Description

顶棚式空调器的钟形口装置Bell Mouth Devices for Ceiling Air Conditioners

本发明涉及顶棚式空调器，尤其涉及顶棚式空调器的钟形口装置，该钟形口装置构造成可补偿因产品容量造成的产品高度的变化在风扇和钟形口之间产生的分开距离，并可共同使用多个钟形口中的一个。The present invention relates to ceiling-type air conditioners, and more particularly to a bellmouth arrangement for a ceiling-type air conditioner configured to compensate for a separation distance between a fan and the bellmouth due to variations in product height due to product volume , and may share one of several bellmouths.

作为现有技术，日本专利申请公开号为平成7-71400(公开于1995年3月14日)的文献中公开了一种配备了钟形口的轴流式鼓风机。如图1所示，该配备有钟形口的轴流式鼓风机被安置在外壳1内部，钟形口2的内部沿排气方向具有缓慢的曲面，而位于钟形口2的内侧按箭头所示的的吹气方向设置用于吹气的风扇3。钟形口2相对于外壳1安装成可轴向滑动以承受弹簧6a和6b朝排气方向所产生的力。As prior art, Japanese Patent Application Publication No. Heisei 7-71400 (published on March 14, 1995) discloses an axial blower equipped with a bell mouth. As shown in Figure 1, the axial flow blower equipped with a bell mouth is placed inside the housing 1, the inside of the bell mouth 2 has a slow curved surface along the exhaust direction, and the inner side of the bell mouth 2 is shown by the arrow. The blowing direction shown is provided with the fan 3 for blowing. The bellmouth 2 is axially slidably mounted relative to the housing 1 to withstand the force generated by the springs 6a and 6b in the direction of exhaust.

因为将钟形口2以低的静态压力定位于排气方向，因此这种钟形口2用来从风扇3的外侧吸气来加大吸气空间，从而可增加空气容量。Because the bell mouth 2 is positioned in the exhaust direction with low static pressure, this bell mouth 2 is used to suck air from the outside of the fan 3 to increase the suction space, thereby increasing the air capacity.

另外，当空气施加高静态压力并沿吸气方向通过点划线表示的钟形口2时，在风扇3的外部吸气一侧因空气的离心力不会发生流通，这时离心力增加了朝向排气一侧的静态压力。In addition, when the air exerts a high static pressure and passes through the bell-shaped mouth 2 indicated by the dotted line along the suction direction, no circulation occurs on the external suction side of the fan 3 due to the centrifugal force of the air, and the centrifugal force increases toward the discharge. Static pressure on the gas side.

因此，在大空气流量范围，钟形口2趋向于相对增加空气量，而在小空气流量范围，钟形口2增加了静态压力。图中未说明的标号4为支撑件，5为电机。Therefore, in the large air flow range, the bell mouth 2 tends to increase the air volume relatively, while in the small air flow range, the bell mouth 2 increases the static pressure. The number 4 not illustrated in the figure is a support member, and the number 5 is a motor.

此处描述的现有技术的这种具有钟形口的轴流式鼓风机中，钟形口2被弹簧6a和6b所支撑以在外壳1内部轴向滑动，在低静态压力下位于风扇3的外部排气方向，而在高静态压力下位于风扇3的外部吸气方向，以此可以补偿钟形口2和风扇3之间的隔离间距。然而，补偿结构不是通过添加独立的钟形口来实现，而是通过轴向滑动的钟形口2来实现。In this prior art axial blower with bell mouth described here, the bell mouth 2 is supported by springs 6a and 6b to slide axially inside the housing 1, at low static pressure at the bottom of the fan 3. In the direction of the external exhaust, and at high static pressure in the external suction direction of the fan 3, it is possible to compensate the separation distance between the bell mouth 2 and the fan 3. However, the compensating structure is realized not by adding a separate bellmouth, but by an axially sliding bellmouth 2 .

尤其是存在这样一个问题，因为这种用弹簧6a和6b支撑钟形口2使其轴向滑动的构造制作起来很复杂，钟形口2的不正确使用将会使钟形口2和风扇3之间的隔离间距没有被精确补偿。In particular, there is such a problem that because the construction of supporting the bell mouth 2 with the springs 6a and 6b so that it can slide axially is complicated to make, incorrect use of the bell mouth 2 will make the bell mouth 2 and the fan 3 The isolation spacing between them is not precisely compensated.

公开本发明用于解决上述问题，本发明的目的是提供一种顶硼式空调器的钟形口装置，用于补偿因产品容量(小容量或大容量)造成的产品高度的变化在风扇和钟形口之间产生的分开距离，并可共同使用多个钟形口中的一个，以便简化结构来精确补偿钟形口和风扇之间的分开距离。The present invention is disclosed to solve the above problems. The purpose of the present invention is to provide a bell mouth device of a top boron air conditioner, which is used to compensate the change of the product height caused by the product capacity (small capacity or large capacity) in the fan and The separation distance generated between the bell mouths, and one of the multiple bell mouths can be used in common, so as to simplify the structure and accurately compensate the separation distance between the bell mouths and the fan.

根据本发明的目的，提供了一种顶棚式空调器的钟形口装置，该空调器在其主体内部安置有将空气吸入主体以及排放该气体的风扇和与风扇保持预定间隙以引导空气吸入的钟形口装置，该钟形口装置包括：According to the object of the present invention, there is provided a bell mouth device of a ceiling type air conditioner, the air conditioner is provided inside its main body with a fan which sucks air into the main body and discharges the gas and a fan which maintains a predetermined gap with the fan to guide the air intake A bellmouth assembly comprising:

下面参照附图详细描述根据本发明的实施例。Embodiments according to the present invention will be described in detail below with reference to the accompanying drawings.

如图2所示，本发明提供的顶棚式空调器通过固定于顶棚壁的基本螺栓10将其主体20悬挂于顶棚上。As shown in FIG. 2 , the ceiling-type air conditioner provided by the present invention hangs its main body 20 on the ceiling through basic bolts 10 fixed to the ceiling wall.

主体20的内部中央配备有从下面吸气的鼓风装置30，鼓风装置30的外部配备有热交换器40，用于热交换所吸入的空气。热交换器40的下面配备有浓缩水垫60，用于收集并排出热交换器40产生的浓缩水以及将热交换器40与主体20的内壁保持预定距离，以便垂直形成多个通道50。浓缩水垫60的下面安装有钟形口装置70，使其与鼓风装置30保持预定距离以引导空气的吸入。The inside center of the main body 20 is provided with a blower device 30 which sucks air from below, and the outside of the blower device 30 is provided with a heat exchanger 40 for heat exchanging the sucked air. A concentrated water pad 60 is provided below the heat exchanger 40 for collecting and discharging concentrated water generated by the heat exchanger 40 and maintaining a predetermined distance between the heat exchanger 40 and the inner wall of the main body 20 to form a plurality of channels 50 vertically. A bell mouth device 70 is installed under the concentrated water pad 60 to keep a predetermined distance from the blower device 30 to guide the suction of air.

此处，鼓风装置30包括中心连接于主体20的电机31以及通过电机轴32同轴安装于电机31下面的由电机31激励旋转的螺旋桨式风扇33。另外，面板80固定在相对于主体20的下侧浓缩水垫60和钟形口装置70的下表面接合的位置，此处面板80被吸气口81和出气口82可分式地形成，覆盖主体20使其无法从外部看到，钟形口装置70和通道50各自以贴面方式相通，面板80上的吸气口81的下面连接到过滤部件90，用于过滤空气中漂浮的异物。Here, the blower device 30 includes a motor 31 centrally connected to the main body 20 and a propeller fan 33 coaxially installed under the motor 31 through a motor shaft 32 and driven to rotate by the motor 31 . In addition, the panel 80 is fixed at a position where the lower concentrated water pad 60 and the lower surface of the bell mouth device 70 are engaged with respect to the lower side of the main body 20, where the panel 80 is formed detachably by the suction port 81 and the gas outlet port 82, covering The main body 20 makes it impossible to see from the outside, the bell mouth device 70 and the channel 50 communicate with each other in a face-to-face manner, and the bottom of the suction port 81 on the panel 80 is connected to a filter member 90 for filtering foreign objects floating in the air.

如图3和图4所示，钟形口装置70具有第一钟形口100和添加于第一钟形口100上的第二钟形口110。第一钟形口100保持与风扇33的预定间隔，在小容量主体20的情况下，当主体20的高度降低时与主体20的高度相对应。第二钟形口110保持与风扇33的预定间隙，使风扇33和第一钟形口100之间的分开距离(L)可以在大容量主体20中主体20高度增加的情况下得到补偿。As shown in FIGS. 3 and 4 , the bellmouth device 70 has a first bellmouth 100 and a second bellmouth 110 added to the first bellmouth 100 . The first bell mouth 100 maintains a predetermined interval from the fan 33 corresponding to the height of the main body 20 when the height of the main body 20 is lowered in the case of the small capacity main body 20 . The second bellmouth 110 maintains a predetermined gap with the fan 33 so that the separation distance (L) between the fan 33 and the first bellmouth 100 can be compensated in the case of an increase in the height of the body 20 in the large-capacity body 20 .

换句话说，将第一钟形口100形成为其上部出口101的直径比其下部入口102的直径更窄，相对其中等外围高度分布于预定位置的多个螺丝套103整体垂直突出，通过包括例如多个螺母的联结部件120与第二钟形口110接合。In other words, the first bell mouth 100 is formed such that the diameter of its upper outlet 101 is narrower than that of its lower inlet 102, and a plurality of screw sleeves 103 distributed at predetermined positions relative to its middle peripheral height protrude vertically as a whole, by including A coupling member 120 such as a plurality of nuts is engaged with the second bellmouth 110 .

第二钟形口110上具有靠近风扇33的出口111和下面的与第一钟形口100的出口101面对相通的入口112。入口112的外围形成有水平延伸的凸缘113以适应螺丝套103。The second bell mouth 110 has an outlet 111 close to the fan 33 and an inlet 112 facing the outlet 101 of the first bell mouth 100 below. A flange 113 extending horizontally is formed on the periphery of the inlet 112 to accommodate the screw sleeve 103 .

凸缘113上连接螺丝套103的地方有多个连接孔114，使得在联结部件120的螺旋表面刺穿连接到螺丝套103时将第一钟形口100和第二钟形口110接合起来。很明显，也可以用粘接剂将第一钟形口100和第二钟形口110接合起来。未说明的标号130为包围主体20的内壁和顶棚的隔离材料。A plurality of connection holes 114 are formed on the flange 113 where the screw sleeve 103 is connected, so that the first bell mouth 100 and the second bell mouth 110 are joined when the helical surface of the coupling member 120 is pierced and connected to the screw sleeve 103 . Obviously, the first bell mouth 100 and the second bell mouth 110 can also be joined together by adhesive. An unexplained reference numeral 130 is an insulating material surrounding the inner wall and the ceiling of the main body 20 .

下面描述上述构成的本发明的使用效果。The effect of use of the present invention constituted as described above will be described below.

如图4所示，给鼓风装置30的电机31施加激励功率时，因电机31的激励而旋转的电机轴32以与其相同的速度同时旋转螺旋桨式风扇33。风扇33的旋转使室内空气按箭头所指顺序吸入主体20的内部中心，即，从在主体20下面形成的过滤部件90进入面板80的吸气口81和第一钟形口100，再被吸入到风扇33的内部中心部分。As shown in FIG. 4 , when excitation power is applied to the motor 31 of the blower device 30 , the motor shaft 32 rotated by the excitation of the motor 31 simultaneously rotates the propeller fan 33 at the same speed. The rotation of the fan 33 makes the indoor air suck into the inner center of the main body 20 in the order indicated by the arrow, that is, enter the suction port 81 and the first bell-shaped mouth 100 of the panel 80 from the filter member 90 formed below the main body 20, and then be sucked to the inner center portion of the fan 33.

此时，风扇33的下端与第一钟形口100上面的出口101保持预定间距，以便出口101的上面内部覆盖风扇33的下面外部，同时在二者之间保持确定间隙，使得通过第一钟形口100的空气由风扇33的下端吸入风扇33的内部中心部分，并且根据风扇33的叶片形状和风扇33的外围分布特性呈放射状传播，以便改变其流动。At this time, the lower end of the fan 33 maintains a predetermined distance from the outlet 101 above the first bell mouth 100, so that the upper interior of the outlet 101 covers the lower exterior of the fan 33, while maintaining a certain gap between the two, so that the first bell passes through. The air in the shaped port 100 is sucked into the inner central part of the fan 33 by the lower end of the fan 33, and spreads radially according to the blade shape of the fan 33 and the peripheral distribution characteristics of the fan 33, so as to change its flow.

经由风扇33的外围放射状传播的空气强制性通过包围风扇33的外围并与风扇33的外围保持预定间距的热交换器40，与热交换器40的表面接触被热交换为冷空气。The air radially propagating through the periphery of the fan 33 forcibly passes through the heat exchanger 40 surrounding the periphery of the fan 33 and maintaining a predetermined distance therefrom, and contacts the surface of the heat exchanger 40 to be heat-exchanged into cold air.

随后，因热交换器与空气之间的温度差在热交换器40的表面上产生的浓缩水沿热交换器40的表面流下并收集在位于热交换器40下面的浓缩水垫60处。然后通过排水管(未示出)排出浓缩水。Then, the condensed water generated on the surface of the heat exchanger 40 due to the temperature difference between the heat exchanger and the air flows down the surface of the heat exchanger 40 and is collected at the condensed water pad 60 located under the heat exchanger 40 . The concentrated water is then removed through a drain (not shown).

此外，热交换后的冷空气碰撞主体20的内壁和覆盖顶棚的隔离材料130，流到由隔离材料130和浓缩水垫60之间的预定间距形成于主体20下边缘的通道50，流到通道50的空气通过与通道50面对面相通的面板80的出气口82进入室内。In addition, the cold air after heat exchange collides with the inner wall of the main body 20 and the insulating material 130 covering the ceiling, flows to the channel 50 formed at the lower edge of the main body 20 at a predetermined distance between the insulating material 130 and the concentrated water pad 60, and flows to the channel. The air of 50 enters the room through the air outlet 82 of the panel 80 that communicates with the channel 50 face to face.

同时，保持预定高度并且下端入口102的尺寸大于上端出口101尺寸的第一钟形口100用于具有较短高度的小容量主体20，如图4所示。Meanwhile, the first bell mouth 100 , which maintains a predetermined height and whose lower end inlet 102 is larger in size than the upper end outlet 101 , is used for the small volume main body 20 having a shorter height, as shown in FIG. 4 .

然而，如图4所示，当主体20的高度增加，空调器的容量变大时，主体20、隔离材料130和热交换器40的高度通常会增大，从而在风扇33和第一钟形口100之间产生了预定分开距离(L)。However, as shown in FIG. 4, when the height of the main body 20 increases and the capacity of the air conditioner becomes larger, the heights of the main body 20, the insulating material 130, and the heat exchanger 40 generally increase, so that the fan 33 and the first bell shape A predetermined separation distance (L) is created between the ports 100 .

此时，当空调器的容量增大时，不需替换第一钟形口100，而是在其上添加第二钟形口110来补偿分开距离(L)。为联结第一钟形口100和第二钟形口110，第一钟形口100上端的出口101被第二钟形口110下端的入口112同轴接纳；同时，以第一钟形口100的外部中等外围高度整体垂直突出形成的多个螺丝套103适应于在第二钟形口110的凸缘113上形成的连接孔114，通过多个联结部件120来接合螺丝套103和凸缘113，将第一钟形口100和第二钟形口110装配在一起。At this time, when the capacity of the air conditioner is increased, instead of replacing the first bellmouth 100, the second bellmouth 110 is added thereon to compensate for the separation distance (L). For connecting the first bell mouth 100 and the second bell mouth 110, the outlet 101 at the upper end of the first bell mouth 100 is received coaxially by the inlet 112 at the lower end of the second bell mouth 110; A plurality of screw sleeves 103 formed vertically protruding from the outer middle peripheral height of the second bell mouth 110 are adapted to the connecting holes 114 formed on the flange 113 of the second bell mouth 110, and the screw sleeves 103 and the flange 113 are joined by a plurality of coupling parts 120 , assemble the first bellmouth 100 and the second bellmouth 110 together.

因此，不管产品容量如何，都可以共同使用第一钟形口100，并且在大容量空调器的情况下，可以将第一钟形口100连接于单独的第二钟形口110，从而可精确补偿风扇33和第一钟形口100之间的分开距离(L)。Therefore, the first bellmouth 100 can be commonly used regardless of the product capacity, and in the case of a large-capacity air conditioner, the first bellmouth 100 can be connected to a separate second bellmouth 110, so that precise The separation distance (L) between the fan 33 and the first bellmouth 100 is compensated.

从以上叙述可明显看出，本发明的顶棚式空调器的钟形口装置的优点在于：当小容量产品的容量降低使产品高度减小时，第一钟形口与产品中的风扇保持预定间距来应付这种高度，当大容量产品的容量增大使产品高度增加时，将第二钟形口额外联结到第一钟形口上，从而补偿风扇和第一钟形口之间的分开距离并保持与风扇的预定间距，使得不管产品容量如何，都可以共同使用第一钟形口并能精确补偿分开距离。As can be clearly seen from the above description, the advantage of the bell mouth device of the ceiling type air conditioner of the present invention is that: when the capacity of the small-capacity product decreases to reduce the height of the product, the first bell mouth and the fan in the product maintain a predetermined distance To cope with this height, when the capacity of large-capacity products increases and the height of the product increases, the second bell mouth is additionally coupled to the first bell mouth, thereby compensating for the separation distance between the fan and the first bell mouth and maintaining The predetermined distance from the fan makes it possible to use the first bell mouth in common and to accurately compensate for the separation distance, regardless of the product volume.
