Detailed description

The following is a description of the present invention, including a detailed description of various aspects of the present invention, as well as a description of its advantages over known devices.

The following is a detailed description of some of the terms of the present invention.

The terms "apparatus for producing water" or "apparatus for producing hot water", which may be used interchangeably, in the meaning used in this description, should be understood as a heating element or heating apparatus, or means for heating, containing (s) container or a water chamber with a water inlet and a hot water outlet. The supply and volume of hot water can be controlled by the inlet of cold water to the water producing apparatus, the outlet may preferably contain control means and thus the outlet of hot water can be adjusted, and / or the outlet of hot water can be adjusted in accordance with the inlet of cold water.

The terms "quick hot water" or "quick water", which can be used interchangeably, as used in this description, should be understood as hot water that can be produced on demand in a very short period of time, and does not require long preparation time of the system before receiving it; in addition, in the case of “quick hot water” as implied in this description, no storage or receptacle is required in which hot water is prepared in a certain amount, which limits the amount of hot water used or ready to use. The production of "quickly obtained hot water", in contrast to the production of hot water in batches, as in the known devices, on the contrary, will be carried out on demand and continuously.

As used herein, the terms "hot water on demand" or "water on demand", which may be used interchangeably, are to be understood as hot water that can be used immediately after it is produced in an apparatus for producing hot water, and the production of hot water can be continuous, whereby water or any other liquid, or water containing other liquids or additives, is supplied to the water production apparatus at the water inlet and discharged from the apparatus through its outlet.

The term "pressure" as used in this description refers to the pressure generated by the pump or injection means in the range of about 5 bar (0.5 MPa) to about 20 bar (2 MPa), and which can be adjusted and matched with a different apparatus or other process conditions.

The term "desired temperature" as used in this description can refer to the temperature of the heating means or the temperature of hot water obtained by the apparatus for producing hot water. The required temperature can range from about 20 ° C to 250 ° C.

The term "water receptacle" or "water chamber" as used herein, refers to a vessel and volume associated with or surrounding the heating means, or forming part of the heating means. This volume can range from about 2 ml to 200 ml, or from 5 ml to 50 ml, or from 5 ml to 10 ml.

The term "heating time" in the meaning used in this description means the time it takes to reach the required temperature, for example, a vessel, a target liquid such as water, a heating agent, this time can be less than 10 seconds, or less than 5 seconds. , or from 10 s to 20 s, or from 5 s to 10 s, or from 0.5 s to 5 s, or from 1 s to 3 s.

In one aspect, the present invention relates to an apparatus for rapidly producing hot water, comprising: (i) heating means, (ii) pumping means, (iii) control means that controls the pumping means and heating means, the means the controls are configured to change the temperature of the heating means when the pressure of the pumping means changes.

One of the advantages of the apparatus of the present invention is that hot water can be provided a short time after turning on said apparatus, and the user does not need to wait as long as when using known hot water apparatus.

Another advantage of the present invention is that there is no need for a hot water storage device. A hot water accumulator such as described in prior art is either a receptacle located downstream of a hot water generating unit (eg a heating element) or a receptacle containing a hot water producing element and thereby serving as a hot water accumulator. From this element, hot water is discharged through an outlet or through a valve. One of the drawbacks of the known apparatus for producing hot water is that it takes a relatively long time for this apparatus to become ready to discharge hot water. Another disadvantage is the limited amount of hot water, which may be available for some time for use, that is, as soon as the hot water contained in this hot water storage tank is used up, or the water contained in this storage tank is used, the said storage tank must be reused. fill with water and reheat the water, which again takes some time until the appliance is ready to dispense hot water. On the other hand, in the case where water is continuously supplied to the accumulator that includes the heating means, it is difficult to control and regulate the temperature of the hot water. A situation is possible when the required temperature of hot water is not reached, and hot water with a temperature below the required one will be discharged. Therefore, the known apparatus for producing hot water imply a long waiting period after being switched on or during use.

An advantage of the apparatus of the present invention is that, unlike the prior art apparatus, it can provide hot water very quickly after being switched on. The appliance only needs a very short time to release hot water; accordingly, the advantage of the apparatus of the present invention is the minimum waiting time before hot water is available. In addition, when it is used, there is no need to wait for hot water to be ready every time the water tank needs to be refilled. In addition, the possibility of precise control of the required temperature and the desired temperature of hot water is realized.

From the point of view of construction and execution, the present invention also has advantages, since compared to the known devices for producing hot water, it requires fewer components or components that are smaller in size. Accordingly, the devices can be made in different ways and in many cases have smaller dimensions, which is an advantage and also implies a reduction in costs.

An advantage of one embodiment of the present invention is that the hot water producing apparatus is configured to dispense hot water without long waiting times when using such an apparatus. It is also an advantage of such an apparatus for producing hot water of the present invention, in general, to maintain a fixed or adjustable, preset or desired temperature of the heating element.

The main idea and one of the aspects of the present invention is that at the beginning of the process a special pump fills a container with water (for example, from 10 ml to 20 ml). The fast-acting heating element is adjusted until the required temperature is reached, which is 200 ° C, while the pressure does not exceed 15 bar (1.5 MPa); these target parameters are obtained in less than 5 seconds, for example, from 0.5 seconds to 3 seconds. At this point, the system is ready to dispense hot water. Hot water is discharged from the heating / water / hot water chamber by means of an adjustable device, while the hot water is discharged through, for example, a heating element outlet or through a valve.

During operation of the device and continuous operation of the process, the heating element is adjusted to reach or maintain a specific desired temperature (eg, 250 ° C). The system is ready to dispense hot water. This system is designed so as to simultaneously release hot water through an adjustable device and fill the container with cold water with a special pump with an adjustable specific capacity.

Hot water is discharged through the outlet of the heating element. When discharging hot water, the performance of the special pump is adjusted taking into account the temperature of the fast-acting heating element in such a way as to maintain an optimal ratio between the performance of the special pump and the temperature level of this fast-acting heating element.

The apparatus of the present invention may also comprise a water reservoir, a rotation sensor for the pumping means, a capacity measuring means, a temperature measuring means in the heating means, a pressure measuring means, a water container for the heating means, a cold water inlet, and an outlet for hot water on the heating means and / or an additional water circuit passing through the container for the heating means, while said apparatus does not have an additional container for hot water.

Other parameters can also be maintained at the required values, and these other characteristics and parameters will be adjusted to obtain hot water. Thus, the control unit (9) provides general control of various parameters.

The apparatus may also include an additional water circuit passing through the heating agent receptacle.
