[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] In the description of the present invention, if there is a description of first, second, etc., it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0038] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, left, right, front, and back, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] refer to Figures 1 to 8 The air-conditioning indoor unit 10 of the embodiment of the present invention is described. The air-conditioning indoor unit 10 should be understood in a broad sense. That is, the air-conditioning indoor unit 10 can be a cabinet-type air-conditioning indoor unit, a wall-mounted air-conditioning indoor unit, etc. The embodiment of the present invention is described with reference to the cabinet-type air-conditioning indoor unit 10.

[0041] See also Figure 1 and 2As shown, the air conditioning indoor unit 10 of an embodiment of the present invention includes a housing 100, with an air outlet 111 and a heating module 200 disposed on the front side of the housing 100. The air outlet 111 communicates with an air duct 131 inside the housing 100, which serves as an air supply channel for cooling or heating the air conditioning indoor unit 10. The heating module 200 is fixedly mounted on the front side of the housing 100. The heating module 200 radiates heat toward the front of the air conditioning indoor unit 10, providing auxiliary heating and rapidly warming the indoor environment.

[0042] The back of the heating module 200 faces the inside of the housing 100, and air can be supplied to the back of the heating module 200 through the air duct 131, thereby dissipating heat from the heating module 200. It can be understood that the front of the heating module 200 is the surface that radiates heat outward and faces the outside of the housing 100, while the back of the heating module 200 faces the inside of the housing 100. The heating module 200 is an infrared heat radiation module that can radiate heat outward from the front during operation. Since the back of the heating module 200 also generates a certain amount of heat, in this embodiment, the air duct 131 is connected to the back of the heating module 200, and the airflow formed in the air duct 131 is used to remove the heat generated by the back of the heating module 200, so that the back of the heating module 200 is dissipated, achieving an effective heat dissipation effect and reducing the impact of the heating module 200 heating and temperature rise on the internal parts of the air conditioner indoor unit 10.

[0043] It is understood that the heating module 200 can be installed close to the air duct 131, and the back of the heating module 200 can extend directly into the air duct 131. In this way, when the airflow is blown out through the air duct 131, it can simultaneously dissipate heat from the back of the heating module 200. The heat generated on the back of the heating module 200 can be discharged from the air outlet 111 along with the airflow, resulting in a significant heat dissipation effect. It is easy to imagine that a channel connected to the air duct 131 can be added to the inner side of the housing 100. The air duct 131 is connected to the back of the heating module 200 through the channel. The airflow in the air duct 131 can dissipate heat from the back of the heating module 200 through the channel, thereby reducing the impact of heating and temperature rise on the internal parts of the air conditioner indoor unit 10 and ensuring the stability of the operation of the air conditioner indoor unit 10.

[0044] It can be understood that the heating module 200 is installed on the front side of the housing 100, and the heating module 200 is used to radiate heat toward the front of the housing 100. For the cabinet air-conditioning indoor unit 10, the heating module 200 can generate heat radiation when it is powered on, which can provide the user with an instant radiant heat sensation. Compared with the heat pump output heating mode, the heating efficiency is higher, which is particularly suitable for cold environments. It effectively avoids the user's discomfort, hot head and cold feet caused by low output efficiency, and improves the user experience. When in use, the heating module 200 can be used alone for heating, or it can be used in conjunction with the heat pump output of the air-conditioning indoor unit 10 for heating, that is, the heating module 200 and the heat pump output are run at the same time for heating, which can realize the selection of different operating modes, meet different experience scenarios with higher temperature and light intensity, and provide a better user experience.

[0045] It should be noted that the installation position of the heating module 200 is the front side of the shell 100, which should be understood to include but not be limited to the front position, and can also be located at the left front or right front position, so that the heat radiation generated by the heating module 200 can diffuse forward to achieve rapid heating.

[0046] See also Figure 2 and 3 As shown, in some embodiments, a heat dissipation hole 211 is provided on the front side of the heating module 200, and the heat dissipation hole 211 is connected to the back side of the heating module 200. The heat dissipation hole 211 can be understood as a through hole that runs through the front and back sides of the heating module 200. In this way, the air duct 131 can be connected to the heat dissipation hole 211, and the airflow generated by the air duct 131 can pass through the back side of the heating module 200 and blow out along the heat dissipation hole 211. In this way, the airflow can take away the heat from the back side of the heating module 200, reducing the heat diffusion toward the inside of the housing 100, thereby reducing the impact of heat on internal parts and achieving better heat dissipation. At the same time, as the airflow absorbs heat and heats up, the airflow blown out of the heat dissipation hole 211 forms hot air, which is heated by the hot air combined with heat radiation, thereby achieving heat dissipation and improving heating efficiency, thereby improving heat utilization.

[0047] Specifically, the heat dissipation holes 211 are located on the front of the heating module 200 and are distributed along the periphery of the heating module 200. The heat dissipation holes 211 can be long strips, circles or other shapes. The number and aperture of the heat dissipation holes 211 can be set according to actual requirements, and will not be further explained in the embodiment of the present invention.

[0048] See also Figure 3As shown, in some embodiments, the heating module 200 includes a heating tube 220 and a reflective cover 210, wherein the side of the reflective cover 210 facing the outside of the housing 100 is a reflective surface 212, and the back of the reflective cover 210 faces the inside of the housing 100, that is, the back of the reflective cover 210 is connected to the air duct 131. The heating tube 220 is located on one side of the reflective surface 212. The heating tube 220 used is an infrared radiation heating tube, for example, a quartz heating tube or a carbon fiber heating tube. When in operation, the heating tube 220 is energized to generate heat radiation, and the reflective cover 210 can reflect the infrared heat radiation toward the outside of the housing 100, so that the heat radiation generated by the heating tube 220 can be concentrated and diffused toward the front of the air conditioner indoor unit 10, reducing heat loss, effectively improving heating efficiency, and providing users with a more efficient radiant heat sensation.

[0049] See also Figure 3 As shown, specifically, the reflector 210 is an arc-shaped body with a rectangular shape, and heat dissipation holes 211 are provided on both sides of the reflector 210 and distributed along its length. It can be understood that the back of the reflector 210 is convex and arc-shaped, and the heat dissipation holes 211 are located on both sides of the back. The airflow of the air duct 131 can flow along the arc-shaped surface of the back of the reflector 210 to the heat dissipation holes 211. In this way, the heat on the back of the reflector 210 can be quickly carried away by the airflow, effectively reducing the temperature of the back of the reflector 210 and achieving a significant heat dissipation effect. As can be readily appreciated, the length of the reflector 210 can be determined based on the size of the heating tube 220. The heating tube 220 can be a straight tube or a U-shaped tube. The heat dissipation holes 211 can be circular or elongated. The reflector 210 is not limited to the rectangular shape shown in the embodiment, and can also be square, oval, etc.

[0050] See also Figure 3 As shown, in some embodiments, the reflective cover 210 is made of stainless steel, and the reflective surface 212 of the reflective cover 210 is a stainless steel mirror. The mirror is curved and has high heat resistance and corrosion resistance. The surface is polished to form a mirror with high reflectivity, which can effectively reflect the heat radiation generated by the heating tube 220. The structure is practical, reliable, firm and stable.

[0051] See also Figure 3 and 4 As shown, in some embodiments, the heating module 200 includes a heating tube 220, a reflector 210, and a mounting box 230. The mounting box 230 has a cavity that matches the reflector 210. The reflector 210 is installed in the cavity, and the heating tube 220 is installed in front of the reflective surface 212. The heating module 200 is fixed to the housing 100 via the mounting box 230.

[0052] The front of the mounting box 230 is open, matching the opening with the reflector 210, allowing the reflective surface 212 to face the outside of the mounting box 230. The back of the mounting box 230 is provided with an air inlet hole 231, which communicates with the air duct 131. A heat dissipation channel 232 is formed between the inner wall of the mounting box 230 and the reflector 210, connecting the heat dissipation holes 211 and the air inlet hole 231. In this way, airflow from the air duct 131 can sequentially pass through the air inlet hole 231 and the heat dissipation channel 232 before being blown out of the heat dissipation holes 211, thereby quickly removing heat from the reflector 210, effectively reducing the temperature of the reflector 210 and achieving optimal heat dissipation. Figure 4 The direction indicated by the arrow is the direction of air flow.

[0053] It can be understood that the heat dissipation holes 211 are provided on both sides of the reflector 210 and are distributed along the length thereof. The heat dissipation channels 232 are located on both sides of the reflector 210 and extend along the length thereof. The heat dissipation channels 232 serve as air guides, allowing air to flow through the back of the reflector 210 and be quickly discharged through the heat dissipation holes 211, thereby achieving efficient heat dissipation. Preferably, the back of the mounting box 230 is hollowed out to form the air inlet holes 231, so that the air inlet holes 231 have a sufficiently large aperture to meet the requirements of a large air intake volume and effectively improve the heat dissipation effect.

[0054] See also Figure 3 and 4 As shown, in some embodiments, a glass panel 240 is provided on the mounting box 230. The glass panel 240 is made of tempered glass and covers the reflector 210. That is, the front of the reflector 210 is covered by the glass panel 240, preventing the heating tube 220 from being exposed. Because tempered glass does not easily absorb heat radiation, the surface of the glass panel 240 does not reach high temperatures during the heating process, thereby avoiding safety issues such as burns caused by excessive surface temperatures. Moreover, the use of tempered glass to make the glass panel 240 provides higher safety. It can be understood that the area covered by the glass panel 240 does not block the heat dissipation holes 211, thereby avoiding affecting the air outlet of the heat dissipation holes 211.

[0055] See also Figure 1 and 5As shown, two heating modules 200 are provided on the housing 100, and the heating modules 200 are provided near the air outlet 111. Specifically, the air conditioning indoor unit 10 of the embodiment is a cabinet-type air conditioning indoor unit using a cross-flow fan, and the air outlet 111 is provided in the middle of the front of the housing 100. The two heating modules 200 are respectively located on both sides of the air outlet 111 and extend along the height direction of the air outlet 111, so that the heating modules 200 can radiate heat toward the front, providing the user with an instant radiant heat sensation, achieving rapid heating, and effectively solving the problems of discomfort, hot head and cold feet caused by low heating efficiency during use, thereby improving the user experience. It can be understood that the heating modules 200 are installed using a modular structure, which is flexible and convenient to install. The number of heating modules 200 is not limited to the number shown in the embodiment, and the heating modules 200 are not limited to cabinet-type air conditioning indoor units, but can also be applied to wall-mounted air conditioning indoor units.

[0056] See also Figure 5 As shown, in some embodiments, an air outlet frame 120 is provided inside the housing 100. The air outlet frame 120 is positioned between the air outlet 111 and the air duct 131. A diversion channel 121 is provided on the air outlet frame 120. One end of the diversion channel 121 is connected to the air duct 131, and the other end is connected to the heating module 200. Specifically, the air conditioner indoor unit 10 includes a fan assembly 130 and an evaporator assembly 140. The fan assembly 130 is a cross-flow fan. The air duct 131 is formed on the fan assembly 130. The evaporator assembly 140 is disposed outside the fan assembly 130. An air inlet 151 corresponding to the evaporator assembly 140 is provided on the back of the housing 100. The specific structures of the fan assembly 130 and the evaporator assembly 140 are within the knowledge of those skilled in the art and will not be further described here.

[0057] See also Figure 5 As shown, the air outlet frame 120 is installed on the fan assembly 130, and an air outlet channel 122 corresponding to the air duct 131 is provided on the air outlet frame 120. The air outlet channel 122 corresponds to the air outlet 111. The air outlet channel 122 is located in the middle of the air outlet frame 120, and the diversion channel 121 is provided on both sides of the air outlet channel 122. Figure 6 As shown, one end of the diversion channel 121 is connected to the air duct 131, and the other end is connected to the installation box 230, so that the air inlet hole 231 on the back of the installation box 230 can be connected to the air duct 131 through the diversion channel 121.

[0058] It can be understood that the diversion channel 121 has a diversion effect. When the airflow formed by the fan assembly 130 is blown out along the air duct 131, a part of the airflow can enter the heating module 200 along the diversion channel 121 to dissipate heat for the heating module 200, which has a better heat dissipation effect. The hot air formed by the airflow blowing out from the heat dissipation holes 211 on the front of the heating module 200, that is, the heating module 200 uses heat radiation to heat the outside while being able to heat with the hot air blown out from the heat dissipation holes 211, which makes the heating more efficient. In this way, the heat dissipation purpose can be achieved, and the heat dissipated by the heating module 200 toward the inside of the shell 100 can be reused to reduce the diffusion of heat to the inside, thereby reducing the impact of temperature rise on internal parts and ensuring the stable operation of the air-conditioning indoor unit 10.

[0059] See also Figure 5 As shown, the housing 100 includes a front shell 110 and a rear shell 150. The air outlet 111 is located on the panel of the front shell 110, and the air inlet 151 is located on the back of the rear shell 150. The air inlet 151 is provided with an air inlet grille 152. During installation, the heating module 200 is fixedly mounted on the front shell 110. A heating module 200 is provided on both sides of the air outlet 111. The air outlet 111 corresponds to the air outlet channel 122 on the air outlet frame 120, connecting the air outlet 111 with the air duct 131. The backs of the two heating modules 200 can be respectively inserted into the diversion channel 121, connecting the air inlet hole 231 with the air duct 131. This makes installation easy and the structure practical and reliable.

[0060] See also Figures 6 to 8 As shown, in some embodiments, the air outlet frame 120 is provided with an air guide plate 123, which is located at the entrance of the diversion channel 121. The size of the air guide plate 123 matches the size of the entrance of the diversion channel 121. In this way, the diversion channel 121 can be opened or closed by the air guide plate 123, that is, the diversion channel 121 can be controlled to be connected or closed with the air duct 131. Specifically, the upper and lower ends of the air guide plate 123 are respectively connected to the air outlet frame 120 via a rotating shaft, and the air guide plate 123 is driven by a first motor to rotate about the rotating shaft, thereby realizing the opening or closing of the air guide plate 123.

[0061] See also Figure 5As shown, in some embodiments, the air outlet frame 120 is further provided with a door panel 124, through which the air outlet 111 can be opened or closed. The door panel 124 is driven by a second motor 125 to slide horizontally left and right. When the door panel 124 moves to the position of the air outlet channel 122, the door panel 124 can block the connection between the air outlet 111 and the air duct 131, thereby closing the air outlet 111. When the door panel 124 moves to the side and away from the air outlet channel 122, the air outlet 111 and the air duct 131 can be connected, thereby opening the air outlet 111. The second motor 125 can drive the door panel 124 to move via a transmission assembly such as a gear rack. The specific structure of the transmission assembly is well known to those skilled in the art and will not be described in detail here.

[0062] It is easy to understand that the heating module 200 can operate independently for heating, or it can be combined with the heat pump output heating mode of the air conditioner indoor unit 10 to achieve different operating modes. In different operating modes, the air guide plate 123 can be used to control the opening or closing of the diversion channel 121, and the door panel 124 can be used to control the opening or closing of the air outlet 111, thereby achieving an optimal heating effect.

[0063] See also Figure 6 As shown, when the air conditioner indoor unit 10 is in heat pump independent operation mode, the heating module 200 is inactive, the air guide plate 123 is closed, and the diversion channel 121 is closed. Simultaneously, the door panel 124 is open, the evaporator assembly 140 and the fan assembly 130 are operating, and the generated air is completely delivered through the front air outlet 111 for heating. In this operating state, the heating module 200 and the diversion channel 121 do not affect the air output of the air duct 131, ensuring the performance output of the air conditioner indoor unit 10 in both cooling and heating conditions.

[0064] See also Figure 7 As shown, when the air-conditioning indoor unit 10 turns on the heat pump and heat radiation operating mode, the heating module 200 is turned on, and at this time the air guide plate 123 and the door panel 124 are both opened, the evaporator assembly 140 and the fan assembly 130 are in operation, and the diversion channel 121 and the air outlet 111 are simultaneously connected to the air duct 131, and the wind generated by the fan assembly 130 can be sent out from the air outlet 111 and the diversion channels 121 on the left and right sides, that is, three channels are formed to discharge airflow. In this way, the heat pump output heating and heat radiation are combined for heating, which has higher heating efficiency, can provide users with instant radiant heat feeling, and have a better user experience. In addition, the airflow in the diversion channel 121 can dissipate heat and cool the heating module 200, effectively solving the heat dissipation problem of the heating module 200, with significant heat dissipation effect, reducing the diffusion of heat to the inside of the air-conditioning indoor unit 10, thereby reducing the impact of temperature rise on internal parts and ensuring the stable operation of the air-conditioning indoor unit 10.

[0065] See also Figure 8As shown, when the air-conditioning indoor unit 10 turns on the heat radiation independent operation mode, the heating module 200 is turned on, the air guide plate 123 is opened, the door panel 124 is closed, the evaporator assembly 140 is not working, and the wind generated by the fan assembly 130 is blown to the heating module 200 from the diversion channels 121 on the left and right sides, thereby dissipating the heat of the heating module 200 and reducing the diffusion of heat to the inside of the air-conditioning indoor unit 10, thereby reducing the impact of temperature rise on internal parts, and ensuring the safe and reliable operation of the air-conditioning indoor unit 10 when the heat radiation mode is turned on.

[0066] An air conditioner according to an embodiment of the present invention will be described below, including the air conditioner indoor unit 10 according to the above embodiment.

[0067] Taking a cabinet-type indoor air conditioner 10 as an example, the air conditioner of the embodiment of the present invention includes the indoor air conditioner 10 and an outdoor air conditioner. The structure of the outdoor air conditioner is not shown in the accompanying drawings. The heating module 200 radiates heat toward the front of the indoor air conditioner 10, providing the user with an immediate radiant heat sensation. This can be combined with the heat pump output of the indoor air conditioner 10 to effectively improve heating efficiency and enhance user comfort. The air duct 131 can also supply air to the back of the heating module 200. During operation, the airflow of the air duct 131 can remove the heat generated by the back of the heating module 200, thereby dissipating heat from the heating module 200. This significantly reduces the impact of the heating module 200 on the internal components of the indoor air conditioner 10 due to heating and temperature rise, ensuring that the heating module 200 does not affect the normal operation of the indoor air conditioner 10, improving the stability of the air conditioner operation, and making it more practical and reliable.

[0068] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
