Conjunction is not present, also not the present invention claims protection scope within.
The present invention proposes a kind of electric heating tube component and the cabinet air-conditioner with the electric heating tube.
Referring to figs. 1 to Fig. 3, in an embodiment of the present invention, which includes indoor heat exchanger 1, heating tube
2, side stand 3 and electric power connection line 4；Heating tube 2 is fixedly arranged on indoor heat exchanger 1；Side stand 3 is fixedly arranged on indoor heat exchanger 1, and
It is spaced and is arranged with heating tube 2；4 one end of electric power connection line is connect with heating tube 2, and the other end is fixed on side stand 3, and along side stand
3 extend.
Herein it should be noted that, the present embodiment and as Fig. 4 into another embodiment shown in Fig. 8, air conditioner indoor unit
A specially separated floor cabinet air-conditioner.The cabinet air-conditioner generally includes the shell 9 with inner cavity, is equipped in inner cavity various
Component, such as air-supply assembly 8 and the electric heating tube component above air-supply assembly 8, shell 9 is interior to be equipped with air duct (not indicating),
Electric heating tube component and air-supply assembly 8 are set in air duct.Wherein, as shown in figure 3, indoor heat exchanger 1 includes two relative spacings
Heat exchanger plates 11, and between two heat exchanger plates 11 and in the heat exchanger tube 12 of continuous bending setting, circulating in heat exchanger tube 12 has
Refrigerant, air is contacted with indoor heat exchanger 1 occurs heat exchange, to realize the heat transfer process of air conditioner indoor unit.For enhanced room
The heating function in the state of heating of interior heat exchanger 1, usually the rear plate face of heat exchanger 1 is equipped with electric heating module indoors,
The electric heating module includes the heating tube 2 of multiple bending designs and the bracket for fixing electric heating tube 2.And common at present
In product, temperature when being worked due to heating tube 2 would generally reach 200 DEG C or more, but heating tube 2 is usually consolidated by support unit
It is fixed, therefore fixation just not relatively reliable between multiple heating tubes 2；Meanwhile one end of heating tube 2 also leads to electric power connection line 4,
The electric power connection line 4 is also designed without reliable cabling, and also without effective safety clearance between heating tube 2, when power supply connects
When wiring 4 is shaken, electric power connection line 4 just easily collides with the heating tube of high temperature 2 and contacts, to cause security risk.
In addition, shell 9, which is especially between the rear plate face and heating tube 2 of shell 9, should have interval, because shell 9 is usually
Moulding, the setting at the interval can effectively avoid heating tube 2 and melt bad shell 9.Particularly, in the case where unexpected power-off, air-supply
Component can close rapidly, and heating tube 2 can first heat up under the action of waste heat and cool down again, during heating, heating tube 2
Temperature may be more than 250 DEG C, at these elevated temperatures, if being easy to be burned without interval between shell 9 and heating tube 2.In this reality
It applies in example, due to being installed on heat exchanger 1 indoors and the spaced side stand 3 of heating tube 2, and 4 one end of electric power connection line
It being connect with heating tube 2, the other end is fixed on side stand 3, and extends along side stand 3, so, electric power connection line 4 can pass through
The Wiring structure for being fixed on side stand 3 and obtaining safety designs, in this way, it is not only advantageous to the layout of cabling inside beauty, and
And the cabling reliability of electric power connection line 4 can also be turned up, guarantee that electric power connection line 4 is not easy because being easy to shake and apart from heating
Pipe 2 is excessively close and causes to damage or even the high temperature safety accidents such as burn on fire occur.
Specifically, in another embodiment shown in fig. 4 to fig. 6, other than Fig. 1 to structure shown in Fig. 3, side stand
3 were equipped with line card button 33, crossed 33 one end of line card button and connect with side stand 3, and the other end connects to power supply the clamping of line 4.Certainly in
In other embodiments, electric power connection line 4 can also for example, by but the modes such as be not limited to be bonded using glue and realize and be fixed on side
It used the fixed form of line card button 33 not only to have the characteristics that fixation on bracket 3, but in the present embodiment, also had advantageous
It is convenient in subsequent dismounting maintenance etc..Further, as shown in figure 5, the quantity at least two of line card button 33 is crossed, to realize
The multiple spot of electric power connection line 4 is fixed, can further improve cabling reliability.
Herein specifically, be the safety standard cabling for ensuring electric power connection line 4, electric power connection line 4 with it is neighbouring
Heating tube 2 between the minimum range that is spaced be L, wherein the specific formula for calculation of L is as follows:
In formula, I is electric current, and R is resistance, and T is the time, and Pr is Pulan moral number, and d is the caliber of horizontal pipeline, and α changes for convection current
Hot coefficient, λ are the thermal coefficient of air, and g is acceleration of gravity, and υ is the kinematic viscosity of air, and β is the volume expansion system of fluid
Number, Δ t are Excess temperature, and c and n are no unit parameter, when the range of the product of the quasi- number of Ge Laxiaofu and Pulan moral number is 104
~109When, c 0.53, n 1/4, when the range of the product of the quasi- number of Ge Laxiaofu and Pulan moral number is 109~1012When, c is
0.13, n 1/3.It is appreciated that the setting of minimum range L can be prevented because spacing is too small between electric power connection line 4 and heating tube 2
Caused by the generation on fire for the safety accidents such as burning of 4 high temperature of electric power connection line, and the technical solution of the present embodiment can be by making
Electric power connection line 4 is fixed on side stand 3 by used line card button 33, thus control between electric power connection line 4 and heating tube 2 away from
From more than or equal to minimum safe distance L.
Referring to Fig.1 and Fig. 4, in both embodiments, the quantity of side stand 3 is specially two, and two side stands 3 are opposite
Interval setting, heating tube 2 is between two side stands 3；Electric heating tube component further include power shelf 5 and be set to power shelf
