Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology, specifically to a modular heat exchange equipment. Background Technology

[0002] Everyday life generates food scraps, which are usually discarded with household waste. However, for those who grow flowers and vegetables, these discarded vegetable leaves, leftover food, fruit peels, eggshells, tea dregs, bones, etc., are excellent sources of organic fertilizer. Traditionally, household food scrap composting mainly uses compost bins and compost machines. However, compost bins are slow and produce noticeable odors, making them unsuitable for use in residential buildings. Therefore, residential households primarily purchase compost machines for composting or drying food scraps or food.

[0003] Rice cookers are essential food preparation appliances in households. Compared to rice cookers, which have a huge market, mature technology, optimized supply chain, and low cost, composters also have heating elements. Furthermore, the temperature control functions of rice cookers, such as keep-warm function, are compatible with those of composters, or can be easily adjusted. The cost of the mixing, filtering, and deodorizing mechanisms required for composting is relatively low. However, due to the small market and production scale, the unit price of composters remains high. Therefore, consumers who need composting equipment not only have to spend a high price to buy two devices, both of which occupy kitchen counter space, but they also have to abandon the purchase of a composter and instead discard food scraps and buy fertilizer.

[0004] Therefore, the research objective of this invention is to design a modular heat exchange device that utilizes a mature electric rice cooker heating shell, and allows for the replacement of different inner pots and lids with different heating modes to cook or dry food. This device aims to reduce equipment costs while achieving dual food processing functions. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a modular heat exchange device that can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is:

[0007] A modular heat exchange device, comprising:

[0008] The housing has a heat exchange chamber and a corresponding main heat source. An electronic control module for adjusting and controlling different operating modes of the main heat source is installed on the housing.

[0009] The first heat exchange container and the second heat exchange container are detachably and alternately disposed in the heat exchange chamber. A corresponding stirrer is rotatably installed in the second heat exchange container. When the first heat exchange container or the second heat exchange container is installed in place, the main heat source contacts it and provides a heat source of the corresponding mode.

[0010] The first and second sealing caps are respectively adapted to and used to seal the first or second heat exchange container. When the first or second heat exchange container is installed in place, the first or second sealing cap is connected to the shell. Both the first and second sealing caps are provided with air vents that connect the inside and outside.

[0011] The drive mechanism is electrically connected to the electronic control module and is used to drive the agitator inside the second heat exchange container, which is installed in place, to rotate.

[0012] A locking mechanism is used to circumferentially limit and lock the second heat exchange container and the second sealing cover when they are connected and move toward the housing to a distance less than a set threshold L.

[0013] The locking mechanism includes a self-locking component installed on the second sealing cover for circumferentially limiting and fixing the second heat exchange container, and a distance-limiting electrical connection component for controlling the automatic opening and closing of the self-locking component; when the distance between the second sealing cover and the housing is less than a set threshold L, the distance-limiting electrical connection component controls the self-locking component to be energized to circumferentially lock the second sealing cover and the second heat exchange container; when the distance between the second sealing cover and the housing is greater than the set threshold L, the self-locking component is de-energized and unlocked.

[0014] The distance-limiting electrical connection component consists of a distance measuring module and a relay. The distance measuring module is a Bluetooth proximity switch with integrated distance measuring function installed on the second closed cover, or it consists of a controller and two Bluetooth distance measuring modules or UWB modules respectively installed on the second closed cover and the housing. The Bluetooth proximity switch or controller controls the relay according to the distance data, and the relay controls the power supply of the self-locking component.

[0015] The second sealing cover is recessed inward and has a guide groove. The periphery of the second heat exchange container is integrally formed with a limiting block. After the second heat exchange container is connected to the second sealing cover, the limiting block moves to the side of the guide groove. The self-locking component is a push-pull solenoid valve installed on the second sealing cover. The push-pull solenoid valve includes a coil electrically connected to a power source through the limiting electrical connection component, and an iron core movable within the coil through a corresponding elastic element. The side of the guide groove is provided with a corresponding through hole. When the coil is energized, the coil generates magnetic force to form a linear thrust that pushes the iron core outward and inserts it into the through hole. The elastic element is compressed, and the limiting block is then limited and fixed between the iron core and the guide groove.

[0016] The second sealing cover is also provided with a display component for determining whether the self-locking component is locked or not. The display component is an indicator light connected to the power supply via a trigger switch. The trigger switch is installed on the coil. When the coil is powered by electromagnetic attraction, it drives the iron core to move into place and the iron core touches the trigger switch. The indicator light is lit up, otherwise the indicator light is dark.

[0017] The second sealing cover and the corresponding side of the housing are provided with corresponding metal magnetic contacts. The power source is a rechargeable battery and is electrically connected to the metal magnetic contacts on the second sealing cover. When the second sealing cover is connected to the housing, the rechargeable battery is charged.

[0018] The drive mechanism is installed inside the second closed cover or housing. The drive mechanism includes a drive motor and a connector fixedly installed on the output shaft end of the drive motor. A corresponding bearing seat is fixedly installed on the inner bottom of the second heat exchange container. A corresponding connecting seat is rotatably installed through the bearing seat. The stirrer is integrally formed and fixedly connected to the connecting seat. When the drive mechanism is installed inside the housing, the bearing seat is a bidirectional bearing seat. After the second heat exchange container and the second closed cover are installed in sequence, the shaft on the bidirectional bearing seat is fixedly connected to the connector. When the drive mechanism is installed inside the second closed cover, an upwardly extending connecting shaft is fixedly installed on the top of the connecting seat. After the second heat exchange container and the second closed cover are installed in sequence, the connecting shaft is fixedly connected to the connector.

[0019] When the drive mechanism is installed inside the housing, an isolation cover for isolating the heat source is fixedly installed on the housing inside the heat exchange cavity. The main heat source is installed inside the isolation cover, and the drive motor and the electronic control module are installed in the receiving cavity formed by the isolation cover and the housing.

[0020] The first sealing cover has a detachable sealing plate on the side facing the first heat exchange container, and a sealing ring is detachably fitted around the periphery of the sealing plate. The sealing plate has a plurality of air guide holes that communicate with the air outlet. After the first heat exchange container and the first sealing cover are installed in place, the sealing ring is pressed together to form a seal on the first heat exchange container.

[0021] The second sealing cover has a detachable sealing ring on the side facing the second heat exchange container. After the second heat exchange container and the second sealing cover are connected, the sealing ring is pressed between the second sealing cover and the second heat exchange container, forming a seal for the second heat exchange container. The side of the second sealing cover facing the second heat exchange container has a corresponding air guide hole, and the air guide hole is connected to the air outlet through a corresponding exhaust channel and a filter mechanism. The side of the second sealing cover facing the second heat exchange container also has a corresponding temperature and humidity detection module. The filter mechanism includes an exhaust fan and an adsorption filter element arranged sequentially in the exhaust channel. The gas in the second heat exchange container is discharged after the adsorption filter element adsorbs odors. The drive mechanism, exhaust fan, and temperature and humidity detection module are electrically connected to the electronic control module through metal magnetic contacts.

[0022] Advantages of this invention:

[0023] 1) This invention utilizes the mature technology of a rice cooker heating shell, combined with different heating modes, and allows for the replacement of different inner pots and lids according to different processing requirements, to achieve cooking or drying of food. This reduces equipment costs while realizing dual food processing functions. Furthermore, a locking mechanism is added to the second heat exchange container and the second sealing lid for circumferential locking control. When the distance between the container and the shell is less than a set threshold L, the locking mechanism is activated to circumferentially limit and lock the connection between the second heat exchange container and the second sealing lid. This ensures that the consumer can only open the second heat exchange container and the second sealing lid after maintaining a distance of less than the set threshold L from the shell, thus exposing the dried or composted food. This prevents the material or odor generated by drying or composting from contaminating the shell or the environment in which the shell is located, maintaining the cleanliness of the environment in which the shell is located. As a result, the heating food processor can simultaneously have dual modes of food drying and cooking.

[0024] 2) The locking mechanism of the present invention consists of a self-locking component for circumferentially limiting and fixing the second heat exchange container, and a distance-limiting electrical connection component for controlling the automatic opening and closing of the self-locking component. The Bluetooth proximity switch, or Bluetooth ranging module or UWB module with integrated ranging function in the distance-limiting electrical connection component senses the distance between the second sealing cover and the housing. The Bluetooth proximity switch or controller controls the relay according to the distance data, and then controls the power supply of the self-locking component. After the power supply is connected to the coil, the iron core is inserted into the through hole of the second sealing cover under the linear thrust formed by the magnetic force generated by the coil, thereby circumferentially fixing the second sealing cover and the second heat exchange container. Within the usage range of the set threshold L, the second sealing cover and the second heat exchange container cannot be opened manually. They can only be opened manually after the automatic power is cut off and unlocked outside the limited distance, ensuring the limitation of use and practical effect.

[0025] 3) This invention further incorporates a display component on top of the self-locking component. A trigger switch electrically connected to the indicator light is installed on the coil. When the self-locking component is activated, the iron core moves into position and touches the trigger switch to connect the power supply and the trigger switch. This visually reminds the consumer that the second sealing cover and the second heat exchange container are circumferentially locked. In other words, the display component allows for a direct determination of whether the locking mechanism is activated, further preventing accidental opening of the second sealing cover within the usage space and ensuring cleanliness during use. Furthermore, the display component can only be activated when the self-locking component is in position. If the second sealing cover and / or the second heat exchange container are not connected and are close to the housing, the display component will not be triggered, thereby saving energy and ensuring practicality.

[0026] 4) The present invention installs the drive mechanism for driving the stirrer in the second heat exchange container inside the shell, and uses the isolation cover to isolate the main heat source and the drive mechanism, thereby effectively protecting the drive mechanism; or the drive motor is installed in the second closed cover to isolate the drive mechanism and the main heat source, so as to avoid the main heat source from affecting the drive mechanism, and further ensure the practical effect of the present invention.

[0027] 5) This invention adapts different first and second sealing covers to the first and second heat exchange containers. Both the first and second sealing covers are provided with corresponding sealing rings to ensure the internal sealing when the first and second sealing covers are connected to the corresponding inner liner. Furthermore, the second sealing cover is equipped with components such as a filtration mechanism and a temperature and humidity detection module required for drying or composting, thereby providing the corresponding equipment requirements for drying and composting. In addition, corresponding metal magnetic contacts are provided on the side of the second sealing cover opposite to the shell. When the second and first sealing covers are connected to the shell, the drive mechanism, filtration mechanism and temperature and humidity detection module are electrically connected through the metal magnetic contacts to ensure practicality.

Detailed Implementation

[0041] To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings:

[0042] Example 1

[0043] refer to Figure 1-8 A modular heat exchange device, comprising:

[0044] The housing 1 has a heat exchange chamber 101 and a corresponding main heat source 10 inside the heat exchange chamber 101. An electronic control module 18 for adjusting and controlling different operating modes of the main heat source 10 is installed on the housing 1.

[0045] The first heat exchange container 2 and the second heat exchange container 3 are detachably and alternately disposed in the heat exchange chamber 101. A corresponding stirrer 4 is rotatably installed in the second heat exchange container 3. When the first heat exchange container 2 or the second heat exchange container 3 is installed in place, the main heat source 10 contacts it and provides a heat source of the corresponding mode.

[0046] The first sealing cover 5 and the second sealing cover 6 are respectively adapted to and used to seal the first heat exchange container 2 or the second heat exchange container 3. When the first heat exchange container 2 or the second heat exchange container 3 is installed in place, the first sealing cover 5 or the second sealing cover 6 is connected to the shell 1. Both the first sealing cover 5 and the second sealing cover 6 are provided with air outlets 7 that connect the inside and outside.

[0047] The drive mechanism 8 is electrically connected to the electronic control module 18 and is used to drive the stirrer 4 inside the second heat exchange container 3 that is installed in place to rotate.

[0048] The locking mechanism 9 is used to circumferentially limit and lock the second heat exchange container 3 and the second sealing cover 6 when they are connected and move toward the housing 1 to a distance less than a set threshold L.

[0049] This invention utilizes a mature electric rice cooker heating shell 1 combined with different heating modes. Different inner pots and lids are used according to different processing requirements to achieve cooking or drying of food. This reduces equipment costs while achieving dual food processing functions. Furthermore, a locking mechanism 9 is added to the second heat exchange container 3 and the second sealing lid 6 for circumferential locking control. When the distance between the second sealing lid 6 and the shell 1 is less than a set threshold L, the locking mechanism 9 is activated to circumferentially limit and lock the connection between the second heat exchange container 3 and the second sealing lid 6. This ensures that the consumer must maintain a distance from the set threshold L of the shell 1 before opening the second heat exchange container 3 and the second sealing lid 6 to expose the dried or composted food. This prevents the materials or odors from drying or composting from contaminating the shell 1 or its surrounding environment, maintaining the cleanliness of the environment where the shell 1 is located. Therefore, this heating food processor can simultaneously possess both food drying and cooking modes.

[0050] The locking mechanism 9 includes a self-locking component 901 installed on the second sealing cover 6 for circumferentially limiting and fixing the second heat exchange container 3, and a distance-limiting electrical connection component 902 for controlling the automatic opening and closing of the self-locking component 901. When the distance between the second sealing cover 6 and the housing 1 is less than a set threshold L, the distance-limiting electrical connection component 902 controls the self-locking component 901 to be energized to circumferentially lock the second sealing cover 6 and the second heat exchange container 3. When the distance between the second sealing cover 6 and the housing 1 is greater than the set threshold L, the self-locking component 901 is de-energized and unlocked.

[0051] The distance-limiting electrical connection component 902 consists of a ranging module and a relay 9021. The ranging module is composed of a controller 9022 installed on the second sealing cover 6 and two Bluetooth ranging modules 9024 respectively installed on the second sealing cover 6 and the housing 1. The controller 9022 controls the relay 9021 according to the distance data, and the relay 9021 controls the power supply 9023 of the self-locking component 901.

[0052] The second sealing cover 6 is recessed inward and has a guide groove 601. The periphery of the second heat exchange container 3 is integrally formed with a limiting block 301. After the second heat exchange container 3 is connected to the second sealing cover 6, the limiting block 301 moves to the side of the guide groove 601. The self-locking component 901 is a push-pull solenoid valve installed on the second sealing cover 6. The push-pull solenoid valve includes a coil 9011 electrically connected to a power supply 9023 through the distance limiting electrical connection component 902, and an iron core 9012 movably installed in the coil 9011 through a corresponding elastic element 9013. The side of the guide groove 601 is provided with a corresponding through hole. When the coil 9011 is energized, the coil 9011 generates a magnetic force to form a linear thrust that pushes the iron core 9012 outward and inserts it into the through hole. The elastic element 9013 is compressed, and the limiting block 301 is then limited and fixed between the iron core 9012 and the guide groove 601.

[0053] The locking mechanism 9 of the present invention consists of a self-locking component 901 for circumferentially limiting and fixing the second heat exchange container 3, and a distance-limiting electrical connection component 902 for controlling the automatic opening and closing of the self-locking component 901. The Bluetooth proximity switch, or Bluetooth ranging module 9024 or UWB module with integrated ranging function in the distance-limiting electrical connection component 902 senses the distance between the second sealing cover 6 and the housing 1. The Bluetooth proximity switch or controller 9022 controls the relay 9021 according to the distance data, and then controls the power supply 9023 of the self-locking component 901 to be connected. After the power supply 9023 is connected to the coil 9011, the iron core 9012 is inserted into the through hole of the second sealing cover 6 under the linear thrust formed by the magnetic force generated by the coil 9011, thereby circumferentially fixing the second sealing cover 6 and the second heat exchange container 3. Within the usage range of the set threshold L, the second sealing cover 6 and the second heat exchange container 3 cannot be opened manually. They can only be opened manually after the automatic power is cut off and unlocked outside the limited distance, ensuring the limitation of use and practical effect.

[0054] The second sealing cover 6 is also provided with a display component 11 for determining whether the self-locking component 901 is locked or not. The display component 11 is an indicator light 1101 connected to the power supply 9023 via a trigger switch 1102. The trigger switch 1102 is installed on the coil 9011. When the coil 9011 is electromagnetically attracted, the iron core 9012 is moved into place and the iron core 9012 touches the trigger switch 1102, the indicator light 1101 lights up; otherwise, the indicator light 1101 is off.

[0055] This invention further includes a display component 11 based on the self-locking component 901. A trigger switch 1102 electrically connected to the display light 1101 is installed on the coil 9011. When the self-locking component 901 is activated, the iron core 9012 moves into position and touches the trigger switch 1102 to connect the power supply 9023 and the trigger switch 1102. This visually reminds the consumer that the second sealing cover 6 and the second heat exchange container 3 are circumferentially locked. That is, the display component 11 visually determines whether the locking mechanism 9 is activated, further preventing accidental opening of the second sealing cover 6 in the usage space and ensuring cleanliness during use. Furthermore, the display component 11 can only display the information when the self-locking component 901 is in position. If the second sealing cover 6 and / or the second heat exchange container 3 are not connected and are close to the housing 1, they will not be triggered, thereby saving energy and ensuring practicality.

[0056] The second sealing cover 6 and the corresponding side of the housing 1 are provided with corresponding metal magnetic contacts 12. The power supply 9023 is a rechargeable battery and is electrically connected to the metal magnetic contacts 12 on the second sealing cover 6. When the second sealing cover 6 is connected to the housing 1, the rechargeable battery is charged.

[0057] The drive mechanism 8 is installed inside the second sealing cover 6. The drive mechanism 8 includes a drive motor 801 and a connector 802 fixedly installed at the output shaft end of the drive motor 801. A corresponding bearing seat 803 is fixedly installed on the inner bottom of the second heat exchange container 3. A corresponding connecting seat 804 is rotatably installed through the bearing seat 803. The stirrer 4 is integrally formed and fixedly connected to the connecting seat 804. An upwardly extending connecting shaft 805 is fixedly installed on the top of the connecting seat 804. After the second heat exchange container 3 and the second sealing cover 6 are installed in place in sequence, the connecting shaft 805 is fixedly connected to the connector 802.

[0058] Installing the drive motor 801 inside the second closed cover 6 can isolate the drive mechanism 8 and the main heat source 10, preventing the main heat source 10 from affecting the drive mechanism 8 and further ensuring the practical effect of the present invention.

[0059] The first sealing cover 5 is detachably mounted with a corresponding sealing plate 14 on the side facing the first heat exchange container 2, and a sealing ring 15 is detachably sleeved around the periphery of the sealing plate 14. The sealing plate 14 is evenly distributed with a plurality of air guide holes that communicate with the air outlet 7. After the first heat exchange container 2 and the first sealing cover 5 are installed in place, the sealing ring 15 is pressed together to form a seal on the first heat exchange container 2.

[0060] A sealing ring 15 is detachably installed on the side of the second sealing cover 6 facing the second heat exchange container 3. After the second heat exchange container 3 and the second sealing cover 6 are connected, the sealing ring 15 is pressed between the second sealing cover 6 and the second heat exchange container 3, forming a seal for the second heat exchange container 3. A corresponding air guide hole is provided on the side of the second sealing cover 6 facing the second heat exchange container 3, and the air guide hole is connected to the air outlet 7 through a corresponding exhaust channel and a filter mechanism 16. A corresponding temperature and humidity detection module 17 is also provided on the side of the second sealing cover 6 facing the second heat exchange container 3. The filter mechanism 16 includes an exhaust fan 1601 and an adsorption filter element 1602 arranged sequentially in the exhaust channel. The gas in the second heat exchange container 3 is discharged after the adsorption filter element 1602 adsorbs odors. The drive mechanism 8, the exhaust fan 1601, and the temperature and humidity detection module 17 are electrically connected to the electronic control module 18 through a metal magnetic contact 12.

[0061] This invention adapts different first sealing covers 5 and second sealing covers 6 to the first heat exchange container 2 and the second heat exchange container 3. Both the first sealing cover 5 and the second sealing cover 6 are equipped with corresponding sealing rings 15 to ensure internal sealing when connected to their respective inner liner. Furthermore, the second sealing cover 6 is equipped with components such as a filtration mechanism 16 and a temperature and humidity detection module 17 required for drying or composting, thus providing the necessary equipment for drying and composting. Additionally, corresponding metal magnetic contacts 12 are provided on the side of the second sealing cover 6 opposite to the shell 1. When the second sealing cover 6 and the first sealing cover 5 are connected to the shell, the drive mechanism 8, the filtration mechanism 16, and the temperature and humidity detection module 17 are electrically connected via the metal magnetic contacts 12 to ensure practicality.

[0062] Because the two processing functions have different taste and hygiene issues, the raw materials used for composting or drying in this equipment must be relatively clean food scraps such as vegetable leaves, leftover rice, fruit peels, eggshells, and tea dregs produced on the same day, rather than leftovers with soup. The substances produced by drying or composting are clean, and the taste is filtered by the filter mechanism 16, so no other unpleasant tastes will be produced. Furthermore, the inner pot and the lid are matched and locked together, so they will not have any adverse effects on the hygiene and environment near the shell 1. Therefore, there will be no discomfort in using the steaming mode.

[0063] Example 2

[0064] refer to Figure 9-12The difference between this embodiment and Embodiment 1 is that: the drive mechanism 8 is installed inside the housing 1, the drive mechanism 8 includes a drive motor 801 and a connector 802 fixedly installed at the output shaft end of the drive motor 801, a corresponding bearing seat 803 is fixedly installed on the inner bottom of the second heat exchange container 3, and a corresponding connecting seat 804 is rotatably installed through the bearing seat 803, and the stirrer 4 is integrally formed and fixedly connected to the connecting seat 804; the bearing seat 803 is a bidirectional bearing seat, and after the second heat exchange container 3 and the second sealing cover 6 are installed in place in sequence, the shaft on the bidirectional bearing seat is fixedly connected to the connector 802.

[0065] An isolation cover 13 for isolating heat sources is fixedly installed on the housing 1 inside the heat exchange cavity 101. The main heat source 10 is installed inside the isolation cover 13. The drive motor 801 and the electronic control module 18 are installed in the receiving cavity formed by the isolation cover 13 and the housing 1.

[0066] The present invention installs the drive mechanism 8 for driving the stirrer 4 inside the second heat exchange container 3 inside the housing 1, and uses the isolation cover 13 to isolate the main heat source 10 and the drive mechanism 8, thereby effectively protecting the drive mechanism 8.

[0067] It should be noted that this embodiment is implemented in the same way as the first embodiment in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in the first embodiment.

[0068] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
