[0002] Air conditioners are indispensable electrical appliances in people's daily lives and come in a variety of structural forms. With the continuous improvement of industrial design and the application of new technologies, materials, and shapes in air conditioners, not only have various types of air conditioners been developed, but the structure of the indoor unit of air conditioners has also been optimized accordingly.

[0003] Taking the indoor unit of a cabinet air conditioner (referred to as "cabinet unit") as an example, existing cabinet units often only have the form of front air outlet or left and right side air outlet, resulting in a relatively simple air outlet form. This makes the degree of indoor air turbulence relatively low, and it is easy to have stagnant areas, resulting in uneven indoor temperature distribution and affecting the user experience. Utility Model Content

[0004] In view of this, the present invention aims to propose an air conditioner to solve the problem that the air outlet mode of the existing cabinet air conditioner is relatively simple, which easily leads to uneven indoor temperature distribution.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An air conditioner has a left air vent, a right air vent, and a bottom air vent. The working airflow of the air conditioner can flow out from at least one of the left air vent, the right air vent, and the bottom air vent. A circulating fan is provided on the top of the air conditioner to drive indoor air circulation.

[0007] Furthermore, the air conditioner is equipped with a lower fan and a first air inlet channel. The lower fan is located at the bottom of the air conditioner. The air outlet of the first air inlet channel is located above the lower fan and is connected to the air inlet of the lower fan. The air outlet of the lower fan is connected to the lower air outlet.

[0008] Furthermore, a second channel control device is provided at the end of the first air inlet channel near the down fan, which is used to control the on / off flow of the working airflow to the down fan.

[0009] Furthermore, the air conditioner is provided with a left air duct and a right air duct, and a cross-flow fan is installed in both the left air duct and the right air duct; the first air inlet channel is located between the left air duct and the right air duct.

[0010] Furthermore, the air conditioner has only one heat exchanger, and the airflow flowing through the heat exchanger can enter at least one of the left air duct, right air duct, and first air inlet channel.

[0011] Furthermore, a circulating air duct is provided at the top of the air conditioner, and the circulating fan is installed in the circulating air duct.

[0012] Furthermore, the rear air inlet of the circulating air duct is located directly above the air conditioner inlet.

[0013] Furthermore, the front air inlet of the circulating air duct is equipped with a reversing device, which can adjust the orientation of the front air inlet.

[0014] Furthermore, the air conditioner is equipped with a fresh air duct, one end of which is connected to the outdoor environment and the other end is connected to the air inlet of the downdraft fan.

[0015] Furthermore, the fresh air duct is equipped with a first channel control device at one end near the downdraft fan, which is used to control the flow of fresh air to the downdraft fan.

[0016] Compared with the prior art, the air conditioner described in this utility model has the following advantages:

[0017] The air conditioner described in this utility model has three air outlets (left, right, and bottom) in the air conditioner (more precisely, the indoor unit), which enables the air conditioner to achieve multiple air outlet combinations.

Detailed Implementation

[0027] The inventive concepts of this disclosure will be described below using terminology commonly used by those skilled in the art to convey the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. The air conditioners mentioned in this application all refer to the indoor unit. To facilitate differentiation of different airflows, this application uses blue arrows to represent the airflow generated by the circulating fan 1, black arrows to represent the fresh airflow, and red arrows to represent the airflow entering the air conditioner through the heat exchanger 7. (It should be noted that...) Figure 6 The airflow generated by the central circulation fan 1 can be drawn into the air conditioner and pass through the heat exchanger 7, but for the sake of distinction, it is still indicated by a blue arrow.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To address the problem that existing cabinet-style air conditioners often have a limited air outlet configuration, leading to uneven indoor temperature distribution, this embodiment proposes an air conditioner, as shown in the attached diagram. Figure 1-6 As shown, the air conditioner has a left air vent 2 and a right air vent 3, and a bottom air vent 4 is provided at the bottom of the air conditioner. The working airflow of the air conditioner (which can be heating airflow or cooling airflow for ease of description) can flow out from at least one of the left air vent 2, right air vent 3 and bottom air vent 4. A circulating fan 1 is provided on the top of the air conditioner to drive indoor air circulation.

[0031] Therefore, by setting three air outlets (left, right, and bottom) on the air conditioner (more precisely, the indoor unit), this application enables the air conditioner to achieve multiple air outlet combinations. At the same time, by further setting a circulating fan 1 on the top of the air conditioner, the indoor airflow can be quickly disturbed, which greatly improves the degree of indoor air turbulence, effectively avoids the generation of stagnant areas, makes the indoor temperature distribution more uniform, avoids the situation of local temperature being too cold or too hot, and helps to improve the user experience.

[0032] The air conditioner is equipped with a down fan 6 and a first air inlet channel 51. The down fan 6 is located at the bottom of the air conditioner. The air outlet of the first air inlet channel 51 is located above the down fan 6 and connected to the air inlet of the down fan 6. The air outlet of the down fan 6 is connected to the down air outlet 4 (or, the air outlet of the down fan 6 can be regarded as the down air outlet 4). Preferably, the down fan 6 is a centrifugal fan.

[0033] The air conditioner is provided with a left air duct 52 and a right air duct 53. A cross-flow fan is installed in both the left air duct 52 and the right air duct 53. The air outlet of the left air duct 52 is the left air outlet 2, and the air outlet of the right air duct 53 is the right air outlet 3.

[0034] The first air inlet duct 51 is positioned between the left air duct 52 and the right air duct 53 to improve space utilization. Correspondingly, the air inlets of the first air inlet duct 51, the left air duct 52, and the right air duct 53 all face the heat exchanger 7 of the air conditioner, allowing the working airflow to enter the corresponding air duct structure relatively smoothly. Accordingly, a left fan 521 is installed at the air inlet of the left air duct 52, and a right fan 531 is installed at the air inlet of the right air duct 53.

[0035] The air conditioner has only one heat exchanger 7, and the airflow passing through the heat exchanger 7 can enter at least one of the left air duct 52, right air duct 53, and first air inlet channel 51. That is, the left air duct 52, right air duct 53, and first air inlet channel 51 of this application share a single heat exchanger 7. On the one hand, the indoor unit does not need to have an additional heat exchange structure, making the internal layout of the air conditioner more compact, which is beneficial to reducing the number of parts and improving space utilization; on the other hand, refer to the attached... Figure 5 It can be seen that the air inlet of the left air duct 52 faces the left side of the heat exchanger 7, the air inlet of the right air duct 53 faces the right side of the heat exchanger 7, and the air inlet of the first air inlet channel 51 faces the middle of the heat exchanger 7, so that airflow can pass through all areas of the heat exchanger 7, making full use of the heat exchange area of ​​the heat exchanger 7 and improving the heat exchange efficiency of the air conditioner.

[0036] The air conditioner has a circulating air duct 13 at its top, and the circulating fan 1 is installed in the circulating air duct 13. The front air outlet of the circulating air duct 13 is designated as the front air outlet 11, and the rear air outlet of the circulating air duct 13 is designated as the rear air outlet 12. The rear air outlet 12 of the circulating air duct 13 is located directly above the air inlet of the air conditioner. The circulating air duct 13, the first air inlet duct 51, the left air duct 52, and the right air duct 53 are independent of each other.

[0037] The circulating fan 1 can rotate forward or backward. When the circulating fan 1 rotates forward, indoor air can enter the circulating air channel 13 from the rear air vent 12 and then flow out of the circulating air channel 13 from the front air vent 11. When the circulating fan 1 rotates backward, indoor air can enter the circulating air channel 13 from the front air vent 11 and then flow out of the circulating air channel 13 from the rear air vent 12.

[0038] The front air vent 11 can be located on the front panel of the air conditioner housing, on the top cover of the air conditioner, or in the transition structure between the front panel and the top cover of the air conditioner. Accordingly, the front air vent 11 is equipped with a reversing device, which can adjust the orientation of the front air vent 11, such as upward, downward, left front, right front, etc., thereby adjusting the air outlet or intake direction of the circulating fan 1 at the front air vent 11.

[0039] In addition, the air conditioner also has a fresh air function. The air conditioner is equipped with a fresh air duct 61, one end of which is connected to the outdoor environment, and the other end is connected to the air inlet of the lower fan 6. Thus, as the lower fan 6 operates, outdoor air can be delivered into the room. Preferably, the lower fan 6 can be a unidirectional centrifugal fan with one air inlet, allowing both outdoor air and working airflow to enter the air chamber 62 of the lower fan 6 through the same inlet. Alternatively, the lower fan 6 can be a bidirectional centrifugal fan with two air inlets, allowing outdoor air to enter the air chamber 62 of the lower fan 6 through one inlet and working airflow through the other inlet.

[0040] The fresh air duct 61 has a first channel control device 63 at the end near the downdraft fan 6 for controlling the flow of fresh air to the downdraft fan 6. The first air inlet duct 51 has a second channel control device 64 at the end near the downdraft fan 6 for controlling the flow of working air to the downdraft fan 6. The first channel control device 63 and the second channel control device 64 can be baffles or channel valves. For baffle structures, please refer to the attached diagram. Figure 3 One end of the baffle is hinged to the structure at the channel. The baffle can open or close the channel by rotating, thereby realizing the on / off control of the corresponding channel.

[0041] Based on the aforementioned air conditioner, this application further proposes an air outlet method for the air conditioner.

[0042] The method includes an air outlet method for rapid cooling mode, an air outlet method for normal cooling mode, and an air outlet method for heating mode.

[0043] The rapid cooling mode operates as follows: cooling airflow simultaneously exits from the left vent 2, right vent 3, and lower vent 4. The circulating fan 1 rotates clockwise, allowing the air conditioner to provide cooling airflow forward through the three vents. The simultaneous clockwise rotation of the circulating fan 1 directs indoor airflow towards the front of the air conditioner, enhancing airflow circulation and enabling the cool air to quickly fill the room. At this time, the cross-flow fan in the left duct 52, the cross-flow fan in the right duct 53, the lower fan 6, and the circulating fan 1 are all operating. The first channel control device 63 is closed, and the second channel control device 64 is activated.

[0044] In rapid cooling mode, in order to meet the user's need for rapid cooling, the first channel control device 63 is turned off to prevent the down fan 6 from running and sending outdoor air into the room, which would affect the rapid reduction of indoor temperature.

[0045] In normal cooling mode, the airflow method is as follows: cooling air flows out simultaneously from the left vent 2 and the right vent 3, while the circulating fan 1 rotates clockwise. This allows the air conditioner to provide cooling airflow through both vents. The simultaneous clockwise rotation of the circulating fan 1 directs the indoor airflow towards the front of the air conditioner, enhancing airflow circulation and increasing indoor air turbulence, resulting in a more uniform indoor temperature distribution. At this time, the cross-flow fan in the left duct 52, the cross-flow fan in the right duct 53, and the circulating fan 1 are all operating.

[0046] Preferably, the air guide blades at the left air outlet 2 and the right air outlet 3 both guide the air upward, so that the cooling airflow flows towards the front and upper part of the air conditioner. With the convection of "air cooling down and heating up", not only can the air conditioner achieve windless airflow, but also, with the operation of the circulating fan 1 at the top of the air conditioner, the degree of turbulence of the cooling airflow can be further improved, making the indoor temperature distribution more uniform.

[0047] In normal cooling mode, if the user does not require fresh air, the down fan 6 can be kept off, and the first channel control device 63 can also be kept off to prevent hot outdoor air from entering the room and affecting the cooling effect.

[0048] In normal cooling mode, if the user needs fresh air, they can turn on the down fan 6. Correspondingly, at least the first channel control device 63 should be turned on, allowing outdoor air to be delivered into the room through the down vent 4. Of course, the second channel control device 64 is preferably turned off to prevent the cooling airflow from flowing out of the down vent 4, which would affect the user's experience of a draftless environment. If a draftless experience is not a concern, the first channel control device 63 and the second channel control device 64 can be turned on simultaneously, allowing the cooling airflow and outdoor air to enter the air chamber 62 of the down fan 6 and mix. The mixed airflow is then delivered into the room through the down vent 4.

[0049] The air outlet method in heating mode is as follows: heating airflow simultaneously flows out from the left air vent 2, right air vent 3, and lower air vent 4. The circulating fan 1 reverses direction, allowing the air conditioner to provide heating airflow through the three air vents. Simultaneously, the circulating fan reverses direction, allowing the low-temperature air above the air conditioner to flow from the front air vent 11 to the rear air vent 12 of the circulating air duct 13. Since the rear air vent 12 is located directly above the air conditioner's air inlet, more low-temperature air can flow downwards into the air conditioner's air inlet and be heated inside the air conditioner to form heating airflow. This not only improves the heating efficiency of the low-temperature air present in the room but also avoids the stagnation of low-temperature air, resulting in a more uniform indoor temperature distribution. At this time, the cross-flow fan in the left air duct 52, the cross-flow fan in the right air duct 53, the lower fan 6, and the circulating fan 1 are all operating, and the second channel control device 64 is activated.

[0050] Preferably, the air guide blades at the left air outlet 2 and the right air outlet 3 both guide the air downwards, so that the heating airflow flows towards the front and lower part of the air conditioner. At the same time, with the heating airflow flowing out of the lower air outlet 4, the middle and lower part of the room can be heated quickly to meet the user's heating needs in a timely manner. Meanwhile, for the low-temperature air gathered in the upper part of the room, part of it undergoes convection of "air cooling down and heating up", and the other part enters the air conditioner and is heated under the drive and guidance of the circulating fan 1. This allows the low-temperature air in the room to be turned into warm air relatively quickly, which helps to improve the heating efficiency of the air conditioner and enhance the user experience.

[0051] In heating mode, if the user does not require fresh air, the first channel control device 63 can be kept closed to prevent cold outdoor air from being sent into the room by the down fan 6, which would affect the heating effect.

[0052] However, in heating mode, if the user has a need for fresh air, the first channel control device 63 can be turned on to allow the heating airflow and outdoor air to enter the air cavity 62 of the lower fan 6 at the same time and mix. Then the mixed airflow is sent to the room from the lower air outlet 4.

[0053] In this utility model, any air conditioner can include the air conditioner described in this embodiment, and correspondingly, the air outlet method described in this application embodiment can also be used.

[0054] Based on the relevant content provided in this application, the air conditioner also includes conventional indoor unit components such as a base, housing, and electronic control components; similarly, the air conditioner also includes an outdoor unit and related conventional components; since the related conventional components are all prior art, they will not be described in detail here.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
