Description

  The present invention relates to a range hood capable of automatic cleaning.

  A range hood that discharges air containing oil generated by cooking has become widespread. This range hood includes a housing having an intake port and an exhaust port, a blower mechanism that sends air from the intake port to the exhaust port, and a rectifying plate provided at the intake port. In the air blowing process, oil separated from the air adheres to the blowing mechanism and the current plate.

The range hood of Patent Literature 1 includes a blower casing that houses an exhaust impeller, and a nozzle that blows water from a water storage tank into the blower casing. Thereby, the water blown from the nozzle collides with the rotated exhaust impeller to peel and remove the oil film, and the water containing the oil is scattered and washed by centrifugal force.

  Patent Document 2 discloses a technology in which a blower mechanism is constituted by an impeller and a power transmission member, and a filter attached around the power transmission member is automatically cleaned. The range hood of Patent Document 2 includes a blower box that houses an impeller and a power transmission member, and a nozzle that blows water from a tank to a filter. Thereby, water collides with the filter impregnated with the detergent to remove the oil adhering to the filter.

JP 2013-44471 A Japanese Patent Laying-Open No. 2006-13229

  The air flow path inside the housing has an inner surface of the rectifying plate, and the oil separated from the collided air adheres to the inner surface of the rectifying plate or the oil separated from the air colliding with the inner surface of the housing. Falls on the current plate and adheres to the inner surface of the current plate. For this reason, in the conventional range hood, it was necessary to remove a baffle plate and to wash manually. Since it is troublesome to remove the current plate and clean it, some users leave it for a long period of time and the oil remains on the current plate, making it difficult to clean.

  Therefore, a range hood that can maintain the current plate in a clean state without bothering the user is desired.

  The characteristic configuration of the range hood according to the present invention includes a housing having an intake port and an exhaust port, a blower mechanism that is disposed inside the housing and sends air from the intake port to the exhaust port, and an interior of the housing A liquid supply pipe connected to a liquid supply source, a rectifying plate provided at the intake port and having a liquid discharge port, and a drainage pipe connected to the drainage port, The liquid supply pipe is provided with a blowout port for blowing out the liquid supplied from the liquid supply source toward the inner surface of the rectifying plate, and the inner surface of the rectifying plate is cleaned with the liquid blown out from the blower outlet. There is in point to do.

  In this configuration, the inner surface of the rectifying plate is cleaned with the liquid blown from the outlet of the liquid supply pipe connected to the liquid supply source. For this reason, the oil adhering to the inner surface of the current plate can be automatically washed.

  Further, since the outlet is configured to blow liquid toward the inner surface of the rectifying plate, the liquid can collide with the inner surface of the rectifying plate to forcibly wash the oil adhering to the inner surface of the rectifying plate. it can. Moreover, since the drainage port is provided in the rectifying plate, it is possible to discharge the liquid mixed with oil each time, and the rectifying plate can be kept clean.

  Thus, the range hood which can maintain a baffle plate in a clean state without bothering a user was able to be provided.

  Another configuration is that the inner surface of the current plate has an inclined surface so that the drainage port is lower than a position directly below the outlet.

  As in this configuration, if the current plate has an inclined surface so that the drainage port is lower than the position directly below the outlet, the liquid that has collided with the inner surface of the current plate flows smoothly along the inclined surface. As a result, the liquid does not remain on the inner surface of the current plate. As a result, there is no inconvenience that the remaining liquid evaporates and the oil component reattaches to the inner surface of the current plate, and the current plate can be kept clean.

  In another configuration, the drain port is formed on one end side of the rectifying plate, and the blowout port blows liquid to the other end side of the rectifying plate opposite to the drain port. The inner surface of the current plate is inclined so that the liquid flows from the other end side toward the one end side.

  If a blower outlet and a drain outlet are provided at both ends of the current plate as in this configuration, the liquid can be spread over the entire area of the inner surface of the current plate. In addition, since the liquid colliding with the inner surface of the current plate flows smoothly along the inclined surface and is discharged from the drain port, the liquid does not remain on the inner surface of the current plate. As a result, the entire area of the inner surface of the current plate can be kept clean.

  Another configuration is that the air outlet is configured to be switchable between a first air outlet that ejects the liquid in a mist state and a second air outlet that ejects the liquid in a lump shape.

  If the air outlet is formed so that the mist and lump liquid can be blown out as in this configuration, for example, after the oil adhering to the current plate is softened and floated by the mist, the oil component is forcibly discharged with the lump liquid. It can be washed away. As a result, the cleaning efficiency of the current plate can be increased.

  Other configurations include a first input unit capable of inputting an operation command and a stop command for the blower mechanism, a second input unit capable of inputting a cleaning command for the rectifying plate, and a control unit for controlling the operation of the outlet. The control unit mists liquid from the first outlet when the stop command is input to the first input unit and the cleaning command is input to the second input unit. The liquid is ejected from the second air outlet after a predetermined time has elapsed.

  In this configuration, after the oil adhering to the current plate is softened and floated with mist, the oil is forcibly washed away with a block liquid. As a result, the cleaning efficiency of the current plate can be increased. Further, since the current plate is washed after the air blowing mechanism is stopped, the mist is not forcibly discharged by the air blowing mechanism. In addition, since the cleaning is started only by inputting the cleaning command, it does not bother the user.

The water supply pipe 3 is provided with a nozzle 31 (an example of an air outlet) that blows hot water supplied from the hot water supply source 30 toward the inner surface 40 of the rectifying plate 4 (the surface of the rectifying plate 4 that is in contact with the internal space 10). (See FIG. 3). A first opening / closing valve 3 a is provided on the water supply pipe 3. By opening the first on-off valve 3a, the inner surface 40 of the rectifying plate 4 is washed with the hot water blown from the nozzle 31.

  The nozzle 31 is configured to be switchable between a first air outlet 31a that ejects hot water in a mist form and a second air outlet 31b that ejects hot water in a lump. In this switching structure, the first air outlet 31a and the second air outlet 31b may be provided separately and opened and closed by an on-off valve (not shown), and the second air outlet 31b is arranged at the center, It is good also as a structure which comprises the one blower outlet 31a by the microhole arrange | positioned around the 2nd blower outlet 31b, and switches the 1st blower outlet 31a and the 2nd blower outlet 31b with a switching valve (not shown). It may be in any form.

  In addition, the range hood X includes a branch pipe 32 that is branched from the water supply pipe 3 and has a third outlet 32 a that blows warm water toward the blower mechanism 2. On the path of the branch pipe 32, a second on-off valve 32b is provided. By opening the second on-off valve 32b, the inside of the blower mechanism 2 is washed with the hot water blown from the third outlet 32a. The warm water after washing is discharged from a small hole 21 a provided at the bottom of the air blowing casing 21, falls to the rectifying plate 4, and is discharged from a drain port 41 of the rectifying plate 4 described later. The branch pipe 32 that cleans the blower mechanism 2 may be omitted, and the third outlet 32a can be switched between an outlet that ejects hot water in a mist state and an outlet that ejects hot water in a lump. It may be configured.

  As shown in FIG. 2, the rectifying plate 4 is arranged in a state of closing the center of the air inlet 1 a while being fixed to the housing 1. This baffle plate 4 has a function of narrowing the opening area of the intake port 1a, and increases the suction speed of air containing oil generated by cooking. The rectifying plate 4 is formed in a rectangular shape when viewed from the bottom, and is provided with intake ports 1 a along three sides, and one end constituting the remaining one side is in close contact with the housing 1. The air inlet 1a may be provided along the four sides of the rectifying plate 4 without bringing one end of the rectifying plate 4 into close contact with the housing 1, or may be provided on at least one of the four sides. It is not limited. In the case where a gap is provided between one end of the rectifying plate 4 and the housing 1 without bringing the one end of the rectifying plate 4 into close contact with the housing 1, the intake port 1 a is provided on the entire circumference of the rectifying plate 4. Can be reliably increased. The fixing of the rectifying plate 4 is not limited to the form of fixing to the housing 1, but may be a form of fixing to the wall or fixing to another member.

  As shown in FIG. 3, the rectifying plate 4 has a bottom portion 4a and side walls 4b extending upward from four sides of the bottom portion 4a. A drainage port 41 (an example of a drainage port) penetrating through the center of the bottom 4 a is provided on one end side in close contact with the housing 1 of the rectifying plate 4, and the drainage pipe 5 is connected to the drainage port 41. The rectifying plate 4 is formed by pressing a plate-like member (stainless steel plate, steel plate or the like), and has a box shape having an opening on the inner space 10 side of the housing 1. Here, a surface of the bottom portion 4 a of the rectifying plate 4 on the side of the internal space 10 of the housing 1 is defined as an inner surface 40 of the rectifying plate 4.

  The inner surface 40 of the rectifying plate 4 is subjected to oil repellency processing, water repellency processing or hydrophilic processing, thereby preventing sticking of oil contained in the air. A nozzle 31 is provided immediately above the other end side of the rectifying plate 4 opposite to one end side of the rectifying plate 4 provided with the drain port 41. Further, the inner surface 40 of the rectifying plate 4 is inclined so as to be separated from the internal space 10 from the other end side of the rectifying plate 4 toward the one end side. As a result, the hot water and mist blown from the nozzle 31 smoothly flow down along the inner surface 40 of the inclined rectifying plate 4 and are discharged from the drain port 41. In addition, without providing an inclined surface from the other end side of the rectifying plate 4 toward the one end side, it is only necessary to have an inclined surface so that the drain port 41 is lower than a position directly below the nozzle 31, and there is no particular limitation. . For example, you may make it incline so that it may space apart from the internal space 10 from the intermediate position of the baffle plate 4 to the drain port 41. Further, the inner surface 40 of the rectifying plate 4 may not be inclined.

  The drain pipe 5 is connected to a drain port 41 provided at one end of the rectifying plate 4, and is joined to the sewer pipe while being embedded in the wall W.

  FIG. 4 is a functional block diagram showing functional units provided in the range hood X. Each functional unit in the present embodiment is constructed by hardware and / or software with a processor and memory for executing various processes as a core.

  The range hood X includes a remote controller R (an example of an input unit, and the input unit may be built in the range hood X) from which the user can input the operation of the range hood X, and the remote controller R. And a control unit C that receives the output signal and controls the operation of the range hood X. The means for transmitting the output signal from the remote controller R to the control unit C may be wireless communication or wired communication.

  The remote controller R includes an operation button 51 (an example of a first input unit) that can input an operation command for the blower mechanism 2, and a stop button 52 (an example of a first input unit) that can input a stop command for the blower mechanism 2. And a cleaning button 53 (an example of a second input unit) capable of inputting a cleaning instruction for the range hood X. The remote controller R also has other function buttons such as a power button, but the description is omitted.

  The cleaning button 53 is configured to be able to input at least a cleaning command for the current plate 4. As described above, when the blower mechanism 2 has a cleaning function, the blower mechanism 2 is cleaned in addition to the current plate 4 by pressing the cleaning button 53. The operation button 51 and the stop button 52 may be configured to be able to change on / off with one button, or may be configured with two buttons. Further, the cleaning button 53 may be provided with two buttons for cleaning the rectifying plate 4 and two buttons for cleaning the blower mechanism 2, or a separate cleaning stop button may be provided.

  The control unit C determines whether or not the operation of the range hood X is necessary based on an output signal from the remote controller R, and a blower mechanism that controls the operation of the blower mechanism 2 based on the determination result of the determination unit 61. The control unit 62, the cleaning control unit 63 that controls at least the cleaning process of the current plate 4 in response to the determination result of the determination unit 61, and the determination result of the determination unit 61 notifies the user of the state of the range hood X. A notification unit 64.

  When the user presses the operation button 51, the determination unit 61 transmits an operation signal of the blower mechanism 2 to the blower mechanism control unit 62, and when the user presses the stop button 52, the determination unit 61 sends a stop signal of the blower mechanism 2. This is transmitted to the control unit 62. Moreover, the determination part 61 determines whether the total operation time of the ventilation mechanism 2 is more than 1st predetermined time T1 (for example, 1 hour). Further, when the stop button 52 and the cleaning button 53 are pressed, the determination unit 61 transmits at least a cleaning command for the current plate 4 to the cleaning control unit 63. At this time, the determination unit 61 determines whether or not the time for ejecting the mist from the first air outlet 31a is the second predetermined time T2 (for example, 10 minutes), and makes the hot water from the second air outlet 31b in a lump shape. It is determined whether or not the time to blow out is equal to or longer than a third predetermined time T3 (for example, 5 minutes).

  When receiving the operation signal from the determination unit 61, the blower mechanism control unit 62 drives the blower mechanism 2 to suck air or the like containing oil generated by cooking from the intake port 1a and discharge it from the exhaust port 1b. . The blower mechanism control unit 62 stops the blower mechanism 2 when receiving a stop signal from the determination unit 61.

  When receiving a cleaning command from the determination unit 61, the cleaning control unit 63 opens the first on-off valve 3 a and blows mist or hot water from the nozzle 31 toward the inner surface 40 of the rectifying plate 4. At this time, the second opening / closing valve 32b may also be opened, and hot water may be blown out from the third blower outlet 32a toward the inside of the blower mechanism 2. The cleaning control unit 63 always opens the first on-off valve 3a when receiving a cleaning command from the determination unit 61, and the second on-off valve 32b opens every time a plurality of cleaning commands are issued. You may comprise as follows.

  When the notification unit 64 receives the determination result that the total operation time of the blower mechanism 2 is equal to or longer than the first predetermined time T1 from the determination unit 61, the notification unit 64 notifies the user that the cleaning time has come. As a notification form, for example, the washing button 53 is blinked, a sound is notified, or a separately provided light emitting unit (for example, an LED light) is turned on. As a result, the user can be prompted to press the cleaning button 53. The notification unit 64 lights the operation button 51 when the air blowing mechanism 2 is being driven, and lights the washing button 53 when the range hood X is being washed.

  Then, an example of the washing | cleaning method of the baffle plate 4 which concerns on this embodiment is demonstrated using FIG.

  When the power is turned on and the user presses the operation button 51, the operation of the blower mechanism 2 starts (# 71). Next, the determination unit 61 determines whether or not the user has pressed the stop button 52 to input a stop command for the blower mechanism 2 (# 72). When the stop command for the blower mechanism 2 is not input (# 72 No determination), the operation of the blower mechanism 2 is continued. On the other hand, when the stop command for the blower mechanism 2 is input (# 72 Yes determination), the determination unit 61 determines whether the total operation time of the blower mechanism 2 is equal to or longer than the first predetermined time T1 (# 73). When the total operation time of the blower mechanism 2 is equal to or longer than the first predetermined time T1 (# 73 Yes determination), the notification unit 64 notifies the user that the cleaning time has come (# 74).

  Next, when the user presses the cleaning button 53 and receives a cleaning command (# 75 Yes determination), the determination unit 61 transmits the cleaning command for the current plate 4 to the cleaning control unit 63. Upon receiving the cleaning command, the cleaning control unit 63 opens the first on-off valve 3a to eject mist from the first outlet 31a of the nozzle 31 toward the inner surface 40 of the rectifying plate 4 (# 76). ). As a result, the oil adhering to the inner surface 40 of the current plate 4 is softened and floated. When the time for ejecting mist from the first air outlet 31a is the second predetermined time T2 (# 77 Yes determination), the second air outlet 31b is switched to blow out hot water in a lump (# 78). As a result, the oil component floating in the mist is forcibly washed away with massive hot water and drained from a drain port 41 provided at one end of the rectifying plate 4.

  Next, when the time for warm water to be blown out from the second outlet 31b is equal to or longer than the third predetermined time T3 (Yes in # 79), the cleaning is stopped (# 80) and the cleaning process is terminated. At this time, the notification unit 64 turns off the cleaning button 53 and notifies the user of the end of cleaning by sound or turning off the light emitting unit. Thus, since the washing | cleaning of the baffle plate 4 is started after stopping the ventilation mechanism 2, the problem that mist is forcedly discharged | emitted by the ventilation mechanism 2 can be prevented.

  In the present embodiment, since the nozzle 31 is configured to blow warm water toward the inner surface 40 of the rectifying plate 4, the oil component adhering to the inner surface 40 of the rectifying plate 4 can be forcibly washed. And since the drain port 41 is provided in the baffle plate 4, it becomes possible to discharge | emit the hot water in which the oil component was mixed each time, and the baffle plate 4 can be made into a clean state.

  In the present embodiment, since the inclined surface is provided so that the drainage port 41 of the rectifying plate 4 is lower than the position directly below the nozzle 31, the hot water that has collided with the inner surface 40 of the rectifying plate 4 smoothly flows along the inclined surface. It flows and is discharged from the drain port 41. As a result, there is no inconvenience that water containing oil does not remain on the inner surface 40 of the rectifying plate 4 and that the remaining water evaporates and the oil reattaches to the inner surface 40 of the rectifying plate 4. Moreover, since the drain port 41 is provided on one end side of the rectifying plate 4 and the nozzle 31 is provided immediately above the other end side of the rectifying plate 4, hot water can be spread over the entire area of the inner surface 40 of the rectifying plate 4. .

  In this embodiment, since the nozzle 31 is formed so that mist and massive hot water can be blown out, the oil attached to the rectifying plate 4 is softened and floated by the mist, and then the oil is forcibly removed with massive hot water. It can be washed away. As a result, the cleaning efficiency of the current plate 4 can be increased.
