Background

Milk beverage heating and stirring machines are widely used in the household and commercial fields, generally refer to appliances for heating, stirring and foaming milk, and are commonly used as milk foaming machines and milk tea machines.

The milk foam machine mainly has three functions: the method comprises the steps of preparing normal-temperature milk foam, preparing hot milk foam and heating milk, wherein the temperature range of the milk heating is generally about 60-70 ℃, after the milk is processed, adding the milk and the milk foam with different proportions into coffee to prepare various fancy coffee such as cappuccino (cappuccino), latte (latte) and the like, and sometimes, adding the chocolate during the milk heating to prepare milk chocolate beverage so as to meet various taste requirements of users.

In the heating process of the milk beverage heating blender, the temperature of the milk in the cup body of the milk beverage heating blender needs to be measured through the temperature control device, so that the temperature of the milk is controlled at a preset value (generally about 60-70 ℃) of a better foaming temperature, and a sufficient milk foaming amount and a good taste are kept. In the prior art, a through hole is usually arranged on the heating plate, and the temperature control device is arranged in the through hole in a penetrating way to be in contact with the bottom of the cup body for temperature measurement. For example, patent publication No. CN101485541B and utility model patent publication No. CN201445368U disclose a cup for heating, stirring and foaming liquid food, which is separable from a heating plate in a heating base. As shown in fig. 2 of the patent document, the heating plate has three through holes passing through the thickness direction thereof, namely a middle hole at the center of the heating plate for mounting a retainer ring, a through hole for mounting a temperature controller, and a through hole for activating a push rod of a micro switch; the temperature is measured by contacting the bottom of the cup with a temperature controller and the micro switch push rod is started.

The temperature measuring mode has the following defects that the temperature controller assembly is arranged in the heating plate in a penetrating way, is greatly influenced by the temperature of the heating plate, has low temperature measuring precision, and is provided with the through hole, so that the heating efficiency is relatively reduced; especially when the same milk bubble machine heats milk or beats hot milk bubble many times in succession, the dish that generates heat is in higher temperature state all the time, temperature controller temperature measurement accuracy is worse, it is lower that the temperature of the hot milk of following number of times or hot milk bubble is more, the shorter the stirring time, the stirring is less enough, milk foaming is less enough, milk bubble effect is poor, the reason is that hot milk or hot milk bubble actual temperature is on the low side, do not reach the milk foaming's of preferred preset temperature value, influence the taste, need to wait to generate heat the dish temperature and reduce to near normal atmospheric temperature just resume normal, influence user experience, it is more to generate heat the dish upper opening simultaneously, there is the potential safety hazard.

The prior art proposes a technical scheme of measuring the temperature of milk by using an infrared sensing device, for example, a utility model with an authorization publication number of CN203483288U discloses a milk frother, which comprises a base and a milk cup, wherein the milk cup is arranged on the base; a rotatable active magnetic head is arranged in the base; a stirring device is arranged in the milk cup body and comprises a stirring head containing a magnet; the driving magnetic head is vertically aligned with the stirring head; the base is also provided with an infrared induction device. The base is provided with a concave position for placing the milk stirring cup. The infrared sensing device can be arranged on the side wall of the concave position and also can be arranged on the bottom surface of the concave position; the infrared sensing device is used for sensing the existence of the cup body so as to control the operation or power-off of the machine and also used for sensing and controlling the milk temperature.

An infrared induction device is used for inducing the existence of the cup body on the heating plate, and the function similar to that of a microswitch is realized, so that the operation or the power failure of the milk foam maker is controlled; the infrared sensing device is also used for sensing and controlling the temperature of the milk; the temperature measuring mode has relatively high cost and is easily influenced by the interference of the waste heat of the heating plate, and particularly, when the same milk frother continuously heats milk for multiple times, the temperature measuring precision and sensitivity of the infrared sensing device are reduced, and the temperature measuring effect is not ideal.
