[Detailed description of the invention] Industrial field of application This invention relates to a horizontal refrigerator that uses brine as a cooling medium.More specifically, the invention relates to a horizontal refrigerator that uses brine as a cooling medium. This relates to improvements to horizontal refrigerators.

Conventional technology When storing fresh foods such as fruits, vegetables, meat, and fish (hereinafter referred to as "ingredients") frozen for a long period of time without deteriorating their quality, and when gradually thawing frozen foods, it is generally necessary to keep temperature changes inside the refrigerator in check. keep it low,
At the same time, it is necessary to control and manage the evaporation of moisture from foodstuffs. In order to meet this demand, brine cooling type refrigerators that use antifreeze (hereinafter referred to as "brine") as a cooling medium have been put into practical use.

This type of refrigerator is mainly used for commercial purposes, and one known product form is a horizontal refrigerator in which the cabinet is configured horizontally as shown in FIG. This is a storage compartment 1a that cools and stores ingredients inside a horizontally long box (cabinet) 1.
and a cooling unit section 2 adjacent to the storage compartment 1a.
The top surface of the board is configured as a table board.

Problems to be Solved by the Invention In the conventional horizontal refrigerator mentioned above, the lower part of the cooling unit part 2 is connected to the storage compartment 1 as shown in FIG.
A brine tank 8 is disposed in this protruding space, and a refrigeration system 6 consisting of a compressor, a condenser, etc. is disposed at a portion adjacent to the tank 8 at the bottom of the cooling unit section 2. The structure is designed to be set up. An electrical equipment box 13 equipped with a thermometer, an internal temperature controller, an alarm lamp, etc. is provided above the refrigeration device 6 in the cooling unit section 2, and an electrical equipment box 13 is provided above the protrusion in the storage 1a. , a cooler 17 is disposed to which the brine cooled in the brine tank 8 is circulated and supplied.

In this way, the conventional horizontal refrigerator has a structure in which the lower part of the cooling unit part 2 protrudes toward the storage compartment 1a in order to secure the installation space for the brine tank 8. The internal volume of the warehouse was limited and small, making it difficult to utilize it effectively. Further, since the mounting portion of the cooler 17 is located in a narrow space above the protrusion in the storage 1a, there is a drawback that assembly and maintenance work is difficult. Furthermore, the process of protruding the cooling unit part 2 toward the storage compartment 1a increases the manufacturing process.
It is pointed out that this will lead to an increase in costs. Moreover, an electrical control circuit whose elements are generally heat-sensitive semiconductors and electrical parts is housed in the electrical equipment box 13, and since this electrical equipment box 13 is located above the refrigeration equipment 6, which generates a large amount of heat, it is not affected by the heat. This resulted in problems such as malfunctions and shortened parts life.

Purpose of the invention This invention was proposed in view of the above-mentioned drawbacks inherent in the conventional horizontal refrigerator, and was proposed to suitably solve the problems. An object of the present invention is to provide a brine cooling type horizontal refrigerator configured to facilitate manufacturing and maintenance/inspection.

Further, an L-shaped mounting plate 54 is fixed to the side wall 51b of the brine detection tank 51, and a float switch 55 is mounted on the plate surface extending from the tank opening. This float switch 55 is equipped with a float 55a, and when the brine in the detection tank 51 decreases, the float 55a is lowered and the switch is activated.
When the detection tank 51 is filled with brine and overflows, the float 55a rises and the switch is turned on. Note that instead of providing a float switch, an electrode type switch, pressure type switch, or other mechanical type switch may be used.

Furthermore, if the brine tank 8 is provided with a liquid level gauge 101 based on the principle of a communicating tube, the brine liquid level in the tank 8 can be visually checked from the outside, which is convenient. The liquid level gauge 101 is, for example, a synthetic resin tube (hose) that is transparent and can be bent without deteriorating under low temperature conditions.

is filled. A first cooler 17 through which brine as a cooling medium is circulated is fixedly disposed on the left side of the interior of the storage space defined in the inner box 15 . As this first cooler 17, a fin-and-tube type is preferably adopted, but it may also be a plate type. Inside the refrigerator, there is a cooling duct 18 that is open at the bottom and sealed at the top, as shown in the figure.
is disposed to cover the first cooler 17 in a non-contact manner.

Note that an opening 19 is formed in the cooling duct 18,
The refrigerator air sucked from below the cooling duct 18 by the cold air circulation fan motor FM ₁ 20 disposed in the opening 19 is cooled by exchanging heat with the first cooler 17, and then cooled by the cooling air circulating through the opening 19. It is blown out from the refrigerator and circulated as shown by the solid arrow in FIG. 5 to cool the entire interior of the refrigerator. Further, a defrosting thermometer Th ₁ for detecting the end of defrosting and a heater H ₁ for promoting defrosting are arranged near the first cooler 17, and further below the first cooler 17, a dew pan 21 is provided. The water droplets dripping from the cooler 17 during defrosting are collected and discharged outside the refrigerator.

It is covered in a non-contact manner by a cooling duct 23. An opening 24 is formed in this cooling duct 23, and a fan motor FM ₂ 25 disposed in this opening 24 circulates the air inside the refrigerator as shown by the broken line arrow in FIG. 5 to cool the entire inside of the refrigerator. It's becoming like that. A defrosting thermometer is installed near the second cooler 22 to detect the end of defrosting.

FIG. 5 is a schematic system diagram showing each pipe system of a refrigerant-based refrigeration circuit and a brine circulation circuit. In the figure, refrigerant gas compressed by a compressor 60 is condensed and liquefied in a condenser 7, dehumidified in a dryer 62, and then branched into a first solenoid valve V ₁ and a second solenoid valve V ₂ . . The liquefied refrigerant that passed through the first solenoid valve _V1 is
The pressure is reduced in the capillary reach tube 63, and the brine is evaporated in the third cooler 47 disposed in the brine tank 8, exchanging heat with the brine to cool the brine. The evaporated refrigerant returns to the compressor 60 via the suction pipe 64.

In addition, the liquefied refrigerant that has passed through the second solenoid valve V ₂ is
The pressure is reduced in the capillary reach tube 65, and the air is evaporated in the second cooler 22, exchanging heat with the air inside the refrigerator, thereby cooling the air inside the refrigerator. The evaporated refrigerant returns to the compressor 60 via the suction pipe 66. In this case, a gas-liquid separator (accumulator) may be provided on the outlet side of the second cooler 22 and the third cooler 47, respectively, and the suction pipe 64,
66 may each be provided with a check valve. The reference numeral FM ₃ 61 in FIG. 5 indicates a fan motor for the condenser 7.

Next, to explain the brine circulation circuit, the brine 46 stored in the brine tank 8 is cooled to a required temperature by a third cooler 47 connected to the refrigeration circuit, and the brine 46 is cooled to a required temperature through a suction pipe led out from the tank 8. After being sucked out by the circulation pump 40 via the pump 39, it is supplied to the first cooler 17 via the discharge pipe 42 and the supply pipe 67. After cooling the first cooler 17 and exchanging heat with the air inside the warehouse, the brine is returned to the brine detection tank 51 from the return pipe 68 through the key-shaped discharge pipe 43.

As described above, some of the brine returned to the detection tank 51 flows down from the return hole 53, and the rest overflows from the upper edge 51c of the side wall of the detection tank 51 and is stored in the brine tank 8. Detection tank 51

The contact is ON.

Effect of the invention Next, the operating conditions of the horizontal refrigerator according to the invention will be explained.

Prior to operation of the apparatus, the front cover 5 of the cooling unit section 2 of the refrigerator is removed, the electrical equipment box 13 is pulled out, and the lid 33 of the brine tank 8 is removed to open the tank 8. Next, brine is injected into the brine tank 8, and the injection amount is the sum of the capacity of the brine 46 present in the circulation pipe system and the amount stored at the appropriate liquid level in the brine tank 8. . After the brine injection is completed, the lid 33 is reattached, the electrical equipment box 13 is inserted into a predetermined position, and the front cover 5 is attached to the cooling unit section 2.

When the power is turned on to operate the refrigerator, the power lamp _L1 lights up to indicate that the refrigerator is in operation. Since the internal temperature of the storage is kept at around room temperature, the contact point of the internal thermometer _Th3 equipped with the temperature sensing part 56 is "c-".
It closes between 'a'. Therefore, normally closed contact 5b-1 of relay X5 and normally closed contact 4b of relay
The relay X1 is energized via the relay
The CM and condenser fan motor FM ₃ start up and begin operating the refrigeration system. At the same time, the pump motor PM for brine circulation is activated at contact a of the cam timer TM.
The starting rotation is made via -c. In this cam timer TM, a built-in motor M starts rotating when the power is turned on, and the cooling time is integrated.

When the pump motor PM rotates, the brine 46 in the brine tank 8 is sucked through the suction pipe 39 and starts being supplied to the first cooler 17 via the discharge pipe 42 and the supply pipe 67. However, in the brine detection tank 51 disposed in the tank 8, the brine returned from the first cooler 17 is detected in the discharge pipe 4.
Since it does not flow down from 3, the float switch
The float 55a of the FSW 55 is located below, so its contacts a-b are open.

Also, since the relay X1 is energized, its normally open contact 1a-2 is closed, and the solenoid (not shown) of the solenoid valve _V2 is energized and opened via the normally closed contact 2b of the relay X2. The refrigerant from the refrigeration system is
It is circulated to the cooler 22. That is, the refrigerant is compressed by the compressor CM60, condensed and liquefied by the condenser 7, passes through the dryer 62 and the solenoid valve _V2 , is depressurized by the capillary reach tube 65, becomes a low-temperature liquefied refrigerant, and is sent to the second cooler. 22, where it exchanges heat with the air inside the refrigerator, evaporates, and returns to the compressor CM from the suction pipe 66 as a gas refrigerant, repeating the cycle. Further, the fan motor FM ₂ starts rotating via the normally closed contact 2b of the relay X2 and the normally closed contact 5b-2 of the relay 2 By exchanging heat with the cooler 22 and then discharging,
Cooling inside the refrigerator starts.

The first cooler 17 is fed by pressure from the pump motor PM.
After a while, the brine that has passed passes through the return pipe 68 and begins to flow down from the discharge pipe 43 into the brine detection tank 51. At this time, as described above, the amount of brine flowing out from the drain hole 53 formed in the bottom surface 51a of the brine detection tank 51 is set to be smaller than the amount of brine flowing into the tank 51 from the discharge pipe 43. There is. Therefore, part of the brine that has flowed down from the drain hole 53 to the brine tank 8, and most of it is stored in the brine detection tank 51, and its liquid level gradually rises. Due to this rise in the liquid level, the brine finally overflows from the upper edge 51c of the side wall of the detection tank 51 and begins to flow down into the brine tank 8 below. The float 55a of the float switch FSW floats up as the liquid level in the tank 51 rises, closing the contacts a and b.

In this way, contact a- of the float switch FSW
When b is closed, the relay X2 is energized via the normally closed contact 7b of the relay X7 and the a-c contacts of the cam timer TM, and in order to close the normally open contact 2a and open the normally closed contact 2b, the solenoid valve V ₂ The valve closes when the power is cut off, and the fan motor FM ₂ (second cooler 2
2) stops its rotation. At the same time, normally open contact 2
By closing a, normally closed contact 32b of relay X32
-1, solenoid valve _V1 opens, and the fan motor
FM ₁ (for the first cooler 17) also starts rotating.

When the previously open solenoid valve V ₂ closes and the previously closed solenoid valve V ₁ opens, the flow of liquefied refrigerant from the refrigeration system is switched to the third cooler 47 in the brine tank 8. Head towards. i.e. solenoid valve
The liquefied refrigerant that has passed through V ₁ is depressurized by the capillary reach tube 63 and flows into the third cooler 47.
Brine 4 in contact with this cooler 47 in an immersed state
6, the vaporized refrigerant returns to the compressor via the suction pipe 64, repeating the circulation cycle.

The brine 46 that has exchanged heat with the third cooler 47 through the circulation of the refrigerant is cooled and its temperature gradually decreases. This cooled brine 46 is supplied to the first cooler 17 by the pump motor PM, where it exchanges heat with the air inside the warehouse to cool the inside of the warehouse. The brine whose temperature has increased due to heat exchange returns to the brine tank 8 from the discharge pipe 43 via the return pipe 68,
After being cooled by heat exchange with the third cooler 47, a series of circulation cycles toward the first cooler 17 are repeated.

When the cycle of cooling the inside of the refrigerator with the cooled brine is repeated, the temperature inside the refrigerator gradually decreases. In particular, when the amount of brine circulation is increased and the surface area of the first cooler 17 is increased, the amount of heat exchanged with the air inside the refrigerator increases. Moreover, since the temperature difference between the internal temperature and the first cooler 17 is extremely small, the first
The amount of frost on the cooler 17 is reduced, and the interior of the refrigerator is less dehumidified, so high humidity is maintained.

When the internal temperature of the refrigerator falls to a predetermined value, the internal thermostat _Th3 detects this, and the contact ca switches to the contact c-b in FIG. 7. Furthermore, the internal thermostat
When the temperature set for Th ₃ is 0° C. or higher, there is no frost on the first cooler 17, so contacts a-b of the defrosting thermometer Th ₁ attached to this cooler 17 do not close. However, if the set temperature of the internal thermometer Th ₃ is below 0°C, frost will form in the first cooler 17.
The defrosting thermostat _Th1 closes its contacts a and b before the internal thermostat _Th3 is activated.

As mentioned above, the internal thermostat _Th3 operates and the contact c
When switching from -a to contact c-b, relay X1 is deenergized and rotation of compressor CM and fan motor FM ₃ is stopped. Also, contact c of internal thermostat Th ₃
Relay X4 is energized via time-limiting contacts c-d of timer T and timer T, and by closing its normally open contact 4a, relay X4 is self-held. At the same time, timer T is also energized and time measurement starts. This timer T opens contacts c-d when a predetermined time has elapsed, deenergizes relay X4, opens normally open contact 4a, and releases self-holding.

When the operation of the refrigeration device 6 is stopped in this way,
Although the third cooler 47 no longer cools the brine,
The amount of brine stored in the brine tank 8 is
The amount is several times larger than the amount present in the circulation pipes, and since the brine tank 8 blocks heat from entering from the outside with the heat insulating material 32, it has a high cold storage effect. Therefore, the stored brine 46 is circulated by the pump motor PM and continues to cool the first cooler 17.

However, the temperature inside the storage warehouse gradually rises due to various causes such as heat entering from the outside through the heat insulating material 16, heat entering due to opening and closing of the door 4, and heat radiation from stored items. The first cooler 17 is also heated by the internal air circulated by the fan motor FM ₁ , and therefore the brine circulating in the cooler 17 is also gradually warmed, and the brine returning to the brine tank 8 gradually warms the first cooler 17. The temperature of the stored brine also begins to rise gradually. And the temperature inside the refrigerator is thermo
When the upper limit set temperature of Th ₃ is reached, the contact point of the thermometer Th ₁ is switched from the "c-d" side to the "ca" side. This turns off timer T. In addition, relay X1 is energized via contact c-a of internal thermostat _Th3 , normally closed contact 5b-1 of relay X5, and normally closed contact 4b of X4, and closes its normally open contact 1a-1, causing the compressor to Restart operation of CM and fan motor FM ₃ . Therefore, the refrigerant is circulated to the third cooler 47, and cooling of the brine 46 in the tank 8 is resumed.

The brine cooled by the third cooler 47 is
It is supplied to the first cooler 17 to cool the air inside the warehouse,
When the lower limit set temperature is reached, the contact point of the internal thermostat _Th3 switches from the "ca" side to the "cb" side, and the operation of the refrigerator section 6 is stopped. By repeating this process, the temperature inside the refrigerator is maintained at a constant temperature.

Effects of the Invention As explained above, according to the horizontal refrigerator according to the present invention, the refrigeration device is disposed at the lower position of the cooling unit section, and the brine tank is disposed at the upper position, unlike the conventional refrigerator. Compared to the configuration in which the cooling unit part protrudes into the refrigerator, the internal volume of the refrigerator becomes larger, and space can be used more effectively. Furthermore, since there is no need to process the cooling unit section to protrude toward the inside of the refrigerator, manufacturing time and effort can be saved and costs can be reduced. Furthermore, since the cooler can be installed on a flat side surface inside the storage, assembly and maintenance and inspection operations are facilitated. Moreover, the electrical equipment box, which houses heat-sensitive semiconductors and other electrical parts, is generally isolated from heat-generating parts such as condensers, compressors, and fan motors through brine tanks.
It becomes possible to actively avoid the influence of heat radiation from the heat generating portion, and stable operation and longer life of electrical components can be achieved. In addition, the fixing member that supports the brine tank has through holes drilled at appropriate locations.
Moisture that condenses and drips into the discharge pipe or return pipe falls to the bottom surface below the cooling unit through the through holes, and this water is further evaporated to dryness by the heated air. Therefore, beneficial effects such as preventing the machine frame from corroding and the refrigerator installation surface from getting wet due to the moisture are achieved.
