Description

Technical Field

[0001] The utility model relates to the technical field of multi-temperature zone anti-condensation for refrigerators, in particular to an intermittent multi-temperature zone anti-condensation aluminum foil heater for refrigerators. Background Art

[0002] Refrigerator condensation is a common phenomenon. When the refrigerator is used in summer or in a high temperature and high humidity environment, the moisture in the air will condense on the surface of the refrigerator shell and glass door due to the low temperature inside the box, forming bead-like condensation. The aluminum foil heater can evaporate the condensation by heating to achieve the purpose of removing the condensation in the refrigerator.

[0003] For example, the disclosure of the authorization announcement number CN206339008U discloses an aluminum foil heater for refrigerators, wherein a first adhesive layer is provided on one side of the aluminum foil, a heating wire is provided on one side of the first adhesive layer and adhered to the aluminum foil through the first adhesive layer, a first wiring card and a second wiring card are respectively connected to both ends of the heating wire, and the first wiring card and the second wiring card are respectively connected to metal terminals through wires. The aluminum foil heater for refrigerators with the above optimized design has a simple structure, and by arranging the heating wire on the aluminum foil, when heating, the aluminum foil is pasted to the position to be heated, so that large-area heating is achieved during heating, and it is easy to use. The aluminum foil greatly improves the heat dissipation effect of the heating wire and ensures uniform heating.

[0004] However, the aluminum foil heater mentioned in the patent is not suitable for use in the discontinuous partition of the refrigerator with multiple temperature zones because it is a single-layer heating. Since the multi-temperature zone partition needs to separate the two temperature zones, the aluminum foil heater needs to be responsible for eliminating the condensation generated in different temperature zones, which cannot be met by single-layer heating. At the same time, the existing aluminum foil heater is more troublesome to install and is not convenient to disassemble and assemble during subsequent repair and maintenance. Utility Model Content

[0024] Through the above scheme, the aluminum foil plate can be installed through the groove, and the heat generated by the aluminum foil heater can be reflected through the emitting sheet, while avoiding the temperature influence of different temperature zones. The aluminum foil heater can be clamped by rotating the clamping plate around the rotating pin, and the rotation and clamping are convenient for users to install and disassemble, and convenient for subsequent maintenance. The heating wire can be passed through the wire threading groove.

[0025] In this embodiment, preferably, the heating mechanism 102 includes an aluminum foil plate 204 movably mounted in the groove 105 , a heating wire 205 is fixedly mounted in the aluminum foil plate 204 , and the heating wire 205 is movably mounted in the threading groove 203 .

[0026] Through the above scheme, heat can be generated by energizing the heating wire, and the generated heat can be quickly conducted through the aluminum foil plate.

[0027] In this embodiment, preferably, the control mechanism 103 includes a controller 206 , a connecting plate 301 is fixedly installed at the rear end of the controller 206 , a connecting groove 302 is opened on the connecting plate 301 , and a connecting screw 303 is movably installed in the connecting groove 302 .

[0028] Through the above scheme, the controller can receive the temperature signal and control the heating condition of the heating wire, and the connecting plate can be installed by connecting screws penetrating the connecting groove, so that the controller is fixed.

[0029] In this embodiment, preferably, a heating wire 304 is fixedly installed at the bottom end of the controller 206 , a connecting block 305 is fixedly installed at the bottom end of the heating wire 304 , and a heating wire 205 is movably installed in the connecting block 305 .

[0030] According to the above solution, the heating wire and the heating wire can be connected through the connecting block, and the heating wire can be controlled to generate heat by energizing the heating wire.

[0031] In this embodiment, preferably, the left and right ends of the controller 206 are fixedly mounted with sensing wires 306 , the front end of the sensing wires 306 is fixedly mounted with a sensing sheet 401 , the middle of the sensing sheet 401 is fixedly mounted with a sensing module 402 , and the sensing sheet 401 is surrounded by a gluing area 403 .

[0032] Through the above scheme, the sensor sheet can be connected through the sensing wire, stable detection can be performed through the sensing module, and the sensor sheet and the partition can be adhered by injecting glue in the bonding area.

[0033] In this embodiment, preferably, an anti-breaking block 404 is fixedly installed on the top of the controller 206 , and a connecting wire 405 is fixedly installed on the top of the anti-breaking block 404 .

[0035] When using the intermittent multi-temperature zone anti-condensation aluminum foil heater for refrigerators of this embodiment, the user passes the heating wire 205 through the threading groove 203, and then places the aluminum foil plate 204 through the groove 105, and then twists the rotating clamping plate 201 to rotate around the rotating pin 202 and clamp the aluminum foil heater in the groove 105.

During the refrigeration process of the refrigerator, the sensor module 402 on the sensor sheet 401 monitors the temperature of the two separated temperature zones, and sends a signal to the controller 206 when the temperature change produces condensation. At this time, the controller 206 heats the heating wire 205 through the heating wire according to the temperature conditions of the different temperature zones, so that the aluminum foil plate 204 emits heat to evaporate the condensation on the partition. When the aluminum foil heater is heated, the temperature in the groove 105 is reflected by the reflective sheet 106, which increases the utilization rate of thermal energy and prevents the mutual influence of different temperature zones during heating. Therefore, the aluminum foil heater avoids the generation of condensation on the refrigerator partition.
