[0036] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0038] An integral cabinet, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the cabinet includes a cabinet body 1, a range hood 4 and a cyclone assembly 2. The cabinet body 1 is used as an upper cabinet in the kitchen, and its upper end is connected to the ceiling of the kitchen. The range hood 4 includes an air collecting box assembly 42 and a range hood body 43. The air collecting box assembly 42 is arranged above the range hood body 43. The length of the range hood body 43 is greater than that of the air collecting box assembly 42. A main control circuit board is arranged in the range hood body 43. A control panel is arranged on the front side of the range hood body 43, that is, the side facing the user after installation. The control panel is provided with control buttons for controlling the operation of the range hood 4, and the control panel is electrically connected to the main control circuit board. The lower end of the range hood body 43 is provided with a narrow and long smoking port for removing cooking fumes, the wind collecting box assembly 42 is provided with a smoke exhaust duct and a smoke exhaust fan 41, the upper end of the wind collecting box assembly 42 is provided with a smoke exhaust outlet for discharging oil fumes, a check valve is installed at the smoke exhaust outlet, the smoke exhaust duct connects the narrow and long smoking port and the smoke exhaust outlet, and the smoke exhaust fan 41 is located in the smoke exhaust duct.

[0039] The cabinet body 1 is provided with a mounting position 11, which usually divides the cabinet body 1 into two parts that are not directly connected. The mounting position 11 is used to mount the range hood 4, mainly to accommodate the wind collecting box assembly 42. In order to facilitate the placement of the wind collecting box assembly 42 in the mounting position 11, the width of the mounting position 11 is slightly larger than the wind collecting box assembly 42. Since the range hood 4 will vibrate when in operation, some products are provided with shock-absorbing sealing structures on the cabinet side walls on both sides of the mounting position 11, such as shock-absorbing sponges, shock-absorbing rubber pads, etc. The front end of the cabinet body 1 is located on both sides of the installation position 11, and a shielding door 12 is provided on each side. The sum of the widths of the two shielding doors 12 cannot be less than the length of the range hood body 43. Therefore, there is a certain distance between the hinged position of the shielding door 12 and the cabinet body 1 and the installation position 11. In order to make full use of the cabinet space, a group of first storage compartments 13 are provided on each side of the installation position 11 on the cabinet body 1, or in other words, the parts of the cabinet body 1 that can be shielded when the two shielding doors 12 are closed belong to the installation position 11, so the installation position 11 has two groups of first storage compartments 13. It can be seen that the first storage compartment 13 is located above the range hood body 43, and the air collecting box assembly 42 is located between the two groups of first storage compartments 13. The shielding door 12 is used to open or close the opening of the installation position 11 toward the user side. When the shielding door 12 is opened, it can be used to install, disassemble or repair the range hood 4, or to take items from the first storage compartment 13, or to store items in the first storage compartment 13. When the shielding door 12 is closed, the first storage compartment 13 and the air collecting box assembly 42 can be shielded, making the utility model more beautiful. In addition, the following air curtain function can be realized.

[0040] In some exemplary embodiments, Figure 1As shown, the height of the shielding door 12 is adapted to the height of the cabinet body 1 , and when the shielding door 12 closes the opening of the mounting position 11 toward the user side, the air collecting box assembly 42 and the range hood body 43 of the range hood 4 are both shielded by the shielding door 12 .

[0041] In some exemplary embodiments, Figure 8 As shown, the height of the shielding door 12 is adapted to the height of the first storage compartment 13, and the depth of the first storage compartment 13 is adapted to the width of the range hood body 43. When the shielding door 12 closes the opening of the mounting position 11 toward the user side, the wind collecting box assembly 42 is shielded by the shielding door 12, and the control panel of the range hood body 43 is exposed and faces the user side, so that it is convenient for the user to manually operate the control panel.

[0042] like Figure 2 and Figure 6 As shown, the shielding door 12 includes a front plate 121 and a back plate 122, which are connected to form a mounting cavity, and the mounting cavity has a mounting cavity opening 123 facing downward, and the cyclone assembly 2 is arranged in the mounting cavity of the shielding door 12. The cyclone assembly 2 includes a cyclone bracket 21, a cyclone base 22 and a cross-flow fan 23, the cyclone bracket 21 is provided with a first cyclone opening 211 aligned with the mounting cavity opening 123, the cyclone base 22 is arranged on the cyclone bracket 21, and a plurality of cyclone exhaust holes 221 corresponding to the first cyclone opening 211 are distributed thereon, the cross-flow fan 23 is arranged on the cyclone base 22 and the air outlet end corresponds to the cyclone exhaust hole 221, and the front plate 121 is provided with a first air inlet hole 1211 corresponding to the air inlet side of the cyclone assembly 2. The crossflow fan 23 is started, and negative pressure is generated on the air inlet side of the crossflow fan 23. Air is sucked in from the first air inlet hole 1211, and discharged through the exhaust side of the crossflow fan 23 to generate exhaust air. The exhaust air is discharged downward through the cyclone exhaust hole 221, the first cyclone opening 211 and the installation cavity opening 123 to form a wind curtain. The cyclone exhaust hole 221 set on the cyclone base 22 has the effect of dividing the exhaust air of the crossflow fan 23, so that the wind curtain wind is more uniform. The cyclone exhaust hole 221 set on the cyclone base 22 has a variety of structural forms, such as honeycomb arrangement, rectangular array arrangement, etc. At the same time, the cyclone exhaust hole 221 must have a certain height to ensure that a stable rather than turbulent wind curtain wind is generated. When the shielding door 12 closes the opening of the installation position 11 toward the user side and the cyclone assembly 2 is started, the cyclone assembly 2 exhausts air downward and forms a wind curtain. The shielding door 12 and the wind curtain together form a wind shield structure. By forming a wind curtain directly in front of the range hood 4, it can effectively block the escape of oil smoke during cooking, and is suitable for working scenarios with high oil smoke cooking.

[0043] In some exemplary embodiments, the cyclone assembly 2 is fixedly disposed in the mounting cavity of the shielding door 12, such as Figure 2As shown, at this time, the cyclone support 21 can be fixed to the lower end of the installation cavity by bolts, and the cyclone base 22 and the crossflow fan 23 are installed on the cyclone support 21 near the installation cavity opening 123 at the lower end of the installation cavity.

[0044] In some exemplary embodiments, the cyclone assembly 2 can move up and down, such as Fig. 9 and Fig.10 As shown, a telescopic assembly 3 is also provided in the installation cavity of the shielding door 12, and the telescopic assembly 3 includes a telescopic driving member 31 and a telescopic main body 32. The size of the telescopic main body 32 is adapted to the installation cavity opening 123. The telescopic driving member 31 can use a vertically arranged electric cylinder. The telescopic driving member 31 is fixedly arranged in the installation cavity of the shielding door 12 with bolts. The telescopic main body 32 is connected to the lower end of the piston rod of the telescopic driving member 31. The telescopic driving member 31 can drive the telescopic main body 32 to move up and down. Through reasonable position and size settings, the telescopic driving member 31 can drive the telescopic main body 32 to extend or retract into the installation cavity. When retracting, Figure 8 As shown, when extended Fig.11 shown.

[0045] In some exemplary embodiments, in order to ensure the stable up and down movement of the telescopic body 32, a guide structure is further provided. The guide structure can have various structural forms. For example, the telescopic body 32 is configured as a rectangular shell, and its front end face and rear end face are respectively in contact with the inner wall surfaces of the front plate 121 and the back plate 122, so that the front plate 121 and the back plate 122 can play a guiding role.

[0046] The telescopic main body 32 has an accommodating cavity, and the cyclone assembly 2 is installed in the accommodating cavity. The front wall of the telescopic main body 32 is provided with a second air inlet hole 321 corresponding to the air inlet side of the cyclone assembly 2, and the bottom thereof is provided with a second cyclone opening 322 connecting the installation cavity opening 123 and the exhaust side of the cyclone assembly 2. The cyclone bracket 21 of the cyclone assembly 2 is provided with a first cyclone opening 211 aligned with the second cyclone opening 322. When the cyclone assembly 2 is needed, the telescopic driving member 31 is started first. The telescopic driving member 31 drives the telescopic body 32 and the cyclone assembly 2 arranged in the telescopic body 32 to extend downward out of the installation cavity of the shielding door 12. At this time, the second air inlet hole 321 arranged on the front wall of the telescopic body 32 realizes good communication with the external air. Then the cross-flow fan 23 is started, and negative pressure is generated on the air inlet side of the cross-flow fan 23. Air is sucked in from the second air inlet hole 321 and discharged through the exhaust side of the cross-flow fan 23 to generate exhaust wind. The exhaust wind is discharged downward through the cyclone exhaust hole 221, the first cyclone opening 211, the second cyclone opening 322 and the installation cavity opening 123 to form a wind curtain. When the shielding door 12 closes the opening of the mounting position 11 toward the user side and the telescopic driving member 31 is started first, the telescopic main body 32 and the cyclone assembly 2 arranged in the telescopic main body 32 are driven to extend downward out of the mounting cavity of the shielding door 12, and then the cyclone assembly 2 is started. At this time, the cyclone assembly 2 can smoothly absorb air and exhaust air downward to form a wind curtain. The wind curtain generated by the shielding door 12 and the cyclone assembly 2 together form a wind shield structure. By forming a wind curtain directly in front of the range hood 4, it can effectively prevent the escape of oil smoke during cooking, and is suitable for working scenarios with high oil smoke cooking.

[0047] In some exemplary embodiments, Figure 3 , Figure 6 and Figure 7As shown, a PM2.5 detection module 5 is also provided in the installation cavity of the shielding door 12. The PM2.5 detection module 5 includes a detection bracket 51, a detection module 52 and a sealing sponge 53. The detection bracket 51 is connected to the front side wall of the installation cavity and forms a detection cavity with the front side wall of the installation cavity. A support rib 511 extends upward from the bottom of the detection cavity. The support rib 511 divides the detection cavity into an air inlet cavity 512 and an air outlet cavity 513. The detection module 52 is provided on the support rib 511, and a buckle extends upward from the back plate of the detection bracket 51. The detection module 52 is clamped between the support rib 511 and the buckle, so that the detection module 52 is installed more firmly. A detection air inlet 521 and a detection air outlet 522 are provided on the shell of the detection module 52. An induced draft fan is provided in the shell of the detection module 52. The air inlet and the air outlet of the induced draft fan are respectively connected to the detection air inlet 521 and the detection air outlet 522 provided on the shell of the detection module 52. The sealing sponge 53 is placed on the supporting rib 511 and squeezed between the detection module 52 and the front wall of the installation cavity. The sealing sponge 53 also plays the role of partial sealing, buffering and stabilizing the detection module 52. The sealing sponge 53 is provided with a first avoidance position 531 and a second avoidance position 532 corresponding to the detection air inlet 521 and the detection air outlet 522, so as to prevent the sealing sponge 53 from blocking the detection air inlet 521 and the detection air outlet 522, thereby affecting the normal use of the detection module 52. The shielding door 12 is provided with a detection air hole 1212, a part of which is connected to the air inlet cavity 512, and the other part is connected to the exhaust cavity 513. When the PM2.5 detection module 5 is working, the induced draft fan arranged inside the detection module 52 is started, and the air in the kitchen is sucked into the detection module 52 through part of the detection air holes 1212 and the detection air inlet 521 for PM2.5 detection, and the detected air is discharged through the detection air outlet 522 and part of the detection air holes 1212.

[0048] In order to better use the detection results of the PM2.5 detection module 5, the control system of the range hood 4 is connected to the PM2.5 detection module 5 signal, and the signal connection method can be a wired connection or a wireless signal connection such as Bluetooth. The wired connection has good stability, and the PM2.5 detection module 5 can be powered by the range hood 4. However, to achieve the wired connection between the PM2.5 detection module 5 and the range hood 4, wiring is required, the line structure is complex, and operations such as opening holes are also required. The wireless signal connection method does not require the use of wires to connect the PM2.5 detection module 5 and the range hood 4, but it is necessary for both the PM2.5 detection module 5 and the range hood 4 to be equipped with wireless transceiver devices such as Bluetooth chips, and it is more difficult to power the PM2.5 detection module 5. Powering through wires and sockets requires wiring. Using batteries for power supply is prone to failure to replace batteries in time or fail to charge in time, resulting in no power available for the PM2.5 detection module 5, and there are problems of unstable power supply and unstable use of the PM2.5 detection module 5. In the cabinet products available, the structural form used for the connection between the PM2.5 detection module 5 and the range hood 4 can be customized according to user requirements to meet the personalized needs of different users.

[0049] When the smoke exhaust fan 41 of the range hood 4 is started, the control system of the range hood 4 adjusts the speed of the smoke exhaust fan 41 of the range hood 4 according to the PM2.5 content value detected by the PM2.5 detection module 5, or turns off the smoke exhaust fan 41. After the smoke exhaust fan 41 of the range hood 4 is turned off, when the PM2.5 content value detected by the PM2.5 detection module 5 is greater than the set value, the control system of the range hood 4 starts the smoke exhaust fan 41 again. In this way, the PM2.5 concentration in the environment where the range hood 4 is located is detected by the PM2.5 detection module 5, and the start and stop and speed of the smoke exhaust fan 41 of the range hood 4 are automatically controlled according to the detection result and the set value, so that the energy-saving operation and automatic control of the range hood 4 can be achieved, making the utility model more energy-saving and intelligent.

[0050] In some exemplary embodiments, Fig.10 and Fig.12 As shown, the PM2.5 detection module 5 is fixedly arranged in the installation cavity of the shielding door 12, and the cyclone component 2 is movably arranged and is driven by the telescopic driving member 31 of the telescopic component 3. In addition to this arrangement, the PM2.5 detection module 5 can also be arranged to be movable, or the PM2.5 detection module 5 can be arranged in the telescopic body 32 of the telescopic component 3, so that the PM2.5 detection module 5 obtains the same movement mode as the cyclone component 2. It should be noted that when the PM2.5 detection module 5 is arranged in the telescopic body 32 of the telescopic component 3, the shell of the telescopic body 32 corresponding to the detection air inlet 521 and the detection air outlet 522 of the PM2.5 detection module 5 should also be provided with an adaptive detection ventilating hole.

[0051] In some exemplary embodiments, the PM2.5 detection module 5 and the cyclone component 2 are both connected to the main control circuit board of the range hood 4, and the main control circuit board of the range hood 4 is provided with an MCU chip. The PM2.5 detection module 5 is used to detect the fume concentration in the kitchen and transmit the detection value to the MCU chip on the main control circuit board of the range hood 4. The MCU chip is provided with a concentration threshold. When the detection value of the PM2.5 detection module 5 is greater than the concentration threshold, the MCU chip controls the exhaust fan 41 to increase the speed to generate greater suction, and / or controls the cyclone component 2 to start and generate a wind curtain to reduce the escape of fume and reduce the kitchen fume concentration. Moreover, this control method is automatic control, which is a very high product selling point and is conducive to the sale of the integrated cabinet products produced based on the utility model.

[0052] In addition, the utility model provides an integrated cabinet with a range hood, which can be made into a fixed-size product that meets the sizes of most kitchens, or customized according to the size of the user's kitchen. Compared with the existing user purchasing a range hood and then having a carpenter or cabinet manufacturer make a cabinet according to the size of the range hood, it is easier to control the size, so that the size of the cabinet and the range hood is better matched, and it is also easier to achieve a better aesthetics, which has a competitive advantage.

[0053] In summary, the cabinet provided by the utility model is provided with a mounting position 11 for installing the range hood 4, and shielding doors 12 that can be opened and closed are provided at both ends of the mounting position 11. When the shielding door 12 is opened, it is convenient for installing and disassembling the range hood 4. When the shielding door 12 is closed, it is located directly in front of the range hood 4. An installation cavity is provided in the shielding door 12, and a cyclone assembly 2 and a PM2.5 detection module 5 are provided in the installation cavity. When the shielding door 12 is closed, the cyclone assembly 2 can exhaust air downward and form a wind curtain located in front of the range hood 4. The shielding door 12 and the wind curtain together form a wind shielding structure located in front of the range hood 4. When the shielding door 12 is closed and the cyclone assembly 2 is in operation, a wind curtain is formed directly in front of the range hood 4, which can effectively prevent the escape of oil smoke during cooking, and is suitable for working scenes with high oil smoke cooking. The PM2.5 detection module 5 is connected to the control system signal of the range hood 4. When the exhaust fan 41 of the range hood 4 is started, the control system of the range hood 4 adjusts the speed of the exhaust fan 41 of the range hood 4 according to the PM2.5 content value detected by the PM2.5 detection module 5, or turns off the exhaust fan 41. After the exhaust fan 41 of the range hood 4 is turned off, when the PM2.5 content value detected by the PM2.5 detection module 5 is greater than the set value, the control system of the range hood 4 starts the exhaust fan 41 again.
