In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the applicability of other processes and/or the use of other materials.
An air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The type of the air conditioner 100 is not particularly limited, and for example, the air conditioner 100 may be a cabinet type or a mobile air conditioner, etc., but is not limited thereto.
As shown in fig. 1 and 2, an air conditioner 100 according to an embodiment of the present invention includes a casing 1 and a heat exchange device 2, wherein a heat exchange air duct 11 is provided in the casing 1, the heat exchange device 2 is provided in the casing 1, and the heat exchange device 2 exchanges heat with an air flow flowing into the heat exchange air duct 11, thereby realizing temperature adjustment of air. The installation position of the heat exchange device 2 is not limited, and may be, for example, in the heat exchange air duct 11, or may be, for example, at an inlet of the heat exchange air duct 11, or the like.
As shown in fig. 1 and 2, the casing 1 is further provided with a fresh air duct 12, where the fresh air duct 12 is used for introducing outdoor fresh air (i.e. air in an outdoor environment) from the outside to the inside, so that the indoor air maintains a fresh oxygen-enriched state, and the comfort of the indoor environment is improved. The casing 1 is provided with an air outlet 10a, and an outlet 110 of the heat exchange air duct and an outlet 120 of the fresh air duct are arranged at the air outlet 10a, so that the air outlet of the fresh air duct 12 and the air outlet of the heat exchange air duct 11 are mixed at the inner side of the air outlet 10a and are jointly sent out through the air outlet 10 a.
Here, it should be noted that, in order to realize that the outlet 110 of the heat exchange air duct and the outlet 120 of the fresh air duct are both disposed at the air outlet 10a, so that the air outlet of the fresh air duct 12 and the air outlet of the heat exchange air duct 11 mix with each other at the inner side of the air outlet 10a and are commonly sent out through the air outlet 10a, the two implementation methods specifically include: one is to arrange the outlet 120 of the fresh air duct in the casing 1 near the air inlet and connect with the outlet 110 of the heat exchange duct (as shown in fig. 1-7), and the other is to connect the outlet 120 of the fresh air duct to the side wall of the outlet section of the fresh air duct 120 (as shown in fig. 8-12).
However, in either way, the outlet 120 of the fresh air duct is located in the casing 1, which is a hidden design, so that the fresh air outlet is prevented from being independently opened on the casing 1, that is, the fresh air duct 12 does not directly supply air to the outside of the casing 1 through the fresh air outlet independently opened on the casing 1, but is mixed with the air flow at the outlet of the heat exchange duct 11 at the air outlet 10a, and is sent out from the air outlet 10a in the form of mixed air.
Therefore, as the air outlet of the fresh air duct 12 and the air outlet of the heat exchange duct 11 are mixed air outlets, the situation that a fresh air outlet is independently formed in the machine shell 1 can be avoided, the number of openings in the machine shell 1 can be reduced, the structural strength of the machine shell 1 is improved, the processing difficulty of the machine shell 1 is reduced, and the appearance of the machine shell 1 is improved.
Moreover, because the fresh air and the heat exchange air are sent out after being mixed, the temperature of the air flow sent out by the fresh air duct 12 is fast close to the temperature of the air flow sent out by the heat exchange air duct 11, so that the problem that two air flows are blown out of the shell 1 independently and cannot be effectively mixed is avoided, and further, the two air flows with larger temperature difference are prevented from being felt by a user, so that the comfort of user experience is improved.
In addition, because the fresh air duct 12 and the heat exchange duct 11 mix air at the air outlet 10a, but not mix air at other positions of the heat exchange duct 11, for example, the outlet 120 of the fresh air duct is not communicated with the inlet or the middle part of the heat exchange duct 11, the fresh air flow can be prevented from occupying the volume of the heat exchange duct 11, and the ventilation volume of the heat exchange duct 11 is further ensured to meet the requirement, so that the refrigerating and heating effects of the air conditioner 100 meet the user requirements.
It will be appreciated that the air outlet 10a on the housing 1 may be one or more. For example, when the air outlet 10a is one, the outlet 110 of the heat exchange air duct and the outlet 120 of the fresh air duct may be both disposed at the air outlet 10a, so that the air outlet of the fresh air duct 12 and the air outlet of the heat exchange air duct 11 mix with each other at the inner side of the air outlet 10a and are jointly sent out through the air outlet 10 a; when the air outlets 10a are plural, the outlets 110 of the heat exchange air duct may be disposed at the air outlets 10a, and the outlets 120 of the fresh air duct may also be disposed at the air outlets 10a, so that the air outlet of the fresh air duct 12 and the air outlet of the heat exchange air duct 11 mix with each other at the inner side of each air outlet 10a and are commonly sent out through the air outlet 10 a.
Therefore, according to the air conditioner 100 of the embodiment of the invention, the heat exchange air duct 11 and the fresh air duct 12 are arranged in the casing 1, and the outlet 110 of the heat exchange air duct and the outlet 120 of the fresh air duct are both arranged at the air outlet 10a, so that the air outlet of the fresh air duct 12 and the air outlet of the heat exchange air duct 11 are mixed at the inner side of the air outlet 10a and are jointly sent out through the air outlet 10a, the refrigerating and heating effects of the air conditioner 100 are ensured, meanwhile, the air outlet temperature difference of the air conditioner 100 is avoided, the user comfort is improved, the structural strength of the casing 1 of the air conditioner 100 is conveniently ensured, and the processing procedure of the casing 1 is simplified.
It can be understood that in the process of introducing outdoor fresh air from the outdoor to the indoor through the fresh air duct 12, the outdoor fresh air can be treated and then flows into the indoor, for example, the outdoor fresh air can be purified and then flows into the indoor, so that the cleanness and sanitation of the indoor environment are ensured, and the physical health of a user is ensured; of course, the outdoor fresh air may be subjected to humidification treatment or the like, without being limited thereto.
In some embodiments of the present invention, as shown in fig. 4-7 and 10-12, the air conditioner 100 includes a fresh air fan 31 disposed in the fresh air duct 12, where the fresh air fan 31 operates to drive air in the fresh air duct 12 to flow, so that air in the fresh air duct 12 has a certain pressure and can continuously flow out from an outlet 120 of the fresh air duct, so that the fresh air duct 12 can rapidly and effectively introduce outdoor fresh air from outdoor to indoor, thereby improving the circulation efficiency between indoor environment and outdoor environment, and effectively guaranteeing freshness and oxygen content of indoor environment; moreover, the introduction of the fresh air can be realized without the air supply device 32 arranged corresponding to the heat exchange air duct 11, so that the outdoor fresh air is further ensured to be introduced without influencing the refrigerating and heating effects of the air conditioner 100, and the operation of the fresh air fan 31 is controlled to control the introduction amount of the outdoor fresh air.
The number and type of the fresh air fans 31 are not particularly limited, for example, the fresh air fans 31 may be one or more, and the fresh air fans 31 may be centrifugal fans, axial flow fans, or the like.
In addition, when outdoor fresh air is treated, for example, purified and then flows indoors, the fresh air fan 31 is arranged in the fresh air duct 12, so that the air in the fresh air duct 12 has a certain pressure, the air in the fresh air duct 12 can be effectively ensured to overcome larger resistance to be treated smoothly, the applicability and the practicability of the air conditioner 100 are improved, and the air conditioner 100 is convenient to realize multiple functions.
In a further embodiment of the present invention, as shown in fig. 2, the air conditioner 100 further includes an air guiding device 4, where the air guiding device 4 is disposed at the outlet 120 of the fresh air duct for adjusting the air outlet of the fresh air duct 12, for example, the air guiding device 4 may be used for adjusting at least one of the air outlet direction, the air outlet volume, the air outlet speed, and the like of the fresh air duct 12. Therefore, the air outlet of the fresh air duct 12 is regulated through the air guide device 4, the air mixing effect of the air outlet of the fresh air duct 12 and the air outlet of the heat exchange duct 11 can be regulated, the diversification of the air outlet of the air conditioner 100 can be realized conveniently, and the air conditioner 100 can better meet different requirements of users.
Optionally, as shown in fig. 2, the air guiding device 4 includes an air guiding plate 41 rotatably disposed at the outlet 120 of the fresh air duct, where the air guiding plate 41 can open and close the outlet 120 of the fresh air duct during rotation; when the air deflector 41 opens the outlet 120 of the fresh air duct, the rotation of the air deflector 41 can adjust the air outlet direction of the fresh air duct 12, and the like, thereby adjusting the air mixing effect of the air outlet of the fresh air duct 12 and the air outlet of the heat exchange duct 11. Therefore, the air guide device 4 is simple in structure, convenient to realize and low in cost.
In addition, when the air deflector 41 closes the outlet 120 of the fresh air duct, the air deflector 41 can participate in forming the wall surface of the heat exchange duct 11, so that the air deflector 41 at the position of closing the outlet of the fresh air duct 12 realizes the continuity of the wall surface of the heat exchange duct 11, and the air leakage of the heat exchange duct 11 is avoided, thereby ensuring the air outlet of the air conditioner 100 and further ensuring the refrigerating and heating effects of the air conditioner 100.
Wherein, the air deflector 41 can be one or more; when the number of the air deflectors 41 is multiple, each air deflector 41 can rotate, the air deflectors 41 can be sequentially arranged along the transverse direction of the outlet 120 of the fresh air duct, and the air deflectors 41 can synchronously rotate or can synchronously rotate; but is not limited thereto.
It will be appreciated that the operation of the air deflection 41 may be controlled by a user manual operation and/or the air conditioner 100 itself. For example, when the operation of the air deflector 41 is controlled by manual operation of a user, the user can rotate the air deflector 41 to a proper angle by manually rotating the air deflector 41, so that the air outlet direction and/or the air outlet amount of the fresh air duct 12 can meet the user requirements; when the operation of the air deflector 41 is controlled by the air conditioner 100, the air conditioner 100 may further include a driving component connected to the air deflector 41, and at this time, the air conditioner 100 may control the rotation of the air deflector 41 by controlling the operation of the driving component, so that the air outlet direction and/or the air outlet volume of the fresh air duct 12 may meet the user requirement.
Of course, the air guiding device 4 can also be other devices which can regulate the air outlet of the fresh air duct 12; for example, the air guiding device 4 may include a switch door slidably disposed at the outlet 120 of the fresh air duct to open and close the outlet 120 of the fresh air duct, wherein when the switch door opens the outlet 120 of the fresh air duct, the switch door may adjust the ventilation area of the outlet 120 of the fresh air duct by sliding, thereby adjusting the air outlet of the fresh air duct 12; but is not limited thereto.
In some embodiments of the present invention, the outlet 120 of the fresh air duct includes one or more first outlets 120a, and the first outlets 120a are distributed on at least one of the lateral sides of the heat exchange duct 11. For example, in the examples of fig. 1 and 2, two first outlets 120a may be distributed on two lateral sides of the heat exchange air duct 11, that is, one of the two first outlets 120a is distributed on one of the two lateral sides of the heat exchange air duct 11, and the other is distributed on the other of the two lateral sides of the heat exchange air duct 11, and fresh air flowing out from the two first outlets 120a may be better mixed with air flowing out of the heat exchange air duct 11 at the air outlet 10a, so as to further enhance user experience comfort.
For another example, the first outlet 120a may also be one, and the first outlet 120a may be disposed on one of two lateral sides of the heat exchange air duct 11, so that the fresh air flowing out from the first outlet 120a may be better mixed with the air flowing out of the heat exchange air duct 11 at the air outlet 10 a. Of course, the first outlets 120a may be three or more.

Further, as shown in fig. 4-7, the fresh air duct 12 further includes a second air duct 122, the second air duct 122 is communicated between the fresh air inlet 100b of the air conditioner 100 and the inlet of the first air duct 121, and a fresh air fan 31 is disposed in each second air duct 122, so that outdoor air can flow into the second air duct 122 through the fresh air inlet 100b under the action of the fresh air fan 31 and then flow from the second air duct 122 to the first air duct 121, thereby ensuring that the fresh air duct 12 smoothly introduces outdoor fresh air.
Wherein, second wind channel 122 is one or more and second wind channel 122 distributes in the at least one side in the longitudinal both sides of heat transfer wind channel 11 to the import intercommunication of second wind channel 122 and first wind channel 121, the length of short fresh air wind channel 12 is convenient for the arrangement of fresh air wind channel 12. For example, in the example of fig. 4 to 6, the second air duct 122 is one, and the second air duct 122 is provided at one of both longitudinal sides (e.g., the upper side in fig. 6, or the lower side in fig. 4 and 5) of the heat exchange air duct 11, and the inlet of the first air duct 121 may be located at one of both longitudinal sides of the first air duct 121 such that the inlet of the first air duct 121 is disposed adjacent to the second air duct 122 so that the second air duct 122 communicates with the first air duct 121.
For another example, in the example of fig. 7, two second air channels 122 are provided on both longitudinal sides (e.g., upper and lower sides in fig. 7) of the heat exchange air channel 11, the inlets of the first air channels 121 may be two and the inlets of the two first air channels 121 may be located on both longitudinal sides of the first air channels 121, respectively, the second air channel 122 located on one longitudinal side of the heat exchange air channel 11 communicates with the inlet of the corresponding first air channel 121, and the second air channel 122 located on the other longitudinal side of the heat exchange air channel 11 communicates with the inlet of the corresponding first air channel 121.
It will be appreciated that when the first air duct 121 is one, the inlet of the first air duct 121 may be one or two.

If there is one inlet for each first air duct 121, the inlets of two first air ducts 121 may be located on the same longitudinal side of the heat exchange air duct 11 or on different longitudinal sides of the heat exchange air duct 11, and the number of second air ducts 122 may be one or two. For example, in the examples of fig. 4 to 6, the inlets of the two first air channels 121 are located on the same side in the longitudinal direction of the heat exchange air channel 11, and the second air channel 122 may be one, the second air channel 122 may be located on the same side in the longitudinal direction of the heat exchange air channel 11 as the inlets of the two first air channels 121, and the second air channel 122 is respectively communicated with the inlets of the two first air channels 121; for another example, the inlets of the two first air channels 121 are located at opposite sides of the heat exchange air channel 11 in the longitudinal direction, and two second air channels 122 may be provided at this time, and the two second air channels 122 are respectively communicated with the inlets of the corresponding first air channels 121.
If there are two inlets of the first air channels 121 for each first air channel 121, and the inlets of the two first air channels 121 of each first air channel 121 may be located at two longitudinal sides of the first air channel 121, respectively, then there may be two second air channels 122.
