Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and in particular to an air conditioner and its control method. Background Technology

[0002] In related technologies, the humidification module of an air conditioner is generally located at the bottom of the cross-flow duct. The humidification component of the humidification module needs to be replaced after a period of use, and the water tank of the humidification module also needs to be filled or replaced. The disassembly and assembly of the water tank and the humidification component need to be performed from the front. Therefore, the air conditioner panel needs to be set as a split upper and lower panel. The humidification component can be replaced and the water tank can be filled after opening the lower panel.

[0003] However, with separate upper and lower panels, the lower panel needs to be opened first when replacing the humidifier or filling the water tank, which is cumbersome, and the separate upper and lower panels are not aesthetically pleasing. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an air conditioner that is more aesthetically pleasing, easier and more convenient to replace the humidifier and fill the water tank, and has a larger water storage capacity.

[0005] This application further proposes a control method for the aforementioned air conditioner.

[0006] An air conditioner according to a first aspect of this application includes: a body, an air handling module, a door opening and closing assembly, and a drive assembly. The front surface of the body has an air outlet, and the body has a receiving space located on one side of the air outlet along its length. The air handling module includes a base and a water tank. The base is disposed within the receiving space, and the water tank is detachably disposed on the base. The door opening and closing assembly is movably disposed on the body to switch between at least a first state and a second state. In the first state, the door opening and closing assembly blocks the air outlet and the air handling module. In the second state, the air outlet and at least a portion of the air handling module are exposed to allow for the removal of the water tank. The drive assembly is disposed on the body and connected to the door opening and closing assembly to drive the door opening and closing assembly to move.

[0007] According to the embodiments of this application, the air conditioner, by setting a door opening and closing assembly and a drive assembly for driving the door opening and closing assembly, allows the door opening and closing assembly to selectively block the air outlet and the air handling module. Furthermore, in a second state where the opening width of the door opening and closing assembly is greater than in the first state, the water tank can be disassembled. On one hand, the door opening and closing assembly is constructed as an "integrated panel," which improves the aesthetics of the air conditioner. On the other hand, not only can the door opening and closing assembly achieve automatic opening and closing, improving the convenience of water tank disassembly, but the width of the water tank can also be set to be larger, increasing the water storage capacity and reducing the water filling frequency, thus improving the user experience.

[0008] In some embodiments, the base includes a fixed seat and a bracket, the fixed seat is fixed to the receiving space, the bracket is retractably engaged with the fixed seat, the bracket is provided with a water tank, and the water tank is detachably disposed on the bracket.

[0009] According to some embodiments of this application, the top of the bracket is slidably engaged with the fixed seat via a cantilever, and the water tank is located at the lower part of the bracket.

[0010] Furthermore, the cantilever is provided with a clearance space, a portion of the water tank is supported on the cantilever, and the remaining portion of the water tank is placed in the water tank through the clearance space.

[0011] In some embodiments, the bracket includes: a base, the base having the water tank; a front panel, the front panel being disposed on the front side of the base and having an air inlet, the humidifier and the water tank being respectively located on the rear side of the front panel, and in the second state, the front panel being exposed to pull out the bracket.

[0012] According to some embodiments of this application, the door opening and closing assembly includes two doors that can move toward or away from each other to switch between at least the first state and the second state.

[0013] In some embodiments, the front surface of the housing is provided with a rearwardly recessed air outlet space, the air outlet is disposed in the air outlet space, and the switch door is movably disposed in the air outlet space. In the first state, the two switch doors are combined, and the switch door assembly in the combined state is respectively spaced apart from both sides of the air outlet space.

[0014] According to some embodiments of this application, the air conditioner has a first air outlet mode in which the door opening and closing assembly completely avoids the air outlet, and the door opening and closing assembly blocks a portion of the air handling module to prevent the water tank from being disassembled.

[0015] Furthermore, the air conditioner also includes: a first limiter and a second limiter, and a water-filling trigger button. The first limiter is electrically connected to the control module of the air conditioner. The second limiter moves synchronously with the door opening and closing assembly. When the first limiter is open and the second limiter is detected, the control module controls the drive assembly to stop running to position the door opening and closing assembly. The water-filling trigger button is electrically connected to the control module. When the first limiter is open and the water-filling trigger button is triggered to issue a water-filling command, the control module controls the first limiter to stop working. When the water-filling trigger button is triggered to issue a water-filling command, the control module receives a signal to control the door opening and closing assembly to switch to the second state through the drive assembly.

[0016] Furthermore, the water-adding trigger key is located on the body of the device, and the water-adding trigger key is configured to issue a water-adding command when it is triggered and lit.

[0017] Further, the drive assembly includes: a mounting box disposed on the body; a drive member mounted to the mounting box and electrically connected to the control module, wherein the first limiter is disposed on the mounting box; and a moving member connected to both the door opening / closing assembly and the drive member, wherein the drive member drives the moving member to move in order to move the door opening / closing assembly, wherein the second limiter is disposed on the moving member.

[0018] Furthermore, the first limiter is a Hall sensor, and the second limiter is a metal part or a magnetic part.

[0019] According to a control method for an air conditioner according to a second aspect of this application, the air conditioner includes a body, a water tank, two doors, a first limiter, and a second limiter. The water tank is detachably disposed on the body and located on one side of the air outlet. The control method includes the following steps: receiving a central air outlet command; controlling the two doors to move away from each other until the first limiter senses the second limiter, and controlling the two doors to stop moving; receiving a water filling command, controlling the first limiter to stop operating and controlling the two doors to continue moving away from each other until a set position is established to define a disassembly space, and disassembling the water tank from the disassembly space; receiving a water filling completion command, controlling the first limiter to operate and controlling the two doors to move closer to each other until the first limiter senses the second limiter, and controlling the two doors to stop moving.

[0020] Furthermore, the device body is equipped with a water-filling trigger button. When the water-filling trigger button is triggered and lit, a water-filling command is issued; when the water-filling trigger button is triggered again and lit, a water-filling completion command is issued.

[0043] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] The following is for reference. Figures 1-11 An air conditioner 100 and a control method according to an embodiment of the present invention are described.

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, the air conditioner 100 according to the first aspect embodiment of this application includes: a body 10, an air handling module 20, a door opening and closing assembly 30, and a drive assembly 40.

[0048] Among them, such as Figure 4 and Figure 5 As shown, the front surface of the unit 10 is provided with an air outlet b, and the unit 10 has a receiving space a inside. The receiving space a is located on one side of the length direction of the air outlet b. The air conditioner 100 is constructed as a vertical air conditioner 100. The front surface of the unit 10 can be selectively opened to form an air outlet b, while the receiving space a is defined inside the unit 10. The air handling module 20 and components such as the evaporator used for heat exchange are distributed sequentially in the vertical direction in the receiving space a. When the air conditioner 100 is performing heat exchange (cooling or heating) operation, the heat exchange airflow is discharged through the air outlet b on the front side of the unit 10 to achieve cooling or heating of the indoor space. The air handling air outlet b of the air handling module 20 is located on the side of the unit 10. The airflow after the air handling module 20 performs air operations such as fresh air mode, humidification mode, and internal circulation mode (indoor air purification) is discharged through the side air outlet.

[0049] like Figure 6 and Figure 10 As shown, the air handling module 20 includes a base 21 and a water tank 22. The base 21 is located within the accommodating space a, and the water tank 22 is detachably mounted on the base 21. During daily use, the water tank 22 needs to be filled and replaced with water. The water tank 22 is detachably mounted on the base 21 so that when water needs to be added or replaced, the water tank 22 can be moved out of the accommodating space a, thereby improving the convenience of adding and replacing water in the water tank 22.

[0050] Furthermore, a door opening and closing assembly 30 is provided on the front side of the body 10. The door opening and closing assembly 30 is movably provided on the body 10 to switch between at least a first state and a second state. In the first state, the door opening and closing assembly 30 blocks the air outlet b and the air handling module 20. In the second state, the air outlet b and at least a portion of the air handling module 20 are exposed to allow for the removal of the water tank 22.

[0051] In other words, the door opening / closing assembly 30 is formed as a panel of the air conditioner 100, which can selectively block the air outlet b and the front of the air handling module 20 (i.e., the first state, see...). Figure 1 When water tank 22 needs to be replaced, switch to the second state (see...). Figure 3 In the second state, the air outlet b and at least part of the air handling module 20 are exposed, and the water tank 22 can be disassembled at this time.

[0052] Understandably, the door opening and closing assembly 30 can block the air outlet b and the air handling module 20. When the water tank 22 needs to be replaced, the door opening and closing assembly 30 can be switched to the second state. There is no need to set up separate upper and lower panels. The door opening and closing assembly 30 can be formed as an "integrated panel" on the front side of the air conditioner 100 body 10, which can improve the aesthetics of the air conditioner 100.

[0053] like Figure 4 and Figure 5 As shown, in the first state, the door opening and closing assembly 30 of this application blocks the air outlet b, but does not block the air outlet b. When the door opening and closing assembly 30 is in the first state, the air conditioner 100 can be in the off state or the on state.

[0054] Specifically, when the air conditioner 100 is in the off state and the door opening / closing assembly 30 is in the first state, the door opening / closing assembly 30 blocks the air outlet b, which can prevent dust and foreign objects from entering the air conditioner 100 through the air outlet b, improving the stability of the air conditioner 100 and enhancing its aesthetics when off. When the air conditioner 100 is in the on state and the door opening / closing assembly 30 is in the first state, a lateral air duct can be defined between the body 10 and the side of the door opening / closing assembly 30, enabling lateral airflow from the air conditioner 100. When the door opening / closing assembly 30 moves to the second state, the water tank 22 can be disassembled. There is also an intermediate state of the door opening / closing assembly 30 between the second and first states (see...). Figure 2 The intermediate state can be a dynamic process. In the intermediate state, the door opening and closing assembly 30 gradually opens until the opening width is consistent with the width of the air outlet b (the maximum intermediate opening width S2 in the intermediate state). This not only enables air outlet in the middle, but also enables control of the air volume of the air outlet in the middle.

[0055] More importantly, when the door opening assembly 30 is in the first state, the first opening width S1 of the door opening assembly 30 is zero, and the maximum intermediate opening width S2 in the intermediate state is the same as the width of the air outlet b. When the door opening assembly 30 is in the second state, the second opening width S3 of the door opening assembly 30 is greater than the width of the air outlet b, so that at least part of the air handling module 20 is exposed. At this time, the water tank 22 can be disassembled. Correspondingly, the width of the water tank 22 can be set to be greater than the width of the air outlet b and less than or equal to the second opening width S3 of the door opening assembly 30. This allows for the setting of a larger water tank 22 to increase the water storage capacity of the water tank 22, reduce the number of water fillings, and improve the user experience.

[0056] In other words, when the door opening assembly 30 moves to the point where the air outlet b is fully open, the water tank 22 cannot be disassembled. However, in the second state, when at least part of the air handling module 20 is exposed, the water tank 22 can be disassembled. At this time, the air outlet b is still open, and the air conditioner 100 can still perform cooling or heating operations. Disassembling the water tank 22 will not affect the heat exchange function of the air conditioner 100, thus achieving compatibility between the two.

[0057] It should be noted that the door opening and closing assembly 30 can be constructed as a folding door structure with one side fixed to the body 10 in the width direction and the other side able to move toward or away from the other side. The door opening and closing assembly 30 can also be constructed as a sliding door structure or a flip door structure. The width of the space of the body 10 opened by the door opening and closing assembly 30 is different in the first state and the second state.

[0058] like Figure 7 , Figure 8 and Figure 9 As shown, the drive assembly 40 is located on the body 10 and connected to the door opening and closing assembly 30 to drive the door opening and closing assembly 30 to move. The drive assembly 40 drives the door opening and closing assembly 30 to move relative to the body 10. When it is necessary to fill or change the water tank 22, the door opening and closing assembly 30 can be automatically switched to the second state. In the prior art, it is necessary to manually open the panel corresponding to the air handling module 20 to disassemble and install the water tank 22. This application does not require manual flipping of the panel structure, which can improve the convenience of filling the water tank 22.

[0059] It should be noted that when the door opening and closing assembly 30 is constructed as a folding door, the drive assembly 40 can be directly driven by a linear motor, or a rotary motor and a lead screw and nut mechanism can be used to achieve linear motion. When the door opening and closing assembly 30 is constructed as a sliding door structure, both doors 31 can be constructed as flip doors and opened and closed by a rotary motor. The two doors 31 can also be constructed as sliding doors, so that they can be directly driven by a linear motor, or a rotary motor and a lead screw and nut mechanism can be used to achieve linear motion.

[0060] According to the embodiment of this application, the air conditioner 100 is equipped with a door opening and closing assembly 30 and a drive assembly 40 for driving the door opening and closing assembly 30. The door opening and closing assembly 30 can selectively block the air outlet b and the air handling module 20. In a second state where the opening width of the door opening and closing assembly 30 is greater than that of the first state, the water tank 22 can be disassembled. On the one hand, the door opening and closing assembly 30 is constructed as an "integrated panel", which can improve the aesthetics of the air conditioner 100. On the other hand, not only can the door opening and closing assembly 30 realize automatic opening and closing, which can improve the convenience of disassembling the water tank 22, but the width of the water tank 22 can also be set to be larger, which can increase the water storage capacity of the water tank 22, reduce the water filling frequency of the water tank 22, and improve the user experience.

[0061] like Figure 6 As shown, in some embodiments, the base 21 includes a fixed seat 214 and a bracket 213. The fixed seat 214 is fixed to the accommodating space a, and the bracket 213 is retractably matched with the fixed seat 214. The bracket 213 is provided with a water tank 211, and the water tank 22 is detachably provided on the bracket 213.

[0062] Specifically, the base 21 is located within the accommodating space a. The base 21 is equipped with a water tank 211 and a humidifying element 212. The water tank 22 is detachably mounted on the base 21 to supply water to the water tank 211. The humidifying element 212 can draw water from the water tank 211 and use it to add an appropriate amount of air flowing through it. That is, the air handling module 20 can at least achieve the humidification function. The water tank 22 fills the water tank 211 with water, and the water in the water tank 211 can wet the humidifying element 212. The humidifier 212 can humidify the airflow passing through the air handling module 20 to humidify the air in the indoor space. The humidifier 212 is a consumable part and needs to be replaced, cleaned and maintained during daily use. The water tank 22 needs to be filled and changed. The water tank 22 is detachably mounted on the base 21 so that when water needs to be filled or changed, the water tank 22 can be moved out of the housing space a, which improves the convenience of filling and changing water in the water tank 22.

[0063] The mounting base 214 is disposed on the base 21 of the air treatment module 20 or at least a portion of the base 21 of the air treatment module 20 is formed as the mounting base 214. For example, the top or bottom of the base 21 of the air treatment module 20 forms a slide rail structure that slides with the bracket 213, and the front side of the base 21 of the air treatment module 20 is open to form a slot, into which the bracket 213 and the water tank 22 can be inserted, and pulled out of the slot and located outside the receiving space a, so as to realize the disassembly of the water tank 22.

[0064] The bracket 213 can be slidably mounted on the fixed base 214 via a sliding rail structure. The air inlet for the air handling module 20 to perform humidification is formed on the bracket 213. When the water tank 22 is assembled to the bracket 213 and the bracket 213 is inserted into the slot, in humidification mode, the humidifying airflow can enter the air handling module 20 through the air inlet and fully contact the humidifying element 212 to achieve air humidification. After humidification, the air is discharged through the air handling outlet b located on both sides of the body 10. The air inlet is a plurality of micropores arranged in an array on the bracket 213.

[0065] It is understandable that the bracket 213 and the fixed base 214 are slidably engaged, and the water tank 22 is detachably mounted on the bracket 213. The disassembly and removal of the water tank 22 is simpler and more convenient. At the same time, the humidifier 212 is mounted on the bracket 213, and after the bracket 213 is moved out of the receiving space a, the disassembly and replacement of the humidifier 212 mounted on the bracket 213 is also simpler and more convenient. The geometric dimensions of the humidifier 212 mounted on the bracket 213 can also be set to be larger, which can also improve the humidification efficiency.

[0066] Among them, such as Figure 6 As shown, an unlocking post can be installed on the water tank 211, and a press-stop valve that cooperates with the unlocking post can be installed on the water inlet of the water tank 22. When the water tank 22 is installed on the bracket 213, the unlocking post extends into the press-stop valve and continuously triggers the press-stop valve so that the water in the press-stop valve is discharged into the water tank 211, realizing circulating and stable water injection. At least part of the humidifying element 212 can be immersed in the water tank 211 so that the humidifying element 212 is wetted, thereby humidifying the indoor air through the humidifying element 212.

[0067] like Figure 6 As shown, according to some embodiments of this application, the top of the bracket 213 is slidably engaged with the fixed seat 214 via a cantilever 2131, and the water tank 211 is located at the lower part of the bracket 213.

[0068] Specifically, the cantilever 2131 and the water tank 211 are located at both ends of the bracket 213, and both the cantilever 2131 and the water tank 211 extend toward the air handling module 20. The cantilever 2131 and the fixed base 214 can be slidably engaged by a slide rail assembly (e.g., slide rail and slider). The cantilever 2131 and the water tank 211 can define the accommodating space a of the water tank 22, which can fix and limit the water tank 22 in the vertical direction, thereby improving the fixation stability of the water tank 22 and the working stability of the air handling module 20.

[0069] The slot on the base 21 of the air handling module 20 can be configured such that the opening gradually increases or decreases in the direction away from the door opening assembly 30. The corresponding water tank 211 and water tank 22 are provided with inclined surfaces that cooperate with the slot on the side facing the slot. On the one hand, the slot's narrowing or widening structure can cooperate with the inclined surface to achieve assembly guidance and improve the assembly convenience of the water tank 22 and bracket 213 on the base 21 of the air handling module 20. On the other hand, it can also limit the water tank 22 in the left and right directions to prevent the water tank 22 from moving around, thereby improving the working stability of the air handling module 20.

[0070] Furthermore, a clearance space is provided on the cantilever 2131, a portion of the water tank 22 is supported on the cantilever 2131, and the remaining portion of the water tank 22 is placed in the water tank 211 through the clearance space.

[0071] In other words, the water tank 22 may include a first part and a second part. The first part is attached to the cantilever 2131, the second part is connected to the first part, and the second part is provided with a clearance space. The lower end of the second part extends into the water tank 211 located at the lower part of the bracket 213, and the corresponding press-stop valve is formed on the lower end surface of the second part.

[0072] It should be noted that the humidifier 212 can draw water from the water tank 211 through the immersion effect. The upper cantilever 2131 is used to fix the first part of the water tank 22, while the second part of the water tank 22 is inserted into the bracket 213 from above and is arranged opposite to the base 21 of the air handling module 20 in the front-back or left-right direction, rather than in the vertical direction. This reduces the spatial limitation in the height direction of the air handling module 20. Compared with the technical solution where the base 21 of the air handling module 20 is inserted at the bottom, the volume of the water tank 22 in this application can be set to be larger, so that the water tank 22 has a larger water storage capacity, the humidification operation can last longer, and the number of fillings can be reduced to improve the user experience. A water injection hole can be provided on the area of ​​the water tank 22 corresponding to the press-stop valve. The press-stop valve is provided with internal or external threads so that the press-stop valve is constructed as a water tank cover. It can be selectively set on the water injection hole, which facilitates the maintenance of the press-stop valve. At the same time, the water tank 22 does not need to have too many openings, which can improve the sealing performance of the water tank 22.

[0073] In some embodiments, the bracket 213 includes a base 2133 and a front panel 2132. The base 2133 is provided with a water tank 211. The front panel 2132 is located on the front side of the base 2133 and is provided with an air inlet. The humidifier 212 and the water tank 22 are located on the rear side of the front panel 2132, respectively. In a second state, the front panel 2132 is exposed to pull out the bracket 213.

[0074] Specifically, the front panel 2132 has cantilever 2131 extending towards the same side as the front panel 2132 and base 2133 at both ends. A water tank 211 is located within the base 2133. An unlocking post is provided on the surface of the water tank 211 opposite to the water tank 22. A press-to-stop valve, cooperating with the unlocking post, is provided on the end face of the water tank 22 opposite to the water tank 211. When the water tank 22 is assembled onto the cantilever 2131, the unlocking post extends into the press-to-stop valve and unlocks it, allowing water in the water tank 22 to be injected into the water tank 2132 under gravity. Inside 11, the humidifier 212 can be constructed as a wet film, disposed on the front panel 2132 with its bottom end located inside the water tank 211, or disposed inside the water tank 211 and disposed opposite to the front panel 2132, so that the humidifier 212 can absorb water from the water tank 211, and an air inlet is provided on the front panel 2132. The air inlet can be constructed as an array of micropores formed on the front panel 2132, so that the humidifying airflow flows through the humidifier 212, and after humidification is completed, it is discharged from the air treatment outlet b located on the side of the body 10.

[0075] It should be noted that the width of the front panel 2132 is less than or equal to the second open width S3 of the door opening assembly 30 in the second state, and greater than the maximum middle open width S2. The width of the front panel 2132 is greater than or equal to the dimension of the water tank 22 in the left-right direction. On the one hand, this ensures that the front panel 2132 will not interfere with the door opening assembly 30 when the water tank 22 and / or the humidifier 212 are disassembled or installed, thus improving the ease of disassembly and installation. On the other hand, the front panel 2132 can completely cover the water tank 22, so that the water tank 22 will not be exposed in any state of the door opening assembly 30, which can also improve the aesthetics of the air handling module 20 and the air conditioner 100.

[0076] In some embodiments, a viewing slot can be provided on the front panel 2132, with liquid level markings on the viewing slot. The water tank 22 has a float that matches the liquid level markings, so that the user can observe the liquid level in the water tank 22. In other embodiments, a liquid level sensor can also be provided in the water tank 22. When the liquid level sensor detects that the water level in the water tank 22 is insufficient, a water-adding reminder will be issued so that the user can add water to the water tank 22 in a timely manner, thereby improving the working stability and user experience of the air handling module 20.

[0077] It is understood that the air handling module 20 has a handling fan 23, which is located downstream of the air inlet. The humidifying element 212, water tank 211, water tank 22, etc. are located in the humidification duct of the air handling module 20. The handling fan 23 generates a suction airflow so that the air in the indoor space enters the humidification duct from the air inlet. After fully contacting the humidifying element 212, it is discharged through the air handling outlet b located on both sides of the body 10. A humidity sensor 24 can also be installed in the air inlet area or the air outlet b area of ​​the handling fan 23. The humidity sensor 24 can detect the humidity of the air flowing out of the humidifying element 212 in real time, so as to adjust the speed of the handling fan 23 accordingly.

[0078] like Figure 7 , Figure 8 and Figure 9 As shown, according to some embodiments of this application, the door opening and closing assembly 30 includes two door opening and closing doors 31, which can move toward or away from each other to switch between at least a first state and a second state.

[0079] Specifically, the door opening and closing assembly 30 in this application embodiment is constructed as a double door structure, including two door opening and closing doors 31, and the two door opening and closing doors 31 are symmetrically arranged so as to move toward each other to a first state, or move away from each other to a second state, so as to realize the switching between the first state, the intermediate state and the second state.

[0080] When the air conditioner 100 switches to the off state or the side air outlet state, the two opening and closing doors 31 move towards each other to the first state. When switching from the off state or the side air outlet state to the center air outlet state, the two opening and closing doors 31 move away from each other to the middle state. The middle state is a dynamic process. The user can select an appropriate air outlet b opening degree (i.e., adjust the distance between the two opening and closing doors 31) according to the usage needs. When switching from the off state, or the side air outlet state, or the center air outlet state to the second state, the two opening and closing doors 31 move away from each other to reach the maximum distance between them, so that the front panel 2132 is fully exposed, and the water tank 22 and / or the humidifier 212 can be disassembled and assembled accordingly.

[0081] It should be noted that the two opening and closing doors 31 can be configured to move on the body 10 to achieve switching between the first state, the intermediate state and the second state, and the two opening and closing doors 31 can also be configured to swing on the body 10 to achieve switching between the first state, the intermediate state and the second state.

[0082] For example, the body 10 of the air conditioner 100 is rectangular. To improve aesthetics, the opening and closing doors 31 are all constructed as plate-shaped doors. A linear motor can be installed on the body 10 to drive the plate-shaped door to translate and realize the opening and closing of the opening and closing door assembly 30. A linear motor can also be installed on the body 10. A rotating shaft is provided on the side of the two opening and closing doors 31 that is away from each other so that the two opening and closing doors 31 rotate synchronously to realize the opening and closing.

[0083] like Figure 4 and Figure 5 As shown, in some embodiments, the front surface of the housing is provided with a rearwardly recessed air outlet space, the air outlet b is provided in the air outlet space, and the switch door 31 is movably provided in the air outlet space. In the first state, the two switch doors 31 are combined, and the switch door assembly 30 in the combined state is respectively spaced apart from the two sides of the air outlet space.

[0084] In other words, the curvature of the open air outlet is greater than the curvature of the two doors 31 when they are closed, so that in the first state, the closed door assembly 30 is separated from the sides of the air outlet. A guide grille can be provided on the body 10. In the first state, the guide grille is located on both sides of the door assembly 30, so that when the air conditioner 100 is in the side air outlet state, the side airflow can be guided by the guide grille located on both sides of the door assembly 30, thereby improving the uniformity of the side air outlet and allowing the air conditioner 100 to have at least two air outlet modes, namely center air outlet and side air outlet, to choose from, thereby improving the air outlet diversity of the air conditioner 100 and improving the user experience of the air conditioner 100.

[0085] It is understood that in some embodiments, air guide grilles are provided only on both sides of the door opening and closing assembly 30 to guide the lateral airflow when the air is vented laterally. In other embodiments, air guide grilles are provided on the rear and both sides of the door opening and closing assembly 30 so that the airflow can be guided through the air guide grilles when the air is vented laterally, vented in the middle, or vented in part of the lateral and part of the middle area at the same time, thereby improving the airflow effect.

[0086] The recessed air outlet space can accommodate components such as a cross-flow fan and an evaporator. The air outlet side of the cross-flow fan is connected to the air outlet b, or the air outlet b is formed on the fan casing of the cross-flow fan. The cross-flow fan, evaporator, and other components are stacked in the accommodating space a to achieve a compact configuration of the air conditioner 100. The cross-flow fan and the air handling module 20 are spaced apart in the vertical direction so that the front panel 2132 and the air outlet b are spaced apart in the vertical direction. This ensures that the heat exchange operation and air handling operation of the air conditioner 100 do not interfere with each other, thereby improving the working stability of the air conditioner 100.

[0087] According to some embodiments of this application, the air conditioner 100 has a first air outlet mode in which the door opening assembly 30 completely avoids the air outlet b and the door opening assembly 30 blocks a portion of the air handling module 20 to prevent the water tank 22 from being disassembled.

[0088] It is understandable that the door opening and closing assembly 30 can switch between the first state, the intermediate state and the second state. When the door opening and closing assembly 30 reaches the maximum intermediate opening width S2, the air outlet b is fully open. At this time, the air conditioner 100 is defined as being in the first air outlet mode, that is, the intermediate air outlet mode in which air is completely discharged through the air outlet b. At this time, the gap area on both sides of the air outlet space when the door opening and closing assembly 31 is in the closed state is blocked by the door opening and closing assembly 31 to improve the air outlet efficiency of the air outlet b and achieve complete intermediate air outlet.

[0089] It should be noted that in the first state, complete lateral airflow can be achieved. Correspondingly, complete lateral airflow can be defined as the second airflow mode. By controlling the opening and closing of the door assembly 30, the switching between the first airflow mode, the second airflow mode, and the mixed airflow mode of partial lateral airflow and partial central airflow can be achieved. In the mixed airflow mode, the lateral airflow volume and the central airflow volume can also be adjusted according to the distance between the two doors 31 to select from multiple airflow modes, which can meet the different usage needs of users and improve the user experience of the air conditioner 100.

[0090] Furthermore, the door opening assembly 30 can be fully opened so that the working mode of the air conditioner 100 after the water tank 22 and humidifier 212 are removed can be defined as a compatible mode. In the compatible mode, the air outlet b is fully open. At this time, the air outlet control logic is the same as the first air outlet mode, and the water tank 22 and humidifier 212 can be removed. This is defined as the compatible mode. In the compatible mode, the air conditioner 100 can still perform heat exchange operations, but the air handling module 20 needs to be shut down to improve the working stability of the air conditioner 100.

[0091] like Figures 7-9 As shown, the air conditioner 100 further includes: a first limiter 50 and a second limiter 60, and a water-filling trigger button 11. The first limiter 50 and the second limiter 60 can cooperate to detect the position of the door opening and closing assembly 30 and control the door opening and closing assembly 30 to stay at a set position or any position between the start point of the travel (the door opening and closing assembly 30 is in the first state) and the end point of the travel (the door opening and closing assembly 20 is in the second state). The water-filling trigger button 11 can be triggered when the user confirms that the water tank 22 or the humidifier 212 needs to be disassembled. After being triggered, the door opening and closing assembly 30 can be switched to the second state.

[0092] Specifically, in an embodiment where the air conditioner 100 can selectively switch between a first air outlet mode and a second air outlet mode, the first limiter 50 is electrically connected to the control module of the air conditioner 100, and the second limiter 60 moves synchronously with the door opening and closing assembly 30. When the first limiter 50 opens and the second limiter 60 is detected, the control module controls the drive assembly 40 to stop running to position the door opening and closing assembly 30 so that the door opening and closing assembly 30 can switch between a first state where the air outlet b is blocked, an intermediate state where the air outlet b is fully open, and a second state. That is, the door opening and closing assembly 30 is controlled to stay at a set position (corresponding to the position in the first air outlet mode) between the start and end of the travel.

[0093] Among them, after the door opening and closing assembly 30 moves to the second state, a limiting member that cooperates with the door opening and closing 31 can be provided on the body 10 to prevent the door opening and closing 31 from moving excessively.

[0094] In an embodiment where the air conditioner 100 also has a mixed air outlet mode, the first limiter 50 is electrically connected to the control module of the air conditioner 100, and the second limiter 60 moves synchronously with the door opening and closing assembly 30. The first limiter 50 opens and detects the relative position of the second limiter 60. The control module is adapted to control the drive assembly 40 to stop moving so that the door opening and closing assembly 30 stops at a suitable position. By recognizing the position between the first limiter 50 and the second limiter 60, the control module can control the door opening and closing assembly 30 to stop at a set position between the start and end of the travel, and can also enable the door opening and closing assembly 30 to stop at any position between the start and the set position, so that the air conditioner 100 has multiple air outlet modes.

[0095] It should be noted that the first limiter 50 includes a first structural part and a detection part, and the second limiter 60 includes a second structural part and a trigger part. The first structural part and the detection part are both fixed on the body 10, and the detection part is electrically connected to the control module. The second structural part and the trigger part are both fixed on the door 31, and the trigger part is adapted to trigger the detection part to identify whether the door 31 has reached the set position or any position required by the user.

[0096] The detection unit can be constructed as any of the following: electromagnetic, photoelectric, differential transformer, eddy current, capacitive, reed switch, or Hall effect position sensor. The triggering unit can be a corresponding triggering structure, such as a metal column or a magnetic column.

[0097] The water-filling trigger button 11 is electrically connected to the control module, and the water-filling trigger can be linked with the liquid level sensor. That is, when the liquid level sensor detects that water needs to be added to the water tank 22, the control module can control the water-filling trigger button 11 to be constantly lit or flashing as needed. After the user observes the water-filling trigger button 11 flashing or constantly lit, pressing the water-filling trigger button 11 can control the door opening and closing assembly 30 to move to the second state.

[0098] Specifically, the first limiter 50 and the second limiter 60 work together to limit the opening and closing door assembly 30 after it reaches the set position. That is, after the air conditioner 100 switches to the first air outlet mode, it can control the opening and closing door 31 to move to the open air outlet b position, and the control module stops supplying power to the drive assembly 40. The opening and closing door 31 stays in this position, realizing the first air outlet mode.

[0099] Based on this, this application further sets up a control logic that controls the first limit switch 50 to stop working when the first limit switch 50 is opened and the water filling trigger key 11 is triggered to issue a water filling command. This is so that when the air conditioner 100 is in the on state and it is necessary to switch the door opening and closing assembly 30 to the second state, the first limit switch 50 will stop detecting by triggering the water filling trigger key 11. This ensures that the door opening and closing assembly 30 will not stop after the door 31 moves to the open air outlet b position during its movement, thereby improving the stability of the door opening and closing assembly 30 during the switching process from the first state or intermediate state to the second state.

[0100] Furthermore, when the water-adding trigger button 11 is triggered to issue a water-adding command, the control module receives a signal to control the door opening / closing assembly 30 to switch to the second state via the drive assembly 40.

[0101] In other words, the air conditioner 100 in this embodiment of the application, by setting a first limiter 50, a second limiter 60 and a water filling trigger button 11, when the water filling trigger button 11 is not triggered, the first limiter 50 and the second limiter 60 cooperate to allow the door 31 to move to the position of fully opening the air outlet b and achieve soft limiting, so as to prevent the door 31 from moving excessively in the first air outlet mode, the second air outlet mode and the mixed air outlet mode, thereby improving the working stability of the air conditioner 100; when the water filling trigger button 11 is triggered, the control module can correspondingly control the first limiter 50 to stop working and control the door 31 to continue moving. After the door 31 moves to the position of opening the air outlet b, it can continue to move to the second state to ensure that the front panel 2132 can be fully opened, which is convenient for the disassembly of the water tank 22 and the humidifier 212, and avoids logical conflicts between the first air outlet mode and the compatible mode.

[0102] It should be noted that the water-adding trigger button 11 can be configured as a virtual button or a physical button. When the water-adding trigger button 11 is configured as a virtual button, vibration feedback can be set accordingly to improve the user experience.

[0103] Furthermore, a water-filling trigger button 11 is located on the body 10, and the water-filling trigger button 11 is configured to issue a water-filling command when it is triggered and lit.

[0104] Specifically, a control panel can be installed on the side or top surface of the body 10, for example, above the door 31 or on the upper short plate. The control panel can integrate a digital display, mode selection, control buttons, etc. At the same time, the water-filling trigger button 11 can be integrated on the control panel. An indicator light can be installed on the control panel. The indicator light is embedded below the button part of the water-filling trigger button 11 so that the water-filling trigger button 11 can emit light or not emit light.

[0105] Furthermore, the water-filling trigger button 11 can interact with the liquid level sensor signal. When water needs to be added to the water tank 22, the indicator light located below the water-filling trigger button 11 can flash to indicate that water needs to be added to the water tank 22. When the user needs to open the front panel 2132, the water-filling trigger button 11 can be triggered. At this time, the water-filling trigger button 11 will remain lit, issuing a water-filling command to indicate that the air conditioner 100 is in compatibility mode. The door opening and closing assembly 30 will switch to the second state. After the user has finished adding water to the water tank 22 or wants to close the front panel 2132, the water-filling trigger button 11 can be triggered again. The door opening and closing assembly 30 will return to the working state before switching to the second state, and the indicator light under the water-filling trigger button 11 will turn off.

[0106] It is understood that the indicator light below the water-adding trigger button 11 of this application has at least three display states: off, flashing, and constantly lit. When water needs to be added to the water tank 22, one of these states can be selected as a prompt. When water addition is complete or when adding water is being done, the other two states can be selected as prompts. The off state is only recognized as the corresponding state prompt if it is triggered to the off state after it is lit.

[0107] like Figure 7 , Figure 8 and Figure 9 As shown, the drive assembly 40 includes: a mounting box 41, a drive component 42, and a moving component 43.

[0108] The mounting box 41 is located on the body 10 and is used to install the drive component 42. The drive component 42 is installed in the mounting box 41 and is electrically connected to the control module. The first limiter 50 is located in the mounting box 41. The moving component 43 is connected to the door opening and closing assembly 30 and the drive component 42 respectively. The drive component 42 drives the moving component 43 to move so as to move the door opening and closing assembly 30. The second limiter 60 is located in the moving component 43.

[0109] Specifically, the mounting box 41 defines a receiving cavity, the driving component 42 is constructed as a driving motor, the motor shaft of the driving motor extends into the receiving cavity and is connected to the moving component 43 through a driving gear, the moving component 43 is constructed as a driving rack, the upper and lower ends of the opening and closing door 31 are provided with driving arms 32, the driving arms 32 extend into the receiving cavity and are connected to the driving rack, a sliding rail is provided in the receiving cavity, and a slider that cooperates with the sliding rail is provided on the driving rack.

[0110] Therefore, the drive motor drives the drive gear to rotate, and the drive gear meshes with the drive rack to drive the switch door 31 connected to the drive rack to move. The cooperation between the sliding rail and the slider can limit the movement of the drive switch door 31 and improve the smoothness of the movement of the switch door 31.

[0111] The first limiter 50 is mounted on the mounting box 41, and the first limiter 50 and the moving member 43 are arranged opposite each other in the height direction. The end of the moving member 43 is provided with a second limiter 60. The moving member 43 slides in the sliding rail so that the second limiter 60 can be opposite to the first limiter 50 to realize the triggering of soft limit. The projection of the first limiter 50 in the height direction is spaced apart from the end of the sliding rail (the end of the stroke) and is located within the stroke range of the sliding rail.

[0112] It is understandable that the extension trajectory of the drive teeth can be constructed as an arc-shaped tooth, and the extension trajectory of the corresponding sliding rail can also be constructed as an arc-shaped rail. That is, the extension trajectory of the drive teeth is consistent with the extension trajectory of the sliding rail, which can effectively improve the smoothness of the opening and closing of the door 31.

[0113] Furthermore, it should be noted that the power transmission between the drive motor and the moving part 43 is not limited to a gear and rack structure. Other drive forms that achieve speed reduction and torque increase or other proportional transmission forms can also be used for driving. This application does not make specific limitations.

[0114] Furthermore, the first limiter 50 is mounted on the mounting box 41, and the second limiter 60 is mounted on the moving part 43 or on the opening / closing door 31, so that the first limiter 50 remains stationary, while the second limiter 60 can move toward or away from the first limiter 50, thereby realizing the detection of whether the opening / closing door 31 is in place in the first air outlet mode and improving the detection accuracy.

[0115] It is understandable that the detection part of the first limiter 50 can be constructed as a Hall sensor, and the trigger part of the second limiter 60 can be constructed as a metal part or a magnetic part, so that when the second limiter 60 approaches or moves away from the first trigger, the detection part of the first limiter will emit different voltages or currents to realize the position detection of the door 31.

[0116] like Figure 11 As shown, the control method of the air conditioner 100 according to the second aspect embodiment of this application includes the following steps:

[0117] Receive the command to vent from the center;

[0118] Control the two switch doors 31 to move away from each other until the first limit switch 50 senses the second limit switch 60, and control the two switch doors 31 to stop moving;

[0119] Upon receiving a water filling command, the first limit switch 50 is stopped and the two opening and closing doors 31 continue to move away from each other until a set position is defined to limit the disassembly space, and the water tank 22 is disassembled from the disassembly space.

[0120] Upon receiving the water filling completion command, the system controls the first limit switch 50 to operate and controls the two switch doors 31 to move towards each other until the first limit switch 50 senses the second limit switch 60 and controls the two switch doors 31 to stop moving.

[0121] Specifically, in this embodiment of the air conditioner 100, after receiving the instruction for the first air outlet mode (i.e., the intermediate air outlet instruction), the control module can control the door opening and closing assembly 30 to move to fully open the air outlet b. In the first air outlet mode, if the user triggers the water filling trigger button 11, the soft limit of the first limiter 50 and the second limiter 60 is further released (i.e., the first limiter 50 is controlled to stop running), and the door opening and closing assembly 30 is controlled to switch to the second state to switch from the first air outlet mode to the compatibility mode. In the compatibility mode, the water tank 22 and the humidifier 212 can be disassembled, and the air conditioner 100 can still exchange heat with the indoor space. After the water filling is completed, according to the water filling completion instruction, the air conditioner 100 is controlled to switch back to the first air outlet mode.

[0122] Of course, the control method of this application embodiment is not limited to this. When the air conditioner 100 is in the off state or the air conditioner 100 is in the second air outlet mode, a water filling command can also be issued through the water filling trigger button 11. Under the water filling command, the soft limit of the first limiter 50 and the second limiter 60 is released, and the door switch 31 is switched to the second state accordingly. After the water filling is completed, the door switch assembly 30 can be controlled to reset to the first state or move to the second state, waiting for further instructions from the user.

[0123] It is understandable that the body 10 is equipped with a water-filling trigger button 11. When the water-filling trigger button 11 is triggered and lit, a water-filling command is issued; when the water-filling trigger button 11 is triggered again and lit, a water-filling completion command is issued. That is, the water-filling trigger button is constantly lit when a water-filling command is issued, and the indicator light changes from constantly lit to off when a water-filling command is issued. The indicator light of the water-filling trigger button 11 is on or off to effectively prompt the user with the current command, making it easier for the user to operate and improving the user experience.

[0124] Below, refer to Figure 4 , Figure 5 The working process of the air conditioner 100 according to the embodiments of this application will be described in detail.

[0125] The air conditioner 100 of this application embodiment includes: a body 10, a water tank 22, two switch doors 31, a first limiter 50 and a second limiter 60. The water tank 22 is detachably disposed on the body 10 and located on one side of the air outlet b.

[0126] Among them, such as Figure 4 As shown, in the first air outlet mode, the two opening and closing doors 31 move to fully open the air outlet b, so that air is discharged from the center through the air outlet b, as shown. Figure 5 In the second air outlet mode, the two doors 31 move to completely block the air outlet b, allowing air to be vented through the gap between the left and right sides of the door assembly 30 and the body 10. A mixed air outlet mode can also be set between the first and second air outlet modes. The compatible mode means that after the door 31 moves to fully open the air outlet b, it moves further to fully expose the front panel 2132 of the air handling module 20. At this time, the water tank 22 and the humidifier 212 can be disassembled by pulling out the bracket 213. In the compatible mode, the air conditioner 100 can perform heat exchange normally.
