Abstract
Description
Technical Field
[0001] This utility model relates to a thermos kettle inner liner. Background Technology
[0002] In the home, a kettle with a constant temperature can meet the family's need for hot water at any time. Water boiled in the morning can still maintain a certain temperature by noon or even evening, without the need for frequent reheating.
[0003] Office workers need to stay hydrated frequently during work hours. This type of electric kettle can continuously provide hot water, reducing waiting time and improving work efficiency. Common designs use double-walled stainless steel or glass materials to create a vacuum layer.
[0004] In addition to ensuring the physical function of heat preservation, the design of electric kettles is increasingly focusing on fashion and user-friendliness. For example, they adopt ergonomic handle designs for easy gripping; and their simple and elegant appearance can match various home environments.
[0005] However, the inner liner of the kettle is currently unable to conduct heat efficiently while ensuring insulation. Utility Model Content
[0006] In order to overcome the shortcomings of current thermostatic kettles in terms of efficient heat conduction, this utility model provides a thermostatic kettle inner liner and a kettle using the inner liner.
[0007] The technical solution of this utility model to solve its technical problem is: a constant temperature kettle inner liner, wherein the upper part of the constant temperature kettle inner liner is a water inlet and the lower part is a heating element. The constant temperature kettle inner liner consists of an inner stainless steel layer, an inner aluminum layer, and an outer aluminum layer from the inside out. A heat-conducting liquid channel is provided between the inner aluminum layer and the outer aluminum layer, and the heat-conducting liquid channel is filled with heat-conducting liquid. The heat-conducting liquid is a phase change heat-conducting liquid.
[0008] To increase structural strength, an outer stainless steel layer is also provided outside the outer aluminum layer.
[0009] To facilitate the setting of the heat transfer fluid channels, the heat transfer fluid channels are formed by raised textures protruding from the outer aluminum layer.
[0010] In a preferred embodiment, the raised texture is a honeycomb pattern.
[0011] To facilitate pouring water, the inner liner of the thermostatic kettle is equipped with a spout at the water inlet.
[0012] This utility model also relates to a kettle, including a kettle shell with a lid and a handle. An inner liner is located inside the kettle shell, and an electric heating device is located below the inner liner. The inner liner is a constant temperature kettle liner, with a water inlet at the top and a heating element at the bottom. The constant temperature kettle liner consists of an inner stainless steel layer, an inner aluminum layer, an outer aluminum layer, and an outer stainless steel layer from the inside out. A heat-conducting liquid channel is provided between the inner and outer aluminum layers, and the heat-conducting liquid is filled in the heat-conducting liquid channel. A spout is provided at the water inlet of the constant temperature kettle liner.
[0013] Furthermore, the heat-conducting fluid channel is formed by raised textures protruding from the outer aluminum layer.
[0014] Furthermore, the raised texture is a honeycomb pattern.
[0015] This utility model also relates to a kettle, including an inner liner, an electric heating device at the bottom of the inner liner, a lid and a handle connected to the inner liner, the inner liner being a constant temperature kettle inner liner, the upper part of the constant temperature kettle inner liner having a water inlet and the lower part having a heating element, the constant temperature kettle inner liner having, from the inside out, an inner stainless steel layer, an inner aluminum layer, an outer aluminum layer, and an outer stainless steel layer, a heat-conducting liquid channel being provided between the inner aluminum layer and the outer aluminum layer, the heat-conducting liquid channel being filled with heat-conducting liquid; the constant temperature kettle inner liner having a spout at the water inlet.
[0016] Furthermore, the heat-conducting fluid channel is formed by raised textures protruding from the outer aluminum layer; the raised textures are honeycomb-shaped.
[0017] This utility model is used as a replacement for the inner liner of a conventional thermos kettle, and the usage method is the same, so it will not be described again here.
[0018] The beneficial effects of this invention are as follows: 1. The heat-conducting fluid has a high thermal conductivity, enabling it to absorb a large amount of heat in a short time and rapidly transfer it to the entire inner liner and water. Compared to traditional heating methods, using heat-conducting fluid technology allows the thermostatic kettle to heat water to the set temperature more quickly, greatly saving boiling time and improving efficiency. 2. The heat-conducting fluid undergoes a phase change at a specific temperature, absorbing or releasing a large amount of latent heat. When the water temperature reaches the set temperature, the heat-conducting fluid can absorb or release heat through the phase change process, thereby precisely maintaining the water temperature within a stable range, avoiding large fluctuations in water temperature, and providing users with a consistently suitable water temperature. 3. The inner liner of the thermostatic kettle is manufactured using a multi-layer welded composite material process. This process not only gives the inner liner excellent thermal conductivity, enabling rapid and uniform heat transfer, but also ensures high strength, making it more durable and able to withstand certain pressure and impacts.
