DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a drying room utilizing the residual heat of various water heaters.

[0002]

2. Description of the Related Art In recent years, the number of cases where washing is performed in the evening to night has been increasing in accordance with a change in lifestyle, and a method for efficiently drying the washed clothes indoors has been demanded. On the other hand, there is a demand for a method of drying clothes indoors efficiently in a room, mainly in apartment buildings, from the viewpoint of urban beauty in drying clothes during the day.

[0003] In order to meet such requirements, indoor drying methods include (1) heating a drum using electric power and drying clothes inside the drum, and (2) providing a simple small space in a room. Put a hot air blower using electric power in it, raise the temperature of the small space, and dry the clothes. (3) Install a hot air blower using electric power on the ceiling of the bathroom to reduce the temperature of the bathroom. Elevating to dry clothes.

[0004] However, these methods have the following problems.

(1) The amount of power required for drying is large, and the running cost is large.

[0006] The finished state is poor as compared with the one hung on a clothesline.

[0007] The amount that can be dried at one time is small.

(2) Since the humidity in the small space increases during drying and the drying efficiency decreases, the amount of power required for drying is large and the running cost is large.

The indoor humidity increases.

[0010] The amount that can be dried at one time is small.

[0011] It takes time to install a small space.

(3) Since it takes time to reach a predetermined temperature and humidity in the space, the amount of power required for drying is large and the running cost is large.

[0013]

The problem to be solved by the present invention is that there is no need to use a special living space,
It is possible to dry laundry and other items in a short time while keeping the energy input to drying low.
That is, it is to obtain a drying room with high drying efficiency at home.

[0014]

SUMMARY OF THE INVENTION In the present invention, a place where a water heater which is widely used for cooking, washing or bathing in a home in recent years is installed in a living space in another home. Was completed in a location where it was installed in an unrelated place, generating a considerable amount of residual heat, and the surrounding area was secured for safety.

In particular, an electric water heater using nighttime electric power has a large storage water amount, a large surface area for radiating residual heat, is excellent in safety, and has a large arrangement space to secure a space as a drying room. Cheap.

According to the present invention, in order to obtain a drying chamber utilizing the residual heat of the water heater, the amount of heat insufficient during drying is supplemented by an auxiliary heater, thereby providing a drying chamber with high drying efficiency.

According to the present invention, in order to obtain a drying room for clothes and the like that makes effective use of the residual heat of a water heater that is constantly radiated, an auxiliary heater compensates for a shortage of heat to obtain a predetermined room temperature suitable for drying. In addition, in order to reduce the humidity in the room, intake and exhaust ports are provided in the closed space, and by controlling the amount of heat by this auxiliary heater and the amount of air flowing through the intake and exhaust ports, a drying chamber with good drying efficiency is provided. It was done.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION It is desirable to use a wall using a heat insulating material or a wall having a high heat insulating property as a wall forming a closed space in order to effectively use residual heat of a water heater.

The size, number, and position of the intake / exhaust ports are determined by the size of the drying chamber, the position of the water heater, and the like. It is desirable that the position of the vessel be opposed to the exhaust port, and the position of the exhaust port be opposed to the water heater when viewed on a plane above the ceiling or the side wall. It is desirable that the intake and exhaust be forcibly performed using a fan or the like in order to increase the efficiency.

As the auxiliary heater, a direct-radiation type or convection type heater using electric power, a heat exchanger using the heat of hot water in a water heater, or the like is used.

If the humidity in the drying chamber rises during drying, high-humidity air is exhausted from the exhaust port, and air with lower humidity is taken in from outside the drying chamber than from the room. Although the humidity to be set depends on the humidity of the outside air, the relative humidity is desirably 60% or less.

The temperature of the drying chamber is ON-OFF of the auxiliary heater.
In the case of a heater using electric power, the control is performed by turning on and off a heater power supply. However, in a heat exchanger using heat of hot water, the control is performed based on the presence or absence of a flow rate.

The temperature and humidity are preferably set at about 35 ° C. and about 40% to 60% (relative humidity) when the control is performed. However, when the humidity of the outside air is high, the temperature in the drying chamber is increased. That is, in controlling the temperature and the humidity, it is preferable to change the setting conditions of the temperature and the humidity depending on the season, and to control the operating conditions according to the setting conditions.

Considering the actual temperature control, an auxiliary heater using electric power is desirable because of its simplicity. Among them, from the viewpoint of safety, it is desirable to use a heater using a PTC element having a positive resistance characteristic that does not cause overheating of the heat source itself.

As for the structure of the auxiliary heater, in order to dry many clothes more efficiently, the radiator structure of the auxiliary heater has a planar shape and has a large area as much as possible. It is better to place it on a wall or the like and put the clothes near the auxiliary heater. Note that when a paint that emits far-infrared rays is applied to the surface of the auxiliary heater, the drying efficiency is improved.

As a heat source of the planar heater, a low temperature (70 ° C.) is considered from the viewpoint of safety in consideration of the possibility that a person touches the heat radiating surface.
It is preferable to use a PTC element having a positive resistance characteristic having a Curie point of about 90 ° C. and an aluminum heat sink from the viewpoint of heat dissipation.

Further, even if it is difficult to dry by providing a hook or the like on a heat radiating plate installed on the wall and hanging shoes or thick clothing on the heat sink, more efficient drying is possible.

Further, if the auxiliary heater using electric power can be made to use electric power at night as in the case of the water heater, and the drying is performed at night, the running cost can be further reduced.
