Background technique
It is well known that refrigerating plant is that a kind of realized by heat exchange is freezed, and is reached by refrigeration and adjusted temperature or guarantor
The effects of dangerous；Existing refrigerating plant mainly includes the equipment such as air-conditioning, refrigerator-freezer；But circulating cold air inside existing refrigerating plant
Effect is bad to be easy to cause storage article local damage；When switching refrigerator door due to cold air in refrigerating plant and outside heat
Gas phase meets droplet easy to form, is that droplet congeals into ice drawer is be easy to cause to freeze closing refrigerator door.
It being found based on aforementioned present invention people, existing refrigerating plant is primarily present following deficiency, such as:
Indoor air circulation of freezing is bad, and partition can not achieve the perforation of air, and storage article is be easy to cause locally to damage
It is bad；When switching refrigerator door since cold air in refrigerating plant and external hot gas meet droplet easy to form, freeze closing
Device gate is that droplet congeals into ice drawer is be easy to cause to freeze.
Summary of the invention
In order to solve the above technical problem, the present invention provides circulating anti-freeze refrigerating plants, to solve existing system
Cold indoor air circulation is bad, be easy to cause storage article local damage；When switching refrigerator door due to refrigerating plant
Interior cold air and external hot gas meet droplet easy to form, are that droplet congeals into ice drawer is be easy to cause to freeze closing refrigerator door
The very few problem of the clinker of knot.
The purpose and effect of the circulating anti-freeze refrigerating plant of the present invention, are reached by technological means in detail below:
Circulating anti-freeze refrigerating plant, including cabinet body, the first refrigerating space, the second refrigerating space, supporting block, semicircle
Shape slot, limited block, drawer, semicircle item, the first refrigerating space air outlet, sliding groove, baffle plate device, rectangular channel, air hole, shield

B1102 and the second refrigerating space air outlet 12；The first refrigerating space 2 is offered in cabinet body 1 altogether and the second refrigerating space 3 two is cold
Hide space；First refrigerating space, 2 rear end face is provided with a first refrigerating space air outlet 8；The left side of first refrigerating space 2
Four groups every group two supporting blocks 4 are symmetrically arranged with right side, and the left side of the first refrigerating space 2 and right side are located at every group
The top position of supporting block 4 is symmetrically arranged with four groups every group two pieces of limited blocks 5；It is sliding between every group of supporting block 4 and every group of limited block 5
It is dynamic to be connected with a drawer 6；Second refrigerating space, 3 top end face is provided with a second refrigerating space air outlet 12, and second is cold
Hiding 3 left side of space and right side rectangular array shape are symmetrically arranged with three groups of sliding grooves 9；Sliding connects in every group of sliding groove 9
It is connected to one piece of baffle plate device 10；10 front end face of baffle plate device offers a rectangular channel 1001.
Wherein, supporting block 4 is trapezium structure, therefore the droplet formed when opening the door is not easy to stop in supporting block 4.
Wherein, the droplet for offering 20 semi-circular grooves 401 in supporting block 4, therefore being formed by switch refrigerating-chamber door can be from
Semi-circular groove 401 is discharged.
Wherein, 6 bottom face of drawer is symmetrically arranged with two semicircle items 7, therefore can reduce the contact of drawer 6 with supporting block 4
Area.
Wherein, the first refrigerating space air outlet 8 and the second refrigerating space air outlet 12 are venetian blind type air outlet, therefore can
Prevent cold air from directly blowing to chilled goods.
Wherein, 10 top end face of baffle plate device and bottom face offer several air holes 1002, therefore progress can be facilitated cold
Air-flow is logical.
Wherein, a barrier mechanism 11 is slidably connected in rectangular channel 1001, thus can be reduced when switching refrigerating-chamber door every
The loss of cold air in panel assembly 10.
Wherein, 11 bottom face of barrier mechanism is provided with several tapered protrusions A1101, and 11 left side of barrier mechanism and the right side
End surface symmetric is provided with three groups every group two tapered protrusion B1102, therefore can reduce barrier mechanism 11 and 1001 inner wall of rectangular channel

Knot.
Wherein, 1002 longitudinal cross-section of air hole is trapezium structure, therefore diffusion effect can be attached in the process of circulation of cold air.
When use: when cold air is discharged from the first refrigerating space air outlet 8 in the first refrigerating space 2, because of the first refrigeration
Space air outlet 8 is venetian blind type structure as shown in figure 11 therefore cold air can be spread to surrounding during cold air discharge, can prevent
The article that only cold air directly blows to storage causes article frostbite to damage, and is recycled in the first refrigerating space 2 after cold air discharge
Refrigeration；Because supporting block 4 is trapezium structure, therefore the droplet formed when opening the door is not easy to stop in supporting block 4；Because of supporting block 4
On offer 20 semi-circular grooves 401, therefore because the droplet that switch refrigerating-chamber door is formed can be discharged from semi-circular groove 401；Drawer 6
Bottom face is symmetrically arranged with two semicircle items 7, therefore can reduce the contact area of drawer 6 Yu supporting block 4, is existed by above-mentioned setting
Drawer 6 and supporting block 4 are mutually freezed after droplet can be avoided to freeze when switching refrigerating-chamber door to the greatest extent；
When cold air is discharged from the second refrigerating space air outlet 12 in the second refrigerating space 3, because of the second refrigerating space 3
For venetian blind type structure, therefore cold air can be spread to surrounding during cold air discharge, can prevent cold air from directly blowing to storage
Article causes article frostbite to damage, and is circulated after cold air discharge in the second refrigerating space 3, cold air during flowing
May pass through the air hole 1002 on baffle plate device 10 can facilitate to the contact of the uniform cold air in chilled goods periphery, improve cold storage effect；
The flowing velocity of cold air can be reduced because slidably connecting barrier mechanism 11 in baffle plate device 10 on the one hand, it is on the other hand cold in switch
The cold air that can effectively avoid in baffle plate device 10 when the door of hiding room is lost；11 bottom face of barrier mechanism is provided with several tapered protrusions
A1101, and 11 left side of barrier mechanism and right side are symmetrically arranged with three groups every group two tapered protrusion B1102, therefore can reduce
The contact area of barrier mechanism 11 and 1001 inner wall of rectangular channel can prevent barrier when temperature is lower than 0 degree in the second refrigerating space 3
Mutually freeze between mechanism 11 and rectangular channel 1001；1002 longitudinal cross-section of air hole is trapezium structure, therefore the stream in cold air passes through
Cheng Zhongke is attached to diffusion effect.
The embodiment of the present invention is given for the purpose of illustration and description, and is not exhaustively or by this to send out
It is bright to be limited to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Choosing
Selecting and describe embodiment is and to make those skilled in the art to more preferably illustrate the principle of the present invention and practical application
It will be appreciated that the present invention is to design various embodiments suitable for specific applications with various modifications.
