Description

In order to enable the kitchen range to be assembled and disassembled with other cooking equipment more simply and quickly, the installation and maintenance channel is arranged behind the kitchen range. Fig. 2 is a schematic diagram of an integrated stove structure, as shown in fig. 2, in order to make the stove more beautiful, a water receiving box seat, an air duct cover plate and the like are arranged at the left position of the bottom shell of the stove, meanwhile, considering the problem of temperature rise of a fan, a heat dissipation fan is arranged at the middle position of the bottom shell of the stove (the direction marked in the figure is not limited, and only illustrative). After the air outlet of the heat dissipation fan is connected with the air duct cover plate, under the condition that the size of the air outlet of the heat dissipation fan is unchanged, most of heat can be discharged through a channel formed by the connecting position of the air outlet of the heat dissipation fan and the air duct cover plate due to the influence of wind speed and wind quantity, a small amount of dissipated heat can be discharged through the connecting position of the air outlet of the heat dissipation fan and the air duct cover plate, that is, wind in the heat dissipation fan cannot be discharged through the air duct cover plate in a relatively dispersive manner, because the wind quantity discharged at a place close to the air outlet of the heat dissipation fan is large, the wind speed is high, and more heat is taken away, so that a kitchen range close to the position can be in an environment with high temperature and fast air circulation around the flame of the kitchen range for a long time, and the heat efficiency of the kitchen range can be influenced.

Referring to fig. 3, fig. 3 is a schematic top view of an air duct structure according to an embodiment of the present application, where the air duct structure includes: a ventilation hood structure (1) and at least one space divider (2). The ventilation hood structure (1) can comprise an air inlet (11) and an air outlet (12), the air inlet (11) is connected with an air outlet channel (31) of the heat radiation fan (3), and at least one space partition piece (2) is arranged in the ventilation hood structure (1) so that the space of the ventilation hood structure (1) is partitioned into a plurality of heat radiation channels (4) which are parallel in the horizontal direction. Among the plurality of heat dissipation channels (4), the channel inlet section of the heat dissipation channel close to the air inlet (11) is smaller than the channel inlet section of the heat dissipation channel far away from the air inlet (11), and the channel inlet section of the heat dissipation channel corresponding to the air inlet (11) is smaller than the section of the air inlet (11).

Through set up space partition spare in the wind channel structure, form a plurality of heat dissipation channels, and through adjusting the relative size of the passageway import cross-section of every heat dissipation channel and the relative size of the passageway import cross-section of heat dissipation channel and air intake cross-section that corresponds with the air intake, make the hot-blast that blows out in the radiator fan can be discharged by dispersing in a plurality of heat dissipation channels, because hot-blast is dispersed, so hot-blast amount of wind can be reduced, the wind speed is reduced, the temperature around the cooking utensils also can not be too high, the speed of air circulation around the cooking utensils flame is reduced, and then reduce the influence that hot-blast produced to cooking utensils thermal efficiency.

In this embodiment, fig. 4 is a schematic diagram of an air duct structure provided in this embodiment, as shown in fig. 4, the whole ventilation hood structure (1) may be disposed on a device equipped with an air duct structure, the ventilation hood structure (1) may be formed by enclosing a side wall plate (13) and a cover plate (14), and an air inlet (11) and an air outlet (12) are disposed on the side wall plate (13). Wherein, the apron can enclose the side wall board and establish and form the space closing cap.

Alternatively, the cover plate and the side wall plate can be connected through screws, and can also be assembled together directly through welding. The materials of the cover plate and the side coaming can be aluminum alloy, stainless steel or galvanized steel plate materials. An air inlet and an air outlet can be formed in the side surrounding plate, the air inlet and the air outlet can be respectively formed in two opposite surfaces of the side surrounding plate, the air inlet is connected with an air outlet channel of the heat dissipation fan, and hot air can pass through the air outlet channel and the air inlet of the heat dissipation fan and then be discharged from the air outlet.

Through setting up apron and side coaming to set up air intake and air outlet respectively on the side coaming, can guide hot-blast arrival air outlet from the air intake like this, and discharge smoothly.

In an alternative embodiment, fig. 5 is a schematic diagram of a vertical distance between an air inlet and an air outlet of an air duct structure provided in this embodiment, as shown in fig. 5, a vertical distance H between the air outlet (12) and the air inlet (11) is smaller than a first preset distance, and at least one space partition member (2) exists in the ventilation hood structure (1) to partition a space in the ventilation hood structure (1) into a plurality of heat dissipation channels (4) parallel in a horizontal direction.

The air inlet shown in the figure is arranged at the right side of the ventilation hood structure, meanwhile, the area of the air outlet is larger than that of the air inlet, if the vertical distance H between the air outlet and the air inlet is smaller, the size of the air inlet is unchanged, and under the conditions that the wind speed of the air discharged from the air outlet channel of the heat dissipation fan is larger and the wind quantity is large, most of hot air can be directly discharged from the air inlet to the air outlet vertically, namely from the air outlet close to the right side, and a small amount of air can be dispersed to the air outlet close to the left side (the direction marked in the figure is not limited and is only illustrative).

Long time, the exhaust wind heat near the right side is high, the wind speed is fast, if a kitchen range is arranged near the air outlet near the right side, the air flow speed around the flame of the kitchen range is fast due to the influence of the exhaust hot wind, the temperature around the kitchen range is in a higher level for a long time, and the heat efficiency of the kitchen range can be influenced.

At this time, in order to split most of the hot air discharged from the air outlet near the right and discharge the hot air from the air duct structure in a relatively dispersed manner, at least one space partition member may be provided in the ventilation hood structure, and the space partition member may partition the space in the ventilation hood structure into a plurality of heat dissipation channels arranged in a horizontal direction. Meanwhile, the cross section of the channel inlet of the heat dissipation channel close to the air inlet is smaller than that of the channel inlet of the heat dissipation channel far away from the air inlet, and the cross section of the channel inlet of the heat dissipation channel corresponding to the air inlet is smaller than that of the air inlet.

The arrangement can split the wind direction blowing from the air inlet to the air outlet close to the right side, namely the area of the air outlet is increased, the air quantity is dispersed at the moment, the air speed can be reduced, the air flow speed around the stove flame is not too fast, and the influence on the heat efficiency of the stove is reduced.

In one possible case, if the vertical distance between the air inlet and the air outlet is sufficiently large, and the area of the air inlet is smaller than that of the air outlet, when high-speed hot air flows in from the air inlet, the hot air can be diffused in the space between the air inlet and the air outlet, flows, and is discharged from the air outlet with a larger area. In this case, the problem of the inability to discharge the hot air relatively dispersedly is also eliminated, and if a space blocking member is provided in the hood structure at this time, the drainage effect of the space blocking member is not obvious.

In summary, if the vertical distance H between the air outlet and the air inlet is smaller, the size of the air inlet is unchanged, and under the condition that the wind speed of the wind discharged from the air outlet channel of the heat dissipation fan is larger and the wind quantity is large, the wind in the heat dissipation fan cannot be discharged through the ventilation hood structure in a relatively dispersed manner. The problem can be solved by arranging a space partition in the ventilation hood structure and ensuring the relationship between the air inlet and the channel inlet cross sections of the heat dissipation channels and the arrangement of the channel inlet cross sections of each heat dissipation channel.

If the vertical distance between the air outlet and the air inlet is relatively large, under the condition that the wind speed of the wind discharged from the air outlet channel of the heat radiation fan is relatively large and the wind quantity is large, the hot air can be discharged from each air outlet of the whole ventilation hood structure in a relatively dispersed manner, and the problem that the wind in the heat radiation fan cannot be discharged through the ventilation hood structure in a relatively dispersed manner is avoided, so that a space partition piece is not required to be arranged in the ventilation hood structure.

The first preset distance mentioned above is the critical distance for discharging the hot air from each air outlet of the whole ventilation hood structure to realize the relative dispersion of the hot air. If the vertical distance between the air inlet and the air outlet is greater than the first preset distance, no space partition member is necessary at this time, and if the vertical distance between the air inlet and the air outlet is less than the first preset distance, the space partition member is arranged to help solve the problem that hot air cannot be discharged from the ventilation hood structure in a relatively dispersed manner. Therefore, the first preset distance is a precondition for providing the space-blocking member.

Optionally, the first preset distance may be determined according to a total factor such as a maximum wind speed and a maximum wind amount of hot wind blown out by the heat dissipation fan, a size of the ventilation hood structure, and a space of the equipment in which the ventilation hood structure is arranged. In an alternative embodiment, the interval range of the first preset distance may include [5cm,10cm ], or the first preset distance is [2cm,20cm ], for example, the first preset distance is 8cm, or 15cm, where cm represents a centimeter in length units.

The vertical distance H between the air outlet and the air inlet is smaller than a first preset distance, and the first preset distance is the critical distance for discharging the hot air from each air outlet of the whole ventilation hood structure in a relatively dispersed manner. If the vertical distance between the air inlet and the air outlet is greater than the first preset distance, in this case, if the space partition is not provided, the hot air can be discharged from the ventilation hood structure in a relatively dispersed manner. At this time, the space partition member is arranged to lose the effect of the split flow, so that the vertical distance between the air outlet and the air inlet is smaller than the first preset distance, and the space partition member is arranged to have the effect of the split flow of the hot air under the condition.

In an alternative embodiment, as further described in connection with fig. 3 and 4, at least one space-blocking member may be provided in the space defined by the hood structure, the space-blocking member being adapted to block the space from a plurality of heat-dissipating channels arranged in a horizontal direction. Optionally, the material of the space partition member may be aluminum alloy, stainless steel or galvanized steel sheet material, and the space partition member may be welded on the inner side of the cover plate of the ventilation hood structure and not in contact with the side wall plate, and may be connected on the inner side of the cover plate in a bonding manner to form a certain ventilation space with the side wall plate.

Fig. 6 is a simplified schematic diagram of a channel inlet section and an air inlet section of a heat dissipation channel provided in an embodiment of the present application, as shown in fig. 6, in a plurality of formed heat dissipation channels (4), a channel inlet section h1 of a heat dissipation channel close to an air inlet (11) is smaller than a channel inlet section h2 of a heat dissipation channel far away from the air inlet (11), and a channel inlet section h1 of a heat dissipation channel corresponding to the air inlet (11) is smaller than a section h3 of the air inlet (11). When the vertical distance H between the air inlet (11) and the air outlet (12) is smaller than the first preset distance, hot air in the heat dissipation fan reaches the ventilation hood structure through the air inlet, and the channel inlet section H1 of the heat dissipation channel corresponding to the air inlet is smaller than the section H3 of the air inlet.

Thus, the air quantity of the heat dissipation channel corresponding to the air inlet is smaller than the total air quantity entering the air inlet, and the hot air is dispersed and discharged from other heat dissipation channels. In order to reduce the air quantity discharged from the heat dissipation channel close to the air inlet and increase the air quantity discharged from the heat dissipation channel far away from the air inlet, the channel inlet section h1 of the heat dissipation channel close to the air inlet can be smaller than the channel inlet section h2 of the heat dissipation channel far away from the air inlet, so that the hot air in the heat dissipation fan can be discharged from the ventilation hood structure in a relatively dispersed manner.

In an alternative embodiment, further described in connection with fig. 5, when the at least one space-dividing member (2) comprises a plurality of space-dividing members, the channel inlet cross-section of each of the plurality of heat-dissipating channels (4) is related to the length of the corresponding space-dividing member of the air inlet (11), the drainage structure and the location of placement within the ventilation hood structure (1).

Specifically, the channel inlet cross section of each of the plurality of heat dissipation channels may be changed by adjusting at least one of three factors, namely, the length of the space partition member corresponding to the air inlet, the drainage structure, and the position of the space partition member in the ventilation hood structure. The hot air quantity flowing in the place with small inlet section of the heat dissipation channel is smaller, and the hot air quantity flowing in the place with large inlet section of the heat dissipation channel is relatively larger. Therefore, the total amount of the hot air entering from the air inlet can be split, so that the hot air is discharged from different heat dissipation channels, the splitting effect on the hot air is realized, and the flow speed and the flow rate of the hot air can be reduced. The discharged air velocity is reduced, the flow is relatively dispersed, the air flow speed around the flame of the kitchen range is not too high, the temperature around the kitchen range is not too high, and the thermal efficiency of the kitchen range is not greatly affected.

In an alternative embodiment, the arrangement of the plurality of space-blocking members (2) in the ventilation hood structure (1) is of a first type, the drainage structure of each space-blocking member (2) is of a first drainage structure, and the length of the space-blocking member close to the air inlet (11) is greater than the length of the space-blocking member away from the air inlet (11). Each space partition member in the first type representation space partition members (2) is located in the ventilation hood structure (1) at the same starting position of the air outlet (12), the space partition members (2) are arranged in parallel, and the drainage surface of each space partition member (2) is a plane by the first drainage structure representation.

Specifically, fig. 7 is a schematic top view diagram of a space partition member according to an embodiment of the present application, as shown in fig. 7, when the arrangement type of a plurality of space partition members (2) in a ventilation hood structure (1) is a first type, that is, each space partition member of the plurality of space partition members (2) is located in the ventilation hood structure (1) at the same starting position of an air outlet (12), and the plurality of space partition members (2) are arranged in parallel, and when the drainage surface of each space partition member (2) is planar, the length of the space partition member close to an air inlet (11) is greater than the length of the space partition member far away from the air inlet (11).

This is because the same starting position of each of the plurality of space-blocking members is set, the same drainage structure, and the size of the passage inlet cross section of the heat dissipation passage is adjusted by adjusting the length of the space-blocking member set. For example, in fig. 7, the length of the space partition member near the air inlet is greater than the length of the space partition member far away from the air inlet, when hot air flows into the air inlet, the length of the space partition member near the air inlet is longer, and when hot air flows through the position of the space partition member, the longer space partition member can block and disperse the hot air earlier, so that the hot air is split. At this time, the total air quantity entering from the air inlet is dispersed into different heat dissipation channels, so that the flow speed and the flow quantity of the air can be reduced. The discharged air velocity is reduced, the flow is relatively dispersed, the air flow speed around the flame of the kitchen range is not too high, the temperature around the kitchen range is not too high, and the thermal efficiency of the kitchen range is not greatly affected.

In an alternative embodiment, the arrangement of the plurality of space dividers (2) in the ventilation hood structure (1) is of the second type, and the drainage structure of each space divider (2) is of the first drainage structure. Each space partition member in the second type representation space partition members (2) is located in the ventilation hood structure (1) at the same starting position of the air outlet (12), the space partition members (2) are arranged radially, and the drainage surface of each space partition member (2) is a plane by the first drainage structure representation.

Specifically, fig. 8 is a schematic top view diagram of a space partition member arrangement provided in this embodiment, as shown in fig. 8, when the arrangement type of the space partition members (2) in the ventilation hood structure (1) is the second type, that is, each space partition member of the space partition members (2) is located in the same starting position of the air outlet (12) in the ventilation hood structure (1), and the space partition members (2) are arranged radially. The drainage surface of each space partition member (2) is a plane, and at this time, the length of the space partition member close to the air inlet (11) can be greater than the length of the space partition member far away from the air inlet (11), or can be equal to or less than the length of the space partition member far away from the air inlet.

This is because, in the case of radial arrangement, when each space partition member is located at the same starting position of the air outlet in the ventilation hood structure, the arrangement itself can adjust the size of the channel inlet section of each heat dissipation channel, and at this time, the influence on the size of the channel inlet section of the heat dissipation channel is not obvious by changing the length. Through setting up the position structure of radial arrangement's space partition piece, the passageway import cross-section of the position department heat dissipation passageway that is close to the air intake is less than the passageway import cross-section of keeping away from the air intake heat dissipation passageway, can guarantee like this that the total amount of wind that flows into the air intake is dispersed in a plurality of heat dissipation passageways, plays certain reposition of redundant personnel effect.

In an alternative embodiment, the arrangement of the plurality of space dividers (2) in the ventilation hood structure (1) is of a second type, and the drainage structure of the plurality of space dividers (2) is of a second drainage structure. The second type characterizes that each of the plurality of space partition pieces (2) is located at the same starting position of the air outlet (12) in the ventilation hood structure (1), and the plurality of space partition pieces (2) are arranged radially. The second drainage structure characterizes the drainage structure of the plurality of space partition pieces (2) as a curved surface drainage structure or a bevel drainage structure.

Specifically, when the arrangement type of the plurality of space partition members in the ventilation hood structure is the second type, that is, each space partition member in the plurality of space partition members is in the ventilation hood structure and is located at the same starting position of the air outlet, the plurality of space partition members are arranged radially, and the drainage structure of each space partition member can be a curved drainage structure or a folded drainage structure.

When hot air meets the space partition member through the air inlet, if the space partition member is of a folded angle drainage structure or a curved surface drainage structure, the air is blocked by the drainage surface of the space partition member, the flowing direction is changed, and the air flows along the drainage surface of the space partition member and enters different heat dissipation channels to achieve the functions of dispersing air quantity and reducing air speed. The discharged air velocity is reduced, the flow is relatively dispersed, the air flow speed around the flame of the kitchen range is not too high, the temperature around the kitchen range is not too high, and the thermal efficiency of the kitchen range is not greatly affected.

In an alternative embodiment, in the case that the lengths of the plurality of space dividers (2) are the same, the degree of bending of the curved surface of the drainage structure of the space divider close to the air inlet (11) is greater than the degree of bending of the curved surface of the drainage structure of the space divider far from the air inlet (11).

Specifically, fig. 9 is a schematic top view diagram of a space partition member arrangement provided in the embodiment of the present application, as shown in fig. 9, the arrangement type of the space partition members (2) in the ventilation hood structure (1) is a second type, that is, each space partition member in the space partition members (2) is located in the ventilation hood structure (1) at the same starting position of the air outlet (12), and the space partition members (2) are radially arranged. When the drainage structure of the plurality of space partition members (2) is a folded angle drainage structure, each of the plurality of space partition members (2) may include a first partition member (21) and a second partition member (22). The range of the folding angle (23) between the first partition piece (21) and the second partition piece (22) comprises [90 degrees, 180 degrees ], and the folding angle of the space partition piece close to the air inlet (11) is smaller than that of the space partition piece far away from the air inlet (11).

Alternatively, the connection between the first partition member and the second partition member may be welded or bonded. The first partition member and the second partition member may be connected to form a folding angle, and the folding angle may be in a range of [90 °,180 ° ], and the folding angle of the space partition member closer to the air inlet is smaller. Therefore, the size of the channel inlet section of the heat dissipation channel can be adjusted by adjusting the size of the folded angle, the channel inlet section of the heat dissipation channel close to the air inlet is ensured to be smaller than the channel inlet section of the heat dissipation channel far away from the air inlet, and the total air quantity flowing into the air inlet is dispersed into a plurality of heat dissipation channels to play a certain shunting effect.

In an alternative embodiment, fig. 10 is a schematic top view of one space partition arrangement provided in the embodiment of the present application, as shown in fig. 10, where the arrangement type of the plurality of space partitions (2) in the ventilation hood structure (1) is a second type, that is, each space partition of the plurality of space partitions (2) is located at the same starting position of the air outlet (12) in the ventilation hood structure (1), and the plurality of space partitions (2) are radially arranged. When the drainage structure of the plurality of space partition members (2) is a curved surface drainage structure, the curved surface radian of the space partition member close to the air inlet (11) in the plurality of space partition members (2) is larger than the curved surface radian of the space partition member far away from the air inlet (11).

Therefore, the size of the channel inlet section of the heat dissipation channel can be adjusted by adjusting the curved surface radian of the space partition piece, the channel inlet section of the heat dissipation channel close to the air inlet is ensured to be smaller than the channel inlet section of the heat dissipation channel far away from the air inlet, and the total air quantity flowing into the air inlet is dispersed into a plurality of heat dissipation channels to play a certain shunting effect. The discharged air velocity is reduced, the flow is relatively dispersed, the air flow speed around the flame of the kitchen range is not too high, the temperature around the kitchen range is not too high, and the thermal efficiency of the kitchen range is not greatly affected.

On the other hand, the embodiment of the application provides an integrated kitchen structure, which comprises the air duct structure.

In an alternative embodiment, fig. 11 is a schematic view of an integrated stove structure including a cooling hood structure and an air duct structure provided in the embodiment of the present application, and as shown in fig. 11, the integrated stove structure may further include a cooling hood structure (5) detachably connected to the air duct structure, where a side plate (51) is disposed on a side of the cooling hood structure (5) facing the air outlet (12). The side plate (51) comprises at least one cooling inlet (52) communicating with the air outlet (12).

Specifically, fig. 12 is a detailed schematic diagram of the inside of a cooling hood structure provided in the embodiment of the present application, and as shown in fig. 12, the cooling hood structure (5) connected to the air duct structure is included in the drawing, and the cooling hood structure (5) includes a side plate (51). At least one cooling inlet (52) can be formed in the side plate, and the cooling inlet (52) can be communicated with an air outlet (12) of the air duct structure. The cooling cover structure can be detachably connected with the air duct structure, and also can be installed on equipment (such as an integrated kitchen structure) provided with the air duct structure, and meanwhile, the cooling cover structure (5) is correspondingly arranged with an air outlet (12) of the air duct structure.

Optionally, the cooling cover structure (5) may be connected to the edge of the air duct structure by screws, or may be connected to a device equipped with the air duct structure by screws, while being in contact with the air outlet (12) of the air duct structure. A side plate (51) is arranged on one side of the cooling cover structure (5) facing the air outlet (12), and the material of the side plate (51) can be a metal material. The side plate (51) can comprise one or more cooling inlets (52), the cooling inlets (52) are used for being communicated with the air outlet (12), hot air flowing out of the air outlet enters the cooling cover structure through the cooling inlets, the cooling cover structure can cool the hot air, a large amount of heat is prevented from being accumulated in a place close to the kitchen range by the hot air, the kitchen range is enabled to be in a high-temperature environment for a long time, and then the heat effect of the kitchen range is affected.

When the number of cooling inlets on the side plate is one, a thicker side plate needs to be provided. This is because only one cooling inlet is provided, and the blown air is concentrated at the inlet, where the air volume and the air velocity are larger than those of the other parts of the side plate, a relatively concentrated pressure is generated around the cooling inlet, and the side plate is easily deformed by the pressure, so that the possibility of deformation of the side plate can be reduced by increasing the thickness of the side plate.

Alternatively, when the number of cooling inlets on the side plate is plural, the cooling inlets may be arranged relatively uniformly on the side edges, and the air in the air outlet of the air duct structure may be split again at the cooling inlets. Meanwhile, the hot air entering the cooling cover structure can be cooled, so that the blown air is relatively dispersed and the temperature is not very high, the influence of the relatively dispersed air on the air circulation speed around the flame of the kitchen range is not very great, and the temperature around the kitchen range is not too high. Therefore, the influence of the cooling treatment and the wind after the diversion on the heat efficiency of the kitchen range becomes smaller.

Through setting up a cooling cover structure of being connected with the wind channel structure can carry out a reposition of redundant personnel processing again to follow air outlet exhaust wind, can also cool down to hot-blast simultaneously. The air blown out in this way is relatively dispersed and the temperature is not very high, the circulation speed of air around the flame of the kitchen range can not be increased by the relatively dispersed air, and meanwhile, very high heat can not be accumulated around the kitchen range, so that the influence of the air exhausted from the heat radiation fan on the heat efficiency of the kitchen range can be reduced.

The application provides an air duct structure and integrated kitchen structure, this air duct structure includes ventilation hood structure and at least one space partition piece, ventilation hood structure includes air intake and air outlet, the air-out passageway of air intake and radiator fan is connected, at least one space partition piece sets up in ventilation hood structure, a plurality of heat dissipation channels that make the space partition in the ventilation hood structure parallel in the horizontal direction, in a plurality of heat dissipation channels, the passageway import cross-section of the heat dissipation channel that is close to the air intake is less than the passageway import cross-section of the heat dissipation channel that keeps away from the air intake, the passageway import cross-section of the heat dissipation channel that corresponds with the air intake is less than the cross-section of air intake.

According to the embodiment of the application, the space partition piece is arranged in the air duct structure to form the plurality of heat dissipation channels, the relative size of the channel inlet section of each heat dissipation channel and the relative size of the channel inlet section and the air inlet section of the heat dissipation channel corresponding to the air inlet are adjusted, so that hot air blown out of the heat dissipation fan can be dispersed and discharged from the plurality of heat dissipation channels, the air quantity of the hot air can be reduced because the hot air is dispersed, the air speed is reduced, the temperature around the kitchen range can not be too high, the speed of air circulation around the kitchen range flame is reduced, and further the influence of the hot air on the heat efficiency of the kitchen range is reduced.
