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 the technical scheme of D patent has three shortcomings: 1, 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, the Article 1 goal of the invention technique effect reaching D patent 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, the air-outlet part flow through with regard to there will be tangential impeller is refracted into outside exhaust air flue wall, air inducing assembly does not become negative pressure, effect of not only not quoting forms air-out on the contrary, the Article 1 invention order of D patent can not be reached.2, said to the 3rd page of the first row as D patent specification second page last column, additional air inlet distance air outlet is far away, the air-out of air outlet of indoor set just can be avoided through the problem of additional air inlet backflow, the thickness of current indoor apparatus of air conditioner, namely general thick by 300mm in one's early years perpendicular to the length on wall direction, thin type is designed into present 135mm-200mm, indoor set case arranges additional air inlet to be designed distance air outlet is far away again, also the thickness of indoor set can not be exceeded, one goes out one enters two air ports, only at a distance of 135mm-200mm, particularly the air inlet/outlet angle of inlet and outlet is less than 90 °, reflux problem cannot be avoided and more serious certainly.This recirculation zone of air-conditioning is positioned at edge under indoor set, usually away from the zone of action of people in indoor, the air quantity that backflow makes air outlet of indoor set blow to the zone of action usually needing air conditioning reduces, air output is to the minimizing in object region, D patent not only can not be reduced add on the contrary room air to reach time needed for design temperature and energy consumption, be also just difficult to reach the 2nd article of goal of the invention technique effect of D patent.3, present air-conditioning market competition, air-conditioning profit is increasingly meagre, and D art solutions will reach goal of the invention by increase air inducing assembly and additional air inlet, these all can increase cost, certainly will reduce product competitiveness because of the increase of production cost.
Summary of the invention
1, object of the present invention is just to provide a kind of indoor apparatus of air conditioner, reaching, the existing indoor apparatus of air conditioner air-out of solution is soft not, namely the problem that air-supply air quantity is few reaches D patented invention object simultaneously completely, and the air inducing assembly blower effect difference and the additional air inlet that solve the existence of D patent bring more serious reflux problem.
2, the present invention can not increase production cost and just can implement on the basis of existing indoor apparatus of air conditioner, improves the competitiveness of product in market.

Indoor apparatus of air conditioner as above, air-vent is communicated with room air by the hole on installing plate.
Indoor apparatus of air conditioner as above, air-vent is arranged can the air door of open and close.
Indoor apparatus of air conditioner as above, the vertical range on air-vent below between end is less than 6mm.
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, the wall of tangential impeller exhaust air flue is tangential impeller exhaust air flue wall, usual tangential impeller exhaust air flue is made up of the snail tongue of exhaust air flue part and spiral case, 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.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 4, two long limit ends of composition rectangle air-vent with tangential impeller exhaust air flue air-out direction 161 for direction, along exhaust air flue 15 molded line, the long limit being first positioned at the rectangle air-vent on exhaust air flue 15 molded line is top end A, and another corresponding long limit is then for hold B below.
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 a rectangle air port on original exhaust air flue wall, the two long limits in rectangle air port 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 port forms malleation in air port, the object introducing room air can not be reached.So, must by " the top end in air port with hold to stagger below form air-vent ", staggering herein, top end and the exhaust air flue wall-shaped line holding place below, not on same curved line, on this basis, the top end in rectangle air port also must meet specifically " perpendicular to indoor set tangential impeller axial line with holding the relative position structural relation on exhaust air flue wall below, air outlet of indoor set is arranged in the projection plane of lower left side, the clockwise angle that top end is the exhaust air flue wall tangent line positive direction section at point of contact to the line of following end and top end is more than or equal to 10 ° to being less than or equal to 200 ° " this technical characteristic could form air-vent.Refer to accompanying drawing 4, the line of top end projection point A to following end projection point B is top end to the line held below, top end is that the exhaust air flue wall tangent line at point of contact refers to top end projection point A as point of contact, with exhaust air flue wall 15 molded line at end place, the top on top end projection point A tangent line that is point of contact, i.e. 130 in accompanying drawing 4, in accompanying drawing 4 161 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, tangent line crosses point of contact 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 top end projection point A to following end projection point B with point of contact A for initial point, clockwise forwards the angle with this tangent line positive direction section to, and namely in accompanying drawing 4 131, 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 that top end is point of contact, now air-vent is held should be positioned on different straight line molded line below to form setting of staggering.When the top end of air-vent meets such positional structure relation to the following end of air-vent on exhaust air flue wall, air-vent could form negative pressure region, the room air outside air-vent will be introduced into mix with the heat exchange wind in tangential impeller exhaust air flue formed afterwards soft cool heat exchange 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.
" the top end of air-vent with hold perpendicular to indoor set tangential impeller axial line below; air outlet of indoor set is arranged in the projection plane of lower left side; top end and the following line held; the subpoint being positioned to hold below is plane right-angle coordinate initial point, with the counterclockwise 50 ° of angles of the positive direction of X-axis for start line turns in 0 ° to the 200 ° fan section formed counterclockwise again." the essence implication of this technical characteristic is: perpendicular to indoor set tangential impeller axial line, air outlet of indoor set is arranged in the projection plane of lower left side, top end and the line held below, with the subpoint held below for initial point, the number axis of level is X-axis, vertical number axis is in the plane right-angle coordinate of y-axis foundation, be positioned at and turn 50 ° of straight lines forming angles counterclockwise for start line is more counterclockwise between turn 0 ° to the 200 ° fan section formed so that the positive direction of X-axis is first, that is formed air-vent top end and below end to be positioned between this fan section and to meet such relative position structural relation." 0 ° to 200 ° " wherein comprises 0 ° and comprise 200 °.The meaning turning the start line of 50 ° of angles with the positive direction of X-axis counterclockwise refers to from X-axis positive direction number axis and forwards the straight line forming 50 ° of angles with former X-axis positive direction number axis counterclockwise to.If with indoor apparatus of air conditioner left view of the present invention for plane sets up plane right-angle coordinate, then air-vent top end must meet " perpendicular to indoor set tangential impeller axial line with holding below relative position structural relation, air outlet of indoor set is arranged in the projection plane of lower right side, top end and the line held below, with the subpoint held below for initial point, with the number axis of level for X-axis, in the plane right-angle coordinate set up for y-axis with vertical number axis, be positioned at and turn clockwise again between 0 ° to the 200 ° fan section formed with the start line of the clockwise 50 ° of angles of the negative direction of X-axis.”。Both essence implications are identical.Referring to from X-axis negative direction number axis with the meaning of the start line of the clockwise 50 ° of angles of the negative direction of X-axis wherein forwards the straight line forming 50 ° of angles with former X-axis negative direction number axis clockwise to.When air-vent top end with hold below on exhaust air flue wall, to meet such positional structure relation time, air-vent forms negative pressure region, the room air outside air-vent will be introduced into mix with the heat exchange wind in tangential impeller exhaust air flue formed afterwards soft cool heat exchange distinguished and admirable go out air outlet of indoor set realize goal of the invention of the present invention.Meet the setting of the air-vent of this technical characteristic, on air-vent, end drops in a fan section below, thus a lot of relative position organization plan can be had, the blower effect of the air-vent that the organization plan wherein had is arranged is unsatisfactory, be only in the plane right-angle coordinate of plane foundation at the invention described above indoor apparatus of air conditioner right view, when top end and the line held below, with the subpoint held below for initial point, with the counterclockwise 50 ° of angles of the positive direction of X-axis for start line counterclockwise turn in 40 ° to the 160 ° fan sections formed again time, the vacuum effect of the negative pressure region that air-vent of the present invention is formed is just best, also just goal of the invention of the present invention can be realized best." 40 ° to 160 ° " wherein comprise 40 ° and comprise 160 °.When the special case that the molded line of exhaust air flue wall is straight line is arranged, visual exhaust air flue wall is a special camber line.Exhaust air flue wall also can be designed to facing away from tangential impeller direction of axis line arc-shaped bend in theory, but air-out blast is low, and air output disperses.Now, be in the plane right-angle coordinate of plane foundation at the invention described above indoor apparatus of air conditioner right view, top end and the line held below of air-vent, the subpoint being positioned to hold below is plane right-angle coordinate initial point, 0 ° is greater than to when being less than or equal in 65 ° of fan sections formed for start line counterclockwise turns again with the counterclockwise 250 ° of angles of the positive direction of X-axis, can form negative pressure induced wind mouth, but vacuum effect is poor, " being greater than 0 " wherein does not comprise 0 ° yet.
When the spiral case of tangential impeller exhaust air flue wall of the present invention offers air-vent, the top end of air-vent with hold multiple relative position structure to reach the object of the invention below, wherein bending in exhaust air flue with top end, following end 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.When the heat exchange wind that tangential impeller flows out flows to air outlet of indoor set through aduncate air-vent top end, air-vent aduncate top end and the air-vent of following end composition be still positioned on former tangential impeller exhaust air flue wall form negative pressure region, the room air outside exhaust air flue wall will be introduced into continuously to mix with the heat exchange wind in tangential impeller exhaust air flue formed afterwards soft cool heat exchange 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.
After indoor apparatus of air conditioner casing, installing plate is equipped with at the back side, usual installing plate is provided with a square hole of group leader, be generally 2 to 3, rectangle hole communicates with the room air above indoor set, also communicate with the outside of the exhaust air flue wall on tangential impeller spiral case, rectangle hole hangs on the hook on metal hanging wallboard, and wallboard is hung on the wall in advance, and indoor set is exactly be suspended on wall like this.After wallboard hangs up installing plate rectangle hole, rectangle hole is still left enough holes and is communicated with indoor, the present invention arranges air-vent on the exhaust air flue wall of tangential impeller spiral case, so, air-vent has also just communicated with indoor, in addition, under normal conditions, between installing plate and the tangential impeller spiral case at indoor apparatus of air conditioner air intake position, also gap and hole can be there is in the indoor apparatus of air conditioner casing between installing plate and wallboard in vertical direction, existing air-conditioning also has the design tangential impeller spiral case at indoor set air intake position having hole, the all existing indoor apparatus of air conditioner in hole on these gaps and hole and installing plate has, communicate with the outside of the exhaust air flue wall on tangential impeller spiral case, therefore, do not need the setting of special additional air inlet, the existing technology skill of these indoor apparatus of air conditioner is utilized to levy, room air just constantly can attract to come in flow out air outlet of indoor set with after the air of heat exchange mixes as air inlet by these gaps and hole by negative pressure that air-vent is formed in a steady stream.Indoor apparatus of air conditioner of the present invention, all comprises the existing technology skill of these indoor apparatus of air conditioner and levies.Be known technology for linking up with wallboard the hole hung, only there is function originally that hang indoor set, after the arranging of air-vent of the present invention, be just provided with function room air being introduced indoor set exhaust air flue.The mode that the present invention also the indoor set casing above air-conditioner indoor set mounting plate can be established air port newly expands air-vent absorbing quantity of the present invention.Above-mentioned two kinds by air-vent with introduce the gap of room air and hole and air port used for the air inducing mode that communicate of indoor, all be positioned at indoor set top by body of wall position, this gap and hole and between air port and air outlet of indoor set, have indoor set air inlet to be separated by, and air intake direction and indoor set air-out direction angle are greater than 90 °, thus may not produce indoor set air outlet and be back to possibility in these gaps and hole and air port, thus eliminate D patent and bring not only can not to reduce during backflow and can increase because offering additional air inlet the shortcoming that room air reaches design temperature required time and power consumption on the contrary.
The spiral case of tangential impeller is once injection moulding part, air-vent offered by exhaust air flue wall on tangential impeller spiral case, only that a top end is bending in exhaust air flue, following end is still positioned at the rectangle air-vent on former tangential impeller exhaust air flue wall, this rectangle air-vent can generate, so do not increase production cost when the spiral case single injection-molded of tangential impeller.Rectangle air-vent can arrange many below between end connect support bar, become harmonica, the vibration likely brought during to improve the intensity of rectangle air-vent and to reduce air flow at high speed.The heat exchange air that tangential impeller flows out flows out exhaust air flue by refraction on exhaust air flue wall, when the vertical range on rectangle air-vent below between end controls within 12mm, the change of birefringence angle is less, can guarantee that the air-out after reflecting flows to air outlet of indoor set glibly, thus ensure that when not reducing air-out blast, reach the object that air-vent obtains sufficient air inducing.Vertical range on rectangle air-vent below between end refers to hold below into starting point, brings out wind wind path wall or top brings out the crossing air line distance of wind wind path wall camber line extended line to hold the normal of the exhaust air flue wall at place below to top.When the vertical range on rectangle air-vent below between end controls within 6mm, air-out direction after the heat exchange air that tangential impeller flows out reflects on exhaust air flue wall is almost parallel with former air-out refractive direction, air-vent absorbing quantity is larger, does not affect tangential impeller air-out.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.
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.
