Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a guide rail heating mechanism. Background Art

[0002] The refrigeration equipment has an inner tank, with rails on both sides of the inner tank and drawers between the rails. If the drawer of the refrigeration equipment is not pushed back after being opened for a long time, the rails that have been frozen at low temperatures will be exposed to room temperature for too long, and water droplets will easily condense on the surface of the pulled-out part of the metal rails. When the drawer is pushed back again, the rails will close, and the condensed water droplets on the rails will condense into ice, causing the customer to be unable to open the drawer due to the frozen rails when using the refrigeration equipment next time.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0007] A further technical solution is that the heating mechanism also includes: a contact switch, which is arranged at the rear end of the inner tank and is electrically connected to the brush; wherein, when the drawer is pulled out, the contact switch pops out to energize the inductor frame; when the drawer is pushed in, the drawer presses the contact switch to de-energize the inductor frame.

[0008] A further technical solution is that the heating mechanism further includes: a controller electrically connected to the contact switch, the brush and the power supply of the refrigeration equipment.

[0009] A further technical solution is that the heating mechanism further includes: a time delay relay connected between the controller and the brush, wherein the time delay relay is closed when the power is off and is disconnected after the power is on.

[0010] A further technical solution is that the heating mechanism also includes: an audible and visual alarm electrically connected to the controller.

[0011] A further technical solution is that the drawer comprises: grooves, which are opened on both sides of the drawer and whose positions correspond to the inductor frame; wherein the conductive coating is coated on the inner side of the groove, and the moving part is fixed on the inner side of the groove.

[0012] A further technical solution is that the heating mechanism comprises: an insulating coating, which is coated on the surface of the conductive coating and has a position corresponding to the moving part.

The magnetic field acts on the moving part passing through the inductor frame, and eddy currents are generated in the moving part. The eddy currents heat up the moving part, and after heating, the possibility of condensation of water droplets on the surface of the moving part is reduced, thereby ensuring that the drawer of the refrigeration equipment can be opened normally, thereby improving the user experience.

[0016] (ii) Furthermore, the heating mechanism also includes a contact switch arranged at the rear end of the inner tank, a controller electrically connected to the contact switch, and a time delay relay connected between the controller and the inductor frame.

Figure 5 It is an enlarged structural schematic diagram of a guide rail heating mechanism of the utility model. Figure 6 This is a connection diagram of a guide rail heating mechanism of the utility model.

[0029] like Figure 1 to Figure 6 As shown, in this embodiment, the guide rail heating mechanism is used for a refrigeration device. Exemplarily, the refrigeration device is a refrigerator.

[0030] The refrigeration device includes an inner tank 1, a guide rail 2 and a drawer 5. The inner tank 1 has a hollow structure. The guide rail 2 includes a support portion 21 and a moving portion 22. The support portions 21 are symmetrically arranged on both sides of the inner tank 1, the moving portion 22 is slidably arranged inside the support portion 21, and the drawer 5 is arranged between the moving portions 22. Exemplarily, the hollow structure is square, and the moving portion 22 is screwed to the side of the drawer 5.

[0031] The heating mechanism includes an inductor frame 3, a conductive coating 52 and an insulating coating 53. The inductor frame 3 includes a frame body 31 and a brush 32. The frame body 31 is arranged on both sides of the inner tank 1 and is in a semi-frame shape. The brush 32 is arranged at both ends of the frame body 31 and is connected to the power supply of the refrigeration device. The conductive coating 52 is coated on the surface of both sides of the drawer 5, and the position corresponds to the inductor frame 3. The insulating coating 53 is coated on the surface of the conductive coating 52, and the position corresponds to the moving part 22.

[0032] Exemplarily, the drawer 5 includes a groove 51, which is opened on both sides of the drawer 5 and corresponds to the position of the inductor frame 3. The conductive coating 52 is coated on the inner side of the groove 51, and the moving part 22 is fixed on the inner side of the groove 51. The setting of the groove 51 reduces the occupation of the drawer 5 space by the guide rail 2. The frame 31 can be made of conductive material, and the brush 32 is electrically connected to the power supply of the refrigeration equipment through the frame 31. Wires can also be buried in the frame 31, and the brush 32 is electrically connected to the power supply of the refrigeration equipment through the wire. The conductive coating 52 is rectangular, covering the sliding path of the brush 32, ensuring that the brush 32 is always in electrical contact with the conductive coating 52 when the drawer 5 is pulled out. The insulating coating 53 is rectangular, covering the contact part between the moving part 22 and the side of the drawer 5, preventing the guide rail 2 from being charged, and the user touching the guide rail 2 is electrocuted, thereby improving the safety of the refrigeration equipment. Preferably, the conductive coating 52 uses a conductive heating paint, and the insulating coating 53 uses a thermally conductive insulating material to improve the heating effect of the heating mechanism on the moving part 22.

[0033] Further, the heating mechanism also includes a contact switch 11 and a controller 4. The contact switch 11 is arranged at the rear end of the inner tank 1 and is electrically connected to the brush 32. The controller 4 is electrically connected to the contact switch 11, the brush 32 and the power supply of the refrigeration device respectively. The power supply of the refrigeration device supplies power to the controller 4. The controller 4 receives the signal of the contact switch 11 and supplies power to and cuts off power to the brush 32. Exemplarily, when the drawer 5 is pulled out, the contact switch 11 pops out, the controller 4 receives the signal of the contact switch 11, and supplies power to the brush 32; after the drawer 5 is pushed in, the drawer 5 presses the contact switch 11, the controller 4 receives the signal of the contact switch 11, and cuts off power to the brush 32. Preferably, the heating mechanism also includes a delay relay 41, which is connected between the controller 4 and the brush 32. The delay relay 41 is closed when the power is off, and is disconnected after the power is on, so that the inductor frame 3 stops heating, preventing the user from opening the drawer 5 for too long and the inductor frame 3 from being heated continuously, resulting in damage to the drawer 5 and excessive temperature in the refrigeration device, thereby ensuring user experience. The controller may be a commercially available on-off controller, and its control program belongs to the prior art.

[0034] Furthermore, the heating mechanism also includes an audible and visual alarm 42 , which is electrically connected to the controller 4 . When the drawer 5 is opened for a certain period of time, the controller 4 controls the audible and visual alarm 42 to sound an alarm.

[0035] When the drawer 5 is pulled out, the contact switch 11 pops out, the controller 4 receives the signal of the contact switch 11, and supplies power to the brush 32. The drawer 5 drives the moving part 22 to pass through the inductor frame 3, and the brush 32 of the inductor frame 3 slides in contact with the conductive coating 52. A magnetic field is generated between the inductor frame 3 and the conductive coating 52, and the magnetic field acts on the moving part 22 passing through the inductor frame 3, generating eddy currents in the moving part 22, which heats up the moving part 22. After heating, the possibility of condensation of water droplets on the surface of the moving part 22 is reduced, ensuring that the drawer 5 of the refrigeration equipment can be opened normally, and improving the user experience.

[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
