However, it will be taken out through the insertion hole 42. In this case, the condenser filter 50 is bent so as to be temporarily bent while being pulled obliquely forward, and the left end portion 52c and the right end portion 52d of the filter frame 52 are partially inserted into the insertion hole groove portion 422 of the insertion hole portion 42. The frictional force generated between the insertion hole 42 and the filter frame 52 is reduced.

  As described above, according to the kick plate 40 according to the present embodiment, the elongated hole-shaped insertion hole portion 42 formed in the upper portion of the ventilation region 40a allows the condenser filter 50 to be inserted. In addition, the insertion hole groove 422 at the end allows entry of the left end 52 c and the right end 52 d of the filter frame 52 of the condenser filter 50, and the support 43 is located between the ventilation hole 41 and the condenser 23. Since the condenser filter 50 inserted through the insertion hole 42 is supported, the condenser filter 50 can be easily attached and detached without removing the kick plate 40. Therefore, the cleaning frequency of the condenser filter 50 can be improved, and the operating efficiency of the refrigeration equipment of the compressor 22 and the condenser 23 can be improved.

  According to the kick plate 40, the insertion hole portion 42 is formed in a mode in which the left-right direction is the longitudinal direction above the ventilation region 40a, and the insertion hole groove portion 422 extending downward is formed at both ends. Therefore, the condenser filter 50 can be inserted downward into the insertion hole portion 42 and supported by the support portion 43, and the condenser filter 50 can be pulled out upward. Considering that the machine room 10b is installed in the lower area of the main body 10, workability can be improved.

  According to the kick plate 40, since the support portion 43 supports the handle portion 53 so as to be exposed from the insertion hole portion 42, the operator can easily take out the condenser filter 50 by holding the handle portion 53. This also improves the workability.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.
