DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0038] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0039] As described in the background technology, the indoor unit of the existing air conditioner includes an air conditioner body and a fresh air module. The fresh air module is arranged in the shell of the air conditioner body and has a fresh air path independent of the heat exchange air path of the air conditioner body, that is, the fresh air path and the heat exchange air path are not connected to each other. The fresh air module has a fresh air inlet connected to the outdoor environment and a fresh air outlet connected to the indoor environment and opened on the side of the outlet of the heat exchange air path.

[0040] In this way, the air conditioner body can draw fresh air from the outside through the fresh air module through the fresh air inlet, and use the fresh air module to filter the fresh air outside to remove impurities such as particulate matter mixed in the outdoor air, and then discharge the filtered air into the room through the fresh air inlet, thereby improving the indoor air quality.

[0041] However, when the above-mentioned fresh air module is in use, it can usually only introduce fresh air from the outside, but it is difficult to purify the dirty air in the room.

[0042] To solve the above problems, the present application provides an air-conditioning indoor unit and an air conditioner. The air-conditioning indoor unit opens a first fresh air inlet on the fresh air module, so that the first fresh air inlet and the indoor air inlet are connected through the first installation cavity of the first shell of the air-conditioning indoor unit to realize the circulation and purification of indoor air, and eliminates the need to set up air duct pipelines, and the structure is simpler and more compact.

[0043] The following is a detailed introduction to various possible implementation forms of the air-conditioning indoor unit and the air-conditioner provided in the present application in combination with specific implementation methods.

[0044] On the one hand, referring to Figures 1 to 3 As shown, an embodiment of the present application provides an air-conditioning indoor unit, including an air-conditioning body 100, a fresh air module 200 and a first air duct member 213, the air-conditioning body 100 includes a first shell 110, the first shell 110 has a first installation cavity 120, the first shell 110 is provided with an indoor air inlet 1121 and at least one indoor air outlet, the indoor air inlet 1121 and the indoor air outlet are connected to the first installation cavity 120.

[0045] The fresh air module 200 is located in the first installation cavity 120, and has a first fresh air inlet 211 and a fresh air outlet. The first fresh air inlet 211 is connected to at least one indoor air inlet through the first installation cavity 120, and the fresh air outlet is connected to at least one indoor air outlet.

[0046] It can be understood that the air conditioner body 100 can be any one of a vertical air conditioner, a wall-mounted air conditioner or a ceiling air conditioner. In this application, the structure and principle of the air conditioner indoor unit are explained using a vertical air conditioner as an example, without limiting the specific structure of the air conditioner body 100.

[0047] The first shell 110 of the air conditioner body 100 has a first installation cavity 120 therein. The installation cavity 120 can be used only for installing the fresh air module 200 and is located at the lower part of the air conditioner body 100 as a whole.

[0048] In addition, the air conditioner indoor unit provided in this embodiment should also include a heat exchange module, the first housing 110 also has a second installation cavity 130, the heat exchange module is located in the second installation cavity 130, the second installation cavity 130 is separated from the first installation cavity 120, and the first housing 110 is provided with a heat exchange air inlet 1111 and a heat exchange air outlet 1113 connected to the second installation cavity 130. The second installation cavity 130 is used to install the components of the relevant heat exchange module originally used for cooling or heating in the air conditioner body 100, such as an evaporator, a cross-flow fan, etc. The second installation cavity 130 is independent of the first installation cavity 120 through a partition, so that the airflow between the two does not flow. In each embodiment of the present application, the first installation cavity 120 and the second installation cavity 130 are separated from each other as an example for explanation, but the corresponding embodiment formed by the connection between the first installation cavity 120 and the second installation cavity 130 is not excluded.

[0049] A first fresh air inlet 211 is opened on the fresh air module 200 located in the first installation cavity 120, and the first fresh air inlet 211 is connected with the above-mentioned indoor air inlet 1121 through the first installation cavity 120, thereby forming a fresh air inlet channel for taking air from the indoor environment. Therefore, when the fresh air module 200 is running, since the first installation cavity is full of air, the fresh air module 200 can make the polluted air in the room flow into the fresh air module 200 along the indoor air inlet 1121, the first installation cavity 120 and the first fresh air inlet 211 in sequence and be purified and filtered.

[0050] Furthermore, the fresh air module 200 is also provided with a fresh air outlet, and the first housing 110 is provided with at least one indoor air outlet, such as at least one of the first indoor air outlet 1122 and the second indoor air outlet 1112, so that the fresh air outlet is connected with the indoor air outlet. In this way, the indoor air filtered by the fresh air module 200 is discharged into the room again along the fresh air outlet and the indoor air outlet in sequence, thereby realizing the circulation and purification of the indoor dirty air.

[0051] Therefore, the air conditioner indoor unit provided in the embodiment of the present application is provided with an indoor air inlet 1121 on the first shell 110 of the air conditioner body 100, and a first fresh air inlet 211 is provided on the fresh air module 200, and the fresh air module is installed in the first installation cavity 120, so that the first fresh air inlet 211 is connected with the indoor air inlet 1121 through the first installation cavity 120 in the first shell 110. Thus, without the need to provide an indoor air inlet duct component, a connected indoor air inlet channel is formed between the fresh air module 200 and the first shell 110, so as to inhale part of the air in the indoor environment, and discharge the indoor air into the room after purification and filtration, so as to purify the indoor dirty air, and the overall air duct structure is simpler and more compact, and the implementation cost is lower.

[0052] Further, see Figures 1 to 5As shown, the first housing 110 includes a main housing 111 and a rear maintenance plate 112. One side of the main housing 111 is open, and a detachable cover of the rear maintenance plate 112 is disposed on the opening.

[0053] At least one indoor air inlet is disposed on the rear maintenance panel 112 .

[0054] It can be understood that the first shell 110 is formed by the main shell 111 and the rear maintenance plate 112 covering the opening of the main shell 111. The components in the first installation cavity 120 can be inspected and maintained by removing the rear maintenance plate 112. For this purpose, the fresh air module 200 can be arranged in the first installation cavity 120 close to the rear maintenance plate 112 to facilitate the inspection of the fresh air module 200 and make the replacement of the filter element of the fresh air module 200 more convenient and quick.

[0055] Furthermore, the indoor air inlet 1121 is arranged on the rear maintenance plate 112, so that the first fresh air inlet 211 of the fresh air module 200 is connected with the indoor air inlet 1121 on the rear maintenance plate 112 through the installation cavity 120, forming a shorter air path.

[0056] In other embodiments, if the first installation cavity 120 is connected to the second installation cavity 130, the heat exchange air inlet 1111 can also be connected to the first fresh air inlet 211 through the second installation cavity 130 and the first installation cavity 120, so that when the fresh air module 200 draws indoor air, it can not only draw from the indoor air inlet 1121, but also from the heat exchange air inlet 1111, thereby increasing the air intake of the fresh air module 200, and then correspondingly increasing the air outlet of the fresh air module 200, so as to improve the purification efficiency of the fresh air module 200 for the indoor air.

[0057] In specific implementation, refer to Figures 2 to 4 As shown, the first fresh air inlet 211 is located on a side of the fresh air module 200 facing the indoor air inlet 1121 on the rear maintenance plate 112 .

[0058] It can be understood that when the fresh air module 200 is arranged as a whole close to the rear maintenance panel 112, the first fresh air inlet 211 on the fresh air module 200 is directed toward the indoor air inlet 1121, which can further shorten the distance between the first fresh air inlet 211 and the indoor air inlet 1121, so that the fresh air module 200 can draw indoor air from the first indoor air inlet 1121 more smoothly and unobstructedly, and can also make the structure of the indoor air conditioner more compact.

[0059] In some embodiments, reference Figures 1 to 3As shown, two indoor air outlets are provided, including a first indoor air outlet 1122 and a second indoor air outlet 1112 , wherein the first indoor air outlet 1122 is provided on the rear maintenance plate 112 , and the second indoor air outlet 1112 is located on a side of the main shell 111 away from the rear maintenance plate 112 .

[0060] It should be noted that, by providing the first indoor air outlet 1122 and the second indoor air outlet 1112 facing different directions respectively, the air-conditioning indoor unit can deliver fresh air from different directions, thereby improving the indoor air quality more quickly and efficiently.

[0061] Among them, the first indoor air outlet 1122 is arranged on the rear maintenance plate 112, that is, the indoor air inlet 1121 and the first indoor air outlet 1122 are arranged at intervals on the rear maintenance plate 112, so as to make full use of the space on the rear maintenance plate 112. In addition, the indoor air inlet 1121 and the first indoor air outlet 1122 are both air outlet structures in essence, but the airflow directions are different, so they can be formed by one-time processing, making the structure of the air conditioner indoor unit more compact.

[0062] The second indoor air outlet 1112 is located on the side of the main shell 111 away from the rear maintenance panel 112. Normally, the second indoor air outlet 1112 is an outlet of the air conditioner used to directly output fresh air to the user. The air outlet is located on the side of the heat exchange air outlet 1113 for outputting cold air or hot air of the air conditioner, or is arranged around the heat exchange air outlet 1113 for outputting cold air or hot air, so as to improve the air outlet experience. The present application does not impose any restrictions on this.

[0063] In other embodiments, more than two indoor air outlets may be provided on the indoor unit of the air conditioner to deliver fresh air from multiple directions.

[0064] And, refer to Figure 4 and Figure 5 As shown, the first indoor air outlet 1122 and the indoor air inlet 1121 on the rear maintenance plate 112 are arranged at intervals, and the first indoor air outlet 1122 and the indoor air inlet 1121 are both provided with an air guide grille 1123 .

[0065] An air guide grille 1123 is provided on the indoor air inlet 1121 and the first indoor air outlet 1122 which are arranged at intervals, so as to guide the flow direction of the indoor air entering the indoor air inlet 1121 and the indoor air discharged from the first indoor air outlet 1122, thereby preventing the air flow from entering and exiting perpendicularly to the rear maintenance panel 112, thereby affecting the air circulation.

[0066] Specifically, the air guide grille 1123 is set at an angle of 45 degrees upward relative to the extension direction of the air conditioner indoor unit, so that the fresh air module 200 can draw or discharge indoor air upward, which is more conducive to the circulation of indoor air and can prevent ground dust from entering the first installation cavity 120.

[0067] In some other embodiments, reference Figures 3 to 6 As shown, the fresh air module 200 includes a second shell 210 and a second air duct member 214. The second shell 210 has a fresh air cavity (not shown). The first fresh air inlet 211 and the fresh air outlet are both opened on the second shell 210 and connected to the fresh air cavity.

[0068] The fresh air module 200 further has a second fresh air inlet 212 disposed on the second housing 210 . The second fresh air inlet 212 is connected to the outdoor environment via a second air duct 214 .

[0069] The first fresh air inlet 211 and the fresh air outlet are both arranged on the second housing 210 and connected to the fresh air cavity, so that the structure of the fresh air module 200 is simple. In the fresh air cavity, a driving member for driving the air flow and a filter for filtering the air entering the fresh air cavity are arranged. The driving member and the filter can be conventional driving members and filter members in the prior art, and will not be described in detail here.

[0070] A second fresh air inlet 212 is opened on the second shell 210, and the second fresh air inlet 212 is connected to the outdoor environment through the second air duct 214, so that the fresh air module 200 can draw fresh air from the outside and inject it into the fresh air cavity, further improving the air quality of the indoor environment.

[0071] Therefore, a first fresh air inlet 211 and a second fresh air inlet 212 are provided on the second shell 210, so that the fresh air module 200 provided in the present application can draw air from at least one of indoor and outdoor according to usage requirements, and inject it into the indoor environment after filtering and purifying it, and when drawing air from indoor and outdoor at the same time, it can also have a larger air intake volume, thereby making the fresh air output larger.

[0072] Furthermore, in order to achieve separate air intake or mixed air intake through the first fresh air inlet 211 and the second fresh air inlet 212 , an opening regulating valve (not shown) is provided on at least one of the first fresh air inlet 211 and the second fresh air inlet 212 .

[0073] For example, an opening regulating valve is provided on one of the first fresh air inlet 211 and the second fresh air inlet 212 so that one of them is in a normally open state and the opening of the other one is adjustable; or opening regulating valves are provided on both of them so that both can take in air separately or simultaneously.

[0074] The opening regulating valve may be a conventional opening regulating valve separately arranged on the first fresh air inlet 211 or the second fresh air inlet 212, or may be a three-way opening regulating valve arranged between the first fresh air inlet 211 and the second fresh air inlet 212, and the present application does not impose any restrictions on this.

[0075] Among them, refer to Figure 3 and Figure 6 As shown, the first air duct member 213 has an air inlet end and at least one air outlet end 2131, the air inlet end is connected to the fresh air outlet, and each air outlet end 2131 is connected to the indoor air outlet in a one-to-one correspondence.

[0076] By providing the first air duct member 213 , the air flow path of the fresh air module 200 when it is blowing out air can be controlled more accurately.

[0077] In this embodiment, the air inlet end of the first air duct member 213 is connected to the fresh air outlet, and the other two air outlet ends 2131 are respectively connected to the first indoor air outlet 1122 and the second indoor air outlet 1112, so as to realize multi-directional air outlet of the fresh air module 200. In other embodiments, if the air conditioner indoor unit has more than two indoor air outlets, a first air duct member 213 with a corresponding number of air outlet ends 2131 can be provided, so that each air outlet end 2131 is connected to the indoor air outlet one by one.

[0078] On the other hand, an embodiment of the present application provides an air conditioner, comprising an air conditioner outdoor unit and an air conditioner indoor unit in any of the above embodiments, wherein the air conditioner indoor unit and the air conditioner outdoor unit are connected.

[0079] The air conditioner indoor unit has been described in detail in the above embodiments and will not be described again here.

[0080] In summary, the air conditioner indoor unit and the air conditioner provided by the present application are provided with an indoor air inlet 1121 on the first shell 110 of the air conditioner body 100, and a first fresh air inlet 211 is provided on the fresh air module 200, and the fresh air module is provided in the first installation cavity 120 of the first shell 110, so that the first fresh air inlet 211 is connected with the indoor air inlet 1121 through the first installation cavity 120. Thus, when the fresh air module 200 is in operation, it is possible to inhale part of the air in the indoor environment without providing an indoor air inlet duct component, and discharge the indoor air into the room after purification and filtration, so as to purify the indoor dirty air, and the overall air duct structure is simpler and more compact, and the implementation cost is lower.
