Description

Technical Field

[0001] This application belongs to the technical field of disinfection cabinets, and specifically relates to an intelligent control disinfection cabinet with waste heat storage and reuse. Background Art

[0002] As a key link in public health and safety, the catering industry has extremely high requirements for tableware disinfection. According to statistics, about 30% of foodborne diseases in China are caused by tableware contamination, and high-temperature disinfection can inactivate 99.9% of pathogenic microorganisms (such as Escherichia coli and Staphylococcus aureus), which is the core means to ensure food safety. According to the "Food Safety Operation Specification for Catering Services", catering units must be equipped with disinfection equipment that meets the standards, and ensure that the surface temperature of the tableware is ≥120°C for more than 15 minutes to meet the requirements of health supervision.

[0003] Currently, high-temperature disinfection cabinets (electric heating type) are commonly used in the catering industry. Because high temperature can destroy the protein structure of microorganisms to achieve sterilization, and ultraviolet disinfection uses short-wave UV-C ultraviolet rays to destroy the DNA / RNA structure of microorganisms, making them lose their reproductive ability, so the effect of high-temperature disinfection is better. However, the thermal energy utilization efficiency of existing high-temperature disinfection cabinets is less than 50%. The power consumption for a single disinfection (150°C / 30 minutes) reaches 1.5 - 2.0 kWh, accounting for 8% - 12% of the total electricity consumption of catering stores; the proportion of cavity heat dissipation loss exceeds 40%, and the waste heat after disinfection is directly discharged into the environment without effective utilization of the waste heat.

Specific implementation mode

[0036] The intelligent control disinfection cabinet with waste heat storage and reuse of the present application will be further described in detail with reference to the attached drawings, but it is not a limitation to the present application.

[0037] As Figures 1 to 13 shown, an intelligent control disinfection cabinet with waste heat storage and reuse includes a disinfection cabinet body 1. A total heat energy utilization assembly is arranged inside the disinfection cabinet body 1. A vertically arranged partition board 2 and a heat preservation board 3 are spaced at the rear end of the cavity of the disinfection cabinet body 1. Both the partition board 2 and the heat preservation board 3 are provided with holes for air flow. The hole at the upper end of the partition board 2 is the exhaust port 201. The cavity between the partition board 2 and the heat preservation board 3 can only be connected to the inside cavity of the disinfection cabinet body 1 in a through - connection manner through the exhaust port 201 at the front end of the partition board 2.

[0038] The total heat energy utilization assembly includes an air deflector 8, a fan 9, a heat energy recovery device 6, and a heating device 7. The heating device 7 is responsible for providing the heat source for high - temperature disinfection and is arranged between the partition board 2 and the heat preservation board 3. The heat energy recovery device 6 recovers and stores heat energy after the disinfection time reaches the threshold value and is arranged between the heat preservation board 3 and the rear end plate of the cavity of the disinfection cabinet body 1. A first air distribution pipe 12 is arranged at the lower end of the heating device 7, and a second air distribution pipe 14 is arranged below the heat energy recovery device 6.

[0039] The air inlet of the fairing 8 is horizontally oriented towards the partition 2, and the fan 9 is arranged at the air inlet of the fairing 8. The exhaust end in the middle of the bottom of the fairing 8 is connected in series with the first air distribution pipe 12 and the second air distribution pipe 14 through the exhaust pipe 10, and a stop valve 13 is provided on the connecting pipeline between the first air distribution pipe 12 and the second air distribution pipe 14.

[0040] During the heating and disinfection process: The stop valve 13 is closed, and the fan 9 sucks the air inside the chamber of the disinfection cabinet body 1 into the fairing 8, and then enters the first air distribution pipe 12 through the exhaust pipe 10. Then, the air is discharged into the chamber between the partition 2 and the heat preservation board 3 through the first air distribution pipe 12, heated by the heating device 7, and then flows back into the chamber of the disinfection cabinet body 1 through the exhaust port 201 to disinfect the tableware in the chamber at a high temperature.

[0041] During the waste heat recovery process: The air inside the chamber of the disinfection cabinet body 1 is still at a high temperature. The stop valve 13 is opened, and the air flow inside the exhaust pipe 10 continues to flow into the chamber at the rear end of the heat preservation board 3. The high-temperature air heats the heat energy recovery device 6 in this chamber, and the heat energy recovery device 6 can store the heat energy. At the same time, a part of the air will also flow into the chamber between the partition 2 and the heat preservation board 3. Therefore, after the disinfection is completed, the heating device 7 is powered off, but its temperature drop takes some time and it will continue to release heat. During the waste heat recovery process, the air still flows through the heating device 7, which can further utilize the remaining heat energy of the heating device 7 and improve the utilization efficiency of the heat energy.

[0042] It is also possible to change the arrangement position of the stop valve 13. The first air distribution pipe 12 and the second air distribution pipe 14 are both connected in series with the exhaust pipe 10 through a separate pipeline with a stop valve 13. In this way, by opening the stop valves 13 at different positions, the air flow path can be changed to correspond to the heating and disinfection process and the waste heat recovery process.

[0043] In order to prevent the heated air from flowing into the chamber where the heat energy recovery device 6 is located during the heating and disinfection process, a flap 4 is provided on the hole for air flow on the upper end of the heat preservation board 3. The upper end of the flap 4 is rotatably connected to the heat preservation board 3. Under the action of gravity, the flap 4 is vertically arranged to block the hole. The flap 4 is arranged at one end of the heat preservation board 3 facing the partition 2.

[0044] The air flow is discharged from the exhaust port 201 at the upper end of the partition plate 2 and blows directly to the top of the front end of the inner chamber of the disinfection cabinet body 1, and then moves downward under the guiding action of the inner wall. In order to increase the air flow path and make it flow in a zigzag path in the inner chamber of the disinfection cabinet body 1 to optimize the high-temperature disinfection effect, the guiding cover 8 is arranged below the front end of the inner chamber of the disinfection cabinet body 1, and the air inlet of the guiding cover 8 faces the partition plate 2. One end of the partition plate 2 facing the guiding cover 8 is convexly provided with a support plate 202, and a water receiving tank 5 is arranged between the support plate 202 and the guiding cover 8.

[0045] A plurality of first through holes 203 are provided on the support plate 202. The water receiving tank 5 includes a concave tank body 501, and the front and rear ends of the tank body 501 are provided with overlapping plates 502. The two overlapping plates 502 are respectively arranged above the guiding cover 8 and the support plate 202. The end of the overlapping plate 502 located above the support plate 202 is vertically provided with a vertical plate 503 upwards. The vertical plate 503 is arranged at an interval with the partition plate 2. The first through holes 203 are arranged in the area between the vertical plate 503 at the end of the overlapping plate 502 and the partition plate 2. A drain pipe 504 communicating with the inner cavity of the tank body 501 is arranged outside the disinfection cabinet body 1, and a stop valve is arranged on the drain pipe 504 or a float switch is arranged at the through connection port of the drain pipe 504 and the tank body 501.

[0046] The heat energy recovery device 6 includes a rectangular first installation frame 601, and a plurality of single-body energy storage devices are connected inside the first installation frame 601. The single-body energy storage device is filled with a phase change energy storage material. The single-body energy storage device includes an energy storage box 603, and the energy storage box 603 is filled with a phase change energy storage material. The phase change energy storage material can adopt paraffin or inorganic salt composite material, and the melting point is 120°C to 150°C.

[0047] A screw 604 is respectively fixed on the upper, lower, left and right sides of the energy storage box 603. The screws 604 of adjacent two single-body energy storage devices are arranged correspondingly, and a threaded nut sleeve 605 is jointly sleeved on the two correspondingly arranged screws 604, and the two are fixedly connected through the nut sleeve 605. This arrangement is convenient for disassembling and replacing any single-body energy storage device.

[0048] The thickness of the first installation frame 601 is equal to the distance between the heat preservation board 3 and the rear end plate of the inner chamber of the disinfection cabinet body 1. Second through holes 602 are provided on the bottom surface and the top surface of the first installation frame 601. The second air distribution pipe 14 is arranged below the first installation frame 601, and a plurality of second air distribution branch pipes 1401 are connected through the second air distribution pipe 14. The exhaust ports of the second air distribution branch pipes 1401 are arranged corresponding to the second through holes 602.

[0049] The described heating device 7 includes a rectangular second mounting frame 701. Inside the second mounting frame 701, a number of electric heating devices 704 are connected. The heating device 704 uses quartz electric heating tubes, which are heat-resistant and have a higher thermal efficiency. The heating devices 704 are vertically arranged, and the upper and lower ends are respectively fixedly connected to the second mounting frame 701 through connecting columns 703.

[0050] To facilitate the passage of air through the second mounting frame 701, increase its contact area with the electric heating device 704, and thereby improve the heat exchange efficiency. In this embodiment, the bottom frame of the second mounting frame 701 seals the chamber between the partition plate 2 and the heat insulation plate 3 in the horizontal direction. Third through-holes 702 are provided on the bottom frame and the top frame of the second mounting frame 701. A number of first air distribution branch pipes 1201 are connected through the first air distribution pipe 12. The outlets of the first air distribution branch pipes 1201 are arranged corresponding to the third through-holes 702 at the bottom.

[0051] A number of electric heating devices 704 are connected in parallel and are individually controlled. They are electrically connected to the temperature sensor and the electric control module in the chamber of the disinfection cabinet body 1.

[0052] A cover plate 706 is covered on the third through-hole 702 of the top frame of the second mounting frame 701. Vertical guide rods 705 are fixed on both sides of each third through-hole 702 at the top of the top frame. The cover plate 706 is provided with sliding holes, and the guide rods 705 pass through the sliding holes. In the free state, the cover plate 706 abuts against the top frame under its own weight, blocking the third through-hole 702.

[0053] Based on the above embodiment, the working method of the disinfection cabinet includes the following steps:

[0054] S01. Preheating the chamber of the disinfection cabinet:

[0055] The fan 9 is turned on, the stop valve 13 connected to the first air distribution pipe 12 is closed, and the stop valve 13 connected to the second air distribution pipe 14 is opened. The air inside the exhaust pipe 10 flows into the chamber at the rear end of the heat insulation plate 3. The temperature of the air is lower than the temperature of the phase change energy storage material inside the energy storage box 603, and the air is heated. The heated air blows the flap 4 to rotate, opening the hole at the upper end of the heat insulation plate 3, and then flowing into the chamber of the disinfection cabinet body 1 through the exhaust port 201 of the partition plate 2, increasing the temperature inside the chamber.

[0056] The end time of preheating is controlled by the values detected by the temperature sensor inside the chamber and the temperature sensor at the heat energy recovery device 6. The end conditions of preheating include that the temperature inside the chamber of the disinfection cabinet body 1 reaches the threshold value, or the temperature inside the chamber of the disinfection cabinet body 1 is equal to the temperature at the heat energy recovery device 6.

[0057] S02. High-temperature disinfection of the disinfection cabinet:

[0058] The fan 9 is turned on, the stop valve 13 connected to the second air distribution pipe 14 is closed, the stop valve 13 connected to the first air distribution pipe 12 is opened, and at the same time, the electric heating device 704 is powered on to make it heat up. The air passes through the electric heating device 704, is heated by it, then pushes the cover plate 706 to move upward, and is discharged into the chamber of the disinfection cabinet body 1 through the exhaust port 201, and the tableware is disinfected by high temperature.

[0059] S03. Waste heat recovery after disinfection:

[0060] The fan 9 is turned on, the electric heating device 704 is powered off, and at the same time, the stop valves 13 connected to the first air distribution pipe 12 and the second air distribution pipe 14 are opened. In this way, the air can not only heat the phase change energy storage material inside the energy storage box 603, but also absorb the waste heat on the electric heating device 704. Then, first close the stop valve 13 connected to the first air distribution pipe 12, and then close the stop valve 13 connected to the second air distribution pipe 14 to complete the waste heat recovery.

[0061] The condition for closing the stop valve 13 connected to the first air distribution pipe 12 is: 10 to 15 minutes after the electric heating device 704 is turned off, or the temperature of the chamber where the heating device 7 is located is the same as the temperature of the chamber where the heat energy recovery device 6 is located, and further, the surface temperature of the electric heating device 704 is the same as the surface temperature of the energy storage box 603.

[0062] Since the temperature inside the disinfection cabinet body 1 is still greater than 100 °C during the high-temperature disinfection process and for some time after the disinfection is completed, if the cabinet door of the disinfection cabinet body 1 is opened at this time, the high-temperature air is likely to cause accidental burns to the human body. Therefore, in this embodiment, the door lock of the cabinet door uses an electronic lock, and the power supply circuit of the electronic lock is connected to the control circuit of the temperature sensor. Only when the temperature detected by the temperature sensor is lower than the threshold value, the power supply circuit of the electronic lock will be powered on, and the electronic lock can be opened. The threshold value can be set to 45 °C to 60 °C.

[0063] In order to realize opening the door in an emergency, an air inlet pipe communicating with its chamber is provided above the top of the disinfection cabinet body 1, and the air inlet pipe is provided with an electronically controlled stop valve. A three-way valve 11 is provided on the exhaust pipe 10, and one outlet of the three-way valve 11 is connected to the air release pipe 15 in a through manner, and the end of the air release pipe 15 penetrates to the top of the disinfection cabinet body 1.

[0064] An emergency door opening button is provided on the control panel of the disinfection cabinet body 1. Press the button, the electronically controlled stop valve of the air inlet pipe and the fan 9 are turned on, and the electronically controlled three-way valve 11 connects the exhaust pipe 10 and the air release pipe 15 in a through manner. In this way, the air inlet pipe intakes air, and the air release pipe 15 exhausts air, quickly replacing the high-temperature air inside the chamber of the disinfection cabinet body 1 with normal-temperature air to prevent burns.

[0065] The embodiments of the present application have been described in detail above in conjunction with the accompanying drawings. However, the present application is not limited to the above embodiments, and various changes can be made without departing from the gist of the present application within the scope of knowledge possessed by those of ordinary skill in the art.
