具体实施方式detailed description
图1是根据本发明一个实施例的风冷冰箱100的正视图。如图1所示，该风冷冰箱100一般性地可以包括：内胆110、送风风道120、送风管130、风门140、风机150以及冷源160。其中，送风风道120在内胆110上形成有主风道出风口121，以与内胆110限定的储物间室连通。FIG. 1 is a front view of an air-cooled refrigerator 100 according to an embodiment of the present invention. As shown in FIG. 1 , the air-cooled refrigerator 100 generally includes: an inner container 110 , an air supply duct 120 , an air supply pipe 130 , a damper 140 , a fan 150 and a cooling source 160 . Wherein, the air supply duct 120 is formed with a main air outlet 121 on the inner tank 110 to communicate with the storage compartment defined by the inner tank 110 .
风冷冰箱100的内胆110限定有储物间室，内胆110的背部设置有风道组件，限定有从冷源160延伸至储物间室的送风风道120。间室的数量以及结构可以根据需求进行配置，图1示出了上下依次设置的第一间室和第二间室；以上间室按照用途不同配置为冷藏间室、冷冻间室、变温间室或者保鲜间室。各个储物间室可以由分隔板纵向分割为多个储物区域，利用搁物架或者抽屉储存物品。The inner tank 110 of the air-cooled refrigerator 100 defines a storage compartment, and the back of the inner tank 110 is provided with an air duct assembly, defining an air supply duct 120 extending from the cold source 160 to the storage compartment. The number and structure of the compartments can be configured according to requirements. Figure 1 shows the first and second compartments arranged up and down in sequence; the above compartments are configured as refrigerated compartments, freezer compartments, and variable temperature compartments according to different purposes. Or fresh room. Each storage compartment can be divided longitudinally by a partition into multiple storage areas, using shelves or drawers to store items.
第一间室和第二间室共用一个冷源160和风机150，冷源160和风机150可以设置于第二间室内胆110背部的送风风道120。高温空气流经冷源160时，与冷源160充分进行热交换，空气的温度就会降低。同时，通过风机150强制冷风循环流动，将气流沿送风风道120送至各储物间室。风冷冰箱100通过这种不断的循环方式来降低风冷冰箱100的温度。第一间室所需要的冷风经由送风风道120由风机150送达，并通过风门140调节冷风风量。其中风门140可以设置于第一间室和第二间室之间的送风风道120内。The first room and the second room share a cold source 160 and a fan 150 , and the cold source 160 and the fan 150 can be arranged on the air supply duct 120 at the back of the second room inner liner 110 . When the high-temperature air flows through the cold source 160, it fully exchanges heat with the cold source 160, and the temperature of the air will decrease. At the same time, the cooling air is forced to circulate through the fan 150 , and the air flow is sent to each storage compartment along the air supply duct 120 . The air-cooled refrigerator 100 reduces the temperature of the air-cooled refrigerator 100 through this continuous cycle. The cold air required by the first room is delivered by the fan 150 through the air supply duct 120 , and the air volume of the cold air is adjusted through the damper 140 . Wherein the damper 140 can be arranged in the air supply duct 120 between the first room and the second room.
风冷冰箱的冷源可以采用冷媒循环系统的蒸发器或者半导体制冷片等制冷装置。The cold source of the air-cooled refrigerator can be an evaporator of the refrigerant circulation system or a refrigeration device such as a semiconductor refrigeration sheet.
图2、图3和图4分别是根据本发明一个实施例的风冷冰箱100的送风系统的示意图、A-A向剖视图以及B-B向剖视图。Fig. 2, Fig. 3 and Fig. 4 are a schematic diagram, a sectional view along the direction A-A, and a sectional view along the direction B-B, respectively, of the air supply system of the air-cooled refrigerator 100 according to an embodiment of the present invention.
风冷冰箱的储物间室内纵向设置有多个储物区域，送风风道120在每个储物区域具有一个或多个主风道出风口121，有利于每个储物区域都有冷风送达。送风风道120可以在每个储物区域设有一个或多个主风道出风口121，设置于每个储物区域内送风风道的中间位置。The storage room of the air-cooled refrigerator is provided with a plurality of storage areas vertically, and the air supply duct 120 has one or more main air duct air outlets 121 in each storage area, which is beneficial for each storage area to have cold air. service. The air supply duct 120 may be provided with one or more main air duct air outlets 121 in each storage area, which are arranged in the middle of the air supply duct in each storage area.
图2示出的储物间室内送风风道120为左右对称设计，在每个储物区域具有至少两个左右对称的主风道出风口121，这样可以使每个储物区域的送风更加有效，储物区域的温度更加均匀，更利于风冷冰箱100内的物品储存。The indoor air supply duct 120 of the storage room shown in Fig. 2 is a left-right symmetrical design, and each storage area has at least two left-right symmetrical main air duct air outlets 121, which can make the air supply of each storage area It is more effective, and the temperature in the storage area is more uniform, which is more conducive to the storage of items in the air-cooled refrigerator 100 .
如图2至图4所示，送风管130其第一端连通至送风风道120的主风道出风口121，其第二端从送风风道120沿内胆110弯折延伸至储物间室前部，以向储物间室前部供风。送风管130可以是实体管道，嵌设在内胆110外部的发泡层内。或者，送风管130还可以是内胆110本身形成凹槽，利用凹槽实现向储物间室前部供风的效果。As shown in Figures 2 to 4, the first end of the air supply pipe 130 is connected to the main air outlet 121 of the air supply duct 120, and the second end is bent from the air supply duct 120 along the liner 110 to the The front of the storage compartment to supply air to the front of the storage compartment. The air supply pipe 130 may be a solid pipe, embedded in the foam layer outside the liner 110 . Alternatively, the air supply pipe 130 can also be a groove formed in the inner container 110 itself, and the effect of air supply to the front of the storage compartment can be realized by using the groove.
每个主风道出风口121对应设置有一条送风管130，并且送风管130配置成引出主风道出风口121的至少部分风量。送风管130沿内胆110弯折延伸至储物间室前部，且送风管130的第二端在内胆110上形成有连通至储物间室内的支路出风口131。支路出风口131的送风方向配置成与内胆110侧壁呈倾斜角度，且朝向储物间室的后部。由于支路出风口131的送风方向并不直接相对，避免了因出风对吹发生的乱流。Each main air channel air outlet 121 is correspondingly provided with an air supply pipe 130 , and the air supply pipe 130 is configured to lead out at least part of the air volume of the main air channel air outlet 121 . The air supply pipe 130 bends along the inner container 110 and extends to the front of the storage compartment, and the second end of the air supply pipe 130 forms a branch air outlet 131 connected to the storage compartment on the inner container 110 . The air supply direction of the branch air outlet 131 is configured to form an oblique angle with the side wall of the inner container 110 and toward the rear of the storage compartment. Since the air supply direction of the branch air outlet 131 is not directly opposite, the turbulent flow caused by the blowing of the air outlet is avoided.
主风道出风口121的送风方向配置成与内胆110后壁呈倾斜角度，且朝向储物间室的前部，实现送风风道120和送风管130送出的冷风形成环流。如图4所示，实线箭头示出的是送风风道120送出的冷风，虚线箭头示出的是送风管130送出的冷风。送风风道120和送风管130送出的冷风在每个储物区域左右两部分都能形成环流，可以有效地对风冷冰箱的整个储物间室进行制冷，使得储物间室温度更加均匀。The air supply direction of the air outlet 121 of the main air duct is configured to form an oblique angle with the rear wall of the inner container 110 and towards the front of the storage compartment, so that the cold air sent by the air supply duct 120 and the air supply pipe 130 forms a circulation. As shown in FIG. 4 , the solid arrows indicate the cold air sent out from the air duct 120 , and the dotted arrows indicate the cold air sent out from the air duct 130 . The cold air sent by the air supply duct 120 and the air supply pipe 130 can form a circulation in the left and right parts of each storage area, which can effectively cool the entire storage compartment of the air-cooled refrigerator, making the temperature of the storage compartment more stable. uniform.
送风管130的第一端通过主风道出风口121连通至送风风道120内部，并且主风道出风口121的口径尺寸大于送风管130第一端的管径，以使部分冷风从主风道出风口121直接送出，另一部分经由送风管130向储物间室前部送风，实现了送风风道120和送风管130共同送风。使得风冷冰箱100储存间室内的送风更加有效，储存间室内的温度更加均匀，提高风冷冰箱100的储物效果，降低风冷冰箱100能耗。The first end of the air supply pipe 130 is connected to the inside of the air supply duct 120 through the air outlet 121 of the main air duct, and the diameter of the air outlet 121 of the main air duct is larger than the diameter of the first end of the air supply pipe 130, so that part of the cold air The air is directly sent out from the air outlet 121 of the main air duct, and the other part is sent to the front of the storage compartment through the air supply pipe 130, realizing the common air supply of the air supply duct 120 and the air supply pipe 130. The air supply in the storage room of the air-cooled refrigerator 100 is made more effective, the temperature in the storage room is more uniform, the storage effect of the air-cooled refrigerator 100 is improved, and the energy consumption of the air-cooled refrigerator 100 is reduced.
通过以上说明可以得出，本实施例的风冷冰箱100，设置有送风管130，作为送风风道120的辅助结构，使得风冷冰箱100储存间室内的送风更加有效，气流循环更加合理，更易于热量充分交换，提高了冰箱100的能源效率，并使冰箱100储存间室内的温度更加均匀，提高风冷冰箱100的储物效果。It can be concluded from the above description that the air-cooled refrigerator 100 of the present embodiment is provided with an air supply pipe 130 as an auxiliary structure of the air supply duct 120, so that the air supply in the storage room of the air-cooled refrigerator 100 is more effective and the air circulation is more efficient. Reasonable, easier to fully exchange heat, improve the energy efficiency of the refrigerator 100, and make the temperature in the storage room of the refrigerator 100 more uniform, and improve the storage effect of the air-cooled refrigerator 100.
