Description

temperature regulator

The present invention relates to a temperature regulator, and in particular, to a temperature regulator that can quickly cool hot food and drink materials to a temperature that is hot but not scalding, and releases thermal energy when the hot food and beverage materials are cooled, so that the hot food and drink materials can maintain a suitable drinking temperature for a period of time. .

In a cold environment, drinking a hot drink can keep people's bodies warm. However, hot drinks are not always better. According to the definition of hot drinks by the World Health Organization, the temperature of hot drinks is between 50°C and 65°C. Hot drinks with a temperature in this range can make people enlarge their tongue senses and have a better flavor. As for hot drinks with a temperature above 65°C, , it will harm people's mouth and destroy the flavor of hot drinks.

Generally speaking, when hot drinks such as hot tea and coffee are brewed with hot boiling water in the early stages of brewing, they are at a scalding temperature. Usually, the hot drinks in the container are placed for a period of time to cool down before drinking. This method has problems such as waiting too long for the hot drink to cool down to a suitable drinking temperature, and making it difficult to control the temperature of the hot drink after cooling down. For this reason, someone has designed a cup with a rapid cooling function. This cup can put hot boiling water or brewed hot drinks into it, and seal it with a lid. After shaking the cup for about 1 minute, the cup will The heat-absorbing material inside absorbs heat and cools the hot boiling water or brewed hot drinks, so that the hot boiled water or brewed hot drinks filled in the cup is cooled from the original scalding temperature to the suitable drinking temperature, so that the user can drink it conveniently.

Although the above-mentioned known cup has the function of quickly cooling the hot drink to a suitable drinking temperature, the overall structure of the cup is relatively complex, the price is high, and the shape is too large. The hot drink must be poured into the cup and covered. Shake it after closing. If the lid is not sealed properly, it may leak out when shaken, which may cause inconvenience.

The main purpose of the present invention is to provide a temperature regulator that solves the inconveniences of existing cups with a rapid cooling function, such as complex overall structure, high price, large size, and the need to pour hot drinks into the cup, cover it, and then shake it. etc. questions.

In order to achieve the aforementioned objectives, the temperature regulator proposed by the present invention is placed in a heat source in a container, and includes: a thermally conductive shell with a sealed space inside; and a solid-liquid phase change material. , which is filled in the closed space of the thermally conductive shell. The solid-liquid phase change material can absorb the thermal energy of the heat source through the external thermally conductive shell, store the thermal energy through the endothermic phase change, and store the thermal energy in the heat source. During cooling, the solid-liquid phase change material releases heat energy to maintain the temperature of the heat source within a preset time.

Through the invention of the aforementioned temperature controller, it has at least the following advantages:

1. Good portability: The temperature controller of the present invention adopts a simplified structure, and it can be easily designed into a small object with a small size according to actual product use requirements, so that users can carry it with them.

2.

At the same time, it stores the heat energy through the phase change of endothermy, and can release heat energy through the solid-liquid phase change material when the hot drink is cooled. Keep hot drinks at a suitable drinking temperature for a period of time. It allows users to drink hot drinks at a suitable drinking temperature within a preset time, avoiding the problems of burns and coldness, and easily having the perfect hot drink flavor.

3. The number of placed temperature regulators can be adjusted according to the amount of heat source: As mentioned above, the temperature regulator of the present invention can be designed as a small object with a small size. In use, it can be installed according to the amount of hot boiling water, The size of the container for hot drinks such as hot tea and coffee and the temperature control of the hot drinks are left to the user to choose the number of temperature regulators they put in.

Time changes, among which, as can be seen from the curve L1 shown in Figure 9, the hot drink is subject to the insulation effect of the thermos bottle, and it takes a long time to cool down to the temperature in the appropriate temperature zone. In a short period of time, the hot drink is at the scalding temperature, and the user cannot drink it. It can be seen from the curve L2 shown in the figure that when the hot drink is naturally cooled at room temperature, it is difficult to cool down to the temperature of the appropriate temperature zone in a short period of time, and the user cannot drink it. It can be seen from the curve L3 shown in Figure 9 that when the temperature regulator of the present invention is placed in the hot drink, the hot drink can be quickly cooled to about 60°C, and the hot drink can be kept at a temperature of 60°C, allowing the user to pre-set the temperature. within the set time Drinking hot drinks that are maintained at the right drinking temperature avoids the problems of scalding and cooling, and you can easily have the perfect hot drink flavor.

Furthermore, the casing of the temperature regulator of the present invention can be made of antibacterial heat-conducting material.
