Description

Ventilated sofa with cold and hot adjustment function TECHNICAL FIELD

[0001] The present application belongs to the technical field of sofa structure, and particularly relates to a ventilated sofa with cold and hot adjustment function. BACKGROUND

[0002] The biggest structural difference between the existing common ventilated sofa and the ordinary sofa is that the former has an air duct. The air duct matches an external or internal fan, thereby realizing basic ventilation effect.

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

[0004] For example, a single sofa with heating and ventilation function disclosed in a Chinese patent with the authorization announcement number CN218219685U and the authorization announcement date of 2023.01.06, comprises a sofa body, a heating and ventilation device is arranged in the backrest of the sofa body, the front surface of the backrest of the sofa body has a plurality of ventilation holes, the heating and ventilation device comprises a air distribution cavity, the air distribution cavity is connected with the plurality of ventilation holes, the air distribution cavity is connected with a heating device through a air supply pipe, the heating device is connected with a fan chamber through an air inlet pipe, a fan assembly is arranged in the fan chamber, the rear end of the fan chamber is connected with an air inlet through an air guide pipe, the air inlet is arranged at the rear end of the sofa body, and a plurality of dust screens are arranged in the air inlet.

[0005] The structure principle and advantages of the heating and ventilation sofa in the patent are as follows: the fan assembly is started to drive the airflow to flow, and the airflow is blown through the ventilation holes. When the temperature is high, the cooling effect can be achieved. When the temperature is low, the heating device is turned on to heat the air, and the hot air is blown out through the ventilation holes.

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

[0007] Firstly, the cold and hot adjustment structure is too complex, including a plurality of pipe bodies and a plurality of valves, which greatly increases the use and maintenance cost of the sofa.

[0008] Secondly, the fan assembly is directly arranged in the sofa backrest, and the internal space of the sofa backrest is very limited, so it is impossible to match a fan with large size and large wind power, which obviously limits the ventilation performance of the single sofa.

[0009] Therefore, it is urgent to provide a new type of high-performance cold and hot air conditioning sofa with a relatively simple cold and hot air conditioning structure and an external fan assembly. SUMMARY

[0010] The present application provides a ventilated sofa with cold and hot air conditioning function, which is capable of simplifying the complex air duct structure into an open hole bag unit by arranging a cushion soft package, an armrest plate, a fan, a support frame unit, an open hole bag unit, a ventilation pipe and an electric heating wire on a cushion plate, thereby not affecting the ventilation and heating effect and greatly reducing the use and maintenance cost of the ventilated sofa.

[0011] The technical scheme adopted by the present application to solve the above problems is: a ventilated sofa with cold and hot air conditioning function, which comprises a cushion plate, a cushion soft package, an armrest plate, a fan and a fan wire, and further comprises a support frame unit arranged on the 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 downwardly penetrating through the support frame unit and the cushion plate and used for connecting the fan, and an electric heating wire arranged in the open hole bag unit.

[0012] Further preferred technical scheme is that the support frame unit is arranged between the cushion soft package and the cushion plate.

[0013] Further preferred technical scheme is that the support frame unit is arranged inside the cushion soft package.

[0014] Further preferred technical scheme is that the support frame unit comprises a top plate for mounting the open hole bag unit, a pipe hole arranged on the top plate and used for penetrating through the ventilation pipe, and a support side plate arranged on the top plate.

[0015] Further preferred technical scheme is that the support frame unit further comprises an open hole bottom plate arranged on the support side plate and used for penetrating through the ventilation pipe.

[0016] Further preferred technical scheme is that the open hole bag unit comprises a bottom sheet arranged on the top plate, a top sheet arranged on the bottom sheet and used for mounting the electric heating wire by forming an internal cavity, an air inlet arranged on the bottom sheet and used for mounting the ventilation pipe, and an air outlet arranged on the top sheet.

[0017] Further preferred technical scheme is that the open hole bag unit further comprises two protruding sheets arranged on the bottom sheet and the top sheet respectively and used for fixing the electric heating wire wire.

[0018] Further preferably, the handrail plate is provided with a controller for connecting the electric heating wire and the fan wire and for adjusting the air volume and temperature.

[0019] Further preferably, the electric heating wire is arranged on the lower surface of the top sheet.

[0020] Further preferably, the fan is arranged at a position below the cushion plate. BRIEF DESCRIPTION OF DRAWINGS

[0034] The following description is merely preferred embodiments of the present application, and is not intended to limit the scope of the present application.

[0035] As shown in the accompanying drawings 1-8, a ventilated sofa with cold and hot adjustment function, the structure comprises a cushion plate 11, a cushion soft package 12, an armrest plate 13, a fan 14, and a fan wire 15, further comprises a support frame unit 1 arranged on the cushion plate 11, an open hole bag body unit 2 arranged on the upper surface of the support frame unit 1, a ventilation pipe 3 arranged on the open hole bag body unit 2, and downwardly penetrating the support frame unit 1 and the cushion plate 11, and used for connecting the fan 14, and an electric heating wire 4 arranged in the open hole bag body unit 2.

[0036] In the embodiment, the frame material of the cushion plate 11 and the armrest plate 13 is wood or metal, the main body material of the cushion soft package 12 is foamed material, and the fan 14 is a commercially available product, which is used for upward blowing, thereby realizing the 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 the main function is to support and protect the open hole bag body unit 2 and the electric heating wire 4, so as to ensure that the open hole bag body unit 2 is not easy to tear, and the electric heating wire 4 is not easy to be deformed or even broken.

[0038] In addition, the above-mentioned cold and hot adjustment function refers to the adjustable electric heating range of the electric heating wire 4. Therefore, the ventilated sofa does not have the function of blowing cold air without introducing additional refrigeration structure, and the "coldest" degree of the above-mentioned cold and hot adjustment function is that the "room temperature wind" is blown upward at the open hole bag body unit 2.

[0039] Finally, the electric heating wire 4 is directly installed in the open hole bag body unit 2, and the latter is connected downwardly with the fan 14 and is provided with upwardly open holes. Therefore, the whole cold and hot adjustment structure has the advantages of being relatively simple and practical. On the other hand, the ventilation pipe 3 penetrates downwardly through the cushion plate 11, so that the whole lower area of the cushion plate 11 is the effective installation space of the fan 14, which can be set to be relatively large in size, thereby finally ensuring that the ventilated sofa has strong ventilation effect.

[0040] The support frame unit 1 is arranged between the cushion soft package 12 and the cushion plate 11.

[0041] In the embodiment, the first installation mode of the support frame unit 1 together with the open hole bag body unit 2 is independent of the cushion soft package 12, which can be specifically referred to the accompanying drawing 2.

[0042] At this time, the self-thickness of the cushion soft package 12 can be set to be relatively small. The support frame unit 1 needs to consider the front aesthetic appearance and visual uniformity during use, one of the methods is that: the exposed side of the support frame unit 1 is provided with a covering material with the same color as the outer packaging material of the cushion soft package 12, or directly using the outer packaging material of the cushion soft package 12 to cover.

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

[0044] In this embodiment, it is the second installation mode of the support frame unit 1 with the open-pore bag body unit 2, which can be specifically referred to FIG. 1.

[0045] The matters needing attention in this installation mode are:

[0046] Firstly, the position of the support frame unit 1 in the cushion soft package 12 is relatively low, which avoids the hip of the sofa user from obviously touching the relatively hard support frame unit 1, and also makes the relatively upper position in the cushion soft package 12 can be provided with other new functional devices such as a massager 17;

[0047] Secondly, the bottom outer packaging material of the support frame unit 1 needs to reserve a wire hole for installing the heating wire 4;

[0048] Thirdly, when the cushion soft package 12 is taken out, the wire of the heating wire 4 needs to be avoided from being pulled, and during normal use, it also needs to be avoided from being pulled out, otherwise it is also easy to pull and break the above wire.

[0049] On the other hand, the support frame unit 1 has the following effects:

[0050] Firstly, if the support frame unit 1 is not provided, the open-pore bag body unit 2 is arranged alone between the cushion soft package 12 and the cushion plate 11, because the cushion plate 11 is relatively hard, the open-pore bag body unit 2 and the heating wire 4 are easy to be squeezed and torn or broken;

[0051] Secondly, still the open-pore bag body unit 2 is arranged alone between the cushion soft package 12 and the cushion plate 11, if there is no support frame unit 1, the wood or metal material of the cushion plate 11 cannot provide sufficient heat preservation effect, which greatly reduces the heat utilization rate of the heating wire 4;

[0052] Thirdly, if the support frame unit 1 is not provided, the open-pore bag unit 2 is provided alone in the cushion soft package 12, because the cushion soft package 12 is relatively soft, and the open-pore bag unit 2 and the heating wire 4 will be greatly bent and twisted due to the relatively large deformation of the cushion soft package 12 in the normal use process, which also causes the open-pore bag unit 2 to be easily torn and the heating wire 4 to be easily broken.

[0053] In summary, the main role of the support frame unit 1 is to support the open-pore bag unit 2 through its 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-pore bag unit 2, a pipe hole 102 provided on the top plate 101 and used for passing through the ventilation pipe 3, and a support side plate 103 provided on the top plate 101.

[0055] In this embodiment, the shape of the support frame unit 1 is a rectangular parallelepiped, and the thickness is obviously smaller than the length and width.

[0056] Among them, the number of support side plates 103 is 4, and the connection mode between the support side plates 103 and the top plate 101 is adhesion, gun nail connection or integral molding.

[0057] The support frame unit 1 further includes an open-pore bottom plate 104 provided on the support side plate 103 and used for passing through the ventilation pipe 3.

[0058] In this embodiment, the specific shape of the open-pore bottom plate 104 is a circular hole on a rectangular plate, which plays a role in strengthening the structure of the support frame unit 1, and the connection mode is consistent with that of the support side plate 103.

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

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

[0061] Wherein, the shape of the air inlet 203 is circular, and the position is relatively central, and when it is connected with the ventilation pipe 3, it is fully sealed and connected in the manner of the prior art.

[0062] The shape of the air outlet hole 204 is also circular, and its size is smaller than that of the air inlet 203, and the number is 4-20, which are uniformly and linearly arranged on the top sheet 202.

[0063] The open pocket unit 2 also includes two protruding sheets 205 arranged on the bottom sheet 201 and the top sheet 202 respectively, and used for fixing the heating wire 5.

[0064] In this embodiment, the two protruding sheets 205 are integrally formed with the bottom sheet 201 and the top sheet 202 respectively, and the upper and lower two protruding sheets 205 are fully bonded, and the glue used at this place is coated together with the one circle of glue of the above-mentioned rectangular frame shape, and the heating wire 5 is fixed and bonded between the upper and lower two protruding sheets 205.

[0065] The installation mode of the heating wire 5 has the advantage that the inevitable tear opening a occurs in the glue bonding area of the protruding sheet 205, rather than first occurring on the one circle of glue of the above-mentioned rectangular frame shape, which ensures that the sealed cavity between the bottom sheet 201 and the top sheet 202 is more stable.

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

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

[0068] Wherein, the specific structure of the armrest plate 13 is a main frame and an external skin, so that the heating wire 5 and the fan wire 15 can be inserted and installed, and the two are connected with the controller 6, and the controller 6 is connected with the power supply, so as to ensure that the electric heating function and the 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 plate 13.

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

[0071] In the embodiment, the electric heating wire 4 is connected with the lower surface of the top sheet 202 by high-temperature-resistant glue, the shape of the former can be reciprocating bending shape, and the former cannot block the air outlet hole 204.

[0072] On the other hand, if the electric heating wire 4 is adhered to the upper surface of the bottom sheet 201, the ventilation air flow cannot quickly and sufficiently take away the heat generated by the electric heating wire 4, and if the electric heating wire 4 is not adhered to the bottom sheet 201 and the top sheet 202, the electric heating wire 4 is easy to displace, twist and touch in the open hole bag body unit 2, which is not conducive to the stable heat generation of the electric heating wire 4. Therefore, the above-mentioned unique and optimal installation position is determined.

[0073] The fan 14 is arranged at a position below the cushion plate 11.

[0074] In the embodiment, the specific structure of the cushion plate 11 includes a cushion plate frame 11-1 and a snake-shaped spring 11-2. Therefore, the ventilation pipe 3 can pass downward, the fan wire 15 can pass upward, and finally the ventilation function can be effectively used.

[0075] Among them, the fan 14 can be placed on the ground for use, can be suspended by the ventilation pipe 3 for use, or can be installed on the inner side of the armrest plate 13, and the size specification can be relatively large, thereby realizing a strong enough ventilation effect.

[0076] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited to the above-mentioned embodiments, and various modifications can be made within the knowledge of ordinary skilled in the art without departing from the purpose of the application. These are not creative modifications, and as long as they are within the scope of the claims of the application, they are protected by the patent law.
