Description
Technical field
The present invention relates to refrigerator-freezer technical field, and in particular to a kind of air-cooling type refrigerator.
Background technology
Existing air-cooled freezer is more using unilateral air-supply return air, and the position of air outlet is often on the top of refrigerating chamber close to cabinet mouth
Edge, theoretically wants to reach top air-supply bottom return air so as to form airflow circulating along inner wall in refrigerating chamber.It is air-cooled
The main advantage of formula refrigerator be frostless, chilling rate faster and refrigeration evenly, food fresh keeping is more preferable.
The Chinese patent of Patent No. CN200520109793 discloses a kind of air-cooling type refrigerator, the refrigerator-freezer include side wall,
Bottom wall, head cover, cold house and pressure wind circulating cooling system, it is characterised in that air outlet is provided entirely in same side wall with return air inlet
Upper and air outlet is arranged on the top of side wall, return air inlet is arranged on the bottom of same side wall, cold wind is formed in refrigerator-freezer very big
Recirculating zone.
The air-cooled refrigerator for return air form of blowing above, after space is frozen article occupancy in cabinet, is caused in refrigerating chamber
Circulating cold air can be affected, and cause the balanced refrigerating effect of overall (particularly core in cabinet) to be had a greatly reduced quality.Cause this
The reason for kind situation is that for return air all in same side wall, the circulation of air-flow is single, and user can not be avoided to make because it is blown
Stop the phenomenon of requisite space needed for air-supply return air caused by the personal habits of used time.
The content of the invention
The purpose of the present invention is for above-mentioned deficiency, it is proposed that a kind of design using crossings on different level air supply mode, allows cold
Air-flow is in refrigerating chamber according to the air-cooling type refrigerator of free nothing serious the circulation cycle of default route.
The present invention specifically adopts the following technical scheme that:
A kind of air-cooling type refrigerator, including the horizontal cabinet surrounded by left side wall, right side wall, front side wall, rear wall and bottom wall,
The top of horizontal cabinet is equipped with head cover, and the inside upper part of the right side wall is equipped with right side wall first layer air outlet, right side wall first
A diaphragm plate is equipped with layer air outlet, which is divided into two parts, the middle inside of right side wall up and down is equipped with right side
Wall second layer air outlet, is equipped with a vertical clapboard at right side wall second layer air outlet, which is divided into left and right two parts,
The top of horizontal cabinet is equipped with half hidden air passage, and half hidden air passage is equipped with corresponding front side wall air outlet and rear wall
Air outlet, the upper suspension of the horizontal cabinet have some barrier air passage basketrys, and each barrier air passage basketry is equipped with interior bottom and outside
Bottom, interior bottom and outer bottom form air passage in latticed between interior bottom and outer bottom, the air passage of each barrier air passage basketry connects shape
Into the insertion air channel of a right-to-left, the right side wall bottom is equipped with two main return air inlets of right side wall, and the lower part of right side wall is set
There are two right side wall pair return air inlets, right side wall pair return air inlet is convex relative to right side wall, and the bottom of forward and backward side wall is close to left
Side-walls are respectively equipped with forward and backward sidewall distal return air inlet;
When air-cooling type refrigerator carries out air-cooled circulation, front side wall air outlet uses opposite air supply mode to send with rear wall air outlet
Air-flow to blowing is formed at wind, top, and barrier air passage basketry upper area is cooled down;It is cold at right side wall first layer air outlet
Air-flow is divided into two layers up and down through diaphragm plate interval, and upper strata cold airflow blows obliquely upward, this layer of cold airflow is formed air curtain blocking
Exterior thermal current;Lower floor's cold airflow right-to-left, which is put down, blows into row cold airflow refrigeration, is blown with front side wall air outlet, rear wall air outlet
The cold airflow gone out is vertical and intersects;
The cold air of right side wall second layer air outlet blowout flows through vertical clapboard interval and is divided into left and right two parts, with front side wall outlet air
Mouth, rear wall air outlet are blown out distinguished and admirable vertical, and lower floor and the right side wall second layer air outlet of right side wall first layer air outlet are blown
The cold airflow gone out in the middle part of barrier air passage basketry with lower area to cooling down;
Cold airflow by front side wall air outlet, rear wall air outlet send out after again and via right side wall first layer air outlet, the right side
The cold airflow of the blowout of side wall second layer air outlet right-to-left is returned by forward and backward sidewall distal return air inlet and right side wall master together
Air port, right side wall pair return air inlet return, so as to be formed in horizontal counter body cold comprising little airflow and temperature equalization in big air-flow
Wind circulate, wherein, right side wall first layer air outlet, right side wall second layer air outlet right-to-left blowout cold air stream part warp
Insertion air channel diffuses to forward and backward sidewall distal return air inlet.
Preferably, barrier return air inlet is equipped with front side wall distal end return air inlet and rear wall distal end return air inlet and puts thing
Frame.
Preferably, top storage space, barrier air passage basketry and barrier return air are formed at the top of the barrier air passage basketry
Space between mouth rack forms lower part storage space.
Preferably, fan is equipped with the half hidden air passage, fan is arranged at right side wall first layer air outlet.
Preferably, the right side wall first layer air outlet includes two air outlets.
Preferably, the right side wall second layer air outlet includes two air outlets.
The present invention has the advantages that:When air-cooling type refrigerator carries out air-cooled circulation, front side wall air outlet and rear wall
Air outlet uses opposite air supply mode to blow, and the air-flow to blowing is formed at top, and barrier air passage basketry upper area is cooled down,
Right side wall first layer air outlet is blown with right side wall second layer air outlet by the way of right-to-left, and the cold airflow of blowout is to resistance
Cooled down in the middle part of the basketry of air passage with lower area, the design of the crossings on different level air supply mode in three layers of air passage, right side wall first
Cold air at layer air outlet flows through diaphragm plate interval and is divided into two layers up and down, and upper strata cold airflow blows obliquely upward, makes this layer of cold air
Stream forms thermal current outside air curtain blocking.
The air passage formed in barrier air passage basketry between bottom and outer bottom, ensures that cold airflow is without hindrance from dextrad in cabinet
Left circulation can protect upper strata air outlet not to be stored article blocking so as to reach while good circulating effect.
Obstruct air passage basketry and form top storage space, obstruct air passage basketry and obstruct the space between return air inlet rack
Lower part storage space is formed, coordinates forward and backward side wall return air inlet and right side wall return air inlet, no matter how user carries out the pendulum of article
Put, can ensure cold airflow in refrigerating chamber according to free nothing serious the circulation cycle of default route so that by air-cooled cold
The advantage of cabinet maximizes, and blocking return air inlet is made caused by multiple, three-dimensional air return method can solve user's use habit
Into return air it is bad the problem of.
