Description

[Technical Field]

[0001] The present disclosure relates to an air conditioner and an airflow direction regulating member. [Background technology]

[0002] Conventionally, air conditioners have been proposed for providing effective air conditioning. For example, the air conditioner disclosed in Patent Document 1, during heating operation, if the difference between the room temperature measured by a room temperature sensor and the room temperature set by the remote control exceeds a predetermined value and this state is maintained for a predetermined period of time, will use the louvers to blow air upward from a generally downward direction at a compressor speed lower than a first rotation speed. This agitates the air in the room, allowing warm air near the ceiling to be provided to the user's living area near the floor. [Prior art documents] [Patent documents]

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the drawings, the same or equivalent elements are designated by the same reference numerals, and redundant description will be omitted.

[0010] An air conditioner 100 according to this embodiment will be described. Fig. 1 is a perspective view of the air conditioner 100. In the following description, the upper side, lower side, lower left side, upper right side, upper left side, and lower right side in Fig. 1 will be referred to as the upper side, lower side, left side, right side, front side, and rear side of the air conditioner 100. The air conditioner 100 of this embodiment is an indoor unit of an air conditioning system that performs refrigeration cycle operation.

[0011] As shown in FIG. 1, the air conditioner 100 includes a housing 101, a blower unit 102, an air direction adjusting plate 103, a front panel 104, a control unit, and the like. The housing 101 has an air inlet and an air outlet 110. In this example, the housing 101 is box-shaped and long in the left-right direction. The air inlet is provided on the top surface of the housing 101. The air outlet 110 is provided at the bottom front of the housing 101. The air outlet 110 has a rectangular shape that is long in the left-right direction when viewed from the front, and opens toward the front.

[0012] An air flow passage is formed inside the housing 101, extending from the air inlet to the air outlet 110. The air blower 102 circulates the air drawn in from the air inlet toward the air outlet 110, which opens on the front side of the housing 101. In this example, the air blower 102 includes a heat exchanger disposed in the air flow passage, and an indoor fan surrounded by the heat exchanger.

[0013] The control unit is an electronic component that is provided inside the housing 101 and controls the operation of the air conditioner 100. In this example, the control unit is a processor such as a CPU, but it may also be an MCU (Micro Control Unit) or MPU (Micro Processor Unit), or it may also be an FPGA (Field Programmable Gate Array), ASIC (Application Specific Integrated Circuit), or other circuit with a calculation function.

[0014] The control unit controls at least the blower unit 102 and the airflow direction adjusting plate 103. For example, when the control unit receives a predetermined instruction from a remote control or the like, it starts operating the air conditioner 100. The blower unit 102 drives the indoor fan to draw outside air into the housing 101 through the air inlet. The blower unit 102 exchanges heat with the drawn air in the heat exchanger, and then sends the air out to the front through the air outlet 110.

[0015] The airflow direction adjusting plate 103 adjusts the direction of the air blown out from the air outlet 110. In this example, the airflow direction adjusting plate 103 is a plate-shaped member that is long in the left-right direction and is provided at the air outlet 110. The rear end of the airflow direction adjusting plate 103 is connected to the lower edge of the air outlet 110. The airflow direction adjusting plate 103 can swing up and down around an axis that extends left and right along the rear end.

[0016] The airflow direction adjustment plate 103 is displaceable between a closed position where it closes the air outlet 110 and an open position where it opens the air outlet 110. By changing the orientation of the airflow direction adjustment plate 103 in the open position, it is possible to adjust the direction of the air blown out from the air outlet 110. For example, when the airflow direction adjustment plate 103 is in an orientation where it extends horizontally, the airflow direction adjustment plate 103 blows air horizontally forward. The more the airflow direction adjustment plate 103 is tilted downward, the more the airflow direction adjustment plate 103 blows out air downward.

[0017] The air conditioner 100 of this embodiment is capable of performing various operations including heating operation, cooling operation, and dehumidifying operation. Alternatively, the air conditioner 100 may be capable of performing only heating operation or only cooling operation.

[0018] Front panel 104 is provided above air outlet 110 and can be opened and closed on the front side of housing 101. In this example, front panel 104 is a plate-like member that is long in the left-right direction and is provided on the front side of housing 101. An upper rear end of front panel 104 is connected to the front end of the top surface of housing 101. Front panel 104 can swing up and down around an axis that extends left and right along its upper rear end.

[0019] A front opening 111 that opens to the front and is higher than the air outlet 110 is provided on the front surface of the housing 101. The front panel 104 is displaceable between a closed position that closes the front opening 111 and an open position that opens the front opening 111. When the front panel 104 is in the open position, a user can attach and detach a dust box 105 into the housing 101 from the front side through the front opening 111. The dust box 105 collects dirt and dust removed from a filter installed in the housing 101.

[0020] The housing 101 includes an edge-shaped panel receiving surface 112 that extends laterally along the lower edge of the front opening 111. The panel receiving surface 112 is recessed slightly rearward relative to the front surface of the housing 101. When the front panel 104 is displaced to the closed position, the panel receiving surface 112 receives the open end 104A of the front panel 104. As a result, the front panel 104 is supported from the rear side by the panel receiving surface 112, and the front panel 104 is approximately flush with the front surface of the housing 101.

[0021] The air conditioner 100 is provided above the air outlet 110 in the housing 101 and includes a fixed portion 120 to which the fixing portion 201 (see FIGS. 2A and 2B) of the airflow direction regulating member 200 can be attached and detached. In this example, the fixed portion 120 is provided on the panel receiving surface 112 and extends to both the left and right along the upper edge of the air outlet 110. The fixed portion 120 is a hook-and-loop fastener to which the fixing portion 201 can be attached and detached, but it may also be a detachable adhesive sheet, hook, or snap button to which the fixing portion 201 can be attached and detached.

[0022] In this example, fixed part 120 is a single member extending to both the left and right of the upper edge of air outlet 110. Therefore, the left-right length of fixed part 120 is greater than the left-right length of the upper edge of air outlet 110. The left side portion of fixed part 120 extends to the left, straddling a position aligned vertically with the left end of the upper edge of air outlet 110. The right side portion of fixed part 120 extends to the right, straddling a position aligned vertically with the right end of the upper edge of air outlet 110.

[0023] Alternatively, fixed portion 120 may be composed of a plurality of members lined up in the left-right direction. For example, fixed portion 120 may be a plurality of hook-and-loop fasteners lined up at intervals in the left-and-right direction. Of these hook-and-loop fasteners, the leftmost hook-and-loop fastener may be located to the left of the left end of the upper side of air outlet 110, and the rightmost hook-and-loop fastener may be located to the right of the right end of the upper side of air outlet 110.

[0024] The air conditioner 100 includes a wind direction regulating member 200 that is detachable from the housing 101. Fig. 2A is a front view of the wind direction regulating member 200. Fig. 2B is a side view of the wind direction regulating member 200. In the following description, the upper and lower sides in Figs. 2A and 2B will be referred to as the upper and lower sides of the wind direction regulating member 200. The left and right sides in Fig. 2A will be referred to as the left and right sides of the wind direction regulating member 200. The left and right sides in Fig. 2B will be referred to as the front and rear sides of the wind direction regulating member 200.

[0025] 2A and 2B, airflow direction regulating member 200 includes fixed portion 201, hanging portion 202, and weight portion 203. Fixed portion 201 is fixed to the upper side of air outlet 101 in housing 101. Hanging portion 202 hangs down from fixed portion 201 to the front side of air outlet 101 due to its own weight. Weight portion 203 is provided at the end opposite fixed portion 201, and applies a load to hanging portion 202.

[0026] The fixing part 201 is a member that extends in the left-right direction at the upper end of the wind direction regulating member 200, and is composed of a base and a detachable part. For example, the base of the fixing part 201 is a relatively thick plate-shaped member made of resin, and has enough rigidity not to bend under the load of the wind direction regulating member 200. Alternatively, the base of the fixing part 201 may be a relatively thin strip-shaped member made of resin or cloth, and bend under the load of the wind direction regulating member 200.

[0027] A detachable portion of the fixing part 201 is provided on the back surface of the base part described above. In this example, the detachable portion of the fixing part 201 is a hook-and-loop fastener that is detachable from the fixing part 120. The detachable portion of the fixing part 201 may be an adhesive sheet, a hook, or a snap button, depending on the structure of the fixing part 120. In the fixing part 201, one detachable portion is provided over the entire back surface of the base part, but multiple detachable portions may also be provided side by side at intervals in the left-right direction on the back surface of the base part.

[0028] Fixing portion 201 is fixed to the rear surface of hanging portion 202, and extends in the left-right direction at the upper end of this rear surface. Both left and right ends of fixing portion 201 protrude to the left and right sides of hanging portion 202 when viewed from the front. The left-right length of fixing portion 201 is greater than the left-right length of the upper edge of air outlet 110. The vertical width of fixing portion 201 is approximately the same as the vertical width of fixed portion 120, but may be smaller than the vertical width of fixed portion 120.

[0029] Hanging portion 202 is a flexible sheet that can bend in a direction away from air outlet 110 upon receiving air blown out from air outlet 110. In this example, hanging portion 202 is a piece of cloth, but it may also be a thin, flexible resin sheet. In a front view, hanging portion 202 has a rectangular shape that is larger than air outlet 110 in order to cover air outlet 110, which has a rectangular shape that is long in the left-right direction. The left-right length and up-down length of hanging portion 202 are larger than the left-right length and up-down length of air outlet 110.

[0030] In this example, hanging portion 202 has a horizontally elongated rectangular shape when viewed from the front, and therefore the left-right length is greater than the up-down length. Alternatively, hanging portion 202 may have a vertically elongated rectangular shape when viewed from the front, in which the up-down length is greater than the left-right length, or a square shape in which the up-down length and the left-right length are equal. Hanging portion 202 is not limited to a rectangular shape when viewed from the front, and various shapes can be applied in consideration of design, such as a semicircular shape when viewed from the front, or a polygonal shape other than a square.

[0031] Weight portion 203 is a heavy object extending in the left-right direction at the lower end of wind direction regulating member 200. In this example, weight portion 203 is a metal cylinder extending in the left-right direction, and is attached to the lower end of hanging portion 202. Weight portion 203 is made up of a single heavy object extending across both the left and right ends of hanging portion 202, but may also be made up of multiple heavy objects lined up at intervals in the left-right direction. For example, if hanging portion 202 is sufficiently heavy, wind direction regulating member 200 does not need to include weight portion 203.

[0032] We will now explain how to attach and detach the air direction regulating member 200. Fig. 3 is a side view of the air conditioner 100 with the front panel 104 open. Fig. 4 is a front view of the air conditioner 100 shown in Fig. 3. Fig. 5 is a side view of the air conditioner 100 with the front panel 104 closed.

[0033] A user can attach the airflow direction regulating member 200 to the air conditioner 100 by following the procedure below. As shown in Fig. 3, the user opens the front panel 104 to the front and moves the front panel 104 from the closed position to the open position. This exposes the front opening 111 to the front, and also exposes the fixed portion 120 on the panel receiving surface 112 to the front.

[0034] Next, the user fixes the fixing part 201 of the airflow direction regulating member 200 to the fixed part 120 from the front side so that the up-down, left-right directions of the airflow direction regulating member 200 approximately coincide with the up-down, left-right directions of the air conditioner 100. In this example, since both the fixing part 201 and the fixed part 120 are hook-and-loop fasteners, the fixing part 201 is fixed to the fixed part 120 simply by pressing the fixing part 201 against the fixed part 120.

[0035] In this example, the left-right length of the fixed part 120 is only slightly longer than the left-right length of the fixing part 201. Therefore, the user can attach the wind direction regulating member 200 in a predetermined appropriate position simply by aligning and attaching the fixing part 201 so that both left and right ends of the fixing part 201 approximately coincide with both left and right ends of the fixing part 120. Alternatively, if the fixing part 120 is longer in the left-right direction than the fixing part 201, a mark indicating the appropriate attachment position of the fixing part 201 may be provided on or near the fixing part 120.

[0036] Thereafter, when the user releases wind direction regulating member 200, hanging portion 202 hangs down by its own weight from fixing portion 201 fixed to fixed portion 120. As shown in Fig. 5, the user closes front panel 104 rearward, causing front panel 104 to move from the open position to the closed position. At this time, front panel 104 closes front opening 111, and open end 104A of front panel 104 comes into contact with fixing portion 201 from the front side. Fixing portion 201 is sandwiched between open end 104A of front panel 104 and panel receiving surface 112 of housing 101.

[0037] In this way, when front panel 104 is closed, fixing part 201 fixed to the upper side of air outlet 110 is sandwiched between front panel 104 and housing 101. This maintains the connection between fixing part 201 and fixed part 120, so that wind direction regulating member 200 is stably fixed to air conditioner 100 and natural falling of wind direction regulating member 200 is suppressed.

[0038] An air conditioner 100 equipped with air direction regulating member 200 will be described. When viewed from the front side of housing 101, hanging portion 202 includes a portion that overlaps with air outlet 110 and covers at least the entire upper end region of air outlet 110 in the left-right direction. In this example, when hanging portion 202 hangs down from fixing portion 201, the lower end of hanging portion 202 is located below the lower end of air outlet 110.

[0039] 4 and 5, hanging portion 202 hangs down in front of air outlet 110 and faces the entire air outlet 110 in the front-to-rear direction, and therefore covers the entire air outlet 110 in a front view. Since hanging portion 202 extends further to the left and right and above and below than air outlet 110 in a front view, air from air outlet 110 is blown inward from the periphery of hanging portion 202. This ensures that substantially the entire air sent out from air outlet 110 is blown toward hanging portion 202.

[0040] Hanging portion 202 receives the air blown out from air outlet 110 and displaces to guide the air downward, thereby restricting the air from flowing upward. In this example, as shown in FIG. 5 , the air blown from air outlet 110 to hanging portion 202 urges hanging portion 202 forward. Flexible hanging portion 202 bends forward due to the urging force of the air. The upper end of hanging portion 202 is fixed to air conditioner 100 via fixing portion 201, whereas the lower end of hanging portion 202 is a free end that is not fixed. Therefore, hanging portion 202 bends in an arc shape in side view, so that the lower the hanging portion 202, the more it is displaced forward.

[0041] The air blown onto hanging portion 202 flows smoothly along the curved shape of hanging portion 202. At this time, the air is guided along hanging portion 202 so as to move downward and forward, and flows out downward from the lower end of hanging portion 202. As a result, even if the air blown out from air outlet 110 is a heating airflow that tends to rise, for example, hanging portion 202 can guide this heating airflow downward and prevent it from rising.

[0042] Alternatively, hanging portion 202 may cover at least the entire upper end region of air outlet 110, for example, the upper half of air outlet 110 in the left-right direction, when viewed from the front. In this case, the lower end of hanging portion 202 is located higher than the lower end of air outlet 110. The upper half of the air sent out forward from air outlet 110 is blown toward hanging portion 202. Because the air from air outlet 110 is blown inward from both the left and right ends of hanging portion 202, the air is less likely to flow out from both the left and right ends of hanging portion 202.

[0043] As in the above, hanging portion 202 receives the air blown out from air outlet 110 and displaces so as to guide the air downward. The air blown into hanging portion 202 is guided downward along the curved shape of hanging portion 202. Meanwhile, the lower half of the air delivered from air outlet 110 is not blown into hanging portion 202, but passes below hanging portion 202. Hanging portion 202 limits the height of the air that passes below hanging portion 202 and flows out to the front. As a result, even if the air delivered from air outlet 110 is a heating airflow that tends to rise, for example, hanging portion 202 can suppress the rising of this heating airflow.

[0044] 3, airflow direction adjustment plate 103 includes a first end P1 through which air flows into airflow direction adjustment plate 103 from air outlet 110, and a second end P2 through which the air that has flowed in from first end P1 flows out in a direction away from airflow direction adjustment plate 103. In this example, the rear end of the upper surface of airflow direction adjustment plate 103 through which air flows in from air outlet 110 is first end P1, and the front end from which this air flows out to the front is second end P2.

[0045] In a state in which hanging portion 202 hangs down from fixed portion 201, length L1 in the vertical direction from the upper edge of air outlet 110 to the lower end of hanging portion 202 may be equal to or greater than distance L2 between first end P1 and second end P2 of airflow direction adjusting plate 103. In the example of FIG. 3 , length L1 is the length from the point where hanging portion 202 intersects with imaginary plane V to the lower end of hanging portion 202. Imaginary plane V is an imaginary horizontal plane that passes through the upper edge of air outlet 110.

[0046] Distance L2 between first end P1 and second end P2 is the total length of the surface portion of airflow direction adjusting plate 103 through which air blown out from air outlet 110 flows. In this example, distance L2 is equal to the length by which airflow direction adjusting plate 103 protrudes forward from air outlet 110. In other words, distance L2 is the distance over which air is guided along airflow direction adjusting plate 103. When length L1 is equal to or greater than distance L2, the lower end of hanging portion 202 is at a height position below second end P2 of airflow direction adjusting plate 103, even if the inclination of airflow direction adjusting plate 103 changes to adjust the wind direction, for example. Therefore, hanging portion 202 can reliably receive the air flowing out forward from second end P2 of airflow direction adjusting plate 103.

[0047] In this example, as shown in Fig. 3, length L1 is greater than distance L2. Even if airflow direction adjusting plate 103 is opened to extend vertically downward, the lower end of hanging portion 202 is at a height position equal to or lower than second end P2 of airflow direction adjusting plate 103. Therefore, even if the inclination of airflow direction adjusting plate 103 changes during airflow, hanging portion 202 can reliably receive the air blown out from airflow direction adjusting plate 103.

[0048] In a state in which fixing portion 201 is attached to fixee portion 120, the length in the left-right direction of fixing portion 201 may be greater than the length in the left-right direction of the end of hanging portion 202 that is closest to fixing portion 201. In this example, as shown in FIG. 4 , the upper end of hanging portion 202 is the part of hanging portion 202 that is closest to fixing portion 201. Fixing portion 201 extends further to both the left and right than the upper end of hanging portion 202. Therefore, fixing portion 201 attached to fixee portion 120 can support the entire upper end of hanging portion 202 in the left-right direction, and therefore, hanging portion 202 can be curved in a stable posture when, for example, blowing air.

[0049] In a state in which the fixing part 201 is attached to the fixed part 120, the length of the fixing part 120 in the left-right direction may be greater than the length of the fixing part 201 in the left-right direction. In this example, as shown in Fig. 4, the fixing part 120 extends slightly further to both the left and right than the fixing part 201. Therefore, the fixing part 120 to which the fixing part 201 is attached can support the fixing part 201 over the entire left-right direction, and therefore, it is possible to prevent the wind direction regulating member 200 from falling when, for example, air is being blown.

[0050] The air blowing operation of the air conditioner 100 equipped with the air direction regulating member 200 will be described. Figures 6A to 6E are schematic vertical cross-sectional views of the air conditioner 100 performing air blowing operation. For ease of explanation, Figures 6A to 6E only show a portion of the air conditioner 100.

[0051] As described above, the control unit of air conditioner 100 starts operating air conditioner 100 when it receives an instruction to start operation from, for example, a remote control. As shown in FIG. 6A , in airflow direction control member 200, hanging portion 202 receives air from air outlet 110 and bends forward, thereby restricting the air from flowing upward. The airflow from air outlet 110 flows downward along hanging portion 202, making it possible to efficiently adjust the temperature near the floor where people are present in the room. Even when the airflow sent out from air outlet 110 is a heating airflow that tends to rise, the heating effect can be improved by guiding this airflow downward with airflow direction control member 200.

[0052] In this example, when the control unit of the air conditioner 100 receives an instruction to stop blower unit 102, it executes a first operation in which it drives blower unit 102 so that air is blown out from air outlet 110, while displacing air direction adjustment plate 103 from the open position toward the closed position. Specifically, as shown in Fig. 6B, when the control unit receives an instruction to stop operation from the remote control, it continues to drive blower unit 102, while displacing air direction adjustment plate 103, which is in the open position, upward so that the opening width of air outlet 110 becomes narrower.

[0053] At this time, as airflow direction adjusting plate 103 is displaced upward, the air blowing direction changes upward, and the opening width of air outlet 110 narrows, increasing the air velocity. As a result, a relatively strong airflow is blown toward the upper portion of hanging portion 202, causing hanging portion 202 to bend more forward than during normal operation (see FIG. 6A ), and move farther forward away from airflow direction adjusting plate 103. Therefore, when airflow direction adjusting plate 103 is closed during shutdown, hanging portion 202 can be prevented from entering air outlet 110, and airflow direction adjusting plate 103 can be prevented from getting caught on hanging portion 202.

[0054] Furthermore, in this example, when airflow direction adjustment plate 103, which is in the open position during first operation, assumes a predetermined position, the control unit of air conditioner 100 executes a second operation in which airflow direction adjustment plate 103 is displaced to the closed position while stopping blower unit 102 so that air does not blow out from air outlet 110. Specifically, as shown in Fig. 6C, the control unit displaces airflow direction adjustment plate 103 upward while continuing to drive blower unit 102 until airflow direction adjustment plate 103 assumes a position in which it extends horizontally.

[0055] 6D , when airflow direction adjustment plate 103 assumes a horizontally extending position, control unit 102 stops driving blower unit 102. This stops air from being blown out from air outlet 110, and hanging portion 202 hangs down from fixed portion 201 due to its own weight. At this time, hanging portion 202 is displaced rearward to a position where it contacts the front end of airflow direction adjustment plate 103. The front end of airflow direction adjustment plate 103 supports hanging portion 202 from the rear side, so that hanging portion 202 hangs down without entering air outlet 110.

[0056] 6E, the control unit stops driving blower unit 102 and displaces airflow direction adjustment plate 103 upward to the closed position where airflow direction adjustment plate 103 blocks air outlet 110. At this time, the front end of airflow direction adjustment plate 103 moves upward along the back surface of hanging portion 202, thereby preventing hanging portion 202 from climbing over the front end of airflow direction adjustment plate 103 and entering air outlet 110. Therefore, airflow direction adjustment plate 103 can be displaced to the closed position to block air outlet 110 while being prevented from getting caught in hanging portion 202.

[0057] The second operation is not limited to the above-described embodiment. For example, in the second operation, the control unit may continue driving blower unit 102 while displacing airflow direction adjustment plate 103 to the closed position, and then stop driving blower unit 102. The predetermined posture in the second operation is not limited to a posture in which airflow direction adjustment plate 103 extends horizontally, but may be a posture in which the front end of airflow direction adjustment plate 103 can come into contact with the back surface of hanging portion 202 when hanging portion 202 returns to the hanging state.

[0058] The present disclosure is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. Furthermore, new technical features can be formed by combining the technical means disclosed in each embodiment. [Explanation of symbols]
