Description

The present invention relates to a refrigerator, and in particular to a refrigerator having multiple storage compartments.

In a typical refrigerator, storage compartments such as a refrigerator compartment are formed inside the insulated box, and these storage compartments are cooled by a refrigeration cycle so that the temperature range is suitable for cooling and preserving the stored items. Each storage compartment is cooled by blowing air cooled by the refrigeration cycle, so that the refrigerator compartment and vegetable compartment are cooled to the refrigerator temperature range, and the freezer compartment is cooled to the freezing temperature range.

The refrigerator compartment and vegetable compartment, which are cooled to the refrigeration temperature range, and the freezer compartment, which is cooled to the freezing temperature range, are separated by a heat-insulating partition material containing urethane resin. On the other hand, since both the refrigerator compartment and the vegetable compartment are storage compartments in the refrigeration temperature range, a material with low heat insulation, such as a resin board, is used as the partition material separating the refrigerator compartment and the vegetable compartment. A refrigerator with such a configuration is described, for example, in Patent Document 1.

JP 2018-44746 A

However, the invention described in Patent Document 1 above leaves room for improvement in terms of the convenience of removing stored items such as food from the storage compartment.

For example, in the case of a vegetable compartment that is closed with a pull-out insulated door, the amount, type, freshness, etc. of the vegetables stored inside the vegetable compartment cannot be checked unless the insulated door is pulled forward together with the storage container. Furthermore, the vegetables stored in the vegetable compartment cannot be removed unless the insulated door is pulled forward together with the storage container.

The present invention was made in consideration of the above circumstances, and its purpose is to provide a refrigerator that allows a user to remove items stored in the lower storage compartment by opening the insulated door of the upper storage compartment and opening the sliding part.

The refrigerator of the present invention comprises a first storage chamber formed inside an insulated box, a second storage chamber formed inside the insulated box below the first storage chamber, a first insulated door that closes a front opening of the first storage chamber, a second insulated door that closes a front opening of the second storage chamber, and a partition that separates the first storage chamber from the second storage chamber, the partition having an opening and a sliding portion that closes the opening in a slidable state, and further comprising a fixing mechanism that fixes the position of the sliding portion when the sliding portion is pushed rearward, and a release mechanism that releases the fixing of the sliding portion by the fixing mechanism in conjunction with the closing operation of the first insulated door .

The refrigerator of the present invention comprises a first storage chamber formed inside an insulated box, a second storage chamber formed inside the insulated box below the first storage chamber, a first insulated door that closes a front opening of the first storage chamber, a second insulated door that closes a front opening of the second storage chamber, and a partition that separates the first storage chamber from the second storage chamber, the partition having an opening and a sliding portion that closes the opening in a slidable state, and further comprising a protruding mechanism that is in a protruding state when the sliding portion is in an open state and is in a non-protruding state when the sliding portion is in a closed state, and when the protruding mechanism is in the protruding state, the protruding mechanism prevents the first insulated door from closing .

According to the present invention, a refrigerator can be provided in which a user can remove items stored in a lower storage compartment by opening the insulated door of the upper storage compartment and opening the sliding portion.

A refrigerator 10 according to an embodiment of the present invention will be described in detail below with reference to the drawings. In the following description, the same components are generally given the same reference numerals, and repeated description will be omitted. Furthermore, in the following description, the top, bottom, front, back, left and right directions will be used as appropriate, but left and right refer to the left and right when the refrigerator 10 is viewed from the front. In addition, in this embodiment, a refrigerator 10 having storage compartments in the freezing temperature band and the refrigerating temperature band is exemplified, but the refrigerator 10 may have only a storage compartment in the freezing temperature band, or only a storage compartment in the refrigerating temperature band.

Figure 1 is a perspective view of a refrigerator 10 according to an embodiment of the present invention, seen from the front left side. The refrigerator 10 has an insulated box 11 and a storage compartment formed inside the insulated box 11. The storage compartments include a refrigerator compartment 12, which is a first storage compartment, a vegetable compartment 121, which is a second storage compartment, and a freezer compartment 13. The front opening of the refrigerator compartment 12 is closed by a rotating first insulated door, an insulated door 18. The front opening of the vegetable compartment 121 is closed by a drawer-type second insulated door, an insulated door 19. The front opening of the freezer compartment 13 is closed by drawer-type insulated doors 20 and 21.

Figure 2 is a side cross-sectional view of the refrigerator 10. Referring to Figure 2, the insulated box 11 is composed of an outer box 111 made of a steel plate bent into a predetermined shape, an inner box 112 made of a synthetic resin plate arranged on the inside and spaced apart from the outer box 111, and a heat insulating material 113 filled between the outer box 111 and the inner box 112.

The storage compartment inside the insulated box 11 is divided from above into a refrigerator compartment 12, a vegetable compartment 121, and a freezer compartment 13. The refrigerator compartment 12 is a storage compartment in the refrigerated temperature range for storing fresh foods and beverages. The vegetable compartment 121 is a storage compartment in the refrigerated temperature range for storing vegetables, fruits, etc. The temperature inside the vegetable compartment 121 may be set slightly higher than the temperature inside the refrigerator compartment 12. The freezer compartment 13 is a storage compartment in the freezer temperature range for storing frozen foods, ice, etc.

The partition section 24 separates the refrigerator compartment 12 from the vegetable compartment 121. The front part of the partition section 24 is opened in a generally rectangular shape to form an opening 25. The opening 25 is closed by a slide section 26 that can slide in the front-rear direction. The slide section 26 is made of a transparent plate member such as glass. The user can open the insulating door 18 without pulling the insulating door 19 forward, and view the stored items such as vegetables stored in the vegetable compartment 121 through the transparent slide section 26. The configuration of the slide section 26 will be described later with reference to FIG. 4 etc.

The vegetable compartment 121 contains a storage container 17. The storage container 17 is slidably arranged inside the inner box 112 so that it can be pulled out together with the insulated door 19.

The vegetable compartment 121 and the freezer compartment 13 are separated by an insulating partition wall 23 filled with an insulating material such as urethane.

A cooling chamber 115 is defined at the rear of the freezer chamber 13, and an evaporator 116 is housed in the cooling chamber 115. A blower 15 is disposed inside the cooling chamber 115 and above the evaporator 116. An air passage 118 is connected to the upper part of the cooling chamber 115. A machine chamber 14 is defined at the lower rear end of the insulated box 11, and a compressor 22 is disposed in the machine chamber 14. The evaporator 116 and the compressor 22 form a refrigeration cycle together with a condenser and an expansion means (not shown). The air cooled by the evaporator 116 in the cooling chamber 115 is blown into the air passage 118 by the blowing force of the rotating blower 15, and is further blown out to the refrigerator chamber 12 and the vegetable chamber 121. A part of the air cooled by the evaporator 116 is also blown into the freezer chamber 13 through an opening formed in front of the cooling chamber 115.

A defrost heater 117 is disposed inside the cooling chamber 115 and below the evaporator 116. The defrost heater 117 is a heater that generates heat when electricity is applied. When electricity is applied during the defrosting process, heat is generated and the frost on the evaporator 116 is melted by the generated heat. The defrost water generated by the defrosting reaches an evaporator dish (not shown) and evaporates by heat exchange with the high-temperature compressed refrigerant.

Figure 3 is a side cross-sectional view of the refrigerator 10 when the sliding portion 26 is in the open state. Here, the sliding portion 26 is slid rearward inside the partition 24 to set the opening 25 in an open state where it does not cover it. With the sliding portion 26 in the open state, the user can rotate and open the insulating door 18 without pulling the insulating door 19 forward, i.e., while keeping the vegetable compartment 121 in a closed state, slide the sliding portion 26 rearward, insert their hand into the vegetable compartment 121 through the opening 25, and remove stored items such as vegetables.

Figure 4 (A) is a perspective view showing the slide portion 26 and the guide portion 30, and Figure 4 (B) is a partially enlarged perspective view showing key parts of the slide portion 26.

Referring to FIG. 4(A), the sliding section 26 mainly includes a sliding frame section 31, a sliding transparent section 32, and rollers 34.

The sliding frame portion 31 is a frame material made of synthetic resin with an outer edge that is roughly rectangular.

The slide transparent part 32 is fitted into the central opening of the slide frame part 31 and is made of a glass plate or a reinforced plastic plate.

The wall portion 33 is a portion that protrudes in the left-right direction from the front portion of the sliding frame portion 31 in the form of a wall. When the user pushes the wall portion 33 backward, the sliding portion 26 slides backward.

The rollers 34 are rotatably attached to the four corners of the sliding frame portion 31.

The guide parts 30 are disposed on the left and right sides of the sliding part 26, and are incorporated into the partition part 24 described above. The inner surfaces of the guide parts 30 in the left-right direction are opened, and the rollers 34 are inserted into the inside of the guide parts 30 through these openings. The guide parts 30 are disposed so as to incline downward toward the front. In this manner, the sliding part 26 moves forward along the guide parts 30 due to its own weight, without any operation by the user. In other words, the sliding part 26 has a self-closing function.

The front part of the sliding frame 31 can be made of a material with a higher specific gravity than the other parts, for example, a metal such as stainless steel. In this way, the center of gravity of the sliding part 26 can be moved forward, facilitating the self-closing function described above.

Referring to FIG. 4(B), the engagement portion 35 is formed on the upper surface of the slide frame portion 31 near the front end and near the right end. The engagement portion 35 is a portion of the upper surface of the slide frame portion 31 that protrudes partially upward, and here has a generally cylindrical shape. The engagement portion 35 is a portion for fixing the position of the slide portion 26, and its function will be explained with reference to FIG. 7 etc.

Figure 5 (A) is a cross-sectional view showing the slide portion 26 etc. in the closed state, Figure 5 (B) is an enlarged cross-sectional view showing the spring 37 etc., and Figure 5 (C) is a perspective view showing the slide portion 26 etc.

Referring to FIG. 5(A), a guide portion 30 is housed inside the partition portion 24, and guides the movement of the slide portion 26 in the front-rear direction. In addition, a spring 37 and an abutment portion 36 are disposed at the rear end of the guide portion 30.

Referring to FIG. 5(B), spring 37 is a biasing part that biases contact part 36 forward, and is disposed between the rear surface of guide part 30 and contact part 36. Contact part 36 has a rear end connected to spring 37, and a tip part having a substantially semicircular shape. As described below, contact part 36 and spring 37 bias slide part 26 forward when slide part 26 transitions from a closed state to an open state.

Referring to FIG. 5(C), as described above, the opening 25 formed by opening the front part of the partition 24 in a substantially rectangular shape is closed by the slide part 26. In this way, it is possible to separate the refrigerator compartment 12 formed above the partition 24 from the vegetable compartment 121 formed below the partition 24.

Figure 6 (A) is a cross-sectional view showing the slide portion 26 etc. in the open state, Figure 6 (B) is an enlarged cross-sectional view showing the spring 37 etc., and Figure 6 (C) is a perspective view showing the slide portion 26 etc.

Referring to FIG. 6(A), when the user pushes the wall portion 33 formed at the front end of the sliding portion 26 backward, the sliding portion 26 slides backward inside the guide portion 30. As a result, the opening 25 is in an open state where it is not covered by the sliding portion 26.

Referring to FIG. 6B, in the open state, the rear end portion of the slide portion 26 pushes the abutment portion 36 rearward, and the spring 37 is compressed in the front-rear direction, biasing the slide portion 26 forward.

Referring to FIG. 6(C), when the sliding portion 26 slides toward the front end of the partition portion 24, the opening 25 is open and not covered by the sliding portion 26, and the refrigerator compartment 12 and the vegetable compartment 121 are in communication with each other through the opening 25. In addition, the user can remove food such as vegetables from the vegetable compartment 121 through the opening 25.

Figure 7(A) is a plan view showing the fixing mechanism 27 when the sliding portion 26 is in a closed state, Figure 7(B) is a plan view showing the fixing mechanism 27 when the sliding portion 26 transitions from a closed state to an open state, and Figure 7(C) is a plan view showing the fixing mechanism 27 when the sliding portion 26 is in an open state.

Referring to FIG. 7(A), a fixing mechanism 27 is disposed on the right side of the sliding portion 26. The fixing mechanism 27 has a function of fixing the position of the sliding portion 26 when the sliding portion 26 is pushed rearward. The fixing mechanism 27 has a lever 38 and an engagement portion 35. The fixing mechanism 27 fixes the position of the sliding portion 26 in the open state, and does not fix the position of the sliding portion 26 when transitioning from the open state to the closed state.

The configuration of the lever 38 that constitutes the fixing mechanism 27 will be described in detail with reference to Figure 7 (B).

The lever 38 is a generally rod-shaped member that extends in the front-rear direction and is made of synthetic resin. Approximately the center of the lever 38 is rotatably connected to the partition section 24, which is the main body side of the refrigerator 10, by the support section 39. In this way, the lever 38 can rotate clockwise and counterclockwise around the support section 39 as the center of rotation.

The rear end portion of the lever 38, on the right side, is an inclined portion 40 that slopes rightward toward the rear. As described below, the rear end surface of the lever 38 presents a substantially flat contact surface that contacts the engagement portion 35 of the slide portion 26. The front end portion of the lever 38 is formed with a contact portion 41 that protrudes upward in a substantially plate-like shape. Furthermore, a spring 42 is disposed between the front end portion of the lever 38 and the slide frame portion 31.

The spring 42 biases the front end of the lever 38 to the left. This creates a biasing force that tends to rotate the lever 38 counterclockwise. Therefore, the abutment portion 41 is biased to the left, and the rear portion of the lever 38 is biased to the right.

Furthermore, FIG. 7(B) shows the state in which the slide portion 26 transitions from the closed state to the open state. When the slide portion 26 is pushed backward, the engagement portion 35 formed at the front right end of the slide portion 26 also moves backward. At this time, the engagement portion 35 moves backward while being pressed by the inclined portion 40 of the lever 38 biased by the spring 42.

Referring to FIG. 7(C), when the slide portion 26 is pushed all the way in, the engagement portion 35 of the slide portion 26 is positioned rearward of the rear end of the lever 38. The rear side of the lever 38 is biased rightward by the spring 42. Therefore, the rear surface of the lever 38 is positioned forward of the engagement portion 35, and the rear surface of the lever 38 abuts against the engagement portion 35. In this way, the engagement portion 35 of the slide portion 26 is supported from the front by the lever 38, and the slide portion 26 is maintained in the open state.

Figure 8 (A) is a perspective view showing the lower structure of the insulated door 18, and Figure 8 (B) is a perspective view showing the structure of the abutment portion 41.

Referring to FIG. 8(A), a storage pocket 55 for storing, for example, plastic bottles is provided at the bottom end of the insulated door 18. The bottom surface of the storage pocket 55 is partially protruded downward to form the protrusions 43 and 45. As described below with reference to FIG. 10, the protrusion 43 is a portion that causes the sliding portion 26 to close as the insulated door 18 closes. As described below with reference to FIG. 12, the protrusion 45 is a portion that prevents the insulated door 18 from closing when the sliding portion 26 cannot close.

Referring to FIG. 8(B), the abutment portion 41 of the lever 38 shown in FIG. 7(B) etc. protrudes upward from an opening 44 that opens near the front end of the partition portion 24.

Figure 9 is a perspective view showing the relative configuration between the contact portion 41 on the refrigerator 10 body side and the protrusion portion 43 on the insulated door 18 side. When a user attempts to close the rotating insulated door 18, the protrusion portion 43 formed on the lower end of the insulated door 18 comes into contact with the contact portion 41 that constitutes the release mechanism 28 described below.

Figures 10(A), 10(B), 10(C) and 10(D) are top views showing the closing operation of the sliding portion 26 by the release mechanism 28 in conjunction with the closing operation of the insulating door 18.

Referring to FIG. 10(A), the release mechanism 28 is a mechanism that releases the fixing of the slide part 26 by the fixing mechanism 27 in association with the closing operation of the insulated door 18. The release mechanism 28 has the protrusion 43 shown in FIG. 9 and a lever 38. The configuration of the lever 38 is as described with reference to FIG. 7(B) etc. When the insulated door 18 is in the open state, the rear end surface of the lever 38 presses the engagement part 35 of the slide part 26, whereby the position of the slide part 26 is fixed at the rear and the opening 25 is not covered by the slide part 26.

Referring to FIG. 10(B), when the user closes the insulated door 18, the protrusion 43 provided on the bottom surface of the insulated door 18 pushes the abutment 41 provided on the front end of the lever 38 to the right. As described above, the lever 38 can rotate around the support portion 39. Therefore, when the abutment 41, which is the front end of the lever 38, is pushed to the right, the rear end of the lever 38 is swung to the left.

Referring to FIG. 10(C), when the rear end of the lever 38 is swung to the left, the engagement portion 35 of the lever 38 is positioned to the left of the slide frame portion 31 of the slide portion 26. In this way, the slide portion 26 is no longer supported from the front by the lever 38, and slides forward due to the self-closing function described above. At this time, the insulated door 18 closes the refrigerator compartment 12.

Referring to FIG. 10(D), the sliding portion 26 slides forward, thereby covering the opening 25. As described with reference to FIG. 4(A), the guide portion 30 that guides the sliding portion 26 is inclined downward toward the front. Also, as shown in FIG. 6(B), the sliding portion 26 in the closed state is biased forward by the spring 37. That is, the sliding portion 26 has a self-closing mechanism. Therefore, even if the user does not perform a closing operation of the sliding portion 26, when the user closes the insulating door 18, the sliding portion 26, which has lost support from the lever 38, moves forward by a self-closing action and blocks the opening 25.

Figures 11(A) and 11(B) are top views showing a state in which the closing operation of the insulating door 18 is blocked by a plastic bottle 46, and Figure 11(C) is a perspective view showing that state.

Referring to FIG. 11(A), when the sliding portion 26 is in the open state, the sliding portion 26 is disposed at the rear and the opening 25 is not covered by the sliding portion 26. When the user closes the insulated door 18 in this state, the release mechanism 28 shown in FIG. 10(B) is activated, and the sliding portion 26 moves forward.

Referring to FIG. 11(B), for example, if a user mistakenly places an obstacle such as a plastic bottle 46 in the vegetable compartment 121, the sliding portion 26 is blocked from closing midway. That is, the front edge of the sliding portion 26 comes into contact with the top of the plastic bottle 46, and the sliding portion 26 is unable to close the opening 25. Furthermore, if the insulated door 18 remains open for a certain period of time or longer, a warning sound is generated from a speaker or the like to notify the user that the insulated door 18 is open. In response to this warning, the user can remove the plastic bottle 46 and close the insulated door 18, causing the sliding portion 26 to close the opening 25.

Referring to FIG. 11(C), when the PET bottle 46 prevents the sliding portion 26 from moving forward and the closing operation of the sliding portion 26 is not completed, the protruding mechanism 29 protrudes from the upper surface of the front portion 52. The protrusion 45 protruding downward from the insulated door 18 abuts against the protrusion 45 of the insulated door 18, preventing the insulated door 18 from closing. This prevents the insulated door 18 from being closed while the sliding portion 26 remains open, i.e., while the refrigerator compartment 12 and the vegetable compartment 121 remain in communication through the opening 25. The specific configuration of the protruding mechanism 29 will be described later with reference to FIG. 12.

Figure 12 (A) is a cross-sectional view showing a situation in which the closing operation of the heat-insulating door 18 is blocked by the protruding mechanism 29 in the protruding state. Figure 12 (B) is a cross-sectional view showing a situation in which the closing operation of the heat-insulating door 18 is not blocked by the protruding mechanism 29 in the non-protruding state.

Referring to FIG. 12(A), the protruding mechanism 29 is in a protruding state when the sliding portion 26 is in an open state, and is in a non-protruding state when the sliding portion 26 is in a closed state. In addition, when the protruding mechanism 29 is in a protruding state, the protruding mechanism 29 prevents the insulating door 18 from closing.

Specifically, the protruding mechanism 29 has a protruding portion 47, a spring 48, and a rotating portion 49.

The protruding portion 47 is a rod-like or plate-like member that extends in the vertical direction, and its upper portion protrudes upward from a through hole 54 that opens into the upper surface of the front surface portion 52. A spring 48 is disposed below the protruding portion 47, and the spring 48 biases the protruding portion 47 upward.

The rotating part 49 is a generally plate-shaped member that is rotatably arranged, and its rear end is rotatably connected to the partition part 24, and its front end is engaged with the middle part of the protruding part 47. In addition, a generally box-shaped storage part 50 that can store the rotating part 49 is provided below the rotating part 49.

When the opening 25 is not closed by the sliding part 26, the sliding part 26 has not reached the front end of the movable area. Therefore, the rotating part 49 is not pressed down by the roller 34 of the sliding part 26. Therefore, the protruding part 47 biased by the spring 48 protrudes upward a long distance, and its upper end is in a protruding state in which it abuts against the protrusion 45 of the insulating door 18. Therefore, in this state, the closing operation of the insulating door 18 is prevented.

Referring to FIG. 12B, when the sliding portion 26 moves to the front end of the movable region to close the opening 25, the roller 34 arranged at the front end of the sliding portion 26 presses the rotating portion 49 downward. This causes the rotating portion 49 to rotate about the rotation center 51, and the engagement portion 53 is pulled downward. Accordingly, the protruding portion 47 descends against the biasing force of the spring 48. Therefore, the upper end of the protruding portion 47 is arranged below the lower end of the protruding portion 45 of the thermal insulation door 18, and the protruding portion 47 does not abut against the protruding portion 45. Therefore, the protruding mechanism 29 does not impede the closing operation of the thermal insulation door 18, and the user can close the thermal insulation door 18 smoothly.

The above-described embodiment provides the following major advantages:

According to the present invention, referring to FIG. 3, by opening the insulated door 18 and sliding the opening 25 rearward, stored items such as vegetables can be removed from the vegetable compartment 121 through the opening 25. Specifically, since the sliding portion 26 is formed in the partition portion 24, the insulated door 18 can be opened with the insulated door 19 closed, and the sliding portion 26 can be opened to remove stored items from the vegetable compartment 121. This improves user convenience.

Furthermore, referring to FIG. 7(C), by fixing the position of the pressed-in slide portion 26 with the fixing mechanism 27, it is possible to prevent the slide portion 26 from accidentally moving forward and blocking the opening 25.

Furthermore, referring to FIG. 10, by closing the insulating door 18, the fixing mechanism 27 releases the fixing of the sliding portion 26, and the sliding portion 26 can be semi-automatically brought into a closed state.

Furthermore, referring to FIG. 11, when the protruding mechanism 29 is in the protruding state, the protruding mechanism 29 prevents the insulated door 18 from closing, thereby preventing the insulated door 18 from closing with the sliding portion 26 in the open state, and preventing the refrigerator compartment 12 and the vegetable compartment 121, which have different cooling temperature ranges, from accidentally communicating with each other.

Furthermore, referring to FIG. 4(A), the guide portion 30 is inclined downward toward the front, so that the slide portion 26 can be automatically closed along the inclined guide portion 30.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and modifications can be made without departing from the scope of the present invention. In addition, the above-described embodiments can be combined with each other.
The following inventions can be understood from the above-described embodiments.
The refrigerator of the present invention includes a first storage chamber formed inside an insulated box, a second storage chamber formed inside the insulated box below the first storage chamber, a first insulated door for closing a front opening of the first storage chamber, a second insulated door for closing a front opening of the second storage chamber, and a partition for partitioning the first storage chamber and the second storage chamber, the partition having an opening and a slide part for closing the opening in a slidable state. Therefore, according to the refrigerator of the present invention, a user can take out the stored items stored in the second storage chamber by opening the first insulated door of the first storage chamber and opening the slide part. Specifically, since the slide part is formed in the partition, the user can open the first insulated door while keeping the second insulated door closed, and open the slide part to take out the stored items from the second storage chamber. Therefore, the convenience of the user can be improved.
The refrigerator of the present invention is also characterized by further comprising a fixing mechanism that fixes the position of the sliding part when the sliding part is pushed backward. Therefore, according to the refrigerator of the present invention, by fixing the position of the pushed-in sliding part with the fixing mechanism, it is possible to prevent the sliding part from accidentally moving forward and blocking the opening.
The refrigerator of the present invention is further characterized by including a release mechanism that releases the fixing of the sliding part by the fixing mechanism in association with a closing operation of the first insulated door. Therefore, according to the refrigerator of the present invention, by closing the first insulated door, the fixing of the sliding part by the fixing mechanism is released by the release mechanism, and the sliding part can be semi-automatically closed.
The refrigerator of the present invention further includes a protruding mechanism that is in a protruding state when the sliding portion is in an open state and in a non-protruding state when the sliding portion is in a closed state, and when the protruding mechanism is in the protruding state, the protruding mechanism prevents the first insulated door from closing. Therefore, according to the refrigerator of the present invention, when the protruding mechanism is in the protruding state, the protruding mechanism prevents the first insulated door from closing, so that the first insulated door can be prevented from closing with the sliding portion in an open state, and the first storage chamber and the second storage chamber, which have different cooling temperature zones, can be prevented from being inadvertently connected to each other.
The refrigerator of the present invention further includes a guide portion that guides the slide portion to be movable in the front-rear direction, and the guide portion is disposed so as to be inclined downward toward the front. Therefore, according to the refrigerator of the present invention, since the guide portion is inclined downward toward the front, the slide portion can be automatically closed along the inclined guide portion.
