[0002] With the continuous improvement of people's living standards and the continuous progress of society, the taste and requirements of life in Western countries and our country are also constantly improving. In particular, the unique eating habits of Western countries have a special liking for aged beef and have a unique pursuit. People generally do not directly cook and eat fresh beef, but they have to go through a unique processing method before cooking and eating. Among them, beef processed by dry-aging technology is the most popular and favored food. Beef aging originated from the early European and American nobles and indigenous residents who placed the uneaten meat in cellars and cold cellars to dry in the shade in order to preserve the prey after hunting. Due to the corresponding humidity and temperature, the original dry-aging process was achieved. After a period of time, the residents accidentally discovered that the meat flavor was better after aging, so the dry-aging technology was born.

[0003] CN220823921U discloses a household beef air-drying machine, comprising an aging box, and further comprising: an aging box upper cover, the aging box upper cover is arranged at the top of the aging box, a plurality of mounting grooves are arranged on the surface of the aging box upper cover, and a bottom cover is also installed at the bottom of the aging box; an electronic scale assembly, the electronic scale assembly is installed on the upper surface of the aging box upper cover, and is used to measure the weight of the beef; an aging rack one, the aging rack one is arranged inside the aging box, and fresh beef is placed on the aging rack one; a UCV lamp, a plurality of UCV lamps are installed, and the UCV lamps are evenly arranged at the bottom end of the electronic scale assembly, so as to sterilize and disinfect the fresh beef placed on the aging rack one; wherein a fan is also installed at the bottom end of the electronic scale assembly, for blowing airflow to the surface of the fresh beef at a constant wind speed; in addition, the beef air-drying machine is placed in a refrigerator as a whole, and the temperature and humidity inside the refrigerator are controlled by the refrigerator settings.

[0006] The household beef air-drying machine disclosed in CN220823921U does not disclose the materials used to make the air-drying box. However, in order to make the temperature in the air-drying box consistent with the temperature in the refrigerator as soon as possible, the air-drying box needs to be made of high thermal conductivity materials such as stainless steel as much as possible. However, the air-drying box made of high thermal conductivity materials such as stainless steel is not light-transmissive, so setting an observation window on the air-drying box requires assembling parts of different materials, resulting in a complicated assembly process and high production cost.

DETAILED DESCRIPTION

[0050] The specific implementation of the present invention will be described below with reference to the accompanying drawings.

[0051] As a specific embodiment, the air-dried meat preparation device based on a household refrigerator of the embodiment of the present invention is used to be placed on the horizontal baffle of a household refrigerator. Therefore, the overall size of the air-dried meat preparation device based on a household refrigerator (i.e., the overall size, that is, the size of the smallest rectangular space in which the air-dried meat preparation device based on a household refrigerator can be placed) is 23 cm in height, 32 cm in width, and 32 cm in depth. It is easy to understand that one or more of the overall dimensions can be enlarged or reduced accordingly; for example, if the enlarged size exceeds 30%, it may make it difficult to use on the horizontal baffle of a household refrigerator; for example, if the reduced size exceeds 30%, it may increase the difficulty of temperature and humidity control and the difficulty of product manufacturing. Of course, the air-dried meat preparation device based on a household refrigerator can also be fixed in a household refrigerator for use in other ways, such as being fixed to the inside of the refrigerator door by a hook.

[0052] The air-dried meat preparation device based on a household refrigerator of an embodiment of the present invention comprises at least an air-drying main unit 1, a support frame 2 and an air-drying box 3, wherein the support frame 2 is detachably fixedly connected to the top of the air-drying box 3, and the air-drying main unit 1 is placed on the support frame 2 so that there is a portion on its bottom end surface that is connected to the inner cavity of the air-drying box 3.

[0053] The air-drying host 1 includes a host carrier 11, an air flow device 12, and an electric control device 18 disposed on the host carrier 11. The host carrier 11 is usually a plastic cover for mounting the air flow device 12, a water storage chamber 131, a water delivery device 132, etc. The electric control device 18 is a conventional device for realizing electric control, such as a single-chip microcomputer or a circuit board, etc., and the single-chip microcomputer or the circuit board is usually electrically connected to a touch screen.

[0054] The air flow device 12 faces the bottom end surface of the host carrier 11; the bottom end surface of the host carrier 11 is provided with a humidifying device 13 and a temperature and humidity sensor 15; the air flow device 12, the humidifying device 13, and the temperature and humidity sensor 15 are electrically connected to the electronic control device 18 respectively. The air flow device 12 is a fan, etc., which allows air to enter from the air inlet 129 on the host carrier 11 and flow out from the air outlet (not shown in the drawing) on ​​the bottom end surface of the host carrier 11 after operation, so that air can be blown into the inner cavity of the air drying box 3 according to the control of the electronic control device 18. Similarly, the humidifying device 13 can humidify the inner cavity of the air 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 air drying box 3, and transmit the temperature and humidity information to the electronic control device 18.

[0055] The air-dried meat preparation device based on a household refrigerator of the embodiment of the present invention can accurately control the temperature and humidity in the air-drying box 3, ensure accurate air-drying conditions, and improve the air-drying quality.

[0056] The method for preparing air-dried meat based on a household refrigerator according to an embodiment of the present invention comprises the following steps:

[0057] Setting the household refrigerator so that its internal ambient temperature is 2±2°C;

[0058] After placing the air-dried meat into the air-drying box 3, the air-drying box 3 is placed into the household refrigerator;

[0059] Inputting the type of meat to be dried into the electronic control device 18 is one of beef, pork, mutton, and game (i.e., meat other than beef, pork, and mutton);

[0060] The electronic control device 18 controls the humidifying device 13, and the electronic control device 18 controls the wind speed of the air flow device 12 to be one of low speed and medium speed, so that the humidity in the air drying box 3 is 80-85%; wherein the low speed refers to 33% of the maximum speed; the medium speed refers to 50% of the maximum speed; for example, the electronic control device 18 controls the speed of the air flow device 12 through an eight-bit PMW signal (the maximum value of the pulse signal width is 255), the low speed corresponds to a value of 85 (85 / 255=33%), and the medium speed corresponds to a value of 128. The low speed corresponding value and the medium speed corresponding value can both fluctuate by 30%.

[0061] The air-dried meat preparation method based on a household refrigerator of the embodiment of the present invention can provide a better air-drying method for beef, pork, mutton and game, and improve the air-drying quality.

[0062] As one of the specific implementations, when the air-dried meat is beef, mutton or game, when the temperature and humidity sensor 15 detects that the humidity is lower than 80%, the electronic control device 18 controls the humidification device 13 to start (so that the humidity in the air-drying box 3 is 80-85% but close to 80%) and the electronic control device 18 controls the wind speed of the air flow device 12 to be medium speed; when the temperature and humidity sensor 15 detects that the humidity is higher than 85%, the electronic control device 18 controls the wind speed of the air flow device 12 to increase by 15-25%, for example, the degree of wind speed increase corresponds to 50 of the eight-bit PMW signal, which is an increase of 19.6%. Selecting the best air-drying conditions according to the type of air-dried meat can improve the quality of the finished air-dried meat.

[0063] As one of the specific implementations, when the air-dried meat is pork, when the temperature and humidity sensor 15 detects that the humidity is lower than 85%, the electronic control device 18 controls the humidification device 13 to start (so that the humidity in the air-drying box 3 is 80-85% but close to 85%) and the electronic control device 18 controls the wind speed of the air flow device 12 to be medium speed; when the temperature and humidity sensor 15 detects that the humidity is higher than 85%, the electronic control device 18 controls the wind speed of the air flow device 12 to increase by 15-25%. Selecting the best air-drying conditions according to the type of air-dried meat can improve the quality of the finished air-dried meat.

[0064] As one of the specific implementations, the bottom surface of the host carrier 11 is also provided with a sterilization device 14 electrically connected to the electric control device 18; the sterilization device 14 is a UCV lamp bead, etc., which sterilizes by ultraviolet irradiation. Multiple sterilization devices 14 can be provided and arranged according to needs.

[0065] When the air-dried meat is beef, the sterilizing device 14 operates for 15 minutes every 12 hours;

[0066] When the air-dried meat is pork, the sterilizing device 14 operates for 10 minutes every 24 hours;

[0067] When the air-dried meat is mutton, the sterilizing device 14 operates for 12 minutes every 12 hours;

[0068] When the air-dried meat is game, the sterilizing device 14 operates for 10 minutes every 12 hours;

[0069] Regardless of the type of meat being dried, the air flow device 12 and the humidification device 13 are stopped during the operation of the sterilization device 14. In other words, when the type of meat being dried is the above four types, the air flow device 12 and the humidification device 13 are stopped during the start-up of the sterilization device 14. Effective UVC sterilization can be achieved according to the type of meat being dried.

[0070] As one of the specific implementations, the host carrier 11 is provided with a water storage chamber 131 and a water delivery device 132 electrically connected to the electronic control device 18, and 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 or the like. The water storage chamber 131 is usually covered with a water storage chamber cover (not shown in the accompanying drawings). The humidifying device 13 is a nozzle or an ultrasonic atomizer, etc., which is an existing technology capable of outputting smaller particles of water. The electronic control device 18 controls the water delivery device 132 to start, so that the water in the water storage chamber 131 is added from the humidifying device 13 to the inner cavity of the air drying box 3 to achieve humidification and increase the humidity. Conversely, after the water delivery device 132 stops, the humidifying device 13 also stops humidifying, and the humidity of the inner cavity of the air drying box 3 decreases due to the refrigerator environment.

[0071] As one of the specific implementations, the support frame 2 includes a positioning side wall 22 and a supporting bottom wall 21 with a clearance hole 211. The air-drying main unit 1 is placed on the supporting bottom wall 21 and its side wall is in contact with or close to the positioning side wall 22. The clearance hole 211 faces the air flow device 12, the humidifying device 13 and the temperature and humidity sensor 15. It can ensure that the position of the air-drying main unit 1 relative to the air-drying box 3 is stable, thereby ensuring the stable air-drying effect of the air-dried meat. Usually, the positioning side wall 22 is provided with a power connection port 223 facing the power interface 181 to facilitate the connection of the power interface 181. The positioning side wall 22 is provided with a vent 229 facing the air inlet 129 to facilitate the air flow device 12 to form an air flow passage.

[0072] As one of the specific implementations, Figure 6 As shown, the parts on both sides of the positioning side wall 22 are provided with side wall inclination angles 221 so that the parts on both sides of the positioning side wall 22 are low in front and high in the back. An operation port 222 is provided in the front of the support frame 2, and a front handle 112 facing the operation port 222 is provided in the front of the air-drying main unit 1. After the air-drying box 3 is placed on the horizontal baffle of a household refrigerator represented by line 2 LINE2, there are usually other horizontal baffles above the air-drying main unit 1 and the height is limited. After the front end of the air-drying main unit 1 is slightly tilted, the air-drying main unit 1 can be pulled out from the support frame 2 in a space of a smaller height, which is convenient for subsequent operations such as adding water to the water storage chamber 131.

[0073] As one of the specific implementations, the air-drying main unit 1 includes a position sensor 16 electrically connected to the electric control device 18, and the position sensor 16 is used to detect the position of the air-drying main unit 1 relative to the support frame 2. Only after the air-drying main unit 1 is placed on the support frame 2, the air-drying main unit 1 can be started and operated, which can prevent the air-drying main unit 1 from idling.

[0074] As one of the specific implementations, the position sensor 16 is a micro switch 161; the air-drying host 1 also includes a trigger 162, and the host carrier 11 is provided with a trigger slot 163; the trigger 162 is embedded in the trigger 162 and can be lifted and lowered along the trigger slot 163, and the bottom end surface of the trigger 162 is flush with the bottom end surface of the host carrier 11 and has a tendency to move downward. For example, the trigger 162 is provided with a spring (not shown in the accompanying drawings), and the elastic force of the spring makes the trigger 162 have a tendency to move downward. The supporting bottom wall 21 is provided with a trigger protrusion 212 facing the trigger 162. After the air-drying host 1 is placed on the support frame 2, the trigger protrusion 212 abuts against the trigger 162 so that the trigger 162 moves upward and triggers the micro switch 161. At this time, the air-drying host 1 can start to run, which can prevent the air-drying host 1 from idling, and the bottom end surface of the air-drying host 1 is roughly a plane, which is convenient for placing the air-drying host 1 on a desktop or the like for operations such as adding water.

[0075] As one of the specific implementations, power interfaces 181 are provided on both sides of the host carrier 11. The power interfaces 181 are electrically connected to the electronic control device 18 directly or indirectly. 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-drying host 1 can be connected to a mobile power source such as a lithium battery through the power interface 181, the temperature in a household refrigerator is relatively low and the power supply efficiency of mobile power sources such as lithium batteries is relatively low in a low temperature environment. Therefore, the air-drying host 1 needs to be powered by wires. 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, which can conveniently supply power to the air-drying host 1 while ensuring that the air-drying host 1 is relatively dry and the circuit is safe.

[0076] The air drying box 3 includes an observation window structure 31, a box base 34, and a metal box side wall 32, and the box base 34 is directly or indirectly fixedly connected to the bottom end of the box side wall 32. It is easy to understand that the box side wall 32 is a U-shape as a whole when viewed from above, and the observation window structure 31, the box base 34, and the box side wall 32 are surrounded to form a box shape with an open top, so that the air drying box 3 has an inner cavity for placing the air-dried meat.

[0077] The observation window structure 31 includes a light-transmitting member 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., snap-fitted and / or screwed), the inner fixing frame 312 and the outer fixing frame 313 clamp the light-transmitting member 311, and one of the two is fixedly connected to the side of the box side wall 32. The light-transmitting member 311 is glass, acrylic plate, etc. and has light transmittance, so the state of the air-dried meat in the air-drying box 3 can be viewed through the light-transmitting member 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.

[0078] In the above structure, after the observation window structure 31 is assembled into one body, the observation window structure 31 is fixedly connected to the box side wall 32, which is convenient for assembling the air-drying box 3 and can reduce costs.

[0079] As one of the specific implementations, Fig.11As shown, a connector 315 is fixedly provided 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, and the side connecting wall 321 is provided with a through hole 322 and a connecting hole 323 connected to the through hole 322; the connector 315 can pass through the through hole 322, and the connector 315 is directly opposite to 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 fixedly connected to the box side wall 32 in a detachable manner. When assembling the observation window structure 31, first move the observation window structure 31 toward the side connecting wall 321 so that the connecting body 315 passes through the through hole 322, and then move the side connecting wall 321 downward until the connecting body 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 box side wall 32 without fasteners such as screws, which facilitates the assembly of the air-drying box 3 and can reduce costs.

[0080] As one of the specific implementations, the air drying box 3 further includes a top frame 33; the top frame 33 is detachably connected to the top of the box side wall 32, and the inner fixing frame 312 and / or the outer fixing frame 313 abut against the bottom end surface of the top frame 33. The top frame 33 abuts against the inner fixing frame 312 and / or the outer fixing frame 313 to limit the upward movement of the observation window structure 31, thereby ensuring that the observation window structure 31 is firmly fixedly connected to the box side wall 32.

[0081] As one of the specific embodiments, the air drying box 3 further includes a carrier 5 and a support frame 35; the carrier 5 is provided with a water leakage hole (not shown in the drawings), the support frame 35 is fixed to the inner side of the bottom end of the box side wall 32, the bottom end surface of the carrier 5 is placed on the support frame 35 so that a gap is formed between the carrier 5 and the box base 34, and the box side wall 32 is provided with a ventilation hole 329, and the ventilation hole 329 is directly opposite to the gap between the carrier 5 and the box base 34 in the height direction. The gap between the carrier 5 and the box base 34 is used to accommodate water dripped from the air-dried meat. For the convenience of cleaning, a water receiving tray 4 is also provided in the gap between the carrier 5 and the box base 34, and one end of the water receiving tray 4 is exposed from the bottom of the observation window structure 31, so that the water receiving tray 4 can be inserted, pulled out and cleaned. The air flow device 12 blows air downward from the bottom end surface of the main body carrier 11, and the air flows through the air-dried meat and then passes through the gap between the carrier 5 and the box base 34, and flows out from the ventilation hole 329. It can ensure that the ventilation path of the air-drying box 3 completely surrounds the air-dried meat, and the humidity in the air-drying box 3 can be reduced relatively quickly, thereby ensuring a uniform air-drying effect on the air-dried meat.

[0082] As one of the specific implementations, the bottom end of the box side wall 32 extends inward to form a bottom connecting wall 325, the bottom end surface of the support frame 35 abuts against the bottom connecting wall 325, and the box base 34 is provided with a bottom connecting column 349; a screw (not shown in the drawings) passes through the support frame 35 and the bottom connecting wall 325 and is screwed into the bottom connecting column 349, so that the box base 34 is indirectly fixedly connected to the bottom end of the box side wall 32.

[0083] As one of the specific implementations, the box side wall 32 is provided with a top connecting ear 326, and screws (not shown in the drawings) are sequentially passed through the top frame 33 and screwed into the top connecting ear 326, so that the top frame 33 is detachably connected to the top of the box side wall 32. When assembling the air drying box 3, first rotate the screw so that the screw passes through the support frame 35 and the bottom connecting wall 325 and is screwed into the bottom connecting column 349, then install the observation window structure 31, and finally rotate the screw so that the screw passes through the top frame 33 and is screwed into the top connecting ear 326 in sequence. During this process, the tips of the screws are all facing downward, which is convenient for assembling the air drying box 3 by a screwdriver or the like.

[0084] As one of the specific implementations, the observation window structure 31 further includes a flexible sealing pad 314, for example, the sealing pad 314 is made of silicone, rubber, etc. and is flexible, and the sealing pad 314 is arranged between the light-transmitting member 311 and the inner fixing frame 312 or between the light-transmitting member 311 and the outer fixing frame 313. The overall strength of the observation window structure 31 can be improved.
