Description

The present invention relates to a temperature / humidity control cabinet capable of controlling the temperature and humidity of a storage chamber. Examples of the temperature / humidity control cabinet include a dough conditioner having a function of freezing or refrigerating the bread dough stored in the storage chamber and performing thawing, preheating, and fermentation of the bread dough.

In the field of storage and showcases, including temperature and humidity control cabinets equipped with a refrigeration system for cooling the air in the storage room, drainage such as dew condensation water and defrost water generated by the evaporators that make up the refrigeration system is discharged outside the refrigerator. A drain trap is provided at the discharge port for discharge. Since food waste that has fallen to the bottom of the storage chamber flows into the drain trap together with the drainage, the drain trap needs to be disassembled and cleaned regularly. Patent Document 1 discloses a drain trap that can suppress clogging due to food waste and extend the cleaning interval.

The drain trap of Patent Document 1 includes a drain pipe (inflow pipe) into which drainage flows, and a water storage container (water storage container) having a drain outlet (outflow pipe) on the side surface, and the lower end of the drain pipe is provided. The trap structure is constructed by locating it higher than the bottom surface of the water reservoir and lower than the outlet. Then, by forming the bottom surface of the water storage container so as to incline downward toward the outlet side, food waste (garbage, etc.) flowing into the water storage container from the drain pipe flows along the inclination of the water storage container. I try to collect it on the exit side.

In the drain trap of Patent Document 1, by collecting the food waste on the outlet side, it is possible to prevent the food waste from accumulating under the drain pipe, so that the lower end of the drain pipe is blocked with the food waste to form the drain trap. It is possible to suppress clogging and extend the cleaning interval. However, the time and effort required for regular disassembly and cleaning remains the same, and if cleaning is forgotten, the drain trap may eventually become clogged and drainage may flow back into the storage chamber. Further, if food waste stays in the drain trap for a long period of time, the food waste will spoil and germs will propagate, and the inside of the storage chamber cannot be kept in a hygienic state.

The present invention provides a temperature / humidity control cabinet that can discharge food waste that has flowed into a water storage container to the outside of a drain trap, eliminate the trouble of cleaning, and keep the inside of the storage chamber in a hygienic state. The purpose is to do.

The lower end is provided so as to face the lower wall 42 through a gap, and the inflow cylinder 45 for guiding the drainage to the water storage container 44 and the outflow cylinder 46 provided on the peripheral wall 43 for discharging the drainage are provided. Then, a water injection pipe 57 provided with a supply valve 58 for opening and closing the pipeline is provided between the water supply pipe 18 and the water storage container 44, and the water of the water supply pipe 18 is injected into the water storage container 44 of the drain trap 40. It is characterized in that it is configured to be.

The peripheral wall 43 of the water storage container 44 is formed in a cylindrical shape, and the peripheral wall 43 is provided with a water injection cylinder 47 to which the water injection pipe 57 is connected. In a plan view, the outflow cylinder 46 and the water injection cylinder 47 are arranged at positions that are point-symmetrical with the center of the water storage container 44 as the center of symmetry.

The lower end position of the opening of the water injection cylinder 47 is arranged above the lower end position of the opening of the outflow cylinder 46.

The water injection pipe 57 includes a first water injection pipe 57A on the upstream side where a supply valve 58 is provided, and a second water injection pipe 57B on the downstream side. Both water injection pipes 57A and 57B are connected so that the upstream end portion 57D of the second water injection pipe 57B covers the downstream end portion 57C of the first water injection pipe 57A extending vertically. The outer diameter d1 of the downstream end 57C of the first water injection pipe 57A is set smaller than the inner diameter d2 of the upstream end 57D of the second water injection pipe 57B, and a gap is set between the two water injection pipes 57A and 57B.

It was configured to be injected into 40 water storage containers 44. According to such a temperature / humidity control storage, the water of the water supply pipe 18 can be injected into the water storage container 44 by opening the supply valve 58 as needed, so that the injected water causes food waste accumulated inside the water storage container 44. Can be flushed out from the outflow cylinder 46 together with the drainage. Therefore, according to the present invention, the inside of the water storage container 44 can be cleaned simply by opening the supply valve 58 without disassembling the drain trap 40, so that the labor of cleaning can be eliminated and the inside of the storage chamber 1 can be further cleaned. Can be kept in a hygienic condition. Further, since the water supply pipe 18 of the existing humidifying device 7 and the drain trap 40 are only connected by the water injection pipe 57 provided with the supply valve 58, the drain trap 40 is connected to the temperature / humidity control cabinet without major structural changes. There is also an advantage that it can be equipped with a cleaning structure.

When the peripheral wall 43 of the water storage container 44 is formed in a cylindrical shape and the water injection cylinder 47 to which the water injection pipe 57 is connected is provided, the water injected from the water injection cylinder 47 into the water storage container 44 is stored. It can be diffused toward the center of the container 44, and after passing through the center, can be flowed so as to converge on the opposite side of the water injection cylinder 47. Further, in a plan view, when the outflow cylinder 46 and the water injection cylinder 47 are arranged at positions that are point-symmetrical with the center of the water storage container 44 as the center of symmetry, the water injection cylinder 47 is injected into the water storage container 44 and diffuses.

Therefore, since the injected water can be prevented from flowing back to the water injection pipe 57 side, the food waste accumulated in the water storage container 44 can be more accurately discharged from the outflow cylinder 46.

In the first water injection pipe 57A and the second water injection pipe 57B constituting the water injection pipe 57, the downstream end 57C of the first water injection pipe 57A extending vertically is covered with the upstream end 57D of the second water injection pipe 57B. The outer diameter d1 of the downstream end 57C of the first water injection pipe 57A is set to be smaller than the inner diameter d2 of the upstream end 57D of the second water injection pipe 57B. -A gap is formed between 57B. According to this, even if the water supplied from the first water injection pipe 57A or the drainage in the water storage container 44 flows back through the second water injection pipe 57B, the backflowed water is a gap between the connecting portions of both water injection pipes 57A and 57B. Since it overflows to the outside of the water injection pipe 57, it is possible to prevent dirty water from flowing back to the first water injection pipe 57A. Therefore, it is possible to prevent the water supply pipe 18 of the humidifying device 7 to which the first water injection pipe 57A is connected from being contaminated, and the humidifying device 7 can be maintained in a hygienic state.

A pair of front and rear shelf columns 32 are mounted on the left and right side walls of the storage chamber 1A, and a plurality of shelf boards 33 are supported by these shelf columns 32 in a multi-stage manner. A heat-resistant tray on which a large number of bread doughs are placed is placed on the shelf board 33. Since the configuration of the storage chamber 1B is the same as the configuration of the storage chamber 1A, the same members are designated by the same reference numerals and the description thereof will be omitted.

An upper water collecting portion 34 is provided near the upper surface of the intermediate wall 4 constituting the bottom surface of the storage chamber 1A, and the bottom surface excluding the upper water collecting portion 34 is inclined downward toward the upper water collecting portion 34. ing. Similarly, a lower water collecting portion 35 is provided near the upper surface of the bottom wall (bottom) 2A of the main body case 2 constituting the bottom surface of the storage chamber 1B, and the bottom surface excluding the lower water collecting portion 35 is below. It slopes down toward the water collecting part 35. Condensed water generated by the evaporator 13, defrosted water, and drainage of water sprayed from the spray nozzle 16 and not evaporated are collected in the upper water collecting part 34 and the lower water collecting part 35, and then in the main body case 2. It is discharged to the outside from the drain port 36 provided on the bottom wall 2A. The drainage collected by the upper water collecting part 34 is moved to the lower water collecting part 35 via the flow pipe 37 and then discharged from the drain port 36.

A drain trap 40 is connected to the drain port 36 in order to prevent external air and pests from entering the storage chamber 1B from the drain port 36. The drain trap 40 includes a water storage container 44 including a disk-shaped upper wall 41 and a lower lid (lower wall) 42, and a cylindrical peripheral wall 43 connecting the peripheral edges of the upper wall 41 and the lower lid 42. A round pipe-shaped inflow cylinder 45 that penetrates the upper wall 41 and has its lower end facing the lower lid 42 through a gap, and a round pipe-shaped outflow cylinder 46 that is provided on the peripheral wall 43 so as to extend in the horizontal direction. And a water injection cylinder 47. The drain trap 40 is fixed to the bottom wall 2A of the main body case 2 by inserting and mounting the upper end of the inflow cylinder 45 into the mounting recess 48 formed at the lower end of the drain port 36. A drain hose 49 that guides the drainage discharged from the drainage cylinder 46 to the drainage pit is inserted and attached to the outflow cylinder 46.

In the plan view of the drain trap 40 shown in FIG. 3, the inflow cylinder 45 is arranged so that its central axis coincides with the center of the water storage container 44. The outflow cylinder 46 and the water injection cylinder 47 are arranged at positions where their central axes are oriented along the radial direction of the water storage container 44 and are point-symmetrical with the center of the water storage container 44 as the center of symmetry. Further, in the side view of the drain trap 40 shown in FIG. 2, the lower end position of the opening of the water injection cylinder 47 is arranged above the lower end position of the opening of the outflow cylinder 46, and the lower end position of the opening of the outflow cylinder 46 is the inflow cylinder. It is arranged above the lower end position of the opening of 45.

The upper wall 41 and the peripheral wall 43, the inflow cylinder 45, the outflow cylinder 46, and the water injection cylinder 47 constituting the water storage container 44 are integrally formed, and the lower lid 42 constituting the water storage container 44 can be attached to and detached from the peripheral wall 43. It is attached to. Specifically, the lower lid 42 is a disk formed to have a diameter larger than the outer diameter of the peripheral wall 43, and includes a tubular portion 51 that circulates upward from the peripheral edge portion thereof. A female threaded portion 52 is formed on the inner surface of the tubular portion 51, and the female threaded portion 52 can be screwed into the male threaded portion 53 formed on the lower peripheral peripheral surface of the peripheral wall 43. The lower lid 42 in the mounted state can be separated from the peripheral wall 43 by unscrewing the male and female screw portions 52 and 53 by rotating the lower lid 42 in a counterclockwise direction in a plan view. On the contrary, the lower lid 42 in the separated state can be attached to the peripheral wall 43 by screwing the male and female screw portions 52 and 53 by rotating the lower lid 42 in the clockwise direction in a plan view. In FIG. 2, reference numeral 54 is a seal ring interposed between the lower end surface of the peripheral wall 43 and the upper surface of the lower lid 42, and water leaks from the screwed portion of the male and female screw portions 52 and 53 at the seal ring 54. It prevents it from coming out. By configuring the drain trap 40 so that the lower lid 42 can be attached to and detached from the peripheral wall 43 in this way, even if food waste is stuck to the inner surface of the water storage container 44, the stuck food waste can be easily removed. Can be removed.

The drainage that has flowed into the drainage port 36 is guided by the inflow cylinder 45 and stored in the water storage container 44. When the drainage stored in the water storage container 44 exceeds the lower end position of the opening of the outflow cylinder 46, the excess drainage is discharged from the outflow cylinder 46. In this state, the lower end of the inflow cylinder 45 is immersed in the drainage stored in the water storage container 44, the drainage in the water storage container 44 functions as a trap, and air and pests invade the storage chamber 1B from the outside. I'm blocking you from doing it.

Small pieces of bread dough and pieces of bread after baking (hereinafter simply referred to as "food waste") fall on the bottom of the storage chambers 1A and 1B when the heat-resistant tray is taken in and out. It is inevitable that food waste will flow in. Therefore, in the deconditioner of the present embodiment, a structure for flushing out the food waste that has flowed into and accumulated in the water storage container 44 is provided so that the inside of the water storage container 44 can be cleaned without removing the lower lid 42. It is configured. Specifically, a water injection pipe 57 is provided between the humidifying device 7 and the drain trap 40, one end of which is connected to the water supply pipe 18 and the other end of which is connected to the water storage container 44. By controlling the opening and closing of the supply valve 58 formed of the solenoid valve provided in the unit by the control unit 29, the water for cleaning is supplied from the water supply pipe 18 to the drain trap 40.

As shown in FIGS. 1 and 5, the water injection pipe 57 is divided into a first water injection pipe 57A on the upstream side extending vertically and a second water injection pipe 57B on the downstream side bent in an L shape. 1 A supply valve 58 is arranged in a water injection pipe 57A. The first water injection pipe 57A is made of a copper pipe, and its upstream end is connected to the main pipe 18A of the water supply pipe 18. The second water injection pipe 57B is made of vinyl chloride, and its downstream end is connected to the water injection cylinder 47 of the drain trap 40 via the socket 59. The transverse portion of the second water injection pipe 57B arranged below the bottom wall 2A of the main body case 2 is slightly inclined downward toward the drain trap 40. The downstream end of the first water injection pipe 57A and the upstream end of the second water injection pipe 57B are connected so that the second water injection pipe 57B covers the first water injection pipe 57A. Specifically, as shown in FIG. 4, the pipe outer diameter d1 of the downstream end portion 57C of the first water injection pipe 57A is set to be smaller than the pipe inner diameter d2 of the upstream side end portion 57D of the second water injection pipe 57B. (D1 <d2), both water injection pipes 57A and 57B are fixed to the main body case 2 with the bracket 60 with the downstream end 57C inserted into the upstream end 57D. It is connected with a gap formed between them.

In the cleaning operation of the drain trap 40, the supply valve 58 is opened, and after a predetermined time has elapsed, the supply valve 58 is closed. When the supply valve 58 is opened, the water discharged from the lower end of the first water injection pipe 57A is received at the upper end of the second water injection pipe 57B, flows through the second water injection pipe 57B, and then passes through the water injection cylinder 47 to the water storage container. It is injected into 44. The injected water flows to the outflow cylinder 46 side while flushing the food waste staying in the water storage container 44, and is discharged from the outflow cylinder 46 side together with the food waste. When the supply valve 58 is closed after injecting water into the water storage container 44 for a predetermined time (for example, 10 seconds), the cleaning of the drain trap 40 is completed.

The flow of water injected from the water injection cylinder 47 into the water storage container 44 diffuses in the water storage container 44 and then converges to reach the outflow cylinder 46. Specifically, the injected water flows while diffusing along the left and right inner surfaces of the lower lid 42 and the water storage container 44, and reaches the front-rear center of the water storage container 44. When it exceeds the center of the front and rear of the water storage container 44, it flows while converging along the left and right inner surfaces of the lower lid 42 and the water storage container 44, and after converging, it is discharged from the outflow cylinder 46. In this embodiment, the outflow cylinder 46 is arranged at a position where the diffused water converges due to the positional relationship between the outflow cylinder 46 and the water injection cylinder 47, which are arranged at points symmetrical with respect to the center of the water storage container 44. Therefore, the water smoothly moves in the water storage container 44 without stagnation of its flow and reaches from the water injection cylinder 47 to the outflow cylinder 46.

As described above, the entire deconditioner including the refrigerating device 6, the humidifying device 7, the first water supply valve 19A, the second water supply valve 19B, the supply valve 58, and the like is controlled by the control unit 29. The control unit 29 maintains the temperatures of the storage chambers 1A and 1B at the freezing temperature or the refrigerating temperature, and freezes or refrigerates the stored bread dough, and defrosts the frozen bread dough. Preheating operation to preheat the thawed or refrigerated bread dough by maintaining the temperature of each storage room 1A / 1B at the preheating temperature, and optimalizing the temperature and humidity of each storage room 1A / 1B for fermentation. It is configured so that various operating conditions such as a fermentation operation for fermenting the preheated bread dough can be registered and executed in advance. Further, the control unit 29 includes an independent operation mode in which each of these operations is individually executed, and an automatic operation mode in which the storage operation, the thawing operation, the preheating operation, and the fermentation operation are executed in order. The independent operation mode and the automatic operation mode can be executed by an operation panel (not shown) provided in front of the deconditioner. In the automatic execution mode, when the storage operation is executed at the refrigerating temperature, the thawing operation is omitted.

The cleaning of the drain trap 40 can be performed at the timing of the pre-stage or the post-stage of the operation in the independent operation mode, or the pre-stage or the post-stage of the operation in any of the automatic operation modes. In the de conditioner, the manufacturer recommends that the user clean the inside of the storage 1 before the independent operation mode or the automatic operation mode. Therefore, there is a possibility that food waste may remain in the water storage container 44 after cleaning. Therefore, in this embodiment, the drain trap 40 is cleaned before the operation in the independent operation mode and before the storage operation in the automatic operation mode. Further, in this embodiment, a cleaning mode for executing the cleaning operation of the drain trap 40 is provided, and when the cleaning mode is executed, the cleaning operation of the drain trap 40 is executed.

As described above, in the deconditioner of the present embodiment, a water injection pipe 57 provided with a supply valve 58 for opening and closing the pipeline is provided between the water supply pipe 18 and the water storage container 44, and the water supply pipe 18 is provided. Water was configured to be injected into the water storage container 44 of the drain trap 40. According to such a de-conditioner, the water of the water supply pipe 18 can be injected into the water storage container 44 by opening the supply valve 58 as needed, so that the injected water flushes out the food waste accumulated inside the water storage container 44. , Can be discharged together with the drainage from the outflow cylinder 46. Therefore, since the inside of the water storage container 44 can be cleaned simply by opening the supply valve 58 without disassembling the drain trap 40, the labor of cleaning can be eliminated and the inside of the storage chamber 1 is kept in a hygienic state. it can. Further, since the water supply pipe 18 of the existing humidifying device 7 and the drain trap 40 are only connected by the water injection pipe 57 provided with the supply valve 58, the drain trap 40 is connected to the temperature / humidity control cabinet without major structural changes. There is also an advantage that it can be equipped with a cleaning structure.

Since the peripheral wall 43 of the water storage container 44 is formed in a cylindrical shape and the water injection cylinder 47 to which the water injection pipe 57 is connected is provided on the peripheral wall 43, the water injected from the water injection cylinder 47 into the water storage container 44 is collected from the water storage container 44. It can be diffused toward the center, crossed the center, and then flowed so as to converge on the opposite side of the water injection cylinder 47. Further, in a plan view, the outflow cylinder 46 and the water injection cylinder 47 are arranged at positions that are point-symmetrical with the center of the water storage container 44 as the center of symmetry. The water can be smoothly flowed to the outflow cylinder 46, and the food waste accumulated in the water storage container 44 can be accurately discharged from the outflow cylinder 46.

Since the lower end position of the opening of the water injection cylinder 47 is arranged above the lower end position of the opening of the outflow cylinder 46, all the water flowing from the water injection cylinder 47 into the water storage container 44 is discharged from the outflow cylinder 46. Therefore, since the injected water can be prevented from flowing back to the water injection pipe 57 side, the food waste accumulated in the water storage container 44 can be more accurately discharged from the outflow cylinder 46.

The outer diameter d1 of the downstream end 57C of the first water injection pipe 57A is set smaller than the inner diameter d2 of the upstream end 57D of the second water injection pipe 57B, and a gap is set between the two water injection pipes 57A and 57B. Even if the water supplied from the first water injection pipe 57A or the drainage in the water storage container 44 flows back through the second water injection pipe 57B, the backflow water is still in the gap between the connecting portions of both water injection pipes 57A and 57B. Since it overflows to the outside of the water injection pipe 57, it is possible to prevent dirty water from flowing back to the first water injection pipe 57A. Therefore, it is possible to prevent the water supply pipe 18 of the humidifying device 7 to which the first water injection pipe 57A is connected from being contaminated, and the humidifying device 7 can be maintained in a hygienic state.
