Description

[Detailed description of the invention] This invention consists of a heating water heating machine with a multi-stage combustion chamber of the water heating furnace, and a drying chamber that utilizes the exhaust air from the water heating furnace placed on top of it. This relates to a dryer.

Conventionally, small-sized water heaters for home or commercial use have generally been vertical boiler types, which are widely used for hot water in baths or for space heating, but they have poor thermal efficiency and exhaust gas is dissipated into the atmosphere through the chimney. This was a huge waste of energy.

Therefore, this idea was developed to save energy by configuring the combustion chamber of the water heating furnace in multiple stages to improve thermal efficiency, and placing the drying chamber on top of the combustion chamber. This is a dryer with a multi-stage heating water heater that is equipped with a moisture separator and a blower to keep the drying chamber dry at all times, making it ideal for the energy-saving era. It is.

An embodiment of the present invention will be described below based on the drawings.
The combustion chamber is divided into multiple stages such as 5A, 5B, and 5C by dividing it by several stages of water canopies 3a, 3b, 3c or water pipes 4, etc., and a water supply valve 6 is provided at the lower part of the water supply heating furnace 2.
A drying chamber 9 consisting of a heat insulating material 8 on the outside is placed on top of a water heater with a water intake valve 7 attached to the top,
Further, around it, there is an exhaust mantle 10 of the water supply heating furnace 2.
A chimney 11 is provided at the top of the drying chamber 9.
A moisture separator 12 and a blower 13 are installed outside the drying chamber 9.
It is made by communicating with

In the drawing, R is a flame reflector, E ₁ , E ₂ ,
E ₃ etc. are flame passages, H is an auxiliary heater, G is a pressure gauge, and D is an opening/closing door of the drying chamber 9.

Next, to explain the operation of the present invention, when the combustor 1 is ignited, the flame hits the flame reflection plate and rises while heating the combustion chamber 5A, passes through the flame passage _E1 , and heats the combustion chamber 5A. The flame rises upon hitting the flame reflector plate R, enters the combustion chamber 5B through the flame passage _E1 , and further rises from the passage _E2 and enters the combustion chamber 5C. During this time, the water canopies 3a, 3b, 3c, water pipe 4, etc. are heated to change the cold water inside to hot water, and hot water is taken out from the water intake valve 7 as necessary.

The hot air rising from the passage _E3 enters the exhaust mantle 10 provided around the drying chamber 9, heats the drying chamber 9, and is radiated to the atmosphere from the chimney 11 at the top.

In addition, water vapor generated from items to be dried, such as laundry stored in the drying room 9, enters the glass moisture separator 12 from the upper pipe 14, where the water is removed and dried air is sent from the lower pipe 15 by the blower 13. It is refluxed to the drying chamber 9.

As explained above, according to the present invention, the combustion chamber of the water supply heating furnace is configured in multiple stages to improve thermal efficiency, and a drying chamber for combined use is placed on top of the combustion chamber, and the exhaust air of the water supply heating furnace is utilized to further wash laundry. It can be used for drying things, etc., and is equipped with a moisture separator and a blower to keep the drying chamber dry at all times. Usually, the temperature of the hot water reaches 50 to 60 degrees Celsius and dries within about 15 minutes after igniting the combustor. Indoor temperature
It is a dryer combined with a heating water heater that can obtain a temperature of 70 to 80°C, can be widely used for home or commercial use, and exhibits excellent performance such as particularly high thermal efficiency.
