Abstract

PROBLEM TO BE SOLVED: To provide a humidifier for making a room in a comfortable state by changing an air blowing temperature and an air blowing amount of humidified air according to a room temperature.SOLUTION: When it is determined that a room temperature is less than 15°C and a sensible temperature is low according to a room temperature detected by an intake air temperature sensor, an ON/OFF state of a heating heater is switched so that a detection temperature by an air blowing temperature sensor becomes an intake temperature +1°C and heating amount is changed, and a temperature drop of humidified air is suppressed by giving heating amount to decrease a temperature drop of humidified air due to evaporation heat or giving heating amount more than the temperature drop amount. When it is determined that a room temperature is 25°C or more and a sensible temperature is high, the heating heater is switched to an OFF state and is fixed and heating amount is set to 0, and a temperature rise of humidified air is suppressed by not giving heating amount more than the temperature drop amount of humidified air due to evaporation heat, thereby enabling a user to comfortably spend in a room because the sensible temperature becomes a comfortable room temperature by humidified air supplied to the room.SELECTED DRAWING: Figure 8

  Conventionally, this type has a humidifier that blows humidified air generated by the humidified air generating means into the room by driving a blower fan when the operation switch of the operation unit is operated, and the room detected by the humidity sensor If the relative humidity is high, the amount of humidified air supplied to the room and the amount of air blown are reduced by lowering the amount of heating in the heating means and the rotation speed of the blower fan. If the relative humidity in the room is low, the heating means Increasing the amount of humidified air supplied to the room and the amount of air blown by increasing the amount of heating and the rotational speed of the blower fan kept the indoor relative humidity at a comfortable value so that the user could spend comfortably in the room . (For example, Patent Document 1)

  However, in this conventional one, if the humidity detected by the humidity sensor is high, the heating amount by the heating means is decreased, and if the humidity detected by the humidity sensor is low, the heating amount by the heating means is increased. If the temperature is low but the relative humidity is high, low-temperature humidified air is blown and the perceived temperature decreases. Conversely, if the room is hot but the relative humidity is low, high-temperature humidified air is blown into the room and the perceived temperature increases. Therefore, the user may feel uncomfortable when receiving humid air at a temperature that does not match the room temperature, and there is room for improvement.

In order to solve the above-mentioned problem, according to claim 1 of the present invention, a device main body installed in a room, a water storage chamber in the device main body for storing water, and water in the water storage chamber is vaporized to be humidified air.

If the room temperature detected by the room temperature detection means at the start of the auto mode operation is equal to or greater than a predetermined value, the control means does not give a heating amount equal to or more than the temperature drop of the humidified air due to heat of vaporization. It is characterized by controlling the above.

Moreover, in Claim 3, the instrument main body installed indoors, the water storage chamber which stores water in this instrument main body, the humidified air generation means which vaporizes the water in this water storage chamber, and generates humid air, A blower fan that blows the humidified air generated by the humidified air generating means into the room, a heating means that changes the temperature of the humidified air blown by the blower fan by controlling the heating amount, and a temperature in the room is detected. A room temperature detecting means, a humidity sensor for detecting indoor humidity,

The heating means is controlled so as not to be given.

  According to a fourth aspect of the present invention, the control unit calculates the predetermined value based on a humidity detected by the humidity sensor and a predetermined discomfort index.

  According to this invention, if the room temperature detected by the room temperature detection means at the start of the auto mode operation is less than a predetermined value, the heating amount for reducing the temperature drop of the humidified air due to the heat of vaporization is given, or the temperature drop Since the heating means is controlled so as to give the heating amount, it is possible to suppress a decrease in the temperature of the humidified air that is blown into the room, so that the user is not uncomfortable without receiving humidified air that does not match the room temperature.

  Moreover, since the predetermined value is calculated based on the humidity detected by the humidity sensor and the predetermined discomfort index, humidified air of an appropriate amount of humidification is blown into the room due to indoor humidity and discomfort index, so it does not match room temperature. Do not feel uncomfortable without the user receiving humidified air.

Next, the operation from the start to the end of operation in this embodiment will be described based on the flowchart of FIG.
First, when the operation switch 28 of the operation unit 6 is operated or the operation start time set by the timer changeover switch 31 is reached, the control unit 43 opens the drain valve 24 to drain the water in the water storage chamber 8. When the water level sensor 19 detects an OFF signal, the water supply valve 21 is opened and a cleaning operation is performed to flush the water storage chamber 8 with water. After a predetermined time has passed, the drain valve 24 is closed to enter the water supply valve 21. When the water level sensor 19 detects an ON signal, the water replacement mode is performed to close the water supply valve 21 assuming that a predetermined amount of water has been supplied to the water storage chamber 8 (step S101). ).

  When the water replacement mode in step S101 ends, the control unit 43 drives the heater 17 based on the detection value of the temperature sensor 18 so that the water storage temperature in the water storage chamber 8 is within a predetermined temperature range (for example, 63 ° C.). The heating mode is controlled by the heater control means 46 so that the mist motor 11 and the blower fan 14 are at a predetermined number of revolutions, and the start-up mode is controlled by the mist motor control means 44 and the blower fan control means 45. Is performed (step S102).

  When the start-up mode in step S102 ends, the control unit 43 causes the mist motor 11 and the blower fan 14 to rotate at a predetermined number of rotations based on the humidification level and the airflow level set by the humidification switch 29 and the airflow switch 30. The mist motor control means 44 and the blower fan control means 45 control the rotational speed so as to drive, and the heater heater 17 is controlled by switching the ON / OFF state of the heater 17. A normal operation mode for executing a mist operation within a predetermined temperature range in accordance with is performed (step S103).

  When the end condition of the normal operation mode in step S103 is satisfied, the control unit 43 stops the mist motor 11 and then opens the drain valve 23 to drain the water in the water storage chamber 8, and when a predetermined time has elapsed, the water supply valve 21 is opened, the inside of the water storage chamber 8 is washed, the drain valve 24 is closed, and a water replacement operation for storing a predetermined amount of water in the water storage chamber 8 is performed, and the heater 17 is turned on to heat the water. A sterilization operation for performing sterilization is performed for a predetermined time, and after the predetermined time has elapsed, a cleaning mode is performed in which the water storage chamber 8 is cooled to drain the water in the water storage chamber 8 (step S104).

  When the cleaning mode in step S104 is completed, the control unit 43 controls the blower fan 14 to be driven at a predetermined rotation speed (for example, 800 rpm) by the blower fan control means 45, and blows air to the water storage chamber 8 and the blower passage 15. The drying mode for preventing the growth of bacteria by performing drying is performed (step S105), and it is determined whether the driving time of the blower fan 14 has counted a predetermined time (for example, 3 hours). To stop the operation.

Next, the control content of each humidification level and air volume level will be described with reference to FIG.
First, the control of the humidification level will be described in detail. In the state of the humidification level 1, the heater 17 is switched to the OFF state and fixed, so that the temperature decrease of the humidified air due to the heat of vaporization of the water droplets generated in the water storage chamber 8 is achieved. The temperature rise of the humidified air is suppressed without giving the above heating amount, and the humidified air that is about 6 ° C. lower than the room temperature of the room air sucked from the suction port 50 is blown into the room from the blower port 2.
Further, in the humidification level 2 state, the heating amount is changed by appropriately switching the ON / OFF state of the heater 17 so that the air temperature detected by the air temperature sensor 25 becomes the intake air temperature −2 ° C. detected by the air temperature sensor 26. By controlling, the temperature drop of the humidified air due to the heat of vaporization of the water droplets generated in the water storage chamber 8 is suppressed, and humidified air that is about 2 ° C. lower than room temperature is blown into the room from the blower port 2.
Further, in the state of the humidification level 3, the heating amount is controlled by appropriately switching the ON / OFF state of the heater 17 so that the air temperature detected by the air temperature sensor 25 becomes the intake air temperature detected by the intake air temperature sensor + 1 ° C. As a result, a heating amount equal to or higher than the temperature drop of the humidified air due to the heat of vaporization of the water droplets generated in the water storage chamber 8 is given, and humidified air that is about 1 ° C. higher than room temperature is blown into the room from the blower opening 2.
In this way, by changing the heating amount by the heater 17 for each humidification level, the temperature of the humidified air is changed and the air is blown into the room.

  By controlling the humidification level, the heating amount can be changed by switching the ON / OFF state of the heater 17, and the indoor relative humidity can be increased by blowing humidified air at a predetermined temperature. When the auto mode is selected, the humidification level is changed according to the indoor relative humidity detected by the humidity sensor 27 so that the relative humidity detected by the humidity sensor 27 satisfies the target humidity of 50% RH. Further, since the ON / OFF state of the heater 17 is switched so that the blast temperature is close to the intake air temperature, the relative humidity can be changed without significantly changing the indoor temperature. There is no discomfort caused by hitting the user.

  Next, the control of the air volume level will be described in detail. In the state of the air volume level 1, the rotation speed of the mist motor 11 is 400 rpm, the rotation speed of the blower fan 14 is 1000 rpm, and in the state of the air volume level 2, the rotation speed of the mist motor 11 is. In a state where the rotational speed of the blower fan 14 is 1200 rpm and the airflow level 3 at 600 rpm, the rotational speed of the mist motor 11 for each airflow level is driven so that the rotational speed of the mist motor 11 is 800 rpm and the rotational speed of the blower fan 14 is 1400 rpm. And the rotational speed of the blower fan 14 are stored in the air volume storage means 49. When the air volume switch 30 is operated and the air volume level is switched, the control unit 43 uses the air volume level set based on the stored value of the air volume storage means 49. The mist motor 11 and the blower fan 14 are driven so that the number of rotations becomes.

  By controlling the air flow level, it is possible to adjust the indoor relative humidity by changing the amount of nano mist and negative ions generated in the water storage chamber 8 and the amount of humidified air blown from the air outlet 2 into the room. When the level is selected as the auto mode, the air flow level is changed according to the relative humidity detected by the humidity sensor 27 so that the relative humidity detected by the humidity sensor 27 satisfies the target humidity of 50% RH. be able to.

Next, the humidification amount by the combination of each humidification level and the air volume level will be described with reference to FIG.
First, as the humidification level rises, the water temperature of the water storage chamber 8 increases, the temperature of the humidified air rises, and the amount of moisture that can be contained in the humidified air rises. When the humidification level is 3, the humidification amount is the highest.

  Further, as the air flow level increases, the rotation speed of the mist motor 11 and the blower fan 14 increases, the nano mist and negative ions generated in the water storage chamber 8 increase, and the amount of moisture contained in the humidified air increases. Since the amount of humidified air blown into the room from the air outlet 2 increases, the humidification amount is the lowest when the airflow level is 1, and the humidification amount is the highest when the airflow level is 3.

  As described above, since the humidification amount varies between the humidification level and the airflow level, when the humidification level and the airflow level are both 1, the humidification amount is 0.7 L / h, which is the lowest. When both of them are 3, the highest humidification amount is 3.0 L / H, and the humidification amount from 0.7 L / H to 3.0 L / H is increased or decreased depending on the combination of each humidification level and airflow level.

Next, control for changing the humidification level and the air volume level based on the indoor temperature detected by the intake air temperature sensor 26 will be described with reference to FIG.
First, when the humidifying switch 29 and the air volume switch 30 are set to the auto mode when the operation start is instructed by the operation switch 28, the control unit 43 confirms the temperature detected by the intake air temperature sensor 26 and checks the first predetermined value. If the detected temperature is less than 15 ° C., it is assumed that the sensible temperature is low, and the humidified level is set to 3 as shown in FIG. The heating amount is controlled by switching the ON / OFF state of the heater 17 so that the temperature becomes + 1 ° C., and a heating amount that reduces the temperature decrease of the humidified air due to the heat of vaporization of water droplets generated in the water storage chamber 8 is given or the temperature decreases. The air flow level is adjusted so that the relative humidity detected by the humidity sensor 27 is 50% RH, which is the target humidity, by providing a heating amount equal to or higher than the minute so as to suppress the temperature drop of the humidified air and increase the sensible temperature. To change the.

  Next, if the temperature detected by the intake air temperature sensor 26 is not less than 15 ° C., the control unit 43 determines whether the temperature detected by the intake air temperature sensor 26 is equal to or higher than the second predetermined value of 25 ° C. If the temperature is 25 ° C. or higher, it is assumed that the perceived temperature is high. As shown in FIG. 8 (1), the humidification level is set to 1, the heater 17 is switched off and fixed to set the heating amount to 0, The humidity sensor 27 detects the temperature of the humidified air so that the temperature of the humidified air is reduced by preventing the amount of heating equal to or greater than the temperature drop of the humidified air due to the heat of vaporization of water droplets generated in The air flow level is changed so that the relative humidity becomes 50% RH.

  Next, if the temperature detected by the intake air temperature sensor 26 is not 25 ° C. or higher, the control unit 43 determines that the temperature detected by the intake air temperature sensor 26 is a comfortable room temperature higher than 15 ° C. and lower than 25 ° C., As shown in (2) of FIG. 8, the humidification level and the air volume level are changed in pairs so that the relative humidity detected by the humidity sensor 27 is 50% RH.

  As described above, according to the room temperature detected by the intake air temperature sensor 26, if it is determined that the room temperature is less than 15 ° C. and the sensible temperature is low, the heater 17 is set so that the temperature detected by the air temperature sensor 25 becomes the intake air temperature + 1 ° C. Change the amount of heating by switching the ON / OFF state of, and give a heating amount to reduce the temperature drop of the humidified air due to the heat of vaporization, or suppress the temperature drop of the humidified air by giving a heating amount more than the temperature drop, If it is determined that the room temperature is 25 ° C. or higher and the perceived temperature is high, the heater 17 is switched to the OFF state and fixed, the heating amount is set to 0, and the heating amount higher than the temperature drop of the humidified air due to the heat of vaporization is not given. By suppressing the temperature rise of the humidified air, the sensible temperature becomes a comfortable room temperature by the humidified air supplied to the room, so that the user can spend comfortably in the room.

  In the present embodiment, the first predetermined value and the second predetermined value are set to 15 ° C. and 25 ° C. by default, respectively, but may be changed on the operation unit 6. By changing the predetermined value of 1 to 17 ° C. or the like, the indoor temperature can be raised. However, the first predetermined value is always limited so as to be lower than the second predetermined value.

Next, the control of another embodiment for changing the humidification level and the air flow level according to the comparison between the target temperature based on the discomfort index and the relative humidity and the temperature detected by the intake air temperature sensor 26 will be described with reference to FIG. .
In addition, since each element which comprises a humidification apparatus is the same as that of the said embodiment, description is abbreviate | omitted.
First, when the auto mode is set by the humidification switch 29 and the air volume switch 30, the control unit 43 substitutes the predetermined discomfort index 70 and the relative humidity detected by the humidity sensor 27 into the following (formula), A target temperature which is a predetermined value in the intake air temperature sensor 26 corresponding to the relative humidity is calculated.
(Formula) Discomfort index = 0.81T + 0.01H (0.99T-14.3) +46.3
Each of the above symbols means T: a target temperature in the intake air temperature sensor 26, and H: a relative humidity detected by the humidity sensor 27.

  Then, the control unit 43 compares the calculated target temperature with the temperature detected by the intake air temperature sensor 26, and if the temperature detected by the intake air temperature sensor 26 is higher than the calculated target temperature, the sensible temperature is high and it is sultry. Therefore, as shown in (1) of FIG. 9, the humidification level is set to 1, the heater 17 is switched off and fixed, the heating amount is set to 0, and the water droplets generated in the water storage chamber 8 are vaporized. By preventing the amount of heating equal to or greater than the temperature drop of the humidified air due to heat, the temperature rise of the humidified air is suppressed and the perceived temperature is lowered.

  Further, if the calculated target temperature and the detected temperature by the intake air temperature sensor 26 are the same value, the control unit 43 determines that the temperature is a comfortable sensible temperature and stops the mist motor 11 and the blower fan 14. The heater 17 is switched to the OFF state and fixed, the mist operation is stopped, and the room temperature and the relative humidity in the room are kept in an appropriate state.

  If the temperature detected by the intake air temperature sensor 26 is lower than the calculated target temperature, the control unit 43 determines that the sensible temperature is low and is in an uncomfortable state, as shown in (2) of FIG. The heating amount is controlled by switching the ON / OFF state of the heater 17 so that the temperature detected by the blast temperature sensor 25 becomes the intake air temperature + 1 ° C. with the level set to 3, and the humidification by the heat of vaporization of water droplets generated in the water storage chamber 8 A heating amount that reduces the temperature drop of the air is given, or a heating amount that is equal to or more than the temperature drop is given to suppress the temperature drop of the humidified air, so that the sensible temperature increases.

  As described above, the humidification level and the air flow level are changed according to the comparison between the target temperature based on the discomfort index and the relative humidity and the temperature detected by the intake air temperature sensor 26, and the ON / OFF state of the heater 17 is switched. By changing the amount of heating and changing the temperature of the humidified air so that the discomfort index approaches 70 and blowing air into the room, the user in the room can spend comfortably with the humidified air.

  In the present embodiment, the discomfort index is set to 70 by default. However, the present invention is not limited to this. For example, the discomfort index may be changeable. The standard for switching between the humidification level and the air flow level based on the detected temperature and the standard for the presence or absence of mist operation are automatically changed to obtain the room temperature and relative humidity desired by the user.

  In the present embodiment, the humidified air generating means has been described as a humidifying device of a fine water droplet generating system in which water in the water storage chamber 8 is pumped by the rotating body 10 and crushed by the porous portion 13, but the present invention is not limited to this. Even if it is a humidifying device of a warm air evaporation type that generates humidified air by blowing air to a filter immersed in the inside and changes the temperature of the humidified air by installing a heater 17 in the air flow path. Good.

  Further, in the present embodiment, the heating heater 17 that changes the heating amount by submerging in the water storage chamber 8 as a heating unit and switching the ON / OFF state is described, but not limited to this, for example, the power consumption is different. It may be an electric heater that can adjust the amount of heating by switching to each mode, and if it is determined that the room temperature is low, it switches to a mode with high power consumption and gives a heating amount equal to or more than the temperature drop due to heat of vaporization to provide humidified air If it is determined that the room temperature is high, the temperature may be switched to a mode in which the power consumption is low to suppress the increase in the temperature of the humid air without giving a heating amount equal to or lower than the temperature decrease due to the heat of vaporization.

  In this embodiment, the intake air temperature sensor 26 installed at the bottom of the instrument body 1 is used as the room temperature detection means. However, any room temperature sensor may be used as long as the room temperature can be detected. The humidity sensor 27 may be installed outside the appliance body 1 and indoors, and the room temperature and humidity can be measured. is there.
