Description

Split wall air conditioner

Technical field

The invention belongs to the technical field of air conditioning, and relates only to a split wall-mounted air conditioner which uses a cross-flow fan for heat exchange.

Background technique

Split wall-mounted air conditioners include indoor units and outdoor units. The indoor unit is mainly composed of a heat exchanger and a cross flow fan. The cross-flow fan mainly comprises a cross-flow impeller and a volute, and the volute of the wind-flow part of the cross-flow fan constitutes a wind duct, and the volute forming the wind duct is an outlet duct wall. During air conditioning operation, the indoor air is sucked into the indoor unit under the action of the cross-flow impeller, and is heat-exchanged by heat exchange with the heat exchanger, and then passes through the cross-flow impeller, and is blown out by the indoor air outlet duct. The air outlet ducts of the existing split-wall air-conditioning indoor unit cross-flow impellers are all closed air passages having a rectangular cross section, and the heat exchange air is isolated from the indoor air outside the air outlet duct before being blown out. Therefore, all of the air outlet ducts are blown by the heat exchange air. Especially in the cooling mode, the temperature difference between the inlet and outlet of the split-wall air-conditioning indoor unit is about 14 degrees. The heat exchange of such a large temperature difference produces a large temperature difference with respect to the original indoor air temperature. After the air conditioner is adjusted to the set temperature, 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. If the human body is subjected to the direct blow of the indoor unit, it will be felt. It’s very cold, and it’s often called “air conditioning sickness” when it’s blown out by the indoor unit with too much temperature difference. This problem is caused by people who are sick and sick, children, when people sleep. Especially outstanding. In order to solve this problem, it is necessary to provide a mixed air supply device to improve the temperature difference between the indoor unit air and the indoor air. However, the characteristics of the cross-flow fan in the indoor unit determine that the wind duct should be designed to be as narrow as possible. The cost reduction and aesthetics of the indoor unit also require a miniaturized design. Therefore, the air duct of the cross-flow fan cannot be designed. The normal air supply device is accommodated. Otherwise, the air supply device is forcibly set, and the air outlet air passage is blocked, which seriously affects the wind pressure and the air output. For a long time, those skilled in the art of air conditioning technology have always believed that an air supply device cannot be provided in an indoor air duct having a cross-flow fan for heat exchange. For example, the Chinese patent No. CN203857578U, the first page of the patent specification entitled “An Air Conditioner” clearly states that “the existing air conditioners with installation parts generally use cross-flow fans, cross-flow fans, air ducts and air outlets. The positional relationship determines that it is difficult to provide an additional air supply device therein." The cross flow fan here is a cross flow impeller. Therefore, the technicians in the field of air conditioning always put the design of the air supply device on the outside of the air outlet of the indoor unit, and set up a wide variety of air guiding and air blowing devices, such as upper and lower air guiding, left and right air guiding, There are also thousands of patented technical documents for the air-conducting air supply device on the outside of the indoor air outlet. The purpose is to improve the temperature difference in the area and reduce the problem of direct blowing. Chinese patent number CN204301261U, the patent entitled "a split wall-mounted air conditioner" (referred to as D patent) proposed on the rear volute of the air duct of the cross-flow fan, that is, the air supply duct wall is set to send The air device is introduced into the indoor air supply duct by introducing air that has not been exchanged in the air and forming a mixed air with the heat exchange air in the air supply duct, and the technical solution is mainly on the air duct wall. Opening and installing a wind guiding component at the opening, forming an additional air inlet at a corresponding position of the indoor casing, the air guiding component is as described in the natural paragraph of the patent specification 0008, 0009: the air guiding component is a plurality of guiding styles a grid, the "leading style grid includes a first portion on the rear volute profile line and a second portion that is curved away from the supply air duct". Obviously, the D patented air intake assembly is also disposed The outer side of the wind duct wall. The purpose of the invention of the D patent is twofold: 1. The mixed air with a small temperature difference between the air supply duct and the room is sent to the room, and the mixed air with a small temperature difference is blown onto the human body, feeling cool and not cold, and is soft and comfortable. , to improve the user's comfort experience; 2, increase the air volume of the indoor unit air outlet, help speed up the indoor air flow speed and uniformity, reduce the time and energy required for the indoor air to reach the set temperature Consumption. However, the technical solution of the D patent has three shortcomings: 1. The space formed by the outside of the air duct wall of the air-conditioning indoor unit and the indoor unit casing is the only air-conditioning connecting pipe and air-conditioning drain pipe that can be used to set the insulation pipe package. And the power line connected to the outdoor unit, the tubes and lines almost occupy the space outside the wall of the wind duct and close to the outside of the wind duct wall of the cross-flow fan, and the existing air-conditioned indoor unit comes from aesthetics and cost saving. In other words, they tend to be ultra-thin and miniaturized. After ultra-thin and miniaturized design, this space is even narrower. It has become very difficult to set these pipes and wires in this narrow space. Therefore, the cross-flow fan is out of the wind. There is no extra space on the outside of the road wall to accommodate the air intake component. Even if the air intake component is forcibly set, the air inlet of the air intake component will be surrounded by the air conditioning connecting pipe wrapped by the heat insulating pipe, and the air conditioning drain pipe and the power cable will be blocked by the air conditioner. If the wind is not smooth, it is difficult to ideally achieve the technical effect of the first invention of the D patent. The natural section of the third page of the D patent specification emphasizes that the opening 71 must be limited to the rear. Suitable location of a particular segment of the housing 7 and defining openings at both ends of the distance has been fully described this problem patented D technical solution. 2, as the first line of the second page of the D patent specification refers to the first line of the third page, the additional air inlet is far away from the air outlet to avoid the problem that the air outlet of the indoor air outlet is recirculated through the additional air inlet. The thickness of the machine, that is, the dimension perpendicular to the wall, has been generally 300MM thick from the early years, and the thin design has been designed to the current 135MM-200MM. The additional air inlet is designed on the indoor casing to be farther away from the air outlet. It is impossible to exceed the thickness of the indoor unit. One inlet and one air inlet are only 135MM-200MM apart, especially the inlet and outlet air inlet and outlet angles are less than 90°, and the backflow problem cannot be avoided. This recirculation area of the wall-mounted air conditioner is located at the lower edge of the indoor unit, usually away from the active area of the person in the room, and the backflow causes the air volume of the indoor unit to be blown to the indoor activity area of the indoor person who usually needs air conditioning to be reduced, and the amount of air output is reduced for the target area. Therefore, the D patent can not only reduce the time and energy consumption required for the indoor air to reach the set temperature, but also it is difficult to achieve the technical effect of the second invention of the D patent. 3. Nowadays, the competition in the air-conditioning market is becoming increasingly fierce, and the profit of air-conditioning has become increasingly meager. The patented technical solution of D has to achieve the purpose of invention by increasing the air-inducing components and additional air inlets, which will increase the cost and will inevitably reduce the competitiveness of products due to the increase of production costs. .

Summary of the invention

1. The object of the present invention is to provide a split wall-mounted air conditioner, which solves the problem that the existing wall-mounted air conditioner is not soft enough, and the air supply volume is small, that is, the D patent invention is completely achieved, and the D patent is solved. The induced air intake component has poor air induction effect and the additional air inlet brings more serious backflow problems.

2. The invention can be implemented without increasing the production cost on the basis of the existing air conditioner indoor unit, and the market competitiveness of the product is improved.

The object of the present invention is achieved by a split wall-mounted air conditioner including a cross flow fan in an indoor unit and a cross flow fan air outlet wall, which is characterized in that: the wind of the cross flow fan A tuyere is opened on the wall of the road, and the upper end and the lower end of the tuyere are staggered to form an air guiding opening, and the connecting line between the upper end and the lower end is located at the origin of the plane orthogonal coordinate system, and the angle is 30° in the positive direction of the X axis. The fan-shaped section formed by rotating the starting line counterclockwise from 0° to 210°.

The object of the present invention can also be achieved by the split wall-mounted air conditioner as described above, and the air outlet is provided on the mounting plate on the rear side of the indoor unit casing.

Generally, the cross-flow fan impeller has a long cylindrical shape, and the cross-flow duct on the cross-flow fan volute has a rectangular cross section, and the air outlet of the indoor unit has a rectangular cross section, and the axial center line of the cross-flow fan impeller and the long center line of the rectangular shape. Parallel, so the tuyere opened on the outlet duct wall of the cross-flow fan is also corresponding to the rectangle with the long center line parallel thereto. The two long ends forming the rectangular tuyere are in the order of the flow direction of the cross-flow impeller to the outlet of the indoor unit. First, the long side of the rectangular tuyere on the wall of the outlet duct is the upper end, and the other long side corresponding thereto Then it is the lower end.

Since the shape of the outlet duct of the cross-flow fan is curved in the direction of the axis of the cross-flow fan impeller, if only a rectangular tuyere is opened on the original outlet duct wall, the two long sides of the rectangular tuyere are still located. On the wall of the outlet duct, the air flowing out from the impeller of the cross-flow fan will directly flow out at the tuyere against the tuyere, and it is impossible to achieve the purpose of introducing indoor air. Therefore, the "upper end and the lower end of the tuyere are staggered to form an air vent", and the staggered here means that the upper end and the lower end are no longer at the same time on the original wind tunnel wall trajectory, and at the same time, the upper side of the air vent The relative position relationship between the end and the lower end in the air duct must satisfy the line connecting the upper end and the lower end. The projection point at the lower end is the origin of the plane rectangular coordinate system, starting from the angle of 30° in the positive direction of the X axis. The technical feature of the technical feature is that the right side view of the air conditioner indoor unit of the present invention is a plane, and the upper end and the lower end are connected in the technical feature of the fan-shaped section formed by rotating the counterclockwise direction from 0° to 210°. The projection point of the following edge is the origin, the horizontal axis is the X axis, and the vertical axis is the y axis. In the plane rectangular coordinate system, the starting line at the angle of 30° in the positive direction of the X axis is rotated counterclockwise by 0°. In the sector of the sector formed by 210°, that is, the upper end is located in this sector. The starting line of the angle of 30° in the positive direction of the X-axis means a straight line that is 30° counterclockwise from the X-axis. If the plane rectangular coordinate system is established on the left side view of the air conditioner indoor unit of the present invention, the positional relationship between the upper end and the lower end of the air inlet must satisfy the line of "the upper end and the lower end, and the projection point at the lower end is the origin to be horizontal. The numerical axis is the X-axis, and the vertical axis coordinate system is the y-axis. In the rectangular rectangular coordinate system, the starting line is located at an angle of 30° in the negative direction of the X-axis, and the fan shape is rotated clockwise by 0° to 210°. Within the interval.". The substantive meaning of the two is exactly the same. The starting line of the angle of 30° in the negative direction of the X-axis means a straight line that is 30° clockwise from the X-axis. The right side view of the air conditioner indoor unit of the present invention refers to a projection plane perpendicular to the axial center line of the indoor unit cross flow fan, and the indoor unit air outlet is located on the left side, that is, FIG. 1 of the present invention, and vice versa, the left side view of the air conditioner indoor unit. When the upper end of the air guiding opening and the lower end of the air guiding opening satisfy such a positional relationship in the air outlet duct, a negative pressure region can be formed in the air guiding port, and the object of the present invention is achieved. Otherwise, since the air outlet duct is curved curved toward the axial direction of the cross-flow fan impeller, the heat exchange air flowing out from the cross-flow fan impeller cannot ensure an ideal negative pressure region at the air inlet, which may form an induced wind and At the same time as the wind occurs, even if the heat exchange air flows out through the air inlet and cannot be introduced into the indoor air, the object of the invention is not realized, and the heat exchange air in the air duct of the cross flow fan is split and flowed out, resulting in indoor The air outlet of the machine is insufficient. In the plane rectangular coordinate system established by the plane in the right side view of the air conditioner indoor unit of the present invention, when the upper end and the lower end are connected, the projection point at the lower end is the origin, and the angle of the positive direction of the X axis is 30°. When the wire is rotated counterclockwise in a sector-shaped section formed by 60° to 200°, the negative pressure region formed by the air inlet of the present invention has the best negative pressure effect, and the object of the present invention can be best achieved.

The invention can also provide a damper that can be opened and closed on the air inlet and controlled by the air conditioner remote control, so that the air outlet of the air outlet of the air conditioner is formed by the full heat exchange air and the heat exchange air and the indoor non-heat exchange air. Any conversion between the mixed air and the wind can meet the requirements of the original low-temperature cooling, and meet the need to provide a gentle cool heat exchange wind, giving the user an experience mode.

When the upper end and the lower end of the tuyere of the present invention are staggered to form an air guiding opening, the upper end and the lower end of the tuyere have a plurality of preferred positional structures, which can ideally achieve the object of the present invention, wherein the upper end is curved toward the air duct, and the lower side The staggered arrangement of the original cross-flow fan on the outlet air duct wall is optimal, so that the air intake openings formed are all located in the original cross-flow fan air outlet duct, and do not occupy the space outside the original wind duct wall. It is basically located on the trajectory of the original wind tunnel wall, and has almost no influence on the wind of the wind tunnel. Since the air inlet is arranged in the direction of the air outlet on the original wind tunnel wall, there is no problem of occupying the space outside the wall of the wind duct and being blocked, and the air is smooth, which eliminates the patented component of the D patent. The vents are blocked and do not meet the shortcomings of the ideal wind. When the heat exchange air flowing out of the impeller of the cross flow fan flows through the upper end of the inwardly curved air inlet to the air outlet of the indoor unit, the upper end of the air inlet opening is inwardly curved and the wind is still located in the original cross flow fan The air inlet formed by the lower end of the wall forms a negative pressure zone, and the indoor air outside the wall of the air duct is continuously introduced to mix with the heat exchange air in the air duct of the cross flow fan to form a gentle cool. The heat exchange wind flows out of the indoor unit air outlet. The amount of air at this time should be the indoor air introduced by the heat exchange air of the cross-flow fan impeller and the air inlet, and the total air volume is increased, but the heat exchange energy is still the energy carried by the heat exchange air of the cross-flow fan impeller. The heat exchange energy of the indoor air outlet is unchanged. If it is in the cooling mode, that is to say, the cooling capacity is constant, the air output is increased, and the outlet air 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 outlet becomes soft and comfortable. Thereby eliminating the problem of "air conditioning disease". Since the amount of refrigeration carried by the air having an appropriately increased temperature is not reduced, the amount of airflow is increased, the indoor air circulation is accelerated, the time required to reach the set temperature is reduced, and power saving is achieved, thereby achieving the object of the present invention.

The indoor unit of the split wall-mounted air conditioner is suspended from the wall by a mounting plate on the rear side of the indoor casing and hung on a wall panel mounted on the wall. The wall panel only serves to suspend the indoor unit. It is not a completely sealed whole block. It has many different shapes and different sizes of holes. The surrounding of the wall panel and the rectangular four sides of the back of the indoor unit casing are left. In the gap, a tuyere is opened on the mounting plate on the rear back of the indoor unit casing, and the air inlet of the indoor unit directly communicates with the tuyere. When the indoor unit is suspended from the wall panel by the wall panel, the air inlet of the indoor unit and the air outlet on the rear mounting plate of the indoor unit casing and the air outlet of the air outlet duct wall of the cross-flow fan volute of the present invention are provided. In the same way, the air inlet is connected to the interior. The negative pressure formed by the air inlet can continuously attract the unheated air in the room through the air inlet on the top surface of the indoor unit casing, and mix with the heat exchanged air to flow out of the indoor air outlet. The present invention is to open a tuyere on a mounting plate on the rear side of an indoor unit casing, and to introduce indoor air by using an air inlet of the existing air conditioning indoor unit to achieve the object of the present invention, and is not in the indoor unit casing, that is, Any air outlet is provided on the cover of the D patent, thereby eliminating the D patent's problem of reflow due to the additional air inlet, which not only does not reduce the time and energy consumption required to increase the indoor air to the set temperature. In order not to affect the suspension strength of the mounting plate on the rear side of the indoor unit casing, the air opening formed on the mounting plate is opened in a manner of a small circular opening that is not connected. Since the arrangement results in the vicinity of the existing air-conditioning indoor installation board are slightly different, in the radial direction of the hole, if a barrier is encountered, the passage of the air inlet to the indoor unit can be opened through a set of small circular openings that are not connected.

The volute of the cross-flow fan is a one-shot injection molding part, and an air guiding opening is opened on the outlet air duct wall of the cross-flow fan volute, only one upper end is bent in the air outlet duct, and the lower end is still located in the original cross-flow fan. The rectangular air inlet on the air duct can be formed by one injection molding of the volute of the cross flow fan, so the production cost is not increased. Similarly, the air outlet is formed on the mounting plate on the rear side of the indoor unit casing, and can also be formed in the one-time forming of the rear side of the indoor casing, without increasing the production cost.

The center line of the two long end ends of the rectangular air inlet should be parallel with the axial line of the cross-flow fan impeller, so that the introduced indoor air and the heat exchange air in the cross-flow fan duct are sufficiently uniformly mixed. A plurality of connecting support bars may be arranged between the upper and lower ends of the rectangular air inlet to form a harmonical shape to improve the strength of the rectangular air inlet and reduce the vibration which may occur when the air flows at a high speed. The heat exchange air flowing out from the impeller of the cross flow fan is refracted out of the air duct on the wall of the air outlet duct, and the lower end is still located on the wall of the outlet duct of the original cross flow fan, and between the upper and lower ends of the rectangular air inlet When the vertical distance is controlled within 10 mm, it can ensure that the air inlet is sufficiently convected when the upper end bends less in the air duct without lowering the wind pressure of the air duct. Because the air inlet of the present invention does not occupy the space outside the wall of the wind tunnel, the air conditioning connecting pipe, the air conditioning drain pipe and the power cord which are not wrapped with the heat insulating pipe outside the air outlet duct wall are crowded in a narrow space. Collision and occlusion, the present invention can be provided with an air guiding opening at any position on the full air passage section of the cross-flow fan volute air outlet duct, or a plurality of air guiding openings can be arranged on the full air duct section of the air outlet duct wall. To improve the airflow and the uniformity of the induced air into the air duct, there is no need to define the opening 71 in the rear volute in the D patent. The right position, otherwise it is difficult to avoid the problem of uneven air and insufficient air volume. The invention can further reduce the vertical distance between the upper and lower ends of the rectangular air inlet, and ensure that the air inlet can obtain sufficient air inlet by increasing the number of air intakes, and further, the air inlet air flows to the air outlet. The impact drops to zero. In practice, it is preferable to control the vertical distance between the upper and lower ends of the rectangular air inlet to be within 5 mm.

The air outlet duct of the indoor unit that performs heat exchange by the cross-flow fan is narrow, and it is difficult to accommodate the usual inward air supply device. Even if the normal air supply device is not provided, the air outlet duct is crowded and blocked. It seriously affects the wind. Therefore, the general knowledge of the existing air conditioning technology technicians is difficult to set up the air supply device in the air outlet indoor air duct. For example, the Chinese patent number CN203857578U is named. The first page of the patent specification for "an air conditioner" states that "the existing air conditioners with mounting parts generally use cross-flow fans, cross-flow fans, and the positional relationship between the air duct and the air outlet determines that it is difficult to set it. The extra air supply unit is the same. The invention has a unique air guiding opening in the air outlet duct, which not only can provide additional air supply for the air outlet duct, but also has no influence on the air outlet of the air outlet duct, and overcomes this technical bias.

A rectangular tuyere is opened inward on the cross-flow fan duct, and the relative positional relationship between the shape of the upper and lower long ends of the rectangular tuyere is specially designed, so that the rectangular tuyere does not need to be provided with a separate air guiding component, and The air inlet with the air-inducing function has no air-inducing components, so there is no problem that the air-winding duct is crowded and blocked, which seriously affects the wind, so that the wind is not soft enough, and the air volume is supplied. For the purpose of less invention, the object of the invention is also achieved with almost no increase in production costs. The technical solution proposed in the claims of the D patent is based on the formation of an opening in the rear volute of the air duct of the cross-flow fan, "forming a wind-guiding assembly having an air inlet on the opening" The air guiding port is provided by the air guiding component, which not only has a complicated structure, but also needs to install a setting space, and also brings an increase in production cost.

Due to the adoption of the above technical solutions, the present invention has the following advantages and positive effects:

1. The present invention fully achieves the object of the invention of the D patent and is superior to the technical effect of the purpose of the invention of the D patent.

2. The invention solves the problem that the D-patent has the principle that the air-inducing component is difficult to be ideal and the additional air inlet brings a serious backflow problem.

3. The invention can be implemented on the basis of the existing air-conditioning indoor unit without increasing the cost, and the market competitiveness of the air conditioner is greatly improved.

4. The present invention overcomes the technical bias that the air supply device cannot be installed in the air duct of the cross-flow fan of the indoor unit.
