The intelligent instant drinking water heating device comprises a casing, a balance water tank disposed on the casing, a hot pipe heater and a water pump, the balance water tank is provided with a water inlet and a water outlet, and the water inlet is connected with a water pump and a water outlet. The hot pipe heater is connected, wherein the balance water tank is provided with a water shortage water level probe and a balance water level probe, and the water shortage water level probe and the balance water level probe are both electrical conductors, and the water shortage water level probe and the instant water pipeline The heater is electrically connected, and the balance water level probe is electrically connected with the water pump; this is a hot drinking water heating device, which utilizes the water level rise or fall principle by setting a water shortage water level probe and a balance water level probe in the balance water tank. Automatically balance the water shortage level and balance water level in the water tank by turning the water on or off (two) water level probes and turning on or off the balance water level probe (with one of the water shortage level probes) Control protection, that is, the hot pipe heater when the water level in the water tank is too low (water shortage) When the water level in the balance water tank reaches the equilibrium water level probe, the balance water level probe is connected with one of the water shortage water level probes to automatically control the water pump to open or stop, and maintain a stable equilibrium water level. The structure is simple and reasonable. The process requirements for installation are low.

The present invention can further adopt the following technical solutions:

As a more preferred solution, the water shortage water level probe and/or the balance water level probe are installed on the upper part of the balance water tank, that is, the water shortage water level probe and/or the balance water level probe can be inserted into the balance water tank from the upper or top of the balance water tank.

The outlet of the pipeline heater, and the height of the outlet is generally close to the equilibrium water level in the balance tank (or balance:), so that the heated water in the hot-pipe heater is sufficient in the balance tank. The high water level, when boiling, is easy to push out the water, so the higher the equilibrium water level of the balance tank (ie the hot water in the hot pipe heater is easily pushed out) the lower the outlet water temperature, on the contrary, the balance water tank The lower the equilibrium water level (ie, the hot water in the hot pipe heater has a certain height difference from the water outlet, the more difficult it is to be pushed out, the greater the boiling force must be. Release can hot) water temperature is higher, and therefore, according to the different requirements of users water temperature, water level probe by adjusting the height balance in the balance tank to enable adjustment of the water temperature.

As a more specific solution, the water shortage water level probe includes a first water shortage water level probe and a second water shortage water level probe, and a distance exists between the two water shortage water level probes; that is, if the level reaches a certain height The two water-deficient water level probes are connected. On the contrary, if the level is too low, two or one of the water-deficient water level probes are suspended in the balance water tank, that is, the power is cut off, where the hot-tube heater is powered off. Prevent the water level from being too low and cause dry burning.

The first water shortage water level probe and the second water shortage water level probe are respectively disposed at an upper portion or a top portion of the balance water tank and extend toward the bottom of the balance water tank, that is, the water shortage water level probe is simply inserted from the top or the upper portion of the balance water tank.
