Description

Water heater with uniform heating temperature

Technical Field

The utility model relates to the technical field of water heaters, in particular to a water heater with uniform heating temperature.

Background

The existing water heaters on the market are not uniformly heated, so that the water heaters are suddenly cooled and suddenly heated when people take a bath, and great defects exist.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

In order to solve the problems in the prior art, the utility model provides the water heater with uniform heating temperature, which can ensure uniform outlet water temperature and meet the needs of people.

(II) technical scheme

In order to achieve the purpose, the utility model adopts the main technical scheme that: including pure water case, inlet tube, install suction pump, heater and the controller on the inlet tube, first circulating pipe is installed to heater delivery port one end, the agitator is installed to the first circulating pipe other end, the agitator goes out the water end and passes through tee bend and pipe and pure water case intercommunication, install the circulating pump on the pipe, the drain pipe is installed to another delivery port of tee bend, install a NTC thermistor on the agitator.

Preferably, a second NTC thermistor is mounted on the drain pipe.

Preferably, a check valve is installed on the water inlet pipe.

Preferably, the stirrer shell is made of a heat-insulating material.

(III) advantageous effects

The utility model provides a water heater with uniform heating temperature. The method has the following beneficial effects:

(1) the water demand is received to the controller, at first start the suction pump and supply the heater heating to the inside water of pure water case, in hot water after the heating entered into the agitator, the agitator work stirred hot water, the temperature in the stirring afterheater has guaranteed the even of temperature, the hydrothermal temperature of the interior storage of agitator can be monitored constantly to first NTC thermistor on the agitator, when the temperature loss, the starting circulating pump, the water in the agitator is through the heater reheating storage. (the heater and the stirrer are designed separately, so that later-stage maintenance is facilitated).

(2) The second NTC thermistor on the drain pipe can further monitor the drainage temperature, when the drainage temperature reaches the standard, the controller just can control the drain pipe drainage (install the solenoid valve on the drain pipe), when first NTC thermistor takes place to damage, can avoid discharging each other the water overheated or too cold, causes the accident.

Drawings

FIG. 1 is a block diagram of the present invention.

In the figure: 1. a pure water tank; 2. a water inlet pipe; 3. a water pump; 4. a heater; 5. a controller; 6. a first circulation pipe; 7. a stirrer; 8. a circulation pump; 9. a drain pipe; 10. a first NTC thermistor; 11. a second NTC thermistor; 12. a check valve.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the water heater with uniform heating temperature of the embodiment includes a pure water tank 1, a water inlet pipe 2, a water pump 3 installed on the water inlet pipe 2, a heater 4 and a controller 5, wherein a first circulation pipe 6 is installed at one end of a water outlet of the heater 4, a stirrer 7 is installed at the other end of the first circulation pipe 6, a water outlet end of the stirrer 7 is communicated with the pure water tank 1 through a tee joint and a conduit, a circulation pump 8 is installed on the conduit, a water outlet pipe 9 is installed at the other water outlet of the tee joint, and a first NTC thermistor 10 is installed on the stirrer 7. The controller 5 receives the water demand, firstly, the water suction pump 3 is started to supplement water in the pure water tank 1 to the heater 4 for heating, the heated hot water enters the stirrer 7, the stirrer 7 works to stir the hot water, the temperature of the water in the heater 4 is guaranteed to be uniform after stirring, the first NTC thermistor 10 on the stirrer 7 can monitor the temperature of the hot water stored in the stirrer 7 at any time, when the temperature is lost, the circulating pump 8 is started, and the water in the stirrer 7 is reheated and stored by the heater 4.

Further, a second NTC thermistor 11 is mounted on the drain pipe 9. The second NTC thermistor 11 on the drain pipe 9 can further monitor the drain temperature, when the drain temperature reaches the standard, the controller 5 will control the drain pipe 9 to drain (the electromagnetic valve installed on the drain pipe 9), and when the first NTC thermistor 10 is damaged, the overheating or over-cooling of the water discharged from each other can be avoided, which causes an accident.

Further, a check valve 12 is installed on the water inlet pipe 2.

Further, the shell of the stirrer 7 is made of heat-insulating materials.

The working principle is as follows: the controller 5 receives the water demand, firstly, the water suction pump 3 is started to supplement water in the pure water tank 1 to the heater 4 for heating, the heated hot water enters the stirrer 7, the stirrer 7 works to stir the hot water, the temperature of the water in the heater 4 is guaranteed to be uniform after stirring, the first NTC thermistor 10 on the stirrer 7 can monitor the temperature of the hot water stored in the stirrer 7 at any time, when the temperature is lost, the circulating pump 8 is started, and the water in the stirrer 7 is reheated and stored by the heater 4. The second NTC thermistor 11 on the drain pipe 9 can further monitor the drain temperature, when the drain temperature reaches the standard, the controller 5 will control the drain pipe 9 to drain (the electromagnetic valve installed on the drain pipe 9), and when the first NTC thermistor 10 is damaged, the overheating or over-cooling of the water discharged from each other can be avoided, which causes an accident. Wherein, the heater 4 and the agitator 7 are separately designed, so that the later-stage maintenance is convenient.
