- the air is formed into a negative pressure through the gap between the door and the window, and is introduced into the room through the gap between the door and the window.
- the second is introduced through the cross-flow impeller inlet air duct or the air inlet negative pressure on the inlet air duct wall.
- the indoor unit heat exchanger is located in the cross flow impeller.

- the mixed air flows out of the indoor unit, and the indoor air outlet temperature is appropriately increased, so that the air outlet of the indoor unit air outlet is changed from a cold wind to a cool air, and the air is soft and comfortable, thereby helping to eliminate the "air conditioning disease".
- the problem is that the mixed air output at this time should be the heat exchange air volume of the cross-flow impeller and the outdoor air volume introduced by the air inlet.

- the present invention introduces the outdoor air through the drain pipe leading to the outdoor through the air duct at the air inlet.
- a drain pipe groove is provided before the air inlet pipe and the drain pipe are connected, and the drainage is provided.
- the tube groove is similar to the curved passage in the sewage pipe, and the accumulated water accumulated on the drain pipe groove 13 blocks the passage between the air inlet pipe and the water receiving plate of the indoor unit, so that the introduction of the outdoor air into the air inlet can be avoided.
- the indoor air of the department is introduced from the water receiving tray through the air inlet duct, so that the efficiency effect of introducing the outdoor air into the air inlet is deteriorated.
- a micro draft fan can be installed on the draft pipe to increase the amount of outdoor air introduced by the draft fan to increase the amount of outdoor air. At the same time, the wind speed increases.
- the air flow velocity on the surface of the water flow in the drain pipe increases, the evaporation speed of the water surface increases, the outdoor air flowing in the drain pipe continuously takes away the water vapor molecules evaporated on the surface of the water flow, and the moisture of the outdoor air is introduced after the water vapor molecules are mixed with the outdoor air. It is further improved, thereby further improving the effect of humidifying the indoor air, solving the problem that the indoor air humidity is reduced and becoming dry, and the introduced outdoor air temperature is decreased more, and the amount of refrigeration brought back to the room is greater. , further improving the energy efficiency of indoor unit refrigeration.
- the outdoor air is introduced into the air duct of the cross-flow impeller through the air duct leading to the outside, and is mixed with the heat exchange air output from the cross-flow impeller to form a soft mixed air flowing out of the indoor air outlet. Since the air volume of the heat exchange air flowing out from the cross-flow impeller is constant, after the mixed air is formed, the total air volume is increased, so the wind speed of the wind is inevitably low, and the range of the wind is also reduced.
- a miniature air-inducing fan is arranged on the air duct, so that the introduced indoor air itself has a certain wind energy, and solves the problem that the wind speed of the wind is low and the range of the wind is reduced, and when the speed of the air-inducing fan is introduced, the wind is introduced.
- the flow rate reaches and is greater than the flow rate of the heat exchange air in the airflow duct of the cross-flow impeller, the wind speed and the wind exit range of the indoor unit to obtain an increased air volume will be equivalent to the heat exchange of the original indoor unit.
- the invention is described in the indoor unit cooling mode.
- the invention can also achieve the purpose of introducing outdoor air in the indoor mechanism heat mode, and the cross flow impeller in the invention is changed into a centrifugal impeller, and other technical features. It is also applied to the air-conditioning indoor unit that enters and exits the air through the centrifugal fan. It is also possible to introduce indoor air to achieve all the objects and effects of the present invention.
- the principle is not substantially different from the above description of the indoor unit through the cross-flow impeller. , do not repeat the description.
- the present invention has the following advantages and positive effects:
- the present invention has the function of humidifying indoor air while introducing outdoor air for indoor fresh air, and solves the problem that the indoor air humidity is reduced and becomes dry.
- the outdoor air temperature introduced by the invention is decreased, and the refrigeration amount in the water flow in the drain pipe is brought back to the indoors, thereby improving the function of the indoor unit refrigeration energy efficiency.
- the technical solution of the invention is simpler and simpler, not only does not need to add a new air duct, but also does not need to add a new air blower, the production cost is lower, and the introduction of outdoor air is more economical for the purpose of changing the indoor air.

现有分体空调包括室外机和室内机,室内机通常采用贯流风机进出风。室内机在工作时,室内空气在贯流风机的作用下被吸入室内机,与热交换器热交换后成为热交换空气,由室内机出风风道返回到室内,如此循环,达到调节室内空气的目的。这存在三个问题:1,室内机制冷模式下室内空气在与热交换器热交换后成为冷热交换空气时,会在换交换器上凝结水珠,水珠滴到接水盘后顺着空调排水管流出室外,使得室内空气湿度不断减少而变得干燥,携带制冷量的水珠被排出室外而浪费制冷量;2,热交换器在使用一段时期后,上面会积满灰尘和细菌,室内空气通过热交器热交换时,会带出灰尘和细菌,使得室内空气变得污浊;3,通常室内是一个密闭的空间,室内空气是不会自动与室外空气发生交换的,人们长时间处在这种环境中,室内空气含氧量会不断下降,大脑会缺氧。由于存在上述三个问题,人们处于这种空调环境中,身心健康就会受到极大的影响,人体感觉很不舒适,久而久之,就有得空调病和心脏血管病的危险。为了解决这三个问题,现有空调通常的解决办法是在空调上设置各种各样的换新风装置,通过引进室外空气,将室内污浊空气逐步置换出去。空调上的换新风装置名目繁多,但基本技术特征都是一样的,就是通过设置贯通室内外的换新风管,换新风管上设置风机,然后引进室外新鲜空气通过门窗等缝隙排出室内污浊空气或排出室内污浊空气通过门窗缝隙引进室外空气,也有的利用现有室内机出风风道风压,将室内污浊空气导出室外再通过门窗等缝隙引进室外空气。这样的换新风装置,引进来的室外空气是可以逐步解决室内空气变得污浊和室内空气含氧量不断下降的问题的,但引进来的室外空气不具有增湿性能,无法解决室内空气湿度减少而变得干燥的问题;也不可能回收热交换器上凝结的水珠排出室外而浪费掉的制冷量,这样的换新风装置,需要增加风管,需要在室内外之间开设让风管通过的风道,需要能引进或排出空气的风机,增加了生产成本和安装成本。专利号为2008200447369,名为“分体空调室内机”的中国专利文献(以下简称D专利)提出一种空调换新风装置,主要技术特征是:在现有空调室内机多组惯流风叶之外,另设换新风风叶和换新风管,换新风管位于换新风风叶的出风风道上,换新风管通过排水管与室外连通,将室内部分空气导出室外,此处的“惯”字应为“贯”,换新风风叶即为贯流叶轮,工作原理是:将室内部分空气导出室外,室内形成负压,室外空气通过门窗等缝隙引进来,达到换新风的目的。但这样引进来的室外空气也不具有增湿功能,同样存在室内空气湿度减少而变得干燥的问题,也不可能回收热交换器上凝结的水珠排出室外而浪费掉的制冷量,换新风管通过排水管与室外连通,倒是省去了增加风管,省去了室内外之间开设让风管通过的风道,但要新增换新风风叶和换新风风叶出风风道,还有要新增D专利没有提到而又必须有的的进风风道(有出风风道就应该有进风风道,否则,换新风风叶运转时形成不了进出风),这样,实际上换新风风叶就是一个与现有室内机上多组贯流风叶共用一台电机的贯流风机,这些都会增加成本,D专利是在现有的空调室内机多组贯流风叶电机转动轴上或多组贯流风叶转动轴上串联换新风风叶的,换新风风叶上还需要设计进出风风道,这就必然增加分体空调室内机的长度,这也会
增加生产成本,因此,D专利存在生产成本增加较大的缺点,D专利是将换新风管通过排水管与室外连通,将室内部分空气导出室外的,现有空调排水管与室内机接水盘相连接而贯通室内,将换新风管通过排水管与室外连通,将室内部分空气导出室外时,导出的室内部分空气仅有一半会排出室外,另一半会顺着排水管到接水盘返回室内,效率效果较差,此外,现有的空调室内机出风风道均为一封闭的风道,热交换空气在被吹出前与出风风道外侧的室内空气是隔绝的,因此,出风风道吹出的全部是热交换风,在制冷模式下,空调室内机进出风温差约为14度左右,室内机出风温度相对室内空气温度,形成较大的温差,当空气调节达到设定温度后,空调处于围绕设定温度间断开启关闭来调控室温的工作状态,室内机的出风温度更低,人体是不宜经受这种室内机出风直吹的,否则就会感觉到很冷,经常受到这种温差过大的室内机出风的直吹,就会得通常所说的“空调病”,这个问题在老幼病弱者身上,在人们睡眠使用时,尤其突出。Existing split air conditioners include outdoor units and indoor units, and indoor units usually use cross-flow fans to enter and exit the wind. When the indoor unit is working, the indoor air is sucked into the indoor unit by the cross-flow fan, and is exchanged with the heat exchanger to become heat-exchanged air, and is returned to the indoor air passage by the indoor unit, so that the indoor air is adjusted. the goal of. There are three problems: 1. When the indoor air in the indoor unit cooling mode becomes hot and cold exchange air after heat exchange with the heat exchanger, the water droplets will be condensed on the exchanger, and the water droplets will drip down to the water tray. The air conditioning drain pipe flows out of the room, so that the indoor air humidity is continuously reduced and becomes dry, and the water droplet carrying the cooling capacity is discharged outside and wastes the cooling capacity; 2. After the heat exchanger is used for a period of time, the dust and bacteria are accumulated thereon. When the indoor air is exchanged by the heat exchanger, it will bring out dust and bacteria, which will make the indoor air become dirty. 3. Usually, the indoor space is a closed space, and the indoor air will not automatically exchange with the outdoor air. In this environment, the oxygen content of the indoor air will continue to drop, and the brain will be deprived of oxygen. Due to the above three problems, people in this air-conditioned environment, physical and mental health will be greatly affected, the human body feels very uncomfortable, over time, there is the danger of air conditioning disease and cardiovascular disease. In order to solve these three problems, the usual solution for the existing air conditioner is to install various kinds of fresh air devices on the air conditioner, and gradually introduce indoor dirty air by introducing outdoor air. There are many new air-conditioning devices on the air conditioner, but the basic technical features are the same. It is to set up a new air duct through the indoor and outdoor, to install a fan on the new air duct, and then introduce outdoor fresh air to discharge the indoor pollution through the gaps such as doors and windows. The air or the dirty air in the exhaust room introduces outdoor air through the gap between the door and window, and some use the wind pressure of the air blower of the existing indoor unit, and the indoor dirty air is led out to the outside and then the outdoor air is introduced through the gap between the door and the window. Such a fresh air device, the introduced outdoor air can gradually solve the problem that the indoor air becomes dirty and the indoor air oxygen content is continuously decreasing, but the introduced outdoor air does not have humidification performance and cannot solve the indoor air humidity reduction. It becomes a problem of drying; it is impossible to recover the amount of cooling that is condensed by the condensed water droplets on the heat exchanger, and such a fresh air device needs to be added with a duct, and it is necessary to open the duct between the indoor and outdoor. The air duct requires a fan that can introduce or discharge air, which increases production costs and installation costs. Patent No. 2008200447369, the Chinese patent document (hereinafter referred to as D patent) named "split air conditioner indoor unit" proposes an air conditioner for fresh air device, the main technical features are: in the existing air conditioning indoor unit, a plurality of sets of inertia blades In addition, a new wind vane and a new air duct are replaced. The new duct is located on the outlet duct of the new wind vane. The new duct is connected to the outside through the drain pipe, and the indoor air is led out to the outside, where The word "habit" should be "continuous", and the new wind blade is a cross-flow impeller. The working principle is: the indoor part of the air is led out to the outside, the room forms a negative pressure, and the outdoor air is introduced through the gaps such as doors and windows to achieve the purpose of changing the fresh air. However, the outdoor air introduced in this way does not have a humidifying function, and there is also a problem that the indoor air humidity is reduced and becomes dry, and it is impossible to recover the amount of cooling that is condensed by the condensation water droplets on the heat exchanger and is wasted. The air duct is connected to the outside through the drain pipe, but the air duct is omitted, and the air duct for allowing the air duct to pass between the indoor and outdoor is omitted, but the new wind vane and the new wind vane air duct are newly added. There is also an air inlet duct that is not mentioned and must be added to the D patent. (There should be an air inlet duct when there is a wind duct, otherwise, the wind and the wind will not form an inlet and outlet when running.) In fact, the new wind blade is a cross-flow fan that shares a motor with multiple sets of cross-flow blades on the existing indoor unit, which will increase the cost. The D patent is to rotate the multi-group cross-flow fan motor in the existing air-conditioning indoor unit. On the shaft or a plurality of sets of cross-flow vane rotating shafts, the new wind vane is connected in series, and the wind and vane are also required to be designed on the new wind vane, which inevitably increases the length of the split air conditioner indoor unit, which will also
Increasing the production cost, therefore, the D patent has the disadvantage of a large increase in production cost. The D patent is to connect the new air duct to the outdoor through the drain pipe, and to export the indoor air to the outdoor. The existing air conditioning drain pipe and the indoor unit are connected to the water. The disk is connected and penetrates the room, and the new air duct is connected to the outdoor through the drain pipe. When the indoor air is led out to the outside, only half of the air in the room will be discharged outside, and the other half will follow the drain pipe to the water tray. Returning indoors, the efficiency effect is poor. In addition, the existing air conditioning indoor air outlet air ducts are all closed air ducts, and the heat exchange air is isolated from the indoor air outside the air outlet ducts before being blown out. All of the air outlets are blown by the heat exchange air. In the cooling mode, the temperature difference between the inlet and outlet of the air conditioner indoor unit is about 14 degrees, and the outlet air temperature of the indoor unit is relatively high compared with the indoor air temperature, forming a large temperature difference. After the temperature is set, the air conditioner is intermittently turned on and off around the set temperature to regulate the working condition of the room temperature. The air temperature of the indoor unit is lower, and the human body is not suitable to withstand such indoors. If the machine blows out the wind, it will feel very cold. If it is often blown by the indoor unit with excessive temperature difference, it will be called the "air conditioning disease". This problem is weak in the old and the young. On the body, it is especially prominent when people use it for sleep.

The object of the present invention is to provide an air conditioning humidification and fresh air indoor unit, which can not only introduce outdoor air, but also solve the problem that indoor air caused by the existing air conditioner indoor unit becomes dirty, without increasing the production cost.

At the same time, it can also improve the indoor air outlet temperature and air volume, and improve the indoor air outlet comfort.
本发明的发明目的是通过以下方式来实现的:一种空调加湿换新风室内机,包括贯流叶轮出风风道,贯流叶轮出风风道壁,其特征是:贯流叶轮出风风道壁上开设有引风口,引风口在垂直于室内机贯流叶轮轴心线,室内机出风口位于左下侧的投影平面中的投影线,与出风风道壁相交的点为上切点的出风风道壁切线正方向段的顺时针夹角大于等于15°到小于等于180°,室内机排水管上连接引风管,引风管另一头管口连接贯通贯流叶轮出风风道壁上开设的引风口,由引风口将室外空气通过通往室外的排水管经引风管导入引进到贯流叶轮出风风道内。The object of the present invention is achieved by the following methods: an air conditioning humidification fresh air indoor unit, including a cross flow impeller air outlet duct, and a cross flow impeller air outlet duct wall, characterized in that: the cross flow impeller wind An air inlet is opened on the wall of the road, the air inlet is perpendicular to the axis of the impeller of the indoor unit, the projection line of the indoor air outlet is located in the projection plane on the lower left side, and the point intersecting the wall of the outlet duct is the upper point The clockwise angle of the positive direction of the tangential wall of the air duct wall is greater than or equal to 15° to 180° or less, and the air duct is connected to the indoor unit drain pipe, and the other end of the air duct is connected to the cross-flow impeller. The air inlet opening on the wall of the road is introduced into the cross-flow impeller air duct by the air inlet through the air outlet pipe leading to the outdoor.
本发明还在引风管与排水管连接贯通之前设置有排水管凹槽。The invention also provides a drain pipe groove before the air inlet pipe and the drain pipe are connected to each other.
空调室内机通常是采用贯流叶轮进出风的,所以贯流叶轮出风风道即为室内机出风风道,贯流叶轮出风风道由出风风道部分的蜗舌和蜗壳以及两侧板组成截面为长方形的出风风道,贯流叶轮的蜗舌和蜗壳就为贯流叶轮出风风道壁,其余两边则为贯流叶轮出风风道侧板,本发明引风口设置在贯流叶轮出风风道壁的蜗壳上,即通常所称的贯流叶轮的出风风道壁后蜗壳上,因此,本发明的贯流叶轮出风风道壁上开设有引风口即为贯流叶轮出风风道壁的蜗壳上开设有引风口,贯流叶轮为长圆筒形,贯流叶轮的出风风道截面为长方形,室内机的出风口的截面也为为长方形,贯流叶轮的轴心线与上述长方形的长中心线平行,所以贯流叶轮出风风道壁上开设的引风口也相对应为长中心线与之平行的长方形,请参见附图2,附图3,组成长方形的引风口在垂直于室内机贯流叶轮轴心线,室内机出风口位于左下侧的投影平面中的投影线,以贯流叶轮出风风道出风方向151为方向,沿着出风风道壁14,首先与出风风道壁14相交的点为与出风风道壁相交的上切点A,对应的另一切点则为与出风风道壁14相交的下切点B,与出风风道壁14相交的上切点A所在的直线为长方形引风口上长边18,出风风道壁相交的下切点B所在的直线为长方形引风口下长边19,上下长边与贯流叶轮出风风道侧板围成长方形引风口,长方形引风口也可设计成一块长方形面板,在面板上开设圆形,椭圆形,正方形等其他形状的引风洞口,只要这些引风洞口所在的面板
满足在垂直于室内机贯流叶轮轴心线,室内机出风口位于左下侧的投影平面中的投影线,与出风风道壁相交的点为上切点的出风风道壁切线正方向段的顺时针夹角大于等于15°到小于等于180°即可。开设圆形,椭圆形,正方形等其他形状引风洞口的长方形面板与长方形引风口实质上是相同的。The air-conditioning indoor unit usually adopts a cross-flow impeller to enter and exit the wind, so the cross-flow impeller air outlet duct is the indoor unit air outlet duct, and the cross-flow impeller air outlet duct is composed of the volute tongue and the volute of the air duct portion and The two sides of the plate form a rectangular air outlet duct, the volute tongue and the volute of the cross flow impeller are the cross flow impeller air outlet duct wall, and the other two sides are the cross flow impeller air duct side plate, the present invention The tuyere is disposed on the volute of the cross-flow impeller air outlet duct wall, that is, the so-called cross-flow impeller is disposed on the rear volute of the air duct wall, and therefore, the cross-flow impeller air outlet duct wall of the present invention is opened. There is an air inlet at the volute of the air duct wall of the cross-flow impeller, and the cross-flow impeller has a long cylindrical shape. The cross-section of the cross-flow impeller has a rectangular cross section, and the cross section of the air outlet of the indoor unit is also In order to be a rectangle, the axial line of the cross-flow impeller is parallel to the long center line of the above-mentioned rectangle, so the air inlet opening on the wind tunnel wall of the cross-flow impeller is correspondingly a rectangle parallel to the long center line, see attached Figure 2, Figure 3, the rectangular air vents are perpendicular to the room The cross-flow impeller axis line, the projection line of the indoor unit air outlet located in the lower left projection plane, with the cross-flow impeller air duct wind direction 151 as the direction, along the outlet duct wall 14, first and the outlet The point where the duct wall 14 intersects is the upper tangent point A intersecting the outlet duct wall, and the corresponding other tangent point is the lower tangent point B intersecting the outlet duct wall 14, intersecting the outlet duct wall 14. The straight line where the upper cutting point A is located is the long side 18 of the rectangular air inlet, and the line where the lower cutting point B intersecting the wind tunnel wall is the long side 19 of the rectangular air inlet, and the upper and lower long sides and the cross flow impeller air outlet side The board encloses a rectangular air inlet, and the rectangular air inlet can also be designed as a rectangular panel. The panel is provided with circular, elliptical, square and other shapes of the wind tunnel, as long as the panel of the wind tunnel is located.
The projection line in the projection plane perpendicular to the axial direction of the indoor flow impeller, the indoor air outlet is located on the lower left side, and the point intersecting the outlet air duct wall is the upper end of the tangential line of the outlet duct wall The clockwise angle of the segment is greater than or equal to 15° to less than or equal to 180°. A rectangular panel with circular, elliptical, square, and other shapes of the inlet opening is substantially the same as the rectangular air inlet.
本发明垂直于室内机贯流叶轮轴心线,室内机出风口位于左下侧的投影平面即为空调室内机右视图,也就是本发明附图1,反之,则为空调室内机左视图。室内机出风口位于左下侧即贯流叶轮出风方向为左下侧。The invention is perpendicular to the axial center of the indoor flow impeller, and the projection plane of the indoor air outlet on the lower left side is the right side view of the air conditioner indoor unit, that is, FIG. 1 of the present invention, and vice versa, the left side view of the air conditioner indoor unit. The outlet of the indoor unit is located on the lower left side, that is, the direction of the cross-flow impeller is the lower left side.
室内机贯流叶轮折射出风的特性决定了出风风道不同于一般的风机出风风道,一般的风机出风风道技术并不适用于贯流叶轮出风风道的设计,只要在贯流叶轮进风风道上接上换新风管或在进风风道壁上开风口接上换新风管就会导入引风,贯流叶轮出风风道上接上换新风管或在出风风道壁上开风口接上换新风管就会导出出风,这是公知常识,D专利的换新风管位于所述新风风叶的出风通道上将室内部分空气导出室外就是利用了这一常识,D专利的换新风管就是本发明中的引风管。本发明的特点是在通常开设风口只能导出出风的贯流叶轮的出风风道壁上开设能够导入引风的风口,贯流叶轮的出风风道壁的型线为对着贯流叶轮轴心线方向弧形弯曲,如仅是在原来的出风风道壁上简单开一个风口,贯流叶轮流出的空气将会直接对着风口在风口形成正压而导出出风,是不可能导入引进室外空气的,所以必须将风口的上切点与下切点所组成的投影线在出风风道壁上的相对位置结构关系满足“引风口在垂直于室内机贯流叶轮轴心线,室内机出风口位于左下侧的投影平面中的投影线,与出风风道壁相交的点为上切点的出风风道壁切线正方向段的顺时针夹角大于等于15°到小于等于180°”这一技术特征才能形成负压引风口,请参见附图3,上切点A到下切点B的连线即为上切点与下切点所组成的投影线,与出风风道壁相交的点为上切点的出风风道壁切线是指以上切点A为切点,以上切点所在的出风风道壁14型线在上切点A为切点的切线,即附图3中的101,附图3中的151为贯流叶轮出风方向,切线101箭头方向即表示为切线与贯流叶轮出风方向151同方向,过切线上切点A与贯流叶轮出风方向151同方向的线段即为切线正方向段,反之,则为切线负方向段。顺时针夹角是指上切点A到下切点B的连线以上切点A为原点,顺时针方向转到与该切线正方向段的夹角,即附图3中102,102中的箭头方向标明为顺时针。如果在空调室内机左视图中,顺时针夹角则为逆时针夹角,两者性质相同。当出现出风风道壁的型线为直线的特例时,出风风道壁型线所形成的直线即为上切点A所在的出风风道壁切线。当引风口的上切点到引风口的下切点在出风风道壁上满足这样的位置结构关系时,引风口就能形成负压区域,引风口就会将室外空气通过通往室外的排水管经引风管导入引进到贯流叶轮出风风道内,与贯流叶轮输出的热交换空气混合后形成混合风流出室内机出风口而流往室内,引进了室外空气,室内空气量增加,形成正压,室内空气就会通过门窗等缝隙流出室外,如此不断交换,就实现了本发明的室内机换新风的发明目的。否则,由于出风风道是向着贯流叶轮轴心线方向弧形弯曲的,贯流叶轮折射流出的热交换空气就不能保证在引风口形成负压,有可能形成引风与出风同时出现的情况,甚至形成热交换空气通过引风口流出室外而不能引入室外空气的情况,发明目的不但无法实现,还费电耗能,延长空调制冷时间。The characteristics of the indoor unit's cross-flow impeller refracting the wind determine that the wind duct is different from the general fan duct. The general fan duct air duct technology is not suitable for the design of the cross-flow impeller duct. The cross-flow impeller inlet air duct is connected with a new air duct or the air inlet of the air inlet duct is connected with the new air duct, and the air duct is introduced, and the cross-flow impeller air duct is connected with the new air duct or It is common knowledge to connect the open air outlet on the air outlet wall to the new air duct. This is common knowledge. The patented new air duct of D is located on the air outlet of the new wind vane to direct the indoor air to the outside. Taking advantage of this common sense, the new air duct of the D patent is the air duct in the present invention. The invention is characterized in that a tuyere capable of introducing an induced draft is opened on an outlet duct wall of a cross-flow impeller which usually only has an air outlet, and an air duct wall of the cross-flow impeller is opposed to the cross flow. The axial direction of the impeller is curved curved. For example, only a tuyere is simply opened on the original air outlet duct wall. The air flowing out from the cross-flow impeller will directly form a positive pressure against the tuyere at the tuyere. It is possible to introduce the introduction of outdoor air, so the relative positional relationship between the upper cut point of the tuyere and the lower cut point on the air duct wall must be satisfied. The air intake is perpendicular to the axis of the indoor cross flow impeller. The projection line in the projection plane of the indoor unit air outlet is located on the lower left side, and the point intersecting the outlet air duct wall is the clockwise angle of the positive direction of the tangential line of the outlet duct wall of the upper cut point is greater than or equal to 15° to less than The technical feature of equal to 180° can form a negative pressure air inlet. Referring to Figure 3, the line connecting the upper point A to the lower point B is the projection line composed of the upper and lower points, and the wind. The point where the wall intersects is the wind of the upper cut point The wall tangential line refers to the above-mentioned tangent point A as the tangent point, and the tangential line of the outlet duct wall 14 where the above cut point is located is the tangent of the tangent point at the upper tangent point A, that is, 101 in FIG. 3, 151 in FIG. For the direction of the cross-flow impeller, the direction of the tangential line 101 is the same direction as the tangential direction of the cross-flow impeller, and the line between the tangent point A on the over-cut line and the direction 151 of the cross-flow impeller is the tangential direction. The segment, on the other hand, is the tangential negative direction segment. The clockwise angle refers to the line connecting the upper cutting point A to the lower cutting point B. The cutting point A is the origin, and the clockwise direction is turned to the angle with the positive direction of the tangent line, that is, the arrow in 102, 102 in FIG. The direction is marked as clockwise. If in the left view of the air conditioner indoor unit, the clockwise angle is the counterclockwise angle, and the two properties are the same. When the profile of the wind tunnel wall is a straight line, the straight line formed by the wind duct wall profile is the cut line of the outlet duct wall where the upper cut point A is located. When the upper cut point of the air inlet to the lower cut point of the air inlet meets such a positional relationship on the wind tunnel wall, the air inlet can form a negative pressure region, and the air inlet passes the outdoor air through the drainage to the outdoor. The pipe is introduced into the cross-flow impeller air duct by the introduction of the air duct, and is mixed with the heat exchange air output from the cross-flow impeller to form a mixed air flowing out of the indoor air outlet and flowing into the room, introducing outdoor air, and the indoor air volume is increased. When a positive pressure is formed, the indoor air flows out of the room through a gap such as a door or window, and the exchange of the air continuously realizes the object of the invention for replacing the fresh air of the indoor unit of the present invention. Otherwise, since the outlet air duct is curved curved toward the axial direction of the cross-flow impeller, the cross-flow impeller refracts the heat exchange air flowing out to ensure that a negative pressure is formed at the air inlet, and it is possible to form both the induced and the outgoing air. In the case, even if the heat exchange air flows out of the outdoor air through the air inlet, and the outdoor air cannot be introduced, the object of the invention is not only impossible to realize, but also consumes electricity and energy, and prolongs the air conditioning cooling time.
空调室内机制冷时,热交换器上会凝结水珠,水珠滴落在接水盘后汇集成水流顺着排水管流出室外,而引风口将室外空气通过通往室外的排水管经引风管导入引进贯流叶轮出风风道内时,引进的室外空气流动方向与顺着排水管流出
室外的水流流动方向相反,顺着排水管流出室外的水流表面在任何情况下都会发生汽化蒸发现象,逆向流经水流的室外空气就不断带走水流表面的水汽分子,水流表面空气流动速度越大,水面的蒸发速度越快,通常的排水管直径较小,排水管中流动的室外空气流速较大,不断带走水流表面的水汽分子就多,水汽分子与室外空气混合后就提高了引进的室外空气的湿度,提高了湿度的室外空气与室内空气混合后,从而达到为室内空气加湿,解决室内空气湿度减少而变得干燥问题的发明目的。When the air conditioner indoor unit is cooled, water droplets will condense on the heat exchanger, and the water droplets will drip into the water tray and then collect into a water stream flowing out of the drain pipe outside the drain pipe, and the air inlet port will pass the outdoor air through the drain pipe leading to the outdoor air. When the pipe is introduced into the cross-flow impeller air outlet duct, the introduced outdoor air flow direction flows out along the drain pipe.
The outdoor water flow direction is opposite. The surface of the water flowing out of the drain pipe will vaporize and evaporate under any circumstances. The outdoor air flowing backwards through the water will continuously take away the water vapor molecules on the surface of the water flow. The air flow speed on the surface of the water flow is higher. The faster the evaporation rate of the water surface is, the smaller the diameter of the ordinary drainage pipe is, the larger the flow rate of the outdoor air flowing in the drainage pipe is, and the more the water vapor molecules are continuously taken away from the surface of the water flow. The mixing of the water vapor molecules with the outdoor air improves the introduction. The humidity of the outdoor air is increased by mixing the outdoor air with the indoor air to achieve the purpose of humidifying the indoor air and solving the problem that the indoor air humidity is reduced and becomes dry.
在制冷模式下的热交换器上会凝结水珠,凝结的水珠也包含一定的制冷量,这部分能量,随着在排水管中被排出室外的水流而损失浪费掉,但逆向流经水流的室外空气不断带走水流表面的水汽分子与室外空气混合后进入室内的同时,会使得引进的室外空气温度有所下降,一部分制冷量也就被带回重返室内,提高了室内机制冷能效。In the cooling mode, the water droplets will condense, and the condensed water droplets also contain a certain amount of cooling. This part of the energy is lost and wasted with the water flowing out of the drain pipe, but flows backward through the water flow. The outdoor air continuously takes away the water vapor molecules on the surface of the water and mixes with the outdoor air and enters the room. At the same time, the temperature of the introduced outdoor air is reduced, and part of the cooling capacity is brought back to the room to improve the energy efficiency of the indoor unit. .
本发明是在原有室内机贯流叶轮出风风道壁上开设特定结构的风口,利用原有室内机贯流叶轮出风的风压使得风口成为引风口而具有了负压吸风的功能,从而才能将室外空气通过连接引风口的引风管和排水管吸引进来,所以引风管上无需另设引风风机就能达到了换新风的目的,真正的省去换气风机,而D专利中的换新风风叶其实就是一个与现有室内机多组惯流风叶共用一台电机的贯流风机,换新风是需要通过新设的换新风风叶(贯流风机)才能实现的。本发明不但省去换气风机,而且引风管路大部分与排水管共用,在贯流叶轮出风风道壁上开设的引风口可以在贯流叶轮出风风道壁注塑成型生产的同时生成,生产成本几乎没有增加,因此,本发明可以在几乎不增加生产成本的情况下实施。The invention is to open a tuyere of a specific structure on the wall of the original indoor cross-flow impeller air outlet duct, and the wind pressure of the wind generated by the original indoor unit cross-flow impeller makes the tuyere become the air inlet and has the function of suctioning the negative pressure. Therefore, the outdoor air can be sucked in through the air inlet pipe and the drain pipe connected to the air inlet, so that the air inlet pipe can be used for the purpose of changing the fresh air without the need of a separate air draft fan, and the ventilation fan is truly omitted, and the D patent The new wind blade is actually a cross-flow fan that shares a motor with multiple sets of inertia blades in the existing indoor unit. The new wind is required to be replaced by a new wind turbine (cross-flow fan). The invention not only saves the ventilation fan, but also the air intake pipeline is mostly shared with the drain pipe, and the air inlet opening on the wind tunnel wall of the cross flow impeller can be injection molded and produced in the wind tunnel wall of the cross flow impeller. With the production, the production cost hardly increases, and therefore, the present invention can be carried out with little increase in production cost.
本发明是在贯流叶轮出风风道壁上开设特定结构设计的引风口,才使得引风口具有了负压吸风的功能,连接引风口的引风管和排水管才能将室外空气导入引进来,才会使得引进的室外空气流动方向与顺着排水管流出室外的水流流动方向相反,才会产生为室内空气加湿,解决室内空气湿度减少而变得干燥问题和引进的室外空气温度有所下降,排水管水流中的制冷量被带回室内,提高室内机制冷能效的作用,否则,如D专利提出的技术方案那样,虽然“所述新风管通过排水管与室外连通”,“将排水管与排风管合二为一”,但“换新风管住于所述新风风叶的出风通道上”,就必然是“将室内部分空气导出室外”,此处排风管即为换新风管,很显然,不可能是引风管。“将室内部分空气导出室外”,室内空气量减少,室内形成负压,室外空气就通过门窗等缝隙流进室内达到引进室外空气的目的,导出室外的室内空气流动方向与顺着排水管流出室外的水流流动方向相同,都是排出室外,所以不可能产生为室内空气加湿,解决室内空气湿度减少而变得干燥问题和引进的室外空气温度有所下降,制冷量被带回重返室内,提高室内机制冷能效的功能,而通过门窗等缝隙直接流进室内的室外空气当然也不可能具备“为室内空气加湿”和“提高室内机制冷能效”的功能。The invention is to open a drafting structure with a specific structure design on the wall of the cross-flow impeller air outlet, so that the air inlet has the function of suctioning the negative pressure, and the air inlet pipe and the drain pipe connecting the air inlet can introduce the outdoor air into the introduction. In order to make the outdoor air flow direction opposite to the flow direction of the water flowing out of the drain pipe, the indoor air humidification will be generated, the indoor air humidity will be reduced and the dry air problem will be solved, and the introduced outdoor air temperature will be increased. Decrease, the cooling capacity in the water flow of the drain pipe is brought back to the room to improve the energy efficiency of the indoor unit refrigeration. Otherwise, as the technical solution proposed by the D patent, although the new air duct is connected to the outside through the drain pipe, The drain pipe and the exhaust pipe are combined into one, but the "new air pipe is placed on the air outlet of the new wind blade", which is necessarily "exporting part of the indoor air to the outside", where the exhaust pipe is With a new duct, it is obvious that it is impossible to introduce the duct. “Exporting part of the indoor air to the outside”, the indoor air volume is reduced, and the indoors form a negative pressure. The outdoor air flows into the room through the gaps such as doors and windows to achieve the purpose of introducing outdoor air, and the outdoor indoor air flow direction is discharged and flows out along the drain pipe. The flow direction of the water flow is the same, and it is discharged outside, so it is impossible to humidify the indoor air, solve the problem that the indoor air humidity is reduced and become dry, and the introduced outdoor air temperature is decreased, and the cooling capacity is brought back to the room to improve. The indoor unit has the function of cooling energy efficiency, and the outdoor air that flows directly into the room through gaps such as doors and windows is of course impossible to have the functions of “humidifying indoor air” and “increasing indoor unit cooling energy efficiency”.
空调制冷工作时,室外空气的温度大于室内空气温度,更大于贯流叶轮输出的热交换空气温度,现有空调换新风装置引进来的室外空气,有两种途径进入室内:一是导出室内污浊空气使室内形成负压后通过门窗等缝隙导入进来直送室内,二是通过贯流叶轮进风风道或进风风道壁上的风口负压引进,通常室内机的热交换器位于贯流叶轮进风风道上,负压引进的室外空气与贯流叶轮进风风道引进的室内空气混合后由热交换器热交换经贯流叶轮到出风风道形成出风送入室内,此时的室外空气已成为热交换空气了,因此,无论室外空气那一种途径进入室内,都不会产生提高室内机出风温度的影响。本发明引进的室外空气是避开热
交换器直接进入贯流叶轮出风风道的,尽管室外空气因逆向流经排水管中的水流使得温度有所下降,但仍远高于贯流叶轮输出的热交换空气温度,当贯流叶轮出风风道壁上的引风口将室外空气通过通往室外的排水管经引风管导入引进贯流叶轮出风风道内,与贯流叶轮输出的热交换空气混合后就会形成温度得到提高的混合空气流出室内机,室内机出风温度得到适当提高,使得室内机出风口的出风由人体感觉冷风变为凉风,出风变得柔和舒适,从而有助于消除“空调病”的问题,此时的混合风出风量应为贯流叶轮的热交换出风量加引风口引进来的室外空气量,总出风量加大,制冷量不减还略有增加,为贯流叶轮流出来的热交换出风所携带的制冷量与引进的室外空气带回的制冷量之和,制冷量略增,出风量增加,室内空气循环加速,达到设定温度所需的时间减少,省电节能。During air conditioning and refrigeration operation, the outdoor air temperature is greater than the indoor air temperature, which is greater than the heat exchange air temperature output by the cross flow impeller. The outdoor air introduced by the existing air conditioning and fresh air device has two ways to enter the room: one is to export indoor pollution. The air is formed into a negative pressure through the gap between the door and the window, and is introduced into the room through the gap between the door and the window. The second is introduced through the cross-flow impeller inlet air duct or the air inlet negative pressure on the inlet air duct wall. Usually, the indoor unit heat exchanger is located in the cross flow impeller. On the inlet air duct, the outdoor air introduced by the negative pressure is mixed with the indoor air introduced by the cross-flow impeller inlet air duct, and then heat exchanged by the heat exchanger through the cross-flow impeller to the air outlet duct to form an air blow into the room. The outdoor air has become heat exchanged air. Therefore, no matter whether the outdoor air enters the room, there is no effect of increasing the temperature of the indoor unit. The outdoor air introduced by the invention is to avoid the heat
The exchanger directly enters the cross-flow impeller air outlet duct. Although the outdoor air flows downward due to the flow of water in the drain pipe, the temperature is lowered, but it is still much higher than the heat exchange air temperature output from the cross-flow impeller. The air inlet on the wall of the air outlet duct introduces the outdoor air into the air duct of the cross-flow impeller through the air duct leading to the outdoor, and the temperature is improved after mixing with the heat exchange air output from the cross-flow impeller. The mixed air flows out of the indoor unit, and the indoor air outlet temperature is appropriately increased, so that the air outlet of the indoor unit air outlet is changed from a cold wind to a cool air, and the air is soft and comfortable, thereby helping to eliminate the "air conditioning disease". The problem is that the mixed air output at this time should be the heat exchange air volume of the cross-flow impeller and the outdoor air volume introduced by the air inlet. The total air volume is increased, the cooling capacity is not reduced, and the cross-flow impeller flows out. The sum of the cooling capacity carried by the heat exchange and the amount of refrigeration brought back by the introduced outdoor air, the cooling capacity is slightly increased, the air volume is increased, the indoor air circulation is accelerated, and the required temperature is reached. Between the reduced energy saving.
D专利将换新风管通过排水管与室外连通,导出的室内部分空气仅有一半会排出室外,效率效果差,本发明在引风口将室外空气通过通往室外的排水管经引风管导入引进贯流叶轮出风风道内,与贯流叶轮输出的热交换空气混合后形成柔和舒适的混合空气流出室内机出风口时,在引风管与排水管连接贯通之前设置排水管凹槽,排水管凹槽类似排污管道中的弯通,通过排水管凹槽13上蓄积的积水阻断引风管与室内机接水盘之间的通道,这样,就可避免出现引风口引入室外空气时会通过引风管由接水盘引入部门室内空气,使得引风口引入室外空气的效率效果变差的问题。如果还需要提高引进的室外空气量,可在引风管上设置微型引风风扇,通过引风风扇增大引风风能的办法,来进一步提高引进室外空气量,与此同时,引风风速增大,排水管内的水流表面空气流动速度增大,水面的蒸发速度增快,排水管中流动的室外空气不断带走水流表面蒸发的水汽分子增多,水汽分子与室外空气混合后引进室外空气的湿度得到进一步提高,从而进一步提高了为室内空气加湿,解决室内空气湿度减少而变得干燥问题的效果,而且引进的室外空气温度下降得更大,制冷量被带回重返室内的量就更大,进一步提高了室内机制冷能效。The patent D connects the fresh air duct to the outdoor through the drain pipe, and only half of the air in the room is discharged outside, which is inefficient. The present invention introduces the outdoor air through the drain pipe leading to the outdoor through the air duct at the air inlet. When the cross-flow impeller air outlet duct is introduced and mixed with the heat exchange air output from the cross-flow impeller to form a soft and comfortable mixed air flowing out of the indoor unit air outlet, a drain pipe groove is provided before the air inlet pipe and the drain pipe are connected, and the drainage is provided. The tube groove is similar to the curved passage in the sewage pipe, and the accumulated water accumulated on the drain pipe groove 13 blocks the passage between the air inlet pipe and the water receiving plate of the indoor unit, so that the introduction of the outdoor air into the air inlet can be avoided. The indoor air of the department is introduced from the water receiving tray through the air inlet duct, so that the efficiency effect of introducing the outdoor air into the air inlet is deteriorated. If it is necessary to increase the amount of outdoor air to be introduced, a micro draft fan can be installed on the draft pipe to increase the amount of outdoor air introduced by the draft fan to increase the amount of outdoor air. At the same time, the wind speed increases. Large, the air flow velocity on the surface of the water flow in the drain pipe increases, the evaporation speed of the water surface increases, the outdoor air flowing in the drain pipe continuously takes away the water vapor molecules evaporated on the surface of the water flow, and the moisture of the outdoor air is introduced after the water vapor molecules are mixed with the outdoor air. It is further improved, thereby further improving the effect of humidifying the indoor air, solving the problem that the indoor air humidity is reduced and becoming dry, and the introduced outdoor air temperature is decreased more, and the amount of refrigeration brought back to the room is greater. , further improving the energy efficiency of indoor unit refrigeration.
在引风口将室外空气通过通往室外的排水管经引风管导入引进贯流叶轮出风风道内,与贯流叶轮输出的热交换空气混合后形成柔和的混合风流出室内机出风口时,由于贯流叶轮流出的热交换空气的风量是一定的,形成混合风后,总出风量增加了,所以出风风速就必然有所隆低,出风射程也有所减小,此时,在引风管上设置微型引风风扇,使得导入引进的室内空气自身具有了一定的风能,解决了出风风速有所隆低,出风射程有所减小的问题,当引风风扇转速使得引进风的流速达到和大于贯流叶轮出风风道内热交换空气的流速时,室内机获得增大的出风量的出风风速和出风射程将会与原室内机热交换出风相当。At the air inlet, the outdoor air is introduced into the air duct of the cross-flow impeller through the air duct leading to the outside, and is mixed with the heat exchange air output from the cross-flow impeller to form a soft mixed air flowing out of the indoor air outlet. Since the air volume of the heat exchange air flowing out from the cross-flow impeller is constant, after the mixed air is formed, the total air volume is increased, so the wind speed of the wind is inevitably low, and the range of the wind is also reduced. A miniature air-inducing fan is arranged on the air duct, so that the introduced indoor air itself has a certain wind energy, and solves the problem that the wind speed of the wind is low and the range of the wind is reduced, and when the speed of the air-inducing fan is introduced, the wind is introduced. When the flow rate reaches and is greater than the flow rate of the heat exchange air in the airflow duct of the cross-flow impeller, the wind speed and the wind exit range of the indoor unit to obtain an increased air volume will be equivalent to the heat exchange of the original indoor unit.
本发明是以室内机制冷模式下作出说明的,同样的道理,本发明在室内机制热模式下同样可以达到引进室外空气的目的,将本发明中的贯流叶轮改为离心叶轮,其他技术特征不变地应用在通过离心风机进出风的空调室内机上,也同样可以引进室内空气达到本发明的所有发明目的和功效,其原理与上述通过贯流叶轮进出风的室内机作出的说明没有实质区别,对此不作重复说明。The invention is described in the indoor unit cooling mode.
