Description

Technical Field

[0001] The present invention relates to a temperature control system for a seat, and more particularly to an air-conditioned seat and an air-conditioning system for the seat, which can enable airflow to flow toward the seat and achieve cooling and heating functions. Background Art

[0002] Ambient temperature control in daily life or workspaces is usually achieved by stabilizing the air temperature, such as in an entire room, office, or a single enclosed area. Traditional wall-mounted and cabinet units are mainly used to remove heat or moisture from the entire room, but they have the following problems:

[0003] (1) When heating, hot air cannot sink effectively, and a large amount of heat accumulates above the human activity area (space above 1.8m), causing heating discomfort and heat waste;

[0004] (2) The cold air jet is too concentrated, and the blowing feeling is too strong, which can easily cause air conditioning disease; the windless air conditioning products on the market are essentially to achieve energy re-release by blocking the air flow, which will inevitably lead to a significant reduction in air volume and cooling capacity;

[0005] (3) Even with normal air conditioning, in hot weather, the back and other pressure points of the seated person will continue to sweat while sitting. In winter, it is very desirable to have a seat that can be heated quickly to facilitate the improvement of the seated person's comfort.

[0006] (4) The wall-mounted or cabinet air conditioner in the living room is large in size, and many families hope that the air conditioner will not occupy the limited indoor space.

[0007] Due to the above reasons, there is an urgent need for a seat with air conditioning and a seat air conditioning system to solve the problem of quickly and evenly cooling the entire house in hot weather; in the winter when the temperature is lower, the foot space can heat up quickly, allowing more heat to be concentrated in the human activity area, reducing heat loss in non-human activity areas, improving the comfort level of the entire house while significantly reducing energy consumption, thereby achieving energy-saving effects. Summary of the Invention

[0008] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an air-conditioned seat and seat air-conditioning system.

[0032] The embodiments of the present invention are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0033] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples.

[0034] It should be noted that, for the sake of convenience, unless otherwise stated, the directions or positional relationships indicated by the following directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are all based on the first-person perspective of a person sitting on the seat, where "front" is defined in front of the seated person, "back" is defined in the direction of the seated person's back, "left" is defined in the direction of the seated person's left hand, and "right" is defined in the direction of the seated person's right hand. The directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself. Figures 1 to 6 A seat with air conditioning according to an embodiment of the present invention is described.

[0035] like Figure 1As shown, the air-conditioned seat includes a seat body 10 having a seat cushion 11 and a seat back 12. The seat cushion 11 supports the occupant's thighs and buttocks, while the seat back 12 supports the occupant's spine. Preferably, the seat cushion 11 and the seat back 12 are formed of seat pads that elastically deform by supporting the occupant on their front sides. The seat pads are made of an elastic component such as polyurethane foam.

[0036] like Figures 1 to 3 The air-conditioned seat in a preferred embodiment of the present invention also includes an air flow passage 40 extending through the seat body 10 to ensure smooth airflow, an air inlet passage 20 and an air outlet 30 connected to the air flow passage 40. The air inlet passage 20 is an air flow opening located on the bottom surface of the seat body 10 and switchably connected to the air flow passage 40. The air outlet 30 includes at least one air flow opening located on the side of the seat cushion 11 and / or the seat back 12. Furthermore, the air blower 50 is located within the air flow passage 40 to provide power for the air flow. Thus, under the action of the air blower 50, external air enters the air flow passage 40 from the air inlet passage 20, is guided and rectified by the air flow passage 40, and then flows out of the air outlet 30. This directs the heated or cooled air flow to remove heat or moisture from the entire room, achieving downward delivery of hot air for rapid heating during heating, and multi-dimensional cooling of the entire room during cooling, thereby improving cooling efficiency, significantly improving overall comfort, and achieving energy savings.

[0037] In some embodiments of the present invention, the air inlet passage 20 includes at least two groups of air inlets to ensure that there is sufficient air intake. Figure 2 and Figure 3 As shown, the air inlet passage 20 includes a length direction ( Figure 1 A first air inlet 21 and a second air inlet 22 are provided extending along the bottom surface of the seat body 10 (in the x-direction). The first air inlet 21 and the second air inlet 22 are spaced apart from each other and arranged on the bottom surface of the seat body 10. To facilitate temperature control of air entering the air flow channel 40, a movable baffle 23 is provided at the connection between the air inlet passage 20 and the air flow channel 40. The movable baffle 23 can be moved and switched between the first air inlet 21 and the second air inlet 22.

[0038] In some embodiments of the present invention, the air outlet 30 includes at least two groups of air flow channels for air outlet or air intake, so as to achieve multi-dimensional overall cooling of the whole house and / or local heating. Figure 3 As shown, the air outlet 30 includes a first air outlet 31 and at least two groups of second air outlets 32. The first air outlet 31 is opened on the side of the front end of the seat cushion 11, that is, in the width direction of the seat body 10 ( Figure 1In the direction opposite to y in the figure), the second air supply port 32 is provided on the side surface of the rear end side of the seat back 12. That is, the second air supply port 32 is provided on the side surface of the back of the seat back 12. Such a layout design ensures that after the air enters the air flow channel 40 through the air inlet passage 20, it is divided into two streams therein, one part of the air flow is blown out by the first air supply port 31, and the other part of the air flow is blown out by the second air supply port 32. In view of the positions of the first air supply port 31 and the second air supply port 32, it is beneficial to adjust the direction of the blown air flow. For example, by adjusting the position of the opening of the first air supply port 31, the hot air blown out of the first air supply port 31 can be directed downward, achieving the effect of quickly warming the feet.

[0039] In summary, the air supply outlet provided in the embodiment of the present invention can realize the downward delivery of hot air during heating, achieving the effect of directly warming the feet, which greatly improves its effect and performance, and reduces heat loss in non-human activity areas, with good energy-saving effects.

[0040] In some embodiments of the present invention, the air flow channel 40 can be various suitable mechanisms, such as Figure 3 As shown, the airflow passage 40 includes a first channel 41 and a second channel 42, wherein the first channel 41 is connected to the first air outlet 31, and the second channel 42 is connected to the second air outlet 32. Therefore, after the air enters the airflow passage 40 through the air inlet passage 20, part of the airflow can be blown out through the first air outlet 31 through the first channel 41, and the other part of the airflow can be blown out through the second air outlet 32 ​​through the second channel 42.

[0041] In a preferred embodiment of the present invention, the connection structure between the first channel 41 and the first air outlet 31 is substantially the same as the connection structure between the second channel 42 and the second air outlet 32. Therefore, as a representative example of the connection structure between the first channel 41 and the first air outlet 31, please refer to Figures 3 to 6 The connection structure between the first duct 41 and the first air outlet 31 will be described.

[0042] In order to improve the comfort of the air blown out from the air outlet 30, reduce the energy loss of the air flow in the air flow channel, and improve the energy efficiency ratio, the flow area of ​​the first channel 41 and the second channel 42 are set to be gradually changed. Preferably, the cross section of the first channel 41 is set to have a gradually increasing flow area from the air outlet of the first wind wheel 51, and the cross section of the second channel 42 is set to have a gradually increasing flow area from the air outlet of the second wind wheel 52. Specifically, Figure 3 As shown, the first channel 41 includes a first volute tongue 411 and a first volute case 412 arranged at the connection between the first channel 41 and the first air supply port 31. The first volute case 412 and the first volute tongue 411 are inclined upward and arranged at intervals to form an air flow channel with a gradually increasing flow area, thereby reducing the energy loss of the air flow passing through the first air supply port 31 and improving the energy efficiency ratio.

[0043] Preferably, the contour of the connecting end of the first volute tongue 411 and the first air outlet 31 protrudes inward to form a tip that can split the airflow, and the connecting end of the first volute 412 and the first air outlet 31 has an inverse parabolic contour. The tip that can split the airflow is formed by the first volute tongue 411 to prevent part of the gas from circulating in the first volute 412. When the airflow at the channel outlet of the first wind wheel 51 passes near the first volute tongue 411, the tip of the first volute tongue 411 divides it into two: most of the airflow flows along the channel to the first air outlet 31; a small part of the airflow flows back to the first volute 412 through the gap between the first volute tongue 411 and the impeller, and after rotating for one circle with the airflow sent out by the first wind wheel 51 in the first volute 412, it returns to the first volute tongue 411 to participate in a new diversion.

[0044] Preferably, the normal line of the shortest distance between the first volute 411 and the first volute 412 (i.e., the perpendicular line to the line connecting the shortest distance between the first volute 411 and the first volute 412) is set at an angle β with the horizontal plane, and β is 10°-60°. By limiting the normal line of the shortest distance between the first volute 411 and the first volute 412 to form an angle β with the horizontal plane, the problem of surging, reduced air volume, and increased noise caused by the suction force of the first wind wheel 51 being mainly concentrated directly above the first wind wheel and the airflow hitting the inner wall of the airflow channel 40 and reacting on the first wind wheel 51 is effectively solved. At the same time, it also avoids the problem of the first air supply port 31 having an excessively large air supply angle, which affects the comfort in the heating state, and can achieve ground-level air supply in the heating state, improving the comfort in the heating state.

[0045] Based on the same principle, Figure 4 As shown, the second channel 42 includes a second volute tongue 421 and a second volute case 422 arranged at the connection between the second channel 42 and the second air supply port 32. The second volute case 422 and the second volute tongue 421 are inclined upward and arranged at intervals to form an air flow channel with a gradually increasing flow area.

[0046] Preferably, the contour of the connecting end of the first volute tongue 421 and the second air outlet 32 ​​protrudes inward to form a tip that can split the airflow, and the connecting end of the first volute 422 and the first air outlet 31 presents a reverse parabolic contour.

[0047] Preferably, the normal of the shortest distance between the second volute tongue 421 and the second volute 422 (i.e., the perpendicular line to the line connecting the shortest distance between the second volute tongue 421 and the second volute 422) is set at an angle γ with the horizontal plane, and γ is 35°-85°.

[0048] The blower 50 can be of various suitable structures, such as Figure 3As shown, the blower 50 includes at least two air supply components, which are disposed within the inner cavity of the airflow channel 40 to drive or adjust the direction of the airflow entering the airflow channel 40. Specifically, in a preferred embodiment of the present invention, the blower 50 includes a first blower wheel 51 and a second blower wheel 52 embedded in the airflow channel 40. The first blower wheel 51 is located at the channel end near the first air supply port 31, and the second blower wheel 52 is located at the channel end near the second air supply port 32. Preferably, the first blower wheel 51 and the second blower wheel 52 are crossflow blowers.

[0049] In some embodiments of the present invention, Figure 3 As shown, in order to strengthen the temperature control of the air flow and improve the cooling or heating efficiency of the air flow, a heat exchanger 60 is also provided in the inner cavity of the air flow channel 40. The heat exchanger 60 is arranged along the length direction of the seat body 10 ( Figure 1 (x-direction in the figure); preferably, the heat exchanger 60 is positioned in the airflow channel 40 near the air inlet duct 20 to increase the duration of air flow through the air inlet duct 20, further improving heating or cooling efficiency. Optionally, the heat exchanger 60 can be customized to suit user needs. A large number of heat exchangers 60 rows can improve the cooling and heating capabilities of the air conditioner and increase its energy efficiency. A small number of heat exchangers 60 rows can be used for low-energy-efficiency models; a large number of heat exchanger rows can be used for high-energy-efficiency models. Preferably, there are 1-4 rows of heat exchangers 60.

[0050] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, in order to prevent the condensed water formed by the heat exchanger 60 from flowing to the floor when the heat exchanger 60 is in the cooling state, a water receiving tray 70 is further provided at the bottom end of the heat exchanger 60. The water receiving tray 70 is provided along the length direction of the seat body 10 ( Figure 1 (x-direction in the figure). Preferably, to reduce the possibility of condensed water on the surface of heat exchanger 60 dripping while flowing along the surface of heat exchanger 60, the heat exchanger 60 is arranged at an angle α with the horizontal plane, α being 45°-135°. Within this angle range, condensed water can effectively flow to the drain pan during cooling, and the number of heat exchangers can be maximized, thereby improving the energy efficiency of the entire unit.

[0051] The working principle of the air-conditioned seat provided by the present invention is as follows:

[0052] During winter heating, the first wind wheel 51 rotates and the second wind wheel 52 does not move. The movable baffle 23 moves to the left to prevent the air from entering from the first air inlet 21 and being directly discharged from the first air outlet 31 without passing through the heat exchanger 60. When the first wind wheel 51 rotates, air can enter from the second air inlet 22 and the second air outlet 32 ​​at the bottom. The two air flows converge in front of the heat exchanger 60 and then pass through the heat exchanger 60 to achieve the effect of rapid temperature increase. Under the action of the first wind wheel 51, the hot air is discharged along the first air outlet 31. Since one side of the discharged hot air flow is close to the floor, it is a restricted attached jet. A longer attached jet length can be formed in the room, thereby making the temperature at the bottom of the room higher and achieving a warm foot effect. Since a large amount of heat is in the range below 1.8m above the human activity area, compared with traditional wall-mounted air conditioners, it can prevent a large amount of hot air from accumulating in the space above the human activity area (1.8m-2.8m), reducing heat loss in non-human activity areas, thereby reducing energy consumption and achieving energy-saving effects.

[0053] During summer cooling, the first wind wheel 51 does not move, and the second wind wheel 52 rotates. The movable baffle 23 moves to the right to prevent the wind from entering from the second air inlet 22 and being sent out directly from the second air outlet 32 ​​without passing through the heat exchanger 60. When the second wind wheel 52 rotates, air can enter from the first air inlet 21 at the bottom and the first air outlet 31 on the front side. The two winds converge in front of the heat exchanger 60 and then pass through the heat exchanger 60 to achieve the effect of quickly lowering the temperature. After the cold air passes through the second wind wheel 52 and does work, it is sent out along the air duct. The second air outlet 32 ​​is set to discharge air from multiple sides to improve the uniformity of the air outlet, reduce the feeling of blowing, and cool the room as a whole from multiple dimensions to improve cooling comfort.

[0054] Another embodiment of the present application provides a seat air conditioning system, comprising a control assembly for receiving and executing external commands and the air-conditioned seat of the preferred embodiment described above. The control assembly is electrically connected to the air-conditioned seat. Specifically, the control modules for the air inlet duct 20, the blower 50, and the heat exchanger 60 are each electrically connected to the control assembly.

[0055] The control component conveniently receives and executes external commands to control the seat's air conditioning system. For example, commands from a dedicated remote control, an app on a smart terminal, or other control device control the air inlet duct 20, blower 30, and heat exchanger 60 through the control component, enabling or disabling cooling and heating modes, as well as switching between different modes.

[0056] The seat air conditioning system according to the embodiment of the present invention can realize two different operating modes under different cooling and heating requirements.

[0057] In normal mode:

[0058] Heating: The first wind wheel 51 rotates, and the second wind wheel 52 does not move. The movable baffle 23 moves to the left to prevent the air from entering from the first air inlet 1 and being directly discharged from the first air outlet 31 without passing through the heat exchanger 60. When the first wind wheel 51 rotates, air can enter from the second air inlet 22 and the second air outlet 32 ​​at the bottom. The two air streams converge in front of the heat exchanger 60 and then pass through the condenser to achieve the effect of rapid temperature increase. After the hot air passes through the wind wheel and performs work, it is discharged through the first air outlet 31;

[0059] Cooling: The first impeller 51 remains stationary, while the second impeller 52 rotates. The movable baffle 23 moves rightward to prevent air from entering the second air inlet 22 and being discharged directly from the second air supply 32 without passing through the heat exchanger 60. When the second impeller 52 rotates, air enters from the bottom first air inlet 21 and the front first air supply 31. These two air streams merge before the heat exchanger 60, then pass through it, rapidly reducing the temperature. After passing through the second impeller 52, the cool air is discharged through the second air supply 32 duct.

[0060] In special mode:

[0061] Heating: The first wind wheel 51 remains stationary, while the second wind wheel 52 rotates. The movable baffle 23 moves to the right to prevent air from entering the second air inlet 22 and being directly discharged from the second air outlet 32 ​​without passing through the heat exchanger 60. When the second wind wheel 52 rotates, air can enter from the bottom first air inlet 21 and the front first air outlet 31. The two air streams converge in front of the heat exchanger 60 and then pass through the heat exchanger 60 to achieve the effect of rapidly increasing the temperature. After the cold air passes through the second wind wheel 52, it is discharged along the air duct of the second air outlet 32;

[0062] Cooling: The first impeller 51 rotates, while the second impeller 52 remains stationary. The movable baffle 23 moves leftward to prevent air from entering the first air inlet 1 and being discharged directly from the first air outlet 31 without passing through the heat exchanger 60. When the first impeller 51 rotates, air enters from the second air inlet 22 and the second air outlet 32 ​​at the bottom. These two air streams merge before the heat exchanger 60 and pass through the condenser, achieving rapid cooling. After the hot air passes through the impeller and performs work, it is discharged through the first air outlet 31.

[0063] In summary, the air-conditioning system of the seat provided by the present invention can meet different heating and cooling needs in different usage scenarios, and has strong convenience and energy saving.

[0064] Furthermore, in some embodiments of the present invention, the air delivered by the first air outlet 31 may be too strong, causing discomfort to some people. The first air outlet 31 is provided with an auxiliary air outlet adjustment structure. The structure of the auxiliary adjustment structure includes, but is not limited to, an air guide plate; or a porous plate; or the air is divided into multiple streams, each of which is provided with multiple switch regulators, allowing the user to switch one or more combinations of these in different states. Other forms of the auxiliary adjustment structure or other structural shapes that achieve equivalent functions should be easily conceivable to those skilled in the art, and therefore will not be elaborated on here.

[0065] In addition, in some embodiments of the present invention, the second air outlet 32 ​​can also be provided on the top of the seat back 12, and / or on other sides, so as to effectively reduce the air outlet speed and thus reduce the blowing feeling.
