Description
Technical field
The invention belongs to air-conditioning technique field, only relate to a kind of indoor apparatus of air conditioner.
Background technology
Operationally, room air is inhaled into indoor set to existing indoor apparatus of air conditioner under the effect of tangential impeller, becomes heat exchange air, blown out by indoor set exhaust air flue with after heat exchanger heat exchange.Existing indoor apparatus of air conditioner exhaust air flue be one close air channel, heat exchange air before being blown with exhaust air flue outside room air be isolated, therefore, exhaust air flue blowout whole be heat exchange wind.Particularly in cooling mode, the indoor apparatus of air conditioner inlet and outlet temperature difference reaches about 14 degree, relatively indoor original air themperature, form the larger temperature difference, after air conditioning reaches design temperature, air-conditioning is in and is interrupted open and close to regulate and control the duty of room temperature around design temperature, the leaving air temp of indoor set is lower, human body stands directly blowing of this indoor set air-out, will feel terribly cold, often be subject to directly blowing of the indoor set air-out of this excessive temperature differentials, will obtain usually said " air conditioner disease ", this problem is the old,weak,sick and disabled, with it children user, when people sleep use, especially outstanding.In order to address this problem, mixed ventilation device must be set, improve the temperature difference of indoor set air-out and room air.But the air-out of the tangential impeller in indoor set forms the characteristic of air-out by refraction on exhaust air flue wall, and the exhaust air flue determining tangential impeller requires to design narrow as far as possible, and is towards tangential impeller axial line arc-shaped bend.Indoor machine cost-saving and attractive in appearance on also need Miniaturization Design, common air-supply arrangement cannot be held in the exhaust air flue of therefore indoor set, otherwise, air-supply arrangement is set by force, the air-out of exhaust air flue can be blocked, air-supply arrangement also can change the air-out refractive direction of tangential impeller, has a strong impact on air-out blast and air output.For a long time, the technical staff in air-conditioning technique field think always adopt tangential impeller to carry out heat exchange indoor set exhaust air flue in cannot air-supply arrangement be set.As China Patent No. CN201420218504, just clearly state in the patent specification first page of by name " a kind of air-conditioner " " the existing air-conditioning with installation portion generally all adopts axial-flow fan; axial-flow fan, air channel and determine with the position relationship of air outlet be difficult to arrange extra air-supply arrangement within it ".China Patent No. CN201420218683 is called " a kind of indoor apparatus of air conditioner with air-supply arrangement ", and patent specification first page also clearly states " the existing air-conditioning with installation portion generally all adopts axial-flow fan; and axial-flow fan is parallel with outlet and arrange with its axis; therefore; the wind pushing performance met the demands be obtained; the volume of this air-conditioning is all comparatively large, and extra air-supply arrangement can not be set interior.", the air-conditioning of installation portion herein, refer to the wall-hanging air conditioner indoor unit be arranged on wall and the ceiling type air conditioner indoor set be hung on indoor top, axial-flow fan is herein tangential impeller.Therefore, the technical staff of field of air conditioning, always by air-supply arrangement design near outside the air outlet of indoor set, and be provided with upper and lower wind-guiding, left and right wind-guiding, the air ducting of a multitude of names such as shunting wind-guiding for this reason, patented technology document about the air ducting outside air outlet of indoor set is also thousands of, object, with regard to one, improves space temperature variation, reduces the impact that cold wind directly blows.China Patent No. 2014207299611, on the rear spiral case of the supply air duct at tangential impeller that the patent (being called for short D patent) being called " a kind of Split wall-mounted type air conditioner " proposes, namely supply air duct wall arranges air-supply arrangement, import the indoor air without heat exchange and with the heat exchange air in supply air duct is formed mix wind after deliver to the technical scheme of indoor.The supply air duct of indoor apparatus of air conditioner tangential impeller is indoor set exhaust air flue.This technical scheme main point installs in the upper shed of supply air duct wall and at opening part to arrange air inducing assembly, additional air inlet is formed in the relevant position of affiliated indoor set case, air inducing assembly is as D patent specification 0008, it is such that 0009 paragragh illustrates: air inducing assembly is multiple air inducing grids, " air inducing grid comprise be positioned on described rear spiral case inlet pressure first and deviate from bending second in described supply air duct direction ", obviously, the air inducing assembly of D patent is also the outside being arranged on exhaust air flue wall.The goal of the invention of D patent has 2 points: 1, is formed and less the mixing wind and deliver to indoor of the indoor temperature difference at supply air duct, with it the less mixing wind of the temperature difference to human body, feels cool and not cold, comparatively soft comfortable, improves the comfortableness experience of user; 2, increase the air output of air outlet of indoor set, contribute to accelerating the flowing velocity of room air and uniformity, reduce room air and reach time needed for design temperature and energy consumption.But there is shortcoming in the technical scheme of D patent: the space formed with indoor set casing outside indoor apparatus of air conditioner exhaust air flue wall to be uniquely used for arranging the air conditioner connecting pipe and water drainage pipe of air conditioner and the place with off-premises station connecting power line that thick thick insulating tube is wrapped in, these pipes and line almost tie up the space outside the wind wind path wall that overfills and are close to outside indoor set exhaust air flue wall, existing indoor apparatus of air conditioner is no matter from attractive in appearance or from cost-saving upper, all be tending towards super-thin smallization design, after super-thin smallization design, this space is except meeting above-mentioned pipeline and line arrangement, unnecessary space air inducing assembly has not been had outside indoor set exhaust air flue wall, therefore, even if arrange air inducing assembly by force, the air-vent of air inducing assembly also can by the air conditioner connecting pipe wrapped up through insulating tube, water drainage pipe of air conditioner and power line withstand and to block and air inducing is not smooth, absorbing quantity is not enough, the air inducing grid that even there will be in air inducing assembly is withstood closed air-vent and cannot the situation of air inducing, reaching D patented invention object technique effect also will be poor, D patent specification the 3rd page of the 0026th paragragh emphasizes that opening 71 must be limited to the particular segment correct position of rear spiral case 7 and the restriction to opening two ends distance, illustrate that the technical scheme of D patent exists this problem with regard to implicit, in fact, what kind of angle no matter D patent " air inducing grid ... deviate from second that described supply air duct direction is bending " make is arranged, as long as be positioned at outside former exhaust air flue molded line, just there will be tangential impeller flow through come air-out in a part be refracted into outside exhaust air flue wall, air inducing assembly does not become complete negative pressure, effect of not only not quoting forms air-out on the contrary, the goal of the invention of D patent can not be reached.
Summary of the invention
1, object of the present invention is just to provide a kind of air-conditioning and blends wind indoor set, reaching, the existing indoor apparatus of air conditioner air-out of solution is soft not, and namely the problem that air-supply air quantity is few reaches D patented invention object simultaneously completely, solves the problem of the air inducing assembly blower effect difference that D patent exists.
Goal of the invention of the present invention realizes in the following manner: a kind of air-conditioning blends wind indoor set, comprise indoor set casing, tangential impeller exhaust air flue, tangential impeller exhaust air flue wall, it is characterized in that: tangential impeller exhaust air flue wall offers air-vent, air-vent is perpendicular to indoor set tangential impeller axial line, air outlet of indoor set is arranged in the projection line of the projection plane of lower left side, the point crossing with exhaust air flue wall is that the clockwise angle of the exhaust air flue wall tangent line positive direction section of incision superius is more than or equal to 10 ° to being less than or equal to 200 °, indoor set housing side wall offers air port, indoor set housing side wall air port is provided with air inducing fan.
Goal of the invention of the present invention can also be realized by such mode: a kind of air-conditioning blends wind indoor set, comprise indoor set casing, tangential impeller exhaust air flue, tangential impeller exhaust air flue side plate, it is characterized in that: on indoor set housing side wall and tangential impeller exhaust air flue side plate, offer air port, the air port that the air port that indoor set housing side wall is offered or tangential impeller exhaust air flue side plate are offered is provided with air inducing fan.
The air inducing fan that air port of the present invention is arranged is aerofoil fan or centrifugal fan.
Indoor apparatus of air conditioner of the present invention is the indoor set specially referring to adopt tangential impeller air inlet/outlet, so the tangential impeller exhaust air flue in the present invention is indoor set exhaust air flue, it is rectangular air channel that usual tangential impeller exhaust air flue forms cross section by the snail tongue of exhaust air flue part and spiral case and biside plate, during with snail tongue and spiral case for arranging front and back, biside plate is divided into two pieces, left and right, snail tongue is connected with spiral case that to enclose cross section be behind rectangular air channel by left and right sides plate, the snail tongue of tangential impeller and spiral case are just tangential impeller exhaust air flue wall, all the other both sides are then tangential impeller exhaust air flue side plate, the indoor set adopting tangential impeller air inlet/outlet is rectangle, be generally air intake above indoor set casing, below air-out, the casing left and right sides is indoor set housing side wall, air-vent of the present invention is arranged on the spiral case of tangential impeller exhaust air flue wall, after the exhaust air flue wall of namely usually alleged tangential impeller on spiral case, therefore, tangential impeller exhaust air flue wall of the present invention offers on spiral case that air-vent is tangential impeller exhaust air flue wall and offer air-vent, tangential impeller exhaust air flue wall of the present invention is offered in the technical scheme of air-vent, the air port that indoor set housing side wall is wherein offered is positioned on indoor set housing side wall corresponding outside tangential impeller exhaust air flue wall, tangential impeller exhaust air flue side plate of the present invention offer in the technical scheme in air port, the air port that indoor set housing side wall is offered is positioned on the corresponding indoor set housing side wall of exhaust air flue.Usual tangential impeller is oval tubular, the exhaust air flue cross section of tangential impeller is rectangle, the cross section of the air outlet of indoor set is rectangle, the axial line of tangential impeller and above-mentioned rectangular long centerline parallel, so the air-vent that tangential impeller exhaust air flue wall is offered also should be long center line rectangle parallel with it relatively.Refer to accompanying drawing 3, form rectangular air-vent perpendicular to indoor set tangential impeller axial line, air outlet of indoor set is arranged in the projection line of the projection plane of lower left side, with tangential impeller exhaust air flue air-out direction 161 for direction, along exhaust air flue 16 molded line, first crossing with exhaust air flue 16 molded line point is the incision superius A intersected with exhaust air flue wall, and another corresponding point of contact is then the incision inferius B crossing with exhaust air flue wall.In addition, the air-vent that tangential impeller exhaust air flue wall is offered also can be circle, oval, other shapes such as square, as long as meet these air-vents perpendicular to indoor set tangential impeller axial line, air outlet of indoor set is arranged in the projection line of the projection plane of lower left side, and the point crossing with exhaust air flue wall is that the clockwise angle of the exhaust air flue wall tangent line positive direction section of incision superius is more than or equal to 10 ° to being less than or equal to 200 °.
The present invention is perpendicular to indoor set tangential impeller axial line, and the projection plane that air outlet of indoor set is positioned at lower left side is indoor apparatus of air conditioner right view, namely accompanying drawing 1 of the present invention, otherwise, be then indoor apparatus of air conditioner left view.Air outlet of indoor set is positioned at lower left side and tangential impeller air-out direction is lower left side.
The characteristic of indoor set tangential impeller refraction air-out determines exhaust air flue and is different from general blower fan exhaust air flue, general blower fan exhaust air flue technology is not also suitable for the design of tangential impeller exhaust air flue, the molded line of the exhaust air flue of tangential impeller is for facing toward tangential impeller direction of axis line arc-shaped bend, as being only simply open an air-vent on original exhaust air flue wall, the incision superius of air-vent and incision inferius are still positioned on the exhaust air flue wall of arc-shaped bend, the air that tangential impeller flows out will directly flow out facing to air-vent forms malleation at air-vent, the object introducing room air can not be reached.So the relative position structural relation of the projection line that the incision superius of air-vent and incision inferius must be formed on exhaust air flue wall meets the air-vent that " air-vent is perpendicular to indoor set tangential impeller axial line; air outlet of indoor set is arranged in the projection line of the projection plane of lower left side, and the point crossing with exhaust air flue wall is that the clockwise angle of the exhaust air flue wall tangent line positive direction section of incision superius is more than or equal to 10 ° to being less than or equal to 200 ° " this technical characteristic could form complete negative pressure.Refer to accompanying drawing 3, the line of incision superius A to incision inferius B is the projection line that incision superius and incision inferius form, the point that exhaust air flue wall intersects is that the exhaust air flue wall tangent line of incision superius refers to incision superius A as point of contact, with the tangent line that exhaust air flue wall 16 molded line at incision superius place is point of contact at incision superius A, i.e. 130 in accompanying drawing 3, in accompanying drawing 3 161 is tangential impeller air-out direction, tangent line 130 direction of arrow is namely expressed as tangent line and tangential impeller air-out direction 161 is equidirectional, cross tangent line incision superius A and the equidirectional line segment of tangential impeller air-out direction 161 is tangent line positive direction section, otherwise, it is then tangent line negative direction section.Clockwise angle refers to the line of incision superius A to incision inferius B with incision superius A for initial point, clockwise forwards the angle with this tangent line positive direction section to, and namely in accompanying drawing 3 131, the direction of arrow in 131 is marked as clockwise.If in indoor apparatus of air conditioner left view, clockwise angle is then counterclockwise angle, and both character is identical.When the molded line occurring exhaust air flue wall is the special case of straight line, the straight line that exhaust air flue wall-shaped line is formed is the exhaust air flue wall tangent line at incision superius A place.When the incision superius of air-vent meets such positional structure relation to the incision inferius of air-vent on exhaust air flue wall, air-vent could form negative pressure region, the room air outside air-vent formed after will being introduced by the air port that indoor set housing side wall is offered and mixing with the heat exchange wind in tangential impeller exhaust air flue soft mixing distinguished and admirable go out air outlet of indoor set realize goal of the invention of the present invention.Otherwise, because exhaust air flue is towards tangential impeller direction of axis line arc-shaped bend, the heat exchange air that tangential impeller refraction is flowed out just can not ensure to form negative pressure region completely at air-vent, likely form the situation that air inducing and air-out occur simultaneously, even form heat exchange air flowed out by air-vent and the situation of room air can not be introduced, goal of the invention not only cannot realize, and the heat exchange wind in tangential impeller exhaust air flue also can be made to be shunted outflow, causes indoor set air-out volume not enough.
When the spiral case of tangential impeller exhaust air flue wall of the present invention offers air-vent, the incision superius of air-vent and incision inferius have multiple relative position structure to reach the object of the invention, wherein bending in exhaust air flue with incision superius, incision inferius is still positioned at and staggering on former tangential impeller exhaust air flue wall-shaped line is set to the best, the air-vent of such formation is just all positioned at former tangential impeller exhaust air flue wall, do not tie up the space outside former exhaust air flue wall at all, be located substantially on again on former exhaust air flue wall-shaped line, the air-out of exhaust air flue is not almost affected.Former tangential impeller exhaust air flue wall of the present invention is the exhaust air flue wall of the tangential impeller supposed when not opening air-vent.Because air-vent does not exist the problem tying up space outside exhaust air flue wall and be blocked, air inducing is smooth, and absorbing quantity is sufficient, and the air port also just eliminating the air inducing assembly of D patent is withstood blocks and the shortcoming of blower effect difference.Just because of air-vent of the present invention does not take the space outside exhaust air flue wall at all, can not with exhaust air flue wall outside pipe, the conflict that circuit ties up and being withstood is blocked, the present invention any position in the full wall section of the exhaust air flue wall of tangential impeller spiral case can arrange air-vent, 3 to 8 even more air-vents also can be set in exhaust air flue wall full wall section and enter uniformity in exhaust air flue to improve absorbing quantity and air inducing, there is not the specific correct position that must be limited to rear spiral case in D patent to opening 71, otherwise be just difficult to the problem avoiding occurring uneven air-out and absorbing quantity deficiency.When the heat exchange wind that tangential impeller flows out flows to air outlet of indoor set through aduncate air-vent incision superius, the aduncate incision superius of air-vent and the air-vent of incision inferius composition be still positioned on former tangential impeller exhaust air flue wall form negative pressure region, room air will be introduced into by the air port that indoor set housing side wall is offered in air-vent mix with the heat exchange wind in tangential impeller exhaust air flue formed afterwards soft mixing distinguished and admirable go out air outlet of indoor set.The heat exchange air-out that air output now should be tangential impeller adds the room air that air-vent is introduced, total air output strengthens, but heat-exchange power is constant, energy entrained by the heat exchange air-out still flowed out for tangential impeller, air outlet of indoor set heat outputting positive energy exchange is constant, as being the words under refrigeration mode, in other words, refrigerating capacity is constant, air output increases, and leaving air temp is just suitably improved, and makes the air-out of air outlet of indoor set become cool breeze from human body sensory cold wind, air-out becomes soft comfortable, thus eliminates the problem of " air conditioner disease ".Because the refrigerating capacity entrained by air-out that temperature obtains suitably improving does not reduce, air output obtains increase, and indoor air circulation accelerates, and reaches the time decreased needed for design temperature, power and energy saving, thus reaches objects of the present invention.
Above-mentioned room air by the air port that indoor set housing side wall is offered be introduced in air-vent mix with the heat exchange wind in tangential impeller exhaust air flue after formed soft mixing distinguished and admirable go out air outlet of indoor set time, because the energy of the heat exchange wind of tangential impeller outflow is certain, after forming mixing wind, total air output adds, so air-out wind speed is just inevitable grand to some extent low, air-out range also reduces to some extent, now, air port on indoor set housing side wall is arranged air inducing fan, one is improve air inducing air quantity, the temperature of the mixing wind formed is made to obtain larger raising, two is that the room air self introduced is provided with certain wind energy, solve air-out wind speed grand to some extent low, the problem that air-out range reduces to some extent, when air inducing rotation speed of the fan makes the flow velocity introducing wind reach and be greater than the flow velocity of heat exchange wind in exhaust air flue, it is suitable that indoor set obtains the heat exchange air-out that the air-out wind speed of air output that increases and air-out range will be simple with former indoor set.When the air port on indoor set housing side wall being arranged air inducing fan, also air guide duct can be set on air inducing fan, air guide duct extends and covers the air-vent that tangential impeller exhaust air flue wall is offered, air guide duct offers air port facing to the side of air-vent, make air inducing wind energy, air inducing air quantity does not almost have the directed air-vent that imports damply to enter indoor set exhaust air flue, and blower effect is better.Usual indoor apparatus of air conditioner casing both sides have the pipe hole walking pipe for mounting arrangements tube connector, only need to use one of them pipe hole after installation, the air port that another pipe hole then can be used as on indoor set housing side wall uses and arranges air inducing fan above.
When offering air port on indoor set housing side wall and tangential impeller exhaust air flue side plate, when indoor set housing side wall or tangential impeller exhaust air flue side plate on the air port offered arrange air inducing fan, now just without the need to offering air-vent on tangential impeller exhaust air flue wall, room air directly by the air inducing fan on these air ports be introduced in tangential impeller exhaust air flue mix with heat exchange wind after formed soft mixing distinguished and admirable go out air outlet of indoor set, the mixing wind air quantity formed is at air-out wind speed equally, air-out range obtains enough large increase when substantially constant, thus reach the object of required mixing wind.When indoor set housing side wall or tangential impeller exhaust air flue side plate on the air port offered arrange air inducing fan, so that the air port on tangential impeller exhaust air flue side plate to arrange the blower effect of air inducing fan for optimum.
During the invention process can about two, the left and right of indoor set casing side plate and tangential impeller exhaust air flue on two side plates simultaneously or side offer air port separately, accordingly, may also be on the air port offered at two, left and right side plate or side side plate and air inducing fan be set.
The exhaust air flue that tangential impeller carries out the indoor set of heat exchange is narrower, be difficult to hold under comprise the common inside air-supply arrangement of air inducing assembly in D patent, even if exempt to be provided with by force common air-supply arrangement, exhaust air flue also can be tied up blocking, change the direction of tangential impeller refraction air-out, have a strong impact on air-out, therefore, the technical staff in existing air-conditioning technique field, being generally familiar with as introducing in description background technology of the present invention indoor apparatus of air conditioner exhaust air flue can not arrange extra air-supply arrangement interior.Instant invention overcomes this technology prejudice, in exhaust air flue, be provided with the air-vent of ad hoc structure, not only additionally can blow for exhaust air flue, add air output, not tie up air channel again, harmful effect can not be produced to the air-out of exhaust air flue.
Tangential impeller exhaust air flue wall inwardly offers air-vent, and specific design has been done to the relative position structural relation at two point of contacts up and down of air-vent, air-vent self is made just to have become to be provided with the air-vent of air inducing function, also just without the need to separately arranging air inducing assembly again.Without air inducing assembly, just there is not exhaust air flue and tied up blocking, have a strong impact on the problem of air-out, thus reach that namely to realize solving air-out soft not yet, the goal of the invention that air-supply air quantity is few, also reaches when production cost does not increase and implements object of the present invention.And the technical solution proposed in claims of D patent, form opening on the rear spiral case of the supply air duct of axial-flow fan, " form the air inducing assembly with air-vent over said opening ", air-vent is provided by air inducing assembly, not only complex structure, need installation space is installed, also bring the increase of production cost.
Owing to have employed technique scheme, tool of the present invention has the following advantages and good effect:
1, the present invention has formation and less the mixing wind and deliver to the indoor advantage with increasing indoor set air output of the indoor temperature difference in indoor apparatus of air conditioner exhaust air flue, reaches the goal of the invention of D patent completely and is better than D patented invention object technique effect comprehensively.
2, the invention solves the problem that the air inducing assembly blower effect of D patent existence is poor.
3, the technology prejudice of air-supply arrangement can not be set in the tangential impeller exhaust air flue that instant invention overcomes indoor apparatus of air conditioner.
4, the mixing air-out of indoor set of the present invention, compared with original indoor set air-out, air-out wind speed, air-out range is substantially constant, but air-out volume enlarges markedly.
