Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
First embodiment
Referring to fig. 1, the present embodiment provides an indoor unit 100, and in the process that the indoor unit 100 provided in the present embodiment can introduce outdoor fresh air into the room, comfort and user perceptibility can be simultaneously satisfied, and user experience is improved.
The indoor unit 100 is generally installed indoors to exchange heat with indoor air through a heat exchanger provided in the indoor unit 100, and the indoor unit 100 cools the indoor air when the air conditioner operates in a cooling mode, as is common. When the air conditioner operates in the heating mode, the indoor unit 100 heats indoor air. Since the indoor space is always closed when the air conditioner is turned on, the carbon dioxide content of the indoor air is increased due to long-term operation, and the air quality is changed. In order to maintain the indoor air at a comfortable level for a long period of time, it is necessary to introduce a sufficient amount of outdoor air from the outdoor to supplement the oxygen content of the indoor air.
Referring to fig. 1 and fig. 2, in the present embodiment, the indoor unit 100 includes a casing 110, a scroll casing 120 and an air inlet channel (not shown), the air inlet channel is connected to the scroll casing 120 and is configured to introduce outdoor fresh air into the scroll casing 120, the casing 110 has an air inlet surface 112 and a panel surface 111 that are connected to each other, the scroll casing 120 is provided with a fresh air outlet 122, the panel surface 111 is provided with a first air outlet 113, the air inlet surface 112 is provided with an air inlet 114 and a second air outlet 115, the fresh air outlet 122 is communicated with the second air outlet 115 and the first air outlet 113, and the fresh air outside can be introduced into the room through the first air outlet 113 and the fresh air outside blown out from the second air outlet 115 enters the casing 110 through the air inlet 114.
In this embodiment, the volute 120 and the air inlet channel form a fresh air module, which is mainly used for introducing outdoor fresh air, when the indoor unit 100 is installed indoors, the surface opposite to the panel surface 111 is fixed on a wall, the panel surface 111 is a display surface, that is, the surface can be visually seen by a user, the panel surface 111 is provided with the first air outlet 113, and the user can visually perceive that the outdoor fresh air is introduced into the room. If only the first air outlet 113 is disposed on the panel 111, the outdoor fresh air entering the room from the first air outlet 113 will have a certain temperature difference with the indoor air, resulting in poor indoor comfort.
For example: the refrigeration mode can be opened when outdoor temperature is higher to the general case, and the temperature of current room air can be lower than the temperature of outdoor new trend, lets in the indoor back with outdoor new trend is direct from panel 111, can lead to whole room air's temperature to rise when having solved the oxygen content, leads to indoor comfort relatively poor.
Similarly, the heating mode can be started under the condition of lower outdoor temperature in general, the temperature of the current indoor air is higher than that of the outdoor fresh air, the outdoor fresh air is directly introduced into the room from the panel surface 111, the temperature of the whole indoor air is reduced while the oxygen content is reduced, and the indoor comfort level is poor.
The air intake surface 112 is generally disposed at the top of the housing 110, and the air intake opening 114 disposed on the air intake surface 112 is mainly used for introducing indoor air into the housing 110 for heat exchange. The second air outlet 115 is formed in the air inlet surface 112, when outdoor fresh air enters the room from the second air outlet 115, the fresh air enters the shell 110 again under the action of an indoor fan installed at the air inlet 114, and enters the room again after heat exchange of the indoor unit 100, and the comfort level of the room can be improved due to the mode, but because the second air outlet 115 is formed in the air inlet surface 112, a user cannot perceive whether the outdoor fresh air enters the room.
In this embodiment, set up first air outlet 113 simultaneously on panel 111, set up second air outlet 115 on air inlet 112, after outdoor new trend enters into spiral case 120 from the new trend passageway, the part enters into indoorly through first air outlet 113, the part enters into indoor back through second air outlet 115 and carries out the heat transfer in entering into indoor set 100 from air intake 114, finally enter into indoorly again, avoid more outdoor new trend to directly enter into indoorly, guarantee indoor temperature's stability, set up first air outlet 113 on panel 111 simultaneously, set up second air outlet 115 on air inlet 112, can compromise user perception when guaranteeing indoor comfort level, improve user's experience and feel.
In the present embodiment, the fresh air outlet 122 is disposed at a position of the volute 120 corresponding to a connection of the air inlet surface 112 and the panel surface 111.
In this embodiment, the number of the fresh air outlets 122 is one, and in order to ensure that one fresh air outlet 122 can simultaneously take into account the first air outlet 113 and the second air outlet 115, the fresh air outlet 122 is disposed at a position of the volute 120 corresponding to a connection position of the air inlet surface 112 and the panel surface 111. The fresh air outlet 122 can be connected with the first air outlet 113 and the second air outlet 115 by the aid of the air inlet and the air outlet.
Generally, the panel surface 111 and the air inlet surface 112 are disposed at an included angle, the connection between the panel surface 111 and the air inlet surface 112 has a corner, the fresh air outlet 122 is disposed at a position of the scroll casing 120 corresponding to the corner, so that the fresh air outlet 122 corresponds to the panel surface 111, and the fresh air outlet 122 corresponds to the air inlet surface 112.
It should be noted that, in other embodiments of the present invention, there may be two fresh air outlets 122, two fresh air outlets 122 are disposed on the scroll casing 120, one of the fresh air outlets 122 is communicated with the first air outlet 113, and the other of the fresh air outlets 122 is communicated with the second air outlet 115, after the outdoor fresh air enters the scroll casing 120 through the air inlet channel, the indoor fresh air is introduced into the room through the communicated fresh air outlet 122 and the first air outlet 113, and meanwhile, the indoor fresh air can enter the air inlet 114 through the second air outlet 115 and the other of the fresh air outlets 122, and then exchanges heat from the inside of the indoor unit 100 at the air inlet 114, and enters the room again after exchanging heat.
In addition, the number of the fresh air outlets 122 may be three, four, or other numbers, and the number of the fresh air outlets 122 is not particularly limited.
In this embodiment, the fresh air outlet 122 has a first section 124 and a second section 126 that are communicated with each other, the first section 124 is disposed toward the panel surface 111 and is communicated with the first air outlet 113, and the second section 126 is disposed toward the air inlet surface 112 and is communicated with the second air outlet 115.
The first section 124 and the second section 126 are communicated with each other, and outdoor fresh air blown out from the first section 124 is blown out toward the panel surface 111 and blown into the room through the first air outlet 113. Similarly, the outdoor fresh air blown out from the second stage 126 is blown out toward the fresh air surface, and blown into the room through the second outlet port 115.
In this embodiment, the first segment 124 may be directly disposed corresponding to the first outlet 113, that is, a projection of the first segment 124 on the panel surface 111 coincides with the first outlet 113, and outdoor fresh air blown out from the first segment 124 is directly blown out from the first outlet 113.
In addition, in other embodiments of the present invention, the first segment 124 may be communicated with the first air outlet 113 through the air guiding channel. The fresh air in the volute 120 is blown out from the first section 124, enters the air guide channel, is guided by the air guide channel, and is blown out from the first air outlet 113.
Similarly, the second segment 126 is directly disposed corresponding to the second air outlet 115, and it can also be understood that a projection of the second segment 126 on the fresh air surface coincides with the second air outlet 115, and the outdoor fresh air blown out from the second segment 126 can be directly blown out through the second air outlet 115.
Similarly, in other embodiments of the present invention, the second segment 126 can be communicated with the second air outlet 115 through an air guiding channel. The fresh air in the volute 120 is blown out from the second section 126, enters the air guide channel, is guided by the air guide channel, and is blown out from the second air outlet 115.
In this embodiment, the second section 126 is disposed obliquely toward the first section 124. The end of the second section 126 close to the first section 124 is lower than the end of the second section 126 far from the first section 124, which can be considered that the end of the second section 126 far from the first section 124 is closer to the air intake surface 112, the second section 126 slightly inclines towards the panel surface 111, when outdoor intake air is blown out through the fresh air outlet 122, the second section 126 and the first section 124 which are obliquely arranged can be in smooth transition, so that outdoor fresh air in the scroll casing 120 can be blown into the room from the first air outlet 113 or the second air outlet 115 as much as possible, and the utilization rate of the outdoor fresh air is improved.
Meanwhile, the indoor unit 100 is generally installed near the roof, and the second section 126 is disposed toward the first section 124, so that the fresh outdoor air blown out obliquely from the second air outlet 115 is reflected by the roof and then blown out obliquely downward, and the fresh air brought by the fresh outdoor air can be sensed more quickly. And outdoor fresh air obliquely blown out from the second air outlet 115 in the vertical direction and outdoor fresh air blown out from the first air outlet 113 in the horizontal direction form multi-dimensional air supply, so that the flow of the outdoor fresh air indoors is accelerated, and the indoor fresh air exchange efficiency is improved.
In this embodiment, the first air outlet 113 is disposed near the air inlet surface 112, and the second air outlet 115 is disposed near the panel surface 111.
Because the fresh air outlet 122 is disposed at the connection position of the panel surface 111 and the air inlet surface 112, in order to enable the first air outlet 113 and the second air outlet 115 to be disposed at the connection position of the panel surface 111 and the air inlet surface 112, the first air outlet 113 and the second air outlet 115 are disposed near the connection position of the panel surface 111 and the air inlet surface 112.
In the present embodiment, the projected area of the second segment 126 on the fresh air surface is larger than the projected area of the first segment 124 on the panel surface 111. Under the same wind speed, the air output of the outdoor fresh air output from the second section 126 is greater than that of the outdoor fresh air output from the first section 124.
Because the first section 124 is connected with the first air outlet 113, outdoor fresh air blown out from the first air outlet 113 directly enters the room, and if more outdoor fresh air is blown out from the first air outlet 113, the indoor temperature can be reduced quickly, and the indoor comfort level is deteriorated. The first air outlet 113 arranged on the panel 111 mainly aims to let the user perceive that outdoor fresh air enters the room, and therefore it is only necessary to ensure that the first air outlet 113 has outdoor fresh air to blow out, and the air output of the first air outlet 113 does not need to be too large.
Similarly, the second section 126 is connected to the second air outlet 115, outdoor fresh air blown out from the second air outlet 115 enters the indoor unit 100 through the air inlet 114, and the temperature of the outdoor fresh air is increased after heat exchange in the indoor unit 100, and after entering the indoor unit again, the indoor temperature is not reduced, and the experience of the user is improved.
Therefore, in this embodiment, in order to ensure that the user perceives that outdoor fresh air enters the room and the indoor temperature needs to be relatively stable, the projection area of the second section 126 on the fresh air surface is larger than the projection area of the first section 124 on the panel surface 111, so as to ensure that the air output amount of the outdoor fresh air output from the second air outlet 115 is larger than the air output amount of the outdoor fresh air output from the first air outlet 113.
The projected area of the second section 126 on the fresh air surface is typically set to be 1.5 to 2.5 times the projected area of the first section 124 on the panel surface 111. The outdoor fresh air as much as possible is blown out from the second air outlet 115, enters the indoor unit 100 through the air inlet 114 for heat exchange, and then enters the indoor unit again, so that the indoor temperature is ensured not to be reduced as much as possible.
Preferably, in the present embodiment, the ratio of the projected area of the second segment 126 on the fresh air plane to the projected area of the first segment 124 on the panel plane 111 is 2: 1. The stability of indoor temperature can be guaranteed under the condition that outdoor fresh air enters the room to let the user perception.
In this embodiment, the air outlet direction of the second section 126 and the air outlet direction of the first section 124 form an included angle. The first air outlet 113 is disposed on the panel surface 111, and an air outlet direction of the first section 124 is perpendicular to the panel surface 111. Outdoor fresh air blown out from the first section 124 can be blown out from the first air outlet 113 completely, and the utilization rate of the outdoor fresh air is improved.
Similarly, because the second section 126 is disposed on the air inlet surface 112, and the air outlet direction of the second section 126 is perpendicular to the air inlet surface 112, outdoor fresh air blown out from the second section 126 can be completely blown out from the second air outlet 115, thereby improving the utilization rate of the outdoor fresh air.
Referring to fig. 3 and 4, in the present embodiment, the indoor unit 100 further includes a panel 150, the first air outlet 113 is multiple, and the multiple first air outlets are disposed on the panel 150.
In the present embodiment, the plurality of first outlets 113 are arranged on the panel 150 in a matrix. The plurality of first outlets 113 are arranged on the panel 150 in a matrix manner, so that the aesthetic appearance of the whole panel 150 can be improved.
In addition, in other embodiments of the present invention, the plurality of first outlets 113 may be arranged on the panel 150 in other shapes, for example, in a diamond shape, a trapezoid shape, or a circular shape, etc. on the panel 150.
Meanwhile, the aperture of the first air outlet 113 is small, when outdoor fresh air is blown out from the first air outlet 113, countless first air outlets 113 can divide the outdoor fresh air into countless small strands, when the outdoor fresh air is blown to a user, breeze blown out can be sensed, and the experience of the user is improved. Simultaneously, be microporous structure with first air outlet 113 setting, can avoid inside great impurity enters into casing 110 from first air outlet 113, influence the work of the inside other spare parts of casing 110.
It is easy to understand that, the aperture of the first air outlet 113 is small, the volume of the impurities which can be prevented is smaller, and the volume of the impurities which is larger than the aperture of the first air outlet 113 cannot enter the inside of the housing 110, so that the dustproof effect is improved.
In this embodiment, the shape of the first air outlet 113 may be a circle, a rectangle, or a diamond, and the shape of the first air outlet 113 is not particularly limited. It should be noted that, in other embodiments of the present invention, there may be one first air outlet 113, and when there is one first air outlet 113, the aperture of the first air outlet 113 is generally larger, and at this time, a first air outlet plate may be disposed at the first air outlet 113, and a plurality of through holes are disposed at intervals on the first air outlet plate, and the through holes are communicated with the fresh air outlet 122.
First air-out board sets up in first air outlet 113 department, can play the effect of sheltering from to first air outlet 113, can avoid great impurity to enter into casing 110 inside from first air outlet 113, influences the work of the inside other spare parts of casing 110.
In this embodiment, the number of the through holes is not specifically limited, the aperture of the through holes is small, when outdoor fresh air is blown out from the first air outlet 113, countless through holes can divide the outdoor fresh air into countless small strands, when the outdoor fresh air is blown to a user, the user can feel that the fresh air is blown out, and the experience of the user is improved.
Referring to fig. 5, in the present embodiment, the indoor unit 100 further includes a plurality of second air-out plates 140, the plurality of second air-out plates 140 are disposed at the first air outlet 113 at intervals, and a gap between two adjacent second air-out plates 140 is communicated with the fresh air outlet 122.
In this embodiment, since the second air outlet 115 is disposed on the air inlet surface 112, generally, the air inlet surface 112 and the top surface of the casing 110 can be quickly diffused to other indoor locations when the outdoor fresh air is blown out from the second air outlet 115. The second air outlet plate 140 is arranged at the second air outlet 115, so that outdoor fresh air can be guided, and the fresh air blown out from the second air outlet 115 is blown out along the direction of the second air outlet plate 140.
Preferably, the second air outlet plate 140 is disposed toward the air inlet 114, so that outdoor fresh air blown out from the second air outlet 115 can be diffused to the air inlet 114, and then enters the indoor unit 100 from the air inlet 114 for heat exchange treatment, thereby preventing more outdoor fresh air from being directly diffused indoors, resulting in unstable indoor temperature, and reducing indoor comfort.
