The use of a mold structure in which the mold is slid in two steps for the part 12 prevents warpage and sink of the nose part. These structures are disclosed in
As described in Japanese Patent No. 9706, the basic structure is such that the nose portion and the dew tray are integrally formed, and the left and right wind direction plates and the interlocking plate are separately formed and combined.

る。As shown in FIG. 7, a conventional discharge block has a structure in which a dew tray and a nose portion are integrally formed, and several left and right wind direction plates are interlocked with each other. Because it has a structure in which the connected components are installed with the up-and-down wind direction plates and the insulation material for the dew tray, the number of parts is large, the assembly work takes time, and the cost increases.

いう問題もあった。Further, since the dew receiving tray and the nose portion are integrally formed, the nose portion hardly absorbs the deformation due to a temperature change during operation, and the gap between the nose portion and the through-flow fan changes, so that the air blows. This deteriorates the performance and causes a decrease in the air volume and generation of abnormal noise. In addition, there is also a problem that the mold structure of the nose portion becomes complicated, so that the structure tends to cause warpage and sink marks.

The molded part made of polypropylene tends to be worse with respect to the warpage and sink marks of the nose part, but the exposed pan is made of a less warped material or a highly rigid one formed by gas injection. The structure is such that the warpage of the nose portion is corrected by combining the above. In addition, when incorporating the nose of a polypropylene molded product into the dew tray, the nose is made smaller in the longitudinal direction and a clearance is provided to absorb the deformation of the nose due to temperature change during operation. It is.

Can be reduced to Also, by adopting a structure in which the dew receiving pan and the nose part are separated and combined, the undercut part is eliminated in the dew receiving pan and the nose part, so that a nose part having a constant thickness can be formed. Is simplified, the formability is improved, and a highly reliable discharge block capable of absorbing the deformation of the nose due to a temperature change during operation can be provided.

を示したのが図２である。The discharge block 4 is composed of a dew receiving tray 4d for receiving condensed water, a left and right plate 4a, an interlocking plate 4b for linking several left and right wind plates, a vertical plate 4e, and a nose 4c. The nose, the left and right wind direction plates, and the interlocking plate are integrally molded products using the effect of the polypropylene's twist.The dew tray is provided with a hollow portion by the gas injection method to increase rigidity and to prevent warpage and sink marks. It has a structure that prevents it and improves dimensional accuracy. FIG. 2 shows a cross section of the air conditioner.

Therefore, the gap management of this portion is important in manufacturing. As described above, the component constituting the nose portion is a discharge block.
As shown in Fig. 3, since the nose, left and right wind direction plates, and interlocking plate are integrally molded products using the effect of polypropylene, the product warps in the direction of the arrow after molding. Since the structure is combined with a dew tray having high rigidity, warpage of the nose can be corrected.

The structure is such that the influence on the nose gap X is reduced. The clearance between the two components at this time is determined by the longitudinal dimension and the expansion coefficient of the components.

し、信頼性の高い吐出ブロックを提供できる。As is apparent from the above description, the present invention relates to a discharge block structure for an indoor unit of an air conditioner, in which the nose portion, the left and right wind direction plates, and the interlocking plate are integrally formed by using a polypropylene twisting function. The number of parts can be reduced and the assembly workability can be improved by using the product. Also, the nose part that is easily warped because of polypropylene is combined with the dew tray provided with a hollow part by a highly rigid gas injection method. By doing so, the warpage of the nose is corrected. Further, in the related art, the nose portion is deformed under the influence of a temperature change during operation and the nose gap is changed to cause a decrease in the blowing performance. However, the present invention separates the dew tray and the nose portion from each other. By providing a clearance in the longitudinal direction, deformation due to a temperature change of the nose portion is released in the longitudinal direction, and a stable nose gap which is not affected by the temperature change can be secured. By having a structure in which the dew tray and the nose part are separated and combined, the undercut part is eliminated and a nose part shape having a constant thickness can be formed. Is simplified and the moldability is improved, so that the shape of the nose is stable and a highly reliable discharge block can be provided.
