Description

Flat Case Hot Water Unit {FLAT CASING WATER-HEATER}

The present invention relates to a hot water device comprising a water tank and means for heating the water.

The present invention relates to a domestic hot water device.

Conventional hot water devices are cylindrical, which has taken up quite a lot of space.

However, US 4551612 describes a water heater having a flat shape. This hot water device has a flat, parallel hexagonal shape. In order to withstand the pressure of the water contained in the hot water device, crenellation is formed on the inner sidewall. The water heater is provided with a plurality of resistors arranged in the direction perpendicular to the gun and at various heights.

In such a device, the amount of water that can be heated is small because the side walls formed by the gun must not be placed too far apart to withstand pressure.

GB 731.769 discloses a flat water heater with a vertical compartment, a compartment for receiving resistance and a means for collecting hot water. Due to this structure, the device causes thermal imbalance, and the compartments are not heated to the same temperature at which water movement is limited.

DE 4012203 discloses a water heater comprising a cylindrical compartment and a resistor located in the lower part. Such water heaters have a number of disadvantages, such as the significant heat loss between the compartments due to the shape of the water heater. In addition, this shape reduces the capacity of water that can be stored in the water heater. After all, the water heater must be connected with hot water and cold water in the upper part of the water heater. If pipes are misplaced, plumbing repairs must be made.

The present invention includes a water tank and heating means; The tank has a series of conduits arranged in parallel, with a major end of the conduit running into a common water collection, a minor end of the conduit running with a common water heating, and the conduit having a rectangular cross section. Wherein said common water heater is capable of receiving heating means arranged in a direction perpendicular to said conduit; By proposing a hot water device, the above problems are solved in whole or in part.

An advantage of the present invention is that the hot water device is capable of heating and storing a large amount of water, and at the same time is configured in a flat parallelepiped shape.

In fact, the internal structure consists of conduits arranged in parallel and arranged in parallel, the conduits leading to a common hot water collection, which improves the capacity of the device to withstand water pressure and improves water mobility. Thereby improving the convection that takes place within the device.

In a particular embodiment, the separated and parallelly arranged conduits run from a common end of the conduit to a common water heating.

Another advantage of the device according to the invention is that the cross section of the conduit is rectangular. Thus, rectangular cross-section conduits are arranged in parallel, and this structure greatly limits heat loss between the conduits. In addition, the rectangular cross section of the conduit is optimal for the device to contain a larger volume of water in a predefined space.

By placing the heating means in a vertical direction with respect to the conduit, it is possible to improve the convection of water inside the hot water device, thereby improving the efficiency of the hot water device.

In addition, an outer sidewall of one or more common portions preferably overlaps the outer sidewall surrounding the conduit. This structure can help increase the capacity of the device to withstand hydraulic pressure.

The two common portions are formed with one or more removable orifices for receiving the heating means.

Another advantage of the present invention is that the device can be used in a variety of locations to suit accidental external conditions. The device can be rotated by 180 ° or 90 °.

Other objects and advantages will be apparent from the following description of the preferred but non-limiting examples.

First, the present invention is a hot water device comprising a water tank and heating means, wherein the tank is composed of multiple conduits that are separated and adjacent, and the main end of the conduit is connected to a common part for collecting hot water. Remember that it is a hot water device.

According to another preferred embodiment of the invention, the hot water device is:

The secondary end of the vertical conduit leads to a common water heating,

The common water heater and the common hot water collector can receive heating means arranged perpendicular to the conduit,
