Description

TECHNICAL FIELD

[0001] The utility model relates to a range hood, especially to an integrated range hood. BACKGROUND

[0002] Chinese kitchens are generally small in area, and with the improvement of living standards, smoke, stove, dishwasher, steaming oven in kitchen appliances have basically become standard. However, due to space constraints, some kitchens may not have space to install a steaming oven, and some users will balance the necessity between the steaming oven and other appliances such as a disinfection cabinet and a microwave oven, and choose to install one. Therefore, in a limited space, how to place more household appliances is a difficulty. Some users choose to install an integrated stove to integrate smoke, stove, and steaming in one countertop. Although the integrated stove integrates smoke, stove, and steaming in one countertop, it releases the space of the hanging cabinet, but due to the generally high space of the hanging cabinet, it is very inconvenient to use and has low utilization rate. Some users may choose a table type steaming oven to place the appliance on the countertop. The table type steaming oven is small in volume and low in price, and its performance is not as good as that of an embedded steaming oven. In addition, a table type hot water kettle and a rice cooker are standard in all families. If a table type steaming oven is added, the countertop will be crowded and not aesthetically pleasing. Some users choose to place an embedded steaming oven below the countertop. On the one hand, it occupies the space of the lower cabinet, and on the other hand, the user experience is very poor. The user has to bend down to place the steaming tray and clean the inner tank, and when the door is opened, the user's face will be splashed with steam. Therefore, some embedded steaming ovens are placed in high cabinets, and small kitchens do not have high cabinet space.

[0003] In addition, people have invented a lifting type range hood, i.e. the smoke inlet can be lifted. When the machine is started, the smoke inlet is lowered, and when the machine is turned off, the smoke inlet is raised. For example, the oil smoke machine disclosed in the Chinese utility model patent with the patent number 202222918682.7 (the authorized announcement number is CN 218864291 U) includes a smoke collecting cavity, a fan assembly, and a lifting assembly. The fan assembly is arranged inside the smoke collecting cavity, the lifting assembly is connected with the smoke collecting cavity, and the lifting assembly can drive the smoke collecting cavity to lift. When the oil smoke machine is running, the lifting assembly drives the smoke collecting cavity to descend below the cabinet, the fan assembly starts to suck and exhaust the oil smoke, and when the oil smoke machine is not running, the lifting assembly drives the smoke collecting cavity to rise into the cabinet, and the fan assembly is turned off. The existing lifting type range hood does not provide an integrated scheme of a cooking module. If the cooking module is integrated on the lifting type range hood, the air inlet channel needs to be designed accordingly. On the one hand, it cannot affect the lifting action, and on the other hand, it needs to ensure the oil smoke suction effect in the lowered state. UTILITY MODEL CONTENTS

[0004] The utility model solves the technical problem in the prior art, and provides an integrated range hood with a cooking module and an air inlet channel that are integrated in a lower box body and can lift synchronously.

[0005] The utility model discloses a kind of integrated range hood, including upper box and lower box, it is characterized by: cooking module is integrated on the lower box, air inlet passage is equipped between the rear side wall of the cooking module and the backplate of lower box, the lower box is driven by drive mechanism and is lifted relative to upper box, the cooking module and air inlet passage are lifted synchronously with the lifting of lower box.

[0006] Preferably, at least one channel in the air inlet passage is fixedly connected with the cooking module. In this way, the range hood can realize high-load lifting and meet the space requirements of the air inlet passage.

[0007] Further preferably, the drive mechanism is arranged in front of the air inlet passage and above the cooking module. In this way, the lifting mechanism is arranged in front of the air duct, which can save air duct space and be more conducive to oil fume extraction. In addition, the front and rear positions of the drive mechanism relative to the center of gravity of the cooking module are reasonably arranged, which can effectively avoid the problem of forward tilting of the whole machine.

[0008] The drive mechanism can be installed at multiple different positions. Preferably, a fan frame is installed inside the upper box, an oil fume fan is installed inside the fan frame, an installation cavity isolated from the air inlet passage is formed between the top of the lower box and the bottom of the fan frame, and the drive mechanism is installed in the installation cavity. In this way, the drive mechanism can be protected from oil fume pollution.

[0009] To form a sealing oil guide structure between the upper and lower boxes during lifting, an oil guide plate is installed at the bottom of the fan frame, a connecting plate is installed at the front edge of the outlet of the air inlet passage, the oil guide plate and the connecting plate are connected by a folding plate, the folding plate constitutes the rear side wall of the installation cavity, and the oil guide plate constitutes the top wall of the installation cavity. In this way, the folding plate unfolds as the lower box descends and folds as the lower box rises, and the oil in the lower box can flow into the air inlet passage through the oil guide plate and the folding plate.

[0010] To maintain fluid communication between the air inlet passage and the air inlet of the oil fume fan, left and right side plates are fixed to the top of the lower box, a back side plate is fixed above the backplate of the lower box, in the raised state of the lower box, the bottom of the fan frame is located in the area surrounded by the left and right side plates and the back side plate, in the lowered state of the lower box, the left and right side plates and the back side plate move to the lower side of the fan frame and form a flow guide passage with the unfolded folding plate, and the air inlet passage is in fluid communication with the air inlet of the oil fume fan through the flow guide passage.

[0011] To make the lower housing move more smoothly, the left side upright plate, right side upright plate and back side upright plate move up and down relative to the fan frame through a guide mechanism.

[0012] To ensure that the airflow guiding channel not only guides the airflow but also buffers it, the front-to-back width of the air inlet channel is greater than that of the inlet channel. This design buffers the airflow, thus reducing noise.

[0013] To effectively improve the fume extraction effect, preferably, the fume extraction fan has a rear air inlet, the vertical projection of which falls within the guide channel. With this configuration, the air inlet channel, guide channel, and rear air inlet form a straight exhaust channel. After the fumes are drawn in from the fume inlet of the lower housing, they can flow vertically downwards along the air inlet channel and guide channel into the rear air inlet, thus improving the fume extraction effect.

[0014] Further preferably, the folding plate includes an upper folding plate and a lower folding plate. The upper folding plate is arranged obliquely forward from top to bottom, and the lower folding plate is arranged obliquely backward from top to bottom. Since there is a negative pressure on the rear side of the folding plate after it is unfolded when the smoke machine is working, the opening direction of the folding plate faces the negative pressure side, which can make the structure more stable in the unfolded state.

[0015] The drive mechanism can have various structures. Preferably, the drive mechanism is an electric push rod, and the drive output end of the electric push rod is vertically downward and fixed to the top of the cooking module.

[0016] In order to allow the fumes to enter the air intake channel smoothly, the lower box has a fume inlet that is fluidly connected to the air intake channel.

[0017] Compared with the prior art, the advantages of this utility model are as follows: the lower box of the integrated range hood integrates a cooking module, and an air inlet channel is provided between the rear side wall of the cooking module and the back panel of the lower box. The cooking module and the air inlet channel can rise and fall synchronously with the lower box. When the lower box is lowered, the air duct is lengthened. At this time, the smoke inlet of the lower box is closer to the smoke source. The lengthened air duct can play a role in buffering the oil fumes, which is conducive to the close-range smoke extraction effect. When the lower box is raised, the whole machine has a compact structure and does not infringe on the user's cooking space. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 9 As shown, the integrated range hood of this embodiment includes an upper housing 1 and a lower housing 2. A cooking module 5 is integrated on the lower housing 2. An air inlet channel 6 is provided between the rear side wall of the cooking module 5 and the back panel of the lower housing 2. The lower housing 2 has a smoke inlet 21 that is fluidly connected to the air inlet channel 6. Driven by a drive mechanism 7, the lower housing 2 moves up and down relative to the upper housing 1. The cooking module 5 and the air inlet channel 6 move up and down synchronously with the lower housing 2. Furthermore, at least one section of the air inlet channel 6 is fixedly connected to the cooking module 5.

[0029] The upper housing 1 houses a fan frame 3, which in turn houses a range hood 4. A mounting cavity 8, isolated from the air inlet duct 6, is formed between the top of the lower housing 2 and the bottom of the fan frame 3. The mounting cavity 8 is located in front of the air inlet duct 6, and the drive mechanism 7 is installed within it, preventing oil fumes from contaminating the drive mechanism 7. Therefore, positioning the drive mechanism 7 in front of the air inlet duct 6 and above the cooking module 5 saves duct space and improves fume extraction. Furthermore, the strategically placed position of the drive mechanism 7 relative to the center of gravity of the cooking module effectively prevents the entire unit from tilting forward. In this embodiment, the drive mechanism 7 is an electric push rod, with its drive output end pointing vertically downwards and fixed to the top of the cooking module 5. In addition to housing the drive mechanism 7, the mounting cavity 8 can also be used to install a cooking light, maximizing space utilization.

[0030] like Figure 3 and Figure 7 As shown, an oil guide plate 9 is installed at the bottom of the fan frame 3, and a connecting plate 10 is installed at the front edge of the outlet of the air inlet channel 6. The oil guide plate 9 and the connecting plate 10 are connected by a folding plate 11. The folding plate 11 forms the rear side wall of the mounting cavity 8, and the oil guide plate 9 forms the top wall of the mounting cavity 8. The folding plate 11 includes an upper folding plate 111 and a lower folding plate 112. The upper folding plate 111 is arranged obliquely forward from top to bottom, and the lower folding plate 112 is arranged obliquely backward from top to bottom. That is, the opening direction of the upper folding plate 111 and the lower folding plate 112 faces the negative pressure side. The folding plate 11 is in the unfolded state. The included angle between the upper folding plate 111 and the lower folding plate 112 is preferably 140° to 150°. Using the above-mentioned included angle range can avoid the negative pressure from sucking the folding plate 11 inward and causing certain vibration and noise. In addition, the upper folding plate 111 and the lower folding plate 112 are integrally formed flexible parts. The upper folding plate 111 and the lower folding plate 112 can be embedded with sheet metal parts to ensure that the flipping structure has a certain rigidity, thereby ensuring the stability of the parts during the movement. In addition to embedding sheet metal parts, this can also be achieved by adjusting the thickness of the rubber parts.

[0031] In this embodiment, a left side upright plate 12 and a right side upright plate 13 are fixed to the top of the lower housing 2, and a back side upright plate 14 is fixed above the back panel of the lower housing 2. When the lower housing 2 is raised, the bottom of the fan frame 3 is located within the area enclosed by the left side upright plate 12, the right side upright plate 13, and the back side upright plate 14. When the lower housing 2 is lowered, the left side upright plate 12, the right side upright plate 13, and the back side upright plate 14 move to below the fan frame 3 and form a guide channel 15 with the unfolded folding plate 11. The air inlet channel 6 is in fluid communication with the air inlet of the fume extractor 4 through this guide channel 15. In this embodiment, the front-to-back width of the guide channel 15 is greater than the front-to-back width of the air inlet channel 6. Therefore, in addition to guiding the airflow, the guide channel 15 can also buffer the oil fume airflow, which helps to reduce noise. In addition, in order to make the lower housing 2 rise and fall more smoothly, in this embodiment, the left side upright plate 12, the right side upright plate 13 and the back side upright plate 14 move up and down relative to the fan frame 3 through the guide mechanism 16, which is usually a guide rail.

[0032] When the lower housing is in its lowered state, the range hood operates by drawing in fumes from the lower housing 2, which then pass through the air inlet duct 6 and the guide channel 15 before entering the air inlet of the range hood 4. In this embodiment, the range hood 4 is a centrifugal fan with dual front and rear air inlets, where the rear air inlet 41 is the main air inlet and the front air inlet 42 is the auxiliary air inlet. The rear air inlet 41 is located above the air inlet duct 6 and the guide channel 15, and its vertical projection falls within the guide channel 15. The air inlet duct 6, the guide channel 15, and the rear air inlet 41 form a straight exhaust channel. Most of the fumes entering the air inlet duct 6 flow directly upwards into the rear air inlet 41, while a small portion is guided by the oil guide plate 9 before entering the front air inlet 42.

[0033] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0034] The term "fluid connectivity" as used in this utility model refers to the spatial relationship between two components or parts, collectively referred to as the first part and the second part, meaning that a fluid, gas, liquid, or a mixture of both can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. This third party can be a fluid channel such as a pipe, channel, conduit, flow guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.
