DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for cleaning the bottom of a drum of a tea rubbing and drying apparatus having a rubbing machine such as a rough rubbing machine, a middle rubbing machine, and a middle rubbing machine.

[0002]

BACKGROUND OF THE INVENTION Conventionally, the inside of a tea making and drying apparatus such as a tea making and roughing machine has been washed at every suitable use time.
This is because while tea is being produced, deposits such as tea astringent and tea scum increase between the duck at the bottom of the trunk and the spatula of the massager and on the surface of the spatula. If this is left as it is, the adhering matter is mixed into the processed tea leaves in an over-dried state, deteriorating the quality of the product tea leaf, and leaving the adhering matter for a long time is not good for hygiene.

[0003] As a conventional washing mode in a tea making and drying apparatus, there is Japanese Utility Model Publication No. 53-12800, for example. In this embodiment, a straight brush-shaped body bottom cleaning tool 40 'as shown in FIG. 5 is described as a cleaning tool for the drum 5a' on the body bottom 4 'of the massaging and drying cylinder 3', and the massager 10 ' A linear brush-shaped spatula cleaning tool 20 'is described as a cleaning tool for the spatula 10A'. As a mode of using these, washing is performed at appropriate tea making time intervals. First, a body bottom cleaning tool 40 'is attached to the tip of the leaf dredge 11', and hot water W 'is poured into the kneading and drying cylinder 3'. , The main shaft 9 'is rotated so that the drum 5a'
Is washed. When the cleaning of the bottom 5a 'of the trunk bottom 4' is completed, the trunk bottom cleaning tool 40 'is removed, the front management door 8' is opened, and the spatula cleaning tool 20 'is moved to the machine frame below the front management door 8'. And the spatula 10A 'is washed.

[0004] The above-described cleaning structure and mode in the tea making and drying apparatus have the following disadvantages, and further improvements have been desired. For example, in the cleaning of the dust 5a 'by the above-described trunk bottom cleaning tool 40', a portion where the attached matter A 'was not completely removed from the dust 5a' remained. In addition, the deposit A '
Some were removed and washed, while others were not washed forever. This may be due to the difference in adhesion between the deposits A ', but there is also a problem on the trunk bottom cleaning tool 40' attached to the leaf dredge 11 '. That is, when it is required that the cleaning power of the body bottom cleaning tool 40 ′ is uniform, the distance between the tip of the leaf dredge 11 ′ to which the body bottom cleaning tool 40 ′ is attached and the duct 5 a ′ depends on the rotation angle. It is required that the positions be always at the same interval. However, in practice, for example, the leaf dredge 11 'and the main shaft 9' are slightly warped due to long-term use, so that they are no longer completely equidistant, so that the trunk bottom cleaning tool 40 'comes into contact with the duct 5a'. Some places do not. Therefore, if the body bottom cleaning tool 40 'is positioned close to the duck 5a' side and the contact pressure is set to a high value, the location of the body bottom cleaning tool 40 'is reduced where the distance between the leaf dredge 11' and the duck 5a 'is short. The reaction force received increases. This causes a failure of the leaf dredge 11 'and its drive system. Conversely, the body bottom cleaning tool 40 '
Is positioned in a direction away from the duct 5a 'and the contact pressure is set weak, the cleaning effect is reduced. In any case, it is difficult to make the pressure of the body bottom cleaning tool 40 'uniform over the entire surface of the duct 5a'. Therefore, if anything, the contact pressure was set low so as not to cause a failure, a sufficient cleaning action could not be obtained, and a long cleaning time was required.

[0005]

[Technical Problem Attempted to Be Developed] The present invention has been made in view of such a background, and it is intended to make the cleaning action of the body bottom cleaning tool substantially uniform over the entire surface of the duck and to give an impact to the leaf dredge and its drive system.

In the cleaning structure for performing cleaning, the trunk bottom cleaning tool is attached to the massager or the leaf dredge while being biased by a biasing member against the trunk bottom. According to the present invention, since the trunk bottom cleaning tool is urged against the trunk bottom, the cleaning tool always contacts the trunk bottom and contacts the trunk bottom with a substantially constant pressure for cleaning. Since the body bottom cleaning tool is urged, the contact pressure with the duck is rather high, so that the cleaning action is excellent and the cleaning time can be shortened. In addition, since the reaction force received from the duck is absorbed by the biasing member, it does not give a shock to the leaf dredge or massager or its drive system,
There is no cause of failure. In addition, since the attachment of the trunk bottom cleaning tool is not required to be strict as in the related art, anyone can easily and quickly set the uniform cleaning action and attach the trunk bottom cleaning tool.

[0007] In addition, the structure for cleaning the bottom of the drum in the tea kneading and drying apparatus according to claim 2 is characterized in that, in addition to the above requirements, the urging member is a leaf spring. According to the present invention, since the urging member is a leaf spring, the adhered substance is less likely to adhere to the urging member itself than a coil spring or the like, and even if it adheres, it can be wiped off immediately after cleaning.

[0008] Further, the cleaning structure of the trunk bottom in the tea making and drying apparatus according to claim 3 is characterized in that, in addition to the above requirements, the trunk bottom cleaning tool is a brush, and the hair is implanted in a spiral shape. Things. According to the invention,
The attached matter attached to the bottom of the trunk is scraped off in the horizontal direction as well as in the vertical direction, and the action of removing the attached matter is further increased.

Further, in the tea brewing and drying apparatus according to a fourth aspect of the present invention, in addition to the above-mentioned requirements, the drum stretched on the inner surface of the trunk bottom is made of a fluororesin or coated with a fluororesin. It is characterized by the following. According to the present invention, the adhesion of the adhered substance to the duck is weakened, so that the adhered substance is easily removed.
