Description

Technical Field

[0001] The present invention relates to the technical field of food thawing, and in particular to a refrigerator and a low-temperature and high-humidity thawing device thereof. Background Art

[0002] At present, the thawing method of food is usually natural thawing, which means placing the frozen food in a room temperature environment and relying on the ambient temperature to thaw. However, this thawing method has the problems of slow thawing speed and incomplete thawing. Since the food is exposed to the air, it is easy to be contaminated by bacteria and rot.

[0003] In order to improve the thawing speed and thawing quality, many thawing methods have emerged in the prior art, such as electric heating thawing, hot water thawing, running water thawing, air thawing, and refrigerated thawing. However, the above thawing methods all have certain disadvantages and thus produce certain adverse consequences, such as: local ripening caused by uneven heating, loss of juice caused by water immersion, and poor user experience caused by long thawing time. Summary of the invention

[0004] An object of the first aspect of the present invention is to increase the thawing speed of the object to be thawed and prevent the object to be thawed from being cooked during the thawing process.

[0005] A further object of the first aspect of the present invention is to improve the flow smoothness of the thawing air flow.

[0006] A second aspect of the present invention aims to provide a refrigerator.

[0007] In particular, according to a first aspect of the present invention, the present invention provides a low-temperature and high-humidity thawing device, comprising:

[0008] a thawing box defining a forwardly opening thawing compartment;

[0009] A thawing drawer is disposed in the thawing compartment in a push-pull manner through the front opening; and

[0010] The flow promotion component is configured to blow a thawing airflow into the thawing drawer in a controlled manner so that the airflow temperature of the thawing airflow blown to the thawing drawer is 5°C to 50°C.

[0011] Optionally, a return air duct is formed between the thawing drawer and the flow promotion component, and the thawing air flow blown into the thawing drawer flows back to the flow promotion component through the return air duct.

[0012] Optionally, the flow promotion component is arranged behind the thawing drawer, and an air inlet is arranged at a relative position between the thawing drawer and the flow promotion component.

[0013] Optionally, the return air duct is formed above the thawing drawer, and the access opening at the top of the thawing drawer serves as the return air opening of the return air duct.

[0014] Optionally, the side wall of the thawing drawer is lower than the top wall of the thawing compartment, so that the return air duct is formed above the thawing drawer.

[0015] Optionally, an air guide structure is provided at the rear end of the return air duct, and the air guide structure includes an air guide bottom plate and a plurality of air guide side plates arranged on the air guide bottom plate, and an air guide gap is formed between adjacent air guide side plates for the thawing airflow to pass through.

[0016] Optionally, the return air duct is formed on at least one side of the thawing drawer, and a return air port of the return air duct is provided on a side wall of the thawing drawer.

[0017] Optionally, the low-temperature and high-humidity thawing device further comprises:

[0018] The heating component is arranged in the thawing chamber and is used for adjusting the internal temperature of the thawing chamber.

[0019] Optionally, the heating component is further arranged on the air inlet side or the air outlet side of the flow promotion component to adjust the airflow temperature of the thawing airflow.

[0020] According to a second aspect of the present invention, the present invention provides a refrigerator comprising any one of the low-temperature and high-humidity thawing devices described above.

[0021] In the low-temperature and high-humidity thawing device of the present invention, since the airflow temperature of the thawing airflow blown by the flow-promoting component to the thawing drawer is 5°C to 50°C, when the object to be thawed is placed in the thawing drawer for thawing, the thawing airflow can quickly exchange heat with the object to be thawed, thereby increasing the thawing speed of the object to be thawed, and there will be no ripening problem during the thawing process, effectively ensuring the thawing quality of the object to be thawed. The provision of the thawing drawer can prevent the thawing water from dripping into the thawing chamber during the thawing process, eliminating the tedious work of cleaning the thawing chamber later, which is conducive to improving the user experience.

[0022] Furthermore, in the low-temperature and high-humidity thawing device of the present invention, since a return air duct is formed between the thawing drawer and the flow-promoting component, the thawing airflow blown to the thawing chamber can flow back to the flow-promoting component through the return air duct, thereby improving the flow smoothness of the thawing airflow and accelerating the heat exchange rate between the thawing airflow and the object to be thawed. The thawing airflow that has not been completely heat-exchanged can also be blown to the object to be thawed again, which is conducive to achieving complete heat exchange of the thawing airflow, thereby reducing the thawing cost.

DETAILED DESCRIPTION

[0032] 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.

[0033] The embodiment of the present invention first provides a low-temperature and high-humidity thawing device 10, which is used to quickly thaw the objects to be thawed. The objects to be thawed are mainly meats to be thawed. The freezing temperature of meat is relatively low, and the temperature when taken out of the freezing device is about -18°C.

[0034] 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 an exploded view of a thawing box 140 and a thawing drawer 150 according to an embodiment of the present invention, Figure 3 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 Figures 1 to 3 The low-temperature and high-humidity thawing device 10 may include a thawing box 140, a thawing drawer 150 and a flow promotion component 110.

[0035] The thawing box 140 defines a thawing compartment 141 with a forward opening, and the thawing drawer 150 is push-pullably arranged in the thawing compartment 141 through the forward opening. The flow promotion component 110 is configured to controllably blow thawing airflow into the thawing drawer 150, so that the airflow temperature of the thawing airflow blown to the thawing drawer 150 is 5°C to 50°C.

[0036] Since the air flow temperature of the thawing airflow blown by the flow promotion component 110 to the thawing drawer 150 is 5°C to 50°C, when the object to be thawed is placed in the thawing drawer 150 for thawing, the thawing airflow can quickly exchange heat with the object to be thawed, thereby increasing the thawing speed of the object to be thawed, and there will be no ripening problem during the thawing process, effectively ensuring the thawing quality of the object to be thawed. The setting of the thawing drawer 150 can prevent the thawing water from dripping into the thawing chamber 141 during the thawing process, eliminating the tedious work of cleaning the thawing chamber 141 later, which is conducive to improving the user experience.

[0037] In some optional embodiments, the flow promotion component 110 may be an axial flow fan, the depth of the thawing chamber 141 is greater than the length of the thawing drawer 150, and when the thawing drawer 150 is fully pushed into the thawing chamber 141, there is still remaining space behind the thawing chamber 141. The flow promotion component 110 may be arranged behind the thawing chamber 141, and an air inlet 151 is arranged at a relative position between the thawing drawer 150 and the flow promotion component 110. During the thawing process, the flow promotion component 110 blows the thawing airflow toward the object to be thawed through the air inlet 151.

[0038] Furthermore, a return air duct 144 is formed between the thawing drawer 150 and the flow promotion component 110, and the thawing airflow blown into the thawing drawer 150 can flow back to the flow promotion component 110 through the return air duct 144. In this way, the flow smoothness of the thawing airflow can be improved, and the heat exchange rate between the thawing airflow and the object to be thawed can be accelerated. The thawing airflow that has not been completely heat exchanged can also be blown to the object to be thawed again, which is conducive to achieving complete heat exchange of the thawing airflow, thereby reducing the thawing cost.

[0039] In some optional embodiments, the side wall of the thawing drawer 150 can be arranged lower than the top wall of the thawing chamber 141, so that a return air duct 144 is formed above the thawing drawer 150, and the access opening at the top of the thawing drawer 150 can serve as a return air port 153 of the return air duct 144. During the thawing process, the thawing drawer 150 is completely pushed into the thawing chamber 141, and the thawing airflow blown to the thawing drawer 150 by the flow promotion component 110 can enter the return air duct 144 through the return air port 153.

[0040] Furthermore, the width of the thawing drawer 150 is smaller than the width of the thawing chamber 141, so that the return air duct 144 is also formed on both sides of the thawing drawer 150, and a return air port 153 connected to the return air duct 144 is opened on the side wall of the thawing drawer 150. During the thawing process, part of the thawing airflow can also flow back to the flow promotion component 110 from the return air duct 144 between the thawing drawer 150 and the side wall of the thawing chamber 141 through the return air port 153, which is conducive to further improving the smoothness of the circulation of the thawing airflow.

[0041] In an ideal state, most of the thawing airflow blown by the flow promotion component 110 to the thawing drawer 150 will be blocked at the front end of the thawing drawer 150 and then rise upward, and then enter the return air duct 144 above through the access port, and then flow back to the flow promotion component 110 from front to back along the return air duct 144. However, in actual applications, due to the influence of the flow promotion component 110, part of the thawing airflow will sink at the rear end of the thawing drawer 150 and re-enter the thawing drawer 150, resulting in poor circulation effect of the thawing airflow.

[0042] To solve the above problems, in this embodiment, an air guide structure 145 is provided at the rear end of the return air duct 144 above the thawing drawer 150. The air guide structure 145 may include an air guide bottom plate 145a and a plurality of air guide side plates 145b. The air guide bottom plate 145a may be parallel to the top wall of the thawing chamber 141 and may be arranged below the top wall of the thawing chamber 141 at a predetermined interval. The plurality of air guide side plates 145b may be arranged between the air guide bottom plate 145a and the top wall of the thawing chamber 141 along the lateral direction of the thawing chamber 141 and connect the air guide bottom plate 145a and the top wall of the thawing chamber 141. Each air guide side plate 145b extends along the depth direction of the thawing chamber 141. An air guide gap 145c for the thawing airflow to pass through is formed between adjacent air guide side plates 145b.

[0043] In this way, when the thawing airflow moves to the upper rear end of the thawing drawer 150, the air guide bottom plate 145a can support the thawing airflow to prevent the thawing airflow from sinking, and the air guide side plate 145b can guide the thawing airflow to flow quickly back to the flow promotion component 110 from the air guide gap 145c, thereby ensuring the smooth circulation of the thawing airflow.

[0044] In some optional embodiments, a mounting frame 142 may be provided at the rear of the thawing chamber 141, and the mounting frame 142 may be an independent structure, or an integrated structure with the thawing box 140. An air supply port 142a is provided on the mounting frame 142, and the flow promotion component 110 may be provided in the air supply port 142a. When the thawing drawer 150 is fully pushed into the thawing chamber 141, the rear end of the thawing drawer 150 and the front end of the mounting frame 142 abut against each other, and the flow promotion component 110 is just opposite to the air inlet 151 of the thawing drawer 150.

[0045] The air guide structure 145 can be an integrated structure with the installation frame 142, and the air guide gap 145c is connected to the space behind the flow promotion component 110. Ventilation holes 142c are provided on both sides of the installation frame 142, and the thawing airflow flowing back from the return air port 153 of the thawing drawer 150 can enter the space behind the flow promotion component 110 through the ventilation holes 142c, and then be blown back to the thawing drawer 150 by the flow promotion component 110.

[0046] The wind speed of the flow promotion component 110 can be set to 0.2m / s to 3m / s. For example, 0.2m / s, 0.5m / s, 0.8m / s, 1.0m / s, 1.5m / s, 1.8m / s, 2.0m / s, 2.5m / s, 3m / s, etc. It can be understood that 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 distance between the flow promotion component 110 and the object to be thawed should be reasonably configured to ensure that the thawing airflow blown to the object to be thawed has sufficient blowing force, so as to effectively exchange heat with the object to be thawed.

[0047] Of course, the above examples are merely illustrative. Based on the understanding of these embodiments, technical personnel in this field should be able to easily expand and transform the low-temperature and high-humidity thawing device 10 of this embodiment, such as using a centrifugal fan in combination with a specific air duct structure. These expansions should all fall within the scope of protection of the present invention.

[0048] It should be noted that the flow promotion component 110 of the present invention may or may not have a heating function. The one shown in the drawings is only an ordinary axial flow fan without a heating function.

[0049] In some optional embodiments, the low temperature and high humidity thawing device 10 may further include a heating assembly 120, which may be disposed in the thawing compartment 141, for adjusting the internal temperature of the thawing compartment 141, and controlling the internal temperature of the thawing compartment 141 to be between 18°C ​​and 30°C. For example, 18°C, 20°C, 25°C, 28°C, 30°C, etc. It is understood that since the internal temperature of the thawing compartment 141 is relatively high, the airflow temperature when the thawing airflow is blown to the object to be thawed is also high. This can increase the heat exchange between the thawing airflow and the object to be thawed, and improve the heat exchange efficiency.

[0050] In some preferred embodiments, the heating component 120 can also be used to directly heat the thawing airflow. In this way, the heated thawing airflow can be directly blown to the object to be thawed by the flow-promoting component 110, which is beneficial to reduce heat loss, and the temperature of the heated airflow is relatively easy to control.

[0051] Specifically, the heating assembly 120 may include a heating tube 121, which is arranged at a preset interval on the front side (air outlet side) or the rear side (air inlet side) of the flow promotion assembly 110, and the front side is shown in the figure. In this way, the heat generated by the heating tube 121 can be directly carried by the thawing airflow to the object to be thawed, which is conducive to reducing heat loss and improving the heating efficiency of the heating assembly 120.

[0052] The heating tube 121 can be bent into a polygonal ring or a coil, thereby increasing its contact area with the thawing airflow, improving heating efficiency and heating uniformity, while reducing obstruction to the thawing airflow and maintaining smooth flow of the thawing airflow.

[0053] The air outlet 142a may have a certain length in the front-to-back direction of the thawing chamber 141, and the heating pipe 121 may be fixed to the inner periphery of the air outlet 142a. The power of the heating pipe 121 may be 10W to 200W, such as 10W, 20W, 50W, 80W, 100W, 200W, etc., and may be specifically selected according to actual needs, in order to ensure that the temperature of the thawing airflow after heating can meet the thawing requirements.

[0054] In some alternative embodiments, the heating assembly 120 may also include a heating plate, which is buckled on the front side or the rear side of the flow promoting assembly 110, and the heating plate is provided with grille holes for the thawing airflow to pass through. This method can also increase the contact area with the thawing airflow, improve the heating efficiency and the uniformity of heating.

[0055] It should be noted that there may be various ways to connect the flow promotion component 110 and the power supply, and the heating component 120 and the power supply, and those skilled in the art may arrange them by themselves without any creativity.

[0056] In some optional embodiments, the low-temperature and high-humidity thawing device 10 may further include a humidifying component 130. The humidifying component 130 may include a water storage box 131 and an atomizing head 132. The water storage box 131 is used to store humidification water. The atomizing head 132 is connected to the interior of the water storage box 131 and is used to convert the humidification water into a humidified airflow and supply it to the thawing drawer 150, thereby increasing the internal humidity of the thawing drawer 150, keeping the surface of the to-be-thawed object moist, and reducing the degree of air drying of the to-be-thawed object during the thawing process, which is beneficial to improving the thawing quality of the to-be-thawed object.

[0057] The water storage box 131 can be fixed on the thawing box 140, and the atomizing head 132 can be fixed on the water storage box 131. The atomizing head 132 can be selected as a micro-pore atomizing head 132 with an operating frequency less than or equal to 120KHz, or a solid-pore atomizing head 132 with an operating frequency greater than 1.7MHz. The atomization amount of the atomizing head 132 can be 20ml / h to 60ml / h. The atomization amount within this range is more suitable, and the working energy consumption of the atomizing head 132 can be saved while meeting the thawing requirements.

[0058] In some examples, reference Figure 1 and Figure 5 The water storage box 131 can be arranged on the top of the thawing box 140. The water storage box 131 is provided with a water inlet, and a cover plate 131a is provided at the water inlet. The cover plate 131a can be flipped open, rotated open, pulled open, etc. There are various specific opening methods, and the present invention does not limit this. By opening the cover plate 131a to reveal the water inlet, the user can more conveniently add humidification water to the water storage box 131 through the water inlet. When the cover plate 131a is closed, the cover plate 131a can cover the water inlet to prevent foreign matter from entering the water storage box 131.

[0059] Furthermore, the side wall of the water storage box 131 may be provided with an observation window 131b, and the observation window 131b is used for the user to see the water level of the humidification water in the water storage box 131. The observation window 131b may be made of a transparent material, and extends from top to bottom along the height direction of the water storage box 131 to the bottom of the water storage box 131. When the user finds that the humidification water in the water storage box 131 is insufficient through the observation window 131b, the user can open the cover plate 131a in time to add humidification water to the water storage box 131.

[0060] In this embodiment, the atomizing head 132 is located behind the thawing chamber 141, the water storage box 131 is located at the top front end of the thawing box 140, and a connecting pipe 133 is provided between the atomizing head 132 and the water storage box 131. The connecting pipe 133 can be inserted into the thawing box 140, and it can gradually extend downward from one end of the water storage box 131 to one end of the atomizing head 132. In this way, it is conducive to the humidification water in the water storage box 131 to flow quickly to the atomizing head 132. The bottom wall of the water storage box 131 can also be set higher than the atomizing head 132, so that the humidification water in the water storage box 131 can all flow to the atomizing head 132.

[0061] Furthermore, a mounting groove is provided at the top front end of the thawing box 140, and the water storage box 131 is embedded in the mounting groove. An observation port is provided at a position opposite to the observation window 131b on the front face of the thawing box 140. When the user pulls out the thawing drawer 150, the water level of the humidification water can be observed from the observation port.

[0062] In some alternative embodiments, the water storage box 131 can also be arranged at the top rear end of the thawing box 140, and the atomizing head 132 is directly fixed to the water storage box 131 and extends into the thawing chamber 141. Alternatively, the water storage box 131 can also be slidably plugged with the thawing box 140, and the water storage box 131 has a water outlet with a spring switch. When the water storage box 131 is plugged into place, the atomizing head 132 is also plugged into place with the water outlet, so that the atomizing head 132 is connected to the inside of the water storage box 131.

[0063] In actual application, it is found that even if the internal humidity of the thawing chamber 141 is relatively high, the surface of the object to be thawed will still be dried to a certain extent due to the blowing of the thawing airflow. For this reason, in this embodiment, the atomizing head 132 is arranged toward the air supply path between the flow-promoting component 110 and the object to be thawed. In this way, the humidified airflow can be mixed with the thawing airflow in advance, thereby increasing the moisture content of the thawing airflow, so that the surface of the object to be thawed can be kept moist during the heat exchange between the thawing airflow and the object to be thawed.

[0064] In some examples, the atomizing head 132 may also be arranged behind the thawing chamber 141. For example, the mounting frame 142 is provided with a humidifying port 142b at the periphery of the air supply port 142a, the atomizing head 132 is installed in the humidifying port 142b, and the thawing drawer 150 is provided with a moisture inlet 152 at a position opposite to the atomizing head 132, and the atomizing head 132 blows a humidified airflow toward the thawing drawer 150 through the moisture inlet 152.

[0065] The atomizing head 132 can be located above the flow promoting assembly 110 and gradually extend downward from the back to the front. In this way, the humidified airflow generated by the atomizing head 132 can be mixed with the thawing airflow in the thawing drawer 150, which is conducive to reducing the loss of the humidified airflow during the flow process and improving the utilization rate of the humidified airflow.

[0066] The mounting frame 142 can be configured according to actual needs so that its front end shape matches the rear end shape of the thawing drawer 150. When the thawing drawer 150 is fully pushed into the thawing box 140, the rear end of the thawing drawer 150 and the front end of the mounting frame 142 abut against each other, the flow-promoting component 110 can be exactly opposite to the air inlet 151 of the thawing drawer 150, and the atomizing head 132 can be exactly opposite to the moisture inlet 152 of the thawing drawer 150.

[0067] In some optional embodiments, the thawing drawer 150 is provided with components such as a fence basket or a tray so that the bottom of the object to be thawed can also come into contact with the thawing airflow. Alternatively, the object to be thawed can be suspended in the thawing drawer 150. In this way, during the thawing process, the periphery of the object to be thawed can effectively come into contact with the thawing airflow, which is beneficial to improve the utilization rate of the thawing airflow, accelerate the thawing speed, and improve the thawing quality.

[0068] The present invention also provides a refrigerator 1, Figure 6 is a structural diagram of a refrigerator 1 according to an embodiment of the present invention, referring to Figure 6 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.

[0069] 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.
