Summary of the Invention
Problems to be Solved by the Invention
[0004] By the way, in an adsorption heat pump, it is preferable to improve the heat exchange efficiency.
[0005] An object of the present invention is to provide an adsorption heat pump with improved heat exchange efficiency.
Means for Solving the Problems
[0006] The adsorption heat pump according to claim 1 includes an evaporator, a first adsorber including a first adsorbent that adsorbs the first adsorbate evaporated by the evaporator, a condenser that condenses the first adsorbate desorbed from the first adsorber, and a second adsorber provided in the condenser and including a second adsorbent that adsorbs a second adsorbate different from the first adsorbate.
[0007] In the adsorption heat pump according to claim 1, by providing a second adsorber provided in the condenser and including a second adsorbent that adsorbs a second adsorbate different from the first adsorbate, in the second adsorber, the second adsorbent adsorbs the second adsorbate. Therefore, a negative pressure is generated that pulls the first adsorbate and the second adsorbate from the first adsorber to the condenser. As a result, the movement of the first adsorbate and the second adsorbate is promoted, and the heat exchange efficiency can be improved without applying additional energy such as in an electric heat pump.
[0008] The adsorption heat pump according to claim 2 is the adsorption heat pump according to claim 1, wherein the second adsorbent does not adsorb the first adsorbate.
[0009] In the adsorption heat pump according to claim 2, since the second adsorbent does not adsorb the first adsorbate, the first adsorbate that has been desorbed in the first adsorber and has heat is not adsorbed by the second adsorbent. Therefore, the temperature rise of the second adsorber is suppressed, and the heat exchange efficiency can be improved.
[0010] The adsorption heat pump according to claim 3 is the adsorption heat pump according to claim 1 or claim 2, further comprising a diaphragm that partitions the condenser and the second adsorber, allows the second adsorbate to pass through, and does not allow the first adsorbate to pass through.
[0011] In the adsorption heat pump according to claim 3, by providing a diaphragm that partitions the condenser and the second adsorber, allows the second adsorbate to pass through, and does not allow the first adsorbate to pass through, the approach of the first adsorbate to the second adsorber is suppressed. Therefore, a situation where the first adsorbate that has been desorbed in the first adsorber and has heat contacts the second adsorber and the energy that should be extracted as condensation heat is lost is suppressed. As a result, the heat exchange efficiency can be improved.
[0012] The adsorption heat pump according to claim 4 is the adsorption heat pump according to any one of claims 1 to 3, wherein the first adsorbent does not adsorb the second adsorbate.
[0013] In the adsorption heat pump according to claim 4, since the first adsorbent does not adsorb the second adsorbate, the second adsorbent is not adsorbed in the first adsorber. Therefore, the second adsorbent acts as a heat medium that assists heat exchange between the first adsorber and the first adsorbent, instead of the first adsorbate that is adsorbed by the first adsorbent and decreases. As a result, the temperature rise of the first adsorber is suppressed, and the heat exchange efficiency can be improved.
Advantages of the Invention
[0014] As described above, according to the adsorption heat pump according to the present invention, the heat exchange efficiency can be improved.

Modes for Carrying Out the Invention
[0016] Hereinafter, the adsorption heat pump according to the embodiment will be described with reference to the drawings. The adsorption heat pump according to the embodiment generates cooling or heating by utilizing the latent heat generated when the adsorbate is adsorbed by the adsorbent and the latent heat generated when the adsorbate is desorbed from the adsorbent.
[0017] [Configuration of Adsorption Heat Pump 5] As shown in FIG. 1, the adsorption heat pump 5 includes an evaporator 30, a condenser 60, a right adsorber (an example of the first adsorber 10) 40, a left adsorber (an example of the first adsorber 10) 50, a second adsorber 70, a first adsorbent 81, and a second adsorbent 82. Further, the adsorption heat pump 5 includes a first duct 11 connecting the evaporator 30 and the right adsorber 40, a second duct 12 connecting the right adsorber 40 and the condenser 60, a third duct 13 connecting the condenser 60 and the left adsorber 50, a fourth duct 14 connecting the left adsorber 50 and the evaporator 30, and a fifth duct 15 connecting the condenser 60 and the evaporator 30.
[0018] Further, the adsorption heat pump 5 includes a first valve 21 provided in the first duct 11 for opening and closing the flow path of the first duct 11, a second valve 22 provided in the second duct 12 for opening and closing the flow path of the second duct 12, a third valve 23 provided in the third duct 13 for opening and closing the flow path of the third duct 13, a fourth valve 24 provided in the fourth duct 14 for opening and closing the flow path of the fourth duct 14, and a fifth valve 25 provided in the fifth duct 15 for opening and closing the flow path of the fifth duct 15.
[0019] (Evaporator 30) As shown in FIG. 1, the evaporator 30 is a heat exchanger for extracting cooling heat, and evaporates a liquid first adsorbent (for example, water) 81 to generate a gaseous first adsorbent 81.
[0020] The liquid first adsorbent 81 is stored in an evaporation chamber 30A inside the evaporator 30. A heat exchange section 31 is arranged in the evaporation chamber 30A. An evaporator pipe 32 is arranged in the heat exchange section 31 together with a plurality of fins (not shown). A heat medium (for example, water at 35°C) that exchanges heat in the evaporator 30 flows through the evaporator pipe 32. The evaporator pipe 32 is arranged in a meandering manner so as to effect sufficient heat exchange.
[0021] The evaporator pipe 32 conveys the cold generated when the liquid first adsorbent 81 evaporates by means of a heat medium to the outside. In other words, the liquid first adsorbent 81 evaporates, and the cold generated at that time is conveyed to the outside by the evaporator pipe 32 and used for cooling or the like.
[0022] (Right adsorber 40) As shown in FIG. 1, the right adsorber 40 adsorbs and desorbs the first adsorbent 81.
[0023] In the right adsorption chamber 40A of the right adsorber 40, a heat exchange part 41 and a first adsorbent 43 are provided.
[0024] In the heat exchange part 41, a pipe 42 for the right adsorber is arranged together with a plurality of fins (not shown). A heat medium (for example, water at 15°C or water at 60°C) that undergoes heat exchange in the right adsorber 40 flows through the pipe 42 for the right adsorber. By controlling the temperature of the heat medium, adsorption of the first adsorbent 81 or desorption of the first adsorbent 81 is performed in the right adsorber 40. The pipe 42 for the right adsorber is arranged in a meandering manner so that sufficient heat exchange is achieved.
[0025] The first adsorbent 43 is supported on the heat exchange part 41 and adsorbs and desorbs the first adsorbent 81. The first adsorbent 43 adsorbs the first adsorbent 81 evaporated in the evaporator 30. The first adsorbent 43 is made of a material capable of adsorbing and desorbing the first adsorbent 81, and can be, for example, silica gel or zeolite. From the viewpoint of improving the density of adsorption sites, the first adsorbent 43 is preferably a metal organic framework (MOF: Metal Organic Frameworks). The first adsorbent 43 is made of a material that does not adsorb the second adsorbent 82.
[0026] (Left adsorber 50) As shown in FIG. 1, the left adsorber 50 has the same configuration as the right adsorber 40 and adsorbs and desorbs the first adsorbent 81.
[0027] In the left adsorption chamber 50A of the left adsorber 50, a heat exchange section 51 and a first adsorbent 43 are provided.
[0028] In the heat exchange section 51, a pipe 52 for the left adsorber is arranged together with a plurality of fins (not shown). A heat medium (for example, water at 15°C or water at 60°C) that undergoes heat exchange in the left adsorber 50 flows through the pipe 52 for the left adsorber. By controlling the temperature of the heat medium, adsorption of the first adsorbate 81 or desorption of the first adsorbate 81 is performed in the left adsorber 50. The pipe 52 for the left adsorber is arranged in a meandering shape so that sufficient heat exchange is performed.
[0029] (Condenser 60) As shown in FIG. 1, the condenser 60 is a heat exchanger for extracting heat, cools and condenses the gaseous first adsorbate 81 desorbed from the right adsorber 40 or the left adsorber 50, and generates the liquid first adsorbate 81.
[0030] In the condensation chamber 60A of the condenser 60, a heat exchange section 61 is arranged. In the heat exchange section 61, a pipe 62 for the condenser is arranged together with a plurality of fins (not shown). A heat medium (for example, water at 35°C) that undergoes heat exchange in the condenser 60 flows through the pipe 62 for the condenser. The pipe 62 for the condenser is arranged in a meandering shape so that sufficient heat exchange is performed.
[0031] The pipe 62 for the condenser conveys to the outside the heat generated when the gaseous first adsorbate 81 desorbed from the right adsorber 40 or the left adsorber 50 condenses by the heat medium. In other words, the gaseous first adsorbate 81 desorbed from the right adsorber 40 or the left adsorber 50 is condensed, and the heat generated at that time is conveyed to the outside by the pipe 62 for the condenser and is used for heating and the like.
[0032] (First adsorbate 81 · Second adsorbate 82) The first adsorbent 81 is an adsorbent different from the second adsorbent 82, and can be, for example, water vapor. The second adsorbent 82 is a gas that becomes a gas in the operating temperature range, and can be, for example, carbon dioxide, ammonia, or the like. The second adsorbent 82 preferably does not condense in the condenser 60. The first adsorbent 81 is enclosed in the circulation path of the evaporator 30, the right adsorber 40, the left adsorber 50, and the condenser 60. The second adsorbent 82 is enclosed in the circulation path of the evaporator 30, the right adsorber 40, the left adsorber 50, the condenser 60, and the second adsorber 70.
[0033] (Second adsorber 70) The second adsorber 70 adsorbs and desorbs the second adsorbent 82.
[0034] In the second adsorption chamber 70A of the second adsorber 70, a heat exchange section 71 and a second adsorbent 73 are provided.
[0035] In the heat exchange section 71, a pipe 72 for the second adsorber is arranged together with a plurality of fins (not shown). A heat medium (for example, water at 15°C or water at 60°C) that undergoes heat exchange in the second adsorber 70 flows through the pipe 72 for the second adsorber. By controlling the temperature of the heat medium, adsorption of the second adsorbent 82 or desorption of the second adsorbent 82 is performed in the second adsorber 70. The pipe 72 for the second adsorber is arranged in a meandering manner so that sufficient heat exchange occurs.
[0036] The second adsorbent 73 is supported on the heat exchange section 71 and adsorbs and desorbs the second adsorbent 82. The second adsorbent 73 adsorbs a second adsorbent 82 different from the first adsorbent 81. The second adsorbent 73 is a material capable of adsorbing and desorbing the second adsorbent 82, and can be, for example, silica gel, zeolite, or the like. From the viewpoint of improving the density of adsorption sites, the second adsorbent 73 is preferably a metal organic framework (MOF). The second adsorbent 73 is a material that does not adsorb the first adsorbent 81.
[0037] The second adsorber 70 is provided in the condenser 60. The second adsorption chamber 70A of the second adsorber 70 and the condensation chamber 60A of the condenser 60 are partitioned by a diaphragm 65. In other words, the second adsorber 70 and the condenser 60 are provided in one room, and their installation spaces are separated by the diaphragm 65. The diaphragm 65 is a membrane that allows the second adsorbate 82 to pass through and does not allow the first adsorbate 81 to pass through, and can be, for example, a hydrophobic zeolite membrane, a polymer membrane containing a perfluoro group, or the like.
[0038] [Operation of the adsorption heat pump 5] In the adsorption heat pump 5, cold heat or warm heat is generated through an adsorption process, a preheating process, a desorption process, and a precooling process.
[0039] (Adsorption process of the right adsorber 40) As shown in FIG. 2, in the adsorption process of the right adsorber 40, the first valve 21 is opened, and the second valve 22 and the fifth valve 25 are closed. Then, a heat medium at a temperature (for example, 15°C) at which the first adsorbate 81 is adsorbed by the first adsorbent 43 flows through the pipe 42 for the right adsorber, and the first adsorbate 81 is adsorbed by the first adsorbent 43 in the right adsorber 40.
[0040] Here, in the right adsorber 40, when the gaseous first adsorbate 81 is adsorbed by the first adsorbent 43, a negative pressure acts on the right adsorption chamber 40A. Also, in the evaporator 30, when the liquid first adsorbate 81 evaporates, a positive pressure acts on the evaporation chamber 30A. Then, due to the action of the negative pressure in the right adsorption chamber 40A and the positive pressure in the evaporation chamber 30A, the gaseous first adsorbate 81 flows from the evaporation chamber 30A into the right adsorption chamber 40A through the first duct 11. At this time, riding on the flow of the first adsorbate 81, the second adsorbate 82 in the evaporation chamber 30A also flows into the right adsorption chamber 40A.
[0041] The cold heat generated when the liquid first adsorbate 81 evaporates is conveyed to the outside by the evaporator pipe 32 and used for cooling or the like.
[0042] (Preheating process of the right adsorber 40) As shown in FIG. 3, during the preheating process of the right adsorber 40, the fifth valve 25 opens, and the first valve 21 and the second valve 22 are closed. Then, a heat medium at a temperature (for example, 60° C.) at which desorption of the first adsorbate 81 by the first adsorbent 43 occurs is passed through the pipe 42 for the right adsorber, and the first adsorbate 81 is desorbed from the first adsorbent 43 of the right adsorber 40.
[0043] (Desorption process of the right adsorber 40) As shown in FIG. 4, during the desorption process of the right adsorber 40, the second valve 22 opens, and the first valve 21 and the fifth valve 25 are closed. Then, a heat medium at a temperature (for example, 60° C.) at which desorption of the first adsorbate 81 by the first adsorbent 43 occurs is passed through the pipe 42 for the right adsorber, and the first adsorbate 81 is desorbed from the first adsorbent 43 of the right adsorber 40. Also, a heat medium at a temperature (for example, 35° C.) at which condensation of the first adsorbate 81 by the condenser 61 occurs is passed through the pipe 62 for the condenser, and the first adsorbate 81 is condensed. Further, a heat medium at a temperature (for example, 15° C.) at which adsorption of the second adsorbate 82 by the second adsorbent 73 occurs is passed through the pipe 72 for the second adsorber, and the second adsorbate 82 is adsorbed by the second adsorbent 73 of the second adsorber 70.
[0044] Here, in the right adsorber 40, when the gaseous first adsorbate 81 is desorbed from the first adsorbent 43, a positive pressure acts on the right adsorption chamber 40A. Also, in the condenser 60, when the first adsorbate 81 is condensed, a negative pressure acts on the condensation chamber 60A. Further, in the second adsorption chamber 70A, when the second adsorbate 82 is adsorbed by the second adsorbent 73, a negative pressure acts on the second adsorption chamber 70A and thus on the condensation chamber 60A.
[0045] Then, due to the action of the positive pressure in the right adsorption chamber 40A and the negative pressure in the condensation chamber 60A, the gaseous first adsorbate 81 flows from the right adsorption chamber 40A into the condensation chamber 60A through the second duct 12. At this time, riding on the flow of the first adsorbate 81, the second adsorbate 82 in the right adsorption chamber 40A also flows into the condensation chamber 60A. Further, due to the action of the negative pressure in the second adsorption chamber 70A, the second adsorbate 82 that has flowed into the condensation chamber 60A passes through the diaphragm 65 and enters the second adsorption chamber 70A.
[0046] When the first adsorbate 81 of the gas condenses, the heat generated is conveyed to the outside by the condenser piping 62 and used for heating or the like.
[0047] (Pre-cooling process of the right adsorber 40) As shown in FIG. 5, in the pre-cooling process of the right adsorber 40, the fifth valve 25 opens, and the first valve 21 and the second valve 22 are closed. Then, a heat medium at a temperature (for example, 15° C.) at which the first adsorbate 81 is adsorbed by the first adsorbent 43 flows through the right adsorber piping 42, and the first adsorbate 81 is adsorbed by the first adsorbent 43 of the right adsorber 40.
[0048] Also, in the second adsorber 70, a heat medium at a temperature (for example, 60° C.) at which the second adsorbate 82 is desorbed by the second adsorbent 73 flows through the second adsorber piping 72, and the second adsorbate 82 is desorbed from the second adsorbent 73 of the second adsorber 70.
[0049] Here, in the second adsorber 70, when the second adsorbate 82 of the gas is desorbed from the second adsorbent 73, a positive pressure acts on the second adsorption chamber 70A and thus the condensation chamber 60A. Then, due to the action of the positive pressure in the condensation chamber 60A, the liquid first adsorbate 81 generated when the first adsorbate 81 of the gas condenses in the condenser 60 and the gas second adsorbate 82 flow into the evaporator 30 through the fifth duct 15.
[0050] (Adsorption process of the left adsorber 50) As shown in FIG. 4, the adsorption process of the left adsorber 50 is carried out at the same timing as the desorption process of the right adsorber 40. The fourth valve 24 opens, and the third valve 23 and the fifth valve 25 are closed. Then, a heat medium at a temperature (for example, 15° C.) at which the first adsorbate 81 is adsorbed by the first adsorbent 43 flows through the left adsorber piping 52, and the first adsorbate 81 is adsorbed by the first adsorbent 43 of the left adsorber 50.
[0051] Here, in the left adsorber 50, when the first adsorbate 81 of the gas is adsorbed by the first adsorbent 43, a negative pressure acts on the left adsorption chamber 50A. Also, in the evaporator 30, when the first adsorbate 81 in the liquid state evaporates, a positive pressure acts on the evaporation chamber 30A. Then, due to the action of the negative pressure in the left adsorption chamber 50A and the positive pressure in the evaporation chamber 30A, the first adsorbate 81 of the gas flows from the evaporator 30 to the left adsorber 50 through the fourth duct 14. At this time, along with the flow of the first adsorbate 81, the second adsorbate 82 in the evaporation chamber 30A also flows into the left adsorber 50.
[0052] The cold heat generated when the first adsorbate 81 in the liquid state evaporates is conveyed to the outside by the evaporator pipe 32 and used for cooling or the like.
[0053] (Preheating process of the left adsorber 50) As shown in FIG. 5, the preheating process of the left adsorber 50 is carried out at the same timing as the precooling process of the right adsorber 40. The fifth valve 25 is opened, and the third valve 23 and the fourth valve 24 are closed. Then, a heat medium at a temperature (for example, 60°C) at which the first adsorbate 81 is desorbed from the first adsorbent 43 flows through the left adsorber pipe 52, and the first adsorbate 81 is desorbed from the first adsorbent 43 of the left adsorber 50.
[0054] (Desorption process of the left adsorber 50) As shown in FIG. 2, the desorption process of the left adsorber 50 is carried out at the same timing as the adsorption process of the right adsorber 40. The third valve 23 is opened, and the fourth valve 24 and the fifth valve 25 are closed. Then, a heat medium at a temperature (for example, 60°C) at which the first adsorbate 81 is desorbed from the first adsorbent 43 flows through the left adsorber pipe 52, and the first adsorbate 81 is desorbed from the first adsorbent 43 of the left adsorber 50. Also, a heat medium at a temperature (for example, 35°C) at which the first adsorbate 81 is condensed by the condenser 61 flows through the condenser pipe 62, and the first adsorbate 81 is condensed. Further, a heat medium at a temperature (for example, 15°C) at which the second adsorbate 82 is adsorbed by the second adsorbent 73 flows through the second adsorber pipe 72, and the second adsorbate 82 is adsorbed by the second adsorbent 73 of the second adsorber 70.
[0055] Here, in the left adsorber 50, when the first adsorbate 81 of the gas is desorbed from the first adsorbent 43, a positive pressure acts on the left adsorption chamber 50A. Further, in the condenser 60, when the first adsorbate 81 condenses, a negative pressure acts on the condensation chamber 60A. Furthermore, in the second adsorption chamber 70A, when the second adsorbate 82 is adsorbed by the second adsorbent 73, a negative pressure acts on the second adsorption chamber 70A and thus on the condensation chamber 60A.
[0056] Then, due to the action of the positive pressure in the left adsorption chamber 50A and the negative pressure in the condensation chamber 60A, the first adsorbate 81 of the gas flows from the left adsorption chamber 50A into the condensation chamber 60A through the third duct 13. At this time, riding on the flow of the first adsorbate 81, the second adsorbate 82 in the left adsorption chamber 50A also flows into the condensation chamber 60A. Furthermore, due to the action of the negative pressure in the second adsorption chamber 70A, the second adsorbate 82 that has flowed into the condensation chamber 60A passes through the diaphragm 65 and enters the second adsorption chamber 70A.
[0057] The heat generated when the first adsorbate 81 of the gas condenses is conveyed to the outside by the condenser piping 62 and used for heating or the like.
[0058] (Pre-cooling process of the left adsorber 50) As shown in FIG. 3, the pre-cooling process of the left adsorber 50 is carried out at the same timing as the pre-heating process of the right adsorber 40. The fifth valve 25 is opened, and the third valve 23 and the fourth valve 24 are closed. Then, a heat medium at a temperature (for example, 15°C) at which the first adsorbate 81 is adsorbed by the first adsorbent 43 is passed through the left adsorber piping 52 to adsorb the first adsorbate 81 onto the first adsorbent 43 of the left adsorber 50.
[0059] Also, in the second adsorber 70, a heat medium at a temperature (for example, 60°C) at which the second adsorbate 82 is desorbed by the second adsorbent 73 is passed through the second adsorber piping 72 to desorb the second adsorbate 82 from the second adsorbent 73 of the second adsorber 70.
[0060] Here, in the second adsorber 70, when the second adsorbate 82 of the gas is desorbed from the second adsorbent 73, a positive pressure acts on the second adsorption chamber 70A and thus on the condensation chamber 60A. Then, due to the action of the positive pressure in the condensation chamber 60A, the liquid first adsorbate 81 generated when the first adsorbate 81 of the gas condenses in the condenser 60 and the second adsorbate 82 of the gas flow into the evaporator 30 via the fifth duct 15.
[0061] In this way, in the adsorption heat pump 5, by switching the open / closed states of the first valve 21 to the fifth valve 25, adsorption and desorption are alternately performed in the right adsorber 40 and the left adsorber 50, and cooling heat and heating heat are continuously generated.
[0062] [Operation] The adsorption heat pump 5 according to the embodiment includes an evaporator 30, a first adsorber 10 including a first adsorbent 43 that adsorbs the first adsorbate 81 evaporated in the evaporator 30, a condenser 60 that condenses the first adsorbate 81 desorbed from the first adsorber 10, and a second adsorber 70 provided in the condenser 60 and including a second adsorbent 73 that adsorbs a second adsorbate 82 different from the first adsorbate 81 (see FIG. 1).
[0063] By providing the second adsorber 70 provided in the condenser 60 and including the second adsorbent 73 that adsorbs the second adsorbate 82 different from the first adsorbate 81, in the second adsorber 70, the second adsorbent 73 adsorbs the second adsorbate 82. Therefore, a negative pressure is generated that pulls the first adsorbate 81 and the second adsorbate 82 from the first adsorber 10 to the condenser 60. As a result, the movement of the first adsorbate 81 and the second adsorbate 82 is promoted, and the heat exchange efficiency can be improved without applying additional energy such as in an electric heat pump.
[0064] In the adsorption heat pump 5 according to the embodiment, the second adsorbent 73 does not adsorb the first adsorbate 81.
[0065] Since the second adsorbent 73 does not adsorb the first adsorbate 81, the first adsorbate 81 that has been desorbed by the first adsorber 10 and has heat is not adsorbed by the second adsorbent 73. Therefore, the temperature rise of the second adsorber 70 is suppressed, and the heat exchange efficiency can be improved.
[0066] In the adsorption heat pump 5 according to the embodiment, a diaphragm 65 is provided that partitions the condenser 60 and the second adsorber 70, allows the second adsorbate 82 to pass through, and does not allow the first adsorbate 81 to pass through (see FIG. 1).
[0067] By providing the diaphragm 65 that partitions the condenser 60 and the second adsorber 70, allows the second adsorbate 82 to pass through, and does not allow the first adsorbate 81 to pass through, the approach of the first adsorbate 81 to the second adsorber 70 is suppressed. Therefore, the situation where the first adsorbate 81 that has been desorbed by the first adsorber 10 and has heat contacts the second adsorber 70 and the energy that should be extracted as condensation heat is lost is suppressed. As a result, the heat exchange efficiency can be improved.
[0068] In the adsorption heat pump 5 according to the embodiment, the first adsorbent 43 does not adsorb the second adsorbate 82.
[0069] Since the first adsorbent 43 does not adsorb the second adsorbate 82, the second adsorbent 73 is not adsorbed in the first adsorber 10. Therefore, the second adsorbent 73 acts as a heat medium that assists the heat exchange between the first adsorber 10 and the first adsorbent instead of the first adsorbate 81 that is adsorbed by the first adsorbent 43 and decreases. As a result, the temperature rise of the first adsorber 10 is suppressed, and the heat exchange efficiency can be improved.
[0070] As described above, the adsorption heat pump according to the embodiment has been described based on the embodiment. However, the specific configuration is not limited to this embodiment, and design changes and the like are allowed as long as they do not depart from the gist of the invention according to each claim of the claims.
