Abstract
The present invention provides an air-conditioner indoor unit electric heater fixing device comprising a shell of air-conditioner indoor unit, an electrical heater, the heater is fixed on a fixing device integrated with the shell of the air-conditioner indoor unit. The invention has available effect that the invention improves the fixing device of existing embed type shell of air-conditioner indoor unit, the electric heater is fixed by representing the support made of module with a tightening member integrated with the shell of the air-conditioner indoor unit.
Description
Technical field
What the present invention relates to is air conditioner, particularly be embedded four sides air-out indoor unit electric heater of air conditioner fixture.
Background technology
As shown in Figure 1 and Figure 2, be the fixed form of existing embedded air-conditioner indoor set electric heater.The embedded four sides air-out indoor apparatus of air conditioner structure of existing charged heater comprises: shell 1, evaporimeter 2, chassis 3, fan 4, motor 5, clamp nut 6 and 12, bolt 7; Electric heater support 8,13,15,17,20; Trip bolt 10; Insulation rubber cushion 11; Electric heater 9; Evaporimeter side plate 18,19.Bolt 7 is fixed on the chassis 3 by nut 6, and PTC electric heater support 8,13,14 is installed in it on bolt 7 by insulation rubber cushion 11 and nut 12, and electric heater support 17 and 20 usefulness screws are installed on the baffle plate 18 and 19 of evaporimeter 2.Generally speaking, heat pump type air conditioner is under the heating operation pattern, and air is assisted heating through electric heater 9, to satisfy the defective of winter heating's quantity not sufficient again through after the evaporimeter 2.
The fixed structure of above-mentioned existing embedded air-conditioner indoor set electric heater has following defective: the fixed structure more complicated of electric heater, because of electric heater support the 8,13,15,17, the 20th, mold members, Mould Machining cost height, processing is difficulty relatively, on production line the set-up time long, influence production efficiency.PTC electric heater 9 is along with the increase of face velocity, and heating power increases, because PTC electric heater 9 two ends are in the air-out vortex, promptly is in air-out zone 14,16,21,22 with external position, the air quantity that flows through electric heater 9 two ends herein is less, and wind speed is smaller, is unfavorable for the performance of its performance.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of simple in structure, cost is low, production efficiency is high, only uses fixedly electric heater and give full play to the indoor unit electric heater of air conditioner fixture of PTC electric heater effect of securing member.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of indoor unit electric heater of air conditioner fixture, this device includes: indoor apparatus of air conditioner shell, electric heater, electric heater be fixed on the indoor apparatus of air conditioner shell be on the fixture of one.
The invention has the beneficial effects as follows: the present invention be to existing embedded air-conditioner indoor set electric heater the improvement of fixture, the support that substitutes with the mould manufacturing with the securing member that is fixed as one with the indoor apparatus of air conditioner shell fixes electric heater, reduce the development investment expense, make that the present invention is simple in structure, cost is low, production efficiency is high.In addition, the PTC electric heater 9 of use reduces to some extent with respect to existing length, makes heater 9 place fully in the air outlet zone 14,16,21,22, has increased face velocity, can give full play to the function of PTC electric heater.

The specific embodiment
The invention provides a kind of indoor unit electric heater of air conditioner fixture, this device includes: indoor apparatus of air conditioner shell 1, electric heater 9.Electric heater 9 be fixed on indoor apparatus of air conditioner shell 1 on the fixture of one.
Described fixture comprises: fastener nut 23,27, pad 24, stud 25; The fastener nut 27 that wherein is same as electric heater 9 two ends connecting hole spacings up and down apart is separately fixed on shell 1 lateral surface, one end of stud 25 is combined on the nut 27 after passing shell 1, two connecting hole end faces of electric heater 9 one sides are housed respectively on the locating surface C of stud 25 other ends, and nut 23, pad 24 are fastened on the electric heater 9 after passing stud 25.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
The present invention be to existing embedded air-conditioner indoor set electric heater the improvement of fixture, electric heater 9 is fixed on the indoor apparatus of air conditioner shell 1 by fixture.
Need illustrate to such an extent that be, the parts that structure of the present invention is identical with existing structure are given identical sequence number.Structure of the present invention includes: shell 1, evaporimeter 2, chassis 3, fan 4, motor 5, electric heater 9; Electric heater 9 be fixed on indoor apparatus of air conditioner shell 1 on the fixture of one.
Described fixture as shown in Figure 5, its structure comprises: fastener nut 23,27, pad 24, stud 25.PTC electric heater 9 is installed in 1 four sides of shell of the present invention respectively, make a call to four holes in shell 1 each side, the position in four holes is corresponding with four position of positioning hole on PTC electric heater 9 two ends, electric heater 9 each end have two connecting holes up and down, the size in this hole is of a size of reference with the stud that passes 25, as long as stud 25 is passed.Clamp nut 23 means of spot welds that cooperate with stud 25 after stud 25 1 ends pass shell 1, are tightened on the nut 27 and fix on four holes, shell 1 every side.Electric heater 9 is fixed on shell 1 inboard of stud 25 other ends, stud 25 other ends have locating surface C, two connecting hole end faces of electric heater 9 one sides are close on the locating surface C after passing stud 25 ends, nut 23, pad 24 are fastened on the electric heater 9 after passing stud 25, and electric heater 9 and stud 25 are fixed as one.The fixture of electric heater 9 is same as said structure in shell 1 each side.
Because the electric heater fixture changes, the PTC electric heater 9 that uses reduces to some extent with respect to existing length, make heater 9 place fully in the air outlet zone 14,16,21,22, increased face velocity, can give full play to the function of PTC electric heater.
