  However, in this conventional one, since the space between the heat collecting plate installation surface and the side wall of the water storage chamber is closed, hot air is temporarily generated between the heat collecting plate and the side wall of the water storage chamber at the time of airing. Although it accumulates in the meantime, it is understood that the temperature rise efficiency around the overheating temperature sensor deteriorates over time because the amount of heat held by the hot air is transferred to the side wall of the water storage chamber, and the air whose temperature has decreased continues to accumulate below the heat collecting plate. Therefore, there is room for improvement.

In order to solve the above-mentioned problem, in claim 1 of the present invention, a device main body, a water storage chamber in the device main body for storing water, and a humidified air generating means for generating humid air from the water in the water storage chamber; A fan for supplying humidified air generated by the humidified air generating means to the room, a heater for heating the water installed in the water storage chamber, and an inclination from a side wall of the water storage chamber toward the bottom of the water storage chamber A heat collecting plate for collecting hot air generated from the heater in an aired state, and a heat collecting plate that faces the heat collecting plate across the side wall of the water storage chamber. And a control unit that stops the driving of the heater when it is determined that the empty detection state is detected by the empty detection unit.
The heat collecting plate is provided with an opening through which air can flow.

  According to a second aspect of the present invention, the heat collecting plate has an inclined surface inclined toward the bottom of the water storage chamber so as to cover the heater, and a parallel surface that is above the inclined surface and substantially parallel to the side wall of the water storage chamber. And an installation surface installed on the side wall of the water storage chamber, a gap is formed between the parallel surface and the side wall of the water storage chamber, and the air gap is formed on the side wall of the water storage chamber facing the gap. The detection means was installed.

  According to a third aspect of the present invention, the humidified air generating means includes a cylindrical rotating body that submerses the lower end in the water storage chamber and pumps up and disperses water by rotation, a mist motor that rotationally drives the rotating body, and the rotation It is characterized by comprising a colliding body with which water scattered by the rotation of the body collides.

  According to the present invention, since the air collecting plate is provided with the opening through which air can flow, hot air does not continue to accumulate between the heat collecting plate and the side wall of the water storage chamber when airing occurs, and is generated by the heater. Since the heated air continues to flow between the heat collecting plate and the side wall of the water storage chamber, the temperature rise speed of the side wall of the water storage chamber where the heat collecting plate is installed is increased, and the emptying detection means causes early airing. Can be detected.

  The heat collecting plate is installed on the inclined surface inclined toward the bottom of the water storage chamber so as to cover the heater, on the parallel surface above the inclined surface and substantially parallel to the side wall of the water storage chamber, and on the side wall of the water storage chamber. Since a gap is formed between the parallel plane and the side wall of the water storage chamber, and an emptying detection means is installed on the side wall of the water storage chamber facing the gap, the rise occurred when the emptying occurred. Since hot air always flows from the lower side to the upper side of the heat collecting plate and the temperature of the side wall of the water storage chamber rises, an abnormally high temperature can be detected by the emptying detection means at an early stage.

  The humidified air generating means includes a cylindrical rotating body that submerses the lower end of the water storage chamber, pumps up water by rotation, and scatters, a mist motor that rotationally drives the rotating body, and water scattered by rotation of the rotating body. Since it is configured with a colliding body that collides with water, a large amount of humidified air can be generated with a simple configuration that pumps the water in the water storage chamber with a rotating body and collides with the colliding body, so assembly is easy The humidified air generating means can be configured at low cost.

First, when the operation switch 45 of the operation unit 7 is operated or the operation start time set by the timer on / off switch 47 is reached, the control unit 61 opens the drain valve 34 and water in the water storage chamber 18. When the water level sensor 27 detects an OFF signal, the water supply pump 30 starts to be driven to drain the water in the water supply pipe 29, and a water replacement mode is performed in which the drain valve 34 is closed when a predetermined time has elapsed ( Step S101).

  When the water replacement mode in step S101 is completed, the controller 61 supplies the water in the water supply tank 12 into the water storage chamber 18 through the water supply pipe 29, and when a water level sensor 27 detects an ON signal, a predetermined amount of water is supplied. Is stopped in the water storage chamber 18 and the driving of the water supply pump 30 is stopped, and then the air blowing fan 23 is driven for a predetermined time to perform a start-up mode in which large water droplets adhering to the rotating body 19 are dropped (step S102).

  When the start-up mode in step S102 is completed, the control unit 61 drives the louver motor 44 to stop the louver 6 at a position perpendicular to the upper surface of the instrument body 1, and is set by the humidification switch 50 and the air volume switch 51. Based on the humidified level and the air flow level, the mist motor control means 62 and the blower fan control means 63 control the respective rotational speeds so that the mist motor 20 and the blower fan 23 are driven at a predetermined rotational speed. Based on the detected value of the temperature sensor 26, the heater 25 is controlled by switching the ON / OFF state of the heater 25 by the heater control means 64, so that the water storage temperature in the water storage chamber 18 is set to a predetermined level according to the humidification level and the air flow level. A normal operation mode for executing a mist operation within the temperature range is performed (step S103).

  Here, the normal operation mode will be described in detail. The mist motor control means 62 changes the rotational speed of the mist motor 20 within the range of 800 to 1400 rpm, and the blower fan control means 63 changes the speed of the blower fan 23 to the range of 400 to 800 rpm. In the water storage chamber 18, the mist operation is performed at a rotational speed that matches the air flow level by changing the rotational speed in the interior, and the temperature detected by the air blowing temperature sensor 35 becomes a value that matches the humidification level. The water heater temperature is changed, and the heater heater 25 is controlled by switching the ON / OFF state of the heater 25 so that the temperature detected by the water reservoir temperature sensor 26 changes within a range of about 30 to 40 ° C.

  When the operation switch 45 is turned OFF in the middle of the normal operation mode after starting the normal operation mode in step S103 or when the mist operation stop time set by the timer ON / OFF switch 47 is reached, the control unit 61 The louver motor 44 is driven to make the louver 6 stand still in an open state of about 20 ° with respect to the upper surface of the instrument body 1, the heater 25 is turned on to heat the water, and the value detected by the water storage temperature sensor 26. The sterilization operation for sterilizing the water in the water storage chamber 18 by switching the ON / OFF state of the heater 25 so that the temperature changes between 63 ° C. and 65 ° C. is executed for a predetermined time of 10 minutes, and 10 minutes After the elapse of time, a cooling operation for cooling the inside of the water storage chamber 18 is performed, and then a cleaning mode is performed in which the drain valve 34 is opened to drain the water in the water storage chamber 18 (step S10). ).

  When the cleaning mode in step S104 is completed, the control unit 61 causes the mist motor control unit 62 and the blower fan control unit 63 to drive the mist motor 20 and the blower fan 23 at a predetermined number of revolutions for a predetermined period of time, so that the inside of the water storage chamber 18 is reached. A drying mode is performed to dry the air (step S105). When a predetermined time has elapsed, the mist motor 20 and the blower fan 23 are stopped to end the drying mode, and the louver motor 44 is driven to close the louver 6. End.

Next, the detailed structure in the water storage chamber 18 and the flow of hot air in the present embodiment will be described.
First, as shown in FIGS. 7 to 9, a heat collecting plate 66 formed of stainless steel is installed on the side wall of the water storage chamber 18 and above the heater 25, and air is disposed above the heat collecting plate 66. Is provided with an opening 71 through which can be distributed.
The heat collecting plate 66 has an inclined surface 67 inclined toward the bottom of the water storage chamber 18 so as to cover the heater 25, a parallel surface 68 at a position substantially parallel to the side wall of the water storage chamber 18, and the parallel. The installation surface 69 is formed in a substantially L shape from both ends of the surface 68 and is fixed to the side wall of the water storage chamber 18.

  Further, a space 70 is formed in a space surrounded by the parallel surface 68 and the installation surface 69 constituting the heat collecting plate 66 and the side wall of the water storage chamber 18, and hot air heated by the heater 25 and having a temperature rise is formed. The air flows upward from below the gap 70, and hot air can escape from the opening 71 above the heat collecting plate 66 to above the heat collecting plate 66.

  Further, air detection means 27 is installed on the outer side wall of the water storage chamber 18 so as to face the parallel surface 68 and sandwich the water storage chamber 18, and the water storage chamber 18 heated by the amount of heat of the air passing through the gap 70. The temperature of the side wall can be detected.

  By installing the heat collecting plate 66 and the emptying detection means 27 at such a position, the heater 25 is turned off because the water storage temperature sensor 26 and the water level sensor 28 are out of order in the normal operation mode of step S103. In spite of reaching the temperature for switching to the state, the ON state continues, and the water supply pump 30 is not driven and the heater 25 is not driven in spite of the state where the water level in the water storage chamber 18 is lowered and the water needs to be supplemented. When an air-spreading state in which the water is exposed from the water surface occurs, the hot air generated by the heater 25 below the heat collecting plate 66 is guided from the inclined surface 67 to the gap 70 and rises in the gap 70. The amount of heat held by the hot air is transferred to the side walls of the water 18 to increase the temperature of the side walls of the water storage chamber 18, and the air whose temperature has been lost due to the loss of heat is pushed by the hot air rising from below the heat collecting plate 66. Exit from the opening 71 in the part above the water storage chamber 18.

  Therefore, when hot air is generated, the hot air passes through the gap 70, whereby the vicinity of the side wall of the water storage chamber 18 where the heat collecting plate 66 is installed is heated by the amount of heat of the hot air, and the temperature rises. Since the air whose temperature is lowered is pushed by the hot air rising from below 66 and escapes from the opening 71 to the upper side of the water storage chamber 18, the water whose temperature has decreased does not stay in the gap 70, so that the water storage chamber in which the heat collecting plate 66 is installed 18, the temperature rise rate of the side wall 18 is accelerated, the temperature detected by the air blow detection means 27 rises early, and the temperature comparison means 65 determines that the temperature is higher than a predetermined value for determining an abnormally high temperature. Since the driving of the heater 25 can be switched to the OFF state at an early stage, the safety of the apparatus can be improved.

  As described above, by installing the heat collecting plate 66 so that the parallel surface 68 is installed on the side wall of the water storage chamber 18 above the heater 25 and facing the emptying detection means 27, the heater 25 Even if an air blown state where water is exposed from the water surface occurs, the hot air generated by heating by the heater 25 passes through the gap 70 between the parallel surface 68 of the heat collecting plate 66 and the side wall of the water storage chamber 18, and the opening 71 Since the temperature rise speed of the side wall of the water storage chamber 18 is increased and the predetermined value for determining the high temperature abnormality at an early stage can be detected by the emptying detection means 27, the emptying state occurs. However, the heater 25 can be switched to the OFF state at an early stage to improve the safety of the apparatus.

  Further, since the air detection means 27 is installed on the outer side wall of the water storage chamber 18 facing the inner side wall of the water storage chamber 18 in the vertically downward direction of the opening 71, the hot air is most likely to be collected when an air supply state occurs. Since the emptying detection means 27 is installed on the outer wall of the water storage chamber 18 where it is easy to escape above 66, hot hot air always passes through the inner wall of the water storage chamber 18 facing the empty detection means 27. Since the detection temperature is raised, the temperature rise efficiency of the air blow detection means 27 is good, and the occurrence of the air blow state can be determined early.

  Although the present embodiment has been described with the air blow detection means 27 configured by a thermostat as the air blow detection means, the present invention is not limited to this, and an abnormally high temperature is detected by the water storage temperature sensor 26 installed in the vicinity of the air blow detection means 27. Even if it is a control to detect, even if the air-spreading detection means 27 is out of order, the storage water temperature sensor 26 detects an abnormally high temperature and the heater 25 can be switched to an OFF state. By doing so, safety can be further improved.

  Further, a configuration may be adopted in which a closed surface is provided to close the opening 71 by a predetermined range, and a certain amount of hot air is retained in the gap 70 to further increase the temperature rise efficiency. It is possible to detect the heater earlier and switch the heater 25 to the OFF state.

  Further, the air-spreading detection means 27 may also be composed of a thermistor similarly to the water storage temperature sensor 26, and the water level sensor 28 can detect the water level below the lower limit water level, and the heater 25 is moved from the water surface. The water level that is exposed may be detected by the water level sensor 28 to determine the empty state.

  Further, the configuration and control contents in the present embodiment are presented as examples, and are not intended to limit the scope of the invention, and can be implemented in various other forms. Various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
