Abstract
The utility model discloses an ultralow temperature refrigeration storage bin with balanced internal and external air pressures, which is characterized in that the bottom of a casing is equipped with a ventilation pipe passing through the interior and the outside of the casing. The orifice of the ventilation pipe is equipped with a silicone rubber choke plate and the intermediate of the silicone rubber choke plate is equipped with a breach. Since the ventilation pipe passes through the interior and the outside of the casing of the ultralow temperature refrigeration storage bin, no negative pressure exists in the storage bin. Therefore, the door of the storage bin can be opened normally and is prevented from deforming and being damaged.
Description
Technical field
The utility model relates to a kind of superfreeze storage bin.
Background technology
In use there is a problem in superfreeze storage bin in the prior art: open the door each time and all can in casing, introduce surrounding air, after closing the door, owing to be refrigerating environment in the casing; This makes the gas volume that is enclosed in the casing dwindle; The case internal gas pressure reduces, and chamber door is tightly inhaled on casing, not only causes the secondary opening difficulty; More the reduction because of the casing internal gas pressure causes an envelope and door shell compressive deformation, and long-time use then causes the deformed damaged of a body component.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point; A kind of superfreeze storage bin of inside and outside air pressure balance is provided; To solve the problem of superfreeze storage bin secondary opening difficulty, avoid causing an envelope and door shell compressive deformation because of the reduction of casing internal gas pressure.
The utility model technical solution problem adopts following technical scheme:
The design feature of the superfreeze storage bin of the utility model inside and outside air pressure balance is the permeability cell inside and outside the bottom of casing is provided with a perforation casing; One silicon rubber chock flap is set on the mouth of pipe of said permeability cell, has a breach in the centre of said silicon rubber chock flap.
The design feature of the superfreeze storage bin of the utility model inside and outside air pressure balance also is:
Said permeability cell is mounted in one and connects in the inside and outside sleeve pipe of casing.
In-built electrical heat pipe in said permeability cell.
On the outside mouth of pipe of permeability cell, accept one section protecting pipe, the bottom of protecting pipe is provided with a base plate, and said silicon rubber chock flap is installed on the base plate.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model forms perforation with permeability cell inside and outside the casing of superfreeze case, makes no negative pressure in the case, and Men Tike normally opens, and has also avoided the distortion and the damage of door body simultaneously.
2, the utility model is simple in structure, easy to implement.
Description of drawings
Fig. 1 is the utility model structural representation.
Label among the figure: 1 casing; 2 bodies; 3 permeability cells; 4 sleeve pipes; 5 permeability cell base plates; 6 electrothermal tubes; 7 silicon rubber chock flaps; 8 protecting pipes.
The specific embodiment
Referring to Fig. 1; In the present embodiment superfreeze storage bin of inside and outside air pressure balance be at casing 1 the bottom, near the side at door body 2 place be provided with one connect casing 1 inside and outside permeability cell 3; One silicon rubber chock flap 7 is set on the mouth of pipe of permeability cell 3; Have a breach in the centre of silicon rubber chock flap 7, stop gas flow, prevent cold draining with silicon rubber chock flap 7; When casing 1 internal gas pressure reduces, under the effect of air pressure, there is the breach on the silicon rubber chock flap 7 to open, replenish gas in the casing, make the casing internal and external pressure balance.
In the practical implementation; Be that permeability cell 3 is installed in the sleeve pipe 4 that connects inside and outside the casing; And in-built electrical heat pipe 6 in permeability cell 3, the power of electrothermal tube 6 are 10 watts, and permeability cell 3 employing diameters are 20 millimeters stainless steel tube; In the use, heat in case the pore of permeability cell is stopped up by frost with in-built electrical heat pipe 6.
For the ease of assembling, accept one section protecting pipe 8 on the outside mouth of pipe of permeability cell 3, the bottom of protecting pipe 8 is provided with a base plate 5, and silicon rubber chock flap 7 is installed on the base plate 5.
