Fig. 1 is a schematic front view of a floor air conditioning indoor unit according to an embodiment of the present invention; fig. 2 is a schematic exploded view of the indoor unit of a floor type air conditioner shown in fig. 1. As shown in fig. 1 and 2, the indoor unit of a floor type air conditioner according to the present invention may generally include a cabinet 100, a heat exchanger 200, two cross-flow fans, i.e., a first cross-flow fan 310 and a second cross-flow fan 320, an air duct assembly 400, and an air duct partition 500. In which an accommodating space is defined inside the cabinet 100 to accommodate two cross-flow fans and the heat exchanger 200. The casing 100 includes a front panel 110 located at the front side, and the front panel 110 is provided with a plurality of air outlets 112 arranged vertically. An air inlet 122 is opened at the rear side of the casing 100. Specifically, the rear side of the casing 100 may be an air inlet grille 120, and an air inlet 122 is disposed on the air inlet grille 120. The heat exchanger 200 is disposed in the casing 100, and forms a vapor compression refrigeration cycle system together with the compressor, the condenser, the throttling device, the connecting pipeline, and other accessories, so as to implement refrigeration/heating of the air conditioner.
The first cross flow fan 310 and the second cross flow fan 320 are arranged up and down in the casing 100, and the axes thereof are vertically extended and arranged in a line. The first cross flow fan 310 and the second cross flow fan 320 respectively correspond to a part of air outlets, and are configured to cause air to enter the casing 100 through an air inlet, and to be blown out from the corresponding air outlets after exchanging heat with the heat exchanger 200, so that forced convection heat exchange between indoor air and the heat exchanger 200 is realized, and the heat exchange efficiency of the heat exchanger 200 is improved.
FIG. 3 is a schematic exploded view of the duct divider 500 and bearings of FIG. 2; FIG. 4 is a schematic bottom view of the duct divider 500 of FIG. 3; FIG. 5 is a schematic view of the duct divider 500, bearings, and two cross-flow fans of FIG. 2.
As shown in fig. 2 to 5, the air duct assembly 400 stands outside the first and second cross flow fans 310 and 320 in the circumferential direction, and is used for guiding air from the heat exchanger 200 to the plurality of air outlets 112.
As shown in fig. 2 and 7, the duct assembly 400 includes two end plate portions 430, 440, a volute 410, and a volute tongue 420, which are vertically spaced apart. The driving motor 318 of the first cross flow fan 310 and the driving motor 328 of the second cross flow fan 320 are mounted on the end plate 430 and the end plate 440, respectively. The volute 410 is vertically disposed and connected between the two end plate portions 430 and 440, and the volute tongue 420 is also vertically disposed and connected between the two end plate portions 430 and 440, and guides the air flow direction together with the volute 410. The duct divider 500 is connected between the volute 410 and the volute tongue 420.
The air duct partition 500 is installed on the air duct assembly 400 and located between the first cross flow fan 310 and the second cross flow fan 320 to divide the space defined by the air duct assembly 400 into an upper portion and a lower portion, and is respectively used for accommodating the first cross flow fan 310 and the second cross flow fan 320 to prevent the air supply in the two cross flow fans from interfering with each other. Of course, the above functions can be achieved by directly providing two independent air duct assemblies, but the air duct assembly 400 of the present invention has a simpler structure, and the connection portion between the two cross-flow fans (the portion has no fan and the air flow of the heat exchanger portion opposite thereto is poor) is shorter, which is more advantageous for the heat exchange of the heat exchanger 200.
In addition, two bearings 520 and 550 respectively matched with the rotation shaft 311 of the first cross flow fan 310 and the rotation shaft 321 of the second cross flow fan 320 are installed on the duct partition 500, so that the two cross flow fans can be installed.
An alternative embodiment of the duct divider 500 is shown in fig. 3-5. the duct divider 500 includes a main body portion 510 for dividing the space of the duct assembly 400. The main body 510 has a cylindrical receiving space (see fig. 4) with a downward opening, an opening 513 is formed on the cylindrical receiving space, the bearing 520 is located in the receiving space from below, the opening 513 extends from the upper portion of the bearing, the bearing support 530 supports the bearing 520 below the bearing 520 to keep the bearing at a position, and the bearing support 530 is matched with the clamping hole 512 of the main body 510 through a buckle 532 on the bearing support to complete the installation. The bearing 520 is engaged with the rotation shaft 311 of the first through-flow fan 310. The bearing bracket 540 abuts against the underside of the bearing bracket 520, the bearing 550 is fixed between the bearing bracket 540 and the end plate 560, and the end plate 560 is provided with an opening 563 for allowing the rotation shaft 321 of the second cross flow fan 320 to extend.
In some embodiments, the rated air volume of the first cross flow fan 310 may be greater than the rated air volume of the second cross flow fan 320, so that the total flow area of all the outlets corresponding to the first cross flow fan 310 is greater than the total flow area of all the outlets corresponding to the second cross flow fan 320.
In the embodiment of the invention, the switching of the air supply modes of three air volume gears can be realized only by controlling the opening and closing of two cross-flow fans, and the air volume is from small to sequentially: a mode in which only the second cross flow fan 320 is turned on, a mode in which only the first cross flow fan 310 is turned on, and a mode in which both the first cross flow fan 310 and the second cross flow fan 320 are turned on. And under these three kinds of amount of wind shelves air supply mode, rethread changes cross-flow fan's wind speed, can acquire more diversified air supply mode to satisfy user's different demands, promote user experience.
In addition, the air supply range of the embodiment of the invention is wider (at least in the up-down direction) compared with the prior art in which only one air outlet is arranged at the top of the front side of the air conditioner by arranging the plurality of air outlets 112 in the vertical direction, so that the air supply space of the human body can be basically covered in the vertical direction. Especially, in the heating mode, since the hot wind naturally has an upward trend, if only one air outlet with a higher position is arranged, the hot wind is not convenient to be sent downwards, so that the heating effect of the indoor bottom space is poor. The embodiment of the invention can utilize the lowest air outlet to convey hot air to the bottom space, thereby meeting the heating requirement of the bottom space.
In some embodiments, the first crossflow fan 310 is located above the second crossflow fan 320. Because the rated air volume of the first through-flow fan 310 is larger, when the indoor unit of the vertical air conditioner is started, the refrigerating capacity/heating capacity requirement is large, and the possibility that the first through-flow fan 310 is started is extremely large, so that the first through-flow fan is positioned at the upper side, namely the height of the first through-flow fan is slightly lower than the height of a human body, and air can be conveniently supplied to the space around the human body which needs refrigerating/heating urgently. The second cross flow fan 320 is located at the lower side, corresponds to the air outlet 112 at the lower side, and has a small air volume, and mainly plays a role of assisting the first cross flow fan 310.
In some embodiments, as shown in fig. 1 and 2, three air outlets 112 with the same shape are provided on the front panel 110, and are preferably circular, so as to make the appearance of the indoor unit of the vertical air conditioner more beautiful. Meanwhile, the first cross flow fan 310 corresponds to two of the air outlets 112, and the second cross flow fan 320 corresponds to the other air outlet 112. As described above, if the first cross flow fan 310 is positioned above the second cross flow fan 320, the first cross flow fan 310 needs to be positioned at the two outlets 112 on the upper side, and the second cross flow fan 320 needs to be positioned at the lowest outlet 112. In the embodiment of the invention, the air guiding device 600 can adjust the air outlet directions of the two air outlets 112 corresponding to the first through-flow fan 310, so as to expand the air supply range.
Further, it is preferable that the wind wheel diameters of the first crossflow fan 310 and the second crossflow fan 320 are the same, and the length of the first crossflow fan 310 is twice as long as that of the second crossflow fan 320, so that the rated air volume of the first crossflow fan 310 is twice as large as that of the second crossflow fan 320.
In some alternative embodiments not shown in the drawings, two air outlets 112 may be disposed on the front panel 110, and an area of the air outlet 112 corresponding to the first cross flow fan 310 is twice an area of the air outlet 112 corresponding to the second cross flow fan 320, so that an air blowing mode with multiple air volume levels can be realized.
In some embodiments, as shown in fig. 2, the heat exchanger 200 is preferably a "U" shaped heat exchanger extending vertically and opening forward, and the first cross flow fan 310 and the second cross flow fan 320 are located inside the front of the heat exchanger 200, or two cross flow fans are surrounded by three sides of the "U" shaped heat exchanger, so that when two cross flow fans are in operation, they draw air through the heat exchanger 200 on three sides, thereby increasing the air flow flux of the heat exchanger 200 and further increasing the heat exchange efficiency thereof.
In alternative embodiments, the heat exchanger 200 may also be a flat plate heat exchanger.

Because the embodiment of the present invention provides a plurality of vertically arranged air outlets 112, and the air outlets have a large coverage area in the vertical direction, it is preferable that the swing blades 620 of each swing blade group extend vertically, so that the air outlets can adjust the left and right directions of the air supply during the swing process.
As shown in fig. 7, it is preferable that the scroll case 410 and the scroll tongue 420 are connected to both lateral ends of the frame 610 so as to direct the wind directly to the swing vanes 620 installed on the frame 610, and the flow direction of the wind is shown by arrows in fig. 7.

When the air outlet direction of the air outlet 112 needs to be adjusted, the motor 640 can be controlled to rotate, so that the motor drives the main rocker 630 to swing, the main rocker 630 drives the connecting rod 660 to translate, the connecting rod 660 drives the rockers 630 to swing synchronously, and the rockers 630 drive the swing blades 620 to pivot synchronously. The motor 640 is preferably a stepper motor with better controllability of the rotation process.
Fig. 10 is a schematic structural view of the human body detecting device 800 of fig. 1; fig. 11 is a schematic cross-sectional view of the human body detecting device 800 shown in fig. 10 when mounted on the front panel 110.
As shown in fig. 1, 10 and 11, in some embodiments of the present invention, the indoor unit of a floor air conditioner further includes a human body detection device 800. The human body detection device 800 is configured to detect human body information in a room, the human body information including the number of persons, the temperature of the human body, and the position of the human body. The main control board is configured to control the first cross flow fan 310 and the second cross flow fan 320 to be turned on simultaneously or alternatively according to the human body information, and control the wind speed of the first cross flow fan 310 and the second cross flow fan 320 or the wind direction of the wind outlet 112.
For example, the main control panel can control the on and off of the two cross-flow fans according to the number of people in the room detected by the human body detection device 800. When the number of people is less than m, only the second cross flow fan 320 is started, when the number of people is more than m and less than n, only the second cross flow fan 320 is started, and when the number of people is more than n, the two cross flow fans are started simultaneously. And after one or two cross-flow fans are started, the wind speed can be controlled according to the number of people.
The main control board can also control the opening number or the wind speed of the cross-flow fans according to the human body temperature detected by the human body detection device 800, when the difference between the human body temperature and the human body comfortable temperature is larger, the main control board judges that the human body is hotter or colder, and at the moment, the cross-flow fans can be opened more or the wind speed of the cross-flow fans can be increased so as to accelerate the cooling or heating speed.
The main control board can also control the wind direction of the cross flow fan according to the human body position detected by the human body detection device 800 so as to achieve the effects of cold wind avoiding people and hot wind facing, and the human body is more comfortable.
The specific structure of the human body detection device 800 is shown in fig. 10 and 11. The human body detecting device 800 may include a mounting case 840 having an open front side, a spherical shell 810, a spherical shell driving motor 830, and a temperature and cold sensor 820. Wherein the mounting box 840 is disposed inside the front panel 110. The spherical shell 810 is rotatably disposed in the mounting box 840 about a vertical axis X1, and the front portion thereof protrudes out of the front panel 110 through a circular hole formed in the front panel 110, so as to perform detection. The spherical shell 810 may be formed by splicing two hemispherical shells, and the front side of the spherical shell 810 has an opening 812. The driving motor of the spherical shell 810 is arranged in the mounting box 840 and used for driving the spherical shell 810 to rotate. The thermal sensor 820 is used to detect the aforementioned human body information, and is fixed in the spherical shell 810 with its probe located at the opening to allow light to enter the probe. The temperature-sensitive sensor 820 may be an infrared sensor.
According to the embodiment of the invention, the spherical shell 810 drives the temperature and cold sensor 820 to rotate, so that the detection range can be greatly increased. As shown in fig. 1, the human body detecting device 800 is preferably disposed on the top of the front panel 110, also in order to increase the detection range.
In some embodiments, the human detection device 800 further comprises a hemispherical shutter 850 that is open forward. The hemispherical shielding plate 850 is disposed at the rear side of the spherical shell 810 at a distance from the spherical shell 810, and is fixed to the mounting box 840. The human body detecting device 800 is configured to allow the thermal sensor 820 to detect only the indoor temperature when the spherical shell 810 is rotated to allow the hemispherical shielding plate 850 to completely shield the detection optical path of the thermal sensor 820. That is, when the probe of the thermal sensor 820 is rotated to the rear side, it cannot receive the infrared signal emitted from the human body in the indoor space, so that it only detects the indoor temperature, thereby avoiding erroneous detection.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
