Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, and in particular to a panel assembly and a range hood having the same. Background Art

[0002] When users are cooking, a lot of oil smoke will be generated. The oil smoke will spread in the cooking space and pollute the cooking space. Cooks who work in an environment full of oil smoke will inhale oil smoke for a long time, which will harm their health. The range hood is an electrical appliance used to exhaust the oil smoke generated by users' cooking from the kitchen. The range hood is located above the stove. When users are cooking, the range hood is started, and the exhaust fan of the range hood forms a negative pressure at the air intake of the range hood, so that the oil smoke generated by users' cooking enters the air collecting chamber of the range hood through the air intake, and then is exhausted by the range hood, avoiding users from inhaling a lot of oil smoke when cooking. Although the range hood can exhaust the oil smoke generated by users' cooking, when users are cooking, the power control of the exhaust fan of the range hood depends largely on personal experience. Users do not know the actual purification effect of the range hood on the oil smoke, and will not adjust the power of the exhaust fan of the range hood in time according to the oil smoke escape situation.

[0031] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0032] See also Figures 1 to 3The utility model discloses a panel assembly. The panel assembly disclosed in the utility model is used for a range hood, and includes a display panel 1, a switch control board assembly 2 and a PM2.5 detection unit 3. The display panel 1 is provided with a display area 11 and a mounting through hole 12; the switch control board assembly 2 is connected to the inner side of the display panel 1, and at least has a PM2.5 display module thereon, and the display effect of the PM2.5 display module is displayed through the display area 11; the PM2.5 detection unit 3 is connected to the inner side of the display panel 1, and its detection air intake channel is connected to the external airflow through the mounting through hole 12; the switch control board assembly 2 and the PM2.5 detection unit 3 are connected to the main control board of the range hood, the PM2.5 display module is used to display the detection result of the PM2.5 detection unit 3, and the display area 11 on the display panel 1 is used to display the display effect of the PM2.5 display module. The panel assembly of the utility model is provided with a PM2.5 detection unit 3. When it is applied to the range hood, after the range hood is running, air will enter the detection air intake channel of the PM2.5 detection unit 3 through the mounting through hole 12 on the display panel 1 and be detected by the PM2.5 detection unit 3. The PM2.5 detection unit 3 will detect the air quality entering its detection air intake channel in real time, and transmit the detection result to the main control board of the range hood. The main control board of the range hood displays the detection result of the PM2.5 detection unit 3 through the PM2.5 display module. The display effect of the PM2.5 display module is displayed through the display area 11, so that the user can understand the purification effect of the range hood on the oil fume, and remind the user to increase the operating power of the exhaust fan of the range hood when the PM2.5 content in the air exceeds the standard, so as to improve the suction force of the range hood on the oil fume. The panel assembly of the utility model is provided with a mounting through hole 12 on the panel which is connected to the detection air inlet passage of the PM2.5 detection unit 3, so that when oil smoke escapes, the PM2.5 detection unit 3 can react promptly and remind the user in time, thereby reducing the escape of oil smoke and the amount of oil smoke inhaled by the user.

[0033] The display effect of the PM2.5 display module can be digital, and the digital represents the PM2.5 content value detected in real time. The user can know the purification effect of the range hood on the oil fume through the digital change; the display effect of the PM2.5 display module can also be color change. When the PM2.5 content in the air detected by the PM2.5 detection unit 3 exceeds the standard, the PM2.5 display module can display a color. When the PM2.5 content in the air increases, the color displayed by the PM2.5 display module can gradually darken. Through the extended depth changes, the user can understand the purification effect of the range hood on the oil fume and the escape of the oil fume.

[0034] See also Figure 2 and Figure 3The panel assembly of the utility model, the PM2.5 detection unit 3 includes a cover plate 31, a shell 32 and a PM2.5 detection element 33. The cover plate 31 is located on the outer side of the display panel 1 and covers the mounting through hole 12. A detection port 311 is provided on the cover plate 31. The projection of the detection port 311 onto the display panel 1 falls into the mounting through hole 12. The shell 32 is located on the inner side of the display panel 1 and is connected to the cover plate 31. The PM2.5 detection element 33 is arranged in the shell 32, which has a detection air inlet channel, and the detection air inlet channel is connected to the external airflow through the detection port 311. Usually, the display panel 1 is a glass panel, and it is difficult to drill holes on the glass panel to fix the PM2.5 detection unit 3. If the PM2.5 detection unit 3 is fixed to the inner side of the display panel 1 by means of glue, it is difficult to remove the PM2.5 detection unit 3 from the display panel 1 when the PM2.5 detection unit 3 needs to be repaired; and fixing the PM2.5 detection unit 3 by gluing the mounting bracket on the inner side of the display panel 1 not only occupies a relatively large space, but also makes the distance between the entrance of the detection air intake channel of the PM2.5 detection unit 3 and the mounting through hole 12 too large, so that the oil smoke on the front side of the display panel 1 can easily enter the inner side of the display panel 1 through the mounting through hole 12, and the oil smoke may contaminate the electrical components on the switch control board assembly 2, affecting the life of the switch control board assembly 2. In the panel assembly of the utility model, the cover plate 31 and the shell 32 of the PM2.5 detection unit 3 are respectively arranged on the outside and inside of the display panel 1. After the cover plate 31 and the shell 32 are connected, the cover plate 31 presses the display panel 1 from the outside of the display panel 1, and the shell 32 presses the display panel 1 from the inside of the display panel 1, and the cover plate 31 covers the mounting through hole 12, so that the detection port 311 on it is connected with the detection air intake channel of the PM2.5 detection element 33, so that when the PM2.5 detection element 33 is started, the air outside the display panel 1 enters the detection air intake channel through the detection port 311, and the oil smoke will not enter the inside of the display panel 1 through the mounting through hole 12 to pollute the electrical components on the switch control board assembly 2. In addition, the panel assembly of the utility model is fixed on the display panel 1 through the connection of the cover plate 31 and the shell 32, so that when maintenance is required, it is convenient to remove the PM2.5 detection unit 3 from the display panel 1.

[0035] See also Figure 2 and Figure 3In the panel assembly of the utility model, the PM2.5 detection unit 3 also includes a mesh plate 34, which is installed in the detection port 311. A plurality of detection holes 341 are evenly distributed on the mesh plate 34, and the detection air inlet channel is connected to the external airflow through the detection holes 341. The mesh plate 34 is arranged in the detection port 311, and the user cannot directly see the PM2.5 detection element 33 from the outside of the display panel 1, so that the appearance of the panel assembly can be beautiful. When the PM2.5 detection unit 3 is started, the PM2.5 detection element 33 works, and the air outside the display panel 1 enters the detection air inlet channel of the PM2.5 detection element 33 through the detection holes 341 and is detected by the PM2.5 detection element 33.

[0036] See also Figure 2 and Figure 3 In the panel assembly of the utility model, the thickness of the mesh plate 34 is less than the thickness of the cover plate 31, and the inner side surface of the mesh plate 34 is flush with the inner side surface of the cover plate 31, so that the outer side surface of the mesh plate 34 is recessed in the detection port 311. The mesh plate 34 is set and the thickness of the mesh plate 34 is less than the thickness of the cover plate 31. When the mesh plate 34 is installed in the detection port 311, the inner side surface of the mesh plate 34 is flush with the inner side surface of the cover plate 31. When the cover plate 31 is installed on the display panel 1, the inner side surface of the cover plate 31 is closely attached to the outer side surface of the display panel 1. The mesh plate 34 passes through the cover plate 31 toward the detection air intake channel of the PM2.5 detection element 33, which can shorten the time for the airflow to enter the detection air intake channel of the PM2.5 detection element 33 through the detection hole 341, so that the PM2.5 detection element 33 responds to the escape of oil smoke more promptly.

[0037] See also Figure 3 In the panel assembly of the utility model, a connecting column 312 is provided on the cover plate 31, and a connecting hole 321 is provided on the shell 32. The connecting column 312 extends through the mounting through hole 12 into the inner side of the display panel 1 and is connected with the connecting hole 321. When the PM2.5 detection unit 3 is installed on the display panel 1, the connecting column 312 on the cover plate 31 is extended from the mounting through hole 12 into the inner side of the display panel 1, and then the connecting hole 321 on the shell 32 is aligned with the connecting column 312 close to the inner side of the display panel 1, and finally the cover plate 31 and the shell 32 are connected together by a connecting member passing through the connecting hole 321 and the screw hole on the connecting column 312, and the PM2.5 detection unit 3 is fixed to the display panel 1, which is convenient for disassembly and assembly and maintenance.

[0038] See also Figure 2In the panel assembly of the utility model, the PM2.5 detection element 33 has an air intake port 331 and an air exhaust port 332, and both the air intake port 331 and the air exhaust port 332 face the detection port 311 and are aligned with the detection port 311. When the PM2.5 detection element 33 is started, the air outside the display panel 1 enters the detection air inlet channel of the PM2.5 detection element 33 through the detection hole 341 and the corresponding part of the air intake port 331, and after being detected by the PM2.5 detection element 33, the air is discharged to the outside of the display panel 1 through the corresponding part of the detection hole 341 and the air exhaust port 332, and the air detected by the PM2.5 detection element 33 will not be discharged to the inside of the display panel 1, so as to avoid contaminating the electrical components on the switch control board assembly 2.

[0039] See also Figures 4 to 6 The utility model also discloses a range hood, which adopts the above-mentioned panel assembly. The range hood of the utility model includes a range hood body 4, which has an electric control cavity. The display panel 1 is connected to the front side of the range hood body 4 and seals the electric control cavity. The switch control panel assembly 2 and the PM2.5 detection unit 3 are placed in the electric control cavity. In the range hood of the utility model, when the range hood is exhausting smoke, the PM2.5 detection unit 3 detects the air in the detection air inlet channel of the PM2.5 detection unit 3 through the outside of the display panel 1 in real time. After the detection result of the PM2.5 detection unit 3 is sent to the main control board of the range hood, the main control board of the range hood displays the detection result through the PM2.5 display module. The display area 11 on the display panel 1 displays the display effect of the PM2.5 display module, which can enable the user to clearly understand the escape of oil smoke in the current operation state of the range hood. When the PM2.5 detection unit 3 detects that the PM2.5 content in the air exceeds the standard, the user can increase the operating power of the range hood to increase the range hood's suction force on oil fumes until the PM2.5 detection unit 3 detects that the PM2.5 content in the air meets the standard.

[0040] See also Figure 6 The range hood of the utility model also includes an air curtain assembly 5, which is arranged in the electric control chamber. An air curtain air inlet hole 41 is arranged on the top plate of the electric control chamber, and an air curtain air exhaust hole 42 is arranged on the bottom plate of the electric control chamber. The air curtain assembly 5 sucks air through the air curtain air inlet hole 41 and exhausts air through the air curtain air exhaust hole 42 to form an air curtain. When the range hood is running, the air curtain assembly 5 operates, and the air curtain assembly 5 sucks air through the air curtain air inlet hole 41 and exhausts air through the air curtain air exhaust hole 42. The air exhausted by the air curtain assembly 5 forms an air curtain located between the stove and the user, and the air curtain can block the escape of oil smoke. The air curtain assembly 5 includes a cross-flow fan and a cyclone engine lower cover. The air suction side of the cross-flow fan corresponds to the air curtain air inlet hole 41, and the air outlet side of the cross-flow fan is sealed in the air duct of the cyclone engine lower cover. The air sucked by the cross-flow fan enters the air duct of the cyclone engine lower cover, and then is discharged downward through the air curtain air exhaust hole 42.

[0041] The range hood of the utility model has an air curtain assembly 5. When the range hood is running and extracting oil smoke, the air curtain assembly 5 is in operation. When the PM2.5 detection unit 3 detects that the PM2.5 content in the air exceeds the standard, the main control board of the range hood first increases the operating power of the cross-flow fan of the air curtain assembly 5 to increase the exhaust speed of the air curtain assembly 5. If the PM2.5 detection unit 3 detects that the PM2.5 content in the air has a decreasing trend, it means that increasing the flow rate of the air curtain wind can solve the problem of oil smoke escape; if the PM2.5 detection unit 3 detects that the PM2.5 content in the air has a trend of continuing to increase, and the power of the air curtain assembly 5 has increased to the maximum value, the main control board of the range hood will increase the power of the exhaust fan of the range hood to reduce the oil smoke escape by increasing the amount of oil smoke sucked by the range hood.

[0042] See also Figure 6 The range hood of the present invention also includes a smoke exhaust fan 6, which is arranged in the air collecting chamber of the range hood body 4. The main control board of the range hood adjusts the power of the smoke exhaust fan 6 according to the detection result of the PM2.5 detection unit 3; when the PM2.5 detection unit 3 detects that the PM2.5 content in the air exceeds the standard and the power of the air curtain assembly 5 has increased to the maximum value, if the PM2.5 detection unit 3 detects that the PM2.5 content in the air has a trend of continuing to increase, the main control board of the range hood will automatically increase the power of the smoke exhaust fan of the range hood, thereby reducing the escape of oil smoke by increasing the amount of oil smoke sucked by the range hood.

[0043] See also Figure 6 The range hood of the utility model further includes a smoke exhaust fan 6, and the main control board of the range hood turns on or off the smoke exhaust fan 6 according to the detection result of the PM2.5 detection unit 3. After the range hood is turned off, the PM2.5 detection unit 3 continues to detect the PM2.5 content in the air. If the PM2.5 content in the air detected by the PM2.5 detection unit 3 exceeds the standard at this time, it is possible that the oil smoke flows back from the air intake port of the range hood. When the smoke exhaust fan 6 of the range hood is turned off, the main control board of the range hood starts the smoke exhaust fan 6 according to the PM2.5 content in the air detected by the PM2.5 detection unit 3, so that the smoke exhaust fan sucks the oil smoke, and sucks and discharges the oil smoke that flows back into the cooking space; in this process, the PM2.5 detection unit 3 continues to detect the PM2.5 content in the air. When the PM2.5 content in the air detected by the PM2.5 detection unit 3 reaches the standard, the main control board of the range hood turns off the smoke exhaust fan 6.

[0044] In the range hood of the present invention, the switch control panel assembly 2 is also provided with a wind speed display module for displaying the power of the smoke exhaust fan 6, and the display effect of the wind speed display module is displayed through the display area 11. When the smoke exhaust fan 6 is running, the wind speed display module displays the wind speed of the smoke exhaust fan 6. The display effect of the wind speed display module can be digital, using digital to display the current power and / or wind speed of the smoke exhaust fan 6; the display effect of the wind speed display module can also be an icon, using different icons to display the power and gear of the smoke exhaust fan 6.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
