Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the side by side refrigerator provided by the present invention includes a freezing chamber (labeled in the figure) and a refrigerating chamber (labeled in the figure), wherein the freezing chamber and the refrigerating chamber are disposed adjacent to each other in the left-right direction. As shown in the drawing, the side by side refrigerator further has a freezing air duct 10 provided at the rear side of the freezing chamber, and an evaporator 12 and a defrosting heater 13 installed inside the freezing air duct 10, the defrosting heater 13 is generally provided at the lower side of the evaporator 12, and a freezing return air inlet 111 communicating the freezing chamber with the freezing air duct 10 is provided at the lower end of the freezing chamber rear wall 11. It is easy to understand that the evaporator 12 can provide the cooling capacity for refrigerating the freezing chamber and the refrigerating chamber when in operation, the defrosting heater 13 is used for heating the evaporator when the refrigerator is defrosted, and the freezing air return opening 111 is used for circulating the air in the freezing chamber back to the freezing air duct 10 and being cooled by the evaporator 12.
As shown in the figure, the side-by-side refrigerator according to the present invention further has a refrigerating return air duct 14, the refrigerating return air duct 14 provides air in the refrigerating chamber to circulate back to the freezing air duct 10, the refrigerating return air duct 14 has a refrigerating air inlet 141 communicated to the refrigerating chamber and a refrigerating return air inlet 142 communicated to the freezing air duct 10, wherein the position of the refrigerating return air inlet 142 and the position of the freezing return air inlet 111 have different horizontal heights. It will be appreciated that in practice, the refrigerated return air duct 14 is generally connected to the bottom space of the refrigerating compartment, and the refrigerated return air opening 142 and the refrigerated return air opening 111 are not located at a level higher than the top of the evaporator 12.
Based on the specific design structure of the side-by-side combination refrigerator provided by the invention, the position of the refrigerating return air inlet 142 and the position of the freezing return air inlet 111 have different horizontal heights, and return air entering the freezing air duct 10 from the freezing return air inlet 111 and the refrigerating return air inlet 142 respectively flows to different height positions of the evaporator 12, so that the problem that return air frosting is mainly concentrated at the bottom of the evaporator 12 in the prior art can be avoided, the defrosting period of the side-by-side combination refrigerator can be correspondingly prolonged, the temperature fluctuation frequency in a freezing chamber or a refrigerating chamber is reduced, and the energy consumption of the refrigerator is saved.
Referring to fig. 1, in the present embodiment, the freezing return air inlet 111 is located at a position corresponding to the bottom of the evaporator 12, and the refrigerating return air inlet 142 is located at a position corresponding to the middle of the evaporator 12. That is, the return air entering the freezing air duct 10 from the freezing air return opening 111 and the refrigerating air return opening 142 respectively flows to the bottom and the middle of the evaporator 12, during the specific cooling operation of the side-by-side refrigerator, the water vapor in the return air from the freezing air return opening 111 mainly frosts at the bottom of the evaporator 12, and the water vapor in the return air from the refrigerating air return opening 142 mainly frosts at the middle of the evaporator 12, it can be understood that in the present invention, the bottom of the evaporator 12 refers to the area close to and lower than the lower end of the evaporator 12, and the middle of the evaporator 12 refers to the area between the lower end of the evaporator 12 and the upper end of the evaporator 12. Based on the specific implementation structure of the embodiment, in the defrosting process of the side-by-side refrigerator, because the refrigerating return air inlet 142 is far away from the defrosting heater 13, the heat generated by the defrosting heater 13 cannot flow back to the refrigerating chamber through the refrigerating return air inlet 142, and therefore the refrigerating chamber hardly generates temperature fluctuation in the defrosting process of the side-by-side refrigerator.
Further, referring to fig. 1, the evaporator 12 has an evaporation tube 121 formed by bending back and forth, wherein the evaporation tube 121 has a plurality of straight tube sections 1210 arranged in parallel at intervals, in this embodiment, the distance d1 between two adjacent straight tube sections 1210 at the position of the refrigeration air return opening 142 is greater than the distance d2 between two adjacent straight tube sections 1210 at other positions.
It can be easily understood that the air humidity returned from the refrigerating return air inlet 142 is greater than the air humidity returned from the freezing return air inlet 111, and the manner of d1 being greater than d2 in this embodiment can make the evaporator 13 have a larger space for accommodating frost at the position corresponding to the refrigerating return air inlet 142. Further, the gap for air flowing at the position can be prevented from being blocked quickly by frost, and the defrosting period of the side-by-side refrigerator is further prolonged.
In a specific implementation process, the distance d1 between two adjacent straight pipe sections 1210 at the position of the refrigerated air return 142 is at least 1.5 times of the distance d2 between two adjacent straight pipe sections 1210 at other positions.
Referring to fig. 1, the evaporator 12 of the present invention also has fins 122 connected to the evaporating tubes 121. Preferably, the density of the fins 122 at the lower end of the evaporator 12 is lower than the density of the fins 122 at the upper end of the evaporator 12. This facilitates the upward flow of some of the water vapor in the return air and the formation of frost at the upper side of the evaporator 12, which makes the frost formation on the evaporator 12 more uniform.
Further, referring to fig. 2, unlike the embodiment shown in fig. 1, in the present embodiment, the refrigerating return air duct 14 has a plurality of refrigerating return air inlets 142 spaced apart in the height direction. Because a plurality of cold-stored return air inlets 142 are at different heights, can make the cold-stored return air more even blow to the not co-altitude region of evaporimeter 12, and then make the frost formation of cold-stored return air on evaporimeter 12 more even, can further optimize the defrosting control process of side by side refrigerator.
As shown in fig. 1 and fig. 2, the side-by-side refrigerator according to the present invention further includes a refrigerating air supply duct 15, the refrigerating air supply duct 15 includes a refrigerating air inlet 151 communicating with an upper space of the freezing air duct 10 and a plurality of refrigerating air supply outlets 152 communicating with the refrigerating chamber, and the plurality of refrigerating air supply outlets 152 are spaced apart in a height direction. Because a plurality of cold-stored supply-air outlets 152 set up in the direction of height at interval, the inside refrigeration that can more even realization walk-in of mode of so air supply mode compare the traditional walk-in top air supply.
In the implementation process, as shown in the figure, the side-by-side refrigerator further has a plurality of transverse partitions 16 arranged at intervals up and down to divide the refrigerating chamber into a plurality of storage spaces 17, and a plurality of refrigerating air outlets 152 correspond to at least two storage spaces 17. In this embodiment, each of the refrigerating air outlets 152 is correspondingly connected to one of the storage spaces 17.
In a preferred embodiment of the present invention, the refrigerating air duct 15 is embedded in the freezing air duct 10 on a side close to the refrigerating chamber. The problem that a traditional refrigerating air channel occupies the space of the refrigerating chamber or the freezing chamber can be avoided due to the arrangement, and the refrigerating chamber and the freezing chamber of the side-by-side combination refrigerator adopting the design have the largest volume under the same overall dimension.
As shown in the drawing, the side-by-side refrigerator also has a refrigerating damper 18 provided at the position of the refrigerating inlet 151. The refrigerating control of the refrigerating chamber can be realized by adjusting the opening degree of the refrigerating air door.
It can be understood that the side by side refrigerator according to the present invention further includes a fan 19 disposed in the freezing air duct 10, the freezing chamber rear wall 11 is further provided with a freezing air supply outlet 112 for communicating the freezing air duct 10 and the freezing chamber to allow cold air to flow out, when the fan 19 operates, air cooled by the evaporator 12 can flow to the freezing air supply outlet 112 and the refrigerating air inlet 151, and then respectively enter the freezing chamber and the refrigerating chamber.
The side by side refrigerator according to the present invention further has a vertical partition (not shown) for separating the freezing chamber and the refrigerating chamber, and preferably, as shown in the drawing, the refrigerating return duct 14 and the refrigerating supply duct 15 according to the present invention are disposed adjacent to one side of the vertical partition facing the freezing chamber and are disposed in the freezing duct 10. Therefore, the influence of the refrigerating return air duct 14 and the refrigerating air supply duct 15 on the storage capacity of the side-opening refrigerator can be avoided as much as possible.
