BACKGROUND OF THE INVENTION
The present invention relates to a clothes drying / heating / ventilating apparatus for bathrooms that is installed in a bathroom and performs drying, heating, and ventilation of clothes and the like.
[0002]
[Prior art]
FIG. 8 is a conceptual diagram showing a state in which the bathroom clothes drying and heating ventilator is installed in the bathroom. In FIG. 8, 111 is a bathroom. Reference numeral 112 denotes a bathtub, which is installed on the lower surface of the bathroom 111. Reference numeral 113 denotes a washing place adjacent to the bathtub 112. Reference numeral 114 denotes a bathroom clothes drying and heating ventilation device that is located on the top of the bathtub 112 and is installed on the ceiling surface of the bathroom 111. Reference numeral 115 denotes an opening facing the bathroom 111 side of the bathroom clothing drying / heating ventilator 114. Hot air for drying or heating blows out from the opening 115 into the bathroom 111, or for heating. The radiant heat is radiated. In addition, 116 is the warm air which blows off from the opening part 115, and the arrow has shown the direction of blowing.
[0003]
There are two types of drying: bathroom wall / floor drying and clothes drying. Of these, it is more effective to send hot air blown out mainly to the washroom 113 for drying the bathroom. This is described in “Mitsubishi Bus Drying / Heating / Ventilation System, Technical Manual”. Furthermore, in the type of model in which the heating function is generally strengthened, the far-infrared quartz heater is tilted and the heating effect is increased mainly by radiating radiant heat toward the washing area.
[0004]
FIG. 9 is a cross-sectional view of a conventional bathroom clothes drying / heating / ventilating apparatus with enhanced heating function.
In FIG. 9, 121 is a far-infrared quartz heater. Reference numeral 122 denotes a reflector. The reflection plate 122 includes a first side wall reflection plate 122a, a second side wall reflection plate 122b, a first inclined upper reflection plate 122c, and a second inclined upper reflection plate 122d so as to surround the far-infrared quartz heater 121. ing. A suction port 123 sucks air in the bathroom into the apparatus. Reference numeral 124 denotes an opening for blowing warm air or radiating radiant heat. A wind direction guide 125 is fixed to the opening 124. 126 is a heater for generating warm air. Reference numeral 127 denotes a blower that blows air sucked from the suction port 123 toward the heater 126. Reference numeral 128 denotes a hot air blown out from the opening portion 124, and an arrow indicates a flow direction. Reference numeral 129 denotes an air path formed between the reflecting plate 122 and the wind direction guide 125. Reference numeral 130 denotes an airflow flowing through the air passage 129, and an arrow indicates the direction of flow.
[0005]
Next, the operation will be described. In order to dry the bathroom 111 and clothes, in order to heat before bathing, the operation which blows out warm air is performed. In this case, the heater 126 for generating hot air is energized and the blower 127 operates to blow air. The blower sucks air in the bathroom 111 from the suction port 123, and the blower 127 sends the air to the heater 126 for generating hot air. Thereafter, the air is warmed by the heater 126 and blown out from the opening 124 through the air passage 129 between the reflector 122 and the airflow direction guide 125.
Note that since the warm air 128 blows out and the radiant heat may be emitted from the opening 124, the air 128 heated by the heater 126 flows almost horizontally through the narrow air passage 129 and then flows through the air guide 125. It is blown out from the opening 124 by changing the angle greatly. Further, when heating is performed during bathing, the far-infrared quartz heater 121 is energized, and radiant heat radiated using the reflector 122 is radiated into the bathroom 111 from the opening 124.
[0006]
Here, the general shape of the wind direction guide 125 for blowing the warm air 128 blown out from the opening 124 toward the washing place 113 will be described. FIG. 10 is a cross-sectional view showing a cross-sectional shape of the wind direction guide 125. In FIG. 10, reference numeral 131 denotes an airflow flowing between the wind direction guides 125. The wind direction guide 125 is made of a plate having a fixed cross-section of a dogleg shape, and a root portion having a length of about 7 mm is directed in the vertical direction. And the part of about 3 mm length of the front-end | tip has the structure inclined 60 degree | times. As a result, the air flow 130 flowing through the air passage 129 is bent at a substantially right angle at the root portion of the wind direction guide 125 to become an air flow 131 flowing in the vertical direction, and then bent by about 30 degrees at the tip portion inclined by 60 degrees. As a result, the air is blown toward the washing place 113. Here, it is assumed that the interval between the wind direction guides 125 is about 10 mm, and the thickness of the guides 125 is about 0.8 mm. However, it is conceivable that the cross section of the wind direction guide has a rectangular shape and is installed at the opening 124 with an inclination of 30 degrees, but in this case, the warm air flows in a direction closer to the ceiling surface than 30 degrees. It is not possible to give warm air in the direction of the washing area.
[0007]
[Problems to be solved by the invention]
As described above, in the conventional clothes drying and heating ventilator 114 for bathrooms, the warm air is blown from the narrow air passage 129 between the reflector 122 and the opening 124 toward the washing place 113, and the airflow in the shape of a dog-legged shape. After the airflow is bent in the vertical direction by the guide 125, the airflow is further tilted to give warm air to the target position. As a result, the hot air can be blown at an angle toward the washing place, the apparatus configuration can be simplified, and the efficiency is improved. However, in such a shape, it cannot be said that the radiation heat radiation from the far-infrared quartz heater 121 is sufficiently efficient. That is, since the radiant heat goes straight, a phenomenon occurs in which a part of the radiant heat is blocked by the presence of the wind direction guide 125.
[0008]
FIG. 11 is a diagram showing the direction of radiant heat radiated in the vicinity of the wind direction guide 125. In FIG. 11, 132 is radiant heat, and the arrow indicates the direction of radiation. Here, the radiant heat 132 is radiated from between the wind direction guides 125, but the direction of the strongest radiation is not 30 degrees, but is about 15 degrees as shown in FIG. This is because the root of the wind direction guide 125 is directed in the vertical direction and has an angle of 0 degrees and the tip portion is 60 degrees. With respect to the direction of about 15 degrees, the interval between the wind direction guides 125 is 7.6 mm, and the apparent thickness of the wind direction guide 125 is 2 mm. Therefore, when the aperture ratio is calculated from a value obtained by dividing the interval by the sum of the interval and the thickness (7.6 mm / (7.6 mm + 2 mm) = 0.79), the aperture ratio is a small value of 79%.
[0009]
As described above, the conventional clothes drying and heating ventilator 114 for bathrooms has a problem that radiation efficiency is deteriorated because radiation is radiated by the wind direction guide in radiation heat for heating during bathing. In addition, a strong angle of radiant heat is determined from the positional relationship with the wind direction guide, and there is a problem that it is extremely difficult to radiate radiant heat in a target direction. In order to make the direction of radiant heat and the direction of warm air the same direction, a delicate design is required. Furthermore, both a heater for blowing out hot air and a far-infrared quartz heater for generating radiant heat must be provided, resulting in a problem that the apparatus becomes large-scale.
[0010]
The present invention has been made to solve the above-described problems, and a first object is to make the direction of radiant heat radiated from the far-infrared heater the same as the direction of hot air. An object of the present invention is to provide a bathroom-drying / heating / ventilating apparatus capable of increasing radiation efficiency.
A second object of the present invention is to provide a bathroom clothes drying and heating ventilator capable of easily downsizing the apparatus configuration.

[0017]
DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
FIG. 1 is a cross-sectional view of a bathroom clothes drying and heating ventilator according to Embodiment 1 of the present invention.
In FIG. 1, reference numeral 1 denotes a bathroom clothes drying and heating ventilator. 2 is a far-infrared quartz heater. Reference numeral 3 denotes a reflector. The reflection plate 3 includes a first side wall reflection plate 3a, a second side wall reflection plate 3b, a first inclined upper reflection plate 3c, and a second inclined upper reflection plate 3d so as to surround the far-infrared quartz heater 2. ing. Reference numeral 4 denotes a suction port for sucking air in the bathroom into the apparatus 1. Reference numeral 5 denotes an opening for blowing warm air or radiating radiant heat. An opening frame 6 is attached so as to surround the opening 5. Reference numeral 7 denotes a wind direction guide, which is fixed to a movable portion 8 provided in two opposite sides of the opening frame 6 and operable in the horizontal direction. 9 is a heater for generating warm air. A blower 10 blows air sucked from the suction port 4 in the direction of the heater 9.
[0018]
Next, the configuration in the vicinity of the wind direction guide in the bathroom clothes drying and heating ventilator will be described with reference to the cross-sectional view of FIG.
In FIG. 2, 21 is a fixing shaft provided at the tip of the airflow direction guide 7 formed on the bathroom side on the bathroom side. The fixing shaft 21 is fixed to the opening frame 6 so as to be slightly movable in the vertical direction. The wind direction guide 7 can be rotated at the center. Reference numeral 22 denotes a projection for maintaining a gap provided at the tip of the wind direction guide 1 on the reflecting plate side. The movable portion 8 has a spacing holding projection 22 on each of the wind direction guides 7 fixed at predetermined intervals so as to be rotatable. Accordingly, when the movable portion 8 moves in the left-right direction in FIG. 2, the angles of the plurality of wind direction guides 7 change at a time. The movement of the movable portion 8 is controlled by a microcomputer (not shown) according to a control program created in advance. Reference numeral 23 denotes warm air, and an arrow indicates a blowing direction.
[0019]
Next, the operation will be described.
For example, when warm air is blown out during drying operation or heating before bathing, the direction of the wind direction guide 7 is set as shown in FIG. That is, the wind direction guide 7 is directed in the vertical direction with respect to the movable portion 8. Thus, as in the conventional case, the warm air sent from the blower 10 through the heater 9 through the heater 9 by the wind direction guide 7 in the horizontal direction is bent 90 degrees, directed downward, further inclined, and angled toward the washing area. It blows out from the opening part 5 and can perform drying and heating.
[0020]
Next, when radiating heat from the far-infrared quartz heater 2 is radiated for heating during bathing, the movable portion 8 moves to the left in FIG. 2 so that the direction of the wind direction guide 7 is slightly inclined as shown in FIG. Changing the direction, an electric current is passed through the far-infrared quartz heater 2. In FIG. 3, 24 indicates the direction in which the radiation heat is most intensely emitted. In FIG. 3, the moving part 8 is moved to the left and rotated in the counterclockwise direction so that the wind direction guide 7 is further laid, so that the direction 24 with the strongest radiation is directed in the same direction as the warm air. Also in, radiant heat can be radiated mainly in the direction of the washing place, and heating can be performed effectively.
[0021]
In this way, by rotating the entire airflow direction guide 7 having a cross-sectional shape, the radiation heat can be radiated toward the washing place in the same manner as the warm air. In the configuration of the wind direction guide 7, when the interval between the protrusions 22 is 10 mm and the angle of the cross is 60 degrees, the wind direction guide 7 is used at an angle where the radiation heat is radiated to 30 degrees. The apparent thickness is 2 mm, and the distance between the wind direction guides 1 is 6.7 mm. For this reason, the aperture ratio is 77 (6.7 / (6.7 + 2))%, and the radiation efficiency is almost the same as the conventional one.
[0022]
Embodiment 2. FIG.
FIG. 4 is a cross-sectional view showing the vicinity of a wind direction guide in a bathroom clothes drying and heating ventilator according to Embodiment 2 of the present invention. In addition, the same code | symbol is attached | subjected to the component which is the same as that of FIG. 1, and corresponds.
In FIG. 4, the first wind direction guide 31 having a rectangular cross section in the bathroom side direction and the second wind direction guide 32 having a rectangular cross section in the reflector direction are opposed to the movable portion 8. So that it is fixed. Reference numeral 33 denotes a fixing shaft provided at the front end of the first wind direction guide 31 on the bathroom side. The fixing shaft 33 is fixed to the opening frame 6 so as to be slightly movable in the vertical direction, and the first wind direction guide 31 is centered on the fixing shaft 33. Can be rotated. Reference numeral 34 denotes a spacing holding projection provided at the tip of the first wind direction guide 31 on the reflecting plate side. The protrusions 34 are rotatably fixed to the movable portion 8 at predetermined intervals, and the angle of the first wind direction guide 31 can be changed by moving in the horizontal direction. When the movable part 8 is located on the leftmost side, the first wind direction guide 31 is installed so as to be about 30 degrees from the direction with respect to the movable part 8 as shown in FIG.
[0023]
Reference numeral 35 denotes an elongated hole formed near the center of the second wind direction guide 32. Reference numeral 36 denotes a fixing support portion fixed to the opening frame 6, and is inserted into the hole portion 35. Note that the bathroom-side tip of the second wind direction guide 32 is rotatably fixed to the protrusion 34 of the first wind direction guide 31. Therefore, the second wind direction guide 32 can be positioned in a tilting direction by rotating the movable portion 8 along the fixed support portion 36 when the movable portion 8 moves and rotating around the projection 34. Become. When the movable part 8 is located on the leftmost side in FIG. 4, the second wind direction guide 32 is installed so as to be perpendicular to the movable part 8. Reference numeral 37 denotes a hot air blowing direction.
[0024]
Next, the operation will be described.
For example, when blowing warm air during drying operation or heating before bathing, the movable portion 8 is located on the left side, so that the direction of the second wind direction guide 32 is as shown in FIG. The first wind direction guide 31 is about 30 degrees with respect to the direction of the movable portion 8. Thus, as in the prior art, the U-shaped airflow direction guide is configured by the combination of the first airflow direction guide 31 and the second airflow direction guide 32, and the warm air can be blown out at an angle of 30 degrees. .
[0025]
Next, in the case of radiating radiant heat from the far-infrared quartz heater 2 for heating during bathing, the movable portion 8 moves to the right side, so that the angle formed by the first wind direction guide 31 and the second wind direction guide 32 is increased. Alternatively, it can be linear as shown in FIG. Here, 38 indicates a direction in which radiation of radiant heat is strongest. When the movable portion 8 is moved to the right side, the fixing shaft 33 is slightly shifted downward, and the first wind direction guide 31 moves clockwise around the protrusion 34. Further, the second wind direction guide 32 moves counterclockwise about the protrusion 34 as the hole 35 is displaced along the fixed support portion 36. In this way, the cross section of the first wind direction guide 31 and the cross section of the second wind direction guide 32 are linear, and in this state, the strongest radiation direction 38 is the same as the hot air direction. By directing, the heating during bathing can also direct the radiant heat mainly toward the washing place, and heating can be performed effectively.
[0026]
In this way, by rotating the first wind direction guide 31 and the second wind direction guide 32, the radiant heat can be radiated toward the washing place in the same manner as the warm air. Further, when the distance between the projections 34 is 10 mm, the first wind direction guide 31 or the second wind direction guide 32 can ensure a distance of 7.9 mm when the radiation 34 is radiated. Has a large value of 91 (7.9 / (7.9 + 0.8))%, so that the radiation efficiency can be improved.
[0027]
Embodiment 3
6 is a cross-sectional view of a bathroom clothes drying and heating ventilator according to Embodiment 3 of the present invention. In the bathroom clothes drying and heating ventilator of FIG. 1, the position of the second side wall reflector located on the blower side is shown. Can be changed. In addition, the same code | symbol is attached | subjected to the component which is the same as that of FIG. 1, and corresponds.
In FIG. 6, reference numeral 11 denotes a movable side wall reflector, which is rotatable about the shaft 12 at the lower part of the main body.
[0028]
The following operation will be described.
When energizing the far-infrared quartz heater 2 for heating during bathing and radiating radiant heat to the bathroom, the movable side wall reflector 11 surrounds the radiation from the far-infrared quartz heater 2 with the reflector as shown in FIG. It moves so as to be in contact with another reflecting plate so as to be reflected inside the generated space, and as a result, radiant heat from the far-infrared quartz heater 2 is radiated only from the opening 5.
[0029]
Next, when blowing out warm air such as during drying operation or heating before bathing, as shown in FIG. 7, the movable side wall reflector 11 rotates about the shaft 12 and falls down, and horizontally in the direction of the blower 10. Therefore, an air path from the blower 10 to the opening 5 through the far-infrared quartz heater 2 is formed. 13 is an airflow flowing around the far-infrared quartz heater 2, 14 is warm air blown out from the opening 5, 15 is airflow blown out from the blower 10, and 16 is airflow sucked into the suction port 24. .
[0030]
When blowing warm air, the fan 10 and the far-infrared quartz heater 2 are energized. Thereby, the blower 10 sucks the airflow 16 from the suction port 4 and sends out the blown airflow 15. Since the movable side wall reflector 11 is in an open state, the blown airflow 15 flows toward the far-infrared quartz heater 2 and is heated as an airflow 13 flowing around the heater. After that, the airflow is guided by the airflow direction guide 7 in the opening 5 to become a blown airflow 14, and drying and heating can be performed effectively. In this way, if the movable side wall reflector 11 is rotated in accordance with the operating state, it is possible to radiate radiant heat and generate hot air with only the far-infrared quartz heater 2, and to simplify the apparatus configuration. .
[0031]
【The invention's effect】
As described above, in the present invention, the direction of the hot air and the direction of radiation of the radiant heat can be adjusted by adjusting the inclination of the wind direction guide when the hot air is blown out and when the radiant heat is emitted, and both of them can be adjusted in the bathroom. Can be directed to the washing area. Further, when radiating heat is radiated, radiation efficiency can be improved by tilting the entire wind direction guide in a straight section and tilting in the radiating heat radiation direction. In addition, the apparatus can be made compact by allowing generation of warm air only with a far-infrared quartz heater.
