Description

Technical Field

[0001] This utility model relates to range hoods, 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. Therefore, range hoods with integrated cooking modules were invented. These integrated range hoods consist of an upper and lower housing, with the cooking module integrated into the lower housing. For ease of operation, the cooking module can move up and down relative to the upper housing under the drive mechanism. Because the cooking module is integrated into the range hood, it is located above and in front of the user. If the cooking module uses a conventional hinged, flip-up opening mechanism like a steam oven, opening the door creates an obstruction between the user and the cooking module, preventing the user from retrieving food. Furthermore, the inner, hot side of the door faces the user. Additionally, residual liquid on the door may drip onto the stovetop or onto the user, resulting in a poor user experience. In conclusion, further improvements are needed for existing integrated range hoods. Utility Model Content

[0003] The first technical problem to be solved by this utility model is to provide an integrated range hood in which the door of the cooking module does not obstruct the user from taking out food when the existing technology is in view of the above-mentioned status quo.

[0004] The second technical problem to be solved by this utility model is to provide an integrated range hood that can prevent liquid from dripping onto the stove or a person after the door of the cooking module is opened, in light of the above-mentioned existing technology.

[0005] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: an integrated range hood, including an upper box and a lower box, wherein a cooking module is integrated on the lower box, the cooking module having a cooking cavity and a door located on the front of the cooking cavity, characterized in that: a hinge mounting cavity is formed between the left side wall of the cooking cavity and the left side plate of the lower box, and between the right side wall of the cooking cavity and the right side plate of the lower box, a hinge mechanism is installed in the hinge mounting cavity, the hinge mechanism is hinged to the back of the door, and when the door is open, the door flips to the bottom of the cooking module and is inclined inward from top to bottom, and the inner side of the door faces the inner side of the range hood.

[0006] The technical solution adopted by this utility model to solve the second technical problem mentioned above is as follows: an oil cup is installed at the bottom of the lower box. When the door is open, the door extends forward out of the cooking module and the upper edge of the door is higher than the bottom of the cooking cavity. The vertical projection of the lower edge of the inner side of the door falls into the oil cup.

[0007] In order to guide the residual water in the cooking cavity to the oil cup through the door, a sandwich is formed between the bottom of the cooking cavity and the bottom plate of the lower box. A drain pipe is installed in the sandwich. A drain outlet is opened at the bottom of the cooking cavity and a drain outlet is opened on the front of the cooking module. The drain outlet is connected to the drain outlet through the drain pipe.

[0008] Further preferably, the drain outlet is equipped with a valve, which is open when the door is open and closed when the door is closed.

[0009] The hinge mechanism can have various installation structures. Preferably, a fixing plate is installed in the hinge mounting cavity, and the hinge mechanism is hinged between the fixing plate and the door body.

[0010] In order for the door to slide downward and flip backward when opened, the hinge mechanism includes a first link and a second link. The first link is a straight rod, the rear end of which is hinged to a first hinge point of a fixed plate, and the front end of which is hinged to a second hinge point of the door. The second hinge is a U-shaped rod, the first end of which is hinged to a third hinge point of a fixed plate, and the second end of which is hinged to a fourth hinge point of the door. The first hinge point is located above and in front of the third hinge point, and the second hinge point is located above the fourth hinge point.

[0011] As a preferred embodiment of any of the above solutions, an air intake channel is formed between the rear wall of the cooking cavity and the back panel of the lower housing.

[0012] In order to allow the fumes to be drawn into the fume extractor through the air inlet duct, a fan frame is installed inside the upper housing, and a fume extractor is installed inside the fan frame. The air inlet duct is connected to the air inlet of the fume extractor.

[0013] In order to enable the lower box to move up and down relative to the upper box, a drive mechanism is installed between the bottom of the fan frame and the top of the cooking module. The lower box moves up and down relative to the upper box under the drive of the drive mechanism.

[0014] To prevent oil fumes from contaminating the drive mechanism, and also to prevent the drive mechanism from interfering with the oil fume airflow and affecting the oil fume extraction effect, the air inlet channel and the drive mechanism are isolated by a seal.

[0015] Compared with the prior art, the advantages of this utility model are as follows: When the door of the integrated range hood is open, the door flips down to the bottom of the cooking module and is tilted inward from top to bottom. Furthermore, the inner side of the door faces the inner side of the range hood, avoiding the hot surface facing the person. When fully opened, it will not obstruct people from taking food out of the cooking cavity. The door extends forward from the cooking module, and the upper edge of the door is higher than the bottom of the cooking cavity. The vertical projection of the lower edge of the inner side of the door falls into the oil cup, allowing residual water on the door to flow smoothly into the oil cup along the inner side of the door, preventing it from dripping onto the stove or onto people.

[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. A cooking module 3 is integrated on the lower housing 2. The cooking module 3 has a cooking cavity 31 and a door 32 located on the front of the cooking cavity 31. Hinges 4 are formed between the left side wall of the cooking cavity 31 and the left side panel of the lower housing 2, and between the right side wall of the cooking cavity 31 and the right side panel of the lower housing 2. A fixing plate 9 is installed in the hinge mounting cavity 4, and a hinge mechanism 5 is located in the hinge mounting cavity 4 and hinged between the fixing plate 9 and the back of the door 32.

[0024] The hinge mechanism 5 of this embodiment includes a first connecting rod 51 and a second connecting rod 52. The first connecting rod 51 is a straight rod, with its rear end hinged to a first hinge point on the fixed plate 9 and its front end hinged to a second hinge point on the door body 32. The second hinge is a U-shaped rod, with its first end hinged to a third hinge point on the fixed plate 9 and its second end hinged to a fourth hinge point on the door body 32. The first hinge point is located above and in front of the third hinge point, and the second hinge point is located above the fourth hinge point. Using the hinge mechanism 5 described above, the door body 32 can slide downwards and flip backwards when opened.

[0025] A sandwich 7 is formed between the bottom of the cooking cavity 31 and the bottom plate of the lower housing 2. A drain pipe 8 is installed in the sandwich 7. A drain outlet 33 is opened at the bottom of the cooking cavity 31, and a drain outlet 34 is opened on the front of the cooking module 3. The drain outlet 33 is connected to the drain outlet 34 through the drain pipe 8. Furthermore, a valve is installed at the drain outlet 33. The valve is open when the door 32 is open and closed when the door 32 is closed. An oil cup 6 is installed at the bottom of the lower housing 2. When the door 32 is open, the door 32 flips down to the bottom of the cooking module 3 and is inclined inward from top to bottom. The door 32 extends forward from the cooking module 3, and the upper edge of the door 32 is higher than the bottom of the cooking cavity 31. The vertical projection of the lower edge of the inner side of the door 32 falls into the oil cup 6, and the inner side of the door 32 faces the inner side of the range hood. After cooking is finished and the door 32 is opened, the drain outlet 33 opens, allowing residual water in the cooking cavity to flow into the drain pipe 8 through the drain outlet 33, then into the drain outlet 34, and finally into the oil cup 6 along the inner side of the door 32. The water in the cooking cavity 31 and the inner side of the door 32 does not require manual cleaning. Furthermore, since the inner side of the door 32 (the high-temperature side) faces the inside of the range hood when the door 32 is open, it avoids the high-temperature side of the door facing the user, resulting in a better user experience.

[0026] like Figure 6 As shown, in this embodiment, an air inlet channel 10 is formed between the rear wall of the cooking cavity 31 and the lower housing back panel 21 of the integrated range hood. A fan frame 11 is installed inside the upper housing 1, and a range hood fan (not shown) is installed inside the fan frame 11. The air inlet channel 10 is connected to the air inlet of the range hood fan. During operation, cooking fumes enter the air inlet of the range hood fan through the air inlet channel 10 and are eventually discharged to the outside of the range hood.

[0027] Furthermore, the range hood in this embodiment is a lift-type range hood. A drive mechanism 12 is installed between the bottom of the fan frame 11 and the top of the cooking module 3. The lower housing 2 moves up and down relative to the upper housing 1 under the drive of the drive mechanism 12. When the range hood is turned on, the lower housing 2 descends, the negative pressure zone moves downward, which helps to improve the smoke extraction effect. When the range hood is turned off, the lower housing 2 rises, making the overall structure of the range hood simpler. In addition, in cooking mode, after cooking is finished, the cooking module 3 descends synchronously with the lower housing 2, making it easier for the user to take out the food. The drive mechanism 12 can adopt various structures in the prior art, which will not be described in detail here. To avoid the drive mechanism 12 being interfered with by oil fumes, the air inlet channel 10 and the drive mechanism 12 are isolated by a seal 13.

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.
