Description

Technical Field

[0001] This utility model relates to the field of indoor air environment balance and energy-saving technology, and in particular to an active balancing integrated energy-saving stove. Background Technology

[0002] As people's demand for indoor comfort and health continues to increase, the "multi-constant" system, as an integrated smart home solution, is gradually entering people's lives. However, when using traditional stoves, fuel combustion consumes a large amount of indoor oxygen, and the air introduced from the outside may have a temperature difference with the indoor air. In addition, the stove fire not only heats the cookware but also dissipates a large amount of heat to the outside of the cookware. The exhaust gas produced after fuel combustion also contains a large amount of heat, which will significantly interfere with the "constant oxygen and constant temperature" in the closed "multi-constant" indoor environment system and waste energy, which is not conducive to energy conservation and emission reduction. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of traditional stoves in the prior art, which will significantly interfere with the "constant oxygen, constant temperature" and other "multi-constant" indoor environmental systems and waste energy, this utility model provides an active balance integrated energy-saving stove.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an active balance integrated energy-saving stove, including a shell and a range hood. A stove platform is provided at the middle position of the upper end of the shell. A stove head heat exchanger is provided inside the stove platform. An upper box body is provided on the rear side of the upper end of the shell and communicates with the inner side of the shell. A lower box body is provided inside the shell and communicates with the upper box body. The range hood communicates with the upper box body or the lower box body depending on whether the exhaust method is upward or downward. A flue gas heat exchanger is provided inside the upper box body. An active air intake component is provided inside the shell body. The air intake end of the active air intake component is connected to the outside. The air outlet end of the active air intake component is connected to the air inlet end of the flue gas heat exchanger. The air outlet end of the flue gas heat exchanger is connected to the air inlet end of the stove head heat exchanger. The air outlet end of the stove head heat exchanger is aligned with the burner cap on the stove head.

[0005] When using the energy-saving stove, ignition is achieved by switching on the stovetop and adjusting the knobs. At the same time, the active air intake component actively sends outdoor air into the flue gas heat exchanger for initial heating. The flue gas heat exchanger is connected to the burner heat exchanger, which then sends the initially heated air into the burner heat exchanger for reheating. The heated air then enters the burner for combustion. The high-temperature exhaust gas after combustion exchanges heat with the flue gas heat exchanger in the upper casing before being collected and discharged by the exhaust fan.

[0006] Furthermore, to introduce outdoor air, the active air intake assembly includes a first air intake, a main air intake pipe, and air intake branch pipes. The first air intake is located on the housing and communicates with the outside. A telescopic pipe is provided between the main air intake pipe and the first air intake. An air intake filter is provided on the side of the telescopic pipe near the main air intake pipe. One or more air intake branch pipes are connected to the main air intake pipe. An air intake fan and a wind speed sensor are provided inside the air intake branch pipe. An air intake baffle is provided between the air intake fan and the wind speed sensor and is rotatably connected to the air intake branch pipe. A baffle motor for connecting with the air intake baffle is provided on the outer wall of the air intake branch pipe. An air intake distribution pipe is provided at the end of the air intake branch pipe away from the main air intake pipe. The air intake distribution pipe is connected to the air intake end of the flue gas heat exchanger through a heat exchanger interface.

[0007] The telescopic tube is designed for easy cleaning or replacement of the air intake filter; one or more air intake branch pipes are provided depending on the number of burners; the baffle motor controls the rotation of the air intake baffle, thereby controlling the opening or closing of the air intake branch pipe; the air intake fan is used to actively introduce outdoor air; the wind speed sensor is used to monitor the wind speed, thereby monitoring the working status of the air intake filter, air intake fan, air intake baffle, and baffle motor.

[0008] Furthermore, to facilitate observation of the working status of the intake filter, intake fan, and intake baffle, the main intake pipe and intake branch pipe are made of transparent tubing.

[0009] Furthermore, the flue gas heat exchanger includes multiple curved first heat exchange tubes. Each first heat exchange tube is connected to an air inlet pipe, and each first heat exchange tube is connected to a burner heat exchanger. Multiple heat collection plates are installed on the first heat exchange tubes. The arrangement density of the first heat exchange tubes and heat collection plates can be increased according to the heat collection requirements, thereby increasing the heat exchange effect.

[0010] Furthermore, the burner heat exchanger includes a heat collecting head arranged circumferentially along the burner cap. An annular distribution pipe is provided inside the heat collecting head. The annular distribution pipe has multiple second air inlets connected to each of the first air outlet pipes. The annular distribution pipe also has multiple second air outlet pipes facing the burner cap. To increase the heat exchange effect, the density and path of the second air outlet pipes can be increased.

[0011] Furthermore, the stove includes a stove panel, on which a switch and adjustment knob and a pot support are provided. The burner heat exchanger is located between the burner cap and the pot support. The stove panel has a second air inlet for connecting a second air inlet pipe. The system controller is installed below the stove panel and is electrically connected to the switch and adjustment knob, the active air intake component and the exhaust fan.

[0012] The system controller and switches, along with the adjustment knobs, synchronously switch on / off the burner, active air intake assembly, and range hood, and simultaneously adjust the burner's firepower, the active air intake assembly's air intake intensity, and the range hood's power.

[0013] Furthermore, an oil fume filter screen is provided on the front side of the upper housing, and an oil collection groove is provided on the lower side of the oil fume filter screen.

[0014] Furthermore, in order to provide an energy-saving stove with a downdraft exhaust method, the exhaust fan is located on one side of the lower casing, the air inlet of the exhaust fan is connected to the lower casing, and the air outlet of the exhaust fan is provided with an exhaust pipe.

[0015] This utility model also provides an active balanced integrated energy-saving stove with an upward exhaust method. The exhaust fan is provided on the upper side of the upper housing. The air inlet of the exhaust fan is connected to the upper housing. The air outlet of the exhaust fan is provided with an exhaust pipe.

[0016] The active balancing integrated energy-saving stove provided by this utility model has the following beneficial effects:

[0017] 1. The active air intake component controls and coordinates the amount of air intake from the outside, the amount of air consumed during fuel combustion in the stove, and the amount of exhaust gas discharged by the range hood through the system controller to achieve a balance among the three, thereby preventing the constant indoor environment of the enclosed space equipped with the "multi-constant" system from being disrupted by the use of the stove.

[0018] 2. The heat exchanger at the burner head recovers the heat emitted by the cookware and flame during fuel combustion, and the heat exchanger at the flue gas recovers the heat from the exhaust gas generated after fuel combustion. The air introduced from the outside by the active air intake component is preheated before entering the burner head to participate in fuel combustion, thereby reducing fuel consumption and saving energy. The energy-saving effect is more obvious when the outdoor air temperature is lower. Attached Figure Description

[0046] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0047] Example 1:

[0048] like Figure 1-11 As shown, this utility model discloses an active balancing integrated energy-saving stove with a bottom exhaust method, including a housing 1 and a range hood 6. A stove platform 5 is located at the middle of the upper end of the housing 1, and a stove head heat exchanger 4 is located on the stove platform 5. An upper box 13 and a lower box 16, which are connected to the inner side of the housing 1, are located on the rear side of the upper end of the housing 1. A lower box 16, which is connected to the upper box 13, is located inside the housing 1. The range hood 6 is located inside the housing 1.

An oil fume filter 14 is located on the front side of the upper box 13, and an oil collection trough 15 is located on the lower side of the oil fume filter 14.

[0049] The housing 1 is equipped with an active air intake component 2. The air intake end of the active air intake component 2 is connected to the outside. The air outlet end of the active air intake component 2 is connected to the air intake end of the flue gas heat exchanger 3 through the heat exchanger interface 211. The air outlet end of the flue gas heat exchanger 3 is connected to the air intake end of the burner heat exchanger 4. The air outlet end of the burner heat exchanger 4 is aligned with the burner cap 53 on the stove 5.

[0050] The active air intake assembly 2 includes a first air intake 21, a main air intake 24, and air intake branch pipes 25. An air intake hole 12 is provided on the housing 1. The first air intake 21 is located at the air intake hole 12 and communicates with the outside, facilitating the intake of fresh air into the room. A telescopic pipe 22 is provided between the main air intake 24 and the first air intake 21. An air intake filter 23 is provided on the side of the telescopic pipe 22 near the main air intake 24. Two air intake branch pipes 25 are connected to the main air intake 24. The number of air intake branch pipes 25 corresponds to the number of stove heads. Correspondingly, an intake fan 26 and a wind speed sensor 29 are installed inside the intake branch pipe 25. An intake baffle 27, rotatably connected to the intake branch pipe 25, is provided between the intake fan 26 and the wind speed sensor 29. A baffle motor 28 for connecting with the intake baffle 27 is provided on the outer wall of the intake branch pipe 25. An intake distribution pipe 210 is provided at the end of the intake branch pipe 25 away from the main intake pipe 24. A heat exchanger interface 211 is provided on the intake distribution pipe 210, which is connected to the intake end of the flue gas heat exchanger 3. The main intake pipe 24 and the intake branch pipe 25 are made of transparent tubes.

[0051] The flue gas heat exchanger 3 includes multiple curved first heat exchange tubes 32. Each first heat exchange tube 32 is connected to the air inlet distribution pipe 210 and a first air outlet pipe 34 is connected to the stove head heat exchanger 4. Multiple heat collection plates 33 are provided on the first heat exchange tubes 32.

[0052] The stove heat exchanger 4 is located between the burner cap 53 and the pot support 54, including a heat collection head 44 arranged around the burner cap 53. The heat collection head 44 is provided with an annular distribution pipe 42. The annular distribution pipe 42 is provided with a plurality of second air inlet pipes 41 that are respectively connected to each of the first air outlet pipes 34. The annular distribution pipe 42 is provided with a plurality of second air outlet pipes 43 that are arranged toward the burner cap 53.

[0053] The stove 5 includes a stove panel 51, on which a switch and adjustment knob 52 and a pot support 54 are provided. The stove head panel 51 is provided with a second air inlet 55 for connecting the second air inlet pipe 41. The system controller 56 is installed below the stove panel 51 and is electrically connected to the switch and adjustment knob 52, the active air intake component 2 and the range hood 6.

[0054] The exhaust fan 6 is similar to a regular exhaust fan, mainly including a motor, impeller, volute, etc. Its air inlet is connected to the connection port 17 on the lower box 16 to extract the exhaust gas collected by the upper box 13 through the lower box 16; its air outlet is connected to the exhaust pipe 61 through the exhaust hole 18 to discharge the exhaust gas into the flue.

[0055] Work process: When this active balance energy-saving stove needs to be used, turn on the switch and the adjustment knob 52. The baffle motor 28 corresponding to the switch and the adjustment knob 52 will start first, opening the corresponding air intake baffle 27. Then the corresponding air intake fan 26 will start, the corresponding burner on the stove 5 will ignite, and the exhaust fan 6 will start working.

[0056] Outdoor air enters the main intake pipe 24 through the intake hole 12, the first intake port 21, the telescopic pipe 22, and the intake filter 23 in sequence, then enters the intake branch pipe 25, and then enters the intake distribution pipe 210 through the corresponding intake fan 26 and intake baffle 27 in sequence. The air entering the intake distribution pipe 210 is evenly distributed to the first intake pipe 31 corresponding to the flue gas heat exchanger 3 through the heat exchange interface 211.

[0057] When the stove 5 is first ignited, the exhaust gas produced after combustion is drawn into the upper housing 13 by the exhaust fan 6 and begins to come into contact with the flue gas heat exchanger 3. The heat emitted from the cookware and the outer periphery of the flame then affects the burner heat exchanger 4. At this time, the temperature of the flue gas heat exchanger 3 and the burner heat exchanger 4 is not high, and the heating of the air in the flue gas heat exchanger 3 and the burner heat exchanger 4 is not significant. The air coming out of the first intake pipe 31 only passes through the first intake pipe 31, the first heat exchange pipe 32, and the first exhaust pipe 34 of the flue gas heat exchanger 3 in sequence, and the second intake pipe 41, the annular distribution pipe 42, and the second exhaust pipe 43 of the burner heat exchanger 4 before being sprayed onto the burner cap 53 to participate in fuel combustion. At this time, the energy-saving effect is not obvious.

[0058] After a short time, the high-temperature exhaust gas generated after fuel combustion heats the first heat exchange tube 32 through the heat collection plate 33. At the same time, the heat emitted from the pot and the outer periphery of the flame heats the heat collection head 44. At this time, the flue gas heat exchanger 3 and the stove heat exchanger 4 begin to preheat the air passing through them. When the preheated air participates in combustion, it can achieve energy-saving effect. The lower the outdoor air temperature, the more obvious the energy-saving effect.

[0059] The exhaust gas after combustion enters the lower box 16 through the upper box 13, and is discharged into the flue through the exhaust port 18 by the exhaust fan 6 via the exhaust fan 6 interface.

[0060] When the switch and adjustment knob 52 are turned up, the firepower of the stove 5 is increased, and the system controller 56 causes the intake fan 26 and the exhaust fan 6 to increase their speeds in sync, and vice versa, so as to ensure that the air intake, combustion volume and exhaust volume reach a dynamic balance, reducing the impact of using the stove on the indoor environment.

[0061] When the intake filter 23 is clogged, the intake fan 26 malfunctions and does not operate, or the intake damper 27 motor malfunctions and prevents the intake damper 27 from opening normally, the wind speed sensor 29 detects the abnormal airflow after the switch and adjustment knob 52 are turned on and sends a signal to the system controller 56. The alarm in the system controller 56 then sounds. At this time, the fault location can be easily found by observing the transparent intake main pipe 24 and intake branch pipe 25. If the system is in standby mode after the switch and adjustment knob 52 are closed, and the intake fan 26 continues to run due to a fault, or the intake damper 27 cannot close normally, the sensors contained in the intake fan 26 and intake damper 27 send a fault signal to the system controller 56, and the alarm in the system controller 56 sounds. The handling method is the same as above.

[0062] Flue gas heat exchanger 3 and stove head heat exchanger 4 are optional components. One or two can be installed depending on energy-saving requirements.

[0063] Example 2:

[0064] like Figure 12 , 13 As shown, the difference between this embodiment and embodiment one is mainly the location of the smoke exhaust. Embodiment two uses top smoke exhaust. This embodiment omits the lower housing 16 in embodiment one. The smoke exhaust fan 6 is located on the upper side of the upper housing 13. The air inlet of the smoke exhaust fan 6 is connected to the upper housing 13, and the air outlet of the smoke exhaust fan 6 is provided with a smoke exhaust pipe 61.
