Description

Panel body assembly, indoor unit and assembly method of indoor unit

[0001] This disclosure claims priority to a Chinese patent application filed with the Patent Office of China on September 6, 2023, with application number 202311147891.9 and invention name “A panel body assembly, indoor unit and assembly method of indoor unit”, the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure belongs to the technical field of air conditioning, and particularly relates to a panel body assembly, an indoor unit, and an assembly method of the indoor unit. Background Art

[0003] With the continuous improvement of living standards and the increasing diversification of people's needs, people's demands for quality of life are also increasing, and their expectations for the services that products can provide are becoming more stringent. In the air conditioning industry, customers require more than just basic cooling and heating functions; they often also demand additional attributes to enhance the product experience, such as humidification, air purification, and self-cleaning functions. Adding these features often requires integrating features from other products into the air conditioner. Take self-cleaning filters as an example. Self-cleaning filter air conditioners essentially integrate cleaning brushes and dust collection devices into the air conditioner. Integrating these features with existing air conditioners is a key area of ​​continuous improvement and breakthrough in the development of these new products. Existing self-cleaning filter air conditioners use a one-piece design, requiring modifications to components such as the bottom housing to accommodate the self-cleaning features. This results in high development costs and limited component commonality.

[0004] At the same time, since this type of new product has more parts and a more complex structure, part quality problems or assembly problems are inevitable during assembly on the production line. Most existing self-cleaning products set the various components of the cleaning device separately on different parts of the indoor unit. Therefore, the function of the cleaning device can only be tested after the indoor unit is assembled. If a problem is found during the test, the indoor unit needs to be returned for repair as a whole, resulting in higher repair costs and difficulty.

[0058] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0059] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0060] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0061] Unless otherwise specified, the relative arrangement of components and steps, numerical expressions, and values ​​described in these embodiments do not limit the scope of the present disclosure. It should be understood that, for ease of description, the structures, proportions, and sizes shown in the accompanying drawings are intended solely to facilitate understanding and interpretation by those skilled in the art, and are not intended to limit the scope of the present disclosure. Any structural modifications, changes in proportional relationships, or adjustments in size, without affecting the efficacy and objectives of the present disclosure, should still fall within the scope of the technical content disclosed herein. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but, where appropriate, should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely illustrative and not limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following figures; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0062] In the description of the present disclosure, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present disclosure and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present disclosure; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0063] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0064] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this disclosure.

[0065] With reference to Figures 1-19, according to an embodiment of the present disclosure, a panel assembly 100 is provided. The panel assembly 100 includes a panel body 200 and a filter device 300. The filter device 300 includes a filter, a control panel 3, a drive mechanism, and a cleaning assembly. The filter is configured to filter the intake air of the indoor unit. The control panel 3 is configured to control the drive mechanism to drive at least one of the filter and the cleaning assembly to move, causing the cleaning assembly to clean the filter.

[0066] Among them, the filter, control panel 3, drive mechanism and cleaning component are all arranged on the panel body 200, so as to be assembled with the body of the indoor unit through the panel body 200. It should be noted here that: "assembly" here only refers to the assembly on the mechanical structure, and does not include the connection of the filter, control panel 3, drive mechanism or cleaning component to the body of the indoor unit that is configured to transmit data signals or to be configured to meet power supply requirements. For example, the filter, control panel 3, drive mechanism or cleaning component can be connected to the body of the indoor unit through a data cable or a wireless communication module to meet the need of signal transmission. Or the filter, control panel 3, drive mechanism or cleaning component can be connected to the power supply or the electrical box 7 of the indoor unit body through a power cord to meet the need of power supply, so that the electrical box 7 is powered by the power cord.

[0067] Compared with the related art in which the various components of the filter device 300 are respectively arranged on different parts of the indoor unit, resulting in the filter device 300 being tested only after the indoor unit is assembled, in the above example, the present disclosure integrates all the components of the filter device 300 on the panel body 200. During the pre-installation stage of the indoor unit, the filter device 300 can be independently tested after the assembly of the filter device 300 and the panel body 200 is completed. If a problem occurs with the filter device 300 during the test in the pre-installation stage, it can be repaired in time. Compared with the related art in which the entire machine is returned for repair, the present disclosure only needs to return the panel body assembly 100 for repair, which can greatly reduce the cost and difficulty of repair.

[0068] It should be noted here that the specific structure of the driving mechanism being controlled to drive at least one of the filter screen and the cleaning component to move so that the cleaning component cleans the filter screen is related technology and will not be described in detail here.

[0069] In a specific application example, the aforementioned control board 3 is a low-voltage board, which is configured to be connected to a power supply and can control the driving mechanism to drive at least one of the filter and the cleaning component to move according to the remote control signal of the indoor unit.

[0070] Among them, in the related art, the control module that controls the driving mechanism to drive the movement of at least one of the filter and the cleaning component according to the remote control signal of the indoor unit is generally integrated in the electrical box 7 of the indoor unit, while the present disclosure independently sets the control module in the electrical box 7 on the control board 3. During testing, it is only necessary to power on the control board 3 and then send a signal to the control board 3 through the remote control of the indoor unit to operate the filter device 300 for testing.

[0071] To install the filter, control panel 3, drive mechanism, and cleaning assembly on the panel body 200, these components can be installed in the following manner. In a specific application example, to install the filter, as shown in Figures 1 to 3, when the drive mechanism is configured to control the movement of the filter, the panel body 200 can be provided with a limiting track, and the filter can be movably mounted on the limiting track so as to be driven to move along the limiting track. The filter is mounted on the panel body 200 via the limiting track. To install the control panel 3, the panel body 200 can be provided with a clamping portion, which clamps the panel body 200 to the control panel 3. As shown in Figure 2, the clamping portion can include a spring catch 101 and a limiting catch 102. The panel body 200 is clamped to the control panel 3 via the spring catch 101, and the panel body 200 is restrained in position by the limiting catch 102. During installation, the control panel 3 can be directly placed into the control panel mounting position by simply placing it in the control panel mounting position and then pressing down on it. In order to install the driving mechanism, the driving mechanism may include a motor to drive at least one of the filter and the cleaning component to move through the motor. As shown in Figure 1, a motor bracket 6 may be provided on the panel body 200 to power the motor installation through the motor bracket 6. In order to install the cleaning component, the cleaning component may include a dust box 5 and a cleaning member arranged in the dust box 5, and the cleaning component cleans the filter through the cleaning member. A fixed plate 4 and a limiting block 108 are provided on the panel body 200, and the cleaning component is installed on the fixed plate 4 through the dust box 5. The limiting block 108 is configured to limit the dust box 5. In addition to limiting the dust box 5, the limiting block 108 also reserves a limited space for the dust box 5 to facilitate the installation of the dust box 5.

[0072] In the above example, by improving the structure of the panel body 200, the filter, control panel 3, drive mechanism and cleaning assembly can be integrated on the panel body 200 to form an independent panel body assembly 100, so as to facilitate independent testing of the filter device during the pre-installation stage.

[0073] As shown in Figure 1, the aforementioned panel body 200 may include an outer cover 2 and a panel body bracket 1. The panel body bracket 1 is detachably connected to the outer cover 2, and the panel body bracket 1 can be replaced with different types to cooperate with the outer cover 2 to be assembled on the body of the indoor unit of the corresponding model.

[0074] In the above example, different types of panel body brackets 1 can share the same outer cover 2, and different types of panel body brackets 1 can be connected to the outer cover 2 to form different types of panel bodies 200. For different models of indoor units, it is only necessary to replace the panel body bracket 1 on the panel body assembly 100 with the corresponding type and keep the outer cover 2 unchanged to achieve adaptation. This can greatly improve the portability of the panel body assembly 100 and reduce the R&D cycle and cost of new products.

[0075] In a specific application example, as shown in FIG1 , the aforementioned outer cover 2 may include an outer cover base 21 and a filter support 22 provided on the outer cover base 21 , and the filter support 22 is configured to provide support for the filter.

[0076] To facilitate replacement of the panel support 1, the components of the filter device 300 mounted on the panel support 1 should be removable. In a specific application example, the panel 200 is provided with a filter and cleaning assembly mounted via the outer cover 2. The panel 200 is provided with a control panel 3 and a drive mechanism mounted via the panel support 1, and both the control panel 3 and the drive mechanism are removable.

[0077] In order to install the filter and the cleaning assembly on the outer cover 2 of the panel body 200, as shown in Figures 1 to 3, when the panel body 200 is provided with a limiting track and the filter is used to be movably set on the limiting track, the limiting track is used to be set on the outer cover 2 to be connected to the panel body 200 through the outer cover 2. When the cleaning assembly includes a dust box 5 and a cleaning member set in the dust box 5, and the panel body 200 is provided with a fixing plate 4 and a limiting block 108, and the cleaning assembly is installed on the fixing plate 4 through the dust box 5, the fixing plate 4 is used to be set on the outer cover 2 to be connected to the panel body 200 through the outer cover 2. Among them, the limiting block 108 is used to be set on the panel body bracket 1 to be connected to the panel body 200 through the panel body bracket 1. The limiting block 108 can limit the dust box 5, making it easier to install the dust box 5.

[0078] In order to detachably mount the control board 3 and the drive mechanism on the panel body bracket 1, when the panel body 200 is provided with a snap-fitting portion and is snap-fitted to the control board 3 via the snap-fitting portion, the snap-fitting portion is configured to be disposed on the panel body bracket 1 so as to be connected to the panel body 200 via the panel body bracket 1. The control board 3 is detachably connected to the panel body bracket 1 via the snap-fitting portion. When the drive mechanism includes a motor and the panel body 200 is provided with a motor bracket 6, the motor bracket 6 is configured to be detachably mounted on the panel body bracket 1 so as to be connected to the panel body 200 via the panel body bracket 1. The motor is configured to be disposed on the motor bracket 6 and to be detachably connected to the panel body bracket 1 via the motor bracket 6.

[0079] The detachable connection of the motor bracket 6 can be achieved in the following manner: one of the motor bracket 6 and the panel bracket 1 can be provided with a first fixing buckle groove, and the other can be provided with a first fixing buckle. The first fixing buckle is configured to be snapped into the first fixing buckle groove to connect the motor bracket 6 and the panel bracket 1.

[0080] In some embodiments, when the driving mechanism includes a motor, the panel body 200 is provided with a motor bracket 6, and the motor bracket 6 is configured to be detachably mounted on the panel body bracket 1 so as to be connected to the panel body 200 via the panel body bracket 1, the panel body bracket 1 may further be provided with a support crossbeam 106 configured to support the motor bracket 6. The support crossbeam 106 is in a grid shape and has an arc-shaped groove 1061 configured to accommodate the motor.

[0081] In the above example, the supporting cross frame 106 is configured to provide support for the motor bracket 6 , while also playing the role of strengthening the panel body bracket 1 and reserving space for the installation of the motor.

[0082] To achieve a removable connection between the outer cover 2 and the panel support 1, as shown in Figures 3 and 7, one of the outer cover 2 and the panel support 1 is provided with a tab 203, and the other is provided with a tab 109. As shown in Figure 11, the tab 109 is configured to be inserted into the tab 203 to connect the outer cover 2 and the panel support 1. The tab 109 serves as a guide and limiter, facilitating the installation of the panel support 1. A second fixing tab 201 is also provided on one of the outer cover 2 and the panel support 1, and a second fixing tab groove 107 is provided on the other. When the tab 109 is inserted into the tab 203, the panel support 1 can be rotated within the tab 203 via the tab 109. When the tab 109 is rotated to the first position, the second fixing tab 201 is engaged with the second fixing tab groove 107 (as shown in Figure 14), and when the tab 109 is rotated to the second position, the second fixing tab 201 is released from the second fixing tab groove 107.

[0083] The inserting buckle 203 , inserting piece 109 , second fixing buckle 201 and second fixing buckle groove 107 provided on both the panel body bracket 1 and the outer cover 2 can ensure the fixation and installation of the panel body bracket 1 and the outer cover 2 .

[0084] Specifically, during installation, as shown in Figures 9 to 11, the first step is to insert the insert 109 on the panel body bracket 1 into the insert buckle 203. As shown in Figures 12 to 14, the second step is to press the panel body bracket 1. A click sound indicates that the second fixing buckle 201 is in place with the second fixing buckle groove 107. Then, the screw can be directly tightened. When the panel body bracket 1 is pressed downward, it will be blocked by the second fixing buckle groove 107. Under the action of the force, the panel body bracket 1 will deform to a certain extent, which will cause the second fixing buckle 201 to enter the fixing buckle groove, resulting in a click sound. This design ensures installation reliability and improves installation efficiency. Because the panel body bracket 1 needs to support the motor bracket 6 and other structures, it will produce a certain amount of deformation. Therefore, the design of the second fixing buckle 201 and the second fixing buckle groove 107 requires that the second fixing buckle 201 and the second fixing buckle groove 107 have an interference fit of 1 to 3 mm to ensure the effective fastening of the second fixing buckle 201 and the second fixing buckle groove 107.

[0085] The aforementioned panel body bracket 1 is provided with a first detachable connecting portion, and / or the outer cover 2 is provided with a second detachable connecting portion. The panel body 200 is detachably connected to the body of the indoor unit via the first detachable connecting portion and / or the second detachable connecting portion. In some embodiments, the panel body bracket 1 is provided with a first detachable connecting portion, and the outer cover 2 is provided with a second detachable connecting portion, and the panel body 200 is detachably connected to the body of the indoor unit via the first detachable connecting portion and the second detachable connecting portion. In this way, when the panel body 200 is damaged, it can be removed from the body of the indoor unit in a timely manner for repair or replacement, thereby reducing repair costs.

[0086] The structures of the first detachable connection parts on the aforementioned different types of panel body brackets 1 are the same, and the positions of the first detachable connection parts can be the same or different, thereby saving the design cost of the first detachable connection.

[0087] Because the indoor unit body is composed of multiple parts, including an electrical box 7 and a bottom housing 8, the indoor unit body can include, among other things, an electrical box 7 and a bottom housing 8. To enable the panel body 200 to be detachably connected to the indoor unit body, as shown in FIG2 , the aforementioned first detachable connection portion can include a first screw column 104 and a retaining pin 105. As shown in FIG4 through FIG6 , the first screw column 104 is configured to connect via a first screw member 10 to a screw hole 71 on the electrical box 7 of the indoor unit body of the corresponding model. The retaining pin 105 is configured to engage with a retaining slot 72 on the electrical box 7.

[0088] It should be noted that the retaining groove 72 on the electrical box 7 and the retaining pin 105 on the panel body bracket 1 are clearance-matched, with the clearance between each side being controllable between 0.3 and 0.6 mm. In some embodiments, the clearance between the retaining groove 72 and the retaining pin 105 is 0.45 mm. The fit between the retaining groove 72 and the retaining pin 105 is merely configured for approximate positioning, while also preventing the electrical box 7 from tilting to the left or right, which would increase the workload of production line workers and thus improve production efficiency.

[0089] As shown in Figure 2, the first detachable connection part also includes a screw hole 103. As shown in Figures 15 to 17, the screw hole 103 is configured to be connected to the second screw column 801 on the bottom shell 8 of the indoor unit body of the corresponding model through the second screw member 11. In order to improve the connection stability between the panel body bracket 1 and the bottom shell 8, in some embodiments, the number of screw holes 103 can be more than two, and in some embodiments, the number of screw holes 103 is 3. It should be noted here that: another screw hole 202 is provided on the above-mentioned outer cover 2, and the second screw member 11 is configured to pass through the screw hole 103 and be connected to the other screw hole 103, so as to fix the outer cover 2 and the panel body bracket 1 at the same time.

[0090] In a specific application example, as shown in Figures 7 and 8, the aforementioned second detachable connection portion may include a limiting square hole 204. As shown in Figures 18 and 19, the limiting square hole 204 is configured to be plugged into and engaged with a buckle tongue 802 on the bottom shell 8 of the indoor unit body of the corresponding model.

[0092] As shown in FIG8 and FIG15, the aforementioned second detachable connection portion may further include a latch 205, which is configured to be plugged into and fitted with a limiting hole 803 on the bottom shell 8 of the indoor unit body of the corresponding model.

[0093] It should be noted here that: a limiting hole 803 can be provided on the bottom shell 8 of the indoor unit body of each model, and a pin 205 can be provided on the outer cover 2, so that the outer cover 2 can be adapted to the bottom shell 8 of the indoor unit body of each model, thereby further improving the versatility of the outer cover 2 and reducing the product development cost.

[0094] The gap between the latch 205 and the stop hole 803 is between 0.2 and 0.35 mm. In some embodiments, the gap between the latch 205 and the stop hole 803 is 0.275 mm. The gap between the latch 205 and the stop hole 803 can be adjusted appropriately based on the model. If the gap between the latch 205 and the stop hole 803 is too small, it can easily cause installation difficulties and affect production. If the gap is too large, it can cause tripping problems.

[0095] The latch 205 and the limiting square hole 204 on the outer cover 2 can be both set at the lower edge of the outer cover 2. The latch 205 and the limiting square hole 204 respectively cooperate with the limiting hole 803 and the buckle tongue 802 on the shell to ensure that the panel body 200 is matched with the lower edge of the bottom shell 8.

[0096] It should be noted here that: the bottom shell 8 has conventional structural features, and is provided with a buckle tongue 802, a limiting hole 803, a second screw column 801, etc., and the bottom shell 8 can also cooperate normally with the ordinary panel body 200. Among them, the buckle tongue 802 on the bottom shell 8 is set to cooperate with the limiting square hole 204 on the outer cover 2, the limiting hole 803 on the bottom shell 8 is set to cooperate with the pin 205 on the outer cover 2, and the second screw column 801 on the bottom shell 8 is set to cooperate with the screw hole 103 on the panel body bracket 1, so that the two can be fixed by screws. Among them, the cooperation structure of the bottom shell 8 and the panel body assembly 100 of the present disclosure is completely consistent with the cooperation of the ordinary panel body 200, which also means that the ordinary panel body 200 can be directly replaced with the panel body assembly 100.

[0097] After the panel body assembly 100 is mated with the bottom shell 8, the front edge of the panel body bracket 1 has three screw holes 103, and the panel body bracket 1 is fixed to the bottom shell 8 through these three screw holes 103. The panel body assembly 100 is mated with the bottom shell 8 through the latch 205 and the limiting square hole 204 at the rear lower part of the outer cover 2. When installing the panel body assembly 100, it is only necessary to first directly interlock the latch 205 at the rear lower part of the outer cover 2 of the panel body 200 with the bottom shell 8, then press the panel body 200 forward to directly engage it, and then drive screws into the screw holes 103 at the front edge of the panel body bracket 1 to completely fix the panel body assembly 100 to the bottom shell 8.

[0098] An embodiment of the present disclosure further provides an indoor unit, which includes a machine body and any one of the above-mentioned panel body components 100. The panel body component 100 is connected to the machine body through the panel body 200.

During the pre-installation stage of the indoor unit, the filter device 300 can be independently tested after the assembly of the filter device 300 and the panel body 200 is completed. If a problem occurs with the filter device 300 during the test in the pre-installation stage, it can be repaired in time. Compared with the related art of returning the whole machine for repair, the present disclosure only needs to return the panel body component 100 for repair, which can greatly reduce the cost and difficulty of repair.

[0099] In a specific application example, when the control board 3 is a weak current board, the body of the indoor unit has an electrical box 7, which contains a strong current board. The control board 3 is connected to the strong current board through a cable to supply power through the strong current board.

[0100] In the above example, the control panel 3 can be powered by the electrical box 7 of the indoor unit itself, so there is no need to design an additional electrical box 7 component for the control panel 3 to provide power, thus saving component development costs.

[0101] It should be noted that the electrical box 7 can control the movement of the air guide plate of the indoor unit. The electrical box 7 can be a related art electrical box without a filter self-cleaning function. It only needs to be connected to the control board 3 via a cable so that the electrical box 7 can supply power to the control board 3.

[0102] The embodiment of the present disclosure further provides an assembly method of the indoor unit, which comprises the following steps:

[0103] Step S1 : Assembling the filter device 300 onto the panel body 200 to form the panel body assembly 100 .

[0104] Step S2: Assemble the panel body assembly 100 with the body of the indoor unit, and assemble the panel body assembly 100 with the body through the panel body 200.

[0105] In the above example, during the pre-installation stage of the indoor unit, since all the components constituting the filter device 300 can be assembled onto the panel body 200 to form the panel body assembly 100, the filter device 300 can be independently tested after the assembly of the filter device 300 and the panel body 200 is completed. If a problem occurs with the filter device 300 during the test in the pre-installation stage, it can be repaired in time. Compared with the related art of returning the entire machine for repair, the present disclosure only requires returning the panel body assembly 100 for repair, which can greatly reduce the cost and difficulty of repair.
