Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The embodiment of the utility model firstly provides a low-temperature high-humidity thawing device 10, wherein the low-temperature high-humidity thawing device 10 is used for rapidly thawing objects to be thawed, the objects to be thawed are mainly meat to be thawed, the freezing temperature of the meat is low, and the temperature when the meat is taken out from the freezing device is about-18 ℃.

Fig. 1 is a structural view of a low temperature and high humidity thawing apparatus 10 according to an embodiment of the present utility model, fig. 2 is an exploded view of a thawing tank 140 and a thawing drawer 150 according to an embodiment of the present utility model, and fig. 3 is a sectional view of the low temperature and high humidity thawing apparatus 10 according to an embodiment of the present utility model, and referring to fig. 1 to 3, the low temperature and high humidity thawing apparatus 10 may include a thawing tank 140, a thawing drawer 150, and a flow-promoting assembly 110.

The thawing box 140 defines a forwardly opened thawing compartment 141, and the thawing drawer 150 is slidably disposed within the thawing compartment 141 through the forwardly opening. The flow-promoting assembly 110 is configured to controllably blow a defrost airflow into the defrost drawer 150 such that the temperature of the airflow blown by the defrost airflow into the defrost drawer 150 is between 5 ℃ and 50 ℃.

Because the air flow temperature of the defrosting air flow blown to the defrosting drawer 150 by the flow promoting assembly 110 is 5-50 ℃, when the object to be defrosted is placed in the defrosting drawer 150 for defrosting, the defrosting air flow can quickly exchange heat with the object to be defrosted, so that the defrosting speed of the object to be defrosted is improved, the problem of curing does not occur in the defrosting process, and the defrosting quality of the object to be defrosted is effectively ensured. The setting of the thawing drawer 150 can prevent the thawing water drop in the thawing process from reaching the thawing compartment 141, so that the complicated work of cleaning the thawing compartment 141 is omitted, and the use experience of a user is improved.

In some alternative embodiments, the flow-promoting assembly 110 may be an axial flow fan, the depth of the thawing compartment 141 being greater than the length of the thawing drawer 150, and there being room left behind the thawing compartment 141 when the thawing drawer 150 is fully advanced into the thawing compartment 141. The flow-promoting assembly 110 may be disposed behind the thawing compartment 141, and an air inlet 151 may be disposed at a position of the thawing drawer 150 opposite to the flow-promoting assembly 110. During thawing, the flow-promoting assembly 110 blows thawing air flow toward the object to be thawed through the air inlet 151.

Further, a return air duct 144 is formed between the defrosting drawer 150 and the flow promoting assembly 110, and defrosting air blown into the defrosting drawer 150 can flow back to the flow promoting assembly 110 through the return air duct 144. Therefore, the flow smoothness of the defrosting air flow can be improved, and the heat exchange speed of the defrosting air flow and the object to be defrosted can be increased. The unfreezing air flow which is not subjected to complete heat exchange can be blown to the object to be unfrozen again, so that the complete heat exchange of the unfreezing air flow is facilitated, and the unfreezing cost is reduced.

In some alternative embodiments, the side walls of the defrosting drawer 150 can be positioned lower than the top wall of the defrosting compartment 141, such that the top of the defrosting drawer 150 forms the return air duct 144, and the access opening at the top of the defrosting drawer 150 can serve as the return air opening 153 of the return air duct 144. During thawing, the thawing drawer 150 is fully pushed into the thawing compartment 141 and the thawing air flow blown by the flow-promoting assembly 110 to the thawing drawer 150 can enter the return air duct 144 through the return air inlet 153.

Further, the width of the thawing drawer 150 is smaller than the width of the thawing compartment 141, so that the two sides of the thawing drawer 150 also form the return air duct 144, and the side wall of the thawing drawer 150 is provided with a return air inlet 153 communicating with the return air duct 144. During thawing, a portion of the thawing air flow may also flow back to the flow-promoting assembly 110 from the return air duct 144 between the thawing drawer 150 and the sidewall of the thawing compartment 141 through the return air inlet 153, which is advantageous for further improving the smoothness of the thawing air flow circulation.

Ideally, most of the defrost air flow blown by the flow enhancing assembly 110 into the defrost drawer 150 will climb up after the front end of the defrost drawer 150 is blocked, then enter the upper return air duct 144 through the access opening, and then flow back into the flow enhancing assembly 110 from front to back along the return air duct 144. However, in practical applications, due to the influence of the flow-promoting assembly 110, a part of the thawing airflow may sink at the rear end of the thawing drawer 150 and re-enter the thawing drawer 150, resulting in poor circulation of the thawing airflow.

To solve the above problem, in this embodiment, an air guiding structure 145 is disposed at the rear end of the return air duct 144 above the defrosting drawer 150, and the air guiding structure 145 may include an air guiding bottom plate 145a and a plurality of air guiding side plates 145b. The air guide bottom plate 145a may be parallel to the top wall of the thawing compartment 141, disposed below the top wall of the thawing compartment 141 at intervals of a preset interval, and the plurality of air guide side plates 145b may be disposed between the air guide bottom plate 145a and the top wall of the thawing compartment 141 at intervals in a lateral direction of the thawing compartment 141, and connect the air guide bottom plate 145a and the top wall of the thawing compartment 141, each air guide side plate 145b extending in a depth direction of the thawing compartment 141, and an air guide gap 145c for a thawing air flow to pass through is formed between adjacent air guide side plates 145b.

Thus, when the defrosting air flow moves to the upper part of the rear end of the defrosting drawer 150, the air guide bottom plate 145a can support the defrosting air flow to prevent the defrosting air flow from sinking, and the air guide side plate 145b can guide the defrosting air flow to quickly flow back to the flow promoting assembly 110 from the air guide gap 145c, so that the circulation smoothness of the defrosting air flow is ensured.

In some alternative embodiments, the rear of the thawing compartment 141 may be provided with a mounting frame 142, which mounting frame 142 may be a freestanding structure, or a unitary structure with the thawing tank 140. The mounting frame 142 is provided with an air supply opening 142a, the flow promoting assembly 110 can be arranged in the air supply opening 142a, and when the thawing drawer 150 is completely pushed into the thawing compartment 141, the rear end of the thawing drawer 150 is mutually abutted with the front end of the mounting frame 142, and the flow promoting assembly 110 just faces the air inlet 151 of the thawing drawer 150.

The air guiding structure 145 may be integrally formed with the mounting frame 142, and the air guiding gap 145c may be in communication with a space behind the flow promoting assembly 110. Vents 142c are formed on both sides of the mounting frame 142, and the defrosting air flow flowing back from the air return port 153 of the defrosting drawer 150 can enter the space behind the flow promotion assembly 110 through the vents 142c, and then is blown back to the defrosting drawer 150 by the flow promotion assembly 110.

The wind speed of the flow promoting assembly 110 may 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 appreciated that the wind speed of the proximal end of the flow promoting assembly 110 is larger, and the wind speed of the distal end is smaller, so that in practical application, the wind speed of the flow promoting assembly 110 and the distance between the flow promoting assembly 110 and the object to be defrosted should be reasonably configured, so that the defrosting air flow blown to the object to be defrosted is ensured to have enough blowing force, and thus, heat exchange with the object to be defrosted is effectively performed.

Of course, the above examples are merely illustrative, and those skilled in the art should easily develop and change the low temperature and high humidity thawing apparatus 10 according to the present embodiment, for example, using a centrifugal fan and matching with a specific air duct structure, and these expansions should fall within the scope of the present utility model.

It should be noted that, the flow promoting assembly 110 of the present utility model may or may not have a heating function, and the flow promoting assembly is shown in the drawings as a general axial fan without a heating function.

In some alternative embodiments, the low temperature and high humidity thawing apparatus 10 may further include a heating assembly 120, and the heating assembly 120 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 18-30 ℃. For example, 18℃at 20℃at 25℃at 28℃at 30℃and the like. It will be appreciated that since the internal temperature of the defrosting compartment 141 is relatively high, the temperature of the defrosting air stream when it is blown to the object to be defrosted is also high. Therefore, the heat exchange quantity of the defrosting airflow and the object to be defrosted can be increased, and the heat exchange efficiency is improved.

In some preferred embodiments, the heating assembly 120 may also be used to directly heat the thawing air flow, in which way the heated thawing air flow can be directly blown to the object to be thawed by the flow promoting assembly 110, which is beneficial to reducing heat loss, and the temperature of the heated air flow is relatively easy to control.

Specifically, the heating assembly 120 may include heating pipes 121, and the heating pipes 121 are disposed at a front side (an air outlet side) or a rear side (an air inlet side) of the flow promoting assembly 110 at predetermined intervals, which are front sides in the drawing. The heat generated by the heating pipe 121 can be directly carried to the object to be thawed by the defrosting air flow, which is beneficial to reducing heat loss and improving heating efficiency of the heating assembly 120.

The heating pipe 121 may be bent into a polygonal ring shape or a coiled shape, thereby increasing the contact area with the defrosting air flow, improving heating efficiency and heating uniformity, reducing the blocking effect on the defrosting air flow, and maintaining the flow smoothness of the defrosting air flow.

The air supply port 142a may have a certain length in the front-rear direction of the thawing compartment 141, and the heating pipe 121 may be fixed to the inner circumference of the air supply port 142 a. The power of the heating pipe 121 may be 10W to 200W, for example, 10W, 20W, 50W, 80W, 100W, 200W, etc., specifically, the power may be selected in a targeted manner according to practical requirements, so as to ensure that the temperature of the heated thawing airflow can meet the thawing requirements.

In some alternative embodiments, the heating assembly 120 may also include a heating plate that covers the front or rear side of the flow-promoting assembly 110 and has grill holes for the flow of defrost air. The contact area between the air flow and the defrosting air flow can be increased, and the heating efficiency and the heating uniformity are improved.

It should be noted that, the connection mode between the flow promoting assembly 110 and the power supply and the connection mode between the heating assembly 120 and the power supply may be varied, and those skilled in the art can arrange the flow promoting assembly and the heating assembly by themselves without any need of inventive arrangements.

In some alternative embodiments, the low-temperature and high-humidity thawing apparatus 10 may further include a humidifying assembly 130, the humidifying assembly 130 may include a water storage box 131 and an atomizing head 132, the water storage box 131 is used for storing humidifying water, the atomizing head 132 is communicated with the inside of the water storage box 131 and is used for converting the humidifying water into humidifying air flow and supplying the humidifying air flow into the thawing drawer 150, so that the internal humidity of the thawing drawer 150 is increased, the surface of the to-be-thawed object is kept moist, the air drying degree of the to-be-thawed object in the thawing process is reduced, and the thawing quality of the to-be-thawed object is improved.

The water storage box 131 may be fixed on the thawing tank 140, the atomizing head 132 may be fixed on the water storage box 131, and the atomizing head 132 may be selected as a microporous atomizing head 132 with a working frequency of 120KHz or less, or a real-hole atomizing head 132 with a working frequency of more than 1.7 MHz. The atomization amount of the atomizing head 132 can be 20ml/h to 60ml/h, the atomization amount in the range is more suitable, and the working energy consumption of the atomizing head 132 can be saved on the premise of meeting the thawing requirement.

In some examples, referring to fig. 1 and 5, the water storage tank 131 may be disposed at the top of the thawing tank 140. The water storage box 131 is provided with a water filling port, and a cover plate 131a is arranged at the water filling port. The cover plate 131a may be opened by tilting or rotating or by pulling, etc., and there are various specific opening modes, and the present utility model is not limited thereto. The water filling port is exposed by opening the cover plate 131a, so that a user can conveniently supplement the humidifying water into the water storage box 131 through the water filling port. When the cover plate 131a is closed, the cover plate 131a can shield the water filling port to prevent foreign matters from entering the water storage box 131.

Further, the side wall of the water storage tank 131 may be provided with an observation window 131b, and the observation window 131b is used for a user to view the water level of the humidifying water in the water storage tank 131. The observation window 131b may be made of transparent material and extend 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 cover plate 131a can be opened in time to supplement the humidification water into the water storage box 131.

In this embodiment, the atomizing head 132 is located at the rear of the thawing compartment 141, the water storage box 131 is located at the top front end of the thawing tank 140, and a connection pipe 133 is provided between the atomizing head 132 and the water storage box 131. The connection pipe 133 may be penetrated in the thawing tank 140, and may extend gradually obliquely downward from one end of the water storage tank 131 to one end of the atomizing head 132. Thus, the humidification water in the water storage case 131 can flow to the atomizing head 132 quickly. The bottom wall of the water storage tank 131 may be disposed higher than the atomizing head 132 so that all the humidification water in the water storage tank 131 can flow to the atomizing head 132.

Further, a mounting groove is provided at the top front end of the thawing tank 140, and the water storage box 131 is fitted in the mounting groove. An observation port is provided at a position where the front end surface of the thawing tank 140 faces the observation window 131 b. When the user pulls the defrosting drawer 150 outward, the water level of the humidifying water is observed from the observation port.

In some alternative embodiments, the water storage tank 131 may also be provided at the top rear end of the thawing tank 140, with the atomizing head 132 directly fixed to the water storage tank 131 and extending into the thawing compartment 141. Or, the water storage box 131 can also be slidably inserted into the thawing tank 140, the water storage box 131 is provided with a water outlet of a spring switch, and after the water storage box 131 is inserted into place, the atomizing head 132 is also inserted into place with the water outlet, so that the atomizing head 132 is communicated with the inside of the water storage box 131.

In practical applications, it is found that even if the internal humidity of the thawing compartment 141 is high, the surface of the object to be thawed still has a problem of air-drying to some extent due to the blowing action of the thawing airflow. For this purpose, the atomizing head 132 is disposed toward the air supply path between the flow promoting assembly 110 and the object to be defrosted in this embodiment. Therefore, the humidifying airflow and the defrosting airflow can be mixed in advance, so that the moisture content of the defrosting airflow is increased, and the surface of the object to be defrosted can be kept moist in the process of heat exchange between the defrosting airflow and the object to be defrosted.

In some examples, the atomizing head 132 may also be disposed rearward of the thawing compartment 141. For example, the mounting frame 142 has a humidification port 142b provided on the outer periphery of the air supply port 142a, the atomizing head 132 is mounted in the humidification port 142b, a humidity inlet 152 is provided at a position of the defrosting drawer 150 facing the atomizing head 132, and the atomizing head 132 blows a humidified air flow into the defrosting drawer 150 through the humidity inlet 152.

The atomizing head 132 may be positioned above the flow promoting assembly 110 and extend progressively obliquely downward from back to 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 beneficial to reducing the loss of the humidified airflow in the flowing process and improving the utilization rate of the humidified airflow.

The mounting frame 142 may be configured according to actual needs such that its front shape is adapted to the rear shape of the thawing drawer 150. When the thawing drawer 150 is completely pushed into the thawing box 140, the rear end of the thawing drawer 150 and the front end of the mounting frame 142 are abutted against each other, the flow promoting assembly 110 can just face the air inlet 151 of the thawing drawer 150, and the atomizing head 132 can just face the moisture inlet 152 of the thawing drawer 150.

In some alternative embodiments, the low temperature and high humidity thawing apparatus 10 can further include a tray 160, referring to fig. 6, the tray 160 is disposed within the thawing drawer 150 for holding the thawed objects. In this way, the defrosting water generated in the defrosting process can be stored in the defrosting drawer 150, so that the defrosting water is prevented from dripping into the defrosting compartment 141, and pollution to the defrosting compartment 141 is avoided. Compared with the thawing compartment 141, the thawing drawer 150 can be pulled out and carried to the sink for washing by a user more conveniently, thereby improving the convenience of the user.

The tray 160 may be provided with a ventilation groove that may extend in the front-rear direction of the thawing compartment 141, the ventilation groove being configured to allow at least a portion of the thawing air flow to pass through the bottom of the thawed object during the blowing of the thawing air flow by the flow-promoting assembly 110. Therefore, under the action of the ventilation groove, the defrosting air flow can be in contact heat exchange with the bottom of the object to be defrosted, so that the object to be defrosted is defrosted more uniformly.

In an alternative embodiment, referring to fig. 7, the tray 160 may include a first bottom plate 161, the first bottom plate 161 being curved in a wave shape, with ventilation grooves formed between adjacent two peaks. The tray 160 has a simple structure and is easy to machine and shape.

In another alternative embodiment, referring to fig. 8, the tray 160 may include a second bottom plate 162, and at least two first support bars 163 are provided at intervals on an upper surface of the second bottom plate 162, with ventilation grooves formed between adjacent two first support bars 163.

In some alternative embodiments, the second base plate 162 may be designed to be thicker, so that it is also possible to provide a plurality of ventilation grooves spaced apart on the upper surface of the second base plate 162.

At least two second supporting bars 164 are spaced apart from the lower surface of the second base plate 162. In the process of blowing the defrosting air flow towards the object to be defrosted, part of the defrosting air flow can pass through between the two second supporting bars 164, which is beneficial to reducing the blocking effect on the defrosting air flow and improving the flow smoothness of the defrosting air flow.

Besides, the defrosting water generated by the object to be defrosted can flow out from the two ends of the ventilation groove, so that the defrosting water can be prevented from being soaked in the object to be defrosted, the defrosting quality of the object to be defrosted is improved, and the edible taste after cooking is kept.

In some alternative embodiments, the heating assembly 120 may further include a heating wire 122, the heating wire 122 being disposed at the bottom of the tray 160 for applying heat to the object to be thawed. Therefore, the bottom defrosting speed of the object to be defrosted can be further improved, so that the object to be defrosted is completely defrosted in a short time.

Further, the heating assembly 120 may further include a heat transfer plate 123, the heat transfer plate 123 being disposed between the heating wire 122 and the tray 160. The heating wire 122 may be bent into a serpentine shape or wound around a disk shape, and the heat transfer plate 123 may increase a heat transfer area of the heating wire 122, thereby making the heating wire 122 more uniformly apply heat to the tray 160.

The heat transfer plate 123 may be an aluminum heat transfer plate 123. The aluminum heat transfer plate 123 has a high heat transfer coefficient, and has good heat conduction and heat dissipation properties, so that heat generated by the heating wire 122 can be transferred to the tray 160 more efficiently.
