Tea making machine and self-adjusting control method for power of water pump thereof

Abstract

The invention discloses a tea making machine which comprises a water inlet pipeline, an instant heating type pipeline heater and a water outlet nozzle, wherein a water pump is arranged on the water inlet pipeline; an inlet of the instant heating type pipeline heater is communicated with the water inlet pipeline; an outlet of the instant heating type pipeline heater is connected with the water outlet nozzle; the tea making machine further comprises an entering water temperature probe and a water pump power control device; the entering water temperature probe is arranged on the water inlet pipeline; the water pump, the entering water temperature probe and the water pump power control device are electrically connected; and the water pump power control device is used for automatically adjusting the power of the water pump according to an entering water temperature value, so as to realize the corresponding water flow speed and ensure the discharged water temperature meeting the set demand. The invention also discloses a self-adjusting control method for the power of the water pump of the tea making machine. A plurality of water pump power value gears are preset on the water pump power control device, a water pump power error value meter is also arranged, and the power of the water pump is adjusted and finely adjusted through corresponding to an entering water temperature value and a discharged water temperature value,, so that a user can use the hot water at a preset discharged water temperature which is suitable for tea making. The operation is almost full-automatically performed. The operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of tea making utensils, in particular to a tea making utensil and a method for self-adjusting and controlling the power of a water pump. Background technique [0002] Existing tea making utensils mainly refer to tea trays and coffee tables with boiling water function, which use boiled water for users to make tea immediately; while traditional tea making utensils, their structures include water inlet pipelines, instant hot water There is a water pump on the water inlet pipe, and the inlet of the instant pipe heater is connected to the water inlet pipe, and its outlet is connected to the water outlet. The water is sent into the instant pipe heater for heating. Since the power of the water pump is constant, the flow rate of the water flowing through the instant pipe heater is constant, that is to say, the time for the water flowing through to be heated is constant; Constant, the outlet water temperature is als...

AI Technical Summary

Problems solved by technology

However, the tea-making appliance with the above structure still has the following disadvantages: (1) Since the instantaneous pipe heater is set at a constant power when it leaves the factory, however, in different regions, especially in different seasons, the ambient temperature It will affect the inlet water temperature. If the inlet water temperature is different due to regions or seasons, when the power of the instantaneous pipe heater remains unchanged (that is, the flow rate through the heater tube remains unchanged), the outlet water temperature will be due to the difference in the inlet water temperature. , resulting in differences in the outlet water temperature, making it impossible to achieve the set outlet water temperature, which affects the taste of tea
