DETAILED DESCRIPTION

[0033] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0034] The embodiment of the present invention first provides a low-temperature and high-humidity thawing device 10. Figure 1 is a structural diagram of a low-temperature and high-humidity thawing device 10 according to an embodiment of the present invention. Figure 2 is a cross-sectional view of a low-temperature and high-humidity thawing device 10 according to an embodiment of the present invention, referring to Figure 1 and Figure 2 The low temperature and high humidity thawing device 10 may include a thawing box 140 and a flow promotion component 110. The thawing box 140 defines a thawing chamber 143 for placing the object to be thawed, and the thawing chamber 143 has an air supply port 144, an air return port 145, and a drainage duct 146 connecting the air supply port 144 and the air return port 145. The flow promotion component 110 is configured to controllably blow the thawing airflow toward the object to be thawed through the air supply port 144, so that the thawing airflow flows back to the flow promotion component 110 from the air return port 145 through the drainage duct 146.

[0035] In this embodiment, by providing the air supply port 144, the air return port 145 and the air flow channel 146, when the flow promotion component 110 blows the thawing airflow toward the object to be thawed through the air supply port 144, a circulating airflow flowing through the object to be thawed can be formed in the thawing chamber 143. This is conducive to improving the flow smoothness of the thawing airflow, accelerating the heat exchange efficiency between the thawing airflow and the object to be thawed, and thus improving the thawing speed of the object to be thawed.

[0036] The air supply port 144 may be formed on the top wall of the thawing chamber 143, and the air return port 145 may be formed on the side wall of the thawing chamber 143. That is, the present embodiment adopts the top air supply-side air return mode to circulate the thawing air flow. The flow promotion component 110 may be arranged at the air supply port 144, or may be arranged in the air duct 146.

[0037] In some optional embodiments, the low-temperature and high-humidity thawing device 10 may include a thawing box 140 and a thawing door 150. The thawing box 140 defines a forward-opening thawing chamber 143. The thawing door 150 is pivotally connected to the thawing box 140 for opening and closing the thawing chamber 143 for users to take in and put in the thawed items.

[0038] The thawing door 150 can be a single-open door or a double-open door, and the single-open door is shown in the drawings. A vertically extending pivot shaft is provided between the thawing door 150 and the left or right side of the thawing box 140, so that the thawing door 150 can be rotated and opened toward the left or right side of the thawing box 140. Alternatively, a horizontally extending pivot shaft is provided between the thawing door 150 and the top of the thawing box 140, so that the thawing door 150 can be flipped and opened toward the top of the thawing box 140, and the thawing door 150 shown in the drawings is flipped upward to open.

[0039] In order to keep the thawing door 150 stable after turning upward, the front end surface of the thawing box 140 can be designed as an inclined surface that gradually tilts forward from top to bottom. In this way, after the thawing door 150 is opened, the angle of its upward turning will be greater than 90°, and the center of gravity of the thawing door 150 is relatively backward, so that it will not automatically turn forward and fall.

[0040] The thawing box 140 may include an outer box 141 and an inner frame 142. Figure 3 is an exploded view of the outer box 141 and the inner frame 142 of the thawing box 140 according to one embodiment of the present invention, referring to Figure 3 The inner frame 142 is disposed inside the outer box 141, and the inner frame 142 defines the above-mentioned thawing chamber 143. The air supply port 144 is provided on the top wall of the inner frame 142, and the air return port 145 is provided on the side wall of the inner frame 142. A drainage air duct 146 is formed between the side wall and / or the top wall of the inner frame 142 and the outer box 141.

[0041] In some examples, the air supply port 144 is disposed at the center of the top wall of the inner frame 142, and the number of the return air ports 145 is two, and the two return air ports 145 are respectively disposed at the bottom of the two side walls of the inner frame 142. A drainage duct 146 is formed between the two side walls of the inner frame 142 and the two side walls of the outer box 141, and between the top wall of the inner frame 142 and the top wall of the outer box 141. The drainage duct 146 is equivalent to an inverted U shape, and is buckled on both sides and the top of the thawing chamber 143.

[0042] The flow promotion component 110 can be further configured to make the air flow velocity of the thawing airflow blowing to the object to be thawed be 0.5m / s to 2.5m / s. For example, 0.5m / s, 0.8m / s, 1.0m / s, 1.2m / s, 1.5m / s, 1.8m / s, 2.0m / s, 2.5m / s, etc. It has been confirmed by experiments that by controlling the air flow velocity within the above range, on the one hand, the thawing airflow can have a certain blowing force when blowing to the object to be thawed, thereby ensuring the heat exchange effect; on the other hand, it can prevent the air flow velocity from being too high, and minimize the drying effect of the thawing airflow on the object to be thawed.

[0043] In the embodiment shown in the drawings of the present invention, the flow promotion component 110 is an axial flow fan, which is arranged at the air supply port 144 to blow air from top to bottom toward the object to be thawed. The length of the air supply path between the flow promotion component 110 and the thawing area can be set to 5cm to 40cm. Since the wind speed at the proximal end of the flow promotion component 110 is relatively large and the wind speed at the distal end is relatively small, therefore, in practical applications, the wind speed of the flow promotion component 110 and the length of the air supply path between the flow promotion component 110 and the object to be thawed should be reasonably configured to ensure that the air flow speed of the thawing airflow blown to the object to be thawed meets the requirements.

[0044] Although the flow promotion component 110 shown in the present invention is an axial flow fan, without departing from the spirit and essence of the present invention, those skilled in the art may replace the axial flow fan with a centrifugal fan and make the air flow velocity of the thawing air flow blown to the thawing area consistent with the parameter range disclosed in the present invention, which should also fall within the scope of protection of the present invention.

[0045] The low temperature and high humidity thawing device 10 may further include a heating assembly 120, which may be configured to heat the internal space of the thawing chamber 143 so that the internal temperature of the thawing chamber 143 is 10°C to 30°C. For example, 10°C, 15°C, 18°C, 20°C, 25°C, 28°C, 30°C, etc. In this way, by adjusting the internal temperature of the entire thawing chamber 143, the temperature of the thawing airflow may be indirectly adjusted, thereby adjusting the heat exchange between the thawing airflow and the object to be thawed, and ultimately ensuring that the thawing speed of the object to be thawed is appropriate.

[0046] In some other examples, the heating device can also be configured to directly heat the thawing airflow blown by the flow promotion component 110, so that the airflow temperature when the thawing airflow blows to the object to be thawed is 10°C to 30°C. For example, 10°C, 15°C, 18°C, 20°C, 25°C, 28°C, 30°C, etc. This method can more accurately ensure the airflow temperature when the thawing airflow exchanges heat with the object to be thawed, and more accurately control the thawing speed.

[0047] In this embodiment, the heating component 120 is arranged in the air duct 146. The heating component 120 is mainly used to heat the thawing airflow flowing back to the flow promotion component 110, so that when the thawing airflow is blown to the object to be thawed again through the flow promotion component 110, its airflow temperature can still meet the requirements.

[0048] Specifically, the heating assembly 120 may include a heat storage plate 121. The working process of the heat storage plate 121 includes a heat storage stage and a heat release stage. When the airflow in the drainage duct 146 needs to be heated, the heat storage plate 121 can be controlled to release heat, which is beneficial to saving heating costs.

[0049] The thermal conductivity of the heat storage plate 121 may be 0.026W / (m·K) to 400W / (m·K), and the phase transition point temperature may be -18°C to 30°C. The heat storage plate 121 with such thermal conductivity and phase transition point temperature can fully heat the thawing airflow flowing back to the flow promotion component 110, effectively ensuring that the airflow temperature of the thawing airflow when it is subsequently blown to the object to be thawed still meets the requirements.

[0050] The heat storage plate 121 can be arranged adjacent to one side of the flow promotion component 110, or around the flow promotion component 110, so that the thawing airflow can be directly blown by the flow promotion component 110 after being heated by the heat storage plate 121, shortening the flow length of the thawing airflow after heating, which is beneficial to reducing the heat loss of the thawing airflow during the flow process.

[0051] Furthermore, the heating assembly 120 may also include at least one heat dissipation fin 122. A heat transfer tube 123 is connected between the heat storage plate 121 and the heat dissipation fin 122. The heat storage plate 121 transfers the heat generated by it to the heat dissipation fin 122 through the heat transfer tube 123, thereby increasing its own heat dissipation area, thereby improving the heating efficiency and realizing rapid heating of the thawed airflow.

[0052] The heat storage plate 121 can be arranged in the upper section of the air flow channel 146 in the thawing chamber 143, and the number of heat dissipation plates can be two, which are respectively arranged in the sections on both sides of the air flow channel 146 in the thawing chamber 143, and a heat transfer pipe 123 is connected between each heat dissipation plate and the heat storage plate 121. In this way, the thawing airflow flowing back to the flow promotion component 110 from the return air ports 145 on both sides can be heated by the heat dissipation plates, thereby improving the uniformity of heating.

[0053] In some optional embodiments, the low-temperature and high-humidity thawing device 10 may also include a humidifying component 130, which is configured to supply humidified airflow into the thawing chamber 143 in a controlled manner, and utilize the humidified airflow to increase the internal humidity of the thawing chamber 143, thereby maintaining the surface of the thawed object moist and reducing the degree of air drying of the thawed object after thawing.

[0054] Specifically, refer to Figure 4 The humidification component 130 may include a water storage box 131 and an atomization head 132. The water storage box 131 is used to store humidification water. The atomization head 132 is connected to the inside of the water storage box 131 and is used to convert the humidification water into a humidified air flow.

[0055] The atomizing head 132 can be fixed to the water storage box 131, and the thawing box 140 can be pulled out or pushed in sync with the water storage box 131. In this way, when the atomizing head 132 fails, it can be pulled out of the thawing box 140 through the water storage box 131, so that the atomizing head 132 can be repaired and replaced.

[0056] The atomizer head 132 in this embodiment can be selected as a microporous atomizer head 132 with an operating frequency less than or equal to 120KHz, or it can be selected as a solid hole atomizer head 132 with an operating frequency greater than 1.7MHz. The capacity of the water storage box 131 can be 60ml~1000ml, and the atomization amount of the atomizer head 132 is 20ml / h~60ml / h to meet the thawing requirements.

[0057] Preferably, the atomizing head 132 is arranged toward the air supply path of the flow promoting component 110. In this way, the humidified airflow blown out by the atomizing head 132 can be mixed with the thawing airflow, thereby increasing the moisture content of the thawing airflow. Since the humidity of the thawing airflow is relatively high, the surface of the thawing object can be kept moist during the heat exchange process with the thawing object.

[0058] In some examples, a heating element such as a heating wire may be provided in the water storage box 131. The heating wire is mainly used to heat the humidification water so that the humidified airflow blown out of the atomizing head 132 has a certain temperature. In this embodiment, the airflow temperature of the humidified airflow is required to be less than 40°C. If the temperature of the humidified airflow is too high, the fine droplets carried by it are very likely to be vaporized, and a large loss will occur in the process of supplying to the thawing airflow, reducing the utilization rate of the humidified airflow.

[0059] In this embodiment, the airflow temperature of the humidified airflow can be consistent with the airflow temperature of the thawing airflow. In this way, when the humidified airflow is mixed with the thawing airflow, the airflow temperature of the thawing airflow will not be affected, ensuring that the airflow temperature of the thawing airflow when it is blown to the object to be thawed meets the requirements.

[0060] The water storage box 131 can be slidably connected to the front end of the thawing box 140. After the thawing door 150 is flipped upward and opened, the water storage box 131 can be exposed. The user can easily add humidification water to the water storage box 131 by pulling the water storage box 131 forward.

[0061] Specifically, a sliding groove 147 is provided at the front end of the inner frame 142 of the thawing box 140, and the sliding groove 147 extends along the depth direction of the thawing chamber 143, and the water storage box 131 is inserted into the sliding groove 147. The shape of the sliding groove 147 should be as compatible as possible with the shape of the water storage box 131, so that the water storage box 131 can remain stable after being pushed into the sliding groove 147.

[0062] The sliding groove 147 may be located above the thawing chamber 143, and its bottom is connected to the thawing chamber 143. After the water storage box 131 is fully pushed into the sliding groove 147, the water storage box 131 is located on the lower side of the flow promotion component 110, and at least partially extends into the thawing chamber 143. In this way, the atomizing head 132 can be fixed to the side of the water storage box 131 adjacent to the air supply path, so that the atomizing head 132 supplies humidified airflow toward the air supply path in the thawing chamber 143.

[0063] The two sides of the sliding groove 147 are provided with lap plates 148, and the two sides of the water storage box 131 can be supported on the lap plates 148. The lap plates 148 shown in the drawings are located at the bottom of the two sides of the sliding groove 147, and when the water storage box 131 is pushed into the sliding groove 147, its bottom is supported on the lap plates 148. In some other embodiments, the lap plates 148 can also be located in the middle of the two sides of the sliding groove 147, and accordingly, the two sides of the water storage box 131 are provided with lap grooves that cooperate with the lap plates 148.

[0064] A baffle is provided at the front end of the water storage box 131, and the lower edge of the baffle is lower than the top wall of the thawing chamber 143. That is, the lower edge of the baffle is lower than the upper edge of the forward opening, and when the water storage box 131 is fully pushed into the sliding groove 147, the user can buckle the lower edge of the baffle through the forward opening, thereby conveniently pulling the water storage box 131 forward.

[0065] Since the atomizing head 132 is fixed on the water storage box 131 and can be pulled forward with the water storage box 131, it is necessary to consider the power supply method of the atomizing head 132. The humidifying assembly 130 of this embodiment may also include a wireless power supply 133, which is used to connect the atomizing head 132 to an external power source and enable the atomizing head 132 to work in a controlled manner.

[0066] The wireless power supply 133 may include a transmitting coil 133a and a receiving coil 133b, wherein the transmitting coil 133a may be fixed to the top of the inner frame 142, and the receiving coil 133b may be fixed to the top of the water storage box 131. When the water storage box 131 is fully pushed into the sliding groove 147, the transmitting coil 133a and the receiving coil 133b are arranged opposite to each other up and down, and the interval between the two is less than 10 mm. Since the working principle of the wireless power supply 133 is well known to those skilled in the art, it will not be described here.

[0067] It should be noted that the straight-line distance that the atomizing head 132 supplies the humidified airflow to the air supply path can be 10mm to 300mm, for example 10mm, 20mm, 30mm, 50mm, etc., to reduce the loss before the humidified airflow is mixed with the thawing airflow, so that more droplets in the humidified airflow can be vaporized under the high temperature of the thawing airflow, and the unvaporized droplets can adhere to the surface of the to-be-thawed object at a desired wetting angle, thawing the to-be-thawed object by the latent heat of vaporization, maintaining the humidity on the surface of the to-be-thawed object, and ensuring the thawing quality of the to-be-thawed object.

[0068] Considering that the thawing water generated during the thawing process of the object to be thawed easily flows to the bottom wall of the thawing chamber 143, it is inconvenient to clean it later. Therefore, a tray assembly 160 can be arranged in the thawing chamber 143, and the object to be thawed can be placed in the tray assembly 160 for thawing. The tray assembly 160 stores the thawing water generated by the object to be thawed. After the thawing is completed, only the tray assembly 160 needs to be cleaned, thereby improving the user experience.

[0069] The present invention further provides a refrigerator 1, Figure 5 is a structural diagram of a refrigerator 1 according to an embodiment of the present invention, referring to Figure 5 The refrigerator 1 may generally include a body 20 and a door 30. The body 20 defines a storage compartment inside. The storage compartment may be configured as a refrigeration compartment, a freezing compartment, a variable temperature compartment, etc. according to the refrigeration temperature. Specifically, the number, function, layout, etc. of the storage compartment may be configured in a targeted manner according to demand, and the present invention does not impose any limitation on this.

[0070] The refrigerator 1 also includes a low-temperature and high-humidity thawing device 10, which is arranged inside the storage compartment. In order to ensure the normal use of the low-temperature and high-humidity thawing device 10 and avoid quality problems such as condensation, the compartment temperature of the storage compartment can be configured to -5°C to 40°C, such as 5°C, 10°C, 15°C, etc. A shelf can be provided in the storage compartment, and the low-temperature and high-humidity thawing device 10 is arranged on the shelf. Or the low-temperature and high-humidity thawing device 10 is arranged on the inner side of the door body 30 of the refrigerator 1, for example, it is placed on the bottle seat of the door body 30, or the low-temperature and high-humidity thawing device 10 is arranged on the outer side of the door body 30 of the refrigerator 1, the outer side of the box body 20 or the top of the box body 20, so that it can be used independently.

[0071] With the low-temperature and high-humidity thawing device 10 and the refrigerator 1 of this embodiment, when the flow-promoting component 110 blows the thawing airflow toward the object to be thawed through the air supply port 144, the thawing airflow can flow back to the flow-promoting component 110 from the return air port 145 through the drainage air duct 146 after exchanging heat with the object to be thawed. This is conducive to the smoothness of the flow of the thawing airflow, improves the heat exchange efficiency between the thawing airflow and the object to be thawed, and thus accelerates the thawing speed of the object to be thawed.

[0072] Furthermore, the internal humidity of the thawing chamber 143 can be increased by the humidifying component 130, thereby increasing the moisture content of the thawing airflow. During the heat exchange between the thawing airflow and the object to be thawed, the thawing airflow can also keep the surface of the object to be thawed moist, thereby reducing or avoiding the problem of drying out the object to be thawed due to the continuous blowing of the thawing airflow, which is beneficial to improving the thawing quality of the object to be thawed.
