Description

[Detailed description of the invention] This invention produces and stores ice blocks using an ice maker, cools and stores cooling water using a water chiller, and adds τ amount of cold water to the cooling water close to J6j5 according to the ambient temperature water number. We are able to supply ice making and water chillers & related products.

□ ゛In fields that require a large amount of cold water, for example in industries that handle perishable tofu, cold water produced in a water cooler is used for everything from soaking beans to replacing water for products and packaging. .

□For example, the amount of water used when replacing the product will of course vary depending on the scale of the tofu manufacturing equipment, and in medium-sized equipment, cold water with a water temperature of 15°C or less is used continuously for about 1 hour at a rate of 15% per minute.
By the way, unless you use a large-capacity water chiller, you can carefully drink a large amount of cold water like this.
``L, Kashi: In general, the tofu industry is not good, especially in places with good locations.''If you are a retailer who has to set up a two-store store, you will need to install eel manufacturing equipment, which originally requires a large installation space. In many cases, it is impossible to install a large-capacity, ie, large-sized, water cooler, and the reality is that it is difficult to supply cold water.

In addition, as is well known in the tofu industry, the raw beans are soaked by the evening of the previous day, and the next day they are ground from Hayamisaki.
It is normal to carry out various tasks such as heating, filtering, hardening, molding, etc., and then to change the water of the product, that is, to expose it to water until around 7 to 8 a.m. Under such extreme working conditions, it is difficult to keep up with the work. Because of this, improvements have been requested.

Therefore, in consideration of these circumstances, this rate has been designed to provide a cold water tank that can supply a large amount of cold water without requiring a wide installation or space, and does not require the user to spend an extra □ time. The following examples are shown in the attached drawings. 4. S-mo explanation name.

Figure 1 shows the rate of increase of 5. ;given name! The main entrance structure shows a vertical cross-section of the frozen ice zelkova, □ Ice making mechanism section 2 that makes up ice 1, cold water mechanism section 3 that makes cooling water, and stocker 4 that stores ice and cooling water. Equipped with.

, the power to adopt O4 Kochi's seeds and structure as gJ4 Ice Keyaki Club 2! , □1, Honjo example meyo1. It is preferable to have a large number of ice-making chambers 5 that open downward, and to be cooled by an ice-making evaporator 9, and to have an ice-making shoe shaped like a fountain or water fountain from below in the ice-making chamber 5. It is.

The ice 1 produced by repeating the ice making cycle for a predetermined period of time in the ice making mechanism section 2 is stored in the stocker 4.

□The cold water mechanism part 3 is a well-known double pipe with fins, and has an inner pipe 3a with a harp shell and a four-pipe pipe.
It is provided with an outer tube through which a refrigerant passes or a water-cooling evaporator 3b, and is activated to store cooling water in a stocker 4 after the ice-making mechanism 2 has been operated for a predetermined period of time.

The stocker 4 is surrounded by a suitable heat insulating material 13.

FIG. 2 shows the refrigeration circuits of the ice making mechanism section 2 and the chilled water mechanism section 3.

The refrigeration circuit is compression & lCM. Condenser CO Lucibar 14,
Dryer 15, first electromagnetic valve V1, first expansion valve EV1,
The ice-making evaporators 6 are connected in series to form a closed circuit, and a pipe that bypasses the condenser CO and the first expansion valve EV□ is used to remove ice formed in the ice-making compartment 5. A hot gas valve is provided.

On the other hand, in order to operate the chilled water mechanism section 3, a second solenoid valve V2, a second expansion valve Ev2, and a water cooling valve are connected in parallel to the first solenoid valve v0, the first expansion valve EV, and the ice-making evaporator 6. evaporator (outer tube 3b) is connected.

The first solenoid valve v1 and the second solenoid valve V2 are electrically connected so that when one is open, the other is closed;
It is possible to perform ice making operation and chilled water operation alternately using one compressor fM and one condenser CO.

Therefore, for example, when using this ice-making water cooler in the tofu industry, after soaking the raw beans the day before, the first solenoid valve v1
is opened, the second solenoid valve v2 is closed, and ice making operation is continued for a predetermined time, that is, until several hours before product water change on the next day, to store a large amount of thermal energy in the form of latent heat of the ice in the stocker 4, and then, The first solenoid valve V□ is closed and the second solenoid valve V2 is opened to perform cold water operation, and the cooling water is stored in the same stocker 4.

When replacing water for the product, while continuing the cold water operation, open the discharge valve 16 and replenish, for example, tap water through the pipe 17, so that the low temperature cooling water in the stocker close to 0°C is
It is heated to a predetermined temperature of 0° C. or lower and supplied to a water exchange tank (not shown).

Known automatic temperature control valves may be used for temperature control.

According to this proposal, thermal energy is stored in the form of latent heat in the ice during the night, and ice is produced.Furthermore, after the ice is produced, the same compressor and condenser are used to supply cold water. 1. Can I use the i□ position in a relatively small installation space? It is possible to supply a large amount of cold water, and it requires almost no effort from the user.

Figure 3 shows the electric circuit diagram for controlling the production, ice-cooling machine, φ operation, and rotation according to the present invention. The operation control mode using this electric circuit will be explained with reference to FIGS. 1 to 3, particularly FIG. 3.

In FIG. 3, 1M2 is a 24-hour timer, and has a coil 18 with one end connected to the + side of the power supply and the other end connected to one side, and the set time is manually adjusted by a dial 19.

When the set time is reached, the switch S1 of the timer TM2 switches from the a contact on the electric circuit 2A side of the ice making mechanism section 2 to the b contact on the electric circuit 3A side of the chilled water mechanism section 3.

Connected in series to the coil 18 is a normally open manual changeover switch SW2, and by opening this switch SW2 and connecting the switch to the A contact or B contact side by manual operation of the dial 19, The ice-making water chiller can be operated independently as an ice-making machine or a water chiller.

A switch SW connected in parallel to this timer TM2,
is a known water storage detection switch installed in the illustrated position (FIG. 1) in the stocker 4, and closes when it detects that a predetermined amount of ice has been stored, energizes the heater 20 of the timer TM1, and After an hour, electrical unity and generosity will be disconnected.

The switch SW4 is likely to malfunction and temporarily close due to ice cubes falling from the ice making compartment 5, but a timer TM1 that does not operate unless the closed state continues for a predetermined period of time is provided, so that malfunction can be prevented.

Water cutoff switch SW1 connected in series with timer TM
．． is a pressure switch installed in the conduit 21 (Fig. 2) that supplies tap water to the compressor CO and the chilled water mechanism 3. The pressure switch detects the new condition based on the subsequent pressure difference, closes the conduit, and closes the conduit. Disconnect from power supply.

Therefore, an accident in which the chilled water mechanism section 3 is damaged due to the internal pipe 3a being operated can be prevented.

・Next, we will explain ice making operation and chilled water operation using this control device.

The selector switch S3 is arranged so that it can be selectively connected to the timer switch S2.
When '8 is tilted to the downward position, the ice making tank 7 and the water flIL8 are connected to the A contact side when it is in the position shown in Figure 1.'9.

, . First, the ice-making water is supplied via the solenoid valve Wv to a predetermined water level in the ice-making water tank 7, which is closed when the switch SW3 detects a predetermined water level.

Is the circulation pump PM used during ice making operation? The ice-making water is circulated to the ice-making chamber 5 and gradually frozen, and the unfrozen ice-making water passes through an opening (not shown) in the water tray 8 to the ice-making water tank 7 in a known manner.
Return to

In this state, the switch S□ is connected to the a contact side, so the first solenoid valve V1 is opened, but the second solenoid valve V2
And water supply solenoid valve V3 is closed, and cold water operation is not performed.

Completion of ice making is detected by an ice making completion thermoswitch Th, whose contact Tha is opened to stop operation of the circulation pump PM, and its contact Thb is closed to operate the drive motor.

Therefore, the ice making water tank 7 and the water tray 8 are tilted around the axis 9 by the drive motor AM, the switch S1 is connected to the b contact side, and the hot gas valve HV is energized through the a contact of the switch S2 to remove ice. Start driving.

At the same time, the remaining ice in the ice making water tank 7 is discharged into the drain tray 10, and from the remaining water outlet pipe 12 through the puirta 11 to the stocker 4.
be introduced within.

When hot gas flows into the ice-making evaporator 6 by opening the hot gas valve HV and deicing is completed, the deicing thermo switch R is activated.
h is closed, the drive motor AM is reversed, and the ice-making water tank 7
Then, the water tray 8 is brought back to the raised position, and the ice making mechanism section 2 starts ice making operation again.

The ice 1 removed from the ice making chamber 5 by removal is stored in a stocker.

While repeating such a cycle, when the time set by the timer TM2 is reached, the switch S2 is switched to the b contact on the cold water mechanism section 3 side.

However, as is clear from FIG. 3, the switches S1 and S
2 forms an AND circuit, the time when the cold water operation actually starts is when the water tray 8 reaches the lower position and the switch S1 is connected to the b contact.

11 switch S□
is connected to the B contact, and when the switch S2 is connected to the B contact, the first solenoid valve V1 is closed, the second solenoid valve 2 and the water supply solenoid valve V3 are opened, and water flows through the cold water evaporator 3b. Heat exchange occurs between the refrigerant and the tap water supplied through the pipe line 21, and the cooling water is stored in the stocker 4.

According to the present proposal, even if the timer TM2 reaches the set time and the switch S2 is switched to the chilled water mechanism side, the timing to actually switch to chilled water operation is selected when the tank 7 is tilted downward to separate position, so the chilled water During operation, there is no ice-making water in the ice-making water tank ψ, so there is no need to worry about the water in the ice-making water tank 7 freezing during the winter.

If the water in the ice-making water tank 7 is frozen and the water cooler switches from cold water operation to ice-making operation, the freezing condition in the ice-making chamber 5 will be adversely affected and an unexpected situation will occur. becomes.

Also, when the ice-making water tank 7 tilts downward, the hot gas valve opens as described above, so if the ice-making water cooler is switched to cold water operation at this time, the first solenoid valve V1 opens. Under these conditions, the refrigerant liquid no longer stagnates near the first expansion valve EV1 and the ice-making evaporator 6, and the refrigerant liquid is not sent to the compression & ICM during the next ice-making operation, keeping the compressor CM in an optimal state. It is possible to drive.

In order to change the water of tofu, for example, using an ice-making water cooler having such a fitlJ control device, after soaking the raw beans on the previous day, the 24-hour timer TM2 is set to a predetermined time, that is, the next day: t; Set it to , then power on,
Then, the ice maker and water cooler reaches the predetermined time.

The ice making operation is repeated and ice is stored in the stocker.

When the predetermined time is reached and the ice-making water tank and water tray "yJ" (lower position) are reached, the ice-making water cooler automatically switches to cold spring operation, and enough cooling water is stored together with ice until the start of water testing, and the water is replaced. Cooling water is also supplied inside.

Therefore, according to the present invention, a large amount of cold water can be supplied by an ice-making water cooler that can be installed in a relatively small space by simply turning on and off the power switch according to the set time of the two-instant timer.
