Abstract

The invention relates to the field of household appliances, in particular to a warmer. The warmer comprises multiple cooling fins, the multiple cooling fins sequentially communicate with one another through oil storing cavities to form a circulating channel, the joints of the circulating channel and the oil storing cavities are provided with circulating channel ports, the circulating channel areaof each circulating channel port is S, and each cooling fin is internally provided with at least two oil storing cavities; flow limiting devices are arranged in at least one oil storing cavity of theend cooling fins, flow blocking devices are arranged in at least one other oil storing cavity of the end cooling fins, the flow limiting devices comprise flow limiting structures, the flow limiting structures are used for limiting the circulating channel areas of the oil storing cavities of the adjacent cooling fins and the end cooling fins, and the flow blocking devices are used for isolating theoil storing cavities of the adjacent cooling fins from the oil storing cavities of the end cooing fins; and the circulating channel areas of the flow limiting structures are each between 0.1 S and 0.24 S. According to the warmer, it is guaranteed that a user can not be scalded due to accidental touching, and the using experience of the user is guaranteed.

Description

technical field

[0001] The invention relates to the field of household appliances, in particular to a heater. Background technique

[0002] Existing electric oil heating heaters usually circulate convectively along the heat sink through the heat conduction oil, and the heat is radiated out through the inner wall of the heat sink, thereby heating the space environment. However, the temperature of the back of the heater is very high, and it is easy for the user to accidentally touch it and be scalded when using it. In this regard, the national standard GB4706.23-2007 stipulates that the temperature rise of the metal surface that the heater will touch with the test rod should not exceed 85K. In order to reduce the back temperature of the heater, there are several methods commonly used at present: 1. Print a no-touch sign on the surface of the high-temperature oil circuit. Hidden dangers; 2. Reduce the power of the product. This method is highly safe, but reducing the power of...
