Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to an air duct structure of a bed-type air conditioner and a bed-type air conditioner. Background Art

[0002] Existing air conditioners are usually installed on the wall or window sill, occupying space area and affecting the overall beauty of the room. Moreover, the air outlet for air supply is generally at a high position in the room, which is easy to blow directly at people and affects the sleep quality. Specifically, the design of the air outlet position of traditional air conditioners has a spatial misalignment with the human activity area. When cold air or hot air blows vertically or obliquely from above to the human body, it is easy to cause a sudden change in local temperature, resulting in frequent turning over during sleep or waking up due to physical discomfort. If the air outlet direction is manually adjusted to avoid direct blowing, the air conditioner efficiency will be reduced, and the temperature balance needs to be achieved by heating / cooling the air in the whole room first, resulting in increased energy consumption and slow response speed.

[0003] Research shows that the human body is significantly more sensitive to air flow during sleep than in the waking state, and existing air conditioners can neither ensure local comfort nor avoid energy waste due to long-term operation. Although some products optimize the air supply range by adding swing blades or air guiding structures, their adjustment logic is still based on fixed programs or manual control. Therefore, how to improve the air supply efficiency and achieve non-intrusive air supply on the premise of avoiding direct blowing interference is still a difficult problem that has not been solved by the existing technology. Summary of the Invention

[0004] In order to solve the technical problems of low air supply efficiency and poor comfort of the air conditioner in the above-mentioned existing technology, the present invention provides an air duct structure of a bed-type air conditioner and a bed-type air conditioner.

[0005] The technical solution adopted by the present invention is as follows:

[0006] The present invention provides an air duct structure of a bed-type air conditioner, including: a bed body, an air inlet is provided at the bottom or side of the bed body, air outlets are provided at the head and / or tail positions of the bed body, an air duct communicating the air inlet with the air outlets is provided inside the bed body, and a fan component is provided in the air duct.

[0007] Further, the air outlet provided at the head of the bed body faces upward.

[0008] Further, the fan component includes: a cross-flow fan, and a wind guiding component covering the cross-flow fan and guiding air toward the head and / or tail of the bed.

[0009] Preferably, two cross-flow fans are provided, the two cross-flow fans are arranged at intervals, and the air inlet is located below the interval. The wind guiding component includes two wind guiding covers respectively covering the two cross-flow fans and guiding air toward the head and tail of the bed.

[0010] Further, first side plates and second side plates are respectively provided at positions corresponding to both ends of the cross-flow fan in the air duct, and a first rat guard blocking the front end of the connection between the first side plate and the second side plate and blocking the air outlet side of one of the cross-flow fans, and a second rat guard blocking the rear end of the connection between the first side plate and the second side plate and blocking the air outlet side of the other cross-flow fan.

[0011] Further, an air inlet panel component for opening and closing the air inlet is installed at the air inlet.

[0012] The air inlet panel component includes:

[0013] A mounting rack installed on an opening reserved on the bottom surface of the bed body. The mounting rack covers the bottom of the fan component and has the air inlet, and the mounting rack extends downward to form a mounting groove;

[0014] An air inlet driving component installed in the mounting groove;

[0015] An air inlet panel that drives to open and close the opening of the mounting groove through the air inlet driving component.

[0016] The present invention also provides a bed-type air conditioner, which is characterized in that it includes the above-mentioned air duct structure and a heat exchanger provided corresponding to the fan component.

[0017] Further, the heat exchanger is arranged on the air outlet side of the cross-flow fan, and the end face of the heat exchanger is V-shaped, and the opening direction of the V shape faces the cross-flow fan.

[0018] Further, it also includes a water bed layer laid on the bed body. The water bed layer is provided with a water discharge pipe, and the water bed layer is in circulating communication with a circulating component capable of providing cooling and heating.

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

[0020] 1. Through the special air duct, the sinking characteristic of cold air can be utilized, so as to avoid the user being directly blown by cold air, realizing "cold air does not blow on people", meeting the user's needs, avoiding various discomforts caused by direct blowing of cold air, and significantly improving the sleep quality and the user's experience.

[0021] And the floating characteristic of hot air can be utilized. The hot air rises from the bottom to form a warm air heat curtain wall, which can isolate the external cold air, thereby maintaining the internal environmental temperature and making the human body always feel warm and comfortable. This design not only improves the user experience, but also ensures the uniform distribution of the indoor temperature, truly realizing the beneficial effect of a constant temperature and comfortable home environment.

[0022] 2. The design of combining a water bed with a heating pipe can achieve precise heat radiation to the human body when the indoor temperature is extremely low. It not only provides a warm and comfortable sleeping environment for users in the cold winter, but also works in coordination with the air conditioner to further improve the overall indoor environmental temperature.

[0023] 3. By making good use of the large available area of the bed, an in-bed air conditioner indoor unit is embedded, which not only saves space and achieves an aesthetic design, but also diversifies the functions of the bed. Since the volume of the embeddable air conditioner is much larger than that of a common indoor unit, it can also make the heat exchange effect better and improve comfort.

[0024] 4. A double cross-flow fan is adopted, and the air flows in from the periphery of the air inlet panel. Without affecting the air inlet flow, the special structural design can absorb and reflect part of the noise of the fan system, reducing the total noise value, reducing noise pollution, and also facilitating the embedding of the air conditioner into the bed body.

[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention 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 only used to explain the present invention, and are not used to limit the present invention.

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

[0046] In the heating mode of traditional air conditioners, hot air naturally rises due to its lower density, resulting in a significantly higher temperature at the top of the room than in the human activity area (such as the bed surface or seat height), forming an obvious "hot head and cold feet" phenomenon. Experimental data shows that when the air conditioner operates for 30 minutes, the indoor vertical temperature difference can reach 5°C to 8°C, far exceeding the human comfort temperature difference range. Especially in the winter sleep scenario, insufficient heating of the feet can easily lead to poor blood circulation and a cold body feeling, while overheating of the head may cause problems such as hot flashes and night sweats. Although some air conditioners try to bridge the temperature difference by adding a circulation fan or a wind deflector, such solutions can only dilute the local temperature difference by expanding the air supply range and cannot fundamentally solve the physical property of hot air floating. In addition, continuously operating the air conditioner to reduce the temperature difference will significantly increase energy consumption, and the temperature fluctuations caused by frequent start-stop further exacerbate human discomfort.

[0047] In response to this, asFigure 1 , 2 As shown in 2 , the present invention provides a structure of a bed - type air - conditioning duct 11, which includes: a bed body 1 and a fan component 2. Among them: The bed body 1 specifically includes a bed frame and a headboard. The headboard is connected to the end of the bed frame and extends upward. An air inlet is provided at the bottom or side of the bed frame for introducing external air. In this embodiment, the case where the air inlet is provided at the bottom is taken as an example for illustration. The position of the air inlet of the bed body 1 can be selected at the bottom or side according to the actual installation environment to facilitate adaptation to different room layouts; Air outlets are provided at the top of the headboard and the end face of the foot of the bed body 1 to achieve directional discharge of air (it should be noted that the air outlet can also be provided only at the top of the headboard, or only at the foot of the bed). A duct 11 that integrates and connects the air inlet and the air outlet is provided inside the bed body 1. The path of the duct 11 is designed as a smooth air flow channel according to the structure of the bed body 1 to ensure that air enters from the air inlet, undergoes internal circulation, and finally is sent out from the air outlet, and can concentrate on blowing air to the user's sleeping area or form a surrounding - type air flow circulation. The fan component 2 is installed inside the duct 11, and its function is to drive the air to form a continuous air flow channel between the air inlet and the air outlet. The fan component 2 generates a pressure difference through directional rotation, pushing air to be inhaled from the air inlet, transported through the duct 11, and evenly discharged from the air outlet.

[0048] This structure realizes the directional flow of air inside the bed body 1 by setting the air outlets at the head and foot of the bed body 1 respectively. Compared with the long - distance air - blowing method of traditional air conditioners, the duct 11 structure of the bed - type air conditioner can more accurately control the air flow direction and improve the temperature uniformity and comfort of the local area. As Figure 4 shown, in the heating mode, using the floating characteristic of hot air, the hot air rises from the bottom to form a hot air curtain, which can isolate the cold air outside, thereby maintaining the internal environmental temperature and making the human body always feel warm and comfortable. This design not only improves the user experience but also ensures the uniform distribution of indoor temperature, truly achieving the beneficial effect of a constant - temperature and comfortable home environment. As Figure 5 shown, in the cooling mode, using the sinking characteristic of cold air, it can also prevent the cold air from directly blowing on the human body and quickly cool down.

[0049] In a further embodiment, as Figure 4 , 5 shown, the air outlet provided at the head position of the bed body 1 is arranged upward. This design makes the air discharged upward from the head of the bed, forming a vertically upward air flow. The upward - facing air outlet can effectively prevent the air flow from directly blowing on the user's head or body, thereby improving the comfort and health of use. At the same time, this air - blowing direction is convenient for the air to diffuse in the indoor space, promoting the overall air circulation, especially suitable for scenarios where a uniform temperature distribution is required. The upward design of the air outlet is seamlessly connected to the duct 11 inside the bed body 1, ensuring that the air flow remains smooth and stable during output, and further enhancing the operating efficiency of the duct 11 structure.

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

[0051] Specifically, as Figure 5 、 6 、shown in Fig. 7, the fan component 2 includes a cross-flow fan 21 and a wind guiding component. The cross-flow fan 21 is installed in the air duct 11 inside the bed body 1, adopting a multi-blade axial structure, and forming a stable linear air flow through high-speed rotation. Specifically, both ends of the cross-flow fan 21 face both sides of the bed body 1. The wind guiding component covers the outside of the cross-flow fan 21, and its inner wall has an arc-shaped or air deflector structure, which can direct the air flow towards the head or foot of the bed according to requirements. The cooperative design of the wind guiding component and the cross-flow fan 21 realizes the control of the air flow direction and avoids disorderly diffusion. When it is necessary to supply air to the head of the bed, the air deflector surface of the wind guiding component concentrates and guides the air flow to the air outlet at the head of the bed; similarly, the structure of the wind guiding component can also be set to supply air to the foot of the bed directionally or supply air to both the head and foot of the bed synchronously according to needs. This design reduces the turbulent loss by optimizing the air flow path, improves the fan efficiency, and at the same time supports flexible switching of the wind direction to meet the cooling or heating requirements of different sleeping areas.

[0052] In a preferred embodiment, the fan component 2 adopts a layout of two cross-flow fans 21. The two cross-flow fans 21 are arranged at intervals in the horizontal direction, and the gap between them is directly opposite to the position of the air inlet, so that external air can evenly enter the fan suction area through the air inlet below the gap. The wind guiding component includes two independent wind guiding covers 22, and each wind guiding cover 22 covers the cross-flow fan 21 at the corresponding position. The front wind guiding cover 22 near the head of the bed guides the air flow towards the head of the bed through the inner wall arc-shaped surface, and the rear wind guiding cover 22 near the foot of the bed guides the air flow to the foot of the bed area through the reverse air deflector structure. The arrangement of the two cross-flow fans 21 in cooperation with the split wind guiding covers 22 forms a directional split transmission path: the front cross-flow fan 21 outputs air flow towards the head of the bed through the front wind guiding cover 22, and the rear cross-flow fan 21 transports air flow towards the foot of the bed through the rear wind guiding cover 22. This design realizes independent air supply at both ends of the bed body 1 through dual-channel air flow separation. At the same time, the layout with the air inlet below the gap between the two fans shortens the air entry path, reduces the air inlet 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 at both ends of the cross-flow fan 21 inside the air duct 11 as a longitudinal support frame. The first side plate 24 and the second side plate 25 are installed with a first rat guard 26 at the front-end connection. This rat guard is located on the air outlet side of the front cross-flow fan 21 and is made of a metal mesh or a perforated plate. While blocking foreign objects from entering, it keeps the air flow unobstructed. Similarly, a second rat guard 27 is provided at the connection of the tails of the first side plate 24 and the second side plate 25 to protect the air outlet side of the corresponding rear cross-flow fan 21. The rat guards and the side plates form a closed protection structure, which not only prevents dust and small animals from flowing back into the fan interior from the air outlet end, but also avoids the direct exposure of the blades, thus eliminating potential safety hazards. The combined design of the side plates and the rat guards also enhances the rigid support inside the air duct 11, ensuring the structural stability of the double cross-flow fan 21 during high-speed operation, while maintaining the integrity of the air flow guiding path.

[0054] In a specific embodiment, the air inlet is configured with an openable and closable air inlet panel component 4. This component is installed on the bed body 1, and its air inlet panel 43 can be specifically connected through a connecting rod or a slide rail structure, and can be manually or automatically adjusted to open and close according to requirements. When the air inlet panel 43 is in the closed state, it effectively isolates external dust and foreign objects from entering; in addition, an antibacterial coating or an electrostatic adsorption layer can be integrated on the panel surface to perform primary purification of the incoming air. This design not only improves the air flow controllability during equipment operation, but also facilitates regular cleaning and maintenance, and closes the panel during non-use periods.

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

[0056] The mounting frame 41 is fixed at the bottom opening of the bed body 1, and its structure covers the area below the fan component 2, that is, it serves as a cover below the fan component 2, and an opening forming the air inlet is provided at the bottom. The mounting frame 41 extends downward to form a sunken mounting groove for accommodating the driving component and hiding the internal mechanical structure. The air inlet driving component is installed in this groove and adopts driving forms such as an electric push rod, a motor connecting rod, or a servo motor, and realizes precise power output by receiving a control signal. The air inlet panel 43 is connected to the driving component through a connecting rod or a slide rail, and is directly driven by the driving component to rotate or translate to complete the opening and closing action of the opening of the mounting groove. At the same time, an air inlet grille 42 is provided at the opening of the mounting groove, which can specifically adopt a perforated grid or a louver design for guiding air to the air inlet. This structure realizes the control of the air inlet opening degree through the linkage of the driving component and the panel, and hides the driving mechanism in the mounting groove, which not only ensures a clean appearance but also improves the dust-proof effect.

[0057] In a specific embodiment, as Figure 7As shown, the driving component can use a gear-coordinated connecting rod structure to drive the air inlet panel 43 to move up and down to open and close the notch of the mounting slot. 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 slot of the mounting frame 41, and a gear set and a driving motor are provided inside. One end of the second connecting rod 47 is rotatably connected to the gear box 45, and a half-circle tooth groove is provided to mesh with the gear in the gear box 45, so that the gear in the gear box 45 can drive the second connecting rod 47 to swing upward or downward, the upper end of the first connecting rod 46 is transmission-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 upward or open downward.

[0058] like Figure 1 , 9 As shown, the present invention also proposes a bed-type air conditioner, which includes the above-mentioned air duct 11 structure, and integrates a heat exchanger 3 that works in coordination with the fan component 2, and an external unit part, and the external unit circulates and connects the heat exchanger 3 to transport cold or heat. The heat exchanger 3 is installed on the air flow path near the fan component 2 inside the air duct 11, and its structure is designed as a fin-type heat exchange module, which realizes heat exchange with the flowing air through the refrigerant cycle. When the fan component 2 drives the air to enter from the air inlet, the air flow first passes through the heat exchanger 3 for temperature adjustment (cooling or heating), and then is guided to the air outlets at the head and foot of the bed through the air duct 11 for delivery. The close cooperation between the heat exchanger 3 and the air duct 11 structure ensures that the air flow is fully in contact with the heat exchange surface when passing through the heat exchange surface, thereby improving the heat exchange efficiency. By directly embedding the heat exchanger 3 into the air flow channel and utilizing the directional air supply characteristics of the air duct 11 structure, the treated air accurately covers the user's sleeping area. The overall system realizes high-efficiency air circulation and temperature control functions in a compact space through modular integration of the air duct 11, the fan and the heat exchanger 3, taking into account both energy efficiency and quiet performance.

[0059] In addition, the structure proposed in the present invention makes good use of the large usable area of ​​the bed and embeds the bed-type air-conditioning indoor unit, which not only saves space and achieves a beautiful design, but also diversifies the functions of the bed. Because the volume of the embeddable air conditioner is much larger than that of an ordinary indoor unit, it can also make the heat exchange effect better and improve comfort.

[0060] Specifically, Figure 7As shown, the heat exchanger 3 is installed on the air outlet side of the cross-flow fan 21. The heat exchanger 3 adopts a split V-shaped structure, which is specifically composed of two upper and lower sub-heat exchangers 3. The two sub-heat exchangers 3 are symmetrically and obliquely arranged with the air outlet side of the cross-flow fan 21 as the central axis, forming a combined shape with a V-shaped end face. The inclination angle of the sub-heat exchanger 3 is designed according to the air flow diffusion law to ensure that the air flow discharged from the cross-flow fan 21 is naturally split when hitting the V-shaped opening, and respectively adheres to the surfaces of the upper and lower sub-heat exchangers 3 for heat exchange. This split layout disperses the heat exchange area into two independent modules, which not only avoids the problem of increased air flow resistance caused by an overly large single heat exchanger 3, but also evenly distributes the air flow to the upper and lower regions 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 has its tip facing the center of the cross-flow fan 21, capturing the air flow in the high-velocity core area. At the same time, the gradually expanding heat exchange surfaces on both sides guide the air flow to smoothly transition to the air outlet, achieving efficient heat absorption or release. This design improves the heat exchange efficiency while reducing the air flow disturbance caused by a large-area heat exchanger 3, ensuring that the bed-type air conditioner can maintain stable temperature control performance and low-noise operation in different wind speed modes.

[0061] Specifically, as Figure 1 , 8 shown, a water bed layer 5 that can be filled with and drained of water is laid on the bed body 1. The water bed layer 5 is made of a flexible waterproof material and is internally provided with a closed circulating water cavity. The water bed is in circulating connection with the circulation component and is heated or cooled through the circulation component. The drain pipe 52 is arranged at the lowest part of the water bed layer 5 and is equipped with a valve for regular drainage cleaning or maintenance.

[0062] The setting of the water bed can achieve precise heat radiation to the human body when the indoor temperature is extremely low. It not only provides a warm and comfortable sleeping environment for users in the cold winter, but also works in coordination with the air conditioner to further improve the overall indoor environmental temperature. Through this dual heat preservation method, the comfort of users in winter home life is significantly improved.

[0063] Specifically, as Figure 8 , 9 shown, the circulation component includes: a buffer water tank 51. A coil is provided in the buffer water tank 51, and the coil is connected in a loop to the liquid guide pipe of the external unit to control the water temperature in the buffer water tank 51 through the cold or heat provided by the external unit. The buffer water tank 51 is connected to the water bed water supply pipe 54 and the water bed water outlet pipe 55. Specifically, a water pump can be set 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. The condensate drain pipe 56 is connected to the buffer water tank 51, enabling the buffer water tank 51 to collect and utilize the condensate. At the same time, the buffer water tank 51 is also connected to the water supply pipeline to replenish water when the water volume in the buffer water tank 51 is insufficient.
