Description

Technical Field

[0001] The invention relates to a combined ventilation, exhaust and water outlet valve and an air conditioning cabinet having the combined ventilation, exhaust and water outlet valve. Background Art

[0002] Air-conditioned cabinets are laboratory cabinets in whose interior defined conditions can be set and maintained, especially with regard to temperature and air humidity. It is therefore important to insulate the interior as well as possible to avoid undesired heat exchange with the environment. At the same time, the inner container must also be well sealed to avoid the loss of moisture or water vapor.

[0003] An important field of application of air conditioning cabinets is their use as environmental simulation cabinets for material inspection tests, in particular for checking the response of the material to be inspected to repeated or constantly changing operating points, in particular for material inspection tests of the behavior at changing temperatures and changing moisture concentrations. Unfortunately, such changes in environmental conditions make it necessary to be able to compensate for the pressure and, if necessary, also to discharge the generated condensate from the interior space of the air conditioning cabinet. This is particularly true when temperature jumps that could cause an implosion occur due to planned or unexpected door openings. In order to provide this possibility, known air conditioning cabinets have overpressure and negative pressure valves and condensate drains. However, the disadvantage of this solution is that it makes necessary a large number of connections in the wall surfaces or bottom surfaces that define the interior space, each of which must be sealed and maintained in multiple operating cycles to avoid heat exchange and moisture losses during static operation, that is, when it is not necessary to drain condensate and not to cause pressure compensation. Summary of the invention

[0004] Therefore, the object of the present invention is to provide a combined ventilation, exhaust and water outlet valve, which can not only ensure overpressure compensation and negative pressure compensation as well as condensate management through a single common outlet, but also to provide an air-conditioning cabinet with such a combined ventilation, exhaust and water outlet valve.

[0005] This object is achieved by the combined ventilation, exhaust and water outlet valve and the air conditioning cabinet of the present invention.

[0006] The combined ventilation, exhaust and water outlet valve according to the present invention particularly comprises the following components:

[0007] - for connection to a common water inlet, gas inlet and gas outlet of the air conditioning cabinet. This results in, in particular, that at least part of the valve is flowed through not only by gas, in particular air, but also by water;

[0008] a water reservoir, to which the common water inlet, gas inlet and gas outlet are connected in such a way that the water entering the water reservoir from the common water inlet, gas inlet and gas outlet is guided under the influence of gravity in the direction of the bottom of the water reservoir. Thus, water or condensate is introduced into the water reservoir via the common water inlet, gas inlet and gas outlet and is (initially) stored there, so that a water level is formed in the water reservoir which rises over time. This means in particular that the common water inlet, gas inlet and gas outlet are arranged in the upper region of the water reservoir, preferably at its top or at its upper edge;

[0009] Since the action of gravity on the water is the driving force by which the water is guided through the combined ventilation, exhaust and water outlet valve, its defined orientation in space is defined, in particular its bottom and its top as well as the "up" and "down" directions can be clearly identified;

[0010] a first valve assembly arranged in the first valve chamber, the first valve assembly comprising: a first valve seat, which is penetrated by a channel; and a first closing element, which is pressed against the first valve seat by a first closing force, so that the first closing element closes the channel until the first closing force is overcome, wherein the channel is connected directly or indirectly from the first closing element to the air inlet. This connection is indirect when another channel, such as a hose piece, is connected between the two or the channel widens again before reaching the air inlet, such as reaching the space;

[0011] a second valve assembly arranged in the second valve chamber, the second valve assembly comprising: a second valve seat, the second valve seat being penetrated by the passage; and a second closing element, the second closing element being pressed onto the second valve seat by a second closing force, so that the second closing element closes the passage until the second closing force is overcome; and

[0012] - an outlet opening for air and water, which leads out of the second valve chamber at the level of the upper edge of the second valve seat and establishes a direct or indirect connection between the second valve chamber and the outflow opening for air and water. The outlet opening can be formed by an opening in the wall of the second valve chamber and preferably leads to a pipe or to a drain reservoir, from which the water can flow out, especially driven by the effect of gravity.

[0013] Here, the channel of the second valve seat is directly or indirectly connected to the water reservoir, so that water collected at the bottom of the water reservoir can enter the second channel. This means in particular that the opening through which the water then leaves the water reservoir is located below the second closing element; preferably, the opening is arranged close to the bottom or even directly at the bottom, wherein, however, a threshold value is acceptable.

[0014] Finally, above the maximum water level of the water collected in the water reservoir, there is a direct or indirect connection between the water reservoir and the first valve chamber. The maximum water level is specified for a given ventilation, exhaust and water outlet valve by the height of the water column in the water reservoir at which the pressure of the water column overcomes the second closing force, so that the second closing element opens. Preferably, the connection is above the first and / or second closing element; particularly preferably, the connection extends close to the top, in particular adjacent to the top of the water reservoir.

[0015] A particularly sensitive response behavior and thus a particularly good pressure compensation can be achieved with a variant of the combined ventilation, exhaust and water outlet valve in which the first closing force and / or the second closing force is set by gravity. The response behavior can be further influenced by adapting the density of the first and / or second closing element, which can be achieved by selecting the material from which the respective closing element is made; it has proven to be advantageous if the density of the first and / or second closing element is lower than the density of water.

[0016] A particularly cost-effectively producible variant of the combined ventilation, exhaust and water outlet valve is obtained if the water reservoir, the first valve chamber, the second valve chamber and the outlet reservoir are designed as a continuous injection-molded part.

[0017] When a hose nozzle is arranged at the common water inlet, gas inlet and gas outlet and / or the discharge reservoir at the combined ventilation, exhaust and water outlet valve according to a preferred embodiment of the present invention, or when the common water inlet, gas inlet and gas outlet and / or the discharge reservoir are formed by a hose nozzle, the connection can be particularly good.

[0018] According to an advantageous development of the invention, it is provided that the first closing element and the second closing element are moved in the same direction, in particular upwards, when the respective closing force is overcome.

[0019] When the first closing element and the second closing element are each formed by a ball, the combined ventilation, exhaust and water outlet valve can be designed particularly easily. In particular, the size and material of the balls can also be selected to be the same. When the two closing elements are arranged at the same height, a compact design can also be facilitated.

[0020] A simple and cost-effective embodiment can also be achieved if the first valve seat and / or the second valve seat is formed by a section of a flat intermediate wall having a cylindrical opening extending through the intermediate wall, wherein the cylindrical axis of the cylindrical opening is perpendicular to the plane of the intermediate wall. Such a structure can be easily produced, in particular by injection molding.

[0021] The compact design of the combined ventilation, exhaust and water outlet valve can be further facilitated when the water reservoir and the first valve chamber are separated from each other by a separating wall and when the connection between the water reservoir and the first valve chamber is formed by openings in the separating wall which are located above the height of the first closing element and / or when the water reservoir and the second valve chamber are separated from each other by a separating wall and when the connection between the water reservoir and the channel of the second valve seat is formed by openings in the separating wall which are located below the height of the second closing element.

[0022] Preferably, the air inlet is located above the level of the bottom of the combined ventilation, exhaust and water outlet valve. In particular when there is a very warm and humid atmosphere in the interior of the air conditioning cabinet, it can happen that moisture condenses in the first valve chamber. If the first closing element is open, it can happen that condensate escapes through the passage through the first valve seat. For an air inlet arranged in the bottom, this can lead to condensate dripping out of the air inlet. However, this can be prevented if the air inlet is arranged above the level of the bottom, for example in the outer wall or the top of the combined ventilation, exhaust and water outlet valve. Typically, the amount of condensate produced is small enough that it can evaporate.

[0023] The air conditioning cabinet according to the invention has an interior space defined by inner walls, which interior space is accessible through a door, wherein one of these inner walls forms the bottom of the interior space and one of these inner walls forms the top of the interior space. The air conditioning cabinet is characterized in that there is a common connection piece at the bottom of the interior space, preferably exactly one connection piece for ventilation, exhaust and water outlet, and the above-mentioned combined ventilation, exhaust and water outlet valve according to the invention is connected to this connection piece.

[0034] For the same embodiment, the same reference numerals are used below; however, in order to improve clarity, not all reference numerals are necessarily recorded in all figures of the same embodiment.

[0035] As mentioned above, the effect of gravity on water is the driving force with which it is directed through the combined ventilation, exhaust and water outlet valve, thereby defining its intended orientation in space, and in particular being able to clearly identify its bottom, its height, its top and the "up" and "down" directions.

[0036] Figure 1 A first embodiment of a combined ventilation, exhaust and water outlet valve 100 is shown, which has a first valve chamber 110 , a second valve chamber 120 , a water reservoir 130 and a discharge chamber 140 .

[0037] In the first valve chamber 110 there is a first valve seat 111 with a first channel 112 which leads directly to an air inlet 113. A first closing element 114 designed as a ball rests on the first valve seat 111 and is pressed against the first valve seat 111 by the force of gravity acting as a closing force.

[0038] Adjacent to the first valve chamber 110 is a water reservoir 130, the top of which is penetrated by a common water inlet, a gas inlet and a gas outlet 131 for connecting to the air conditioning cabinet in the form of a hose nozzle. Water 132 is collected at the bottom of the water reservoir, and the water 132 enters the water reservoir 130 through the common water inlet, gas inlet and gas outlet 131.

[0039] exist Figure 1 In the illustrated embodiment, the first valve chamber 110 is separated from the water reservoir 130 by a separating wall 133, wherein, however, the connection between the water reservoir 130 and the first valve chamber 110 is formed by an opening 134 in the separating wall 133, which is above the maximum water level of the water reservoir 130 and in the illustrated example also above the first closing element 114 and even directly adjacent to the top.

[0040] Adjacent to the water reservoir 130 is a second valve chamber 120 in which a second valve seat 121 with a second channel 122 is arranged. A second closing element 124 designed as a ball rests on the second valve seat 121 and is pressed against the second valve seat 121 by gravity acting as a closing force.

[0041] The channel 122 of the second valve seat 121 is in this embodiment directly connected to the water reservoir 130, namely via an opening 135 in a partition wall 136, which separates the water reservoir 130 and the second valve chamber 120 from one another, so that water 132 collected at the bottom of the water reservoir 130 can enter the channel 122. The opening 135 through which the water 132 can then leave the water reservoir 130 is below the height at which the second shut-off element is located; in particular, the opening 135 is also arranged close to the bottom and here even directly at the bottom of the water reservoir 130, wherein, however, a threshold value can also be present.

[0042] Furthermore, it can be seen that adjacent to the second valve chamber 120 there is an outlet reservoir 140 from which water, in particular when driven by gravity, and air can flow out through an outflow opening 141 for air and water designed as a hose nozzle. An outflow opening 143 for air and water is arranged in a partition wall 142 between the second valve chamber 120 and the further reservoir, which outflow opening 143 leads out of the second valve chamber 120 at the level of the upper edge of the second valve seat 121 and establishes an indirect connection between the second valve chamber 120 and the outflow opening 141 for air and water designed as a hose nozzle via the further reservoir 140.

[0043] Figure 2a The combined ventilation, exhaust and water outlet valve 100 is shown in a state of equilibrium. Gravity acts as a closing force on the first closing element 114 and the second closing element 124 respectively and blocks the passage of fluid.

[0044] Figure 2bThe combined ventilation, exhaust and water outlet valve 100 is shown in a state when an overpressure indicated by arrows exists at the common water inlet, gas inlet and gas outlet 131. The overpressure increases the closing force acting on the first closing element 114, but as shown by another arrow, the overpressure resists the closing force acting on the second closing element 124, and when the overpressure is large enough, the closing force is overcome, so that the second closing element 124, which is implemented as a ball, rises from the valve seat 121, and air can flow into the other reservoir 140 through the outlet opening 143, and the air flows out from the other reservoir 140 through the outflow opening 141.

[0045] It should be noted that if Figure 1 As shown, this principle works in almost the same way when water is present in the bottom area of ​​the water reservoir 130 and in the channel 122 of the second valve seat 121. The only difference is that the pressure compensation by the inflow of air through the common water inlet, gas inlet and gas outlet 131 can take place in such a way that water 132 is pressed out of the channel 122 of the second valve seat 121 and, after opening the second closing element 124, flows through the outlet opening 143 into the further reservoir 140, from which the water 132 flows out through the outflow opening 141.

[0046] Figure 2c Shows Figure 1 The combined ventilation, exhaust and water outlet valve 100 is in a state when negative pressure exists at the common water inlet, gas inlet and gas outlet 131 as shown by the upwardly directed arrow. The negative pressure strengthens the closing force acting on the second closing element 124, but it resists the closing force acting on the first closing element 114 and lifts the first closing element 114 from the first valve seat 111, so that ambient air can flow in through the air inlet 113 and the channel 112 and compensate for the negative pressure, whereby the closing element 114 is lowered again.

[0047] Figure 2d Shows Figure 1 The combined ventilation, exhaust and water outlet valve 100 is in a state when additional water flows into the water reservoir 130 through the common water inlet, gas inlet and gas outlet 131 so that the water outlet is activated. The further inflowing water increases the water level of the water 132 located at the bottom of the water reservoir 130 and thus increases the pressure generated by the water column on the bottom of the second closing element 124, until the pressure finally overcomes the closing force set by gravity here and lifts the second closing element 124 from the second valve seat 121, so that water flows into another reservoir 140 through the discharge opening 143, and water flows out of the other reservoir 140 through the outflow outlet 141, whereby the water level of the water 132 in the water reservoir 130 is reduced again, so that the closing element 124 is lowered again.

[0048] Figure 3 A second embodiment of a combined ventilation, exhaust and water outlet valve is shown, which has:

[0049] a first valve chamber 310 in which a first valve seat 311 with a first channel 312 leads indirectly via an air inlet reservoir 350 separated from the first valve chamber 310a by a wall 351 to an air inlet 313 arranged at the top of the combined ventilation, exhaust and water outlet valve 300; and a first closing element 314 embodied as a ball, which is pressed onto the first valve seat 311 by the force of gravity acting as a closing force;

[0050] a water reservoir 330 , the top of which is traversed by a common water inlet, a gas inlet and a gas outlet 331 embodied as a hose nozzle for connection to the air conditioning cabinet;

[0051] - a second valve chamber 320, in which a second valve seat 321 with a second channel 322 is arranged, wherein a second closing element 324 implemented as a ball rests on the second valve seat 321, and the second closing element 324 is pressed against the second valve seat 321 by gravity acting as a closing force; and - a further reservoir 340, from which water, especially when driven by gravity, and air can flow out through an outflow outlet 341 for air and water implemented as a hose pipe nozzle.

[0052] Here, the first valve chamber 330, the water reservoir 330, the second valve chamber 320, the exhaust reservoir 340 and the air inlet reservoir 350 are separated from each other by separation walls 333, 336, 342, 351, respectively, and openings 334, 335, 352 or exhaust openings 343 are provided in these separation walls 333, 336, 342, 351 to produce the necessary connections.

[0053] and Figure 1 and Figure 2a to Figure 2d The combined ventilation, exhaust and water outlet valve 100 of FIG. 1 is only different in that the additional air inlet reservoir 350 allows the air inlet 313 to be arranged above the bottom of the combined ventilation, exhaust and water outlet valve 300 and thus prevents condensate from escaping from the air inlet 313. Apart from this, the structure and function are the same, so that for further details and for a description of the functional mode, reference can be made to FIG. Figure 1 and Figure 2a to Figure 2d , where, in order to transfer the description to Figure 3 , the reference numerals must be increased by 200 each.

[0054] Figure 4a and Figure 4bTwo longitudinal cross-sections of a first embodiment of the combined ventilation, exhaust and water outlet valve 400 implemented as an injection-molded part are shown, in which one of the two longitudinal walls is removed respectively, so that the combined ventilation, exhaust and water outlet valve 400 is shown with a reduced width in a transverse direction extending perpendicular to the height and longitudinal directions, and the internal structure of the combined ventilation, exhaust and water outlet valve 400 can be seen.

[0055] In the combined ventilation, exhaust and water outlet valve 400, the air inlet 413 is formed by a centrally arranged well 460 having well walls 460a, 460b, 460c, 460d which together define a rectangular cross section.

[0056] It should be noted that the well-shaped walls 460a and 460c arranged in the transverse direction extend beyond the expansion of the well-shaped member 460 in the transverse direction, except for the areas of the openings 434, 435 and 443 formed thereby, to the longitudinal wall of the combined ventilation, exhaust and water outlet valve 400, thereby forming a separation wall between the different spaces of the combined ventilation, exhaust and water outlet valve 400.

[0057] The well extends from the top 401 to the bottom 400 of the combined ventilation, exhaust and water outlet valve 400 and communicates with the air inlet reservoir 450 through an opening 415 arranged close to the bottom. The top 452 of the air inlet reservoir 450 has a circular opening as a passage, which simultaneously serves as a valve seat 411 for a first closing element 414, by which the air inlet reservoir 450 and the first valve chamber 410 are separated from each other.

[0058] As described above, in the region of the air inlet reservoir 450, the wall of the shaft in which the opening 415 is arranged is extended to the side walls of the combined ventilation, exhaust and water outlet valve 400 and connected to these side walls. Figure 4a and Figure 4b As shown in the overview, the wall of the well-shaped part in the area of ​​the first valve chamber 410 is extended only to one of the side walls of the combined ventilation, exhaust and water outlet valve 400 and is connected to the one side wall, so that an opening 434 is formed, which establishes a connection with the water reservoir 430.

[0059] Water reservoir 430 Figure 4a The side facing the observer in the middle is adjacent to the well, so that its rear wall is formed by the well, more precisely by the well wall 460b, and its side walls are formed by the extension of the well walls 460a and 460c to Figure 4aWhen there is a negative pressure in the air conditioning cabinet, this is also the case in the first valve chamber due to the connection via the water reservoir 430 and the opening 434. The first closing element 421 opens due to the pressure difference of the ambient pressure present in the air inlet reservoir 450 connected to the outside world via the well 460 and the opening 415, and causes pressure compensation.

[0060] The water entering the water reservoir 430 through the common water inlet, gas inlet and gas outlet 431 collects at its bottom and diffuses into the channel 422 through the opening 435. Above the channel 422 extends an intermediate wall 428, in which an opening forms a second valve seat 421, on which rests a second closing element 424, which in the closed state separates the channel from the second valve chamber 420. If the water level in the water reservoir 430 or the air pressure in the water reservoir 430 in the case of overpressure in the air conditioning cabinet rises sufficiently strongly, the force of gravity pressing the second closing element 424 against the second valve seat 421 is overcome, the second closing element 424 opens and water and / or air enters the second valve chamber 420 until the pressure drops again to such an extent that the second closing element 424 closes again.

[0061] The second valve chamber 420 is connected to another reservoir 440 through an opening 443 extending from the top to the height of the intermediate wall 428, and the wall of the other reservoir 440 is formed by the well-shaped wall 460a and 460c in the direction of the combined ventilation, exhaust and water outlet valve 400. Figure 4b The longitudinal wall 428 is formed by a section extending in the direction of the longitudinal wall (not shown), the longitudinal wall itself and the well side 460d. Since the opening 443 extends to the height of the intermediate wall 428, the water entering the second valve chamber 420 can flow directly into another reservoir 440, from where the water flows out through the outflow 441 for air and water arranged in the bottom and designed as a hose nozzle.

[0062] Obviously, according to Figure 4a and Figure 4b The combined ventilation, exhaust and water outlet valve 400 can be realized very easily by means of a housing having a separation wall and an opening inserted therein, which can be manufactured very easily using injection molding technology.

[0063] Figure 5 A second embodiment of a combined ventilation, exhaust and water outlet valve 200 implemented as an injection molded part is shown, and the combined ventilation, exhaust and water outlet valve 200 has:

[0064] - a first valve chamber 210, in which a Figure 3A first valve seat 211 of the first channel which cannot be seen in the figure leads indirectly to the air inlet 213; and a first closing element 214 which is implemented as a ball and is pressed onto the first valve seat 211 by the gravity acting as a closing force;

[0065] a water reservoir 230 , the top of which is penetrated by a common water inlet, a gas inlet and a gas outlet 231 embodied as a hose nozzle for connection to the air conditioning cabinet;

[0066] - a second valve chamber 220, in which a valve having a Figure 5 a second valve seat 221 of a second channel which cannot be seen in the figure, wherein a second closing element 224 which is implemented as a ball rests on the second valve seat 221 and is pressed against the second valve seat 221 by the gravity acting as the closing force; and

[0067] A further reservoir 340 , from which water, in particular when driven by the effect of gravity, and air can flow through an outflow opening 241 for air and water, which is designed as a hose nozzle.

[0068] Here, the first valve chamber 210 , the water reservoir 230 , the second valve chamber 220 and the drain reservoir 240 are each separated from one another by partition walls 233 , 236 , 242 , in which openings 234 , 235 or drain openings 243 are provided to produce the necessary connections.

[0069] according to Figure 5 The combined ventilation, exhaust and water outlet valve 200 is also characterized in that the first valve seat 211 and the second valve seat 221 are formed by sections of a flat intermediate wall 218, 228 having a cylindrical opening passing through the intermediate wall 218, 228, and the cylindrical axis of the cylindrical opening is perpendicular to the plane of the intermediate wall 218, 228.

[0070] This shows that according to Figure 5 The combined ventilation, exhaust and water outlet valve 200 can be realized very easily by means of a housing having a separation wall and an opening inserted therein, which can be manufactured very easily using injection molding technology.
