DETAILED DESCRIPTION

[0035] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, the same numbers refer to the same elements throughout the drawings. The following exemplary embodiments are not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of the present disclosure as detailed in the appended claims.

[0036] At present, after installing a ducted type air conditioner, a fresh air system is usually installed to realize the fresh air function. One way is to use a fresh air system that operates independently of the control logic of the ducted type air conditioner. This fresh air system has a high cost and is limited by the structure of the house. Another way is to mount the fresh air system on the ducted type air conditioner. Although this way reduces the cost of the fresh air system relative to the independent fresh air system, the fresh air system increases the installation volume and is not convenient for installation in a limited space.

[0037] To this end, the present disclosure provides a ducted type air conditioner with a low cost, a small occupied space, and a fresh air function. Referring to Figure 1 and Figure 2 The ducted type air conditioner includes a cabinet 10, a fan assembly 20, and a fresh air inlet duct 30. The cabinet 10 is formed by a plurality of wall panels, Figure 1 The illustrated cabinet 10 omits some wall panels, such as Figure 1 The top wall panel and the front side wall panel shown in the figure are omitted to make the internal structure visible. The cabinet 10 is provided with an indoor air inlet. The indoor air inlet can be arranged on the top wall panel, Figure 1The front side wall plate of the middle cabinet is omitted. The fresh air inlet duct 30 is connected between the cabinet 10 and the outdoor to introduce outdoor air into the cabinet 10, wherein the fresh air inlet duct 30 can be located entirely outside the cabinet 10 or partially extend into the cabinet 10. The fan assembly 20 is arranged in the cabinet 10, and the fan assembly 20 has an air inlet 201. The air inlet 201 can be communicated with the indoor air inlet to be able to communicate with indoor air outside the cabinet 10, that is, the fan assembly 20 can suck indoor air through the air inlet on the cabinet 10, and the fan assembly 20 also has an air outlet 204 to guide the sucked air to be discharged after being treated in a specific area. The air inlet 201 can also be communicated with the fresh air inlet duct 30 to introduce outdoor air into the cabinet 10 by using the original fan assembly 20 of the ducted air conditioner and guide the outdoor air to the indoor by the fan assembly 20. It should be noted that the air inlet 201 is not exclusive in communication with the fresh air inlet duct 30 and the indoor air inlet, that is, the air inlet 201 is not limited to being used only to communicate with the fresh air inlet duct 30 to introduce outdoor air, but can also be used to communicate with the indoor air inlet to introduce indoor air, that is, the fan assembly 20 used in the air conditioning mode can also be used in the fresh air mode.

[0038] According to the above technical solution, the fresh air inlet duct 30 capable of introducing outdoor air is connected between the cabinet 10 of the ducted air conditioner and the outdoor, the indoor air inlet is arranged on the cabinet 10, and the air inlet 201 of the fan assembly 20 in the cabinet 10 can be communicated with the indoor air inlet to realize the air conditioning mode, the air inlet 201 can also be communicated with the fresh air inlet duct 30 to realize the fresh air mode, and the air inlet 201 can be simultaneously communicated with the indoor air inlet and the fresh air inlet duct 30 to simultaneously realize the fresh air mode and the air conditioning mode. The ducted air conditioner with the fresh air function provided by the embodiment of the disclosure can make the air inlet 201 of the fan assembly introduce outdoor air and indoor air, diversify the function of the ducted air conditioner, and save the cost and the occupied space without additionally arranging a fresh air system with a fan and other components.

[0039] Referring to Figure 6 , Figure 8 and Figure 10 , the filter 80 can be arranged in the fresh air inlet duct 30 to filter outdoor air. The fresh air inlet duct 30 can be provided with a mounting groove 31, and the bottom of the mounting groove 31 can be provided with an opening, as shown in Figure 6 , the filter 80 can be inserted into the mounting groove 31 from the bottom of the mounting groove 31 in the direction of the arrow. The filter 80 can be a filter screen.

[0040] Referring to Figure 1As shown, the ducted type air conditioner comprises a heat exchange member 90, and the fan assembly 20 has an air outlet 204 which is connected to the heat exchange member 90, so that the air flow from the indoor or outdoor is blown into the heat exchange member 90 through the air outlet 204 of the fan assembly 20, and then is sent into the indoor through the heat exchange member 90. The heat exchange member 90 includes, but is not limited to, an evaporator.

[0041] The box 10 can be provided with a selection assembly 600 for selectively connecting the air inlet 201 to one of the indoor air inlet and the fresh air inlet duct 30, so as to execute the air conditioning mode when connected to the indoor air inlet and execute the fresh air mode when connected to the fresh air inlet duct 30.

[0042] Referring to Figure 1 , Figure 2 and Figure 5 , the selection assembly 600 can include a blocking member 60 movably arranged in the box 10 and a driving member 64 connected between the box 10 and the blocking member 60 for driving the blocking member 60 to block one of the indoor air inlet and the fresh air inlet duct 30, so as to switch the ducted type air conditioner between the fresh air mode and the air conditioning mode.

[0043] The blocking member 60 can be arranged to slide for switching or can be arranged to rotate for switching, which is not limited in the present disclosure.

[0044] In an embodiment, the blocking member 60 can be rotatably connected to the box 10, and the driving member 64 drives the blocking member 60 to rotate, so that the blocking member 60 rotates to block one of the indoor air inlet and the fresh air inlet duct 30 and rotates to block the other. Figure 5 As shown, the blocking member 60 can be rotatably arranged in the box 10 around a shaft 61. As shown, Figure 5 The box 10 can be provided with a first peg 62, one end of the shaft 61 can be inserted into the first peg 62, the blocking member 60 is fixed with a second peg 63, and the other end of the shaft 61 can be rotatably arranged in the second peg 63. The second peg 63 can be driven to rotate by the driving member 64, so that the blocking member 60 rotates for switching.

[0045] In another embodiment, the blocking member 60 can be slidably arranged in the box 10, and the driving member 64 can drive the blocking member 60 to slide, so that the blocking member 60 slides to block one of the indoor air inlet and the fresh air inlet duct 30 and slides to block the other.

[0046] In the embodiments of the present disclosure, the driving member 64 can be a motor, and a power shaft of the motor can be coaxially fixed with the second peg 63.

[0047] Referring to Figure 1 and Figure 10The ducted air conditioner can comprise a first stop plate 71 configured to limit the position of the blocking member 60 blocking the fresh air inlet duct 30. On the one hand, the first stop plate 71 defines the fully closed position of the blocking member 60 when the blocking member 60 abuts against the first stop plate 71. On the other hand, the first stop plate 71 limits the rotation of the blocking member 60 to prevent the blocking member 60 from rotating too much. Figure 1 and Figure 2 The fresh air inlet 11 is formed in one side wall of the cabinet 10, and the fresh air inlet duct 30 is in communication with the fresh air inlet 11. The blocking member 60 can open and close the fresh air inlet 11.

[0048] Referring to Figure 1 , Figure 2 and Figure 8 The ducted air conditioner can comprise a second stop plate 72 configured to limit the position of the blocking member 60 blocking the indoor air inlet. On the one hand, the second stop plate 72 defines the fully closed position of the blocking member 60 when the blocking member 60 abuts against the second stop plate 72. On the other hand, the second stop plate 72 limits the rotation of the blocking member 60 to prevent the blocking member 60 from rotating too much.

[0049] In the embodiments of the present disclosure, the stop plate can be implemented by a separately arranged structure or can be implemented by using other original structures in the ducted air conditioner. For example, the volute structure of the fan can be used as a stop, or part of the separation assembly described below can be used as a stop. The present disclosure does not limit the specific structure and position of the stop plate.

[0050] In one embodiment, the ducted air conditioner can comprise a first stop plate 71 configured to block the gap between the blocking member 60 and the wall plate on which the fresh air inlet 11 is mounted when the blocking member 60 rotates to the position of blocking the fresh air inlet duct 30. Figure 9 and Figure 10 When the blocking member 60 is in this position, part of the mounting structure of the blocking member 60 (such as the pin column described above) causes a gap between the blocking member 60 and the side plate of the cabinet 10. To ensure the sealing performance when the fresh air inlet 11 is closed as described above, the first stop plate 71 can be arranged at the gap to block the gap. For example, the first stop plate 71 can be arranged around the fresh air inlet 11. The first stop plate 71 can be formed on the cabinet 10 or on the fresh air inlet duct 30. The present disclosure does not limit this. The same structure of the first stop plate 71 can be used as the limiting stop and the blocking stop described above.

[0051] In one embodiment, the ducted air conditioner can comprise a second stop plate 72 configured to block the gap between the blocking member 60 and the wall plate of the cabinet 10 when the blocking member 60 rotates to the position of blocking the indoor air inlet. Figure 7 and Figure 8In the position of the blocking member 60, in order to ensure the smooth rotation of the blocking member 60, a slight gap is usually provided between the upper and lower sides of the blocking member 60 and the wall plates of the cabinet 10. In order to prevent indoor air from being introduced, the gap between the blocking member 60 and the wall plates of the cabinet 10 is blocked by the second baffle 72, for example, the second baffle 72 is arranged on the two wall plates respectively, and the specific position of the second baffle 72 is not limited in the disclosure. The same second baffle 72 of the same structure can be used as the above-mentioned limiting and blocking functions at the same time in the disclosure.

[0052] In the embodiment of the disclosure, referring to Figure 7 to Figure 10 , the first channel 41 and the second channel 42 can be formed in the cabinet 10, and the arrows in the figure show the direction of air flow. As shown in Figure 7 and Figure 8 , the first channel 41 can be connected between the fresh air inlet pipe 30 and the air inlet 201, for outdoor fresh air to enter. As shown in Figure 9 and Figure 10 , the first channel 41 can be connected between the indoor air inlet and the air inlet 201, for indoor air to enter. When the first channel 41 is connected between the indoor air inlet and the air inlet 201, the above-mentioned selection assembly 600 blocks the fresh air inlet pipe 30, and the fan assembly 20 can introduce and exhaust indoor air through the first channel 41; when the first channel 41 is connected between the fresh air inlet pipe 30 and the air inlet 201, the above-mentioned selection assembly 600 blocks the indoor air inlet, and the fan assembly 20 can introduce outdoor air into the indoor through the first channel 41. In short, the first channel 41 in the cabinet 10 of the ducted air conditioner can be selected as a ventilation channel in air conditioning mode or a ventilation channel in fresh air mode according to the needs. In the embodiment of the disclosure, the indoor air inlet and the fresh air inlet pipe 30 can also not be blocked, that is, indoor air and outdoor air can enter the same channel at the same time. In the embodiment of the disclosure, the original channel of the ducted air conditioner is used as the fresh air channel, and no additional fresh air system structure is needed to ensure the size of the ducted air conditioner.

[0053] For example, in one embodiment, referring to Figure 7 and Figure 8, the second passage 42 can be formed in the cabinet 10, the second passage 42 is communicated between the indoor air inlet and the air inlet 201, the fan assembly 20 can introduce and lead out indoor air through the second passage 42, when the first passage 41 is communicated between the fresh air inlet duct 30 and the air inlet 201, the first passage 41 and the second passage 42 can be not communicated with each other. When the first passage 41 is communicated between the fresh air inlet duct 30 and the air inlet 201, the outdoor air is introduced into the first passage 41, to avoid that the first passage 41 mixes indoor air with different temperature from the outdoor air to cause condensate water, the first passage 41 and the second passage 42 are not communicated with each other, for example, the indoor air inlet can be blocked by the blocking assembly 600, that is, the second passage 42 is separated, the condensate water can be avoided, and the resistance to the outdoor air can also be avoided to affect the fresh air efficiency. When the first passage 41 is communicated between the indoor air inlet and the air inlet 201, the first passage 41 and the second passage 42 can be used as a passage for introducing indoor air.

[0054] Specifically, the cabinet 10 can be provided with a separation assembly 50, referring to Figure 7 , the separation assembly 50 is configured to separate the first passage 41 and the second passage 42 at least when the first passage 41 is communicated between the fresh air inlet duct 30 and the air inlet 201, so as to prevent indoor air and outdoor air from being mixed in the fresh air mode.

[0055] Referring to Figure 7 to Figure 10 , the fan assembly 20 can include a fan wheel 202 and a volute 203 arranged on the outer periphery of the fan wheel 202, and the separation assembly 50 includes a separation plate arranged in the circumferential direction of the volute 203, such as Figure 3 and Figure 4 , the separation plate is blocked between the wall plate of the cabinet 10 surrounding the rotation axis of the fan wheel 202 and the volute 203, so as to separate the first passage 41 and the second passage 42 in the left-right direction of the drawing. Figure 7 to Figure 10

[0056] In the embodiment of the present disclosure, referring to Figure 7 to Figure 10 , the fan assembly 20 can have a plurality of air inlets 201, and the first passage 41 is arranged between the fresh air inlet duct 30 and at least one air inlet 201, for example, in the embodiment shown in Figure 7 to Figure 10 , in the case of having four air inlets 201, the first passage 41 can be arranged only between the fresh air inlet duct 30 and one air inlet 201, and in other embodiments, in addition to the first passage 41 and the fresh air inlet duct 30 being arranged on the left side in the drawing, the same structure can also be arranged on the right side, that is, the first passage 41 is arranged at two air inlets to increase the fresh air efficiency.

[0057] In the embodiment of the present disclosure, the fan assembly 20 can include at least one double-suction fan, such as Figure 7 and Figure 9 ​In some embodiments, the air supply system 200 can include two double suction fans, each double suction fan including two air inlets 201 to increase the air induction efficiency.

[0058] In the detailed description above, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration specific aspects in which the disclosure can be practiced. In this regard, directional terminology, such as “central,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” “circumferential,” and the like, are used herein to merely describe the orientation in use and / or position of the components being described. As used herein, these directional terms are used in the context of the particular orientation as shown in the figures and are not intended to be a limitation of the disclosure. It is to be understood that the aspects described can be utilized in other orientations, and that structural or logical changes can be made without departing from the concepts of the present disclosure. The following detailed description is, therefore, not to be taken in a limiting sense.

[0059] It is to be understood that the features of the various aspects of the disclosure described herein can be combined with each other, unless specifically noted otherwise. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items; similarly, “at least one of’ includes any and all combinations of one or more of the associated listed items.

[0060] It should be understood that, unless otherwise specifically stated and limited, the terms “joined,” “attached,” “mounted,” “connected,” “linked,” “fixed,” and the like, as used in the embodiments of the disclosure, should be construed broadly, for example, can be fixed connection, can be detachable connection, or integral; can be mechanical connection, can be electrical connection or communication with each other; can be directly connected, can be indirectly connected through an intermediate medium, can be internal connection of two elements or interaction relationship between two elements, unless otherwise specifically limited. The specific meaning of the above terms in this paper can be understood according to the specific circumstances by those skilled in the art.

[0061] Further, the word "over" used in the context of a component, an element, or a material layer "over" another component, an element, or a material layer means that the component, element, or material layer is positioned, for example, placed, formed, deposited, etc. "indirectly" over the other component, element, or material layer such that one or more additional components, elements, or layers are arranged between the component, element, or material layer and the other component, element, or material layer. However, the word "over" used in the context of a component, an element, or a material layer "over" another component, an element, or a material layer also can optionally mean that the component, element, or material layer is positioned, for example, placed, formed, deposited, etc. "directly" over the other component, element, or material layer, for example, in direct contact with the other component, element, or material layer.

[0062] Although terms such as "first," "second," and "third" can be used herein to describe various elements, components, regions, layers or sections, these elements, components, regions, layers or sections should not be limited to the terms. Instead, these terms are used only to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, the first element, component, region, layer or section mentioned in the examples described herein can also be called the second element, component, region, layer or section without departing from the teachings of the examples. In addition, the terms "first," "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or an indicated number of the technical features. Thus, the features defined with "first," "second" can explicitly or implicitly include at least one of the features. In the description herein, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly specifically limited.

[0063] It will be understood that the spatially relative terms, such as "above," "upper," "below," and "lower," are intended to describe a relative position on the drawings as opposed to an absolute position on the device. These spatially relative terms are intended to encompass different orientations of the device in use or operation, for example, if the device were to be inverted. As such, a component that is described as being "above" or "upward" of another component is intended to encompass both an orientation of the component relative to the other component in which the component is above or upward of the other component, as well as an orientation of the component relative to the other component in which the component is below or downward of the other component. Thus, a component that is described as being "above" or "upward" of another component is intended to encompass both orientations of the component relative to the other component. The device can be otherwise oriented (for example, rotated 90 degrees or at other orientations) and the spatially relative terms used herein interpreted accordingly.

[0064] Furthermore, the word "exemplary" is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the word exemplary is intended to present concepts in a concrete manner. As used in this application, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or". That is, unless specified otherwise, or clear from context, "X employs A or B" is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then "X employs A or B" is satisfied under any of the foregoing instances. In addition, the articles "a" and "an" as used in this application and the appended claims should generally be construed to mean "one or more" unless specified otherwise or clear from context to be directed to a singular form. Thus, use of the articles in this application and the following claims is not limiting.

[0065] Also, although the disclosure has been described with respect to only one or more implementations thereof, those skilled in the art will readily appreciate that other alternatives can be used. It is contemplated that the disclosure can be carried out in other specific ways than those expressly disclosed herein.
