Description

空调器air conditioner

本发明涉及在室内机本体内部具有由前侧热交换器与后侧热交换器所组成的倒V形室内热交换器的空调器。The invention relates to an air conditioner with an inverted V-shaped indoor heat exchanger composed of a front heat exchanger and a rear heat exchanger inside an indoor unit body.

以往的空调器系在前面与上在面机分别具有吸入口的本体内部、容纳由前侧热交换器与后侧热交换器形成倒V形室内热交换器的空调器。在这种空调器中，分别在前侧热交换器与后侧热交换器的下部设置为聚集从各热交换器产生的泄水的泄水盘，此外，为缩小室内机本体的上下尺寸，将送风机配置在前侧热交换器与后侧热交换器间、以使之被这些热交换器所覆盖。A conventional air conditioner is an air conditioner in which an inverted V-shaped indoor heat exchanger is formed by a front side heat exchanger and a rear side heat exchanger inside a main body having suction ports on the front and top sides, respectively. In this type of air conditioner, drain pans are provided at the lower parts of the front heat exchanger and the rear heat exchanger respectively to collect the drain water generated from each heat exchanger. In addition, in order to reduce the vertical size of the indoor unit body, The blower is disposed between the front heat exchanger and the rear heat exchanger so as to be covered by these heat exchangers.

然而，由于要使结构紧凑，而将送风机靠近后侧热交换器配置，使通过后侧热交换器的经热交换的空气流速变大。因此，使在后侧热交换器产生的泄水流向送风机侧，在制冷时等泄水发生较多的场合，该泄水并不流向设置在后侧热交换器下部的泄水盘，而从流经后侧热交换的中途就向送风机侧滴下，飞散到空调室中。However, in order to make the structure compact, the air blower is arranged close to the rear heat exchanger, so that the flow rate of the heat-exchanged air passing through the rear heat exchanger becomes large. Therefore, the drain water generated in the rear heat exchanger is made to flow to the blower side. When a large amount of drain water occurs during cooling, etc., the drain water does not flow to the drain pan installed at the lower part of the rear heat exchanger. In the middle of passing through the heat exchange on the rear side, it drips toward the air blower side and is scattered into the air-conditioning room.

因此，本发明目的在于提供能确实防止泄水从流经后侧热交换器的中途向送风机侧滴下的空调器。Therefore, an object of the present invention is to provide an air conditioner capable of reliably preventing drain water from dripping toward the blower side from the middle of flowing through the rear heat exchanger.

为了达到上述目的的本发明，对于在其本体前面与上面分别形成吸入口、在本体内容纳用分别面对上述各吸入口的前侧热交换器与后侧热交换器形成倒V形的室内热交换器、同时设置由这些前侧热交换器与后侧热交换器覆盖的送风机，且分别在上述前侧热交换器与后侧热交换器的下部设置泄水盘的空调器，其特征在于在上述后侧热交换器与送风机间、设置位于后侧热交换器的下风侧遮挡板。In order to achieve the above-mentioned purpose of the present invention, a suction port is formed on the front and top of the body, and the front side heat exchanger and the rear side heat exchanger respectively facing the above-mentioned suction ports are accommodated in the body to form an inverted V-shaped chamber. A heat exchanger, an air conditioner in which a blower covered by these front heat exchangers and rear heat exchangers is installed at the same time, and a drain pan is respectively installed under the front heat exchangers and rear heat exchangers, is characterized in that The leeward shielding plate located at the rear heat exchanger is provided between the rear heat exchanger and the air blower.

采用上述结构，使从本体上面的吸入口经后侧热交换器流向送风机的经热交换空气的一部分受遮挡板阻挡。具体说，由于将遮挡板设置在后侧热交换器的下风侧，即配置在后侧热交换器的接近送风机的风速最高的部分。因此，使原先风速不得不变高的此部分的风速因遮挡板而减小，在后侧热交换器产生的泄水，不会再象原先那样流向送风机侧，而正常地向下流到泄水盘侧。With the above structure, part of the heat-exchanged air flowing from the suction port on the main body to the blower through the rear heat exchanger is blocked by the baffle plate. Specifically, since the baffle plate is arranged on the leeward side of the rear heat exchanger, that is, it is arranged at the part of the rear heat exchanger near the air blower where the wind speed is the highest. Therefore, the wind speed at this part where the original wind speed had to be increased is reduced by the baffle plate, and the drain water generated by the heat exchanger on the rear side will no longer flow to the blower side as before, but will normally flow downward to the drain water. plate side.

此外，也可以将上述遮挡板的下部呈重叠状设置在后侧热交换器的泄水盘的内侧。据此，后侧热交换器的泄水即使一时向下滴向送风机侧，滴下的泄水受上述遮挡板阻挡，经遮挡板而被导向后侧热交换器的泄水盘。In addition, the lower part of the above-mentioned baffle plate may be arranged in an overlapping manner inside the drain pan of the rear side heat exchanger. Accordingly, even if the drain water from the rear heat exchanger temporarily drips downward toward the blower side, the dripped drain water is blocked by the baffle plate and guided to the drain pan of the rear heat exchanger through the baffle plate.

此外，也可以在上述遮挡板的下部与泄水盘内侧间形成间隙。据此，由于经过后侧热交换器下端的热交换空气通过上述间隙流向送风机侧，空气流动未被遮挡板完全阻止，因而能避免送风特性下降。此外，考虑到因后侧热交换器对遮挡板的冷却而在遮挡板的送风机侧的面上会产生泄水，但由于遮挡板下部与泄水盘内侧间形成有间隙，该泄水被引向泄水盘而进行回收。In addition, a gap may be formed between the lower portion of the shielding plate and the inner side of the drain pan. Accordingly, since the heat-exchanged air passing through the lower end of the rear heat exchanger flows toward the blower side through the gap, the flow of air is not completely blocked by the baffle plate, thereby avoiding deterioration of blowing characteristics. In addition, considering that the cooling of the baffle by the rear heat exchanger may cause water leakage on the surface of the baffle on the blower side, the drain is diverted due to the gap formed between the lower part of the baffle and the inner side of the drain pan. Recycle to the drain pan.

此外，也可以将上述遮挡板设置成把从后侧热交换器大致中间的下侧遮挡住。用遮挡板将后侧热交换器全部遮挡住就没有意义了、另外，作为泄水下滴的场所，使自上而下的泄水从一定程度变多的中间部滴下。因此，以仅将下侧遮蔽为好。In addition, the shielding plate may be provided so as to shield the lower side from the substantially middle of the rear side heat exchanger. It is useless to cover all the rear side heat exchangers with a shielding plate. In addition, as a place where the drain water drips, the drain water from top to bottom drips from the middle part which increases to a certain extent. Therefore, it is better to shield only the lower side.

此外，也可以使上述遮挡板兼作送风机的卷绕开始部，这样，因遮挡板，使送风机的卷绕开始部向吸入侧移动，使排出侧区域扩大。这样，通过使排出侧区域扩大，使吸入侧与排出侧的风压更趋于平衡，使原先容易发生的喘振现象(吸入侧与排出侧的逆转现象)消失，在提高送风特性的同时，也使送风声音减小。In addition, the shutter plate may also be used as the wind-up start portion of the blower, so that the wind-up portion of the blower moves toward the suction side due to the shutter plate, thereby expanding the area on the discharge side. In this way, by enlarging the area on the discharge side, the wind pressure on the suction side and the discharge side are more balanced, and the surge phenomenon (reversal phenomenon between the suction side and the discharge side) that is easy to occur before disappears, while improving the air supply characteristics. , but also to reduce the sound of the air supply.

此外，也可以在与上述遮挡板不面对面的后侧热交换器部分的热交换风机上形成(切割形成)缝隙。这样，可以使在后侧热交换器的不面对遮挡板的部分产生的泄水被上述缝隙阻拦、沿缝隙被引向下侧有遮挡板的部分。因此，能防止泄水从后侧交换器的不面对遮挡板的部分向下滴向送风机侧。In addition, a slit may be formed (cut and formed) in the heat exchange fan of the rear side heat exchanger portion that does not face the shielding plate. In this way, the drain water generated in the part of the rear heat exchanger not facing the baffle plate can be blocked by the above-mentioned slit, and be guided to the part with the baffle plate on the lower side along the slit. Therefore, it is possible to prevent drain water from dripping downward toward the blower side from the portion of the rear side exchanger that does not face the shielding plate.

此外，可以将上述遮挡板的大致中间部沿其纵向形成凸状。这样，能提高遮挡板的强度，同时能提高热交换器与遮挡板间的安装强度。Moreover, the substantially middle part of the said shielding board may be formed in convex shape along the longitudinal direction. In this way, the strength of the shielding plate can be improved, and at the same time, the installation strength between the heat exchanger and the shielding plate can be improved.

此外，可以在所述遮挡板的纵向两端部形成固定片，使该固定片被后侧热交换器端板与送风机轴承座夹持。由此，能将遮挡板可靠地固定。In addition, a fixing piece may be formed at both longitudinal ends of the shielding plate, and the fixing piece is clamped by the end plate of the rear heat exchanger and the bearing housing of the blower. Thereby, the shielding plate can be fixed reliably.

以下，参照附图对本发明一实施例进行说明。Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

图1为表示空调器室内机本体1的侧剖视图。如图所示，此室内机本体1由形成后背部的后板本体2、形成上面部的前面板3以及形成正面部的格栅4组成。在上述前面板3上形成上侧吸入口5、在吸入格栅4上形成前侧吸入口6。FIG. 1 is a side sectional view showing an air conditioner indoor unit body 1 . As shown in the figure, the indoor unit body 1 is composed of a rear panel body 2 forming the back portion, a front panel 3 forming the upper portion, and a grille 4 forming the front portion. An upper suction port 5 is formed on the front panel 3 , and a front suction port 6 is formed on the suction grill 4 .

在这样的室内机本体1的内部容纳形成为倒V形的室内热交换器7。此热交换器7具有面对前侧吸入口4的前侧热交换器8和面对上侧吸入口5的后侧热交换器9，将前侧热交换器8与后侧热交换器9的上部按规定角度连接成倒V形状。此外，在后侧热交换器9的上方设置辅助热交换器10、各热交换器8、9、10分别由隔开规定间隔配置的热交换风机11和穿过这些风机11的制冷剂配管12所构成。Inside such an indoor unit body 1 is housed an indoor heat exchanger 7 formed in an inverted V shape. This heat exchanger 7 has a front heat exchanger 8 facing the front suction port 4 and a rear heat exchanger 9 facing the upper suction port 5, and the front heat exchanger 8 and the rear heat exchanger 9 are connected to each other. The upper part is connected into an inverted V shape according to a specified angle. In addition, an auxiliary heat exchanger 10 is provided above the rear heat exchanger 9, and each heat exchanger 8, 9, 10 is composed of heat exchange fans 11 arranged at predetermined intervals and refrigerant piping 12 passing through these fans 11. constituted.

在前侧热交换器8的下部与后侧热交换9的下部分别配置泄水盘13、14，在前侧热交换器8与后侧热交换器9之间配置用此两热交换器8、9覆盖的送风机15。采用这一结构，通过驱动送风机15，室内空气经过前侧吸入口6与上侧吸入口5被吸入，再通过前侧热交换器8和后侧热交换器9以及通风道16从排出口17被吹向室内。其时，使在各热交换器8、9发生的泄水分别集聚在泄水盘13、14内。此外，在排出口17设置上下气窗18和左右气窗。The bottom of the front heat exchanger 8 and the bottom of the rear heat exchanger 9 are respectively equipped with drain pans 13 and 14, and these two heat exchangers 8 are arranged between the front heat exchanger 8 and the rear heat exchanger 9. , 9 covered blower 15 . With this structure, by driving the air blower 15, the indoor air is sucked through the front side suction port 6 and the upper side suction port 5, and then passes through the front side heat exchanger 8 and the rear side heat exchanger 9 and the air passage 16 from the discharge port 17. blown indoors. At this time, the drain water generated in each heat exchanger 8, 9 is accumulated in the drain pans 13, 14, respectively. In addition, upper and lower louvers 18 and left and right louvers are provided in the discharge port 17 .

本实施例的特点是在后侧热交换器9与送风机15间、设置位于后侧热交换器9的下风侧(后侧热交换器9接近送风机15的部分)遮挡板20。如图4所示，遮挡板20具有与后侧热交换器9的水平方向的长度大致相等的长度，配置成从后侧热交换器9的大致中间将下侧遮挡。将遮挡板20的大致中间部21形成沿其纵长方向凸出的凸状、是为达到提高遮挡板20的自身强度与安装强度。The characteristic of this embodiment is that a shielding plate 20 located on the leeward side of the rear heat exchanger 9 (the part of the rear heat exchanger 9 close to the blower 15 ) is provided between the rear heat exchanger 9 and the blower 15 . As shown in FIG. 4 , the shielding plate 20 has a length substantially equal to the length of the rear heat exchanger 9 in the horizontal direction, and is arranged to shield the lower side of the rear heat exchanger 9 from substantially the middle. The purpose of forming the substantially middle portion 21 of the shielding plate 20 in a convex shape protruding along its longitudinal direction is to improve the self-strength and installation strength of the shielding plate 20 .

如图2、图3所示，利用在其一侧面上设置的安装片22将遮挡板20安装在后侧热交换器9上。如图4所示，将安装片22沿遮挡板20的纵向按隔开规定间隔设置，其上具有与后侧热交换器9的制冷剂配管11接合的接合爪23。接合爪23具有可将制冷剂配管11嵌入的圆弧部24，形成两个一组、将制冷剂配管11夹入其内侧或外侧。As shown in FIGS. 2 and 3 , the shielding plate 20 is mounted on the rear side heat exchanger 9 by using the mounting piece 22 provided on one side thereof. As shown in FIG. 4 , the mounting pieces 22 are provided at predetermined intervals in the longitudinal direction of the shielding plate 20 , and have engagement claws 23 engaged with the refrigerant pipes 11 of the rear heat exchanger 9 . The engagement claws 23 have arcuate portions 24 into which the refrigerant pipes 11 can be fitted, are formed in pairs, and sandwich the refrigerant pipes 11 inside or outside.

如图4所示，在遮挡板20的纵向两端部上形成固定片25，以使这些固定片25被后侧热交换器9的端板(未图示)和其上载放着此端板的送风机15的轴承基座(未图示)夹持。通过用此固定片25固定与用所述安装片22的安装，把安装片22因振动等从制冷剂配管11脱落也考虑在内，能将遮挡板20可靠固定。As shown in FIG. 4, fixing pieces 25 are formed on both longitudinal ends of the shielding plate 20, so that these fixing pieces 25 are supported by the end plate (not shown) of the rear side heat exchanger 9 and the end plate on which the end plate is placed. The bearing base (not shown) of the air blower 15 is clamped. By fixing with this fixing piece 25 and attaching with the above-mentioned mounting piece 22, the shielding plate 20 can be securely fixed taking into consideration that the mounting piece 22 falls out of the refrigerant pipe 11 due to vibration or the like.

如图2、图3所示，在遮挡板20的下部具有与后侧热交换器9平行形成的平板部20a，在上部具有在后侧热交换器9的上方开放的倾斜部20b。将斜部20b配置成从后侧热交换器9的大致中间将下侧遮蔽，聚集从后侧热交换器9滴下的泄水。将平板部20a配置成与后侧热交换器9的泄水盘14的内侧重叠，用斜部20b把聚集的泄水导向泄水盘14。As shown in FIGS. 2 and 3 , the baffle plate 20 has a flat plate portion 20a formed parallel to the rear heat exchanger 9 at the lower portion, and an inclined portion 20b opened above the rear heat exchanger 9 at the upper portion. The inclined portion 20b is arranged so as to shield the lower side from substantially the middle of the rear heat exchanger 9, and the drain water dripped from the rear heat exchanger 9 is collected. The flat plate portion 20a is arranged to overlap the inner side of the drain pan 14 of the rear heat exchanger 9, and the accumulated drain water is guided to the drain pan 14 by the inclined portion 20b.

如图2所示，在平板部20a与泄水盘14的内侧间形成间隙26。此外，在后侧热交换器9与后板27间设置绝热材料28。沿后侧热交换器9的水平方向间隔设置绝热材料28，成为使后侧热交换器9的下端与后板27间不产生空气流动。用此结构使沿后板27一侧流动的空气可靠地流入后侧热交换器9，在那里进行热交换后通过遮挡板20的平板部20a与泄水盘14内侧间的间隙26流向送风机15一侧。As shown in FIG. 2 , a gap 26 is formed between the flat plate portion 20 a and the inner side of the drain pan 14 . In addition, a heat insulating material 28 is provided between the rear heat exchanger 9 and the rear plate 27 . The heat insulating material 28 is provided at intervals along the horizontal direction of the rear heat exchanger 9 so that air does not flow between the lower end of the rear heat exchanger 9 and the rear plate 27 . With this structure, the air flowing along the side of the rear plate 27 reliably flows into the rear side heat exchanger 9, where after heat exchange, it flows to the air blower 15 through the gap 26 between the flat plate portion 20a of the baffle plate 20 and the inner side of the drain pan 14. side.

此外，如图5所示，遮挡板20兼作送风机15的开始卷绕部。就是用在遮挡板20的大致中间部21形成凸状，使最接近送风机15的部分，就是使送风机15的排出侧29的区域向吸入侧仅扩大θ角度。此外，如图2所示，在后侧热交换器9的不面对遮挡板20的部分9a的热交换风机12上形成缝隙31。通过将热交换风机12的一部沿其纵向切割形成缝隙31。此外，在图2中，在后侧热交换器9的面对遮挡板20的部分9b上也设置缝隙引，然而，也不以不设。In addition, as shown in FIG. 5 , the shielding plate 20 also serves as a winding start portion of the air blower 15 . That is, the substantially middle part 21 of the baffle plate 20 is formed into a convex shape, so that the part closest to the air blower 15, that is, the area on the discharge side 29 of the air blower 15 is enlarged by only the angle θ toward the suction side. Further, as shown in FIG. 2 , a slit 31 is formed in the heat exchange fan 12 of the portion 9 a of the rear side heat exchanger 9 that does not face the shielding plate 20 . The slit 31 is formed by cutting a part of the heat exchange fan 12 in its longitudinal direction. In addition, in FIG. 2, a slit guide is also provided on the portion 9b of the rear side heat exchanger 9 facing the baffle plate 20, however, it is not optional.

现对由上述结构所构成的本实施形态的作用进行说明。Now, the operation of this embodiment constituted by the above-mentioned structure will be described.

使从本体1的上面吸入口5通过后侧热交换器9流向送风机15经热交换的空气的一部分因遮挡板20的阻挡而减速。具体说，由于将遮挡板20配置在后侧热交换器9的下风侧，即成为将其配置在接近送风机15的后侧热交换9的风速最高的部分。因此，使原来风速不得不变高的此部分的风速因遮挡板20而减速，在后侧热交换器9上产生的泄水不会象原来那样流向送风机15一侧，而正常地向下流向泄水盘14。A part of the heat-exchanged air flowing from the upper suction port 5 of the main body 1 to the blower 15 through the rear heat exchanger 9 is decelerated by the baffle plate 20 . Specifically, since the baffle plate 20 is arranged on the leeward side of the rear heat exchanger 9 , it is arranged near the air blower 15 at the part where the wind speed of the rear heat exchanger 9 is the highest. Therefore, the wind speed of this part where the original wind speed has to be increased is decelerated by the baffle plate 20, and the drain water generated on the rear side heat exchanger 9 will not flow to the blower 15 side as before, but will normally flow downward. Drain pan 14.

此外，由于使遮挡板20的下部平板部20a与后侧热交换器9的泄水盘14的内侧重叠，即使在后侧热交换器9产生的泄水暂时向送风机15一侧滴下，滴下的泄水被遮挡板20的斜部20b挡住而流经平板部20a被导向热交换器9和泄水盘14。In addition, since the lower flat plate portion 20a of the shielding plate 20 overlaps the inner side of the drain pan 14 of the rear heat exchanger 9, even if the drain water generated in the rear heat exchanger 9 temporarily drips toward the blower 15 side, the dripped The drain water is blocked by the inclined portion 20 b of the shielding plate 20 and flows through the flat plate portion 20 a to be guided to the heat exchanger 9 and the drain pan 14 .

此外，由于在遮挡板20下部的平板部20a与泄水盘14的内侧间形成间隙26，使从后侧热交换器9的后板27侧通过的空气通过遮挡板20的平板部20a与泄水盘14间的间隙26流向送风机15侧。这样，由于空气流动不因遮挡板20而完全受阻，就能避免送风特性下降。In addition, since the gap 26 is formed between the flat plate portion 20a at the bottom of the baffle plate 20 and the inner side of the drain pan 14, the air passing through the rear plate 27 side of the rear side heat exchanger 9 passes through the flat plate portion 20a of the baffle plate 20 and the drain pan 14. The gap 26 between the water pans 14 flows toward the air blower 15 side. In this way, since the flow of air is not completely obstructed by the baffle plate 20, it is possible to avoid deterioration of the air blowing characteristic.

此外，也考虑到遮挡板20因后侧热交换器9而被冷却、而在遮挡板20的送风机15一侧的面上产生泄水，然而，此泄水因在遮挡板20下部的平板部20a与泄水盘14的内侧向形成上述间隙26，而使经遮挡板20的表面导向泄水盘14再被回收。In addition, it is also considered that the shading plate 20 is cooled by the rear heat exchanger 9, and water leakage occurs on the surface of the shading plate 20 on the blower 15 side. 20a and the inner side of the drain pan 14 form the above-mentioned gap 26, so that the surface of the shielding plate 20 is guided to the drain pan 14 and then recovered.

此外，把遮挡板20配置成从后侧热交换器9的大致中间将下侧遮挡的理由在于：一方向，用遮挡板20将整个后侧热交换器9遮挡在通风上无意义，另一方面作为泄水的下滴场所，自上而下的泄水、是从增多到一定程度的中间部下滴的。因此，将遮挡板20设置在从后侧热交换器9的大致中间的下侧。In addition, the reason for disposing the shielding plate 20 so as to shield the lower side from approximately the middle of the rear side heat exchanger 9 is that, on the one hand, it is meaningless to shield the entire rear side heat exchanger 9 with the shielding plate 20 in terms of ventilation, and on the other hand On the one hand, as the dripping place of draining water, the draining water from top to bottom drips from the middle part that increases to a certain degree. Therefore, the shielding plate 20 is provided on the lower side from the substantially middle of the rear side heat exchanger 9 .

此外，通过设置遮挡板20、将送风机15的开始卷绕部向吸入侧30仅移动θ角，使排出侧29的区域扩大。这样，通过扩大排出侧29的区域，使吸入侧30与排出侧29的风压更趋于平衡，使原先容易发生的喘振现象(吸入侧30与排出侧29的倒转现象)消失，在提高送风特性的同时，也使排风声音减小。Furthermore, by providing the shielding plate 20 and moving the winding start portion of the air blower 15 toward the suction side 30 by an angle of θ, the area of the discharge side 29 is enlarged. In this way, by enlarging the area of the discharge side 29, the wind pressures on the suction side 30 and the discharge side 29 are more balanced, and the surge phenomenon (reversal phenomenon between the suction side 30 and the discharge side 29) that was easy to occur before disappears, and the wind pressure of the suction side 30 and the discharge side 29 is improved. While improving the air supply characteristics, it also reduces the exhaust sound.

此外，由于在与遮挡板20不面对面的后侧热交换器9部分9a的热交换风机12上形成缝隙(切割形成31，使在后侧热交换器9的与遮挡板20不面对面的部分9a上产生的泄水被缝隙31栏截、沿缝隙31导向下侧的遮挡板20的部分9b、在遮挡板20上滴下。因此，能防止泄水从与遮挡板20不面对面的热交换器9的部分9a向送风机15侧滴下。In addition, due to forming the slit (cutting and forming 31) on the heat exchange fan 12 of the rear side heat exchanger 9 part 9a not facing to the shielding plate 20, the part 9a of the rear side heat exchanger 9 not facing the shielding plate 20 is formed. The drain water generated above is intercepted by the slit 31, guided along the slit 31 to the lower part 9b of the baffle plate 20, and drips on the baffle plate 20. Therefore, it is possible to prevent the water from draining from the heat exchanger 9 that is not facing the baffle plate 20. The part 9a dripped toward the air blower 15 side.

综上所述，采用本发明的空调器，能可靠防止泄水从流经后侧热交换的中途向送风机15侧滴下。To sum up, adopting the air conditioner of the present invention can reliably prevent the drain water from dripping to the side of the air blower 15 from the middle of flowing through the heat exchange at the rear side.
