Description

Technical Field

[0001] This invention relates to the field of heating, ventilation and / or air conditioning systems, and more specifically to a heating, ventilation and / or air conditioning system and a motor vehicle. Background Technology

[0002] With the widespread use of heating, ventilation and / or air conditioning systems in residential and commercial sectors, higher requirements are being placed on these systems, especially those used in motor vehicles.

[0003] Currently, in motor vehicles, heating, ventilation, and / or air conditioning systems typically lack a tiered structure or have only a simple tiered structure. However, the lack of a tiered structure results in only one airflow—either recirculated air or fresh air—entering the air conditioning unit, making it impossible to use different airflow types for the face and feet. While a simple tiered structure allows fresh air and recirculated air to enter the air conditioning unit in layers, the airflow space within the housing is not clearly separated, leading to mixed flow paths for each layer and making it difficult to guide the airflow effectively to its corresponding outlet. Furthermore, the air temperature output from each outlet is difficult to independently regulate and control. On the other hand, considering that heating, ventilation, and / or air conditioning systems are typically installed below the vehicle's dashboard, current systems generally have a large vertical volume, which raises the dashboard after installation, significantly limiting the driver's visibility.

[0004] Therefore, there is a need for a heating, ventilation, and / or air conditioning device that, while providing good heating, ventilation, and / or air conditioning functions, can achieve stratified entry of different airflows, and can effectively separate the flow spaces of each stratified airflow through the cooperation of internal structural components according to actual needs, and allows the air temperature output from each outlet to be independently regulated and controlled. Furthermore, this heating, ventilation, and / or air conditioning device has an ultra-thin design, especially with a small three-dimensional volume in the Z-direction (vertical) direction.

The heating, ventilation, and / or air conditioning device provided by this invention, based on the stratified entry of at least two different airflows, allows for flexible coordination of the internal structure and components under different operating modes. This enables the effective division of the flow space for each stratified airflow according to actual needs, and guides and directs the flow paths of the stratified airflows so that they are output through the target outlet.

[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of the present invention.

[0052] As indicated in this application and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not specifically singular and may include plural forms. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0053] While this application makes various references to certain modules of the systems according to embodiments of this application, any number of different modules can be used and run on user terminals and / or servers. The modules described are merely illustrative, and different aspects of the systems and methods may use different modules.

[0054] Flowcharts are used in this application to illustrate the operations performed by the system according to embodiments of this application. It should be understood that the preceding or following operations are not necessarily performed in exact order. Instead, various steps can be processed in reverse order or simultaneously as needed. Furthermore, other operations can be added to these processes, or one or more steps can be removed from them.

[0055] Figure 1 A perspective view of a heating, ventilation, and / or air conditioning apparatus 100 according to an embodiment of the present invention is shown. Figure 2 A top view of a heating, ventilation, and / or air conditioning unit 100 according to an embodiment of the present disclosure is shown. Figure 3 It shows according to Figure 2 The central axis Oy provides a cross-sectional view of the heating, ventilation and / or air conditioning unit 100.

[0056] Comprehensive reference Figure 1 and Figure 2 The heating, ventilation, and / or air conditioning unit 100 includes, for example, a housing 110 that allows airflow and has a first outlet 160, a second outlet 180, and a layered partition wall 150. Figure 6 The diagram shows a layered partition wall 150. The heating, ventilation, and / or air conditioning unit, for example, has a central axis Oy (in...). Figure 1 In the example shown, the heating, ventilation, and / or air conditioning unit is, for example, symmetrical about the centerline Oy.

[0057] For example, refer to Figure 2 and Figure 3 The first outlet 160 can be a foot outlet, and the foot outlet may further include, for example, a front foot outlet 161 and a rear foot outlet 162, the center line of the opening of the rear foot outlet 162 being, for example, line AA. It should be understood that the embodiments of this disclosure are not limited to the specific number of the first outlet.

[0058] The second outlet 180 can be a ventilation outlet or a defogging outlet. Embodiments of this disclosure are not limited to the specific number or type of the second outlet.

[0059] The layered partition wall 150 refers to a wall-like structure used to stratify the airflow within the housing, and the partition wall may include, for example, multiple sub-partition walls for achieving airflow stratification.

[0060] Specifically, refer to Figure 3 The layered partition wall 150 includes, for example, a first partition wall 151. The first partition wall 151 has a first partition portion 1511, which separates a first space V1 and a second space V2 within the housing 110.

[0061] like Figure 3 As shown, for example, a through opening is formed inside the housing via the first partition wall to achieve engagement with a corresponding damper, and the first partition wall may include multiple partitions as needed, such as a first partition and a second partition.

[0062] It should be understood that the first space V1 and the second space V2 refer to two subspaces within the shell separated by the first partition wall. Figure 3 The first space V1 is schematically shown by a gray diagonal line from the lower left to the upper right, and the second space V2 is schematically shown by a black diagonal line from the upper left to the lower right.

[0063] The heating, ventilation and / or air conditioning device 100 further includes a first damper 170, which is disposed inside the housing 110 and is operably positioned in a first position and a second position.

[0064] The first damper is, for example, a plate-shaped damper that can rotate around its own axis between two extreme positions. The first and second positions refer, for example, to the two extreme positions of the first damper 170: a fully open position and a fully closed position. Specifically, the first position is, for example, the fully open position of the first damper, such as the position where the first damper is fully open and abuts against the first partition wall 151 (e.g.,...). Figure 3 (As shown). The second position is, for example, the fully closed position, that is, the position in which the first damper abuts against the internal structure of the housing and the opening corresponding to the first damper is completely closed.

[0065] The phrase "operably in the first position and the second position" means that the opening position of the first damper can be adjusted according to actual conditions. For example, the position of the first damper can be adjusted by controlling the rotation direction and position of the rotary motor connected to the first damper, or the position of the first damper can be adjusted in other ways so that it is in the first position or the second position as needed. It should be understood that the embodiments of this disclosure are not limited to the specific adjustment method of the opening position of the first damper.

[0066] Reference Figure 3When the first damper 170 is in the first position, the first damper 170 engages with the first partition 1511 to guide the airflow in the second space V2 out through the second outlet 180 and guide the airflow in the first space V1 out through the first outlet 160.

[0067] Figure 4 It shows according to Figure 2 The central axis Oy provides a cross-sectional view of the heating, ventilation, and / or air conditioning unit 100, wherein the first damper is in the second position (fully closed position). (Refer to...) Figure 4 When the first damper 170 is in the second position, the first damper 170 closes the first outlet 160 so that the airflow in the first space V1 and the airflow in the second space V2 both flow out from the second outlet 180.

[0068] Based on the above, in this application, while achieving good heating, ventilation, and / or air conditioning functions, a layered partition wall is provided in the heating, ventilation, and / or air conditioning device. The first partition of the first partition wall in the layered partition wall separates the first space V1 and the second space V2 within the housing. Through the cooperation of the first partition and the first damper, when the first damper is in the first position, the first damper and the first partition are engaged to guide the airflow in the second space V2 to flow out through the second outlet, and guide the airflow in the first space V1 to flow out through the first outlet. Thus, through the reasonable planning and arrangement of the structural components within the housing, the first damper is reused to participate in the separation and guidance of airflow space. This allows for the flexible cooperation between the first partition of the first partition wall and the first damper component to effectively separate two airflow spaces for different airflows, and guide the airflow in different airflow spaces to be output through different outlets. This facilitates the flexible layout of the airflow types in each outlet of the heating, ventilation, and / or air conditioning device according to actual needs, realizing multiple working modes.

[0069] Figure 5 It shows according to Figure 2 The central axis Oy provides a cross-sectional view of the heating, ventilation and / or air conditioning unit 100, wherein the first mixing damper and the second mixing damper are in the fully open position. Figure 6 It shows according to Figure 2 The central axis Oy provides a cross-sectional view of the heating, ventilation and / or air conditioning unit 100, wherein the first mixing damper and the second mixing damper are in the fully closed position.

[0070] In some embodiments, refer to Figure 5 The heating, ventilation and / or air conditioning device 100 further includes a first airflow processing unit 130, a first mixing damper 310 and / or a second mixing damper 320.

[0071] Reference Figure 5 The first airflow processing unit 130 is disposed within the housing 110 and is located upstream of the first partition wall 151. It should be understood that the upstream and downstream terms in this application are determined along the flow direction of the intake airflow.

[0072] It should be understood that, depending on actual needs, the first airflow processing unit 130 may be a heater, such as a PTC heater.

[0073] The first mixing damper 310 refers to a damper component used to regulate the temperature of the airflow entering the first space V1; the second mixing damper 320 refers to a damper component used to regulate the temperature of the airflow entering the second space V2. Figure 5 As shown, the first mixing damper and the second mixing damper can be arranged downstream of the first airflow processing unit 130 along the flow direction of the intake airflow, and upstream of the corresponding first space V1 and second space V2, so as to adjust the airflow temperature in the first space and the second space by controlling the proportion of airflow passing through and bypassing the first airflow processing unit 130.

[0074] It should be understood that the first and second mixing dampers can be damper components of the same type and size, or different types or sizes of damper components can be selected according to actual needs. The embodiments of this disclosure are not limited to the type and size relationship between the first and second mixing dampers.

[0075] For example, both the first mixing damper and the second mixing damper can be as follows: Figure 5 The sliding damper shown has its sliding damper flaps operable to slide in two opposite directions around its sliding central axis to control the opening position of the sliding damper. Furthermore, each of the first and second mixing dampers has, for example, two extreme positions: a fully open position and a fully closed position, and both the first and second mixing dampers are movable between these fully open and fully closed positions.

[0076] Comprehensive reference Figure 3 and Figure 5 The first partition wall 151 also has, for example, a second partition 1512. The second partition 1512 divides a third space V3 and a fourth space V4 within the housing 110. A portion of the airflow from the first airflow processing unit 130 enters the third space V3, and another portion enters the fourth space V4. Figure 5 The third space V3 is schematically shown filled with black particles, and the fourth space V4 is schematically shown filled with vertical lines.

[0077] It should be understood that the third space and the fourth space are only intended to show two different airflow spaces divided by the second partition of the first partition wall, and are not intended to limit them.

[0078] When the first mixing damper 310 is in the fully open position, it separates the third space V3 from the first space V1. When the second mixing damper 320 is in the fully open position, it separates the fourth space V4 from the second space V2.

[0079] Specifically, the fully open position of the first mixing damper 310 refers, for example, to the position where the first mixing damper is engaged with the second partition to achieve the separation of the first space and the third space. For instance, it refers to the position where the first mixing damper 310 slides to its limit position along the first direction and engages with the second partition 1512 (e.g., ...). Figure 5 (As shown). For example, refer to Figure 5 When the first mixing damper 310 is in the fully open position, one end of the first mixing damper 310 is engaged with the second partition 1512, and the other end is engaged with the inner wall of the housing. At this time, the second partition 1512, the first mixing damper 310 and the inner wall of the housing cooperate to separate the third space V3 from the first space V1.

[0080] For example, in this case, such as Figure 5 As shown, for the stratified airflow corresponding to the first mixing damper, the airflow flowing through the first airflow processing unit 130 in the stratified airflow will be blocked by the first mixing damper 310 and will not be able to enter the first space V1. That is, for the stratified airflow corresponding to the first mixing damper, only a part of the airflow that does not flow through the first airflow processing unit 130 can enter the first space (that is, it can be output through the corresponding outlet later).

[0081] The fully closed position of the first mixing damper 310 refers, for example, to the position where the first mixing damper 310 slides to its limit in a second direction that is substantially opposite to the first direction (e.g., Figure 6 As shown), the first mixing damper is positioned to engage with the inner wall of the housing to separate the first space and the fifth space described below. In this case, as... Figure 6 As shown, for the stratified airflow corresponding to the first mixing damper, the airflow that has not flowed through the first airflow processing unit 130 will not be able to enter the first space V1 due to the obstruction of the first mixing damper 310. That is, for the stratified airflow corresponding to the first mixing damper, only a part of the airflow that has flowed through the first airflow processing unit 130 can enter the first space (that is, it can be output through the corresponding outlet later).

[0082] The fully open position of the second mixing damper 320 refers to the position where the second mixing damper 320 slides to its limit position along a third direction and engages with the second partition 1512 (e.g., Figure 5 (As shown). For example, refer to Figure 5 When the second mixing damper 320 is in the fully open position, one end of the second mixing damper 320 is engaged with the second partition 1512, and the other end is engaged with the inner wall of the housing. At this time, the second partition 1512, the second mixing damper 320 and the inner wall of the housing cooperate to separate the fourth space V4 from the second space V2.

[0083] For example, in this case, such as Figure 5 As shown, for the stratified airflow corresponding to the second mixing damper, the airflow flowing through the second airflow processing unit 130 will be blocked by the second mixing damper 320 and will not be able to enter the second space V2. That is, for the stratified airflow corresponding to the second mixing damper, only a portion of the airflow that does not flow through the first airflow processing unit 130 can enter the second space (that is, it can be output through the corresponding outlet later).

[0084] The fully closed position of the second mixing damper 310 refers to the position where the second mixing damper 320 slides to its limit in a fourth direction that is substantially opposite to the third direction (e.g., Figure 6 (As shown). At this time, the second mixing damper is in a position that engages with the inner wall of the housing to separate the second space and the sixth space described below. In this case, as Figure 6 As shown, for the stratified airflow corresponding to the second mixing damper, the airflow that has not flowed through the first airflow processing unit 130 will not be able to enter the second space V2 due to the obstruction of the second mixing damper 320. That is, for the stratified airflow corresponding to the second mixing damper, only a part of the airflow that has flowed through the first airflow processing unit 130 can enter the second space (that is, it can be output through the corresponding outlet later).

[0085] For example, the first mixing damper can be set in the flow path of the upper airflow in the stratified airflow to achieve temperature regulation of the upper airflow in the stratified airflow, and the second mixing damper can be set in the flow path of the lower airflow in the stratified airflow to achieve temperature regulation of the lower airflow.

[0086] It should be understood that although the above description focuses on the two extreme positions of the first mixing damper and the two extreme positions of the second mixing damper, the first mixing damper and the second mixing damper can be positioned in any intermediate position between the fully open and fully closed positions as needed (e.g., Figure 3 As shown, the airflow pattern in this intermediate position will be explained in more detail below in conjunction with the functional modes of heating, ventilation, and / or air conditioning.

[0087] Based on the above, in this application, by configuring the housing to include a first mixing damper, a second mixing damper, and a first airflow processing unit (e.g., a heater), the temperature of the airflow entering the first space can be adjusted according to actual needs by adjusting the opening position of the first mixing damper; the temperature of the airflow entering the second space can be adjusted by adjusting the opening position of the second mixing damper, thus achieving independent adjustment of the temperatures of different airflows after stratification. Furthermore, a second partition separates a third space and a fourth space within the housing. When the first mixing damper is in the fully closed position, the third space is separated from the first space; when the second mixing damper is in the fully closed position, the fourth space is separated from the second space. This allows the first and second mixing dampers to be reused as spacers between adjacent spaces, thereby optimizing the structural layout within the housing.

[0088] Reference Figure 6 In some embodiments, the layered partition wall 150 further has a second partition wall 152.

[0089] The second partition wall 152 is located upstream of the first airflow processing unit 130, and the second partition wall 152 separates the fifth space V5 and the sixth space V6 within the housing 110.

[0090] For example, refer to Figure 6 The second partition wall originates from the lower surface of the first airflow treatment unit 130 (e.g., at the midpoint of the lower surface) and extends, for example, to a corresponding inner wall of the housing or engages with other components within the housing, for example in... Figure 6 In this process, it engages, for example, with the inner surface of a second airflow processing unit (e.g., an evaporator) to separate the fifth and sixth spaces.

[0091] Furthermore, part of the airflow passing through the first airflow processing unit 130 comes from the fifth space V5, and the other part comes from the sixth space V6.

[0092] Furthermore, when the first mixing damper 310 is in the fully closed position, it separates the fifth space V5 from the first space V1; when the second mixing damper 320 is in the fully closed position, it separates the sixth space V6 from the second space V2.

[0093] For example, refer to Figure 6 When the first mixing damper is in the fully closed position as described above, both ends of the first mixing damper engage with the corresponding internal walls of the housing. At this time, the corresponding internal walls of the housing, the first mixing damper, and the second partition wall cooperate to separate the fifth space V5 from the first space V1. Further referencing... Figure 6 When the second mixing damper is in the fully closed position as described above, both ends of the second mixing damper are also engaged with the corresponding internal walls inside the housing. At this time, the corresponding internal walls of the housing, the second mixing damper, and the second partition wall cooperate to separate the sixth space V6 from the second space V2.

[0094] Based on the above, in this application, by setting the layered partition wall to further include a second partition wall, a fifth space and a sixth space are further divided upstream of the first airflow processing unit via the second partition wall. This allows for the setting of different airflow spaces corresponding to different layered airflows upstream of the first airflow processing unit, thereby providing good layered airflow spaces in both the upper and lower flow paths of the first airflow processing unit. Furthermore, by setting the first mixing damper to be in the fully closed position to separate the fifth space from the first space, and the second mixing damper to be in the fully closed position to separate the sixth space from the second space, the first mixing damper and the second mixing damper can be reused to the maximum extent to achieve the separation and connection of each space according to actual needs. This facilitates the flexible selection and setting of airflow paths and the guidance of airflow direction, and enables the device to achieve multiple working modes.

[0095] In some embodiments, the heating, ventilation and / or air conditioning device 100 further includes a second airflow processing unit 120.

[0096] For example, the second airflow processing unit may be a heat exchanger. Specifically, it may be an evaporator in cooling mode and a condenser in heat pump mode.

[0097] Reference Figure 6 The second airflow processing unit 120 is disposed within the housing 110 and is located upstream of the second partition wall 152.

[0098] For example, refer to Figure 6 The second airflow processing unit can be located, for example, near the inlet of the heating, ventilation and / or air conditioning unit, and the airflow entering the housing will first pass through the second airflow processing unit.

[0099] For example, one end of the second partition wall is joined to the lower surface of the first airflow treatment unit, and the other end of the second partition wall is joined to the inner surface of the second airflow treatment unit (facing the inside of the housing).

[0100] Among them, part of the airflow through the second airflow processing unit 120 enters the fifth space V5, and the other part enters the sixth space V6.

[0101] Based on the above, by providing a second airflow processing unit 120 to the heating, ventilation and / or air conditioning device 100, and further configuring the second airflow processing unit to be located upstream of the second partition wall, the stratified airflow entering the heating, ventilation and / or air conditioning device 100 can first be processed by the second airflow processing unit (e.g., processed by the evaporator), and then enter the fifth space V5 and the sixth space V6 respectively, and subsequently, according to actual needs, be further processed by the first airflow processing unit (e.g., heated by the heater), thereby facilitating multi-level processing of the intake airflow according to actual needs, so as to achieve good heating, ventilation and / or air conditioning effects.

[0102] In some embodiments, the first outlet 160 is a foot outlet. And in this case, the airflow output through the first outlet is, for example, recirculated air.

[0103] In this application, by setting the first outlet as a foot-blowing outlet, the first intake airflow (e.g., the upper intake airflow) among the multiple intake airflows entering in layers can pass through the airflow path composed of the second airflow processing unit, the fifth space and / or the third space, and the first space, and finally be completely output through the foot-blowing outlet when it is open, via the layered partition wall and the corresponding airflow space. In particular, when the first airflow is internally recirculated air, the foot-blowing operation can be performed simultaneously with ventilation and defogging using fresh air via the layered partition wall and internally recirculated air.

[0104] In some embodiments, the second outlet 180 includes at least one of a ventilation outlet and a defogging outlet. In this case, the airflow output through the second outlet is, for example, fresh air.

[0105] In this application, by setting the second outlet as at least one of a ventilation outlet and a defogging outlet, when the input stratified airflow is internal recirculated air and fresh air, the internal recirculated air can be used as the first intake airflow (e.g., upper intake airflow) through the airflow path formed by the second airflow processing unit, the fifth space and / or the third space, and the first space, and is output from the foot outlet under the guidance of the first airflow through the cooperation of the first damper and the stratified partition wall. At the same time, fresh air can also be used as the second intake airflow (e.g., lower intake airflow) through the airflow path formed by the second processing unit, the sixth space and / or the fourth space, and the second space, and is output from the second outlet under the guidance of the first airflow through the first damper, thereby achieving ventilation and / or defogging functions.

[0106] In some embodiments, refer to Figure 6 The second airflow processing unit 120 and the first airflow processing unit 130 are arranged substantially orthogonally. For example, the first airflow processing unit 130 is arranged substantially horizontally relative to the vehicle in the installed state, and the second airflow processing unit 120 is arranged substantially vertically relative to the vehicle in the installed state.

[0107] Based on the above, in this application, by arranging the second airflow processing unit 120 and the first airflow processing unit 130 in a substantially orthogonal manner, compared to the currently commonly adopted parallel layout of the first and second airflow processing units (e.g., the first and second processing units are both placed vertically, or both are horizontal, or are tilted at the same angle), this application, by adopting the orthogonal arrangement of the first and second airflow processing units, can achieve an ultra-thin design, especially reducing the three-dimensional volume of the heating, ventilation, and / or air conditioning device in the Z-direction (vertical) direction; on the other hand, by setting the first and second airflow processing units in a vertical layout, the internal space of the shell can be better improved under this layout, which is conducive to further setting up layered partition walls and forming airflow spaces corresponding to different layered airflows, that is, it is conducive to better optimizing the internal structure of the shell and achieving better layered airflow flow and guidance based on this vertical layout.

[0108] In some embodiments, the first outlet 160 is located above the second airflow processing unit 120.

[0109] By positioning the first outlet 160 above the second airflow handling unit 120, the structural layout of the heating, ventilation and / or air conditioning device can be optimized, and it is beneficial to better output airflow through the first outlet (e.g., foot outlet) after the heating, ventilation and / or air conditioning device is installed on the dashboard of the motor vehicle.

[0110] In some embodiments, refer to Figure 2 The heating, ventilation and / or air conditioning unit 100 further includes a central partition wall 141, which divides the housing into a left half 112 and a right half 113.

[0111] The left and right halves, for example, have a structure that is symmetrical along the plane of the central partition wall, and both have, for example, the aforementioned combination. Figures 1-11 The structural components and functional modes are shown.

[0112] For example, Figure 2 The image shows the right half of the blowhole opening 160, which includes a front blowhole outlet and a rear blowhole outlet, and is combined with... Figures 7 to 11The corresponding cross-sectional view of the right half of the housing shown includes, for example, a front ventilation outlet, a rear ventilation outlet, and a demisting outlet. Correspondingly, the left half of the housing has, for example, a front ventilation outlet, a rear ventilation outlet, a demisting outlet, a front foot outlet, and a rear foot outlet, and correspondingly has a layered partition wall, a first airflow processing unit, and a second airflow processing unit.

[0113] For example, after the heating, ventilation, and / or air conditioning unit 100 is installed in a motor vehicle, the left half 113 is configured, for example, to provide corresponding heating, ventilation, and / or air conditioning functions to the right side (passenger side) of the motor vehicle, and can be flexibly switched between foot-blowing ventilation dual mode, foot-blowing defogging dual mode, defogging mode, foot-blowing mode, and ventilation mode. Similarly, after the heating, ventilation, and / or air conditioning unit 100 is installed in a motor vehicle, the right half 114 is configured, for example, to provide corresponding heating, ventilation, and / or air conditioning functions to the left side (driver side) of the motor vehicle, and can be flexibly switched between foot-blowing ventilation dual mode, foot-blowing defogging dual mode, defogging mode, foot-blowing mode, and ventilation mode.

[0114] It should be understood that the above only provides an exemplary working mode for the left and right halves. Depending on actual needs, the left half 112 can also be configured to provide corresponding heating, ventilation and / or air conditioning functions to the left side (driver's side) of the motor vehicle, and the right half 113 can provide corresponding heating, ventilation and / or air conditioning functions to the right side (passenger side) of the motor vehicle.

[0115] Based on the above, in this application, by setting a central partition wall, the housing is divided into a left half and a right half. This allows the heating, ventilation and / or air conditioning device 100 to be further divided into left and right zones by the central partition wall, based on the previously described airflow stratification and independent temperature control of the stratified airflow. The left half and the right half can be controlled independently, so that the left half and the right half can be independently configured in foot ventilation dual mode, foot defogging dual mode, defogging mode, foot mode, and ventilation mode. This enables different heating, ventilation and / or air conditioning functions to be provided to the right side (passenger side) and the left side (driver side) of the motor vehicle, and realizes the dual-layer dual-zone design of the heating, ventilation and / or air conditioning device.

[0116] The airflow path and corresponding operating mode of the heating, ventilation, and / or air conditioning device 100 will be described in more detail below with reference to specific embodiments. The heating, ventilation, and / or air conditioning device 100 can, for example, be a double-layer, double-zone heating, ventilation, and / or air conditioning device, meaning that the device 100 can introduce intake airflow (which can be of the same type or different types) into the upper and lower airflow inlets respectively, thereby achieving relatively independent airflow paths and channels for the upper and lower airflows. Furthermore, the heating, ventilation, and / or air conditioning device 100 can, for example, be symmetrical about a central axis, specifically, it is divided into a left half and a right half via the central axis, and the left half and the right half have the same structure.

[0117] For example, refer to Figure 3 The heating, ventilation and / or air conditioning unit 100 has a housing 110, and the housing has, for example, the following features: Figure 1-3 The internal structure of the housing is shown. Specifically, the housing defines an inlet 111, a first outlet (here, a foot blowing outlet) 160, and a second outlet 180 (which, for example, may include a demisting outlet 181 and / or a ventilation outlet 182, depending on actual needs).

[0118] And refer to Figure 1 and Figure 3 The first outlet (foot outlet) includes, for example more specifically, a front foot outlet 161 and a rear foot outlet 162; the ventilation outlet 182 includes, for example more specifically, a front ventilation outlet 1821 and a rear ventilation outlet 1822.

[0119] Furthermore, the housing may also include, for example, the second airflow processing unit 130, the layered partition wall 150, the first airflow processing unit 120, the first damper 170, the first mixing damper 310, and the second mixing damper 320, as described above. The second airflow processing unit 130 is, for example, an evaporator, located near the inlet 111 of the housing. The first airflow processing unit 120 is, for example, a heater.

[0120] The layered partition wall 150 includes, for example, a first partition wall 151 and a second partition wall 152 as described above, and the first partition wall 151 has, for example, a first partition portion 1511 and a second partition portion 1522. The first partition portion 1511 separates a first space V1 and a second space V2, and the second partition portion 1512 separates a third space V3 and a fourth space V4. The second partition wall 152 separates a fifth space V5 and a sixth space V6. Figure 6As shown, the upstream end of the second partition wall 152 is connected to the inner side of the second airflow processing unit 130, and the downstream end of the second partition wall 152 is connected to the lower surface of the first airflow processing unit 120.

[0121] The first damper is a damper component configured for a first opening (foot opening), and is configured to control the opening degree of the first opening. As detailed above, when the first damper 170 is in the first position, the first damper 170 engages with the first partition 1511 to guide the airflow in the second space V2 out through the second outlet 180 and to guide the airflow in the first space V1 out through the first outlet 160; when the first damper 170 is in the second position, the first damper 170 closes the first outlet 160 so that the airflow in the first space V1 and the airflow in the second space V2 both flow out through the second outlet 180.

[0122] The first mixing damper 310 is configured to adjust the ratio of airflow passing through the first airflow processing unit to airflow bypassing the first airflow processing unit, thereby adjusting the temperature of the airflow entering the first space V1. When the first mixing damper 310 is in the fully open position, it separates the third space V3 from the first space V1; when the first mixing damper 310 is in the fully closed position, it separates the fifth space V5 from the first space V1.

[0123] The second mixing damper 320 is configured to adjust the ratio of airflow passing through the first airflow processing unit to airflow bypassing the first airflow processing unit, thereby adjusting the temperature of the airflow entering the second space V2. When the second mixing damper 320 is in the fully open position, it separates the fourth space V4 from the second space V2; when the second mixing damper 320 is in the fully closed position, it separates the sixth space V6 from the second space V2.

[0124] And refer to Figure 4 The housing also includes a defogger 191, a front ventilation damper 1921, and a rear ventilation damper 1922. The defogger 191 is configured to adjust the opening of the defogger outlet 181. The front ventilation damper 1921 is configured to adjust the opening of the front ventilation outlet 1821, and the rear ventilation damper 1922 is configured to adjust the opening of the rear ventilation outlet 1822. (Refer to...) Figure 4 The defogger 191 and the front ventilation 1921 are, for example, sliding dampers, and the rear ventilation damper is, for example, a butterfly damper.

[0125] The different operating modes of the heating, ventilation and / or air conditioning unit 100 will be described in detail below.

[0126] Foot blowing and ventilation dual modes

[0127] Figure 7 It shows according to Figure 2 The AA line in the diagram provides a cross-sectional view of the heating, ventilation and / or air conditioning unit 100, wherein the heating, ventilation and / or air conditioning unit 100 is in a foot-ventilation dual mode.

[0128] Reference Figure 7 When the heating, ventilation, and / or air conditioning unit 100 is in foot-blowing ventilation dual mode, the first damper 170 is configured in the first position to fully open the foot-blowing opening 160 and engage with the first partition to guide airflow. The demisting damper 191 is in the fully closed position to completely close the demisting outlet, while the front ventilation damper 1921 and the rear ventilation damper 1922 are open. The specific opening positions can be adjusted according to actual needs to allow the front and rear ventilation outlets to open at the desired degree.

[0129] At this point, for example, the opening degrees of the first mixing damper and the second mixing damper can be further adjusted to control the proportion of stratified airflow passing through and bypassing the first airflow processing unit 120 (heater). Figure 7 In the example shown, the first mixing damper 310 and the second mixing damper 320 are both in the middle position, for example.

[0130] At this time, the upper layer of the casing inlet is for example, where internal recirculated air is introduced, and the lower layer of the casing inlet is for example, where fresh air is introduced. The airflow within the casing is specifically as follows: For the upper airflow, the upper intake airflow (here, the internal recirculated air intake airflow) F1i enters from the upper part of the inlet, first passing through the second airflow processing unit 130 (evaporator). Afterward, the upper intake airflow F1i is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120, enters the fifth space V5, and directly enters the first space V1 from the left side of the first mixing damper 310 (e.g., ...). Figure 7 (The airflow direction is shown by dashed lines). The second airflow branch of the upper intake airflow F1i will pass through the first airflow processing unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space V3 through the first airflow processing unit 120, and enter the first space V1 via the right side of the first mixing damper 310 (as shown in the image). Figure 7(The airflow direction is shown in the dotted line). The second airflow branch passing through the first airflow processing unit 120 will be heated by the heater to have a higher temperature than the first airflow branch. Subsequently, in the first space V1, the two airflow branches will mix and form an upper output airflow (here, an internal recirculation air output airflow) F1o. At this time, the first damper 170 in the first position will engage with the first partition and guide the upper output airflow F1o in the first space V1 to flow out through the first outlet 160. Here, the upper output airflow F1o is output, for example, through the rear foot outlet 161 and the front foot outlet 162.

[0131] For the lower airflow, when fresh air is introduced, the lower air intake airflow (here, the fresh air intake airflow) F2i enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower air intake airflow F2i is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120 and enters the sixth space V6, and directly enters the second space V2 from the right side of the second mixing damper 320 from the sixth space V6. Figure 7 (The airflow direction is shown by dashed lines). The second airflow branch of the lower intake airflow F2i will pass through the first airflow processing unit (heater) 120, specifically, it will enter the sixth space V6, then enter the fourth space V4 through the first airflow processing unit 120, and finally enter the second space V2 from the left side of the second mixing damper 320 (as shown in the image). Figure 7 (The airflow direction is shown by a dotted line in the diagram). The second airflow branch passing through the first airflow processing unit 120 will be heated by the heater to have a higher temperature than the first airflow branch. Subsequently, in the second space V2, the two airflow branches will mix and form a lower output airflow F2o. At this time, the first damper 170 in the first position will engage with the first partition and guide the lower output airflow F2o in the second space V2 to flow out through the second outlet. Here, the lower output airflow (here, the fresh air output airflow) F2o is output, for example, through the front ventilation outlet 1821 and the rear ventilation outlet 1822.

[0132] Based on this, it is possible to achieve stratified entry of recirculated air and fresh air through the layered partition wall, and corresponding airflow space is set for each layer of airflow. Furthermore, by reusing the first damper and connecting it to the first partition, the airflow space is well divided, and the airflow in the first and second spaces is effectively guided. This allows for ventilation through the ventilation outlet while recirculated air is used to warm the feet through the foot-blowing outlet, thus achieving both ventilation and foot warmth. In addition, the recirculated air output airflow F1o and the fresh air output airflow F2o from the foot-blowing outlet and the ventilation outlet respectively can be independently temperature-controlled through the first and second mixing dampers, allowing for flexible adjustment of the output airflow temperature from the foot-blowing outlet and the ventilation outlet. Compared to current heating, ventilation and / or air conditioning devices where only the front vent can discharge fresh air, while the rear vent, front foot outlet and rear foot outlet discharge recirculated air, the heating, ventilation and / or air conditioning system proposed in this application can achieve the function of discharging fresh air from both the front and rear vents, and discharging recirculated air from both the front foot outlet and rear foot outlet.

[0133] Foot blowing and defogging dual modes

[0134] Figure 8 It shows according to Figure 2 The AA line in the diagram provides a cross-sectional view of the heating, ventilation and / or air conditioning unit 100, wherein the heating, ventilation and / or air conditioning unit 100 is in a foot blowing and defogging dual mode.

[0135] Reference Figure 8 When the heating, ventilation, and / or air conditioning unit 100 is in the foot-blowing and demisting dual-mode, the first damper 170 is configured in the first position to fully open the foot-blowing opening 160 and engage with the first partition to guide airflow. The demisting damper 191 will be in the open position, and the specific opening degree can be adjusted according to actual needs to flexibly control the opening degree of the demisting outlet (e.g., at...). Figure 8 The defogger is in the fully open position, while the front ventilation damper 1921 and the rear ventilation damper 1922 are in the fully closed position to completely close the front ventilation outlet and the rear ventilation outlet.

[0136] At this point, for example, the opening degrees of the first mixing damper 310 and the second mixing damper 320 can be further adjusted to control the proportion of airflow passing through and bypassing the first airflow processing unit 120 (heater). Figure 8 In the example shown, the first mixing damper 310 and the second mixing damper 320 are both in the middle position, for example.

[0137] At this time, for example, internal recirculated air is introduced into the upper layer of the casing inlet, and for example, fresh air is introduced into the lower layer of the casing inlet. The airflow within the casing is specifically as follows: For the upper airflow, the upper intake airflow (here, the internal recirculated air intake airflow) F1i enters from the upper part of the inlet, first passing through the second airflow processing unit 130 (evaporator). Then, the upper intake airflow F1i is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120, enters the fifth space V5, and directly enters the first space V1 (e.g., from the left side of the first mixing damper 310) from the left side of the first mixing damper 310. Figure 8 (The airflow direction is shown by dashed lines). The second airflow branch of the upper intake airflow F1i will pass through the first airflow processing unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space V3 through the first airflow processing unit 120, and enter the first space V1 via the right side of the first mixing damper 310 (as shown in the image). Figure 8 (The airflow direction is shown in the dotted line). The second airflow branch passing through the first airflow processing unit 120 will be heated by the heater to have a higher temperature than the first airflow branch. Subsequently, in the first space V1, the two airflow branches will mix and form an upper output airflow (here, an internal recirculation airflow) F1o. At this time, the first damper 170 in the first position will engage with the first partition and guide the upper output airflow F1o in the first space V1 to flow out through the first outlet 160. Here, the upper output airflow (internal recirculation airflow) F1o is output, for example, through the rear foot outlet 162 and the front foot outlet 161.

[0138] For the lower airflow (fresh air), the lower intake airflow (in this case, fresh air intake airflow) F2i enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower intake airflow F2i is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120 and enters the sixth space V6, and directly enters the second space V2 from the right side of the second mixing damper 320 from the sixth space V6. Figure 8 (The airflow direction is shown by dashed lines). The second airflow branch of the lower intake airflow F2i will pass through the first airflow processing unit (heater) 120, specifically, it will enter the sixth space V6, then enter the fourth space V4 through the first airflow processing unit 120, and finally enter the second space V2 from the left side of the second mixing damper 320 (as shown in the image). Figure 8(The airflow direction is shown by a dotted line in the diagram). The second airflow branch passing through the first airflow processing unit 120 will be heated by the heater to have a higher temperature than the first airflow branch. Subsequently, in the second space V2, the two airflow branches will mix and form a lower output airflow (fresh air output airflow) F2o. At this time, the first damper 170 in the first position will engage with the first partition and guide the lower output airflow F2o in the second space V2 to flow out through the second outlet, which is, for example, through the demisting outlet 181.

[0139] Based on this, the stratified partition wall enables the stratified entry of recirculated air and fresh air, and provides corresponding airflow spaces for each layer. By reusing the first damper and connecting it to the first partition, the airflow spaces are well-defined, allowing for effective guidance of airflow within the first and second spaces. This allows for both defogging via fresh air through the defogger outlet and foot warming via recirculated air through the foot warmer outlet, achieving both defogging and foot insulation. Furthermore, the recirculated air output F1o and fresh air output F2o from the foot warmer outlet and defogger outlet, respectively, can be independently temperature-controlled via the first and second mixing dampers, enabling flexible adjustment of the output airflow temperature from the foot warmer outlet and defogger outlet.

[0140] Defogging mode

[0141] Figure 9 It shows according to Figure 2 The AA line in the diagram provides a cross-sectional view of a heating, ventilation, and / or air conditioning unit 100, wherein the heating, ventilation, and / or air conditioning unit 100 is in defogging mode.

[0142] Reference Figure 9 When the heating, ventilation, and / or air conditioning unit 100 is in demisting mode, the first damper 170 is configured in the second position to completely close the foot opening 160. The demisting damper 191 will be in the open position, and the specific opening degree can be adjusted according to actual needs to flexibly control the opening degree of the demisting outlet, for example, in... Figure 9 The defogger 191 is in the fully open position to fully open the defogger outlet 181. The front ventilation damper 1921 and the rear ventilation damper 1922 are in the fully closed position to completely close the front ventilation outlet and the rear ventilation outlet.

[0143] At this point, for example, the opening degrees of the first mixing damper 310 and the second mixing damper 320 can be further adjusted to control the proportion of stratified airflow flowing through and bypassing the first airflow processing unit 120 (heater). Figure 9In the example shown, the first mixing damper 310 and the second mixing damper 320 are both in the fully closed position, so that each layer of airflow passes completely through the first airflow processing unit 120.

[0144] At this time, fresh air is introduced into both the upper and lower layers of the casing inlet, and the airflow within the casing is as follows: For the upper airflow, the upper intake airflow F1i (here, the fresh air intake airflow) enters from the upper part of the inlet, first passing through the second airflow processing unit 130 (evaporator), and then the upper intake airflow F1i will pass entirely through the first airflow processing unit (heater) 120. Specifically, it will enter the fifth space V5, and then through the first airflow processing unit 120 into the third space V3, and then through the right side of the first mixing damper 310 into the first space V1 (e.g., Figure 9 (The direction of airflow is indicated by dotted lines).

[0145] For the lower airflow, the lower intake airflow (here, fresh air intake airflow) F2i enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower intake airflow F2i will all pass through the first airflow processing unit (heater) 120. Specifically, it will enter the sixth space V6, then enter the fourth space V4 through the first airflow processing unit 120, and finally enter the second space V2 from the left side of the second mixing damper 320 (e.g., Figure 9 (The direction of airflow is indicated by dotted lines in the diagram).

[0146] At this time, the first damper 170 in the second position completely closes the foot outlet, so that the upper air intake airflow F1i in the first space V1 and the lower air intake airflow F2i in the second space V2 together form the output airflow Fo, and the output airflow Fo is output through the demisting outlet 181.

[0147] Based on this, in defogging mode, fresh air can be introduced in layers via a stratified partition wall, and corresponding airflow spaces are set for each layer. Furthermore, by positioning the first damper in the second position, the airflow spaces are well-defined, ensuring that airflow in both the first and second spaces can exit through the defogging outlet. In addition, the upper and lower airflows can be independently temperature-controlled via the designated first and second mixing dampers, allowing for flexible temperature control of each layer in the stratified airflow.

[0148] Foot blowing mode

[0149] Figure 10 It shows according to Figure 2The AA line in the diagram provides a cross-sectional view of the heating, ventilation and / or air conditioning unit 100, wherein the heating, ventilation and / or air conditioning unit 100 is in foot-blowing mode.

[0150] When the heating, ventilation, and / or air conditioning unit 100 is in foot-blowing mode, the first damper 170 is configured in a first position to fully open the foot-blowing opening 160 and engage with the first partition to guide airflow. The demisting damper 191 will be operable in the open position, and the specific opening position can be adjusted according to actual needs to flexibly control the opening of the demisting outlet, for example, in... Figure 10 The defogger 191 is in an intermediate position between the fully open and fully closed positions, and close to the fully closed position, so as to slightly open the defogger outlet 181 to prevent fogging of the vehicle windows. The front ventilation damper 1921 and the rear ventilation damper 1922 are in the fully closed position to completely close the front ventilation outlet 1821 and the rear ventilation outlet 1822.

[0151] At this point, for example, the opening degrees of the first mixing damper 310 and the second mixing damper 320 can be further adjusted to control the proportion of stratified airflow flowing through and bypassing the first airflow processing unit 120 (heater). Figure 10 In the example shown, the first mixing damper 310 and the second mixing damper 320 are both in the fully closed position, so that each layer of airflow passes completely through the first airflow processing unit 120.

[0152] At this time, the upper layer of the casing inlet is supplied with internal recirculated air, and the lower layer of the casing inlet is supplied with fresh air. The airflow within the casing is as follows: For the upper airflow, the upper intake airflow F1i (here, internal recirculated intake airflow) enters from the upper part of the inlet, first passing through the second airflow processing unit 130 (evaporator). Then, the upper intake airflow F1i passes entirely through the first airflow processing unit (heater) 120. Specifically, it enters the fifth space V5, and subsequently passes through the first airflow processing unit 120 into the third space V3, and then enters the first space V1 via the right side of the first mixing damper 310 (e.g., ...). Figure 10 (The airflow direction is shown in the dotted line). Subsequently, the airflow entering the first space will be used as the upper output airflow F1o, and the first damper 170 in the first position will engage with the first partition and guide the upper output airflow F1o in the first space V1 to flow out through the first outlet 160. Here, the upper output airflow (internal recirculated air output airflow) F1o is output through, for example, the rear foot outlet 162 and the front foot outlet 161.

[0153] For the lower airflow, the lower intake airflow (here, fresh air intake airflow) F2i enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower intake airflow F2i will all pass through the first airflow processing unit (heater) 120. Specifically, it will enter the sixth space V6, then enter the fourth space V4 through the first airflow processing unit 120, and finally enter the second space V2 from the left side of the second mixing damper 320 (e.g., Figure 10 (The airflow direction is shown by the dotted line in the diagram). Subsequently, the airflow entering the second space V2 will be used as the lower output airflow F2o, and the first damper 170 in the first position will engage with the first partition and guide the lower output airflow F2o in the second space V2 to flow out through the first outlet 160. Here, the lower output airflow (fresh air output airflow) F2o is output, for example, through the defogging outlet 181.

[0154] Based on this, in foot-blowing mode, fresh air and recirculated air can be introduced in layers via a stratified partition wall, and corresponding airflow spaces are set for each layer. Furthermore, by setting the first damper in the first position, the airflow spaces are well-defined, and the airflow in the first and second spaces can be guided, so that the recirculated airflow in the first space exits from the foot-blowing outlet, and the fresh airflow in the second space exits from the demisting outlet. In addition, the upper and lower airflows can be independently temperature-controlled via the first and second mixing dampers, respectively, allowing for flexible temperature control of each layer in the stratified airflow. This also ensures that the airflow temperatures at the foot-blowing outlet and the demisting outlet can be independently controlled in this foot-blowing mode.

[0155] Ventilation mode

[0156] Figure 11 It shows according to Figure 2 The AA line in the diagram provides a cross-sectional view of the heating, ventilation and / or air conditioning unit 100, wherein the heating, ventilation and / or air conditioning unit 100 is in ventilation mode.

[0157] When the heating, ventilation, and / or air conditioning unit 100 is in ventilation mode, the first damper 170 is configured in the second position to completely close the foot opening 160. The defrost damper 191 is in the fully closed position to completely close the defrost outlet 181. The front ventilation damper 1921 and the rear ventilation damper 1922 are in the fully open position to fully open the front ventilation outlet 1821 and the rear ventilation outlet 1822.

[0158] At this point, for example, the opening degrees of the first mixing damper 310 and the second mixing damper 320 can be further adjusted to control the proportion of stratified airflow flowing through and bypassing the first airflow processing unit 120 (heater). Figure 11 In the example shown, the first mixing damper 310 and the second mixing damper 320 are both in the fully open position, so that each layer of airflow completely bypasses the first airflow processing unit 120.

[0159] At this time, fresh air is introduced into both the upper and lower layers of the casing inlet, and the airflow within the casing is as follows: For the upper airflow, the upper intake airflow F1i (here, the fresh air intake airflow) enters from the upper part of the inlet, first passing through the second airflow processing unit 130 (evaporator). Afterward, the upper intake airflow F1i completely bypasses the first airflow processing unit (heater) 120. Specifically, it enters the fifth space V5 and directly enters the first space V1 (e.g., from the left side of the first mixing damper 310). Figure 11 (The direction of airflow is indicated by the dashed line).

[0160] For the lower airflow, the lower intake airflow (here, the fresh air intake airflow) F2i enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower intake airflow F2i completely bypasses the first airflow processing unit (heater) 120. Specifically, it enters the sixth space V6, and then directly enters the second space V2 from the right side of the second mixing damper 320 (e.g., ...). Figure 11 (The direction of airflow is indicated by dashed lines in the image).

[0161] At this time, the first damper 170 in the second position completely closes the foot outlet, so that the upper air intake airflow F1i in the first space V1 and the lower air intake airflow F2i in the second space V2 together form the output airflow Fo, and the output airflow Fo is output through the front ventilation outlet 1821 and the rear ventilation outlet 1822.

[0162] Based on this, in ventilation mode, fresh air can be introduced in layers through the stratified partition walls, and corresponding airflow spaces are set for each layer. Furthermore, by setting the first damper in the second position, the airflow spaces are well divided, ensuring that airflow in both the first and second spaces can be output from the ventilation outlets. In addition, the upper and lower airflows can be independently temperature-controlled via the first and second mixing dampers, respectively, allowing for flexible temperature control of each layer in the stratified airflow.

[0163] In some embodiments, a double-layer, four-zone heating, ventilation, and / or air conditioning unit 100' is also provided. That is, based on the aforementioned double-layer, double-zone configuration of the heating, ventilation, and / or air conditioning unit 100, the partition walls are further optimized, and auxiliary partition walls are formed on the basis of the central partition wall to divide the shell into four zones.

[0164] Figure 12A A heating, ventilation and / or air conditioning unit 100' according to another embodiment of the present disclosure is shown, which has partition walls 140. Figure 12B A top view of the heating, ventilation and / or air conditioning unit 100' is shown. Figure 13A It shows Figure 12A Internal view of the heating, ventilation and / or air conditioning unit 100' after removing the casing. Figure 13B It shows Figure 13A Another view of the heating, ventilation and / or air conditioning unit 100'. Figure 14 It shows Figure 13A A top view of the heating, ventilation and / or air conditioning unit 100', in which the various sub-zones formed by the layered partition walls 140 are marked.

[0165] Reference Figure 12A and Figure 13A As described above, the heating, ventilation and / or air conditioning unit 100' has, for example, a housing 110 that allows airflow.

[0166] Similarly, the heating, ventilation, and / or air conditioning unit 100' also includes, for example, a layered partition wall 150 disposed inside the housing 110 and including a first partition wall 151 having a first partition portion 1511. The first partition portion 1511 divides a first space V1 and a second space V2 within the housing 110. The specific structure of the first partition wall, the first partition portion, and the associated first and second spaces is as described above. Figures 1 to 3 The details already provided will not be repeated here.

[0167] Furthermore, the heating, ventilation and / or air conditioning unit 100' also includes, for example, a partition wall 140, which includes a central partition wall 141 and two auxiliary partition walls 142.

[0168] Referring to the above Figure 2 The central partition wall 141 refers to the partition that divides the housing 111 into a left half 112 and a right half 113, such as... Figure 12A As shown, it extends, for example, along the vertical centerline of the housing entrance, to divide the housing into a left half 112 and a right half 113.

[0169] Reference Figure 13A and Figure 14The auxiliary partition wall 142 refers to a partition that divides the left half 112 and the right half 113 into two sub-parts, respectively. The auxiliary partition wall may, for example, be connected to the central partition wall and extend parallel to it to divide the left and right halves into two sub-parts, such as... Figure 14 As shown, the auxiliary partition wall 142 divides the left half 112 into a first left half sub-part 1121 and a second left half sub-part 1122, and the right half sub-part into a first right half sub-part 1131 and a second right half sub-part 1132.

[0170] Among them, reference Figure 14 The central partition wall 141 and the two auxiliary partition walls 142 divide the first space V1 into four first space sub-regions V1a, V1b, V1c, and V1d. The central partition wall 141 and the two auxiliary partition walls 142 divide the second space V2 into four second space sub-regions V2a, V2b, V2c, and V2d.

[0171] A portion of the structure of this double-layer, four-zone heating, ventilation, and / or air conditioning unit 100' is identical, for example, to the structure and components described in detail for the aforementioned combined double-layer, two-zone heating, ventilation, and / or air conditioning unit 100, and is capable of, for example, performing the functions of the corresponding components described above. The same reference numerals are used in the accompanying drawings to identify the same or corresponding components in this heating, ventilation, and / or air conditioning unit 100.

[0172] Based on the above, in this application, by setting the heating, ventilation, and / or air conditioning device with layered partition walls, it is possible to achieve layered airflow entry and flow, and to provide different airflow spaces for different layered airflows, which is beneficial for subsequent flow guidance and independent temperature control. Furthermore, by setting it with partition walls, and making the partition walls include a central partition wall and two auxiliary partition walls set on both sides of the central partition wall, the first space and the second space can be divided into four sub-zones by the layered partition walls. Thus, based on the layering of the heating, ventilation, and / or air conditioning device, it is further divided into zones, thereby realizing a double-layer four-zone heating, ventilation, and / or air conditioning device structure. This is beneficial for subsequent guidance of airflow and independent temperature control in the eight sub-zones, thereby greatly improving the control flexibility of the heating, ventilation, and / or air conditioning device, and facilitating the setting of different sub-zones in different working modes, thereby meeting a variety of different functional requirements.

[0173] Figure 15 It shows Figure 12A Structural diagram of partition wall 140 in the middle section. (Refer to...) Figure 15 In some embodiments, the two auxiliary partition walls 142 extend generally parallel to the central partition wall 141.

[0174] By setting the auxiliary partition wall to extend approximately parallel to the central partition wall, the shell can be partitioned in a simple and convenient way, thereby forming the first spatial sub-regions V1a, V1b, V1c, V1d and the second spatial sub-regions V2a, V2b, V2c, V2d.

[0175] Continue to refer to Figure 15 In some embodiments, the downstream ends of the two auxiliary partition walls 142 are provided with a transverse extension wall 143 connecting the two auxiliary partition walls 142.

[0176] The lateral extension wall refers to the component used to connect the two auxiliary partition walls, see reference. Figure 15 Its extension direction is generally perpendicular to the central partition wall and the auxiliary partition wall, and its two ends are respectively joined to the two auxiliary partition walls to connect the two auxiliary partition walls.

[0177] For example, the two auxiliary partition walls 142 and the transverse extension wall 143 can be integrally formed.

[0178] Based on the above, in this application, by providing a transverse extension wall and further providing the transverse extension wall to connect two auxiliary walls, it is possible to better achieve the joint fixation of the two auxiliary walls and facilitate the good positioning of the layered partition wall within the shell.

[0179] In some embodiments, the central partition wall 141 is inserted into the transverse extension wall 143. For example, see reference to... Figure 15 The central partition wall 141 is, for example, inserted into the centerline of the transverse partition wall.

[0180] By setting this transverse partition wall to be inserted into the two auxiliary walls, the assembly and positioning of the central partition wall and the two auxiliary partition walls can be achieved in a simple and convenient way.

[0181] In some embodiments, under the above-described double-layer four-zone structure, the internal structure of the shell can be described more specifically, for example, referring to... Figure 12A and Figure 12B The housing includes, for example, first sub-outlets 160a, 160b, 160c, 160d corresponding to each of the first spatial sub-regions V1a, V1b, V1c, V1d, and second sub-outlets 180a, 180b, 180c, 180d corresponding to each of the second spatial sub-regions V2a, V2b, V2c, V2d.

[0182] For example, in Figure 12A In the example shown, the first sub-outlet is, for example, a foot blowing outlet, and the second sub-outlet is, for example, a ventilation outlet and a defogging outlet.

[0183] And refer to Figure 13A and Figure 14 For each first space sub-zone V1a, V1b, V1c, V1d: the heating, ventilation and / or air conditioning unit also includes a first sub-damper (e.g. 170a, 170b, 170c, 170d respectively), the first sub-damper is disposed inside the housing 110, and the first sub-damper is operably positioned in a first position and a second position.

[0184] It should be understood that the first sub-damper can have the structure and type of the previously described first damper 170, and has a corresponding mode of movement. Specifically, the first sub-damper can be, for example, a plate-shaped damper that can rotate about its own axis of rotation between two extreme positions, and the first position and the second position refer, for example, to the two extreme positions of the first sub-damper, namely, the fully open position and the fully closed position. Specifically, the first position is, for example, the fully open position of the first sub-damper, such as the position where the first sub-damper is fully open and abuts against the first partition wall (e.g., Figure 16 (As shown). The second position is, for example, the fully closed position, that is, the position in which the first sub-damper abuts against the internal structure of the housing and the opening corresponding to the first sub-damper is completely closed.

[0185] The phrase "operably in the first position and the second position" means that the opening position of the first sub-damper can be adjusted according to actual conditions. For example, the position of the first sub-damper can be adjusted by controlling the rotation direction and position of the rotary motor connected to the first sub-damper, or it can be adjusted in other ways to be in the first position or the second position as needed. It should be understood that the embodiments of this disclosure are not limited to the specific adjustment method of the opening position of the first sub-damper.

[0186] When the first sub-damper is in the first position, it engages with the first partition 1511 to guide airflow in the corresponding second space sub-area, which corresponds to the first space sub-area, out through the corresponding second sub-outlet, and to guide airflow in the first space sub-area out through the corresponding first sub-outlet. When the first sub-damper is in the second position, it closes the corresponding first sub-outlet, so that airflow in the first space sub-area and airflow in the corresponding second space sub-area both out through the corresponding second sub-outlet.

[0187] Figure 16 The diagram shows a cross-sectional view of the first right half 1131 of the housing according to an embodiment of the present disclosure. The following will be presented with... Figure 16 Taking the first right half 1131 as an example, we can explain in more detail the situation where the first sub-air damper is in the first position.

[0188] Combined with reference Figure 14 and Figure 15 The first right half sub-section 1131 corresponds, for example, to a first space sub-region V1d and a second space sub-region V2d, and the housing is provided with, for example, a first sub-outlet 160d corresponding to the first space sub-region V1d, which is, for example, a right half front air outlet. The housing is also provided with, for example, a second sub-outlet 180d corresponding to the second space sub-region V2d, which includes, for example, a right half demisting outlet and a right half front ventilation outlet. The first right half sub-section 1131 also includes a first sub-damper 170d corresponding to the first space sub-region V1d.

[0189] and Figure 15 The diagram shows a first sub-damper 170d abutting against a first partition 1151 of a first partition wall to engage with the first partition 1511, thereby guiding airflow in a corresponding second space sub-area V2d corresponding to the first space sub-area V1d out through the second sub-outlet 180d (here, for example, out through the front ventilation outlet), and guiding airflow in the first space sub-area V1d out through the first sub-outlet 160d.

[0190] Based on the above, in this application, on the basis of forming a double-layer four-zone structure heating, ventilation and / or air conditioning device, by adding a first sub-damper to each first space sub-zone, the corresponding first sub-damper can be configured in a first position according to actual needs, so that the airflow in the corresponding first sub-zone flows out through the corresponding first sub-outlet, and the airflow in the corresponding second sub-zone flows out through the corresponding second sub-outlet. The first sub-damper is reused to participate in the separation and guidance of airflow sub-spaces (sub-zones), thereby enabling flexible layout of the airflow type in the sub-outlets corresponding to each sub-zone of the heating, ventilation and / or air conditioning device, and realizing multiple working modes.

[0191] In some embodiments, as previously described, the heating, ventilation and / or air conditioning apparatus further includes a first airflow processing unit 130 disposed within the housing 110 and located upstream of the first partition wall 151.

[0192] As previously described, the first partition wall 151 also has a second partition portion 1512, which divides the third space V3 and the fourth space V4 within the housing 110. A portion of the airflow from the first airflow processing unit 130 enters the third space V3, and the other portion enters the fourth space V4. The second partition portion, the third space, and the fourth space have been previously combined and attached... Figure 5 The details have been explained in detail, so I will not repeat them here.

[0193] Reference Figure 13A The heating, ventilation and / or air conditioning device further includes: a first mixing damper (e.g., first mixing dampers 310a, 310b, 310c, 310d) corresponding to each first space sub-zone V1a, V1b, V1c, V1d and / or a second mixing damper (e.g., second mixing dampers 320a, 320b, 320c, 320d) corresponding to each second space sub-zone V2a, V2b, V2c, V2d.

[0194] Furthermore, the central partition wall 141 and the two auxiliary partition walls 142 divide the third space V3 into four third space sub-regions, for example, third space sub-regions V3a, V3b, V3c, and V3d (in the attached...). Figure 16 , 17 The diagram schematically illustrates the third spatial sub-regions V3c and V3d; the central partition wall 141 and the two auxiliary partition walls 142, for example, divide the fourth space V4 into four fourth spatial sub-regions V4a, V4b, V4c, and V4d (in the attached diagram). Figure 16 , 17 The diagram schematically illustrates the third spatial subregions V4c and V4d.

[0195] Furthermore, similar to the detailed description of the aforementioned double-layer double-zone structure, for each first space sub-zone V1a, V1b, V1c, V1d: when the first mixing damper corresponding to the first space sub-zone is in the fully open position, it will separate the third space sub-zone corresponding to the first space sub-zone from the first space sub-zone.

[0196] For example, taking the first spatial sub-region V1d as an example, refer to Figure 16 For example, a first mixing damper 310d corresponding to the first spatial sub-region V1d is shown. Figure 16 The first mixing damper 310d in the middle is as described above Figure 5 If the space is fully open, then, for example, the third space sub-region V3d can be separated from the first space sub-region V1d.

[0197] Furthermore, similar to the detailed description of the aforementioned double-layer double-zone structure, for each second space sub-zone V2a, V2b, V2c, V2d: when the second mixing damper corresponding to the second space sub-zone is in the fully open position, the fourth space sub-zone corresponding to the second space sub-zone is separated from the second space sub-zone.

[0198] For example, taking the second space subregion V2d as an example, refer to Figure 16 For example, a first mixing damper 320d corresponding to the second spatial sub-region V2d is shown. Figure 16 The second mixing damper 320d in the middle is as described above Figure 5 If the space is fully open, then, for example, the fourth space sub-region V4d can be separated from the second space sub-region V2d.

[0199] Based on the above, in this application, by configuring the housing to include a first mixing damper corresponding to each first spatial sub-region and / or a second mixing damper corresponding to each second spatial sub-region and a first airflow processing unit (e.g., a heater), the temperature of the airflow entering the corresponding first spatial sub-region can be adjusted according to actual needs by adjusting the opening position of the first mixing damper corresponding to the first spatial sub-region; and the temperature of the airflow entering the second spatial sub-region can be adjusted by adjusting the opening position of the second mixing damper corresponding to the second spatial sub-region, thereby achieving independent adjustment of the airflow temperature of different layers and different sub-regions after layering and partitioning. Furthermore, multiple third and fourth spatial sub-regions are separated within the housing by a second partition and a partitioning wall. When the corresponding first mixing damper is in the fully closed position, the third spatial sub-region is separated from the first spatial sub-region; when the corresponding second mixing damper is in the fully closed position, the fourth spatial sub-region is separated from the second spatial sub-region. This allows the first and second mixing dampers to be reused as spacers between adjacent spaces, thereby optimizing the structural layout within the housing.

[0200] In some embodiments, the layered partition wall 150 further includes a second partition wall 152. The second partition wall 152 is located upstream of the first airflow processing unit 130, and separates a fifth space V5 and a sixth space V6 within the housing 110. Part of the airflow passing through the first airflow processing unit 130 originates from the fifth space V5, and another part originates from the sixth space V6. It should be understood that the first airflow processing unit, the second partition wall, and the fifth and sixth spaces have been described in detail above and will not be repeated here.

[0201] Specifically, for each first spatial sub-region V1a, V1b, V1c, V1d: when the first mixing damper corresponding to that first spatial sub-region is in the fully closed position, the fifth space V5 is separated from that first spatial sub-region. And for each second spatial sub-region V2a, V2b, V2c, V2d: when the second mixing damper corresponding to that second spatial sub-region is in the fully closed position, the sixth space V6 is separated from that second spatial sub-region.

[0202] Figure 17 A cross-sectional view of the second right half of the sub-part 1132 according to an embodiment of the present disclosure is shown. The following will refer to... Figure 17 The closing positions of the first and second mixing dampers will be described in more detail.

[0203] Reference Figure 17The second right sub-section 1132 corresponds, for example, to the first space sub-region V1c and the second space sub-region V2c. The housing contains, for example, a first sub-outlet 160c corresponding to the first space sub-region V1c, which is, for example, the rear foot outlet of the right half. The housing also contains, for example, a second sub-outlet 180c corresponding to the second space sub-region V2c. The second sub-outlet 180c includes, for example, a right half demisting outlet and a right half rear ventilation outlet. The second right sub-section 1132 also includes a first sub-damper 170c corresponding to the first space sub-region V1c.

[0204] and Figure 17 The diagram shows that when the first mixing damper 310c corresponding to the first spatial sub-region is in the fully closed position, it separates the fifth space V5 from the first spatial sub-region V1c. It also shows that when the second mixing damper 320c corresponding to the second spatial sub-region is in the fully closed position, it separates the sixth space V6 from the second spatial sub-region V2c.

[0205] Based on the above, in this application, by setting the layered partition wall to further include a second partition wall, a fifth space and a sixth space are further divided upstream of the first airflow processing unit via the second partition wall. This allows for the setting of different airflow spaces corresponding to different layered airflows upstream of the first airflow processing unit, thereby providing good layered airflow spaces in both the upper and lower flow paths of the first airflow processing unit. Furthermore, by setting the first mixing damper corresponding to the first space sub-area to be in the fully closed position, the fifth space is separated from the corresponding first space sub-area; and by setting the second mixing damper corresponding to the second space sub-area to be in the fully closed position, the sixth space is separated from the second space sub-area. This allows for the maximum reuse of the first mixing damper corresponding to each first space sub-area and the second mixing damper corresponding to each second space sub-area to achieve the separation and connection of each space according to actual needs. This facilitates the flexible selection and setting of airflow paths and the guidance of airflow direction, and enables the device to achieve multiple operating modes.

[0206] In some embodiments, as previously described, the heating, ventilation, and / or air conditioning unit further includes a second airflow processing unit 120. The second airflow processing unit 120 is disposed within the housing 110 and located upstream of the second partition wall 152. A portion of the airflow passing through the second airflow processing unit 120 enters the fifth space V5, and another portion enters the sixth space V6. The second airflow processing unit 120 and its associated connection features with the second partition wall have been described in detail previously in conjunction with the dual-layer, dual-zone heating, ventilation, and / or air conditioning unit, and will not be repeated here.

[0207] Figure 18A structural diagram of a heating, ventilation and / or air conditioning unit 100' according to an embodiment of the present disclosure is shown after removing the housing.

[0208] In some embodiments, refer to Figure 18 In the second space sub-area corresponding to the transverse extension wall 143, the heating, ventilation and / or air conditioning device 100' is also provided with a second sub-air damper.

[0209] The second spatial sub-region corresponding to the lateral extension wall 143 refers to the second spatial sub-region through which the lateral extension wall extends. For example, referring to... Figure 14 and Figure 18 It can be seen that, in Figure 14 and Figure 18 In the heating, ventilation and / or air conditioning apparatus shown, the lateral extension wall extends, for example, in the second spatial sub-regions V2b and V2c, i.e., the second spatial sub-regions V2b and V2c are the second spatial sub-regions corresponding to the lateral extension wall 143.

[0210] The second sub-damper refers to a second sub-damper component disposed in the second spatial sub-area corresponding to the transversely extending wall, which may be, for example, a butterfly damper. Embodiments of this disclosure are not limited to the specific type of the second sub-damper.

[0211] For example, comprehensive reference Figure 14 and Figure 18 The heating, ventilation and / or air conditioning unit shown has, for example, a second sub-damper in the second space sub-area V2b, V2c corresponding to the transverse extension wall. Specifically, a second sub-damper 171b is provided in the second space sub-area V2b, and a second sub-damper 171c is provided in the second space V2c.

[0212] Furthermore, for each second space sub-region corresponding to the lateral extension wall: when the second sub-damper is in the fully closed position, the second sub-damper engages with the first partition and the lateral extension wall to divide the second space sub-region into a second space first sub-region and a second space second sub-region.

[0213] It should be understood that the fully closed position refers to the position where the second sub-air damper separates the second space sub-area.

[0214] The second space first sub-region and the second space second sub-region refer to two areas within the second space sub-region. It should be understood that the embodiments of this disclosure are not limited by the specific spatial volume and spatial location of the second space first sub-region and the second space second sub-region.

[0215] Figure 19A cross-sectional view of the second right half of the sub-part 1132 according to an embodiment of the present disclosure is shown, wherein the first sub-region of the second space and the second sub-region of the second space are marked. (Refer to...) Figure 19 Next, we will take the second right half of the sub-part 1132 as an example to give a more specific explanation of the second sub-air damper.

[0216] like Figure 17 and Figure 19 As shown, the second right half of the sub-part 1132 corresponds to the second subspace V2c, and Figure 19 The diagram illustrates, for example, a second sub-damper 171c in a fully closed position within the second subspace V2c. This second sub-damper 171c is, for example, a butterfly damper, and the fully closed position means that the second sub-damper is in a substantially horizontal position. In this fully closed position, one end of the second sub-damper 171c engages with the aforementioned first partition 1511, and the other end engages, for example, with the transverse extension wall 143 in the partition wall. This divides the second subspace into a first sub-region V2c-1 and a second sub-region V2c-2 via the first partition 1511, the second sub-damper 171c, and the transverse extension wall 143. The first and second sub-regions of the second space are, for example, connected to different second sub-outlets. Specifically, the first sub-region of the second space may be connected to, for example, a front ventilation sub-outlet and a demisting sub-outlet, and the second sub-region of the second space may be connected to, for example, a rear ventilation sub-outlet.

[0217] Based on the above, in this application, by setting a second sub-damper in the second space sub-area corresponding to the transverse extension wall, and setting the second sub-damper to engage with the first partition and the transverse extension wall when fully closed, the second space sub-area is divided into a second space first sub-area and a second space second sub-area. This allows for flexible further division of the internal space of the shell through the cooperation of the set second sub-damper with the internal structure of the shell and the partition wall structure. This facilitates the flexible setting of the flow path of the stratified airflow in different areas according to actual needs, and is conducive to realizing multiple working modes.

[0218] In some embodiments, further reference is made to Figure 19 The second sub-outlet may, for example, include a ventilation sub-outlet. Further, the ventilation sub-outlet may also include a front ventilation sub-outlet and a rear ventilation sub-outlet.

[0219] In the second space sub-area corresponding to the transverse extension wall 143, the heating, ventilation and / or air conditioning device is further provided, for example, with a third sub-damper. The third sub-damper may be, for example, a butterfly damper, or may be of other types depending on actual needs.

[0220] Furthermore, for each second space sub-region corresponding to the lateral extension wall: when the third sub-damper is in the fully closed position, the third sub-damper engages with the housing to close the corresponding ventilation sub-outlet.

[0221] The fully closed position of the third sub-damper refers to the position where the third sub-damper is used to close the corresponding ventilation sub-outlet.

[0222] For example, refer to Figure 19 ,exist Figure 19 In the second right half of the sub-section 1132 shown, the second sub-outlet includes, for example, a demisting sub-outlet 181c, a front ventilation sub-outlet 1821c, and a rear ventilation sub-outlet 1822c. The third sub-damper 172c is, for example, located near the rear ventilation sub-outlet 1822c and is a butterfly-shaped damper. When the third sub-damper is in the fully closed position, the two butterfly-shaped blades of the third sub-damper engage with the inner wall of the housing to form spacers, thereby closing the corresponding rear ventilation sub-outlet 1822c.

[0223] Based on the above, in this application, by setting a third sub-damper in the second space sub-area corresponding to the transverse extension wall, and setting the third sub-damper to be in the fully closed position, the third sub-damper cooperates with the housing to close the corresponding ventilation sub-outlet, so that the corresponding ventilation sub-outlet of the second space sub-area can be closed by adjusting the third sub-damper according to actual needs, thereby facilitating the flexible setting of the airflow path and output outlet according to actual needs, thereby realizing a multi-mode and multi-functional heating, ventilation and / or air conditioning device.

[0224] The following section will provide a more detailed explanation of the structure and the interrelationships between the components of the double-layer, four-zone heating, ventilation, and / or air conditioning unit 100', in conjunction with its application in multiple different operating modes.

[0225] The double-layer four-zone system refers to the heating, ventilation and / or air conditioning unit 100' having four sub-parts (first left half, second left half, first right half, and second right half) symmetrically arranged along the plane of the central partition wall, divided by partition walls, and having two layers of airflow inlets (upper airflow inlet and lower airflow inlet) divided by layer partition walls. That is, it has eight independent airflow inlets (which can, for example, be for the same type of airflow or for different types of airflow). Inside the housing, corresponding airflow paths and temperature control dampers are divided for each of the eight independent airflow inlets, thereby enabling independent temperature regulation of each intake airflow entering from the eight independent airflow inlets and guiding it to different outlet channels according to different modes. Furthermore, through the corresponding outlet configuration, the heating, ventilation, and / or air conditioning unit has independent foot-blowing outlets, ventilation outlets, and defrosting outlets in four directions: left front, left rear, right front, and right rear. Each foot-blowing outlet, ventilation outlet, and defrosting outlet can output different types, temperatures, and flow rates of airflow. This allows for the provision of independent foot-blowing, ventilation, and defrosting functions to the front passenger side (right side), front driver side (left side), rear left passenger side, and rear right passenger side of the vehicle.

[0226] For example, the double-layer four-zone heating, ventilation and / or air conditioning unit 100' described herein has the aforementioned combination. Figures 12A to 19 The structure of the heating, ventilation and / or air conditioning unit 100' described in detail may include, for example, the housing 110, the layered partition wall 150, the first processing unit 120, and the second processing unit 130 as described above, and has corresponding connection structures, which will not be repeated here.

[0227] And the heating, ventilation and / or air conditioning unit 100' includes, for example, such as Figure 15 The partition wall 140 shown includes a central partition wall, auxiliary partition walls extending parallel to the central partition wall, and a transverse extension wall. The central partition wall 141 divides the heating, ventilation, and / or air conditioning unit 100' into a left half 112 and a right half 113 symmetrically arranged along the line of the central partition wall. The auxiliary partition wall 142 divides the left half 112 into a first left sub-part 1121 and a second left sub-part 1122, and the right sub-part into a first right sub-part 1131 and a second right sub-part 1132. The central partition wall 141 and the two auxiliary partition walls 142 divide the first space V1 into four first space sub-regions V1a, V1b, V1c, and V1d, and the second space V2 into four second space sub-regions V2a, V2b, V2c, and V2d.

[0228] Furthermore, each first spatial sub-region has a corresponding first sub-outlet. Specifically, for example, the first spatial sub-region V1a in the first left half sub-section 1121 has a left half front air outlet; the first spatial sub-region V1b in the second left half sub-section 1121 has a left half rear air outlet; the first spatial sub-region V1d in the first right half sub-section 1131 has a right half front air outlet; and the first spatial sub-region V1c in the second right half sub-section 1131 has a right half rear air outlet.

[0229] Furthermore, each second space sub-region has a corresponding second sub-outlet. In this example, the second sub-outlet includes, for example, a demisting sub-outlet and a ventilation sub-outlet provided for each second space sub-region. Specifically, for the ventilation sub-outlet, for example, for the second space sub-region V2a in the first left half sub-section 1121, it has a left half front ventilation sub-outlet; for the second space sub-region V2b in the second left half sub-section 1121, it has a left half rear ventilation sub-outlet; for the second space sub-region V2d in the first right half sub-section 1131, it has a right half front ventilation sub-outlet; and for the second space sub-region V2c in the second right half sub-section 1131, it has a right half rear ventilation sub-outlet.

[0230] Considering the symmetry between the left and right halves and the corresponding positions of the sub-outlets, it is known that the left and right halves have the same structure. Furthermore, in the same mode, the first left sub-part and the first right sub-part can, for example, have the same configuration and the same airflow path; similarly, the second left sub-part and the second right sub-part can, for example, have the same configuration and the same airflow path. Therefore, in the subsequent descriptions of each operating mode, the right sub-part (including the first and second right sub-parts) will be used as an example to describe its specific structural configuration and airflow path. Those skilled in the art should understand that, based on the symmetry, the left half can be configured accordingly to be in the corresponding mode and achieve the corresponding function.

[0231] Foot blowing and ventilation dual modes

[0232] Figure 20A A cross-sectional view of the first right half 1131 of a heating, ventilation and / or air conditioning unit 100' is shown, wherein the heating, ventilation and / or air conditioning unit 100' is in foot ventilation dual mode; Figure 20B A cross-sectional view of the second right half 1132 of a heating, ventilation and / or air conditioning unit 100' is shown, wherein the heating, ventilation and / or air conditioning unit 100' is in foot ventilation dual mode.

[0233] Reference Figure 20AWhen the heating, ventilation, and / or air conditioning unit 100' is in foot-blowing ventilation dual mode, the first right half 1131 corresponds, for example, to a first space sub-region V1d and a second space sub-region V2d, and the housing is provided with, for example, a first sub-outlet 160d corresponding to the first space sub-region V1d, which is here the right half front foot-blowing sub-outlet 161d. The housing is also provided with, for example, a second sub-outlet 180d corresponding to the second space sub-region V2d, which includes, for example, a right half demisting sub-outlet 181d and a right half front ventilation sub-outlet 1821d. The first right half sub-section 1131 also includes a first sub-damper 170d corresponding to the first space sub-region V1d.

[0234] Reference Figure 20A When the heating, ventilation, and / or air conditioning unit 100 is in foot-blowing ventilation dual mode, the first sub-damper 170d in the first right half 1131 is configured in the first position to fully open the front foot-blowing sub-outlet 161d of the right half and engage with the first partition to guide airflow. The demisting sub-damper 191d will be in the fully closed position to fully close the demisting sub-outlet 181d, and the front ventilation sub-damper 1921d will be open. The specific opening position can be adjusted according to actual needs to allow the outlet to open at the desired degree.

[0235] At this point, for example, the opening degrees of the first mixing damper 310d and the second mixing damper 320d can be further adjusted to control the proportion of stratified airflow flowing through and bypassing the first airflow processing unit 120 (heater). Figure 20A In the example shown, the first mixing damper 310d and the second mixing damper 320d are both in the middle position, for example.

[0236] At this time, for example, internal recirculated air is introduced into the upper layer of the inlet of the first right half of the casing, and for example, fresh air is introduced into the lower layer of the inlet of the first right half of the casing. The airflow within the casing is as follows: For the upper airflow, the upper intake airflow (here, the internal recirculated air intake airflow) F1i_d enters from the upper part of the inlet, first passes through the second airflow processing unit 130 (evaporator), and then the upper intake airflow F1i_d is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120, enters the fifth space V5, and directly enters the first space sub-region V1d from the left side of the first mixing damper 310d (e.g., Figure 20A (The airflow direction is shown by dashed lines). The second airflow branch of the upper intake airflow F1i_d will pass through the first airflow processing unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space sub-region V3d through the first airflow processing unit 120, and enter the first space sub-region V1d via the right side of the first mixing damper 310d (as shown in the image). Figure 20A(The airflow direction is shown by the dotted line in the figure). The second airflow branch passing through the first airflow processing unit 120 will be heated by the heater to have a higher temperature than the first airflow branch. Subsequently, in the first space sub-region V1d, the two airflow branches will mix and form the upper output airflow (here, the internal recirculation air output airflow) F1o_d (it should be understood that the arrow in the figure is only schematic, and in fact, this output airflow is output through the side opening of the housing). At this time, the first sub-damper 170d in the first position will engage with the first partition and guide the upper output airflow F1o_d in the first space sub-region V1d to flow out through the right half front blower outlet 161d.

[0237] For the lower airflow, when fresh air is introduced, the lower air intake airflow (here, the fresh air intake airflow) F2i_d enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower air intake airflow F2i_d is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120 and enters the sixth space V6, directly entering the second space sub-region V2d from the right side of the second mixing damper 320d. Figure 20A (The airflow direction is shown by dashed lines). The second airflow branch of the lower intake airflow F2i_d will pass through the first airflow processing unit (heater) 120, specifically, it will enter the sixth space V6, then enter the fourth space sub-region V4d through the first airflow processing unit 120, and finally enter the second space sub-region V2d from the left side of the second mixing damper 320d (as shown by dashed lines). Figure 20A (The airflow direction is shown as a dotted line in the diagram). The second airflow branch passing through the first airflow processing unit 120 will be heated by the heater to have a higher temperature than the first airflow branch. Subsequently, in the second space V2, the two airflow branches will mix and form a lower output airflow F2o_d. At this time, the first sub-damper 170d, which is in the first position, will engage with the first partition and guide the lower output airflow F2o_d in the second space sub-region V2d to be output through the right half front ventilation sub-outlet 1821d.

[0238] Reference Figure 20B When the heating, ventilation, and / or air conditioning unit 100' is in foot-blowing ventilation dual mode, the first sub-damper 170c in the second right half 1132 is configured in the first position to fully open the right half rear foot-blowing sub-outlet 162c and engage with the first partition to guide airflow. The demisting sub-damper 191c will be in the fully closed position to fully close the demisting sub-outlet 181c, and the third sub-damper (here, the front ventilation sub-damper) 172c is, for example, in the open position. The specific opening position can be adjusted according to actual needs to allow the right half rear ventilation sub-outlet 1822c to open at the desired opening degree.

[0239] At this point, for example, the opening degrees of the first mixing damper 310c and the second mixing damper 320c can be further adjusted to control the proportion of stratified airflow flowing through and bypassing the first airflow processing unit 120 (heater). Figure 20B In the example shown, the first mixing damper 310c and the second mixing damper 320c are both in the middle position, for example.

[0240] At this time, for example, internal recirculated air is introduced into the upper layer of the inlet of the second right half of the casing, and for example, fresh air is introduced into the lower layer of the inlet of the second right half of the casing. The airflow within the casing is as follows: For the upper airflow, the upper intake airflow (here, the internal recirculated air intake airflow) F1i_c enters from the upper part of the inlet, first passing through the second airflow processing unit 130 (evaporator). Afterward, the upper intake airflow F1i_c is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120, enters the fifth space V5, and directly enters the first space sub-region V1c (e.g., from the left side of the first mixing damper 310c) from the left side of the first mixing damper 310c. Figure 20B (The airflow direction is shown by dashed lines). The second airflow branch of the upper intake airflow F1i_c will pass through the first airflow processing unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space sub-region V3c through the first airflow processing unit 120, and enter the first space sub-region V1c via the right side of the first mixing damper 310c (as shown by dashed lines). Figure 20B (The airflow direction is shown in the dotted line). The second airflow branch passing through the first airflow processing unit 120 will be heated by the heater to have a higher temperature than the first airflow branch. Subsequently, in the first space sub-region V1c, the two airflow branches will mix and form the upper output airflow (here, the internal recirculation air output airflow) F1o_c. At this time, the first sub-damper 170c in the first position will engage with the first partition and guide the upper output airflow F1o_c in the first space sub-region V1c to flow out through the right half rear foot outlet 162c.

[0241] For the lower airflow, when fresh air is introduced, the lower air intake airflow (here, the fresh air intake airflow) F2i_c enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower air intake airflow F2i_c is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120 and enters the sixth space V6, directly entering the second space sub-region V2c from the right side of the second mixing damper 320c. Figure 20B(The airflow direction is shown by the dashed line). The second airflow branch of the lower intake airflow F2i_c will pass through the first airflow processing unit (heater) 120, specifically, it will enter the sixth space V6, then enter the fourth space sub-region V4c through the first airflow processing unit 120, and finally enter the second space sub-region V2c from the left side of the second mixing damper 320c (as shown by the dashed line). Figure 20B (The airflow direction is shown by a dotted line in the diagram). The second airflow branch passing through the first airflow processing unit 120 will be heated by the heater to have a higher temperature than the first airflow branch. Subsequently, in the second space sub-region V2c, the two airflow branches will mix and form a lower output airflow F2o_c. At this time, the second sub-damper 171c, which is in a fully closed position, will engage with the first partition and the lateral extension wall to separate the second space first sub-region V2c-1 and the second space second sub-region V2c-2 in the second space sub-region V2c. The lower output airflow F2o_c in the second space V2c is guided to flow only in the second space first sub-region V2c-1 and is output through the right half rear ventilation sub-outlet 1822c.

[0242] It should be understood that, considering that the first mixing damper and the second mixing damper are respectively set for each first sub-zone and the second sub-zone, and both have the function of temperature regulation, the process of temperature regulation via the first mixing damper and the second mixing damper will not be described again in the following text.

[0243] Based on this, the integrated design of layered and zoned partitions allows for the stratified entry of internal circulating air and fresh air with corresponding airflow space. Furthermore, the partitioned partitions and shell structure enable independent temperature control from the front, back, left, and right sides, building upon the existing independent temperature control (as explained in the previous description of the double-layer, double-zone configuration). Specifically, as detailed in the previous description of the right half's operating mode (based on a symmetrical structure, the left half can have corresponding airflow pathways), different airflow paths, damper opening controls, and independent temperature control can be implemented for the front and rear sub-outlets of the right half, as well as for the front and rear ventilation sub-outlets of the right half. This results in independent foot outlets and ventilation outlets in all four directions (left front, left rear, right front, and right rear), each capable of outputting different types, temperatures, and flow rates of airflow.

[0244] Defogging priority mode

[0245] Figure 21AA cross-sectional view of the first right half 1131 of a heating, ventilation and / or air conditioning unit 100' is shown, wherein the heating, ventilation and / or air conditioning unit 100' is in a defogging priority mode; Figure 21B A cross-sectional view of the second right half 1132 of a heating, ventilation and / or air conditioning unit 100' is shown, wherein the heating, ventilation and / or air conditioning unit 100' is in a defogging priority mode.

[0246] Reference Figure 21A When the heating, ventilation, and / or air conditioning unit 100' is in demisting priority mode, the first sub-damper 170d in the first right half 1131 is configured in the second position to completely close the right half front air outlet 161d. The demisting sub-damper 191d will be in the fully open position to fully open the demisting outlet 181d, and the front ventilation sub-damper 1921d will be closed to close the right half front ventilation outlet 1821d.

[0247] At this point, for example, the opening degrees of the first mixing damper 310d and the second mixing damper 320d can be further adjusted to control the proportion of stratified airflow flowing through and bypassing the first airflow processing unit 120 (heater). Figure 21A In the example shown, the first mixing damper 310d and the second mixing damper 320d are both in the middle position, for example.

[0248] At this time, fresh air is introduced into both the upper and lower layers of the inlet of the first right half of the casing, and the airflow within the casing is as follows: For the upper airflow, the upper intake airflow (here, the fresh air intake airflow) F1i_d enters from the upper part of the inlet, first passes through the second airflow processing unit 130 (evaporator), and then the upper intake airflow F1i_d is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120, enters the fifth space V5, and directly enters the first space sub-region V1d from the left side of the first mixing damper 310d (e.g., Figure 21A (The airflow direction is shown by dashed lines). The second airflow branch of the upper intake airflow F1i_d will pass through the first airflow processing unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space sub-region V3d through the first airflow processing unit 120, and enter the first space sub-region V1d via the right side of the first mixing damper 310d (as shown in the image). Figure 21A (The direction of airflow is indicated by dotted lines).

[0249] For the lower airflow, when fresh air is introduced, the lower air intake airflow (here, the fresh air intake airflow) F2i_d enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower air intake airflow F2i_d is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120 and enters the sixth space V6, directly entering the second space sub-region V2d from the right side of the second mixing damper 320d. Figure 21A (The airflow direction is shown by dashed lines). The second airflow branch of the lower intake airflow F2i_d will pass through the first airflow processing unit (heater) 120, specifically, it will enter the sixth space V6, then enter the fourth space sub-region V4d through the first airflow processing unit 120, and finally enter the second space sub-region V2d from the left side of the second mixing damper 320d (as shown by dashed lines). Figure 21A (The direction of airflow is indicated by dotted lines in the diagram).

[0250] At this time, since the first sub-damper 170d in the second position completely closes the right half front air outlet 161d, the upper air intake airflow F1i_d in the first space sub-region V1d and the lower air intake airflow F2i_d in the second space sub-region V2d together form the output airflow Fo_d, and the output airflow Fo_d is output through the demisting outlet 181d.

[0251] Reference Figure 21B When the heating, ventilation, and / or air conditioning unit 100' is in demisting priority mode, the first sub-damper 170c in the second right half 1132 is configured in the second position to completely close the right half rear air outlet 162c. The demisting sub-damper 191c will be in the fully open position to fully open the demisting outlet 181c, and the third sub-damper (here, the front ventilation sub-damper) 172c will be in the fully closed position, for example, to engage with the inner wall of the housing and completely close the right half rear ventilation outlet 1822c.

[0252] At this time, fresh air is introduced into both the upper and lower layers of the inlet of the second right half of the casing, and the airflow within the casing is as follows: For the upper airflow, the upper intake airflow (here, the fresh air intake airflow) F1i_c enters from the upper part of the inlet, first passing through the second airflow processing unit 130 (evaporator). Then, the upper intake airflow F1i_c is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120, enters the fifth space V5, and directly enters the first space sub-region V1c (e.g., from the left side of the first mixing damper 310c) from the left side of the first mixing damper 310c. Figure 21B(The airflow direction is shown by dashed lines). The second airflow branch of the upper intake airflow F1i_c will pass through the first airflow processing unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space sub-region V3c through the first airflow processing unit 120, and enter the first space sub-region V1c via the right side of the first mixing damper 310c (as shown by dashed lines). Figure 21B (The direction of airflow is indicated by dotted lines).

[0253] For the lower airflow, when fresh air is introduced, the lower air intake airflow (here, the fresh air intake airflow) F2i_c enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower air intake airflow F2i_c is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120 and enters the sixth space V6, directly from the right side of the second mixing damper 320c into the first sub-region V2c-1 of the second space. Figure 21B (The airflow direction is shown by dashed lines). The second airflow branch of the lower intake airflow F2i_c will pass through the first airflow processing unit (heater) 120, specifically, it will enter the sixth space V6, then enter the fourth space sub-zone V4c through the first airflow processing unit 120, and finally enter the second space first sub-zone V2c-1 from the left side of the second mixing damper 320c (as shown in the image). Figure 21B (The airflow direction is shown by the dotted line in the diagram). At this time, the second sub-damper 171c, which is in the open position, will cooperate with the first partition to guide the intake airflow, so that the intake airflow (including two airflow branches) enters the second sub-zone V2c-2 of the second space from the first sub-zone V2c-1 of the second space through the path between the second sub-damper 171c and the first partition.

[0254] At this time, since the first sub-damper 170c in the second position completely closes the right half of the rear air outlet 162c, the upper air intake airflow F1i_c in the first space sub-region V1c and the lower air intake airflow F2i_c in the second space sub-region V2c together form the output airflow Fo_c, and the output airflow Fo_c is output through the demisting outlet 181c.

[0255] Based on this, in the defogging priority mode, the corresponding air outlet is completely closed by the first sub-air damper in each first space sub-zone, the right half rear ventilation outlet is completely closed by the third sub-air damper, and the airflow is guided by the second sub-air damper and the first partition, so that, for example, the upper air intake airflow and the lower air intake airflow are both output through the defogging outlet.

[0256] Foot blowing and defogging dual modes

[0257] Figure 22AA cross-sectional view of the first right half 1131 of a heating, ventilation and / or air conditioning unit 100' is shown, wherein the heating, ventilation and / or air conditioning unit 100' is in a foot blowing and defogging dual mode; Figure 22B A cross-sectional view of the second right half 1132 of a heating, ventilation and / or air conditioning unit 100' is shown, wherein the heating, ventilation and / or air conditioning unit 100' is in a foot blowing and defogging dual mode.

[0258] Reference Figure 22A When the heating, ventilation, and / or air conditioning unit 100' is in the foot blowing and demisting dual mode, the first sub-damper 170d in the first right half 1131 is configured in the first position to fully open the right half front foot blowing sub-outlet 161d and engage with the first partition to guide airflow. The demisting sub-damper 191d will be in the open position to open the demisting sub-outlet 181d. The specific opening position can be adjusted according to actual needs to open the outlet to the desired degree. The front ventilation sub-damper 1921d is in the fully closed position to close the right half front ventilation sub-outlet 1821d.

[0259] At this point, for example, the opening degrees of the first mixing damper 310d and the second mixing damper 320d can be further adjusted to control the proportion of stratified airflow flowing through and bypassing the first airflow processing unit 120 (heater). Figure 22A In the example shown, the first mixing damper 310d and the second mixing damper 320d are both in the middle position, for example.

[0260] At this time, for example, internal recirculated air is introduced into the upper layer of the inlet of the first right half of the casing, and for example, fresh air is introduced into the lower layer of the inlet of the first right half of the casing. The airflow within the casing is as follows: For the upper airflow, the upper intake airflow (here, the internal recirculated air intake airflow) F1i_d enters from the upper part of the inlet, first passes through the second airflow processing unit 130 (evaporator), and then the upper intake airflow F1i_d is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120, enters the fifth space V5, and directly enters the first space sub-region V1d from the left side of the first mixing damper 310d (e.g., Figure 22A (The airflow direction is shown by dashed lines). The second airflow branch of the upper intake airflow F1i_d will pass through the first airflow processing unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space sub-region V3d through the first airflow processing unit 120, and enter the first space sub-region V1d via the right side of the first mixing damper 310d (as shown in the image). Figure 22A(The airflow direction is shown in the dotted line). Subsequently, in the first spatial sub-region V1d, the two airflow branches will mix and form the upper output airflow (here, the internal recirculation air output airflow) F1o_d. At this time, the first sub-damper 170d, which is in the first position, will engage with the first partition and guide the upper output airflow F1o_d in the first spatial sub-region V1d to flow out through the right half of the front blower outlet 161d.

[0261] For the lower airflow, when fresh air is introduced, the lower air intake airflow (here, the fresh air intake airflow) F2i_d enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower air intake airflow F2i_d is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120 and enters the sixth space V6, directly entering the second space sub-region V2d from the right side of the second mixing damper 320d. Figure 22A (The airflow direction is shown by dashed lines). The second airflow branch of the lower intake airflow F2i_d will pass through the first airflow processing unit (heater) 120, specifically, it will enter the sixth space V6, then enter the fourth space sub-region V4d through the first airflow processing unit 120, and finally enter the second space sub-region V2d from the left side of the second mixing damper 320d (as shown by dashed lines). Figure 22A (The airflow direction is shown by the dotted line in the diagram). Subsequently, in the first spatial sub-region V2d, the two airflow branches will mix and form a lower output airflow (here, a fresh air output airflow) F2o_d, which is output via the demisting outlet 181d.

[0262] Reference Figure 22B In this foot-blowing and defogging dual mode, the first sub-damper 170c in the second right half 1132 is configured in the first position to fully open the right half rear foot-blowing sub-outlet 162c and engage with the first partition to guide airflow. The defogging sub-damper 191c will be in the open position to open the defogging sub-outlet 181c. The specific opening position can be adjusted according to actual needs to allow the defogging sub-outlet 181c to open at the desired degree. The third sub-damper (here, the front ventilation sub-damper) 172c is, for example, in the fully closed position to close the right half rear ventilation sub-outlet 1822c.

[0263] At this time, for example, internal recirculated air is introduced into the upper layer of the inlet of the second right half of the casing, and for example, fresh air is introduced into the lower layer of the inlet of the second right half of the casing. The airflow within the casing is as follows: For the upper airflow, the upper intake airflow (here, the internal recirculated air intake airflow) F1i_c enters from the upper part of the inlet, first passing through the second airflow processing unit 130 (evaporator). Afterward, the upper intake airflow F1i_c is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120, enters the fifth space V5, and directly enters the first space sub-region V1c (e.g., from the left side of the first mixing damper 310c) from the left side of the first mixing damper 310c. Figure 22B (The airflow direction is shown by dashed lines). The second airflow branch of the upper intake airflow F1i_c will pass through the first airflow processing unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space sub-region V3c through the first airflow processing unit 120, and enter the first space sub-region V1c via the right side of the first mixing damper 310c (as shown by dashed lines). Figure 22B (The airflow direction is shown in the dotted line). Subsequently, in the first spatial sub-region V1c, the two airflow branches will mix and form the upper output airflow (here, the internal recirculation air output airflow) F1o_c. At this time, the first sub-damper 170c, which is in the first position, will engage with the first partition and guide the upper output airflow F1o_c in the first spatial sub-region V1c to flow out through the right half of the rear foot outlet 162c.

[0264] For the lower-level airflow, in the current Figure 22B In the case shown, the second sub-damper 171c is, for example, in a completely closed state to block the first sub-zone V2c-1 and the second sub-zone V2c-2 of the second space. At this time, the lower air intake airflow will not enter the second sub-zone V2c-2 of the second space, nor will it be output through the demisting outlet 181c.

[0265] At this point, the defogging function can, for example, be based solely on the aforementioned Figure 22A This is achieved by the lower-level output airflow F2o_d from the demisting outlet 181d. However, it should be understood that, depending on the actual situation, such as when a further increase in the demisting airflow is required, the second sub-damper 171c can also be configured to, for example, be in a position where... Figure 21B The open position shown is designed to engage with the inner wall of the housing and guide the lower air intake airflow through the demister outlet 181c, thereby enabling the demister outlet 181c and the demister outlet 181d to jointly output the demister airflow for a more powerful demister function.

[0266] Based on this, in the dual-mode foot blowing and defogging, on the one hand, the division of the first and second space sub-zones is achieved through the cooperation of the first sub-air damper and the first partition in each first space sub-zone, and the upper internal circulating air is guided to be output through the corresponding front / rear foot sub-outlets to achieve the function of blowing the feet with internal circulating air. On the other hand, the cooperation of the second sub-air damper in each second space sub-zone with the inner wall allows the lower fresh air to be used to achieve the function of defogging.

[0267] Foot blowing mode

[0268] Figure 23A A cross-sectional view of the first right half 1131 of a heating, ventilation and / or air conditioning unit 100' is shown, wherein the heating, ventilation and / or air conditioning unit 100' is in foot blowing mode; Figure 23B A cross-sectional view of the second right half 1132 of a heating, ventilation and / or air conditioning unit 100' is shown, wherein the heating, ventilation and / or air conditioning unit 100' is in foot-blowing mode.

[0269] Reference Figure 23A When the heating, ventilation, and / or air conditioning unit 100' is in foot-blowing mode, the first sub-damper 170d in the first right half 1131 is configured in the first position to fully open the front foot-blowing sub-outlet 161d of the right half and engage with the first partition to guide airflow. The defogging sub-damper 191d will be in the open position to slightly open the defogging sub-outlet 181d to prevent fogging on the glass during foot-blowing. In this case, the airflow path and structural configuration in this foot-blowing mode are the same as in the foot-blowing and defogging dual-mode, and will not be described again here.

[0270] Reference Figure 22B In this foot-blowing mode, the first sub-damper 170c in the second right half 1132 is configured in the first position to fully open the rear foot-blowing sub-outlet 162c of the right half and engage with the first partition to guide the airflow. The demisting sub-damper 191c will be in the open position to open the demisting sub-outlet 181c. The specific opening position can be adjusted according to actual needs to make the demisting sub-outlet 181c open at the desired opening degree. The third sub-damper (here, as the front ventilation sub-damper) 172c is, for example, in the fully closed position to close the rear ventilation sub-outlet 1822c of the right half.

[0271] At this time, for example, internal recirculated air is introduced into the upper layer of the inlet of the second right half of the casing, and its airflow within the casing is as follows: For the upper airflow, the upper intake airflow (here, the internal recirculated air intake airflow) F1i_c enters from the upper part of the inlet, first passing through the second airflow processing unit 130 (evaporator). Subsequently, the upper intake airflow F1i_c is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120, enters the fifth space V5, and directly enters the first space sub-region V1c (e.g., from the left side of the first mixing damper 310c) from the left side of the first mixing damper 310c. Figure 23B (The airflow direction is shown by dashed lines). The second airflow branch of the upper intake airflow F1i_c will pass through the first airflow processing unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space sub-region V3c through the first airflow processing unit 120, and enter the first space sub-region V1c via the right side of the first mixing damper 310c (as shown by dashed lines). Figure 23B (The airflow direction is shown in the dotted line). Subsequently, in the first spatial sub-region V1c, the two airflow branches will mix and form the upper output airflow (here, the internal recirculation air output airflow) F1o_c. At this time, the first sub-damper 170c, which is in the first position, will engage with the first partition and guide the upper output airflow F1o_c in the first spatial sub-region V1c to flow out through the right half of the rear foot outlet 162c.

[0272] For the lower-level airflow, in the current Figure 23B In the illustrated scenario, for example, the lower-level intake airflow may not be introduced. In this case, the second sub-damper 171c is, for example, in a completely closed state to block the first sub-section V2c-1 and the second sub-section V2c-2 of the second space. The lower-level intake airflow will not enter the second sub-section V2c-2 of the second space, nor will it be output through the demisting outlet 181c. However, it should be understood that, depending on the actual situation, fresh air can also be introduced as the lower-level intake airflow. In this case, the second sub-damper 171c can also be configured, for example, to be in a closed state. Figure 21B The opening position shown is configured to engage with the inner wall of the housing and guide the lower intake airflow through the demister outlet 181c.

[0273] Based on this, in foot-blowing mode, the division of the first and second space sub-zones is achieved through the cooperation of the first sub-air damper and the first partition in each first space sub-zone, and the upper internal circulating air is guided to be output through the corresponding front / rear foot sub-outlets to achieve the function of blowing feet with internal circulating air. On the other hand, depending on the actual situation, the defogging sub-outlet can be selectively opened, and through the cooperation of the second sub-air damper in each second space sub-zone and the inner wall, the lower fresh air can be used to achieve the defogging function.

[0274] Ventilation mode

[0275] Figure 24A A cross-sectional view of the first right half 1131 of a heating, ventilation and / or air conditioning unit 100' is shown, wherein the heating, ventilation and / or air conditioning unit 100' is in ventilation mode; Figure 24B A cross-sectional view of the second right half 1132 of a heating, ventilation and / or air conditioning unit 100' is shown, wherein the heating, ventilation and / or air conditioning unit 100' is in ventilation mode.

[0276] Reference Figure 24A When the heating, ventilation, and / or air conditioning unit 100' is in ventilation mode, the first sub-damper 170d in the first right half 1131 is configured in the second position to completely close the front air outlet 161d of the right half. The demisting sub-damper 191d will be in the fully closed position to completely close the demisting outlet 181d, and the front ventilation sub-damper 1921d will be open. The specific opening position can be adjusted according to actual needs to allow the outlet to open at the desired degree.

[0277] At this time, fresh air is introduced into both the upper and lower layers of the inlet of the first right half of the casing, and the airflow within the casing is as follows: For the upper airflow, the upper intake airflow (here, the internal recirculation air intake airflow) F1i_d enters from the upper part of the inlet, first passes through the second airflow processing unit 130 (evaporator), and then the upper intake airflow F1i_d is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120, enters the fifth space V5, and directly enters the first space sub-region V1d (e.g., from the left side of the first mixing damper 310d) from the fifth space V5. Figure 24A (The airflow direction is shown by dashed lines). The second airflow branch of the upper intake airflow F1i_d will pass through the first airflow processing unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space sub-region V3d through the first airflow processing unit 120, and enter the first space sub-region V1d via the right side of the first mixing damper 310d (as shown in the image). Figure 24A (The airflow direction is shown by the dotted line in the middle). In the first spatial sub-region V1d, the two airflow branches will mix and form the upper output airflow.

[0278] For the lower airflow, when fresh air is introduced, the lower air intake airflow (here, the fresh air intake airflow) F2i_d enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower air intake airflow F2i_d is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120 and enters the sixth space V6, directly entering the second space sub-region V2d from the right side of the second mixing damper 320d. Figure 24A(The airflow direction is shown by dashed lines). The second airflow branch of the lower intake airflow F2i_d will pass through the first airflow processing unit (heater) 120, specifically, it will enter the sixth space V6, then enter the fourth space sub-region V4d through the first airflow processing unit 120, and finally enter the second space sub-region V2d from the left side of the second mixing damper 320d (as shown by dashed lines). Figure 24A (The airflow direction is shown by dotted lines in the diagram). In the second spatial sub-region V2d, the two airflow branches will mix and form the lower-level output airflow.

[0279] At this time, the first sub-damper 170d in the first position will engage with the first partition and guide the upper output airflow in the first space sub-region V1d and the lower output airflow in the second space sub-region V2d to form the output airflow Fo_d, and the output airflow Fo_d flows out through the right half front ventilation sub-outlet 1821d.

[0280] Reference Figure 24B When the heating, ventilation, and / or air conditioning unit 100' is in ventilation mode, the first sub-damper 170c in the second right half 1132 is configured in the second position to completely close the rear air outlet 162c of the right half. The demisting sub-damper 191c will be in the fully closed position to completely close the demisting outlet 181c, and the third sub-damper (here, the front ventilation sub-damper) 172c is, for example, in the open position. The specific opening position can be adjusted according to actual needs so that the rear ventilation outlet 1822c of the right half is opened to the desired degree.

[0281] At this time, fresh air is introduced into the upper and lower layers of the inlet of the second right half of the casing, and the airflow within the casing is as follows: For the upper airflow, the upper intake airflow (here, the fresh air intake airflow) F1i_c enters from the upper part of the inlet, first passing through the second airflow processing unit 130 (evaporator). Then, the upper intake airflow F1i_c is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120, enters the fifth space V5, and directly enters the first space sub-region V1c (e.g., from the left side of the first mixing damper 310c) from the left side of the first mixing damper 310c. Figure 24B (The airflow direction is shown by dashed lines). The second airflow branch of the upper intake airflow F1i_c will pass through the first airflow processing unit (heater) 120, specifically, it will enter the fifth space V5, and then enter the third space sub-region V3c through the first airflow processing unit 120, and enter the first space sub-region V1c via the right side of the first mixing damper 310c (as shown by dashed lines). Figure 24B (The airflow direction is shown by the dotted line). Subsequently, in the first spatial sub-region V1c, the two airflow branches will mix and form the upper output airflow (here, the fresh air output airflow) F1o_c.

[0282] For the lower airflow, when fresh air is introduced, the lower air intake airflow (here, the fresh air intake airflow) F2i_c enters, for example, from the lower part of the inlet. First, it is processed by the second airflow processing unit 130 (evaporator). Then, the lower air intake airflow F2i_c is divided into two airflow branches. The first airflow branch bypasses the first airflow processing unit 120 and enters the sixth space V6, directly from the right side of the second mixing damper 320c into the first sub-region V2c-1 of the second space. Figure 24B (The airflow direction is shown by dashed lines). The second airflow branch of the lower intake airflow F2i_c will pass through the first airflow processing unit (heater) 120, specifically, it will enter the sixth space V6, then enter the fourth space sub-zone V4c through the first airflow processing unit 120, and finally enter the second space first sub-zone V2c-1 from the left side of the second mixing damper 320c (as shown in the image). Figure 24B (The airflow direction is shown as a dotted line in the diagram). Subsequently, in the first sub-region V2c-1 of the second space, the two airflow branches will mix and form the lower output airflow F2o_c.

[0283] At this time, the second sub-damper 171c, which is in the fully closed position, will engage with the first partition and the lateral extension wall to separate the first sub-zone V2c-1 and the second sub-zone V2c-2 of the second space. On the one hand, the upper output airflow F1o_c in the first sub-zone V1c is guided to the second sub-zone V2c-2 of the second space and output through the right half front ventilation sub-outlet 1821c. On the other hand, the lower output airflow F2o_c is made to flow only in the first sub-zone V2c-1 of the second space and output through the right half rear ventilation sub-outlet 1822c.

[0284] Based on the above, in this application, in the ventilation mode, the corresponding air outlet is completely closed by the first sub-air damper in each first space sub-area, and each ventilation outlet is selectively opened by the third sub-air damper. The airflow is guided by the cooperation of the second sub-air damper and the first partition, so that, for example, the upper air intake airflow is output through the corresponding front ventilation outlet and the lower air intake airflow is output through the corresponding rear ventilation outlet. This is beneficial to achieve independent temperature control of each front ventilation port and rear ventilation port in the ventilation mode.
