Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a duct structure for a bed-type air conditioner and the bed-type air conditioner itself. Background Technology

[0002] Existing air conditioners are typically mounted on walls or windowsills, taking up space and affecting the overall aesthetics of the room. Furthermore, the air vents are usually located high up in the room, easily blowing directly on people and affecting sleep quality. Specifically, the design of traditional air conditioner vents is spatially misaligned with the area where people move. When cold or hot air blows vertically or obliquely from above onto the body, it can easily cause sudden changes in local temperature, leading to frequent tossing and turning during sleep or waking up due to discomfort. Manually adjusting the vent direction to avoid direct airflow reduces air conditioning efficiency, requiring the entire room's air to be heated / cooled to achieve temperature equilibrium, resulting in increased energy consumption and slow response time.

[0003] Studies have shown that the human body is significantly more sensitive to airflow during sleep than when awake. Existing air conditioners fail to guarantee localized comfort and increase energy waste due to prolonged operation. Although some products optimize airflow range by adding louvers or air guide structures, their adjustment logic remains based on fixed programs or manual control. Therefore, how to improve airflow efficiency and achieve imperceptible airflow while avoiding direct airflow interference remains a challenge that current technology has not yet solved. Utility Model Content

[0004] In order to solve the technical problems of low air supply efficiency and poor comfort in the prior art, this utility model proposes a duct structure for a bed-type air conditioner and a bed-type air conditioner.

[0005] The technical solution adopted in this utility model is:

[0006] This utility model proposes a duct structure for a bed-type air conditioner, comprising: a bed body, an air inlet provided at the bottom or side of the bed body, an air outlet provided at the head and / or foot of the bed body, an air duct connecting the air inlet and the air outlet inside the bed body, and a fan component provided inside the air duct.

[0007] Furthermore, the bed frame is positioned with the air vent at the head of the bed facing upwards.

[0008] Furthermore, the fan component includes: a cross-flow fan, and an air guide component that covers the cross-flow fan and directs airflow towards the head and / or foot of the bed.

[0009] Preferably, two cross-flow fans are provided, with the two cross-flow fans spaced apart, and the air inlet is located below the space between them. The air guiding component includes two air guide covers that respectively cover the two cross-flow fans to guide air to the head and foot of the bed.

[0010] Furthermore, the duct is provided with a first side plate and a second side plate at the two ends of the cross-flow fan, and a first rodent-proof plate that connects the first side plate and the second side plate and blocks the air outlet side of one cross-flow fan, and a second rodent-proof plate that connects the first side plate and the second side plate and blocks the air outlet side of the other cross-flow fan.

[0011] Furthermore, the air inlet is equipped with an air inlet panel component that can be opened and closed.

[0012] The air intake panel components include:

[0013] The mounting bracket is installed on the pre-reserved opening on the bottom surface of the bed. The mounting bracket covers the bottom of the fan component and has the air inlet. The mounting bracket extends downward into a mounting groove.

[0014] An air intake drive component is installed in the mounting slot;

[0015] The air inlet panel opens and closes the opening of the mounting slot via the air inlet drive component.

[0016] This utility model also proposes a bed-type air conditioner, characterized in that it includes the above-mentioned air duct structure and a heat exchanger corresponding to the fan component.

[0017] Furthermore, the heat exchanger is located on the outlet side of the cross-flow fan, and the end face of the heat exchanger is V-shaped, with the opening of the V-shape facing the cross-flow fan.

[0018] Furthermore, it also includes a waterbed layer laid on the bed body, the waterbed layer being equipped with a water outlet pipe, and the waterbed layer being circulated in connection with a circulation component that can provide cooling and heating.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. By utilizing the sinking properties of cold air through a special air duct, the user is prevented from being directly exposed to cold air, thus achieving "cold air does not blow on people," meeting the user's needs, avoiding various discomforts caused by direct cold air, significantly improving sleep quality, and enhancing the user experience.

[0021] Furthermore, by utilizing the rising property of hot air, it creates a thermal curtain from the bottom, insulating against cold air from the outside and maintaining the internal temperature, ensuring a consistently warm and comfortable environment. This design not only enhances the user experience but also ensures a uniform distribution of indoor temperature, truly achieving the beneficial effect of a constant and comfortable home environment.

[0022] 2. The waterbed design, combined with heated water pipes, enables precise heat radiation to the human body even in extremely low indoor temperatures. This not only provides a warm and comfortable sleeping environment during cold winters but also works in conjunction with air conditioners to further improve the overall indoor temperature.

[0023] 3. It makes good use of the large usable area of ​​the bed by embedding the indoor unit of the bed-type air conditioner, which not only saves space and achieves an aesthetic design, but also makes the bed more functional. Because the volume of the embedded air conditioner is much larger than that of ordinary indoor units, it can also improve the heat exchange effect and enhance comfort.

[0024] 4. The system adopts a dual cross-flow fan, with airflow entering from all four sides of the air inlet panel. Without affecting the airflow, the special structural design can absorb and reflect some of the noise from the fan system, thereby reducing the total noise level and noise pollution. It also makes it easier to embed the air conditioner into the bed. Attached Figure Description

[0044] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0045] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0046] In traditional air conditioning heating mode, hot air rises naturally due to its lower density, resulting in a significantly higher temperature at the top of the room compared to areas where people move around (such as the bed or chair), creating a pronounced "hot head, cold feet" phenomenon. Experimental data shows that after 30 minutes of air conditioning operation, the vertical temperature difference in a room can reach 5°C to 8°C, far exceeding the range of comfortable temperature differences for the human body. Especially in winter sleeping scenarios, insufficient warmth in the feet can easily lead to poor blood circulation and a feeling of cold, while excessive heat in the head can cause dryness, night sweats, and other problems. Although some air conditioners attempt to bridge the temperature difference by adding circulating fans or air deflectors, these solutions only dilute the local temperature difference by expanding the airflow range and cannot fundamentally address the physical characteristic of hot air rising. Furthermore, continuously running the air conditioner to reduce the temperature difference significantly increases energy consumption, and the frequent start-stop cycles cause temperature fluctuations that further exacerbate discomfort.

[0047] In this regard, such as Figure 1 , 2 As shown, this utility model proposes a bed-type air conditioning duct 11 structure, including: a bed body 1 and a fan component 2. Specifically, the bed body 1 includes a bed frame and a headboard. The headboard is connected to the end of the bed frame and extends upwards. An air inlet is provided at the bottom or side of the bed frame to introduce external air. This embodiment uses a bottom-mounted air inlet as an example. The location of the air inlet of the bed body 1 can be selected from the bottom or side depending on the actual installation environment, facilitating adaptation to different room layouts. Air outlets are provided at the top of the headboard and the end face of the footboard of the bed body 1 to achieve directional air exhaust (it should be noted that an air outlet can also be provided only at the top of the headboard, or only at the footboard). The bed body 1 integrates an air duct 11 connecting the air inlet and the air outlet. The path of this air duct 11 is designed as a smooth airflow channel according to the structure of the bed body 1, ensuring that air enters from the air inlet, circulates internally, and is finally delivered from the air outlet. This allows for concentrated airflow to the user's sleeping area or the formation of a surrounding airflow circulation. The fan component 2 is installed inside the air duct 11, and its function is to drive the airflow to form a continuous airflow channel between the air inlet and the air outlet. The fan component 2 generates an air pressure difference by directional rotation, which pushes the air to be drawn in from the air inlet, transported through the air duct 11, and then evenly discharged from the air outlet.

[0048] This structure, by placing air outlets at the head and foot of the bed frame 1, achieves directional airflow within the bed frame 1. Compared to the long-distance air delivery method of traditional air conditioners, the air duct structure 11 of the bed-type air conditioner can more precisely control the airflow direction, improving temperature uniformity and comfort in local areas. Figure 4 As shown, in heating mode, utilizing the rising property of hot air, the hot air rises from the bottom to form a thermal curtain, which insulates against cold air from the outside, thus maintaining the internal ambient temperature and ensuring a consistently warm and comfortable feeling for the human body. This design not only enhances the user experience but also ensures a uniform distribution of indoor temperature, truly achieving the beneficial effect of a constant and comfortable home environment.Figure 5 As shown, in cooling mode, the sinking property of cold air can be used to prevent cold air from blowing directly on the human body and to cool down quickly.

[0049] In a further embodiment, such as Figure 4 , 5 As shown, the air vents at the head of the bed frame 1 are arranged upwards. This design allows air to be exhausted from the head of the bed upwards, forming a vertical upward airflow. The upward-facing air vents effectively prevent the airflow from blowing directly onto the user's head or body, thereby improving comfort and health. At the same time, this airflow direction facilitates air diffusion within the room, promoting overall air circulation, which is especially suitable for scenarios requiring uniform temperature distribution. The upward-facing design of the air vents seamlessly connects with the internal air duct 11 of the bed frame 1, ensuring smooth and stable airflow during output, further enhancing the operational efficiency of the air duct 11 structure.

[0050] The air duct 11 is specifically L-shaped, with the upper end being the air outlet at the head of the bed and the right end being the air outlet at the foot of the bed. The air duct 11 has a simple structure and a smooth transition at the corner, which improves ventilation efficiency. An air inlet is set at the bottom of the bed, that is, the air inlet is set in the middle of the horizontal part of the L-shape. At the same time, a sound-absorbing filter 44 can be set at the air inlet to reduce the noise of the fan operation.

[0051] Specifically, such as Figure 5 , 6 As shown in Figure 7, the fan component 2 includes a cross-flow fan 21 and an air guide component. The cross-flow fan 21 is installed in the air duct 11 inside the bed body 1, and adopts a multi-blade axial structure to form a stable linear airflow through high-speed rotation. Specifically, the two ends of the cross-flow fan 21 face the sides of the bed body 1, and the air guide component covers the outside of the cross-flow fan 21. Its inner wall has an arc-shaped or baffle-like structure, which can guide the airflow towards the head or foot of the bed as needed. The cooperative design of the air guide component and the cross-flow fan 21 realizes the control of the airflow direction and avoids disorderly diffusion. When air needs to be supplied to the head of the bed, the guide surface of the air guide component concentrates and guides the airflow to the air outlet at the head of the bed; similarly, the structure of the air guide component can also be set to supply air directionally to the foot of the bed or to supply air synchronously in both directions to the head and foot of the bed as needed. This design reduces turbulence loss and improves fan efficiency by optimizing the airflow path, while supporting flexible switching of airflow direction to adapt to the cooling or heating needs of different sleeping areas.

[0052] In a preferred embodiment, the fan component 2 adopts a dual cross-flow fan 21 layout. Two sets of cross-flow fans 21 are arranged horizontally at intervals, with the gap between them directly opposite the air inlet, allowing external air to enter the fan's suction area evenly through the air inlet below the gap. The air guiding component includes two independent air guide hoods 22, each covering a corresponding cross-flow fan 21. The front air guide hood 22 near the head of the bed guides airflow towards the head of the bed through its inner curved surface, while the rear air guide hood 22 near the foot of the bed guides airflow towards the foot of the bed through a reverse airflow structure. The arrangement of the dual cross-flow fans 21, combined with the split air guide hoods 22, forms a directional airflow distribution path: the front cross-flow fan 21 outputs airflow to the head of the bed through the front air guide hood 22, and the rear cross-flow fan 21 delivers airflow to the foot of the bed through the rear air guide hood 22. The design achieves independent air supply at both ends of the bed 1 through dual-channel airflow separation. At the same time, the layout of the air inlet located below the gap between the two fans shortens the air entry path, reduces air intake resistance, and improves the overall heat exchange efficiency.

[0053] In a further embodiment, a first side plate 24 and a second side plate 25 are provided inside the duct 11 at both ends of the cross-flow fan 21 as a longitudinal support frame. A first rodent-proof plate 26 is installed at the front end connection of the first side plate 24 and the second side plate 25. This rodent-proof plate is located on the air outlet side of the front cross-flow fan 21 and is made of metal mesh or perforated plate material, preventing foreign objects from entering while maintaining unobstructed airflow. Similarly, a second rodent-proof plate 27 is provided at the rear end connection of the first side plate 24 and the second side plate 25, corresponding to the air outlet side of the rear cross-flow fan 21 for protection. The rodent-proof plate and the side plates form a closed protective structure, preventing dust and small animals from flowing back into the fan from the air outlet and avoiding direct exposure of the blades, thus preventing safety hazards. The combined design of the side plates and the rodent-proof plate also enhances the rigid support inside the duct 11, ensuring the structural stability of the dual cross-flow fans 21 during high-speed operation while maintaining the integrity of the airflow guidance path.

[0054] In a specific embodiment, the air inlet is equipped with an openable air inlet panel component 4, which is mounted on the bed frame 1. The air inlet panel 43 can be connected via a linkage or slide rail structure, allowing for manual or automatic adjustment of its opening and closing as needed. When closed, the air inlet panel 43 effectively prevents external dust and foreign objects from entering. Furthermore, the panel surface can be integrated with an antibacterial coating or electrostatic adsorption layer for primary purification of the incoming air. This design improves airflow controllability during equipment operation, facilitates regular cleaning and maintenance, and allows the panel to be closed during non-use periods.

[0055] In a further embodiment, such as Figure 6 As shown, the air inlet panel component 4 includes: a mounting bracket 41, an air inlet drive component, and an air inlet panel 43.

[0056] Mounting bracket 41 is fixed to the bottom opening of bed frame 1, covering the area below fan component 2, acting as a cover for the fan component 2, and forming an air inlet at the bottom. Mounting bracket 41 extends downwards into a recessed mounting groove to accommodate the drive component and conceal the internal mechanical structure. The air inlet drive component is installed in this groove, using an electric actuator, motor linkage, or servo motor, and achieves precise power output by receiving control signals. The air inlet panel 43 is connected to the drive component via a linkage or slide rail, and is directly driven by the drive component to rotate or translate, completing the opening and closing of the mounting groove opening. Simultaneously, an air inlet grille 42 is provided at the opening of the mounting groove, which can be a perforated mesh or louvered design, to guide airflow to the air inlet. This structure, through the linkage between the drive component and the panel, controls the air inlet opening while concealing the drive mechanism within the mounting groove, ensuring a clean appearance and improving dust prevention.

[0057] In specific embodiments, such as Figure 7 As shown, the driving component can adopt a gear and connecting rod structure to drive the air inlet panel 43 to move up and down to open and close the slot of the mounting groove. The driving component includes: two gear boxes 45, a first connecting rod 46 and a second connecting rod 47 corresponding to each gear box 45. The gear box 45 is installed in the mounting groove of the mounting bracket 41 and has a gear set and a drive motor inside. One end of the second connecting rod 47 is rotatably connected to the gear box 45 and is provided with a half-circle tooth groove to mesh with the gear in the gear box 45. Thus, the gear in the gear box 45 can drive the second connecting rod 47 to swing up or down. The upper end of the first connecting rod 46 is connected to the other end of the second connecting rod 47, and the lower end is connected to the air inlet panel 43, thereby driving the air inlet panel 43 to close up or open down.

[0058] like Figure 1 , 9 As shown, this utility model also proposes a bed-type air conditioner, including the aforementioned air duct 11 structure, and integrating a heat exchanger 3 that works in conjunction with the fan component 2, as well as an outdoor unit. The outdoor unit is circulated and connected to the heat exchanger 3 to deliver cooling or heating. The heat exchanger 3 is installed inside the air duct 11 near the airflow path of the fan component 2. Its structure is designed as a finned heat exchange module, which achieves heat exchange with the flowing air through refrigerant circulation. When the fan component 2 drives air to enter from the air inlet, the airflow first passes through the heat exchanger 3 for temperature regulation (cooling or heating), and then is guided through the air duct 11 to the air outlets at the head and foot of the bed. The close cooperation between the heat exchanger 3 and the air duct 11 structure ensures that the airflow makes full contact when passing through the heat exchange surface, improving heat exchange efficiency. By directly embedding the heat exchanger 3 into the airflow channel, and utilizing the directional airflow characteristics of the air duct 11 structure, the treated air accurately covers the user's sleeping area. The overall system achieves high-efficiency air circulation and temperature control functions in a compact space through the modular integration of air duct 11, fan and heat exchanger 3, while taking into account energy efficiency and quiet performance.

[0059] In addition, the structure proposed in this utility model makes good use of the large usable area of ​​the bed, embedding the indoor unit of the bed-type air conditioner, which not only saves space and achieves an aesthetic design, but also makes the bed more functional. Because the volume of the embedded air conditioner is much larger than that of ordinary indoor units, it can also make the heat exchange effect better and improve comfort.

[0060] Specifically, such as Figure 7 As shown, heat exchanger 3 is installed on the outlet side of cross-flow fan 21. Heat exchanger 3 adopts a split V-shaped structure, specifically composed of two sub-heat exchangers 3, one above the other. The two sub-heat exchangers 3 are symmetrically inclined about the outlet side of cross-flow fan 21, forming a V-shaped combination. The inclination angle of the sub-heat exchangers 3 is designed according to the airflow diffusion law, ensuring that the airflow discharged from cross-flow fan 21 naturally splits upon impacting the V-shaped opening, and then contacts the surfaces of the two sub-heat exchangers 3 for heat exchange. This split layout, by distributing the heat exchange area to two independent modules, avoids the problem of increased airflow resistance caused by an excessively large area of ​​a single heat exchanger 3, and also ensures that the airflow is evenly distributed to the upper and lower areas through the guiding effect of the V-shaped opening. The V-shaped structure formed by the inclined surfaces of the two sub-heat exchangers 3 points towards the center of cross-flow fan 21, capturing the airflow in the high-velocity core area. At the same time, the gradually expanding heat exchange surfaces on both sides guide the airflow smoothly to the outlet, achieving efficient heat absorption or release. This design improves heat exchange efficiency while reducing airflow disturbance caused by the large-area heat exchanger 3, ensuring that the bed air conditioner can maintain stable temperature control performance and low noise operation in different fan speed modes.

[0061] Specifically, such as Figure 1 , 8 As shown, a waterbed layer 5, which can be filled and drained, is laid on the bed body 1. The waterbed layer 5 is made of flexible waterproof material and has a closed circulating water chamber inside. The waterbed is in circulatory communication with the circulation component, which provides heating or cooling. The drain pipe 52 is located at the lowest point of the waterbed layer 5 and is equipped with a valve for periodic drainage, cleaning, or maintenance.

[0062] The waterbed's design allows for precise heat radiation to the body even in extremely low indoor temperatures. It not only provides a warm and comfortable sleeping environment during cold winters but also works in conjunction with air conditioning to further improve the overall indoor temperature. This dual-insulation method significantly enhances user comfort during winter.

[0063] Specifically, such as Figure 8 , 9As shown, the circulation assembly includes: a buffer water tank 51, which contains a coil connected to the liquid guide pipe of the outdoor unit for circulating water, used to control the water temperature in the buffer water tank 51 by the cooling or heating provided by the outdoor unit. The buffer water tank 51 is connected to the water bed supply pipe 54 and the water bed outlet pipe 55. Specifically, a water pump can be installed to continuously circulate the water in the water bed layer 5 and the water in the buffer water tank 51 to maintain the required temperature. A condensate drain pipe 56 is connected to the buffer water tank 51, allowing the buffer water tank 51 to collect condensate for use. The buffer water tank 51 is also connected to a water supply pipe to replenish water when the water level in the buffer water tank 51 is insufficient.
