In order to solve the problems of overcooling / overheating and high noise of the existing cabinet air conditioner when the air supply volume is large, the present invention provides a cabinet air conditioner with side air inlet (hereinafter referred to as cabinet air conditioner) Or air conditioner), in order to reduce the operating noise of the air conditioner while increasing the amount of induced air, breaking the deadlock between the air volume and noise reduction of the traditional air conditioner, and improving the user experience.

As shown in FIG. 1 to FIG. 3, the side-entry cabinet air conditioner 1 of the present invention mainly includes a casing 11 and a jet device 3 installed on the top of the casing 11. The casing 11 is provided with an air return opening 12 and an air supply opening. 13. The casing 11 is provided with a blower 14 and a heat exchanger 15, and the jet device 3 mainly includes a purification unit 33, an air induction unit 31, and a jet unit 32. Referring to FIG. 3 and FIG. 4, the purification unit 33 includes a box body 331 and a purification module 332 provided in the box body 331. The box body 331 is provided with a first air inlet 3311 and a first air outlet (not shown in the figure). The air induction unit 31 includes a pipe body 311. The pipe body 311 has a second air inlet 3111 and a second air outlet (not shown in the figure). The second air inlet 3111 is connected to the first air outlet. The fan 312 and the air induction unit 31 are arranged to be able to introduce the indoor air into the box 331 through the first air inlet 3311, and then pass through the purification module 332 and the pipe 311 in order to be discharged through the second air outlet. Tube body 311. The jet unit 32 includes a cylinder 321 having a third air inlet (not shown) and a third air outlet 3211. The third air inlet is connected to the second air outlet (that is, the left end of the pipe 311 in FIG. 4) (Connected to the side of the cylinder 321), a jet channel 323 is formed between the third air inlet and the third air outlet 3211, and a third air outlet 3211 is provided with an opening and closing mechanism 322 capable of adjusting the air outlet area of the third air outlet 3211 The jet unit 32 is configured to allow the airflow from the air induction unit 31 to flow through the jet channel 323, and then be ejected through the third air outlet 3211 and mixed with the air discharged from the air outlet 13 of the cabinet air conditioner 1.

7 to 9 in combination with FIGS. 1 to 4, wherein FIG. 7 is a schematic diagram of the working principle of the jet device of the present invention; FIG. 8 is a schematic diagram of the working principle of the cabinet air conditioner of the present invention (1); FIG. 9 is Schematic diagram of the working principle of the cabinet air conditioner of the invention (2). When the air conditioner needs a large air volume, the blower 14 and the induced draft fan 312 work at a medium and low speed at the same time. Part of the indoor air is driven by the blower 14 from the side air return port 12 into the cabinet 11 and passes through the heat exchanger 15. The air outlet 13 is sent into the room; another part of the indoor air is driven by the induced draft fan 312 into the cabinet 331 from the first air inlet 3311, and passes through the purification module 332, the pipe 311, and the jet channel 323 in sequence, and then from the third air outlet The 3211 emission is mixed with the wind sent from the air outlet 13 into the room. During the air ejection, the opening and closing mechanism 322 adjusts the air outlet area of the third air outlet 3211, thereby adjusting the air supply volume and air speed of the jet device 3.

From the above description, it can be seen that the cabinet air conditioner 1 of the present invention can mix the indoor air flow emitted by the jet unit 32 with the wind sent from the air outlet 13 during operation, so that the airflow from the air conditioner is softer and the air conditioner is avoided. Many problems such as air-conditioning diseases caused by the supply air being too cold / overheating. By simultaneously starting the induced draft fan 312 and the blower 14 and operating at a low speed, the noise of the air conditioner when the blower 14 is operated at high speed alone can be greatly reduced. The provision of the purification unit 33 enables the jet device 3 to further circulate and purify the indoor air during operation, improves the cleanliness of the indoor air, and reduces floating particles in the air. That is to say, the present invention solves the problems of overcooling / overheating and high noise of the air conditioner when the air conditioner is operated in the prior art, and the jet device 3 has a simple structure and a significant effect, and can not affect the appearance of the air conditioner. At the same time, the air supply volume is increased, and the auxiliary air conditioner is used for cooling / heating, which is suitable for large-scale popularization. Further, the setting of the opening and closing mechanism 322 can adjust the air volume and wind speed of the jet device 3 by adjusting the air outlet area of the third air outlet 3211, so that the air volume, wind speed and temperature of the mixed air can be controlled, which improves the Device usability and user experience.

Next, the jet device of the present invention will be described in detail with reference to FIGS. 3 and 4. As shown in FIG. 3, in a possible implementation manner, the purification component 332 is a filtering structure that can adsorb or decompose harmful gases in the air, such as a HEPA filter or an activated carbon filter, and the HEPA filter usually includes three layers of filtering layers. (Primary filter layer, charged layer, electrostatic dust collection layer), the removal efficiency of particles with a diameter of 0.3 microns or less can reach 99.97% or more.

As shown in FIG. 4, in a possible implementation manner, the pipe body 311 is a substantially circular pipe, a right end thereof is a second air inlet 3111, and a left end thereof is a second air outlet. The induced draft fan 312 is preferably a digital motor. A mounting frame 313 is provided in the tube body 311, and the digital motor is fixedly mounted on the mounting frame 313. The cross-section of the cylinder 321 is annularly arranged, that is, the inner cavity of the cylinder 321 is annular. If the cylinder 321 is referred to as an inner wall inner side, an inner wall outer side, an outer wall inner side, and an outer wall outer side in this order from the inside to the outside in a radial direction, the annular inner cavity is formed by surrounding the outer side of the inner wall and the inner side of the outer wall. One end of the annular inner cavity (the upper end in FIG. 4) is closed by an annular end surface, and the other end (the lower end in FIG. 4) forms a third annular air outlet 3211. A portion surrounded by the inner side of the inner wall forms a cavity that communicates at both ends. 324. The third air inlet is opened on the outer surface of the outer wall. The third air inlet is connected to the second air outlet, and the above-mentioned air guide channel is formed between the third air inlet and the third air outlet 3211. In addition, at the third air outlet 3211, a diversion slope 3212 is also provided along the circumferential direction of the outer surface of the outer wall. The diversion slope 3212 makes the cross-sectional area of the third air outlet 3211 in the direction of the air gradually decrease, that is, The third air outlet 3211 is tapered. In other words, the cross-sectional area of the third air outlet 3211 along the air outlet direction has a tendency to decrease.

Referring to FIG. 5, FIG. 5 is a schematic structural diagram of a digital motor of the present invention. It should be noted that the digital motor (or digital motor) is a fan with high speed and strong suction power. Its maximum speed is close to 110,000 rpm, which is 4-5 times the speed of the ordinary fan motor.

Referring to FIG. 6, FIG. 6 is a schematic structural diagram of an opening and closing mechanism of the present invention. As shown in FIG. 5, in a possible implementation, the opening and closing mechanism 322 is similar to a shutter structure of a camera, and includes a window frame 3221, a plurality of blades 3222 (shown as eight), and a plurality of blades 3222. A moving driving motor (not shown in the figure), the window frame 3221 forms an air outlet, which is directly opposite the third air outlet 3211. A plurality of blades 3222 can be set along the plane in which it is located. The track moves back and forth, thereby adjusting the air outlet area of the third air outlet 3211. Among them, more preferably, the area surrounded by the air outlet of the window frame 3221 is larger than the area surrounded by the outer edge of the outer side of the outer wall at the third air outlet 3211.

Referring back to FIG. 3, the jet device 3 of the present invention includes a purification unit 33, two air induction units 31, and two jet units 32. The two air induction units 31 and two jet units 32 are symmetrically disposed with respect to the casing 331. The second air inlets 3111 of the two air induction units 31 are respectively connected to the two first air outlets of the box 331. The box body 331 is provided with a V-shaped purification module 332, so that after the air enters the box body 331 from the first air inlet 3311, it passes through a part of the purification module 332 and enters the corresponding pipe body 311.

In the control mode, the jet device 3 can be controlled separately. For example, an electric control component (not shown in the figure) is configured inside the casing 331 of the jet device 3, and the electric control component is controlled by a remote controller or using a mobile phone APP; Alternatively, the jet device 3 and the air conditioner may also be controlled in combination. For example, the keys for controlling the jet device 3 are reserved on the air conditioner remote control in advance, and the electric control component is directly connected to the air conditioner reserved interface through the air conditioner remote control. The method realizes the air-to-jet control 3.

The above arrangement has the advantage that, through the setting of the jet device 3, when the air conditioner is running, the induced draft fan 312 and the blower 14 are operated together at a low and medium speed instead of the separate high-speed operation of the blower 14, so that the air flow can be maintained or even increased. In large cases, noise is greatly reduced. Repeated experiments, observations, analysis and comparisons by the inventors have found that for the blower 14, the higher the rotation speed, the greater the noise. When the rotation speed increases near the maximum rotation speed, the noise will appear as the air flow accelerates and the vibration increases significantly. Geometric growth. When the blower 14 and the induced draft fan 312 are operated at the low and medium speeds at the same time, the induced draft fan 312 can share the air supply volume for the blower 14, thereby greatly reducing the high speed operation of the blower 14 in the air conditioner under the premise of providing the same air supply volume. The noise generated guarantees that the operation performance of the air conditioner is unchanged or even improved. The indoor air flow emitted by the jet unit 32 is mixed with the wind sent from the air outlet 13 to make the air conditioner's airflow better and softer, avoiding many problems such as air conditioning diseases caused by the air conditioner's overcooling / overheating. The installation of the purification unit 33 enables the jet device 3 to perform cyclic purification and filtration of indoor air during operation, effectively filtering pm2.5 and other floating particles in the air, and improving indoor air cleanliness. The setting of the opening and closing mechanism 322 can adjust the air volume and wind speed of the jet device 3 by adjusting the air outlet area of the third air outlet 3211, so that the air volume, wind speed, and temperature of the mixed air can be controlled, similar to the structure setting mode of the shutter Therefore, the structure of the opening and closing mechanism 322 is simple and stable, and the "shutter" can be closed when the jet device 3 is not in operation, which plays a role of dust prevention and improves the practicability and service life of the device.

Further, referring to FIGS. 7 and 9, the effective combination of the diversion slope 3212 at the second end of the annular cylinder 321 and the digital motor makes full use of the Venturi effect. When the strong air flow sucked by the digital motor is ejected from the jet channel 323, At the third air outlet 3211, due to the effect of the diversion inclined surface 3212, the airflow instantly increases, the air pressure becomes smaller, and the rapid flow of airflow causes negative pressure near the third air outlet 3211. At this time, the airflow in the cavity 324 and the outside of the cylinder 321 The airflow in the cavity 324 flows through the cavity 324 and the window frame 3221, and the airflow outside the cylinder 321 passes from the ring between the window frame 3221 and the third air outlet 3211 when the blade 3222 is fully opened. After passing through the gap (refer to the dotted arrows in Fig. 7 and Fig. 9), after the two airflows merge with the airflow in the jet channel 323, the airflow is doubled, so that the speed of the digital motor and the blower 14 can be maintained. , Further increase the air volume, or on the premise of ensuring that the air supply volume is unchanged, so that the rotation speed of the digital motor and the blower 14 can be further reduced, and the noise is further reduced.

In addition, since the jet device 3 is disposed on the top of the casing 11, that is, outside the casing 11 of the air conditioner, this also enables the jet device 3 of the present invention to be sold separately, and the user does not need to spend a higher cost to purchase a new low Noise air conditioners, but the jet device 3 can be installed on the air conditioner with only a small purchase cost and modification cost, which greatly expands the application scenario of the present invention and is suitable for large-scale popularization and use.

It should be noted that the above-mentioned preferred embodiments are only for explaining the principle of the present invention, and are not intended to limit the protection scope of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above-mentioned setting methods. So that the present invention can be applied to more specific application scenarios.

For example, in an alternative embodiment, the shapes of the pipe body 311 and the cylinder 321, and the number of the air induction units 31 and the jet units 32 can be adjusted as long as the adjustment can realize the function of the jet device 3. For example, the cross section of the tube body 311 may also be a rectangular tube or another shape of the tube, and the cylinder body 321 may also be in the form of an outer circle, an inner circle, an outer circle, or the like. Has a monolithic cavity. For another example, the jet device 3 may also be provided with only one air induction unit 31 and the jet unit 32. At this time, the installation of the box body 331 may be omitted, and the purification component 332 may be installed in the pipe body 311.

For another example, in another alternative embodiment, the air guide surface at the third air outlet 3211 may also be in another setting form, as long as the setting form can make the cross-sectional area of the third air outlet 3211 along the air outlet direction. It can be gradually reduced. For example, the diversion surface may also be a curved surface, or a combination of an inclined surface and a curved surface, and the diversion surface may be provided around the third air outlet 3211 in a circumferential direction, or may be intermittently disposed along the third air outlet 3211 in a circumferential direction. Even the third air outlet 3211 may not be provided with a diversion slope 3212, and the airflow effect can still be achieved only by the digital motor driving the air flow.

For another example, in another alternative embodiment, the form of the opening and closing mechanism 322, the number of blades 3222, and the like can be adjusted, as long as the opening and closing mechanism 322 can adjust the air outlet area of the third air outlet 3211. . For example, the opening and closing mechanism 322 may also be a hinge type, a curtain type, or the like, and the number of the blades 3222 may be 1 to 10 pieces.

For another example, in another alternative embodiment, the induced draft fan 312 may not use a digital motor, but a common axial fan or a centrifugal fan instead, and the jet function of the present invention may also be implemented.

As another example, in another alternative embodiment, the purification component 332 may also be replaced with other materials, as long as the material can effectively filter out at least a part of harmful substances in the air. For example, the purification component 332 may also be an electrostatic adsorption filter.

Of course, the above-mentioned alternative implementations, as well as the alternative implementations and the preferred implementations, can also be used in cross-cooperation, so as to combine new implementations to be applicable to more specific application scenarios. For example, based on the preferred embodiment, the number of the air induction unit 31 and the jet unit 32 can be reduced to one, and the digital motor can be replaced with an axial fan, so as to form a new embodiment.

A possible work flow of the air conditioner of the present invention is described below with reference to FIGS. 7 to 9 and in combination with FIGS. 1 to 4.

As shown in FIG. 7 to FIG. 9, after the user turns on the air conditioner, the user selects a smaller air supply volume for operation. At this time, the air blower 14 works alone, and the blades 3222 of the opening and closing mechanism 322 are in a closed state, and the jet device 3 is not operated. When the user adjusts the air supply volume to a large air volume, the blower 14 continues to work, and the jet device 3 starts to work: the digital motor is started, the blade 3222 is opened to the maximum, the speed of the digital motor and the blower 14 are maintained at low and medium speeds. At this time, some indoors The air enters the air conditioner through the return air port 12 and is discharged through the air outlet 13 after passing through the heat exchanger 15 and the other part of the indoor air enters the jet device 3 through the first air inlet 3311, and passes through the purification module 332, the pipe body 311, and the jet channel in this order. After 323, the third air outlet 3211 is combined with the air flow discharged from the air outlet 13. While the third air outlet 3211 emits the air flow, the air in the cavity 324 and the air around the cylinder 321 merge with the air flow emitted from the jet channel 323 under the adsorption of negative pressure, and are emitted from the window frame 3221 together.
