Description

A double constant temperature foot bath bucket based on phase change materials

Technical field

The invention relates to a constant-temperature foot bath bucket, and in particular to a double constant-temperature foot bath bucket that can achieve two different constant temperatures by injecting two phase change materials at the same time.

Background technique

Foot bath buckets are commonly used items in people's daily lives. Soaking feet in a foot bath bucket is beneficial to dredging the meridians of the soles of the feet and promoting blood circulation. It is a good way to maintain health. The constant temperature of the hot water in the foot bath bucket has an important impact on the comfort and efficacy of the foot bath. At present, the main method of maintaining a constant temperature for foot massage buckets is electric heating. In the process of maintaining a constant temperature, frequent heating is required, which consumes electricity. There is also the risk of electric leakage. At the same time, it is limited by the position of the power supply and cannot be moved at will, resulting in a lack of flexibility. In addition, current foot bath buckets usually only have one hot water tank, which cannot meet people's needs for two hot water temperatures at the same time. Phase change materials can store or release heat energy through phase change at the phase change temperature. They have the characteristics of absorbing and releasing heat at a constant temperature. They can be heated with hot water without electric heating, and can be placed in a foot bath bucket. Two phase change materials are used to obtain two different constant temperatures.

Contents of the invention

In order to change the current shortcomings of electric heating for constant temperature of foot massage buckets, which has the hidden danger of leakage and can only provide a single hot water tank, the present invention provides a dual constant temperature foot massage bucket without electric heating, using phase change materials for constant temperature, and through the structure The design is divided into left and right parts and each is filled with two different phase change materials to meet people's demand for two constant-temperature hot water at the same time.

In order to achieve the above objects, the technical solution of the present invention is as follows: a double constant temperature foot bath bucket based on phase change materials, which is composed of a thermal insulation shell, a phase change material, a phase change material partition, a thermally conductive inner tank and a middle thermal insulation partition. The middle layer between the shell and the thermal conductive liner is divided into two disconnected left and right halves by a phase change material partition, which are filled with phase change materials with different phase change temperatures; the middle insulation partition has a heat insulation function and is placed In the foot bath bucket, the two sides and bottom surface of the middle thermal insulation partition are in close contact with the two side walls and bottom surface of the thermal conductive liner respectively, dividing the internal space of the foot massage bucket into two non-connected left and right parts; the middle thermal insulation partition The plate can move left and right along the wall of the thermal conductive liner and stay at any position to adjust the volume of the left and right parts of the foot bath bucket; the phase change material can be paraffin with phase change temperatures of 35-40°C and 45-50°C respectively; Hot water with a temperature higher than the phase change temperature is added to the foot massage bucket. The hot water releases heat and cools down. The phase change material absorbs heat to heat up and melt. After a few minutes, the temperature of the hot water in the left and right parts of the foot massage bucket drops to its respective phase. After that, the phase change material solidifies and releases heat to maintain a constant temperature of the hot water in the left and right parts of the foot bath barrel for a long period of time.

Compared with the known technology, the present invention has advantages and positive effects: the double constant temperature foot bath bucket can quickly keep the temperature of hot water at a suitable temperature required by the human body and maintain it for a long time without the need for electric heating and the safety it brings. Hidden danger; it can provide two hot water tanks with different constant temperatures at the same time to meet people's needs for hot water with two different constant temperatures at the same time; the foot bath bucket can be moved at will, and the two hot water tanks are adjustable in size and flexible to use.
