Description

  The present invention relates to a range hood.

Such a range hood will be used to discharge cooking exhaust discharged from a pan heated by a heating cooker such as a gas stove or IH cooker, and is generally installed in a kitchen. It will be provided near the ceiling of the kitchen as the upper part of the cooking device.
That is, the range hood is configured in such a manner that a range hood body provided with an exhaust passage communicating the exhaust inlet and the exhaust outlet and an exhaust fan that ventilates the exhaust passage is provided. The hood body will be provided near the kitchen ceiling.

  By the way, during cooking using a heating cooker, cooking exhaust is discharged to the outside, but odor remains in the indoor space where the kitchen is installed even after cooking is finished. Become. If the exhaust fan is continuously operated in order to eliminate such odor, inconveniences such as exhausting air in the air-conditioned room will occur.

Therefore, it is conceivable to provide the range hood with a function of circulating indoor air in such a form that the air sucked from the room is deodorized through a deodorizing filter and the deodorized air is returned to the room.
As such a range hood, an air outlet that blows air into the room, a return passage that branches from the middle of the exhaust passage, and that guides the air flowing through the exhaust passage to the air outlet, and flows through the exhaust passage A passage switching unit (damper) is provided to switch between an exhaust state in which the air to be flowed directly toward the exhaust outlet and a circulating state in which the air that flows through the exhaust passage flows toward the air outlet through the return passage In addition, there is one in which a deodorizing filter is provided in the return passage (see, for example, Patent Document 1 (paragraph [0028], FIG. 12)).

  That is, in the range hood of Patent Document 1, the air sucked by the exhaust fan from the exhaust suction port is discharged in the exhaust state by flowing the exhaust passage to the outside through the exhaust passage, and in the circulating state. Is configured to flow through the exhaust passage and the return passage and deodorize with a deodorizing filter, and then blow out into the room from the air outlet.

  Moreover, in the range hood of patent document 1, the deodorizing filter is comprised in the washing type which recovers deodorizing performance by washing with water, and the exit for attaching / detaching a deodorizing filter is formed in the return path | route. And providing a door for opening and closing the outlet.

Japanese Patent No. 3780050

  In the conventional range hood, there is a disadvantage that even if it is deodorized with a deodorizing filter in a circulating state, there is a disadvantage that odorous components are likely to remain, and there is a disadvantage that the deodorizing performance of the deodorizing filter is likely to deteriorate early, and an improvement is desired.

That is, in the conventional range hood, in the circulating state, air is sucked in by the exhaust fan from the exhaust suction port, and the sucked air flows through a part of the exhaust passage. Therefore, the air deodorized by the deodorizing filter However, since the odor component adhering to the exhaust fan or the exhaust passage is included, the air deodorized by the deodorization filter tends to include a large amount of odor component.
As a result, even if the deodorizing filter is deodorized, the odorous component tends to remain, and the deodorizing performance of the deodorizing filter tends to deteriorate early.

  Moreover, in the conventional range hood, if the deodorizing performance of the deodorizing filter decreases, the deodorizing filter is recovered by removing the deodorizing filter from the return passage and washing it with water. There is an inconvenience that the regeneration of the filter is a troublesome work that takes time.

  The present invention has been made in view of the above circumstances, and its purpose is that the deodorizing function of the deodorizing filter is quickly reduced in a circulating state in which indoor air is deodorized by the deodorizing filter and returned to the room. The object is to provide a range hood that can satisfactorily perform deodorization of air and can regenerate the deodorization filter without requiring special labor.

The range hood of the present invention includes an exhaust passage communicating the exhaust inlet and the exhaust outlet, and an exhaust fan that ventilates the exhaust passage.
A circulation passage that connects the circulation inlet and the circulation outlet that blows air sucked from the circulation inlet into the room, a circulation fan that acts to ventilate the circulation passage, and a flow in the circulation passage A deodorizing filter that deodorizes air,
A regeneration processing unit for regenerating the deodorizing filter is provided in the circulation passage,
The operation control unit is configured to execute a regeneration process for operating the regeneration processing unit every time the regeneration start condition is satisfied.

That is, in a circulating state in which room air is deodorized by the deodorizing filter and returned to the room, the air sucked from the circulation inlet by the circulation fan is caused to flow through the circulation passage and blown out from the circulation outlet to the room. It will be.
And the odor component is removed from the air which flows through a circulation channel | path by a deodorizing filter, and it blows off indoors from the suction inlet for circulation after that.

  Therefore, in the circulating state where the indoor air is deodorized by the deodorizing filter and returned to the room, the circulating air flows through the circulation passage formed as a passage different from the exhaust passage. The deodorized air does not contain odorous components adhering to the exhaust fan or the exhaust passage, so the deodorizing performance of the deodorizing filter is prevented from deteriorating early, and the air is deodorized well. It can be carried out.

  In addition, a regeneration processing unit that regenerates the deodorizing filter is provided in the circulation passage, and the operation control unit performs a regeneration process that activates the regeneration processing unit every time the regeneration start condition is satisfied. Since the filter is automatically regenerated, the deodorizing filter can be regenerated without any special effort.

  In short, according to the characteristic configuration of the range hood of the present invention, in a circulating state in which indoor air is deodorized by the deodorizing filter and returned to the room, the deodorizing performance of the deodorizing filter is suppressed from deteriorating early, but the air The deodorizing filter can be regenerated without any special effort.

  A further characteristic configuration of the range hood of the present invention is configured such that the operation control unit determines that the regeneration start condition is satisfied each time the integrated operation amount of the circulation fan reaches a set operation amount. There is in point.

  That is, every time the cumulative operation amount of the circulation fan reaches the set operation amount, the regeneration process for operating the regeneration processing unit is executed assuming that the regeneration start condition is satisfied. When the amount reaches the set operation amount, or when the accumulated operation amount after finishing the regeneration process reaches the set operation amount, the regeneration process is executed assuming that the regeneration start condition is satisfied. The deodorizing filter can be regenerated at an appropriate timing when the deodorizing filter needs to be regenerated.

  In other words, the relationship between the cumulative operating amount of the circulation fan and the deodorizing performance of the deodorizing filter is such that the deodorizing performance of the deodorizing filter decreases as the cumulative operating amount of the circulating fan increases. Since the accumulated operating amount of the circulation fan is an index indicating a decrease in the deodorizing performance of the deodorizing filter, it is possible to obtain an appropriate timing at which the deodorizing filter needs to be regenerated with the accumulated operating amount of the circulating fan. Therefore, the deodorizing filter can be regenerated at an appropriate timing.

  In short, according to the further characteristic configuration of the range hood of the present invention, the deodorizing filter can be regenerated at an appropriate timing.

  A further characteristic configuration of the range hood of the present invention is that the integrated operation amount reaches an operation amount for periodic regeneration that is smaller than the set operation amount each time the operation control unit reaches a preset regeneration processing time. In other words, when the integrated operation amount reaches the periodic regeneration operation amount, it is determined that the regeneration start condition is satisfied.

  That is, the regeneration processing time for operating the regeneration processing unit to perform the regeneration processing is set to a time when it is rarely required to deodorize indoor air with the deodorizing filter, for example, at night, and the regeneration processing time is set. By performing the regeneration process at, the room air is often used in the deodorizing filter for the regeneration process, for example, in the daytime when it is often required to deodorize the room air with the deodorizing filter. It is possible to avoid being unable to deodorize.

  Then, at the regeneration processing time, it is determined whether or not the accumulated operation amount of the circulation fan has reached a regular regeneration operation amount that is smaller than the set operation amount, and the accumulated operation amount has reached the regular regeneration operation amount. If the playback start condition is satisfied, the playback process is executed. Therefore, it is possible to appropriately perform the playback process at the playback process time while suppressing unnecessary playback process. it can.

  In other words, when the regeneration process time is reached, if the regeneration process is always executed regardless of the accumulated operation amount of the circulation fan, the accumulation operation amount of the circulation fan is small and it is not necessary to perform the regeneration process. Although the regeneration process is wasteful, the regeneration process is performed only when the integrated operation amount reaches the periodic regeneration operation amount. Therefore, the regeneration process is performed when it is not necessary. Waste can be avoided.

  In addition, at the regeneration processing time, if the integrated operation amount reaches the periodic regeneration operation amount that is smaller than the set operation amount, the regeneration process is performed. Therefore, the integrated operation amount does not reach the set operation amount. In the time zone where it is often required to deodorize indoor air with a deodorizing filter, the indoor air cannot be deodorized with the deodorizing filter for the regeneration process. By avoiding this, the indoor air can be appropriately deodorized.

  In short, according to the further characteristic configuration of the range hood of the present invention, it is possible to appropriately deodorize indoor air in a time zone in which indoor air is often required to be deodorized with a deodorizing filter.

  A further characteristic configuration of the range hood of the present invention is that the operation control unit is configured to operate the exhaust fan when executing the regeneration process.

  That is, when the regeneration process of the deodorizing filter is executed, an odor is generated by the regeneration process. However, when the regeneration process is performed, it is generated during the regeneration process of the deodorizing filter by operating the exhaust fan. Odor is discharged to the outside.

  In this way, even if odor is generated during the regeneration process of the deodorizing filter, the generated odor is appropriately discharged to the outside, so that the odor generated during the regeneration process of the deodorizing filter flows into the room, It is possible to prevent the user from feeling uncomfortable by suppressing the stay.

  In short, according to the further characteristic configuration of the range hood of the present invention, it is possible to suppress the odor generated during the regeneration process of the deodorizing filter from flowing into and staying in the room.

  A further characteristic configuration of the range hood of the present invention is that the operation control unit is configured to continuously operate the exhaust fan for a set duration after the regeneration process is completed. is there.

  That is, even after the regeneration processing of the deodorizing filter is completed, the exhaust fan is continuously operated for the set duration time, so that it is appropriate that the odor generated by the regeneration processing remains in the room. Can be suppressed.

  In short, according to the further characteristic configuration of the range hood of the present invention, it is possible to appropriately suppress the odor generated by the regeneration process from remaining in the room.

  According to a further characteristic configuration of the range hood of the present invention, when the operation control unit continuously operates the exhaust fan for the set duration time, the air volume of the exhaust fan is changed to the regeneration process. It is in the point which is comprised so that it may adjust to the air volume for post-processing smaller than the air volume at the time of performing.

  That is, when the exhaust fan is continuously operated for a set duration after the regeneration process of the deodorizing filter is completed, the air volume of the exhaust fan is larger than the air volume when the regeneration process is being performed. It will be adjusted to a small aftertreatment air volume.

  Thus, after the regeneration process of the deodorizing filter is completed, when the exhaust fan is continuously operated over the set duration time, by adjusting the air volume of the exhaust fan to the post-process air volume, While the exhaust fan is continuously operated, it is possible to prevent the air conditioning in the room from being damaged as much as possible.

  In short, according to the further characteristic configuration of the range hood of the present invention, it is possible to suppress the air conditioning in the room from being damaged as much as possible while continuously operating the exhaust fan.

A further characteristic configuration of the range hood of the present invention includes the circulation passage in a form in which a pair of circulation passage portions each including the deodorizing filter and the regeneration processing unit are independent passages,
A circulation path selection unit is provided for selecting which of the pair of circulation path portions allows the air introduced from the circulation inlet to flow.

  That is, since the circulation path selection unit can select which of the pair of circulation path parts each having the deodorizing filter and the regeneration processing unit to flow the air introduced from the circulation inlet, the pair of circulations Even in a state where the deodorizing filter on one side of the path portion is being regenerated, the air introduced from the circulation suction port flows through the circulation path portion on the other side, thereby deodorizing the indoor air. It is possible to continue to perform well.

  In other words, regenerating the deodorizing filter by regenerating the deodorizing filter in the circulation path portion that does not flow the air while selecting one of the pair of circulation path portions and flowing the air introduced from the circulation suction port. While performing properly, even during regeneration of the deodorizing filter, the indoor air can be deodorized continuously.

  In short, according to the further characteristic configuration of the range hood of the present invention, the indoor air can be deodorized continuously and well even during regeneration of the deodorizing filter.

(Control configuration)
As shown in FIG. 4, a hood control unit A is provided as an operation control unit that controls the operation of the range hood 2 based on a command from the operation unit S. The hood control unit A and the stove control unit B of the gas stove GC Are connected so as to be able to communicate wirelessly.
That is, the hood side communication unit As included in the hood control unit A and the stove side communication unit Cs included in the stove control unit B are connected to each other via a WiFi router R (hereinafter abbreviated as “router”).

  When either the stove burner or grill burner provided in the gas stove GC is used, the stove control unit B communicates information indicating that cooking is in progress to the hood control unit A, and all of the stove burner and grill burner When the operation is stopped, information indicating that the cooking is finished is communicated to the hood control unit A.

The exhaust passage H is provided with an exhaust odor sensor 8 as an odor sensor for detecting the concentration of odor components contained in the exhaust, and a temperature sensor 9 for detecting the temperature of the exhaust passage H. These exhaust odor sensors 8 The detection information of the temperature sensor 9 is input to the hood control unit A.

(Manual operation mode)
In the manual operation mode, when the operation of the exhaust fan Ef is commanded, the hood control unit A operates the exhaust fan Ef with the circulation fan Df stopped, and operates the circulation fan Df. Is commanded, the circulation fan Df is operated with the exhaust fan Ef stopped.

That is, when the operation is commanded by the exhaust operation switch, the exhaust fan Ef starts to be operated, and when the circulation fan Df is operated at that time, the circulation fan Df is stopped. become.
When the operation is commanded by the circulation operation switch, the operation of the circulation fan Df is started. When the exhaust fan Ef is operated at that time, the exhaust fan Ef is stopped. become.

  Even when the automatic operation mode is set by the operation mode switch, when the exhaust fan Ef or the circulation fan Df is not operated, the exhaust operation switch or the circulation operation switch can be used for exhaust. The fan Ef and the circulation fan Df can be operated in a timely manner.

(Automatic operation mode)
The hood control unit A starts the operation of the exhaust fan Ef when the cooking of the gas stove GC is started, and when the exhaust operation continuation time has elapsed after the completion of the cooking, the operation of the exhaust fan Ef is started. It is configured to stop, and after the operation of the exhaust fan Ef is stopped, the circulation fan Df is operated until the set circulation operation time elapses.

In addition, the hood control unit A performs a display process for displaying the remaining operation time on the display unit U by subtracting the elapsed time after the end of cooking from the time obtained by adding the exhaust operation duration time and the set circulation operation time. It is configured as follows.
Therefore, after the end of the cooking, the exhaust fan Ef and the circulation fan Df are sequentially operated, but the operations of the exhaust fan Ef and the circulation fan Df that are sequentially operated in this way are stopped. The remaining time until the vehicle is displayed on the display unit U as the remaining operation time.

(About operation time calculation processing)
The hood control unit A determines the exhaust operation duration, the operation duration of the gas stove GC, the detection information (odor sensor value) of the exhaust-side odor sensor 8 at the end of heating cooking, and the temperature sensor detection at the end of heating cooking The exhaust operation continuation time is set based on the information (temperature sensor value).

  In other words, the longer the operation duration of the gas stove GC is, the longer the exhaust operation duration is. The lower the detection information (odor sensor value) of the exhaust-side odor sensor 8 at the end of cooking is, the longer the exhaust operation duration is. Further, the exhaust operation continuation time is set in such a manner that the exhaust operation continuation time is lengthened as the temperature sensor detection information (temperature sensor value) at the end of cooking is higher.

The hood control unit A is configured to set the set circulation operation time longer as the exhaust operation duration time is longer.
Specifically, in the present embodiment, a time obtained by multiplying the exhaust operation continuation time by 1.5 is set as the set circulation operation time.

(About playback processing)
Each time the regeneration start condition is satisfied, the hood control unit A operates the regeneration heater Qh for a preset regeneration processing time (for example, 30 minutes) to execute a regeneration process for regenerating the deodorizing filter Q. It is configured.
In the present embodiment, it is determined that the regeneration start condition is satisfied every time the accumulated operation amount of the circulation fan Df after the regeneration processing reaches the set operation amount, and the regeneration processing is automatically executed. It is configured.

  In other words, when the regeneration process is executed, when the integrated operation amount after the regeneration process reaches the set operation amount, it is determined that the regeneration start condition is satisfied. When the integrated operation amount after installation reaches the set operation amount, it is determined that the regeneration start condition is satisfied.

In the present embodiment, the circulation passage J is provided with a flow rate sensor 11 that detects the flow rate of the flowing air.
And the hood control part A calculates | requires the integrated flow which integrated | accumulated the detected flow of this flow sensor 11 as an integrated operation amount, and when this integrated flow becomes more than the set integration flow W as a setting operation amount, deodorizing filter Q Is configured to regenerate.

  By the way, the regeneration start condition is satisfied during the operation of the circulation fan Df. In this embodiment, when the regeneration start condition is satisfied, the operation of the circulation fan Df is immediately stopped to perform the regeneration process. However, for example, the reproduction process may be executed after a set delay time (for example, about 15) has elapsed.

  Further, every time the hood control unit A reaches a preset regeneration processing time (for example, 1:00 am), the integrated flow rate (integrated operation amount) is smaller than the set integrated flow rate W (set operation amount) for periodic regeneration. It is determined whether or not the flow rate V (corresponding to the operation amount for periodic regeneration) has been reached, and regeneration starts when the integrated flow rate (integrated operation amount) reaches the periodic regeneration flow rate V (operation amount for periodic regeneration). It is configured to determine that the condition is satisfied.

The reproduction processing time (for example, 1:00 am) is set to a time at which the circulation fan Df is predicted not to operate, but the reproduction start condition at the reproduction processing time (for example, 1:00 am) If the circulation fan Df is in operation when it is determined that the condition is satisfied, the operation of the circulation fan Df is immediately stopped and the regeneration process is executed.
The operation unit S is provided with a time setting unit for setting the reproduction processing time.

  Further, the hood control unit A is configured to operate the exhaust fan Ef when executing the regeneration process, and after the regeneration process is completed, the exhaust fan Ef is set to a set duration (for example, 15 minutes). In this case, for example, the reproduction process may be executed after a set delay time (for example, about 15) has elapsed. .

  When the hood control unit A operates the exhaust fan Ef continuously for a set duration (for example, 15 minutes), the air volume of the exhaust fan Ef is being regenerated. It is comprised so that it may adjust to the post-processing air volume smaller than an air volume.

  In other words, in the present embodiment, when the regeneration process is being performed, the exhaust fan Ef is operated with an intermediate air volume, and the exhaust fan Ef is continued for a set duration (for example, 15 minutes). When operating, the air volume of the exhaust fan Ef is set to a weak air volume as a post-processing air volume.

(Details of playback processing)
Next, the reproduction process will be described based on the flowchart of FIG.
First, it is determined whether or not the regeneration control in which either the regeneration process or the process of operating the exhaust fan Ef after the regeneration process is being performed (# 1). If it is determined that the regeneration control is not being performed, It is determined whether or not the integrated flow rate is greater than or equal to the set integrated flow rate W (# 2).
The integrated flow rate is reset every time the regeneration process is executed, and is obtained as an integrated flow rate after the regeneration process is completed.

  When it is determined that the integrated flow rate is equal to or higher than the set integrated flow rate W, the regeneration heater Qh is activated to start the regeneration process (# 5). When starting the regeneration process, the exhaust fan Ef is started to operate at an intermediate air volume, and the operation of the circulation fan Df is stopped.

  If it is determined at # 2 that the integrated flow rate is not equal to or greater than the set integrated flow rate W, it is determined whether or not it is a preset regeneration process time (for example, 1 am) (# 3), and the regeneration process time is determined. If it is determined (for example, 1:00 am), it is subsequently determined whether or not the integrated flow rate is equal to or higher than the periodic regeneration flow rate V (# 4).

  If it is determined in # 4 that the integrated flow is equal to or higher than the periodic regeneration flow V, the process of # 5 is executed. That is, the regeneration heater Qh is actuated to start the regeneration process, the exhaust fan Ef is actuated with an intermediate air volume, and the circulation fan Df is deactivated.

  In step # 3, if it is determined that it is not the regeneration processing time (for example, 1:00 am), and if it is determined that the integrated flow rate is not equal to or greater than the periodic regeneration flow rate V, the process proceeds to processing other than the regeneration management process. become.

  After executing the process of # 5, it is determined whether or not the playback processing time (for example, 30 minutes) has elapsed (# 7), and when the playback processing time (for example, 30 minutes) has elapsed, The regeneration process is stopped by stopping the operation of the heater Qh (# 8). When stopping the regeneration process, the air volume of the exhaust fan Ef is continued in a state where the air volume of the exhaust fan Ef is changed to a weak air volume.

After executing the process of # 8, it is determined whether or not a set duration (for example, 15 minutes) for continuing the operation of the exhaust fan Ef has passed (# 9), and a set duration (for example, 15 minutes). ) Has stopped, the operation of the exhaust fan Ef is stopped (# 10), and thereafter, the process proceeds to a process other than the regeneration management process.
If it is determined in # 9 that the set duration (for example, 15 minutes) has not elapsed, the process proceeds to a process other than the reproduction management process.

  If it is determined in step # 1 that playback control is in progress, it is subsequently determined whether playback processing is in progress (# 6). If it is determined that playback processing is in progress, # 7 is determined. It is determined whether or not the reproduction processing time (for example, 30 minutes) has elapsed, and if it is determined that the reproduction processing is not in progress, the process proceeds to # 9 and the set duration time. It is determined whether (for example, 15 minutes) has elapsed.

[Second Embodiment]
Next, a second embodiment will be described. This second embodiment differs from the first embodiment in the installation configuration of the deodorizing filter Q and the regeneration heater Qh, and accordingly, the configuration of the circulation passage J is different. However, since the other configuration is the same as that of the first embodiment, only the configuration different from that of the first embodiment will be described in the following description.

In the second embodiment, as shown in FIG. 6, the circulation passage J is provided with a pair of circulation passage portions Jb each having a deodorizing filter Q and a regeneration heater Qh as independent passages.
