现有的冰箱,例如风冷冰箱,通常利用送风风道向储物空间提供换热气流,从而调节储物空间的温度。然而,发明人认识到,换热气流往往不能同时调节储物空间的温度和湿度,当储物空间的湿度过大时,无法快速地除湿,因此,有必要改进冰箱的结构。Existing refrigerators, such as air-cooled refrigerators, usually use air supply ducts to provide heat exchange airflow to the storage space, thereby adjusting the temperature of the storage space. However, the inventors realized that the heat exchange airflow often cannot regulate the temperature and humidity of the storage space at the same time, and when the humidity of the storage space is too high, it cannot dehumidify quickly. Therefore, it is necessary to improve the structure of the refrigerator.

本发明的冰箱,由于箱体内设置有冷凝除湿装置,该冷凝除湿装置可在储物空间需要除湿的情况下受控地启动,以使储物空间内的水蒸气在冷凝部表面冷凝,因此,冰箱能够快速降低储物空间的湿度,这有利于提升储物空间的保鲜效果。In the refrigerator of the present invention, since the cabinet is provided with a condensation dehumidification device, the condensation dehumidification device can be activated in a controlled manner when the storage space needs to be dehumidified, so that the water vapor in the storage space condenses on the surface of the condensation part. Therefore, The refrigerator can quickly reduce the humidity of the storage space, which is beneficial to improve the freshness preservation effect of the storage space.
进一步地,本发明的冰箱,由于还设置有加热装置,该加热装置可在冷凝除湿装置启动时对流经冷凝部之后的空气进行加热,这可使因流经冷凝部而降温的空气得到热量并升温,因此,冰箱在降低储物空间湿度的同时可以避免对储物空间的温度产生影响。Furthermore, since the refrigerator of the present invention is also provided with a heating device, the heating device can heat the air flowing through the condensing part when the condensing and dehumidifying device is started, which can make the air cooled by flowing through the condensing part obtain heat and Therefore, the refrigerator can avoid affecting the temperature of the storage space while reducing the humidity of the storage space.
更进一步地,本发明的冰箱,由于冷凝部的表面形成倾斜的冷凝面,该冷凝面自冷凝部的横向两端向中部倾斜向下延伸,使得冷凝部的中部形成供冷凝水汇集的汇流槽,导流装置可将汇流槽内汇集的冷凝水及时地引出储物空间,因此,有利于减少或避免储物空间内产生的冷凝水因滞留而再次蒸发。Furthermore, in the refrigerator of the present invention, since the surface of the condensing part forms an inclined condensing surface, the condensing surface extends obliquely downward from both lateral ends of the condensing part to the middle part, so that the central part of the condensing part forms a confluence tank for condensed water to collect.

图1是根据本发明一个实施例的冰箱10的示意性结构图。冰箱10一般性地可包括箱体200、冷凝除湿装置300和加热装置400。FIG. 1 is a schematic structural diagram of a refrigerator 10 according to an embodiment of the present invention. The refrigerator 10 may generally include a box body 200 , a condensation dehumidification device 300 and a heating device 400 .
其中,箱体200的内部形成有储物空间222。储物空间222可以指用于对食材或其他物品进行低温保存的空间,例如冷藏空间,或者可以指用于对待熟成物(比如肉类)进行熟成的空间,例如熟成空间。Wherein, a storage space 222 is formed inside the box body 200 . The storage space 222 may refer to a space for low-temperature preservation of ingredients or other items, such as a refrigerated space, or may refer to a space for ripening food to be cooked (such as meat), such as a ripening space.
箱体200的内部可以形成有多个储物间室210,每个储物间室210形成一个储物空间222,上述冷藏空间或者熟成空间可以限定于任一储物间室210内,例如,储物间室210可以直接作为冷藏空间或者熟成空间。在一些可选的实施例中,储物间室210内可以设置有储物容器,储物容器的内部可以作为冷藏空间或者熟成空间。A plurality of storage compartments 210 may be formed inside the box body 200, and each storage compartment 210 forms a storage space 222, and the above-mentioned refrigerated space or ripening space may be limited in any storage compartment 210, for example, The storage compartment 210 can be directly used as a refrigerated space or an aging space. In some optional embodiments, a storage container may be provided in the storage compartment 210, and the inside of the storage container may be used as a refrigerated space or an aging space.
图2是根据本发明一个实施例的冰箱10的内部结构的主视图,图中示出了储物空间222及其周围部件,为便于示例,该图为透视图。Fig. 2 is a front view of the internal structure of the refrigerator 10 according to an embodiment of the present invention, in which a storage space 222 and its surrounding components are shown, and for convenience of illustration, the figure is a perspective view.
冷凝除湿装置300具有冷凝部320,设置于储物空间222内,且冷凝除湿装置300配置成受控地启动,以使冷凝部320周围空气中的水蒸气在冷凝部320表面冷凝,从而降低储物空间222的湿度。例如,在冷凝除湿装置300受控启动之后,冷凝部320的温度会低于储物空间222内的温度,从而促使周围空气中的水蒸气在冷凝部320表面冷凝。The condensing dehumidifier 300 has a condensing part 320, which is arranged in the storage space 222, and the condensing dehumidifying device 300 is configured to be activated in a controlled manner, so that the water vapor in the air around the condensing part 320 condenses on the surface of the condensing part 320, thereby reducing the storage capacity. The humidity of the object space 222. For example, after the condensing and dehumidifying device 300 is activated under control, the temperature of the condensing part 320 will be lower than the temperature in the storage space 222 , so that the water vapor in the surrounding air will be condensed on the surface of the condensing part 320 .
加热装置400与冷凝部320对应设置,配置成在冷凝除湿装置300启动时对流经冷凝部320之后的空气进行加热。本实施例中,加热装置400可以设置在储物空间222的内部或者外部,只要保证流经冷凝部320之后的空气可以流经加热装置400即可。例如,加热装置400与冷凝部320对应设置可以指,加热装置400邻近于冷凝部320设置,且相对于流经冷凝部320的气流路径而言,加热装置400设置于冷凝部320的下游。The heating device 400 is disposed corresponding to the condensing part 320 , and is configured to heat the air passing through the condensing part 320 when the condensing and dehumidifying device 300 is started. In this embodiment, the heating device 400 can be arranged inside or outside the storage space 222 , as long as the air passing through the condensation part 320 can flow through the heating device 400 . For example, the corresponding arrangement of the heating device 400 and the condensing part 320 may mean that the heating device 400 is arranged adjacent to the condensing part 320 , and relative to the airflow path flowing through the condensing part 320 , the heating device 400 is arranged downstream of the condensing part 320 .
由于箱体200内设置有冷凝除湿装置300,该冷凝除湿装置300可在储物空间222需要除湿的情况下受控地启动,以使储物空间222内的水蒸气在 冷凝部320表面冷凝,因此,本实施例的冰箱10能够快速降低储物空间222的湿度,这有利于提升储物空间222的保鲜效果。Since the condensation dehumidification device 300 is provided in the box body 200, the condensation dehumidification device 300 can be activated in a controlled manner when the storage space 222 needs to be dehumidified, so that the water vapor in the storage space 222 can condense on the surface of the condensation part 320, Therefore, the refrigerator 10 of this embodiment can quickly reduce the humidity of the storage space 222 , which is beneficial to improve the freshness preservation effect of the storage space 222 .
发明人认识到,由于冷凝部320的表面温度较低,当储物空间222内的空气流经冷凝部320时,伴随着水蒸气的冷凝,空气的温度会有所降低,也就是说,在利用冷凝除湿装置300降低储物空间222内部湿度的同时,会对储物空间222的温度产生影响。The inventors realized that since the surface temperature of the condensing part 320 is relatively low, when the air in the storage space 222 flows through the condensing part 320, the temperature of the air will decrease along with the condensation of water vapor. While using the condensation dehumidifier 300 to reduce the humidity inside the storage space 222 , it will also affect the temperature of the storage space 222 .
通过设置加热装置400,利用该加热装置400在冷凝除湿装置300启动时对流经冷凝部320之后的空气进行加热,这可使因流经冷凝部320而降温的空气得到热量并升温,因此,本实施例的冰箱10在降低储物空间222湿度的同时可以避免对储物空间222的温度产生影响。By setting the heating device 400, the heating device 400 is used to heat the air flowing through the condensing part 320 when the condensing and dehumidifying device 300 is started, which can make the air cooled by flowing through the condensing part 320 obtain heat and heat up. Therefore, this The refrigerator 10 of the embodiment can reduce the humidity of the storage space 222 while avoiding the impact on the temperature of the storage space 222 .
本实施例的方案,尤其适用于储物空间222为熟成空间的情况。不同种类食材的熟成往往需要在特定的气流流速下进行,储物空间222内的空气需要形成具有一定气流流速的内循环气流。基于本实施例的方案,冰箱10可以为食材的熟成提供适宜的熟成气氛,有利于形成干燥、恒温的内循环气流。The solution of this embodiment is especially suitable for the case where the storage space 222 is an aging space. The aging of different types of food materials often needs to be carried out under a specific airflow velocity, and the air in the storage space 222 needs to form an internal circulation airflow with a certain airflow velocity. Based on the solution of this embodiment, the refrigerator 10 can provide a suitable ripening atmosphere for the ripening of the ingredients, which is conducive to the formation of a dry and constant temperature internal circulation airflow.
储物空间222内可以设置有湿度传感器800,用于检测储物空间222的湿度,冰箱10可根据湿度传感器800的检测值来确定是否启动冷凝除湿装置300。例如,当湿度传感器800的检测值超出预设的湿度阈值时,可以确定启动冷凝除湿装置300,以保证储物空间222的湿度处于湿度阈值以下。A humidity sensor 800 may be provided in the storage space 222 for detecting the humidity of the storage space 222 , and the refrigerator 10 may determine whether to activate the condensation dehumidification device 300 according to the detection value of the humidity sensor 800 . For example, when the detection value of the humidity sensor 800 exceeds the preset humidity threshold, it may be determined to activate the condensation dehumidification device 300 to ensure that the humidity of the storage space 222 is below the humidity threshold.
冷凝除湿装置300可以为热电装置,例如利用电能进行热量调节的装置,在电流的作用下,冷凝部320放热从而形成冷凝除湿装置300的低温部。例如,冷凝除湿装置300可以为热电制冷器。The condensation dehumidification device 300 may be a thermoelectric device, such as a device that uses electric energy to regulate heat. Under the action of electric current, the condensation part 320 releases heat to form a low temperature part of the condensation dehumidification device 300 . For example, the condensation dehumidification device 300 may be a thermoelectric cooler.
加热装置400可以为电加热元件,例如加热丝、加热片、加热环、加热棒或者加热管等任意电加热元件。The heating device 400 may be an electric heating element, such as any electric heating element such as a heating wire, a heating sheet, a heating ring, a heating rod or a heating tube.
在一些可选的实施例中,冷凝部320的表面形成倾斜的冷凝面,以便于冷凝水汇集。水蒸气在冷凝部320表面冷凝之后,可以快速地汇集至冷凝面的低处,使得冷凝面的大部分表面裸露出来,这可以提高冷凝部320与空气的有效接触面积,从而提高水蒸气的冷凝效率。例如,冷凝部320可以为板状,其冷凝面可以倾斜设置于储物空间222内。冷凝面的倾斜角度和倾斜方向可以根据实际需要进行设置,例如可以为由前向后倾斜5~30°,或者可以为由横线一侧向另一侧倾斜5~30°等。In some optional embodiments, the surface of the condensing part 320 forms an inclined condensing surface to facilitate the collection of condensed water. After the water vapor condenses on the surface of the condensation part 320, it can quickly gather to the lower part of the condensation surface, so that most of the surface of the condensation surface is exposed, which can increase the effective contact area between the condensation part 320 and the air, thereby improving the condensation of water vapor. efficiency. For example, the condensing part 320 may be plate-shaped, and its condensing surface may be obliquely disposed in the storage space 222 . The inclination angle and inclination direction of the condensation surface can be set according to actual needs, for example, it can be inclined from front to back by 5-30°, or from one side of the horizontal line to the other side by 5-30°, etc.
冷凝部320在储物空间222内的位置可以根据实际的空间布局要求进行 任意设置,例如可以设置于储物空间222的顶部、底部、中部或者侧部等。冷凝部320的表面可以指冷凝部320面朝储物空间222的一面。当冷凝部320设置于储物空间222的底部时,冷凝部320的表面为其上表面。The position of the condensation unit 320 in the storage space 222 can be set arbitrarily according to the actual space layout requirements, for example, it can be set on the top, bottom, middle or side of the storage space 222. The surface of the condensation part 320 may refer to a side of the condensation part 320 facing the storage space 222 . When the condensation part 320 is disposed at the bottom of the storage space 222 , the surface of the condensation part 320 is its upper surface.
在一些可选的实施例中,冷凝面的倾斜方式可以进行变换。例如,冷凝面可以自冷凝部320的横向两端向中部倾斜向下延伸,以使冷凝部320的中部形成供冷凝水汇集的汇流槽340。也就是说,本实施例的冷凝面并非沿同一方向倾斜,而是沿相对的两个不同方向进行倾斜,从而形成位于冷凝部320中部的汇流槽340。例如,冷凝面的横截面大致呈V型。In some optional embodiments, the inclination of the condensation surface can be changed. For example, the condensing surface may extend downwards from both lateral ends of the condensing part 320 toward the middle, so that the central part of the condensing part 320 forms a confluence groove 340 for collecting condensed water. That is to say, the condensing surface of this embodiment is not inclined in the same direction, but is inclined in two opposite directions, so as to form the confluence groove 340 located in the middle of the condensing part 320 . For example, the cross-section of the condensation surface is roughly V-shaped.
采用上述结构,冷凝部320在对水蒸气进行冷凝的同时,可将形成的冷凝水汇集至汇流槽340,这便于集中排出冷凝水。With the above structure, the condensing part 320 can collect the formed condensed water to the confluence tank 340 while condensing the water vapor, which facilitates centralized discharge of the condensed water.
需要说明的是,“前”“后”“上”“下”“横”等指示方向或位置关系的术语是基于附图所示的方向或位置关系,这仅仅是为了便于描述,而不是指示或暗示所描述的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。It should be noted that terms such as "front", "rear", "upper", "lower" and "horizontal" indicating direction or positional relationship are based on the direction or positional relationship shown in the drawings, which are only for convenience of description, rather than indicating Or imply that the described device or element must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the present invention.
在一些可选的实施例中,冰箱10进一步地还包括导流装置500,其形成有用于连通汇流槽340并延伸至储物空间222外的导流通道510,配置成将汇集至汇流槽340的冷凝水导引至储物空间222外。例如,导流通道510可以延伸至冰箱10的接水盘或者压机仓,以将冷凝水导引至接水盘或者压机仓内,使冷凝水可与接水盘内的积水一同导出或者使冷凝水直接在压机仓内蒸发。导流装置500可以为输液管,其一端连通汇流槽340,另一端连通接水盘或者压机仓。In some optional embodiments, the refrigerator 10 further includes a flow guiding device 500, which is formed with a flow guiding channel 510 for communicating with the confluence tank 340 and extending to the outside of the storage space 222, configured to collect The condensed water is guided to the outside of the storage space 222 . For example, the diversion channel 510 can extend to the water tray or the press chamber of the refrigerator 10, so as to guide the condensed water into the water tray or the press chamber, so that the condensed water can be exported together with the accumulated water in the water tray. Or make the condensed water evaporate directly in the compressor chamber. The flow guide device 500 can be a liquid infusion tube, one end of which is connected to the confluence tank 340, and the other end is connected to the water receiving tray or the press chamber.
在一些可选的实施例中,导流装置500设置于储物空间222的后侧。例如,箱体200内可以形成有位于储物空间222后侧的安装腔,用于安装蒸发器900等部件,导流装置500可以设置于该安装腔内。In some optional embodiments, the flow guiding device 500 is disposed at the rear side of the storage space 222 . For example, an installation cavity located behind the storage space 222 may be formed in the box body 200 for installing components such as the evaporator 900 , and the flow guide device 500 may be disposed in the installation cavity.
图3是图2所示的冰箱10的内部结构的侧视图,图中示出了储物空间222及其周围部件,为便于示例,该图为透视图。Fig. 3 is a side view of the internal structure of the refrigerator 10 shown in Fig. 2, in which the storage space 222 and its surrounding components are shown, and for the convenience of illustration, the figure is a perspective view.
汇流槽340自前至后地向下倾斜设置,储物空间222的背壁上开设有排水口,其连通汇流槽340与导流通道510,使得汇流槽340所汇集的冷凝水从排水口流出并流入导流通道510内。The confluence groove 340 is inclined downward from front to back, and a drain port is opened on the back wall of the storage space 222, which connects the confluence groove 340 and the diversion channel 510, so that the condensed water collected by the confluence groove 340 flows out from the drain port and into the guide channel 510.
采用上述结构,冷凝并附着在冷凝部320表面的冷凝水可在自身重力的作用下自动汇集至汇流槽340,汇流槽340所汇集的冷凝水可自动地流出排 水口并流入导流通道510,形成于冷凝部320表面的冷凝水可快速地、即时地排出。With the above-mentioned structure, the condensed water condensed and attached to the surface of the condensing part 320 can be automatically collected into the confluence tank 340 under the action of its own gravity, and the condensed water collected in the confluence tank 340 can automatically flow out of the drain outlet and flow into the diversion channel 510, The condensed water formed on the surface of the condensing part 320 can be quickly and immediately discharged.
由于冷凝部320的表面形成倾斜的冷凝面,该冷凝面自冷凝部320的横向两端向中部倾斜向下延伸,使得冷凝部320的中部形成供冷凝水汇集的汇流槽340,导流装置500可将汇流槽340内汇集的冷凝水及时地引出储物空间222,因此,本实施例的冰箱10有利于减少或避免储物空间222内产生的冷凝水因滞留而再次蒸发。Since the surface of the condensation part 320 forms an inclined condensation surface, the condensation surface extends obliquely downward from both lateral ends of the condensation part 320 to the middle part, so that the central part of the condensation part 320 forms a confluence groove 340 for collecting condensed water, and the flow guiding device 500 The condensed water collected in the confluence tank 340 can be led out of the storage space 222 in a timely manner. Therefore, the refrigerator 10 of this embodiment is beneficial to reduce or prevent the condensed water generated in the storage space 222 from evaporating again due to stagnation.
在一些可选的实施例中,冰箱10还可以进一步地包括气流促动装置600,设置于储物空间222内,配置成促使形成流经冷凝部320以及加热装置400的气流。气流促动装置600可以分别为风机,例如,离心风机,在一些实施例中,也可以变换为轴流风机,但不限于此。In some optional embodiments, the refrigerator 10 may further include an airflow actuating device 600 disposed in the storage space 222 and configured to promote the formation of an airflow passing through the condensation part 320 and the heating device 400 . The airflow actuating device 600 can be a fan, for example, a centrifugal fan, and in some embodiments, it can also be transformed into an axial fan, but is not limited thereto.
加热装置400设置于冷凝部320的下游。需要说明的是,术语“上游”和“下游”是指相对于流体路径中的流体流动的相对方向。例如,“上游”是指流体的来源方向,并且“下游”是指流体的目标方向。加热装置400设置于冷凝部320的下游是指,在气流促动装置600的作用下,储物空间222内的气流先流经冷凝部320,之后再流经加热装置400,从而使这部分气流吸热并升温。The heating device 400 is disposed downstream of the condensation part 320 . It should be noted that the terms "upstream" and "downstream" refer to relative directions with respect to fluid flow in a fluid path. For example, "upstream" refers to the source direction of the fluid, and "downstream" refers to the target direction of the fluid. The fact that the heating device 400 is arranged downstream of the condensation part 320 means that, under the action of the airflow actuator 600, the airflow in the storage space 222 first flows through the condensation part 320, and then flows through the heating device 400, so that this part of the airflow Absorb heat and heat up.
由于流经冷凝部320之后的气流湿度较低,因此,将加热装置400设置在冷凝部320的下游,并使加热装置400加热流经冷凝部320之后的空气,可减少或避免加热装置400发生凝露现象。Since the humidity of the airflow after passing through the condensation part 320 is low, the heating device 400 is arranged downstream of the condensation part 320, and the heating device 400 is used to heat the air flowing through the condensation part 320, which can reduce or avoid the occurrence of Condensation phenomenon.
冷凝除湿装置300和加热装置400分别在通电后启动。也就是说,通过对冷凝除湿装置300和加热装置400的通电状态进行调节,即可控制二者的启动和关闭。The condensation dehumidification device 300 and the heating device 400 are respectively started after being powered on. That is to say, by adjusting the energization states of the condensation dehumidification device 300 and the heating device 400 , the startup and shutdown of the two can be controlled.
在一些可选的实施例中,箱体200内还形成有回风风道,其通过回风口242与储物空间222连通,配置成将流经冷凝部320之后的回风气流再次导引至储物空间222。加热装置400设置于回风风道内。In some optional embodiments, a return air duct is also formed in the box body 200, which communicates with the storage space 222 through the return air port 242, and is configured to guide the return air flow after passing through the condensation part 320 to Storage space 222. The heating device 400 is arranged in the return air duct.
也就是说,加热装置400并未设置在储物空间222内,这可以减少或避免加热装置400对储物空间222内的其他空气(未流经冷凝部320的空气)进行加热而导致储物空间222产生温度波动。回风口242位于储物空间222的侧壁上,例如,可以设置在储物空间222的侧壁的底部区段,回风风道可以自回风口242向上延伸至储物空间222的顶部区段,并与储物空间222的 顶部区段连通,以便将回风气流再次导引至储物空间222。That is to say, the heating device 400 is not arranged in the storage space 222, which can reduce or prevent the heating device 400 from heating other air in the storage space 222 (air that has not flowed through the condensation part 320) and cause storage The space 222 generates temperature fluctuations. The return air outlet 242 is located on the side wall of the storage space 222, for example, can be arranged on the bottom section of the side wall of the storage space 222, and the return air duct can extend upward from the return air opening 242 to the top section of the storage space 222 , and communicate with the top section of the storage space 222 so as to guide the return air flow to the storage space 222 again.
在一些进一步的实施例中,加热装置400沿流经回风风道的气流方向延伸设置,这可使回风气流与加热装置400的放热面充分接触,提高加热装置400的加热效率。例如,加热装置400可以为加热片,回风通道内的回风气流可以沿加热装置400的片状表面流动。In some further embodiments, the heating device 400 is extended along the airflow direction flowing through the return air duct, which can make the return air flow fully contact with the heat release surface of the heating device 400 and improve the heating efficiency of the heating device 400 . For example, the heating device 400 may be a heating sheet, and the return air flow in the return air channel may flow along the sheet-shaped surface of the heating device 400 .
在一些可选的实施例中,回风风道具有第一纵向区段244、第二纵向区段246以及横向区段248。In some optional embodiments, the air return duct has a first longitudinal section 244 , a second longitudinal section 246 and a transverse section 248 .
