The thawing device 10 includes a radio frequency electromagnetic wave generating device 20 , a casing 100 , and a thawing chamber 302 inside the casing 100 for receiving objects to be thawed. The radio frequency electromagnetic wave generating device 20 is used for applying radio frequency electromagnetic waves to the thawing chamber 302 to thaw the object to be thawed in the thawing chamber 302 . The casing 100 has an electromagnetic wave shielding layer for preventing radio frequency electromagnetic waves from leaking out of the thawing chamber 302 .

壳体100具有连通解冻腔室302内部和外部的通风口1001,通风口1001的尺寸被设计成使发射入解冻腔室302的射频电磁波不能穿过通风口1001。The housing 100 has a vent 1001 communicating with the inside and outside of the thawing chamber 302 , and the size of the vent 1001 is designed so that radio frequency electromagnetic waves emitted into the thawing chamber 302 cannot pass through the vent 1001 .

射频电磁波产生装置20包括射频电源200以及与射频电源200连接的射频发射件201。射频发射件201用于向解冻腔室302施加射频电磁波以对位于解冻腔室302内的待解冻物进行解冻。The radio frequency electromagnetic wave generating device 20 includes a radio frequency power source 200 and a radio frequency transmitter 201 connected with the radio frequency power source 200 . The radio frequency transmitter 201 is used for applying radio frequency electromagnetic waves to the thawing chamber 302 to thaw the object to be thawed in the thawing chamber 302 .

在一个实施例中,射频发射件201可以位于壳体100内。壳体100可以具有用于收纳射频发射件201安装腔室301,安装腔室301和解冻腔室302可通过可透射射频电磁波的分隔件101分隔。例如,分隔件101将由壳体100限定的腔室300分隔为安装腔室301和解冻腔室302。In one embodiment, the radio frequency transmitter 201 may be located in the casing 100 . The casing 100 may have an installation chamber 301 for accommodating the radio frequency transmitter 201 , and the installation chamber 301 and the thawing chamber 302 may be separated by a partition 101 that can transmit radio frequency electromagnetic waves. For example, the partition 101 partitions the chamber 300 defined by the housing 100 into an installation chamber 301 and a thawing chamber 302 .

射频发射件201可以置于安装腔室301内部。分隔件101可采用隔离电和/或热、且可透射射频电磁波的绝缘材质,例如塑料。The RF transmitter 201 can be placed inside the installation chamber 301 . The spacer 101 can be made of an insulating material such as plastic that isolates electricity and/or heat and transmits radio frequency electromagnetic waves.

通过在解冻装置中的射频发射件可实现均匀解冻,减少被解冻食物汁液流失。通过分隔件分隔安装腔室的射频发射件和解冻腔室的被加热食物,避免加热过程中射频波泄露以及避免污染射频发射件。Uniform thawing can be realized through the radio frequency transmitter in the thawing device, reducing the loss of thawed food juice. The radio frequency transmitter in the installation chamber and the heated food in the thawing chamber are separated by the partition to avoid leakage of radio frequency waves and contamination of the radio frequency transmitter during the heating process.

壳体100具有用以防止射频电磁波从解冻腔室302外泄的电磁波屏蔽层。在一个实施例中,壳体100可以为塑料材质,并且具有用于屏蔽电磁波的金属层。金属层可以例如通过电镀、喷涂等工艺附于塑料基壁。在另一个实施例中,壳体100也可以由能屏蔽电磁波的金属材料制成而形成电磁波屏蔽层。The casing 100 has an electromagnetic wave shielding layer for preventing radio frequency electromagnetic waves from leaking out of the thawing chamber 302 . In one embodiment, the casing 100 may be made of plastic and has a metal layer for shielding electromagnetic waves. The metal layer can be attached to the plastic base wall, for example, by electroplating, spraying, or the like. In another embodiment, the casing 100 may also be made of a metal material capable of shielding electromagnetic waves to form an electromagnetic wave shielding layer.

如图6所示,解冻腔室302具有取放口104,壳体100包括可用以开闭解冻腔室302的门102。As shown in FIG. 6 , the thawing chamber 302 has an opening 104 , and the casing 100 includes a door 102 that can be used to open and close the thawing chamber 302 .

在一个实施例中,门102可以可动地连接于壳体100的主体部分。例如门102可旋转地连接于壳体100的主体部分。在另一个实施例中,门102可滑动地连接于壳体100的主体部分。In one embodiment, the door 102 may be movably connected to the main body portion of the housing 100 . For example, the door 102 is rotatably connected to the main body portion of the housing 100 . In another embodiment, the door 102 is slidably connected to the main body portion of the housing 100 .

在一个替换的实施例中,解冻装置10包括适于可选地推入解冻腔室302或从解冻腔室302拉出的抽屉式容器。抽屉式容器的前壁形成用于关闭开口104的门102。In an alternative embodiment, the thawing device 10 comprises a drawer container adapted to be selectively pushed into or pulled out of the thawing chamber 302 . The front wall of the drawer container forms a door 102 for closing an opening 104 .

门102也可为塑料材质,在其背面有金属层,用于屏蔽射频电磁波。该腔室门材料也可以为能屏蔽电磁波的金属材料。The door 102 can also be made of plastic with a metal layer on its back for shielding radio frequency electromagnetic waves. The chamber door material can also be a metal material capable of shielding electromagnetic waves.

在一个实施例中,射频电源200可以产生射频频率介于13.56MHz~433MHz之间的电磁波,例如13.56MHz,40MHz或者433MHz。根据实验证明,该区间频率的电磁波能够更好地解冻食物。In one embodiment, the radio frequency power supply 200 can generate electromagnetic waves with a radio frequency between 13.56 MHz and 433 MHz, such as 13.56 MHz, 40 MHz or 433 MHz. According to the experiment, the electromagnetic wave with the frequency in this range can better defrost the food.

在一个实施例中,射频电源200可以产生功率介于100W~400W之间的射频电磁波,以利于解冻。In one embodiment, the radio frequency power supply 200 can generate radio frequency electromagnetic waves with a power between 100W-400W to facilitate thawing.

如图2所示,射频电源200可以包括屏蔽电磁波的金属壳体,材质为铝合金或者不绣钢。在金属壳体可以设置有多个直径不大于5mm的孔,用于给射频电源通风降温。As shown in FIG. 2 , the radio frequency power supply 200 may include a metal shell shielding electromagnetic waves, made of aluminum alloy or stainless steel. A plurality of holes with a diameter not greater than 5mm may be provided in the metal shell for ventilation and cooling of the radio frequency power supply.

在射频电源200内可以设置有交直流(AC/DC)电源2001,例如将220V交流电源转换为0~36V、0~14A直流电和0~5V、0~3A直流电源。An AC/DC power supply 2001 may be provided in the radio frequency power supply 200, for example, a 220V AC power supply may be converted into a 0-36V, 0-14A DC power supply and a 0-5V, 0-3A DC power supply.

在射频电源200内可以设置有射频产生和控制单元2002,可以产生200-300W,13.56MHz~433MHz的射频段电磁波。A radio frequency generation and control unit 2002 may be provided in the radio frequency power supply 200, capable of generating 200-300W, 13.56MHz-433MHz radio frequency electromagnetic waves.

如图3,射频电源200位于壳体100外。射频发射件201可通过射频线缆2011与射频电源200连接。As shown in FIG. 3 , the radio frequency power supply 200 is located outside the casing 100 . The radio frequency transmitter 201 can be connected to the radio frequency power supply 200 through a radio frequency cable 2011 .

在一个实施例中,射频发射件201可以是板状的射频天线,能够使得射频波通过射频天线均匀的辐射到解冻腔室302,从而作用于被解冻食物。In one embodiment, the radio frequency emitting element 201 may be a plate-shaped radio frequency antenna, which can radiate radio frequency waves uniformly to the thawing chamber 302 through the radio frequency antenna, thereby acting on the food to be thawed.

进一步地,参照图3,射频电磁波产生装置20可包括连接射频电源200和射频发射件201的射频线缆2011。在一个实施例中,射频线缆2011可穿过壳体100连接射频发射件201和射频电源200。射频线缆2011可以通过连接器2012与壳体100固定。Further, referring to FIG. 3 , the radio frequency electromagnetic wave generating device 20 may include a radio frequency cable 2011 connecting the radio frequency power supply 200 and the radio frequency transmitter 201 . In one embodiment, the radio frequency cable 2011 can pass through the housing 100 to connect the radio frequency transmitter 201 and the radio frequency power supply 200 . The radio frequency cable 2011 can be fixed with the housing 100 through a connector 2012 .

进一步地,本发明实施例还包括设置在解冻腔室302下部内壁的第二绝缘层101′,第二绝缘层101′用于隔离被解冻食物和解冻腔室302的下壁,使得作用于解冻腔室302的射频波能够更好地作用于被解冻食物。Further, the embodiment of the present invention also includes a second insulating layer 101' disposed on the lower inner wall of the thawing chamber 302. The second insulating layer 101' is used to isolate the food to be thawed from the lower wall of the thawing chamber 302, so that it acts on the thawing chamber. The radio frequency waves of the chamber 302 are better able to act on the defrosted food.

参照图4,壳体100具有电磁波屏蔽层,壳体100具有穿透壳体100并连通解冻腔室302内外的通风口1001。通风口1001的尺寸被设计成使发射入解冻腔室302的射频电磁波不能穿过通风口,从而当射频电磁波施加于解冻腔室302时,射频电磁波不会经由通风口1001泄露。因此通风口1001保持常开成为可能。Referring to FIG. 4 , the casing 100 has an electromagnetic wave shielding layer, and the casing 100 has a vent 1001 penetrating through the casing 100 and communicating with the inside and outside of the thawing chamber 302 . The size of the vent 1001 is designed so that the radio frequency electromagnetic wave emitted into the thawing chamber 302 cannot pass through the vent, so that when the radio frequency electromagnetic wave is applied to the thawing chamber 302 , the radio frequency electromagnetic wave will not leak through the vent 1001 . It is therefore possible for the vent 1001 to remain normally open.

在一个实施例中,通风口1001为常开,因而在射频电磁波施加于解冻腔室302时,通风口1001也保持打开。通过设计常开、小尺寸通风口1001,因此可以不必额外增加用于关闭通风口1001的阀,从而有利于简化解冻装置的构造并增加解冻装置的空间效率。In one embodiment, the vent 1001 is normally open, so when radio frequency electromagnetic waves are applied to the thawing chamber 302, the vent 1001 also remains open. By designing the vent 1001 that is normally open and small in size, it is not necessary to add an additional valve for closing the vent 1001 , thereby simplifying the structure of the thawing device and increasing the space efficiency of the thawing device.

通风口1001的尺寸小于射频发射件201所发射射频波的波长。在一个实施例中,通风口1001在壳体100的内表面处的边界线任意两点之间的直线距离不大于6毫米。这特别有利于防止射频电磁波从通风口1001泄露。通风口1001可以是直径不大于6毫米的圆孔,。在一个实施例中通风口1001的直径可介于2毫米到6毫米之间,优选地是3毫米。The size of the vent 1001 is smaller than the wavelength of the radio frequency wave emitted by the radio frequency emitting element 201 . In one embodiment, the straight-line distance between any two points on the boundary line of the vent 1001 at the inner surface of the housing 100 is not greater than 6 mm. This is particularly advantageous in preventing leakage of radio frequency electromagnetic waves from the vent 1001 . The vent 1001 may be a circular hole with a diameter not greater than 6 mm. In one embodiment the diameter of the vent 1001 may be between 2mm and 6mm, preferably 3mm.

进一步地,可以在壳体100上设置若干通风口1001,间隔分布于壳体100。这些通风口1001可以以阵列排布。Further, several vents 1001 may be provided on the casing 100 and distributed in the casing 100 at intervals. These vents 1001 may be arranged in an array.

在一个实施例中,壳体100可包括第一壁3001和第二壁3002,通风口1001可以分别分布在这两个壁上。In one embodiment, the casing 100 may include a first wall 3001 and a second wall 3002, and the vents 1001 may be respectively distributed on the two walls.

在一个实施例中,第一壁3001和第二壁3002相对设置,以便在有风作用时能够更好的流通。如图4所示,可以设置在第一壁3001和第二壁3002(如门102)上,且两者相对设置。In one embodiment, the first wall 3001 and the second wall 3002 are arranged opposite to each other so as to allow better circulation when there is wind. As shown in FIG. 4 , it can be arranged on the first wall 3001 and the second wall 3002 (such as the door 102 ), and the two are oppositely arranged.

通过在壳体100上设置限制尺寸的通风口1001,使得解冻腔室302与外部连通的同时也不至于有射频波辐射。因此,在可以增强解冻腔室302和外部流体联通效果的同时,不必额外设置用以关闭通风口1001的风门成为可能。By setting the ventilation opening 1001 with a limited size on the casing 100, the thawing chamber 302 is communicated with the outside and at the same time there is no radio frequency radiation. Therefore, while the communication effect between the thawing chamber 302 and the external fluid can be enhanced, it is possible to not need to additionally provide a damper for closing the vent 1001 .

在解冻装置10被集成在冰箱的实施例中,即使用户在解冻食物后没有及时取出被解冻食物,解冻腔室可以与冰箱的储藏室解冻装置外连通,进入低温状态,防止长时间未取出而变质。此外,解冻腔室302被用作普通的储藏区域也成为可能。In the embodiment where the thawing device 10 is integrated in the refrigerator, even if the user does not take out the thawed food in time after thawing the food, the thawing chamber can communicate with the storage room of the refrigerator outside the thawing device and enter a low temperature state to prevent the food from being frozen if it is not taken out for a long time. spoiled. Furthermore, it is also possible that the thawing chamber 302 is used as a general storage area.

该解冻装置10还包括检测单元103,用于检测腔室门102是否打开或关闭,用于通过门102打开的电信号控制射频电源关闭。检测单元103可以是传感器。检测单元103可设置在门102开合处。The thawing device 10 further includes a detection unit 103 for detecting whether the chamber door 102 is opened or closed, and for controlling the radio frequency power to be turned off through the electric signal of the door 102 being opened. The detection unit 103 may be a sensor. The detection unit 103 can be arranged at the opening and closing position of the door 102 .

图5是冰箱50的正面剖视图。冰箱50包括解冻装置10。具体地,冰箱50包括储藏室501以及用于关闭所述储藏室的箱体门502(图6)。解冻装置10设置在储藏室501内部。储藏室501可以是冷冻室、冷藏室、变温室等任何一个储藏室。在一个实施例中,解冻冷淡装置10可以设置在储藏室501的顶部。FIG. 5 is a front sectional view of refrigerator 50 . The refrigerator 50 includes the defrosting device 10 . Specifically, the refrigerator 50 includes a storage room 501 and a cabinet door 502 ( FIG. 6 ) for closing the storage room. The thawing device 10 is disposed inside the storage room 501 . The storage room 501 may be any storage room such as a freezer room, a refrigerator room, or a temperature-changing room. In one embodiment, the thawing and cooling device 10 may be disposed on the top of the storage room 501 .

在一个实施例中,如图6所示冰箱50的俯视剖面图,冰箱50还包括门102的旋转方向与箱体门502的旋转方向一致。In one embodiment, as shown in FIG. 6 , which is a top sectional view of a refrigerator 50 , the refrigerator 50 further includes that the rotation direction of the door 102 is consistent with the rotation direction of the cabinet door 502 .

此外冰箱还可以是上下双门冰箱、多门冰箱或其他类型的冰箱。In addition, the refrigerator can also be a refrigerator with upper and lower double doors, a multi-door refrigerator or other types of refrigerators.

具体的,图7是冰箱左侧剖视图,冰箱50包括风道5011,风道5011包括向储藏室501输入冷空气的出风口5012。解冻装置10的至少一个通风口1001设置于壳体100的壁,例如第一壁3001。在一个实施例中,第一壁3001面向出风口5012。因而使得解冻装置10的通风口1001与储藏室501连通,使得储藏室501的冷空气可以经过通风口1001进入解冻腔室302。能够利用冰箱储藏室的低温环境,使得被解冻食物的内外温差减少,实现均匀解冻。Specifically, FIG. 7 is a cross-sectional view of the left side of the refrigerator. The refrigerator 50 includes an air duct 5011 , and the air duct 5011 includes an air outlet 5012 for inputting cold air into the storage room 501 . At least one vent 1001 of the thawing device 10 is disposed on a wall of the casing 100 , such as the first wall 3001 . In one embodiment, the first wall 3001 faces the air outlet 5012 . Therefore, the vent 1001 of the thawing device 10 is communicated with the storage chamber 501 , so that the cold air in the storage chamber 501 can enter the thawing chamber 302 through the vent 1001 . The low-temperature environment in the storage room of the refrigerator can be used to reduce the temperature difference between the inside and outside of the thawed food and achieve uniform thawing.

因此,根据本发明一个实施例的冰箱,可以实施以下方法。当启动冰箱50的解冻功能后,解冻装置10的射频发射件201向位于冰箱的储藏室501内的解冻腔室302施加射频电磁波。在射频电磁波被施加于所述解冻腔室302时,通过位于解冻腔室302的壁上的通风口1001流体连通解冻腔室302和储藏室501。Therefore, according to the refrigerator according to one embodiment of the present invention, the following method can be implemented. When the thawing function of the refrigerator 50 is activated, the radio frequency transmitter 201 of the thawing device 10 applies radio frequency electromagnetic waves to the thawing chamber 302 located in the storage room 501 of the refrigerator. When radio frequency electromagnetic waves are applied to the thawing chamber 302 , the thawing chamber 302 and the storage chamber 501 are in fluid communication through the vent 1001 located on the wall of the thawing chamber 302 .

在一个可能的实施例中,通风口1001在所述腔室壁3001的内表面处的边界线任意两点之间的直线距离不大于6毫米。In a possible embodiment, the linear distance between any two points on the boundary line of the vent 1001 at the inner surface of the chamber wall 3001 is not greater than 6 mm.

在一个可能的实施例中,解冻后的食物温度介于-3±1℃之间。下面详细说明解冻装置10的示范性工作方式。In a possible embodiment, the temperature of the thawed food is between -3±1°C. An exemplary working mode of the thawing device 10 will be described in detail below.

如图8所示,当解冻装置10解冻模式被选择时,判断解冻腔室302的门102是否已经关闭。优选地,在解冻腔室302的门102处设置有感应开关103,根据感应开关的信号判断门102是否关闭。As shown in FIG. 8 , when the thawing mode of the thawing device 10 is selected, it is determined whether the door 102 of the thawing chamber 302 has been closed. Preferably, an induction switch 103 is provided at the door 102 of the thawing chamber 302, and it is determined whether the door 102 is closed according to a signal of the induction switch.

当门102已经关闭,控制射频电源200开始工作。然后根据解冻腔室302的负载情况控制解冻程序。When the door 102 is closed, the RF power supply 200 is controlled to work. Then the thawing program is controlled according to the load of the thawing chamber 302 .

在一个实施例中,首先判断解冻腔室302内是否有负载。例如,在系统中预置第一阈值,当射频发射件的射频功率损耗满足该阈值时则认为有负载,否则没有负载。但没有负载时,控制射频电源200停止工作。当有负载时,进一步判断该负载是否超过最大负载阈值。In one embodiment, it is first determined whether there is a load in the thawing chamber 302 . For example, a first threshold is preset in the system, and when the radio frequency power loss of the radio frequency transmitter meets the threshold, it is considered that there is a load, otherwise there is no load. But when there is no load, the radio frequency power supply 200 is controlled to stop working. When there is a load, it is further judged whether the load exceeds the maximum load threshold.

在负载超过最大负载阈值时,控制射频电源200停止工作。否则,在解冻的过程中,进一步判断当前被解冻食物的温度是否满足预设温度,当满足预设温度时解冻完成。其中,如前文描述的,可根据射频波的功率损耗和食物温度之间的对应关系获取当前被解冻食物的温度。When the load exceeds the maximum load threshold, the RF power supply 200 is controlled to stop working. Otherwise, during the thawing process, it is further judged whether the temperature of the currently thawed food meets the preset temperature, and the thawing is completed when the preset temperature is met. Wherein, as described above, the temperature of the currently thawed food can be obtained according to the correspondence between the power loss of the radio frequency wave and the temperature of the food.

负载是解冻腔室内射频功率的损耗。具体的,解冻过程的原理是利用水分子在不同温度状态下对射频功率的吸收不同。介电损耗是指电介质在交变电场中,由于消耗部分电能而使电介质本身发热的现象。在固定频率下,不同温度水分子的介电损耗是不同的,通过功率损耗可以得到介电损耗,由介电损耗就可以知道当前食物温度。通过功率损耗和食物温度之间的关系可以精确地判断是否有负载,负载是否超过设定的最大负载,以及将解冻后的食物温度控制在-3±1℃之内。Load is the loss of RF power in the thawing chamber. Specifically, the principle of the thawing process is to use water molecules to absorb radio frequency power differently under different temperature states. Dielectric loss refers to the phenomenon that the dielectric itself heats up due to the consumption of part of the electric energy in the alternating electric field. At a fixed frequency, the dielectric loss of water molecules at different temperatures is different. The dielectric loss can be obtained through the power loss, and the current food temperature can be known from the dielectric loss. Through the relationship between power loss and food temperature, it can accurately judge whether there is a load, whether the load exceeds the set maximum load, and control the temperature of the defrosted food within -3±1°C.
