Detailed description of the invention

Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.

Describe the floor air conditioner 100 according to the embodiment of the present invention referring to Fig. 1-Fig. 3, as depicted in figs. 1 and 2, comprise casing 1, spiral case 2, tubular wine wheel 3, heat exchanger 4 and flow guide bar 5 according to the floor air conditioner 100 of the embodiment of the present invention.

Spiral case 2, heat exchanger 4, tubular wine wheel 3, flow guide bar 5 are all located in casing 1.As shown in Figure 1, spiral case 2 has air inlet 21 and air outlet 22, and tubular wine wheel 3 is located in spiral case 2, and the two ends of tubular wine wheel 3 are supported on spiral case 2 all rotationally, and tubular wine wheel 3 is vertically arranged, and namely the rotation of tubular wine wheel 3 is perpendicular to horizontal plane.

As shown in Figure 1, flow guide bar 5 is located on spiral case 2, and flow guide bar 5 is positioned at also contiguous air inlet 21 place, right back of spiral case 2.The rear portion of flow guide bar 5 has the first guide face 51 and the second guide face 52, first guide face 51 and the second guide face 52 are all positioned at the rear of spiral case 2, first guide face 51 and the second guide face 52 extend from front to back toward each other until intersect, namely as shown in Figure 1, first guide face 51 extends towards the second guide face 52 from front to back, and the second guide face 52 extends towards the first guide face 51 from front to back, and the rear edge of the rear edge of the first guide face 51 and the second guide face 52 is intersected.

The left side being all positioned at the second guide face 52 for the first guide face 51 in description is below described, and namely the first guide face 51 is the left surface of flow guide bar 5, and the second guide face 52 is the right flank of flow guide bar 5.

Be understandable that, tubular wine wheel 3 is driven by motor, heat exchanger 4 is positioned at air inlet 21 place, when floor air conditioner 100 works, motor drives tubular wine wheel 3 to rotate, extraneous wind first blow over heat exchanger 4 and and heat exchanger 4 carry out heat exchange after enter tubular wine wheel 3 from air inlet 21 and blow out from air outlet 22 under the effect of tubular wine wheel 3.

When the right back of spiral case 2 and after contiguous air inlet 21 place arranges flow guide bar 5, the wind be positioned on the right side of flow guide bar 5 enters air inlet 21 along the second guide face 52, first guide face 51, the experimental study a large amount of by inventor proves, after this flow guide bar 5 is set, the noise of floor air conditioner 100 obviously reduces, and while reducing noise, air output increases to some extent.

Particularly, the floor air conditioner adopting following configuration is model machine, selecting DC motor Driver tubular wine wheel 3, diameter to be 98 millimeters in this model machine and length is the tubular wine wheel 3 of 835 millimeters, comprises two row U and to manage and often row has the heat exchanger 4 that 20 diameters are the U pipe of 7 millimeters, obtaining following experimental data by adjusting the rotating speed of direct current generator:

Wherein, when in table 1, the data of display are for being unkitted flow guide bar 5, the power of motor under different motor speed, air output and noise data; The data of display in table 2 are after dress flow guide bar 5, the power of motor under different motor speed, air output and noise data.

Can be found out by above-mentioned data: under identical motor speed, the floor air conditioner 100 of flow guide bar 5 is installed compared with the floor air conditioner of flow guide bar 5 is not installed, noise obviously reduces, air output increases and power of motor reduces.

As can be seen from above-mentioned data, be provided with the floor air conditioner 100 of flow guide bar 5 compared with not installing the floor air conditioner of flow guide bar 5, noise reduces about 4.3 decibels, and air output improves about 40 squares ms/min, and energy consumption have dropped about 16 watts.

To sum up, according to the floor air conditioner 100 of the embodiment of the present invention, by in the right back of spiral case 2 and contiguous air inlet 21 place arranges the flow guide bar 5 with the first guide face 51 and the second guide face 52, and make first guide face 51 at the rear portion being positioned at flow guide bar 5 and the second guide face 52 extend to crossing from front to back toward each other, effectively can reduce the noise of floor air conditioner 100, increase air output, reduce energy consumption, thus improve user's experience, reduce customer using cost.

In floor air conditioner 100 of the present invention, the mounting means that flow guide bar 5 is arranged on spiral case 2 does not make particular determination, and such as, in some optional embodiments, flow guide bar 5 can be bonded on spiral case 2, the structural design of flow guide bar 5 and spiral case 2 can both simplify thus, and efficiency of assembling is high; In other optional embodiments, flow guide bar 5 can be connected by buckle with spiral case 2, this connected mode, the setting angle of flow guide bar 5 and installation site can be made more accurate, and installation effectiveness is high.

In floor air conditioner 100 of the present invention, the material of flow guide bar 5 does not also make particular determination, such as, flow guide bar 5 can be foam element or working of plastics, and flow guide bar 5 adopts foam or plastics to make, not only easily shaping, and quality is light, be conducive to the manufacturing cost reducing floor air conditioner 100.

Certainly, as shown in Figure 1, the floor air conditioner 100 of basic inventive embodiments also comprises electric auxiliary thermal 6 and drip tray 7, this electric auxiliary thermal 6 is positioned at air inlet 21 place and in the inner side of heat exchanger 4, one end of heat exchanger 4 is connected with the left side of spiral case 2, the other end of heat exchanger 4 is connected with the right side of spiral case 2, drip tray 7 is connected to one end of heat exchanger 4, the auxiliary thermal 6 of electricity is for heating the wind entered from air inlet 21, when drip tray 7 works for receiving floor air conditioner 100, steam condenses the condensed water got on heat exchanger 4.

Describe in detail referring to Fig. 1 and Fig. 2, the spiral case 2 in floor air conditioner 100 and some preferred embodiments of flow guide bar 5:
