Description

Technical Field

[0001] The present invention relates to the field of kitchen appliances, and particularly to a thawing device and a cooking appliance having the same. Background Art

[0002] A cooking appliance may include a cabinet, an inner container, and a heating device. A cooking cavity is provided in the inner container. The heating device is disposed in the inner container to heat the air therein. The food to be cooked is placed in the cooking cavity for cooking. For frozen food, before cooking, it is necessary to restore the food from the frozen state to a processable state within a short time. This is not only to meet the requirement of improving the kitchen operation efficiency, but also to reduce the damage of the food during thawing and better retain the original taste, freshness and nutritional components of the food.

[0003] The existing food thawing methods usually include microwave thawing, natural thawing at heating temperature, cold water thawing, running water thawing, etc. The microwave thawing method has uneven heating and is prone to overheating or even cooking of some areas of the food, affecting the food quality. The heating thawing has low efficiency and a long thawing time, and it is easy to expose the food in a dangerous temperature range, such as 4°C to 60°C. The long thawing process will increase the risk of bacterial growth. In addition, when performing cold water thawing, the food needs to be placed in a cold water container for thawing, which is likely to cause excessive thawing of the outer part of the food while the inner part is not completely thawed, and there is also a risk of cross-contamination. Although running water thawing can accelerate the thawing rate, it will increase the waste of water resources.

[0004] In view of this, the present application is proposed. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems in the related art to some extent.

[0006] To this end, according to an embodiment of the present disclosure, a thawing device is proposed, including:

[0007] A housing, configured as a hollow cavity with one end open;

[0008] A carrier body, slidably disposed in the hollow cavity so as to push the carrier body into the hollow cavity or pull at least a part of the carrier body out of the hollow cavity;

[0009] A panel, disposed at one end of the carrier body. When the carrier body is pushed into the interior of the hollow cavity, the panel and the hollow cavity enclose a sealed cavity;

[0010] A container, disposed on the carrier body. The container is used to form a closed thawing cavity for accommodating the food to be thawed and water. An opening of the thawing cavity is provided on the top surface of the container;

[0011] A lid for closing or opening the opening of the thawing chamber;

[0012] A heating pipe provided at one or any combination of the bottom, side, and inside of the container;

[0013] A temperature detection device provided in the thawing chamber for detecting the temperature at the location and defined as the detected temperature;

[0014] A vacuum assembly provided on the carrying body, the vacuum assembly communicating with the thawing chamber for evacuating the thawing chamber;

[0015] A controller electrically connected to the heating pipe, the temperature detection device, and the vacuum assembly, and a target temperature is stored in the controller;

[0016] The controller is configured to supply thawing water into the thawing chamber until a reference water volume is reached, then obtain the detected temperature, and adjust the working state of the heating pipe according to the difference between the detected temperature and the target temperature to heat the thawing water to the target temperature, and maintain the heat exchange between the thawing water and the food to be thawed for a preset duration.

[0017] Based on the above structure, through the coordinated operation of the controller, the heating pipe, the temperature detection device, and the vacuum assembly, precise control of the thawing process is achieved, ensuring sufficient heat exchange between the thawing water and the food to be thawed to achieve the expected thawing effect inside the food. At the same time, the vacuum assembly is used to reduce the air pressure in the thawing chamber, thereby accelerating the heat exchange process, improving the thawing efficiency, and ensuring the thawing quality of the food.

[0018] When the detected temperature is lower than the target temperature, that is, when the difference is greater than 0, the heating pipe is controlled to start.

[0019] When the detected temperature reaches or is greater than the target temperature, that is, when the difference is greater than 0 or less than 0, the heating pipe is controlled to stop.

[0020] In some embodiments, the thawing device further includes:

[0021] A rotating mechanism fixedly provided on the carrying body, the rotating mechanism being connected to the bottom of the container for driving the container to rotate, and the rotating mechanism being electrically connected to the controller;

[0022] A preset rotation logic is stored in the controller, and the controller controls the operation of the rotating mechanism according to the preset rotation logic.

[0023] Among them, the preset rotation logic includes: forward rotation duration, forward rotation intermittent duration, reverse rotation duration, and reverse rotation intermittent duration, for controlling the rotating mechanism to drive the container to rotate forward and backward, and execute cyclically.

[0024] By controlling the rotation of the container, the uniformity and efficiency of thawing are improved, and the heat exchange between the surface of the food material and the low-temperature thawing water can also be accelerated. When the food material rotates in the thawing water, its surface will continuously contact the low-temperature thawing water in the thawing chamber, thereby accelerating the heat transfer and the melting of ice crystals, and the thawing effect can be achieved faster.

[0025] In some of these embodiments, the controller stores the thawing duration corresponding to the weight w of the food material.

[0026] The controller is configured to, after obtaining the weight w of the food material, match the thawing duration ΔT corresponding to the weight w of the food material, and start timing after the detected temperature reaches the target temperature.

[0027] When the timing duration reaches the thawing duration ΔT, it is determined that the thawing is completed. That is, after the thawing water in the thawing chamber reaches the target temperature, continue thawing for the set thawing duration ΔT, and then it is determined that the thawing is completed.

[0028] Using the controller to automatically match the thawing duration according to the weight of the food material can avoid the decline in the quality of the food material caused by over-thawing, and also avoid the influence on subsequent cooking and processing due to insufficient thawing, improving the intelligence and accuracy of thawing.

[0029] In some of these embodiments, the controller stores the temperature rise coefficient δ corresponding to the weight w of the food material n , and the thawing duration ΔT required to thaw a unit weight of food material under the reference water volume 0 , and the controller is configured to

[0030] After obtaining the weight w of the food material, according to the temperature rise coefficient δ n and the thawing duration ΔT 0 calculate the thawing duration ΔT based on the preset thawing logic.

[0031] The preset thawing logic is expressed as the following calculation model:

[0032] ΔT = δ n *ΔT 0 .

[0033] Based on the above preset thawing logic, it is possible to automatically calculate the actual required thawing duration ΔT according to the weight of the food material and the temperature rise coefficient, so as to ensure that the thawing is completed within the appropriate thawing duration, which not only ensures the thawing effect but also avoids the situation of over-thawing or insufficient thawing.

[0034] In some of these embodiments, the thawing device further includes:

[0035] A pressure relief valve, which communicates with the vacuum assembly and the thawing chamber, and the pressure relief valve is electrically connected to the controller.

[0036] The pressure relief hole is blocked by the pressure relief valve during the thawing process to ensure a negative pressure environment in the thawing chamber, thereby maintaining the stability of the thawing environment. When the thawing is completed, the controller can control the pressure relief valve to open to reduce the internal pressure of the thawing chamber.

[0040] A drainage pump, which is arranged on the pipeline, and the drainage pump is electrically connected to the controller. When the control valve is opened and the drainage pump is started, the drainage pump will draw the thawing water in the thawing chamber into the water storage box through the pipeline.

[0041] By means of the coordinated control of the control valve and the drainage pump, the controller can monitor the thawing process and drain the thawing water in time after the thawing is completed, preventing the thawing water from staying in the thawing chamber, reducing the growth of bacteria, and ensuring the safety of food ingredients.

[0042] In some embodiments, the thawing device further includes:

[0043] A first in-place switch, which is arranged on the side of the bearing body away from the panel, and the first in-place switch is electrically connected to the controller, and is used to detect whether the bearing body is pushed into the hollow cavity to generate a first in-place detection signal. The controller is configured to receive the first in-place detection signal and judge whether the bearing body is in place.

[0044] In some embodiments, it further includes: a second in-place switch, which is arranged at the bottom of the water storage box, and the second in-place switch is electrically connected to the controller, and is used to detect whether the water storage box is placed to generate a second in-place detection signal. The controller is configured to receive the second in-place detection signal and judge whether the water storage box is in place.

[0045] The controller is used to realize the automatic detection of the water storage box and the water level in the water storage box, preventing operation failures caused by the corresponding components not being in place.

[0046] In some embodiments, the thawing device further includes:

[0047] A touch display screen, which is arranged on the panel or the housing and is electrically connected to the controller. The touch display screen is used to provide an interaction interface to receive touch commands and display interaction information through the interaction interface.

[0048] The controller is configured to obtain a start instruction according to the touch instruction, so that the thawing device starts the thawing function according to the start instruction.

[0049] In some embodiments, the thawing device further includes:

[0050] A slide rail assembly, which is arranged between the housing and the carrying body, and realizes the relative sliding of the carrying body in the hollow cavity through the slide rail assembly, thereby helping the user to easily push or pull the carrying body, improving the operation convenience and enhancing the user experience.

[0051] An embodiment of the present disclosure also provides a cooking device, including:

[0052] A box body, which is used to form the external contour of the cooking device;

[0053] An inner container, which is arranged inside the box body, and the inner container is used to form a cooking cavity; a cooking cavity opening is provided at the front end of the cooking cavity;

[0054] A box door, which is used to open or close the cooking cavity opening;

[0055] A heating device, which is arranged between the inner container and the box body and is used to heat the cooking cavity; the heating device includes:

[0056] A plurality of cooking heating tubes, which are arranged at one or a combination of positions on the back, top, and bottom of the inner container;

[0057] A cooking controller, which is electrically connected to the heating device;

[0058] A thawing device, which is arranged inside the box body and is used for thawing;

[0059] Among them, the thawing device includes:

[0060] A housing, which is set as a hollow cavity with one end open;

[0061] A carrying body, which is slidably arranged in the hollow cavity so as to push the carrying body into the hollow cavity or pull at least a part of the carrying body out of the hollow cavity;

[0062] A panel, which is arranged at one end of the carrying body. When the carrying body is pushed into the hollow cavity, the panel and the hollow cavity enclose a sealed cavity;

[0063] A container, which is arranged on the carrying body. The container is used to form a closed thawing cavity for accommodating the food to be thawed and water, and a thawing cavity opening is provided on the top surface of the container;

[0064] A cover body, which is used to close or open the thawing cavity opening;

[0065] A heating pipe, which is provided at one or any combination of the bottom, side, and inside of the container;

[0066] A temperature detection device, which is provided in the thawing chamber and is used to detect the temperature at the location where it is located, and is defined as the detected temperature;

[0067] A vacuum assembly, which is provided on the bearing body, and the vacuum assembly is connected to the thawing chamber for evacuating the thawing chamber;

[0068] A controller, electrically connected to the heating pipe, the temperature detection device, and the vacuum assembly, and a target temperature is stored in the controller;

[0069] The controller is configured to provide thawing water into the thawing chamber until a reference water volume is reached, then obtain the detected temperature, and adjust the working state of the heating pipe according to the difference between the detected temperature and the target temperature, so as to heat the thawing water to the target temperature, and maintain the heat exchange between the thawing water and the ingredients to be thawed for a preset duration.

[0070] By integrating a thawing device in the cooking device, users can pre-process the ingredients in the thawing device without having to wait for the cooking device to be idle. Once the thawing is completed, the ingredients can be quickly transferred to the cooking chamber for cooking, thus greatly shortening the overall cooking time and improving the cooking efficiency. At the same time, the thawing chamber of the thawing device is independently provided from the cooking chamber, avoiding the possible contamination problem caused by directly thawing the ingredients in the cooking chamber.

[0087] To make the purpose and implementation manners of the present application clearer, the following will clearly and completely describe the exemplary implementation manners of the present application in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0088] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the following described implementation manners, rather than intending to limit the implementation manners of the present application. Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0089] The terms "first", "second", "third", etc. in the description, claims and the above drawings of the present application are used to distinguish similar or like objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that such terms can be interchanged under appropriate circumstances.

[0090] The terms "comprising" and "having" and any variations thereof are intended to cover but not exclusively include. For example, a product or device including a series of components does not necessarily have to be limited to all the components clearly listed, but may include other components not clearly listed or inherent to these products or devices.

[0091] The present application provides a thawing device 1, which is applied to a cooking device 2. The thawing device 1 will be described below with reference to the accompanying drawings.

[0092] Existing cooking devices 2 have incorporated a thawing function. Such a thawing device 1 is usually combined with the heating system, steam generation system, etc. of the cooking device 2 to form an integral unit. During the thawing process, by controlling the heating temperature and the amount of steam, the thawing process is achieved by itself, mainly relying on its heating system.

[0093] When the cooking device 2 is powered on, the heating element inside it starts to work and generates heat, causing the ice crystals in the food to gradually melt. The thawing method is relatively single and the thawing duration is relatively long. However, during the thawing process, the ice crystals inside the food ingredients need to melt into water. If the thawing container remains stationary, the heat transfer may be uneven, resulting in some food ingredients thawing too quickly while some thawing too slowly.

[0094] In view of this, the present application provides a thawing device 1, which will be described below with reference to the accompanying drawings.

[0095] Referring to Figures 1-5 , the thawing device 1 may include a housing 11. The housing 11 is arranged as a hollow cavity with one end open, and a ventilation opening 111 is provided at the top of the housing 11, which communicates the hollow cavity with the outside;

[0096] As Figure 2 shown, the thawing device 1 may include a carrying body 12. The carrying body 12 is slidably arranged in the hollow cavity so as to push the carrying body 12 into the hollow cavity or pull at least a part of the carrying body 12 out of the hollow cavity, facilitating the user to put in or take out the food ingredients to be thawed;

[0097] The thawing device 1 may include a panel 121. The panel 121 is arranged at one end of the carrying body 12. When the carrying body 12 is pushed into the interior of the hollow cavity, the panel 121 and the hollow cavity enclose a sealed cavity.

[0098] The thawing device 1 may include a container 13, which is arranged on the carrying body 12. The container 13 is used to form a closed thawing cavity 131 for accommodating the food ingredients to be thawed and water. The top surface of the container 13 is provided with an opening of the thawing cavity 131, facilitating the user to put in or take out the food ingredients, as well as add or drain the thawing water. The container 13 has a cylindrical structure.

[0099] Based on the cylindrical structure, the turbulence and eddy current of the fluid in the container 13 can be reduced, and the flow efficiency can be improved.

[0100] Continuing to refer to Figure 2As shown, the thawing device 1 may include a cover 132 for closing or opening the opening of the thawing chamber 131 to ensure the sealing property during the thawing process;

[0101] Combined with Figure 4 As shown, the thawing device 1 may include a heating pipe 14 disposed at one or any combination of the bottom, side, and inside of the container 13 for heating the thawing water.

[0102] The heating pipe 14 may be arranged to surround the bottom of the container 13 to maximize the direct contact area between the heating pipe 14 and the water, thereby improving the heating efficiency.

[0103] The heating pipe 14 may be provided as a single or multiple heating pipes 14. If multiple heating pipes 14 are provided, they may be evenly distributed to ensure uniform heating.

[0104] The heating pipe 14 may also be disposed on the side of the container 13, close to the bottom of the container 13 and below the lowest water level height to ensure that the heating pipe 14 is always covered by water and avoid dry burning.

[0105] The thawing device 1 may include a temperature detection device disposed in the thawing chamber 131 for detecting the temperature at the location and defined as the detected temperature. The position of the temperature detection device is below the water level line to ensure accurate measurement of the temperature of the thawing water.

[0106] Reference Figure 3 As shown, the thawing device 1 may include a vacuum assembly 15 disposed on the carrier body 12. The vacuum assembly 15 is connected to the thawing chamber 131 for evacuating the thawing chamber 131 to provide at least a negative pressure environment for thawing.

[0107] The thawing device 1 may include a controller electrically connected to the heating pipe 14, the temperature detection device, and the vacuum assembly 15. A target temperature is stored in the controller. After providing thawing water to a reference water volume in the thawing chamber 131, the temperature detection device measures the water temperature in the thawing chamber 131 in real time, i.e., the detected temperature.

[0108] The controller is configured to obtain the detected temperature, adjust the working state of the heating pipe 14 according to the difference between the detected temperature and the target temperature to heat the thawing water to the target temperature, and continue the heat exchange between the thawing water and the food to be thawed for a preset duration, thereby ensuring that sufficient heat exchange can occur between the thawing water and the food to be thawed to achieve the expected thawing effect inside the food. At the same time, the vacuum assembly 15 is used to reduce the air pressure in the thawing chamber 131, thereby accelerating the heat exchange process.

[0109] Through the coordinated operation of the controller, the heating pipe 14, the temperature detection device, and the vacuum assembly 15, precise control of the thawing process is achieved, the thawing efficiency is improved, and the thawing quality of the food is ensured.

[0110] When the detected temperature is lower than the target temperature, that is, when the difference is greater than 0, the heating tube 14 is controlled to start.

[0111] When the detected temperature reaches or is higher than the target temperature, that is, when the difference is greater than 0 or less than 0, the heating tube 14 is controlled to stop or the power of the heating tube 14 is reduced to prevent the water temperature from being too high.

[0112] The above-mentioned target temperature has a temperature range between 0°C and 45°C.

[0113] By setting the target temperature within the above temperature range, it is possible to avoid the problem that the surface of the food material will quickly heat up while the inside is still in a frozen state. Based on the target temperature, the low-temperature thawing water can evenly increase the temperature of the food material, thus better maintaining the nutrition and taste of the food material.

[0114] To facilitate the water supply operation, a water level line corresponding to the reference water volume is marked in the thawing chamber 131, and the water level line is a fixed water level. Or it is set based on the type or weight of the food material, or the maximum water level line and the minimum water level line are set based on the capacity of the thawing chamber 131.

[0115] In some of the embodiments, referring Figure 4 as shown, the thawing device 1 further includes: a rotating mechanism. The rotating mechanism is fixedly arranged on the bearing body 12, the rotating mechanism is connected to the bottom of the container 13, and is used to drive the container 13 to rotate. The rotating mechanism is electrically connected to the controller.

[0116] The controller stores a preset rotation logic, and the controller controls the operation of the rotating mechanism according to the preset rotation logic.

[0117] In the above-mentioned embodiments, the preset rotation logic includes: the forward rotation duration, the forward rotation intermittent duration, the reverse rotation duration, and the reverse rotation intermittent duration, which are used to control the rotating mechanism to drive the container 13 to rotate forward and reverse, and execute cyclically.

[0118] The specific durations of the forward rotation duration, the forward rotation intermittent duration, the reverse rotation duration, and the reverse rotation intermittent duration can be configured according to multiple factors such as the weight of the food material to be thawed, the weight, and the temperature of the thawing water.

[0119] By controlling the rotation of the container 13, the food material to be thawed in the thawing chamber 131 can be heated more evenly in the thawing water, ensuring that each part of the food material can receive the same heat transfer, and can also reduce the water temperature deviation in the thawing water, thereby improving the uniformity and efficiency of thawing.

[0120] In addition, rotating the thawing chamber 131 can also accelerate the heat exchange between the surface of the food material and the low-temperature thawing water. When the food material rotates in the thawing water, its surface will continuously come into contact with the low-temperature thawing water in the thawing chamber 131, thereby accelerating the heat transfer and the melting of ice crystals. Compared with static thawing, the thawing effect can be achieved faster.

[0121] In the above embodiments, referring to Figures 3-4 As shown, the rotating mechanism at least includes a power component 161, such as a motor, for providing the energy required for rotation.

[0122] In another embodiment, the rotating mechanism further includes transmission components, such as pulleys, bevel gears, etc., for transmitting the rotational motion of the power component 161 to the container 13 or connecting to the container 13 through a rotating component 162 to realize driving the container 13 to rotate.

[0123] By way of example but not limitation, when the motor starts, the generated rotational power is directly or through the transmission components and the rotating component 162. The rotating component 162 transmits to the container 13, thereby driving it to perform a rotational motion.

[0124] This rotational motion can be uniform or variable speed, and is specifically realized by flexibly adjusting the preset rotation logic.

[0125] In some of these embodiments, the controller stores the thawing duration corresponding to the weight w of the food material. The controller is configured to, after obtaining the weight w of the food material, match the thawing duration △T corresponding to the weight w of the food material, and start timing after detecting that the temperature reaches the target temperature, and keep the detected temperature at the target temperature during the timing process.

[0126] When the timing duration reaches the thawing duration △T, it is determined that the thawing is completed. That is, after the thawing water in the thawing chamber 131 reaches the target temperature and continues to thaw for the set thawing duration △T, it is determined that the thawing is completed.

[0127] Using the controller to automatically match the thawing duration according to the weight of the food material can avoid the decline in the quality of the food material caused by over-thawing, and also avoid the influence on subsequent cooking and processing due to insufficient thawing, improving the intelligence and accuracy of thawing.

[0128] In the above embodiments, for the reference water volume, the duration T1 required to heat it from an initial temperature to the target temperature using the heating tube 14 can be measured in advance. Through multiple groups of tests, multiple durations T1 corresponding to different water level lines can be obtained.

[0129] To facilitate matching the thawing duration, the controller stores a food material weight interval table, and the thawing duration △T corresponding to the food material weight is configured for different food material weights in the food material weight interval table.

[0130] In some of these embodiments, a weighing module is provided at the bottom of the container 13. The weighing module is electrically connected to the aforementioned controller. The weighing module detects the weight of the food ingredients and sends it to the controller, achieving precise monitoring of the weight of the food ingredients in the container 13. After receiving the weight of the food ingredients, the controller can match the corresponding thawing duration and precisely control the thawing process.

[0131] In some of these embodiments, the controller stores a heating-up coefficient δ corresponding to the weight w of the food ingredients n , and the thawing duration △T required to thaw a unit weight of food ingredients under the reference water volume 0 . The controller is configured to, after obtaining the weight w of the food ingredients, according to the heating-up coefficient δ n and the thawing duration △T 0 calculate the thawing duration △T based on a preset thawing logic.

[0132] The preset thawing logic is represented by the following calculation model:

[0133] △T = δ n *△T 0 .

[0134] In the above embodiments, the controller stores a heating-up rate V for thawing a unit weight (1 kilogram) of food ingredients based on the reference water volume 0 , and the heating-up rate V of the food ingredients with a weight w of the food ingredients thawed under the reference water volume n . The heating-up rate is used to represent how fast the detected temperature is heated to the target temperature by the heating tube 14 when the detected temperature is lower than the target temperature. The unit of the weight w of the food ingredients is kilograms.

[0135] In the above embodiments, the heating-up coefficient δ n is calculated based on the following calculation model: δ n = V 0 / V n .

[0136] In the above embodiments, the heating-up rate is calculated based on the following calculation model:

[0137] Heating-up rate = (Target temperature - Detected temperature) / Heating-up duration.

[0138] Based on the above preset thawing logic, it is possible to automatically calculate the actual required thawing duration △T according to the weight of the food ingredients and the heating-up coefficient, so as to ensure that the thawing is completed within an appropriate thawing duration, which not only guarantees the thawing effect but also avoids the situation of over-thawing or under-thawing.

[0139] Automatically calculating the thawing duration according to the weight of the food ingredients and the heating-up coefficient enables the thawing device 1 to more intelligently adapt to the thawing requirements of different food ingredients, improving the accuracy and efficiency of thawing. At the same time, it also reduces the operation burden of the user, making the thawing process more simple and fast.

[0140] In another embodiment, by collecting data on the heating rate corresponding to a series of different ingredient weights, a mathematical model is selected to fit the heating coefficient, such as a linear model, a polynomial model, an exponential model, etc.

[0141] The model parameters are fitted by the least squares method or other optimization algorithms to obtain the parameters of the fitted model. Furthermore, a curve of the heating coefficient varying with the ingredient weight is obtained.

[0142] Using the fitted model, the trend of the heating coefficient varying with the ingredient weight can be intuitively displayed, the required heating coefficient information can be obtained more quickly, the cost of data collection work can be reduced, and the future heating coefficient can also be predicted and trend analyzed.

[0143] The thawing device 1 may include a pressure relief valve that communicates with the vacuum assembly 15 and the thawing chamber 131, and the pressure relief valve is electrically connected to the controller.

[0144] In some embodiments, the pressure relief valve is provided on the cover body 132 with a pressure relief hole, and the pressure relief valve blocks the pressure relief hole.

[0145] The pressure relief hole is blocked by the pressure relief valve during the thawing process. The purpose of this is to ensure the negative pressure environment in the thawing chamber 131, thereby maintaining the stability of the thawing environment. When the thawing is completed, the controller can control the pressure relief valve to open to reduce the internal pressure of the thawing chamber 131.

[0146] The thawing device 1 may include a water storage box 17, which is provided on the bearing body 12, and the water storage box 17 communicates with the thawing chamber 131 through a pipeline for storing the thawing water after use.

[0164] Based on this, when any area of the extrusion panel 121 is pressed, the bearing body 12 can be locked and fixed or unlocked and ejected within the housing 11, helping the user to easily push or pull the bearing body 12 and improving the operation convenience.

[0165] Reference Figure 6 As shown, illustrate the control logic of the thawing process of the thawing device 1 in the above embodiments.

[0166] Step S101: Click on the touch display screen of the thawing device 1, select the start command through its interaction interface, and enter the thawing mode.

[0167] Step S102: Perform in-place detection. Use the first in-place switch 18 to detect whether the bearing body 12 is in place, and use the second in-place switch and the liquid level sensor to automatically detect whether the water storage box 17 is in place and / or empty.

[0168] The controller obtains the detection result. If it is determined that at least one of the water storage box 17 is not in place, the water level of the water storage box 17 does not reach the reference water level, and the bearing body 12 is not in place exists, a prompt identifier or prompt text will be displayed in the interaction interface in the form of a pop-up window to remind the user, and the above detection result will be obtained again until the water storage box 17 is in place, the water level of the water storage box 17 reaches the reference water level, and the bearing body 12 is not in place, then the thawing stage is allowed to enter.

[0169] Step S103: The user puts the thawed food into the container 13 and enters the food weight on the interaction interface to start thawing.

[0170] Step S104: Control the heating tube 14 to heat the container 13 and start the vacuum pump to maintain a preset vacuum degree. At this time, the temperature detector detects the temperature of the thawing water inside the container 13, and the controller judges the difference between the detected temperature T and the target temperature T0, starts and stops the heating tube 14 to reach and maintain the target temperature T0.

[0171] Step S105: The rotating mechanism drives the container 13 to rotate intermittently forward and backward.

[0172] Step S106: The controller determines the thawing duration according to the weight of the food material, judges whether the thawing is completed. If the thawing duration is reached, it is judged that the thawing is completed.

[0173] Step S107: The thawing chamber 131 is dehydrated and depressurized. The controller controls the control valve 171 to open and the drain pump 172 to start, extracts the thawing water into the water storage box 17, and controls the pressure relief valve to start for a period of time to complete the pressure relief.

[0174] Step S108: Prompt on the interaction interface that the thawing is completed so that the user can take out the thawed food material, and control the control valve 171 of the thawing chamber 131 to close.

[0175] The above step S105 can also be executed in parallel with step S104.

[0176] Based on the above steps, parameters such as the thawing duration and temperature can be automatically adjusted according to the weight of the food material to achieve intelligent thawing. This not only improves the thawing efficiency, helps to maintain the thawing quality of the food material, but also uses the vacuum assembly 15 to provide a negative pressure environment, combined with the rotating mechanism, to accelerate the thawing speed and improve the thawing uniformity.
