Problems solved by technology

In order to ensure the implementation of the above industry standards, none of the existing electric heating oil heaters can achieve long-term heating at the nominal power, so that the heating elements in the electric heating oil heaters cannot exert their maximum heating effect all the time, and the heating elements cannot The nominal power is maximized, causing a waste of resources and increasing the consumption cost of consumers
[0007] Although the PTC heater can achieve long-term heating at the nominal power, its air supply area is limited, and the internal fan will generate certain noise. The indoor air is very dry during use, and the scope of application is small.
[0008] Although the convection heater can achieve long-term heating at the nominal power, its power is often small, and the speed of air convection is slow. The heating area is still small
[0009] Although the radiant heater can achieve long-term heating with the nominal power, its heating area is small, the indoor air is very dry during use, and there must be light when heating, so the scope of application is small
[0010] Although existing heaters with profile structures can achieve long-term heating with nominal power and have a large heating area, they are heavy and costly
[0011] At present, the electric heating oil heater has become the mainstream product in the heater industry because of its above-mentioned advantages, and is generally accepted by consumers. The pressure is high, so the electric heating oil heater has very high requirements on the sealing of the heat sink, and its welding process is very complicated; the electric heating oil heater meets the design standard that the outer surface temperature rise of the electric heater with a metal outer surface does not exceed 85K, and it is generally used The rear end of the electric heating oil heater is installed on the back cover to prevent the temperature of the heat sink at the rear end from being too high and scalding the human body; in order to prevent the temperature of the electric control components in the front cover of the electric heating oil heater from being too high, it will be installed between the front cover and the heat sink. Insulation layer; a fall switch needs to be set on the electric heating oil to prevent the electric heating element from burning dry and causing danger after it falls; the above-mentioned specific structure of the electric heating oil greatly increases its production cost

Embodiment 1

[0049] see Figure 1 to Figure 7 According to the embodiment of the high-heat anti-scald electric heater provided by the present invention, it includes a heat sink and an electric control assembly arranged at one end of the heat sink. The heat sink includes a plurality of heat sinks 3 connected in sequence, and two adjacent A heat dissipation gap is provided between the heat dissipation fins 3, and the heat dissipation fins 3 include a first heat dissipation single piece 1 and a second heat dissipation single piece 2 that are buckled and connected together, and the first heat dissipation single piece 1 and the second heat dissipation single piece An insulated electric heating flexible wire 5 is provided between the single pieces 2, and a flexible wire channel matching the layout track of the insulated electric heating flexible wire 5 is provided between the first heat dissipation single piece 1 and the second heat dissipation single piece 2 4. The insulated electric heating co...

Embodiment 2

[0065] The structure of this embodiment is substantially the same as that of the first embodiment above, except that the structure of the insulated electric heating cord is different. The insulated electric heating cord includes a wire tube and a resistance wire arranged in the wire tube. The cross-sectional area of ​​the wire is larger than the cross-sectional area of ​​the resistance wire in the second wire segment. The first wire segment and the second wire segment are integrally structured. The insulated electric heating flexible wire of this structure has the advantages of simple structure, few parts, convenient assembly, low production cost, high heating efficiency and high wiring efficiency; the wire tube is made of insulating material, and is safe and reliable during use.

Embodiment 3

[0067] The structure of this embodiment is roughly the same as that of the first embodiment above, except that the structure of the flexible wire channel is different. The low heat channel is distributed on the left and right edges and the upper edge of the heat sink, and the high heat channel is distributed on the heat sink. middle and lower edges. The bottom of the radiating body is provided with a fixed frame, and the setting of the fixed frame makes the lower end of the heat sink untouchable by the human body, and distributes the high heat channel part in the middle and lower edge of the heat sink, prolonging the length of the high heat channel and improving the Product thermal efficiency.

Abstract

The invention provides an anti-scald high-heat electric heater. The anti-scald high-heat electric heater comprises a radiator. The radiator comprises a plurality of cooling fins which are connected in sequence. Each cooling fin comprises a first single cooling fin body and a second single cooling fin body, wherein the first single cooling fin body and the second single cooling fin body are buckled and connected; an insulating electric heating flexible wire is arranged between the first single cooling fin body and the second single cooling fin body, and a flexible wire channel matched with the arrangement track of the insulating electric heating flexible wire is also arranged between the first single cooling fin body and the second single cooling fin body; and the insulating electric heating flexible wire is located in the flexible wire channel, and the flexible wire channel comprises a low-heat channel body and a high-heat channel body communicating with the low-heat channel body. Compared with the prior art, the anti-scald high-heat electric heater provided by the invention has the following advantages that the temperature in the low-heat channel bodies is lower than that in the high-heat channel bodies, and the low-heat channel bodies are close to the edges of the cooling fins so that the temperature rise of the outer surface which can make contact with a human body can be effectively prevented from exceeding the national standard of 85 K, and the situation that the human body is scalded when making contact with the electric heater is avoided.

Description

technical field [0001] The invention relates to an electric heater, in particular to a high-heat anti-scalding electric heater. Background technique [0002] The current electric heaters are roughly divided into the following types: 1. Electric heating oil heaters are generally assembled from multiple heat sinks. At the same time, a cavity is formed in each heat sink, and the heat conduction oil is filled in it. The electric heating element is soaked in heat transfer oil, and the heat is transferred by heating the heat transfer oil. 2. PTC heater It uses the fan to agitate air to flow through the PTC heating element to force convection, which is the main heat exchange method. 3. Convection heater The upper part of the electric heater shell is the air outlet, and the lower part is the air inlet. After the power is turned on, the air around the electric heating tube is heated up and flows out from the air outlet, while the surrounding cold air enters from the air inlet. Sup...
