Abstract
The invention relates to a refrigerator doorframe structure. A heat insulating refrigerator body is remained with an installing space for installing a doorframe main body at a position corresponding to a magnetic door seal. One surface of the heat insulating refrigerator body facing to the installing space is provided with an interface board for sealing the heat insulating refrigerator body in a polyurethane integrally foaming forming process, the doorframe main body is fixed on the interface board, the outer surface of the doorframe main body is assembled with a magnetic absorption material, the doorframe main body is internally provided with an electric heating element placing cavity corresponding to the magnetic door seal, and an electric heating element is placed in the cavity. The invention has the main benefits of simplifying the preset process and being convenient for maintaining the electric heating element.
Description
Technical field
The invention belongs to refrigerator doorframe structure.
Background technology
At present, the incubator that is widely used in the refrigerator manufacturing adopts the polyurethane integral foaming technique to make more, and doorframe is participated in polyurethane integral foaming and molding technology with the insulation casing.For the sealing after strengthening that incubator and chamber door are entire and closing; To install the magnetic door strip of paper used for sealing of rubber or plastic material at insulation chamber door body additional; And the insulation casing in or install the adsorbable material of magnetic additional with magnetic door strip of paper used for sealing corresponding position in the doorframe; Also need or install the low-power heating additional with the gasket corresponding position in the doorframe in the insulation casing simultaneously, avoid refrigerator in use chamber door and casing freezed to cause incubator to be difficult to open, so before polyurethane integral foaming and molding technology; To in the insulation casing, pre-install heating and magnetic adsorptive material; This manufacturing technology exists and presets the technological operation complicacy, and heating can't take out maintenance behind the foaming and molding, cause refrigerator after the heating fault in use chamber door freezed the defective that can't repair.
Summary of the invention
In order to overcome the deficiency that technological operation complicacy, heating can't be keeped in repair that presets of existing refrigerator doorframe, the present invention provides a kind of simplification to preset technology, heating refrigerator doorframe easy to maintenance.
The technical solution adopted for the present invention to solve the technical problems is:
Refrigerator doorframe structure; It is characterized in that: said insulation casing is being used to install the installing space of described doorframe main body with the reservation of magnetic door strip of paper used for sealing corresponding position; Said insulation casing is provided with the interface board that is used at the described insulation casing of polyurethane integral foaming and molding technology sealing towards the one side of described installing space; Described doorframe main body is fixed on the described interface board, the outer surface of said doorframe main body assembling magnetic adsorptive material; Be provided with heating with magnetic door strip of paper used for sealing corresponding position in the said doorframe main body and place cavity, heating is placed in the described cavity.
As preferred a kind of scheme: the opening part that said heating is placed cavity is provided with interior capping.Through opening interior capping, heating is installed to heating places in the cavity.
Or: be provided with the installation cavity in the said doorframe main body; The bottom of said installation cavity is provided with installing hole; Securing member is installed in the said installing hole, and the opening part of said installation cavity is provided with inboard capping, and said installation cavity is placed cavity with said heating and is communicated with.Through opening inboard capping, the doorframe main body is installed in the insulation casing, and places connection place of cavity through cavity and heating are installed, heating is installed to heating places in the cavity.
Technical conceive of the present invention is: design a kind of doorframe of not participating in refrigerator incubator polyurethane integral foaming and molding technology; Comprise the doorframe main body; Said doorframe main body is fixedly connected with the insulation casing; In the doorframe main body, place electrical heating elements, at the outer surface assembling magnetic adsorptive material of doorframe main body.
Eliminated being incubated the preceding magnetic adsorptive material of casing polyurethane foam forming technology and the prepackage process of heating, thereby reduced the complexity of pre-assembled operational, improved operating efficiency.
Heating can disassemble maintain and replace from doorframe behind incubator polyurethane integral foaming and molding, avoided can not repairing because of the fault of heating chamber door is freezed, and influences the use of refrigerator.
Beneficial effect of the present invention mainly shows: 1, simplify and preset technology; 2, heating is easy to maintenance.
Description of drawings
Fig. 1 is the structural representation of refrigerator doorframe of the present invention.
Fig. 2 is the assembling sketch map of refrigerator doorframe.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 1, Fig. 2:
Refrigerator doorframe structure; Said insulation casing 5 is being used to install the installing space of described doorframe main body 1 with the reservation of magnetic door strip of paper used for sealing corresponding position; Said insulation casing 5 is provided with the interface board 6 that is used at the described insulation casing 5 of polyurethane integral foaming and molding technology sealing towards the one side of described installing space; Described doorframe main body 1 is fixed on the described interface board 6, the outer surface of said doorframe main body 1 assembling magnetic adsorptive material 4; Be provided with heating with magnetic door strip of paper used for sealing corresponding position in the said doorframe main body 1 and place cavity 3, heating 8 is placed in the described cavity 3.
Be provided with the installation cavity in the said doorframe main body 1, the bottom of said installation cavity is provided with installing hole, and securing member 7 is installed in the said installing hole, and the opening part of said installation cavity is provided with inboard capping 2, and said installation cavity is placed cavity with said heating and is communicated with.Through opening inboard capping 2, doorframe main body 1 is installed in the insulation casing 5, and places connection place of cavity through cavity and heating are installed, heating 8 is installed to heating places in the cavity 3.
Or: the opening part that said heating is placed cavity is provided with interior capping.Through opening interior capping, heating is installed to heating places in the cavity.
The doorframe of present embodiment comprises that doorframe main body 1, inboard capping 2, heating are placed cavity structure 3, magnetic adsorptive material 4 is formed.Interface board 6 links together with insulation casing 5 in polyurethane integral foaming and molding technology; Doorframe main body 1 links together through stressed joint firmware 7 and refrigerator insulation casing 5 behind the polyurethane foam forming technology; Again heating 8 being installed in heating places in the cavity structure 3; And snap onto on the doorframe main body 1 with inboard capping 2, magnetic adsorptive material 4 is connected on the doorframe main body 1, and be installed in magnetic door strip of paper used for sealing 9 on the body 10 through the magnetic force adhesive.
Keep in repair, change operation when needing repairing, can open when changing electrical heating elements 8 inboard capping 2.
Except that the foregoing description, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
