According to the air conditioner bottom shell structure provided by the invention, the volute tongue is integrally formed on the bottom shell, so that the volute tongue is prevented from vibrating with the bottom shell under the working condition, and the performance of the whole air conditioner is improved.
Description
Technical field
The present invention relates to air-conditioner fields, and in particular to a kind of air conditioner bottom case structure and air conditioner.
Background technology
In air conditioner, impeller passes through leaf to drive the air on its periphery, by the cold air that evaporator in air conditioner generates
The air outlet in wheel front is blowed to air conditioner.
After wheel rotation, the air around impeller forms vortex under the drive of impeller, and vortex can be with air outlet attachment
Side wall effect generate noise, noise pollution is caused to interior.
For this purpose, Chinese patent CN203349449U discloses a kind of air-conditioning with volute tongue component, the inferoanterior of air outlet
Volute tongue is installed, volute tongue is mounted on bottom case, by volute tongue, can be blocked the vortex generated around impeller, be reduced noise.
In the air conditioner provided in the prior art, as shown in Figure 1, there is overlapping region, still between volute tongue and air outlet
Since the structure of the modern designs of plastics limits, if being molded volute tongue simultaneously in bottom case, volute tongue die cavity depanning to the right in depanning, and under
The upward depanning of die cavity in air outlet direction, volute tongue region and lower air outlet region in vertical direction there are certain overlapping region,
Lead to not in a mold simultaneously by volute tongue and bottom case depanning simultaneously.This make in final air conditioner bottom case and volute tongue it
Between use split settings, between volute tongue and bottom case have gap, when vortex is formed, volute tongue will produce vibration, although eliminating
The noise problem of air conditioner, but result in the abnormal sound of air conditioner.
Invention content
Therefore, the technical problem to be solved in the present invention is to overcome in air conditioner in the prior art between volute tongue and bottom case
By the way of split settings, there are gap between volute tongue and bottom case, cause to occur between volute tongue and bottom case under working condition
The defect of abnormal sound.
For this purpose, the present invention provides a kind of air conditioner bottom case structure, including：Bottom case with air-out passage, the outlet air are logical
Air outlet structure is provided on road；Volute tongue is arranged in the air-out passage, described for eliminating the vortex generated in air duct
Volute tongue is integrally formed on the bottom case, and the air outlet structure and the volute tongue are along the projection of the vertical direction of installation condition
Without overlapping region.
It is removably installed impeller on the bottom case.
The slide construction being slidably matched with base component is provided on the bottom case, the bottom case passes through the slide construction
It is detachably arranged on the base component.
The slide construction is the molding skid parallel with width direction at least one end along its length, the cunning
Sled is contacted with the base component line.
The skid is the circular arc and curved-surface structure consecutively connected to each other for including several groups towards same lateral bend.
The upper limit structure for the cooperation that offsets with the limiting section on the base component is formed at the top of the bottom case.
Impeller with impeller axle is installed on the bottom case, described impeller axle one end is installed in rotation in bottom case,
The other end is sequentially connected with electric machine assembly.
The impeller axle is additionally provided with resetting spring far from described electric machine assembly one end, and the resetting spring is to the impeller
It is applied with the biasing force towards the electric machine assembly.
Present invention simultaneously provides a kind of air conditioners comprising：Base component, fan electromotor are removably installed in the base
On base member；Bottom case, is mounted on the side of the base component, and the bottom case is detachably arranged in described by slide construction
Base component, and the impeller of the bottom case is removably attachable on the fan electromotor.
Technical solution of the present invention has the following advantages that：
1. air conditioner bottom case structure provided by the invention, the volute tongue is integrally formed on the bottom case, and the outlet air
Mouth structure and the volute tongue along the vertical direction of installation condition projection without overlapping region.
Split settings are used in final air conditioner between bottom case and volute tongue, there is gap between volute tongue and bottom case, work as whirlpool
When rotation is formed, volute tongue will produce vibration, result in the abnormal sound of air conditioner.
The air conditioner bottom case structure provided through the invention, since volute tongue is integrally formed on the bottom case, to avoid
Volute tongue shakes between bottom case under working condition.
2. air conditioner bottom case structure provided by the invention, the slide construction is molding at least one end along its length
The skid parallel with width direction, the skid are contacted with the base component line.The skid be include several groups direction
The circular arc of same lateral bend and curved-surface structure consecutively connected to each other.
Pass through the skid of setting in curved surface so that when base component is connect with bottom case, belong to the contact a little with face, it is such
Contact of the basal profile compared to conventional face with face, can significantly decrease and be caused under the conditions of industry control, due to expanding with heat and contract with cold
Rubbing surface between frictional noise.
