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 present utility model provides a low temperature and high humidity thawing apparatus 10, fig. 1 is a structural view of the low temperature and high humidity thawing apparatus 10 according to an embodiment of the present utility model, fig. 2 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 and 2, the low temperature and high humidity thawing apparatus 10 may include a thawing tank 140, a flow-promoting assembly 110, and a heating assembly 120.

The thawing box 140 defines a forwardly open thawing compartment 143 for receiving the thawed objects. The thawing box 140 is provided with a thawing door 150, and the thawing door 150 is used for opening and closing the thawing compartment 143 to provide a relatively airtight thawing environment for the articles to be thawed during thawing.

The defrost door 150 can be single or double door, shown in the figures as a single door. A vertically extending pivot shaft is provided between the thawing door 150 and the left or right side of the thawing tank 140 such that the thawing door 150 can be turned open toward the left or right side of the thawing tank 140. Alternatively, a pivot shaft extending in a lateral direction is provided between the defrosting door 150 and the top of the defrosting container 140, so that the defrosting door 150 can be turned over and opened toward the upper side of the defrosting container 140, and the defrosting door 150 is shown in the drawing to be turned over and opened.

In order to maintain the position stable after the defrosting door 150 is turned upward, the front end surface of the defrosting box 140 may be designed as a slope gradually inclined forward from top to bottom. Thus, after the thawing door 150 is opened, the upward turning angle of the thawing door 150 is larger than 90 degrees, and the gravity center of the thawing door 150 is relatively close to the back, so that the thawing door is prevented from automatically turning forward and falling down.

An air supply opening 144 is formed in the top wall of the thawing compartment 143, an air return opening 145 is formed in the side wall of the thawing compartment, and a drainage air duct 146 is defined between the air supply opening 144 and the air return opening 145. The flow-promoting assembly 110 is disposed at the air supply opening 144 for blowing air toward the object to be thawed, such that the air flow blown to the object to be thawed flows back to the flow-promoting assembly 110 from the return air opening 145 through the drainage air duct 146. In this way, the flow promoting assembly 110 can circulate the air flow in the thawing chamber 143, and the air flow can exchange heat with the to-be-thawed object when passing through the to-be-thawed object, so as to accelerate the thawing speed of the to-be-thawed object.

Further, two opposite side walls of the thawing box 140 are respectively provided with an air return opening 145, and a drainage air duct 146 is formed between the air supply opening 144 and the two air return openings 145. That is, the present embodiment controls the circulation of the air flow in the thawing compartment 143 by using the top air supply and the two-side air return, so that the circulation speed of the air flow can be increased, and the air flow is smoother.

The thawing box 140 may include an outer box 141 and an inner frame 142, and fig. 3 is an exploded view of the outer box 141 and the inner frame 142 of the thawing box 140 according to an embodiment of the present utility model, referring to fig. 3, the inside of the inner frame 142 defining a thawing compartment 143. The air supply port 144 and the air return port 145 are both formed on the inner frame 142, and drainage air channels 146 are formed between the inner frame 142 and the side walls and between the top walls of the outer box 141. Referring to fig. 2, the air supply opening 144 is located at the center of the top wall of the inner frame 142, the air return opening 145 is located at the bottoms of the two side walls of the inner frame 142, the drainage air duct 146 corresponds to an inverted U shape, and covers the two sides and the top of the thawing compartment 143.

The heating component 120 can be arranged in the drainage air duct 146, so that the air flow flowing back into the drainage air duct 146 is heated, the temperature of the air flow is increased, the air flow with higher temperature is blown to the object to be defrosted by the flow promoting component 110, the heat exchange amount between the air flow and the object to be defrosted can be increased, the defrosting speed of the object to be defrosted is obviously improved, the waiting time of a user is shortened, and the use experience of the user is improved.

Specifically, the heating assembly 120 may include a heat accumulating plate 121, and the working process of the heat accumulating plate 121 includes a heat storing stage and a heat releasing stage, so that when the air flow in the air guiding duct 146 needs to be heated, the heat accumulating plate 121 can be controlled to release heat, which is beneficial to saving the heating cost.

The heat conductivity of the heat accumulation plate 121 may be 0.026W/(mK) to 400W/(mK), and the phase change point temperature may be-18 ℃ to 30 ℃. By adopting the heat storage plate 121 with the heat conductivity coefficient and the phase change point temperature, the air flow flowing back to the flow promoting assembly 110 can be sufficiently heated, and the higher temperature of the air flow when the air flow is blown to the object to be thawed can be effectively ensured.

The heat accumulation plate 121 may be disposed adjacent to one side of the flow promoting assembly 110 or disposed around the flow promoting assembly 110, so that the air flow can be directly blown by the flow promoting assembly 110 after being heated by the heat accumulation plate 121, which shortens the flow length of the air flow after being heated, and is beneficial to reducing the heat loss of the air flow in the flow process.

Further, the heating assembly 120 may further include at least one heat dissipation fin 122, and a heat transfer tube 123 is connected between the heat accumulation plate 121 and the heat dissipation fin 122, and the heat accumulation plate 121 transfers the heat generated by the heat transfer tube 123 to the heat dissipation fin 122, so as to increase the heat dissipation area of the heat accumulation plate, thereby improving the heating efficiency and realizing rapid heating of the air flow.

The heat accumulation plate 121 may be disposed at an upper section of the drainage air duct 146 in the thawing compartment 143, the number of the heat dissipation fins 122 may be two, the two heat dissipation fins 122 are disposed at two side sections of the drainage air duct 146 in the thawing compartment 143, and a heat transfer tube 123 is connected between each heat dissipation fin 122 and the heat accumulation plate 121. In this way, the air flowing back to the flow-promoting assembly 110 from the return air inlets 145 on both sides can be heated by the heat radiating fins 122, improving the uniformity of heating.

Referring to fig. 4, the heating assembly 120 may further include at least one heat radiating plate, with which the heat accumulating plate 121 is abutted, and the heat radiating area thereof is increased by the heat radiating plate. That is, the heat accumulation plate 121 can directly transfer the generated heat to the heat dissipation plate, and the air flow is not only in contact with the surface of the heat accumulation plate 121, but also in contact with the surface of the heat dissipation plate during the process of flowing back to the flow promotion assembly 110, so that the heating efficiency of the heat accumulation plate 121 can be improved, and the rapid heating of the air flow can be realized.

At least one of the heat dissipation plates may include a first heat dissipation plate 124, where the first heat dissipation plate 124 is wrapped on an inner wall of the drainage air duct 146 adjacent to one side of the thawing compartment 143, that is, an upper surface of a top wall and outer surfaces of two side walls of the inner frame 142, and the heat storage plate 121 is fixed on the first heat dissipation plate 124. This allows the first heat sink 124 to be designed large enough to adequately heat the air flow within the limited conduction air path 146. In addition, the first heat dissipation plate 124 wraps the upper surface of the top wall of the inner frame 142, and can play a role in radiation heat transfer to the inside of the thawing compartment 143, heat the inside of the thawing compartment 143, and improve the air flow temperature of the air flow flowing back into the drainage air duct 146, thereby being beneficial to improving the heat utilization rate.

The at least one heat dissipation plate may further include a second heat dissipation plate 125, the second heat dissipation plate 125 being disposed above the first heat dissipation plate 124, the second heat dissipation plate 125 and the first heat dissipation plate 124 sandwiching the heat accumulation plate 121 from upper and lower sides. That is, the heat generated by the heat storage plate 121 is transferred to the first heat dissipation plate 124 and the second heat dissipation plate 125 through the upper and lower surfaces, and the air flow contacts the surface of the second heat dissipation plate 125 to transfer heat during the flowing process of the air flow in the air drainage duct 146, so that the temperature of the second heat dissipation plate 125 is reduced, and the first heat dissipation plate 124 can play a role in radiation heat transfer to the second heat dissipation plate 125, so that the heat utilization rate is further improved.

The second heat dissipation plate 125 may be adapted to the shape of the first heat dissipation plate 124, and the heat storage plate 121 may be designed to be thinner, so that the distance between the first heat dissipation plate 124 and the second heat dissipation plate 125 is smaller, so that the first heat dissipation plate 124 can radiate heat to the second heat dissipation plate 125.

The periphery of the second heat dissipation plate 125 and the periphery of the first heat dissipation plate 124 should be connected in a sealing manner, so that the air flow is prevented from entering the gap between the two, and the flow smoothness of the air flow is prevented. For example, the periphery of the second heat dissipation plate 125 has a flange bent toward the first heat dissipation plate 124, or the periphery of the first heat dissipation plate 124 has a flange bent toward the second heat dissipation plate 125, so as to form a relatively sealed structure between the second heat dissipation plate 125 and the first heat dissipation plate 124. Of course, the periphery of the second heat dissipation plate 125 and the first heat dissipation plate 124 may be sealed by filling sealant.

Of course, in other embodiments, the heat accumulation plate 121 may be designed to be thicker, so that the space between the first heat dissipation plate 124 and the second heat dissipation plate 125 is larger, the second heat dissipation plate 125 is wrapped on the inner wall of the drainage air duct 146 on the side far away from the thawing compartment 143, that is, the lower surface of the top wall and the inner surfaces of the two side walls of the outer case 141, in this way, the heat accumulation plate 121 can block the flow velocity of the air flow to a certain extent, the effect of radiation heat transfer between the first heat dissipation plate 124 and the second heat dissipation plate 125 is worse, but the air flow can contact the surfaces of the first heat dissipation plate 124 and the second heat dissipation plate 125 at the same time.

The first heat dissipation plate 124 and the second heat dissipation plate 125 are provided with yielding ports (not shown in the figure) corresponding to the flow promotion components 110. The purpose of setting the abdication opening is mainly to avoid the first heat dissipation plate 124 and the second heat dissipation plate 125 to form shielding to the air supply outlet 144, so as to ensure that the air flow in the drainage air duct 146 can smoothly flow out from the air supply outlet 144.

The heat dissipation plate can be an aluminum heat dissipation plate, and the aluminum heat dissipation plate has high heat conductivity and good heat transfer property. The thickness of the heat dissipation plate can be 0.2 mm-8 mm, such as 0.5mm, 2mm, 3mm, etc., and the heat dissipation plate in the thickness range has good structural strength, is not easy to damage, has light weight, is favorable for reducing the whole weight of the thawing box 140, and is easy for a user to move the thawing box 140.

Considering that the to-be-thawed is continuously blown by high-temperature air flow, juice is easy to run off, the surface is easy to air-dry, the to-be-thawed object is hard, and the edible mouthfeel after cooking is affected. For this reason, the low-temperature and high-humidity thawing apparatus 10 of the present utility model may further include a humidifying unit that may be provided in the thawing compartment 143 to supply a humidified air flow into the thawing compartment 143, thereby increasing the internal humidity of the thawing compartment 143 and maintaining the surface of the object to be thawed moist.

Fig. 5 is a mounting structure diagram of a humidifying assembly and an inner frame 142 according to an embodiment of the present utility model, and referring to fig. 5, the humidifying assembly may include a water storage tank 131 for storing humidifying water and an atomizing head 132, the atomizing head 132 communicating with the inside of the water storage tank 131 for converting the humidifying water into a humidifying air flow, and regulating the internal humidity of the defrosting compartment 143 by the humidifying air flow.

The water storage box 131 can be slidably connected to the front end of the thawing tank 140, and after the thawing door 150 is turned upwards and opened, the water storage box 131 can be exposed, and a user can conveniently supplement humidification water into the water storage box 131 by pulling the water storage box 131 forwards.

The front end of the inner frame 142 of the thawing box 140 is provided with a sliding groove 147, the sliding groove 147 extends along the depth direction of the thawing compartment 143, and the water storage box 131 is inserted into the sliding groove 147. The shape of the sliding groove 147 should be matched with the shape of the water storage box 131 as much as possible, so that the water storage box 131 can be kept stable after being pushed into the sliding groove 147.

The sliding groove 147 may be located above the thawing compartment 143, the bottom of which is in communication with the thawing compartment 143, and after the water storage box 131 is completely pushed into the sliding groove 147, the water storage box 131 is located at the lower side of the flow-promoting assembly 110, and at least partially protrudes into the thawing compartment 143. In this way, the atomizing head 132 can be fixed to the side of the water storage tank 131 adjacent to the air supply path such that the atomizing head 132 supplies the humidified air flow toward the air supply path within the defrosting compartment 143.

Therefore, the air flow blown to the object to be defrosted has high humidity, and the problem that the surface of the object to be defrosted is air-dried in the process of exchanging heat with the surface of the object to be defrosted is avoided.

The sliding groove 147 is provided with a bridging plate 148 at both sides, and both sides of the water storage case 131 may be supported on the bridging plate 148. The bridging plates 148 are shown in the figures at the bottom of both sides of the sliding chute 147, and the bottom of the water storage cartridge 131 is supported on the bridging plates 148 when it is pushed into the sliding chute 147. In other embodiments, the bridging plate 148 may be located at the middle of both sides of the sliding groove 147, and accordingly, both sides of the water storage box 131 are provided with the bridging grooves which are matched with the bridging plate 148.

The front end of the water storage box 131 is provided with a baffle, the lower edge of which is lower than the top wall of the thawing compartment 143. That is, the lower edge of the baffle is lower than the upper edge of the forward opening, and when the water storage cartridge 131 is completely pushed into the sliding groove 147, the user can catch the lower edge of the baffle through the forward opening, thereby conveniently pulling the water storage cartridge 131 forward.

Since the atomizing head 132 is fixed on the water storage tank 131 and can be pulled out forward along with the water storage tank 131, the power supply mode of the atomizing head 132 needs to be considered. The humidifying assembly of the present embodiment may further include a wireless power supply 133, wherein the wireless power supply 133 is configured to connect the atomizing head 132 to an external power source and to allow the atomizing head 132 to operate in a controlled manner.

The wireless power supply 133 may include a transmitting coil 133a and a receiving coil 133b, the transmitting coil 133a may be fixed at the top of the inner frame 142, the receiving coil 133b may be fixed at the top of the water storage box 131, and when the water storage box 131 is completely pushed into the sliding groove 147, the transmitting coil 133a and the receiving coil 133b are disposed up and down oppositely, and the interval distance between them is less than 10mm. Since the operation principle of the wireless power supply 133 is well known to those skilled in the art, the description thereof is omitted herein.

The straight distance between the atomizing head 132 and the air supply path for supplying the humidified air flow may be 10mm to 300mm, for example, 10mm, 20mm, 30mm, 50mm, etc., so that the loss before mixing the humidified air flow is reduced and the utilization rate of the humidified air flow is improved.

The tray assembly 160 can hold the defrosting water generated in the defrosting process of the object to be defrosted, so that the defrosting water is prevented from flowing to the bottom wall of the defrosting room 143, and the subsequent cleaning work of the defrosting room 143 is saved.
