Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device provided in a frozen dessert producing apparatus for producing a semi-solid frozen dessert represented by a soft serve ice cream, and particularly to a cylinder for producing a frozen dessert. The present invention relates to a safety device that prohibits the operation of a frozen dessert stirring and extruding member (dasher) in the cylinder when the opening is in an open state.

[0002]

2. Description of the Related Art Conventionally, in a frozen dessert producing apparatus for producing a semi-solid frozen dessert such as a soft ice cream or a shake, a frozen dessert raw material is usually supplied inside, and the frozen dessert raw material is cooled while stirring. A cylinder is provided for manufacturing.

Usually, the cylinder has a substantially cylindrical shape, and is arranged in the casing such that the longitudinal direction thereof is substantially horizontal along the front-back direction of the frozen dessert manufacturing apparatus. A stirring blade (stirring member / dasher) rotatable around the shaft is provided in the cylinder, and a cooler is provided around the cylinder. Therefore, after supplying the frozen dessert raw material into the cylinder, the frozen dessert such as soft cream is manufactured by cooling by the cooler and stirring by rotating the stirring blade. Furthermore, the stirring blade is
When the frozen dessert is taken out, it also functions as a frozen dessert extruding member that pushes the frozen dessert from the cylinder to the taking-out mechanism.

The front end of the cylinder is an opening, and is closed by a front cover (cover member) having a take-out mechanism. The front lid portion is also provided with a front bearing that rotatably supports the shaft portion of the stirring blade. That is, the shaft portion of the stirring blade is supported at a position where it can be appropriately rotated by the front lid portion attached to the opening.

That is, unless the front lid is attached to the opening, the front shaft of the stirring blade cannot be provided. Therefore, if the stirring blade rotates without the front lid being attached, the rotation of the stirring blade becomes very unstable and the inside of the cylinder is damaged.

Therefore, as a technique for preventing the occurrence of the above problems, various techniques for detecting whether or not the front lid portion is attached to the opening have been proposed. Specifically, there is a technique of providing a detection unit that detects whether or not the front cover is attached to the opening. Usually, in a frozen dessert manufacturing apparatus provided with such a detection means, rotation drive of the stirring blade is prohibited unless the front lid is attached to the opening.

As a typical example of the above-mentioned detecting means, for example, there is a structure in which a magnet is provided in a part of the front lid portion and a safety switch corresponding to the magnet is provided on the casing side. With this configuration,
The safety switch is turned on when the magnet approaches, while the safety switch is turned off when the magnet moves away. Therefore, if the front lid is not attached, the magnet does not exist, so the safety switch is turned off, and as a result, the rotational drive of the stirring blade is prohibited.

Further, in Japanese Patent Laid-Open No. 10-136906, at least three tact switches are provided as detection means at the mounting portion of the front lid portion of the casing, or an optical detecting device for irradiating the mounting portion is provided. Is disclosed.

In the structure in which the tact switch is provided, the contact of each tact switch is slightly projected from the mounting surface, and when the front lid is attached, the plurality of contacts come into contact with the front lid to turn off the tact switch. Replace In the technique of the above publication, since there are three or more tact switches, all three contact elements are in sufficient contact with the front lid part to switch all the tact switches, so that the mounting state of the front lid part is changed to "surface". Can be detected as
The mounting state can be detected more accurately. Therefore, even if only one contactor is not in sufficient contact, the attached state cannot be detected as a "face", and the rotational drive of the stirring blade is prohibited.

Further, in the structure provided with the optical detecting means,
By irradiating the mounting part with light, the mounting state of the front cover part is detected. If the front cover part impedes the irradiation of light, the rotation drive of the stirring blade operates, but the irradiation of light does not occur. If it is not hindered, the rotational drive of the stirring blade is prohibited because the front lid is not attached.

By providing the detecting means as described above, when the front lid is not attached, for example, when washing the frozen dessert making apparatus or during other maintenance,
It is possible to prohibit the rotational drive of the stirring blade by inadvertently touching the operation switch.

[0012] In any of the above techniques, if the detection means detects that the front lid is not attached, not only the rotational drive of the stirring blade is prohibited, but also a display means is provided in the frozen dessert manufacturing apparatus. By
It is also possible to notify the user by displaying "The front lid is not attached".

[0013]

However, in the prior art represented by each of the above-mentioned technologies, whether or not the above-mentioned detection means is provided in the frozen dessert manufacturing apparatus is as follows.
Not clear in appearance. For example, in the technology using the magnet-safety switch, the detection means is provided at the position where the front lid portion and the casing face each other. Therefore, it is possible for the user to visually determine whether or not the attachment of the front lid portion is detected. I hardly understand.

Therefore, in the above-mentioned conventional technique, the user is less conscious of the detection of the attachment of the front lid portion, and as a result, the attachment of the front lid portion is very important for the rotation of the stirring blade. Becomes difficult to be aware of. In addition, since the detection means is almost unknown in appearance, it is completely defensive for the user to unknowingly form the same conditions as when the front lid is attached, and malfunction of the stirring blade is prevented. It cannot be prevented more reliably.

Similarly, in the technique disclosed in Japanese Unexamined Patent Publication No. 10-136906, the tact switch is provided on the mounting portion of the front lid portion, and it is unknown whether or not there is a detecting means in appearance, and optical detection is performed. As for the device, it is only provided around the mounting portion and irradiates the mounting portion. Therefore, the user does not have to be aware of the detecting means again when attaching the front lid portion, and the detecting means is almost unknown in appearance.
It also becomes difficult to reliably prevent malfunction of the stirring blade.

In the first place, if the stirring blade rotates without the front lid being attached, not only the inside of the cylinder is damaged, but also the rotation of the stirring blade may cause an injury accident such as injury to a user. Therefore, when preparing the operation of the frozen dessert manufacturing apparatus, whether or not the front lid is attached is very important in terms of safety.

Here, in the above-mentioned conventional technique, it is simply detected whether or not the front lid portion is attached to the opening because of the configuration, and the attachment of the front lid portion is detected. No consideration has been given to appealing to the user to call attention to the importance and safety of mounting the front lid. As a result, in the conventional configuration, the detection means is provided in a “hidden” position when viewed from the user, or has a configuration that is difficult to understand in appearance.

Considering that it is very important whether or not the front lid is attached during the operation of the frozen dessert manufacturing apparatus, the existence of the detecting means is more unclear than that of the detecting means. If the existence is clear, the user can be made aware of the importance of attaching the front cover. Therefore, it is possible to further raise awareness regarding safety when operating the frozen dessert manufacturing apparatus.

In particular, in recent years, semi-solid frozen desserts such as soft ice cream and shakes meet the recent preference for soft-touch mouthfeel. The user base of has expanded compared to before. If the user base is not so wide as before, most of the users are familiar with frozen dessert making equipment, and it is considered that the conventional technology described above was sufficient for safety, but the user base will expand further in the future. If so, the number of users who are not accustomed to the frozen dessert manufacturing apparatus may increase, and therefore, further enhancement of safety is required in the frozen dessert manufacturing apparatus.

The present invention has been made in view of the above problems, and an object of the present invention is not only to prohibit the operation of the frozen dessert making apparatus in a state where the front lid portion is not attached, but also to By making it clear that the attachment is detected, the safety device of the frozen dessert making device that makes the frozen dessert making device more safe to use for the user and consequently allows the frozen dessert making device to be used more safely is provided. Especially.

[0021]

From the direction different from the mounting direction to the mounting position of the lid member
With changing the third position is projected is a position that enables contact with the lid member, in the third position, characterized in that the switching means is switched to the safe operation of prohibiting the operation of at least the stirring means I am trying.

According to the above construction, the plunger position detecting means is brought into contact with a part of the lid member when the lid member is attached. Therefore, the plunger position detecting means is designed so that the attachment of the lid member is once hindered, or even if it is not hindered, the contact state can be known to the user at the time of attachment.

Conventionally, even if the detecting means is provided, it is simply detected whether or not the lid member is attached. However, with this method, no attention was paid to the attachment of the lid member, which is important for ensuring the safety of the frozen dessert manufacturing device, before or during the attachment of the lid member.

On the other hand, in the present invention, as described above,

Therefore, the presence of the detection means is clear from the viewpoint of the user, and at the time of attachment, one action is added to the work of attaching the lid member, such as pushing up the plunger position detection means to release the contact. As a result, it is possible to give the user an opportunity to reconfirm the ensuring of safety by attaching the lid member.

Further, since the lid member is attached after the contact of the plunger position detecting means is released, the user can always be aware that a safety mechanism for safe operation is provided, and as a result, the lid is attached. The user's attention can be directed to the work of attaching the members. Therefore, with the lid member not attached,
The safety of the frozen dessert manufacturing apparatus can be further improved by more surely avoiding inadvertent rotation of the stirring means.

In the safety device for a frozen dessert manufacturing apparatus according to a second aspect of the present invention, in addition to the above configuration, the plunger position detecting means is a lever having a substantially rod shape,
The tip portion of the lever contacts the part of the plunger, and the position changing means changes the tip portion of the lever to the first, second and third positions. There is.

It is characterized in that when the lid member attachment detecting means is in the lowered position, it can be switched to a safe operation for prohibiting at least the operation of the stirring means by the switch means.

According to the above construction, since the lid member attachment detecting means takes the lowered position, the lid member attachment detecting means is set to the lowered position when the lid member is attached, so that the lid member is once attached. Is blocked by the attachment detection means,
Alternatively, the user can see the contact state at the time of installation without any obstruction.

Therefore, the existence of the lid member attachment detecting means becomes clear from the viewpoint of the user, and the lid member cannot be attached to the opening as it is, or the lid member attachment detecting means clearly contacts the lid member. It will be in the state of being. Therefore, one action such as pushing up the lid member attachment detecting means is added to the work of attaching the lid member, and as a result, the user can be given an opportunity to reconfirm the securing of safety by attaching the lid member. it can. Also,
By adding the one action, the user can always be aware that the safety mechanism is provided, and as a result, the user's attention can be directed to the work of attaching the lid member.

In order to solve the above-mentioned problems, a safety device for a frozen dessert producing apparatus according to a fourth aspect of the present invention has an agitating means inside, and a part of the agitating means becomes an opening and is closed by a lid member.

Reference numeral 2 is a switch for switching between two operations in the normal control (normal operation operation and frozen dessert operation).

As shown in FIG. 3, the terminal holding portion 19c has a structure in which a pair of opposing wall surfaces are provided substantially perpendicular to the base surface, and the wall surfaces have a constant interval.
Therefore, the cross section of the terminal holding portion 19c is substantially U-shaped. Each of the pair of wall surfaces is provided with a hole (not shown) so that the rotary shaft 18c can pass therethrough while the rear end portion is sandwiched at regular intervals.
That is, the terminal holding portion 19c and the second contact terminal 19b
Is the same as the plunger position detection lever 18b.
8c is movably supported with 8c penetrating the hole.

Here, the plunger position detecting lever 18b
Since the terminal holding portion 19c and the terminal holding portion 19c are separate members, the plunger position detection lever 18b and the first contact terminal 19a, and the terminal holding portion 19c and the second contact terminal 19c.
It is possible to move independently of each other with respect to the rotation axis 18c.

The first contact terminal 19a or the second contact terminal 19b is biased by a spring 19d or a spring 19e, respectively. This way of energizing,
That is, the shape, number, and mounting method of the springs 19d or 19e with respect to the first contact terminal 19a and the second contact terminal 19b are not particularly limited, and the first contact moved in the rotation direction about the rotation shaft 18c. The terminals 19a and the second contact terminals 19b may be biased so as to return to their original positions, and the plunger position detection lever 18b connected to these contact terminals may be in a fixed position (the lowest position described later). Further, various biasing means other than the spring may be used.

Further, in the present embodiment, the switch unit 1
8a has a structure including a safety switch 181 and a normal switch 182, but the present invention is not limited to this. That is, as will be described later, it suffices if switch means capable of switching between a safe operation, a normal operation and a frozen dessert operation is provided corresponding to the three positions of the plunger position detection lever 18b, and the number of switches and attachment thereof are provided. The above configuration and the like are not particularly limited.

In the safety device according to the present embodiment, the position changing mechanism 19 included in the take-out switch mechanism 18 allows the tip of the plunger position detecting lever 18b to take three positions. Therefore, normal operation prohibition control (that is, safety control) when the front cover 16 is not attached
And normal control (control for normal operation and frozen dessert operation and switching of these operations) can be switched by one switch means (extraction switch mechanism 18).

Specifically, the plunger position detecting lever 1
Since the tip of 8b has three positions, at least in the operation of the frozen dessert manufacturing apparatus, a safety operation (safety control on), a normal operation operation (safety control off / normal control), and a frozen dessert operation (safety control off It is possible to switch between three operating states (normal control).

The safety control is a safety control which prohibits at least the rotating operation of the stirring blade 13 and, depending on the situation, prohibits the operation of the cooler 15 and the operation of other controllable means by the control unit 20. Refers to. On the other hand, the normal control is a control relating to a frozen dessert manufacturing operation and a taking-out operation, and at least the stirring blade 13 is rotated and the cooler 15 is operated to produce a frozen dessert, and at least the stirring blade 13 is operated. This refers to control including two operations of a frozen dessert extracting operation for rotating and pushing the frozen dessert from the cylinder 12 to the extracting mechanism 17. The safety control ON state has priority over the normal control ON state.

First, in the safety operation, as shown in FIG. 1, the plunger position detecting lever 18b is completely lowered, that is, the plunger position detecting lever 18b.
Is in a state in which the tip portion of is located at the lowest position (the lowest position / third position). Next, in the normal operation, as shown in FIG. 5, the plunger position detection lever 18b has its tip portion slightly above the safety state (intermediate position / second position).
Position). Then, in the frozen dessert taking-out operation, as shown in FIG. 6, the plunger position detection lever 18b is in a state in which the tip thereof is located at the uppermost position (uppermost position / first position).

A conventional structure (for example, the above-mentioned Japanese Patent Laid-Open No. 10-1)
In the case of the technology of Japanese Patent No. 36906), the tip of the plunger position detecting lever 18b can only take two positions corresponding to the uppermost position and the intermediate position defined in the present embodiment. On the other hand, in the present invention, the plunger position detecting lever 18b can be set at three positions, particularly, the lowermost position defined in the present embodiment. Therefore, this lowest position can be used as a position related to switching of safety control.

As a result, in the safety device according to the present invention,
Unlike the conventional case, it is not necessary to separately provide a structure for safety control, and the entire structure of the frozen dessert manufacturing apparatus can be simplified. Further, the plunger position detection lever 18b also has a function as a detection means for detecting the attachment of the front lid portion 16, and since it is provided above the front lid portion 16, the presence of the detection means can be seen by the user. Therefore, the importance of attaching the front lid 16 can be reconfirmed, and the user unknowingly forms the same condition as when the front lid 16 is attached.
It is possible to more reliably avoid a situation in which 3 malfunctions.

Moreover, as will be described later, the lowermost position, which is the tip of the plunger position detecting lever 18b, is a position where the attachment of the front cover 16 is hindered.
Of course, in the configuration of the present invention, the tip can be moved from the lowermost position to the intermediate position or higher. However, once the front cover 16 is prevented from being attached in this manner, the front cover 16 can be prevented. When attaching, the user can be given an opportunity to reconfirm the securing of safety by attaching the front lid portion 16. As a result, it becomes possible to efficiently carry out appropriate operation preparation.

In the present embodiment, the front lid 1
When installing 6, the plunger position detection lever 18b
It suffices that the front end portion can be brought into contact with the front lid portion 16, and does not necessarily obstruct the attachment of the front lid portion 16. That is, the front cover 1
Although smooth mounting is possible without hindering the mounting of 6, it is sufficient if the user can clearly recognize the contact state at the time of mounting. This point will be described in detail in the third embodiment.

Next, regarding the control and operation of the safety device according to the present embodiment, regarding the position change of the tip end portion of the plunger position detection lever 18b and the switching of each operation state in the position change mechanism 19, the front cover portion is described. 16
Will be described based on the attachment to the opening 12a.

Lowermost Position (Third Position) First, when the front lid 16 is attached to the opening 12a in the open state, the front lid 16 is attached to the opening 12a. Bolt of 12
c (see FIG. 1, FIG. 5, FIG. 6, etc.), the holes (not shown) formed in the front lid portion 16 are aligned with each other, and the front lid portion 16 is set to the opening 12a. It will be pushed in.

However, as shown in FIG. 1, when the front cover 16 is not attached, the plunger position detecting lever 18b is moved to the lowermost position, which is a fixed position, by urging the springs 19d and 19e. Has become. Therefore, the tip portion thereof can contact the front lid portion 16 in the vicinity of the opening 12a when the front lid portion 16 is attached, separately from the position of the plunger 17d.

That is, in the present embodiment, the plunger position detecting lever 18b functions as a projecting member, and if the front lid 16 is not attached, the tip end thereof is attached to the attachment position of the front lid 16 (opening 12a). Such a position) is taken to be the lowest position that protrudes excessively.

In such a lowermost position, the tip portion is
It is located above the opening 12a so as to prevent the front lid 16 from being pushed in. In FIG. 1, the upper portion of the frame portion of the front lid portion 16 that is in contact with the opening 12a is in contact with the front end portion so as to be caught by the tip portion. Therefore, the front lid 16 is once prevented from being attached to the opening 12a by the tip portion.

In the position changing mechanism 19 in this state,
As shown in the upper part of FIG. 7A, first, the rear end portion (which is the bent portion as described above) of the plunger position detection lever 18b is in a substantially vertical state. Therefore, each of the first contact terminal 19a and the second contact terminal 19b provided at the rear end portion is in a position where it stands upright substantially vertically to the horizontal direction.

As shown in the lower part of FIG. 7A, the first contact terminal 19a and the second contact terminal 19b are both safety switches 1 in the switch section 18a.
81 and the switch terminal 181a of the normal switch 182
The switch terminal 182a and the switch terminal 182a are in contact with each other.

At this time, when the front lid 16 is attached, it is in a preparatory stage for operating the frozen dessert manufacturing apparatus. Therefore, the entire frozen dessert manufacturing apparatus is not powered on, or even if it is on, some operation switch or the like is operated. Unless the operating means is operated, normal control cannot be performed. However, even when the front cover 16 is not yet attached, there is a possibility that a normal operation becomes possible due to an erroneous operation such that the power is accidentally turned on or the operation switch is operated.

On the other hand, when the tip end portion is at the lowest position, the operation state of the frozen dessert manufacturing apparatus is changed to the safety operation by switching the safety switch 181, so that the front lid portion 16 is attached to the control portion 20. If it is determined that the stirring blade 13 has not been rotated, at least safety control for stopping the rotation of the stirring blade 13 is performed.

On the other hand, the normal switch 182 is switched to correspond to the normal driving operation,
Since the safety control is performed by the safety switch 181, even if the normal control is accidentally enabled, the safety control is prioritized and the normal operation is not performed, and therefore the stirring blade 13 does not rotate.

Intermediate Position When the tip of the plunger position detecting lever 18b is at the lowermost position as described above, the attachment of the front lid 16 is once hindered. Therefore, in order to attach the front lid portion 16 to the opening portion 12a, it is necessary to move the tip portion above the intermediate position. Then, as shown in FIG. 8, the user pushes up the tip portion with a finger or the like (arrow D
Direction), after moving to the intermediate position or more (up to the uppermost position in FIG. 8), the front lid portion 16 is pushed toward the opening 12a side (arrow E direction). As a result, the front cover 16 is
It is securely attached to the opening 12a.

As shown in FIG. 5, the front lid portion 16 attached to the opening 12a has a bolt 12c and a nut 1 attached thereto.
By attaching 2d, it is completely fixed to the opening 12a. At this time, since it is not necessary to push up the tip of the plunger position detection lever 18b, the user releases the state in which the tip is pushed up with a finger (the state shown in FIG. 8). As a result, as shown in FIG.
The front lid portion 16 comes into contact with the upper end portion of the plunger 17d. In this contact state, the position of the tip of the plunger position detection lever 18b is the intermediate position.

At this intermediate position, the plunger position detecting lever 18b moves slightly upward from the fixed position (the lowermost position) about the rotary shaft 18c. Accordingly, in the position changing mechanism 19, as shown in the upper diagram of FIG.
The rear end of the plunger position detection lever 18b is slightly inclined (for example, the angle θ ₁ ), and the first contact terminal 19a directly attached to the rear end is also inclined.

On the other hand, since the second contact terminal 19b is provided at the rear end portion via the terminal holding base 19c, the rear end portion of the terminal holding base 19b is inclined at an angle of about θ _1.
The terminal holding base 19c and the second contact terminal 19 are not contacted with the base plate surface of c or lightly contacted as shown in the figure.
b is hardly tilted. Therefore, the second contact terminal 19b is held in an upright state that is substantially vertical to the horizontal direction, as in the lowermost position. Therefore, as shown in the lower diagram of FIG. 7B, of the two switches included in the switch unit 18a, only the safety switch 181 is switched by the first contact terminal 19a.

As described above, the safety switch 181 is for switching on / off of the safety control. Therefore, at the intermediate position, the safety control is released (off) by switching the safety switch 181. Therefore, the control section 20 determines that the front cover section 16 is attached, and the normal control becomes possible depending on whether the power is turned on or some operation switch is operated. In this state, since the switching state of the normal switch 182 corresponds to the normal operation operation, the normal operation of the stirring blade 13 and the cooler 15 can be started in the state where the normal control is performed.

In this way, the plunger position detection lever 1
When the tip portion of 8b is at the lowermost position, the control of the control unit 20 becomes safety control by switching the switch portion 18a, while at the intermediate position, the safety control is released and normal control is performed (normal operation and frozen dessert). Control of take-out operation).

In the present embodiment, the attachment of the front lid portion 16 is once hindered when the tip portion is at the lowermost position, but this is due to the detection means for detecting the attachment of the front lid portion 16 (in this case, , Plunger position detection lever 1
8b) is provided at a position "easy to understand" for the user. Moreover, since one action is added to the work of attaching the front cover 16 such as pushing up the plunger position detection lever 18b to release the contact, the front cover 16 is attached to the user when the front cover 16 is attached. Attention is drawn to the installation of 16. As a result, the front lid 16 is properly attached, and the frozen dessert making apparatus can be more efficiently prepared for operation.

Further, since the front cover 16 is attached after the plunger position detection lever 18b is released from contact, the user can always be aware that a safety mechanism for safe operation is provided. As a result, the user's attention can be directed to the work of attaching the front lid 16.

Moreover, since the safety control is not released unless the front lid 16 is securely attached, the stirring blade 13 does not rotate carelessly, and the user's attention to safety is also called up. Therefore, it is possible to more surely avoid the inadvertent rotation of the stirring blade 13 and to more reliably prevent the damage and injury of the cylinder 12.

When the uppermost front cover 16 is securely attached, the safety control is released and the normal control becomes possible. Therefore, the normal control can be performed by turning on the power or operating a specific operation switch. Be implemented. Here, in the intermediate position,
Since the normal operation is performed, the rotation of the stirring blade 13 and the cooling of the cylinder 12 by the cooler 15 are performed as usual. After that, when the completion of the frozen dessert is detected in the cylinder 12 by an unillustrated frozen dessert production state detecting means or the like, the user can take out the frozen dessert.

When the frozen dessert is taken out, as shown in FIG. 5, the take-out lever 17e is pushed down from the position indicated by the solid line to the position indicated by the chain double-dashed line (direction of arrow C) to move the interlocking plunger 17d upward (direction of arrow A). Direction),
The extraction pipe portion 17a and the cylinder 12 are communicated with each other through the through hole 17b (see FIG. 2).

When the take-out lever 17e is pushed up to take out the frozen dessert from the cylinder 12, the frozen dessert making apparatus is switched from the normal operation to the frozen dessert taking-out operation for taking out the frozen dessert.

That is, as shown in FIG. 6, the take-out lever 1
When 7e is pushed up, the plunger 1
The position of the upper end of 7d rises, and therefore the position of the tip of the plunger position detection lever 18b which is in contact with this upper end also becomes the uppermost position. Therefore, as shown in the upper diagram of FIG. 7C, the rear end portion of the plunger position detection lever 18b is changed from a slightly inclined state to a larger inclined state (for example, the angle θ ₂ ). Since this angle θ ₂ is sufficiently larger than the angle θ _{1 at the} intermediate position (θ ₁ <θ ₂ ), the rear end portion of the rotary shaft 18c is in contact with the base surface of the terminal holding base 19c. The second contact terminal 19b is largely tilted in the direction of the arrow from the upright state by rotating about. As a result, as shown in the lower diagram of FIG. 7C, the normal switch 182 is operated by the second contact terminal 19b.
Can be switched.

Since the normal switch 182 is for switching between the normal operation operation and the frozen dessert extracting operation in the normal control, the normal switch 1 is switched by the above switching.
The state 82 changes from the state corresponding to the normal driving operation to the state corresponding to the frozen dessert extracting operation. Therefore, the control unit 20 determines that the user has requested to take out the frozen dessert, starts or continues the rotation of the stirring blade 13 in the cylinder 12, and the rotation of the stirring blade 13 causes the frozen dessert to pass through. It is pushed out from 17b toward the extraction pipe portion 17a. With this, the completed frozen dessert can be taken out. In addition,
At the uppermost position, of course, the safety switch 181 cannot be switched, so the safety control remains released.

As described above, according to the present invention, when the front lid is attached, the plunger position detecting lever protruding from the direction different from the attaching direction of the front lid is brought into contact with a part of the front lid. Therefore, the attachment of the front lid is once hindered by the plunger position detection lever.

Conventionally, even if the detection means for detecting the attachment of the front lid portion is provided, it is merely detected whether or not the front lid portion is attached. Therefore, no attention was paid to the installation of the front lid, which is important for ensuring the safety of the frozen dessert manufacturing device, before or during the installation of the front lid.

On the other hand, in the present invention, as described above,
Since the plunger position detection lever provided in the vicinity of the opening also serves as the detection means, the existence of the detection means becomes clear to the user. Therefore, the importance of the attachment of the front lid portion is recognized again for the user. As a result, for example, it is possible to more reliably avoid a situation in which the user unknowingly forms the same condition as when the front lid is attached, and the stirring blade 13 malfunctions.

Moreover, since the plunger position detecting lever takes the lowermost position, the front lid cannot be attached to the opening of the cylinder as it is.
Therefore, one action is added to the work of attaching the front lid portion, and the user can be given an opportunity to reconfirm the ensuring of safety by attaching the front lid portion.

Further, since the front lid portion is attached after the plunger position detecting lever is released from the contact, the user can always be aware that the safety mechanism is provided, and as a result, the front lid portion is attached. The user's attention can be directed to the installation work of.

Further, the position changing mechanism moves the plunger position detecting lever to the uppermost position (first position) and the intermediate position (second position) corresponding to at least the position of the plunger.
In addition to changing to the conventional position, the position of the plunger can be changed to the third position, which is a position where the front cover can be contacted near the opening when the front cover is attached. Has become.

In this structure, in the take-out switch mechanism interlocked with the rear end of the plunger position detection lever, the frozen dessert take-out operation is switched to the uppermost position and the normal operation operation is performed to the intermediate position, corresponding to the position of the plunger. At the lowest position, the operation is switched to a safe operation in which the operation of the stirring blade is prohibited, and the control unit executes the control corresponding to each operation.

Therefore, since the switching means for the normal control and the switching means for the safety control are integrated into one take-out switch mechanism, the device structure can be simplified and made compact. However, the above first to third
The position of is not limited to the above-mentioned uppermost / intermediate / lowermost positions, but may be changed depending on the position of the plunger, the position of the take-out switch mechanism, or the contact state of the plunger position detection lever. It is set.

In the present embodiment, the position of the front lid 16 at which the tip of the plunger position detection lever 18b abuts is particularly limited in the lowest position in order to prevent the front lid 16 from being attached. Instead of the above, for example, as shown in FIG. 9, it may be in the vicinity of the upper end portion of the plunger 17d in the front lid portion 16b.

In the front lid portion 16b shown in FIG. 9, the frame portion contacting the opening 12a is smaller than that of the front lid portion 16 described above.
7d directly contacts the tip of the plunger position detection lever 18b, and then the mounting is hindered.

That is, in the present embodiment, it is sufficient that it is possible to prevent the front cover from being attached while the plunger position detecting lever is at the lowest position, and the shape and opening of the front cover may be changed. There is no particular limitation on the method of attachment to the plunger, the shape of the plunger position detection lever, the state of the lowermost position, or the like.

[Second Embodiment] Another embodiment of the present invention will be described with reference to FIGS. 10 to 15.
It is as follows. The present invention is not limited to this. Further, for convenience of description, members having the same functions as those used in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the first embodiment, the frozen dessert take-out mechanism is provided with a take-out lever for manually moving the plunger up and down, that is, an example of a handle type frozen dessert making apparatus. An example of a frozen dessert manufacturing apparatus having a structure in which a takeout mechanism is not provided with a takeout lever and the plunger is moved up and down by another moving means will be described. For the sake of convenience of description, a frozen dessert manufacturing apparatus having no such take-out lever will be referred to as a "non-handle type".

Since the basic structure of the non-handle type frozen dessert manufacturing apparatus according to the present embodiment is the same as the structure described in the first embodiment with reference to FIG. 2, the description thereof will be omitted. When viewing the frozen dessert making device from the front,
As shown in FIG. 10, the front lid portion 26 (corresponding to the front lid portion 16) is not provided with a structure corresponding to the takeout lever 17e (see FIG. 2 and the like), and the takeout switch mechanism 18 is provided. Instead, the front lid 2
6 is different in that a contact lever 28b is provided so as to contact the upper portion of the frame portion 6 of FIG.

The plunger 17d provided on the front lid portion 26 and the take-out mechanism 17 including the same are substantially the same as those described in the first embodiment except that the take-out lever 17e is not provided. .

However, in this embodiment, the plunger 1
7d is automatically moved by an electronic control or the like by the operation of the operation switch (operation means) of the operation panel 30 shown in FIG. 10 (auto system), or by using a foot pedal (operation means) not shown. A configuration that moves mechanically (manual method) can be mentioned, but the invention is not particularly limited. That is, in the present embodiment, the take-out lever 1 is attached to the moving mechanism of the plunger 17d.
There is no particular limitation as long as it does not include 7e.

The contact lever 28b has, for example, a substantially straight rod shape, and is provided so as to be movable substantially vertically, for example. Since this contact lever 28b can function as a lid member attachment detecting means, the front lid portion (lid member) 26 is attached to the tip portion of the contact lever 28b as shown in FIG. In the state, it can come into contact with the upper portion of the frame portion of the front lid portion 26.
On the other hand, when the front lid portion 26 is removed,
As shown in FIG. 2, the tip end portion is lowered so as to be positioned lower than when the front lid portion 26 is attached.

That is, in the contact lever 28b according to the present embodiment, the attachment of the front lid portion 26 is detected when it is in contact with the front lid portion 26 shown in FIG. The position is a position (detection position) corresponding to the intermediate position in the first form. On the other hand, in the state in which the front lid portion 26 is removed as shown in FIG. 12, the tip end portion is lowered so as to prevent the attachment of the front lid portion 26, and thus corresponds to the lowest position in the first embodiment. It becomes the position (it makes it a descending position).

The contact lever 28b is shown in FIG.
As shown in FIG. 12 and FIG. 12, similarly to the first embodiment, the spring 28d urges the spring 28d downward so that the lower end position is the lowermost position. The contact terminal 28 is provided above the contact lever 28b.
a is provided, and the contact terminal 28a contacts the switch terminal 281 of the switch portion 28c provided near the contact lever 28b to switch the switch portion 28c.

Therefore, in the present embodiment, the contact lever 28b, the contact terminal 28a, the switch portion 28c, etc. form the front lid attachment detecting portion 28 which also functions as a safety device according to the present invention. .

In this embodiment, the take-out mechanism 17 is of a non-handle type, and a lever mechanism such as the take-out lever 17e is not used for moving the plunger 17d up and down. Therefore, unlike the plunger position detecting lever 18b in the first embodiment, the contact lever 28b is different.
The position of the tip of the is the detection position corresponding to the intermediate position,
It suffices to take two positions, a lowered position corresponding to the lowest position, and it is not necessary to take three positions.

Here, the configuration for detecting the attachment of the front lid portion 26 by simply taking only two positions is the conventional technique described above (the technique disclosed in Japanese Patent Laid-Open No. 10-136906).
At first glance it is similar to the configuration of the tact switch in
In the above conventional technology, the detection means such as the tact switch is
It is not provided so as to prevent the attachment of the front lid portion 26 or to clearly show the contact state to the user.

On the other hand, the contact lever 28b according to the present embodiment is similar to the plunger position detecting lever 18b according to the first embodiment, and the front lid portion 26 has the opening portion of the cylinder 12 when the fixed position is unchanged. It is in a lowered position where it cannot be attached to 12a. That is, when the front lid 26 is removed, the contact lever 2
The tip of 8b is always at a position that hinders the attachment of the front lid 26, so that the front lid 2 can be
One action for pushing up the contact lever 28b will be added to the attachment work of 6. As a result, there is surely an opportunity for the user to confirm the attachment of the front lid portion 26 again.

Further, since the front cover 26 is attached after pushing up the contact lever 28b, the user can always be aware that the safety mechanism is provided, and as a result, the front cover 26 can be secured. The user's attention can be directed to the installation work.

Incidentally, also in this embodiment, the front lid portion 2
At the time of attaching 6, the contact lever 28b has only to be capable of abutting the front end portion on the front lid portion 26, and does not necessarily obstruct the attachment of the front lid portion 26. In other words, although smooth mounting is possible without hindering the mounting of the front lid portion 26, it suffices that the contact state be clearly understood by the user at the time of mounting. This point will be described in detail in the third embodiment.

Next, regarding the control and operation of the safety device according to the present embodiment, regarding the change of the position of the contact lever 28b and the state switching operation of the front lid attachment detecting portion 28, the front lid portion 26 will be described. It will be described based on the mounting work of.

Lowered Position First, when the front lid 26 is attached to the opening 12a in the open state, the bolt 12 for attaching the front lid 26 provided in the opening 12a.
c (see FIG. 13 etc.), the positions of the holes formed in the front lid portion 26 are aligned, and then the front lid portion 2
6 is pushed toward the opening 12a (arrow E direction).

However, as shown in FIG. 13, when the front lid portion 26 is not attached, the contact lever 28b is moved to the fixed position, that is, the lowered position, by the biasing force of the spring 28d and the like (see FIG. 12). Therefore, the tip of the front lid 26 is located above the opening 12a.
It is located so as to prevent pushing in. Therefore, the front lid portion 26 is once prevented from being attached to the opening portion 12a by the tip portion.

That is, in the present embodiment, the contact lever 28
b functions as a projecting member, and if the front lid portion 26 is not attached, a lowering position that excessively protrudes until the tip portion reaches the attachment position of the front lid portion 26 (the position that covers the opening 12a). It is supposed to be taken.

In the front lid attachment detecting portion 28 in this state, as shown in FIG.
The contact terminal 28a provided at the rear end of the switch unit 28a descends in conjunction with the movement of the contact lever 28b.
The state is in contact with the switch terminal 281 of c.

Here, when the front lid portion 26 is attached, since it is a preparation stage for operating the frozen dessert manufacturing apparatus, it is basically in a state where normal control cannot be performed, as in the first embodiment. . However, there is a possibility that normal control can be performed due to accidental power-on or operation of an operation switch due to some erroneous operation.

On the other hand, when the tip of the contact lever 28b is in the lowered position, the switch portion 28c is switched to the safety operation. When it is determined that the stirring blade 13 is not attached, at least safety control for stopping the rotation of the stirring blade 13 is performed.

Since this safety control is prioritized over the normal control by, for example, the foot pedal or a specific operation switch, as in the first embodiment,
No normal control is performed and therefore the stirring blade 13 does not rotate.

Detecting Position When the front end of the contact lever 28b is in the lowered position as described above, the attachment of the front lid 26 is hindered. Therefore, in order to attach the front lid portion 26 to the opening portion 12a, the tip portion must be moved to a position higher than the detection position. Therefore, as shown in FIG. 14, the user pushes up the tip portion of the contact lever 28b with a finger or the like (in the direction of arrow D), and then opens the front lid portion 26 with the opening 12a.
Push it to the side (arrow E direction). As a result, the front lid portion 26 is securely attached to the opening 12a.

The front cover 26 attached to the opening 12a is completely fixed to the opening 12a by attaching the nut 12d to the bolt 12c, as shown in FIG. Further, when the contact lever 28b is released from the pushed-up state by the user, the tip end portion comes into contact with the upper portion of the frame portion of the front lid portion 26 and becomes the detection position.

At this detection position, the contact lever 28
Since b is moved upward from the fixed position (the lowered position), the front cover attachment detection unit 28, as shown in FIG. 11, has the switch terminal 281 of the switch unit 28c.
The contact terminal 28a, which was in contact with, moves upward with the movement of the contact lever 28b to release the contact. Therefore, the switch unit 28c is switched and the safety control is released. The control section 20 determines that the front cover section 26 is attached, and normal control is possible depending on whether the power is turned on or some operation switch is operated.

As described above, when the tip of the contact lever 28b is in the lowered position, the control of the control unit 20 is the safety control, while when it is in the detection position, the safety control is released and the normal control (normal operation operation is performed. And control of frozen dessert take-out operation).

Also in the present embodiment, the front cover 26 is once obstructed when the tip is in the lowered position. This is due to the detection means for detecting the front cover 26 attachment (in this case, This means that the contact lever 28b) is provided at a position that is “easy to understand” for the user. Moreover, one action is added to the work of attaching the front lid 26, such as pushing up the abutment lever 28b to release the abutment. Therefore, at the time of attaching the front lid 26, be careful of the attachment work to the user. Is aroused. As a result, the front lid portion 26 can be properly attached, and the frozen dessert manufacturing apparatus can be more efficiently prepared for operation.

Further, since the front cover 26 is attached after the contact lever 28b is released from contact, the user can always be aware that a safety mechanism for safe operation is provided. It is possible to guide the user's attention to the work of attaching the front lid portion 26.

Moreover, since the safety control is not released unless the front lid portion 26 is securely attached, the stirring blade 13 does not rotate carelessly, and the user's attention to safety is also aroused. It Therefore, as a result, for example, due to the user unintentionally forming the same condition as the state in which the front lid is attached, the stirring blade 13 is inadvertently rotated (malfunction) without the front lid 26 attached. ) Can be more surely avoided, and damage to the cylinder 12 and an injury accident can be more surely avoided.

The normal control relating to the frozen dessert taking-out operation is the same as in the case of corresponding to the uppermost position in the first embodiment, and is therefore the same as that of the conventionally known frozen dessert manufacturing apparatus. The description is omitted.

As described above, according to the present invention, when the front lid portion is attached, the contact lever is projected from the direction different from the attaching direction of the front lid portion with respect to the portion to which the front lid portion is attached. Therefore, the attachment of the front lid is once blocked by the contact lever.

Conventionally, even if the detection means for detecting the attachment of the front lid portion is provided, it is merely detected whether or not the front lid portion is attached. Therefore, no attention was paid to the installation of the front lid, which is important for ensuring the safety of the frozen dessert manufacturing device, before or during the installation of the front lid.

On the other hand, in the present invention, as described above,
A contact lever is provided in the vicinity of the opening, and the contact lever functions as a lid member attachment detection means. Therefore, the existence of the detection means becomes clear to the user, and the importance of the attachment of the front lid portion is recognized again for the user.

Moreover, since the contact lever is in the lowered position, the front lid cannot be attached to the opening of the cylinder as it is. Therefore, one action of pushing up the contact lever is added to the attachment work of the front lid portion, and as a result, the user can be given an opportunity to confirm the attachment of the front lid portion again. Also, since the front lid is attached after releasing the obstruction by the abutment lever, the user can always be aware that a safety mechanism is provided, and as a result, the front lid is attached to the work. Can guide the user's attention.

In the present embodiment, the specific configuration of the front lid attachment detecting section is not particularly limited. For example, although the contact lever is configured to project from above the front lid portion, it may be projected from the lateral direction or may be projected from below. That is, the longitudinal direction of the contact lever may be different from the mounting direction of the front lid portion. Further, the method of urging the contact lever, the method of switching the switch portion, and the shape of the contact lever are not limited.

[Third Embodiment] The following will describe still another embodiment of the present invention with reference to FIGS. 16 to 18. The present invention is not limited to this. Further, for convenience of description, members having the same functions as those used in the first or second embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the first or second embodiment, when the front lid is attached, the protruding member (plunger position detecting lever or contact lever) that protrudes from a direction different from the attaching direction of the front lid is attached to the front lid. For example, the projection member is used to temporarily prevent the attachment of the front lid portion from being abutted on the portion so as to be caught. On the other hand, in the present embodiment, although the projecting member projects from a direction different from the mounting direction and contacts the front lid portion, the mounting itself is not hindered. In other words, in the present embodiment, the front lid portion is in a state of clearly abutting so as to conform to it even if it is not obstructed by the protruding member.

Specifically, a structure is provided in which a portion of the protruding member that abuts on the front lid portion is inclined with respect to the traveling direction when mounting the front lid portion, that is, an inclined portion is provided on the protruding member and As an example, a configuration in which a part of the front lid portion abuts is given. The tilted state of the tilted portion is such that the front side of the front cover 16 when the front cover 16 is attached (that is, the opening 12a side) is on the lower side and the opposite side is on the upper side. .

For example, when the structure of the safety device according to the present embodiment is applied to the handle type frozen dessert manufacturing device according to the first embodiment, as shown in FIG. 16, the plunger position detecting lever 18b according to the first embodiment is used. Instead, a plunger position detecting lever 18e having a sharper bent end portion is provided.

In this case, the plunger position detecting lever 18
The front end portion of e is the side of the front lid 16 in the traveling direction when the front lid 16 is attached (that is, the opening 12a).
Side) is the lower side and the opposite side is the upper side.

In the first embodiment, the tip end of the plunger position detecting lever 18b comes into contact with the upper end of the plunger 17d almost entirely, so that the tip end is in an intermediate position. , Plunger 17d
It was a bent part that became almost horizontal corresponding to the upper end of the. On the other hand, in the present embodiment, the bending angle of the tip portion of the plunger position detection lever 18e is steeper. Therefore, in the intermediate position, the upper end portion of the plunger 17d abuts as in the first embodiment, but the abutting state is partial, and the tip portion itself is not horizontal. It is in an inclined state with the side upward.

The front cover 16 is brought into contact with the tip having such an inclined portion, and then the front cover 1 is
A force is applied to 6 to move the front lid portion 16 toward the mounting direction (arrow E direction in the drawing). Here, since the plunger position detection lever 18e is movable upward, as the front cover 16 is attached and moved, the tip portion gradually moves upward along the inclination of the inclined portion (in the direction of arrow D in the figure). ) Move to. As a result, the work of attaching the front lid portion 16 is not substantially hindered.

Similarly, the structure of the safety device according to the present embodiment can be applied to the non-handle type frozen dessert manufacturing device according to the second embodiment. In this case, for example, as shown in FIG. 17, instead of the substantially rod-shaped contact lever 28d, a contact lever 28e whose tip portion is a bent portion so as to form the inclined portion as described above is used. Can be mentioned.

Here, in the contact lever 28e,
Unlike the case of the plunger position detection lever 18e,
The direction of bending the tip portion is the above-mentioned traveling direction side (opening 12
a side). Of course, the contact lever 28e may be bent in the opposite direction (on the side of the front lid portion 26), but the contact lever 28e is the front lid portion 2a.
Since it projects from substantially above 6, there is an advantage that bending it in the traveling direction side can reduce the bending angle and facilitate processing.

Alternatively, as shown in FIG. 18, instead of the contact lever 28d, a contact lever 28f having a larger diameter is used, and the inclined portion as described above is provided with respect to the tip end of the contact lever 28f. You may chamfer on the side (the said rear side) which contacts the front cover part 26 so that it may be formed. That is, in the case of the non-handle type configuration of the second embodiment, when the contact lever 28e having a relatively small diameter is used like the contact lever 28d, the bent portion is formed at the tip of the contact lever 28e. On the other hand, when the contact lever 28f having a larger diameter than the contact lever 28d is used, the tip end of the contact lever 28f may be chamfered.

Here, since the shape of both the contact lever 28e and the contact lever 28f is a substantially linear rod shape, if it is a columnar shape having a substantially circular cross section, The contact levers 28e and 28f themselves are easily rotated. Therefore, there is a possibility that the contact levers 28e and 28f may rotate without moving upward in accordance with the mounting movement of the front lid portion 26. Therefore, it is very preferable that the contact levers 28e and 28f are provided with a rotation preventing mechanism for preventing the rotation thereof.

The specific structure of the rotation preventing mechanism is not particularly limited, and various conventionally known structures are preferably used. For example, although not shown, the contact lever 2
A configuration is possible in which a part of 8e / 28f is cut and a guide is provided at this part so as to move the contact levers 28e / 28f only in the vertical direction. Of course, if the contact levers 28e and 28f are shaped so as not to rotate, the above rotation preventing mechanism is not necessary.

Incidentally, the plunger position detecting lever 18
The bending angle of the tip portion of the contact lever 28e or the contact lever 28e is not particularly limited. That is, the front cover 16 or 26 is sufficiently abutted, and the front cover 16 or 26 is bent at an angle such that the plunger position detection lever 18e or the contact lever 28e moves along the inclined portion when the front cover 16 or 26 is attached. Just do it. Therefore, the bending angle is appropriately set according to the projecting direction of the plunger position detection lever 18e and the contact lever 28e and the shape of the front lid portion 16 or 26 that abuts against this.

Similarly, the chamfering angle of the contact lever 28f is not particularly limited, and the chamfering angle of the contact lever 28f at the side of the contact lever 28f that comes into contact with the front lid portion 26 (the rear side) is as described above. It suffices that the rear side is upward and the front side is downward, and the chamfer is formed at an angle such that the contact lever 28f moves along the inclination. Therefore, the chamfer angle is also appropriately set according to the protruding direction of the contact lever 28f and the shape of the front lid portion 26 that abuts against the chamfering angle, like the bending angle.

As described above, in the present embodiment, unlike the first or second embodiment, the projecting member (plunger position detection lever or contact lever) contacts the front lid portion, and the front member is not positioned when the position is reached. Although it protrudes to a position that obstructs the attachment of the lid, it actually moves according to the attachment movement of the front lid so as not to obstruct the attachment.

Therefore, during the mounting work of the user, attention is paid to the mounting of the front lid portion to improve the safety, and the front lid portion can be released even if the user does not release the contact of the protruding member with the front lid portion. Can be attached.

However, in order to more surely call the user's attention in the work of attaching the front lid portion, as in the first and second embodiments, the protruding member is once caught to attach the front lid portion. Is preferably prevented.

Further, in any of the safety devices of the first to third embodiments, by providing a separate display means, it is possible to inform the user that the front cover is not attached. Good.

The display means is not particularly limited as long as it can display at least the fact that the front cover is not attached to inform the user. For example, segment type display element that can display simple characters such as numbers and alphabets,
A liquid crystal display element capable of displaying more detailed character information or image information is preferably mentioned, or a light emitting diode or the like which merely blinks may be used.

An operation panel (for example, FIG.
0) such as the operation panel 30), the protruding member (plunger position detection lever or contact lever)
If it is not possible to detect the attachment of the front lid, the control unit controls the display unit to display the abbreviation or character information indicating that the front lid is not attached, or to turn off the light. The light emitting diode is turned on. As a result, it is possible to reliably inform the user that the front lid is not attached, and thus it is possible to further improve the safety of the frozen dessert manufacturing apparatus.
