Accompanying drawing explanation
Fig. 1 is the inner structure schematic diagram that the utlity model has the antistaling container of chilled nitrogen function processed.
The specific embodiment
For the technical solution of the utility model can more clearly be showed, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, for the antistaling container with chilled nitrogen function processed of the utility model one preferred embodiment, this antistaling container with chilled nitrogen function processed comprises controller 20, Air compressor 30, cooling driers 40, the nitrogen making machine 60 of a cold chamber 11, reefer 12, connection successively; This cooling driers 40 comprises an air filter 51 and a refrigerating compressor 50, and this refrigerating compressor 50 connects described cold chamber 11 and reefer 12, out hyperphoric to move the heat of cold chamber 11 and reefer 12.The nitrogen of described nitrogen making machine 60 outputs is carried toward cold chamber 11, reefer 12 and an outer end interface 13 respectively.
Described cold chamber 11 and reefer 12 are high voltage bearing sealing grid, can extract accommodating food.The outside face of this cold chamber 11 is provided with a ventilative button 81, after this ventilative button 81 is pressed, the inside of cold chamber 11 is in communication with the outside, thereby discharges inner air pressure.Interior one first pressure sensor 21 that arranges of this cold chamber 11, this first pressure sensor 21 connects described controller 20; On the pipeline of the described cold chamber 11 of described nitrogen making machine 60 connection, one first electromagnetic valve 71 is set, this first electromagnetic valve 71 connects described the first pressure sensor 21; When the air pressure of cold chamber 11 is during lower than a threshold values, the air pressure that this first pressure sensor 21 detects this cold chamber 11, lower than threshold values, starts this controller 20 Air compressor 30 and nitrogen making machine 60 is communicated with extraneous power supply 10.
The outside face of this reefer 12 is provided with a ventilative button 82, after this ventilative button 82 is pressed, cold reefer 12 is in communication with the outside, thereby discharges inner air pressure.Interior one second pressure sensor 22 that arranges of this reefer 12, this second pressure sensor 22 connects described controller 20; On the pipeline of the described reefer 12 of described nitrogen making machine 60 connection, one second electromagnetic valve 72 is set, this second electromagnetic valve 72 connects described the second pressure sensor 22; When the air pressure of reefer 12 is during lower than a threshold values, the air pressure that this second pressure sensor 22 detects this reefer 12, lower than threshold values, starts this controller 20 Air compressor 30 is communicated with extraneous power supply 10.
Described outer end interface 13 is provided with a switch valve 23, and this switch valve 23 connects described controller 20, when switch valve 23 is opened, starts this controller 20 simultaneously Air compressor 30 is communicated with extraneous power supply 10.
During work, refrigerating compressor 50 continuous firings of described cooling driers 40, to freeze to described cold chamber 11 and reefer 12.When described cold chamber 11 and reefer 12 equal closure, described the first pressure sensor 21, the second pressure sensor 22 detects cold chamber 11, the air pressure of reefer 12 is during lower than threshold values, start controller 20, Air compressor 30 energisings are started, thereby Air compressor 30 pressurized airs are through cooling driers 40, after air filter 51, enter nitrogen making machine 60, the nitrogen of food stage is provided to cold chamber 11 and reefer 12 by nitrogen making machine 60, until cold chamber 11, air pressure in reefer 12 all reaches after the threshold values of setting, the first pressure sensor 21, the second pressure sensor 22 all sends closing signal to controller 20, simultaneously because switch valve 23 is also when the closed condition, now make controller 20 close.That is to say, described the first pressure sensor 21, the second pressure sensor 22, switch valve 23 are signal in parallel at three kinds of control signals of controller 20, when the first pressure sensor 21, the second pressure sensor 22, switch valve 23 are all closing signal, 20 of controllers are in closed condition; In the first pressure sensor 21, the second pressure sensor 22, switch valve 23, any one is opened, and controller 20 is in opening.
When user need to extract cold chamber 11, first press ventilative button 81, the high pressure nitrogen in cold chamber 11 is emitted, reduced the air pressure in cold chamber 11, then closed again after cold chamber 11 extractions are taken to food.Now, described the first pressure sensor 21 measures air pressure in described cold chamber 11 lower than threshold values, to controller 20, transmit start signal, open the first electromagnetic valve 71 simultaneously, automatically to start Air compressor 30 and nitrogen making machine 60 to cold chamber 11 inflated with nitrogen, until the air pressure in cold chamber 11 stops inflated with nitrogen by the first pressure sensor 21 by controller 20 control Air compressors 30 and nitrogen making machine 60 after reaching threshold values, and close the first electromagnetic valve 71.
In like manner, when user need to extract reefer 12, the second pressure sensor 22 is controlled the first electromagnetic valve 71 and controller 20 according to the pressure variation in reefer 12, thereby control Air compressor 30 and nitrogen making machine 60 to reefer 12 inflated with nitrogen or stop inflated with nitrogen, reach the nitrogen pressure in self-equalizing reefer 12, guaranteed food in environment freezing, that be full of nitrogen.
When this antistaling container with chilled nitrogen function processed provides food stage nitrogen to the external world separately by outer end interface 13, only need to press switch valve 23,23 of switch valves control Air compressors 30 by controller 20 and nitrogen making machine 60 is inflated, by outer end interface 13 to extraneous inflated with nitrogen.
The antistaling container with chilled nitrogen function processed of the present utility model, by the interior Air compressor of establishing 30, cooling driers 40, nitrogen making machine 60 nitrogen processed, cold chamber 11, the reefer 12 that simultaneously utilizes 40 pairs of cooling driers to store food inflated with nitrogen carries out freezing, guaranteed that food is fresh-keeping under environment freezing, that be full of nitrogen.In addition, by the first pressure sensor 21, the second pressure sensor 22, switch valve 23, in conjunction with controller 20, reach the effect of automatic nitrogen-charging gas, convenient and practical.
The above embodiment has only expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
