Description

[Technical field]

[0001] The present invention relates to a valve unit and a stove. [Background technology]

[0002] Conventionally, there has been known a gas amount control device provided with a harness holding portion that holds a harness extending from a microswitch (see, for example, Patent Document 1). The harness holding portion has a harness storage portion that penetrates in the front-rear direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-23870 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the gas control device described in Patent Document 1, since multiple harnesses are housed in the harness housing, the harness holding portion needs to be large, which causes a problem that the left-right dimension of the gas control device becomes large at the harness holding portion.

[0005] An object of the present invention is to provide a valve unit and a stove that can maintain a valve body in a slim shape. [Means for solving the problem]

[0006] The valve unit of claim 1 is a valve unit that supplies gas to a burner, and is characterized in that it comprises a valve body having an internal flow path through which the gas flows, and the valve body has a harness fixing portion that screws and fixes a first binder that bundles multiple first harnesses extending from a first electrical component.

[0007] The valve body of the valve unit of claim 2 extends in the fore-and-aft direction, the first electrical component is located forward of the harness fixing portion, and a plurality of second harnesses extending from a second electrical component located rearward of the harness fixing portion and the plurality of first harnesses tied together with the first tie may be tied together with the second tie at a position rearward of the harness fixing portion.

[0008] The second binding device of the valve unit of claim 3 may be a covering member that covers an outer periphery of the bundled portion of the plurality of first harnesses and the plurality of second harnesses from the outside and extends along the axial direction of each of the plurality of first harnesses and the plurality of second harnesses.

[0009] The valve body of the valve unit according to claim 4 may be configured such that the first harnesses extending from the first electrical component are wrapped around the valve body with a third binder.

[0010] The stove of claim 5 is characterized by comprising a burner and the valve unit of claim 1 that supplies gas to the burner. Effect of the Invention

[0011] According to the valve unit of claim 1, the first binder for binding multiple harnesses is screwed to the harness fixing part provided on the valve body. This allows the size of the harness fixing part of the valve unit to be compact regardless of the number of harnesses bound by the first binder. Therefore, the valve unit can prevent the valve body from becoming bulky and can effectively organize many harnesses.

[0012] According to the valve unit of claim 2, since the distance between the first and second fasteners can be shortened, the second harnesses extending from the second electric component can be effectively prevented from loosening, and the second harnesses can be easily connected to the second electric component.

[0013] According to the valve unit of claim 3, the first harnesses and the second harnesses can be neatly bundled together by the covering member. Also, the rigidity of the portion covered by the covering member is increased, so that the first and second harnesses can be more effectively prevented from loosening.

[0014] According to the valve unit of claim 4, the plurality of first harnesses extending from the first electrical component can be neatly organized.

[0015] According to the stove of claim 5, since it is equipped with the valve unit of claim 1, it is possible to obtain the effect of claim 1. [Brief description of the drawings]

The front body 201 and the rear body 202 are substantially cylindrical and extend coaxially.

[0026] A gas inlet 24 (see FIG. 7) having a generally short-axis cylindrical shape is provided at the lower part of the rear body 202, generally at the center in the longitudinal direction. The gas inlet 24 opens downward. The gas inlet 24 communicates perpendicularly to the gas flow path. A pair of fixing parts 26, 27 protruding in the left-right direction are provided at both left and right sides of the rear body 202 and at the gas inlet 24. The fixing part 26 is provided with a fixing hole 261 penetrating in the vertical direction. The fixing part 27 is provided with a fixing hole 271 penetrating in the vertical direction. The fixing parts 26, 27 are fixed into the housing 2 with screws, whereby the valve unit 16 is stably fixed into the housing 2.

[0027] A harness fixing part 203 (see Figs. 4 and 6) protruding to the right is provided at the rear end of the right side part of the rear body 202. The harness fixing part 203 is formed in a substantially rectangular parallelepiped shape, and a fixing hole (not shown) extending in the vertical direction is provided in the center of the upper surface. A cable tie 100 (described later) is fixed to the upper surface of the harness fixing part 203 with a screw 38. An earth fixing metal fitting 25 (see Figs. 3 and 7) is provided at the rear end of the rear body 202 so as to protrude rearward.

[0028] As shown in Fig. 7, a spindle 21 is provided in the gas flow passage of the first valve body 20 so as to be movable forward and backward. The spindle 21 is constantly urged forward by a return spring (not shown). A main valve 22 is fixed to the spindle 21. A magnetic safety valve 23 is provided behind the main valve 22. A discharge flow passage 211 is provided near the downstream side of the main valve 22. The discharge flow passage 211 branches off and extends upward from the gas flow passage.

[0030] A push spring 611 (see FIG. 7) is provided inside the casing 61. The push spring 611 constantly urges the moving member 62 forward. A push-push mechanism 63 is provided at the bottom of the casing 61, and determines the forward and backward positions of the moving member 62 alternately when the flame is ignited and when it is extinguished.

[0031] By the ignition operation of the operation button 13, the moving member 62 pushes the spindle 21 backward against the biasing force of the return spring. The spindle 21 moves backward, opening the main valve 22. The main valve 22 opens the discharge flow path 211. The magnetic safety valve 23 is pushed by the spindle 21 to open the gas flow path and maintains the open state. Next, when the pressure on the operation button 13 by the ignition operation is released, the push-push mechanism 63 retreats to a position where the magnetic safety valve 23 can be closed while keeping the main valve 22 open, and locks the moving member 62. Then, when the operation button 13 is pressed by the extinguishing operation and the pressure on the operation button 13 is released, the push-push mechanism 63 releases the lock of the moving member 62 and returns the spindle 21 forward by a predetermined stroke to close the main valve 22.

The left end part of the valve sliding part 88 penetrates the left surface of the flow path forming portion 45. A needle valve 89 is inserted into the valve sliding part 88 from the left.

[0049] The first communication passage 86 extends forward from a gas inlet 861 provided in the front wall portion 432. The front end of the first communication passage 86 is in communication with the rear side of the right end of the cross passage 83 through an opening 832 (see FIG. 12) at a position where it overlaps with the outward passage 81 and the return passage 82 in the left-right direction. Therefore, the first communication passage 86 communicates the inside of the valve chamber 43 with the right end of the cross passage 83. The second communication passage 84 is provided below the first communication passage 86. The second communication passage 84 extends forward from a gas outlet 841 provided in the front wall portion 432 and is coaxially connected to the rear end of the outward passage 81. The second communication passage 84 has a smaller diameter than the outward passage 81. The second communication passage 84 communicates the rear end of the outward passage 81 with the inside of the valve chamber 43.

[0050] The third communication passage 85 extends forward inside the flow passage forming portion 45 from a gas inlet 851 provided in the front wall portion 432. The third communication passage 85 is provided at the same height position as the first communication passage 86, and at a position shifted to the left side of the first communication passage 86 in the protruding direction of the valve chamber portion 43. The front end portion of the third communication passage 85 communicates perpendicularly with the left end side of the rear portion of the valve sliding portion 88. The fourth communication passage 87 extends forward inside the flow passage forming portion 45 from a gas inlet 871 provided in the front wall portion 432. The fourth communication passage 87 is provided between the first communication passage 86 and the third communication passage 85. The fourth communication passage 87 communicates perpendicularly with the cross passage 83 via the narrow passage 833.

[0051] In the front wall portion 432, a valve body 711 (see FIG. 9) of the first solenoid valve 71 comes into contact with and separates from a first valve seat 863 (see FIGS. 8 and 13) provided on the periphery of a gas inlet 861. Therefore, the gas inlet 861 is opened and closed by the valve body 711. A valve body 721 (see FIG. 9) of the second solenoid valve 72 comes into contact with and separates from a second valve seat 853 (see FIGS. 8 and 13) provided on the periphery of a gas inlet 851. Therefore, the gas inlet 851 is opened and closed by the valve body 721.

[0052] 7 and 11, the basic flow of gas in the gas flow passage 200 will be described. Gas that flows rearward through the gas flow passage 302 (see FIG. 7) of the second valve body 30 flows rearward from the gas inlet 811 along the forward path 81, as shown in FIG. 11. The gas flows rearward from the forward path 81 into the second communication passage 84. The gas flows rearward along the second communication passage 84 and flows into the valve chamber 43 from the gas outlet 841. The gas that flows into the valve chamber 43 branches off and flows into each of the three gas inlets 861, 851, and 871.

[0053] Gas that flows into the first communication passage 86 from the gas inlet 861 flows forward along the first communication passage 86 and flows into the cross passage 83 through the opening 832. Gas that flows into the third communication passage 85 from the gas inlet 851 flows forward along the third communication passage 85 and flows into the valve sliding portion 88 through the opening 881. The amount of gas passing through the valve sliding portion 88 is adjusted by the needle valve 89. Gas flows from the valve sliding portion 88 into the cross passage 83. Gas that flows into the fourth communication passage 87 from the gas inlet 871 flows forward along the fourth communication passage 87 and flows into the cross passage 83 through the fine passage 833 (see FIG. 13).

[0054] In this way, the gas that has flowed into the valve chamber 43 branches into three gas flow paths, namely, a first communication passage 86, a third communication passage 85, and a fourth communication passage 87, and then merges again at the cross passage 83. The gas that has flowed into the cross passage 83 flows into the return passage 82 via an opening 831 (see FIG. 12). The gas flows forward along the return passage 82 and flows out from the gas outlet 821.

[0055] The following describes the gas flow rate switching operation by the first solenoid valve 71 and the second solenoid valve 72. The third valve body 40 can switch the gas flow rate in the return line 82 between three stages by opening and closing gas inlets 861, 851 provided in the front wall portion 432 by the first solenoid valve 71 and the second solenoid valve 72, respectively. The three stages are a large flow rate, a medium flow rate, and a small flow rate.

[0056] The case of a large flow rate will be described. In this case, the valve unit 16 separates the valve elements 711, 721 of the first solenoid valve 71 and the second solenoid valve 72 from the first valve seat 863 and the second valve seat 853 (see FIG. 8), and opens both the first communication passage 86 and the third communication passage 85. As a result, the gas that has flowed into the valve chamber 43 branches into each of the first communication passage 86, the third communication passage 85, and the fourth communication passage 87, and is guided to the return passage 82 through the cross passage 83. Therefore, the valve unit 16 can cause the gas to flow out from the gas outlet 821 of the return passage 82 at a large flow rate.

[0057] The case of a medium flow rate will be described. In this case, the valve unit 16 brings the valve body 711 of the first solenoid valve 71 into contact with the first valve seat 863, closing the first communication passage 86. On the other hand, the valve body 721 of the second solenoid valve 72 is separated from the second valve seat 853, opening the third communication passage 85. As a result, the gas that has flowed into the valve chamber 43 branches into the third communication passage 85 and the fourth communication passage 87, and is guided to the return passage 82 through the cross passage 83. Therefore, the valve unit 16 can cause gas to flow out from the gas outlet 821 of the return passage 82 at a medium flow rate.

[0058] The case of a small flow rate will be described. In this case, the valve unit 16 brings the valve bodies 711, 721 of the first solenoid valve 71 and the second solenoid valve 72 into contact with the first valve seat 863 and the second valve seat 853, respectively, to close both the first communication passage 86 and the third communication passage 85. As a result, gas that has flowed into the valve chamber 43 flows only into the fourth communication passage 87, flows into the cross passage 83 via the narrow passage 833, and is guided to the return passage 82. Therefore, the valve unit 16 can cause gas to flow out of the gas outlet 821 of the return passage 82 at a small flow rate.

[0059] In this manner, in the valve unit 16 of this embodiment, the gas flow rate to be discharged to the second valve body 30 can be switched in three stages in the gas flow path 200 provided inside the third valve body 40. As a result, the gas flow rate discharged from the nozzle 34 of the second valve body 30 can be switched in three stages, so that the heat of the left burner burner 6 can be switched in three stages: high heat, medium heat, and low heat. As a specific structure of the gas flow path 200, the forward path 81 and the return path 82 extending in the front-rear direction are arranged vertically, and a cross-section path 83 is provided in the left-right direction between the vertical height positions of the forward and backward paths. Then, the first communication path 86, the third communication path 85, and the fourth communication path 87 extending forward from the inside of the valve chamber 43 are each connected to the cross-section path 83, and the cross-section path 83 is connected to the return path 82. In this embodiment, by adopting such a flow path configuration, the third valve body 40 does not protrude significantly in the left-right direction, and the length can be shortened in the front-rear direction as well. Therefore, the valve unit 16 can be maintained in a slim shape that does not protrude too much in the left-right direction and is not long in the front-back direction either. Therefore, the valve unit 16 can avoid interference with other components arranged on both the left and right sides inside the housing 2 of the stove 1.

[0060] 7, in the valve unit 16, the main body portion 41 of the third valve body 40 is disposed directly above the rear body 202 of the first valve body 20. The left-right width of the main body portion 41 is approximately the same as the left-right width of the rear body 202. Therefore, when the valve unit 16 is viewed from directly above as shown in FIG. 2, the fixing portions 26, 27 provided on both the left and right sides of the rear body 202 of the first valve body 20 are not hidden by the main body portion 41 of the third valve body 40.

[0061] In other words, the valve chamber portion 43, which is wide in the left-right direction of the third valve body 40, is not located directly above the rear body 202, and the main body portion 41, which is slim in width in the left-right direction, is located directly above the rear body 202. This makes it possible to insert a tool into the fixing holes 261, 271 of the fixing parts 26, 27 from directly above the valve unit 16 when screwing and fixing the fixing parts 26, 27 into the housing 2 of the stove 1, making the screwing work easier. In addition, in the gas flow passage 200, the first communication passage 86 communicates the inside of the valve chamber 43 with the right end of the tolerance passage 83 at a position where it overlaps with the outward passage 81 and the return passage 82 in the left-right direction. This allows the return passage 82 and the first communication passage 86 to approach each other in the up-down direction via the tolerance passage 83. Therefore, the valve unit 16 can make the main body 41 of the third valve body 40 have a slimmer shape in the up-down direction as well. In addition, when the third valve body 40 is molded using a mold, a first pin for forming the outward passage extending in the front-rear direction and a second pin for forming the return passage extending in the front-rear direction are arranged in the mold so as to be parallel to each other in the up-down direction, a third pin for forming the tolerance passage is arranged in the left-right direction at a position in the height direction between the first pin and the second pin, and a fourth pin for forming the first communication passage is arranged facing the third pin at a position where it overlaps with the first pin and the second pin in the left-right direction. In this case, the outgoing path 81, the return path 82, the tolerance path 83, and the first communication passage 86 are formed by the simple operation of simply removing the first to fourth pins from the mold in the respective directions, thereby eliminating the need to cut the flow paths in the third valve body 40 in order to form the flow paths.

[0062] 2 to 4, a method of bundling various harnesses extending from the valve unit 16 will be described. A plurality of harnesses extend from a plurality of locations of the valve unit 16. The harnesses in this embodiment may be single-wire or double-wire. As shown in FIG. 6, a terminal 90A is connected to the microswitch 28 fixed to the right side surface of the casing 61 of the operation mechanism 60, and a harness 91 extends rearward from the terminal 90A. As shown in FIG. 5, a terminal 90B is connected to the microswitch 29 fixed to the left side surface of the casing 61, and a harness 92 extends rearward from the terminal 90B. A terminal 90C is connected to the connection terminal portion 713 of the first solenoid valve 71 of the solenoid valve unit 70, and a harness 94 extends from the terminal 90C. A terminal 90D is connected to the connection terminal portion 723 of the second solenoid valve 72, and a harness 95 extends from the terminal 90D. That is, in the valve unit 16, at least these four types of harnesses 91, 92, 94, and 95 extend from the front and rear sides.

[0063] In this embodiment, the harnesses are attached to the valve unit 16 while being bundled together as described below, thereby enabling a plurality of harnesses to be effectively bundled together. First, the two types of harnesses 91, 92 extending from the microswitches 28, 29 are bundled together with a resin cable tie 100. The cable tie 100 includes a fixing portion 101 and a binding portion 102. The fixing portion 101 is formed in a long and narrow flat plate shape in a plan view, and is provided with a fixing hole (not shown) penetrating in the vertical direction at one end in the longitudinal direction. A screw 38 (see FIG. 6) can be inserted into the fixing hole from above.

[0064] The binding portion 102 is provided at the other end of the fixing portion 101, and binds the harnesses 91, 92 from the periphery. One end of the fixing portion 101 of the binding band 100 binding the harnesses 91, 92 is placed on the upper surface of a harness fixing portion 203 provided on the first valve body 20, and a screw 38 is inserted into a fixing hole provided in one end of the fixing portion 101 and fastened to a fixing hole provided in the upper surface of the harness fixing portion 203. This allows the harnesses 91, 92 to be fixed to the upper surface of the harness fixing portion 203 via the binding band 100.

[0065] Next, the harnesses 91, 92 located between the microswitches 28, 29 and the harness fixing portion 203 are tied to the outer circumferential surface of the rear body 202 of the first valve body 20 with a tie band 150 so as not to slacken. The tie band 150 is formed in an annular shape, and by tying it to the outer circumferential surface of the rear body 202, the harnesses 91, 92 can be bundled together more neatly. The harnesses 91, 92 located between the tie band 150 and the tie band 100 may be further tied with a tie member 155 (see FIG. 6). The tie member 155 may be, for example, a resin tape wound around the outside of the harnesses 91, 92, or a cylindrical covering member.

[0066] Next, the harness 94 extending from the first solenoid valve 71 and the harness 95 extending from the second solenoid valve 72 are bundled together at a substantially central position in the left-right direction. At the same time, the harness 96 consisting of the harnesses 91 and 92 bundled together with the cable tie 150 is pulled out to the rear side, and these harnesses 94, 95 and 96 are bundled together and bundled with the bundling member 160. As a result, the valve unit 16 can shorten the distance between the bundling member 160 and the first solenoid valve 71 and the second solenoid valve 72, so that the harnesses 94, 95 extending from the first solenoid valve 71 and the second solenoid valve 72 can be effectively prevented from loosening. In addition, the valve unit 16 can easily connect the terminals 90C, 90D of the harnesses 94, 95 to the connection terminal portions 713, 723 of the first solenoid valve 71 and the second solenoid valve 72.

[0067] The bundling member 160 may be, for example, a resin tape wound around the outside of the harnesses 94 to 96, or a cylindrical covering member, and preferably extends along the axis of each of the harnesses 94 to 96. This increases the rigidity of the portion covered by the bundling member 160, further preventing the harnesses 94 to 96 from slackening. The bundling member 160 can bundle the harnesses 94 to 96 more neatly.

[0068] Furthermore, the harnesses 94-96 bound by the binding member 160 are pulled rearward, and the terminal 90E is connected to the rear end thereof. It is more preferable to bind the harnesses 94-96 near the terminal 90E with the binding member 170. The binding member 170 is preferably made of the same material as the binding member 160. Also, a predetermined harness 961 of the harnesses 94-96 may be folded back with the binding member 160 and fixed to the earth fixture 25 with a screw 251 (see FIG. 3).

[0069] As described above, the stove 1 of this embodiment includes valve units 15 and 16 that supply gas to the right burner 5 and the left burner 6. The valve unit 16 for the left burner 6 includes a first valve body 20, a second valve body 30, and a third valve body 40 that have a flow path for gas inside. The microswitches 28 and 29 are attached to the valve unit 16, and the harnesses 91 and 92 extend from the microswitches 28 and 29. The cable tie 100 ties the harnesses 91 and 92 extending from the microswitches 28 and 29. The first valve body 20 includes a harness fixing portion 203 that screws and fixes the cable tie 100 that ties the harnesses 91 and 92. This allows the size of the harness fixing portion 203 of the valve unit 16 to be compact, regardless of the number of harnesses 91 and 92 bundled by the cable tie 100. Therefore, the valve unit 16 can prevent the first valve body 20 from becoming thicker, and can effectively organize many harnesses 91, 92.

[0070] The first valve body 20 extends in the front-rear direction. The micro switches 28, 29 are located forward of the harness fixing portion 203. The harnesses 94, 95 extend from the first solenoid valve 71 and the second solenoid valve 72, which are located rearward of the harness fixing portion 203. These harnesses 94, 95 and the harnesses 91, 92 tied with a tie band 100 (collectively referred to as "harness 93") are tied with a tie member 160 at a position rearward of the harness fixing portion 203. This shortens the distance between the tie band 100 and the tie member 160, effectively preventing the harnesses 94, 95 extending from the first solenoid valve 71 and the second solenoid valve 72 from loosening. Also, the harnesses 94, 95 can be easily connected to the first solenoid valve 71 and the second solenoid valve 72.

[0071] The bundling member 160 covers the outer periphery of the bundled harness 93 and the bundled harnesses 94 and 95 (collectively referred to as the "harness 96"). This allows the harness 96 to be neatly bundled. Furthermore, the bundling member 160 is a covering member that extends along the axial direction of each of the harnesses 96. This allows the bundling member 160 Since the rigidity of the covered portion is increased by this, loosening of the harness 96 can be prevented more effectively.

[0072] The harnesses 91, 92 extending from the microswitches 28, 29 are wrapped around the first valve body 20 with a cable tie 150. This prevents the harnesses 91, 92 located between the microswitches 28, 29 and the harness fixing portion 203 from becoming loose, allowing the harnesses to be bundled together even neater.

[0073] In the above description, the microswitches 28, 29 are an example of a "first electrical component" of the present invention. The first valve body 20 is an example of a "valve body" of the present invention. The harnesses 91, 92 are an example of a "first harness" of the present invention. The harnesses 94, 95 are an example of a "second harness" of the present invention. The cable tie 100 is an example of a "first tie" of the present invention. The tie member 160 is an example of a "second tie" of the present invention. The cable tie 150 is an example of a "third tie" of the present invention.

[0074] The present invention is not limited to the above embodiment, and various modifications are possible. The stove 1 is a table stove with a grill, but it may be a built-in stove. The grill chamber does not have to be provided. The number of stove burners is not limited to two, and may be one, or three or more.

[0075] The gas flow passage 200 in the third valve body 40 in the above embodiment includes three communication passages (first communication passage 86, third communication passage 85, fourth communication passage 87) that communicate with the cross passage 83, and the gas flow rate can be switched in three stages by opening and closing one or two of the communication passages with the first solenoid valve 71 and the second solenoid valve 72, but the number of communication passages that communicate with the cross passage 83 may be three or more. In this case, the gas flow rate can be switched in even more stages (three or more stages).

[0076] A harness fixing part 203 is provided at the rear end of the right side part of the rear body 202 of the third valve body 40, but the position of the band fixing part is not limited to that in the above embodiment. For example, it may be provided on the front body 201 instead of the rear body 202, or on the first valve body 20 or the second valve body 30. The shape and number of the band fixing part are also not limited to those in the above embodiment.

[0077] In the above embodiment, the harness 96 obtained by bundling the harnesses 93 to 95 is bound by the binding members 160 and 170, but the harness 96 may be bound at another location by a binding member depending on the length of the harness 96. Also, the binding member 170 may be omitted. [Explanation of symbols]
