[0045] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] like Figures 1 to 2 As shown, this application provides an island-style integrated appliance that can be used in open kitchens and can be installed in the island cabinets of an open kitchen (not shown in the figure), which can enhance the user's cooking and dining experience.

[0047] In some embodiments, the island-style integrated unit is installed with the island cabinet as follows: the island cabinet includes a cabinet body and a countertop installed on the cabinet body. A slot is provided on the countertop that communicates with the internal space of the cabinet body. The island-style integrated unit is embedded into the internal space of the cabinet body through the slot, and part of the structure of the island-style integrated unit overlaps the countertop to realize the installation of the island-style integrated unit.

[0048] For ease of description, Figure 1 and Figure 2 The location of the all-in-one central island unit is for reference. Figure 1 and Figure 2 The "up" and "down" in the text refer to the vertical position of the island-style integrated machine. Figure 1 and Figure 2 The left and right sides of the island-style all-in-one machine are indicated by the left and right sides. Figure 1 and Figure 2 The front and rear sides in the text refer to the front and rear sides of the island-style integrated unit. It should be noted that this directional definition is mainly for the convenience of describing the technical solution of this application and should not be regarded as a limitation on the technical solution of this application.

[0049] Continue as Figures 1 to 2 As shown, the island-style integrated appliance includes an integrated casing 100, a range hood 200, an induction cooker 300, and a central control system 400. The integrated casing 100 is embedded into the cabinet from the slot, and the integrated casing 100 has an upward-facing receiving cavity 101. The range hood 200, the induction cooker 300, and the central control system 400 are all installed in the receiving cavity 101. The central control system 400 is communicatively connected to the range hood 200 and the induction cooker 300, and is used to control the range hood 200 to execute the corresponding working mode according to the operating status of the induction cooker 300.

[0050] The range hood 200 is roughly L-shaped and positioned near the left side of the receiving cavity 101, occupying the left and right bottom sides of the cavity. The induction cooker 300 is roughly cuboid in shape, mounted on the top right side of the receiving cavity 101 and above the bottom right side of the range hood 200. The central control system 400 is roughly cuboid in shape, mounted on the rear side of the bottom right side of the range hood 200 and below the induction cooker 300. This arrangement allows the range hood 200, induction cooker 300, and central control system 400 to be efficiently and rationally arranged within the receiving cavity 101. This not only improves the space utilization of the cavity 101, making the island-style integrated appliance more compact and smaller in size, adaptable to more island cabinet sizes, but also facilitates the electrical connection between the central control system 400 and the range hood 200 and induction cooker 300.

[0051] The induction cooker 300 includes an induction cooker housing 301, a heating device 303, a cooktop panel 304, and an induction cooker main control component 302. The induction cooker housing 301 is installed inside the receiving cavity 101. The heating device 303 is installed inside the induction cooker housing 301 and is used to heat the cooktop panel 304. The induction cooker main control component 302 is installed inside the induction cooker housing 301 and is located below the heating device 303. It is used to control the start and stop of the induction cooker 300 and the working mode of the induction cooker 300. The cooktop panel 304 is fixed to the top of the integrated housing 100 and covers a portion of the opening of the receiving cavity 101. The cooktop panel 304 is configured to overlap the table surface from the slot.

[0052] In addition, the main control component 302 of the induction cooker is connected to the central control system 400, which allows the central control system 400 to obtain the working status of the induction cooker 300 in a timely manner and control the range hood 200 to adjust to a suitable working state for better extraction of cooking fumes.

[0053] The induction cooker 300 also includes a cooling fan 305, which is installed on the induction cooker housing 301 and is used to dissipate heat from the main control component 302 of the induction cooker, ensuring that the main control component 302 of the induction cooker can operate stably. In order to ensure that the cooling fan 305 can draw and deliver air normally, an air intake channel 3013 is formed between the bottom of the induction cooker housing 301 and the top of the air guide cavity 4. The bottom of the induction cooker housing 301 has a first air inlet 3011 that communicates with the air intake channel 3013, and the front side wall of the integrated machine housing 100 has a second air inlet 102 that communicates with the air intake channel 3013. Similarly, the right side wall of the induction cooker housing 301 has a first air outlet 3012, and the right side wall of the integrated machine housing 100 has a second air outlet 103 that communicates with the first air outlet 3012.

[0054] In this embodiment, the second air inlet 102 and the second air outlet 103 of the all-in-one casing 100 are both grille-shaped air inlets, that is, the second air inlet 102 is formed by a plurality of elongated holes spaced apart in the left-right direction, and the second air outlet 103 is formed by a plurality of elongated holes spaced apart in the front-back direction. This arrangement can ensure air intake and exhaust while preventing external debris from entering the all-in-one casing 100, thus ensuring the stable operation of the cooling fan 305.

[0055] like Figures 3 to 4 As shown, the smoke hood 200 includes a smoke hood housing 1, a smoke collection chamber 3, an air guide chamber 4, a worm gear fan 5, a lifting device 7, and a smoke hood main control assembly 2. The smoke hood housing 1, the air guide chamber 4, and the worm gear fan 5 constitute a fan system. The smoke hood housing 1 is installed on the left side of the receiving cavity 101, and has an air inlet chamber 1101 and an air outlet chamber 1102. The smoke collection chamber 3 is vertically and vertically installed in the air inlet chamber 1101 of the smoke hood housing 1, and the lifting device 7 is used to drive the smoke collection chamber. 3. Lifting; The main control component 2 of the range hood is installed on the top of the smoke collection chamber 3 and is connected to the main control system 400 for communication. This allows the main control system 400 to control the range hood 200 to adjust to a suitable working state according to the working state of the induction cooker 300, so as to better extract oil fumes; The air guide chamber 4 is used to connect the air outlet of the air inlet chamber 1101 of the range hood housing 1 and the air inlet of the worm gear fan 5. The air outlet of the worm gear fan 5 is connected to the air inlet of the air outlet chamber 1102 of the range hood housing 1.

[0056] The range hood 200 provided in this application, on the one hand, ensures that when the worm gear fan 5 starts, a negative pressure is generated in the smoke collection chamber 3 to draw in air and / or fumes from the external environment. Then, this part of the air and / or fumes enters the smoke collection chamber 3 and then enters the worm gear fan 5 through the air guide chamber 4, and then enters the air outlet 1102 of the range hood housing 1 from the air outlet of the worm gear fan 5, and finally is discharged from the air outlet of the air outlet 1102. On the other hand, dividing the range hood 200 into multiple assemblable independent modules not only facilitates the manufacturing and processing of the range hood 200, but also facilitates the batch assembly of different modules of the range hood 200 into the receiving cavity 101 of the integrated housing 100, improving the manufacturing, processing and assembly efficiency of the range hood 200. Moreover, different modules of the range hood 200 can be inspected or replaced individually without affecting other modules, reducing the maintenance cost of the range hood 200.

[0057] The air outlet of the air outlet chamber 1102 of the range hood housing 1 is located at the bottom of the air outlet chamber 1102, and the air outlet of the air outlet chamber 1102 is located at the top of the range hood housing 1. In addition, the air inlet of the smoke collection chamber 3 is also located at the top of the range hood 200, enabling the range hood 200 to achieve an upward suction and upward exhaust mode. The upward suction and upward exhaust mode has the following advantages: First, the upward exhaust mode can be adapted to the traditional upward suction and upward exhaust duct in the kitchen, making it easy to connect the air outlet of the range hood 200 to the kitchen exhaust duct, saving the cost and construction time of duct modification; Second, the upward exhaust mode can better follow the upward airflow characteristics, reducing the resistance of airflow turning compared to the downward exhaust mode, making the smoke exhaust smoother; Third, compared with the downward exhaust mode where the duct is blocked due to the accumulation of oil, in the upward exhaust mode, the oil will flow downward or drip under the action of gravity, resulting in less oil accumulation in the duct and a smoother smoke exhaust path.

[0058] In this embodiment, the smoke collection chamber 3 is vertically and flexibly installed within the air inlet chamber 1101. The smoke collection chamber 3 has a retracted state within the air inlet chamber 1101 and a working state protruding from the air inlet chamber 1101. If the smoke collection chamber 3 is initially in the retracted state, when the range hood 200 needs to be started, the smoke collection chamber 3 moves upward to the working state protruding from the air inlet chamber 1101, so that the air inlet of the smoke collection chamber 3 is above the integrated machine casing 100, facilitating the extraction of cooking fumes. If the smoke collection chamber 3 is initially in the working state, when the range hood 200 does not need to be started and needs to be retracted, the smoke collection chamber 3 moves downward into the air inlet chamber 1101 and is in the retracted state. At this time, the top surface of the island integrated machine is a flat surface, convenient for users to eat or place household items.

[0059] It is worth noting that in this embodiment, the lifting device 7 includes a motor, a worm gear, a worm, a lead screw, and a lead screw nut. The motor drives the worm to rotate around a horizontal axis, which in turn drives the lead screw to rotate around a vertical axis. Finally, the lead screw nut drives the smoke collection chamber 3 to rise and fall along the lead screw. In other embodiments, the lifting device 7 may also use other mechanisms with linear drive functions, such as a motor gear rack mechanism, a cylinder, an electric actuator, etc., which will not be described in detail here.

[0060] In some embodiments, the air guide cavity 4 is located above the worm gear fan 5. The bottom of the air guide cavity 4 has a first connection port that connects to the air inlet of the worm gear fan 5, and its side has a second connection port that connects to the air outlet of the air inlet cavity 1101, so that the worm gear fan 5 and the air inlet cavity 1101 can be connected through the air guide cavity 4. Then, the air outlet of the worm gear fan 5 is connected to the air inlet of the air outlet cavity 1102. This configuration ensures that when the worm gear fan 5 starts, it can draw the air out of the air inlet chamber 1101 of the range hood casing 1 through the air guide chamber 4, creating a negative pressure in the air inlet chamber 1101. This causes air and / or fumes from the external environment to flow into the air inlet chamber 1101 from the air inlet, then into the worm gear fan 5 through the air guide chamber 4, and then into the air outlet chamber 1102 of the range hood casing 1 from the air outlet of the worm gear fan 5, and finally be discharged from the air outlet of the air outlet chamber 1102.

[0061] The range hood 200 also includes an oil filter assembly, which is installed at the air inlet of the smoke collection chamber 3 and covers the air inlet of the smoke collection chamber 3. The oil filter assembly is used to separate oil stains from the fumes, preventing or reducing the entry of oil stains into the range hood 200 and ensuring that the range hood 200 can work normally. In addition, the oil filter assembly can also prevent large-sized debris from the external environment from entering the range hood 200 from the air inlet of the smoke collection chamber 3, ensuring that the range hood 200 can work normally.

[0062] To facilitate the collection of oil sludge separated by the oil mesh filter assembly, an oil guide groove is provided at the bottom of the air inlet of the smoke collection chamber 3. The bottom of the oil mesh filter assembly is inserted into the oil guide groove, and an oil outlet is provided at the bottom of the oil guide groove. When oil fumes enter the smoke collection chamber 3 from the air inlet through the oil mesh filter assembly, the oil sludge is separated from the oil fumes by the action of the oil mesh filter assembly. The oil sludge adheres to the oil mesh filter assembly and flows into the oil guide groove under the action of gravity, and finally flows out from the oil outlet of the oil guide groove, flowing downward along the inner wall of the smoke collection chamber 3.

[0063] To collect grease, the range hood 200 also includes a guide member 63 and an oil cup 62. The guide member 63 is installed at the bottom front side of the range hood housing 1. Grease flowing out of the oil outlet of the oil guide groove flows along part of the structure of the range hood housing 1 to the guide member 63. The oil cup 62 is located below the guide member 63 and is used to collect the grease flowing out of the guide member 63. In practical applications, oil-absorbing paper can also be placed in the oil cup 62 to absorb the grease, which not only makes it easy to clean the grease in the oil cup 62, but also helps to keep the oil cup 62 clean.

[0064] In practice, according to the requirements of the standard test finger in the fan installation specifications, a protective net needs to be installed at the fan outlet to prevent users' or maintenance personnel's fingers from entering the fan. However, if the protective net is directly fixed to the fan outlet, not only will mounting holes need to be drilled in the fan casing, but the overall size of the fan will also increase, requiring more installation space.

[0065] To address the aforementioned issues, this application provides a fan system that optimizes the structure of the fan system, specifically by optimizing the structure of the smoke hood housing 1. This improves the structural strength of the smoke hood housing 1 while meeting standard test requirements, and makes the overall structure of the fan system more compact, thereby reducing the requirements for installation space.

[0066] like Figures 4 to 7 As shown, the range hood housing 1 includes a housing 11 and a fan protective net 12. The housing 11 has an air inlet chamber 1101 and an air outlet chamber 1102. The fan protective net 12 has multiple ventilation openings 1210. The fan protective net 12 is erected within the air outlet chamber 1102 and spaced apart from the air inlet of the worm gear fan 5. The projection of the fan protective net 12 onto the surface where the air inlet of the worm gear fan 5 is located covers the air inlet of the worm gear fan 5 to meet the requirements of standard test parameters. Simultaneously, the fan protective net 12, erected within the air outlet chamber 1102, can serve as a supporting structure for the air outlet chamber 1102, improving the overall structural stability of the housing 11. In other words, the fan protective net 12 provided in this application not only meets the requirements of standard test parameters but also serves as a supporting structure for the range hood housing 1. This not only improves the overall structural strength and stability of the range hood housing 1 but also does not occupy extra space, making the overall structure of the fan system more compact and requiring less space.

[0067] The air outlet cavity 1102 includes a first air outlet 11021 and a second air outlet 11022. The first air outlet 11021 extends vertically, and the second air outlet 11022 extends horizontally and connects to the air outlet of the worm gear fan 5. The top of the fan protective net 12 is fixed to the top wall of the second air outlet 11022, and the bottom of the fan protective net 12 is fixed to the bottom wall of the second air outlet 11022. With this configuration, the fan protective net 12 can serve as a supporting structure for the second air outlet 11022, improving the structural stability of the second air outlet 11022.

[0068] In some embodiments, the housing 11 includes a front panel 111, a rear panel 112, an upper right panel 113, a lower right panel 114, a left bottom panel 115, and a partition 116. The front panel 111 and the rear panel 112 are arranged in parallel and spaced apart. The left bottom panel 115 is connected to the left side and bottom of the front panel 111 and the rear panel 112. The upper right panel 113 is connected to the upper right side of the front panel 111 and the rear panel 112. The lower right panel 114 is connected to the lower right side of the front panel 111 and the rear panel 112. The partition 116 includes a first partition 1161 and a second partition 1162 connected to the first partition 1161 at an obtuse angle or a right angle. The second partition 1162 is connected to the lower right panel 114. The first partition 1161 extends vertically and cooperates with the second partition 1162 to divide the internal space of the housing 11 into an air inlet chamber 1101 and an L-shaped air outlet chamber 1102.

[0069] Furthermore, the top of the fan protective net 12 is fixed to the second partition 1162, and the bottom of the fan protective net 12 is fixed to the bottom of the left base plate 115. The fan protective net 12 can serve as a support structure between the bottom of the left base plate 115 and the second partition 1162, and can in particular support the second partition 1162, improve the stability of the second partition 1162, and reduce the risk of deformation of the second partition 1162.

[0070] In addition, the partition 116 also includes an exhaust protection net 1163. The exhaust protection net 1163 is connected to the upper end of the first partition 1161 away from the second partition 1162. The exhaust protection net 1163 covers the air outlet of the exhaust cavity 1102 to prevent foreign objects from falling into the exhaust cavity 1102, avoid foreign objects from blocking the exhaust cavity 1102, and ensure that the range hood 200 can normally absorb oil fumes.

[0071] like Figure 7 Combination Figure 4 As shown, the smoke hood fan system also includes a purification component 61. The purification component 61 is removably installed in the second air outlet 11022 along the horizontal front-to-back direction. The purification component 61 abuts against the side of the fan protective net 12 away from the worm gear fan 5. The fan protective net 12 is used to limit one side of the purification component 61. This arrangement gives the fan protective net 12 more functions, making it multi-purpose. It not only meets the requirements of standard test indicators, but also serves as a support structure for the second air outlet 11022, and as a limiting support structure for the purification component 61, thereby limiting the installation stability of the purification component 61.

[0072] In addition, the purification component 61 is detachably installed on the second air outlet 11022 for easy replacement. Moreover, the purification component 61 purifies the fumes, so that the fumes drawn by the range hood 200 can be directly discharged into the room without affecting the user's cooking and dining environment. This option is available for users whose kitchens do not have exhaust ducts, improving the cooking and dining experience for this type of user and meeting their needs.

[0073] Furthermore, the range hood housing 1 also includes a limiting structure 13, which is fixed inside the second air outlet 11022 and located on the side of the purification component 61 away from the fan protective net 12. The limiting structure 13 is used to limit the other side of the purification component 61, so that the limiting structure 13, together with the fan protective net 12, limits both sides of the purification component 61, thereby further improving the installation stability of the purification component 61.

[0074] In some embodiments, the limiting structure 13 includes a first L-shaped groove plate 131 and a second L-shaped groove plate 132, which are arranged opposite to each other and fixed to the top and bottom walls of the second air outlet 11022, respectively. This arrangement provides limiting support for the upper and lower ends of the purification component 61 while reducing obstruction of airflow by the limiting structure 13, ensuring smooth airflow. In other embodiments, the limiting structure 13 can also be a hollow frame structure, achieving the same effect; this is not a limitation.

[0075] In some embodiments, the fan protection net 12 includes a net body 121 and a fixed edge 122 connected to the periphery of the net body 121. The net body 121 has ventilation openings 1210, and its surface is wavy. The fixed edge 122 is used for fixed connection to the casing 11. This configuration not only facilitates the fixed connection between the fixed edge 122 and the casing 11, but also enhances the structural strength of the fan protection net 12 using the wavy net body 121.

[0076] It is understood that the fan protection net 12 is not limited to the above structure, and can also be other forms of porous sheet metal parts, as long as it can meet the standard test requirements and can be used to improve the overall structural strength and structural stability of the smoke hood shell 1, there are no restrictions here.

[0077] This application also provides a control method for an integrated island control unit, based on the aforementioned integrated island control unit, comprising the following steps:

[0078] When the user starts the induction cooker 300, the range hood 200 starts after the induction cooker 300 starts, and the smoke collection chamber 3 moves upward to the working state;

[0079] When the induction cooker 300 is in low-speed working mode, the range hood 200 will automatically adjust to low-speed working mode.

[0080] When the induction cooker 300 is in the medium-speed working mode, the range hood 200 will automatically adjust to the medium-speed working mode.

[0081] When the induction cooker 300 is in high-level working mode, the range hood 200 will automatically adjust to high-level working mode.

[0082] Among them, the low settings of the induction cooker 300 (such as "keep warm" or "simmer") typically have a power of 200W-600W, suitable for stewing and keeping warm. The medium settings of the induction cooker 300 (such as "medium heat" or "steam") typically have a power of 800W-1500W, suitable for frying eggs and cooking porridge. The high settings of the induction cooker 300 (such as "high heat" or "stir-fry") typically have a power of 1800W-2200W, suitable for quickly stir-frying vegetables and boiling water.

[0083] The essence of the 200-speed range hood is to change the exhaust volume by adjusting the rotation speed of the worm gear fan 5. The change in the rotation speed of the worm gear fan 5 is directly reflected in the "motor input power of the worm gear fan 5". For example, when the range hood is at a low speed, the motor speed of the worm gear fan 5 is slow, and the input power is low, usually between 50W and 100W, suitable for the initial stages of cooking or scenarios with less oil smoke (such as stewing). When the range hood is at a medium speed, the motor speed and input power of the worm gear fan 5 are moderate, generally between 100W and 150W, suitable for everyday stir-frying that produces moderate oil smoke. When the range hood is at a high speed, the motor of the worm gear fan 5 runs at full power, with the highest input power, usually between 150W and 250W, used to handle scenarios with strong oil smoke such as stir-frying and deep-frying.

[0084] Obviously, the above embodiments of this application are merely examples for clear illustration and are not intended to limit the implementation of this application. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
