Abstract

PROBLEM TO BE SOLVED: To properly dry a bathroom after taking a bath by deciding that the bathroom needs to be dried after it is detected that a set time elapses as the water level of a bathtub remains constant. SOLUTION: A heat source machine control part B3 has a deciding means B5 for deciding a state in which a bathroom needs to be dried after taking a bath based on the detected result of a water level sensor 40. When the water level sensor 40 detects that the water level of a bathtub is constant and the lapse of of time of a timer reaches a setting time or more, the deciding means B5 decides that the bathroom C is in a state in which the bathroom needs to be dried after taking a bath, and the heat source machine control part B3 outputs to a drying and heating machine control part A2 a water level constant signal G showing the constant water level of the bathtub. When the water level constant signal G is inputted to the drying and heating machine control part A2 from the heat source machine control part B3, the control part A2 starts a drying operation for drying and operating a bathroom drying means A. Thus, the operation start means of the bath room dryer is devised, so that its facility can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom drier for drying a bathroom to prevent the occurrence of mold and the like.

[0002]

2. Description of the Related Art A conventional bathroom drying apparatus is provided with an operation switch for instructing the start of operation by manual operation, and when bathing is completed, the operation switch is manually operated as necessary to start operation of the bathroom drying apparatus. It is configured to be.

[0003]

For this reason, the operation of the operation switch may be forgotten or troublesome and neglected, and the bathroom dryer may not operate properly. Due to the necessity of being neglected or neglected, it is necessary to check again whether or not the bathroom drying apparatus is operating properly.

The present invention has been made in view of the above circumstances, and has as its object to improve the usability by devising a means for starting operation of a bathroom dryer.

[0005]

According to the first aspect of the present invention, there is provided a judging means for judging a necessary drying state of a bathroom after bathing, and a judgment result by the judging means that the state is a drying necessary state. Control means for starting the drying operation of the bathroom drying means is provided, and when the determination means detects that a set time has elapsed while the water level of the bathtub provided in the bathroom is constant, it is determined that the drying is required. It is configured as follows. In other words, during bathing, for example, bathing in hot water in the bathtub, or drawing out hot water for body washing, etc., changes the water level in the bathtub, but when the bathing ends,
Since the water level in the bathtub does not change, it is considered that bathing has been completed when the set time has elapsed while the water level in the bathtub is constant. Therefore, by detecting that the set time has elapsed while the water level in the bathtub is kept constant, the determining means for determining the need for drying the bathroom determines that the drying is required, and the control means performs the drying operation of the bathroom drying means. Since the start is performed, the bathroom drying apparatus can be appropriately operated after the bathing is completed. When the water level in the bathtub drops and the water level falls below the set water level, it can be determined that the bathing has been completed.However, for example, the bathtub water may be used the next day, and the bathtub water may not necessarily be used after bathing. It is not always the case that the bath is dried, and it may not be possible to operate the bathroom drying device properly after bathing. However, if it is determined that bathing has been completed due to the lapse of the set time while the water level in the bathtub remains constant, the bathroom drying apparatus can be properly operated after bathing without such inconvenience.

According to the second aspect of the present invention, a water level sensor for detecting the water level of the bathtub is provided, and the determining means is configured to detect the water level of the bathtub based on the detection information of the water level sensor. It is. For example, as to whether or not the water level in the bathtub is kept constant, it is considered that if the appropriate amount keep operation was not performed and the appropriate amount keep operation was not performed, no hot water was drawn out by bathing and the water level did not decrease. . Therefore, it is possible to detect the water level in the bathtub depending on whether or not the appropriate amount of keep operation has been performed. However, since the water level sensor directly detects the water level in the bathtub, the water level is reliably detected. Further, in a bathroom drying apparatus having an automatic hot water function, a water level sensor for detecting the water level of the bathtub is usually provided, and this water level sensor can be used as well, without complicating the configuration. It is also effective in terms of cost.

According to the third aspect of the present invention, the bathroom drying means includes ventilation means for discharging air in the bathroom to the outside of the bathroom. Therefore, the humid air in the bathroom can be positively discharged to the outside of the bathroom to promote the drying thereof.

According to the fourth aspect of the present invention, the bathroom drying unit includes a heating unit for heating air in the bathroom. Therefore, the moisture in the bathroom can be positively evaporated by the heated air, and the drying can be promoted. Particularly, in the case where the bathroom drying means includes the ventilation means according to claim 3,
While actively releasing the moist air in the bathroom outside the bathroom,
Can be warmed.

According to the fifth aspect of the present invention, the heating means is provided in the bathroom air circulation path including a circulation fan for introducing air in the bathroom and returning the air to the bathroom. Therefore, the water in the bathroom can be positively evaporated by the heated air circulating in the bathroom, and when the temperature in the bathroom is low, such as in winter, the heating means is effectively utilized to make use of the heating means. Can also be heated.

Is operated, the ventilation operation ends.

In the cool air operation mode, as shown in FIG. 3, the movable damper 54 is moved to a position where a part of the air introduced into the bathroom air circulation passage 52 is discharged from the exhaust duct 53 to the outside. By driving the circulating fan 51 to drive the cooling fan, a cool air operation in which the bathroom air is circulated without being heated by the drying and heating heat exchanger 27 is started, and the set time set by the operation time setting unit 65 is counted up. Then, or when the operation stop switch 60 is operated, the ventilation operation is stopped by stopping the driving of the circulation fan 51, and the cool air operation is ended.

In the drying operation mode, the drying operation is started by the same start operation as the preliminary heating operation mode, and a part of the air introduced into the bathroom air circulation path 52 is discharged from the exhaust duct 53 to the outside and the remaining air is discharged. Is heated in the drying and heating heat exchanger 27 and returned to the bathroom C, and the thermal valve is opened and closed so that the temperature in the bathroom C is maintained within a preset temperature range for bathroom drying. Is controlled, and when the set time set in the operation time setting unit 65 is up, or
When the operation stop switch 60 is operated, the drying operation ends.

The automatic drying operation mode is executed when the automatic drying operation switch 66 is turned ON. In this automatic drying operation mode, the drying and heating unit control unit A2
Starts the drying operation of the bathroom drying unit based on the result of the determination by the above-described determination unit B5 that the drying is required.

Then, as shown in the flow chart of the automatic drying operation mode in FIG. 8, the drying required state is determined, and when the constant water level signal G is input from the heat source unit control section B3 (# 3).
1) A drying operation for drying the bathroom drying means is started by the same starting operation as in the above-described drying operation mode (# 32),
