Description

Instant heat energy saving water dispenser

Technical field

The utility model relates to a water dispenser, in particular to an instant heat energy-saving water dispenser. An instant heat energy-saving water dispenser without repeated heating specifically relates to a bimetal sheet flow regulating device of the water dispenser and a temperature control mode of the water dispenser.

Background technique

The traditional water dispenser hot water system consists of an insulated tank and a heating element. There is a waiting time for heating when it is first started, and the water in the insulated tank can be heated to drinking temperature before drinking. During the standby process, due to the heat loss in the heat preservation tank, it needs to be heated repeatedly to achieve the heat preservation effect. This water boiled repeatedly and constantly kept warm is commonly known as "thousand boiling water", and drinking it for a long time will have adverse effects on people's health.

Chinese Utility Model Patent No.: 200820049328.2, which discloses an instant water dispenser. The core idea is to use "mosquito coil" type electric heating to heat drinking water, and remove the heat preservation tank to achieve the purpose of instant heating of drinking water. The water dispenser cannot adapt to the voltage change of the grid, which will cause the change of the heating power, resulting in that the temperature of the water outlet cannot be guaranteed. At the same time, it may change with time, and scale will form on the heater, resulting in a decrease in the heat transfer coefficient and attenuation of the heating performance.

Other instant water dispensers that have appeared in recent years have problems such as unstable water outlet temperature and performance degradation over time. There are also some instant heating that need to adopt complex electronic control components, which have complex structures, reliability cannot be guaranteed, and the production cost is relatively high.

Contents of the invention

In order to overcome the deficiencies in the applicable voltage range and performance of existing instant hot water dispensers, and simplify the mechanism to the greatest extent to reduce costs, the utility model provides an instant heat energy-saving water dispenser, which can adapt to the voltage in the power grid It can stably provide high-temperature drinking water that meets the temperature requirements, and the performance is stable, and the performance will not attenuate with the increase of the service life.

The technical scheme adopted by the utility model to solve the technical problem is: an instant heat-saving energy-saving water dispenser, including a housing, a cold water tank installed in the upper part of the housing and a smart seat located in the cold water tank. The heating tank connected to the water tank, the combination switch, the cold drinking water outlet connected to the cold water tank, the hot drinking water outlet connected to the heating tank and the hot drinking water switch; there is an electric heating core in the heating tank, which is controlled by bimetal and temperature The water outlet temperature control valve composed of valve spool, one end of the bimetal sheet is fixed on the heating tank body, and the other end is connected to the temperature control valve spool; the temperature control valve spool and the bimetal sheet jointly control the water outlet speed to ensure the water outlet temperature; the electric heating core is connected to the combined switch through wires; the steam discharge pipe on the top of the heating tank leads to the inside of the cold water tank.

The working principle is: when the hot drinking water switch on the panel of the water dispenser is turned on, the power of the heating core is turned on, and when the drinking water in the heating tank is heated to boiling water, the bimetal sheet is heated to bend inward, and the temperature is pulled apart. Control the spool of the valve, and the high-temperature drinking water flows out from the hot drinking water outlet. As long as the hot drinking water switch is not turned on, the power supply of the heating core will not be connected again, and the drinking water in the heating tank will not be heated repeatedly. During the heating process, the exhaust gas in the heating tank is discharged through the steam discharge pipe. At the same time, the steam discharge pipe has the function of preventing the pressure in the heating tank from being too high, and preventing the high-temperature drinking water from flowing out into a jet during use.

When the grid voltage decreases, the power of the heating core decreases accordingly, and the temperature of the water in the heating tank decreases accordingly, so that the bimetal sheet will stretch due to the decrease in temperature, thereby pushing the temperature control valve to reduce the water outlet gap, thereby Reduce the flow of water outlet to achieve the balance of water outflow and heating power, and strictly guarantee the temperature standard of water outlet. Since the bimetal sheet is a moving part during use and will not stick to scale, the temperature control valve can ensure reliable control performance and ensure that the performance of the water dispenser will not decay over time.

The beneficial effects of the utility model are: simple structure, low production cost, stable and reliable performance. It can provide qualified high-temperature drinking water, and the performance of the water dispenser is not affected by the grid voltage. It is ready to drink when it is hot, and has a good energy-saving effect.

Detailed ways

Referring to FIG. 1 , the instant energy-saving water dispenser includes a housing 14 , a cold water tank 10 , a smart seat 1 , a heating tank 12 and a combination switch 6 . The heating tank 12 has an electric heating core 13, a bimetal strip 4 and a temperature control valve spool 5, and the electric heating core 13 is connected to the combination switch 6 through a wire 9; The water tank 10 is connected, and the top of the heating tank 12 has a steam discharge pipe 2 leading to the inside of the cold water tank 10, which is used to discharge the waste steam in the heating tank 12 and prevent the pressure in the heating tank 12 from being too high; Drinking water switch 7 and hot drinking water outlet 8; the combined switch 6 is arranged between the heating tank 12 and the hot drinking water outlet 8. One end of the bimetal 4 is fixed on the heating tank 12 tank body with a temperature adjustment screw 3 .

As shown in Figures 2 and 3, the combination switch 6 is composed of a hot drinking water switch 7, a switching valve core 15 connected to the hot drinking water switch 7, and a power switch 16 controlled by the hot drinking water switch 7. In the present embodiment, the power switch 16 is positioned under the hot drinking water switch 7, and the power switch 16 is turned on when the hot drinking water switch 7 moves. The bimetallic sheet 4 is composed of a copper sheet 41 and an aluminum sheet 42 with different thermal expansion coefficients bonded together.

As shown in Figure 2, under the standby state, the switch spool 15 and the temperature control valve spool 5 are closed, the power switch 16 is disconnected, the water dispenser is in the standby state, no water is produced, and no power is consumed.

As shown in Figure 3, under the use state, the hot drinking water switch 7 moves to the left under the external force of people, directly pushes the switch spool 15 to open, and at the same time turns on the power switch 16. At this time, the electric heating core 13 is energized and heated. The cold drinking water in the tank 12 is heated, and the copper sheet 41 and the aluminum sheet 42 in the bimetal sheet 4 are subjected to the effect of drinking water and expand, and the thermal expansion coefficient of copper is greater than that of aluminum, so the bimetal sheet will move toward the aluminum sheet. The side bends and shrinks, and the temperature control valve 5 is pulled to move to the left. When the temperature reaches 95 degrees Celsius, the temperature control valve 5 is completely opened, and hot drinking water flows out from the hot drinking water outlet 8 along the direction indicated by the arrow. After finishing using, hot drinking water switch 7 is bounced, gets back to the standby state of Fig. 2.
