Description

Technical Field

[0001] This utility model relates to a range hood, and more particularly to an integrated range hood. Background Technology

[0002] Range hoods have become an indispensable kitchen appliance in modern homes. Currently, range hoods are single-function products primarily used to remove cooking fumes. Cooking appliances, such as microwave ovens and steam ovens, are another type of kitchen appliance mainly used for heating, baking, and steaming food. Small kitchens have limited space and cannot accommodate multiple cooking appliances and range hoods simultaneously.

[0003] Cooking range hoods are generally categorized into top-mounted and side-mounted types. Top-mounted range hoods are increasingly widely used due to their neat, lightweight design and small footprint. However, top-mounted range hoods often have a lot of unused space, which can be wasted if not fully utilized. Therefore, solutions have been developed to utilize the unused space of the range hood for cooking equipment. Existing integrated range hoods are essentially two types combined, with the addition of the desired integrated product to the existing range hood design. For example, Chinese Patent Application No. 201620588039.4 discloses a range hood with a smoke extraction space and unused space surrounding it. The smoke extraction component is located within the smoke extraction space, while the cooking equipment is located within the unused space. The smoke extraction space can be connected to or separate from the unused space.

[0004] Existing integrated range hoods have deeply customized structures and limited integrated functions. A single platform model can only integrate one type of product, such as a steam oven. If another product is integrated, such as a disinfection cabinet, the structural platform must be redesigned. In this case, to ensure the range hood's normal smoke extraction path while avoiding an intrusive feel for the user or the need for a cabinet, it cannot be positioned too far forward. The consequence is that the space for the integrated product is too small, affecting usability. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an integrated range hood that can increase the volume of the integrated cooking module, in view of the above-mentioned existing technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an integrated range hood, including an upper box and a lower box, wherein the upper box has a fan frame inside, and a range hood fan is installed inside the fan frame. The feature is that a cooking module is integrated on the lower box. The cooking module can extend forward out of the lower box or retract backward into the lower box under the drive of the driving mechanism. Furthermore, when the cooking module extends forward out of the lower box, an air inlet channel is formed between the rear side wall of the cooking module and the back plate of the lower box. The air inlet channel is connected to the air inlet of the range hood fan.

[0007] Preferably, the fume extractor is a vertically arranged centrifugal fan, the central axis of the impeller of the fume extractor is perpendicular to the front plate of the upper housing, the fume extractor has a rear air inlet, and the air inlet channel is connected to the rear air inlet.

[0008] In a further preferred embodiment, the fume extractor also has a front air inlet, a rear air inlet as the main air inlet, and a front air inlet as an auxiliary air inlet. Both the rear air inlet and the front air inlet are connected to the air intake channel.

[0009] To improve the fume extraction effect, a main air inlet channel is formed between the rear air inlet and the back panel of the fan frame. The main air inlet channel is located directly above the air intake channel, and its front-to-back width is greater than that of the air intake channel. This arrangement creates a straight exhaust channel between the air intake channel and the main air inlet channel, resulting in better fume extraction and lower noise.

[0010] In order to make full use of the internal storage space of the lower box, the rear side wall of the cooking module is close to the back panel of the lower box when the cooking module is retracted into the lower box.

[0011] The drive mechanism can be installed in multiple different locations. Preferably, a mounting compartment is formed between the bottom of the lower housing and the top of the cooking module, the mounting compartment being isolated from the air inlet channel, and the drive mechanism is installed within the mounting compartment. This configuration avoids interference from oil fumes, thus extending the service life of the drive mechanism.

[0012] The drive mechanism can adopt various structures. Preferably, the drive mechanism is an electric telescopic rod installed on the lower housing, and the drive output end of the electric telescopic rod is installed on the cooking module.

[0013] To facilitate smoother movement of the cooking module, a guide structure is formed between the bottom of the lower housing and the top of the cooking module.

[0014] To enable the lower compartment to move up and down relative to the upper compartment, a lifting drive mechanism is installed on the upper compartment. Driven by this mechanism, the lower compartment moves up and down relative to the upper compartment. This configuration allows the cooking module to rise and fall synchronously with the lower compartment, facilitating user operation.

[0015] The lifting drive mechanism can be installed in multiple different positions. Preferably, the lifting drive mechanism is located in front of the air inlet channel and above the cooking module, and is installed in a mounting cavity isolated from the air inlet channel.

[0016] Compared with the prior art, the advantages of this utility model are as follows: the integrated cooking module of the integrated range hood can move back and forth relative to the lower box under the drive mechanism. When it extends forward into the lower box, an air intake channel is formed between the rear side wall of the cooking module and the back plate of the lower box, which does not affect the smoke extraction effect. When it retracts inward into the lower box, the space of the air intake channel can be fully utilized, thereby increasing the cooking cavity depth of the cooking module and greatly increasing the space of the cooking module. This ensures that the range hood does not increase in size due to the integration of the cooking module, and the cabinet function can be achieved at the same time. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 5 As shown, the integrated range hood of this embodiment includes an upper housing 1 and a lower housing 2. The upper housing 1 has a fan frame 3 inside, and a range hood 4 is installed inside the fan frame 3. A cooking module 5 is integrated on the lower housing 2. Driven by a drive mechanism, the cooking module 5 can extend forward from the lower housing 2 or retract backward into the lower housing 2. When the cooking module 5 is extended forward from the lower housing 2, an air inlet channel 6 is formed between the rear side wall of the cooking module 5 and the back panel of the lower housing 2, and the air inlet channel 6 is connected to the air inlet of the range hood 4. When the cooking module 5 is retracted backward into the lower housing 2, the rear side wall of the cooking module 5 abuts against the back panel of the lower housing 2.

[0024] A mounting interlayer 8 is formed between the bottom of the lower housing 2 and the top of the cooking module 5. The mounting interlayer 8 is isolated from the air inlet channel 6, and the drive mechanism is installed inside the mounting interlayer 8. In this embodiment, the drive mechanism is an electric telescopic rod 9 mounted on the lower housing 2. The drive output end of the electric telescopic rod 9 is mounted on the cooking module 5. Driven by the electric telescopic rod 9, the cooking module 5 moves back and forth relative to the lower housing 2. To make the movement of the cooking module 5 smoother, a guide structure is formed between the bottom of the lower housing 2 and the top of the cooking module 5. The guide structure can be a guide rail or a groove.

[0025] In this embodiment, the fume extractor 4 is a vertically arranged centrifugal fan, with the impeller's central axis perpendicular to the front panel of the upper housing 1. The fume extractor 4 has a rear air inlet 41 and a front air inlet 42. The rear air inlet 41 is the main air inlet, and the front air inlet 42 is an auxiliary air inlet. The air intake channel 6 is connected to both the rear air inlet 41 and the front air inlet 42. A main air intake channel 7 is formed between the rear air inlet 41 and the back panel of the fan frame 3. The main air intake channel 7 is located directly above the air intake channel 6, and its front-to-back width is greater than that of the air intake channel 6. Therefore, the main air intake channel 7 and the air intake channel 6 form a straight exhaust channel. After entering the air intake channel 6, the fumes can directly enter the main air intake channel 7 vertically upwards, improving the fume extraction effect and reducing noise.

[0026] In this embodiment, a lifting drive mechanism 10 is installed on the upper housing 1, and the lower housing 2 moves up and down relative to the upper housing 1 under the drive of the lifting drive mechanism 10. The lifting drive mechanism 10 is located in front of the air inlet channel 6 and above the cooking module 5. To avoid oil fume contamination of the lifting drive mechanism, the lifting drive mechanism 10 is installed in the mounting cavity 11, which is isolated from the air inlet channel 6.
