Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating type circulating means for circulating air so as to heat air sucked from a bathroom and return it to the bathroom as drying air while sucking and discharging air from the bathroom. And a control means for controlling the operation of the circulation means.

[0002]

2. Description of the Related Art The above-mentioned bathroom dryer dries articles to be dried, such as laundry, existing in the bathroom, and absorbs moisture from the articles to be dried to increase the humidity inside the bathroom to the outside of the bathroom. While sucking and discharging the air, the air sucked from the bathroom is heated and returned to the bathroom as drying air. Conventionally, a wind direction guide means such as a louver is provided at an outlet of the drying air returned into the bathroom, and the direction of the louver or the like is manually adjusted so that the drying air is likely to be present in the bathroom. I was trying to blow out to the place.

[0003]

However, conventionally, after the direction of the louver or the like is manually adjusted, the direction of blowing the drying air is fixed, so that the object to be dried at the place where the object to be dried is to be present is located. Of the dry matter, the dry matter at the position where the drying air hits is dried early after the start of drying, but the drying air is continuously applied. Drying air is not always used properly for drying the object to be dried so that it does not dry. As a result, the drying efficiency is reduced, and the time required to dry the entire object to be dried is longer. And the consumption of fuel such as heating gas increases,
There was a problem that running cost was high. The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to use drying air appropriately for drying an object to be dried, thereby maximizing the drying efficiency, and thereby improving the conventional technology. The problem is to solve the problem.

[0004]

According to the first aspect of the present invention, in the bathroom dryer described at the beginning, there is provided a blowing direction changing means for changing a blowing direction of drying air returned into the bathroom by the circulating means. When the control unit is instructed to perform a drying operation for drying the object to be dried, the blowing direction is directed to a place where the object to be dried is expected to be present in the bathroom, and the blowing direction is changed over time. The blowout direction changing means is operated so as to change the airflow direction toward the place where the object to be dried is expected. Therefore, when the drying operation is instructed, the direction of the blowing of the drying air changes with time while being directed to the location where the object to be dried is located in the bathroom, and the direction of the air to be dried located at the location where the object is to be dried is located. Since the drying air hits the entire dried product, the drying object is fixed after manual adjustment of the blowing direction of the drying air. The drying air is used for drying the object to be dried, while the object to be dried is not easily dried, while the object to be dried is not easily dried while the object is continuously exposed to the drying air. As a result, the drying efficiency can be maximized as much as possible, thereby shortening the drying time for drying the entire object to be dried and reducing the running cost by reducing the fuel consumption of gas and the like. It is possible.

According to a second aspect, in the first aspect, the control means is configured to change the blowing direction by a set angle each time a set time elapses. Accordingly, the blowing direction of the drying air directed to the place where the object is to be dried is changed by the set angle every time the set time elapses, so that the whole object to be dried located at the place where the object is to be dried is dried. The blowing direction changing means is actuated so that the air to be blown is applied.For example, in the case where the blowing direction is continuously changed with the passage of time in an angle range including the place where the object to be dried is to be present, the blowing direction is changed. Compared to an increase in the operating energy of the changing means, the operating energy can be changed only intermittently by the set angle, and energy saving can be realized. Means are obtained. In addition, as described above, in the case where the blowing direction of the drying air is changed by a set angle every time the set time elapses,
The set time is preferably set to such a time that the object to be dried hit by the drying air within the time is sufficiently heated to dry well, and the set angle is the angle of the drying air at that angle. It is preferable to set the angle so that the drying air satisfactorily hits the object to be dried adjacent to the object to which the drying air has hit when the blowing direction is changed, and such setting time and setting By setting the angle, it is possible to surely and efficiently dry the entirety of the object to be dried while properly drying each part of the object to be dried located at the location where the object to be dried is present without leakage.

Therefore, the object to be dried is held by the holder provided at the location where the object to be dried is to be provided, and the object to be dried is predetermined with respect to the drying air whose blowing direction changes in a state facing the location where the object to be dried is to be located. Since it is maintained in a state that satisfies a favorable positional relationship, it is possible to perform an appropriate drying operation only by holding the object to be dried on the holder, and thus, it is preferable to set forth in claim 1 or 2 Means can be obtained.

According to a fourth aspect, in the third aspect, a plurality of the holders are provided so as to be spaced apart in the horizontal direction. Therefore, since the object to be dried is held by the plurality of holders provided at the place where the object to be dried exists at a predetermined interval in the horizontal direction, even if the object to be dried is relatively large, The object can be positioned at the place where the object to be dried is to be located, and can be appropriately dried, whereby the preferable means of claim 3 is obtained.

According to a fifth aspect, in any one of the first to fourth aspects, the control means directs the blowing direction to the center of the place where the object to be dried is to be located as time elapses. A reference state, and one end side state changed from the reference state to one end side of the place where the object to be dried is to be present,
The one end side of the place where the object to be dried is present is sequentially changed from the reference state to the other end state which is turned to the other end side opposite to the one end side, and the time in the reference state is changed to the one end side state. And a time longer than a certain time in each of the other end states. Therefore, first, the blowing direction of the drying air is directed to one end of the place where the object to be dried is to be located, and the other end to the side opposite to the one end of the place where the object to be dried is to be located. For a time longer than a certain time in each of the states, it is operated to the reference state facing the center of the place where the object to be dried is to be present, and then the one end state and the other end state are sequentially shorter than the reference state time. Since it is operated for a long time, after drying most of the objects to be dried existing in the place where the object to be dried is to be dried, the object to be dried located at the end of the area where the object to be dried is low in dryness is dried. Thus, the whole of the object to be dried can be appropriately dried, whereby the preferable means according to any one of claims 1 to 4 can be obtained.

According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the control means is configured to be able to change and set the blowing direction toward the location where the object to be dried is expected to exist. Therefore, even when the position of the location where the object to be dried is to be changed variously in the bathroom due to the installation conditions of the bathroom dryer, the convenience of the user, and the like, the drying is performed toward the changed location where the object to be dried is to be located. By changing the blowing direction so that air is blown out, the object to be dried at the place where the object to be dried is to be dried can be appropriately dried, whereby the suitable means according to any one of claims 1 to 5 can be obtained. Can be

According to a seventh aspect of the present invention, in the fifth aspect, the control means is directed to a center of the place where the object to be dried is present, as the blowing direction that is changed in a state of being directed to the place where the object is to be dried. The reference direction, one end direction facing the one end side of the to-be-dried object existence place, and the other end side direction facing the other end side opposite to the one end side of the to-be-dried object existence place are changed. It is configured freely. Therefore,
Even in the case where the location and size of the place to be dried in the bathroom changes variously due to the installation conditions of the bathroom dryer, the convenience of the user, and the like, the entirety of the place to be dried may be changed. By changing the blowing direction so that the drying air is blown out, the object to be dried at the place where the object to be dried is to be dried can be appropriately dried, whereby the preferable means of claim 5 can be obtained.

According to an eighth aspect, in the sixth or seventh aspect, there is provided a blowing direction storage means for storing information of the changed and set blowing direction, and the control means stores the information in the blowing direction storing means. Based on the information,
It is configured to operate the blowing direction changing means. Therefore, once the blowing direction of the drying air is changed, the blowing direction information is stored, and in the next drying operation, the blowing direction changing means is operated using the stored blowing direction information. ,
7. When the drying operation is performed under the same condition of the place where the object to be dried is present, it is not necessary to set the blowing direction each time, and the operability can be improved.
Or 7 suitable means are obtained.

Specifically, the heating / drying machine control unit A3 changes the blowing direction by a set angle every time a set time elapses, that is, the blowing direction is changed with the lapse of time in accordance with the lapse of time.
A reference state (position a) toward the center of the object, one end state (position b) changed from the reference state to one end side of the place 14 where the object to be dried is to be located, and the object to be dried from the reference state. Sequentially changing to the other end state (position c) in which the direction is changed to the other end side opposite to the one end side of the expected existence place 14,
In addition, the time in the reference state is set to be longer than the time in each of the one end state and the other end state.

As a result, in the drying operation mode, FIG.
As shown in (b), after the drying air blown downward from the blowout port 4 passes through the drying target D at the drying target existence place 14, the drying air changes its direction in the horizontal direction (left direction in the drawing). ,
Next, an air flow is formed that reverses upward and heads toward the suction port 3. Then, by changing the blowing direction from the outlet 4 in the order of the positions a, b, and c, the drying air directed to the position a first causes the drying target D at the target drying object expected location 14 to be dried. After most have been dried,
The undried portions of the object to be dried D located at both ends of the to-be-existing object to be dried location 14 are dried, and the entire object to be dried D is efficiently dried in a short time. Incidentally, FIG. 8 shows that the drying time T when the blowing direction from the blowing port 4 is fixed at the position a is longer than the drying time (Ta + Tb + Tc) when the blowing direction is changed as described above. It is shown.

The installation location 14 of the object to be dried, that is, the installation position of the holder 30 is set to be substantially immediately below the outlet 4 under standard conditions (see FIGS. 5 and 7). The position may be changed from the above standard position depending on conditions at the time of actually installing the bathroom dryer, convenience of the user, and the like. Therefore, the to-be-dried object existence place 14
In order to respond to the change, the direction of the air blow from the air outlet 4 can be changed and set. Specifically, in the drying operation mode, if the louver switch 28 is kept pressed, the direction of the movable louver 13 is changed, the blowing direction from the outlet 4 changes slowly, and the louver switch 28 is not pressed. And movable louver 1
3 stops changing the direction and the movable louver 13 at that time
Is detected by a detection volume (not shown), and the detected angle data is stored in a memory 29 (see FIG. 9, which is connected to the heater / dryer controller A3 as the data of the position a). Non-volatile EEPRO
M) (see FIG. 11B).
(B) As shown in FIG.
The louver switch 28 is operated so that the angle data of the movable louver 13 is stored so as to face the intermediate position of 0. Thereafter, the direction of the movable louver 13 is
The angle of the stored a position, the angle of the b position changed by θ1 with respect to the angle of the stored a position, and the c position changed by θ2 with respect to the stored angle of the a position And the angle is sequentially changed.

From the above, the heating dryer control unit A3 is
The direction of the blowing toward the location 14 where the object is to be dried is configured to be freely changeable, and information on the changed and set blowing direction (specifically, the angle of the movable louver 13 corresponding to the position a) Data) is constituted by the memory 29, and the heating / drying machine control unit A3 is provided with the memory 29.
Is configured to operate the blowing direction changing means 9 based on the stored information.

[Another Embodiment] In the above embodiment,
The blowing direction from the blowing port 4 is defined as the a position, the b position,
In the case where the position is changed in the order of the c-position, the configuration is such that only one cycle is executed. For example, as shown in FIG.
After executing one cycle of a1, Tb1, and Tc1, a total of two cycles of one cycle of Ta2, Tb2, and Tc2 may be executed. In this case, each time Ta2, Tb2, Tc2 in the second cycle is set to be shorter than each time Ta1, Tb1, Tc1 in the first cycle.

In the above embodiment, when the direction of the drying air blowing toward the object-to-be-dried object location 14 is changed and set, the movable louver corresponding to the position a facing the center of the object-to-be-dried object existence place 14. 13 is changed and stored only, and the angle of the movable louver 13 is changed by the previously set θ1 and θ2 to the left and right around the stored angle of the position a. In addition, angle data for changing the angles of θ1 and θ2 may be stored together with the angle of the position a. That is, in this case, the heating / drying machine control unit A3 changes the state in which the heating / dryer control unit A3 faces the object-to-be-dried object planned place 14, and the reference direction toward the center of the object-to-be-dried place 14; The one end direction facing the one end side of the object-to-be-dried object existence place 14 and the other end direction facing the other end side opposite to the one end side of the object-to-be-dried object existence place 14 can be changed and set freely. At the same time, the information of each changed blowing direction is stored in the memory 29, and the heating / drying machine controller A3 activates the blowing direction changing means 9 based on the stored information in the memory 29. It is configured as follows.

More specifically, as shown in FIG. 13, a central storage switch 33a and a left storage switch 33 are provided on the remote controller A2 for the dryer and heater in addition to the louver switch 28.
b, a right storage switch 33c is provided. Then, in the drying operation mode, when the louver switch 28 is operated and the central storage switch 33a is pressed while the blowing direction is directed to the reference direction, the louver switch 28 corresponds to the reference direction detected by a detection volume (not shown). The angle data of the movable louver 13 is stored in the memory 29. Similarly, when the louver switch 28 is operated and the left storage switch 33b is pressed in a state where the blowing direction is directed to the one end side direction, the angle of the movable louver 13 corresponding to the one end side direction is detected. When the angle data is stored and the right storage switch 33c is pressed in a state where the blowing direction is directed to the other end side direction, the angle of the movable louver 13 corresponding to the other end side direction is detected, and the angle data is obtained. It is memorized. Thereafter, the direction of the movable louver 13 is controlled so as to be sequentially changed to the reference direction in which the angle data is stored, the one end direction, and the other end direction. In addition, when each of the reference direction, one end side direction, and the other end side direction as the blowing direction to be changed in a state facing the object to be dried place 14 is configured to be freely changeable, as described above, Instead of storing the angle data of the movable louver 13 corresponding to each direction of the reference direction, one end direction, and the other end direction, the angle data of the movable louver 13 corresponding to the reference direction, and swinging the left and right sides with the center as the center. The angle data corresponding to the swing angles θ1 and θ2 to be set may be stored.

In the above embodiment, the blowing direction at the position a is set to be an intermediate position between the two holders 30. For example, when the number of the holders 30 is one, the blowing direction at the position a is changed. The position is set so as to face the one holder 30. In addition, in the case of this one holder 30, the range of the to-be-dried object existence place 14 is two holders 3
Since it becomes narrower than the case of 0, the position b is changed from the position a to the one end of the object-to-be-dried expected location 14 by the angle θ1, and from the position a to the other end of the object-to-be-dried expected location 14. In the setting of the b position changed in the direction of the angle θ2, the values of the angles θ1 and θ2 are set to smaller angles as compared with the case of the two holders 30.

FIGS. 14 and 15 show another embodiment in which the direction of blowing from the blowing port 4 is changed.
In this embodiment, the drying object scheduled place 14 is set so as to be located below the blowout port 4, and the heating / drying machine control unit A <b> 3
With the passage of time, the blowing direction of the drying air blown downward from is gradually changed from a state facing a side far from the suction port 3 in the place 14 where the object to be dried is present to a state facing a side closer to the suction port 3. It is configured as follows. That is, position a ′, position b ′, and position c ′ in this order.
At Ta 'time, Tb' time at position b ', T at position c'
The blowing direction is changed so as to be maintained for c 'time.

Thus, the drying air blown downward from the drying air outlet 4 provided on the ceiling side toward the object-to-be-dried place 14 located therebelow is supplied to the outlet 4.

For example, a configuration may be adopted in which a blow-out tube that blows out drying air that is returned into the bathroom C is provided in the blow-out port 4 in a freely changeable direction, and the direction of the blow-out tube is changed by an actuator. Further, in the above embodiment, the blowing direction changing means 9 changes the blowing direction of the air along the direction intersecting with the elongated blowing port 4. The direction of the blow-out cylinder toward the expected existence location 14 may be changed by rotating the direction of the blow-out cylinder so as to draw a circle around the axis toward the expected object existence location 14.

In the above embodiment, the control means A3
However, in the case where the blowing direction of the drying air is changed in a state facing the object-to-be-dried location 14 with time, the blowing direction is changed by a set angle every time a set time elapses. However, besides this, the blowing direction may be continuously changed with the passage of time in an angle range including the location 14 where the object to be dried is expected to exist. Also, in the case where the blowing direction is changed by a set angle every time a set time elapses, as in the above embodiment,
Ta time at position a (or Ta 'time at a' position),
Tb time at position b (or Tb 'time at b' position),
The blowout angle is not limited to maintaining the blowout angle at the c position for the Tc time (or the Tc 'time at the c' position), but the angle change amount and time setting can be changed as appropriate according to the situation.

In the above-mentioned embodiment, the drying air outlet 4 is provided on the ceiling side of the bathroom C, and the drying object air is blown downward by setting the place 14 where the object to be dried is to be set below. However, in addition to this, the place 1
For 4, an outlet may be provided on the side wall of the bathroom C so that the drying air is blown out sideways. In this case, a suction port and a discharge port are provided on a horizontal wall, for example, in a state where the discharge port is located on the upper side and the suction port is located on the lower side and are spaced apart in the vertical direction, and the drying port blown sideways from the discharge port. An air flow can be formed and dried efficiently so that the air returns to the suction port after passing through the object-to-be-dried place 14.

In the above-described embodiment, the holder 30 for holding the object to be dried is constituted by a so-called clothes-drying bar.
