BACKGROUND OF THE INVENTION
The present invention relates to a partition wall structure of a temperature refrigeration apparatus used in hospitals and schools.
[0002]
[Prior art]
For example, in hospitals, hotels, etc., a distribution car is used as a warming / refrigeration apparatus in which a warming room and a refrigerating room are defined adjacent to each other by a partition wall arranged inside the main body. In this distribution vehicle, the partition wall is configured so that a tray in which the hot food placing part and the cold food placing part are connected via the connecting part can be accommodated across the warm room and the cold room. It is. That is, the partition wall is configured by stacking a plurality of unit partition walls formed in a substantially box shape with the lower surface open at predetermined intervals in the vertical direction, and each unit partition wall protrudes from the lower surface opening. A movable member capable of abutting the lower surface (contact surface) with the upper surface (receiving surface) of the lower unit partition wall facing each other is arranged to be movable up and down. The tray is inserted between the tray and the lower unit partition wall while lifting the movable member, so that the hot food placing portion is housed in the warm room and the cold food placing portion is placed in the cold room. Can be accommodated.

Further, the movable member is always elastically biased downward by a leaf spring disposed on the upper portion thereof, and is configured so as to elastically abut on the receiving surface of the lower unit partition wall. , Ensuring airtightness between the warm room and the cold room.
[0004]
[Problems to be solved by the invention]
In the arrangement vehicle, if juice or the like spilled when the tray is put in and out is left attached to the movable member, smooth vertical movement of the movable member is prevented, and the tray is smoothly put in and out. In order to eliminate this, washing with washing water is appropriately performed. In this case, since the contact surface of the movable member is in elastic contact with the receiving surface of the unit partition wall, it is difficult to remove the cleaning water adhering therebetween. That is, it is extremely complicated to remove the washing water with a cloth held by the other hand while the operator pushes up the movable member elastically biased by the leaf spring with one hand. For this reason, in many cases, the tray is accommodated in the cart after washing without sufficiently removing the washing water. At this time, the washing water remaining between the unit partition wall and the movable member is attached to the connecting portion. Therefore, every time the tray is taken in and out, the trouble that the troublesome work of wiping off the washing water attached to the connecting portion is incurred.

As shown in FIG. 3, a plurality of tray receivers 42 projecting horizontally toward the left and right refrigeration chambers 22 and 22 are disposed on the left and right sides of the intermediate wall 16 at a predetermined interval in the vertical direction. . In addition, a tray receiver 42 is disposed on the inner surface of the side wall of the main body 12 defining each warming room 20 so as to protrude horizontally toward the warming room 20 at the same height. The arrangement height of each tray receiver 42, 42 is set to be lower than the receiving surface 26b of each unit partition wall 26 in the partition wall 18 by a predetermined height.
[0015]
The tray 44 accommodated in the distribution vehicle 10 is formed in a horizontally long rectangular shape with plastic or the like, and as shown in FIG. 3, a connecting portion 44a is provided at a position slightly closer to one side than the central portion of the width. The food provided in the warm state is placed on the wide hot food placing portion 44b sandwiching the connecting portion 44a, and the food provided in the cold state is placed on the narrow cold food placing portion 44c. It has become so. And this tray 44 inserts the connection part 44a between the movable member 32 and the unit partition wall 26, and while the hot food mounting part 44b is accommodated in the warm storage room 20, the cold food mounting part 44c. Is stored in the refrigerator compartment 22, and at this time, the lower surfaces of the mounting portions 44b and 44c are supported and received by the corresponding tray receivers 42 and 42.
[0016]
[Operation of the first embodiment]
Next, the operation of the partition wall structure according to the first embodiment will be described below. The movable member 32 of each unit partition wall 26 has its abutment surface 35 elastically brought into contact with the receiving surface 26b of the corresponding unit partition wall 26 located on the lower side by the elasticity of the leaf spring 38, and the warm storage room. Airtightness between the chamber 20 and the refrigerator compartment 22 is ensured. In this state, when the tray 44 is accommodated in the distribution vehicle 10, the connecting portion 44 a of the tray 44 is pushed in so as to contact the movable member 32 disposed on the unit partition wall 26. Thereby, the movable member 32 is lifted against the elasticity of the leaf spring 38, and the connecting portion 44a is inserted between the abutment surface 35 of the movable member 32 and the receiving surface 26b of the lower unit partition wall 26, The hot food placing portion 44 b is housed in the warm room 20 and the cold food placing portion 44 c is housed in the cold room 22. At this time, the lower surface of the connecting portion 44a abuts on the receiving surface 26b of the unit partition wall 26, and the abutment surface 35 of the movable member 32 elastically contacts the upper surface of the connecting portion 44a. Airtightness between the chamber 20 and the refrigerator compartment 22 is ensured. When the tray 44 is taken out, if the tray 44 is pulled out as it is, the contact surface 35 of the movable member 32 is again elastically brought into contact with the receiving surface 26b of the lower unit partition wall 26.
[0017]
If juice or the like spilled when the tray 44 is taken in or out is left on the movable member 32, the movable member 32 is prevented from moving up and down smoothly, and the tray 44 is taken in and out. Wash with water as appropriate. That is, the inside of the main body is washed with washing water with the tray 44 removed. At the time of washing with water, the washing water enters between the abutment surface 35 of each movable member 32 and the receiving surface 26b of the unit partition wall 26, but the operator pushes the movable member 32 elastically biased by the leaf spring 38. The operation of removing the washing water while raising it is extremely complicated. Therefore, air of a predetermined pressure is blown toward the corresponding inclined surface 40 of the movable member 32 from the side of the warm room 20 or the cold room 22. Since the inclined surface 40 is inclined so as to be displaced in the center in the width direction from the upper side toward the abutting surface 35 side, the blowing pressure of the air blown to the inclined surface 40 causes the movable member 32 to act on the leaf spring. It acts to move upward against the elasticity of 38. Accordingly, the abutment surface 35 of the movable member 32 is separated from the receiving surface 26b of the unit partition wall 26, and the cleaning water adhering between the both surfaces 26b, 35 can be removed by blowing away with the air.
[0018]
That is, in the partition wall structure of the first embodiment, the cleaning water adhering between the abutment surface 35 and the receiving surface 26b can be easily removed simply by blowing air of a predetermined pressure onto the inclined surface 40 of the movable member 32. be able to. Accordingly, it is possible to prevent the tray 44 from being accommodated in the trolley 10 without sufficiently removing the washing water, and the operator can remove the washing water every time the tray 44 is taken in and out after washing. Can be released.
[0019]
[Second embodiment]
4 and 5 show the partition wall structure according to the second embodiment, except that the configuration of the movable member is different and the other parts are the same as those of the first embodiment. Only the configuration will be described. In addition, also about a movable member, the same code | symbol is attached | subjected to the same site | part as 1st Example, and the detailed description is abbreviate | omitted.
[0020]
In other words, the movable member 46 of the second embodiment is configured to receive the lower unit partition wall 26 facing the projecting end portion that projects from the lower end of the unit partition wall 26 in which the movable member 46 is disposed so as to be movable up and down. A groove 48 opened to the surface 26b side is formed over the entire length in the longitudinal direction. The lower surfaces on both the left and right sides sandwiching the groove 48 are configured as abutting surfaces 35 and 35 that contact the receiving surface 26b of the unit partition wall 26. The left and right side surfaces of the movable member 46 are formed straight from the position where the hooks 33 and 33 are formed to the lower end, but may be formed with inclined surfaces similar to those in the first embodiment.
[0021]
In the partition wall structure of the second embodiment, after the main body 12 is washed with water, a predetermined pressure of air is blown into the groove 48 from the front or rear opening, so that the movable member 46 is moved by the pressure of the air. The spring 35 is lifted against the elasticity of the spring 38, and the contact surfaces 35, 35 of the movable member 46 are separated from the receiving surface 26 b of the lower unit partition wall 26. And the washing water adhering between both surfaces 26b and 35 is blown off by the air which blows off from the inside of the groove | channel 48 to the side. That is, also in the second embodiment, the cleaning water can be easily removed simply by blowing air into the groove 48. Even if the groove 48 is formed, the right and left abutting surfaces 35 and 35 are in elastic contact with the corresponding receiving surfaces 26b, so that the airtightness between the warming chamber 20 and the refrigerating chamber 22 is suitably ensured.
[0022]
[Modification of the second embodiment]
FIG. 6 shows a modified example of the movable member according to the second embodiment. The movable member 46 is in contact with the receiving surface 26b of the opposing unit partition wall 26 on both sides in the longitudinal direction of the groove 48 formed in the movable member 46. A soft covering member 50 that can be contacted is provided. That is, in this modified example, as in the second embodiment, the cleaning water adhering between each contact surface 35 and the receiving surface 26b can be easily removed by blowing air into the groove 48. In addition, when the door 24 is opened, the groove 48 can be hidden by the cover member 50, and juice or the like can be prevented from entering the groove 48 from the front and rear end sides.
[0023]
In the configuration in which the groove 48 is formed at the protruding end portion of the movable member 46 as in the second embodiment or the modified example, the contact area between the abutment surface 35 and the receiving surface 26b is reduced, and the amount of cleaning water attached Therefore, the cleaning water can be easily removed. Further, after washing with water, for example, when the warming chamber 20 is heated and dried, the heat is easily transmitted to the groove 48, and the washing water between the surface 35 and the receiving surface 26b can be dried in a short time. .
[0024]
In each of the above-described embodiments, the case has been described in which the movable member disposed on the unit partition wall so as to be movable up and down is protruded downward. However, a configuration that is upside down with respect to each embodiment can be employed. That is, the movable member is disposed so as to protrude upward with respect to each unit partition wall, and the upper surface (receiving surface) of the movable member is elastically applied to the lower surface (receiving surface) of the unit partition wall located on the corresponding upper side. It is good also as a structure contact | abutted to. In this case, the inclination direction of the inclined surface formed on the left and right side surfaces of the movable member is such that the blowing pressure of the air from the warm room or the cold room moves away from the receiving surface of the unit partition wall. What is necessary is just to make it act so that a member may move.
[0025]
