Description

Technical Field

[0001] This utility model relates to the field of air-dried meat production technology, and in particular to the box structure of an air-dried meat device. Background Technology

[0002] Fresh beef is not usually cooked and eaten directly. Instead, it needs to be processed in a unique way before cooking. Among these processes, beef processed using dry aging technology is a favorite among people. Uneaten pieces of meat are placed in cellars or cold storage to air dry. Due to the corresponding humidity and temperature, the original dry aging process is achieved. After a period of time, residents accidentally discovered that the aged meat had a better flavor, and thus the dry aging technology was born.

[0003] CN220823921U discloses a household beef dryer, including an aging chamber, and further comprising: an aging chamber cover, which is disposed at the top of the aging chamber and has multiple mounting slots on its surface; a bottom cover, which is also installed at the bottom of the aging chamber; an electronic scale assembly, which is installed on the upper surface of the aging chamber cover for measuring the weight of the beef; an aging rack, which is disposed inside the aging chamber and on which fresh beef is placed; and multiple UCV lamps, which are evenly distributed at the bottom of the electronic scale assembly to sterilize the fresh beef placed on the aging rack; wherein, a fan is also installed at the bottom of the electronic scale assembly to blow air at a constant speed onto the surface of the fresh beef; in addition, the entire beef dryer is placed inside a refrigerator, and the temperature and humidity inside are controlled by the refrigerator.

[0004] The household beef air dryer disclosed in CN220823921U uses a refrigerator-based humidity control system, which cannot accurately control the air drying conditions for the meat, leaving room for improvement in the quality of the dried meat.

[0005] CN220823921U does not mention the specific method for making dried meat, and users can only rely on their own senses to air-dry it, so there is room for improvement in the quality of the dried meat.

[0006] The household beef dehydrator disclosed in CN220823921U does not disclose the materials used to manufacture the dehydration chamber. However, in order to quickly unify the temperature inside the dehydration chamber with that of a refrigerator, the chamber needs to be made using as many high thermal conductivity materials as possible, such as stainless steel. However, dehydration chambers made of high thermal conductivity materials such as stainless steel are opaque, so setting up an observation window on the chamber requires assembling components made of different materials, resulting in a complex assembly process and high production costs. Utility Model Content

[0007] One objective of this invention is to solve or alleviate the aforementioned technical problems.

[0008] The present invention employs a box structure for a meat drying device, comprising a drying box for placement on a horizontal baffle of a household refrigerator or for fixed installation inside a household refrigerator. The drying box includes an observation window structure, a box base, and a metal side wall. The box base and the bottom of the side wall are directly or indirectly fixedly connected. The observation window structure includes a light-transmitting element, an inner fixing frame, and an outer fixing frame. The inner fixing frame and the outer fixing frame are detachably fixedly connected. The inner fixing frame and the outer fixing frame hold the light-transmitting element, and one of them is fixedly connected to the side of the side wall.

[0009] This invention facilitates the assembly of the drying box and reduces costs.

[0010] A further technical solution is provided where a connector is fixedly installed on the side edge of the inner or outer fixed frame; a side connecting wall is provided on the side wall of the box, and the side connecting wall has a through hole and a connecting hole communicating with the through hole; the connector can pass through the through hole, and the connector is directly opposite the connecting hole and abuts against the inner wall of the bottom connecting wall.

[0011] This technical solution facilitates the assembly of the drying box and reduces costs.

[0012] A further technical solution is that the drying box also includes a top frame; the top frame is detachably connected to the top of the side wall of the box, and the inner fixed frame and / or the outer fixed frame abut against the bottom surface of the top frame.

[0013] This technical solution ensures a secure connection between the observation window structure and the side wall of the enclosure.

[0014] A further technical solution includes a rack and a support frame in the drying box; the rack is provided with a drainage hole, the support frame is fixed to the bottom inner side of the side wall of the box, the bottom surface of the rack is placed on the support frame so that a gap is formed between the rack and the box base, and the side wall of the box is provided with a ventilation hole, which is directly opposite the gap between the rack and the box base in the height direction.

[0015] This technical solution ensures that the ventilation path of the drying chamber completely surrounds the meat being dried, and also allows the humidity inside the drying chamber to decrease rapidly, thereby ensuring a uniform drying effect on the meat.

[0016] A further technical solution involves extending the bottom of the side wall of the box inward to form a bottom connecting wall, with the bottom end face of the support frame abutting against the bottom connecting wall, and a bottom connecting post provided on the box base; screws pass through the support frame and the bottom connecting wall and are screwed into the bottom connecting post.

[0017] A further technical solution involves providing a top connecting lug on the side wall of the box, with screws sequentially passing through the top frame and screwed into the top connecting lug.

[0018] The screw tips in this technical solution all point downwards, making it easy to assemble the drying box using a screwdriver or similar tool.

[0019] A further technical solution is that the observation window structure also includes a flexible sealing gasket, which is placed between the light-transmitting element and the inner fixed frame or between the light-transmitting element and the outer fixed frame.

[0020] This technical solution can improve the overall strength of the observation window structure. Attached Figure Description

Detailed Implementation

[0035] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0036] As a specific embodiment, the dried meat making device based on a household refrigerator of this utility model is used for placement on the horizontal baffle of a household refrigerator. Therefore, the overall dimensions (i.e., external dimensions, that is, the smallest rectangular space in which the dried meat making device based on a household refrigerator can be placed) of the dried meat making device based on a household refrigerator are 23cm high, 32cm wide, and 32cm deep. It is easy to understand that one or more of these overall dimensions can be enlarged or reduced accordingly; for example, if the enlargement exceeds 30%, it may be difficult to use on the horizontal baffle of a household refrigerator; conversely, if the reduction exceeds 30%, it may increase the difficulty of temperature and humidity control and the difficulty of product manufacturing. Of course, the dried meat making device based on a household refrigerator can also be fixed inside the household refrigerator in other ways, such as by using hooks to fix it to the inside of the refrigerator door.

[0037] The present invention relates to a dried meat preparation device based on a household refrigerator, which includes at least a drying host 1, a support frame 2, and a drying box 3. The support frame 2 is detachably fixed to the top of the drying box 3, and the drying host 1 is placed on the support frame 2 such that its bottom end has a portion communicating with the inner cavity of the drying box 3.

[0038] The air-drying unit 1 includes a main unit carrier 11, an airflow device 12, and an electronic control device 18 mounted on the main unit carrier 11. The main unit carrier 11 is typically a plastic cover used to install the airflow device 12, water storage chamber 131, water delivery device 132, etc. (described later). The electronic control device 18 is a conventional device for implementing electronic control, such as a microcontroller or circuit board, which is usually electrically connected to a touch screen.

[0039] The airflow device 12 faces the bottom surface of the main unit carrier 11; a humidifier 13 and a temperature and humidity sensor 15 are provided on the bottom surface of the main unit carrier 11; the airflow device 12, the humidifier 13, and the temperature and humidity sensor 15 are electrically connected to the electronic control device 18. The airflow device 12 is a fan or the like, which, when in operation, causes air to enter from the air inlet 129 on the main unit carrier 11 and flow out from the air outlet (not shown in the attached figure) on the bottom surface of the main unit carrier 11, thereby blowing air into the inner cavity of the drying box 3 according to the control of the electronic control device 18. Similarly, the humidifier 13 can humidify the inner cavity of the drying box 3 according to the control of the electronic control device 18, and the temperature and humidity sensor 15 can detect the temperature and humidity of the inner cavity of the drying box 3 and transmit the temperature and humidity information to the electronic control device 18.

[0040] The dried meat preparation device based on a household refrigerator according to the present invention can accurately control the temperature and humidity inside the drying box 3, ensuring accurate drying conditions and improving drying quality.

[0041] The present invention provides a method for producing air-dried meat based on a household refrigerator, which includes the following steps:

[0042] The household refrigerator is set to have an internal ambient temperature of 2±2℃.

[0043] After placing the dried meat into the drying box 3, the drying box 3 is placed into the household refrigerator.

[0044] The electronic control device 18 is input with the type of dried meat being beef, pork, mutton, or game (i.e., meat other than beef, pork, and mutton);

[0045] The electronic control device 18 controls the humidification device 13 and also controls the airflow device 12 to operate at either low or medium speed, maintaining a humidity level of 80-85% inside the drying chamber 3. The low speed refers to a maximum rotation speed of 33%, and the medium speed refers to a maximum rotation speed of 50%. For example, the electronic control device 18 controls the rotation speed of the airflow device 12 using an eight-bit PWM signal (maximum pulse width 255). The low speed corresponds to a value of 85 (85 / 255=33%), and the medium speed corresponds to a value of 128. Both the low and medium speed values ​​can fluctuate by 30%.

[0046] The present invention provides a method for air-drying meat based on a household refrigerator, which can provide a better air-drying method for beef, pork, mutton, and game, and improve the air-drying quality.

[0047] As one specific implementation method, when the type of meat to be dried is beef, mutton, or game, when the temperature and humidity sensor 15 detects that the humidity is below 80%, the electronic control device 18 controls the humidification device 13 to start (so that the humidity inside the drying chamber 3 is 80-85%, but close to 80%), and the electronic control device 18 controls the airflow device 12 to run at medium speed; when the temperature and humidity sensor 15 detects that the humidity is above 85%, the electronic control device 18 controls the airflow device 12 to increase the airflow speed by 15-25%, for example, the increase in airflow speed corresponds to 50% of the eight-bit PWM signal, an increase of 19.6%. By selecting the optimal drying conditions according to the type of meat to be dried, the quality of the finished dried meat product can be improved.

[0048] As one specific implementation method, when the type of meat to be dried is pork, when the temperature and humidity sensor 15 detects that the humidity is below 85%, the electronic control device 18 controls the humidification device 13 to start (so that the humidity inside the drying chamber 3 is 80-85%, but close to 85%), and the electronic control device 18 controls the airflow device 12 to operate at a medium speed and a low speed; when the temperature and humidity sensor 15 detects that the humidity is above 85%, the electronic control device 18 controls the airflow device 12 to increase the airflow speed by 15-25%. By selecting the optimal drying conditions according to the type of meat to be dried, the quality of the finished dried meat product can be improved.

[0049] As one specific implementation, the bottom surface of the main unit carrier 11 is also provided with a sterilization device 14 electrically connected to the electronic control device 18; the sterilization device 14 is a UCV lamp bead, etc., which achieves sterilization through ultraviolet irradiation. Multiple sterilization devices 14 can be provided and arranged as needed.

[0050] When the type of dried meat is beef, the sterilization device 14 runs for 15 minutes every 12 hours;

[0051] When the type of dried meat is pork, the sterilization device 14 runs for 10 minutes every 24 hours.

[0052] When the type of dried meat is mutton, the sterilization device 14 runs for 12 minutes every 12 hours;

[0053] When the dried meat is wild game, the sterilization device 14 runs for 10 minutes every 12 hours.

[0054] Furthermore, regardless of the type of meat being dried, both the airflow device 12 and the humidification device 13 are stopped during the operation of the sterilization device 14. In other words, when the types of meat being dried are the four mentioned above, both the airflow device 12 and the humidification device 13 are stopped during the operation of the sterilization device 14. This enables effective UVC sterilization based on the type of meat being dried.

[0055] As one specific implementation, the main unit carrier 11 is provided with a water storage chamber 131 and a water delivery device 132 electrically connected to the electronic control device 18. The humidifying device 13 is connected to the water storage chamber 131 through the water delivery device 132. The water delivery device 132 is a conventional water pump, etc. The water storage chamber 131 is usually covered with a water storage chamber cover (not shown in the attached figure). The humidifying device 13 is a nozzle or ultrasonic atomizer, etc., which are existing technologies capable of outputting small water particles. The electronic control device 18 controls the water delivery device 132 to start, so that water in the water storage chamber 131 is added to the inner cavity of the drying box 3 through the humidifying device 13 to achieve humidification and increase humidity. Conversely, when the water delivery device 132 stops, the humidifying device 13 also stops humidifying, and the humidity in the inner cavity of the drying box 3 decreases due to the refrigerator environment.

[0056] As one specific implementation, the support frame 2 includes a positioning sidewall 22 and a supporting bottom wall 21 with a clearance hole 211. The drying unit 1 is placed on the supporting bottom wall 21, with its sidewalls close to or near the positioning sidewall 22. The clearance hole 211 faces the airflow device 12, the humidification device 13, and the temperature and humidity sensor 15. This ensures the stability of the position of the drying unit 1 relative to the drying box 3, thereby ensuring a stable drying effect on the meat. Typically, the positioning sidewall 22 is provided with a power inlet 223 facing the power interface 181 for wiring the power interface 181. The positioning sidewall 22 is also provided with a vent 229 facing the air inlet 129 to facilitate airflow through the airflow device 12.

[0057] As one of the specific implementation methods, such as Figure 6As shown, both sides of the positioning sidewall 22 are provided with a sidewall inclination angle 221, making the front of the positioning sidewall 22 lower than the back. The support frame 2 is provided with an operation port 222 at the front, and the front of the drying unit 1 is provided with a front handle 112 facing the operation port 222. After the drying box 3 is placed on the horizontal baffle of the household refrigerator represented by line 2, there are usually other horizontal baffles above the drying unit 1, which limits its height. By slightly tilting the front of the drying unit 1, the drying unit 1 can be pulled out from the support frame 2 in a relatively small space, which facilitates subsequent operations such as adding water to the water storage chamber 131.

[0058] As one specific implementation, the air dryer 1 includes a position sensor 16 electrically connected to the electronic control device 18. The position sensor 16 is used to detect the position of the air dryer 1 relative to the support frame 2. The air dryer 1 can only start operating after it is placed on the support frame 2, thus preventing the air dryer 1 from running idle.

[0059] As one specific implementation, the position sensor 16 is a micro switch 161; the air dryer 1 also includes a trigger 162, and the main unit carrier 11 is provided with a trigger slot 163; the trigger 162 is embedded in the trigger 162 and can move up and down along the trigger slot 163, the bottom end surface of the trigger 162 is flush with the bottom end surface of the main unit carrier 11 and has a downward movement tendency. For example, the trigger 162 is fitted with a spring (not shown in the figure), and the elastic force of the spring makes the trigger 162 have a downward movement tendency. The support bottom wall 21 is provided with a trigger protrusion 212 facing the trigger 162. After the air dryer 1 is placed on the support frame 2, the trigger protrusion 212 abuts against the trigger 162, causing the trigger 162 to move upward and trigger the micro switch 161. At this time, the air dryer 1 can start running, which can prevent the air dryer 1 from running dry, and the bottom end surface of the air dryer 1 is roughly a plane, which makes it easy to place the air dryer 1 on a table or other place for operations such as adding water.

[0060] As one specific implementation, power interfaces 181 are provided on both sides of the main unit carrier 11. The power interfaces 181 are directly or indirectly electrically connected to the electronic control device 18. The power interfaces 181 are DC round hole interfaces or USB interfaces (such as microUSB, TYPE-CUSB, etc.) and are connected to plugs 182. Although the air dryer 1 can be connected to a power bank such as a lithium battery through the power interface 181, the power supply efficiency of power banks such as lithium batteries is low due to the low temperature inside a household refrigerator and the low power supply efficiency in low-temperature environments. Therefore, the air dryer 1 needs to be powered by a power cord. When one power interface 181 is connected to a DC power supply head or a USB cable, the other power interface 181 is blocked by the plug 182. This allows for convenient power supply to the air dryer 1 while ensuring that the air dryer 1 remains relatively dry and that the circuit is safe.

[0061] The drying box 3 includes an observation window structure 31, a box base 34, and a metal side wall 32. The bottom of the box base 34 and the side wall 32 are directly or indirectly fixedly connected. It is easy to understand that the side wall 32 is U-shaped when viewed from above. The observation window structure 31, the box base 34, and the side wall 32 together form a box shape with an open top, so that the drying box 3 has an inner cavity for placing the dried meat.

[0062] The observation window structure 31 includes a light-transmitting element 311, an inner fixing frame 312, and an outer fixing frame 313. The inner fixing frame 312 and the outer fixing frame 313 are detachably fixedly connected (e.g., by snap-fit ​​connection, and / or by screw connection). The inner fixing frame 312 and the outer fixing frame 313 clamp the light-transmitting element 311, and one of them is fixedly connected to the side of the side wall 32 of the box. The light-transmitting element 311 is made of glass, acrylic sheet, etc., and is transparent, so the state of the dried meat inside the drying box 3 can be viewed through the light-transmitting element 311. The inner fixing frame 312, the outer fixing frame 313, the top frame 33 (described later), the box base 34 (described later), and the support frame 35 (described later) are usually made of plastic.

[0063] In the above structure, the observation window structure 31 is assembled into one piece and then fixedly connected to the side wall 32 of the box, which facilitates the assembly of the drying box 3 and can reduce costs.

[0064] As one of the specific implementation methods, such as Figure 11 As shown, a connector 315 is fixedly installed on the side edge of the inner fixing frame 312 or the outer fixing frame 313; a side connecting wall 321 is provided on the side wall of the box side wall 32, the side connecting wall 321 has a through hole 322 and a connecting hole 323 communicating with the through hole 322; the connector 315 can pass through the through hole 322, the connector 315 is directly opposite the connecting hole 323 and abuts against the inner wall of the bottom connecting wall 325. It is easy to understand that the connector 315, the inner fixing frame 312 or the outer fixing frame 313 are located at the height of the connecting hole 323 in the height direction, and the two clamp the side connecting wall 321, so that the observation window structure 31 is detachably and fixedly connected to the box side wall 32. When assembling the observation window structure 31, first move the observation window structure 31 toward the side connecting wall 321, so that the connector 315 passes through the through hole 322. Then, move the side connecting wall 321 downward until the connector 315, the inner fixing frame 312, or the outer fixing frame 313 clamp the side connecting wall 321. It can be seen that the observation window structure 31 can be fixedly connected to the side wall 32 of the drying box without screws or other fasteners, which facilitates the assembly of the drying box 3 and reduces costs.

[0065] As one specific implementation, the drying box 3 also includes a top frame 33; the top frame 33 is detachably connected to the top end of the side wall 32 of the box, and the inner fixing frame 312 and / or the outer fixing frame 313 abut against the bottom end face of the top frame 33. The top frame 33 abuts against the inner fixing frame 312 and / or the outer fixing frame 313, restricting the upward movement of the observation window structure 31, which can ensure that the observation window structure 31 is firmly fixed to the side wall 32 of the box.

[0066] As one specific implementation, the drying box 3 also includes a rack 5 and a support frame 35. The rack 5 is provided with a drainage hole (not shown in the attached drawing). The support frame 35 is fixed to the inner bottom of the side wall 32 of the box. The bottom surface of the rack 5 rests on the support frame 35, creating a gap between the rack 5 and the box base 34. The side wall 32 of the box is provided with a ventilation hole 329, which is directly opposite the gap between the rack 5 and the box base 34 in the height direction. The gap between the rack 5 and the box base 34 is used to collect water dripping from the dried meat. For easy cleaning, a water collection tray 4 is also provided in the gap between the rack 5 and the box base 34. One end of the water collection tray 4 protrudes from below the observation window structure 31, so that the water collection tray 4 can be inserted and removed for cleaning. The airflow device 12 blows air downwards from the bottom surface of the main carrier 11. The air flows through the dried meat, passes through the gap between the rack 5 and the box base 34, and flows out from the ventilation hole 329. It can ensure that the ventilation path of the drying box 3 completely surrounds the meat being dried, and can also reduce the humidity inside the drying box 3 quickly, thereby ensuring a uniform drying effect on the meat being dried.

[0067] As one specific implementation method, the bottom end of the box side wall 32 extends inward to form a bottom connecting wall 325, the bottom end face of the support frame 35 abuts against the bottom connecting wall 325, and the box base 34 is provided with a bottom connecting post 349; screws (not shown in the attached figure) pass through the support frame 35 and the bottom connecting wall 325 and are screwed into the bottom connecting post 349, so that the box base 34 and the bottom end of the box side wall 32 are indirectly fixedly connected.

[0068] As one specific implementation, the side wall 32 of the box is provided with a top connecting lug 326. Screws (not shown in the attached diagram) are screwed into the top connecting lug 326 through the top frame 33, making the top frame 33 detachably connected to the top of the side wall 32. When assembling the drying box 3, first rotate the screws so that they pass through the support frame 35 and the bottom connecting wall 325 and are screwed into the bottom connecting post 349. Then install the observation window structure 31. Finally, rotate the screws so that they pass through the top frame 33 and are screwed into the top connecting lug 326. During this process, the tips of the screws are all facing downwards, which facilitates the assembly of the drying box 3 with a screwdriver or similar tool.

[0069] As one specific implementation, the observation window structure 31 also includes a flexible sealing gasket 314. For example, the sealing gasket 314 is made of silicone, rubber, or the like and is flexible. The sealing gasket 314 is disposed between the light-transmitting element 311 and the inner fixing frame 312 or between the light-transmitting element 311 and the outer fixing frame 313. This can improve the overall strength of the observation window structure 31.
