Instant drinking water heating device

Abstract

The invention relates to an instant drinking water heating device which comprises a water outlet spout, an instant pipeline heater and a water inlet pipe. The instant drinking water heating device is characterized by further comprising a water level tank which is provided with a water inlet and a water outlet, the water inlet is connected with the water inlet pipe, the water outlet is communicated with an inlet of the instant pipeline heater, and a floating ball component which adjusts water inlet quantity of the water inlet through water level height is arranged in the water level tank. The instant drinking water heating device has the advantages that the water inlet quantity of the water inlet of the water level tank is controlled by the aid of the floating ball component and by utilizing water in the water level tank to serve as buoyancy, and accordingly, automatic adjustment of water level of the water level tank is achieved.

Description

technical field [0001] The invention relates to a drinking water heating device, in particular to an instant drinking water heating device. Background technique [0002] Existing instant drinking water heating devices, such as: instant electric kettle, instant water dispenser, instant tea tray, instant tea making utensils, instant tea making machine, etc., the heater used It is an instant electric pipeline heater, such as a quartz glass tube heater, or a pipeline heater with an electric heating wire on the outer wall of the tube, or a pipeline heater with a heating body in the tube cavity; its internal structure generally includes a water outlet, Instantaneous pipeline heater, balance water tank, water inlet pipe, water pump and water storage tank. The water inlet, water outlet and return port are opened on the balance water tank. Connect the water storage tank, the water outlet of the balance water tank is connected to the inlet of the instantaneous pipeline heater, the ou...

Problems solved by technology

[0003] However, the instant drinking water heating device with the above structure still has the following disadvantages: (1) In view of the small volume of the balance water tank, a water inlet, a water outlet and a return port (three ports) should be set on the balance water tank , the process requirements are relatively high; moreover, setting so many openings on such a small balance water tank will cause the overall strength of the balance water tank to be low, easily deformed, or even damaged; (2) In view of the fixed size of the return port, When the water level in the balance tank is unstable, such as: the water level is too high or too low, the water level cannot be automatically adjusted
