Problems solved by technology

[0003] However, in this existing structure, since the speed of air passing through the heat exchanger 9 is faster at the rear side heat exchanger 9b on the rear panel 4 side, the front side heat exchanger 9a at the main body discharge port 3 side is faster. slower, so the distribution of wind speed is uneven
Therefore, the following problems will occur, that is, the performance of the heat exchanger 9 cannot be brought into full play, and the speed distribution of the air discharged from the main body discharge port 3 to the room is not uniform, and due to the turbulence of the air flow, there will be problems. Such as the problem of condensation at the outlet 3 of the main body during air-conditioning operation

Embodiment 1

[0013] figure 1 It is a side view showing the internal structure of the floor-standing air conditioner in Embodiment 1 of the present invention. Its basic structure is the same as that of the floor-standing air conditioner in the past, and the same parts have adopted the same reference numerals, so the detailed description is omitted.

[0014] Such as figure 1 As shown, a housing 6 is installed on the lower part of the rear panel 4, and the motor 7 is installed inside the housing 6. The motor 7 is supported by the rear panel 4, and the centrifugal fan 8 is attached to the rotating shaft 10 to form an air blower. In addition, the casing 6 is composed of a casing suction port 6 a facing the main body suction port 2 and a casing exhaust port 6 b opening upward. A heat exchanger 9 is further provided above the case 6. The heat exchanger 9 has an inverted V shape and is composed of a front side heat exchanger 9a and a rear side heat exchanger 9b. Therefore, the air sucked in ...

Embodiment 2

[0019] figure 2 It is a side view showing the internal structure of the floor-standing air conditioner in Embodiment 2 of the present invention.

[0020] Such as figure 2 As shown, the upper end portion of the heat exchanger 9 is disposed above the horizontal plane of the lower side 11 constituting the main body discharge port 3 . In addition, similarly to the first embodiment, the heat exchanger 9 is constructed in a convex shape (inverted V-shape) upward from the front panel 5 on the front of the main body to the rear panel 4 on the back of the main body. In addition, the installation of the centrifugal fan 8 and the like is also the same as that of the first embodiment. In this case, contrary to Example 1, the wind speed of the front side heat exchanger 9a located at the obliquely upper part of the centrifugal fan 8 is high, and the wind speed of the rear side heat exchanger 9b is low.

[0021] Therefore, in the present embodiment, the number of arrays of front-side he...

Embodiment 3

[0023] Fig. 3 is a side view showing the internal structure of the floor-standing air conditioner in Embodiment 3 of the present invention. Its basic structure is the same as that of Embodiment 1, so detailed description is omitted.

[0024] In this embodiment, the heat exchanger 9 is provided above the case exhaust port 6b, and the main body exhaust port 3 is provided above the heat exchanger 9. As shown in FIG. In addition, an electric heater 12 serving as an auxiliary heating unit is provided on a horizontal plane higher than the upper end of the heat exchanger 9 and lower than the lower side 11 constituting the main body exhaust port 3 . Therefore, by energizing the electric heater 12 in the flow path where the wind speed is uniformly distributed by the front side heat exchanger 9a and the rear side heat exchanger 9b, air with little temperature unevenness can be discharged from the main body discharge port 3, thereby Realize a comfortable indoor heating space. In additi...

Abstract

A floor-mounted type air conditioner is provided to improve the performance of a heat exchanger by equalizing wind velocity distribution of air passing through the heat exchanger and prevent dew condensation by equalizing wind velocity distribution at a diffuser port. A casing(6) is installed at a lower part of a rear panel(4), containing a motor(7) inside. A ventilating part is formed by supporting the motor by the rear panel and mounting a centrifugal fan(8) at a rotary shaft(10). The casing is formed of a casing suction port(6a) facing a main body suction port(2), and a casing diffuser port(6b) opening upward. A heat exchanger(9) is arranged on the casing in an inverse V shape, wherein the heat exchanger is formed of a rear heat exchanger(9b) and a front heat exchanger(9a) different in the number of accumulated stages.

Description

technical field [0001] The invention relates to a floor-standing air conditioner, in particular to the structure of a heat exchanger. Background technique [0002] Use attached Figure 4 The prior art related to the present invention will be described. Figure 4 It is a side view showing the internal structure of an existing floor-standing air conditioner. The main body 1 of the air conditioner is composed of a main body suction port 2 provided at the lower front part, a main body discharge port 3 provided at the upper front part, a rear panel 4 forming the back side of the main body, and a front panel 5 at the front side of the main body. A case 6 is attached to the lower portion of the rear panel 4 , and a motor 7 is installed inside the case 6 . The motor 7 is supported by the rear panel 4, and the fan 8 is installed on the rotating shaft 10 to form a blower. In addition, the casing 6 is composed of a casing suction port 6 a facing the main body suction port 2 and a cas...
