Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and in particular to a refrigerator for storing Chinese medicinal herbs and a control method thereof. Background Technology

[0002] In daily life, in order to extend the shelf life of Chinese medicinal materials and prevent them from spoiling, they are generally stored in the refrigerator at low temperatures.

[0003] The main reasons for the deterioration of Chinese medicinal herbs include oxidation, insect infestation, mold, and moisture absorption. People generally use the low-temperature environment of refrigerators to inhibit the oxidation and mold growth of Chinese medicinal herbs, but the following problems still exist even under low-temperature conditions:

[0004] 1. In low-temperature environments, the volatile components in Chinese medicinal herbs will still oxidize.

[0005] 2. Some molds can also grow at 5℃.

[0006] 3. Frequent opening and closing of the refrigerator when handling Chinese medicinal herbs will introduce moisture, causing the herbs to absorb moisture and become damp.

[0007] 4. Although some refrigerators are equipped with vacuum zones for storing Chinese medicinal herbs, which can prevent oxidation and moisture absorption to a certain extent, Chinese medicinal herbs that have been infected by insects, mold, or have absorbed moisture will still slowly deteriorate during storage. Ingesting spoiled Chinese medicinal herbs can cause harm to the human body. Summary of the Invention

[0017] Furthermore, the drawer is provided with a perforated support plate located between the two microwave circuit boards.

[0018] Furthermore, the pumping assembly includes a vacuum pump, a shut-off valve, and a vacuum pump pipeline;

[0019] The vacuum pump's suction port is connected to one end of the vacuum pump pipe, and the other end of the vacuum pump pipe is connected to the storage room, and the other end of the vacuum pump pipe communicates with the space inside the storage room.

[0020] The vacuum pump pipeline is equipped with a shut-off valve;

[0021] Both the vacuum pump and the shut-off valve are electrically connected to the touchscreen.

[0022] Furthermore, the refrigerator body has at least one storage compartment, each drawer has a handle, and the side wall of the drawer with the handle is also equipped with a touch screen.

[0023] This invention also proposes a control method for the above-mentioned refrigerator for storing Chinese medicinal materials, comprising the following steps:

[0024] S1: After the Chinese medicinal materials are placed in the storage room, the vacuum pump is started to create a vacuum environment in the storage room and reduce the humidity in the storage room;

[0025] S2: When the humidity in the storage room is less than the threshold humidity, detect the humidity change value △RH in the storage room within a preset time.

[0026] S3: Based on a pre-set control relationship, obtain and execute the storage method corresponding to the humidity change value △RH;

[0027] S4: After the storage method is completed, start the vacuum pump to make the humidity in the storage room less than the threshold humidity.

[0028] Furthermore, the threshold humidity in steps S1 and S4 is 30%;

[0029] The preset time for step S2 is 30 minutes.

[0030] Furthermore, the humidity change value ΔRH in step S2 includes a first threshold interval, a second threshold interval, and a third threshold interval;

[0031] Furthermore, when the humidity change value △RH is within the first threshold range, the storage method includes setting the drying time to 20 minutes and adjusting the power of the microwave circuit board according to the type of Chinese medicinal material;

[0032] When the humidity change value △RH is within the second threshold range, the storage method includes setting the drying time to 40 minutes and adjusting the power of the microwave circuit board according to the type of Chinese medicinal material.

[0033] When the humidity change value △RH is within the third threshold range, the storage method includes setting the drying time to 60 minutes and adjusting the power of the microwave circuit board according to the type of Chinese medicinal material.

[0060] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Therefore, a feature pointed out in this specification is used to illustrate one feature of one embodiment of the invention, and does not imply that every embodiment of the invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0061] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0062] This invention includes the refrigeration module, freezer compartment, and refrigerator compartment that are present in existing refrigerators.

[0063] As one embodiment, refer to the appendix Figure 1-4 The present invention proposes a refrigerator for storing Chinese medicinal materials, including a refrigerator body 10 and a storage compartment 20 located inside the refrigerator body 10. The refrigerator body 10 is provided with an air extraction component 30, which communicates with the storage compartment 20.

[0064] The storage chamber 20 is sealed, and a heating component 40 and a humidity sensor 50 are provided inside the storage chamber 20. A touch screen 60 is provided on one side wall of the storage chamber 20 in the outward pulling direction.

[0065] The touch screen 60 is electrically connected to the air extraction assembly 30, the heating assembly 40, and the humidity sensor 50, respectively.

[0066] The sealed storage chamber 20 is used to store Chinese medicinal herbs, preventing outside air from entering and causing spoilage. The air extraction assembly 30 is used to extract air from the storage chamber 20 to maintain a vacuum environment. The heating assembly 40 is used to heat, dry, sterilize, and kill insects in the storage chamber 20. The humidity sensor 50 is used to detect the humidity in the storage chamber 20, and the detected humidity can be displayed on the touch screen 60. The touch screen 60 contains a control center, which controls the operation of the corresponding components when the user selects a storage method for the Chinese medicinal herbs.

[0067] After the user places the Chinese medicinal herbs into the storage chamber 20 and seals it, the user presses the open button on the touch screen 60. At this time, the control center will activate the vacuum component 30 to extract the air from the storage chamber 20, creating a vacuum environment. Then, when the humidity sensor 50 detects that the humidity in the storage chamber 20 is less than 30%, the humidity sensor 50 will send a stop electrical signal to the control center. Upon receiving the signal, the control center will shut down the vacuum component 30. The user can then view the humidity change in the storage chamber 20 on the touch screen 60. Based on this humidity change, the user can select the corresponding storage method for the Chinese medicinal herbs on the touch screen 60 (this storage method includes the working time of the heating component 40 or the drying time). The control center will then control the heating component 40 to operate, heating and drying the Chinese medicinal herbs in the storage chamber 20. During the drying process, the Chinese medicinal herbs can also be sterilized and killed. After the heating component 40 completes its operation, the control center restarts the vacuum component 30 to extract air from the storage chamber 20 until the humidity sensor 50 detects that the humidity in the storage chamber 20 is less than 30% (of course, if the humidity sensor 50 detects that the humidity in the storage chamber 20 is less than 30% after the heating component 40 has completed its operation, there is no need to restart the vacuum component 30). The humidity sensor 50 will then send a stop signal to the control center, which will then shut down the vacuum component 30. When the storage chamber 20 is reopened to retrieve medicinal herbs, if no new herbs are being added, simply maintaining a vacuum environment in the storage chamber 20 is sufficient. If new herbs are being added, the above operation must be repeated to heat, dry, sterilize, and kill insects in the new herbs.

[0068] When Chinese medicinal materials are placed in the storage chamber 20, the present invention can create a vacuum environment for the Chinese medicinal materials through the vacuum component 30. This can prevent the Chinese medicinal materials from oxidizing and absorbing moisture, and the volatile components in the Chinese medicinal materials are not easily oxidized in a vacuum environment.

[0069] Furthermore, the present invention can also heat and dry Chinese medicinal materials in a vacuum environment through the heating component 40. Even if the Chinese medicinal materials placed in the storage room 20 are infected with insects, mold, and moisture, the present invention can still heat and dry them and sterilize and kill insects to prevent the Chinese medicinal materials from deteriorating during storage.

[0070] Since the storage compartment 20 of the present invention is located inside the refrigerator body 10, it still has a refrigeration function, and the storage compartment 20 is in a low-temperature vacuum environment when it is working.

[0071] Among them, refer to the appendix Figure 1-3 The storage compartment 20 includes a shell 201 and a drawer 202.

[0072] The heating assembly 40 includes at least one microwave plate 401.

[0073] Drawer 202 can be inserted into housing 201 and slidably connected to it, so that drawer 202 can be opened or closed relative to housing 201; when drawer 202 is completely closed relative to housing 201, storage compartment 20 is in a sealed state to prevent outside air from entering storage compartment 20.

[0074] Among them, refer to the appendix Figure 1-2 The microwave circuit boards 401 are all located on the inner sidewall of the housing 201, and the microwave circuit boards 401 are all electrically connected to the touch screen 60.

[0075] When the heating component 40 is activated, the microwave board 401 emits microwaves, which are electromagnetic waves with frequencies between 300MHz and 300GHz. Because the water molecules in the Chinese medicinal materials (also referred to as the heated medium) are polar molecules, their polar orientation changes with the change of the external electric field under the action of a rapidly changing high-frequency electromagnetic field (i.e., microwaves). This causes the water molecules to spin, and the field energy of the microwave field is converted into heat energy within the Chinese medicinal materials, raising the internal temperature and producing a series of physicochemical processes such as thermochemical reaction, thereby achieving the purpose of microwave heating and drying.

[0076] Among them, refer to the appendix Figure 2 Preferably, there are two microwave circuit boards 401, which are arranged opposite to each other and located on the inner top wall and inner bottom wall of the housing 201, respectively. This can improve the effect of the microwave circuit boards 401 on heating, drying and sterilizing the Chinese medicinal materials placed in the storage chamber 20.

[0077] The drawer 202 is provided with a hollowed-out support plate (not shown, same throughout). The support plate is located between the two microwave circuit boards 401 and is used to support Chinese medicinal materials. This allows for better transmission of microwaves and better heating, drying, sterilization, and insect control of the Chinese medicinal materials placed in the storage room 20.

[0078] The vacuum pump assembly 30 includes a vacuum pump 301, a shut-off valve 302, and a vacuum pump pipe 303.

[0079] The vacuum pump 301 has its air extraction port connected to one end of the vacuum pump pipe 303, and the other end of the vacuum pump pipe 303 is connected to the storage chamber 20, and the other end of the vacuum pump pipe 303 communicates with the space inside the storage chamber 20.

[0080] The vacuum pump pipeline 303 is equipped with a shut-off valve 302, which can cut off the vacuum pump pipeline 303, preventing air from flowing inside the vacuum pump pipeline 303.

[0081] The vacuum pump 301 and the shut-off valve 302 are electrically connected to the touch screen 60.

[0082] When the vacuum pump 30 is started, the control center first starts the vacuum pump 301 and then opens the shut-off valve 302, so that the vacuum pump 301 can smoothly remove the air from the storage chamber 20, so that the storage chamber 20 is in a vacuum environment and the humidity inside the storage chamber 20 is reduced. When the vacuum pump 30 is turned off, the control center turns off the shut-off valve 302 and the vacuum pump 301 in sequence, which can prevent the humidity inside the storage chamber 20 from being too low.

[0083] The refrigerator body 10 includes at least one storage compartment 20, and each drawer 202 is equipped with a handle 203. A touchscreen 60 is also provided on the side wall of the drawer 202 with the handle 203. This allows users to conveniently place medicinal herbs into the drawer 202 and close it relative to the housing 201, and then perform the next step on the touchscreen 60.

[0084] The refrigerator body 10 can also be equipped with two storage compartments 20 (see attached). Figure 4 ).

[0085] See attached document Figure 5 The present invention also proposes a control method for a traditional Chinese medicine storage refrigerator as described above, comprising the following steps:

[0086] S1: After the Chinese medicinal materials are placed in the storage room 20, the vacuum pump 301 is started to put the storage room 20 into a vacuum environment and reduce the humidity inside the storage room 20;

[0087] S2: When the humidity in the storage room 20 is less than the threshold humidity, detect the humidity change value △RH of the storage room 20 within a preset time.

[0088] S3: Based on a pre-set control relationship, obtain and execute the storage method corresponding to the humidity change value △RH;

[0089] S4: After the storage method is completed, start the vacuum pump (301) to make the humidity in the storage room 20 less than the threshold humidity.

[0090] The threshold humidity in steps S1 and S4 is 30%.

[0091] The preset time for step S2 is 30 minutes.

[0092] The humidity change value △RH in step S2 includes a first threshold interval, a second threshold interval, and a third threshold interval.

[0093] Furthermore, when the humidity change value △RH is within the first threshold range, the storage method includes setting the drying time to 20 minutes and adjusting the power of the microwave board 401 according to the type of Chinese medicinal material.

[0094] When the humidity change value △RH is within the second threshold range, the storage method includes setting the drying time to 40 minutes and adjusting the power of the microwave board 401 according to the type of Chinese medicinal material.

[0095] When the humidity change value △RH is in the third threshold range, the storage method includes setting the drying time to 60 minutes and adjusting the power of the microwave board 401 according to the type of Chinese medicinal material.

[0096] The first threshold interval is when the humidity change value is less than or equal to 0 (i.e., ΔRH≤0), the second threshold interval is when the humidity change value ΔRH is greater than 0 and less than or equal to (i.e., 0<ΔRH≤15), and the third threshold interval is when the humidity change value ΔRH is greater than 15% (i.e., ΔRH>15%).

[0097] Specifically, after the user places the Chinese medicinal herbs into the storage chamber 20 and seals it, the user presses the open button on the touchscreen 60. At this time, the control center will start the vacuum pump 301 to extract the air from the storage chamber 20, creating a vacuum environment. Then, the humidity sensor 50 will detect that the humidity inside the storage chamber 20 is less than 30%. (If the humidity sensor 50 detects that the humidity inside the storage chamber 20 is greater than 30%, the vacuum pump 301 will continue to extract the air from the storage chamber 20 until the humidity sensor 50 detects that the humidity inside the storage chamber 20 is less than 30%). The humidity sensor 50 sends a stop signal to the control center. Upon receiving the signal, the control center shuts down the vacuum pump 301 and waits 30 minutes. The humidity sensor 50 then sends the humidity values ​​RH1 from 30 minutes ago and RH2 from 30 minutes later to the control center. The control center automatically calculates the humidity change value ΔRH = RH2 - RH1, allowing users to view the humidity change value ΔRH in the storage room 20 over 30 minutes on the touchscreen 60. Users can then select different drying times based on different threshold ranges of this humidity change value ΔRH. Specifically:

[0098] (1) When the humidity change value △RH≤0, select a drying time of 20 minutes on the touch screen 60.

[0099] (2) When the humidity change value △RH is 0<△RH≤15%, select a drying time of 40 minutes on the touch screen 60.

[0100] (3) When the humidity change value △RH>15%, select a drying time of 60 minutes on the touch screen 60.

[0101] Furthermore, the storage space within the control center is pre-loaded with storage methods for different Chinese medicinal herbs. The data in the storage space roughly categorizes the herbs into three types. Then, based on the category of the herb, the appropriate power of the microwave board 401 is selected. Different power levels of the microwave board 401 result in different temperatures generated during the drying, sterilization, and insect control processes of the medicinal herbs. Specifically:

[0102] Category A – Starch-based medicinal materials, such as Codonopsis pilosula, Polygonum multiflorum, rhubarb, kudzu root, Alisma plantago-aquatica, and Fritillaria cirrhosa. These medicinal materials are prone to insect infestation and moisture absorption. Therefore, the power of the microwave board 401 is 1000W-1500W, and the temperature is ≤45℃.

[0103] Category B – Sugar-containing medicinal materials, such as Polygonatum odoratum, Polygonatum sibiricum, Rehmannia glutinosa, Asparagus cochinchinensis, Codonopsis pilosula, and Scrophularia ningpoensis, which have high water and sugar content. These medicinal materials are prone to absorbing moisture and becoming sticky, moldy, and spoiled. They are also prone to melting and becoming sticky at high temperatures. Therefore, the power of the microwave board 401 is 500W-1000W and the temperature is ≤35℃.

[0104] Category C – Medicinal herbs containing volatile substances, such as Asarum, Ligusticum chuanxiong, Angelica dahurica, Rosa rugosa, Citrus medica, Aucklandia lappa, and Achyranthes bidentata. These herbs have a strong, aromatic odor and are easily discolored and change flavor due to the influence of temperature, humidity, oxygen, and light. They should not be exposed to air for extended periods, and high temperatures can accelerate the volatilization and oxidation of volatile substances. Therefore, the power of the microwave board 401 is 200W-500W, and the temperature is ≤28℃.

[0105] Therefore, after the drying time is determined, the user selects the name of the Chinese medicinal material to be placed in the storage room 20 on the touch screen 60. Then, the control center will continuously emit the corresponding power and temperature of the microwave board 401 within the selected drying time according to the name of the Chinese medicinal material. This heats and dries the Chinese medicinal material, and at the same time, it can also sterilize and kill insects.

[0106] After the microwave circuit board 401 completes its work (i.e., after the drying time ends), the control center restarts the vacuum pump 301 to extract air from the storage chamber 20 until the humidity sensor 50 detects that the humidity in the storage chamber 20 is less than 30% (of course, if the humidity sensor 50 detects that the humidity in the storage chamber 20 is less than 30% after the drying time ends, there is no need to restart the vacuum pump 301). The humidity sensor 50 will then send a stop signal to the control center, which will then shut down the vacuum pump 301. The storage chamber 20 will be opened again to retrieve medicinal herbs. If no new medicinal herbs are added to the storage chamber 20, simply maintaining a vacuum environment in the storage chamber 20 is sufficient. If new medicinal herbs are added, the above operation must be repeated to heat, dry, and sterilize the new herbs.

[0107] The refrigerator body 10 includes a refrigerator body 101 and a door 102. After the user determines the drying time and selects the corresponding Chinese medicinal material on the touch screen 60, the door 102 can be closed relative to the refrigerator body 101. Alternatively, the user can close the door 102 relative to the refrigerator body 101 while waiting for the humidity change value △RH to reach 30 minutes. After 30 minutes, the user can open the door 102, determine the drying time and select the corresponding Chinese medicinal material on the touch screen 60, and then close the door 102 again.

[0108] Example 1: When the Chinese medicinal materials placed in the storage room 20 are Class A Chinese medicinal materials, specifically rhubarb, Polygonum multiflorum, or kudzu root.

[0109] After the user places rhubarb, Polygonum multiflorum, or kudzu root into the storage chamber 20 and seals it, the user presses the open button on the touch screen 60. At this time, the control center will start the vacuum pump 301 to extract the air from the storage chamber 20, making the storage chamber 20 a vacuum environment. Then, when the humidity sensor 50 detects that the humidity in the storage chamber 20 is less than 30%, the humidity sensor 50 will send a stop electrical signal to the control center. After receiving the signal, the control center will turn off the vacuum pump 301 and wait for 30 minutes. The humidity sensor 50 will send the humidity RH1 30 minutes ago and the humidity RH2 30 minutes later to the control center. The control center will automatically calculate the humidity change value △RH = RH2 - RH1, so that the user can view the humidity change value △RH of the storage chamber 20 within 30 minutes on the touch screen 60, and then select the corresponding drying time according to the different threshold ranges of the humidity change value △RH.

[0110] After the drying time is determined, the user finds and clicks the option of rhubarb, Polygonum multiflorum, or kudzu root on the touch screen 60. The power of the microwave board 401 corresponding to rhubarb is 1000W, and the temperature is maintained at 35℃; the power of the microwave board 401 corresponding to Polygonum multiflorum is 1200W, and the temperature is maintained at 40℃; the power of the microwave board 401 corresponding to kudzu root is 1100W, and the temperature is maintained at 35℃.

[0111] Then, the control center will adjust the power and temperature of the microwave board 401 according to the selected rhubarb, Polygonum multiflorum, or kudzu root, so that the rhubarb, Polygonum multiflorum, or kudzu root will be continuously heated, dried, sterilized, and insect-killed for the selected drying time.

[0112] After the microwave circuit board 401 finishes its work, the control center restarts the vacuum pump 301 to extract air from the storage chamber 20. When the humidity sensor 50 detects that the humidity in the storage chamber 20 is less than 30%, the humidity sensor 50 will send a stop signal to the control center again. Upon receiving the signal, the control center will shut down the vacuum pump 301.

[0113] Example 2: When the Chinese medicinal materials placed in storage room 20 are Class B Chinese medicinal materials, specifically Rehmannia glutinosa, Codonopsis pilosula, or Scrophularia ningpoensis.

[0114] After placing Rehmannia glutinosa, Codonopsis pilosula, or Scrophularia ningpoensis into the storage chamber 20 and sealing it, the user presses the open button on the touchscreen 60. At this time, the control center will start the vacuum pump 301 to extract the air from the storage chamber 20, creating a vacuum environment. Then, when the humidity sensor 50 detects that the humidity in the storage chamber 20 is less than 30%, it will send a stop signal to the control center. Upon receiving the signal, the control center will turn off the vacuum pump 301 and wait for 30 minutes. The humidity sensor 50 will then send the humidity RH1 from 30 minutes ago and the humidity RH2 from 30 minutes later to the control center. The control center will automatically calculate the humidity change value △RH = RH2 - RH1, allowing the user to view the humidity change value △RH in the storage chamber 20 over 30 minutes on the touchscreen 60. The user can then select the corresponding drying time based on the different threshold ranges of the humidity change value △RH.

[0115] After the drying time is determined, the user finds and clicks the option for Rehmannia glutinosa, Codonopsis pilosula, or Scrophularia ningpoensis on the touch screen 60. The power of the microwave plate 401 corresponding to Rehmannia glutinosa is 1000W and the temperature is maintained at 35℃; the power of the microwave plate 401 corresponding to Codonopsis pilosula is 800W and the temperature is maintained at 30℃; the power of the microwave plate 401 corresponding to Scrophularia ningpoensis is 800W and the temperature is maintained at 30℃.

[0116] Then, the control center will adjust the power and temperature of the microwave board 401 according to the selected Rehmannia glutinosa, Codonopsis pilosula, or Scrophularia ningpoensis, so that the Rehmannia glutinosa, Codonopsis pilosula, or Scrophularia ningpoensis will be continuously heated, dried, sterilized, and insect-killed for the selected drying time.

[0117] After the microwave circuit board 401 finishes its work, the control center restarts the vacuum pump 301 to extract air from the storage chamber 20. When the humidity sensor 50 detects that the humidity in the storage chamber 20 is less than 30%, the humidity sensor 50 will send a stop signal to the control center again. Upon receiving the signal, the control center will shut down the vacuum pump 301.

[0118] Example 3: When the Chinese medicinal materials placed in the storage room 20 are Class C Chinese medicinal materials, specifically Asarum, Ligusticum chuanxiong, or Angelica dahurica.

[0119] After placing Asarum, Ligusticum chuanxiong, or Angelica dahurica into the storage chamber 20 and sealing it, the user presses the open button on the touchscreen 60. At this time, the control center will start the vacuum pump 301 to extract the air from the storage chamber 20, creating a vacuum environment. Then, when the humidity sensor 50 detects that the humidity in the storage chamber 20 is less than 30%, it will send a stop signal to the control center. Upon receiving the signal, the control center will turn off the vacuum pump 301 and wait for 30 minutes. The humidity sensor 50 will then send the humidity RH1 from 30 minutes ago and the humidity RH2 from 30 minutes later to the control center. The control center will automatically calculate the humidity change value △RH = RH2 - RH1, allowing the user to view the humidity change value △RH in the storage chamber 20 over 30 minutes on the touchscreen 60. The user can then select the corresponding drying time based on the different threshold ranges of the humidity change value △RH.

[0120] After the drying time is determined, the user finds and clicks the option of Asarum, Ligusticum chuanxiong, or Angelica dahurica on the touch screen 60. The power of the microwave board 401 corresponding to Asarum is 500W and the temperature is maintained at 26℃; the power of the microwave board 401 corresponding to Ligusticum chuanxiong is 400W and the temperature is maintained at 26℃; and the power of the microwave board 401 corresponding to Angelica dahurica is 500W and the temperature is maintained at 28℃.

[0121] Then, the control center will adjust the power and temperature of the microwave board 401 according to the selected Asarum, Ligusticum chuanxiong, or Angelica dahurica, so that the Asarum, Ligusticum chuanxiong, or Angelica dahurica will be continuously heated, dried, sterilized, and insect-killed for the selected drying time.

[0122] After the microwave circuit board 401 finishes its work, the control center restarts the vacuum pump 301 to extract air from the storage chamber 20. When the humidity sensor 50 detects that the humidity in the storage chamber 20 is less than 30%, the humidity sensor 50 will send a stop signal to the control center again. Upon receiving the signal, the control center will shut down the vacuum pump 301.
