Abstract
The invention discloses an experimental device for distributing air volume of a refrigerator air duct. The experimental device comprises a centrifugal fan, a sliding baffle plate, a variable opening adjusting plate and a sliding track, wherein the sliding track is arranged to surround the centrifugal fan, and the sliding baffle plate and the variable opening adjusting plate both are mounted on the sliding track. According to the scheme of the experimental device, the sliding baffle plate and the variable opening adjusting plate are arranged to control the flow direction of cold air blast, controlling the flow of the cold air blast with the guide ribs of the refrigerator is simulated, and the sliding baffle plate and the variable opening adjusting plate are mounted on the sliding guide rail to realize optional sliding; according to the requirements of adjustment, the adjustment and control of the volume of the cold air blast can be realized by adjusting the sliding baffle plate and the variable opening adjusting plate, and therefore, the experimental device is very convenient to use.
Description
Technical field
The present invention relates to refrigerator field, is a kind of experimental provision of refrigerator air duct allocation of the amount of air specifically.
Background technology
In air channel between refrigerating chamber, temperature-changing chamber and the refrigerating chamber of wind cooling refrigerator, be provided with centrifugal blower, the mobile power that provides that centrifugal blower is cold wind in refrigerator compartment.Specifically, be provided with guiding rib at the periphery of centrifugal blower, the cold wind that guiding rib is sent centrifugal blower distributes, and flows to respectively each chamber of refrigerator according to the demand of design, thus the refrigeration of realization.Because the distribution of cold wind is not random, but will meet designing requirement, so when refrigerator is developed and assembled, debug the allocation situation of cold wind.The installation site of above-mentioned guiding rib directly has influence on the sendout of cold wind.At present, in the link of debugging, need to, according to actual debug results, repeat to change the fixed position of guiding rib, determine optimum mounting means, the very trouble that operates, and damage is caused in refrigerator inside air channel.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of experimental provision that is easy to the refrigerator air duct allocation of the amount of air that changes cold wind sendout, and it is simple in structure, can regulate and control to enter arbitrarily as required the amount of each chamber cold wind of refrigerator.
In order to solve the problems of the technologies described above, technical scheme provided by the invention is, a kind of experimental provision of refrigerator air duct allocation of the amount of air, comprise centrifugal blower, slide damper, variable openings adjustable plate and sliding rail, sliding rail is arranged in the periphery of centrifugal blower, and slide damper and variable openings adjustable plate are installed on sliding rail.
Compared to the prior art, in this programme, slide damper and variable openings adjustable plate are set and control cold wind and flow to, refrigerator guiding rib control cold flow is simulated, and slide damper and variable openings adjustable plate be arranged on rail plate, realize arbitrarily and sliding.According to the demand of debugging, just can realize the adjusting control to cold blast rate by controlling slide damper and variable openings adjustable plate, very convenient.
Described sliding rail is worm frame, and slide damper and variable openings adjustable plate are arc; The slide damper of arc and variable openings adjustable plate slide on the track of worm frame, effectively reduce the flow losses of cold wind, and make interior flow field speed even.
Described centrifugal blower comprises centrifugal impeller and motor, centrifugal impeller and motor linkage; Centrifugal blower adopts the simple centrifugal impeller of mechanism and motor combination, simple in structure, and the centrifugal effect of cold wind is better.
Angular marking post is set on described rail plate; Slide damper and variable openings adjustable plate need on rail plate, to slide within the specific limits, if according to range estimation, obviously can cause larger error, so angular marking post is set on rail plate, can determine more accurately their sliding position.
Slide damper is arranged on the inner side of rail plate, and variable openings adjustable plate is arranged on the outside of rail plate; Guarantee to slide non-interference.
Rail plate is provided with fixing hole; Can comparatively easily and by screw, rail plate be fixed on inner container of icebox securely.
Described angular marking post arranges 9; Angle between adjacent angular marking post is 30 °; Between angular marking post, be evenly provided with graduation mark; Angle between described graduation mark is 5 °; All the slips in order more rationally to control exactly slide damper and variable openings adjustable plate.
Accompanying drawing explanation

Fig. 2 is the horizontal layout schematic diagram of sliding rail in embodiment.
Fig. 3 is the disassemblying structure schematic diagram of embodiment.
In accompanying drawing, 1. slide damper; 2. variable openings adjustable plate; 3. centrifugal impeller; 4. motor; 5. angular marking post; 6. fixing hole; 7. sliding rail; 8. graduation mark.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is elaborated.
As shown in figs. 1 and 3, the present invention is on the basis of existing centrifugal blower, by slide damper 1 being set and variable openings adjustable plate 2 is mated, realizes the simulation that air channel volume is distributed.Specifically, this centrifugal blower is made up of centrifugal impeller 3 and motor 4, and be arranged on inner container of icebox, layout slide damper 1 around centrifugal impeller 3, slide damper 1 can say that the cold wind that centrifugal impeller 3 throws away is divided into two strands, one simulation enters refrigerating chamber, and another burst of simulation enters refrigerating chamber and temperature-changing chamber; Slide damper 1 need to be controlled the flow of two strands of cold wind as required, so should be set to adjustable.Based on this, rail plate 7 is set around centrifugal impeller 3, slide damper 1 is arranged on rail plate 7, realizes sliding effect.Wherein, rail plate 7 is preferably set to worm frame, and slide damper 1 is preferably set to arc, closely cooperates with rail plate 7.Type variable opening adjustable plate 2 is also housed on rail plate 7, and type variable opening adjustable plate 2 is preferably arc, and it is shunted the cold wind that enters refrigerating chamber and temperature-changing chamber again, and by controlling uninterrupted in the enterprising line slip of sliding rail 7.Rail plate 7 will be arranged on inner bag in advance, so fixing hole 6 is set on rail plate 7, is preferably symmetrical arranged a pair of (as Fig. 2), rail plate 7 effectively can be fixed on inner container of icebox like this.On rail plate 7, be also provided with angular marking post 5, its effect is accurately to control slide damper 1 and the slip amplitude of variable openings adjustable plate 2 on rail plate 7, the better demand that meets accurate control cold flow.The quantity of angular marking post 9 preferably arranges 9, and the angle at every adjacent two relative centrifugal impeller 3 centers is 30 °, evenly establishes graduation mark 8 between angular marking post, and between them, the angle at centrifugal impeller 3 centers is 5 ° relatively.
