Description

Water storage type water heater capable of fully utilizing hot water

Technical Field

The invention relates to the field of household appliances, in particular to a water storage type electric water heater.

Background

When the existing water storage type electric water heater is used, hot water is discharged and cold water is injected at the same time, and the pressure of tap water is utilized to inject the cold water into the water storage container to extrude the hot water. Therefore, the original hot water is gradually mixed into the cold water to be neutralized and cooled. The water in the whole liner is cooled by only using a small part of water, and the utilization rate of the hot water is extremely low. In order to meet the requirement of normal bathing time, the volume of the water heater can be increased only to prolong the time of neutralizing cold water and hot water. Thus, the device has the disadvantages of overlarge volume, occupied space, unchanged installation and unattractive appearance.

When people wash their face and rinse their mouth, the hot water in the water heater and the cold water in the water pipe are mixed by the water mixing valve of the water equipment and then the water with the temperature being neutralized is discharged. Therefore, the hot water used in actual washing is not large, the hot water can be fully utilized as long as the cold water and the hot water are prevented from being mixed and cooled in the water container, and the capacity of the water heater is actually very small, so that the use can be met.

Disclosure of Invention

In order to overcome the problems in the prior art, the invention provides a water storage type water heater which fully utilizes hot water, has a small and exquisite structure, is convenient to install, and can achieve the complete utilization of the hot water, thereby saving energy consumption.

The scheme for solving the problems in the prior art is as follows: a water storage type water heater capable of fully utilizing hot water is composed of an air compressing system and a water storage system, and comprises an air compressor, a check valve, an air storage tank, a water container, an electric valve, a pressure reducer, a safety valve, a balance valve and the like. When the air compressor works, external air is sucked by the air compressor and compressed into high-pressure air which is sent into the air storage tank for storage. The water inlet of the water container is connected with a tap water pipeline, and the water outlet is connected with a water using equipment pipeline. The water container is internally provided with a heating pipe which is responsible for boiling water.

The invention is intended to be divided into three modes of operation: "replenishment mode", "high efficiency mode", and "normal mode".

When the high-efficiency mode is used, the water using equipment is started, the electric valve between the air storage tank and the water container is automatically opened, and because the pressure of the gas stored in the air storage tank is far greater than the pressure in the water container, the high-pressure air stored in the air storage tank is filled into the water container through the electric valve, and the hot water in the water container is extruded out through the water outlet. When the hot water is used up, the mode is automatically switched to the 'replenishment mode', or the mode is manually switched to the 'replenishment mode' after the washing is finished. At the moment, an electric valve between the air storage tank and the water container is automatically closed, the balance valve and the water inlet valve are automatically opened, and most of air in the water container and the air are discharged through the balance valve while cold water is supplemented. And simultaneously, the air compressor starts to work, high-pressure air is supplemented to the air storage tank for the next use, and the air compressor automatically stops when the air storage tank reaches a set pressure value. Therefore, the aim of fully utilizing the hot water can be achieved by the working mode of only discharging the hot water and not mixing the hot water with the cold water during washing.

The invention has the beneficial effects that: the hot water utilization rate is extremely high, thereby saving energy consumption. Meanwhile, the volume and the overall dimension of the water heater can be greatly reduced, the occupied space is reduced, and the arrangement and the installation are convenient.

The specific implementation mode is as follows:

the following description of the embodiments of the present invention will be made with reference to the accompanying drawings: as shown in fig. 1, the water storage type water heater fully utilizing hot water comprises two parts, namely an air compressing system and a water storage system.

The air compressor 1 and the air storage tank 4 in the air compression system are connected through a pipeline, and a check valve 2 is arranged on the pipeline between the air compressor 1 and the air storage tank 4, so that air is only allowed to flow from the air compressor 1 to the air storage tank 4. Be equipped with pressure sensor 3 and relief valve 6 on the gas holder 4, pass through the tube coupling between gas holder 4 and the water container 10, set gradually electric valve 5 and pressure reducer 8 on the pipeline No. one.

The top of a water container 10 in the water storage system is provided with a balance valve 7. The upper part of one end of the water container 10 is provided with a high liquid level sensor 9, and the lower part is provided with a low liquid level sensor 13. The other end of the water container 10 is provided with a heating device 12 which extends into the water container. The bottom of the water container 10 is provided with a magnesium rod 11, a water outlet 14 and a water inlet 18 from left to right in sequence. The water outlet 14 is a long pipe with two through ends, the upper opening is inserted into the water container 10 for a certain length and is close to the top but lower than the high liquid level sensor 9, and the lower opening is provided with a second electric valve 15. The pipeline led out from the lower port of the second electric valve 15 is divided into a vertical pipeline and a horizontal pipeline, and the vertical pipeline leads to water utilization equipment. The water inlet 18 is a short pipe with two through ends, which does not need to be inserted into the water container 10 too much, the upper opening exceeds the lower bottom of the water container 10 but is lower than the low liquid level sensor 13, and the lower opening is led out of a pipeline, which is also divided into two paths of vertical and horizontal. The horizontal pipeline is connected with the horizontal pipeline at the lower port of the second electric valve 15, and a third electric valve 16 is arranged between the horizontal pipeline and the second electric valve. A fourth electric valve 17 is arranged on a vertical pipeline at the lower opening of the water inlet 18, and the lower opening of the fourth electric valve 17 is connected to a tap water pipeline.

The working process is as follows: the invention is divided into a supply mode, an efficient mode and a conventional mode when in use.

The starting-up default starts the 'supply mode' air compressor 1 to start working, air is compressed and then is filled into the air storage tank 4 through the check valve 2, and when the pressure sensor 3 detects that the pressure in the air storage tank 4 reaches a set value, a signal is sent immediately to stop the air compressor 1. At this time, the check valve 2 prevents the high-pressure gas in the air tank 4 from flowing back to the air compressor 1 to leak after the air compressor 1 is stopped. When the pressure sensor 3 fails or is detected inaccurately, and the pressure in the gas storage tank 4 exceeds a safety range, the safety valve 6 automatically opens to discharge gas and release pressure, so that the pressure is ensured to be in the safety range.

In the replenishment mode, the balance valve 7 and the fourth electrically operated valve 17 are in an open state, and the rest electrically operated valves are in a closed state. Tap water is injected into the water container 10 through the four-position electric valve 17 and the water inlet 18, and air in the water container 10 is discharged through the balance valve 7 along with the rise of the water level. When the water level rises to the position of the high liquid level sensor 9, the high liquid level sensor 9 sends a signal to close the balance valve 7, the pressure in the water container 10 is balanced with the pressure of the tap water pipeline to stop water injection, the heating device 12 is started to start heating after the water injection is completed, and the heating is stopped after the water is heated to a preset temperature to be in a standby state.

When the high-efficiency mode is started, the first electric valve 5 and the third electric valve 16 are opened, and the other electric valves are closed. High-pressure air stored in the air storage tank 4 flows through the first electric valve 5, and is reduced to set tap water pipeline pressure through the pressure reducer 8 and then is filled into the water container 10. With the charging of the air, the hot water in the water container 10 is extruded out through the water inlet 18 and the third electric valve 16, and is led to a water utilization device to be mixed with cold water for temperature adjustment. When the hot water in the water container 10 is about to be used up and the water level drops to the position of the low liquid level sensor 13, the low liquid level sensor 13 immediately sends a signal to start the 'supply mode' to replenish water and high-pressure air, and at the moment, the water is not drained any more.

When the 'normal mode' is started, the water heater can be used as a normal water storage type water heater, namely, hot water is used while cold water is supplemented. In this mode, the second electric valve 15 and the fourth electric valve 17 are opened, and the remaining electric valves are closed. The air compressor 1, the pressure sensor 3, the balance valve 7, the high liquid level sensor 9 and the low liquid level sensor 13 stop working. When washing, hot water in the water container 10 is discharged from the upper opening of the water outlet 14 to the lower opening and then flows into water utilization equipment through the second electric valve 15 in an open state, and meanwhile, running water cold water is injected into the water container 10 through the fourth electric valve 17 and the water inlet 18 in the open state for supplement, and the process is repeated.
