Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of integrated stoves, and in particular to an integrated stove with a fresh air purification system. Background Art
[0002] In Chinese cooking scenarios such as high-temperature stir-frying and frying, the kitchen environment faces the following problems: the oil fume particles generated by high-temperature cooking breed bacteria and produce odor after long-term accumulation; the oil mist combines with PM2.5 in the air to form inhalable particulate matter, which endangers respiratory health; the humid environment mixes with oil pollution to form heavy oil and humid air, and long-term inhalation will affect the health of the cook and increase the risk of lung cancer.
[0003] Therefore, it is necessary to deal with the oil smoke in the kitchen. The integrated stove is a kitchen appliance that integrates multiple functions such as range hood, gas stove, disinfection cabinet, storage cabinet, etc. It has the advantages of saving space, good oil smoke extraction effect, energy saving, low consumption and environmental protection.
[0004] However, the integrated stoves currently on the market can only extract the oil smoke, which reduces the amount of oil smoke inhaled by people in the kitchen. This method cannot completely solve the pollution problem of oil smoke. The oil smoke discharged in this way will continue to pollute the public flue, and will also pollute the air when discharged into the atmosphere, and even re-enter the human body through airborne transmission, causing damage to human health.
[0005] In addition, if the high-temperature air carrying oil smoke is directly discharged to the outside through the public flue, it will cause heat waste. Summary of the Invention
[0006] To address the shortcomings of the existing technology, the present application provides an integrated stove with a fresh air purification system. The integrated stove with a fresh air purification system of the present application is equipped with a (fresh air) adsorption purification system. In a kitchen environment with severe oil pollution, the oily air inside the kitchen is purified and discharged outdoors, reducing pollution to public flues and reducing damage to human health. In addition, in the present application, the heat exchange module can collect and reuse the waste heat of the oil smoke. The recovered heat energy is used to re-dry the adsorption plate (the adsorption plate is used to absorb humid air in the kitchen space), allowing the adsorption plate to quickly restore its adsorption effect, thereby keeping the kitchen space dry and preventing the humid environment from causing mold or breeding bacteria, which may affect the health of cooks.
[0007] The technical solution of this application is:
[0008] An integrated stove with a fresh air purification system includes an integrated stove body; the integrated stove body is provided with a diversion heat exchange module and an adsorption purification system; the integrated stove body includes an operating table, an integrated stove head, an integrated stove bottom and a fan; the diversion heat exchange module is arranged inside the integrated stove head, and is used to gather and guide the high-temperature oil smoke passing through to the adsorption purification system, and exchange heat with the high-temperature oil smoke to collect the residual heat of the oil smoke; the adsorption purification system is arranged inside the operating table, and includes an adsorption module and a purification module; the adsorption module is used to adsorb and dehumidify the humid air entering from the bottom of the integrated stove, and discharge it to the public flue through the fan; the purification module includes a condenser cavity, which is used to condense the high-temperature oil smoke entering from the integrated stove head; the purification module also includes a wastewater cavity and an oil filter, and the oil filter is arranged between the condenser cavity and the wastewater cavity, and is used to filter the condensed oil-water mixture; the wastewater cavity is used to collect the filtered wastewater and discharge it to the outside.
[0009] Compared with the existing technology, the integrated stove with fresh air purification system of the present application can not only purify and discharge oil smoke but also adsorb and purify the humid air inside the kitchen; the high-temperature oil smoke passes through the head of the integrated stove and is guided and the waste heat is collected by the heat conduction and heat exchange module before entering the condenser cavity of the purification module. The high-temperature oil smoke is condensed by the condenser, turning it into an oil-water mixture, and is filtered out through the oil filter net, and enters the wastewater cavity for storage and discharge; in addition, the humid air inside the kitchen enters the adsorption module through the bottom of the integrated stove, and turns into dry air and is discharged into the public flue; thereby reducing the pollution to the public flue and reducing the damage to human health, thereby creating a healthy, dry and comfortable kitchen environment.
[0010] As an optimization, in the aforementioned integrated stove with a fresh air purification system, the diversion and heat exchange module includes a set of guide plates and a heat exchanger; the guide plates near the two sides are densely distributed, while the guide plates near the middle are sparsely distributed. This structure is precisely designed based on the characteristics of high flow velocity on both sides and low flow velocity in the middle when oil smoke enters the integrated stove, so as to achieve an efficient oil smoke convergence and diversion effect; this differentiated spacing design is based on the principles of fluid mechanics, and optimizes the flow trajectory of oil smoke by forming pressure gradients in different areas; the dense guide plates on both sides slow down the high-velocity airflow at the edge by increasing local flow resistance, while the looser guide plates in the middle allow the lower-velocity central airflow to pass more smoothly, thus forming a balanced and streamlined flow profile; this design significantly improves the capture efficiency of high-temperature oil-containing smoke, reduces the dispersion of oil smoke, and ensures effective heat exchange and subsequent purification treatment; and actual test verification shows that compared with the design of uniformly distributed guide plates, this structural design has significant advantages in the oil smoke convergence and diversion effect. Furthermore, the distance between the guide plates near the sides is dm, and the distance between the guide plates near the center is DM, and DM is 1.5-2.5 times dm. In actual practice, this spacing design has a good convergence and diversion effect. Furthermore, DM is 2 times dm.
[0011] As an optimization, in the aforementioned integrated stove with a fresh air purification system, the guide heat exchange module further includes a fixed bracket, a movable bracket and an adaptive sliding structure; the guide plate is a foldable structure, the fixed end of the guide plate is connected to the fixed bracket, and the movable end of the guide plate is connected to the movable bracket; the adaptive sliding structure includes a mounting frame, a movable rod and a connecting rod; the mounting frame is mounted on the movable bracket, one end of the movable rod is hinged to the mounting frame, and the other end is slidably engaged with the strip groove on the connecting rod; the connecting rod is connected to the guide plate. This structure is based on the Bernoulli principle and can flexibly adjust the overall configuration of the foldable guide plate according to the dynamic changes in the direction of oil smoke entry; each guide plate adopts a foldable structure similar to an accordion, so that the rotation of the movable rod can drive the folding or unfolding of the guide plate; this adaptive adjustment optimizes the convergence and diversion performance of the guide plate, ensures that the oil smoke is efficiently guided to the adsorption purification system, and significantly improves the overall purification efficiency of the system.
[0012] As an optimization, in the aforementioned integrated stove with a fresh air purification system, the deflector has a raised surface. This structure can intercept and adsorb oil fume particles. Furthermore, an adsorption layer is provided on the deflector, further enhancing the adsorption effect of oil fume.
[0013] As an optimization, in the aforementioned integrated stove with a fresh air purification system, the adsorption module includes an adsorption chamber, an intake duct, a negative pressure chamber, and an exhaust duct. The adsorption chamber is provided with a pair of adsorption plates for adsorbing oil smoke and moisture from the air. One end of the negative pressure chamber is connected to the end face of the integrated stove body. One end of the intake duct is connected to the adsorption chamber, and the other end is connected to the negative pressure chamber. The exhaust duct is provided on the adsorption chamber for discharging the adsorbed air. The fan is connected to the negative pressure chamber. In this structure, moist air is drawn from the negative pressure chamber by the fan, enters the adsorption chamber through the intake duct, and is converted into dry air after passing through the adsorption plates and discharged.
[0014] As an optimization, in the aforementioned integrated stove with a fresh air purification system, a connecting pipe A is provided between the adsorption module and the purification module, with a control valve A installed on the connecting pipe; a connecting pipe B is provided between the adsorption module and the diversion heat exchange module, with a control valve B installed on the connecting pipe. With this structure, when the adsorption plate becomes moist after adsorption, the A and B control valves are opened, allowing the circulating gas in the heat exchanger to enter the adsorption chamber of the adsorption module from the diversion heat exchange module, flow through the adsorption plate, drying it again, and then enter the condenser chamber through the connecting pipe A. After condensation, it returns to the heat exchanger, thus achieving the self-drying function of the adsorption plate.
[0015] As an optimization, in the aforementioned integrated stove with a fresh air purification system, a check valve is provided on the negative pressure chamber to prevent oil smoke from flowing from the negative pressure chamber into the kitchen.
[0016] As an optimization, in the aforementioned integrated stove with a fresh air purification system, the material used to adsorb oil smoke on the adsorption plate is activated carbon. Activated carbon has a strong adsorption capacity and is non-toxic, making it both environmentally friendly and economical. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present application is further described below with reference to the accompanying drawings and examples, but is not intended to limit the present application. In the following examples, any content not described in detail or not shown in detail in the accompanying drawings is common knowledge in the art.
[0026] Example (see Figures 1 to 7 ):

[0028] In this embodiment, the diversion and heat exchange module 2 comprises a set of diversion plates 21 and a heat exchanger 22. The diversion plates 21 are densely distributed near the sides, while those near the center are sparsely distributed. This structure is precisely designed to address the high flow velocity of oil smoke entering the integrated stove, which occurs at the sides and is low in the center, achieving efficient oil smoke convergence and diversion.
[0029] In this embodiment, the distance between the guide plates 21 near the two sides is dm, and the distance between the guide plates 21 near the middle is DM, which is twice dm. Practical verification shows that this spacing design has a better convergence and diversion effect.
[0030] In this embodiment, the deflector heat exchange module 2 further includes a fixed bracket 23, a movable bracket 24, and an adaptive sliding structure 25. The deflector 21 is a foldable structure, with the fixed end of the deflector 21 connected to the fixed bracket 23, and the movable end of the deflector 21 connected to the movable bracket 24. The adaptive sliding structure 25 includes a mounting bracket 251, a movable rod 252, and a connecting rod 253. The mounting bracket 251 is mounted on the movable bracket 24, with one end of the movable rod 251 hinged to the mounting bracket 251 and the other end slidingly engaged with a strip groove 2531 on the connecting rod 253. The connecting rod 253 is connected to the deflector 21. This structure can fold or unfold the deflector 21 according to the direction of the incoming smoke by rotating the movable rod 251, thereby adaptively adjusting the overall structure of the deflector 21.
[0031] In this embodiment, the surface of the guide plate 21 is a convex structure, which can block and adsorb the oil smoke particles.
[0032] In this embodiment, an adsorption layer is provided on the guide plate 21. This structure further enhances the adsorption effect of oil smoke.

A pair of adsorption plates 315 are provided in the adsorption chamber 311 to absorb moisture from oil smoke and air. One end of the negative pressure chamber 313 is connected to the end face of the integrated stove body 1.

The exhaust pipe 314 is provided on the adsorption chamber 311 to discharge the adsorbed air. The fan 14 is connected to the negative pressure chamber 313. In this structure, the fan 14 draws humid air from the negative pressure chamber 313, which enters the adsorption chamber 311 through the intake pipe 312.

The circulating gas then enters the condenser chamber 321 through the connecting pipe A 4, condenses, and returns to the heat exchanger 22, thereby achieving the self-drying function of the adsorption plate 315.
[0035] In this embodiment, a check valve 8 is provided on the negative pressure chamber 313. The check valve 8 can prevent the smoke from flowing from the negative pressure chamber 313 into the kitchen.
[0036] In this embodiment, the material used to adsorb oil smoke on the adsorption plate 315 is activated carbon. Activated carbon has a strong adsorption capacity and is non-toxic, thus being both environmentally friendly and economical.
[0037] When the integrated stove with the fresh air purification system of this embodiment is in operation, high-temperature cooking fumes pass through the integrated stove head 12, are guided and waste heat is collected by the heat conduction and heat exchange module 2, and then enter the condenser cavity 321 of the purification module 32. The high-temperature cooking fumes are condensed by the condenser, turning them into an oil-water mixture. The waste water is filtered out through the oil filter 323 and enters the wastewater cavity 22 for storage and discharge. In addition, humid air inside the kitchen enters the adsorption module 31 through the negative pressure cavity 313 of the integrated stove bottom 13, and is converted into dry air and discharged into the public flue. When the adsorption plate 315 becomes humid after adsorption, the A control valve 5 and the B control valve 7 are opened, allowing the circulating gas in the heat exchanger 22 to enter the adsorption cavity 311 of the adsorption module 31 from the guide heat exchange module 2, flow through the adsorption plate 315, and return the adsorption plate 315 to a dry state. The circulating gas then enters the condenser cavity 321 through the A connecting pipe 4, and after condensation, returns to the heat exchanger 22, thus realizing the self-drying function of the adsorption plate 315.
