In addition, a pet food of a container having a large bottom area such as a can or a foil container can be secured with a small partition plate 54 and partitioned the heat storage room 10 into a substantially square shape.

  As shown in FIGS. 2 to 3B, the side cover 60 is a peripheral body whose cross-sectional area is expanded downward, and a groove 61 in which the protruding edge 33 of the flange 30 of the inner container 20 engages with the upper end portion. Is formed, and the outer edge in the plate thickness direction is thinned at the lower end portion to form a protruding edge 62.

  As shown in FIGS. 2 to 3B, the bottom cover 70 is a tray type, and a groove 73 that engages with the protruding edge 62 of the side cover 60 is formed at the upper end of the side wall 72 that rises while curving from the bottom plate 71. ing. A rectangular inner wall body 80 is erected at the center of the bottom plate 71. Of the two opposing first side walls 81 and second side walls 83 of the inner wall body 80, the first side wall 81 parallel to the short side of the bottom plate 71 is a large U along the bottom plate 21 and the long side wall 23 of the inner container 20. It has a letter-shaped notch 82. The bottom plate 84 of the inner wall body 80 is formed by raising a part of the bottom plate 71 of the bottom cover 70. Further, a leg support 74 that receives the support leg 24 of the inner container 20 is erected beside the first side wall 81 outside the inner wall body 80. A through hole 75 for passing the port 76 is formed in the center of the leg support 74. Two each of the leg supports 74 are provided beside the two first side walls 81, for a total of four.

  As shown in FIGS. 2 and 5, the heater 90 is a flexible line heater.

Yes. The heater 90 heats the bottom plate 21 and the long side wall 23 to dissipate heat to the warming chamber 10, and further transfers heat from the bottom plate 21 to the partition plates 50 and 53, so that the main body plates 51 and 54 function as heat sinks. Warm up. Moreover, since the partition plates 50 and 53 are in contact with the bottom plate 21 over a wide area by the flange plates 52 and 55, heat transfer efficiency is good, and a high temperature holding effect is obtained. The heater 90 is preferably installed along the partition plates 50 and 53. With such an arrangement, the heat transfer distance from the heater 90 to the partition plates 50 and 53 can be shortened as much as possible to increase the heat transfer efficiency. In the heat insulating chamber 1 of the illustrated example, a heater 90 is attached along the corresponding position of the large partition plate 50. The heater 90 is mounted in a manner that crosses the corresponding position of the small partition plate 53. However, the heater 90 has a narrow interval between the folded heaters 90, and the heat transfer distance to the small partition plate 53 is short. Correspondingly, the heat transfer efficiency is good.

  As shown in FIG. 5, as a temperature sensor, a thermistor 91 and a thermostat 92 are attached to the back surface of the bottom plate 21 of the inner container 20 after being attached to the sheet 94 in the same manner as the heater 90. The thermistor 91 and the thermostat 92 detect the temperature of the bottom plate 21 heated by the heater 90, and the heater 90 is controlled based on the detected temperature so that the temperature in the temperature-retaining room 10 is within a predetermined temperature range. The The thermistor 91 can detect the temperature with high accuracy and can accurately control the temperature. On the other hand, the thermostat 92 cuts off the power supply to the heater 90 when the temperature rises. By using two types of temperature sensors having different characteristics in this way, accurate temperature management and high safety can be realized.

  The thermistor 91 and the thermostat 92 are preferably attached to corresponding positions of the partition plates 50 and 53, that is, directly below or in the vicinity of the partition plates 50 and 53. Since the partition plates 50 and 53 serve as a heat transfer path and function as a heat radiating plate, more accurate temperature management is possible by detecting the temperature near the partition plates 50 and 53. In the heat insulating chamber 1 of the illustrated example, the thermistor 91 and the thermostat 92 are attached immediately below the small partition plate 53 and in the vicinity of the large partition plate 50.

  The heater 90, the thermistor 91, and the thermostat 92 are connected to the control board 93 as shown in FIG. 3B.

  The method of attaching the heater 90 and the temperature sensor to the inner container 20 is not limited to the method of attaching the heater 90 and the temperature sensor via the sheet 94, and may be directly attached to the inner container 20. When the sheet 94 is used, the heater 90 and the temperature sensor can be affixed on the flat sheet 94, and the support legs 24 of the inner container 20 do not interfere with the work, so that the workability is good and the contents are three-dimensional. Attachment to the container 20 can be as simple as sticking the sheet 94.

The appropriate temperature of the pet food is 38 to 42 ° C., and the above-described pet food warmer 1 is controlled by the heater, thermistor 91 and thermostat 92 so as to warm the pet food contained in the warming chamber 10 to the temperature within the above range. .
[Assembly of a pet food warmer]
Each component mentioned above is assembled as follows.

  First, the protruding edge 62 of the side cover 60 is inserted into the groove 73 of the side wall 72 of the bottom cover 70. Next, as shown in FIG. 6, the inner container 20 is fitted into the notch portion 82 of the inner wall body 80, the support leg 24 of the inner container 20 is inserted into the leg holder 74 of the bottom cover 70, and the groove 61 at the upper end of the side cover 60. The protruding edge 33 of the flange 30 of the inner container is inserted into the inner container 20, and the inner container 20 is supported by the leg holder 74 of the bottom cover 70 and the first side wall 81 of the inner wall body 80. Further, a cord connecting the heater 90, the thermistor 91, the thermostat 92 and the control board 93 is drawn out of the inner wall body 80 from an escape portion 82a (see FIG. 2) provided in one notch portion 82. Further, as shown in FIG. 3B, the bolts 76 are also inserted into the through holes 75 of the leg holders 74 from the outer surface side of the bottom cover 70 and screwed into the support legs (internal threads) 74 of the inner container 20. Thereby, these are integrally couple | bonded in the aspect which pinches | interposes the side cover 60 with the inner container 20 and the bottom cover 70. FIG.

  In the assembled state, the inner container 20 is fitted in the notch 82 of the inner wall body 80, and the first side wall 81 and the second side wall 83 are inserted between the inner container 20 and the side cover 60. The notch 82 occupies most of the area of the first side wall 81, but the left and right sides of the notch 82 and the portions left below are used as spacers to form the inner wall body 80, the bottom plate 21 of the inner container 20, and the length. A space 100 having a U-shaped cross section is formed between the side wall 23 and the side wall 23. The inner wall body 80 covers the heater 90 attached to the bottom plate 21 and the long side wall 23 of the inner container 20, and the space 100 becomes a heater chamber. Since the heater 90 is covered with the inner wall body 80 to prevent the heat from being dissipated, the heat generated by the heater 90 is efficiently used for heating the warming chamber 10. Further, the hanging portion 32 of the flange 30 of the inner container 20, the side cover 60, and the bottom cover 70 form a housing of the heat insulating chamber 1, and a space is formed between the housing and the short side wall 22 and the inner wall body 80 of the inner container 20. 101 is formed, and this space 101 functions as a heat insulating chamber partitioned from the heater chamber 100 by an inner wall body 80. The heat insulating chamber 101 is used as a mounting location for the control board 93 while keeping the room temperature by blocking the thermal storage room 10 from outside air. Since the heat insulating chamber 101 is partitioned by the heater chamber 100 and the inner wall body 80, there is almost no increase in the room temperature, and the control board 93 is not affected by the heat of the heater 90.

  Depending on the above, the above-described pet food warmer 1 efficiently partitions the pet food P accommodated in the warm room 10 by dividing the warm room 10 into a plurality of rooms by the partition plates 50 and 53 functioning as heat sinks. Can be warmed up. In addition, since the pet food P is not opened and is accommodated in the warm chamber 10 as it is in a packaging container, the warming operation is easy. Moreover, a plurality of pet foods P can be accommodated by partitioning the inside of the warm storage chamber 10 into a plurality of rooms, and foods with appropriate temperatures can be given to the pets as needed. These effects can be realized by a simple heat insulation structure in which a heater is attached to the bottom plate of the greenhouse and a partition plate is attached.

  In addition, since a plurality of accommodated pet foods P can be executed in a first-in first-out manner by marking them using the indicator 35, it is possible to prevent the inconvenience that a specific pet food is kept warm without being used for a long time. Can do.

  The heat insulating box for pet food of the present invention is not limited to the above-described form.

  The number of partition plates is not limited, and at least one partition plate is included in the technical scope of the present invention. In addition, it can be arbitrarily set whether the partition plate is detachable or fixed. Further, the partition plate may have an L-shaped cross section in which a gutter plate projects from one of the main body plates.

  The heater is required to be attached to at least the bottom plate of the inner container in order for the partition plate to function as a heat radiating plate, and the heater on the side wall is optional. Moreover, the side wall which attaches a heater can also be set arbitrarily.

  Since the inner container and the partition plate that form the warming room serve as a heat transfer path, they can be formed of a metal having high thermal conductivity in addition to the resin.

  INDUSTRIAL APPLICABILITY The present invention can be used as a heat insulation chamber that warms pet food without opening it.
