Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioning technology, in particular to a vertical air conditioner indoor unit. BACKGROUND

[0002] With the development of the times and the progress of technology, users not only expect air conditioners to have faster cooling and heating speeds, but also pay more and more attention to the comfort performance of air conditioners. After the air conditioner is turned on and runs, the user not only feels cool or warm, but also pays more attention to whether the wind feeling experience is comfortable.

[0003] The existing vertical air conditioner indoor unit usually has an air outlet on the front side of the shell, which is mainly used for blowing air forward. A wind guide device, such as a wind guide plate, a swing leaf, etc., is arranged at the air outlet to guide the air upward and downward or left and right, but the guiding effect is general. When it is necessary to guide the airflow at a large angle to the left or right, the air volume is often reduced due to the internal structure limitation of the wind guide device. SUMMARY

[0004] The purpose of the present application is to provide a vertical air conditioner indoor unit to expand its air outlet angle range and ensure that the air volume is not affected.

[0005] A further purpose of the present application is to enrich the air supply mode of the vertical air conditioner indoor unit and provide more choices for users.

[0006] In particular, the present application provides a vertical air conditioner indoor unit, comprising:

[0007] a shell; and

[0008] at least one air supply fan mounted on the shell and partially exposed outside the shell, configured to blow the airflow in the shell to the indoor environment when in operation.

[0009] Optionally, the front wall of the shell has an air outlet portion for outputting the airflow in the shell forward.

[0010] The number of air supply fans is multiple, and each is arranged on the lateral sides of the air outlet portion.

[0011] Optionally, each air supply fan is configured to allow air to be blown in a direction laterally away from the shell.

[0012] Optionally, the number of air supply fans is two and they are vertical cross-flow fans.

[0013] Optionally, the two air supply fans are arranged at the corner portions of the lateral ends of the front side of the shell, so that each air supply fan blows air forward and in a direction laterally away from the shell at the same time.

[0014] Optionally, each of the two corner portions has a vertical slot, and a rear end of the vertical slot extends a rear plate in a transverse central direction of the shell, and the rear plate and a front wall of the shell define an air duct of the cross-flow fan.

[0015] Optionally, the air outlet portion includes at least one air outlet opening in the front wall of the shell.

[0016] Optionally, the air outlet portion includes at least one air outlet opening in the front wall of the shell.

[0017] Optionally, the air outlet portion includes at least one air outlet opening in the front wall of the shell.

[0018] Optionally, the air outlet portion includes at least one air outlet opening in the front wall of the shell.

[0019] Optionally, the air outlet portion includes at least one air outlet opening in the front wall of the shell.

[0020] The vertical air conditioner indoor unit of the present application is provided with air supply fans on the shell, and a part of the air supply fans is exposed outside the shell, so that the air supply fans can function as air outlets and air guiding devices. When the air supply fans are turned on, air can be blown in the preset direction, such as forward blowing, left blowing, right blowing, and oblique blowing. The more the number of air supply fans, the larger the range of air outlet angle. Due to the acceleration effect of the air supply fans, the air volume is not only not reduced, but also increased and adjustable.

[0021] Further, in the vertical air conditioner indoor unit of the present application, the air supply fans are arranged on the transverse sides of the air outlet portion, and can blow air in a direction away from the shell. In this way, when the air outlet portion and the air supply fans on the two sides blow air, air is blown forward, left and right at the same time, so that the wide-angle air supply effect is achieved. When only forward blowing is needed, the air supply fans on the two sides can be turned off. The combination of the air supply fans and the air outlet portion of the present application realizes the combination of the wide-angle air supply mode and the conventional air supply mode. Moreover, since the air supply fans are used for left and right blowing, it is unnecessary to design a transverse air guiding mechanism at the air outlet portion, so that the structure of the air outlet portion is more simple. Finally, due to the simple structure of the air outlet portion and the symmetrical arrangement of the left and right air supply fans, the structure of the vertical air conditioner indoor unit is more coordinated and beautiful.

[0022] The above and other objects, advantages and features of the present application will become more apparent from the following detailed description of specific embodiments thereof, taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

[0033] The embodiment of the present application provides a vertical air conditioner indoor unit, which is an indoor part of a split vertical air conditioner. The air conditioner is used for adjusting indoor air, including adjusting temperature, humidity, air quality of the air, humidifying, dehumidifying, introducing fresh air and the like of the indoor air.

[0034] Figure 1 is a schematic front view of the vertical air conditioner indoor unit of the embodiment of the present application; Figure 2 is Figure 1 is another angle schematic view of the vertical air conditioner indoor unit shown in Figure 3 is a schematic sectional view of the vertical air conditioner indoor unit shown in Figure 1 is a schematic sectional view of the vertical air conditioner indoor unit shown in Figure 4 is Figure 3 is an air flow path schematic view of the vertical air conditioner indoor unit shown in when the air supply fan 60 is closed.

[0035] As shown in Figures 1 to 4 The vertical air conditioner indoor unit of the embodiment of the present application can generally include a shell 10 and at least one air supply fan 60.

[0036] The shell 10 can be a vertical column, which defines an accommodation space for accommodating main components of the vertical air conditioner indoor unit, such as an indoor side heat exchanger 20, a main fan 30, a controller and the like. The shell 10 is formed with an adjusting air flow for adjusting indoor air, or an adjusting air flow introduced from other ways. The adjusting air flow can be a heat exchange air flow in particular, which is used for temperature adjustment of an indoor environment. When the air conditioner is in a cooling mode, the heat exchange air flow is cold air; when the air conditioner is in a heating mode, the heat exchange air flow is hot air. Of course, if the air conditioner has additional adjustment functions such as purification, fresh air, humidification and the like, the adjusting air flow can also include a purification air flow, a fresh air flow, a humidification air flow and the like.

[0037] The number of the air supply fan 60 can be one or multiple. Each air supply fan 60 is mounted on the shell 10 and partially exposed outside the shell 10. For example Figure 2, preferably, the air supply fan 60 is "embedded" on the housing 10, so that the surface exposed outside is flush or close to flush with the outer surface of the housing 10, so that the appearance of the indoor unit is more coordinated and beautiful, and the air supply fan 60 does not protrude or recess from the housing 10, which is very conspicuous. The air supply fan 60 is configured to blow the airflow in the housing 10 to the indoor environment when in operation.

[0038] The conventional indoor unit of the vertical air conditioner usually installs the fan inside the housing 10, so that it is hidden and not visible. The embodiment of the present application is configured with an external air supply fan 60, so that part of the air supply fan 60 is exposed outside the housing 10, so that the external air supply fan 60 can play the function of the conventional air outlet + air guide device. The air supply fan 60 can blow the airflow to the preset direction after being turned on, for example, it can be designed to blow forward, left, right, and obliquely (including left front and right front). It can be seen that the more the number of air supply fans 60, the larger the range of air outlet angle. Since the air outlet side of the air supply fan 60 is directly exposed to the indoor environment, it has less wind loss and stronger directional pointing. More importantly, due to the acceleration effect of the air supply fan 60, the air volume will not only not decrease when blowing left, right, and obliquely, but also will increase, and the air volume can be adjusted by adjusting the fan speed.

[0039] In some embodiments, as shown in Figure 3 The indoor unit of the vertical air conditioner further comprises an indoor-side heat exchanger 20, which is arranged in the housing 10 and used for heat exchange with the airflow entering the housing 10 from the air inlet 11 of the housing 10, so as to form a heat-exchanged airflow. Specifically, the air conditioner can be refrigerated / heated by a vapor compression refrigeration cycle system. The vapor compression refrigeration cycle system mainly comprises an evaporator, a condenser, a compressor, a throttling device, a four-way valve, and the like. When the air conditioner is in refrigeration operation, the indoor-side heat exchanger 20 functions as an evaporator. When the air conditioner is in heating operation, the indoor-side heat exchanger 20 functions as a condenser. The vapor compression refrigeration cycle system switches the flow direction of the refrigerant through the four-way valve to realize the switching between the refrigeration mode and the heating mode. The specific mode is the prior art in the air conditioning field, which need not be described here.

[0040] In some embodiments, as shown in Figure 3 The indoor unit of the vertical air conditioner further comprises a main fan 30. The main fan 30 is arranged in the housing 10 and used for promoting the airflow in the housing 10 to flow to the outside of the housing 10. As shown in Figure 3 The main fan 30 can be a vertical (the axis extends along the up-down direction) cross-flow fan. A cross-flow air duct (not shown) can be formed in the housing 10 to match the cross-flow fan. The main fan 30 is the fan in the conventional indoor unit of the vertical air conditioner, and the air supply fan 60 is an additional auxiliary fan embedded in the housing 10. The rated air volume of the air supply fan 60 should be less than that of the main fan 30.

[0041] In some alternative embodiments, the indoor heat exchanger 20 or the main fan 30 can not be arranged in the shell 10, and cold air / warm air can be directly introduced from other parts of the air conditioner, and the specific implementation manner is well known to those skilled in the art, and thus will not be described here.

[0042] In some embodiments, as shown in Figures 1 to 3 The front wall 101 of the shell 10 has an air outlet portion 12 for outputting the airflow in the shell 10 forward. The plurality of air supply fans 60 are arranged on the left and right sides of the air outlet portion 12 in the transverse direction, which is indicated in the figures and is the left-right direction of the shell 10. The air supply fans 60 arranged in this way can enhance the air supply effect on the left and right sides of the air outlet portion 12, and solve the problem of poor air supply effect on the left and right sides of the existing vertical air conditioner indoor unit.

[0043] Further, each air supply fan 60 can be configured to allow air to be blown away from the shell 10 in the transverse direction. That is, the air supply fan 60 on the left side can blow air to the left side, including to the left front. The air supply fan 60 on the right side can blow air to the right side, including to the right front.

[0044] In this way, when the air outlet portion 12 and the air supply fans 60 on the left and right sides all blow air, air is blown forward, to the left, and to the right at the same time, achieving a wide-angle air supply effect, as shown in Figure 3 When the air conditioner only needs to blow air forward, the air supply fans 60 on the left and right sides can be turned off, and the air is mainly blown forward by the air outlet portion 12, as shown in Figure 4 . Figure 3 and Figure 4 The arrows indicate the direction of the airflow. Of course, it can be understood that when the air supply fan 60 is not running, the airflow blown to the air supply fan 60 will be hindered by the fan wheel (or blade) and cannot be blown out smoothly and in a large amount, but some weak airflow will still pass through the fan wheel (or blade) and be blown out.

[0045] The combination of the air supply fan 60 and the air outlet portion 12 of the embodiment of the present application realizes the combination of the wide-angle air supply mode and the conventional air supply mode. Moreover, since the air supply fans 60 are used to blow air to the left and right, it is not necessary to design a transverse air guide mechanism at the air outlet portion 12, so that the structure of the air outlet portion 12 is more simple. Finally, since the structure of the air outlet portion 12 is simple and the air supply fans 60 on the left and right are symmetrically arranged, the structure of the vertical air conditioner indoor unit is more coordinated and beautiful, and the grade of the product is improved.

[0046] In some embodiments, as shown in Figure 2 and Figure 3As shown, the aforementioned air outlet 12 can include at least one air outlet opening on the front wall 101 of the housing 10. Since the air outlet 12 does not need to be provided with a transverse air guide mechanism, it is not necessary to design the air outlet opening too wide as in the prior art. As shown, the number of air outlet openings can be multiple, and arranged along the transverse direction of the housing 10, so that each air outlet opening is vertically strip-shaped. Such a design makes each air outlet opening narrower, forming a structure similar to an air outlet grille, and there is no need to additionally provide a damper / baffle structure to close the air outlet opening. Alternatively, the air outlet 12 can also be in other forms of grille structure.

[0047] In some embodiments, as shown in Figure 2 and Figure 3 , the number of air supply fans 60 can be two and vertically arranged cross-flow fans, which are vertically strip-shaped and can better match the columnar shape of the housing 10.

[0048] Further, as shown in Figure 2 and Figure 3 , the two air supply fans 60 (cross-flow fans) can be respectively arranged at the corner portions of the housing 10 at the two ends of the front side in the transverse direction (i.e. the front left corner and the front right corner of the housing 10, i.e. the corner portions between the two front walls 101 and the transverse side walls 102). Since the cross-flow fan is columnar and blows air from the peripheral surface, it can blow air in multiple directions at the same time. Therefore, the embodiment of the present application stands the two air supply fans 60 at the two corner portions of the housing 10, so that each air supply fan 60 blows air in the front direction and in the transverse direction away from the housing 10 at the same time. Specifically, the air supply fan 60 on the left side can blow air in the left direction, in the front direction and in the left front direction at the same time. The air supply fan 60 on the right side can blow air in the right direction, in the front direction and in the right front direction at the same time.

[0049] Figure 5 is a schematic view of the indoor unit of the vertical air conditioner shown in Figure 2 ; Figure 6 is a schematic view obtained by cutting the structure shown in Figure 5 with a horizontal cutting plane.

[0050] In some embodiments, as shown in Figure 5 and Figure 6 , the two corner portions respectively have a vertically strip-shaped notch, Figure 6 indicated by the dashed lines, specifically the notch A1B1 and the notch A2B2. That is, a section of the corner portion of the housing 10 is cut off. The rear end of each notch extends a rear plate 103 (A1C1, A2C2) in the transverse central direction of the housing 10, and the rear plate 103 and the front wall 101 (specifically the B1D1 section and the B2D2 section) of the housing 10 define an air duct 15 of the cross-flow fan. The two air ducts are A1C1B1D1 (i.e. the region between the two dashed lines) and A2C2B2D2 (i.e. the region between the two dashed lines) respectively.

[0051] In addition, as shown in Figure 5 The air duct further comprises a top wall 152 and a bottom wall 153, both of which end up with the rotating shaft and motor of the installed cross-flow fan, which will not be described in detail.

[0052] The present embodiment defines the air duct 15 with such a simple structure, so that the air supply fan 60 (cross-flow fan) can normally blow air, and also just makes the air supply fan 60 "embedded" in the corner of the shell 10, providing a containing space for the air supply fan 60, which is a very ingenious design.

[0053] At this point, those skilled in the art should recognize that although the present application has been fully shown and described with reference to a number of exemplary embodiments, many other variations or modifications can be directly determined or deduced from the disclosure of the present application in accordance with the principles of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all such other variations or modifications.
