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.

An embodiment of the present utility model firstly provides a low temperature and high humidity thawing apparatus 10, and fig. 1 is a block diagram of the low temperature and high humidity thawing apparatus 10 according to an embodiment of the present utility model, and referring to fig. 1, the low temperature and high humidity thawing apparatus 10 may include a thawing tank 140, a thawing drawer 150, and a water storage box 131.

Fig. 2 is an exploded view of the thawing box 140 and the thawing drawer 150 according to an embodiment of the present utility model, and referring to fig. 2, the thawing box 140 defines a thawing compartment 141 opened forward, the thawing drawer 150 is slidably provided in the thawing compartment 141, and a thawing to be thawed may be placed in the thawing drawer 150. The water storage box 131 is disposed on the thawing box 140 for supplying humidification water to the thawing drawer 150, thereby increasing the internal humidity of the thawing drawer 150, keeping the surface of the object to be thawed moist, and reducing the air-drying degree of the object to be thawed in the thawing process, which is advantageous for improving the thawing quality of the object to be thawed.

In some alternative embodiments, the low temperature, high humidity thawing device 10 further comprises an atomizing head 132, the atomizing head 132 being in communication with the interior of the water storage tank 131, configured to controllably convert the humidifying water within the water storage tank 131 into a humidified air stream, and to supply the humidified air stream to the thawing drawer 150. The atomization effect of the atomizing head 132 can rapidly improve the internal humidity of the thawing drawer 150, and can better maintain the surface humidity of the object to be thawed.

The atomizing head 132 may be selected to be a micro-porous atomizing head 132 having an operating frequency of 120KHz or less, or a real-porous atomizing head 132 having an operating frequency of greater 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.

A flow-promoting assembly 110 may be disposed within the thawing compartment 141, the flow-promoting assembly 110 being configured to controllably blow a thawing air flow toward the thawed objects. When the defrosting airflow blows to the object to be defrosted, heat exchange can be carried out between the defrosting airflow and the object to be defrosted, compared with natural defrosting, the defrosting speed of the object to be defrosted can be remarkably improved, the waiting time of a user is shortened, and better use experience is given to the user.

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 length of the thawing compartment 141 may be greater than the length of the thawing drawer 150, leaving room behind the thawing compartment 141 for placement of the flow-promoting assembly 110 after the thawing drawer 150 is fully advanced into the thawing compartment 141.

Specifically, a mounting frame 142 is disposed at the rear of the thawing compartment 141, an air supply port 142a is provided on the mounting frame 142, and the flow promoting assembly 110 is mounted in the air supply port 142 a. The thawing drawer 150 is provided with an air inlet 151 at a position opposite to the flow promoting assembly 110, and the flow promoting assembly 110 blows thawing air flow toward the to-be-thawed objects in the thawing drawer 150 through the air inlet 151.

The flow promoting assembly 110 may be an axial flow fan, and the wind speed thereof 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.

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.

Although the flow promoting assembly 110 is shown as an axial fan and blows the defrost air directly into the defrost drawer 150, it is within the scope of the present utility model to replace the axial fan with a centrifugal fan and blow the defrost air to the defrost drawer 150 with a specific air duct structure by a person skilled in the art without departing from the spirit and the essence of the present utility model.

The thawing compartment 141 may further be provided therein with a heating unit 120, and the heating unit 120 is used to adjust the internal temperature of the thawing compartment 141 such that the internal temperature of the thawing compartment 141 is controlled to 18-30 ℃. For example, 18℃at 20℃at 25℃at 28℃at 30℃and the like. It can be appreciated that, because the internal temperature of the thawing compartment 141 is relatively high, the air flow temperature of the thawing air flow blown to the object to be thawed by the flow promoting assembly 110 is also high, so that the thawing air flow can exchange heat with the object to be thawed sufficiently, the heat exchange amount between the thawing air flow and the object to be thawed is increased, and the heat exchange efficiency is improved.

In some preferred embodiments, the heating assembly 120 may also be used to directly heat the defrosting air flow, in which way the air flow temperature after the defrosting air flow is heated can be controlled accurately with ease.

Specifically, the heating assembly 120 may include heating pipes 121, and the heating pipes 121 are disposed at a front side or a rear side of the flow promoting assembly 110, which is a front side in the drawing, at predetermined intervals. 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 the actual thawing process, it is found that the rear end (the end adjacent to the flow promoting assembly 110) of the object to be thawed is continuously subjected to the thawing airflow, while the front end is only subjected to a small amount of thawing airflow, so that front and rear thawing is uneven, the rear half part may be completely thawed, and the front half part is still in a frozen state, so that the thawing efficiency is low, and energy conservation and consumption reduction are not facilitated.

For this purpose, a return air duct 144 is provided between the top wall of the thawing compartment 141 and the thawing drawer 150, and the air flow blown into the thawing drawer 150 by the flow promoting assembly 110 flows back to the flow promoting assembly 110 through the return air duct 144. That is, the defrost airflow may circulate through defrost drawer 150. The method is favorable for improving the flow smoothness of the defrosting air flow, can reduce the loss of wind speed, humidity, temperature and the like of the defrosting air flow in the flowing process, and can also have certain temperature and humidity for recycling the defrosting air flow flowing through the object to be defrosted.

Referring to fig. 3 and 4, in the embodiment of the present utility model shown in the drawings, both side walls of the thawing drawer 150 are lower than the top wall of the thawing compartment 141, so that the above-described return air duct 144 is formed between the top wall of the thawing compartment 141 and the thawing drawer 150. When the flow-enhancing assembly 110 blows air toward the interior of the defrost drawer 150, the air flow within the defrost drawer 150 may be forced upward and back into the flow-enhancing assembly 110 from the rear side of the flow-enhancing assembly 110 via the return air duct 144.

Further, the top rear end of the thawing compartment 141 may be provided with an air guide structure 145, 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 compartment 141, arranged below the top wall of the thawing compartment 141 at intervals of a preset 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 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 extends in a longitudinal direction of the thawing compartment 141, and an air guide gap 145c for a thawing air flow to pass through is formed between the adjacent air guide side plates 145 b.

After the flow promoting assembly 110 is opened, the defrosting air flow firstly flows towards the front end of the defrosting drawer 150, then is blocked by the front end of the defrosting drawer 150, climbs to the upper side of the defrosting drawer 150, then flows upwards from the front end of the defrosting drawer 150 and backwards, when the defrosting air flow passes through the air guiding structure 145, the air guiding side plate 145b can guide the defrosting air flow to flow back to the flow promoting assembly 110 from front to back, and the air guiding bottom plate 145a can prevent the defrosting air flow from sinking and re-entering the defrosting drawer 150, so that the circulation effect and the circulation smoothness of the defrosting air flow are improved.

The width of the thawing drawer 150 may be smaller than the width of the thawing compartment 141, and the air return openings 153 are provided at both sides of the thawing drawer 150, and a portion of the thawing air flow blown into the thawing drawer 150 by the flow promoting assembly 110 may flow back to the flow promoting assembly 110 from between the side wall of the thawing drawer 150 and the side wall of the thawing compartment 141 through the air return openings 153.

The air guiding structure 145 may be integrally provided with the mounting frame 142, and the air guiding gap 145c communicates 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.

Further, components such as a fence frame or a tray can be arranged in the thawing drawer 150, so that the bottom of the object to be thawed can be contacted with the thawing airflow, or the object to be thawed can be suspended in the thawing drawer 150, and therefore, in the thawing process, the periphery of the object to be thawed can be effectively contacted with the thawing airflow, the utilization rate of the thawing airflow is improved, the thawing speed is increased, and the thawing quality is improved.
