Further, the upper partition plate 10 and the lower partition plate 11 are attached to the upper opening and the lower opening of the housing 1 in a sealed state, respectively. The front plate 8 that forms the front side surface of the housing 1 has a shape that leaves a frame around it, and is formed with an opening for taking in and out the product. In order to cover the opening in a sealed state, a packing ( A door 14 having a not-shown door is provided by a hinge 15 so as to be freely opened and closed. In addition, 16 is a handle provided on one side of the door 14 located on the opposite side of the hinge 15. The door 14 is a transparent member in a portion excluding the frame portion so that the inside of the housing 1 can be seen through the door 14. A glass 17 is provided.

  The base 3 that forms the lower part of the main body has a bottomed cylindrical shape, and has a structure in which a bottom plate and legs are provided in addition to the frame 4 that surrounds the four directions of the side surfaces, although none of them is shown. On the front side of the frame 4, which is the same arrangement surface as the door 14, together with the illumination switch 5, an operation unit 21 that also functions as a display, a drain cock 22, a drain pipe 23, a water level gauge 24, A power cord 25 for supplying a power supply voltage is disposed.

  In addition, when used as a steamer, as a steam generator for sending steam into the housing 1, although not shown here, a heating container corresponding to an evaporating dish and the heating are provided inside the frame 4. A bottom heater for heating and evaporating water stored in the container and a water tank for supplying water to the heating container are provided. In addition to this, inside the frame 4, there are a control device 29 for controlling the operation of each part, and a ring-shaped bottom heater 30 which is located above the heating container and performs drying and heating from the lower side of the casing 1. Etc. are arranged.

  As shown in FIG. 8, a pair of left and right columns 31 are erected in the housing 1, and a plurality of rails 32 are provided side by side in the vertical direction of the columns 31. Each rail 32 is provided so as to face the left and right inner surfaces of the housing 1 and lie along the front-rear direction. Each rail 32 has a horizontal portion 33 on which a shelf 35 is placed, and the horizontal portion. A folded portion 34 is formed on the upper portion 33 with a predetermined interval and restricts the upward movement of the shelf 35 placed on the horizontal portion 33. The folding part 34 is provided on the front side of the housing 1 where the door 14 is arranged, so that the shelf 35 can be inserted between the horizontal part 33 and the folding part 34 so that the shelf 35 can slide along the rail 32. It has become.

  Further, the details of the shelf 35 will be described with reference to FIG. 9. The shelf 35 is a shelf network 36 on which products are placed and displayed, and a receiving tray 37 that is located below the shelf network 36 and is detachable from the shelf network 36. In a state in which the shelf network 36 and the tray 37 are integrated, the housing 1 is detachably mounted on the pair of left and right rails 32 and is slidable. The shelf net 36 is provided with a net 39 serving as a substantial product placing portion with the outer periphery thereof being edged. In addition, a handle 40 for easily attaching and detaching the shelf network 36 from the tray 37 is provided at a part of the front edge of the outer periphery of the shelf network 36. Note that the net 39 here includes, for example, a snowboard-shaped cross, and the like, and in short, any shape in which scraps of goods, clothes of fried food, etc. can fall there. On the other hand, the tray 37 is made of a material having good thermal conductivity, such as aluminum, and a pair of rail portions 41 are formed so as to surround the left and right outer peripheral portions in a U-shape, and between the rail portions 41, 41. A bottomed concave portion 42 that slightly falls downward is formed. The tray 37 is slidably provided on the shelf network 36 by engaging the rail portions 41 of the tray 37 with both sides of the shelf network 36.

  Returning to FIG. 1 again, reference numeral 44 denotes a temperature sensor corresponding to a temperature detecting means, which detects the internal temperature of the housing 1 in which the shelf network 36 is installed and outputs a signal to the control device 29. Side heaters 45 serving as heating means are provided on both the left and right sides in a vertically elongated space surrounded by the columns 31 and the side plates 9 (see FIG. 8). As shown in detail in FIG. 8 in particular, the side heater 45 is formed by an inverted U-shaped sheathed heater and is arranged along the entire vertical direction of both side portions of the housing 1 so as to be orthogonal to each shelf 35. It is installed. The mouth portion 46 of the side heater 45 passes through the lower partition plate 11 and reaches the inside of the base 3. The penetration part of the lower partition plate 11 is attached with a mouth part 46 in an airtight state in order to prevent foreign matter from entering the inside of the base 3.

  In this embodiment, a sheathed heater having a substantially uniform watt density is used as the side heater 45 serving as the side heating means. However, a code heater that can finely variably set the watt density along the vertical direction of the housing 1 may be used. . For example, if the watt density of the side heater 45 located above the casing 1 is increased and the watt density of the side heater 45 positioned below the casing 1 is decreased, the heating temperature above the casing 1 is decreased below. It can be intentionally higher than the heating temperature. Correspondingly, if food with a higher heating temperature is displayed above the housing 1 and food with a lower heating temperature is displayed below the housing 1, heating is performed at an optimum temperature for each food. Can do. Further, for example, a horizontally long heater unit is arranged corresponding to the rail 32 that is a shelf holder, and a vertically long heater unit that is a combination of the heater units is configured as a heating means in the vertical direction of the side of the housing 1. Also good. In any case, the configuration of the side surface heating means is not limited to the side surface heater 45 as in the embodiment.

  Each of the support 31 and the rail 32 fixed to the support 31 is composed of a member having good thermal conductivity, such as aluminum, and the side heater 45 is supported by a fixing plate 47 that forms the outer side of the support 31. It is fixed in close contact with 31.

  Next, the effect | action is demonstrated about the said structure. When a switch (not shown) of the operation unit 21 provided in front of the base 3 is turned on to start operation as a heating and warming device, the bottom heater 30 disposed at the lower part of the product is energized, and the glass 7 The space surrounded by the front plate 8, the side plate 9, the upper partition plate 10 and the lower partition plate 11 whose opening is closed by the door 14 is heated and kept warm. More specifically, when the bottom heater 30 is energized to generate heat, the air around the bottom heater 30 is heated, and air convection mainly heats each member inside the housing 1.

  On the other hand, the side heater 45 provided along the support column 31 is also energized at the same time, and heat is efficiently transmitted to the entire support column 31 including the fixing plate 47 having good thermal conductivity in close contact with the side heater 45. This heat is further quickly transmitted between the members fixed to the rails 32 having the same good thermal conductivity, and is conducted to the trays 37 located on the rails 32. Further, the temperature sensor 44 detects the internal temperature inside the housing 1 and transmits a signal of the detection result to the control device 29. The control device 29 controls the bottom heater so that the internal temperature is substantially constant. 30 and the side heater 45 are controlled to cut off electricity.

  In order to display the product in such a state, first, the door 14 is opened around the hinge shaft 15 by using the handle 16, and the shelf 35 in which the shelf network 36 and the tray 37 are integrated along the rail 32. Pull out to the front of the housing 1. Then, in the state of being pulled out or in a state where the shelf network 36 is removed from the tray 37 and food (for example, croquette or Frankfurt) is placed on the shelf network 36 and the shelf network 36 and the tray 37 are integrated again. The shelf 35 is housed inside the housing 1 along the rail 32. In addition, food (commodities) are also displayed on the shelves 35 on the other tiers. The contact portion between the rail 32 and the left and right side portions of the shelf 35 and the contact portion between the rail portion 41 of the tray 37 and the left and right side portions of the shelf network 36 have no irregularities, and these members can be smoothly slid. Can do. Furthermore, the food placed on each shelf 35 is heated and kept at substantially the same temperature even if the food placed on each shelf 35 is away from the bottom heater 30 by the heat transmitted from the side heater 45 to the tray 37. Therefore, the internal temperature can be maintained uniformly without stirring the air inside the housing 1 with a fan or the like.

  Each food item displayed inside the housing 1 can always be confirmed from the outside through the glass 7 and 17 which are transparent members. Since the food waste is prevented from falling onto the lower shelf 35 by the receiving tray 37, different foods can be kept warm in the same housing 1 without worrying about such food waste falling. In addition, when the shelves 35 are mounted between the rails 32, the shelf net 36 and the tray 37 are substantially the same shape, and there is no trouble that it is difficult to see or take out the products at the time of sale.

  Thereafter, when the product is sold, depending on the position and the number of the product to be sold, the door 14 is normally opened using the handle 16 and the shelf 35 is not pulled out of the housing 1 and only the product is directly used. Take it out with a grip such as tongs. In the case of foods such as croquettes, food scraps (fried bread crumbs) adhering to the outer surface easily fall off when sandwiched with tongs, but these food scraps pass through the net 39 to the bottom of the shelf 35. It falls on the tray 37 comprised integrally. Also, depending on the food, the cooking oil may drop through the net 39, but it will also drop onto the tray 37 and not reach the lower shelf 35. In particular, the tray 37 in the present embodiment has the recess 42 formed at a position facing the net 39 on which the food is placed in a state where the shelf net 36 and the tray 37 are integrated, so that the oil reaching the tray 37 is recessed. It drops on the upper surface of 42 and does not easily flow out to the lower shelf 35.

  Further, at the time of the end of sales or periodic cleaning, the door 14 is opened around the hinge shaft 15 by using the handle 16 and the shelf 35 in which the shelf network 36 and the tray 37 are integrated along the rail 32. Then pull it out forward of the housing 1. And the rail part 41 of the saucer 37 is slid from the shelf network 36, the shelf network 36 and the saucer 37 are disassembled, and it wash | cleans separately, The shelf 35 whole can be maintained in a clean state. After the cleaning, the shelf network 36 and the tray 37 are again fitted together by sliding, and are remounted between the left and right rails 32. Then, as described above, the product is set up and displayed and sold. Since there is no unevenness in the contact portion between the rail portion 41 of the tray 37 and the left and right sides of the shelf network 36, the cleaning property is excellent. Moreover, since both members can be easily attached or detached simply by sliding the tray 37 from the shelf network 36, the cleaning property is also improved.

  Further, this food heating and warming device can selectively use not only functions as so-called heating and heat retaining but also functions as a steamer. That is, when an operation button (not shown) of the operation unit 21 is pressed and the steamer function is selected, the bottom heater is turned on instead of the bottom heater 30 and the side heater 45 being turned off, and the water stored in the heating vessel is stored. Is evaporated by heating. Thereby, for example, food suitable for a steamer such as Chinese bun can be stored in a good state. Thus, since the steam generator is provided in the lower part of the housing 1, it can be used not only as a heating and warming device but also as a steamer, and it is not necessary to install a steamer separately.

  Next, the food heating and warming device in the first embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a perspective view showing a part of the appearance of the door 14 as viewed obliquely from behind, and the configuration of the left and right side portions of the housing 1 is partially different from that shown in FIG. Other parts are the same as those shown in FIG.

  In this embodiment, the left and right side plates 9, 9 partially lie on the U-shaped glass 7, and the space formed between the outer side surface of the glass 7 and the side plates 9, 9 is used for illumination. A rod-like fluorescent lamp 13 corresponding to a lamp is arranged vertically along the vertical direction of the shelf 35 and is provided so as to be turned on and off by an illumination switch 5 serving as switching means. Further, a hood 12 is provided on the outer surface of the glass 7 in order to reflect the light emitted from the fluorescent lamp 13 to the surface of the glass 7, and a part of the hood 12 extends from the glass 7 to a portion other than the inside of the housing 1. A vertically long slit 12a that enables irradiation in the direction is provided. And the light from the fluorescent lamp 13 which leaks from this slit 12a is irradiated toward the customer side which is the opposite surface of the door 14. FIG. Although not shown, the slit 12a is provided with a transparent display member (not shown) in which merchandise advertisements and symbols are arranged.

  Moreover, the top plate 2 in the present embodiment is provided with a daylighting window 50 for taking in light from the upper part of the housing 1. The daylighting window 50 is actually covered with a transparent member such as glass in order to prevent entry of foreign matter from the outside. Instead, an illumination fluorescent lamp that performs illumination from the upper part of the housing 1 is not provided. That is, the illumination light in the room where the device is installed is used to illuminate the upper portion of the housing 1 from the daylighting window 50, and power consumption can be reduced by the amount of the fluorescent lamp for illumination. Other configurations are the same as those in the first embodiment.

  In the present embodiment, when the lighting switch 5 is turned on in a state where the product is displayed inside the housing 1, the fluorescent lamps 13 arranged on the left and right outer surfaces of the housing 1 are turned on, and the glass 7 is turned on. It passes through and illuminates the interior of the cabinet 1. Since the fluorescent lamps 13 are arranged over the plurality of shelves 35 in the vertical direction, even if the tray 37 is a non-light transmissive member such as metal that does not transmit light, it is placed on the top of the shelves 35 installed in a plurality of stages. Each product on a shelf 39 can be illuminated evenly.

  On the other hand, a part of the light from the fluorescent lamp 13 is irradiated toward the hood 12 on the side opposite to the glass 7. At that time, the light that has passed through the slit 12a irradiates a display member such as an advertisement or a symbol of a product provided in the slit 12a to draw the customer's line of sight. Thereby, the light from the fluorescent lamp 13 can enhance the display-like advertising effect to the customer by emphasizing the pattern and characters provided just before the slit 12a, and the sales promotion effect can also be expected. The illumination lamp here is not limited to the fluorescent lamp 13 in the embodiment, and may be another light source.

  Moreover, it passes through the glass lighting window 50 arrange | positioned in the upper surface part of the top plate 2, and the lighting fixture in a shop illuminates the inside of the housing | casing 1 from upper direction. Therefore, it is possible to illuminate the product on the uppermost shelf 35 that is most desired to be displayed more brightly than the product placed on the other shelf 35, thereby obtaining a sales promotion effect.

  As described above, in the present embodiment, the casing 1 whose peripheral part is covered with the glass 7 that is a transparent member, the shelves 35 arranged in the vertical direction in the casing 1, and the casing 1 In a food heating incubator provided with rails 32 that are provided on the inner surface of the side portion and serve as shelves that allow the shelf 35 to move, and fluorescent lamps 13 that are illumination devices on the outer side surface of the glass 7, the fluorescent lamps 13 are placed on the shelves 35. Are arranged along the vertical direction, and a part of the light of the fluorescent lamp 13 is irradiated on the surface of the glass 7, that is, in a direction other than the inside of the housing 1 from the glass 7.

  In this way, since the fluorescent lamp 13 on the outer side surface of the glass 7 is arranged along the vertical direction like the shelf 35 in the housing 1, the light from the fluorescent lamp 13 passes through the glass 7. Without being obstructed by the tray 37, it reaches the entire product displayed on each shelf 35 in the housing 1. Furthermore, since a part of the light of the fluorescent lamp 13 that does not pass through the glass 7 is irradiated to the outside, an illumination advertisement that uses this part of the light to stimulate consumers' demand. Can be performed.

  Next, a second embodiment of the present invention will be described with reference to FIGS. 1 and 3 to 5. 3 to 5, the vaporization container 51 is detachably provided from the inside of the housing 1, and is formed in a recess 62 formed on the door 14 side of the partition plate 61 that partitions the inside of the housing 4. is set up. In addition, a top plate 57 made of a non-magnetic material for placing the vaporization vessel 51 is provided at the bottom of the recess 62, and the vaporization vessel 51 made of a magnetic material is electromagnetically heated below the top plate 57. A heating coil 58 is provided. Note that 59 is a ferrite that prevents generation of magnetic flux from the heating coil 58 to the floor surface, and 60 is a coil base 60 that arranges the heating coil 58 in a predetermined shape. A control device 29 for adjusting the high-frequency current supplied to the heating coil 58 is arranged as a heating control means for controlling the induction heating device constituted by the top plate 57, the heating coil 58, the ferrite 59 and the coil base 60. . Further, the partition plate 61 is formed with an inclined surface 63 that falls downward toward the periphery of the recess 62 so that the recess 62 and the vaporization container 51 are positioned at the lowest portion of the main body including the housing 1 and the base 3. The bottom heater 30 described above is disposed on the glass 7 side below the inclined surface 63 and opposite to the door 14.

  On the other hand, a recess 2a is provided on the door 14 side of the top plate 2 at the top of the housing 1, and a water tank 53 corresponding to the water storage means is detachably provided with the water supply port 53a facing downward. It is done. A receiving tray 64 for receiving water from the water tank 53 is provided at the inner bottom of the recess 2a. The water tank 53 is a detachable cartridge type, and can be opened and closed in a sealed manner by a valve body 53b provided in the water supply port 53a.

  The tray 64 provided corresponding to the water supply port 53a includes a protrusion 64a that pushes up the valve body 53b that is screwed into the water supply port 53a, and has a structure that holds the constant water surface at the lower end of the water supply port 53a. In addition, the tray 64 is provided with a water supply pipe 54 that is open to communicate with the vaporization vessel 51 via an electromagnetic valve 54a. Further, a part of the bottom of the vaporization container 51 is formed in a concave shape, and a temperature sensor 65 as a detecting means for detecting the temperature of the vaporization container 51 is disposed in a part corresponding to the concave part 51a. A signal is sent to the control device 29.

  Next, the operation of this embodiment will be described. After water is supplied from the water supply port 53a of the water tank 53, when the valve body 53b is screwed into the water supply port 53a and the water tank 53 is set in the tray 64 in the upside down state, the valve attached to the water supply port 53a The body 53b is actuated by the protrusion 64a and pushed upward, and the constant water surface is held in the tray 64. At this time, water flows into the water supply pipe 54 and is held in a state closed by the electromagnetic valve 54a. Next, when operation is started by operating a switch (not shown) of the operation unit, a high-frequency current is supplied to the heating coil 58 constituting the induction heating device, and the vaporization vessel 51 made of a magnetic member is heated by electromagnetic induction. Here, when there is no water in the vaporization vessel 51, the entire bottom of the vaporization vessel 51 is heated, and the temperature of the concave portion 51a to which the temperature sensor 65 is attached similarly rises. And the temperature rise of the recessed part 51a is detected by the temperature sensor 65, and it determines with the control apparatus 29 that there is no water in the vaporization container 51. FIG.

  Therefore, when the electromagnetic valve 54a is opened for a certain period of time, the water in the water supply pipe 54 flows into the vaporization vessel 51, and water is automatically supplied from the water tank 53 to the tray 64 in order to maintain the constant water surface in the tray 64. In this way, a certain amount of water is supplied into the vaporization vessel 51 by the opening / closing operation of the electromagnetic valve 54 a, and steam is generated by heating by the heating coil 58. And when a vapor | steam is continuously generated, the water in the vaporization container 51 will vaporize, a water surface will fall gradually, and the recessed part 51a will be exposed. As a result, only the exposed recess 51a rises in temperature. The temperature sensor 65 is provided for automatically supplying water by operating the solenoid valve 54a for a certain period of time when the temperature rise of the recess 51a is detected. In this way, continuous operation can be performed until the water in the water tank 53 runs out.

  The heating coil 58 is energized by the operation start operation, and the bottom heater 30 and the side heater 45 are energized simultaneously. Then, the heat generated by the side heater 45 is transmitted through the support column 31, and the heat generated by the bottom heater 30 is transmitted through the partition plate 61 to both heat the glass 7 and warm the interior air inside the housing 1. . In particular, by reducing the temperature difference between the vapor generated by the vaporization container 51 and the inner surface of the glass 7, it is possible to prevent the glass 7 from being fogged or condensed.

  Further, even if water vapor is condensed to form water droplets and flows down along the inner surface of the glass 7, it accumulates in the outer peripheral gap between the recess 62 and the vaporization container 51 through the inclined surface 63. Here, since the vaporization container 51 is heated so as to generate steam therein, the outer surface of the vaporization container 51 is also at a temperature sufficient to generate steam. Therefore, the water droplets that have flowed in are heated again, and become steam and fill the interior.

  In addition, since the water droplets that flowed in are condensed from the water once vaporized inside the vaporization vessel 51, they do not contain impurities such as a salt component contained in tap water. Therefore, almost no residue is generated in the recess 62 due to re-evaporation of the water droplets that have flowed. Therefore, the recess 62 can be easily cleaned. Then, when steam is generated from the vaporization container 51 and the interior is thermally stabilized or after a predetermined time has elapsed, the energization of the side heater 45 and the bottom heater 30 is stopped or controlled.

  When products such as Chinese buns and meat buns are displayed and displayed on the shelf network 36 in a state where steam is generated, the products can be sold in a fluffy state. When cleaning the vaporization container 51, after opening the door 14 and removing the shelf network 36 in the warehouse, the vaporization container 51 is lifted upward so as to avoid the water supply pipe 54 and taken out from the interior. Thereafter, the vaporization container 51 is cleaned with a sink, and a hand is inserted from the position where the door 14 is opened so that the temperature sensor 65 coincides with the recess 51b, and the vaporization container 51 is set on the top plate 57.

  As described above, in the present embodiment, the casing 1 partially surrounded by the glass 7 which is a transparent member, the openable / closable door 14 provided in one direction of the casing 1, and the casing 1 In the food heating and incubator provided with a vaporization container 51 as a container provided in the lower part of the container, the vaporization container 51 is disposed on the door 14 side, and a bottom heater 30 or a side surface as a heating means is disposed on the glass 7 side away from the door 14. A heater 45 is arranged.

  Thus, since the vaporization container 51 is arrange | positioned in the site | part in which the hand by the side of the door 14 is easy to reach, the cleaning of the vaporization container 51 can be made easy and a hygiene surface can be improved. Further, the glass 7 side away from the door 14 is heated by the heat from the bottom heater 30 and the side heater 45, and the temperature difference between the surface of the glass 7 and the water vapor is reduced, so that the surface of the glass 7 accompanying the generation of the vapor is reduced. Clouding and condensation can be prevented. Furthermore, by disposing the vaporization container 51 on one side close to the door 14 side of the device, a large space can be secured inside on the side away from the door 14 of the vaporization container 51, and the degree of freedom of component arrangement such as the control circuit 29 is increased. improves.

  In this embodiment, the vaporization container 51 is provided at the lowest position of the main body composed of the housing 1 and the base 3. If it carries out like this, even if the condensed water droplet flows along the inner surface of the glass 7 which comprises the housing | casing 1, since the vaporization container 51 exists in the lowest position, it becomes water vapor | steam again with the heat | fever of a vaporization container. The inside of the housing 1 is filled. Thereby, the steam generated from the vaporization container 51 can be sent into the housing 1 without waste.

  In addition, in this embodiment, the partition plate 61 that divides the housing 1 and the base 3 is provided with a recess 62 for disposing the vaporization container 51 and an inclined surface 63 that falls downward toward the periphery of the recess 62. The water drops dripping from the glass 7 are configured to accumulate in the outer peripheral gap between the recess 62 and the vaporization container 51 through the inclined surface 63. If it does in this way, the water droplet which flowed into the recessed part 62 will be heated again by the vaporization container 51, will be filled with water vapor | steam, but the water droplet which flowed in contains impurities, such as a chlorine component contained in tap water etc. In addition, cleaning in the recess 62 is facilitated.

  In the present embodiment, the side heaters 45 are arranged on both the left and right sides of the glass 7, while the other bottom heater 30 is also arranged on the lower surface of the glass 7, so that the entire surface of the glass 7 is effectively fogged. Can be prevented.

  A third embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a partial sectional view showing a longitudinal section of the base 3 portion. In the figure, the vaporization container 51 is installed in a recess 62 of the partition plate 61 so as to be detachable from the inside of the cabinet, and a bottom plate of the top plate 57 made of a non-magnetic material and a top plate 57 An induction heating device including a heating coil 58 as a lower heating device, a ferrite 59, and a coil base 60, a control device 29, and the like are provided.

  In addition, the interior of the cabinet is divided by a partition plate 61, and a water tank 53 that opens upward is provided at the top, and the bottom side surface of the water tank 53 is open to communicate with the vaporization vessel 51, and the flow path is opened and closed in the middle. A water supply pipe 54 having an electromagnetic valve 54a is provided. A part of the bottom portion of the vaporization container 51 is formed in a concave shape, and a temperature sensor 65 as a detecting means is arranged in a portion corresponding to the concave portion 51a, and an output signal of the temperature sensor 65 is sent to the control device 29. Yes. In addition, the water level meter 24 communicates with the water tank 53 through a pipe (not shown). Reference numeral 56 denotes a packing for hermetically holding the door 14.

  Next, the operation of this embodiment will be described. When the operation unit 21 is switched on and the operation is started, the heating coil 58 constituting the induction heating device is energized and the vaporization vessel 51 is heated. In a state where there is no water in the vaporization container 51, the entire bottom of the vaporization container 51 is heated, and the temperature of the recess 51a similarly rises. When the temperature sensor 65 detects a temperature rise and the control device 29 determines that there is no water, the electromagnetic valve 54a is opened for a certain period of time to automatically supply water, and a constant amount of water is supplied into the vaporization container 51, and induction is performed. Steam is generated by heating the heating device.

  Further, when steam is continuously generated, the water in the vaporization vessel 51 is vaporized, the water surface gradually decreases, and the recess 51a is exposed. As a result, only the exposed recess 51a rises in temperature. Moreover, the temperature sensor 65 detects the temperature rise of the recessed part 51a, operates the solenoid valve 54a, and supplies water automatically. The continuous operation is continued until the water in the water tank 53 runs out.

  When products such as Chinese buns and meat buns are displayed and displayed on the shelf network 36 in a state where steam is generated, the products can be sold in a fluffy state. When cleaning the vaporization container 51, after opening the door 14 and removing the shelf network 36 in the warehouse, the vaporization container 51 is lifted upward so as to avoid the water supply pipe 54 and taken out from the interior. Thereafter, the vaporization container 51 is cleaned with a sink, and a hand is inserted from the position where the door 14 is opened so that the temperature sensor 65 coincides with the recess 51b, and the vaporization container 51 is set on the top plate 57.

  As described above, in this embodiment, in a food heating incubator provided with the casing 1 and the vaporization container 51 provided at the lower part of the casing 1, heating as a heating device for electromagnetically heating the vaporization container 51 is performed. A coil 58 is provided. If it does in this way, vapor will be generated from vaporization container 51 by carrying out electromagnetic induction heating of vaporization container 51 by heating coil 58. At that time, if each part around the vaporization vessel 51 is made of a non-magnetic material, unnecessary portions other than the vaporization vessel 51 are not heated, so that the time from the start of operation to the generation of steam is shortened and consumed. Electric power can be reduced.

  Furthermore, in the present embodiment, since the vaporization container 51 is detachably provided, the vaporization container 51 can be easily removed and cleaned. Therefore, the cleaning property of the vaporization container 51 is improved and the hygiene aspect can be improved.

  In addition, in this embodiment, when the temperature of the vaporization container 51 is detected by the temperature sensor 65 as detection means, and the temperature of the vaporization container 51 rises in a state where there is no water in the vaporization container 51, for example, opening / closing means such as an electromagnetic valve 54a Since the water is supplied from the water tank 53, the electromagnetic valve 54a is closed at the start of operation, heating is started in the absence of water in the vaporization vessel 51, and the time until the generation of steam after the start of operation is greatly increased. Can be shortened.

  A fourth embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a schematic diagram showing the arrangement of the rails 32 that are shelf holders disposed on the column 31. As shown in FIG. 1, the rails 32 that store and hold the shelves 35 are respectively disposed on the columns 31 on both sides of the housing 1. However, in the case where different products are displayed and sold in the common housing 1, there are cases where it is desired to change the interval between the shelves 35 because the heights of the products to be displayed are different. Therefore, in the present embodiment, when the rails 32 for storing and holding the shelves 35 in a plurality of upper and lower stages are arranged on the support columns 31, the storage spaces of the shelves 35 can be set to different intervals a and b. Rails 32 are arranged at the respective parts (A) and (B). Further, below the rail 32 on which the shelf 35 is arranged at the lowermost stage, there is a rail 32a as a spare shelf storage unit that is located in the part (C) and can store only the shelf 35 without placing products. Arranged.

  And since the height of goods will differ if the goods to display differ, each shelf 35 is inserted in the rail 32 which adapts according to the goods to display. Accordingly, the space between the shelves 35 and 35 on which the short products are displayed is low, and conversely, the space between the shelves 35 and 35 on which the high products are displayed can be increased. For example, in FIG. 7, when the shelf 35 is inserted into the rail 32 in the part (A), the vertical distance a between the shelves 35 and 35 is short, the number of the shelf 35 is increased to five, and the height is short. Suitable for displaying goods. In addition, when the shelf 35 is inserted into the rail 32 in the (B) part, the vertical distance b between the shelves 35 and 35 is long, the number of the shelf 35 is reduced to four, and a tall product is displayed. Suitable for doing. Of course, the shelf 35 can be inserted at any other position.

  As described above, the structure in which the number of the shelves 35 can be changed in accordance with the height of the product is particularly suitable for a structure that can be used by switching between a heating and warming device and a steamer as in this embodiment. That is, the products to be displayed are different between the heating incubator and the steamer, and the heights are inevitably different. Therefore, if the height of the shelf 35 can be arbitrarily changed, it can be used in either case. So there is no wasted space.

  In this way, if it is possible to switch between both the heating and warming device and the steaming device, it is possible to cope with changes in sales trends in each region without replacing the heating and warming device body. For example, when used as a steamer, the food to be displayed is displayed in five stages (using part A) because the height of the products handled, such as meat buns and Chinese buns, is substantially the same. On the other hand, when products such as croquettes, potatoes, and Frankfurt are kept warm, the heights of these products are different, so the number of shelves is reduced by one and the intervals between the shelves are widened (B section is used).

  A rail 32 a that can store a spare shelf 35 is provided at the lowermost part (C) of the column 31. As a result, for example, when the shelf 35 is stored in the rail 32 of the (B) part, a single unused shelf 35 is generated. In this case as well, the excess shelf 35 is reserved on the rail 32a of the lowermost (C). Can be stored. Therefore, without losing the unused shelf 35, the shelf 35 is preliminarily stored in a heat-sterilized state and can maintain a good sanitary state.

  Further, after that, when the shelf 35 is stored again in the rail 32 of the part (A) and the shelf a is used at a narrow interval a, the spare shelf 35 stored in the rail 32a is already stored in a heated state. Therefore, even if this shelf 35 is used immediately, the temperature of the products displayed on the shelf network 36 does not decrease. Further, if the sale of the product is continued, unlike products such as Chinese buns and meat buns, for example, croquette clothing scraps or fried oil will fall on the tray 37 and the shelf 35 needs to be cleaned. In this case, the spare shelf 35 stored in the lowermost rail (C) 32a is taken out and replaced with a shelf 35 that needs to be cleaned to clean the dirty shelf 35 and the spare shelf. The product is displayed in 35 and is continuously sold. Also in this case, since the spare shelf 35 is already stored in a heated state, even if the shelf 35 is used immediately, the temperature of the product does not decrease. Therefore, in any case, preheating time is not required, and sales efficiency can be improved.

  Furthermore, a storage unit that can store one shelf 35 more than the number of shelves 35 in advance without changing the number of shelves 35 is provided, and the spare shelves 35 stored in this storage unit can be used as needed. May be.

  As described above, in this embodiment, the food heating and warming device including the casing 1, the shelf 35 provided in the casing 1, and the rails 32 as a plurality of receiving portions that movably store the shelf 35. The rails 32 are arranged so that the distance between the shelves 35 can be varied, and the rails 32 a are provided in the housing 1 as storage units for storing the unnecessary shelves 35 and spare shelves 35. .

  If it does in this way, since the rail 32 is arrange | positioned so that the distances a and b between the shelves 35 can be varied, the space | interval of the shelves 35 can be adjusted according to the height of the goods to display. At this time, if the intervals a and b of the shelves 35 are increased and the number of shelves 35 is reduced, an extra shelf 35 is generated. This unnecessary shelf 35 is a spare shelf storage unit in the housing 1. Since it can be stored in the rail 32a, it is not lost. Moreover, since the spare shelves 35 can be stored in the rails 32a when products are sold on the shelves 35, the shelves 35 displayed at the time of cleaning or the like may be replaced with the spare shelves 35. It can be sold in good condition without lowering the temperature. Further, while the spare shelf 35 is preheated in the housing 1, water droplets and the like adhering during cleaning are removed in advance, and the spare shelf 35 is sterilized by heating. Can be sold.

  A fifth embodiment of the present invention will be described with reference to FIGS. FIG. 8 is an exploded perspective view around the rail 32 holding the shelf 35, and FIG. 9 is a perspective view showing components constituting the shelf 35 for displaying products. The rail 32 of the shelf holder that stores and holds the shelf 35 is disposed on the column 31 on the side of the housing. In this embodiment, each member provided in the housing 1, specifically, each surface of the shelf network 36, the rail 32, the column 31, the upper partition plate 10, the lower partition plate 11, the fixing plate 47, and the tray 37. A fluorine coating (not shown) is formed on top.

  The operation of the above configuration will be described. Since the shelf 35 is repeatedly inserted into or pulled out from the rail 32 of the shelf receiver, a frictional force acts between the rail 32 and the tray 37 that constitutes the shelf 35, so Such a problem may occur. In particular, when the material of the rail 32 and the receiving tray 37 is the same, it is easy to produce a twist. Therefore, in this embodiment, fluorine coating is applied to one of the sliding surfaces of the shelf 35 and the rail 32 of the shelf holder that slide with each other. That is, by applying fluorine coating to the rail 32 of the receiving portion into which the shelf 35 is inserted, or the rail portion 41 that is the sliding portion of the receiving tray 37 that constitutes the shelf 35, the friction between the shelf 35 and the rail 32 of the shelf receiving portion is applied. The force can be reduced, and the sticking by sliding can be prevented.

  Further, since the frictional force is reduced, the shelf 35 can be smoothly inserted into and removed from the rail 32. Furthermore, even when the rails 32 and the shelf 35 are soiled by food, the dirt attached to the part coated with fluorine can be easily removed, so that the cleanability is improved, and the cleanliness important for the food heating and warming device. It becomes easy to ensure the thickness.

  In this embodiment, at least the sliding part of the rail 32 and the shelf 35 is coated with fluorine, but instead of fluorine coating, a tape is attached, or a resin having characteristics equivalent to fluorine is coated, Similarly, it is possible to reduce the friction of the sliding part.

  As described above, in the present embodiment, in the food heating and warming device including the housing 1, the shelf 35 provided in the housing 1, and the plurality of receiving portions, that is, the rails 32, in which the shelf 35 is movably stored. The inner surface of the rail 32 that is in contact with the rail portion 41 that is the sliding portion of the shelf 35, that is, the rail surface, is coated with fluorine.

  In this case, since the rail surface of the rail 32 is coated with fluorine, the friction coefficient of the rail surface is reduced, the frictional force is reduced, and the operation of the shelf 35 can be performed smoothly. . Further, even if the rail surface of the rail 32 is soiled by food, the dirt adhering to the fluorine coating can be easily removed, so that the cleanability is improved.

  In the present embodiment, the rail portion 41 which is the sliding portion of the shelf 35 is coated with fluorine. In this case, since the fluorine coating is applied not only to the inner surface of the rail 32 but also to the rail portion 41 that is the sliding portion of the shelf 35, the operation of the shelf 35 can be performed more smoothly. Moreover, even if the rail part 41 becomes dirty with foodstuffs, it can be easily cleaned.

  A sixth embodiment of the present invention will be described with reference to FIGS. FIG. 10 is a side cross-sectional view including a portion facing the door 14 in the glass 7 formed in a U shape as viewed from above. In FIG. 10, the glass 7, the upper partition plate 10, and the lower partition plate 11 constitute an outer case of the housing 1 as described above. Here, a glass heater 38 as a heating means is fixed to the lower part of the inner surface of the glass 7. Here, the glass heater 38 is extended to the left and right ends along the horizontal direction of the glass 7 so that the entire glass 7 can be heated uniformly. The glass heater 38 is connected to the same circuit as the side heater 45 and is turned on / off together. Further, a receiving tray packing 43 as an elastic member for stably holding the receiving tray 37 and the shelf 35 is disposed on the front end surface portion of the receiving tray 37 constituting the shelf 35, and the tip of the receiving tray packing 43 is made of glass 7. Close to the inside.

  Next, the operation of this embodiment will be described. When the bottom heater 30 and the side heater 45 are energized to heat the food displayed in the housing 1, water vapor is generated from the heated food and the water vapor is filled in the cabinet. Then, since the outside air temperature is usually lower than the temperature inside the cabinet, a temperature difference occurs between the inside and outside surfaces of the glass 7, the water vapor in the vicinity of the inside surface of the glass 7 is cooled, and condensation occurs there. If dew condensation occurs, it is difficult to see the products displayed in the warehouse, and even if they are visible, the purchasing motivation power declines, which is not preferable.

  On the other hand, according to the heating incubator of the present embodiment, the glass heater 38 provided at the lower inner surface of the glass 7 is energized simultaneously with the side heater 45 to generate heat, so that the heat of the glass heater 38 is heated to the lower portion of the glass 7. It is conveyed by conduction. Thereby, the temperature of the glass 7 rises moderately and it can prevent that dew condensation arises on the inner surface of the glass 7.

  Here, fixing the glass heater 38 to the lower part of the inner surface of the glass 7 is based on the following circumstances. That is, since the water vapor generated from the food is warm, it once rises in the cabinet. However, when warm water vapor rises in the chamber, the temperature in the upper portion of the chamber also rises, and when the glass heater 38 is not provided, condensation tends to occur at the lower portion of the glass 7. Therefore, by installing the glass heater 38 particularly on the lower part of the inner surface of the glass 7, it is possible to prevent condensation from occurring in this part.

  In addition, since the receiving tray packing 43 is fixed to the inner surface of the glass 7 at a position corresponding to each receiving tray 37, the heat generated by the side heater 45 causes the receiving tray 37 and receiving tray packing 43 of the shelf 35 to move from the rail 32. The heat is transferred to the inner surface of the glass 7 via. Thereby, the inner surface other than the lower part of the glass 7 can also be heated substantially uniformly, and it is possible to prevent dew condensation from occurring over the entire inner surface of the glass 7.

  As described above, in the present embodiment, the lower surface of the glass 7 in the food heating and warming device provided with the casing 1 made of the glass 7 which is a transparent member and the shelf 35 disposed in the casing 1. A glass heater 38, which is a heating means, is provided along with.

  In this way, the inner surface of the glass 7 can be warmed by the heat from the glass heater 38 along the lower surface of the glass 7, so that the inner surface of the glass 7 can be prevented from being fogged. The cloudiness can be eliminated quickly.

  Moreover, since the end surface of the shelf 35 is in contact with the glass 7 directly or via the tray packing 43 that is an elastic member, heat is transferred from the end surface of the shelf 35 to the inner surface of the glass 7, and the inner surface of the glass 7 is fogged. Can be further prevented. Moreover, even if fogging occurs, the fogging can be eliminated more quickly.

  Furthermore, in this embodiment, since the tray packing 43 is interposed between the glass 7 and the tray 37 of the shelf 35, no extra force is applied to the glass 7 when the shelf 35 is put in and out, and in a stable state. The shelf 35 can be held in the housing 1.

  A seventh embodiment of the present invention will be described with reference to FIGS. FIG. 11 is a partial cross-sectional view taken along the line XX of FIG. FIG. 12 is an enlarged view thereof, and FIG. 13 is a schematic view showing a side surface of the heating and warming device. In the present embodiment, as shown in FIG. 11, the incubator combines two glasses 6 and 7 to form an integral double glass that partitions the inside of the housing 1 from the outside air. Although all the glasses 6 and 7 are substantially U-shaped, the inner glass 6 has a relatively large U-shaped bent portion, for example, a corner 6a having a radius of about R = 70 mm. On the other hand, the outer glass 7 has a relatively small U-shaped bent portion, for example, a corner portion 7a having a radius R of about 20 mm.

  The space between the inner glass 6 and the outer glass 7 is configured to maintain a substantially uniform gap except for the corners 6a and 7a. Moreover, since the curvature radii of the corners 6a and 7a of the respective glasses 6 and 7 are different between the corners 6a and 7a, a wide gap can be secured. Incidentally, the larger the difference in the radius of curvature of the corners 6a and 7a, the wider the space between the corners 6a and 7a.

  For example, in the above example, a space having a diameter of about Φ = about 30 mm at the maximum can be secured between the corners 6a and 7a. In this space, vertically long fluorescent lamps 26 as illumination devices are arranged vertically. Specifically, as shown in FIG. 13, the fluorescent lamp 26 is erected between the upper partition plate 10 and the lower partition plate 11. On the other hand, the upper side of the top plate 2 is openable so that the fluorescent lamp 26 can be attached and detached. Further, on the inner surface of the corner portion 7a of the outer glass 7 on the side opposite to the door 14, a reflecting plate having a semicircular cross section for reflecting light toward the interior over approximately half of the periphery of the fluorescent lamp 26. 27 is attached.

  Next, the operation of this embodiment will be described. The fluorescent lamp 26 is turned on by turning on an illumination switch (not shown). Most of the light from the fluorescent lamp 26 passes through the inner glass 6 and is irradiated into the interior of the housing 1 while being reflected directly or by the reflecting plate 27. Further, since the fluorescent lamp 26 and the reflector 27 are installed at a substantially right angle with respect to the shelf network 36, the light reaches the back of the shelf network 36, and the food on the shelf network 36 can be illuminated almost evenly. .

  Further, since the fluorescent lamp 26 and the reflecting plate 27 are disposed at the corners 6a and 7a of the substantially U-shaped glasses 6 and 7 on the opposite side of the door 14, the food is almost seen from the consumer's direction. Can shed light on Therefore, it is possible to shine light on the displayed food without casting a shadow. Further, since the reflecting plate 27 is disposed on the inner surface of the corner 7a of the outer glass 7, the light emitted from the fluorescent lamp 26 is not directly irradiated to the consumer side, and the illumination is gentle to the consumer's eyes. It can be performed.

  The glass surface can be easily cleaned using a cloth or the like because both the inner glass 6 and the outer glass 7 have no surface irregularities. In addition, since the top plate 2 can be opened and closed when replacing the fluorescent lamp 26, the top plate 2 can be opened and the fluorescent lamp 26 can be easily inserted and removed from the top of the housing 1.

  As described above, in the present embodiment, in the food heating and warming device provided with the casing 1 partially made of the glass 6 and 7 as the transparent member and the shelf 35 disposed in the casing 1, the casing A fluorescent lamp 26 as an illumination device is arranged between two glasses 6 and 7 that partition the inside of 1 and the outside air.

  In this case, since the fluorescent lamp 26 as an illumination device is disposed between the two glasses 6 and 7 that partition the inside of the housing 1 and the outside air, the inner and outer glasses 6 and 7 are free of irregularities and the cleaning property is good. In addition, cleaning can be performed without being disturbed by the fluorescent lamp 26. Further, there is no need to provide a projection or the like for accommodating the fluorescent lamp 26 on the outer glass 7, and there is an advantage that the product displayed inside the housing 1 is easy to see.

  Next, an eighth embodiment of the present invention will be described with reference to FIGS. FIG. 14 is a schematic diagram showing the appearance of the shelf receiver 49 according to the present embodiment. The shelf holder 49 is made of an aluminum material having a good thermal conductivity. In addition, a side heater 45 as a sheathed heater, which is a heating element, is embedded and molded integrally with the shelf receiver 49 inside the shelf receiver 49. The manufacturing method of the shelf holder 49 is expected to have a mass production effect because aluminum is used as a material, and a die casting method or an extrusion molding method that can be manufactured at low cost is adopted. With this manufacturing method, it is possible to arrange a large number of rails 48 on the shelf 49 and to provide the rails 48 at almost arbitrary positions.

  Further, the side heater 45 disposed inside the shelf receiver 49 has a substantially U-shape, but it is preferable that the side heater 45 is disposed so that the U-shaped bent portion 45a is located below the shelf receiver 49 and is integrally formed. . A plurality of rails 48 are arranged on the shelf receiver 49 along the front-rear direction of the housing 1 so that the plurality of shelves 35 can be slidably moved in the direction of the door 14. Instead of the U-shaped bent portion 45a, for example, the side heater 45 may be arranged in a W shape. In short, the side heater 45 only needs to be formed densely in the lower portion of the shelf support 49.

  Next, the operation of the invention according to this embodiment will be described. When a switch (not shown) of the operation unit 21 is turned on and the side heater 45 is energized, the heat of the side heater 45 is quickly transmitted to the shelf receiver 49 with good thermal conductivity, and the rail 48 formed on the shelf receiver 49. To the tray 37 and the shelf network 36. Here, the substantially U-shaped side heater 45 does not generate heat equally, but the U-shaped bent portion 45a generates the strongest heat and becomes high temperature. In other words, in the present embodiment, the lower part of the shelf holder 49 in which the U-shaped bent portion 45a is arranged has the highest temperature. This makes it possible to intensively warm the lower part of the cabinet where the temperature hardly rises.

  On the other hand, although the heating wire is not arranged at the mouth of the side heater 45, the heat generated in the lower part of the cabinet is conducted through the air conduction in the cabinet and the inside of the material of the shelf receiver 49, and the shelf network 36 in the upper stage in the cabinet is also provided. Heated. Therefore, the entire interior can be heated uniformly. The internal temperature management is performed by the temperature sensor 65 and the control device 29 described above.

  As described above, in this embodiment, the food 1 is heated and heat-insulated with the housing 1, the shelf 35 of the housing 1, and the shelf receiver 49 that is provided in the housing 1 and serves as a receiving portion that makes the shelf 35 movable. In the container, the shelf receiver 49 is made of a material having good thermal conductivity, and a side heater 45 as a heating means is formed integrally with the shelf receiver 49.

  In this case, the rail 48 for accommodating the shelf 35 can be arrange | positioned in the substantially arbitrary positions of the shelf holder 49, and the number of the shelf 35 can be increased / decreased according to the height of the goods to display. Further, since the thermal conductivity of the shelf holder 49 is good, heat can be transferred to the shelf 35 efficiently and without temperature unevenness. Further, by forming the side heater 45 integrally with the shelf holder 49, the temperature of the side heater 45 itself can be made uniform, and local heat generation can be prevented. Therefore, the life of the side heater 45 can be extended.

  Particularly in the present embodiment, the shelf holder 49 is formed by extrusion molding of aluminum. That is, since the shelf holder 49 is formed by extrusion molding of aluminum, the shelf holder 49 can be manufactured at low cost. Moreover, heat transfer can be performed efficiently and without temperature unevenness to the shelf 35 in the housing 1 by aluminum having good thermal conductivity.

  Further, in this embodiment, the side heaters 45 are densely provided below the shelf supports 49. In this case, since the side heaters 45 are densely provided below the shelf receiver 49, particularly the lower portion of the shelf receiver 49 generates heat most strongly and becomes high temperature. Accordingly, the entire product can be heated in a state where there is less temperature unevenness by heating the lower portion of the shelf holder 49 where the temperature is difficult to rise to a high temperature.
