Abstract
The utility model provides a sealing device used between an upper door and a middle door of a three-door refrigerator. A platform is arranged on the inner wall of the middle door. A turning plate is arranged on the platform. A rotating shaft and a rotating shaft hole are respectively and horizontally arranged on the platform and the turning plate. A guide groove is formed in the end surface of one end, far from a middle door spindle, of the turning plate. An opening is formed in one end of the guide groove. When the turning plate is horizontally placed, the opening faces the inside of the refrigerator, and the horizontal position of the opening is higher than the position of the other end of the guide groove. A guide pillar corresponding to the guide groove is arranged on the inner side wall of a refrigerator body, and when the turning plate is horizontally placed, the height of the opening is equal to that of the guide pillar. When both the upper door and the middle door are in a closed state, the turning plate is erected to block door cracks, and therefore loss of cold air in a refrigerating chamber can be reduced, and a refrigerating effect can be enhanced.
Description
Technical field
The utility model relate to a kind of for three-door refrigerator visit and the door between hermetically-sealed construction.
Background technology
Three-door refrigerator is provided with three of upper, middle and lower door body, is mainly that the alternating temperature refrigerating chamber is called again the zero degree fresh-keeping zone because the chill space of three-door refrigerator is divided into constant temperature refrigerating chamber and alternating temperature refrigerating chamber, and constant temperature refrigerating chamber correspondence is visited, door in alternating temperature refrigerating chamber correspondence.Although constant temperature refrigerating chamber and alternating temperature refrigerating chamber are two different spaces, but all be in a large cavity, dependence visit and middle door and casing between fit tightly and realize two refrigerating chambers are separated, and visit and middle door between crack between a door and its frame whether can play the effect of sealing, depend on the precision that mould is made fully.But due to factors such as refrigerator door material, machining accuracy and structural requirements, crack between a door and its frame is difficult to avoid, if visit or middle door fit to such an extent that tightness degree is bad with casing, cold air in refrigerating chamber will along visit and middle door between crack between a door and its frame run off, cause the refrigeration indoor air temperature to raise, the refrigeration system frequent starting expends the energy.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of for three-door refrigerator visit and the door between hermetically-sealed construction, when the He Zhongmen that visits is in closed condition, this hermetically-sealed construction can block crack between a door and its frame, reduces the loss of cold air in refrigerating chamber, improves cold storage effect.
The technical scheme that the utility model technical solution problem adopts is: this is used for, and hermetically-sealed construction between visiting of three-door refrigerator and door comprises casing, He Zhongmen visits, position at the close top edge of the inwall of described middle is provided with platform, be provided with turnover panel on described platform, a side near the door body on described platform and turnover panel has been horizontally disposed with respectively turning cylinder and shaft hole, and the distance between axle center and described turnover panel front end face is greater than described axle center and described distance of visiting between lower limb; Be provided with gathering sill on the end face of described turnover panel away from described middle every axle one end, an end of described gathering sill arranges opening, and when described turnover panel horizontal positioned, described opening points to refrigerator inside, and the horizontal level of described opening is higher than the other end of gathering sill; Be provided with the lead corresponding with described gathering sill on the madial wall of described casing, when described turnover panel horizontal positioned, described opening is identical with the height of lead.When closing middle door, gathering sill and lead coordinate erects turnover panel, blocks and visits and the gap between middle, reduces cold air and runs off.
In order to make lead can more successfully insert gathering sill and slide in gathering sill, the cross section of described lead is circular or oval, is provided with spigot surface at described opening part.
The beneficial effects of the utility model are: this hermetically-sealed construction that is used between visiting of three-door refrigerator and door arranges turnover panel on middle door inwall, improve and visit and the sealing effectiveness between middle, prevents that cold air runs off, and guarantees the function of refrigerating chamber.And the cooperation by gathering sill and lead, be that turnover panel can holded up at closing time automatically, play the effect of blocking crack between a door and its frame, and can automatically change the horizontal positioned state into when opening the door, can not affect normal use.
Description of drawings
Fig. 1 is the structural representation that the utility model is used for the hermetically-sealed construction between visiting of three-door refrigerator and door.
Fig. 2 is the structural representation that the utility model is used for the another kind of state of the hermetically-sealed construction between visiting of three-door refrigerator and door.
The specific embodiment
As depicted in figs. 1 and 2, on the inwall of middle door 3, platform 4 is set, turnover panel 5 is set on platform 4, platform 4 and turnover panel 5 are connected by the mode of turning cylinder and shaft hole, turnover panel 5 can rotate, distance between axle center and turnover panel 5 front end faces is greater than axle center and the distance between 2 lower limbs of visiting, like this after turnover panel 5 erects, just can shelter from visit 2 and middle door 3 between crack between a door and its frame.On the end face of turnover panel 5 away from middle door 3 door-hinge one ends, gathering sill 6 is set, an end of gathering sill 6 arranges opening 61, and when turnover panel 5 horizontal positioned, described opening 61 points to refrigerator inside, and the horizontal level of opening 61 is higher than the afterbody of gathering sill 5; Position corresponding with gathering sill 5 on the madial wall of casing 1 arranges lead 7, and when turnover panel 5 horizontal positioned, opening 61 is identical with the height of lead 7.
Like this, in the process of closing middle door 3, lead 7 slips in gathering sill 6 from opening 61, due to the opening 61 of gathering sill 6 higher than afterbody, the sidewall of lead 7 contacts with the upper wall of gathering sill 6, and along with middle door 3 continues to close, lead 7 promotes turnover panel 5 and rotates to vertical state from level.As shown in Figure 2, after central door 3 is closed fully, turnover panel 5 erect sheltered from visit 2 with middle door 3 between crack between a door and its frame, played the purpose of enhancing sealing effectiveness.
When needs are opened middle 3, lead 7 is interior to opening 61 places slip at gathering sill 6, the sidewall contact of the opposite side of lead 7 and gathering sill 6, along with middle door 3 continues to open, lead 7 promotes turnover panel 5 and rotates to level from upright state, and after lead 7 broke away from from gathering sill 6 fully, turnover panel 5 lay in a horizontal plane on platform 4, can not hinder normal use, and ready for again closing middle door 3.
A kind of better mode is, 61 places arrange spigot surface 62 at opening, even turnover panel 5 is not in the state of complete horizontal positioned, closing middle door at 3 o'clock, and spigot surface 62 also can guided lead 7 and slipped in gathering sill 6.And lead 7 is designed to the cross section is circular or oval-shaped structure, and lead 7 dynamics when promoting turnover panel 5 is softer, and more difficult scuffing material surface can not damage the user yet.
