Abstract

An electric hot water apparatus placed with a screw pipe inside is provided to improve the small electric boiler performance by rotating the water discharged from the carbon tube heater by a circulation pump and circulating the water by a storage container. An electric hot water apparatus placed with a screw pipe inside using a carbon heater is composed of a screw pipe mounted in a carbon heating heater; a partition attached with a hole where water is inlet at the upper end of the silica glass pipe; another partition attached at the lower end with a hole where the hot water is discharged; a power lead socket mounted at both ends of the carbon heating heater to heat the carbon heating heater; and a controller controlling the power supply of the power lead socket. The screw pipe is separated with a predetermined interval to a predetermined height at the upper end, and an inlet pipe(105) is connected to the penetrated pipe at the lower end. A partition is formed at the screw pipe with an outlet pipe(106) where the heated hot water is discharged.

The present invention relates to an invention that can improve the performance of the water heater and boiler by using a carbon tube heater with a built-in screw tube. Conventional water heaters need a lot of electricity because a common heater is built to warm water when passing through the tube. As is well known, heat generated by conduction heats quickly only when the heat source and surface area are large. When the water heater is operated at the moment, since the water penetrates the pipe heated by the heater, the water capacity must be 5khw or more to use the hot water. Recently, the carbon heating element is coated with a thin film on a quartz tube rather than a conventional heater method, and power is applied from both sides to pass water through an empty pipe inside. However, this method also requires very high electric power compared to the flow rate because the surface area where water directly contacts the heat source is very small.

In order to overcome this disadvantage, the present invention has a spiral water screw tube mounted inside a tube coated with a carbon heat source to widen the surface area in which water contacts the heat source, and has high thermal conductivity due to vortex phenomena caused by screws. Will have In other words, if the surface area where water penetrates the existing pipe is in radius R, 2πR x H (height) or screw pipe inside increases by πR ^ 2 x N (screw rotation), so that water is heated. Not only does the surface area of contact increase, but also the contact time of the heater is long, and enough hot water can be supplied in a short time with little power.

In order to complete such an invention, the present invention is configured as follows. As shown in FIG. 1, a screw tube 201 is installed inside the carbon tube heater 100 coated with a conventional carbon heating element, and then an inlet tube 105 is mounted on the carbon tube heater 100. At the bottom, the outlet pipe 106 is mounted. At this time, the water introduced to the top penetrates the screw tube 201 by gravity light pressure, and the water is heated by heat generated outside the carbon tube heater due to the power applied to the carbon tube heater 100.

In another method, the upper end of the carbon tube heater 100 is sealed, and the pipe 202 wound inside the screw 201 is wound on the exterior, and the gravity or circulation pump pressurizes the water to the inside of the carbon tube heater 100. Raise up to the top of the through the screw tube 201 is discharged through the water outlet pipe 106 in the lower portion. At this time, the screw tube should be spaced apart from the upper partition so that the water 110 can penetrate.

The above method is aimed at minimizing heat loss and thermal shock.

At this time, the water 110 should be waterproofed to the outside of the carbon tube heater 102 so as not to contact the heating element (not shown) and the wire should be waterproofed. As a method of waterproofing, there is a method of installing a quartz glass tube on the outside of the carbon tube heater 102. In addition, the outside of the carbon tube heater 102 is wrapped with a heat insulating material (not shown) in order to increase thermal efficiency.

Carbon tube in which the screw tube is embedded by passing through the case for mounting the controller and the power supply to the carbon tube heater 200 with the screw tube and the water inlet and outlet pipe formed on one side of the case When the respective water supply pipes are connected to the inlet pipe 105 and the outlet pipe 106 of the heater, the water heater is instantaneous.

At this time, if a plurality of carbon tube heaters with a built-in screw tube are disposed, they can be used as instant electric water heaters even though water continuously passes at a high flow rate.

As an effect of the present invention, it is possible to build an instantaneous water heater and electric boiler which can operate at a lower power than conventional electric water heaters or boilers by increasing the thermal efficiency. Electric water heater can be used comfortably and silently without any equipment.

In addition, the conventional water heater requires a storage device, but if the present invention is used, it can be used without a separate storage device, thereby increasing the utilization of space.

When the water discharged from the carbon tube heater in which the screw tube is embedded is rotated by a circulation pump and circulated to a storage container, a small electric boiler is formed.
