A more detailed structure of the mounting structure 20 will be described later.

  In FIG. 4 and FIG. 5, not the interior 21 side of the refrigerator 1 but the back surface portion 11 side of the refrigerator 1 is shown. FIG. 4 shows a state in which the deodorizing unit 30 is detachably attached by the attachment structure unit 20. However, FIG. 5 shows a state where the normal deodorizing agent 70 is attached to the attachment structure portion 20 instead of the deodorizing unit 30.

  As shown in FIGS. 4 and 5, the cool air path 12 is formed by the air path forming plates 14 </ b> A, 14 </ b> B, 14 </ b> C, 14 </ b> D and the frame portion 11 </ b> A of the back surface portion 11. The air path forming plate 14A is formed along the Z direction (up and down direction), and the air path forming plate 14B is formed along the X direction (left and right direction). Each of the air passage forming plates 14A and 14B has a plurality of holes 14E through which cold air passes. The air passage forming plates 14C and 14D are formed between the air passage forming plate 14A and the attachment structure portion 20 at intervals along the X direction.

The housing 33 has, for example, a rectangular parallelepiped shape, and includes substrates 33M and 33N through which cool air can pass.

  A photocatalyst 34 is disposed in the space between the substrates 33M and 33N. The substrates 33M and 33N have an upper surface portion 33D, a bottom surface portion 33C, and side surface portions 33F and 33G. The upper surface portion 33 </ b> D is a surface having optical transparency that allows visible light to pass therethrough. However, the bottom surface portion 33C and the two side surface portions 33F and 33G are opaque surfaces that do not transmit visible light. Thereby, the light L of the deodorizing unit 30 having the light emitting means 36 is scattered light, and this light L passes through the photocatalyst 34 to excite the photocatalyst 34 and is guided to the reflecting portion 32 side through the upper surface portion 33D. Be able to.

  As shown in FIGS. 4 and 6, the substrate 33 </ b> M has an opening 35 for passing the cold air W through the photocatalyst 34.

The light emitting means 36 is configured to emit light and diffuse and irradiate the entire photocatalyst 34. Although not shown, the light emitting means 36 is electrically connected to the control circuit board.

  As the light emitting means 36, for example, a light emitting diode (LED) that generates blue visible light can be employed. The photocatalyst 34 is excited by the energy of the light L generated by the light emitting means 36 to have photocatalytic activity, thereby deodorizing the cold air W passing through the photocatalyst 36 by a strong oxidation reaction and lysis action of the generated OH radical. Therefore, sterilization is performed.

  The reflecting portion 32 shown in FIG. 4 is a reflecting plate that can reflect visible light, such as an aluminum vapor deposition plate. As shown in FIG. 3, the light L that passes through the photocatalyst 36 passes through the light-transmitting upper surface portion 33 </ b> D, and is reflected by the reflecting portion 32 while changing the direction by 90 degrees.

It can be detachably held as if it is pressed. When the deodorizing unit 30 is attached or removed, the deodorizing unit 30 can be easily attached or removed by bending the first supporting member 42A and the second supporting member 42B by being slightly elastically deformed, and the deodorizing unit 30 is detached. Absent.

  By the way, as shown in FIG. 5, another attachment portion 47 can be positioned below the first attachment portion 41. This attachment portion 47 is not shown in FIG. The attachment portion 47 can be positioned below the lower end portions 44M and 45M at the left and right positions and the lower end portion 46M at the upper position. As will be described later, the attachment portion 47 is formed on an opaque lid member 80 (see FIG. 10) for covering the opening 13.

  As shown in FIG. 5, the attachment portion 47 is disposed to face the upper position of the third support member 42 </ b> C with an interval therebetween. The attachment portion 47 and the third support member 42C are provided to detachably hold the upper end portion 71 and the lower end portion 72 of the deodorizer 70 shown in FIG. The third support member 42 </ b> C is configured to hold the lower end portion 72 of the deodorizer 70 so as to be resiliently pressed toward the attachment portion 47 in the Z <b> 1 direction (upward direction).

  When attaching or removing the deodorizer 70, the deodorizer 70 can be easily attached and detached by bending the third support member 42C by elastic deformation. The structure of the deodorizing agent 70 is a member having a rectangular parallelepiped shape different from the structure of the deodorizing unit 30 and has activated carbon so that it can be deodorized by passing the cold air W.

  As shown in FIG. 4, the thickness of the deodorizer 70 in the X direction is smaller than the thickness of the deodorizer unit 30 in the X direction, but the length of the deodorizer 70 in the Z direction is the length of the deodorizer unit 30 in the Z direction. Longer than that.

  Reference is now made to FIG.

  FIG. 6 shows an example of a part including the cold air path 12 on the refrigerator compartment 5 side shown in FIG. 5, the attachment structure 20, and the attachment structure 20. 7 is a cross-sectional view taken along line AA of the attachment structure 20 and the attachment structure 20 in FIG. FIG. 8 is a perspective view showing a light-transmissive covering member 60 attached to the opening 13. As illustrated in FIG. 6, the cold air passage 12 and the attachment structure 20 can be configured as one member together with the other portion 100.

  As shown in FIG. 7, the reflecting portion 32 is detachably mounted on the inner surface side of the inclined portion 46 of the first mounting portion 41. The lower end portions 44M and 45M at the left and right positions and the lower end portion 46M at the upper position hold the upper end portion 30T of the deodorizing unit 30 shown in FIG. 4, and the first support member 42A and the second support member 42B of the second attachment portion 42 are The lower end portion 30H of the deodorizing unit 30 is held.

  The light-transmitting covering member 60 shown in FIG. 8 is a substantially rectangular plate member and can transmit light L. The light-transmitting covering member 60 has a claw portion 61 at the upper end portion and a claw portion 62 at the lower end portion. As shown in FIG. 7, the claw portion 61 of the light transmissive covering member 60 is fitted into the insertion hole 63 of the back surface portion 11, and the claw portion 62 of the light transmissive covering member 60 is inserted into the protruding portion 64 of the back surface portion 11. The covering member 60 can be detachably attached to cover the opening 13. FIG. 6 shows a state in which the deodorizing unit 30 is mounted on the cool air path 12.

  As shown in FIG. 7, the length SZ1 of the reflection part 32 when the reflection part 32 is viewed from the arrow LK direction is compared with the length SZ2 of the deodorization unit 30 when the deodorization unit 30 is viewed from the arrow LK direction (forward direction). It is set large. Thereby, even if it is limited space, since the reflective area of the reflection part 32 can be taken large, it can ensure more light quantity of the reflected light of visible light in the deodorizing unit which can be irradiated in a store | warehouse | chamber.

  On the other hand, FIG. 9 shows an example of a part including the cold air path 12 on the refrigerator compartment 5 side, the deodorizing agent 70, and the mounting structure 20 shown in FIG. 5. FIG. 10 is a cross-sectional view taken along line BB of the deodorizer 70 and the mounting structure 20 in FIG. FIG. 11 is a perspective view showing an opaque lid member 80 attached to the opening 13. FIG. 9 shows a state in which the deodorizing agent 70 is attached to the cool air path 12.

  An opaque lid member 80 shown in FIG. 11 is a substantially rectangular plate member, and is made of a plastic that does not transmit light. The lid member 80 has a claw portion 81 at the upper end portion, a claw portion 82 at the lower end portion, and another attachment portion 47 already shown in FIG. As shown in FIG. 10, the covering member 60 covers the opening 13 by fitting the claw portion 81 into the insertion hole 63 of the back surface portion 11 and hooking the claw portion 82 on the projection portion 64 of the back surface portion 11. The opening 13 is made of a plastic that does not transmit light. In addition, as shown in FIG. 10, in the state where the cover member 80 covers the opening portion 13, the mounting portion 47 is a lower portion of the lower end portions 44 </ b> M and 45 </ b> M and the lower end portion 46 </ b> M and protrudes to a position near the back surface portion 11. Yes.

  Thereby, according to the specification of the refrigerator 1, the attachment part 47 and the 3rd support member 42C can attach or detach the upper end part 71 and the lower end part 72 of the deodorizing agent 70 instead of attaching the deodorizing unit 30 shown in FIG. Can be retained.

  Next, an example of assembly work at the time of manufacture in the refrigerator 1 having the above-described structure will be described.

  As shown in FIGS. 3 and 7, at the site where the refrigerator 1 is assembled, the reflecting portion 32 is detachably mounted on the inner surface side of the inclined portion 46 of the first mounting portion 41. The lower end portions 44M and 45M and the lower end portion 46M of the left and right positions of the first attachment portion 41 hold the upper end portion 30T of the deodorizing unit 30 shown in FIG. 4 and the first support member 42A and the second support of the second attachment portion 42. The member 42B holds the lower end 30H of the deodorizing unit 30. In this case, the first support member 42A and the second support member 42B are elastically pushed downward to lower the deodorizing unit 30 with the lower end portions 44M and 45M, the lower end portion 46M, the first support member 42A and the second support. It can be easily held by being sandwiched between the members 42B. The light transmissive covering member 60 covers the opening 13. The light emitting means 30 in FIG. 4 generates light.

  As shown in FIG. 4, the cold air W passes through the hole 14E of the air passage forming plate 14A of the cold air air passage 12, passes between the air passage forming plates 14C and 14D, and passes through the photocatalyst 36 of the deodorizing unit 30. Later, it goes down, passes through the hole 14E of the air passage forming plate 14B, and proceeds to the vegetable compartment. As described above, when the cold air W passes through the photocatalyst 34 of the deodorizing unit 30, the photocatalyst 34 is excited by the energy of light generated by the light emitting means 36 to have photocatalytic activity, thereby strongly oxidizing the generated OH radicals. The cold air W passing through the photocatalyst 36 is deodorized and sterilized by the reaction and lysis.

  As shown in FIG. 3, the light L from the deodorizing unit 30 is reflected by the reflecting portion 32 and reaches the interior 21 side through the light-transmitting lid member 60 of the opening portion 13. Thereby, the light L reflected by the reflection part 32 can illuminate the inside 21 of the refrigerator 1. Moreover, when the user of the refrigerator 1 sees the light L that is reflected when the interior 21 is viewed, the cold air W in the refrigerator compartment 5 is deodorized and disinfected by the photocatalyst 36 of the deodorizing unit 30. It can be confirmed visually that it has been applied, and visibility can be improved. Further, the light of the deodorizing unit 30 having the light emitting means is not directly seen by the user of the refrigerator, and the catalyst can be prevented from being seen through by the light of the light emitting means.

  When the used deodorizing unit 30 is replaced with a new deodorizing unit 30, the deodorizing unit 30 is slightly depressed by pushing down the first support member 42A and the second support member 42B of the second mounting portion 42 shown in FIG. The lower end portion 30H can be removed from the first support member 42A and the second support member 42B. Thereby, the used deodorizing unit 30 can be easily removed. And the new deodorizing unit 30 pushes down the 1st support member 42A and the 2nd support member 42B for a while, and the lower end parts 44M and 45M of the right-and-left position, the lower end part 46M, the 1st support member 42A, and the 2nd support member 42B. In between, it can be fixed by the elastic force of the first support member 42A and the second support member 42B.

  Next, the case where it is necessary to attach another deodorizing agent 70 instead of installing the deodorizing unit 30 shown in FIG. 4 according to the difference in the specification of the refrigerator 1 at the site where the refrigerator 1 is assembled will be described.

  When the deodorizing agent 70 is attached as shown in FIG. 9, the opening 13 closes the opening 13 by attaching another opaque lid member 80, as shown in FIG. When the opaque lid member 80 closes the opening 13, as shown in FIG. 10, the mounting portion 47 of the opaque lid member 80 faces the upper position of the third support member 42C with a gap therebetween. Be placed.

  The attachment portion 47 and the third support member 42C detachably hold the upper end portion 71 and the lower end portion 721 of the deodorizer 70 shown in FIG. At this time, the third support member 42 </ b> C holds the deodorizing agent 70 so as to elastically press the deodorizer 70 toward the attachment portion 47 in the Z <b> 1 direction (upward direction).

  Thereby, when attaching or removing the deodorizing agent 70, the deodorizing agent 70 can be easily attached or detached by flexibly bending the third support member 42C. The structure of the deodorizing agent 70 is another member different from the structure of the deodorizing unit 30, but has activated carbon, is not equipped with a light emitting means for excitation, and deodorizes by passing cold air W.

  By the way, as shown in FIG. 10, when the opaque lid member 80 is used to close the opening 13, the deodorizing unit 70 is not attached as shown in FIG. Must be installed. If the deodorizing unit 30 is to be mounted, the mounting portion 47 of the opaque lid member 80 shown in FIG. 10 abuts against the deodorizing unit 30, so that the deodorizing unit 30 cannot be mistakenly mounted. Yes. For this reason, when the opaque lid member 80 is attached, it is impossible to attach the deodorizing unit 30. In this way, the presence of the attachment portion 47 of the opaque lid member 80 can reliably prevent erroneous mounting that attaches the deodorizing unit 30 to the deodorizing agent 70 that should be attached.

  As described above, in the assembling work of the refrigerator 1, the first support member 42A and the second support member 42B of the first mounting portion 41 and the second mounting portion 42 attach and detach the deodorizing unit 30 as shown in FIG. Can be attached as possible. Or when the specification of the refrigerator 1 differs, as shown in FIG. 10, the 3rd supporting member 42C of the attachment part 47 and the 2nd attachment part 42 can attach the deodorizer 70 so that attachment or detachment is possible.

  The refrigerator according to the embodiment of the present invention is a refrigerator in which a deodorizing unit including a light emitting unit and a catalyst excited by visible light from the light emitting unit is disposed in a refrigerator compartment side air passage of the refrigerator body, It is arranged at a position that does not cover the means, and includes a reflection portion that irradiates the inside with the reflected light of visible light in the deodorizing unit. Thereby, since the reflection part irradiates the inside with the reflected light of the visible light in the deodorizing unit, the light of the deodorizing unit having the light emitting means is not directly visible to the user of the refrigerator. Can be prevented from being seen through by the light of the light emitting means, and visibility can be improved.

  The reflection part is disposed obliquely with respect to the deodorizing unit. Thereby, since the reflection area of a reflection part can be taken large, more shining of the reflected light of visible light in the deodorizing unit which can be irradiated in a store | warehouse | chamber can be ensured more.

  The length of the reflecting portion viewed from the front is larger than the length of the reflecting portion viewed from the front. Thereby, even if it is limited space, since the reflection area of a reflection part can be taken large, more light quantity of the reflected light of visible light in the deodorizing unit which can irradiate in a store | warehouse | chamber can be ensured.

  The refrigerating room side air passage has an opening for irradiating light from the deodorizing unit into the chamber, and the deodorizing unit is attached to the refrigerating room side air passage, and the opening has a light-transmitting covering member. Is attached. Thereby, without impairing the light visibility of the deodorizing unit having the light emitting means, the light-transmitting covering member can block the opening, and the mounting stability of the light-transmitting covering member to the opening can be secured. .

  An opaque lid member is attached to the opening instead of the light-transmitting covering member, and a deodorizing agent different from the deodorizing unit can be attached. Thereby, when attaching a deodorizing agent different from the deodorizing unit, it is not necessary to pass light of the deodorizing unit having the light emitting means from the opening, so if an opaque lid member is attached to the opening, the deodorizing unit and Can be fitted with different deodorants. For this reason, the deodorizing unit in a refrigerator and the deodorizing agent different from a deodorizing unit can be used properly.

  The deodorizer is attached to the refrigerator compartment side air passage using an opaque lid member. As a result, a refrigerator assembly worker can always attach a deodorant at the manufacturing site if an opaque lid member is used, so a deodorizing agent different from the deodorizing unit must be installed at the manufacturing site. Incorrect use of attaching a deodorizing unit can be prevented.

  The structure of the opaque lid member is a configuration in which a deodorizing unit cannot be attached. As a result, the deodorizing unit cannot be attached simply by using an opaque lid member, and a deodorizing agent different from the deodorizing unit must be attached, so a deodorizing agent different from the deodorizing unit must be attached at the manufacturing site. This can prevent misuse of installing a deodorizing unit.

  The opaque lid member has an attachment portion for attaching the upper end portion of the deodorizer. Thereby, the attachment part can attach the upper end part of a deodorizing agent reliably only by using an opaque cover member.

  It has the 1st supporting member for supporting the lower end part of a deodorizing unit, and the 2nd supporting member for supporting the lower end part of a deodorizing agent. Accordingly, the first support member supports the lower end portion of the deodorizing unit, and the second support member supports the lower end portion of the deodorizing agent, so that the deodorizing unit and the deodorizing agent having different sizes are separated by separate members. Each can be supported.

  The attachment portion of the opaque lid member is provided so as to protrude at a position that prevents the attachment of the deodorizing unit. Thereby, the attachment part of an opaque cover member can prevent attaching a deodorizing unit accidentally.

  The deodorizing unit has a substrate that holds the catalyst and a light emitting means that is arranged on the substrate and irradiates visible light to the area of the catalyst, and the cool air in the refrigerator has a structure that passes through the substrate of the deodorizing unit. Thereby, the catalyst excited by the visible light of the light emitting means can deodorize the cold air passing through the substrate.

  As mentioned above, although embodiment of this invention was described, embodiment is shown as an example and is not intending limiting the range of invention. The novel embodiment can be implemented in various other modes, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.

  Each embodiment of the present invention can be used in any combination. Moreover, the structure of the refrigerator 1 shown in FIG. 1 is an example, and can employ | adopt arbitrary structures.
