[0036] 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.

[0037] The following is for reference. Figures 1-6 An air conditioner 1 according to an embodiment of the present invention is described.

[0038] like Figures 1-6 As shown, the air conditioner 1 according to an embodiment of the present invention includes: an indoor unit module 2 and a function expansion module 3. The indoor unit module 2 includes: an indoor unit housing 21 and an indoor unit heat exchanger 22 disposed in the indoor unit housing 21. The indoor unit housing 21 has a return air vent 211 and a supply air vent 26. The function expansion module 3 is connected to the indoor unit module 2.

[0039] It should be noted that the indoor unit housing 21 may include a front housing 213, a front baffle 214, and a rear housing 215. A return air vent 211 may be provided on the indoor unit housing 21. By providing the return air vent 211 on the indoor unit housing 21, the vertical and horizontal directions of the indoor unit module 2 are considered. The vertical direction of the indoor unit module 2 refers to... Figure 5 The vertical direction in the text refers to the front-back direction of the indoor unit module 2. Figure 5In the front-to-back direction, air can enter the interior of the indoor unit module 2 from the lower and rear sides. It should be noted that the return air vent 211 can be located on the rear housing 215, and also on the front housing 213, near the bottom. The return air vent 211 can communicate with the interior of the indoor unit housing 21, allowing air to flow into the indoor unit housing 21 from the return air vent 211, thus achieving the purpose of air entering the interior of the indoor unit module 2 from the lower and rear sides. The indoor unit heat exchanger 22 is an evaporator component 221. The air conditioner 1 may also include a fan module 222, which is located inside the indoor unit housing 21 and above the evaporator component 221. After the air flows into the indoor unit housing 21 and is cooled or heated by the evaporator component 221, the air can be blown out from the air outlet 26 of the indoor unit module 2 through the fan module 222.

[0040] The evaporator component 221 can be folded multiple times and installed inside the indoor unit casing 21. After multiple folds, the evaporator component 221 can form a serrated structure. This arrangement increases the contact area between the evaporator component 221 and the air, and also reduces the width of the evaporator component 221. It should be noted that the width direction of the evaporator component 221 refers to... Figure 5 In the left and right directions, and the fan module 222 is smaller in size than the existing fan module. By setting the indoor unit heat exchanger 22 inside the indoor unit housing 21, the structure of the indoor unit module 2 of this application is more compact and the volume of the indoor unit module 2 is smaller than that of the prior art, thereby making the air conditioner 1 smaller in size.

[0041] Furthermore, indoor unit module 2 can operate independently as an air conditioner unit. When operating independently, indoor unit module 2 can be used indoors. Indoor unit module 2 can also be used in conjunction with function expansion module 3. That is, indoor unit module 2 can be used alone or in combination with different function expansion modules 3. By combining function expansion modules 3 with indoor unit module 2, the air conditioner 1 can have more functions integrated, thus improving the functionality and versatility of the air conditioner 1. Simultaneously, the combination of indoor unit module 2 and function expansion module 3 results in higher product quality for the air conditioner 1, reducing the likelihood of user complaints.

[0042] Therefore, by combining the indoor unit module 2 and the function expansion module 3, the structure of the air conditioner 1 is more compact compared with the prior art. Furthermore, the air conditioner 1 can be expanded with more functions, making the air conditioner 1 smaller in size, improving its functionality and versatility, thereby improving the product quality of the air conditioner 1 and avoiding user complaints.

[0043] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the function expansion module 3 can be installed on the top of the indoor unit module 2. The lower end of the function expansion module 3 can abut against the top of the indoor unit module 2. Furthermore, the function expansion module 3 can extend along the height direction of the air conditioner 1. It should be noted that the height direction of the air conditioner 1 refers to... Figure 1 The vertical orientation of the air conditioner 1 is designed to make it more aesthetically pleasing. The function expansion module 3 is easier for users to operate and only occupies the vertical space of the air conditioner 1. This avoids increasing the horizontal size of the air conditioner 1, making it suitable for placement in narrow spaces and facilitating its placement.

[0044] In some embodiments of the present invention, such as Figures 1-6 As shown, the air outlet 26 can be located on the top surface of the indoor unit housing 21. The indoor unit module 2 can also include an air supply frame 23, which can be disposed at the air outlet 26, and a function expansion module 3 connected to the air supply frame 23. By disposing of the air outlet 26 on the top surface of the indoor unit housing 21, air flows into the indoor unit module 2 from the return air inlets 211 on the lower and rear sides of the indoor unit housing 21. After being cooled or heated by the evaporator component 221, the air flows sequentially through the fan module 222, the air outlet 26, the air supply frame 23, and the function expansion module 3, finally exiting the indoor unit housing 21 from the air supply frame 23 and / or the function expansion module 3. Furthermore, a sealing plate 24 can be disposed between the air supply frame 23 and the air outlet 26. By disposing of the sealing plate 24, air can be prevented from flowing out between the air supply frame 23 and the air outlet 26, thereby ensuring the air volume supplied by the air conditioner 1. The function expansion module 3 can be fixedly connected to the indoor unit module 2, thereby preventing the function expansion module 3 from falling off the indoor unit module 2.

[0045] In some embodiments of the present invention, such as Figure 5 and Figure 6As shown, the air supply frame 23 can be configured as an annular shape, and the air supply frame 23 has a top opening 27 and a circumferential opening 28. The functional expansion module 3 is connected to the top opening 27, and the functional expansion module 3, the air supply frame 23, and the indoor unit housing 21 are stacked from top to bottom. It should be noted that the indoor unit module 2 can also be provided with a top cover 25. When the indoor unit module 2 is working, the top cover 25 can seal the top opening 27 of the air supply frame 23. After the air is cooled or heated inside the indoor unit module 2, the air can flow out of the indoor unit module 2 through the circumferential opening 28 of the air supply frame 23, thereby achieving the air blowing effect of the air conditioner 1. When the top cover 25 does not seal the top opening 27 of the air supply frame 23, the top cover 25 is removed. After the function expansion module 3 is connected to the indoor unit module 2, the function expansion module 3, the air supply frame 23 and the indoor unit housing 21 are stacked in sequence from top to bottom. The internal space of the function expansion module 3 can communicate with the internal space of the indoor unit module 2 through the top opening 27. After the air is cooled or heated by the indoor unit heat exchanger 22, part of the air can flow out of the indoor unit module 2 through the circumferential opening 28 of the air supply frame 23, and the other part of the air can flow into the internal space of the function expansion module 3 through the top opening 27.

[0046] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the functional expansion module 3 has an expansion module air outlet 31. In the vertical direction of the indoor unit module 2, the expansion module air outlet 31 is located above the circumferential opening 28, and the expansion module air outlet 31 is connected to the air supply frame 23. By setting the expansion module air outlet 31 on the functional expansion module 3, the air flowing into the internal space of the functional expansion module 3 can be blown out from the expansion module air outlet 31. Furthermore, by setting the expansion module air outlet 31 above the circumferential opening 28, the air conditioner 1 can blow air to a higher position, thereby improving the air supply range of the air conditioner 1, as well as its functionality and versatility, and also improving its cooling and heating efficiency.

[0047] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the expansion module air outlets 31 can be two spaced apart, and each expansion module air outlet 31 extends vertically. A mirror structure 32 can be provided between the two expansion module air outlets 31. The expansion module air outlets 31 can be spaced apart in the width direction of the functional expansion module 3, which refers to the left-right direction as described in section 1. Furthermore, the expansion module air outlets 31 can extend vertically along the functional expansion module 3. It should be noted that the vertical direction of the functional expansion module 3 refers to... Figure 1In addition to the vertical orientation of the air conditioner 1, the air outlets 31 of the expansion modules can be symmetrically arranged on the left and right sides of the functional expansion module 3. This arrangement can improve the appearance quality of the air conditioner 1 and make the air blown out by the air conditioner 1 more comfortable. Furthermore, by setting a mirror structure 32 between the two air outlets 31 of the expansion modules, the mirror structure 32 can be set as a mirror, allowing users to apply makeup while looking in the mirror structure 32. The mirror structure 32 can further improve the appearance quality of the air conditioner 1 and also enhance its functionality.

[0048] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the function expansion module 3 can be set at the bottom of the indoor unit module 2. This setting can increase the height of the indoor unit module 2, thereby allowing the indoor unit module 2 to draw in cleaner air, preventing dust accumulation inside the indoor unit module 2, and thus improving the product quality of the air conditioner 1. Furthermore, the function expansion module 3, set at the bottom of the indoor unit module 2, can be constructed as a support base, providing support for the indoor unit module 2, making the air conditioner 1 more stable, preventing the air conditioner 1 from tilting or tipping over, thus preventing damage to the air conditioner 1 and extending its service life.

[0049] In some embodiments of the present invention, such as Figure 4 As shown, the top of the function expansion module 3 can be provided with a positioning part 33 for positioning and connecting with the indoor unit module 2. There can be multiple positioning parts 33, and the indoor unit housing 21 can be provided with positioning holes corresponding to the multiple positioning parts 33. By cooperating with the positioning parts 33 and the positioning holes, the function expansion module 3 can be fixedly connected with the indoor unit module 2, and the connection between the function expansion module 3 and the indoor unit module 2 can be made more secure. Furthermore, by providing the positioning part 33, the assembly of the function expansion module 3 and the indoor unit module 2 can be facilitated.

[0050] In some embodiments of the present invention, the functional expansion module 3 has a bottom walking mechanism 35, which is used to drive the indoor unit module 2 to move. It should be noted that the bottom walking mechanism 35 may be equipped with walking wheels and a drive motor. The drive motor is suitable for driving the walking wheels to rotate, thereby achieving the technical effect of the bottom walking mechanism 35 driving the indoor unit module 2 to move. This arrangement makes it convenient to move the air conditioner 1. Since the position of the air conditioner 1 is not fixed, the air conditioner 1 can be moved at any time as needed, thereby further improving the product quality of the air conditioner 1.

[0051] In some embodiments of the present invention, the function expansion module 3 may have an identification module, and the indoor unit module 2 may have an indoor unit docking part. The identification module is used to identify the outdoor unit docking part of the energy storage module 34 of the air conditioner 1, thereby enabling the indoor unit docking part to dock with the outdoor unit docking part. Specifically, when the identification module identifies the outdoor unit docking part of the energy storage module 34, the bottom walking mechanism 35 drives the indoor unit module 2 to move to the energy storage module 34, allowing the outdoor unit docking part and the indoor unit docking part to dock. It should be noted that the docking of the outdoor unit docking part and the indoor unit docking part can realize the connection of high-voltage and low-voltage electricity between the indoor unit module 2 and the energy storage module 34, and can also realize the connection of pipelines between the indoor unit module 2 and the energy storage module 34. This configuration allows the air conditioner 1 to expand its functions, thereby improving the functionality and versatility of the air conditioner 1.

[0052] In some embodiments of the present invention, such as Figure 3 As shown, the function expansion module 3 can be set on the side of the indoor unit module 2, and the function expansion module 3 can be set on the rear side of the indoor unit module 2, and the function expansion module 3 can abut against the rear side of the indoor unit module 2.

[0053] Furthermore, such as Figure 3 As shown, the functional expansion module 3 at least partially covers the outer periphery of the indoor unit module 2. The outer periphery of the indoor unit module 2 covered by the functional expansion module 3 includes: the top surface of the indoor unit module 2, a portion of the bottom surface structure of the indoor unit module 2, portions of the two side surfaces of the indoor unit module 2 in the width direction, and the rear side surface of the indoor unit module 2. It should be noted that the top and bottom surfaces of the indoor unit module 2 are along... Figure 5 The indoor unit module 2 is spaced apart vertically. This arrangement restricts the movement of the indoor unit module 2 within the function expansion module 3, thereby preventing the indoor unit module 2 from detaching from the function expansion module 3. It also makes the structure of the function expansion module 3 and the indoor unit module 2 compact after connection, thus reducing the space occupied by the air conditioner 1 and making the air conditioner 1 easier to move.

[0054] In some embodiments of the present invention, such as Figure 3 and Figure 4As shown, the energy storage module 34 may include a heat storage structure suitable for storing heat. The indoor unit module 2 can exchange heat with the energy storage module 34. For example, when the air conditioner 1 is heating, the indoor unit module 2 can store heat in the energy storage module 34. Furthermore, both the energy storage module 34 and the indoor unit module 2 are mounted on the bottom traveling mechanism 35. The energy storage module 34 can be snapped onto the bottom traveling mechanism 35, or it can be connected to the bottom traveling mechanism 35 by bolts. By moving the energy storage module 34 and the indoor unit module 2 through the bottom traveling mechanism 35, the air conditioner 1 can be used in different locations, thereby improving the functionality and applicability of the air conditioner 1.

[0055] In some embodiments of the present invention, the function expansion module 3 is retractably connected to the indoor unit module 2. The function expansion module 3 has a storage cavity. It should be noted that the function expansion module 3 can define a storage cavity and can be configured as a drawer-like structure. The function expansion module 3 is retractably connected to the indoor unit module 2. When the user needs to place or retrieve items from the storage cavity, the user pulls out the function expansion module 3. Alternatively, the function expansion module 3 has a hinged door with a storage cavity inside. It should be noted that when the door is open, the user can place or retrieve items from the storage cavity; when the door is closed, the storage cavity is sealed, and objects inside the storage cavity are not exposed to the outside of the air conditioner 1, preventing moisture damage. This configuration enables the air conditioner 1 to have a storage function, thus improving its storage capacity.

[0056] In some embodiments of the present invention, the functional expansion module 3 is connected to the top of the indoor unit module 2. The functional expansion module 3 has a flattened state and a folded state. When the functional expansion module 3 is in the flattened state, it can be flattened and its upper surface is formed as a resting surface suitable for placing items. When the functional expansion module 3 is in the folded state, it is stored on the top of the indoor unit module 2. It should be noted that in this embodiment, the upper cover plate 25 seals the top opening 27 of the air supply frame 23. When the functional expansion module 3 is in the flattened state, the user can place items on the resting surface, thereby enabling the air conditioner 1 to have the function of placing items.

[0057] In some embodiments of the present invention, the functional expansion module 3 can be configured as a cooking device, a refrigeration device, a washing device, a drying module, or an air purification module. It should be noted that the cooking device can be an oven or a microwave oven, the refrigeration device can be a refrigerator, the washing device can be a washing machine, the drying module can be a dryer, and the air purification module can be an air purifier. This configuration enables the air conditioner 1 to integrate cooking, refrigeration, washing, drying, and air purification functions, thereby expanding the applicability of the air conditioner 1. Furthermore, the functional expansion module 3 can also be configured as a wardrobe, and the indoor unit module 2 can be integrated with the wardrobe.

[0058] In some embodiments of the present invention, the function expansion module 3 may be provided with a first docking part, and the indoor unit module 2 may be provided with a second docking part, wherein the first docking part and the second docking part are matched and docked.

[0059] Optionally, the first docking part and the second docking part are configured as positioning structures. The first docking part can be configured as a positioning protrusion, and the second docking part can be configured as a positioning groove. When assembling the function expansion module 3 and the indoor unit module 2, the positioning protrusion and the positioning groove are used for installation, which facilitates the assembly of the function expansion module 3 and the indoor unit module 2, thereby improving the installation efficiency of the function expansion module 3 and the indoor unit module 2.

[0060] Alternatively, the first and second docking parts can be configured as high-voltage and / or low-voltage docking parts. It should be noted that when the first and second docking parts are configured as high-voltage docking parts, the first docking part can be configured as a socket (220V), and the second docking part as a plug. After the first and second docking parts are connected, high-voltage connection between the function expansion module 3 and the indoor unit module 2 can be achieved. When the first and second docking parts are configured as low-voltage docking parts, signal transmission between the function expansion module 3 and the indoor unit module 2 can be achieved, thereby improving the information exchange capability between the function expansion module 3 and the indoor unit module 2.

[0061] Alternatively, the first and second docking parts can be configured as fluid medium docking parts. It should be explained that when the functional expansion module 3 is configured as a drying module, the gas blown out by the indoor unit module 2 can flow into the drying module through the first and second docking parts, and the gas flowing into the drying module can be used to dry items. Furthermore, when the functional expansion module 3 is configured as a refrigeration device, the refrigerant blown out by the indoor unit module 2 can flow into the refrigeration device through the first and second docking parts, and the refrigerant flowing into the refrigeration device can be used for refrigeration. Moreover, when the indoor unit module 2 needs to refrigerate, the refrigerant in the refrigeration device can flow into the indoor unit module 2 through the first and second docking parts, and the refrigerant is used for refrigeration within the indoor unit module 2.

[0062] In some embodiments of the present invention, the function expansion module 3 and the indoor unit module 2 are controlled in association. This can also be understood as the function expansion module 3 and the indoor unit module 2 can be controlled to work or not work at the same time.

[0063] In some embodiments of the present invention, the indoor unit module 2 may be provided with an identification unit for identifying the type of the functional expansion module 3. The air conditioner 1 has a display and control component, which communicates with the identification unit and is used to display and / or control the operating status of the identified functional expansion module 3. After the identification unit identifies the type of the functional expansion module 3, it can send the operating status information of the functional expansion module 3 to the display and control component. The display and control component then displays and / or controls the operating status of the identified functional expansion module 3, allowing the user to understand the working status of the functional expansion module 3 in real time.
