DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] In order to solve the problems that it is impossible to identify and adjust whether the food is laid evenly, the debris dropped during food production will affect the production environment of the workshop, and the ventilation and cooling of densely packed food will be hindered, embodiment 1 is proposed: like Figures 1 to 8 As shown, the present invention discloses a food workshop processing cooling device, including a box assembly 1, a feed port 2 is arranged on the top of the box assembly 1, a discharge port 3 is arranged on one side of the bottom of the box assembly 1, a circulation chamber 7 is arranged on the other side of the bottom of the box assembly 1, an air cooling assembly 4 and a filtering assembly 5 are arranged in the circulation chamber 7, and a plurality of transmission assemblies 6 are arranged inside the box assembly 1.

[0024] By setting the filter component 5 at the suction end of the air cooling component 4, the residue and debris dropped on the food are filtered and collected to prevent the residue and debris from entering the air cooling component 4 with the wind. By sealing the air cooling component 4 and the box component 1, the continuous circulation of the air flow inside the box component 1 is achieved. By setting the transmission component 6, the uniformity of food spreading, temperature, and humidity are detected in real time, and targeted adjustments are made.

[0025] When the user puts food materials from the feed port 2 onto the transmission component 6, due to the different types of food materials, different friction forces and different rolling degrees, the material distribution is uneven, and the food will accumulate in a cone shape and concentrate on the middle line of the transmission component 6, which is not convenient for comprehensive heat dissipation of the food. The cold air cannot pass evenly between the materials, resulting in the cooling effect of the food being affected.

[0026] like Figure 3-Figure 4 As shown, the transmission component 6 includes an inner plate 608, a scraper 614 is slidably provided on the outside of the inner plate 608, a sliding cavity is opened inside the inner plate 608, an electromagnet 610 is fixedly provided at the bottom end of the sliding cavity, and a buffer spring 611 is provided on the outside of the electromagnet 610.

[0027] The transmission assembly 6 also includes a swing motor 607, which is rotatably arranged on the connection plate 605, and a fixed block 606 is fixedly arranged on the outer surface of the swing motor 607, and a rotating motor 609 is fixedly arranged on the top of the fixed block 606, and the output end of the rotating motor 609 is fixedly connected to the inner plate 608; the scraper 614 is provided with a humidity sensor and a temperature sensor, one end of the buffer spring 611 is fixedly arranged at the bottom end of the sliding cavity, and the other end is fixedly connected with a sliding rod 613, and a permanent magnet 612 is fixedly arranged on the end of the sliding rod 613 facing the electromagnet 610; when the electromagnet 610 is not powered, the buffer spring 611 is in a relaxed state, and a repulsive force or an attractive force is generated on the permanent magnet 612 by controlling the electromagnet 610 to pass currents in different directions, and the buffer spring 611 is in a stretched or compressed state. The electromagnet 610 passes currents in different directions, which can generate an attractive force or a repulsive force on the permanent magnet 612. The transmission assembly 6 also includes a support plate 601 arranged in parallel, a transmission wheel 615 is arranged on the opposite side of the support plate 601, a transmission shaft 616 is fixedly arranged at the center of the transmission wheel 615, and a transmission motor 617 is fixedly arranged at one end of the transmission shaft 616; arc grooves are evenly arranged on the circumference of the transmission wheel 615, and circular nodes are evenly arranged on the transmission bar 602, and the outer edge of the circular node is embedded in the arc groove. When the transmission motor 617 drives the transmission wheel 615 to rotate through the transmission shaft 616, the transmission wheel 615 drives the transmission bar 602 to rotate through the arc groove to complete the loading and unloading of food. Transmission bars 602 are arranged around the circumference of the transmission wheel 615, and support rods 603 are evenly arranged between the transmission bars 602. The support rods 603 are arranged corresponding to the circular nodes. Fixed rings 604 are evenly arranged on the support rods 603, and connecting plates 605 are symmetrically arranged on both sides of the fixed ring 604. The swing motor 607 is rotatably arranged on the connecting plate 605.

[0028] During use, the user puts food materials into the outer box 101 through the feed port 2. When the food materials fall onto the scraper 614, the scraper 614 is subjected to the pressure brought by the weight of the food materials, driving the sliding rod 613 to move toward the inside of the sliding cavity, thereby compressing the buffer spring 611. Taking the compression of the buffer spring 611 as a signal, the conveying motor 617 is started to drive the conveying bar 602 to convey, thereby driving the scraper 614 to move and conveying the food materials falling on the scraper 614. When the food materials fall onto the scraper 614 of the next-level transmission component 6, the conveying motor 617 of the next level is started until there are compressed buffer springs 611 on the top layers of all the transmission components 6 in the longitudinal direction, indicating that the food materials have vertically covered the scraper 614 on the top layer of the transmission component 6 at this time, and the rotation of the conveying motor 617 is stopped. At this time, although the food materials have vertically spread over the top layer of the transmission component 6, the rolling degree of different types of food materials is inconsistent, resulting in uneven lateral distribution of the food materials. It is necessary to detect the distribution of the food materials on the scraper 614, so as to control the scraper 614 to adjust the distribution of the food materials.

[0029] like Figure 3 As shown, the scraper 614 is initially parallel to the horizontal direction and supports the food material. The weight of the material itself will compress the buffer spring 611. By detecting the distribution of the buffer spring 611 that generates compression on the transmission component 6, the current distribution of the food material can be obtained. When it is detected that the buffer spring 611 located in the middle position of the horizontal direction generates compression, the buffer springs 611 on both sides have no compression or the compression is less than the buffer spring 611 in the middle position, it can be known that the current food material is concentrated in the middle position of the horizontal direction. At this time, Figure 4 As shown, the rotating motor 609 in the range of uneven distribution of food materials is controlled to rotate 90° in the interval row, thereby driving the scraper 614 in the interval row to rotate 90°. The scraper 614 in the interval row is parallel to the longitudinal direction, and the scraper 614 that has not rotated 90° serves as a support for the food materials.

[0030] Furthermore, for the scraper 614 that rotates 90°, with a row of scraper 614 located in the middle of the horizontal direction as the middle line, the scraper 614 on both sides is controlled to rotate toward the middle line to be in an inclined state, that is, the swing motor 607 is started to rotate, and the inner plate 608 and the scraper 614 are driven to rotate through the fixed block 606, so that the scraper 614 on both sides of the middle line is tilted toward the middle line. At the same time, the electromagnet 610 under the tilted scraper 614 is controlled to pass a positive current to generate a repulsive force on the permanent magnet 612, so that the buffer spring 611 is stretched, and the slide The movable rod 613 drives the scraper 614 to move in the direction away from the electromagnet 610, thereby increasing and temporarily fixing the length of the scraper 614, and then controlling the swing motor 607 to rotate in the direction away from the center line, thereby lifting and moving the food material at the bottom layer. After completing one movement, the electromagnet 610 is controlled to pass a reverse current to generate an attraction to the permanent magnet 612, so that the buffer spring 611 is compressed, thereby shortening and temporarily fixing the length of the scraper 614, and then controlling the swing motor 607 to rotate in the direction of the center line, and repeating the above actions to move the material next time.

[0031] It should be noted that if the material is accumulated on either side in the horizontal direction, a row of scrapers 614 located on the side of the accumulation position away from the material that needs to be evenly distributed is used as a reference line, and the remaining scrapers 614 are controlled to rotate toward the reference line to an inclined state. Subsequently, the material on the accumulation side is moved to the other side in the same way to solve the problem of uneven material distribution. In this embodiment, food material is accumulated on the horizontal middle line as an example for explanation.

[0032] As the bottom layer of food material moves, the bottom layer of material is moved to the lateral sides, and the top layer of food material begins to collapse and fall to the lateral middle position, thereby completing the adjustment of the lateral uniform distribution of the material. When the compression amounts of all buffer springs 611 at the top of the transmission component 6 are basically similar, it can be determined that the current material has been evenly distributed on the transmission component 6, and the air cooling component 4 is subsequently turned on for cooling.

[0033] By detecting the compression amount of the buffer spring 611, it is judged whether the food material is fully distributed longitudinally, thereby controlling whether the material is transmitted. Then, by detecting the uniformity of the compression amount of the buffer spring 611, it is judged whether the food material is uniformly distributed laterally. The distribution of the food material is adjusted by controlling the scraper 614.

[0034] During the process of the scraper 614 adjusting the distribution of the food material, debris is generated due to the mutual friction between the materials. The debris falls to the bottom of the outer box 101 and accumulates. A common debris collection method is to set the bottom of the outer box 101 to be open and set a component for receiving the debris underneath. However, this method easily causes the debris to fly around and affects the environment of the processing workshop.

[0035] Further, in order to solve the above technical problems, Figure 5-Figure 6 As shown, an air outlet 103 is arranged at the bottom of the outer box 101, and a filter plate 501 and an air cooling component 4 are arranged at the end of the air outlet 103 in sequence. The air cooling component 4 generates a suction force to extract the air inside the outer box 101. The impurities and debris in the air are filtered by the filter plate 501 and then enter the air cooling component 4 for refrigeration. The air cooling component 4 refrigerates the air and then inputs it into the outer box 101 to form a closed air circulation to prevent debris from flying around. The air cooling component 4 includes a refrigeration group 401 fixedly arranged in the circulation chamber 7, the suction end of the refrigeration group 401 is arranged toward the filter component 5, an air supply pipe 402 is fixedly arranged at the top of the circulation chamber 7, the output end of the refrigeration group 401 is arranged toward the air supply pipe 402, a hose 403 is fixedly arranged on the top of the air supply pipe 402, and an air supply platform 404 is fixedly arranged at one end of the hose 403 away from the air supply pipe 402. The filter component 5 includes a filter plate 501. The air flow direction is as follows: the air inside the outer box 101 passes through the square through hole 102, the air outlet 103, and the filter plate 501 in sequence, enters the internal refrigeration of the refrigeration group 401, and then passes through the air supply pipe 402, the hose 403, and the air supply platform 404 in sequence before being input into the outer box 101. The box assembly 1 includes the outer box 101, and the bottom of the outer box 101 is provided with a square through hole 102, the outside of the square through hole 102 is fixedly provided with an air outlet 103, and the air outlet 103 is fixedly connected to the circulation chamber 7. Maintenance doors 104 are evenly arranged on the sides of the outer box 101, and baffles 105 are arranged on both sides of the inner side of the outer box 101. The baffles 105 are used to prevent food materials from falling from the transmission assembly 6.

[0036] During use, when the compression amounts of all buffer springs 611 located at the top of the transmission component 6 are basically similar, it means that the material has been evenly distributed on the transmission component 6. At this time, the refrigeration group 401 is turned on to extract the air inside the outer box 101. The air is extracted from the air outlet 103, filtered by the filter plate 501 for impurities and debris, and then enters the interior from the suction end of the refrigeration group 401. After being cooled, the air is output from the output end of the refrigeration group 401. The refrigerated air passes through the air supply pipe 402 and the hose 403 in turn, and is finally input into the outer box 101 again from the air supply platform 404. The cooled air contacts the food material on the transmission component 6 in turn. After cooling the material, it is extracted again by the refrigeration group 401, forming an air circulation inside the outer box 101 to prevent debris from flying around and ensure air quality.

[0037] By setting up a filter plate 501, debris and impurities in the air are collected and filtered, and at the same time, impurities can be prevented from entering the interior of the refrigeration group 401, resulting in debris accumulation inside the refrigeration group 401, affecting the subsequent suction effect. By setting the refrigeration group 401 and the outer box body 101 in a closed connection, while assisting in collecting debris, an internal air circulation is formed to avoid the leakage and flying of material debris, thereby ensuring the air quality of the workshop.

[0038] When the temperature sensor detects that the food temperature has dropped to the qualified temperature, the conveying motor 617 is started to drive the conveying bar 602 to convey the food material to the discharge port 3 until it is detected that the compression of all buffer springs 611 disappears and returns to the initial state. At this time, the next round of food material is added.

[0039] Since different food materials require different raw materials, the density and porosity of the materials produced by different raw materials are also different. When the density of the material is small, the porosity is large, and the cold air can easily pass through the pores. When the density of the material is large, the porosity is small, and the materials pile up to form a windbreak wall, which makes it difficult for the cold air to pass through the pores of the material, and it is unable to fully contact the material and quickly cool it down.

[0040] In order to solve the above technical problems, a temperature sensor is set on the scraper 614 to detect the temperature of the current material in real time. When the scraper 614 has adjusted the uniform distribution of the food material and the air cooling component 4 starts ventilation, the readings of the temperature sensors on the scrapers 614 at different levels will change. If the temperatures detected by the temperature sensors on the scrapers 614 at different levels are basically synchronized and decrease evenly, it means that the material on each level is in full contact with the cold air and the material temperature is gradually decreasing. If the temperature difference displayed by the temperature sensor on the transmission assembly 6 between different levels is large, and the compression amount of the buffer spring 611 in the transmission assembly 6 located at the top layer increases as a whole, it means that the current material has a large density and a small ventilation volume, which makes it difficult for the cold wind to pass through. The cold wind is blocked at the top by the material on the top layer, and the wind force exerts pressure on the buffer spring 611 on the top layer. At the same time, the material on the lower layer cannot effectively contact the cold wind, resulting in inconsistent compression amounts of the buffer spring 611 between different levels and inconsistent material temperature drop speeds. At this time, with a row of scrapers 614 located in the middle of the horizontal direction as the middle line, the electromagnets 610 under the scrapers 614 of the interval rows on both sides of the middle line are energized to generate a repulsive force on the permanent magnet 612, so that the buffer spring 611 is stretched, and the scraper 614 moves to the farthest distance in the direction away from the electromagnet 610, increasing the length of the scraper 614. At this time, the scrapers 614 of adjacent rows have a height difference with each other, which lifts up part of the material, so that a height difference is generated between the materials, and a gap appears, which facilitates the passage of cold wind, ensures the contact degree between the material and the cold wind, and ensures the cooling efficiency.

[0041] Through the combination of the temperature sensor and the buffer spring 611, the contact degree between the current food material and the cold air is judged, and the contact degree between the material and the cold air is guaranteed by controlling the scraper 614 and the electromagnet 610 to avoid the excessive density of the material causing the cold air to be unable to pass through the material, resulting in inconsistent material cooling and affecting the cooling efficiency.

[0042] The working principle of the present invention is as follows: first, food materials are loaded, and the user puts the food materials into the outer box body 101 through the feed port 2. The food materials fall onto the scraper 614 of the top layer of the transmission component 6. The scraper 614 is subjected to the pressure brought by the weight of the food materials, driving the sliding rod 613 to move toward the inside of the sliding cavity, thereby compressing the buffer spring 611. Taking the compression of the buffer spring 611 as a signal, the transmission motor 617 is started to drive the transmission bar 602 to transmit, thereby driving the scraper 614 to move and transmitting the food materials falling on the scraper 614. When the food materials fall onto the scraper 614 of the next-level transmission component 6, the buffer spring 611 of the next level is compressed, and the transmission motor 617 is started until there are compressed buffer springs 611 in the longitudinal direction of the top layers of all the transmission components 6, which means that the food materials have longitudinally covered the scraper 614 of the top layer of the transmission component 6, and the rotation of the transmission motor 617 is stopped.

[0043] Secondly, the weight of the food material itself will compress the buffer spring 611 when the food material is evenly distributed. By detecting the distribution of the buffer spring 611 that has generated compression on the transmission component 6, the current distribution of the food material can be obtained. Since the rolling degree of different materials is inconsistent, the distribution is variable. In this embodiment, the food material is piled up on the horizontal middle line as an example for explanation; when it is detected that the buffer spring 611 located in the horizontal middle position generates compression, the buffer springs 611 on both sides have no compression or the compression is less than the buffer spring 611 in the middle position, it can be known that the current food material is concentrated in the horizontal middle position. At this time, Figure 4 As shown, the rotating motor 609 in the range of uneven distribution of food materials is controlled to rotate 90° in the interval row, thereby driving the scraper 614 in the interval row to rotate 90°. The scraper 614 in the interval row is parallel to the longitudinal direction, and the scraper 614 that has not rotated 90° serves as a support for the food materials.

[0044] For the scraper 614 that rotates 90 degrees, take the scraper 614 in the middle of the horizontal row as the center line, start the swing motor 607 to start rotating, and drive the inner plate 608 and the scraper 614 to rotate through the fixed block 606, so that the scrapers 614 in the interval rows on both sides of the center line rotate toward the center line to be in an inclined state. At the same time, control the electromagnet 610 under the inclined scraper 614 to pass a positive current, generate a repulsive force on the permanent magnet 612, so that the buffer spring 611 is stretched, and the sliding rod 613 drives the scraper 614 to move away from the electromagnet 610, thereby increasing and temporarily fixing the length of the scraper 614, and then control the swing motor 607 to rotate away from the center line, so that the food at the bottom layer is moved. The material is lifted and moved. After completing one movement, the electromagnet 610 is controlled to pass a reverse current to generate an attraction to the permanent magnet 612, so that the buffer spring 611 is compressed, thereby shortening and temporarily fixing the length of the scraper 614, and then controlling the swing motor 607 to rotate toward the center line to the initial tilted state, and then controlling the electromagnet 610 to pass a forward current to increase and temporarily fix the length of the scraper 614, and then repeating the above actions to move the material next time, so that the scraper 614 keeps swinging back and forth to level the material. After leveling, the material at the bottom layer is moved to the lateral sides, and the food material at the top layer begins to collapse and fall to the lateral middle position, thereby completing the adjustment of the uniform lateral distribution of the material.

[0045] Then, air cooling is performed. When the compression amounts of all the buffer springs 611 located at the top of the transmission component 6 are basically similar, it can be determined that the current material has been evenly distributed on the transmission component 6. At this time, the refrigeration group 401 is turned on to extract the air inside the outer box 101. The air is extracted from the air outlet 103, filtered by the filter plate 501 for impurities and debris, and then enters the interior from the suction end of the refrigeration group 401. After cooling, it is output from the output end of the refrigeration group 401. The cooled air passes through the air supply pipe 402 and the hose 403 in turn, and is finally input into the outer box 101 again from the air supply platform 404. The cooled air contacts the food material on the transmission component 6 in turn. After cooling the material, it is extracted again by the refrigeration group 401, forming an air internal circulation inside the outer box 101 to prevent debris from flying around and ensure air quality.

[0046] Finally, when the temperature sensor detects that the food temperature has dropped to the qualified temperature, the conveying motor 617 is started to drive the conveying bar 602 to convey the food material to the discharge port 3 until it is detected that the compression of all buffer springs 611 disappears and returns to the initial state, indicating that all food materials on the current transmission component 6 have been unloaded. At this time, the next round of food materials can be put in.

[0047] Embodiment 2: Based on the technical solution of the above-mentioned embodiment 1, during the process of cooling the food, when the cold air is initially introduced, the temperature of the food is relatively high. When it encounters the cold air, water droplets will be produced. If not handled, the moisture content of the food will be high, affecting the subsequent processes. When the filter plate 501 filters the debris, as the cooling continues, the cold air drawn out from the outer box 101 has a certain humidity, causing the debris subsequently drawn out to adhere to the filter plate 501 and cannot fall into the collection box 506 for collection. The following technical solution is proposed to solve the above-mentioned technical problems.

[0048] When the humidity sensor detects that the humidity of the current food material increases, it means that water droplets are condensed on the surface of the food material. At this time, the refrigeration group 401 is controlled to intermittently increase the output wind force of the cold wind, and the suction force of the suction end also changes with the output wind force. The sudden increase in wind force will increase the pressure on the food material and the scraper 614, and the height will decrease, thereby increasing the compression of the buffer spring 611. The wind force is restored, and the buffer spring 611 is reset, driving the food material and the scraper 614 to rise back to the initial height, thereby forming a reciprocating lifting process, and the water droplets on the surface of the food material are thrown out. The thrown water droplets are pulled out of the outer box 101 with the wind force, and are intercepted by the filter plate 501 together with the debris.

[0049] As the food material is in continuous contact with the cold air, the temperature will slowly decrease, and the temperature difference with the cold air will gradually decrease until no more condensation and water droplets are produced. When the humidity sensor reading gradually decreases to the original value, it means that there are no water droplets on the surface of the food material at this time, and the intermittent wind output of the refrigeration group 401 is stopped, and the buffer spring 611 returns to stability after being reset.

[0050] The humidity of the food material is detected in real time by the humidity sensor, and the output strength of the wind force is controlled and adjusted to assist the buffer spring 611 in throwing away the water droplets on the material.

[0051] Furthermore, if Figures 7 and 8 As shown, the filter plate 501 is cleaned by setting a reset spring 504 and a cleaning frame 502. The filter plate 501 is evenly fixed with an inclined rod 503, and the outer side of the inclined rod 503 is sleeved with a reset spring 504. The cleaning frame 502 is slidably set on the inclined rod 503. The cleaning frame 502 is provided with an inclined hole, and the inclined rod 503 passes through the inclined hole and can slide along the inclined hole. The cleaning frame 502 is evenly fixed with bristles 505. The cleaning frame 502 is slidably set on the inner wall of the circulation chamber 7, and vertically rises and falls along the inner wall of the circulation chamber 7. The bottom of the circulation chamber 7 is provided with a long through hole 507, and a collection box 506 is slidably set on the long through hole 507. The filter plate 501 is slidably set on the inner wall of the circulation chamber 7, and moves horizontally along the inner wall of the circulation chamber 7.

[0052] During use, as more and more debris adheres to the filter plate 501, the ventilation volume of the filter plate 501 will become smaller and smaller. At this time, the wind force will be hindered when passing through, thereby pushing the filter plate 501 to move along the side wall of the circulation chamber 7 close to the cleaning frame 502. During the movement of the filter plate 501, the inclined rod 503 slides in the inclined hole on the cleaning frame 502, thereby driving the cleaning frame 502 to vertically descend along the inner wall of the circulation chamber 7. At the same time, when the filter plate 501 is close to the cleaning frame 502, the bristles 505 on the cleaning frame 502 touch the filter plate 501. As the wind force continues to push, the cleaning frame 502 continues to descend, driving the bristles 505 to clean the filter plate 501, and sweeping the debris adhered to the filter plate 501 into the collection box 506, completing the cleaning of the filter plate 501 and ensuring the ventilation volume.

[0053] By utilizing the interaction between wind force and the filter plate 501 with too much debris adhesion resulting in a small ventilation volume, the cleaning frame 502 cleans the filter plate 501 to ensure the ventilation volume of the filter plate 501.

[0054] When the scraper 614 evenly distributes the food material, by controlling part of the scraper 614 to swing back and forth to support the movement of the material, friction will be generated between the food materials, causing debris on the material to fall off. Some materials themselves have a certain amount of humidity, causing the debris to stick to the scraper 614, thereby affecting the detection accuracy of the temperature sensor and the humidity sensor.

[0055] Furthermore, in order to solve the above technical problems, the user can observe the surface of the scraper 614 through the maintenance door 104. When debris is observed to be attached to the surface of the scraper 614, after completing one unloading, the loading is stopped and the cleaning mode is turned on. In the cleaning mode, all the rotating motors 609 are controlled to drive the scraper 614 to rotate 90°, and the scraper 614 is parallel to the longitudinal direction. The electromagnets 610 in the interval columns are controlled to pass reverse current to generate attraction for the permanent magnets 612. The sliding rod 613 drives the scraper 614 to move to the limit in the direction of the electromagnet 610, and the scraper 614 is temporarily fixed. When the scraper 614 slides along the inner plate 608, the scraper 614 is rotated 90°. In the process, the debris adhering to the surface of the inner plate 608 can also be scraped off, and then the remaining swing motor 607 is controlled to drive the scraper 614 to rotate. Since the remaining buffer spring 611 is in a relaxed state, as the swing motor 607 rotates, the tip of the scraper 614 contacts the temporarily fixed scraper 614 and slides along its surface to scrape off the debris adhering to its surface. After the scraping is completed, the swing motor 607 is controlled to rotate and reset, and then the rotating motor 609 is controlled to drive the fixed scraper 614 to rotate 180° uniformly, and then the remaining swing motor 607 is controlled to drive the scraper 614 to complete the debris cleaning of the surface. Then clean the remaining scraper 614 according to the above steps to prevent the debris from adhering to the scraper 614 and affecting the detection accuracy of the temperature sensor and the humidity sensor.

[0056] By observing the adhesion of debris on the surface of the scraper 614, the electromagnet 610, the scraper 614 and the buffer spring 611 are controlled to cooperate with each other to clean the debris on the surface of the scraper 614, thereby ensuring the detection accuracy of the temperature sensor and the humidity sensor.
