A plurality of heat pump units 6 may be provided for the storage tank to control the individual operation. In this case, the heating capacity adjustment range is expanded, and in the unlikely event that a part of the heat pump unit 6 is broken. It may be possible to use a cleaning device.

  Next, the operation and action of the cleaning and drying operation will be described. A predetermined boiling state of the heat medium in the storage tank 9 is detected, the circulation pump 17 is driven, and the high temperature heat medium is supplied to the heat medium supply path 15. The cleaning liquids 19a to 19f in the cleaning tanks 18a to 18f are heated by the heat medium supplied so as to heat the cleaning liquid heat exchangers 21a to 21f from the heat medium supply path 15 by driving the pumps 22a to 22f. It will be. The heat medium constitutes a circulation path that flows into the heat medium return path 16 through the control valves 23a to 23f, sucked by the circulation pump 17, and returned to the lower portion of the storage tank 9. The control valves 23a to 23f control the circulation amount of the heat medium supplied to the cleaning liquid heat exchangers 21a to 21f and adjust the cleaning liquids 19a to 19f to a set temperature. The circulation rate of the heat medium supplied to the cleaning liquid heat exchangers 21a to 21f may be such that each of the pumps 22a to 22f has a variable rotation speed. Further, the temperature of each of the cleaning liquids 19a to 19f is detected, and the degree of opening of the control valves 23a to 23f or the number of rotations of the pumps 22a to 22f is controlled based on the detected value. Can be adjusted automatically.

The temperature tends to decrease, and the degree of cooling decreases as the object to be cleaned moves to the cleaning liquids 19b to 19f. As described above, the temperature of the cleaning liquids 19a to 19f is likely to change depending on the movement of the object to be cleaned, the processing amount, the heat capacity, etc., but the cleaning liquid heat exchangers 21a to 21f are provided corresponding to the cleaning liquids 19a to 19f.

  Further, when the object to be cleaned is not required to be dried or in a standby state, the pump 26 is stopped or the control valve 27 is closed to stop the supply of the heat medium to the hot air generating heat exchanger 25. Accordingly, it is possible to control the drying unit 24 in accordance with operating conditions such as cleaning and drying, thereby preventing wasteful heat dissipation. Thus, further power saving can be achieved by using a heat medium heated by a radiator of a heat pump cycle as a heat source in a series of steps in which the object to be cleaned is cleaned and dried.

The control valve 30 controls the circulation amount of the heat medium supplied to the heating heat exchanger 28 and adjusts the heating capacity. Further, the circulation amount of the heat medium supplied to the heating heat exchanger 28 may be such that the pump 29 can be rotated. Furthermore, by detecting the room temperature and controlling the opening degree of the control valve 30 or the rotation speed of the pump 29 based on the detected value, the temperature can be automatically adjusted to the set temperature.

  Further, when heating is unnecessary, the pump 29 is stopped driving or the control valve 30 is closed, the supply of the heat medium to the heating heat exchanger 28 is stopped, and control is performed according to the necessity of heating. Heat dissipation can be prevented.

  As described above, further power saving can be achieved by using the heat medium heated by the radiator of the heat pump cycle as the heat source in a series of steps for performing heating up to the factory in addition to cleaning the object to be cleaned.

It is for use. The heat medium flows through the control valve 33 to the heat medium return path 16 and is sucked by the circulation pump 17 to return to the lower portion of the storage tank 9. The adjusting valve 33 controls the circulation amount of the heat medium supplied to the feed water heat exchanger 31 and adjusts the heating capacity.

  In addition, the circulation amount of the heat medium supplied to the feed water heat exchanger 31 may be controlled by making the pump 32 variable. When feed water heating is not required, the pump 32 is stopped or the control valve 33 is closed, the supply of the heat medium to the feed water heat exchanger 31 is stopped, and control is performed as necessary to use wasteful heat dissipation. Can be prevented.

  As described above, further power saving can be achieved by using the heat medium heated by the radiator of the heat pump cycle, including heating in the factory where the cleaning device is located or supplying water such as hand-washing water for workers and drinking water. Can be planned.

  The heat medium supply pipe 36 branched from the heat medium supply path 15 supplies the heat medium to the cleaning tanks 18a to 18d when necessary by the opening / closing operation of the on-off valve 37. When the cleaning liquid in the cleaning tanks 18a to 18d is periodically discharged to clean the dirt in the cleaning tanks, the cleaning tanks can be cleaned more effectively by supplying the high-temperature heat medium. .

Further, the circulation amount of the heat medium supplied to the makeup water heat exchanger 39 may be such that the pump 43 can be rotated at a variable speed. Further, by detecting the temperature of the makeup water outlet pipe 40 and controlling the opening degree of the adjusting valve 44 or the rotation speed of the pump 43 based on the detected value, the makeup water can be automatically adjusted to the set temperature. Further, when supply of makeup water is not necessary, the pump 43 is stopped or the control valve 44 is closed to stop the supply of the heating medium, and the supply of the heating medium is controlled according to the necessity of supplying the makeup water. And wasteful heat dissipation can be prevented.

  As described above, in the process of cleaning the object to be cleaned, supply water is supplied to the cleaning tank, and the cleaning liquid is continuously or intermittently overflowed and discharged from the cleaning tank to maintain the cleaning performance. Since it preheats and supplies with a supplementary water heat exchanger, the temperature change of the washing | cleaning liquid in a washing tank can be decreased.

  Pure water as make-up water is supplied from the deionized water device 45 to the cleaning tank 18f through the pure water supply pipe 46, the make-up water heat exchanger 47, and the make-up water outlet pipe 48. At this time, the heat medium is brought into contact with the makeup water heat exchanger 47 from the heat medium supply path 15 and then circulated through the heat medium return pipe 50, the pump 51, and the adjustment valve 52 to the heat medium return path 16. Further, the circulation amount of the heat medium supplied to the makeup water heat exchanger 47 may be such that the pump 51 can be made variable in rotation speed. Further, by detecting the temperature of the makeup water outlet pipe 48 and controlling the opening degree of the adjustment valve 52 or the rotation speed of the pump 51 based on the detected value, the makeup water can be automatically adjusted to the set temperature. If supply of make-up water is unnecessary, stop driving the pump 51 or close the control valve 52 to stop the supply of the heat medium, and control the drying unit 24 according to the need for supply of make-up water, Wasteful heat dissipation can be prevented.

  As described above, supply water is supplied to the cleaning tank in the process of cleaning the object to be cleaned, and the cleaning liquid is continuously or intermittently overflowed and drained from the cleaning tank to maintain the cleaning performance. Since the pure water is preheated by the replenishing water heat exchanger and supplied, the temperature change of the cleaning liquid in the cleaning tank can be reduced.

A cleaning apparatus according to Embodiment 2 of the present invention will be described with reference to the block diagram of FIG. In FIG. 2, the same numbers as those in FIG. The difference from FIG. 1 is that the cleaning liquids 19a to 19f in the cleaning tanks 18a to 18f are circulated to exchange heat with the heat medium supplied from the storage tank 9.

  2, cleaning liquid heat exchangers 54a to 54f for exchanging heat with the heat medium in the heat medium pipe 57 corresponding to each of the cleaning tanks 18a to 18f, circulation pumps 55a to 55f for circulating the cleaning liquids 19a to 19f, and cleaning liquid circulation The paths 56a to 56f are provided, and the cleaning liquids 19a to 19f in the cleaning tanks 18a to 18f are circulated thereby to exchange heat with the heat medium supplied from the storage tank 9.

  A predetermined heating state of the heat medium in the storage tank 9 is detected, and the high-temperature heat medium supplied to the heat medium supply path 15 by driving the circulation pump 17 enters each heat medium pipe 57 and the control valves 23a to 23f. After that, a circulation path that flows into the heat medium return path 16 and is sucked by the circulation pump 17 and returns to the lower part of the storage tank 9 is configured. The control valves 23 a to 23 f adjust the circulation amount of the heat medium supplied to each heat medium pipe 57. As for the circulation amount of the cleaning liquids 19a to 19f supplied to the cleaning liquid heat exchangers 54a to 54f, each of the circulation pumps 55a to 55f may have a variable rotation speed. Furthermore, each of the cleaning liquids 19a to 19f can be automatically adjusted to the set temperature by detecting the temperature of each of the cleaning liquids 19a to 19f and controlling the number of rotations of the pumps 22a to 22f based on the detected value.

  In the cleaning apparatus of the second embodiment, the same effect as that of the cleaning apparatus of the first embodiment can be obtained, but the cleaning liquids 19a to 19f in the cleaning tanks 18a to 18f are further circulated by the circulation pumps 55a to 55f. Thus, by performing heat exchange with the heat medium supplied from the storage tank 9, a forced circulation flow is generated in the cleaning liquids 19a to 19f in the cleaning tanks 18a to 18f, and the cleaning liquids 19a to 19f are more uniformly heated. Can be adjusted to.

(Embodiment 3)
A cleaning apparatus according to Embodiment 3 of the present invention will be described with reference to the block diagram of FIG. In FIG. 3, the same reference numerals as those in FIGS. In particular, what is fundamentally different from FIG. 2 is that the order in which the heat medium supplied from the inside of the storage tank 9 flows and the flow path can be selected.

  In FIG. 3, the heat medium that has entered the heating heat exchanger 28 from the heat medium supply path 15 is configured to flow again to the heat medium supply path 15 via the on-off valve 59 and the heat medium return pipe 60. The heat medium that has entered the hot air generating heat exchanger 25 from the path 15 is configured to flow again to the heat medium supply path 15 via the on-off valve 61 and the heat medium return pipe 62. A bypass pipe 63 and an opening / closing valve 64 communicating with the heat medium supply path 15 are provided, and a flow path for directly flowing the heat medium to the heat medium pipe 57 when the heat medium is not flowed to the hot air generating heat exchanger 25 is configured. Yes. Further, the cleaning liquid heat exchangers 21 a to 21 f are heated, and the heat medium that has passed through each heat medium pipe 57 is returned to the lower portion of the storage tank 9 via the on-off valve 65, the heat medium branch return path 66, and the heat medium branch return path 67. It constitutes a circulation path. The heat medium that has passed through each heat medium pipe 57 passes through the on-off valve 68, the heat medium branch return path 69, the heat medium branch return path 70, the heat medium branch return path 71, and the heat medium branch return path 67. It constitutes a circulation path to return to.

  Next, the operation in this embodiment will be described. When the on-off valve 64, the on-off valve 68, and the on-off valve 37 are closed and the on-off valve 59 and the on-off valve 61 are opened, the heat medium flows into the heating heat exchanger 28 and the hot air generating heat exchanger 25, and the heat medium return. After passing through the pipe 60 and the heat medium return pipe 62, each heat medium pipe 57 flows from the heat medium supply path 15 to sequentially heat the cleaning liquid heat exchangers 54a to 54f. After heating the cleaning liquid heat exchanger 54f, the heat medium returns to the lower part of the storage tank 9 through the on-off valve 65, the heat medium branch return path 66, and the heat medium branch return path 67. In this operation, in addition to heating in the factory, the cleaning liquids 19a to 19f in the cleaning tanks 18a to 18f are heated and temperature-controlled, and the product to be cleaned in the drying unit 24 is dried.

  When there is no need for heating in the factory, the on-off valve 59 is closed and the on-off valve 61 is opened. As a result, the heat medium flows from the upper part of the storage tank 9 to the hot air generating heat exchanger 25 without passing through the heating heat exchanger 28, passes through the heat medium return pipe 62, and then passes through the heat medium supply path 15 to each heat medium pipe 57. The cleaning liquid heat exchangers 54a to 54f are sequentially heated. After heating the cleaning liquid heat exchanger 54f, the heat medium returns to the lower part of the storage tank 9 through the on-off valve 65, the heat medium branch return path 66, and the heat medium branch return path 67.

  Further, when the temperature of the cleaning liquids 19a to 19f is being raised to a certain temperature and the product to be cleaned in the drying unit 24 does not need to be dried, the on-off valve 59 and the on-off valve 61 are closed. As a result, the heat medium flows from the upper part of the storage tank 9 through the bypass pipe 63 and the on-off valve 64 communicating with the heat medium supply path 15 without passing through the hot air generating heat exchanger 25 and the heating heat exchanger 28, and the heat medium pipe 57. The cleaning liquids 19a to 19f can be concentrated and heated. Further, by opening the on-off valve 64 and adjusting the opening degree of the on-off valve 61, it is possible to preheat the hot air generating heat exchanger 25 with a small amount of heat medium.

  A state in which the on-off valve 65 and the on-off valve 37 are closed and the on-off valve 68 is opened will be described. The heat medium flowing through the heat medium pipe 57 from the heat medium supply path 15 sequentially heats the cleaning liquid heat exchangers 54a to 54f, and after heating the cleaning liquid heat exchanger 54f, the heat medium is the on-off valve 68, the heat medium. Flowing into the branch return path 69, heating the makeup water heat exchanger 47 for pure water and the makeup water heat exchanger 39 for tap water, passing through the heating medium branch return path 70, and supplying water for tap water used for hand-washing etc. The exchanger 31 is heated, and further returns to the lower part of the storage tank 9 through the heat medium branch return path 71 and the heat medium branch return path 67. Further, when the tap water is heated by the feed water heat exchanger 31 for hand washing and drinking, it is performed by operating an on-off valve (not shown) provided in the tap water supply pipe 34.

  As described above, in the present embodiment, it is possible to select an order and a flow path for flowing the heat medium from the storage tank 9, and an optimum operation can be performed for various situations.

  As in the first and second embodiments, the temperature of the cleaning liquids 19a and 19b using the tap water containing the cleaning agent in the cleaning tanks 18a and 18b is set to 60 ° C., and the tap water from the cleaning tanks 18c and 18d is changed to the tap water. The temperature of the cleaning liquids 19c and 19d used is set to 40 degrees C, the temperature of the cleaning liquids 19e and 19f using pure water in the cleaning tanks 18e and 18f is set to 40 degrees C, and the objects to be cleaned are in the order of the cleaning liquids 19a to 19f. Although the object to be cleaned is immersed in the cleaning liquid 19a first, the cleaning liquid 19a is cooled by the object to be cleaned and the temperature is easily lowered. The degree of cooling decreases as it moves from 19b to 19f. Further, heat dissipation from the cleaning liquids 19a and 19b and the cleaning tanks 18a and 18b set at higher temperatures also increases.

  Accordingly, among the plurality of cleaning liquids 19a to 19f set to different temperatures, the cleaning liquid heat exchanger 19c for the cleaning liquid set to a lower temperature from the side of the cleaning liquid heat exchangers 54a and 54b of the cleaning liquids 19a and 19b set to a higher temperature. By sequentially supplying a high-temperature heat medium in the storage tank 9 and returning it to the storage tank so as to heat the ˜19f side, each cleaning liquid is accurately adjusted to the set temperature in response to a temperature change of the cleaning liquid. Can be adjusted and maintained well. Furthermore, the cleaning liquids 19a to 19f can be effectively heated and the heat of the heat medium can be effectively utilized.

  Further, the hot air generating heat exchanger 25 or the heating heat exchanger 28 requires a heat medium having a temperature higher than that of the cleaning liquids 19a to 19f. In particular, the hot air generating heat exchanger 25 requires a high-temperature heat medium in order to generate hot air and quickly dry the object to be cleaned. Therefore, after supplying the heat medium in the storage tank 9 so as to heat the hot air generating heat exchanger 25 or the heating heat exchanger 28 that performs heat exchange between the air and the heat medium, a plurality of cleaning liquid heat exchangers 19a are provided. By sequentially supplying the ˜19f side so as to be heated and returning it to the storage tank, the object to be cleaned can be quickly dried and the heat of the heat medium can be effectively utilized.

  Further, if necessary, a replenishing water heat exchanger 39 for heating tap water which is replenishing water to be supplied to the washing tanks 18b and 18d via the replenishing water outlet pipe 40 and a washing tank as necessary via the replenishing water outlet pipe 48. The replenishing water heat exchanger 47 that heats pure water that is replenishing water supplied to 18f requires less heat load than the cleaning liquids 19a to 19f. Alternatively, the feed water heat exchanger 31 for heating the tap water from the tap water supply pipe 34 is used for hand washing and drinking.

  Therefore, after supplying the heat medium in the storage tank 9 so as to heat the plurality of cleaning liquid heat exchangers 19a to 19f, the heat medium is sequentially supplied so as to heat the replenishing water heat exchanger or the feed water heating heat exchanger. By returning to the storage tank, the cleaning liquids 19a to 19f can be accurately adjusted and maintained at the set temperature, and the heat of the heat medium can be effectively utilized.

In particular, the difference from FIGS. 1 to 3 is on the inlet side of the heat medium heat exchanger 10 so that the heat medium flowing into the heat medium heat exchanger 10 of the heat medium storage circuit 12 has a predetermined temperature or less. A heat dissipation means for the heat medium is provided.

  As described above, the high-temperature and high-pressure refrigerant that is higher than the critical pressure discharged from the compressor 1 flows into the radiator 2, where water and the heat medium that are the heat medium sent from the lower part of the storage tank 9 by the circulation pump 11. Heat is exchanged through the heat exchanger 10. The high-temperature refrigerant flowing into the radiator 2 and the heat medium (water) flowing out from the heat medium heat exchanger 10 are exchanged with each other to exchange heat, and heated to a predetermined temperature with the high-temperature refrigerant flowing into the radiator 2. The heat medium heat exchanger 10 is returned to the upper part of the storage tank 9. On the other hand, the high-temperature refrigerant that has flowed into the radiator 2 decreases its temperature by the heat radiation action, flows out of the radiator 2, and flows into the decompression device 3. Then, the decompressed refrigerant is passed through the air heat exchanger 4. The refrigerant that has flowed into the air heat exchanger 4 absorbs atmospheric heat and is sucked into the compressor 1. The operation of the heat pump unit 6 is performed, and a high-temperature heat medium of, for example, 90 degrees C is stored in the storage tank 9. The heat medium in the storage tank 9 flows into the heat medium supply path 15, heats the hot air generating heat exchanger 25, the cleaning liquid heat exchangers 54 a to 54 f, etc., and then stores through the heat medium return path 16 and the circulation pump 17. Return to the bottom of the tank 9.

  An on-off valve 72 and a temperature detector 79 are provided on the heat medium inflow side of the heat medium heat exchanger 10 located in the storage circulation path 12, and the heat radiation forward pipe branched from the storage circulation path 12 below the storage tank 9. 74, the on-off valve 73, the heat radiation heat exchanger 75, and the heat radiation return pipe 76 are communicated, and the heat radiation return pipe 76 is communicated with the storage circuit 12 between the on-off valve 72 and the circulation pump 11. The heat radiation heat exchanger 75 is located in the tank 77, heats the tap water supplied from the tap water supply pipe 80, and uses the hot water from the discharge pipe 78. The on-off valve 72, the on-off valve 73, and the temperature detector 79 constitute switching means for changing the flow of the heat medium.

  In such a configuration, when the temperature detector 79 detects, for example, 35 degrees C or less, the on-off valve 72 is opened, the on-off valve 73 is closed, and the heat medium is circulated in the storage circuit 12 to perform normal operation. . When the temperature detector 79 detects, for example, 35 ° C. or more, the on-off valve 73 is opened, the on-off valve 72 is switched to close, the heat medium is passed through the heat dissipation heat exchanger 75, and the heat in the tank 77 is dissipated. The heat medium is returned from the heat return pipe 76 to the storage circuit 12 and circulated, and the heat medium flowing into the heat medium heat exchanger 10 is controlled so as not to exceed a predetermined temperature of, for example, 35 degrees C.

  In particular, the amount of heat exchange from the radiator 2 to the heat medium heat exchanger 10 is reduced, the pressure of the refrigerant circuit 5 is increased, and the compressor 1 is frequently operated and stopped by the detection of the pressure detector 7. In this case, since the compressor 1 cannot start re-operation for several minutes after the stop (for example, 3 to 5 minutes), it is not possible to supply a heat medium of, for example, 90 degrees C to the upper part of the storage tank 9 during this period. 9 lowers the temperature of the heating medium in the upper part in particular, and causes instability. For this reason, a stable heat medium at a high temperature cannot be supplied to the heat medium supply path 15. Further, frequent operation and stop operation are not preferable from the viewpoint of the durability of the compressor 1.

  On the other hand, in the present embodiment, the compressor 1 varies the rotational speed by controlling the heat medium flowing into the heat medium heat exchanger 10 so as not to exceed a predetermined temperature of, for example, 35 degrees C. Even if it is not an inverter control system, the increase in the pressure of the refrigerant circuit 5 due to a decrease in the heat exchange amount from the radiator 2 to the heat medium heat exchanger 10 is suppressed, and the compressor 1 is frequently detected by the detection of the pressure detector 7. Operation and stop can be suppressed. As a result, it is possible to supply a stable heat medium at a high temperature to the heat medium supply path 15, improve the durability of the compressor 1, and further effectively utilize the retained heat of the heat medium in the heat radiating heat exchanger 7. it can.

  In the present embodiment, the means for radiating heat by the heat radiating heat exchanger 7 is shown, but another means such as a cooling tower may be used.

(Embodiment 5)
A cleaning apparatus according to a fifth embodiment of the present invention will be described with reference to the block diagram of FIG. 5, the same reference numerals as those in FIGS. 1 to 3 denote the same parts, and a description thereof is omitted.

It is something to be made.

  A temperature detector 81 is provided on the outlet side of the air heat exchanger 4, and a high-temperature heat exchanger 82 is provided between the outlet side of the air heat exchanger 4 and the inlet side of the compressor 1 and sequentially connected in an annular shape. The heat pump cycle having the refrigerant circuit 5 is configured. The high temperature heat exchanger 82 and the heat medium return heat exchanger 83 are provided in a heat exchange relationship, and the heat medium from the heat medium return path 16 is passed through the heat medium return heat exchanger 83 to increase the temperature increase heat exchanger. The refrigerant is heated at 82. On-off valves 85 and 86 are provided in communication with the heat medium return path 16, and the on-off valve 86 is located in the bypass pipe 87. The heat medium return path 16 is provided with a temperature detector 84 for detecting the temperature of the heat medium.

  In such a configuration, when the heat medium temperature from the heat medium return path 16 is higher than the refrigerant temperature on the outlet side of the air heat exchanger 4 and the refrigerant at the outlet of the air heat exchanger 4 is below a predetermined temperature, the on-off valve 86 Is closed, the on-off valve 85 is opened, the heat medium from the heat medium return path 16 is caused to flow to the heat medium return heat exchanger 83, and the high temperature heat exchanger 82 heats the refrigerant. Then, the refrigerant temperature at the outlet of the high-temperature heat exchanger 82 is made higher than the refrigerant temperature at the outlet of the air heat exchanger 4 to make the refrigerant temperature sucked into the compressor 1 into a high-temperature superheated gas, and the refrigerant temperature at the outlet of the compressor 1 is raised. This makes it possible to increase the efficiency of the heat pump cycle by utilizing the retained heat of the heat medium from the heat medium return path 16.

  The present invention can also be applied to a cleaning apparatus for various articles that require cleaning.
