Description

  The present invention relates to a kitchen air treatment device for treating exhaust gas generated from cooking means that is installed in a kitchen such as a restaurant and cooks ingredients.

  Traditionally, kitchens such as hotels, restaurants, and fast food restaurants have been cooking food using a fryer or griddle. Steam or steam (hereinafter referred to as exhaust) containing a lot of moisture and odor rises or scatters from these cookers. Conventionally, a hood is placed above the cooker and is generated from the cooker. Exhaust gas was collected in a hood by a blower and discharged to the outside (see, for example, Patent Document 1). Then, air was supplied from the outside to ventilate the kitchen to maintain the worker's working environment.

  However, especially in restaurants and fast food restaurants that open in underground shopping malls, it may be difficult to discharge the exhaust from the cooker to the outside due to the structure of the building. In such a case, the kitchen is filled with moisture and odors. However, there was a problem that the working environment deteriorated.

Therefore, conventionally, a kitchen air treatment apparatus having a dehumidifying means for removing moisture in the exhaust gas generated from the cooker has been developed. This kitchen air treatment device is installed above the cooker, supplies exhaust from the cooker to a cooler constituting dehumidification means, and discharges the exhaust after dehumidification into the kitchen.

  A drain receiver 32 is provided below the cooler 13 at the lower back of the heat insulating box 12. The drain receiver 32 allows water received in the drain receiver 32 to be discharged to the outside. A drain hose 33 for discharging is connected.

  In the heat insulating box 12 on the upper side of the heater 14, the blower 7 for supplying the exhaust in the dehumidifying duct 17 into the deodorizing duct 18 is housed and installed. The blower 7 is connected to the control device. The deodorizer 9 is housed and installed in the front side of the heat insulating box 12, that is, in the deodorizing duct 18. The deodorizer 9 includes, for example, a plurality of porous deodorizing filters 9A containing, for example, activated carbon molded in a substantially V shape, and each deodorizing filter 9A can be inserted and removed from the front. Each deodorizing filter 9A is assumed to be independently replaceable.

  In addition, a partition wall 22 is provided on the front surface of the heat insulating box 12 to seal the front opening in an openable and closable manner. An exhaust communication portion 28 is formed below the partition wall 22 so as to correspond to the lower side of the deodorizer 9 of the deodorizing duct 18 formed in the heat insulating box 12.

  Furthermore, a door 2 is provided in front of the partition wall 22 so as to open and close the front of the air treatment unit 1 located at the upper part of the exterior case 4. The door 2 is hollow inside, and an exhaust duct 25 is formed in the door 2. A plurality of exhaust ports 26 are formed in the upper front portion of the door 2, and the exhaust in the heat insulation box 12 is exhausted through the exhaust communication portion 28 of the partition wall 22 in the lower rear portion of the door 2. A suction port 27 for flowing into the duct 25 is formed. At this time, a packing 29 as a seal member is provided on the rear surface of the door 2 or the front surface of the partition wall 22 and the peripheral portion of the suction port 27 in a state where the door 2 is closed. And the packing 30 for sealing the peripheral part of the exhaust communication part 28 is provided.

  Thus, when replacing the deodorizing filter 9A in the deodorizing duct 18, the door 2 is opened and the partition wall 22 is opened, so that the deodorizing filter 9A can be easily replaced from the front of the heat insulating box 12. Can do. Therefore, the maintenance workability of the deodorizing filter 9A is improved and the convenience is improved.

  On the other hand, an intake port 19 is formed on the back side of the hood portion 4D (the upper back side of the fryer 5) located at the upper portion of the work area 4C and faces the work area 4C. A grease filter (oil removing means) 20 is attached which is positioned from the front end to the rear end of the dehumidifying duct 17 and is inclined downward from the front to the rear. The grease filter 20 has a net shape for adhering and removing oil mist. It is assumed that an oil receiver 34 for receiving oil (oil content) attached to the grease filter 20 is provided at the lower end of the grease filter 20.

  A suction port 21 is formed in the lower part of the dehumidifying duct 17 at a position corresponding to the upper side of the intake port 19 and in front of the drain receiver 32.

  On the other hand, an illumination (fluorescent lamp) 38 is attached to the hood portion 4D of the work area 4C. It is assumed that a translucent illumination cover 39 covered with titanium oxide is provided below the illumination 38 so as to cover the lower surface of the illumination 38.

  In FIG. 1, reference numeral 40 denotes a dehumidifying duct 17 and a deodorizing part that sequentially reach the exhaust communication part 28 through the cooler 13, the heat storage plate 41, the heater 14, the blower 7 and the deodorizer 9 in the heat insulating box 12. This is a fan casing for forming the duct 18 for use.

  Next, the operation of the cooking apparatus S with the above configuration will be described. When the compressor 10 and the blower 7 of the cooling device 6 are operated by the control device, the heater 14 exhibits a heating action, the cooler 13 exhibits a cooling action, and the work space 4C of the cooking apparatus S is provided. The generated exhaust gas is sucked into the dehumidifying duct 17 in the heat insulating box 12 from the suction port 21 through the grease filter 20, and the cooler 13, the heat storage plate 41, the heater 14, the blower 7, and the deodorizing duct 18. A flow of air that passes through the deodorizer 9 and the exhaust duct 25 in the door 2 and is discharged from the cooking device S through the exhaust port 26 is formed.

  On the other hand, exhaust gas containing a large amount of moisture (steam), oil mist, and odor rises from the fryer 5 toward the hood portion 4D of the work area 4C and is sucked into the intake port 21 on the upper back side. The oil mist in the exhaust sucked into the intake port 21 is adhered and removed in the process of passing through the grease filter 20. The oil (oil component) adhering to the grease filter 20 is collected in an oil receiver 34 attached to the lower end of the grease filter 20 and discarded.

  The exhaust gas that has passed through the grease filter 20 as described above is sucked into the dehumidifying duct 17 of the heat insulating box 12 from the suction port 21 and eventually reaches the cooler 13. Since the exhaust gas that has reached the cooler 13 is cooled while passing through the cooler 13, moisture (water) contained in the exhaust gas becomes dew and adheres to the surface of the cooler 13. As a result, the exhaust is dehumidified. The exhaust gas adhering to the cooler 13 is received by the drain receiver 32 and discarded to the outside through the drain hose 33.

  Here, when cooking load decreases, for example, when cooking in the fryer 5 is temporarily stopped, the temperature and humidity of the exhaust gas reaching the cooler 13 are lower than during cooking. On the other hand, since the cooling action in the cooler 13 is continuously generated, surplus cold heat that is not used in the dehumidification process of the exhaust gas is stored in the cool storage agent of the heat storage plate 41 disposed on the air downstream side of the cooler 13. The The cold stored in the heat storage plate 41 exhibits a cooling action as an aid to the cooler 13 in the process of exhaust passing between the heat storage plates 41 when cooking is resumed.

  Thereby, the cool heat from the cooler 13 generated excessively at the time of non-cooking is effectively stored in the cold storage agent and used at the time of resuming cooking, so that effective use of the cold heat at the time of non-cooking can be achieved. Therefore, since the load applied to the cooling device 6 can be reduced, the cooling device 6 can be reduced in size, and the cost can be reduced. Further, by reducing the size of the cooling device 6, waste heat and noise from the compressor 10 and the like can be reduced, and the use environment can be improved. In addition, since the cool storage agent is enclosed in the plate or the tube arranged to allow the air flow as described above, the inconvenience of hindering the air flow of the exhaust gas passing through the dehumidification duct 17 is avoided. be able to.

  The exhaust gas after being dehumidified by the cooler 13 and passing through the heat storage plate 41 reaches the heater 14 and is heated in the process of passing through the heater 14, so that the relative humidity of the exhaust gas decreases. The exhaust gas with reduced relative humidity reaches the deodorizer 9 in the deodorizing duct 18 through the blower 7, and the odor components contained in the exhaust gas are adsorbed in the process of passing through the deodorizing filter 9A. The exhaust gas that has passed through the deodorizer 9 is smoothly fed into the exhaust duct 25 by the exhaust communication portion 28 with the door 2 closed. The exhaust gas flowing into the exhaust duct 25 rises in the exhaust duct 25 and is finally blown out from the exhaust port 26 to the outside of the device S (inside the kitchen).

  In this way, in the cooking apparatus S of the present embodiment, individual circulation ventilation is performed in which the exhaust from the fryer 5 is sucked, dehumidified by the cooler 13 and discharged into the kitchen. Even in an installation situation where exhaust cannot be discharged outside the kitchen, the kitchen will not be filled with moisture. Moreover, since the odor component contained in the steam rising from the fryer 5 is also removed at this time, it is also deodorized at this stage.

  And since exhaust_gas | exhaustion is sent to the duct 18 for deodorization provided with the deodorizer 9, the odor produced when cooking with a fryer 5 or a griddle like an Example can be removed with this deodorizer 9. FIG. The work environment in the kitchen can be further improved.

  Further, a heater 14 is arranged between the deodorizer 9 on the downstream side of the air of the cooler 13, and the low-temperature exhaust gas after moisture is condensed and adhered to the surface of the cooler 13 is heated by the heater 14. Therefore, the exhaust gas having a lower relative humidity is supplied to the deodorizer 9. As a result, it is possible to avoid the inconvenience that moisture enters the deodorizer 9 made of porous activated carbon and the deodorizing action is lowered due to moisture.

  Next, another embodiment of the present invention will be described with reference to FIG. FIG. 3 shows a partially enlarged view of a cooking apparatus S as another embodiment. In addition, what is attached | subjected with the code | symbol similar to FIG. 2 in a figure shall show the same effect. In the cooking apparatus S according to this embodiment, instead of the heat storage plate 41 in the above embodiment, a tube 42 in which a cool storage agent is sealed in a fin-and-tube cooler 13 is provided.

  As a result, when the cooking load is reduced, such as when cooking in the fryer 5 is temporarily stopped, surplus cold heat released from the cooler 13 that is not used for the dehumidification treatment of the exhaust is disposed in the cooler 13. The stored cold storage agent is stored in a sealed tube 42. The cold heat stored in the tube 42 in which the cool storage agent is sealed exerts a cooling action as an auxiliary to the cooler 13 in the process in which the exhaust passes through the cooler 13 when cooking is resumed.

  Therefore, also in the Example which concerns, the effective use of the cold at the time of non-cooking can be aimed at by storing the cold heat from the cooler 13 which arises excessively at the time of non-cooking in a cool storage agent, and using at the time of resuming cooking. become able to. Therefore, since the load applied to the cooling device 6 can be reduced, the cooling device 6 can be reduced in size, and the cost can be reduced. Further, by reducing the size of the cooling device 6, waste heat and noise from the compressor 10 and the like can be reduced, and the use environment can be improved.

  In particular, in the embodiment, the tube 42 in which the cool storage agent is sealed is integrated by the fin together with the tube in which the refrigerant constituting the cooler 13 is sealed, so that the cold heat can be smoothly transmitted, The mounting workability of the cooler 13 can be simplified.

  Next, another embodiment of the present invention will be described with reference to FIGS. 4 is a partially enlarged view of a cooking apparatus S as another embodiment, FIG. 5 is a front view of the cooler 13 of FIG. 4, FIG. 6 is a right side view of the cooler 13 of FIG. The left view of the cooler 13 of FIG. 4 is shown. In addition, what is attached | subjected with the code | symbol similar to FIG. 2 in a figure shall show the same effect. In the cooking apparatus S according to this embodiment, a heat pipe 43 is provided in the fin-and-tube type cooler 13 instead of the heat storage plate 41 in the above embodiment.

  The heat pipe 43 seals the tube on the air inlet side and the tube on the outlet side of the fin-and-tube cooler 13 in communication with each other, and encloses an amount of working refrigerant in which air / liquid can coexist. Configured.

  Thereby, the air having the highest temperature and the highest humidity in the exhaust gas can be cooled and dehumidified by the cooling action of the refrigerant stored in the heat pipe 43 on the downstream side of the air. Then, the refrigerant vaporized by the endothermic action in the heat pipe 43 on the downstream side of the air moves to the upstream side of the heat pipe 43 and is cooled by the cooling action of the cooler 13 in the upper part of the cooler 13 to dissipate heat and liquefy. Then, circulation that flows down to the heat pipe 43 on the downstream side of the air is performed. Therefore, in addition to the cooling action in the refrigerant piping constituting the cooler 13, a high cooling effect can be obtained by the heat pipe 43 configured to communicate with the air downstream side and the air upstream side of the cooler 13. Become.

  In addition, when cooking load is reduced, such as when cooking in the fryer 5 is temporarily stopped, excess cold heat released from the cooler 13 that is not used for exhaust dehumidification processing is used to cool the refrigerant in the heat pipe 43. It is possible to obtain a cold storage effect.

  As a result, it is possible to effectively use the cold heat, and the load applied to the cooling device 6 can be reduced. Therefore, the cooling device 6 can be reduced in size, and the cost can be reduced. Further, by reducing the size of the cooling device 6, waste heat and noise from the compressor 10 and the like can be reduced, and the use environment can be improved.

  In the present embodiment, the cooking apparatus S in which the fryer 5 as the cooking means and the air treatment unit 1 are integrally formed has been described as an example. However, the air treatment unit 1 is provided separately from the cooking means. Even when configured as an air treatment device, the same effect is obtained.
