Japanese Patent No. 4276597 JP2012-220060A

  The bathroom in winter is cold, and sudden changes in temperature during bathing cause rapid fluctuations in blood pressure, which puts a heavy burden on the body.

  Therefore, it is effective to perform a bathroom heating operation before entering the bathroom, but it is not possible to judge from outside the bathroom whether the bathroom is cold enough to require heating operation. Experience it, and if necessary, perform bathroom heating operation. In addition, it is only necessary to unconditionally perform the bathroom heating operation before bathing. However, if the bathroom is not cold enough to cause a burden on the body, the bathroom heating operation is wasted and gas and electricity are wasted. Will be consumed.

  The above-mentioned Patent Document 1 determines the timing of starting mist injection, and cannot know the temperature of the bathroom outside the bathroom, and detects the temperature of the bathroom with a thermistor provided inside the bathroom heating device body. Therefore, it is easy to be affected by the hot air accumulated inside the bathroom heating apparatus main body, and it is difficult to accurately detect the temperature of the bathroom.

  The above-mentioned Patent Document 2 changes the timing of the mist injection start according to the temperature near the wall surface of the bathroom, and cannot detect the temperature of the bathroom outside the bathroom, and detects the temperature near the wall surface of the bathroom. Therefore, there is a problem that a dedicated temperature sensor for doing so must be installed in the bathroom, which increases the cost.

  The present invention has been made paying attention to such a situation, and provides a bathroom heating device that can easily know whether or not a bathroom heating operation is necessary without entering the bathroom with an inexpensive configuration. The purpose is to do.

  In order to achieve the above object, the present invention is configured as follows.

(1) A bathroom heating apparatus according to the present invention includes a ventilation fan that exhausts air in the bathroom, a circulation fan that circulates the air in the bathroom, and heating means that heats the circulating air using a heat medium from a heat source unit, And it has a temperature sensor provided in the inflow path of the air in the bathroom, and the bathroom heating device main body installed in the bathroom,
An outdoor operation unit installed outside the bathroom, having a heating recommendation display unit for performing a solicitation display for encouraging bathroom heating operation;
Controlling the ventilation fan, the circulation fan, the heating means and the outdoor controller, and a control means for receiving a detection output of the temperature sensor and a command from the outdoor controller,
The control means recommends the heating when the detected temperature is lower than the set temperature for display based on a detected temperature of the temperature sensor, a preset temperature for display, and a preset temperature for display release. The solicitation display is performed on the display unit, and when the detected temperature is equal to or higher than the display cancellation set temperature, the solicitation display is canceled .
The display cancellation setting temperature corresponds to a first display cancellation setting temperature corresponding to an operation in which the heating medium is not used, and corresponds to an operation in which the heating medium is used, and more than the first display cancellation setting temperature. A high preset temperature for canceling the second display is preset,
The control means selects the first display cancellation setting temperature or the second display cancellation setting temperature according to whether or not the heating medium is used, and the heating recommendation display unit The cancellation of the solicitation display is controlled .

  According to the present invention, when the bathroom temperature is low, a solicitation display for encouraging heating operation is made on the heating recommendation display section of the outdoor controller. It is possible to easily determine whether or not it is better to perform the bathroom heating operation without providing a dedicated temperature sensor for detecting the above.

  During operation in which the heat medium is not used, the temperature sensor provided in the bathroom heating device body can detect the temperature of the bathroom without being affected by the heat medium, whereas in operation in which the heat medium is used, The temperature sensor provided in the bathroom heating device body is affected by the heat medium, and detects a temperature higher than the temperature of the bathroom. Therefore, when the temperature of the bathroom is low and the solicitation display prompting the bathroom heating operation is being performed, the solicitation display is canceled when the temperature exceeds the same set temperature for canceling the display regardless of the use of the heat medium. Then, at the time of the driving | operation which uses a heat medium, since the temperature of a bathroom has not fully risen, since the detection temperature of a temperature sensor is high, the malfunction that a solicitation display is cancelled | released arises.

According to the present invention , as the display cancellation setting temperature for canceling the solicitation display, the first display cancellation setting temperature corresponding to the operation in which the heat medium is not used, and higher than the first display cancellation setting temperature, The second display cancellation set temperature corresponding to the operation in which the heat medium is used is set, and the control means determines whether the first display cancellation set temperature or the temperature is in the operation in which the heat medium is used. Since the cancellation of the invitation display is controlled by selecting the second display cancellation setting temperature, it is possible to prevent a problem that the invitation display is canceled even though the bathroom temperature is not sufficiently increased.

( 2 ) In another embodiment of the present invention, when the control means performs an operation using the heating medium in the display state where the solicitation display is performed, a set time from the end of the operation is set. The second display cancellation set temperature is selected until the time has elapsed, and after the set time has elapsed, the first display cancellation set temperature is selected.

  According to this embodiment, until the set time (for example, 30 minutes) elapses from the end of the operation using the heat medium, there is hot air accumulated in the bathroom heating apparatus main body, so-called hot mass, The solicitation display is canceled when the sensor detects a temperature equal to or higher than the second display cancellation set temperature corresponding to the use of the heat medium. In addition, after the set time has elapsed from the end of the operation using the heat medium, it is assumed that the heat accumulation in the bathroom heating apparatus body has been eliminated, and the temperature sensor corresponds to the time when the heat medium is not used. The solicitation display is canceled when a temperature equal to or higher than the set temperature for 1 display cancellation is detected.

(3) The onset Ming, ventilation fan for discharging air in the bathroom, a circulation fan for circulating the air in the bathroom, the air circulation, heating means for heating the heat medium from the heat source apparatus, and the bath And having a temperature sensor provided in the inflow path of the air in the bathroom heating device main body installed in the bathroom,
An outdoor operation unit installed outside the bathroom, having a heating recommendation display unit for performing a solicitation display for encouraging bathroom heating operation;
Controlling the ventilation fan, the circulation fan, the heating means and the outdoor controller, and a control means for receiving a detection output of the temperature sensor and a command from the outdoor controller,
The control means recommends the heating when the detected temperature is lower than the set temperature for display based on a detected temperature of the temperature sensor, a preset temperature for display, and a preset temperature for display release. The solicitation display is performed on the display unit, and when the detected temperature is equal to or higher than the display cancellation set temperature, the solicitation display is canceled.
In the display release state where the solicitation display is released, the control means continues the display release state when performing the operation using the heating medium, and until the set time elapses from the end of the operation. The display release state is maintained over a period.

  In the display release state in which the solicitation display is released, the detected temperature is equal to or higher than the display set temperature, but the actual bathroom temperature may be lower than the detected temperature. Therefore, when an operation using a heating medium (for example, heating operation) is started in a state where the actual bathroom temperature is lower than the detected temperature, first, the detected temperature is displayed by sucking in cold air in the bathroom. The solicitation display for encouraging bathroom heating operation is performed when the temperature is lower than the set temperature, and then the detected temperature immediately rises to the display cancel set temperature or higher, and the solicitation display is cancelled. As a result, when the operation using the heating medium is started, the solicitation display changes from “display cancellation” → “display” → “display cancellation”, even though the operation using the heating medium is started. There is a problem that a time zone in which a solicitation display for encouraging bathroom heating operation is generated occurs.

According to the present invention , when the operation using the heat medium is performed in the display canceling state in which the solicitation display for encouraging the bathroom heating operation is cancelled, the display is forcibly maintained in the display canceling state, so that unnecessary solicitation display is performed. Can be prevented.

  In addition, it is assumed that the user stops the operation immediately after starting the operation using the heating medium in the display cancellation state in which the solicitation display is cancelled. However, it is conceivable that the bathroom temperature is lowered to a temperature at which the solicitation display is performed.

Since the user has consciously stopped the operation using the heat medium, it is not preferable to immediately display the solicitation prompting the heating operation, and according to the present invention , when the operation using the heat medium is finished. During the period until the set time (for example, 10 minutes) elapses, it is possible to eliminate the problem that the solicitation display is performed immediately after the end of the operation using the heating medium by maintaining the solicitation display in the display release state. .

(4) The onset Ming, ventilation fan for discharging air in the bathroom, a circulation fan for circulating the air in the bathroom, the air circulation, heating means for heating the heat medium from the heat source apparatus, and the bath And having a temperature sensor provided in the inflow path of the air in the bathroom heating device main body installed in the bathroom,
An outdoor operation unit installed outside the bathroom, having a heating recommendation display unit for performing a solicitation display for encouraging bathroom heating operation;
Controlling the ventilation fan, the circulation fan, the heating means and the outdoor controller, and a control means for receiving a detection output of the temperature sensor and a command from the outdoor controller,
The control means recommends the heating when the detected temperature is lower than the set temperature for display based on a detected temperature of the temperature sensor, a preset temperature for display, and a preset temperature for display release. The solicitation display is performed on the display unit, and when the detected temperature is equal to or higher than the display cancellation set temperature, the solicitation display is canceled.
The control means, when performing the solicitation display, if the freeze prevention operation is being performed, performs the solicitation display, and over a period until a set time elapses from the end of the freeze prevention operation. Continue the solicitation display.

According to the present invention , when the freeze prevention operation is performed when performing the invitation display for encouraging the bathroom heating operation, since the bathroom is at a low temperature, the invitation display is forcibly continued and the freeze prevention operation is completed. During the period until the set time (for example, 60 minutes) elapses, since the heat is trapped inside the bathroom heating device body, the solicitation display is continued so that the invitation display is not unfairly cancelled. To do.

( 5 ) In another embodiment of the present invention, there is provided a setting operation section capable of switching and setting the display set temperature by operation.

  According to this embodiment, the user can arbitrarily select and set a display setting temperature that is a reference for performing a solicitation display for encouraging bathroom heating operation, so that a suitable solicitation display corresponding to the physical condition and constitution can be performed. it can.

  According to the present invention, it is possible to easily know whether or not bathroom heating operation is necessary with an inexpensive configuration without entering the bathroom, and appropriately perform instruction operation of the bathroom heating operation as necessary. be able to.

When the stop switch 39 is pressed by the user during the heating operation, the control unit B is instructed to stop the heating operation, and the circulation fan 14a is stopped, the thermal valve 17 is closed, the outlet 3 is closed, and the monitor is monitored. The lamp is turned off and the timer display 31 disappears, and the automatic heating operation ends.

  Although the bathroom heating apparatus is configured as described above, in this embodiment, when the bathroom temperature is low, the bathroom heating operation is promoted so that it can be determined whether bathroom heating is necessary from outside the bathroom. The solicitation display is performed by the outdoor controller 5.

That is, as shown in FIG. 5, the outdoor operation unit 5 is provided with a heating recommendation display unit 60 that performs solicitation display for encouraging bathroom heating operation when the bathroom temperature is low. The heating recommendation display unit 60 includes a display lamp 61 made up of an LED or the like that lights and displays that the heater is in a recommended heating state, and a setting operation unit that changes the setting of the set temperature for display θ1 that is a reference for performing the lighting display. Temperature setting switch 62, and a monitor lamp 63 group for notifying the set state by "high", "medium", and "low".

  In this embodiment, the solicitation display for encouraging bathroom heating operation is performed by turning on the display lamp 61, and the cancellation of the solicitation display is performed by turning off the display lamp 61.

  The display setting temperature θ1, which is a criterion for whether or not to perform the solicitation display for encouraging bathroom heating operation, that is, whether or not to turn on the display lamp 61, is “high” by the user operating the temperature setting switch 62. (20 ° C.), “medium” (15 ° C.), “low” (10 ° C.), and “not displayed” can be selected, and are set to “medium” at the time of shipment. Then, the temperature setting switch 62 can be selected by cyclically switching in the order of “medium” → “low” → “high” → “not display” → “medium” for each operation by the user. The temperature setting state is displayed by lighting of the corresponding monitor lamp 63. In addition, in the setting of “not display”, all the monitor lamps 63 are turned off.

  The basic processing of display control in the solicitation display for encouraging bathroom heating operation is shown in the flowchart of FIG.

  The bathroom temperature thermistor TH3 constantly detects the bathroom temperature (strictly speaking, the temperature of the air inflow path in the bathroom heating device A). First, the display set temperature θ1 is set, that is, the above “not display”. (Step n1), if the detected temperature θ by the bathroom temperature thermistor TH3 is less than the display setting temperature θ1 (θ <θ1) (step n2), the display lamp 61 is turned on and the heating operation is performed. When solicitation display is performed (step n3) and the detected temperature θ is equal to or higher than the preset display canceling set temperature θ2 (θ ≧ θ2) (step n7), the display lamp 61 is turned off and the solicitation display is cancelled. (Step n8).

  Here, the display cancellation setting temperature θ2 for turning off the display lamp 61 to cancel the solicitation display corresponds to the first display cancellation setting temperature corresponding to the operation not using hot water and the operation using hot water. The second display cancellation set temperature is set in advance, and the control unit B selects any one of the display cancellation setting temperatures θ2 based on the operation status, and controls the cancellation of the solicitation display.

  In operation without using hot water, the bathroom temperature thermistor TH3 installed in the main body 9 of the bathroom heating device A is not affected by the heat of the hot water, so the detected temperature is substantially equal to the temperature of the bathroom. In operation using hot water, the bathroom temperature thermistor TH3 is affected by the heat of the hot water, so that the detected temperature is higher than the temperature of the bathroom.

  Therefore, in this embodiment, as shown in Table 1 below, the first display release setting temperature that is the display release setting temperature θ2 when the operation in which hot water is not used is performed (other than when hot water is used) is used for display. A value obtained by adding 2 ° C. to the set temperature θ1 (22 ° C., 17 ° C., 12 ° C.), and for the second display release that is the set temperature θ2 for display release when operation using hot water is performed (when using hot water) The set temperature is uniformly 25 ° C., which is higher than the first display release set temperature.

  When the temperature of the bathroom is low, as shown in FIG. 7, after the display lamp 61 is turned on and the solicitation display is made (step n3), operation using heating water (heating, drying, mist sauna, etc.) is performed. A display cancellation setting temperature θ2 (25 ° C.) when hot water is used is set (steps n4 and n5), and this display cancellation setting temperature θ2 is compared with the detection temperature θ of the bathroom temperature thermistor TH3 to display the detection temperature θ. When the set temperature for release θ2 is equal to or higher than θ2 (θ ≧ θ2) (step n7), it is determined that the bathroom temperature is sufficiently high, and the display lamp 61 is turned off to cancel the solicitation display (step n8).

  Also, when the temperature of the bathroom is low and the display lamp 61 is turned on and the solicitation display is made (step n3), operation without using hot water (cool air, ventilation, water mist, 24-hour ventilation, etc.) is performed, or When no operation is performed, corresponding to the selection setting of the display setting temperature θ1, the display cancellation setting temperature θ2 (θ1 + 2 ° C. = 22 ° C., 17 ° C., except when using hot water 2 ° C. higher than that) 12 ° C.) is set (steps n4 and n6), and the display cancellation setting temperature θ2 is compared with the detection temperature θ, and when the detection temperature θ is equal to or higher than the display cancellation setting temperature θ2 (θ ≧ θ2) (step n7), the display lamp 61 is turned off and the solicitation display is released (step n8).

  Moreover, although not shown in the flowchart of FIG. 7, in this embodiment, the following control is performed.

  (1) Until the set time U1 (for example, 30 minutes) elapses from the time when the operation using hot water is completed, the bathroom heating apparatus main body 9 has a hot spot even if the operation using hot water is completed. Therefore, when the detected temperature θ is detected to be equal to or higher than the second display cancellation setting temperature (25 ° C.) that is the display cancellation setting temperature θ2 when hot water is used, the display lamp 61 is turned off to cancel the solicitation display. Further, after the set time U1 has elapsed since the end of the operation using hot water, the detected temperature θ is assumed to be other than when the original hot water is used. The display lamp 61 is extinguished and the solicitation display is canceled when the first display cancellation set temperature (22 ° C., 17 ° C., 12 ° C.) or more, which is the display cancellation set temperature θ2, is detected.

  (2) When the display lamp 61 is turned off, that is, when the operation using hot water is performed in the display release state in which the solicitation display for encouraging the bathroom heating operation is released, the display lamp 61 is compulsory. During the period from when the operation using hot water is completed until the set time U2 (for example, 10 minutes) elapses, the display lamp 61 is kept off and the solicitation display is cancelled. Continue state.

  In this case, in the state where the display lamp 61 is turned off and the solicitation display is released, the detected temperature θ is equal to or higher than the display set temperature θ1, but the actual bathroom temperature is lower than the detected temperature θ. There is also. Therefore, when an operation using hot water (for example, a heating operation) is started in a state where the actual bathroom temperature is lower than the detected temperature θ, first, the circulation fan 14a is activated to suck in cool air in the bathroom. Thus, the detected temperature θ becomes lower than the display setting temperature θ1, the display lamp 61 is turned on and the solicitation display is performed, and then the detection temperature θ rises immediately and the display canceling set temperature θ2 (25 ° C.) or higher. Then, the display lamp 61 is turned off and the solicitation display is released. As a result, when the operation using hot water is started, the display lamp 61 changes from “off” to “lighting” to “off”, and even though the operation using hot water is started, the display lamp 61 is changed. A problem arises in that a time zone occurs during which a solicitation display is made to illuminate and encourage bathroom heating operation.

  In this embodiment, as described above, when the operation using hot water is performed in a state in which the display lamp 61 is turned off, that is, in a display release state in which the solicitation display is released, the display lamp 61 is compulsory. During the period from when the operation using hot water is completed until the set time U2 (for example, 10 minutes) elapses, the display lamp 61 is kept off and the solicitation display is cancelled. Continue state.

  As a result, when the display lamp 61 is turned off and the solicitation display is cancelled, the display lamp 61 is prevented from being unnecessarily lit and the solicitation display is not performed when driving using hot water. can do.

  In addition, it is assumed that the display lamp 61 is turned off and the user stops the operation immediately after starting the operation using the hot water in the display cancellation state in which the solicitation display is cancelled. It is conceivable that the bathroom temperature is lowered to a temperature at which the solicitation display is performed without any heat accumulation.

  However, since the user has consciously stopped the operation using hot water, it is not preferable to immediately display a solicitation for encouraging bathroom heating operation using hot water. Therefore, according to this embodiment, Until the set time U2 (for example, 10 minutes) elapses from when the operation using the is completed, the solicitation display is performed immediately after the operation using the hot water is completed by maintaining the display of the invitation display in the display release state. The trouble can be eliminated.

  (3) Further, when the solicitation display is performed by turning on the display lamp 61, the freeze prevention operation, that is, the heat valve 17 is opened to supply the hot water from the heat source unit 16 to the hot air heat exchanger 13. When the freeze prevention operation is performed to prevent the pipes and the like from freezing, since the bathroom is at a low temperature, the lighting state of the display lamp 61, that is, the solicitation display is forcibly maintained. Further, since the heat is trapped until the set time U3 (for example, 60 minutes) elapses after the freeze prevention operation in which the circulation fan 14a and the ventilation fan 14b are not operated, the detected temperature becomes higher than the bathroom temperature. In order to prevent the display lamp 61 from being unnecessarily turned off, the lighting state of the display lamp 61 is maintained and the solicitation display is continued.

  Note that the set times U1, U2, and U3 are examples, and are not limited to the above.

  As described above, according to the present embodiment, the bathroom temperature thermistor TH3 provided in the bathroom heating device main body 9 can be used to indicate to the outside whether bathroom heating is necessary, in order to detect the bathroom temperature. It is possible to know in advance whether bathroom heating is necessary or not without entering the bathroom and checking the temperature of the bathroom without experiencing a dedicated temperature sensor.
