Description

冰箱refrigerator

技术领域technical field

本发明涉及冷藏冷冻技术，特别是涉及一种冰箱。The invention relates to refrigeration and freezing technology, in particular to a refrigerator.

背景技术Background technique

随着人民生活水平的提高，对食材的存放更为精细。目前市场中干湿分储的空间大都为单独的固定区域，但是，用户在不同的季节对干湿区的需求往往不同，有的季节不需要干区，有的季节不需要湿区，而有的季节干湿区都需要，这样就造成部分分区空间在某些季节将失去作用，造成冰箱的空间浪费。为此，现有技术中出现了一种具有干湿可调抽屉的冰箱，以根据用户的不同需求储存湿度要求不同的食材。With the improvement of people's living standards, the storage of food materials is more refined. At present, most of the space for dry and wet storage in the market is a separate fixed area. However, users often have different needs for dry and wet areas in different seasons. Some seasons do not need dry areas, some seasons do not need wet areas, and some Both dry and wet areas are required in different seasons, which will cause some partition space to be useless in certain seasons, resulting in waste of refrigerator space. For this reason, a kind of refrigerator with dry-wet adjustable drawer appeared in the prior art, to store food materials with different humidity requirements according to different needs of users.

这种冰箱通常通过向抽屉内输入流经蒸发器后的冷却气流实现干燥功能，相应地，抽屉设有送风口和回风口。当抽屉需要保湿时，抽屉内不再需要冷却气流，此时，现有技术通常通过关闭送风口处的送风风门阻止冷却气流继续进入抽屉内，然而却忽略了抽屉的回风口，抽屉的回风口直接暴露于冷藏室，存在冷藏室的回风通过抽屉的回风口进入抽屉内对抽屉内的温湿度产生影响的情况。This kind of refrigerator usually realizes the drying function by inputting the cooling airflow flowing through the evaporator into the drawer, and accordingly, the drawer is provided with an air supply port and an air return port. When the drawer needs moisturizing, the cooling air flow is no longer needed in the drawer. At this time, the prior art usually prevents the cooling air flow from continuing to enter the drawer by closing the air supply damper at the air supply port, but ignores the air return port of the drawer. The air outlet is directly exposed to the refrigerator, and the return air of the refrigerator enters the drawer through the return air outlet of the drawer and affects the temperature and humidity in the drawer.

In particular, the refrigerator of the present invention is also provided with an air supply damper on the air flow path between the evaporator and the air supply opening of the storage device, and a return air damper at the return air opening of the storage device. When the storage device is switched to the drying mode, the air supply damper and the return air damper can be opened in a controlled manner to allow the cooling airflow generated by the evaporator to flow into the storage device, and the original air in the storage device is returned to the storage device through the return air outlet and the compartment. The air duct returns to the evaporator, thereby displacing the air in the storage unit. When the air flow passes through the evaporator with a lower temperature, the moisture in the air flow will condense on the evaporator, so that the temperature and humidity of the formed cooling air flow are relatively low, so when the cooling air flow replaces the air in the storage device, the storage device A dry storage space with low temperature and low humidity can be formed in the storage device. When the humidity in the storage device drops to a preset humidity threshold corresponding to the drying mode, the air supply damper and the return air damper can be closed in a controlled manner. At this time, even if the return air flow of the storage compartment flows through the return air duct of the compartment, and no matter whether negative pressure or pressurization is formed in the storage device, under the obstruction of the return air door, the air flow in the return air duct of the compartment will All the airflow will not flow into the storage device to affect the humidity in the storage device. When the humidity in the storage device is higher than the preset humidity threshold corresponding to the drying mode, the air supply damper and the return air damper can be opened again, and so on, so that the storage device maintains the preset humidity threshold corresponding to the drying mode. When the storage device is switched to the moisturizing mode, the air supply damper and the return air damper are closed in a controlled manner, so as to prevent the cooling airflow and the return airflow of the compartment from flowing into the storage device. Fruits and vegetables volatilize a large amount of water, so that a high-humidity space with high humidity is formed in the storage device, which is beneficial to the preservation of fruits and vegetables. It can be seen that the present invention forms a dry and wet adjustable storage space in the storage device by setting the air supply damper and the return air damper, and controlling the opening and closing of the air supply damper and the return air damper, and the humidity of the storage space It will not be affected by the storage compartment, and the preservation quality of the items in the storage device is improved.

进一步地，本发明的冰箱还包括用于向储物装置内输送冷却气流的装置送风风道，且该装置送风风道与间室送风风道相互独立，其一端直接与蒸发器连通，而不是通过间室送风风道间接地与蒸发器连通。一方面，储物装置与储物间室的送风互不影响，当储物装置需要送风时不必考虑储物间室是否处于制冷状态、是否需要制冷以及制冷量的多少等，也即是，储物装置的送风不会对储物间室的温度产生影响；另一方面，经装置送风风道送出的全部气流均可以流向储物装置，经间室送风风道送出的全部气流均可以流向储物间室，增大了储物装置需要送风时的送风量以及储物间室需要制冷时的送风量，从而提高了储物装置在干燥模式下的湿度调节效率以及储物间室的制冷效率。Further, the refrigerator of the present invention also includes a device air supply air duct for delivering cooling airflow to the storage device, and the device air supply air duct is independent from the compartment air supply air duct, and one end thereof directly communicates with the evaporator , instead of indirectly communicating with the evaporator through the compartment air supply duct. On the one hand, the air supply between the storage device and the storage compartment does not affect each other. When the storage device needs to supply air, it is not necessary to consider whether the storage compartment is in a refrigerated state, whether it needs to be refrigerated, and the amount of cooling capacity. , the air supply from the storage device will not affect the temperature of the storage compartment; The air flow can flow to the storage compartment, which increases the air supply volume when the storage device needs air supply and the air supply volume when the storage compartment needs to be cooled, thereby improving the humidity adjustment efficiency of the storage device in the dry mode and the cooling efficiency of the storage compartment.

具体实施方式Detailed ways

本发明提供一种冰箱，图1是根据本发明一个实施例的冰箱的示意性结构图，参见图1，本发明的冰箱1包括限定有储物间室11的箱体10、以及设置于储物间室11内的储物装置40。具体地，储物间室11可以为具有冷藏储物环境的冷藏间室，也可以为变温间室或其他保鲜间室。进一步地，储物间室11的后侧可设有风道盖板30。The present invention provides a refrigerator. FIG. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present invention. Referring to FIG. The storage device 40 in the object compartment 11. Specifically, the storage compartment 11 may be a refrigerated compartment with a refrigerated storage environment, or may be a temperature-changing compartment or other fresh-keeping compartments. Further, the rear side of the storage compartment 11 may be provided with an air duct cover plate 30 .

图2是根据本发明一个实施例的冰箱的部分结构示意图，图3是根据本发明一个实施例的冰箱的部分结构的示意后视图，图4是根据本发明一个实施例的储物装置的示意性结构图。参见图2至图4，本发明的冰箱1还包括用于提供冷却气流的蒸发器20、用于将冷却气流送往储物间室11的间室送风风道12、用于供储物间室11内的回风气流返回蒸发器20的间室回风风道13。储物装置40具有用于供气流流入其内部空间的送风口41和用于供其内部空间的气流流出的回风口42，回风口42与间室回风风道13连通。需要说明的是，为了便于看清楚风道结构，图2和图3中省去了用于覆盖各风道的结构件。Fig. 2 is a schematic diagram of a partial structure of a refrigerator according to an embodiment of the present invention, Fig. 3 is a schematic rear view of a partial structure of a refrigerator according to an embodiment of the present invention, and Fig. 4 is a schematic diagram of a storage device according to an embodiment of the present invention sex structure diagram. Referring to Fig. 2 to Fig. 4, the refrigerator 1 of the present invention also includes an evaporator 20 for providing cooling airflow, a compartment air supply duct 12 for sending the cooling airflow to the storage compartment 11, and a compartment for storing goods. The return air flow in the compartment 11 returns to the compartment return air duct 13 of the evaporator 20 . The storage device 40 has an air supply port 41 for air flow into its internal space and an air return port 42 for air flow in its internal space to flow out. The air return port 42 communicates with the return air duct 13 in the compartment. It should be noted that, in order to make it easier to see the structure of the air duct, the structural members used to cover each air duct are omitted in FIG. 2 and FIG. 3 .

特别地，冰箱1还包括送风风门71和回风风门72。In particular, the refrigerator 1 further includes an air supply damper 71 and a return air damper 72 .

送风风门71设置在蒸发器20与送风口41之间的气流流动路径上，且配置成在储物装置40处于干燥模式时受控地打开或关闭以选择性地允许蒸发器20产生的冷却气流流入储物装置40内、在储物装置40处于保湿模式时受控地关闭以阻止蒸发器20产生的冷却气流流入储物装置40内。可以理解的是，干燥模式和保湿模式是储物装置40的两个不同的功能模式，当储物装置40分别处于干燥模式和保湿模式时，其内部空间对应的预设湿度范围是不同的。The air supply damper 71 is disposed on the air flow path between the evaporator 20 and the air supply port 41 and is configured to be controlled to open or close to selectively allow the cooling generated by the evaporator 20 when the storage device 40 is in the drying mode. The air flow into the storage device 40 is controlled closed to prevent the cooling air flow generated by the evaporator 20 from flowing into the storage device 40 when the storage device 40 is in the moisturizing mode. It can be understood that the drying mode and the moisturizing mode are two different functional modes of the storage device 40, and when the storage device 40 is in the drying mode and the moisturizing mode respectively, the preset humidity ranges corresponding to the internal spaces are different.

回风风门72设置在回风口42处，且配置成与送风风门71同步地打开以允许储物装置40内的回风气流经间室回风风道13流向蒸发器20、且与送风风门71同步地关闭以阻止气流流入和流出储物装置40。The return air damper 72 is arranged at the return air outlet 42, and is configured to open synchronously with the air supply damper 71 to allow the return air in the storage device 40 to flow to the evaporator 20 through the return air duct 13 of the compartment, and to communicate with the supply air. The dampers 71 are closed synchronously to prevent air flow into and out of the storage device 40 .

当储物装置40切换至干燥模式时，送风风门71和回风风门72可受控地打开以允许蒸发器20产生的冷却气流流入储物装置40内，储物装置40内原有的空气经回风口42和间室回风风道13返回蒸发器20，从而置换储物装置40内的空气。由于气流流经温度较低的蒸发器20时，气流中的水分会在蒸发器20上凝结，从而使得形成的冷却气流的温度和湿度都比较低，因此当冷却气流置换储物装置40内的空气后储物装置40内可形成低温低湿的干燥储物空间。当储物装置40内的湿度降低至干燥模式对应的预设湿度阈值时可受控地关闭送风风门71和回风风门72。此时，即便间室回风风道13内有储物间室11的回风气流流过、且无论储物装置40内是否形成负压或增压，在回风风门72的阻挡下，间室回风风道13及储物间室11内的气流都不会流入储物装置40中对储物装置40中的湿度产生影响。当储物装置40内的湿度高于干燥模式对应的预设湿度阈值时可再次打开送风风门71和回风风门72，如此反复，使得储物装置40内维持在干燥模式对应的预设湿度阈值。When the storage device 40 is switched to the drying mode, the air supply damper 71 and the return air damper 72 can be controlled to open to allow the cooling airflow generated by the evaporator 20 to flow into the storage device 40, and the original air in the storage device 40 is passed through. The return air outlet 42 and the compartment return air duct 13 return to the evaporator 20 to replace the air in the storage device 40 . When the air flow passes through the evaporator 20 with a lower temperature, the moisture in the air flow will condense on the evaporator 20, so that the temperature and humidity of the formed cooling air flow are relatively low. A low-temperature and low-humidity dry storage space can be formed in the air storage device 40 . When the humidity in the storage device 40 drops to a preset humidity threshold corresponding to the drying mode, the air supply damper 71 and the return air damper 72 can be closed in a controlled manner. At this time, even if the return air flow of the storage compartment 11 flows through the compartment return air duct 13, and no matter whether negative pressure or pressurization is formed in the storage device 40, under the blocking of the return air door 72, the The airflow in the room return air duct 13 and the storage compartment 11 will not flow into the storage device 40 to affect the humidity in the storage device 40 . When the humidity in the storage device 40 is higher than the preset humidity threshold corresponding to the drying mode, the air supply damper 71 and the return air damper 72 can be opened again, and so on, so that the storage device 40 maintains the preset humidity corresponding to the drying mode threshold.

当储物装置40切换至保湿模式时，送风风门71和回风风门72受控地关闭，以阻止冷却气流和储物间室11的回风气流流入储物装置40内，储物装置40内储存的含水量较大的果蔬等物品挥发大量的水分，使得储物装置40内形成湿度较高的高湿空间，利于果蔬等物品的保存。When the storage device 40 is switched to the moisturizing mode, the air supply damper 71 and the return air damper 72 are closed in a controlled manner, so as to prevent the cooling airflow and the return airflow of the storage compartment 11 from flowing into the storage device 40, and the storage device 40 The items such as fruits and vegetables with relatively large water content volatilize a large amount of water, so that a high-humidity space with relatively high humidity is formed in the storage device 40, which is beneficial to the preservation of items such as fruits and vegetables.

可见，本发明通过设置送风风门71和回风风门72、以及对送风风门71和回风风门72的开闭控制在储物装置40内形成了干湿可调的储物空间，且该储物空间的湿度不会受到储物间室11的影响，提高了储物装置40内物品的保存品质。It can be seen that the present invention forms a dry and wet adjustable storage space in the storage device 40 by setting the air supply damper 71 and the return air damper 72, and controlling the opening and closing of the air supply damper 71 and the return air damper 72, and the The humidity of the storage space will not be affected by the storage compartment 11 , which improves the storage quality of the items in the storage device 40 .

进一步地，储物装置40还包括允许其内部的水分向外渗透的透湿膜47，当储物装置40内的湿度过高时，过多的水分可以通过透湿膜47向外透出，避免储物装置40内因湿度过大而出现凝露现象。Further, the storage device 40 also includes a moisture-permeable film 47 that allows moisture inside to permeate outward. When the humidity in the storage device 40 is too high, excessive moisture can pass through the moisture-permeable film 47 to the outside. Avoid condensation in the storage device 40 due to excessive humidity.

发明人认识到，在本申请之前，具有干湿可调空间的储物装置的送风口直接与储物间室的送风风道连通，并且送风风门通常设置在送风口处。当储物装置需要降低湿度时，冰箱1的送风风机必须启动(无论储物间室是否需要制冷)，向间室的送风风道内输送冷却气流。储物间室的送风风道内的部分冷却气流流向储物间室、另一部分冷却气流流向储物装置，然而，冷却气流的分流不但减少了流向储物装置的冷却气流量，而且还可能导致储物间室内的温度低于其设定温度。The inventor realized that before this application, the air outlet of the storage device with adjustable dry and wet space was directly connected with the air supply duct of the storage compartment, and the air supply door was usually arranged at the air outlet. When the storage device needs to reduce the humidity, the air supply fan of the refrigerator 1 must be started (whether the storage compartment needs refrigeration), and the cooling air flow is delivered to the air supply duct of the compartment. Part of the cooling air flow in the air supply duct of the storage compartment flows to the storage compartment, and another part of the cooling air flow flows to the storage device. However, the diversion of the cooling air flow not only reduces the cooling air flow to the storage device, but also may cause The temperature in the storage compartment is lower than its set temperature.

为此，在一些实施例中，本发明的冰箱1还包括与间室送风风道12相互独立的装置送风风道14，装置送风风道14的一端直接与蒸发器20连通，另一端与储物装置40的送风口41连通，用于直接向储物装置40内输送蒸发器20产生的冷却气流。本发明的装置送风风道14与间室送风风道12相互独立，而不是通过间室送风风道12间接地与蒸发器20连通。一方面，储物装置40与储物间室11的送风互不影响，当储物装置40需要送风时不必考虑储物间室11是否处于制冷状态、是否需要制冷以及制冷量的多少等，也即是，储物装置40的送风不会对储物间室11的温度产生影响；另一方面，经装置送风风道14送出的全部气流均可以流向储物装置40，经间室送风风道11送出的全部气流均可以流向储物间室11，增大了储物装置40需要送风时的送风量以及储物间室11需要制冷时的送风量，从而提高了储物装置40在干燥模式下的湿度调节效率以及储物间室11的制冷效率。For this reason, in some embodiments, the refrigerator 1 of the present invention also includes a device air supply duct 14 that is independent of the compartment air supply duct 12, one end of the device air supply duct 14 is directly connected to the evaporator 20, and the other One end communicates with the air outlet 41 of the storage device 40 , and is used for directly delivering the cooling airflow generated by the evaporator 20 into the storage device 40 . The air supply air duct 14 of the device of the present invention is independent from the compartment air supply duct 12 , rather than indirectly communicating with the evaporator 20 through the compartment air supply duct 12 . On the one hand, the air supply of the storage device 40 and the storage compartment 11 does not affect each other. When the storage device 40 needs air supply, it is not necessary to consider whether the storage compartment 11 is in a cooling state, whether cooling is required, and the amount of cooling capacity, etc. , that is, the air supply from the storage device 40 will not affect the temperature of the storage compartment 11; All the airflow sent by the room air supply duct 11 can flow to the storage compartment 11, which increases the air supply volume when the storage device 40 needs air supply and the air supply volume when the storage compartment 11 needs cooling, thereby improving The humidity adjustment efficiency of the storage device 40 in the drying mode and the cooling efficiency of the storage compartment 11 are determined.

在一些实施例中，冰箱1还包括间室送风风门73，间室送风风门73和送风风门71可分别设置在间室送风风道12和装置送风风道14中，以分别受控地导通或阻断间室送风风道12和装置送风风道14。In some embodiments, the refrigerator 1 further includes a compartment air supply door 73, and the compartment air supply damper 73 and the air supply damper 71 can be respectively arranged in the compartment air supply duct 12 and the device air supply duct 14 to respectively The air supply duct 12 of the compartment and the air supply duct 14 of the device are switched on or off in a controlled manner.

优选地，间室送风风门73设置于间室送风风道12的邻近蒸发器20的端部，用于受控地导通和/或阻断间室送风风道12，以选择性地向储物间室11内输送冷却气流。优选地，送风风门71可设置于装置送风风道14的邻近蒸发器20的端部。由此，可以将储物间室11和储物装置40的送风完全地独立开。当储物间室11不需要制冷时，间室送风风道12内不会有任何冷却气流流过，使得送风风机驱动的全部冷却气流均流向装置送风风道14；当储物装置40不需要降湿时，装置送风风道14内不会有任何冷却气流流过，使得送风风机驱动的全部冷却气流均流向间室送风风道12，进一步提高了储物装置40在干燥模式下的湿度调节效率以及储物间室11的制冷效率。当储物装置40需要降湿、且储物间室11需要制冷时，间室送风风门73和送风风门71均打开，以使得部分冷却气流通过间室送风风道12流向储物间室11、另一部分冷却气流通过装置送风风道14流向储物装置40，同步实现储物装置40的降湿和储物间室11的制冷。Preferably, the compartment air supply air door 73 is arranged at the end of the compartment air supply duct 12 adjacent to the evaporator 20, and is used to controlly conduct and/or block the compartment air supply duct 12 to selectively The cooling air flow is sent into the storage compartment 11 in a stable manner. Preferably, the air supply door 71 may be disposed at an end of the air supply duct 14 of the device adjacent to the evaporator 20 . Thereby, the ventilation of the storage compartment 11 and the storage device 40 can be completely separated. When the storage compartment 11 does not need to be refrigerated, there will not be any cooling airflow to flow through in the compartment air supply duct 12, so that all the cooling airflow driven by the air supply fan will flow to the device air supply duct 14; 40 When dehumidification is not required, there will be no cooling air flow in the air supply duct 14 of the device, so that all the cooling air flow driven by the air supply fan will flow to the air supply duct 12 in the compartment, further improving the storage device 40. Humidity conditioning efficiency in dry mode and cooling efficiency of the storage compartment 11. When the storage device 40 needs to dehumidify and the storage compartment 11 needs to be refrigerated, both the compartment air supply damper 73 and the air supply damper 71 are opened, so that part of the cooling air flows to the storage compartment through the compartment air supply duct 12 The room 11 and another part of the cooling air flow to the storage device 40 through the air supply duct 14 of the device, so as to realize the dehumidification of the storage device 40 and the cooling of the storage compartment 11 simultaneously.

进一步地，储物间室11的后侧设有风道盖板30，蒸发器20位于风道盖板30的后侧，间室送风风道12和装置送风风道14均形成在风道盖板30的后向表面，间室回风风道13形成在风道盖板30的下部并位于蒸发器20的下方。Further, the rear side of the storage compartment 11 is provided with an air duct cover plate 30, the evaporator 20 is located on the rear side of the air duct cover plate 30, and the compartment air supply duct 12 and the device air supply duct 14 are both formed in the wind. On the rear surface of the duct cover plate 30 , the compartment return air duct 13 is formed on the lower part of the duct cover plate 30 and located below the evaporator 20 .

具体地，参见图6所示的根据本发明一个实施例的风道盖板的示意性正视图，风道盖板30上开设有与装置送风风道14的另一端端部连通的装置出风端口31，在储物装置40处于完全容置在储物间室11内的关闭状态时，装置出风端口31与形成在储物装置40后部的送风口41密封连通，从而实现了储物装置40与装置送风风道14之间的流体连通。Specifically, referring to the schematic front view of the air duct cover plate according to one embodiment of the present invention shown in FIG. The air port 31, when the storage device 40 is in the closed state completely accommodated in the storage compartment 11, the device air outlet port 31 is in sealing communication with the air supply port 41 formed at the rear of the storage device 40, thereby realizing storage Fluid communication between the object device 40 and the device air supply duct 14.

图5是根据本发明一个实施例的储物装置的示意性分解图。在一些实施例中，储物装置40可包括密封上盖43和抽屉44。密封上盖43固定设置在储物间室11中。抽屉44具有顶部开口，且配置成可推拉地设置于密封上盖43的下方，以在其处于完全推入储物间室11内的关闭状态时使得密封上盖43覆盖抽屉44的顶部开口从而在密封上盖43和抽屉44之间限定出封闭空间、在其处于从储物间室11中拉出的打开状态时使得抽屉44与密封上盖43分离以暴露出抽屉44的顶部开口。Fig. 5 is a schematic exploded view of a storage device according to an embodiment of the present invention. In some embodiments, the storage device 40 may include a sealed lid 43 and a drawer 44 . The sealing upper cover 43 is fixedly arranged in the storage compartment 11 . The drawer 44 has a top opening, and is configured to be pushed and pulled under the sealing upper cover 43, so that when it is in a closed state fully pushed into the storage compartment 11, the sealing upper cover 43 covers the top opening of the drawer 44 so that A closed space is defined between the sealing upper cover 43 and the drawer 44 , and the drawer 44 is separated from the sealing upper cover 43 to expose the top opening of the drawer 44 when it is in an open state pulled out from the storage compartment 11 .

相比于现有技术中具有密封桶体和抽屉的储物装置来说，本发明的储物装置40通过密封上盖43与抽屉44配合形成封闭空间，一方面，可使得储物装置40更加小型化，占用空间更小，且成本更低，另一方面，各风口可直接开设在抽屉44上，用于调节储物装置40内湿度的气流可直接流入抽屉44内，气流阻力较小，湿度调节的速度更快。Compared with storage devices with sealed barrels and drawers in the prior art, the storage device 40 of the present invention forms a closed space through the cooperation of the sealed upper cover 43 and the drawer 44. On the one hand, the storage device 40 can be made more Miniaturization, smaller space occupation, and lower cost. On the other hand, each air outlet can be directly opened on the drawer 44, and the airflow used to adjust the humidity in the storage device 40 can directly flow into the drawer 44, and the airflow resistance is small. Humidity regulation is faster.

具体地，在储物装置40处于关闭状态时，风道盖板30上的装置出风端口31与储物装置40的送风口41密封连通。为了进一步提高密封性能，装置出风端口31与送风口41的周向边缘之间还设有密封泡棉，密封泡棉可以固定在装置出风端口31的周向边缘。Specifically, when the storage device 40 is in a closed state, the device air outlet port 31 on the air duct cover plate 30 is in sealing communication with the air supply port 41 of the storage device 40 . In order to further improve the sealing performance, sealing foam is provided between the peripheral edge of the air outlet port 31 of the device and the air supply port 41 , and the sealing foam can be fixed on the peripheral edge of the air outlet port 31 of the device.

进一步地，发明人认识到，为了便于与风道盖板30上的装置送风风道14连通，送风口41优选开设在储物装置40的后侧，并且高度越高越好。为此，送风口41可以开设在抽屉44后端板的最上部。然而，发明人认识到，即使将送风口41设置在抽屉44的最上部，其高度仍然不是最高的，且也避免不了被抽屉44内存放的物品封堵的风险。Further, the inventor realized that, in order to communicate with the device air supply duct 14 on the air duct cover plate 30, the air supply opening 41 is preferably opened at the rear side of the storage device 40, and the higher the height, the better. For this reason, air supply port 41 can be offered at the top of drawer 44 rear end plates. However, the inventor realized that even if the air outlet 41 is arranged at the uppermost part of the drawer 44 , its height is still not the highest, and the risk of being blocked by the items stored in the drawer 44 cannot be avoided.

为此，在一些实施例中，密封上盖43包括水平延伸的盖板431和由盖板431的后侧边缘向下延伸的后侧边缘部432，后侧边缘部432开设有开口向下的第一槽口433，抽屉44的后端板441的上部开设有开口向上的第二槽口442。当抽屉44处于关闭状态时，第一槽口433和第二槽口442对接并形成了封闭的送风口41。也就是说，本发明的送风口41并不完全地开设在抽屉44上，而是由分别形成在密封上盖43和抽屉44上的两个槽口拼接而成，突破了抽屉44的高度限制，使得送风口41的高度尽可能地达到最高，且送风口41最高点的高度高于抽屉44的高度，因此，送风口41不存在被抽屉44内存放的物品堵死的风险。To this end, in some embodiments, the sealing upper cover 43 includes a horizontally extending cover plate 431 and a rear side edge portion 432 extending downward from the rear side edge of the cover plate 431, and the rear side edge portion 432 is provided with a downward opening The first notch 433 and the upper part of the rear end plate 441 of the drawer 44 define a second notch 442 opening upward. When the drawer 44 is in the closed state, the first notch 433 and the second notch 442 butt to form a closed air outlet 41 . That is to say, the air outlet 41 of the present invention is not completely opened on the drawer 44, but is spliced by two notches respectively formed on the sealing upper cover 43 and the drawer 44, breaking through the height limit of the drawer 44 , so that the height of the air supply port 41 reaches the highest as possible, and the height of the highest point of the air supply port 41 is higher than the height of the drawer 44, therefore, the air supply port 41 does not have the risk of being blocked by the items stored in the drawer 44.

在一些实施例中，回风口42开设在抽屉44的后端板441的底部，延长了由送风口41流入储物装置40的冷却气流的流动路径，使得储物装置40的湿度更加均衡。In some embodiments, the air return port 42 is opened at the bottom of the rear end plate 441 of the drawer 44 , which prolongs the flow path of the cooling air flowing into the storage device 40 from the air supply port 41 , so that the humidity of the storage device 40 is more balanced.

进一步地，回风风门72设置在回风口42的外侧，以受控地在回风口42的外侧覆盖回风口42。由此，可以充分地利用储物装置40后方的空间布置回风风门72，不会占用储物装置40内部的空间，且回风风门72的打开和关闭动作不会受到储物装置40内存放物品的阻碍和影响，也不会与储物间室11内的其他结构产生干涉。Further, the return air damper 72 is arranged outside the return air opening 42 to cover the return air opening 42 on the outside of the return air opening 42 in a controlled manner. Thus, the space behind the storage device 40 can be fully utilized to arrange the air return damper 72 without occupying the space inside the storage device 40, and the opening and closing of the return air damper 72 will not be affected by the storage device 40. The hindrance and impact of the articles will not interfere with other structures in the storage compartment 11 .

具体地，储物装置40的送风口41的周向边缘可向后凸出延伸，以在储物装置40完全处于储物间室11内时使得送风口41与风道盖板30上的装置出风端口31接触并密封地连通，同时，可以在储物装置40的回风口42与风道盖板30之间形成一定的间隙，便于回风风门72执行打开或关闭动作，从而有效地避免了与风道盖板30产生碰撞或结构干涉。Specifically, the peripheral edge of the air outlet 41 of the storage device 40 can protrude backwards, so that when the storage device 40 is completely in the storage compartment 11, the air outlet 41 and the device on the air duct cover 30 The air outlet port 31 is in contact with and communicated in a sealed manner. At the same time, a certain gap can be formed between the air return port 42 of the storage device 40 and the air duct cover plate 30, so that the return air door 72 can be opened or closed, thereby effectively avoiding To avoid collision or structural interference with the air duct cover plate 30.

可以理解的是，送风风门71和回风风门72的开闭状态主要是根据储物装置40内的湿度来控制的。因此，需要对储物装置40的湿度进行准确地检测。通常比较常见的是采用湿度传感器直接获取储物装置40内的湿度，然而，发明人认识到，湿度传感器的成本较高，难以在实际的冰箱产品上得以实现。并且，发明人还认识到，影响物品保存品质的是储物装置40内的相对湿度，而不是绝对湿度，储物装置40内的相对湿度还可以通过储物装置 40内的温度获得。It can be understood that the opening and closing states of the air supply damper 71 and the return air damper 72 are mainly controlled according to the humidity inside the storage device 40 . Therefore, it is necessary to accurately detect the humidity of the storage device 40 . It is common to use a humidity sensor to directly acquire the humidity in the storage device 40 . However, the inventors have realized that the humidity sensor is expensive and difficult to implement in an actual refrigerator product. Moreover, the inventor also realized that it is the relative humidity in the storage device 40 rather than the absolute humidity that affects the storage quality of the articles, and the relative humidity in the storage device 40 can also be obtained by the temperature in the storage device 40 .

为此，在一些实施例中，本发明的冰箱1还包括感温装置80，用于检测储物装置40内的温度，以便于根据储物装置40内的温度获得储物装置40内的湿度。在储物装置40处于干燥模式时，送风风门71配置成在储物装置40内的湿度高于干燥模式对应的预设湿度阈值时受控地打开以允许蒸发器20产生的冷却气流流入储物装置40内、在储物装置40内的湿度等于或低于干燥模式对应的预设湿度阈值时受控地关闭。相应地，回风风门72与送风风门71同步地打开或关闭。由于感温装置80价格低廉，因此不但可以满足对储物装置40内的湿度进行间接检测的目的，而且还可以降低冰箱1的成本，更加实用。For this reason, in some embodiments, the refrigerator 1 of the present invention further includes a temperature sensing device 80 for detecting the temperature in the storage device 40 so as to obtain the humidity in the storage device 40 according to the temperature in the storage device 40 . When the storage device 40 is in the drying mode, the air supply damper 71 is configured to be controlled to open when the humidity in the storage device 40 is higher than the preset humidity threshold corresponding to the drying mode to allow the cooling airflow generated by the evaporator 20 to flow into the storage device. In the storage device 40, when the humidity in the storage device 40 is equal to or lower than the preset humidity threshold corresponding to the drying mode, it is controlled to close. Correspondingly, the air return damper 72 is opened or closed synchronously with the air supply damper 71 . Since the temperature sensing device 80 is cheap, it not only meets the purpose of indirect detection of the humidity in the storage device 40, but also reduces the cost of the refrigerator 1 and is more practical.

具体地，感温装置80可以为感温头。Specifically, the temperature sensing device 80 may be a temperature sensing head.

在一些实施例中，感温装置80与送风口41处于储物装置40的同一壁面，并分别邻近该壁面的两个相对的端部，即感温装置80与送风口41间隔一定的距离，而不是邻近设置。进一步地，感温装置80与送风口41所处的高度相同。由此，可以使得感温装置80所处的位置为储物装置40内气流流速最慢的位置之一，也即是湿度调节速率相对滞后的位置之一。当通过向储物装置40内输入冷却气流的方式降低其湿度时，感温装置80检测到的温度对应的湿度值达到干燥模式对应的预设湿度阈值时，储物装置40内的其他区域也已经达到该预设湿度阈值或比该预设湿度阈值更低，此时关闭回风风门72与送风风门71可以确保储物装置40内的湿度完全符合要求。In some embodiments, the temperature sensing device 80 and the air supply port 41 are located on the same wall of the storage device 40, and are respectively adjacent to two opposite ends of the wall, that is, the temperature sensing device 80 and the air supply port 41 are separated by a certain distance, rather than proximity settings. Further, the temperature sensing device 80 is at the same height as the air outlet 41 . Thus, the position of the temperature sensing device 80 can be one of the positions with the slowest airflow velocity in the storage device 40 , that is, one of the positions where the humidity adjustment rate is relatively lagging. When the humidity of the storage device 40 is reduced by inputting cooling airflow into the storage device 40, and the humidity value corresponding to the temperature detected by the temperature sensing device 80 reaches the preset humidity threshold value corresponding to the drying mode, other areas in the storage device 40 will also When the preset humidity threshold has been reached or lower than the preset humidity threshold, closing the return air damper 72 and the air supply damper 71 can ensure that the humidity in the storage device 40 fully meets the requirements.

进一步地，为了避免感温装置80受到储物装置40内存放物品的影响，感温装置80并不固定地设置储物装置40内，而是固定在风道盖板30上。相应地，储物装置40的后侧设有用于将感温装置80暴露于储物装置40内的温度获取通孔45。温度获取通孔45的位置与感温装置80的位置相对应，以在储物装置40完全地处于储物间室11时使得感温装置80经温度获取通孔45暴露于储物装置40内。Further, in order to prevent the temperature sensing device 80 from being affected by the items stored in the storage device 40 , the temperature sensing device 80 is not fixedly arranged in the storage device 40 , but is fixed on the air duct cover plate 30 . Correspondingly, the rear side of the storage device 40 is provided with a temperature acquisition through hole 45 for exposing the temperature sensing device 80 to the storage device 40 . The position of the temperature acquisition through hole 45 corresponds to the position of the temperature sensing device 80, so that the temperature sensing device 80 is exposed to the storage device 40 through the temperature acquisition through hole 45 when the storage device 40 is completely in the storage compartment 11 .

图7是图2中部分A的示意性放大图，图8是图2所示结构的示意性分解图。在一些实施例中，储物装置40还具有增湿回风口46。在这些实施例中，冰箱1还包括增湿循环风路51、蓄水槽52、增湿模块53和增湿风机54。增湿循环风路51位于储物间室11的外部，且其两端分别与送风口41和增湿回风口46连通。蓄水槽52位于蒸发器20的下方，用于蓄存蒸发器20产生的部分冷凝水。增湿模块53的第一端部531位于蓄水槽52中以吸附蓄水槽52内的冷凝水，增湿模块53的第二端部延伸至增湿循环风路51中。增湿风机54设置于增湿循环风路51中，且配置成在储物装置40需要加湿时受控地启动，以促使经增湿回风口46流入增湿循环风路51中的气流流经增湿模块53后通过送风口41流入储物装置40内。FIG. 7 is a schematic enlarged view of part A in FIG. 2 , and FIG. 8 is a schematic exploded view of the structure shown in FIG. 2 . In some embodiments, the storage device 40 also has a humidification return air outlet 46 . In these embodiments, the refrigerator 1 further includes a humidification circulation air path 51 , a water storage tank 52 , a humidification module 53 and a humidification fan 54 . The humidification circulation air passage 51 is located outside the storage compartment 11 , and its two ends communicate with the air supply port 41 and the humidification return air port 46 respectively. The water storage tank 52 is located below the evaporator 20 and is used to store part of the condensed water produced by the evaporator 20. The first end portion 531 of the humidification module 53 is located in the water storage tank 52 to absorb the condensed water in the water storage tank 52 , and the second end portion of the humidification module 53 extends into the humidification circulation air path 51 . The humidification blower 54 is arranged in the humidification circulation air passage 51, and is configured to be activated in a controlled manner when the storage device 40 needs to be humidified, so as to promote the air flow flowing into the humidification circulation air passage 51 through the humidification return air outlet 46. The humidification module 53 then flows into the storage device 40 through the air outlet 41 .

由于增湿模块具有吸附水的功能，其第一端部531吸附的冷凝水在毛细力作用下可遍布于增湿模块53的各个区域，即增湿模块53的第二端部532中也含有水。当储物装置40需要加湿时，设置在增湿循环风路51中的增湿风机54启动，促使气流在储物装置40和增湿循环风路51之间循环流动。当气流流经位于增湿循环风路51中的增湿模块53的第二端部532时带走第二端部532含有的部分水分，湿度增加，由此实现了快速对储物装置40进行增湿的目的。由于蓄水槽52、增湿循环风路51、增湿模块53以及增湿风机54等增湿相关的结构均处在储物间室11之外，仅有增湿循环风路51的两端与储物装置40的送风口41和增湿回风口46连通，不但达到了对储物装置40快速增湿的目的，而且这些增湿结构不会对储物间室11产生任何影响。Since the humidification module has the function of absorbing water, the condensed water absorbed by the first end 531 can be spread over various areas of the humidification module 53 under the action of capillary force, that is, the second end 532 of the humidification module 53 also contains water. When the storage device 40 needs to be humidified, the humidification blower 54 arranged in the humidification circulation air path 51 is activated, and the air flow is circulated between the storage device 40 and the humidification circulation air path 51 . When the air flow passes through the second end 532 of the humidification module 53 located in the humidification circulation air path 51, part of the moisture contained in the second end 532 will be taken away, and the humidity will increase, thus realizing the rapid cleaning of the storage device 40. Humidification purpose. Since the water storage tank 52, the humidification circulation air passage 51, the humidification module 53 and the humidification fan 54 and other humidification-related structures are all outside the storage compartment 11, only the two ends of the humidification circulation air passage 51 are connected to each other. The air supply port 41 of the storage device 40 communicates with the humidification return air port 46 , which not only achieves the purpose of quickly humidifying the storage device 40 , but also these humidification structures will not have any impact on the storage compartment 11 .

进一步地，增湿循环风路51可形成在风道盖板30中。相应地，蓄水槽52、增湿模块53和增湿风机54均位于风道盖板30上，简化了储物间室11内的结构，避免对储物间室11内的空间大小产生影响。Further, the humidification circulating air passage 51 may be formed in the air duct cover plate 30 . Correspondingly, the water storage tank 52 , humidification module 53 and humidification fan 54 are all located on the air duct cover plate 30 , which simplifies the structure in the storage compartment 11 and avoids affecting the size of the storage compartment 11 .

具体地，送风口41和增湿回风口46均开设在储物装置40的后侧，以便于与形成在风道盖板30上的增湿循环风路51连通。Specifically, both the air supply port 41 and the humidification air return port 46 are opened on the rear side of the storage device 40 so as to communicate with the humidification circulation air passage 51 formed on the air duct cover plate 30 .

进一步地，参见图6，风道盖板30的前侧还形成有与增湿循环风路51的两端分别连通的增湿送风端口33和增湿回风端口34，在储物装置40完全处于储物间室11内时，增湿送风端口33和增湿回风端口34分别与储物装置40的送风口41和增湿回风口46密封连通。为了进一步提高密封性能，送风口41与增湿送风端口33的周向边缘之间、以及增湿回风口46与增湿回风端口34的周向边缘之间还分别设有密封泡棉，密封泡棉可以固定在增湿送风端口33和增湿回风端口34的周向边缘。Further, referring to FIG. 6 , the front side of the air duct cover plate 30 is also formed with a humidification air supply port 33 and a humidification return air port 34 respectively communicating with the two ends of the humidification circulating air passage 51 . When completely inside the storage compartment 11 , the humidification air supply port 33 and the humidification return air port 34 are respectively in sealing communication with the air supply port 41 and the humidification return air port 46 of the storage device 40 . In order to further improve the sealing performance, sealing foam is also provided between the air supply port 41 and the circumferential edge of the humidification air supply port 33, and between the humidification return air opening 46 and the circumferential edge of the humidification return air port 34, The sealing foam can be fixed on the circumferential edges of the humidification air supply port 33 and the humidification return air port 34 .

在一些实施例中，冰箱1还包括增湿控制风门55，增湿控制风门55设置于增湿循环风路51中，且配置成受控地导通和/或阻断增湿循环风路51。具体地，增湿控制风门55可仅在储物装置40需要增湿时打开以导通增湿循环风路51。在储物装置40不需要增湿时，可通过关闭增湿控制风门55阻断增湿循环风路51，从而避免增湿模块53对储物装置40内的湿度产生影响。In some embodiments, the refrigerator 1 further includes a humidification control damper 55, which is disposed in the humidification circulation air passage 51 and is configured to conduct and/or block the humidification circulation air passage 51 in a controlled manner. . Specifically, the humidification control damper 55 can be opened only when the storage device 40 needs to be humidified so as to conduct the humidification circulation air path 51. When the storage device 40 does not need humidification, the humidification circulation air path 51 can be blocked by closing the humidification control damper 55 , so as to prevent the humidification module 53 from affecting the humidity in the storage device 40 .

由于蓄水槽52设置在蒸发器20的下方，蒸发器20的温度非常低，可能导致蓄水槽52内蓄存的冷凝水凝结，从而影响增湿模块53的吸水效果。Since the water storage tank 52 is disposed below the evaporator 20 , the temperature of the evaporator 20 is very low, which may cause the condensed water stored in the water storage tank 52 to condense, thereby affecting the water absorption effect of the humidification module 53 .

为此，在一些实施例中，本发明的冰箱1还包括加热装置56，加热装置56配置成在储物装置40需要加湿时受控地启动，以为蓄水槽52提供热量促使蓄水槽52内的冰霜融化。也就是说，每次储物装置40需要加湿时，加热装置56都会启动对蓄水槽52进行加热，确保了储物装置40需要加湿时蓄水槽52内具有液态水，从而确保了增湿模块53的吸水效果，进而保证了储物装置40较好的增湿效果。For this reason, in some embodiments, the refrigerator 1 of the present invention further includes a heating device 56 configured to be activated in a controlled manner when the storage device 40 needs to be humidified, so as to provide heat for the water storage tank 52 to promote the humidity in the water storage tank 52. Frost melted. That is to say, each time the storage device 40 needs to be humidified, the heating device 56 will start to heat the water storage tank 52, ensuring that there is liquid water in the water storage tank 52 when the storage device 40 needs to be humidified, thereby ensuring that the humidification module 53 The water absorption effect is better, thereby ensuring the better humidification effect of the storage device 40.

进一步地，加热装置56为贴设于蓄水槽52的底壁外表面的加热丝或加热片。也就是说，加热装置56不会与蓄水槽52内的冷凝水接触，避免冷凝水对加热装置56的性能产生影响。Further, the heating device 56 is a heating wire or a heating sheet attached to the outer surface of the bottom wall of the water storage tank 52 . That is to say, the heating device 56 will not contact the condensed water in the water storage tank 52 , so as to prevent the condensed water from affecting the performance of the heating device 56 .

在一些实施例中，冰箱1还包括接水盘81，接水盘81位于蒸发器20的下方，用于收集蒸发器20产生的冷凝水。具体地，接水盘81的底部可设有排水口，以及时地将蒸发器20产生的冷凝水排出。In some embodiments, the refrigerator 1 further includes a water receiving tray 81 located below the evaporator 20 for collecting condensed water generated by the evaporator 20 . Specifically, a drain port may be provided at the bottom of the water receiving tray 81 to discharge the condensed water generated by the evaporator 20 in a timely manner.

申请人认识到，储物装置40并不需要长时间频繁地增湿，因此，储物装置40增湿所需要的水量较少。若如现有技术那样，将蒸发器20产生的所有冷凝水都吸附到增湿模块53中很容易导致冷凝水过剩、积水、结冰等问题，需要考虑增湿模块53的溢水、排水等问题，将结构复杂化。Applicants have recognized that the storage unit 40 does not need to be humidified frequently over an extended period of time, and therefore, a lesser amount of water is required to humidify the storage unit 40 . If, as in the prior art, all the condensed water generated by the evaporator 20 is absorbed into the humidification module 53, it will easily lead to problems such as excess condensed water, water accumulation, freezing, etc., and the overflow and drainage of the humidification module 53 must be considered. problem, complicating the structure.

为此，本申请进一步将蓄水槽52设置在接水盘81的横向侧部，蓄水槽52的顶部开口与接水盘81连通。由此，蓄水槽52仅收集蒸发器20侧部滴落的冷凝水即可满足增湿需求，蒸发器20其他大部分区域滴落的冷凝水仍然通过接水盘81收集并排出。并且，蓄水槽52内的冷凝水量过多时还可以直接溢出到接水盘81，不需要增加辅助的溢水通道，充分地利用了冰箱现有的结构，避免附加结构过多导致冰箱结构复杂、成本较高等。For this reason, the present application further arranges the water storage tank 52 on the lateral side of the water receiving tray 81 , and the top opening of the water storage tank 52 communicates with the water receiving tray 81 . Therefore, the water storage tank 52 only collects the condensed water dripping from the side of the evaporator 20 to meet the humidification requirement, and the condensed water dripping from most other areas of the evaporator 20 is still collected and discharged through the water receiving tray 81 . Moreover, when the amount of condensed water in the water storage tank 52 is too much, it can also directly overflow to the water receiving tray 81 without adding an auxiliary overflow channel, and fully utilizes the existing structure of the refrigerator to avoid the complicated structure and cost of the refrigerator caused by too many additional structures. Higher.

进一步地，蓄水槽52为由接水盘81的横向侧边缘向下凹陷形成的凹槽。也就是说，蓄水槽52可以在风道盖板30成型时通过吸附、注塑等工艺直接形成，省去了蓄水槽52与风道盖板30之间的装配结构。由此，蓄水槽52的设置没有增加冰箱1的任何结构负担和装配负担，最大化地减小了对冰箱原有结构的影响和改动。Further, the water storage tank 52 is a groove formed by the lateral edge of the water receiving tray 81 being depressed downward. That is to say, the water storage tank 52 can be directly formed by adsorption, injection molding and other processes when the air duct cover plate 30 is formed, omitting the assembly structure between the water storage tank 52 and the air duct cover plate 30 . Therefore, the setting of the water storage tank 52 does not increase any structural burden and assembly burden of the refrigerator 1, and minimizes the influence and modification on the original structure of the refrigerator.

在一些实施例中，增湿模块53的第二端部532覆盖增湿循环风路51在第二端部532处的过流面，以使得增湿循环风路51内的流经该过流面的全部气流均流经增湿模块53的第二端部532，从而使得该全部气流的湿度整体增加，相比于现有技术中仅有部分气流与增湿模块接触的方案来说，本实施例的方案提高了对储物装置40内的空间进行加湿的效率。In some embodiments, the second end 532 of the humidification module 53 covers the flow surface of the humidification circulation air passage 51 at the second end 532, so that the flow in the humidification circulation air passage 51 passes through the flow passage. All the airflow on the surface flows through the second end 532 of the humidification module 53, so that the humidity of the entire airflow increases as a whole. Compared with the solution in the prior art where only part of the airflow is in contact with the humidification module, this The solution of the embodiment improves the efficiency of humidifying the space in the storage device 40 .

进一步地，为了减弱增湿模块53对气流的阻碍作用，增湿模块53可以为薄片状构件。Further, in order to reduce the hindering effect of the humidification module 53 on the airflow, the humidification module 53 may be a sheet-shaped member.

具体地，增湿模块53可以为无纺布、海绵或其他具有吸水性能的吸水材料。Specifically, the humidification module 53 may be non-woven fabric, sponge or other water-absorbing materials with water-absorbing properties.

在一些实施例中，储物装置40的数量可以为一个、两个或两个以上，当储物装置40的数量为两个时，两个储物装置40可沿横向并排设置在储物间室11的底部。相应地，装置送风风道14、送风风门71、回风风门72等相关结构的数量与储物装置40的数量保持一致。In some embodiments, the number of storage devices 40 can be one, two or more than two, and when the number of storage devices 40 is two, the two storage devices 40 can be arranged side by side in the lateral direction between the storage bottom of chamber 11. Correspondingly, the number of related structures such as the air supply duct 14 , the air supply damper 71 , and the return air damper 72 of the device is consistent with the number of storage devices 40 .
