Description

Vertical air conditioning technology

The present invention is in the field of air conditioning technology and, in particular, relates to a vertical air conditioner.

Background technique

In the existing vertical air conditioner, the air inlet of the indoor unit is usually disposed under the air conditioner front panel and/or the side panel, and an air outlet is arranged above the air conditioner front panel. The indoor air enters the air conditioner from the air inlet and is blown toward the heat exchanger by the centrifugal fan. After heat exchange by the heat exchanger, heat exchange air is formed, and the heat exchanged air is blown out from the air outlet to the room. The amount of air sent from the air outlet of the air conditioner depends entirely on the amount of air entering the air inlet of the air conditioner and the power of the centrifugal fan. It cannot increase the air volume of the air inlet, the air supply volume is limited, and the flow of indoor air is not obvious. Enhancement effect.

At present, there is generally no air inlet on the back panel of the vertical air conditioner. Even if the air inlet is provided, the air inlet is located below the back panel. Moreover, the wind entering from under the back panel is still all heat exchanged through the heat exchanger. Therefore, the air inlet below the back panel plays a role in the air conditioner front panel and/or the side panel. The tuyere is the same, and does not have any effect on the increase in air volume of the air conditioner itself.

In order to increase the air intake of the air conditioner, an air inlet can be opened on the back panel of the air conditioner, and an air-conditioning air supply device having a through air duct is disposed between the air inlet of the back panel and the air outlet of the front panel. The air-conditioning air blower sends a heat exchange air that has been heat-exchanged by the heat exchanger to the air outlet, and a constant negative pressure is formed in the through air passage. Under the action of negative pressure, the non-heat exchanged air in the room enters the through air passage of the air-conditioning air supply device through the air inlet on the rear back plate, and then mixes with the heat exchange air in the through air passage to form a mixed air, together with the air outlet of the front panel. Send it out. Therefore, the air volume sent by the air outlet is equal to the air volume of the heat exchange air and the air volume of the non-heat exchange wind that enters the air inlet of the back panel and does not participate in heat exchange, and the air volume of the air is significantly increased, thereby improving the circulating air volume and the indoor wind. Heat exchange speed. Moreover, the mixed wind formed by the two-part air mixture is soft and the temperature is suitable, especially in the cooling mode, the mixed air temperature is not too low, and it feels comfortable to be blown to the human body.

However, since the air inlet opening on the back panel for introducing additional non-heat exchange air is an open structure, there are the following disadvantages: First, the non-heat exchange wind that cannot enter the back panel cannot be entered. Wind Since the amount is adjusted, the ratio of the heat exchanged air and the non-heat exchanged air contained in the mixed air sent from the tuyere cannot be adjusted. Therefore, the air volume and the outlet air temperature cannot be adjusted according to the individual difference of the user, and the application range is narrow. Secondly, from the user's habits and the comfort to the temperature, in the cooling mode, it is hoped that the cold heat exchange wind energy mixing part will be blown out after the non-heat exchange wind with high temperature; while in the heating mode, it is not desirable. In the heat exchange wind, the non-heat exchanged air with a lower temperature is mixed, that is, the demand for inhaling the non-heat exchanged air in different working modes of the air conditioner is different, and the air inlet of the open structure cannot satisfy the difference between the refrigeration and the heating of the user. Requirements for use in working mode. Thirdly, the rear air inlet of the open structure is easy to cause illusion to the user. It is considered that the speed of air conditioning refrigeration or heating is slower than that of the conventional air conditioner without the rear air inlet, which affects the user's trust in such air conditioner products and reduces the reliability.

Of course, it is also possible to control the baffle 104 to close part of the non-heat exchanged air inlet 1031 by setting corresponding control buttons, that is, to open part of the non-heat exchanged air inlet 1031, so as to pass through the actual air inlet area of the non-heat exchanged air inlet 1031. The amount of non-heat exchanged wind inflow is changed, and then the mixing ratio of the non-heat exchanged wind volume and the heat exchanged wind volume in the mixed wind is adjusted.

Please refer to FIG. 5 to FIG. 7 for another embodiment of the vertical air conditioner of the present invention, wherein FIG. 5 is a partial side cross-sectional structural view of the embodiment, and FIG. 6 and FIG. A perspective view of the non-heat exchanged air inlet state is completely closed. As shown in FIG. 5 to FIG. 7 , the vertical air conditioner of this embodiment includes an indoor unit. The indoor unit includes a front panel 202 , a rear panel 203 , and left and right side panels (not shown), and the front panel 202 and the back panel. The plate 203 and the left and right side panels define the internal air duct of the indoor unit. A circular mixed air outlet 2021 is opened in an upper portion of the front panel 202, and a circular non-heat exchange air inlet 2031 is opened at an upper portion of the air conditioning rear back plate 203 at a position corresponding to the mixed air outlet 2021 on the front panel 202. In the internal air duct, a fan, a heat exchanger (for the existing structure, not shown) and an air-conditioning air supply device 201 are arranged from the bottom, and the fan is arranged such that the air in the air duct of the air conditioner passes through the air-conditioning air supply device. 201 is then blown out from the mixing air outlet 2021 on the front panel 202.

Since the baffle 204 is provided, and the baffle 204 can open or close the non-heat exchanged air inlet 2031, the non-heat exchanged air inlet 2031 can be selectively opened by controlling the position of the baffle 204, so that the non-heat exchange wind can be The air-conditioning air supply device 201 entering the indoor unit from the non-heat exchange air inlet 2031 is further mixed with the heat exchange air entering the air-conditioning air supply device 201 to form a mixed air, and then blown out from the mixed air outlet 2021 on the front panel 202; or, it can be controlled The baffle 204 completely closes the non-heat exchanged air inlet 31 to achieve the same air supply as the existing air conditioning structure and mode. In addition, the baffle 204 can be controlled to block a portion of the non-heat exchanged air inlet 2031, thereby controlling the amount of non-heat exchanged airflow entering the indoor unit from the non-heat exchanged air inlet 2031, thereby realizing heat exchange between the mixed air and the non-heat exchange. The proportion of wind and air volume is adjusted.

In this embodiment, for convenient use by the user, the baffle 204 can open or close the non-heat exchanged air inlet 2031 by a manually controlled curve rotation manner. For the specific implementation structure, please refer to FIG. 6 and FIG. 7 and the following two pairs. Description of the figure.

As shown in FIG. 6 and FIG. 7, a screw hole 2033, a first positioning post 2032 and a second positioning post 2034 are disposed on the back plate 203 in the circumferential direction outside the edge of the non-heat exchanged air inlet 2031. The baffle 204 is provided with a screw hole 2042 corresponding to the screw hole 2033, a groove 2043 corresponding to the first positioning post 2032, and a positioning hole 2041 corresponding to the second positioning post 2034. The first positioning post 2032 is located above the non-heat exchange air inlet 2031, and the screw hole 2033 and the first positioning post 2032 constitute a fixing portion on the back plate 203, respectively, and a screw as a fixed mating portion on the baffle 204. Hole 2042 And the groove 2043 is matched. The second positioning post 2034 serves as a rotating portion on the back plate 203, and is disposed below the non-heat exchange air inlet 2031, and cooperates with the positioning hole 2041 as a rotation fitting portion of the baffle 204. The baffle 204 and the back plate 203 are rotatably assembled by the rotating mating portion and the rotating portion. When the baffle 204 closes the non-heat exchanged air inlet 2031, the baffle 204 and the back plate 203 can pass through the fixed mating portion and the fixing portion. Implement a fixed connection.

Specifically, the positioning hole 2041 of the baffle 204 is sleeved on the second positioning post 2034 on the back plate 203. When the baffle 204 is manually rotated, the baffle 204 will rotate with the second positioning post 2034 as a rotation axis. . If the user does not want to let the non-heat exchange wind participate in the air supply air supply, for example, when the air conditioning operation heating mode is desired, the air conditioning outlet air temperature is high, the baffle 204 can be manually rotated, so that the groove on the baffle 204 The 2043 is rotated to the top and snapped under the first positioning post on the back panel 203. At this time, the screw hole 2042 on the baffle 204 will be aligned with the screw hole 2033 on the back plate 203. Then, a screw is inserted into the screw hole 2042 and the screw hole 2033 to fix the shutter 204 to the back plate 203, thereby exhibiting a structure as shown in Fig. 7. At this time, the baffle 204 completely closes the non-heat exchanged air inlet 2031.

If you want the airflow of the air conditioner to increase, or if you want the air conditioner to send a suitable temperature and gentle mixing air in the cooling mode, you can do the following: First, screw the screws that fix the baffle 204 and the back plate 203 out of the screw holes. 2033 and the screw hole 2042; then, slightly force the groove 2043 on the baffle 204 and the first positioning post 2032 on the back plate 203, so that the baffle 204 under the action of gravity, to locate the hole 2041 and The two positioning posts 2034 naturally hang down from the support points, and assume the state shown in FIG. At this time, the flap 204 completely opens the non-heat exchanged air inlet 2031.

Of course, more corresponding screw holes may be disposed on the back plate 203 and the baffle 204 as fixing holes, and the groove 2043 on the baffle 204 is separated from the first positioning post 2032 on the back plate 203. After that, the baffle 204 is manually rotated to fix the non-heat exchanged air inlet 2031 to the back plate 203 through the screw hole when the rotation angle is less than 180°, so that the baffle 204 can be closed. The wind inlet 2031 is exchanged, that is, a portion of the non-heat exchanged air inlet 2031 is opened. In this case, the actual air inlet area of the non-heat exchange air inlet 2031 can be changed according to different rotation angles of the control baffle 204, and the non-heat exchange air inlet air volume can be changed according to the actual air inlet area, thereby adjusting the non-heat in the mixed air. The ratio of the exchanged wind volume to the heat exchanged wind volume.

In this embodiment, to prevent the shutter 204 from coming off the second positioning post 2034, a sealing cap may be provided at the top end of the second positioning post 2034.

For the vertical air conditioner of the above embodiment, if only the screw holes are formed in the back plate 203 and the baffle 204, if the baffle 204 is screwed to the back plate 203, the non-heat exchanged air inlet 2031 can be completely completed. If the screw is unscrewed and the baffle 204 is detached from the back plate 203, the non-heat exchange air inlet 2031 can be completely opened, so that the baffle 204 can be detachably opened/closed by the non-heat exchange wind. Air inlet 2031. Alternatively, the baffle 204 can be detachably coupled to the back plate 203 in a snap-fit or threaded manner, thereby enabling the baffle 204 to detachably open/close the non-heat exchanged air inlet 2031.

Taking the vertical air conditioner of the first embodiment as an example, a non-heat exchange air inlet 1031 is opened in the indoor unit rear panel 103, and the non-heat exchange air inlet 1031 is opened/closed in a linear push-pull manner for the purpose of adjusting The non-heat exchanged air inlet 1031 enters the non-heat exchanged air volume in the air-conditioning air supply device 101, and further adjusts the air-conditioning air supply air volume and the air supply temperature.

Moreover, for ease of processing, the airflow distribution assembly 1016 is preferably integrally formed with the first intermediate annular air deflector 1013. Of course, it is also possible to split the body, and then the air distribution unit 1016 is mounted and fixed on the first intermediate annular air guiding body 1013.

When the air-conditioning air supply device 101 is assembled into the air conditioner, the rear end annular air guiding body 1012 is fixed to the air conditioning back plate 103, and the first intermediate annular air guiding body 1013 is first fixed to the front end annular air guiding body 1011, and then The front end annular air guiding body 1011 to which the first intermediate annular air guiding body 1013 is fixed is fixed to the front panel 102 of the air conditioner. After being fixed in position, the mixed air outlet 10111 of the front end annular air guiding body 1011 serves as an air outlet of the entire air conditioning air blowing device 101, and will be closedly assembled with the mixed air outlet 1021 on the front panel 102; and in the rear end annular air guiding body 1012 The non-heat exchange air inlet 10122 serves as a non-heat exchange air inlet of the entire air conditioning air blower 101, and is closedly assembled with the non-heat exchange air inlet 1031 on the back panel 103.

In the air conditioner, the air-conditioning air supply device 101 having the above configuration is used, and the baffle 104 is opened to the non-heat exchange air inlet 1031. When the air conditioner is operated, the indoor air enters the indoor unit, and under the action of the fan, the air is accelerated to the heat exchange. The device performs heat exchange. The heat exchanged air after the heat exchange is blown from the internal duct to the air-conditioning air blower 101. The heat exchange wind uniformly enters the first annular heat exchange air duct 1014 and the second annular heat exchange air duct 1015 in the circumferential direction under the distribution of the air distribution unit 1016, and then enters the through wind through the heat exchange air duct. The passage is further blown from the mixed air outlet 10111 on the front end annular wind guide 1011 and the mixed air outlet 1021 on the front panel 102 via the through air passage. Since the speed of the heat exchange wind blown from the annular heat exchange air duct becomes large, the surface pressure of the corresponding annular air deflector is reduced to form a negative pressure in the through air duct, and the indoor air outside the air conditioner is used as a non-heat exchange wind, and is negative. Under the action of the pressure, the opening 1061 on the rear cover 106, the non-heat exchanged air inlet 1031 on the back plate 103 and the non-heat exchanged air inlet 10122 of the rear annular air guiding body 1012 enter the through air passage, and Blowing out of a circular heat exchange wind duct The heat exchange wind forms a mixed air and is sent out to the room together.

After a certain fan speed, the air volume test and the temperature detection of the vertical air conditioner, after the air conditioner air supply device 101 is used, the non-heat exchange air introduced is about 1. 1 times of the heat exchange air volume, and the obtained mixed air volume is The air-conditioning airflow is increased by about 1. 1 times, compared with the air-conditioning air supply of the air-conditioning air supply device 101. Further, if the room temperature is about 28 ° C, the air blown by the air conditioner that does not use the air-conditioning air blower 101 is heat exchanged, and the temperature is about 14 ° C; and after the air-conditioning air blower 101 is used, the air conditioner sends the mixture. The wind is about 19 °C, and the temperature of the mixed wind is more in line with the requirements of human body temperature and temperature comfort. This kind of mixing wind is softer, and it will feel more comfortable when it is blown to the user, which improves the user's comfort experience. Moreover, the air that is not heat-exchanged outside the suction portion is taken into the final air outlet of the air conditioner by the negative pressure generated by the air blowing device 101, thereby increasing the overall air intake of the air conditioner, accelerating the flow of the indoor air, and further improving the air flow. The overall uniformity of the indoor air.

Of course, if the baffle 104 completely closes the non-heat exchanged air inlet 1031, the air conditioning air supply device 101 can only deliver the hot exchange air, and the air supply capability and function are similar to those of the existing air conditioner.

For the specific structure of the air distribution component 1016, please refer to the rear view of FIG. The air distribution assembly 1016 of this embodiment is implemented using a plurality of air distribution plates. The air distribution assembly 1016 of this embodiment includes four pairs of eight air distribution plates, respectively, a main air distribution plate 10161 and 10162, first auxiliary air distribution plates 10163 and 10164, and second auxiliary air distribution plates 10165 and 10166. The third auxiliary air distribution plates 10167 and 10168. All air distribution plates are curved distribution plates with the same bending direction, and the surface of each air distribution plate is curved curved surface, which can effectively guide the wind direction and reduce the pressure loss and noise of the airflow during the shunting process, achieving low High-speed air supply under the premise of noise. The four pairs of air distribution plates are sequentially in the order of the primary air distribution plates 10161 and 10162, the first auxiliary air distribution plates 10163 and 10164, the second auxiliary air distribution plates 10165 and 10166, and the third auxiliary air distribution plates 10167 and 10168. The left and right sides are symmetrically distributed in the circumferential direction of the first annular heat exchange air duct 1014 and the second annular heat exchange air duct 1015. That is, in the direction of the bottom-up heat exchange air supply, the left side of the air-conditioning air supply device 101 (the left and right sides in the rear view direction) is provided with the main air from the bottom up. Flow distribution plate 10161, first auxiliary air distribution plate 10163, second auxiliary air distribution plate 10165 and third auxiliary air distribution plate 10167, and main air distribution plate 10162, first auxiliary air distribution plate 10164, second auxiliary air distribution plate The 10166 and the third auxiliary air distribution plate 10168 are disposed on the right side of the air-conditioning air blower 101 in a bilaterally symmetrical manner. Moreover, the bending direction of each air distribution plate is opposite to the heat exchange air blowing direction. That is, the heat exchange air blowing direction is from bottom to top, and the bending reverse direction of each air distribution plate will be the reverse air blowing direction, that is, the counterclockwise bending as shown in FIG.

By providing the air distribution unit 1016 formed by a plurality of curved air distribution plates arranged radially symmetrically in the heat exchange air duct, the main air distribution plates 10161 and 10162 can be used to divide the heat exchange air from the heat exchanger into left, center and right. In the three parts, the heat exchange winds on the left and right sides can be diverted again by the auxiliary air distribution plates, and finally the uniformity of the air inlet and outlet in the circumferential direction of the heat exchange air duct of the air conditioning air supply device 101 is realized. The air supply uniformity of the air-conditioning air blowing device 101 is improved.

Of course, the air distribution unit 1016 can be implemented in addition to a plurality of curved air distribution plates, and other configurations can be employed as long as it is possible to uniformly distribute the heat exchange air from the heat exchanger in the circumferential direction.
