[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal member and a seal structure of a container refrigeration apparatus using the seal member.

[0002]

2. Description of the Related Art FIG. 8 shows a main part of a conventional refrigeration system for a container having a general seal structure. In FIG. 8, reference numeral 61 denotes a container. A rectangular opening 62 is provided, and a refrigerating device 65 described below is mounted and fixed in the opening 62 in a fitted state, and the temperature inside the container 61 is adjusted by the refrigerating device 65. .

[0003] The refrigerating device 65 comprises a fixed frame 66 fastened and fixed to the front side of the opening 62, and a fixed frame 66.
And a main unit 67 provided with various devices constituting a refrigeration system such as an in-compartment fan 76 and an evaporator 77.

[0004] The refrigerating device 65 is mounted on the container 61 by being fitted into the opening 62 of the container 61 from the front side of the opening 62. In the mounted state of the refrigeration apparatus 65, first, the entire periphery of the main body 67 near the fixed frame 66 and the opening 6
To seal the outer peripheral gap W ₁ between the 2, as shown in FIGS. 8 and 9, unit seal 70 in the body portion 67 side is mounted over the entire circumference of the main body portion 67 I have.

On the other hand, in the refrigerating device 65, the air inside the container 50 sucked by the fan 76 disposed above the main body 67 is removed from the air inside the fan 76 disposed below the fan 76. The heat is exchanged in the vessel 77 to form temperature-controlled air, and the temperature-controlled air is blown laterally from an opening 79 formed in the side surface 67 a of the main body 67.
Further, in front of the side surface 67 a of the main body 67, a ventilation passage formed by a side ventilation passage forming member 78 (see FIG. 11) arranged vertically along the opening 62 of the container 61. (Not shown) is provided, and an opening (not shown) formed in the side ventilation passage forming member 78 and the opening 79 on the inside fan 76 side are closely opposed to each other. Then, the temperature-regulated air blown out from the opening 79 of the internal fan 76 enters the ventilation passage from the opening on the side ventilation passage forming member 78 side, flows down the ventilation passage, and flows down the container. It is designed to be blown out from the bottom side into the chamber 50. Therefore, the main body 6
7, a side gap W ₂ (see FIG. 11) between the inside fan 76 side of the upper part of the chamber 7 and the opening 79 of the side surface 67a is vertically sealed, and the temperature-controlled air is directly It is necessary to prevent it from being sucked into the fan 76 side,
To this end, a side seal 80 is disposed on the side surface 67a of the main body 67.

[0006]

However, the unit seal 70 and the side seal 80 have the following problems.

First, regarding the unit seal 70,
In this conventional unit seal 70, as shown in FIG. 9, the fixing portion 71 and the tongue portion 72 are both integrally formed of a soft resin material, and the fixing portion 71 is provided at a predetermined arrangement pitch in the longitudinal direction. Are fastened and fixed to the main body 67 side by the rivets 73, 73,. When the refrigerating device 65 is mounted on the opening 62 of the container 61, the tongue 72 of the unit seal 70 is appropriately bent and deformed by contact with the inner peripheral surface of the opening 62, and The device 65 is allowed to be mounted in the opening 62, and when the mounting is completed, the tip of the tongue 72 is moved by the elastic restoring force of the tongue 72.
A sealing property between the inner peripheral surface of the opening 62 and the outer peripheral surface of the main body 67 of the refrigerating device 65 is ensured.

However, this conventional unit seal 70
In the above, since both the fixing portion 71 and the tongue portion 72 are made of a soft resin material as described above,
When the rivet 73 is directly fixed to the main body 67 side by the rivet 73, the rivet hole portion of the fixing portion 71 gradually expands due to insufficient rigidity of the fixing portion 71, and the rivet 73 may come off from the fixing portion 71. was there. For this reason, conventionally, a stainless steel plate 74 is placed on the upper surface of the fixing portion 71, and the rivet 73 is
However, in the case of such a configuration, the number of parts is increased by the amount required for the corresponding plate 74, and the number of work steps is increased by the amount corresponding to the arrangement of the corresponding plate 74. There is a problem that the manufacturing cost of the device 65 is high.

On the other hand, as shown in FIGS. 10 and 11, the side seal 80 has a plurality of flat plate-shaped tongues 82, 82,. 81, which is connected to the main body 6 of the refrigerating device 65.
7, the one end 80a side of the side seal 80 is torn to the left and right, and the one end 80a side is directed forward in the mounting direction of the refrigeration system 65 and expanded in a substantially "eight-shaped" shape. With the rivets 73, 73,.
・ Tightened and fixed. With such a configuration,
When the refrigerating device 65 is fitted by being inserted into the opening 62 of the container 61, the tongues 82, 82,... Come into contact with the inner peripheral surface of the opening 62 and flex outwardly. The tongues 82, 82,.
The leading end of the contact member abuts against the inner peripheral surface of the opening 62 by its own elastic restoring force, and the required sealing property is secured.

However, like the unit seal 70, the side seal 80 also includes the fixing portion 81 and the tongue 8
2 are integrally formed of a soft resin material. Therefore, if the fixing portion 81 is directly fixed to the side surface 67a side of the main body 67 by the rivet 73, the fixing portion 81 is insufficient due to insufficient rigidity of the fixing portion 81. There is a possibility that the rivet hole portion gradually expands, and the rivet 73 is detached from the fixing portion 81. For this reason, conventionally, a stainless steel plate 74 is placed on the upper surface of the fixing portion 81, and the rivet 73 is attached via the plate 74. There is a problem that the number of components is increased by the amount required for the plate 74, and the number of work steps is increased by the arrangement of the plate 74. As a result, the manufacturing cost of the refrigeration system 65 is increased.

Further, conventionally, since the unit seal 70 and the side seal 80 are separately configured as described above, there is a problem that the cost increases due to an increase in the number of parts in stock. One of the measures to solve this problem is as follows. The unit seal 70 and the side seal 80 may be shared, but no specific proposal has been made yet.

Accordingly, the present invention is directed to a seal member and a container refrigeration using the seal member, which are capable of simultaneously achieving cost reduction by reducing the number of parts and the number of mounting operations, and cost reduction by sharing the seal member. The purpose is to propose a seal structure of the device.

[0019]

According to the present invention, the following effects can be obtained by adopting such a configuration.

According to the seal member of the first aspect of the present invention, the flat band-shaped fixing portion 46 and the curved band-shaped tongue 45 having a curved cross section are formed on one side in the longitudinal direction of both. In a sealing member formed by connecting the edges 46a and 45a to each other so as to have an acute L-shaped cross section, the fixing portion 46 is formed of a hard resin material, and the tongue portion 45 is formed of a hard resin material. Since the fixing portion 46 is made of a soft resin material and is integrally formed by extrusion molding, the fixing portion 46 has a high rigidity. Therefore, when attaching the sealing member, a conventional plate is used as in the related art. The fixing portion 46 can be directly attached to a required position by a rivet without any need. As a result, the corresponding plate is unnecessary, and the mounting work of the corresponding plate itself can be omitted, thereby reducing the number of work steps. As a synergistic effect of a potential, compared with the case of the sealing member integral structure by conventional soft resin material, in which the cost can be reduced.

The seal structure of the container refrigeration apparatus according to the second invention of the present application is provided with an opening 53 provided in the container 50.
In a sealing structure between the container 50 and the refrigeration apparatus 1 in a container refrigeration apparatus in which the refrigeration apparatus 1 is mounted and fixed in an inserted state from the outside of the container 50, A flat band plate-shaped fixing portion 46 made of a hard resin material and a curved band plate-shaped tongue having a curved cross section made of a soft resin material are provided around the entire periphery of the insertion portion 4 into the opening 53 of the container 50. And a sealing member 44 formed integrally by extrusion molding such that one side edge in the longitudinal direction of the two is continuous with each other so as to have an approximately L-shaped cross section at an acute angle. And tongue 4
5. One side edge portion 44 of the seal member 44 in which
a, a plurality of rivets 48 arranged at a predetermined pitch with respect to the insertion portion 4 with the fixing portion 46 disposed at a predetermined pitch with respect to the insertion portion 4. 48,...

Therefore, the fixing portion 46 of the sealing member 44 has high rigidity, and when the sealing member 44 is mounted, the fixing portion 46 is directly rivet-connected to the refrigerating device without using a contact plate as in the conventional case. 1 can be attached to the insertion portion 4 as a result, and as a result, the need for the corresponding plate is eliminated, and the mounting work of the corresponding plate itself can be omitted and the number of work steps can be reduced. The cost of the refrigerating apparatus can be reduced as compared with the case of a seal structure using a seal member having an integral structure made of a soft resin material.

Further, the sealing member 44 is inserted into the opening 53 of the container 50 in the refrigerating apparatus 1 at the insertion portion 4.
When the refrigeration apparatus 1 is fitted and inserted into the opening 53 of the container 50 in a state of being attached to the entire periphery of the container 50, the tongue 45 made of a soft resin material contacts the inner peripheral surface of the container 50. When the refrigerating device 1 is appropriately bent and deformed, the mounting of the refrigeration apparatus 1 on the container 50 is allowed, and the mounting operation is facilitated, while the mounting of the refrigeration apparatus 1 on the container 50 is completed. Since the tongue 45 abuts against the inner peripheral surface of the opening 53 by its own elastic restoring force, a high sealing performance is provided between the opening 53 of the container 50 and the fitting portion 4 of the refrigeration apparatus 1. Is guaranteed.

According to the seal structure of the container refrigeration apparatus according to the third aspect of the present invention, the following specific effects can be obtained in addition to the effects described above. That is, in the present invention, when the seal member 44 is attached to the refrigerating apparatus 1, the rear edge 46 b of the fixing portion 46 in the mounting direction is substantially attached to the fitting portion 4 of the refrigerating apparatus 1. The seal member 44 receives a force rearward in the mounting direction, for example, when the refrigeration apparatus 1 is mounted on the container 50 side, because the seal member 44 is closely opposed to the orthogonal surface 3. 48, 48,..., When the non-fastened portion located between them is moved rearward in the mounting direction, the edge of the fixed portion 46 on the rear side in the mounting direction before the amount of movement becomes excessive. 46b comes into contact with the surface 3 of the refrigerating apparatus 1 so that further retreat is restricted. Therefore, in the sealing member 44, the fastening and fixing portion by the rivets 48, 48,... And the non-fastening and fixing portion located between the rivets 48, 48,. The sealing member 44
As a result, a highly reliable sealing structure can be provided because high sealing performance can be obtained stably.

According to the seal structure of the container refrigeration apparatus according to the fourth aspect of the present invention, the following specific effects can be obtained in addition to the effects described above. That is, in the present invention, the arrangement pitch of the rivets 48 is set such that the arrangement pitch on the lower side of the entire periphery of the insertion portion 4 of the refrigerating apparatus 1 is smaller than the arrangement pitch on the other sides. Therefore, when the refrigerating apparatus 1 is mounted on the container 50, the lower side, which is most susceptible to a force in the mounting direction rearward due to interference with the opening 53 of the container 50, is arranged at a small pitch. The rivets 48, 48,... Reliably prevent the seal member 44 from being displaced rearward in the mounting direction, so that the seal member 44 achieves a highly reliable sealing property. By setting the arrangement pitch of the rivets 48 on the sides other than the lower side where the occurrence of the displacement of the seal member 44 toward the rear side of the mounting is small, In all sides if example in which can be reduced only manufacturing cost correspondingly arranged number of the rivet 48 is small in comparison with the case of setting a small arrangement pitch of the rivet 48.

The seal structure of the container refrigeration apparatus according to the fifth aspect of the present invention is a container refrigeration apparatus having an opening 53 provided in a container 50.
The refrigeration system 1 is fitted and fixed from the outside of the container 50 in an inserted state, and the temperature of air in the refrigerator sucked from the upper portion of the refrigeration system 1 is adjusted, and this is used as temperature-controlled air. 1 through the side air passage 32 formed by the air passage forming member 55 arranged near the opening 53 of the container 50 from the side surface 4b of the insertion portion 4 into the opening 53 in a state of being close to and facing the side surface 4b. In a container refrigeration apparatus that blows out to the bottom side of the container 50, a flat band plate made of a hard resin material is provided on the side surface 4b of the refrigeration apparatus 1 above a position where the temperature-regulated air is blown out. The fixing portion 46 and the tongue 45 in the form of a curved strip having a curved cross section made of a soft resin material are connected to one side edge 46a, 45a in the longitudinal direction of the two to each other to form an acute angle L. Character A sealing member 44 formed by integrally formed by extrusion as with, the seal member 44
The side edge 44a where the fixing portion 46 and the tongue 45 are continuous with each other is directed upward and is gradually inclined downward toward the front in the mounting direction of the refrigerating apparatus 1.

Therefore, the fixing portion 46 of the sealing member 44 has a high rigidity, and when the sealing member 44 is attached, the fixing portion 46 is directly rivet-connected to the refrigerating device without using a contact plate as in the prior art. It can be attached to one side surface 4b. As a result, as a synergistic effect between the elimination of the above-mentioned contact plate and the elimination of the work of mounting the plate itself and the reduction of the number of work steps, the use of the conventional seal member of an integral structure made of a soft resin material is used. The cost of the refrigerating apparatus can be reduced as compared with the case of the conventional seal structure.

When the refrigerating apparatus 1 is fitted and mounted in the opening 53 of the container 50 with the sealing member 44 attached to the side surface 4b of the refrigerating apparatus 1, the sealing member 44 The fixing part 46 and the tongue part 45
Are attached in such a manner that the continuous side edge 44a is directed upward and is gradually lowered and inclined toward the front in the mounting direction of the refrigerating apparatus 1, so that the tongue 45 is attached to the container during the mounting operation. The container 50 of the refrigeration apparatus 1 is bent downward by receiving a force of bending downward due to contact with the ventilation path forming member 55 on the side of the container 50.
On the other hand, when the refrigeration apparatus 1 is completely mounted on the container 50 side, the tongue 45 of the seal member 44 faces downward. While being bent and deformed, it comes into contact with the ventilation path forming member 55 by its own elastic restoring force, thereby ensuring good sealing performance. Particularly, in this case, the upper side of the seal member 44 is the suction side of the air in the refrigerator,
4 is a side on which the temperature-controlled air from the refrigerating apparatus 1 is blown, and the lower side of the seal member 44 is higher in pressure than the upper side. Since the tongue 45 of the 44 is bent downward, the tongue 45 is further pressed against the ventilation path forming member 55 by the differential pressure, and, for example, the tongue 45 is bent upward. Tongue 4
5 further ensures the sealing performance.

Further, as a combined effect of the second and fifth aspects of the present invention, the seal member 44 of the second aspect of the invention and the seal member 44 of the fifth aspect of the present invention have the same structure. The sealing member can be shared between different sealing portions, and the cost reduction of the refrigeration apparatus 1 is further promoted by the reduction in the number of stocked sealing members.

The lower end thereof communicates with the bottom ventilation passage 57 on the lower surface side of the buffer plate 56.

In FIG. 3, reference numeral 16 denotes a ventilation port, 1
Reference numeral 7 denotes an inspection window.

The refrigerating apparatus 1 configured as described above is
The main body 4 is mounted on the container 50 side in a state where the main body 4 is inserted into the inside of the container 50 through the opening 53,
In addition, the fixed frame 3 of the casing 2 is

Incidentally, the refrigeration system 1 for such a container
In order to maintain good refrigeration performance, it is necessary to prevent the outside air from entering the inside of the refrigerator or to prevent the inside air from leaking to the outside, and to blow out from the opening 27 to the side ventilation passage 32 side. it is necessary that the temperature control air a ₂ that is directly preventing so-called "short-circuit phenomenon" sucked into the cabinet the fan 6 side. In order to respond to such a demand, in this embodiment, a unit seal 41 described below is provided on the entire periphery of the main body 4 of the refrigerating apparatus 1 near the fixed frame 3 and a side seal of the main body 4 is provided. A side seal 42 described below is attached to a position directly above the opening 27. In this embodiment, the unit seal 41 and the side seal 4
2 is constituted by the seal member 44 having the same configuration, thereby realizing the common use of the seal member. Hereinafter, the configuration of the seal member 44 and a specific structure when the seal member 44 is used as the unit seal 41 and the side seal 42 will be described.

The structure above the sealing member 44 of the sealing member 44, as shown in FIG. 4, a fixing portion 46 of the flat strip strip, and a tongue portion 45 of the curved strip strip, one side edge 45a, respectively , 46a have a substantially “L” -shaped cross section in which they are connected to each other with an acute angle.
This basic form is not much different from a conventional general seal member.
However, the main feature of the sealing member 44 is that the tongue 45 of the tongue 45 and the fixing portion 46 is made of a soft resin material, and the fixing portion 46 is made of a hard resin material. And they are integrally formed by extrusion molding of a resin. The fixing portion 46 is formed with rivet holes 47, 47,... At appropriate intervals. Thus, the sealing member 44 is formed of a fixing portion 46 made of a hard resin material and a tongue portion 45 made of a soft resin material. The fixed portion 46 has high rigidity due to the integral structure with the tongue portion 4.
No. 5 has moderate flexibility. As described above, the seal member 44 has different characteristics between the tongue portion 45 and the fixing portion 46, so that the seal member 44 is connected to the unit seal 41 and the side seal 42 as described below.
In this case, the reduction of the manufacturing cost of the entire refrigeration system 1 and the securing of good sealing performance are compatible. Hereinafter, the structure and the like in the case where the seal member 44 is applied as the unit seal 41 and the side seal 42 will be described.

The case where the seal member 44 is applied as the unit seal 41, such as the structure of the unit seal 41, will be described by taking the upper surface 4a of the main body 4 as an example as shown in FIG.

The seal member 44 is replaced with the unit seal 41.
In this case, the fixing portion 46 is made of a hard resin material and has high rigidity. For example, the rivet 48 is formed by deformation of the fixing portion 46 like a conventional sealing member made of a soft resin material. Therefore, as shown in FIG. 5, the fixing portion 46 is directly placed on the upper surface 4a of the main body portion 4 and is mounted on the rivet 4 as shown in FIG.
8 enables fastening and fixing. Therefore, it is not necessary to prepare a stainless steel plate as in the conventional case, and since the man-hour for mounting the plate is not necessary, compared with the case where a seal member having an integral structure made of a soft resin material as in the past is used. Thus, the manufacturing cost of the refrigerating apparatus 1 can be reduced.

Further, with the unit seal 41 made of the sealing member 44 attached to the entire periphery of the main body 4 of the refrigeration apparatus 1, the refrigeration apparatus 1 is inserted into the opening 53 of the container 50 and mounted. In the case of mounting, the tongue portion 45 made of a soft resin material is appropriately bent and deformed by contact with the inner peripheral surface of the container 50, so that the refrigeration apparatus 1 can be mounted on the container 50. On the other hand, when the mounting operation of the refrigeration apparatus 1 to the container 50 is completed, the tongue portion 45 abuts on the inner peripheral surface of the opening 53 by its own elastic restoring force. 5
High sealing performance is ensured between the opening 53 of the zero and the fitting portion 4 of the refrigerating apparatus 1.

Further, as shown in FIG. 5, when the unit seal 41 is attached to the refrigerating apparatus 1, the edge 46b of the fixing portion 46 on the rear side in the mounting direction is
When the refrigerating apparatus 1 is closely opposed to the rear surface of the fixed frame portion 3 located in front of the main body 4, the unit seal 41 is installed, for example, when the refrigerating apparatus 1 is mounted on the container 50 side. Is subjected to a force rearward in the mounting direction, and in particular, when the unfastened portion located between the rivets 48, 48,... Is moved rearward in the mounting direction, the amount of movement becomes excessive. Previously, the edge portion 46b of the fixed portion 46 on the rear side in the mounting direction was
Abuts on the surface 3 to restrict further retreating movement. Therefore, in the unit seal 41, the fastening and fixing portion by the rivets 48, 48,... And the non-fastening and fixing portion located between the rivets 48, 48,. The unit seal 41 is provided with a high sealing property and can be stably obtained, so that a more reliable sealing structure can be provided.
When the mounting position of the rivet 48 is restricted, the width of the fixing portion 46 is increased, and
The space between the edge 46b on the rear side in the mounting direction of the frame 6 and the fixed frame 3 may be ensured.

Further, in the present embodiment, the arrangement pitch of the rivets 48 for fixing the unit seals 41 arranged on the entire periphery of the fixing portion 46 is changed by the fixing portion 4.
6, the container 50 of the refrigeration system 1
When the unit seal 41 interferes with the opening 53 of the container 50 at the time of the work of mounting on the container 50, the arrangement pitch at the portion where the rearward direction of the mounting direction is most likely to be applied is less likely to cause such interference. It is set to be smaller than the arrangement pitch on the side. According to such a setting, it is possible to reliably prevent the unit seal 41 from shifting rearward in the mounting direction during the mounting operation of the refrigeration apparatus 1, thereby realizing a highly reliable sealing property by the unit seal 41. Is done.

As shown in FIGS. 6 and 7, the structure of the side seal 42,
As with the unit seal 41, the seal member 44
It consists of. When the side seal 42 is attached, the side edge 44a where the fixing portion 46 and the tongue 45 of the seal member 44 are continuous is directed upward and the refrigeration apparatus 1 is mounted forward in the mounting direction. It is arranged in a state where it is gradually lowered.

According to the side seal 42, the fixing portion 46 has high rigidity. When the side seal 42 is mounted, the fixing portion 46 is directly rivet-freed by using rivets without using a conventional plate. It can be attached to the side surface 4b of the device 1. As a result, as a synergistic effect between the elimination of the above-mentioned contact plate and the elimination of the work of mounting the plate itself and the reduction of the number of work steps, the use of the conventional seal member of an integral structure made of a soft resin material is used. The cost of the refrigerating apparatus 1 can be reduced as compared with the case of the conventional seal structure.

When the refrigerating apparatus 1 is inserted into the opening 53 of the container 50 while the side seal 42 is attached to the side surface 4b of the refrigerating apparatus 1, the tongue is required during the mounting operation. The portion 45 receives the force of bending and deforming downward due to the contact with the ventilation path forming member 55 on the container 50 side, and flexes and deforms downward, and the refrigeration apparatus 1
In the state where the refrigeration system 1 is completely mounted on the container 50 side, the tongue portion 45 faces downward. While being bent and deformed, it comes into contact with the ventilation path forming member 55 by its own elastic restoring force, thereby ensuring good sealing performance. In particular, in this case, the upper side of the side seal 42 is the suction side of the air in the refrigerator, and the lower side of the side seal 42 is the side of the outlet of the temperature-regulated air from the refrigerating apparatus 1. Since the lower side of the seal 42 is higher in pressure than the upper side, the tongue 45 of the side seal 42 is bent downward in such a pressure state, so that the tongue 45 The state is further pressed by the pressure toward the ventilation path forming member 55 side,
For example, as compared with the case where the tongue 45 is bent upward, the sealing performance of the tongue 45 is further ensured.
