Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
Refer to shown in Fig. 1, even temperature-changing chamber 100 of the present invention for refrigerator, described even temperature-changing chamber 100 comprise a room 10 and be contained in described between drawer 20 in room 10.
Refer to Fig. 1 and shown in composition graphs 2, Fig. 3 and Fig. 4, side wall 15, downside wall 16 that described room 10 comprises the opening 11 passed in and out for described drawer 20, the rear wall 12, the left side wall 13 being positioned at described rear wall 12 both sides and the right side wall 14 that are oppositely arranged with described opening 11 and arrange perpendicular to described left side wall 14, described rear wall 12, left side wall 13, right side wall 14, side wall 15 and downside wall 16 are enclosed to form a receiving space 17 jointly to accommodate described drawer 20.
Described side wall 15 is provided with some air outlets 151 to transporting cold wind in described drawer 20.The quantity of described air outlet 151 is odd number, and one is positioned at side wall 15 and passes in and out on the axis in direction at drawer 20, and remaining distributes in axis bilateral symmetry.Certainly, the quantity of described air outlet 151 also can be even number, and distributes in axis bilateral symmetry.In present embodiment, described air outlet 151 is specially three, one is positioned at side wall 15 and passes in and out on the axis in direction at drawer 20, two other distributes in axis bilateral symmetry, thus cold wind can be blown into bottom drawer 20 by these three air outlets 151, then cold wind upwards flows out to form cold air eddy current along drawer 20 sidewall again.
Described left side wall 13, right side wall 14 and rear wall 15 are respectively arranged with return air inlet 18, and described return air inlet 18 forms circulating cold air with air outlet 151 acting in conjunction to make drawer 20 inside.Described return air inlet 18 and the distance of downside wall 16 are less than its distance with side wall 15, and preferably, described return air inlet 18 as far as possible close downside wall 16 is arranged.
Refer to shown in 2, described drawer 20 comprises diapire 21 and some sidewalls 22, and described diapire 21, sidewall 22 are enclosed to form a storage space 23 jointly so that stored goods.The first gap 221 is formed between the top of described drawer 20 sidewall 22 and the side wall 15 of a room 10, and form the second gap 222 between the rear wall 12 of a room 10, left side wall 13 and right side wall 14, cold air confluxes to return air inlet 18 through the first gap 222, gap 221, second, thus makes to form circulating cold air between the rear wall 12 of drawer 20 and a room 10, left side wall 13 and right side wall 14.Described drawer 20 also comprise handle 24 in case described drawer 20 is pulled out described between the receiving space 17 of room 10.
When using even temperature-changing chamber 100 of the present invention, cold wind enters in described drawer 20 from described air outlet 151, and flow along the diapire 21 of described drawer 20 to the sidewall 22 of described drawer 20, and then flow along the sidewall 22 of described drawer 20 to the side wall 15 of room 10 between described, and through described first gap 221, second gap 222 is confluxed to return air inlet 18, thus make cold wind can arrive regional in described drawer 20 when described drawer 20 Inner eycle, the rear wall 12 of described drawer 20 and a room 10 simultaneously, also circulating cold air is formed between left side wall 13 and right side wall 14, and then realize fast, fully, the object of uniform decrease in temperature.In Fig. 1, Fig. 3, arrow is depicted as the flow schematic diagram of cold wind in described even temperature-changing chamber 100.
Even temperature-changing chamber 100 of the present invention by arranging some air outlets 151 to transporting cold wind in described drawer 20 in side wall 15, thus a large amount of cold wind can blow out from described air outlet 151 and form circulating cold air in drawer 20, and then described even temperature-changing chamber 100 can the drink such as Quick icing cooled beverage, beer, realizes the function of Quick icing.
Figure 5 shows that the second embodiment of the even temperature-changing chamber 200 of the present invention, the structure of described even temperature-changing chamber 200 is substantially identical with the structure of described even temperature-changing chamber 100, difference is that the return air inlet 28 of even temperature-changing chamber 200 is only arranged on left side wall 23, and air outlet 251 is arranged on the side of side wall 25 away from return air inlet 28.In other embodiments, return air inlet 28 can also only be arranged on right side wall 24 or downside wall 16.
Figure 6 shows that the 3rd embodiment of the even temperature-changing chamber 300 of the present invention, the structure of shown evenly temperature-changing chamber 300 is substantially identical with the structure of described even temperature-changing chamber 100, difference is that the return air inlet 28 of even temperature-changing chamber 300 is only arranged on rear wall 22, and air outlet 251 is arranged on the side of side wall 25 away from return air inlet 28.
Present invention also offers a kind of refrigerator, this refrigerator has supply air system, air return system and evenly temperature-changing chamber 100 or evenly temperature-changing chamber 200 or even temperature-changing chamber 300, the air outlet of described even temperature-changing chamber 100 or 200 or 300 is connected with supply air system, and return air inlet is connected with air return system.
Compared to prior art, even temperature-changing chamber 100,200,300 of the present invention can make cold air fully circulate, thus realizes object that is quick, abundant, uniform decrease in temperature, improves article preservation effect.
Of particular note, for the person of ordinary skill of the art, done for equivalence change of the present invention under the teachings of the present invention, must be included in the scope that the present patent application the scope of the claims advocates.
