Description
Technical field
The invention belongs to refrigerating-chamber door Defrost technology field.
Background technology
Cold-storage door is the important composition department of freezer, and major function is to reduce loss of refrigeration capacity, it is allowed to which goods freely facilitates
Ground is stored and disengaging, while ensures the safety discrepancy of staff, and cold-storage door has a good heat-proof quality, door leaf and doorframe it
Between use the big special rubber seal rings for seal of compressibility.
Because cold storehouse temperature is very low, easily to freeze or frosting between the door leaf and doorframe of cold-storage door, cause cold
Ku Men stuck can not can not be opened.In order to prevent such case, existing cold-storage door is disposed with low-voltage electric heating in door leaf outer ring
Silk, heating after energization is so that frost is melted.The shortcomings that this cold-storage door Defrost method, is：When fault occurs for cold-storage door
（After heating wire overheat fusing）, the frost on freezing between the door leaf of cold-storage door and doorframe cannot be melted, cause cold-storage door
It can not open, such as now have personnel in freezer, in order to ensure personal security, it is necessary to which broken violence breaks down cold-storage door, although finally
Delay personnel are rescued, but cold-storage door is damaged and also brings along larger economic loss.
The content of the invention
It is cold not destroying the invention is intended to provide one kind the thermal source in the external world in cold-storage door circuit malfunctions, can be borrowed
On the premise of the door of storehouse, the method for fast melt frost.
A kind of cold-storage door Defrost method of this programme, comprises the following steps：
A., a kind of cold-storage door is installed in freezer door opening, the cold-storage door includes doorframe and door leaf, and affixed side and the doorframe of door leaf are cut with scissors
Connect, the free side of door leaf connects doorframe by door lock, is provided with installation cavity in the doorframe, is rotatably connected in installation cavity actively
Gear, cold-storage door are externally provided with the handle that control driving gear rotates；Be provided with inside the driving gear can external hot blast hot air cavity,
Exhaust vent is provided with the teeth groove of driving gear, the exhaust vent communicates with hot air cavity；Also it is sliding combined with the installation cavity vertical
Rack, be provided with drying cavity inside rack, the flank of tooth of rack engages with driving gear, is provided with and drying cavity phase on the tooth of the flank of tooth is convex
Logical fresh air inlet, the side away from the flank of tooth is provided with horizontal branch pipe on rack, and vertical movement is provided with the free side of door leaf
Groove, the branch pipe are slidably matched with shifting chute；The expanding block with annular is fixed with the branch pipe, the expanding block and branch pipe are coaxial,
The free end of expanding block flushes with door leaf free side；Horizontal U-shaped chamber is provided with inside expanding block, one end of the U-shaped chamber, which is slided, matches somebody with somebody
Conjunction has pressing plate, and the other end, which is provided with, seals with wax, and the U-shaped intracavitary is filled with water-absorption particle；The pressing plate connects close to the side of doorframe
It is connected to ice-cutter；
B. the external hot air source of hot air cavity, after exhaust vent, part hot blast enters in drying cavity hot blast from engaging piece along fresh air inlet, remains
It is remaining to enter from non-engaging piece in installation cavity, then enter from fresh air inlet in drying cavity；Blowed into the hot blast in drying cavity along branch pipe
Doorframe so that the frost of door leaf and doorframe is melted herein, and at the same time, expanding block is heated to be moved towards doorframe, heated melt of sealing with wax
After change, absorbing particles expand after absorbing the water of thawing, so as to promote pressing plate, ice-cutter towards doorframe move, horizontal broken this
Locate the frost not yet melted；
C. swing handle so that driving gear rotates, and drives the rack being engaged with to move down, under now branch pipe is in shifting chute
Move, ice-cutter also moves down and vertically splits trash ice frost, trash ice frost fast melt under the double action of thawing water and hot blast；Rack after
It is continuous to move down, until melting the frost between door leaf and doorframe completely.
Beneficial effect：By setting installation cavity in door leaf in the present invention, when being passed through hot blast to the hot air cavity of driving gear
Afterwards, part hot blast in engagement place along exhaust vent --- fresh air inlet enters in the drying cavity of rack, the process of this part hot blast
Path is shorter, and kinetic energy rejection is small, can be rapidly from the frost for intuitively blowing to door leaf free side so that frost is melted；Another portion
Hot blast is divided to enter in non-engagement place along exhaust vent --- installation cavity --- fresh air inlet in the drying cavity of rack, this part hot blast passes through
Path it is longer, and when hot blast is in installation cavity, rack outer wall can be heated, insulation effect be played to drying cavity, again finally
Enter drying cavity from fresh air inlet, swept along by the hot blast of speed and blow to frost.Cheng Shuizhong after frost is melted, pour and drench in lower section still
In the frost do not melted, now because expanding block moves with ice-cutter, water-absorption particle promotes ice-cutter from expansion after absorbing water
Stretched out in block, laterally split trash ice frost, and ice-cutter is driven when moving down, then splits trash ice frost, last these trash ices frost along vertical
In thawing water and hot blast double action fast melt.The present invention in cold-storage door circuit malfunctions, can borrow the thermal source in the external world
（Air-heater can be used, such as hair-dryer can be used to substitute without air-heater）, on the premise of cold-storage door is not destroyed, melt frost
And freezer is opened, avoid cold-storage door and be damaged violently the economic loss brought.
Further, the expanding block position between two parallel chambers of the U-shaped chamber is provided with horizontal chute, is slided in chute
Sliding shoe is combined with, the sliding shoe is fixedly connected with the pressing plate；Because sliding shoe is limited in chute, sliding block is connected with pressing plate,
It can prevent that pressing plate exits U-shaped chamber when water-absorption particle from expanding.
Further, blade is convexed to form on the ice-cutter face relative with doorframe, it is horizontal when being easy to ice-cutter transverse shifting
To the frost broken between door leaf free side and doorframe；The free end of ice-cutter is tip, is easy to ice-cutter to be erected by rack drives
To frost during movement, vertically rived between door leaf free side and doorframe.
Further, hollow hot blast axle is rotatably connected in the cavity wall of the installation cavity, the hot blast axle and driving gear key
Connection, and the wind regime hole communicated with hot air cavity is provided with the hot blast axle.The hot blast in the external world is introduced in hot air cavity by hot blast axle,
Hot blast enters in installation cavity or fresh air inlet after hot air cavity.
Further, the area of section at the place that seals with wax is less than the area of section of water-absorption particle, prevents water-absorption particle from sealing with wax
Deviate from space after thawing.
