Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ventilation system in which a bathroom dryer and a range hood are interlocked, and in particular, realizes proper ventilation by linking the continuous ventilation function of the range hood to the constant ventilation function of the bathroom dryer and cleaning the range hood. The present invention relates to a ventilation system that can appropriately notify the maintenance time.
[0002]
[Prior art]
A range hood installed in a general household kitchen is generally not operated to operate in conjunction with other ventilation devices by performing ventilation operation with simple operation buttons. In addition, there is no function for notifying the maintenance time such as cleaning of the range hood, and the user usually performs maintenance regularly or irregularly. Therefore, in a user's house that does not perform maintenance frequently, the maintenance time of the range hood is overdue, causing a failure and shortening the service life. Accordingly, it is desirable to provide a function for integrating the operating time of the range hood so as to notify the maintenance time.
[0003]
As an example, a device for forcing a user to clean dust accumulated in a filter of a clothes dryer to prevent a failure or shortening of life has been proposed (for example, Patent Document 1). Such a clothes dryer counts the number of operations and the operation time, stops the operation when the preset number of times and time is reached, and stops the operation again until the filter cleaning is executed. However, realizing such a function with a single range hood is not preferable because it leads to an increase in cost.
[0004]
On the other hand, the Building Standards Law has been revised since July 2003, and in highly airtight houses to be built in the future, in order to discharge volatile organic compounds such as formaldehyde that are harmful to the human body generated from furniture, etc., 24 hours a day It is obliged to install ventilation equipment that secures the ventilation frequency of 0.5 times (the air in the house is changed by half every hour).
[0005]
Therefore, it is expected that the 24-hour ventilation function (generally the constant ventilation function) installed in the bathroom heater / dryer installed in the bathrooms of many highly airtight houses is used as the ventilation equipment.
[0006]

JP-A-5-15698 [0007]
[Problems to be solved by the invention]
However, with the ventilation capacity of the regular ventilation function that is installed in the generally popular bathroom heater / dryer, the above-mentioned ventilation frequency of 0.5 times can be realized in a house of a certain size. In a large house with a residential area exceeding about 90 square meters, it is difficult to realize the above ventilation frequency with the ventilation capacity of the regular ventilation function of the bathroom heater / dryer.
[0008]
Then, the objective of this invention is providing the ventilation system which can observe a building standard law in a high airtight house.
[0009]
Furthermore, the objective of this invention is providing the ventilation system which can notify automatically the maintenance time of a range hood.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, one aspect of the present invention is a ventilation system in which a hot water supply central system having a bathroom dryer installed in a bathroom and a range hood are connected via a communication medium.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. However, the protection scope of the present invention is not limited to the following embodiments, but extends to the invention described in the claims and equivalents thereof.
[0013]
FIG. 1 is a diagram illustrating a configuration example of a ventilation system according to the present embodiment. A hot water supply central system 1 having a heat source device 10 having a hot water supply function has a bathtub 13, an air conditioning air conditioner 12, a floor heating 14, a bathroom heating dryer 16, and the like as hot water supply terminals. Hot water is supplied through the hot water supply pipe indicated by. The control microprocessor mp built in the heat source device 10 is connected to the main remote controller 11 via a wired or wireless communication medium 20 and executes hot water supply control in response to various operation commands from the main remote controller 1. The control microprocessor mp of the heat source device 10 is connected to the air conditioning air conditioner 12, the floor heating 14, and the bathroom heating dryer 16 via another wired or wireless communication medium 22, and corresponding signals for operation control. Send and receive.
[0014]
The control microprocessor mp of the heat source machine issues an operation command to each terminal, accumulates the operation time, and gives a notification for prompting maintenance at an appropriate time on the display unit of the main remote controller 11.
[0015]
The bathroom heating dryer 16 is connected to a dryer remote controller 17 installed in the bathroom or its dressing room via a communication medium 24, and responds to an operation command from the dryer remote controller 17 to respond to the heating and drying operation. I do.
[0016]
The range hood 18 installed in the kitchen is provided with an operation panel 19 on the main body, and is connected to the remote controller 17 of the bathroom heater / dryer 16 via a wired or wireless communication medium 26. The ventilation system of the present embodiment includes a bathroom heater / dryer 16 and a range hood 18 in the hot water supply central system 1, and both are connected via a communication medium 26.
[0017]
The bathroom heater / dryer 16 has a hot air ventilation function for supplying hot air into the bathroom and a bathroom ventilation function for ventilating the bathroom, and both functions ventilate the bathroom with a sufficient amount of ventilation. However, the warm air ventilation function and the bathroom ventilation function have high noise values, and it is not preferable to control the hot air ventilation function and the on state continuously for a long time. The bathroom dryer 16 has a constant ventilation function that automatically operates when the power is turned on. The constant ventilation function is a function that has less ventilation than the warm air ventilation function and the bathroom ventilation function, but has a low noise level and is suitable for continuous operation, and is a function that continues minute ventilation for 24 hours. This constant ventilation function can be controlled to be in an off state by performing a special operation on the dryer remote controller 17, for example, but in a normal state, the operation is controlled in response to power on. Further, as will be described later, the remote controller 17 of the bathroom heater / dryer 16 is provided with a control button for temporarily stopping the continuous ventilation function during bathing or the like.
[0018]
An operation command for the bathroom heater / dryer is given from the remote controller 17, but in response to the operation command, a hot water supply request is issued to the control microprocessor mp of the heat source device, and hot water ventilation operation is provided by the hot water supply. The operating status of the bathroom heater / dryer 16 is transmitted to the control microprocessor mp of the heat source device via the communication line 22.
[0019]
The range hood 18 is the same as a range hood that is generally popular in appearance, and an operation panel attached to the main body has one or more types of forced ventilation buttons, and the forced ventilation buttons are on-controlled. Therefore, it is possible to forcibly ventilate. The ventilation amount in the forced ventilation mode has a sufficient amount for exhausting the exhaust gas in the range, but its noise value is high and is not suitable for continuous operation for a long time. The range hood 18 of the present embodiment has a constant ventilation function in addition to the forced ventilation function described above. This continuous ventilation function is a function of continuously ventilating with a small amount of ventilation as in the case of the bathroom heating dryer 16, and is linked to being powered on by the remote controller 17 of the bathroom heating dryer 16. Therefore, it is not necessary for the user to perform a control operation from the operation panel 19.
[0020]
The ventilation system of the present embodiment also has a constant ventilation function of the range hood 18 in conjunction with the constant ventilation function of the bathroom heater / dryer 16 so that sufficient ventilation can be ensured even in a large house. Controlled on. These continuous ventilation functions are suitable for 24-hour continuous ventilation because the noise level is low although the individual ventilation amount is small. In addition, when various functions of the bathroom heater / dryer 16 are operated and a sufficient ventilation amount can be ensured, the continuous ventilation function of the range hood 18 is controlled to be off in order to prevent excessive ventilation. . Conversely, even when forced ventilation control is performed on the range hood 18 side, the constant ventilation function of the bathroom heater / dryer 16 is controlled to be off in order to prevent excessive ventilation.
[0021]
In order to link the continuous ventilation function in this way, in the ventilation system, the remote controller 17 of the bathroom heating dryer 24 and the range hood 18 are connected via a communication medium 26. Accordingly, the control microprocessor mp of the heat source device 10 has a function of monitoring the operation state of the range hood 18 via the dryer remote controller 17 and can integrate the operation time of the range hood 18. . Therefore, the control microprocessor mp uses this monitoring function to detect the maintenance time of the range hood 18 and displays on the dryer remote controller 17 of the bathroom heating dryer 16 that the maintenance time has been reached. To perform predetermined maintenance such as cleaning of the range hood 18. Furthermore, the control microprocessor mp also accumulates the operation time of the bathroom heater / dryer 16 itself and reports the maintenance time. By notifying the maintenance time, it is possible to prevent the malfunction of the ventilation function at all times, and to stop the discharge of harmful substances such as volatile organic compounds and prevent harm to the health of residents.
[0022]
FIG. 2 is an operation chart of the ventilation system. In the figure, the vertical direction corresponds to time. Hereinafter, the interlocking control of the regular ventilation function which each bathroom heating dryer 16 and the range hood 18 which comprise a ventilation system have is demonstrated.
[0023]
When the bathroom heater / dryer 16 is turned on, the normal ventilation operation is automatically turned on to enter the normal ventilation mode (S10). When the operation is turned on, a linked operation command for the continuous ventilation function of the range hood is sent, and the continuous ventilation operation of the range hood 18 is also turned on to enter the continuous ventilation mode. A state where the constant ventilation mode of both the bathroom heater / dryer 16 and the range hood 18 is on-controlled is the steady state of the ventilation system.
[0024]
When forced ventilation is controlled to be turned on from the operation panel of the range hood 18 for reasons such as cooking in the kitchen (S12), the continuous ventilation mode is temporarily turned off in the range hood, and the change in the state changes accordingly in the bathroom. This is notified to the heating dryer 16 side. The amount of forced ventilation is greater than that in the regular ventilation mode, and sufficient ventilation is secured for residential ventilation. In response to the notification, the regular ventilation mode of the bathroom heating dryer 16 is automatically set. Controlled off. When the forced ventilation mode in the range hood is turned off (S14), the normal ventilation mode is restored, and the change in the state is transmitted to the bathroom heating dryer 16, and the normal ventilation function is automatically turned on. Then, both the range hood and the bathroom heater / dryer return to the steady state in which the ventilation mode is always set.
[0025]
Next, on the bathroom heater / dryer 16 side, when the bathroom ventilation or the warm air ventilation mode is controlled to be on (S16), the constant ventilation mode is temporarily controlled to be off, and the state change is notified to the range hood 18. In response to this, the range hood 18 temporarily turns off the continuous ventilation mode. Sufficient ventilation is obtained in the bathroom ventilation and hot air ventilation modes, so it is possible to prevent excessive outside air from entering the room by ventilating more than necessary by temporarily turning off the regular ventilation mode temporarily. Can do. When the bathroom ventilation or warm air ventilation mode of the bathroom heater / dryer 16 is controlled to be off (S18), the normal ventilation mode is restored. Then, the state change is transmitted to the range hood side, and the range hood side also turns on the constant ventilation mode and returns to the steady state.
[0026]
Next, when bathing or the like, when the control button “bathing” for temporarily turning off the constant ventilation mode is pressed (S20), the constant ventilation mode on the bathroom heating dryer side is automatically turned off. And this state change is transmitted to the range hood side. The range hood side is preferably controlled to increase the ventilation amount while continuing the ventilation mode at all times. Thereby, sufficient ventilation with respect to a residence can be ensured. When the “bathing” button is turned off (S22), the constant ventilation mode of the bathroom heater / dryer is automatically turned on, the state change is transmitted to the range hood side, and the normal ventilation mode on the range hood side is normally set. The ventilation system is returned to the steady state. This “bathing” button can also be used to temporarily turn off the operation of the bathroom heating dryer 16.
[0027]
Conversely, in the range hood 18, the power can be turned off for reasons such as cleaning the filter, and in such a case, the constant ventilation mode is turned off (S24). This state change is transmitted to the bathroom heating / drying machine 16 side, and accordingly, the ventilation amount of the bathroom heating / drying machine 16 is preferably increased. When the operation of the range hood 18 is on-controlled (S24), the normal ventilation mode is restored, and the state change is transmitted to the bathroom heating dryer 16 side. In response to this, the ventilation amount in the constant ventilation mode is returned to the normal amount in the bathroom heating dryer 16.
[0028]
Finally, when the power supply of the bathroom heater / dryer 16 is turned off due to reasons such as absence for a long period of time (S28), the normal ventilation mode is also stopped, and the normal ventilation mode on the range hood side is also controlled to be off accordingly. The As a result, both constant ventilation modes are turned off.
[0029]
As described above, the constant ventilation functions of the bathroom heater / dryer 16 and the range hood 18 are linked to each other, and an appropriate ventilation amount is secured. Along with this interlocking operation, the control microprocessor mp of the heat source device 10 constantly monitors the operation status of the range hood via the remote controller 17 of the bathroom heating dryer 16, and integrates the operation time. Whenever the time required for maintenance is reached, a maintenance display is displayed on the dryer remote controller 17 to prompt the user to perform maintenance such as cleaning the range hood.
[0030]
In the above example, the operating status of the range hood is monitored by the control microprocessor mp via the remote controller 17 of the bathroom heater / dryer, the operating time is integrated, and the maintenance notification is displayed. Alternatively, the dryer remote controller 17 may perform operation time integration and maintenance notification. Alternatively, the dryer remote controller 17 may periodically notify the control microprocessor mp, which accumulates the operation time of the range hood.
[0031]
That is, one of the control means in the hot water supply central system 1 with high intelligence monitors the operation status of the range hood, counts the accumulated operation time, and notifies an appropriate maintenance timing of the range hood. Therefore, it is possible to secure a sufficient constant ventilation amount while minimizing the cost increase of the range hood 18 and to prevent the range hood from being broken or shortened in advance.
[0032]
Further, the control microprocessor in the heat source apparatus 10 connects to an external communication line such as the Internet 22 via the network adapter 20, so that a maintenance mail detected in the hot water supply central system is provided with a communication mail means such as Internet mail. Users can also be notified directly. The destination of the communication mail is preferably the user's personal computer or mobile phone, but may be other than that.
[0033]
【The invention's effect】
As described above, according to the present invention, by linking the hot water supply central system and the range hood, it is possible to provide sufficient constant ventilation for a large residence, and the maintenance time of the range hood using the linked operation. Can be monitored by the hot water supply central system, and by indicating an appropriate maintenance timing to the user, the failure of the range hood and the shortening of the service life can be prevented.
