Detailed ways

The specific implementations of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other under the condition of no conflict.

In the embodiments of the present invention, unless otherwise stated, the directional words used such as "upper, lower, top, bottom" are usually for the directions shown in the drawings or for vertical, vertical or A word describing the mutual positional relationship of each component in the direction of gravity.

The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

As shown in FIG. 1 to FIG. 12 , the first exemplary embodiment of the present invention provides a top suction range hood, which includes a fume collecting hood 2 , a fume collecting board 3 and a control panel 4 .

Wherein, the fume collecting hood 2 is formed with a fume collecting cavity, and the bottom of the fume collecting cavity is formed with an oil fume inlet. The smoke collecting plate 3 can completely cover or partially cover the oil fume inlet, and when smoking, it can be turned out to the bottom and front to completely open the oil fume inlet; when smoking is stopped, the smoke collecting plate 3 can be turned upward and rearward to cover the oil fume inlet again. . In addition, the control panel 4 is hidden in the bottom front area of the smoke collecting chamber. When the range hood needs to be controlled, the control panel 4 can be turned down so that the user interface faces the user, and the user interface can be provided with buttons or touch controls. When the machine is stopped, the control panel 4 is turned up to the built-in state.

When smoking, the smoke collecting plate 3, which is turned downward and forward, can gather the cooking steam in the rear area, reduce the escape of the steam, and guide the steam to flow into the oil fume inlet, so as to avoid a large amount of high-temperature steam hitting the user and causing discomfort or burns, causing the user Ability to focus on cooking without deliberately avoiding steam. In addition, the smoke collecting plate 3 and the control panel 4 are both turned down when the range hood is in operation, so as to present a different appearance from that when the range hood is stopped. Therefore, compared with the traditional range hood, the top suction range hood of this exemplary embodiment has It has a variable and novel shape, and has a high degree of aesthetics, which meets some users' pursuit of the aesthetics of household appliances and is conducive to improving the use experience.

Specifically, the control panel 4 includes a built-in end surface 4a and an exposed end surface 4b at both ends. The built-in end surface 4a refers to the top end surface of the control panel 4 in the built-in state, and the top end surface is contained in the smoke collecting chamber. The exposed end surface 4b refers to the bottom end surface of the control panel 4 in the inner state, and the bottom end surface is exposed and visible when the user looks up at the range hood.

Because the user interface has many circuit structures, it needs to be well protected to avoid high temperature steam, external pollutants, etc. causing it to fail. Therefore, the user operation interface can be set on the inner end face 4a, and when the range hood needs to be controlled, the control panel 4 can be turned out toward the bottom and rear to ensure that the user operation interface faces forward, that is, toward the user. In this way, in the shutdown state, the user operation interface is always hidden in the smoke collecting chamber, which can avoid external pollution, and when smoking, it is equivalent to turning the smoke collecting plate 3 and the control panel 4 out in reverse, and the user operation interface is due to Facing the front, it can keep away from high-temperature steam, and the control panel 4 plays the role of blocking steam, which can better avoid the formation of high-temperature damage.

The turning-out angles of the smoke collecting board 3 and the control panel 4 can be set arbitrarily, as long as it is ensured that the user operation interface faces the user and the smoke collecting board 3 has the effect of collecting smoke after turning out. For example, when smoking, the smoke collecting plate 3 can be turned out to be perpendicular to the horizontal plane. In order to expand the interception range of the smoke collecting plate 3, the maximum turning out angle of the smoke collecting plate 3 can be set to not less than 90°.

The front and rear distance between the control panel 4 and the smoke collecting board 3 should not be too large, otherwise it will affect the compactness of the hood structure and increase the volume of the whole machine. The panel 4 will limit the maximum turning out angle of the smoke collecting board 3, which will affect the smoke collecting effect. Therefore, in order to take into account the compactness of the structure and the effect of collecting smoke, a limit inclined surface 4c can be formed on the surface of the control panel 4. When the smoke collecting board 3 and the control panel 4 are turned out, the limit inclined surface 4c is located on the control panel. The bottom end of 4 is inclined toward the rear and upward. At this time, the outer surface of the smoke collecting board 3 and the limiting inclined surface 4c are parallel to each other. Exposed end face 4b. By setting the limiting inclined surface 4c, it is equivalent to avoiding the turning-out action of the smoke collecting board 3, and the maximum turning-out angle of the smoking collecting board 3 is enlarged, thereby enhancing the smoke collecting ability.

The control manner of the smoke collecting board 3 and the control panel 4 is not limited in this exemplary embodiment, and can be set according to the actual needs of the user. For example, if it is differentiated by the relevance of the pull-out action, a linkage control or mutual independent control can be adopted. If it is distinguished by the sequence of turning out actions, the smoke collecting board 3 can be set to follow the control panel 4 to turn out, or the control panel 4 can be set to follow the smoke collecting board 3 to turn out, or the top suction range hood can be set In order to control the control panel 4 and the smoke collecting board 3, turn out synchronously. Moreover, in the case of linkage control or mutual independent control, the above three different pull-out sequences can be realized.

Under the condition that the smoke collecting plate 3 and the control panel 4 are controlled independently of each other, the top suction range hood can also be set to trigger the smoke collecting plate 3 to be turned out or closed by manipulating the control panel 4 . The following will describe a top-suction range hood with an air purification mode in this exemplary embodiment, and this control method can be applied to the process of switching the range hood from the air purification mode to the oil fume filtering mode. Explain in detail.

By simplifying the control method, the top suction range hood can be made more intelligent. For example, a gesture-sensing trigger part 4d may be provided in the top-suction range hood, and the gesture-sensing trigger part 4d communicates with the controller of the range hood. When the user makes a specific gesture in the sensing area of the gesture-sensing triggering part 4d, the controller will receive a signal from the gesture-sensing triggering part 4d, thereby at least being able to control the control panel 4 to be turned out. After the control panel 4 is turned out, for example, the smoke collecting board 3 can be further controlled to be turned out through the user operation interface. Of course, for easier control, the turning action of the control panel 4 and the smoke collecting board 3 can be completely controlled by the gesture sensing trigger portion 4d.

Further, the gesture-sensing trigger portion 4d can be arranged on the exposed end face 4b of the control panel 4, or arranged at other conspicuous places on the surface of the range hood, so as to be more convenient for the user to control.

Although the judgment of beauty is more based on subjective impressions, relatively simple designs are often not easily outdated and are more easily accepted by the general public. Therefore, if taking into account factors such as aesthetic feeling, audience range, etc., when the control panel 4 is in the built-in state and the smoke collecting plate 3 is in the closed state, the bottom surfaces of the control panel 4 and the smoke collecting plate 3 can be set to be flush in the vertical direction. High flatness can effectively improve the aesthetics of the range hood.

During actual cooking, the cooking vapor will condense inside the cooker hood after being inhaled, and will be uniformly diverted to the oil collection cup for temporary storage. Since the oil collection cup has a fixed capacity, the oil collection cup needs to be removed for cleaning. However, not every user is familiar with the disassembly and assembly of the oil collecting cup, and for the larger oil collecting cup, disassembly and cleaning are not easy, which will adversely affect the user experience.

In order to solve the above problems, the top suction range hood may further include a liquid collection container 5, a liquid discharge port 5a and a control switch. Among them, the liquid collection container 5 is used to collect the condensed liquid (oil or condensed water) in the range hood, so that the condensed liquid is temporarily stored in the cavity. Bottom rear area of the fume collection chamber. The liquid discharge port 5a is formed on the outer wall of the liquid collection container 5 and communicates with the cavity of the liquid collection container 5. Preferably, the liquid discharge port 5a is formed on the bottom wall of the liquid collection container 5, which is more conducive to draining the condensed liquid when it is opened. The control switch is used to manually control the opening or closing of the liquid discharge port 5a. For example, the control switch can be the button 8 of the push-button switch valve. Conspicuous place to press. When the button 8 is pressed, the valve body opens the liquid discharge port 5a, and the condensed liquid is discharged; when the pressing force is removed, the button 8 is automatically reset, and the valve body closes the liquid discharge port 5a again.

It can be seen that, due to the provision of the liquid discharge port 5a and the control switch, when the liquid collection container 5 is cleaned, the temporarily stored condensed liquid can be quickly discharged without removing it as a whole, thereby reducing the difficulty of cleaning and effectively improving the user experience. experience.

In order to facilitate the cleaning of the condensed liquid after the discharge, a removable container can be added to the top suction range hood. The user can remove the movable container to manually receive the condensed liquid discharged from the drain port 5a, and then remove the condensed liquid. Pour into the sink to complete the cleaning, and the movable container can be re-installed on the top suction range hood after use. For example, a housing hook can be provided on the housing of the range hood, and a container hook can be provided on the movable container, so that the movable container can be hung on the housing of the range hood.

Alternatively, the liquid discharge port 5a can also be connected to the sewer pipe. When the button 8 is pressed, the valve body opens the liquid discharge port 5a, and the condensed liquid is directly discharged to the sewer pipe through the liquid discharge port 5a. The user only needs to press the button 8 in the whole process. No additional operations are required, further simplifying the clean-up step.

Regardless of whether the sewer pipe is connected or not, the liquid collecting container 5 can be set as a detachable container, that is, it can be detachably installed in the top suction range hood. With this arrangement, the liquid collecting container 5 can be removed in time for deeper cleaning.

Under normal circumstances, the top suction range hood is provided with a filter screen plate 6 covering the inlet of the oil fume, so that the oil fume or water vapor is formed into a condensed liquid to adhere to it when passing through, and the liquid collection container 5 is set to be able to collect the filter screen plate 6. Condensate liquid.

For the user to easily reach the key 8, it needs to be placed in a prominent position close to the user. For example, when the liquid collection container 5 is arranged at the rear end of the fume collection chamber, the button 8 can be arranged in front of the liquid collection container 5 , for example, it can be specifically arranged at the bottom of the filter screen 6 .

In order to ensure the normal ventilation of the screen plate 6, the liquid collecting container 5 cannot usually be covered under the screen plate 6. Therefore, in order to ensure the complete collection of the condensed liquid on the screen plate 6, it is necessary to The top suction range hood is provided with a flow guide structure, which is specifically arranged between the filter screen plate 6 and the liquid collection container 5 and can guide the condensed liquid on the filter screen plate 6 into the liquid collection container 5 .

Further, the screen plate 6 can be set to a folded plate shape and alternately form a plurality of screen plate high positions and a plurality of screen plate low positions along the horizontal direction, and the diversion structure includes a one-to-one correspondence arranged at the low positions of the plurality of screen screen plates. A plurality of diversion grooves 7 directly below. Since the screen plate surface between the high position of the screen plate and the low position of the screen plate is an inclined surface, and the plurality of high positions of the screen plate and the low positions of the plurality of screen plates are continuously arranged in the transverse direction, the condensed liquid on the screen plate 6 can be With the inclined surface, the flow converges to the lower position of the screen plate, and falls into the corresponding guide groove 7 . Usually, the liquid collecting container 5 is arranged at the rear and lower part of the screen plate 6, so the guide groove 7 can be set to extend in the front-rear direction and inclined downward toward the liquid collecting container 5, so that the condensation in the guide groove 7 can be eliminated. The liquid is further guided into the liquid collecting container 5, so as to realize the complete collection of the condensed liquid on the filter screen plate 6, so as to avoid the contamination caused by dripping on the kitchen countertop.

In addition, a heating element can be provided on the smoke collecting plate 3, and in the turned-out state of the smoke collecting plate 3, the heating element can continuously heat the rear wall of the smoke collecting plate 3, so as to prevent the cooking steam from being trapped on the rear wall of the smoke collecting plate 3. condensation. For example, the smoke collecting plate 3 can be set as a hollow sandwich plate, and the heating element is installed in the sandwich cavity of the hollow sandwich plate, which can not only prevent condensation, but also avoid direct contact with high-temperature steam, which is beneficial to prolong the service life, and Make the structure more compact.

In order to enrich the functions of the top suction range hood, an air purification mode can be added to the top suction range hood, that is, the top suction range hood can be switched between the air purification mode and the range hood. It belongs to one of the working modes of the top-suction range hood, and the specific working mode is not limited to this. Specifically, in the oil fume suction mode, the smoke collecting board 3 and the control panel 4 are turned out. In the air purification mode, since there is no need to form a large air volume, the smoke collecting plate 3 does not move and keeps covering the oil fume inlet, but does not completely cover the oil fume inlet, so that the air can enter the range hood through the partial opening of the oil fume inlet. At this time, the control panel 4 is still turned out. And usually, in the shutdown state (ie, the non-working mode of the top suction range hood), the smoke collecting plate 3 partially covers the oil smoke inlet, and the control panel 4 is hidden in the bottom front end area of the smoke collecting chamber.

It can be seen that the top suction range hood presents an appearance that is easy for users to distinguish in the range hood mode, air purification mode and shutdown state. Compared with the traditional range hood, the appearance is novel and very aesthetic, which is conducive to improving the user experience.

Further, the top suction range hood may further include a display screen, which may be arranged on at least one of the fume collecting hood 2, the smoke collecting board 3 and the control panel 4, and can be used in the air purification mode and suction mode of the range hood. In the lampblack mode, there are respectively distinguishable mode reminder signs, and the user operation interface in the control panel 4 can be displayed on the display screen, or can be set independently from the display screen (especially when the user operation interface includes buttons and other control components) ).

By setting the above structure, the user can quickly judge the current working mode of the range hood by observing the mode reminder sign displayed on the display screen, thereby improving the user's control and monitoring of the range hood. When the display screen shows the mode reminder logo, the aesthetics of the range hood can be enhanced, thereby enhancing the user experience.

Further, the display screen may cover the setting of the surface of the smoke collecting board 3 and/or the control panel 4. For example, the display screen may only cover the setting of the board surface of the smoking collecting board 3 or only the board surface setting of the control panel 4, or at the same time. It is arranged to cover the board surface of the smoke collecting board 3 and the board surface of the control panel 4 . In addition, the mode reminder logo can be displayed across the entire screen of the display. In this way, the mode reminder logo has a larger presentation area and is more conspicuous, which is more convenient for the user to observe and distinguish the current working mode of the range hood.

The present exemplary embodiment does not limit the specific form of the mode reminder identification, as long as different working modes of the range hood can be easily distinguished. For example, the mode reminder sign may be at least one of a pattern reminder sign, a text reminder sign, a light reminder sign and a color reminder sign, such as a light reminder sign with a starry sky pattern, etc. The reminder sign set in combination is more conducive to enhancing the beauty and distinguishing Spend.

In addition, a sound card module can also be set in the top suction range hood. In the air purification mode, the sound card module is set to be able to issue sound reminders, such as voice reminders, music reminders and other different sound reminder methods, and the sound reminder can be used alone, It can also be presented together with the above pattern reminder logo, text reminder logo, light reminder logo or color reminder logo.

In order to be more intelligent, the air quality sensor and controller can be set in the top suction range hood. Even in the shutdown state, the air quality sensor is still powered on to keep working normally, and the controller is set to be based on the air quality sensor. The sensing results of the corresponding control air purification mode on and off. Among them, the air quality sensor includes a formaldehyde sensor, a PM2.5 sensor, a TVOC sensor, a temperature and humidity sensor, etc., any one of which can be set independently, or can be set in any combination of multiple types.

In addition, when cooking is completed, the oil fume suction mode is turned off immediately, and the air purification mode is turned on following the shut down of the oil fume filter mode to deeply purify the air in the kitchen and quickly restore the kitchen environment to a fresh and clean state.

As mentioned above, when the smoke collecting plate 3 and the control panel 4 are controlled independently of each other, the top suction range hood can be set to trigger the smoke collecting plate 3 to be turned out or closed by manipulating the control panel 4 . Under this setting, when the top suction range hood needs to be switched from the air purification mode to the range hood mode, the control panel 4 can be directly manipulated to trigger the smoke collecting plate 3 to be turned out, thereby realizing the mode switching.

Due to the high frequency of use of the air purification mode, the air purification filter element 14 in the top suction range hood should be removable for cleaning or replaceable to ensure the air purification effect. For example, a filter element embedding hole may be provided on the top wall of the smoke collecting cavity, and the air purification filter element 14 may be detachably embedded in the filter element embedding hole. In order to improve the convenience of disassembly, the air purification filter element 14 can be disassembled by elastic means. ), the shell of the air purification filter element 14 is made of magnetic material. When installing or disassembling the air purification filter element 14, it is only necessary to press the shell to contact the magnetic rebounder 15, and the disassembly and assembly are quite simple and fast.

According to the current European whole-house energy efficiency standards, the development trend of range hoods will gradually transition from external exhaust type to internal exhaust type (ie, internal circulation range hoods), that is, range hoods will gradually develop to indoor exhaust. Therefore, the top suction range hood in this exemplary embodiment can be configured as an internal circulation type range hood and is provided with an exhaust port facing indoor exhaust, so as to adapt to different markets and improve product competitiveness.

It should be noted that, the above-mentioned top suction range hood may be a fully concealed range hood installed in the cabinet 9, or other different installation methods, which are not limited in this exemplary embodiment. For the fully concealed range hood, Figure 11 shows the appearance in the range hood mode, Figure 12 shows the appearance in the air purification mode, and Figure 10 shows the appearance in the shutdown state. The range hood is completely hidden in the cabinet 9 , and preferably, the bottom surfaces of the control panel 4 and the smoke collecting board 3 are vertically flush and not lower than the bottom end of the cabinet 9 .

The casing and hood of the traditional range hood cannot be easily disassembled after production. Therefore, in the actual home installation, the large size of the whole machine requires the coordination of multiple people, but despite this, it is still impossible to achieve rapid positioning and installation. , resulting in low installation efficiency and low fault tolerance. Especially for top-suction range hoods or installation in European and American markets, high labor costs will be incurred, which is not conducive to improving the market competitiveness of products.

In order to solve the above problems, as shown in FIGS. 13 to 26 , the second exemplary embodiment of the present invention provides an auxiliary assembly for a top-draft range hood (which can be used for the aforementioned top-draft range hood), which The auxiliary assembly is in the shape of a long plate and includes a mounting rail 10, an auxiliary positioning plate 11 at the end edge and an auxiliary positioning plate 12 at the bottom edge. When the auxiliary assembly is fixedly installed on the lateral side wall of the cabinet 9 , the side panel of the hood faces the range hood, and the fixed side panel faces the lateral inner side wall of the cabinet 9 .

Specifically, the mounting rails 10 are arranged along the board length direction of the auxiliary assembly. The bottom edge auxiliary positioning plate 12 is located below the installation slide rail 10, but is not connected with the installation slide rail 10, that is, the bottom edge auxiliary positioning plate 12 can be spaced or abutted on the installation slide rail 10, and the bottom edge auxiliary positioning plate 12 includes The flange 12a is positioned from its bottom edge toward the bottom edge of the fixed side panel flange. The end edge auxiliary positioning plate 11 is detachably connected to the installation slide rail 10 and the bottom edge auxiliary positioning plate 12 along the board length direction, so that the installation slide rail 10, the end edge auxiliary positioning plate 11 and the bottom edge auxiliary positioning plate 12 form a whole. For the fixed structure, when the end edge auxiliary positioning plate 11 is removed from the installation slide rail 10 , the bottom edge auxiliary positioning plate 12 can also be taken away from the position below the installation slide rail 10 . The end edge positioning flanging plate 11 is provided with an end edge positioning flange 11a, and the end edge positioning flange 11a is turned out from the outer edge of the end edge auxiliary positioning plate 11 along the board length direction toward the fixed side plate surface.

If it is necessary to locate and install the top-suction range hood by using auxiliary fittings, the lateral outer end of the top-suction range hood shall be provided with a chute which is slidingly matched with the installation slide rail 10 .

When installing, first abut the end edge positioning flange 11a on the front end surface of the lateral side wall of the cabinet 9, and the bottom edge positioning flange 12a abut on the bottom end surface of the lateral side wall of the cabinet 9, in order to realize the installation Pre-positioning of the slide rails 10, and then fix the mounting slide rails 10 on the lateral side walls of the cabinet 9 (through the fixing structure on the mounting slide rails 10, specific examples will be described below). Next, align the chute at the lateral outer end of the top suction range hood with the mounting rail 10 to push the range hood from the front opening of the cabinet 9 into the range hood installation cavity of the cabinet 9. The rail 10 is fixedly connected with the chute to complete the installation.

By setting up auxiliary assemblies, the installer can accurately locate and install the top-suction range hood without measuring the actual installation position of the hood, thus enabling single-person installation, effectively reducing the number of installers, improving installation efficiency and reducing costs.

When the top suction range hood is a fully concealed range hood installed in the cabinet 9, or if the overall appearance is to be more concise, the end edge auxiliary positioning plate 11 and the bottom edge auxiliary positioning plate 12 can be removed after the auxiliary assembly parts are fixed and installed. That is, only the installation slide rail 10 is left to be fixedly installed on the lateral side wall of the cabinet 9 , and then the range hood is installed into the cabinet 9 .

In order to simplify processing and reduce production costs, two end edge auxiliary positioning plates 11 symmetrically connected to both ends of the mounting slide rail 10 and the bottom edge auxiliary positioning plate 12 may be provided on the same auxiliary assembly. Before installing the auxiliary assembly on the lateral left wall of the cabinet 9, it is necessary to remove one of the auxiliary positioning plates 11 of the end edge of the auxiliary assembly, and then locate and install according to the above installation steps. It should be noted that when only one end edge auxiliary positioning plate 11 is removed, since the other end edge auxiliary positioning plate 11 is still fixedly connected to the installation slide rail 10 and the bottom edge auxiliary positioning plate 12, the installation slide rail 10, The end edge auxiliary positioning plate 11 and the bottom edge auxiliary positioning plate 12 which are not removed are still kept integrally fixed. Similarly, before installing the auxiliary assembly on the lateral right wall of the cabinet 9, it is also necessary to remove one of the auxiliary positioning plates 11 at the end edge of the auxiliary assembly, and then locate and install according to the above installation steps. However, for the two auxiliary assemblies installed on the left and right sides of the cabinet 9, the auxiliary positioning plates 11 connected to the opposite ends of the installation slide rails 10 should be removed in advance.

It can be seen that the auxiliary assemblies with the above-mentioned symmetrical structure can be universally installed on the lateral left and right side walls of the cabinet 9, so only one set of production molds is required, which can simplify processing and reduce costs.

Since the end edge auxiliary positioning plate 11 connected to the opposite end of the installation slide rail 10 needs to be removed in advance when installing the two auxiliary assemblies on the left and right sides, in order to avoid accidental disassembly, an installation reminder can be provided on the end edge auxiliary positioning plate 11 logo. Specifically, on the same auxiliary assembly, the installation prompt marks on the two end edge auxiliary positioning plates 11 are distinguished from each other.

For example, the two end edge auxiliary positioning plates 11 may be respectively provided with "LEFT" and "RIGHT" marks. At this time, before installing the auxiliary fittings on the lateral left side wall of the cabinet 9, the "RIGHT" mark will be marked first. The end edge auxiliary positioning plate 11 is removed, leaving the installation slide rail 10 and the end edge auxiliary positioning plate 11 connected with it with the "LEFT" mark, and then locate and install according to the above installation steps. Similarly, before installing the auxiliary fittings on the lateral right side wall of the cabinet 9, first remove the auxiliary positioning plate 11 on the end edge with the "LEFT" mark, leaving the installation slide rail 10 and the Auxiliary positioning plate 11 at the end edge marked with "RIGHT", and then locate and install according to the above installation steps.

The end edge auxiliary positioning plate 11 and the installation slide rail 10 and between the end edge auxiliary positioning plate 11 and the bottom edge auxiliary positioning plate 12 can be connected by a breakable weak connection portion 13, and the installer can directly grasp the end edge by hand. The edge assists the positioning of the plate 11 and breaks the weak link 13 to remove it. For example, referring to FIG. 15 , the weak connection parts 13 are plural and can be arranged in a dotted line shape along the board width direction of the auxiliary assembly. At this time, the auxiliary positioning plate 11 at the end edge and the mounting rail 10 and the end edge are used for auxiliary positioning. Between the plate 11 and the bottom edge auxiliary positioning plate 12, a plurality of solid parts (that is, the weak connection part 13) and a plurality of hollow parts are alternately formed in turn. Due to the existence of the plurality of hollow parts, the overall strength of the weak connection part 13 will not be too high. High and not difficult to break by hand.

In a simple structure, the mounting slide rail 10 is provided with a plurality of outer connecting holes 10a arranged at intervals along the length direction of the board. The installation slide rail 10 can be fixedly installed on the lateral side wall of the cabinet 9 by connecting the outer connecting hole 10a and the cabinet connecting hole by using fasteners (such as bolts, rivets, etc.) to connect the cabinets. Further, the outer connecting hole 10a can be set to have a larger hole depth, so that the fastener can be completely hidden in the hole after being penetrated.

In addition, the auxiliary assembly may be manufactured by various processes such as integral injection molding, integral casting, etc., which is not limited by this exemplary embodiment.

13 to 26, the third exemplary embodiment of the present invention provides an embedded installation structure of a top-draft range hood (which can be used for the aforementioned top-draft range hood), and a partial structure of the top-draft range hood As mentioned above, its embedded installation structure includes a cabinet 9 , a fume collecting hood 2 and the above-mentioned installation slide rail 10 .

The chute, the mounting rail 10 is fixedly installed on the lateral inner side wall of the cabinet 9 in the front-rear direction.

According to the above, through the sliding cooperation between the fume collecting hood chute and the mounting slide rail 10, the fume collecting hood 2 can be extended into the installation cavity of the range hood from the front side opening, thereby further fixing the top suction range hood and the mounting slide rail 10. , the installation slide rail 10 can stably support the top suction range hood.

Further, the embedded installation structure may further include a casing 1 detachably connected to the top of the fume collecting hood 2 , specifically, a detachable connection is formed between the bottom of the casing 1 and the top of the fume collecting hood 2 . For example, a sliding fit connection along the front-rear direction is formed by arranging mutually matched sliding grooves and sliding rail structures between the bottom of the cabinet 1 and the top of the fume collecting hood 2 .

Based on the above structure, when installing the top suction range hood, it is necessary to install the auxiliary assembly parts, the fume collecting hood 2 and the casing 1 in sequence, which can reduce the load of single-person installation and further improve the installation efficiency. In addition, because the casing 1 and the fume collecting hood 2 are detachable, they can be packaged independently of each other. Compared with the existing packaging method of the whole machine, the space waste is reduced by about 40%, especially in the case of large-scale transportation, the transportation is significantly reduced. The space is wasted and the one-time transportable quantity is increased, thereby greatly reducing the transport cost.

When the top suction range hood is a fully concealed range hood, the bottom end of the fume collecting hood 2 should not be lower than the bottom end of the lateral side wall of the cabinet 9, and the front end of the fume collecting hood 2 should be in line with the lateral direction of the cabinet 9. The front end of the side wall is flush, or the front end of the fume collecting hood 2 should be located behind the front end of the lateral side wall of the cabinet 9 , so as to ensure that the top suction range hood is completely housed in the range hood installation cavity of the cabinet 9 .

Since the installation position is not required to be measured when the auxiliary assembly is used, in order to achieve a fully concealed installation, the position of the installation slide rail 10 after being fixed to the range hood should be pre-considered in the design to meet the fully concealed installation requirements.
