5, etc.

[0028] The wire 6 at the opening of the sheath 10 is filled with sealant to prevent water from entering and causing a short circuit.
