Referring to fig. 4-5, fig. 4 is a cross-sectional view of a window type air conditioner according to some embodiments of the present invention; figure 5 is a cross-sectional view of a volute of some embodiments of the present invention. Specifically, the window type air conditioner comprises a volute 1, a fan 2 and an electric control box 4; the volute 1 comprises a front side plate 11 and a rear side plate 12 arranged at the rear side of the front side plate 11 at intervals in parallel, and an air duct 13 is limited between the front side plate 11 and the rear side plate 12; the rear side plate 12 comprises a first air inlet section 121, a transition section 122 and a first air outlet section 123 which are connected in sequence, and an air outlet 132 is formed between the front end of the first air outlet section 123 and the front side plate 11; the first air inlet section 121 extends vertically, the first air outlet section 123 extends horizontally, and two ends of the transition section 122 are respectively connected with the rear end of the first air outlet section 123 and the top end of the first air inlet section 121; the transition section 122 includes a receding portion 1221 recessed toward the air duct 13 at a position close to the first air intake section 121, and an air inlet 131 is formed in the front side plate 11 opposite to the first air intake section 121; the fan 2 is arranged in the air duct 13 and is positioned between the first air inlet section 121 and the air inlet 131; the electronic control box 4 is disposed outside the transition section 122 and near the relief portion 1221.

It can be understood that the receding portion 1221 at the rear side of the volute 1 forms a space for accommodating the electronic control box 4, so that the electronic control box 4 is prevented from compressing the air duct 13 of the volute 1, the distance between the first air inlet section 121 and the air inlet 131 can accommodate the fan 2 with a larger axial size, and the working capacity of the fan 2 is increased to increase the air output.

Because the window air conditioner is installed at an indoor window, the contact area between the indoor side of the window air conditioner and indoor air is the largest, both the air inlet 131 and the air outlet 132 are located at the front side of the volute 1 (for convenience of explaining the position of each component in the window air conditioner, the indoor side of the window air conditioner is defined as the front side in the embodiment of the utility model), and the air inlet 131 is located below the air outlet 132, so that the refrigerated cold air can descend from the highest position in the room.

In some embodiments of the present invention, the transition section 122 further comprises a drain 1222; the upper end of drainage 1222 links to each other with first air-out section 123, and the lower extreme of drainage 1222 links to each other with the upper end of stepping down portion 1221, and the internal wall of drainage 1222 is the circular-arc of indent for wind channel 13. The inner side of the arc-shaped drainage part 1222 reduces the resistance of the air flow, and avoids the vortex phenomenon when the air in the air duct 13 flows through the transition section 122, thereby reducing the impact of the air on the inner side of the air duct 13 to achieve the purpose of noise reduction.

In some embodiments, the flow guiding portion 1222 and the first air outlet section 123 are integrally formed, such as injection molding or sheet metal stamping, so as to improve the structural strength of the rear side plate 12.

In some embodiments of the utility model, the front side panel comprises: the second air inlet section 111, the second air inlet section 111 is arranged opposite to the first air inlet section 121, and the air inlet 131 is arranged on the second air inlet section 111; and a second air outlet section 112, the second air outlet section 112 and the first air outlet section 123 are disposed oppositely, and the air outlet 132 is formed between the front end of the first air outlet section 123 and the front end of the second air outlet section 112. It can be understood that the second air intake section 111 is relatively parallel to the first air intake section 121 to form an air intake passage, and a fan is disposed in the air intake passage to draw in the external cold air from the air intake 131. The second air outlet section 112 is relatively parallel to the first air outlet section 123 to form an air outlet channel, and the air outlet channel is used for receiving the air flowing in from the air inlet channel and then discharging the air from the air outlet 132.

Further, a distance between the first air inlet section 121 and the second air inlet section 111 is set to D1, a distance between the upper end of the abdicating part 1221 and the second air inlet section 111 is set to D2, and in some embodiments, the relationship between D1 and D2 is: 1 < D1/D2 < 1.5. Since the positioning portion 1221 generates a certain resistance to the flow of the air, noise is generated when the air flows, and the output of the fan 2 is increased. Obtained by measurement of a large amount of test data of the applicant, as shown in table 1 below.

TABLE 1

When the range of D1/D2 is 1-1.5, such as 1, 1.2, 1.3, 1.4, or 1.5, the air output of the air outlet 132 can be effectively increased, and the power of the fan 2 is low and the noise is low. Further, when the range of D1/D2 is 1-1.3, the power of the fan 2 is lower and better, and the noise generated by the airflow is smaller, thereby effectively reducing the energy consumption of the fan 2 and increasing the comfort and the experience of the user. Preferably, in some embodiments, when D1/D2 is 1.2, the power of the fan 2 is low and the noise generated by the airflow is minimal.

In some embodiments of the utility model, the volute 1 further comprises: the bottom end of the first air inlet section 121 and the bottom end of the second air inlet section 111 are both connected to the bottom plate 14, and the front end of the bottom plate 14 protrudes forwards relative to the second air inlet section 111; an installation cavity 15 for installing the evaporator 3 is formed between the front end of the bottom plate 14 and the second air inlet section 111.

In some embodiments, the receding portion 1221 and the first air inlet section 121 are integrally formed, for example, injection molding or sheet metal stamping, so as to improve the structural strength of the rear side panel 12.

In some embodiments of the utility model, the fan 2 is a centrifugal fan.

To sum up, the embodiment of the present invention provides a window type air conditioner, wherein the receding portion 1221 is formed on the rear side plate 12 of the spiral case 1, and the receding portion 1221 forms a space for accommodating the electronic control box 4, so that the electronic control box 4 is prevented from compressing the air duct 13 of the spiral case 1, the distance between the first air intake section 121 and the air intake 131 can accommodate the fan 2 with a larger axial size, and the working capacity of the fan 2 is increased to increase the air output. Meanwhile, the impact of the airflow on the inner side of the air duct 13 is effectively improved through the design of the receding part 1221, and the generation of noise is reduced by reducing the flow speed of the air.
