Description

Technical Field

[0001] The present invention relates to the field of stoves, and in particular to an integrated stove. Background Art

[0002] An integrated stove is a combined kitchen appliance that combines a stove, range hood, and cooking device. Examples include Chinese utility model patents ZL202122910382.X (authorization publication number CN216557216U), ZL202122811984.X (authorization publication number CN216557213U), and ZLCN216557213U (authorization publication number CN216521867U). When the cooking device and stove of an integrated stove are turned on simultaneously, heat in the cooking cavity transfers upward while heat generated by the stove's burner transfers downward, causing heat accumulation in the center of the integrated stove. This can overheat the operating environment of the electrical components within the stove, shortening their service life.

[0003] When a conventional cooking device is finished and the user opens the door, steam and hot air from the inner pot escape directly onto the user, posing a risk of burns and affecting the user's experience. Furthermore, existing techniques typically employ an additional fan system to dissipate heat from the interior of the integrated stove, as exemplified by Chinese utility model patent number ZL202022216967.7 (authorization publication number CN214370372U). However, adding an additional fan system increases the overall manufacturing cost of the device. Furthermore, given the limited space within the integrated stove, adding a fan system can complicate the internal structure of the stove and reduce its reliability. Furthermore, the fan system's air inlet is normally open and cannot be closed. Therefore, in relatively humid environments like kitchens, moisture can enter the stove through the fan system. Especially for integrated stoves with a steaming function, when the cooking device door is opened, a large amount of steam is inevitably drawn into the fan system and the stove, impacting the lifespan of the internal electrical components and posing a potential safety hazard. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide an integrated stove based on the existing technology, which can prevent the steam and hot air in the inner pot from directly spraying the user when the door is opened after cooking.

[0005] The second technical problem to be solved by the present invention is to provide an integrated stove that can achieve internal heat dissipation without adding an additional fan system in response to the existing technology.

[0006] The technical solution adopted by the present invention to solve the first technical problem is: an integrated stove, comprising:

[0007] case;

[0008] A cooking unit is located in the housing and comprises an inner pot with an opening at the front and a door covering the opening of the inner pot;

[0009] A cooker unit is located in the housing and is disposed above the cooking unit;

[0010] The oil fume extraction unit is located in the housing and is arranged behind the cooking unit, and comprises a bellows and a fan installed in the bellows, and is characterized in that it further comprises:

[0011] An interlayer is provided between the stove unit and the cooking unit;

[0012] a first air inlet, provided on the front of the housing and located above the inner pot of the cooking unit;

[0013] The exhaust channel is arranged in the interlayer along the front-to-back direction, and the front end thereof is in fluid communication with the first air inlet and the rear end thereof is in fluid communication with the air inlet on the wind box.

[0014] Furthermore, when cooking is completed and the door of the cooking unit is opened, the opening of the inner pot is fluidically connected to the first air inlet.

[0015] The technical solution adopted to further solve the second technical problem is as follows: an electrical component that generates heat during operation is installed in the interlayer, and a second air inlet for connecting the outside world with the interlayer is opened on the front of the shell, and the interlayer is communicated with the inner cavity of the bellows.

[0016] Furthermore, during cooking, the first air inlet is closed and the second air inlet is opened. When cooking is complete and the cooking unit door is open, the first air inlet is opened and the second air inlet is closed. Thus, during cooking, the fan's negative pressure allows cool air from the outside to be drawn into the interlayer through the second air inlet, dissipating heat from the electrical components installed therein and preventing excessive operating temperatures. This also prevents residual heat from the stove unit and cooking unit from accumulating in the interlayer, thus preventing the internal temperature of the integrated stove from rising. At the end of cooking, the fan's negative pressure draws away steam and hot air escaping from the inner pot when the door is opened, preventing them from being directed at the user and from entering the interlayer through the second air inlet. This demonstrates that the present invention eliminates the need for a separate fan system; the fan in the fume extraction unit can achieve both of these functions.

[0017] Furthermore, the first air inlet and the second air inlet extend in the left-right direction respectively and are arranged side by side in an upper and lower direction with a spacing therebetween, and further include a control component for controlling the opening and closing of the first air inlet and the second air inlet. The control component can realize the opening and closing control of the first air inlet and the second air inlet.

[0018] Furthermore, the control assembly includes a flap and an elastic reset member that are arranged on the front surface of the housing and rotate up and down in the left and right directions.

[0019] In the cooking state, there is a front-to-rear gap between the upper end of the above-mentioned flap and the above-mentioned second air inlet along the length direction, thereby opening the second air inlet; the lower end of the flap covers the above-mentioned first air inlet and is clamped between the front face of the shell and the upper end of the above-mentioned door body, thereby closing the first air inlet; the above-mentioned elastic return member is compressed so that the lower end of the above-mentioned flap has a tendency to flip forward so that its upper end covers the above-mentioned second air inlet, so that when the door is opened, the lower end of the flap flips forward under the action of the elastic force of the elastic return member to open the first air inlet, and at the same time the upper end of the flap flips backward to close the second air inlet.

[0020] Furthermore, the front of the housing has an air inlet plate that is vertically arranged and extends left and right. The first and second air inlets are respectively provided on the air inlet plate, with the second air inlet located above the first air inlet. The air inlet plate has a guide rib protruding forward along its length, and the guide rib is located between the first and second air inlets. The middle portion of the back of the flap along its width always abuts against the guide rib, and the flap can be flipped up and down with the guide rib as the center to cover one of the first and second air inlets. In this way, the first and second air inlets can be opened and closed by flipping the flap up and down relative to the guide rib.

[0021] Furthermore, the upper end of the air inlet plate is inclined forward from top to bottom along the length direction and is provided with the second air inlet, while the lower end of the air inlet plate extends vertically and is provided with the first air inlet. The upper end of the back of the flap is an upper shielding surface corresponding to and used to shield the second air inlet, while the lower end of the back of the flap is a lower shielding surface corresponding to and used to shield the first air inlet. In the cooking state, both the upper and lower shielding surfaces of the back of the flap extend vertically. In this way, in the cooking state, the lower shielding surface of the flap shields the first air inlet (the first air inlet is closed), while a front-to-rear gap is formed between the upper shielding surface and the second air inlet (the second air inlet is open). When cooking is completed and the door is opened, the upper shielding surface of the flap shields the second air inlet (the second air inlet is closed), while a front-to-rear gap is formed between the lower shielding surface and the first air inlet (the first air inlet is open).

[0022] Furthermore, the upper end of the air inlet plate rises forward along its length to form an outlet boss that tilts forward from top to bottom. The second air inlet is located on the front face of this outlet boss, and the edge of the front lower end of this outlet boss forms the aforementioned guide rib. This not only facilitates the inclined placement of the second air inlet on the air inlet plate, but also enables the flap to better control the opening and closing of the first and second air inlets during its rotation relative to the guide rib.

[0023] Furthermore, the lower end of the flap is bent rearward along its length to form a receiving groove on its front side for the upper end of the door body to engage, and the lower shielding surface is formed on its back side. In the cooking state, the flap is arranged vertically, and its front side is flush with the front side of the door body. This allows the control assembly to better maintain the first air inlet closed and the second air inlet open through the door body in the cooking state. When the door body is opened, the flap can quickly move under the action of elastic force to open and close the first air inlet. In addition, the flap can better rotate relative to the guide rib to control the opening and closing of the first and second air inlets.

[0024] Furthermore, a sealing ring is provided on the upper shielding surface of the flap. When cooking is completed and the door of the cooking unit is opened, the sealing ring is sandwiched between the upper end of the flap and the edge of the second air inlet, thereby enabling the upper shielding surface to better shield the second air inlet.

[0025] A sealing strip is provided on the lower shielding surface of the above-mentioned flap. In the cooking state, the sealing strip is clamped between the lower end of the above-mentioned flap and the lower end of the air inlet plate and shields the above-mentioned first air inlet, so that the lower shielding surface can better shield the first air inlet.

[0026] Furthermore, hinged seats are provided at the left and right ends of the back of the flap, each hinged seat being rotatably connected to the housing via a rotating shaft. Furthermore, a torsion spring and a damper are mounted on the rotating shaft on at least one side, the torsion spring serving as the elastic return element. This ensures the flap can be stably rotatably mounted on the housing, and allows for more stable opening and closing of the first and second air inlets.

[0027] Furthermore, the cross-sectional size of the exhaust duct decreases from front to back, and the inner bottom surface of the exhaust duct slopes downward from front to back. Water guides are protruding from the upper edge of the inner bottom surface of the exhaust duct. The water guides extend in the front-to-back direction and are spaced apart in the left-to-right direction. The spacing between adjacent water guides along the inner bottom surface of the exhaust duct increases as the width of the inner bottom surface of the exhaust duct increases. The provision of the water guides not only promotes the condensation of steam in the exhaust duct, but also allows the resulting condensed water to flow into the wind box under the guidance of the water guides and drip onto the oil collection plate below the fan, where it is collected in the oil collection box through the oil collection plate.

[0028] Furthermore, a guide bar is protruding from the upper edge of the inner top surface of the exhaust duct. The guide bars extend in the front-to-back direction and are spaced apart in the left-to-right direction. The spacing between adjacent guide bars along the inner top surface of the exhaust duct increases as the width of the inner top surface of the exhaust duct increases. Furthermore, the guide bars are staggered with the water guide bars. The guide bars not only better guide steam and hot air toward the air inlet of the bellows, but also promote condensation of steam. The resulting condensed water drips onto the inner bottom surface of the exhaust duct and, guided by the water guide bars, flows toward the air inlet of the bellows.

[0029] Furthermore, a flat exhaust pipe is disposed above the inner pot of the cooking unit. The inner cavity of the exhaust pipe constitutes the exhaust passage. The front end cover of the exhaust pipe is connected to the first air inlet, which is provided on the front plate of the bellows. The rear end cover of the exhaust pipe is connected to the air inlet. This allows for better fluid communication between the front end of the exhaust passage and the first air inlet, while also allowing for better fluid communication between the rear end of the exhaust passage and the first air inlet.

[0030] Furthermore, the top of the bellows has a top plate that is inclined forward from top to bottom, and a guide port is provided on the top plate for connecting the interlayer with the inner cavity of the bellows. The guide port enables the interlayer and the inner cavity of the bellows to be connected.

[0031] Compared with the prior art, the advantages of the present invention are that a first air inlet is provided on the front of the shell, a mezzanine is provided between the stove unit and the cooking unit, an exhaust channel is provided in the mezzanine, the front port of the exhaust channel is fluidically connected to the above-mentioned first air inlet, and the rear port is fluidically connected to the air inlet on the above-mentioned bellows.

[0032] When cooking is finished and the door of the cooking unit is open (at this time, the fan of the range fumes unit is still in working state), the opening of the inner pot is fluidly connected to the first air inlet. In this way, under the suction force of the fan of the range fumes unit, the steam and hot air escaping from the inner pot can pass through the first air inlet and be sucked into the exhaust channel, and then be sucked into the fan through the exhaust channel and discharged outside, thereby preventing the steam and hot air escaping from the inner pot from directly spraying on the user, thereby improving the user experience.

[0047] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0048] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0049] like Figures 1 to 14 As shown, an integrated stove includes a housing 1, housing a cooking unit 2, a cooktop unit 7, and an oil fume extraction unit. In this embodiment, the cooking unit 2 has steaming and baking functions, such as a steam oven. Furthermore, the cooking unit 2 has an inner pot 21 with an opening at the front and a door 23 covering the opening of the inner pot 21. The cooktop unit 7 is disposed above the cooking unit 2, and the oil fume extraction unit 3 is disposed behind the cooking unit 2 and includes a bellows 31 (in this embodiment, the bellows 31 shares a back plate with the housing 1) and a fan (not shown) installed in the bellows 31.

[0050] Further, if Figure 2 and Figure 4 As shown, a sandwich 60 is provided between the cooker unit 7 and the cooking unit 2, and a first air inlet 12 is provided on the front of the housing 1, and the first air inlet 12 is located above the inner pot 21 of the cooking unit 2. An exhaust passage 50 is provided in the sandwich 60 along the front-to-back direction, and the front end of the exhaust passage 50 is in fluid communication with the first air inlet 12 and the rear end is in fluid communication with the air inlet 32 ​​on the bellows 31. In this way, when cooking is completed and the door 23 of the cooking unit 2 is opened (as shown in FIG. 2 ), the cooking unit 2 is opened. Figure 7 and Figure 8 As shown, at this time, the fan of the range fumes extraction unit 3 is still in working condition), and the opening of the inner tank 21 is fluidly connected with the first air inlet 12. In this way, under the suction force of the fan of the range fumes extraction unit 3, the steam and hot air escaping from the inner tank 21 can pass through the first air inlet 12 and be sucked into the exhaust channel 50, and then be sucked into the fan through the exhaust channel 50 and discharged outside, thereby preventing the steam and hot air escaping from the inner tank 21 from being directly sprayed onto the user, thereby improving the user experience.

[0051] Further, if Figure 2 and Figure 4 As shown, the interlayer 60 is also equipped with electrical components that generate heat during operation (for example, the power supply box of the cooker unit 7, the display panel, etc.), and the front of the housing 1 is also provided with a second air inlet 13 for connecting the outside with the interlayer 60, and the interlayer 60 is in communication with the inner cavity of the bellows 31. Figure 3 As shown, in the cooking state, the first air inlet 12 is closed and the second air inlet 13 is opened, as shown in FIG. Figure 9 As shown, when cooking is complete and the door 23 of the cooking unit 2 is open, the first air inlet 12 is open and the second air inlet 13 is closed. In this way, under the negative pressure of the fan, cool air from the outside is drawn into the interlayer 60 through the second air inlet 13, dissipating heat from the electrical components installed in the interlayer 60 and preventing excessive operating temperatures. This also prevents residual heat from the operation of the cooktop unit 7 (transferred downward) and the cooking unit 2 (transferred upward) from accumulating in the interlayer 60, thus preventing the internal temperature of the integrated stove from rising. At the end of cooking, the negative pressure of the fan draws away steam and hot air that escapes from the inner pot 21 when the door is opened, preventing them from being directly sprayed onto the user. Furthermore, this prevents steam and hot air from entering the interlayer 60 through the second air inlet 13 (which could affect the electrical components therein). This demonstrates that the present invention eliminates the need for a separate fan system; the fan of the range fume extraction unit 3 can achieve both of these functions.

[0052] Furthermore, the first air inlet 12 and the second air inlet 13 extend in the left-right direction, respectively, and are arranged in parallel and spaced apart in the vertical direction. The control component 4 is further included to control the opening and closing of the first air inlet 12 and the second air inlet 13. The opening and closing control of the first air inlet 12 and the second air inlet 13 can be achieved through the control component 4. In this embodiment, the second air inlet 13 is formed by an arrangement of second air inlet holes 131 spaced apart in the left-right direction. Each second air inlet hole 131 is an elliptical hole extending up and down, thereby playing a role in combing the airflow, so that the external cold air can smoothly enter the interlayer 60 through the second air inlet 13. The first air inlet 12 is formed by an arrangement of first air inlet holes 121 spaced apart in the left-right direction. The first air inlet holes 121 are all long strip holes extending left and right. While guiding the airflow, they can also avoid the formation of excessive condensation water at the first air inlet 12.

[0053] Specifically, in this embodiment, the control assembly 4 includes a flap 41 and an elastic return member 43 that are arranged on the front of the housing 1 and rotate up and down in the left-right direction. In the cooking state, there is a front-to-back gap (such as 43) between the upper end of the flap 41 and the second air inlet 13 along the length direction. Figure 3As shown, the second air inlet 13 is opened. The lower end of the flap 41 covers the first air inlet 12 and is clamped between the front surface of the housing 1 and the upper end of the door body 23, thereby closing the first air inlet 12. The elastic return member 43 is compressed, causing the lower end of the flap 41 to flip forward, with its upper end covering the second air inlet 13. When the door is opened, the elastic force of the elastic return member 43 causes the lower end of the flap 41 to flip forward, opening the first air inlet 12, while the upper end of the flap 41 flips backward, closing the second air inlet 13.

[0054] Further, if Figure 4 and Figure 14 As shown, the front of the housing 1 has a vertically arranged air inlet plate 111 extending horizontally. The first air inlet 12 and the second air inlet 13 are respectively provided on the air inlet plate 111, with the second air inlet 13 located above the first air inlet 12. The air inlet plate 111 has a guide rib 15 protruding forward along its length. The guide rib 15 is located between the first air inlet 12 and the second air inlet 13. The back of the flap 41, along its width, always abuts against the guide rib 15 at its center. The flap 41 can be flipped up and down about the guide rib 15 to cover either the first air inlet 12 or the second air inlet 13. Thus, the first air inlet 12 or the second air inlet 13 can be opened and closed by flipping the flap 41 up and down relative to the guide rib 15.

[0055] Preferably, the upper end of the air inlet plate 111 is inclined forward from top to bottom along its length and defines the second air inlet 13, while the lower end of the air inlet plate 111 extends vertically and defines the first air inlet 12. The upper end of the back of the flap 41 serves as an upper shielding surface 41a corresponding to and shielding the second air inlet 13, while the lower end of the back of the flap 41 serves as a lower shielding surface 41b corresponding to and shielding the first air inlet 12. In the cooking state, both the upper shielding surface 41a and the lower shielding surface 41b of the back of the flap 41 extend vertically. Thus, in the cooking state, the lower shielding surface 41b of the flap 41 shields the first air inlet 12 (the first air inlet 12 is closed), while a front-to-rear gap is formed between the upper shielding surface 41a and the second air inlet 13 (the second air inlet 13 is open). When cooking is finished and the door 23 is open, the upper shielding surface 41a of the flap 41 shields the second air inlet 13 (the second air inlet 13 is closed), while a front-to-rear gap is formed between the lower shielding surface 41b and the first air inlet 12 (the first air inlet 12 is open). Further preferably, the upper end of the air inlet plate 111 bulges forward along its length to form an air outlet boss 14 that protrudes forward and tilts from top to bottom. The second air inlet 13 is located on the front face of the air outlet boss 14, and the front lower edge of the air outlet boss 14 constitutes the guide rib 15. On the one hand, it is convenient to realize the inclined setting of the second air inlet 13 on the air inlet plate 111 , and on the other hand, it enables the flap 41 to better control the opening and closing of the first air inlet 12 and the second air inlet 13 during the flipping process relative to the guide rib 15 .

[0056] Furthermore, the lower end of the flap 41 is bent rearwardly along its length, forming a receiving recess 411 on its front face for receiving the upper end of the door body 23, and forming the lower shielding surface 41b on its rear face. In the cooking mode, the flap 41 is vertically disposed, and its front face is flush with the front face of the door body 23. In this embodiment, the front face of the flap 41 is also flush with the front face of the control panel 8 located above it. This allows the control assembly 4 to be more effectively maintained in the closed position of the first air inlet 12 and the open position of the second air inlet 13 via the door body 23 during cooking. When the door body 23 is opened, the flap 41 is quickly elastically actuated to open and close the first and second air inlets 12 and 13. Furthermore, the flap 41 can be more effectively rotated relative to the guide rib 15 to control the opening and closing of the first and second air inlets 12 and 13.

[0057] Preferably, if Figure 5 and Figure 6As shown, a sealing ring 44 is provided on the upper shielding surface 41a of the flap 41. When cooking is completed and the door 23 of the cooking unit 2 is open, the sealing ring 44 is sandwiched between the upper end of the flap 41 and the edge of the second air inlet 13, thereby enabling the upper shielding surface 41a to better shield the second air inlet 13. A sealing strip 45 is provided on the lower shielding surface 41b of the flap 41. In the cooking state, the sealing strip 45 is sandwiched between the lower end of the flap 41 and the lower end of the air inlet plate 111, shielding the first air inlet 12, thereby enabling the lower shielding surface 41b to better shield the first air inlet 12.

[0058] Furthermore, the left and right ends of the back of the flap 41 are respectively provided with hinged seats 412, and each hinged seat 412 is respectively connected to the hinged seat 412 by a rotating shaft 42 ( Figure 5 The rotating shaft on the right is omitted) is rotatably connected to the above-mentioned shell 1, and a torsion spring and a damper 46 are installed on the rotating shaft 42 on the left. The torsion spring is the above-mentioned elastic return member 43, so that the flap 41 can be stably rotatably installed on the shell 1, and at the same time, the first air inlet 12 and the second air inlet 13 can be opened and closed more stably.

[0059] In this embodiment, an upper mounting plate 22 is horizontally arranged above the inner pot 21 of the cooking unit 2. A flat exhaust pipe 5 is arranged on the upper surface of the upper mounting plate 22. The inner cavity of the exhaust pipe 5 constitutes the exhaust channel 50. The front end cover of the exhaust pipe 5 is connected to the first air inlet 12. The air inlet 32 ​​is provided on the front plate 311 of the bellows 31, and the rear end cover of the exhaust pipe 5 is connected to the air inlet 32. This enables the front end of the exhaust channel 50 to be better in fluid communication with the first air inlet 12, while the rear end of the exhaust channel 50 is better in fluid communication with the first air inlet 12. Specifically, in this embodiment, Figure 10 、 Figure 11 as well as Figure 12 As shown, the exhaust pipe 5 is composed of an upper exhaust cover 5a and a lower exhaust cover 5b. Figure 14 As shown, the housing 1 includes an air inlet cover 11 located at the front. The air inlet cover 11 is a long square structure that extends in the left and right directions and opens toward the rear. The front side wall of the air inlet cover 11 constitutes the air inlet plate 111. The air inlet cover 11, the stove unit 7, the left and right side walls of the housing 1, the air box 31 of the range hood unit and the upper mounting plate 22 form the interlayer 60 (as shown in FIG. Figure 2 and Figure 8In addition, the top of the bellows 31 has a top plate 312 that slopes forward from top to bottom. A guide port 33 is formed on the top plate 312 to connect the interlayer 60 with the inner cavity of the bellows 31. The guide port 33 allows the interlayer 60 to communicate with the inner cavity of the bellows 31. In this embodiment, the guide port 33 is formed by a guide hole 331 disposed on the top plate 312.

[0060] Preferably, if Figure 10 、 Figure 11 as well as Figure 12 As shown, the cross-section of the exhaust duct 50 decreases from front to back. The inner bottom surface of the exhaust duct 50 slopes downward from front to back, and a water guide 51 is protruding from the upper edge of the inner bottom surface of the exhaust duct 50. The water guides 51 extend in the front-to-back direction and are spaced apart in the left-to-right direction. The spacing between adjacent water guides 51 along the inner bottom surface of the exhaust duct 50 increases as the width of the inner bottom surface of the exhaust duct 50 increases. The provision of the water guides 51 not only promotes the condensation of steam in the exhaust duct 50, but also allows the resulting condensed water to flow into the wind box 31 under the guidance of the water guides 51, dripping onto the oil collection plate below the fan, and then being collected in the oil collection box through the oil collection plate. A guide bar 52 is protruding from the upper edge of the inner top surface of the exhaust duct 50. The guide bars 52 extend in the front-to-back direction and are spaced apart in the left-to-right direction. The spacing between adjacent guide bars 52 along the inner top surface of the exhaust duct 50 increases as the width of the inner top surface of the exhaust duct 50 increases. Furthermore, the guide bars 52 are staggered with the water guide bars 51 (further promoting steam condensation). The guide bars 52 not only better direct steam and hot air toward the air inlet 32 ​​of the bellows 31, but also promote steam condensation. The resulting condensed water drips onto the inner bottom surface of the exhaust duct 50 and, guided by the water guide bars 51, flows toward the air inlet 32 ​​of the bellows 31.
