Description

Technical Field

[0001] The utility model belongs to the technical field of sofa structures, in particular to a ventilated sofa with a cooling and heating regulating function. Background Art

[0002] The biggest structural difference between common ventilated sofas and ordinary sofas is that the former has air ducts. These ducts can be matched with external or internal fans to achieve basic ventilation.

[0003] On the other hand, the above-mentioned heat and cold adjustment function refers to the fact that the ventilated sofa is also equipped with an electric heating structure. When the electric heating structure and the fan are both turned on, the ventilated sofa can provide a hot air blowing effect, and the electric heating intensity is adjustable, thereby providing the ultimate heat and cold adjustable ventilation effect.

[0004] For example, the Chinese utility model patent with authorization announcement number CN218219685U and authorization announcement date 2023.01.06 discloses a single sofa with heating and ventilation functions, including a sofa body, a heating and ventilation device is provided in the backrest of the sofa body, and the front surface of the backrest of the sofa body has a plurality of ventilation holes. The heating and ventilation device includes an air distribution cavity, which is connected to the plurality of ventilation holes. The air distribution cavity is connected to the heating device through an air supply pipe, and the heating device is connected to the front end of the fan chamber through an air inlet pipe. A fan assembly is installed in the fan chamber, and the rear end of the fan chamber is connected to the air inlet through an air duct. The air inlet is located at the rear end of the sofa body, and a plurality of dust nets are provided in the air inlet.

[0005] The structural principle and advantages of the heated and ventilated sofa in this utility model patent are generally as follows: Start the fan assembly to drive the air flow and blow air through the ventilation holes. When the temperature is high, it can play a role in cooling. When the temperature is low, turn on the heating device to heat the air and blow hot air out through the ventilation holes.

[0006] However, in actual use, the single sofa still has at least the following two shortcomings, which are also the technical problems to be solved by the present utility model, namely:

[0007] First, the heating and cooling structure is too complicated, including multiple pipes and valves, which will greatly increase the cost of using and maintaining the sofa.

[0008] Second, the fan assembly is directly set in the sofa backrest, and the internal space of the sofa backrest is very limited, so it cannot match a fan with larger size and stronger wind power, which obviously limits the ventilation performance of the single sofa.

[0009] Therefore, in summary, there is an urgent need for a new type of high-performance hot and cold regulating ventilation sofa product with a relatively simple hot and cold regulating structure and an external fan component. Utility Model Content

[0010] The utility model provides a ventilated sofa with a cooling and heating adjustment function. By arranging a soft seat cushion, an armrest board, a fan, a support frame unit, a perforated bag unit, a ventilation pipe, and an electric heating wire on a seat cushion board, the following can be achieved: 1. The existing common complex air duct structure is simplified into a perforated bag unit, which does not affect the ventilation and heating effects and greatly reduces the use and maintenance costs of the ventilated sofa; 2. The fan is externally arranged, and the size restriction on the fan is eliminated, thereby ensuring that the ventilated sofa can provide a greater ventilation intensity.

[0011] The technical solution adopted by the present invention to solve the above problems is: a ventilated sofa with hot and cold regulating functions, the structure of which includes a seat cushion plate, a soft seat cushion, an armrest plate, a fan, and a fan wire, and also includes a support frame unit arranged on the seat cushion plate, an open hole bag unit arranged on the upper surface of the support frame unit, a ventilation pipe arranged on the open hole bag unit and passing downward through the support frame unit and the seat cushion plate and used to connect to the fan, and an electric heating wire arranged in the open hole bag unit.

[0012] A further preferred technical solution is that the support frame unit is arranged between the seat cushion and the seat cushion plate.

[0013] A further preferred technical solution is that the support frame unit is arranged inside the seat cushion.

[0014] A further preferred technical solution is that the support frame unit includes a top plate for installing the open-hole bag unit, a pipe hole provided on the top plate and used for passing the ventilation pipe, and a supporting side plate provided on the top plate.

[0015] A further preferred technical solution is that the support frame unit further includes a perforated bottom plate provided on the support side plate and used for passing the ventilation pipe.

[0016] A further preferred technical solution is that the open-hole bag unit includes a bottom sheet arranged on the top plate, a top sheet with a side arranged on the bottom sheet and used to install the heating wire by forming an internal cavity, an air inlet arranged on the bottom sheet and used to install the ventilation pipe, and an air outlet arranged on the top sheet.

[0017] A further preferred technical solution is that the perforated bag unit further includes two protruding pieces respectively arranged on the bottom sheet and the top sheet and used for fixing the heating wire conductors.

[0018] A further preferred technical solution is that: a controller is provided on the armrest panel, which is connected to the heating wire wire and the fan wire and is used to adjust the air volume and temperature.

[0019] A further preferred technical solution is that the heating wire is arranged on the lower surface of the top sheet.

[0020] A further preferred technical solution is that the fan is arranged below the seat cushion. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0035] As attached Figure 1-8 As shown, a ventilated sofa with hot and cold regulating functions comprises a seat cushion 11, a seat cushion 12, an armrest 13, a fan 14, and a fan wire 15. It also comprises a support frame unit 1 arranged on the seat cushion 11, an open-hole bag unit 2 arranged on the upper surface of the support frame unit 1, a ventilation pipe 3 arranged on the open-hole bag unit 2, passing downward through the support frame unit 1 and the seat cushion 11, and used to connect to the fan 14, and an electric heating wire 4 arranged in the open-hole bag unit 2.

[0036] In this embodiment, the frame material of the seat cushion board 11 and the armrest board 13 is wood or metal, the main body material of the seat cushion soft bag 12 is foam material, and the fan 14 is a commercially available product, which is used to blow air upwards, thereby achieving basic sofa cushion ventilation effect.

[0037] Among them, the main body material of the support frame unit 1 is plastic or rubber, which has moderate elasticity and its main function is to support and protect the open hole bag unit 2 and the heating wire 4, to ensure that the open hole bag unit 2 is not easy to tear and the heating wire 4 is not easy to be greatly deformed or even broken.

[0038] In addition, the above-mentioned hot and cold adjustment function refers to the adjustable heating amplitude of the heating wire 4. Therefore, without the introduction of an additional cooling structure, the ventilated sofa does not have the function of blowing cold air. The "coldest" level of the above-mentioned hot and cold adjustment function is the "room temperature air" blown upward from the perforated bag unit 2.

[0039] Finally, the heating wire 4 is directly mounted within the perforated bag unit 2, which in turn is downwardly connected to the fan 14 and has upward-facing holes. This provides a relatively simple and practical cooling and heating mechanism. Furthermore, the ventilation duct 3 extends downward through the seat cushion 11, effectively allowing the fan 14 to be installed in the entire area below the seat cushion 11. This allows for a relatively large installation area, ultimately ensuring robust ventilation for the ventilated sofa.

[0040] The support frame unit 1 is disposed between the seat cushion 12 and the seat cushion plate 11 .

[0041] In this embodiment, the first installation method of the support frame unit 1 and the opening bag unit 2 is independent of the seat cushion 12. For details, please refer to the attached Figure 2 .

[0042] In this case, the thickness of the seat cushion 12 can be set to be relatively small. When the support frame unit 1 is in use, it is necessary to consider the aesthetics and visual consistency of the front surface. One method is to cover the exposed side surface of the support frame unit 1 with a covering material of the same color as the outer covering material of the seat cushion 12, or directly cover it with the outer covering material of the seat cushion 12.

[0043] The support frame unit 1 is arranged inside the seat cushion 12 .

[0044] In this embodiment, this is the second installation method of the support frame unit 1 and the perforated bag unit 2. For details, please refer to the attached Figure 1 .

[0045] Things to note about this installation method are:

[0046] First, the support frame unit 1 is positioned relatively low within the seat cushion 12, preventing the sofa user's buttocks from significantly contacting the relatively hard support frame unit 1. This also allows for the placement of other new functional devices, such as a massager 17, relatively high within the seat cushion 12.

[0047] Second, a wire hole for installing the heating wire 4 needs to be reserved on the bottom outer covering material of the support frame unit 1;

[0048] Third, when taking out the cushion soft bag 12, it is necessary to avoid pulling the wire of the heating wire 4. During normal use, it is also necessary to avoid it from sliding outward significantly, otherwise it is also easy to pull and break the above-mentioned wire.

[0049] On the other hand, the function of the support frame unit 1 is reflected in:

[0050] First, if the support frame unit 1 is not provided, and the perforated bag unit 2 is provided alone between the cushion 12 and the cushion board 11, then because the cushion board 11 is relatively hard, the perforated bag unit 2 and the heating wire 4 are easily squeezed, torn or broken;

[0051] Secondly, the perforated bag unit 2 is still arranged separately between the cushion soft bag 12 and the cushion board 11. Without the support frame unit 1, the cushion board 11 made of wood or metal cannot provide sufficient heat insulation effect, resulting in a significant reduction in the heat generation efficiency of the heating wire 4.

[0052] Third, if the support frame unit 1 is not provided, and the perforated bag unit 2 is provided alone in the seat cushion 12, then because the seat cushion 12 is relatively soft and its own deformation is relatively large during normal use, the perforated bag unit 2 and the heating wire 4 will be greatly bent and twisted, which will also cause the perforated bag unit 2 to be easily torn and the heating wire 4 to be easily broken.

[0053] In summary, the main function of the supporting frame unit 1 is to support the open hole bag unit 2 through its own appropriate hardness so that it is always in a flat and straight shape.

[0054] The support frame unit 1 includes a top plate 101 for mounting the open-hole bag unit 2 , a pipe hole 102 provided on the top plate 101 and used for passing the ventilation pipe 3 , and a supporting side plate 103 provided on the top plate 101 .

[0055] In this embodiment, the supporting frame unit 1 is in the shape of a cuboid, and its thickness is significantly smaller than its length and width.

[0056] There are four supporting side panels 103 , which are connected to the top panel 101 by bonding, nailing or integral molding.

[0057] The support frame unit 1 further includes a perforated bottom plate 104 provided on the support side plate 103 and used for passing the ventilation pipe 3 .

[0058] In this embodiment, the specific shape of the perforated bottom plate 104 is a rectangular plate with a circular hole, and its function is to strengthen the structure of the supporting frame unit 1 itself. Its connection method is consistent with that of the supporting side plates 103.

[0059] The open-hole bag unit 2 includes a bottom sheet 201 arranged on the top plate 101, a top sheet 202 whose side is arranged on the bottom sheet 201 and is used to install the heating wire 4 by forming an internal cavity, an air inlet 203 arranged on the bottom sheet 201 and used to install the ventilation pipe 3, and an air outlet 204 arranged on the top sheet 202.

[0060] In this embodiment, the bottom sheet 201 and the top sheet 202 are made of plastic and are rectangular in shape. They are connected and sealed by a circle of glue in the shape of a rectangular frame, so that after the ventilation airflow enters the air inlet 203, it will leave the air outlet 204 as much as possible, thereby avoiding large amounts of air leakage between the bottom sheet 201 and the top sheet 202.

[0061] The air inlet 203 is circular in shape and relatively centrally located. When connected to the ventilation pipe 3 , it is fully sealed in accordance with the prior art.

[0062] The air outlet holes 204 are also circular in shape and smaller in size than the air inlet holes 203 . The number of the air outlet holes 204 is 4-20 and they are evenly spaced on the top sheet 202 in a linear arrangement.

[0063] The perforated bag unit 2 further includes two protruding pieces 205 , which are respectively provided on the bottom sheet 201 and the top sheet 202 and are used to fix the heating wire 5 .

[0064] In this embodiment, the two protruding pieces 205 are integrally formed with the bottom piece 201 and the top piece 202 respectively, and the upper and lower protruding pieces 205 are fully bonded to each other. The glue used here is applied together with the circle of glue in the shape of the rectangular frame mentioned above to fix the heating wire 5 between the upper and lower protruding pieces 205.

[0065] The advantage of this installation method of the heating wire 5 is that the tearing hole a that is impossible to completely avoid occurs in the glue bonding area of ​​the protruding piece 205, rather than first occurring on the circle of glue in the rectangular frame shape mentioned above, ensuring that the sealed cavity between the bottom piece 201 and the top piece 202 is more stable.

[0066] The armrest plate 13 is provided with a controller 6 connected to the heating wire conductor 5 and the fan conductor 15 and used to adjust the air volume and temperature.

[0067] In this embodiment, the controller 6 is a commercially available product, and its principle may be to adjust the current on the heating wire 4 and the gear of the fan 14. Thus, the above-mentioned air volume and temperature adjustment functions are effectively achieved.

[0068] Among them, the specific structure of the armrest board 13 is the main frame and the outer skin, so the heating wire wire 5 and the fan wire 15 can be inserted and installed. The two are connected to the controller 6, and the controller 6 is connected to the power supply to ensure that the electric heating function and ventilation function of the sofa are effective and adjustable.

[0069] In addition, the controller 6 can be arranged on the inner side or the outer side of the armrest board 13.

[0070] The heating wire 4 is arranged on the lower surface of the top sheet 202 .

[0071] In this embodiment, the heating wire 4 is connected to the lower surface of the top sheet 202 via high temperature resistant glue. The shape of the former can be a reciprocating bend shape and cannot block the air outlet 204.

[0072] On the other hand, if the heating wire 4 is bonded to the upper surface of the bottom sheet 201, the ventilation airflow cannot quickly and fully carry away the heat generated by it. If the heating wire 4 is not bonded to either the bottom sheet 201 or the top sheet 202, the heating wire 4 is likely to shift, twist, or touch inside the open-hole bag unit 2, which is not conducive to its stable heat generation. Therefore, the above-mentioned unique and optimal installation position is determined.

[0073] The fan 14 is disposed below the seat cushion 11 .

[0074] In this embodiment, the specific structure of the seat cushion 11 includes a seat cushion frame 11-1 and a serpentine spring 11-2. Therefore, the ventilation pipe 3 can pass downward and the fan wire 15 can pass upward, ultimately ensuring that the ventilation function is effectively used.

[0075] The fan 14 can be placed on the ground for use, or can be suspended by the ventilation pipe 3 for use, or can be installed on the inner side of the armrest board 13. Its size can be relatively large, thereby achieving a sufficiently strong ventilation effect.

[0076] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications are possible within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. These modifications are non-inventive and are protected by patent law as long as they fall within the scope of the claims of the present invention.
