[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0035] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0036] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0040] like Figures 1 to 8As shown, the present invention provides an integrated range hood system, comprising: a casing 1, having a first heat exchange chamber 12 and a second heat exchange chamber 13 independent of the first heat exchange chamber 12 at the upper part, a smoke exhaust chamber 11 at the lower part of the casing 1, and a smoking port 14 at the lower side of the casing 1, the smoking port 14 is connected with the smoke exhaust chamber 11 to form an oil smoke suction channel; a heat exchange component 3, comprising an evaporator 31 arranged in the first heat exchange chamber 12 and a condenser 33 arranged in the second heat exchange chamber 13, the condenser 33 and the evaporator 31 are connected to each other to form a heat exchange flow channel for circulating refrigerant; a return air port, an air supply port 15 and an air inlet 16 are provided on the casing 1, the return air port and the air supply port 15 are both connected with the first heat exchange chamber 12, and the air inlet 16 is connected with the second heat exchange chamber 13; an external exhaust pipe 2, having a first interface and a second interface for connecting with a common flue, the outlet ends of the oil smoke suction channel and the second heat exchange chamber 13 are both connected with the first interface of the external exhaust pipe 2.

[0041] During the operation of the integrated range hood system provided in this embodiment, the oil smoke in the kitchen can enter the exhaust chamber 11 through the smoke inlet 14, then enter the external exhaust pipe 2 through the first interface, and finally be discharged to the outside through the second interface. In the first heat exchange chamber 12, the gas cooled by the evaporator 31 can enter the room through the air supply port 15 to reduce the temperature in the kitchen. In the second heat exchange chamber 13, the gas heated by the condenser 33 can enter the external exhaust pipe 2 through the first interface from the second heat exchange chamber 13, and then be discharged to the outside through the second interface. The refrigerant circulation is realized between the evaporator 31 and the condenser 33. The integrated range hood system realizes the extraction of oil smoke and also realizes the adjustment of the air temperature in the kitchen.

[0042] Therefore, the integrated range hood system provided in this embodiment integrates the functions of extracting oil fumes and regulating indoor air temperature. In summer, it can achieve oil fume extraction and cooling of the kitchen, which can improve the high-temperature cooking environment and enhance the user's cooking experience. The integrated range hood system can be installed in the kitchen to achieve oil fume extraction and temperature regulation, without the need to install a range hood and air conditioner separately in the kitchen, which simplifies the installation process and facilitates installation. Compared with independent range hoods and air conditioners, the integrated range hood system has a compact structure and occupies less space overall. The integrated range hood system has a regular structure, avoiding multiple and cluttered components in the kitchen.

[0043] In addition, in the height direction of the housing 1, the first heat exchange chamber 12 and the second heat exchange chamber 13 are located above the smoke exhaust chamber 11, which can make full use of the space above the kitchen, avoid the lower part of the device being too thick and occupying too much space near the stove or the ground in the kitchen, and facilitate people's activities. The exhaust of oil smoke from the smoke exhaust chamber 11 and the exhaust of gas from the second heat exchange chamber 13 are achieved through the same external exhaust pipe 2, that is, the exhaust of heat and smoke are integrated and discharged into the flue through the external exhaust pipe 2, which not only reduces the pipeline structure, but also the two can share the kitchen flue hole, which further facilitates installation, reduces damage to the integrity of the kitchen, and improves installation adaptability.

[0044] It is understandable that the heat exchange assembly 3 further includes a blower 32 disposed in the first heat exchange chamber 12 and an exhaust fan 34 disposed in the second heat exchange chamber 13. The blower 32 delivers the gas in the first heat exchange chamber 12 into the room, and sucks the gas outside the housing 1 into the first heat exchange chamber 12 from the return air port, so as to realize the gas circulation in the first heat exchange chamber 12, that is, the blower 32 provides power for the gas flow in the first heat exchange chamber 12. The exhaust fan 34 discharges the gas in the second heat exchange chamber 13 into the external exhaust pipe 2, and sucks the gas outside the housing 1 into the second heat exchange chamber 13 from the air inlet 16, so as to realize the gas circulation in the second heat exchange chamber 13, that is, the exhaust fan 34 provides power for the gas flow in the second heat exchange chamber 13. A fume suction fan is disposed in the smoke exhaust chamber 11, so that the fume can be sucked into the smoke exhaust chamber 11 and delivered into the external exhaust pipe 2, that is, the fume suction fan provides power for the fume flow in the fume suction channel.

[0045] The housing 1 may be a whole, and a partition is arranged in the housing 1 to separate the smoke exhaust chamber 11, the first heat exchange chamber 12 and the second heat exchange chamber 13. The housing 1 may also include an upper housing 1 and a lower housing 1 that are detachably connected, a partition is arranged in the upper housing 1 to form the first heat exchange chamber 12 and the second heat exchange chamber 13, and a smoke exhaust chamber 11 is formed in the lower housing 1, that is, the integrated range hood system includes an upper part and a lower part that are detachably connected to each other, which is convenient for transportation and installation.

[0046] On the basis of the above embodiment, further, the external exhaust pipe 2 can be arranged outside the casing 1, and the smoke exhaust chamber 11 and the second heat exchange chamber 13 are both provided with communication ports that can communicate with the external exhaust pipe 2.

[0047] As an alternative, Figure 2 and Figure 3The external exhaust pipe 2 includes a first pipe section 21, a second pipe section 22 and a third pipe section 23. The first interface includes a smoke exhaust interface connected to the smoke exhaust chamber 11 and a heat exhaust interface connected to the second heat exchange chamber 13; the first pipe section 21 is arranged in the first heat exchange chamber 12, and one end of the first pipe section 21 is opened to form a smoke exhaust interface; the second pipe section 22 is arranged in the second heat exchange chamber 13, and one end of the second pipe section 22 is opened to form a heat exhaust interface; the third pipe section 23 is arranged outside the casing 1 and is located at the top of the casing 1; the other end opening of the first pipe section 21 and the other end opening of the second pipe section 22 are both connected to one end opening of the third pipe section 23, and the other end opening of the third pipe section 23 forms a second interface.

[0048] In this embodiment, the oil smoke in the smoke exhaust chamber 11 can enter the first pipe section 21 through the smoke exhaust interface, then enter the third pipe section 23, and then be discharged to the outside through the second interface. The gas in the second heat exchange chamber 13 can enter the second pipe section 22 through the heat exhaust interface, then enter the third pipe section 23, and finally be discharged to the outside through the second interface. The first pipe section 21 is arranged in the first heat exchange chamber 12, the second pipe section 22 is arranged in the second heat exchange chamber 13, and the third pipe section 23 is arranged on the top of the casing 1, then a part of the external exhaust pipe 2 can be integrated in the casing 1, avoiding the first pipe section 21 and the second pipe section 22 being arranged outside the casing 1 to increase the thickness or width of the entire integrated range hood system, thereby making the structure of the integrated range hood system more compact.

[0049] The first pipe section 21 and the second pipe section 22 may be staggered in a front-to-rear direction of the thickness of the casing 1 .

[0050] As an alternative, Figure 2 and Figure 3 As shown, in the width direction of the casing 1, the first heat exchange chamber 12 and the second heat exchange chamber 13 are arranged side by side, and the first pipe section 21 and the second pipe section 22 are arranged side by side; the first pipe section 21 and the second pipe section 22 extend vertically.

[0051] In this embodiment, the first pipe section 21 and the second pipe section 22 are arranged side by side in the width direction of the casing 1, which is conducive to the first pipe section 21 and the second pipe section 22 being arranged flush in the thickness direction, making the structure of the integrated range hood system more compact.

[0052] Optionally, the air outlet of the exhaust fan 34 is connected to the heat exhaust interface. In this embodiment, the exhaust fan 34 is directly arranged on the second pipe 22, which is more conducive to exhaust and heat exhaust.

[0053] As an alternative, Figure 6As shown, a guide plate 24 is provided in the third pipe segment 23, and the guide plate 24 divides the inner cavity of the third pipe segment 23 into a first cavity 25 and a second cavity 26, and divides the first end opening of the third pipe segment 23 into a first sub-air inlet 27 connected to the first cavity 25 and a second sub-air inlet 28 connected to the second cavity 26, and divides the second end opening of the third pipe segment 23 into a first sub-air outlet 29 connected to the first cavity 25 and a second sub-air outlet 230 connected to the second cavity 26 (that is, the second interface includes the first sub-air outlet 29 and the second sub-air outlet 230); the first sub-air inlet 27 is connected to the first pipe segment 21, and the second sub-air inlet 28 is connected to the second pipe segment 22.

[0054] In this embodiment, in the third pipe section 23, the first sub-air inlet 27, the first cavity 25 and the first sub-air outlet 29 form a first flow channel, and the second sub-air inlet 28, the second cavity 26 and the second sub-air outlet 230 form a second flow channel. The oil smoke in the first pipe section 21 can be discharged to the outside through the first flow channel to achieve smoke exhaust. The gas in the second heat exchange cavity 13 can be discharged to the outside through the second flow channel to achieve heat exhaust. The public kitchen flue usually has static pressure. When the power of the oil fume suction fan is large and the power of the exhaust fan is small, if it is convenient for the exhaust gas in the second area to be discharged smoothly, the oil fume suction fan is required to first discharge the oil fume to the public kitchen flue so that the oil fume airflow breaks the original flow state of the public kitchen flue to offset or reduce the static pressure. In the third pipe section of the present embodiment, a guide plate is arranged in order to form a mutually independent smoke exhaust flow channel and a heat exhaust flow channel, so that the oil smoke and gas can be discharged independently from each other, which can realize that the smoke exhaust flow channel breaks the static pressure of the public kitchen flue, provides space for the exhaust gas to be discharged, and avoids the mixing of oil smoke and gas when the smoke and heat are exhausted through one flow channel, which hinders the smoke exhaust flow channel from breaking the static pressure of the public kitchen flue, and realizes that the heat exhaust is carried out normally without increasing the power of the exhaust fan, reducing the production cost and reducing the noise. Moreover, the guide plate is arranged to form two mutually independent smoke exhaust flow channels and heat exhaust flow channels, so that the power loss in the flow channels of the oil smoke fan and the exhaust fan can be avoided, and the impact effect can be ensured. The oil smoke and hot gas can be discharged independently from each other without interfering with each other, so that both the smoke exhaust effect and the heat exhaust effect can be guaranteed, and the same effect can be achieved by increasing energy consumption. The problem of poor effect or high energy consumption when smoke and heat exhaust are carried out simultaneously is solved with a simple and easy-to-process structure, and the production cost is low and the use cost is low.

[0055] Specifically, Figure 6As shown, the opening direction of the first end opening of the third pipe 23 and the opening direction of the second end opening of the third pipe 23 are arranged to intersect, the first branch air inlet 27 and the second branch air inlet 28 are arranged side by side along the width direction of the casing 1, and the first branch air outlet 29 and the second branch air outlet 230 are arranged side by side along the height direction of the casing 1. In this embodiment, the third pipe section 23 is bent to facilitate connection with the kitchen flue hole on the wall.

[0056] Preferably, the bend of the third pipe section 23 is smoothly transitioned, so that the gas flow is smoother. The pipe part of the third pipe section 23 can be set in a rectangular shape, and the second end opening of the third pipe section 23 can be circular, which is convenient for connection with the kitchen flue hole. The size of the second end opening of the circular third pipe section 23 can be 150mm, 160mm, 180mm, 200mm, etc. The arrangement position of the guide plate 24, the size of the guide arc R, etc. can be determined by the flow rate of oil smoke and air conditioning exhaust hot air, and the partition guide plate 24 adapted to the configuration of different range hoods and refrigeration modules can be allocated.

[0057] The cross-sectional area of ​​the first cavity 25 and the cross-sectional area of ​​the second cavity 26 may be equal or unequal, and may be set in a certain ratio. Of course, the cross-sectional area of ​​the first cavity 25 may be equal everywhere, or may be gradually expanded or gradually reduced from the first sub-air inlet 27 to the first sub-air outlet 29; the cross-sectional area of ​​the second cavity 26 may be equal everywhere, or may be gradually expanded or gradually reduced from the second sub-air inlet 28 to the second sub-air outlet 230.

[0058] The cross-sections of the first pipe section 21 and the second pipe section 22 may both be rectangular in shape for easy processing.

[0059] like Figures 1 to 3 , Figure 7 As shown, based on any of the above embodiments, further, the casing 1 is provided with a fresh air pipe 5 connected to the first heat exchange chamber 12, and in the width direction of the casing 1, the fresh air pipe 5 and the air inlet 16 are respectively arranged on both sides of the third pipe section 23; the air supply fan 32 can also suck outdoor air into the first heat exchange chamber 12 through the fresh air pipe 5.

[0060] In this embodiment, fresh air from outdoor can be delivered into the room through the air supply fan 32 and the fresh air pipe 5, so as to adjust the indoor air environment and improve the indoor air quality. The integrated range hood system integrates the fresh air function and is more practical.

[0061] like Figure 7As shown, on the basis of the above embodiment, further, the integrated range hood system also includes: a first heat exchange side filter assembly 7, including a filter shell 71 and a filter element 72 (which can be a filter net, filter cotton, etc.); a filter cavity is provided in the filter shell 71, and the filter element 72 is arranged in the filter cavity; in the thickness direction of the filter shell 71, the two sides of the filter shell 71 respectively have an inlet and an outlet; the fresh air pipe 5 is fixed on the filter shell 71, and the fresh air pipe 5 is connected to the filter cavity; the filter shell 71 is arranged in the return air outlet (for example, the filter shell 81 is embedded in the return air outlet).

[0062] In this embodiment, a first heat exchange side filter assembly 7 is provided at the return air inlet. When the heat exchange assembly 3 is working, that is, when the temperature adjustment function is turned on, the indoor gas enters the first heat exchange chamber 12 through the inlet first and then enters the filter chamber through the outlet after being filtered, thereby ensuring the cleanliness of the gas entering the first heat exchange chamber 12. When the fresh air function is turned on, the outdoor gas enters the filter chamber through the fresh air pipe 5, and the filtered fresh air gas enters the first heat exchange chamber 12 through the outlet, thereby ensuring the cleanliness of the fresh air. The fresh air pipe 5 is integrated on the first heat exchange side filter assembly 7, and the return air and the fresh air share a filter structure, further making the integrated range hood system highly integrated and compact in structure.

[0063] It is understandable that a second heat exchange filtering assembly (for example, including a mounting frame and a filter screen, filter cotton, etc. fixed on the mounting frame) may be further provided at the air inlet 16 to filter the gas entering the second heat exchange chamber 13 .

[0064] like Figure 2 As shown, based on the above embodiment, the integrated range hood system further includes: a heating element 6, which is arranged in the first heat exchange chamber 12.

[0065] In this embodiment, a heating element 6 (for example, an electric heating wire, an electric heating plate or a PTC heating element 6, etc.) is arranged in the first heat exchange chamber 12, so that the gas in the first heat exchange chamber 12 can be heated in winter, so that when the fresh air function is enabled, the low-temperature gas entering from the outside can be heated, thereby avoiding the low temperature of the fresh air entering the room and avoiding affecting people's cooking experience.

[0066] As an alternative, Figure 1 and Figure 2 As shown, based on the above embodiment, further, in the width direction of the casing 1, the first heat exchange chamber 12 and the second heat exchange chamber 13 are arranged side by side; in the height direction of the casing 1, the return air port and the air inlet 16 are both arranged at the top of the casing 1. In this way, the height direction of the integrated range hood system can be utilized to reduce its thickness direction dimension.

[0067] like Figure 8As shown, based on the above embodiment, the evaporator 31 further includes: a heat exchange pipe 311, a plurality of heat exchange pipes 311 are connected in sequence through a plurality of baffle pipes 312; a plurality of heat exchange pipes 311 are fixed by an end plate 313; an input pipe 314 is connected to one of the plurality of heat exchange pipes 311; a diversion pipe 315 is connected between two baffle pipes 312; and a converging pipe 316 is connected between the other two baffle pipes 412.

[0068] In this embodiment, the refrigerant can enter a heat exchange pipe 311 through an input pipe 314, and the heat exchange pipe 311 enters the corresponding baffle pipe 312, and so on, until the refrigerant enters the diversion pipe 315, and the diversion pipe 315 diverts the refrigerant to at least two baffle pipes 312, thereby diverting the refrigerant into at least two paths. The diverted refrigerant can ensure a large temperature difference with the gas, so that the refrigerant can exchange heat faster and improve the heat exchange efficiency.

[0069] If the shunt pipe 315 is connected between two baffle pipes 312, and the converging pipe 316 is connected between the other two baffle pipes 312, the refrigerant is shunted into two paths. If the shunt pipe 315 is connected between three baffle pipes 312, and the converging pipe 316 is connected between the other three baffle pipes 312, the refrigerant is shunted into three paths. Similarly, the shunt pipe 315 is connected between more baffle pipes 312 to shun the refrigerant into more paths.

[0070] like Figures 1 to 3 As shown, on the basis of the above embodiment, the integrated range hood system further includes a condensate recovery module 8, which includes: a first water receiving tray 81, which is arranged in the first heat exchange chamber 12 to collect condensate generated by the evaporator 31; along the thickness direction of the casing 1, the first pipe section 21 and the evaporator 31 are arranged side by side, and the first water receiving tray 81 is L-shaped to surround both sides of the first pipe section 21, so that the structure in the first heat exchange chamber 12 is compact; a spray member 82, which is arranged in the second heat exchange chamber 13; the spray member 82 is connected to the first water receiving tray 81 through a connecting pipe 83 to spray the condenser 33; along the width direction of the casing 1, the condenser 33 and the second pipe section 22 are respectively located on both sides of the second heat exchange chamber 13, and the spray member 82 is arranged on the side of the condenser 33 facing away from the second pipe 22; a power pump 84, which is connected to the connecting pipe 83 to pump the condensate to the spray member 82.

[0071] In this embodiment, the evaporator 31 will produce condensed water during operation, and the condensed water can drip onto the first water receiving tray 81. The power pump 84 can transport the condensed water on the first water receiving tray 81 to the spray component 82, and the spray component 82 sprays the condensed water onto the condenser 33. The high temperature of the condenser 33 can evaporate the condensed water, thereby reducing the discharge of condensed water or even eliminating the discharge of condensed water.
