Description

TECHNICAL FIELD The present invention relates to a structure for fixing a heat radiating pipe provided at the bottom of a refrigerator.

Generally, a refrigerator has a dew condensation-proof heat radiation pipe laid at the bottom of the refrigerator body so that dew condensation does not occur on the bottom part (see, for example, Patent Document 1).

FIG. 14 shows the refrigerator described in Patent Document 1. In this refrigerator, a heat radiation pipe 102 is laid on the bottom of a refrigerator body 101, and a handle 103 dedicated to carrying stairs is embedded in the bottom of the refrigerator body 101 in the front-back direction. It is engaged with the dowel 104 .

In this way, the refrigerator in which the heat radiation pipe 102 is laid at the bottom of the refrigerator body 101 can prevent the bottom surface of the refrigerator body 101 from being cooled due to the cold radiation from the storage compartment, and moisture in the atmosphere can be prevented from reaching the bottom surface of the refrigerator body 101. It is possible to prevent troubles such as dew condensation and dripping on the floor surface and wetting the floor surface.

JP 2016-44941 A

However, the front end portion of the heat radiating pipe 102, that is, the vicinity of the front opening of the storage compartment is not fixed and is in a free state. Due to fluctuations in the foaming pressure and flow of the foamed heat insulating material, as well as vibrations during assembly and transportation, the position may be displaced in the vertical direction or in the front-back direction. Then, it is fixed by the foamed heat insulating material while it is in the displaced state.

As a result, when the position of the heat radiating pipe 102 is shifted upward, the distance between the front end portion of the heat radiating pipe 102 and the bottom surface of the storage chamber is shortened, and the heat of the heat radiating pipe 102 is stored. It will affect the room, and the energy saving performance will decrease. In particular, the portion where the front end of the heat pipe 102 is located is near the opening of the storage compartment that is opened and closed by the door, and the temperature tends to rise due to the influence of the outside temperature. The thermal effect becomes large.

In addition, the distance between the front end portion of the heat radiating pipe 102 and the bottom surface of the refrigerator body 101 becomes large, and the heat insulation of the bottom surface of the refrigerator body 101 by the heat radiating pipe 102 becomes insufficient, resulting in a sufficient anti-condensation effect. disappear.

Therefore, the applicant attempted to fix the front portion of the heat radiating pipe 102 to the inner surface of the outer box of the refrigerator body 101 with tape in order to solve the above problem.

However, in the above-described configuration, a separate step of taping is required, which leads to an increase in cost. In addition, the tape may be peeled off due to variations in taping work, etc., and the heat dissipation pipe 102 may be displaced upward. There is still room for improvement in order to eliminate the variation in the energy-saving performance and dew-proof effect and to stabilize the performance.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to stabilize the energy-saving and anti-condensation effects of a refrigerator by ensuring the fixation of the front end portion of the heat radiating pipe.

A refrigerator according to the present invention includes a refrigerator main body having a storage compartment, and a heat radiation pipe laid on the bottom surface of the refrigerator main body. A stepped portion is provided by lowering the part to be held by one step, the pipe fixing portion is positioned on the stepped portion, the heat radiating pipe is fixed to the pipe fixing portion, and the stepped portion is provided in the direction away from the storage chamber .

With the configuration described above, the heat radiation pipe can be firmly and accurately fixed at a predetermined position, so that the refrigerator can have a stable energy-saving effect and anti-condensation effect.

A first invention comprises a refrigerator main body having a storage compartment, a handle member for transportation attached to the front bottom of the refrigerator main body, and a heat radiation pipe laid on the bottom surface of the refrigerator main body, wherein the pipe is connected to the handle member. A fixing portion is provided and the heat radiating pipe is fixed to the pipe fixing portion.

Accordingly, the front end portion of the heat radiating pipe can be securely fixed to the front bottom portion of the refrigerator body by using the handle member. Moreover, since the handle member is attached and fixed to the main body of the refrigerator, it does not move due to fluctuations in the foaming pressure of the foamed heat insulating material or vibrations during assembly and transportation, and the heat radiation pipe can be accurately fixed at a predetermined position. Therefore, the heat radiating pipe is not fixed in a displaced position, and the energy saving effect and the anti-condensation effect can be stabilized.

According to a second aspect of the present invention, in the first aspect, a stepped portion is provided on the bottom surface of the refrigerator body by lowering the portion facing the pipe fixing portion of the handle member by one step, and the pipe fixing portion of the handle member is attached to the stepped portion. The heat dissipating pipe is fixed by locating the provided pipe fixing claws.

As a result, it is possible to eliminate the adverse effects that tend to occur when fixing the heat radiating pipe using the handle member, and to stabilize the energy saving effect and the anti-condensation effect. That is, if the heat radiating pipe is fixed using the handle member, the heat radiating pipe will be closer to the storage chamber by the height dimension of the pipe fixing claws provided on the pipe fixing portion of the handle member, and the heat from the heat radiating pipe will be dissipated. The influence of the heat will increase and the energy saving performance will decrease.

Moreover, when pipes are fixed to the bottom surface of the refrigerator with pipe fixing claws, the pipe fixing claws may protrude from the bottom surface toward the floor surface and damage the floor during transportation.

However, if a stepped portion is provided by lowering the portion facing the pipe fixing portion on the bottom surface of the refrigerator body, the front end portion of the heat radiating pipe fixed to the pipe fixing claw is separated from the storage chamber by this stepped portion, and the heat is dissipated. It is possible to increase the heat insulating distance between the pipe and the storage compartment, thereby reducing the influence of the heat from the heat radiation pipe on the storage compartment and enhancing energy saving. That is, it is possible to stabilize the energy saving performance and the anti-condensation effect while enhancing the energy saving performance.

In a third invention, in the second invention, the handle member has a step similar to the shape of the bottom surface of the refrigerator main body, and a thick portion on the front side near the opening of the storage compartment is used as a screw fixing portion, A pipe fixing claw is provided on the lower pipe fixing portion opposite to the opening, and the thick screw fixing portion is screwed to the bottom surface of the refrigerator main body to attach and fix the handle member to the refrigerator main body.

As a result, the attachment of the handle member to the refrigerator body becomes strong, and the front end position of the heat radiating pipe can be accurately and firmly fixed at a predetermined position even if the foaming pressure of the foamed heat insulating material fluctuates or vibrations occur during assembly and transportation. be able to. Therefore, the energy-saving performance and anti-condensation effect can be made more stable, and a high-quality refrigerator can be obtained.

According to a fourth invention, in the first to third inventions, the handle member is provided with reinforcing ribs on at least the surface opposite to the lower pipe fixing portion provided with the pipe fixing claws.

As a result, the strength of the pipe fixing portion, which tends to be weakened by lowering it one step, can be increased, and the heat radiating pipe can be firmly fixed by the pipe fixing portion. As a result, the energy-saving and dew-proof effects can be stabilized, and the refrigerator can be of even higher quality.

The legs 21 can be installed horizontally by adjusting the left and right heights of the refrigerator main body 1, and the height can be adjusted using a tool such as a wrench, which will be described later.

For example, in this example, the leg portion 21 is constructed by screwing a leg 21b having a hexagonal portion with a bolt into a leg fitting 21a. It is not limited.

Further, a handle member 22 is provided on the front bottom portion of the refrigerator main body 1 separately from the leg portion 21 . This handle member 22 is used when the refrigerator main body 1 is transported in an upright state. It is attached and fixed to the

A decorative cover 23 is detachably attached to the front bottom portion of the refrigerator body 1 . The decorative cover 23 covers the leg portion 21 and the handle member 22 on the front side of the refrigerator body 1 to ensure safety and design.

Here, the radiating pipe 20 laid on the bottom of the refrigerator main body 1 is arranged in the left-right direction by engaging the handle 1a dedicated to stair-conveyance embedded in the bottom of the refrigerator main body 1 at the midpoint in the front-rear direction as in the prior art. The front end portion is fixed to the bottom of the refrigerator body 1, although it is locked so as not to be displaced.

The configuration will be described with reference to FIG. In FIG. 9, the refrigerator main body 1 has a stepped portion 24 formed by lowering the portion of the front bottom face facing the front end of the heat radiation pipe 20 by one step.

On the other hand, the handle member 22 is composed of a handle portion 25 and a main body fixing portion 26 located behind the handle portion 25. The main body fixing portion 26 behind the handle portion 25 has a stepped upper surface similar to the bottom surface of the refrigerator main body 1. There are steps.

Then, pipe fixing claws 28 having a pair of key-shaped projections are erected on the stepped portion 27 which is lowered by one step. and the outer casing 2, and the front end of the heat radiating pipe 20 is press-fitted into the key-like portion and fixed. In this state, a foamed heat insulating material 4 is filled between the inner box 3 and the outer box 2. - 特許庁

A reinforcing rib 27a is integrally formed on the lower surface of the pipe fixing portion 27 on which the pipe fixing claws 28 are provided to increase strength.

The front end portion of the heat radiation pipe 20 is fixed to the bottom of the refrigerator body 1 as described above. A screw fixing portion 30 is formed on the front side near the opening and is one step higher and has a thicker wall. It is attached and fixed to the

The handle member 22 has a hand insertion opening 32 between the handle portion 25 and the body fixing portion 26, and the hand insertion opening 32 is provided between the handle portion 25 and the rear surface of the decorative cover 23. A hand insertion portion 33 that bends forward from 32 in a substantially L shape is formed.

An arcuate bulging portion 34 projecting upward is provided at the front end portion of the hand insertion opening 32 of the handle portion 25 . Further, a recess 35 recessed in the rearward direction is formed in the wall surface on the rear side of the hand insertion opening 32 .

In the refrigerator of this embodiment, a leg height adjusting tool 36 is attached to the rear surface of the decorative cover 23 covering the leg portion 21 and the handle member 22, as shown in FIGS. .

The mounting structure of the tool 36 will be described below. A tool mounting portion 37 is provided on the rear surface of the decorative cover 23 covering the leg portion 21 and the handle member 22 as shown in FIG.

As shown in FIG. 11, the tool mounting portion 37 is composed of a first rib 37a to which one end side of the tool 36 is fitted and fixed, and a second rib 37b to which the other end side is fitted and fixed. A tool 36 can be mounted in the left-right space between them.

In the tool mounting portion 37, a part of the tool 36, in this example, the rear side of the wrench portion 36a where the width of the tool 36 in the front-rear direction is large, protrudes toward the refrigerator main body 1 as shown in FIG. It is configured to be mounted in such a manner as to overlap the bottom surface.

A cover portion 38 is integrally formed on the rear edge of the decorative cover 23 where the tool 36 is mounted. It is configured to cover a portion overlapping the refrigerator body 1. - 特許庁

In this example, as shown in FIGS. 10 and 11, the cover portion 38 is provided over substantially the entire length of the tool 36 in addition to the overlapping portion. It should be provided so as to cover only the

The tool 36 is bent in a substantially V-shape between the wrench portion 36a and the handle portion 36b, and the tool 36 is attached to the decorative cover 23 in the opposite direction to the normal state (upper and lower surfaces). A reverse mounting preventing portion 39 is provided to prevent the mounting of the battery in the opposite direction.

As shown in FIGS. 12 and 13, the reverse mounting prevention portion 39 abuts on the upper surface of the tool 36 when the tool 36 is set in the normal state, and when the upper and lower surfaces are set in the opposite direction, the reverse mounting prevention portion 39 is located below the upper surface of the tool 36, and the tool 36 cannot be locked by the first rib 37a and the second rib 37b. It may be a configuration.

Next, the operation and effects of the refrigerator configured as described above will be described.

In the refrigerator of this embodiment, a handle member 22 for transportation is attached to the front bottom portion of the refrigerator body 1, and a pipe fixing claw 28 is provided on the pipe fixing portion 27 of the handle member 22. A front end portion of a heat radiating pipe 20 laid on the bottom of the housing 1 is fixed. A handle member 22 for fixing the front end portion of the heat radiating pipe 20 is mechanically attached to the refrigerator main body 1 with screws 31. As shown in FIG.

Therefore, the front end portion of the heat radiating pipe 20 is not dislocated due to fluctuations in the foaming pressure of the foamed heat insulating material or vibrations during assembly and transportation, as in the case of tape attachment, and can be accurately fixed at a predetermined position. become. Therefore, it is possible to provide a refrigerator having stable energy-saving performance and anti-condensation effect. Moreover, since work such as tape application is not required, the pipe can be fixed at a low cost without causing an increase in cost due to an increase in the number of parts and an increase in the number of man-hours.

Here, in order to stabilize the energy-saving and dew-preventing effects without variation, if a pipe fixing claw 28 is provided on the pipe fixing portion 27 of the handle member 22 to fix the front end portion of the heat radiating pipe 20, The front end portion of the heat radiating pipe 20 is located near the bottom of the vegetable compartment 10 by the height h of the pipe fixing claw 28 projecting into the box 3 . As a result, the thermal effect of the heat radiation pipe 20 on the vegetable compartment 10 is increased, and the frequency of the cooling operation increases, resulting in a decrease in energy saving performance.

However, in the present embodiment, the bottom surface of the refrigerator main body where the front end portion of the heat radiating pipe 20 is fixed is lowered by one step to provide the main body stepped portion 24. The dimension to the bottom surface of the vegetable compartment 10, that is, the heat insulation distance is large. Therefore, it is possible to reduce the thermal influence of the heat radiation pipe 20 on the vegetable compartment 10, and to improve energy saving.

That is, by adopting the configuration of the present embodiment, not only can the energy saving performance and the anti-condensation effect be stabilized, but also the energy saving performance itself can be enhanced.

In the handle member 22 of the present embodiment, the main body fixing portion 26 has a step similar to the shape of the bottom surface of the refrigerator main body, and the screw fixing portion 30 on the front side near the opening of the vegetable compartment 10 is fixed with a screw 31. Therefore, it can be firmly attached and fixed to the bottom of the refrigerator main body 1.例文帳に追加

That is, the handle member 22 has a stepped shape, and the screw fixing portion 30 on the front side near the opening of the vegetable compartment 10 is one step higher and thicker. It can be firmly attached and fixed to the bottom of the main body 1 .

As a result, not only can the handle be able to withstand the weight of the refrigerator main body 1 having increased in weight, but also the front end position of the heat radiation pipe 20 can be firmly and accurately fixed at a predetermined position. This makes it possible to further stabilize the energy-saving performance and the anti-condensation effect.

In addition, since reinforcing ribs 27a are integrally formed on the lower surface of the pipe fixing portion 27 on which the pipe fixing claws 28 of the handle member 22 are provided, the pipe fixing portion 27 tends to be lowered and weakened in strength. The strength of the heat radiating pipe 20 itself is increased, and the fixing of the heat radiating pipe 20 by the pipe fixing claws 28 is made more robust, so that the energy conservation and the stabilization of the anti-condensation effect can be further enhanced.

Furthermore, the refrigerator of this embodiment also has the following effects.

That is, a decorative cover 23 is provided on the front bottom portion of the refrigerator body 1 to cover the handle portion 25 as well as the leg portion 21. The decorative cover 23 is provided with a tool mounting portion 37 on the rear surface thereof. is equipped with a tool 36 for adjusting the height of the leg portion 21. As shown in FIG.

Therefore, even if the refrigerator body 1 is large and heavy, the tool 36 can be used to easily adjust the height of the legs 21 .

Moreover, the tool 36 after adjusting the height of the leg portion 21 can be stored by attaching it to the back surface of the decorative cover 23, and loss can be prevented.

Furthermore, when the refrigerator body 1 is moved to another place and re-installed, the decorative cover 23 is removed, the tool 36 is taken out, and the height of the legs 21 can be easily adjusted.

Since the removal of the decorative cover 23 is always performed when adjusting the height of the leg portion 21, the presence of the tool 36 can be noticed by removing the decorative cover 23, and the tool 36 can be used without searching for it. .

Moreover, since the operation for removing the tool 36 is an essential operation that must be performed when adjusting the height, there is no troublesome operation for removing the tool separately.

Therefore, workability at the time of reinstallation is significantly improved.

Here, if the tool 36 is attached to the decorative cover 23 in order to improve the workability of adjusting the height of the leg portion 21, the width of the decorative cover 23 in the front-rear direction is increased, and the decorative cover 23 is not removed. The front end tends to protrude forward from the front surface of the vegetable compartment door 13 of the refrigerator main body 1, causing a problem.

That is, when the tool 36 is mounted on the decorative cover 23, and the tool 36 mounted on the decorative cover 23 has a large front-rear width, the wrench portion 36a has a large front-rear width. The longitudinal dimension of the decorative cover 23 is increased by the longitudinal width of the portion 36a. As a result, the front end of the decorative cover 23 tends to protrude from the front of the vegetable compartment door 13 of the refrigerator body 1 .

However, in the present embodiment, the tool mounting portion 37 provided on the decorative cover 23 is mounted such that the rear portion of the wrench portion 36a of the tool 36 protrudes toward the refrigerator body 1 and overlaps the bottom surface of the refrigerator body 1. Since it is possible, the width of the decorative cover 23 in the front-rear direction can be shortened by the amount of overlap.

Therefore, the front end of the decorative cover 23 can be positioned at the rear side so that the front end of the decorative cover 23 does not protrude from the front surface of the vegetable compartment door 13 of the refrigerator body 1, and the beauty and safety are enhanced. It can be a refrigerator.

Also, since the decorative cover 23 is provided with a cover portion 38 covering the wrench portion 36a of the tool 36 overlapping the refrigerator main body 1, dew condensation may occur on the bottom of the refrigerator main body 1 and may fall. Also, it is possible to prevent the condensed water from adhering to the tool 36. - 特許庁

Therefore, it is possible to prevent corrosion of the tool 36, which is often made of metal, and keep it in good condition for a long period of time.

Further, since the tool 36 is bent in a substantially V-shaped configuration, even if the height of the leg portion 21 is low, the handle portion 36b does not come into contact with the floor surface and interfere with the adjustment work. Height adjustment of the portion 21 can be easily performed.

In this case, since the tool 36 is bent in a substantially V-shape, if it is mounted in a state opposite to the normal state, a part of the tool 36, for example a part of the wrench part 36a in this case, will be on the floor side. There is a risk of it jumping out, contacting the floor and damaging the floor.

However, in the present embodiment, the decorative cover 23 is provided with the tool mounting portion 37 and the reverse attachment preventing portion 39 for preventing the tool 36 from being attached in the opposite direction, so that the tool 36 can be prevented from being attached in the opposite direction. .

Therefore, it is possible to prevent a part of the wrench portion 36a of the tool 36 from protruding downward and contacting the floor surface and damaging the floor surface.

Further, since the tool mounting portion 37 provided on the decorative cover 23 is positioned between the left and right handle members 22 provided on the refrigerator body 1, a space in the horizontal direction is created between the handle members 22 of the decorative cover 23. can be used to easily attach and store even a relatively long tool. At the same time, the front-rear width of the decorative cover 23 can be shortened. As a result, the front end of the decorative cover 23 can be prevented from protruding from the front surface of the vegetable compartment door 13 by preventing the decorative cover from becoming large.

Further, since the handle member 22 has a bulging portion 34 at the end portion of the handle portion 25 on the hand insertion opening side, the handle portion 25 is thickened by the bulging portion 34 and strength is improved. Even if the refrigerator body is heavy, it can withstand the load. By shortening the longitudinal length of the handle portion 25 compared to the conventional one, the width of the decorative cover 23 in the longitudinal direction can be shortened.

Therefore, the longitudinal dimension of the decorative cover 23 is reduced to the extent that the longitudinal dimension of the handle portion 25 is shortened so that the front end of the decorative cover 23 is located at the rear side, and the front end of the decorative cover 23 is located at the rear side, so that the vegetable compartment door 13 of the refrigerator main body 1 is positioned closer to the front side of the vegetable compartment door 13 . It can be made so that it does not protrude.

In addition, since the bulging portion 34 also serves as a hooking portion of the hand, it is possible to prevent the finger from slipping and unintentionally coming off the handle portion 25, thereby improving the safety during transportation. can be done.

Furthermore, since the grip member 22 has a recess 35 recessed in the rearward direction on the wall surface on the rear side of the hand insertion opening 32, the rear wall surface of the hand insertion opening 32 is increased by the amount of the recess 35 provided. and the bulging portion 34 of the handle portion 25 can be shifted rearward.

Therefore, the front-rear dimension of the handle member 22 can be shortened by the position of the hand insertion opening 32 shifted rearward. As a result, the size of the decorative cover 23 in the front-rear direction is also reduced so that the front end of the decorative cover 23 is positioned rearward so that it does not protrude from the front surface of the vegetable compartment door 13 of the refrigerator body 1.例文帳に追加

By preventing the front end of the decorative cover 23 from protruding from the front surface of the vegetable compartment door 13 as described above, the appearance and safety of the front bottom portion of the refrigerator body 1 can be improved.

As described above, the refrigerator according to the present invention has been described using the above embodiment, but the present invention is not limited to this. For example, in the present embodiment, the handle member 22 has been described as a separate member from the leg portion 21, but it may be an integral member with the leg portion 21, and the same effect can be obtained even in this manner. . That is, it should be considered that the embodiments disclosed this time are illustrative in all respects and not restrictive. In other words, the scope of the present invention is indicated by the scope of the claims rather than the above description, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims.

As described above, in the refrigerator of the present invention, the front end portion of the heat radiation pipe can be firmly fixed at a predetermined position, and the energy saving performance and condensation prevention effect can be stabilized without variation. Therefore, it can be widely applied to commercial refrigerators, automatic vending machines, and other freezer-refrigerated products as well as household refrigerators.
